Visit this record in UMA's new catalogue at: https://archives.library.unimelb.edu.au/nodes/view/68648Technical drawings from Crankless Engines Ltd, 2515 in number. See also reference number 1991.0074 University of Melbourne Department of Civil Engineering for more on Michell.
Most of the drawings are identified by an engine number (CE…), part number (often several on each item), and drawing number that usually corresponds to a chronological order. Drawing numbers that begin with the letters “SK” usually correspond to sketches, proposed or draft plans. Three drawings have drawing numbers that begin with “MC”, which appear to be designs associated with the University of Melbourne rather than Crankless Engines, Ltd. Some plans have been given a job number rather than an engine number, but this seems to be simply an earlier version of the same filing practice,
phased out in 1922.
Those plans that have not been given a CE or part number but have been
given a drawing number are usually plans of the general arrangement of a
particular engine, named in the title, although there are exceptions to this.
The company name changes around 1924 from Crankless Engines (Aus) Pty
Ltd to Crankless Engines Limited, although there is considerable overlap around that. Apart from showing the change in company status to a publicly listed company, there does not seem to be any other significance attached to that identifier. The date range usually refers to the date that the plan has been drawn (earlier date) and the date that it was approved (later date). A number of plans were cancelled, and revised plans drawn to replace them. These have been noted in Scope and Content.
Plans that were drawn or traced by AGMM (Michell), PEI (Irving), RWGM, JWS or TLS have been noted as such because they are noteworthy persons. Blueprints have also been noted. Some items are missing particular descriptors, because those descriptors were
not provided on the item itself. Unless otherwise stated, measurements are in inches
There are a number of brochures, reports and a photograph attached to the
collection that do not seem immediately connected with AGM Michell, although loose associations may be inferred from the historical note. The collection also contains photocopies of agreements made with Michell or Crankless Engines, Ltd.115167

Visit this record in UMA's new catalogue at: https://archives.library.unimelb.edu.au/nodes/view/58729Anthony G M Michell (1870 – 1959) is renowned internationally for his brilliant invention of the Tilting Pad Thrust Bearing, which carries the fore-and-aft load on ship propeller shafts. It overcame lubrication failure, which was a major shortcoming of existing bearings hindering ship development in the early twentieth century.
The Michell bearing rapidly spread worldwide, notwithstanding a competing invention and patent, which effectively locked out the US market. The commercialisation process of the thrust bearing was undertaken through a joint venture of Michell Bearings Ltd with H B Scott that was based in Newcastle on Tyne, UK.
The genius of Michell’s thrust bearing lies in it having one of the mating faces replaced by a bracelet of tilting pads that face the direction of circular motion and adjust themselves to a wide range of fluid dynamic loadings. In this way even severe operating conditions are supported without lubrication break down and consequent bearing failure.
Michell is remembered as one of the School’s most distinguished alumni graduating with a Bachelor of Civil Engineering in 1895 and a Master of Civil Engineering in 1899. He was awarded the Kernot medal of the University of Melbourne in 1939 and the 1942 Watts Medal from the Institute of Mechanical Engineers

Turbulent Boundary Layer Flow over a Flat Plate Vibrating with Transverse Standing Waves
No full textBureau of Ships Fundamental Research Program SR-009-01-01; Office of Naval Research Contract Nonr 710(38)An attempt is made to show theoretically that the drag caused by a turbulent boundary layer on a smooth flat plate vibrating with low amplitude transverse standing waves is the same as for a non-vibrating plate provided the wave celerity of the component traveling waves is greater than about 3.5
times the free stream velocity. Experiments conducted in a water tunnel with a rectangular Cross-section having one vibrating wall showed no measurable
change in boundary layer velocities, as compared to non-vibrating conditions,
for frequencies ranging from 15 to 122 cps and free stream velocities ranging
from 2.4 to 15 fps. The lowest wave celerity to free stream velocity ratio tested was 2.54.David Taylor Model Basin Department of the NavyMercer, Albert G.. (1962).

Tentative Design Procedure for Riprap-Lined Channels-Field Evaluation
No full textAs a result of the basic study outlined in the previous report (1)*,
a field evaluation of riprap-lined channels designed in accordance with
the procedures outlined therein was recommended to determine the effectiveness
of the procedures at scales considerably larger than any that can be
produced in the laboratory.
Because drainage channels are constructed as the need arises, and the
necessity for a riprap lining depends on the local circumstances, considerable
time may elapse before a substantial number of channels is available
for examination. In addition, hydrologic events of the magnitude necessary
to provide an effective test of the riprap's stability are relative infrequent.
These conditions have militated against collection of sufficient
data to thoroughly test the procedures developed in the study. Specifically,
five channels have been proposed since the completion of the report outlining
these design procedures; four of these have been constructed and one is
still in the planning stage. Of the four completed projects, two were intended
for stream relocations involving relatively large discharges and two
are roadside drainage ditches. Some data have been obtained for these four
channels, but in only two cases has the discharge been large enough to approach
the design discharge and provide a reasonably definitive test. A
detailed description of each of these channels and the available data on the
results of the discharges which have occurred are given in the appendices.Highway Research BoardAnderson, Alvin G.. (1973). Tentative Design Procedure for Riprap-Lined Channels-Field Evaluation. Retrieved from the University Digital Conservancy, https://hdl.handle.net/11299/114856
Nobel Laureate Anthony J Leggett: A scientometric portrait
No full textThis paper attempts to analyse the publication productivity of Anthony J. Leggett, the 2003 Nobel Prize winner in physics. His contributions peaked in 1987, 1994, and 1998 with 10 papers each. He had 194 publications during 1964 - 2004 in domains like Superfluid 3He (65), Foundations of Quantum Mechanics (36), Dissipative Quantum Systems (24), Atomic Alkali Gases (18), and Miscellaneous (51)which were analysed for authorship pattern with his 70 collaborators. Most active collaborators with Anthony J Leggett were: A. Garg with six papers and A. O. MCaldeira, D. M. Ginsberg, D. J. Vanharlingen , F. Sols, S.Takagi and D. A. Wollman with five papers each. His productivity coefficient was 0.60 which clearly indicates that his productivity
increased after 50 percentile age. The highest degree of collaboration (1) for Anthony J. Leggett was found during 1964, 1971 and 1983. Journals have been the most preferred channel of communication, where as many as 139 papers out of 194 have been published. The core journals publishing his papers were: Phys. Rev. Leu. (42), Phys. Rev. B (9), J. Low Temp. Phys. (8),Phys. Rev. A (7), Ann. Phys. (6), Foundations of physics (6), J. Phys.(5), Prog. Theor: Phys. (5), and Rev. Mod. Phys. (5).Publication density was 3.02 and publication concentration was 3.59
