Abstract: 1506214 Ultrasonic inspection devices CANAC CONSULTANTS Ltd/CANAC CONSULTANTS LIMITEE 28 July 1975 [9 Aug 1974] 31516/75 Heading G1G An elongate probe assembly, Fig. 1, for ultrasonically testing thermit butt welds in rail tracks comprises two outer ultrasonic probes 1, 10 symmetrically disposed on opposite sides of a central probe O, the beam of each probe (when the assembly is positioned on a rail) being directed to the underside of the rail track directly beneath the central probe O, and further comprises pairs of inner ultrasonic probes (e.g. 2, 9) symmetrically disposed about the central probe O whose beams are symmetrically directed to a point intermediate the top and bottom of the rail. In operation, one probe of each pair acts as a transmitter and the other as receiver with the single probe O acting as transmitter and receiver. As described probes 1- 10 comprise transducers 21 mounted on triangular prisms 22 in sealed containers 24 that are biased by springs 25 acting against a sheet metal housing 20. The central probe O has a parallel sided or flat prism (not shown). Liquid complant is supplied by pipe 28 at outlets 27. Probes 1-10 operate as pairs, one as transmitter the other as receiver, interchangeably, symmetrically displaced from the central probe O which acts as a weld locator. As displayed on a CRT, the back wall echo received by the probe O disappears when directly over a weld. When located, the weld may be tested for non- adhesion and/or cracks, Figs. 2-5 (not shown), by detecting the blockage of the acoustic path between probes 1 and 10 and for regions of porosity, Figs. 6-9 (not shown), by the formation of an acoustic path between probes 2-5 and corresponding ones of probes 6-9. A system mounted on a rail test car comprises an assembly 114, 115 on each of two rails and has probe selectors 116, 117 connecting probe pairs (e.g. 1 and 10) or the central probe with the pulser-receiver 118. Spurious noise and echos outside the time range pertinent to the probes being used are gated out by a unit 119 and the echo signals (or the absence or disappearance thereof) may be displayed on a CRT 122 and pen recorder 121.

Abstract: 170,208. McAteer, J. W. Nov. 8, 1920. Guarding against unauthorized use.-A lock for the steering-column or like movable part of a motor or other cycle, motor-car, &c., comprises a spring-pressed locking-bolt j which is adapted to be retracted from its operative position by the differential action of internal and external screw-threads on an operating plug or key q, said screw-threads engaging respectively with the bolt and with the main body a or a part g mounted thereon. The bolt is squared, as at m, to slide within the body a, and is pressed forward by a spring o abutting against the part g and against a cross-pin n. The part g is retained in position by a grub-screw p. The threads or combination of threads on the bush g and the bolt end k may be varied, and by turning the bolt through 90� about its axis, a further series of combinations may be obtained. To prevent turning of the plug owing to the vibration of the vehicle, the upper edge of the body a and bush g may have radial notches for engagement by a spring-pressed nose on the plug.

Title: Method of treating matte tin plate to prevent darkening
IPC: C25D5/48
Filed: 1962-08-17
Abstract: A method of making matte tin plate, which will not turn yellow on storage and which will not blacken during baking incident to lacquer coating or lithographing, comprises electroplating a tin coating on to a sheet-steel base giving it a matte appearance, heating the tin plate to a temperature below its melting point in the range 420-445 DEG F. for a time not exceeding 10 seconds at the selected temperature, then immediately quenching the tin plate and subjecting it to electrolysis as cathode in an aqueous solution of an alkali metal dichromate containing substantially 24 grams of the dichromate per litre.  In an example this solution contained 24 gs./l. sodium dichromate adjusted to a pH of 4.7 at a temperature of 125 DEG F. and a current of 52 coulombs per sq.ft. of the strip was passed.  After emerging from the treating solution, the strip was rinsed with cold water, dried with steam and electrostatically oiled. The strip did not darken when baked at a lacquer-curing temperature of 375 DEG F. for 13 minutes.

Filed: 1938-11-02
Abstract: 522,001. Two-stroke cycle engines. RICARDO, H. R. Nov. 2, 1938, No. 31713. [Classes 7 (ii) and 7 (vi)] Terminal scavenging ports E are supplied from a reciprocating pump H driven from, but out-of-phase with, the crankshaft. The pump delivery stroke commences at or about, but preferably slightly before, the commencement of the scavenging period and ends after the scavenging ports have been closed. Transfer through the passage G is controlled by a rotary or slide valve M, which closes the passage at the end of the pump delivery stroke, thus trapping air pressure in the scavenging belt. The valve M also controls the inlet of air to the pump cylinder, and the pump piston is axially guided by a fixed rod O<2>. The valve M is driven from a crank-pin R<1> engaged by one arm S of a cruciform link driven by an eccentric K<1> on the engine crank-shaft. The link also has an arm S<1> for driving a dynamo and other auxiliaries, and arms S<2>, S<3> for driving the valve cam-shaft and oil-pump respectively.
