Abstract: 1,153,168. Ultrasonic inspection apparatus. AUTOMATION INDUSTRIES Inc. 29 Dec., 1966 [29 Dec., 1965], No. 58190/66. Heading H4D. Apparatus for ultrasonically inspecting railway vehicle wheels comprises a turntable 26 for supporting a wheel 18, means for centring the wheel on the turntable, and an adjustably mounted transducer assembly 58 for detecting wheel flaws by the pulse-echo method. The wheel is carried to the inspection station by a conveyer stem 16 and raised into a test position by a pneumatic cylinder 20 operating on the turntable shaft 22. Three combination pneumatic/hydraulic jacks 32 equi-spaced around the wheel rim are then actuated to centralize the wheel, the hydraulic sections of the jacks being coupled in a closed loop circuit (Fig. 3, not shown) to equalize the forces exerted by the jacks on the wheel rim. The transducer assembly 58 is brought against the wheel rim by a pneumatic cylinder 60, and table 26 is rotated for the inspection. A spray marker 74 is actuable to mark a flawed area of the wheel. In an automatic inspection sequence interlocks (e.g. between the turntable lift operation and the conveyer system), prevent any operation from occurring out of sequence. Transducer details.-The assembly 58 may comprise vertically and horizontally directed arrays of transducers acoustically coupled to the wheel by water jets, or contact-coupled transducers, or an ultrasonic transducer wheel.

Title: Overcap for an aerosol dispenser
IPC: B05B9/04
Filed: 1972-12-18
Abstract: 1385808 Tamperproof closures SUNBEAM PLASTICS CORP 18 Dec 1972 [27 Jan 1972] 58339/72 Heading B8T A tamperproof and childproof aerosol dispenser 20 has a body 21, a breast portion 22 and a valve 23 with a feed tube 24 and dispensing nozzle 25, the valve 23 being retained by an annular sealing collar 26. The overcap 27, made from resilient material, comprises an outer wall 28 and an inner concentric skirt 29, with an inwardly turned retaining lip 30 frictionally engaging below collar 26 when the cap is in place on the can. The lip 30 is slotted with a pair of lugs 31 on opposite sides of the slot. Overcap 27 also has a rotatable locking element 32 with a cylindrical body 33 which fits rotatably into a well 34 formed in overcap 27 between wall 28 and skirt 29. The upper end of lock 32 has a head 35 fitting into counterbore 36 of the top 37 of cap 27, the lock body extending through well 34 and carrying an oblong key 38 at its end, which locates between lugs 31 on skirt 29. Thus, rotation of lock 32 to its "open" position causes lugs 31 to spread apart and release lip 30 from below collar 26, permitting overcap 27 to be removed from can 20. Since the oblong key 38 has rounded ends, and skirt 29 is resiliently biased, release of pressure on lock 32 will permit the skirt 29 to return to its normal, closed position, when it can be clipped back over collar 26 to replace overcap 27 after use. To ensure cap 27 is tamperproof, a frangible tab 41, moulded in head 35, is located in recess 42 in the top 37 of cap 27, and lock 32 cannot be moved into the "open" position without breaking tab 41 off. The locking device 32 is retained in position in the overcap by dogs 39 which snap below lower edge of well 34 on initial assembly.

Abstract: 1418310 Heat-treating carburized steel USS ENGS &ÀCONSULTANTS Inc 22 Dec 1972 [3 Jan 1972] 59434/72 Headings C7A and C7U. Steel containing not more than 0.4% C is carburized at a temperature above 1700‹C to produce a maximum in the case of 0.8-1.2%C, after which it is quenched to below M s  of the case, and reheated into the bainite region to transform all residual austenite. It is then heated into the temperature range of A3 (of the core) - (A3 + 100‹F), held only for sufficient time to permit temperature equalization throughout the crosssection and quenched to produce a martensitic case. In a modification the steel is quenched directly from the carburizing temperature into the bainite region, while in either process a final tempering step may be carried out conventionally e.g. 1 hour at 400‹F. The process is particulalry applied to gears, bearing races and bushings.

Patent GB-2014014-A (GB)
Title: Voltage contrast in scanning electron microscopy
IPC: H01J37/26
Filed: 1979-01-22
Abstract: In using a scanning electron microscope to examine integrated circuits, it is desirable to observe only the brightness of each point as affected by the voltage at that point in the integrated circuit being examined, and to eliminate the brightness effects of surface topography, composition, etc. To do this, a flip-flop 24 changes state on each scan line, the scanning being in a TV-like raster. This applies electrical bias to the circuit under test on alternate scan lines. Each scan-line-with- bias output is delayed by 1 line scan period in delay line 28, and has the next scan line (without bias) signal subtracted from it by a difference amplifier 31 to give a resultant signal in which effects due to causes other than voltage contrast are cancelled out. The resultant display is a TV-like display which can be view directly and shows only the voltage contrast effects. <IMAGE>
