Title: Anti-theft devices
IPC: B60R25/021
Filed: 1973-11-20
Abstract: 1455444 Anti-theft locks NEIMAN SA 20 Nov 1973 [24 Nov 1972] 53731/73 Heading E2A [Also in Division B7] An anti-theft device (Fig. 1) comprises a body or stator 2 secured in a casing 1, which' is part of a steering column of a vehicle, by a pin or detent 4 provided with a spring 5 which, after suitable alignment, resiliently engages in an orifice formed in said casing. When motor 3 of the cylinder lock is adjusted to a particular position by means of a key, the inner end of pin 4 may be retracted  into a recess in 3 by applying pressure to the outer end of pin 4 with an appropriate tool which is inserted through said orifice in the casing; with pin 4 thus retracted, the lock may be removed from the casing. Access to the orifice in the casing (Fig. 2) is restricted by the provision of guard 7 which only permits the insertion of the correct right-angled tool 8. Access to locking pin 4 may also be rendered difficult (Fig. 5) by permitting displacement of pin 4 only through the intermediary of an easily deformable element 18. The anti-theft device may also be adapted to make use of the key passage (Fig. 7) to receive the end of a plate-like detent 21 which is held in its normal locking position by springs 22 and 23, which embodiment may be combined with the present invention. A further embodiment of the anti-theft device (Figs. 9 and 10) which also may be combined with the invention consists in interposing in stator 2 a slide plate 25, e.g. of hardened steel, the displacement of which is effected by can 24 which can be an integral part of an operating can controlling the displacement of the bolt 6 (Fig. 1). Slide plate 25 is biased by a spring 26 and serves as a stop for pin 4 when the latter is thrust against it by spring 5. A hole 28 in plate 25 receives pin 4 when can 24, for a selected position of rotor 3 and its key, effects the suitable displacement of plate 25.

A gear-wheel is cold-formed from a cylindrical blank by two series of tool projections, the projections causing metal from the two edges of the blank periphery to be displaced axially inwardly during the cold-forming. The projections can be formed in a platen 3, 4, with two such platens being reciprocated on opposite sides of the blank to roll teeth into its periphery. Projections 2 are provided at the edges of each platen and are formed in groups which gradually increase in size from the leading end 3 of the platen. The projections are tapered inwardly, and progressively extend towards each other until continuous teeth 2<SP>1</SP>, 2<SP>11</SP>, and finally 2<SP>111</SP>, are formed.

Title: Method for recovering argon as contained in the blowing gases coming from an argon-oxygen decarburization converter

Filed: 1974-12-20
Abstract: 1490098 Recovery of argon used in refining stainless steel N U RINALDI 20 Dec 1974 [28 Dec 1973 30 May 1974] 55116/74 Heading C7D In the argon-oxygen decarburization (AOD) of stainless steels in a converter, the off-gases, mainly CO and Ar, are removed from the converter mouth by suction whilst being protected from the atmosphere by a jacket of gas, preferably Ar, CO 2 , steam or a mixture of these, such that the Ar can be subsequently separated from the other gases. The off-gases are sucked through duct 4 in which the jacket of gas is introduced through radial nozzles 6'; the stream then being treated in Venturi scrubber 7 and exhauster 8 prior to compression at 10. The compressed gas has CO 2  removed in absorber 11 (using, e.g. hot potassium carbonates), has CO removed in installation 12 and the remaining Ar is stored in tank 14 and recycled to the converter 1. The installation 12 is either (a) a CO- absorber, using a cuprammonium solution (e.g. the sulphate) after which the stripped gas is scrubbed at 13 to remove NH 3 ; or (b) a lowtemperature fractionation column wherein Ar can be separated from the other gases by virtue of its greater density (in which case the scrubber 13 is not used). The CO 2  removed at 11 can be recycled to form the jacket gas. In further modifications the jacket of gas can be surrounded by a second jacket, e.g. of N 2 ; the absorber 11 is dispensed with and both CO and CO 2  are removed by the cuprammonium solution; and the absorber 11  may be replaced by molecular sieves.

Title: Method of adjusting the swept gain of an ultrasonic pulse-echo instrument to maintain flaw detection sensitivity substantially independent of flaw depth in a workpiece
IPC: G01N29/40
Filed: 1970-11-26
Abstract: 1336160 Ultrasonic inspection devices DR J & H KRAUTKRAMER GES FUR ELEKTROPHYSIK 26 Nov 1970 [2 Dec 1969] 56295/70 Heading H4D  To enable the swept gain of an ultrasonic pulse-echo flaw-detector to be set up so that the flaw-detection sensitivity is independent of flaw depth in a test specimen, a scale 24 on which is inscribed a calibration curve 15 representing the theoretical or empirically derived echo amplitude versus echo time for an "infinite" reflector (i.e. one bigger than the ultrasonic beam cross-section) is produced on or placed in front of the flaw-detector's echo-amplitude versus time display screen and the gain and swept gain controls are adjusted until the peaks of a series of actual echoes 16, obtained by multiple reflection from the specimen back wall or obtained with a probe successively at various distances from the specimen end or from a hole machined in the specimen, lie on the calibration curve. The displayed heights of echoes from much smaller reflectors such as flaws will then be substantially independent of echo time since the law of variation of echo height with time is not the same for small reflectors as for an "infinite" reflector. The scale 24 may be of transparent material, flat or slightly curved, on a backing mount 23, and carries additional lines 18, 19, 20 (representing the echo heights from cylindrical test holes of, e.g. 2, 1 and 0À5 mm. diameter). The invention is applicable to flaw-detection using longitudinal or transverse waves. If the probe is an angle type the echo series is obtained from specimen end 21 (Fig. 4) with the probe successively at positions I, II, III &c., which are ¢, 1, 1¢ &c. skip distances from end 21, or the echoes are obtained similarly from a machined hole. Alternatively a Y-cut crystal probe with its beam axis normal to the back wall is used to generate multiple backwall echoes for calibration purposes and is then replaced by the angle probe for flaw-detection, allowance being made for any sensitivity difference of the two probes.

Wellhead natural gas is dried by passing the feed by line 3, through free water separator 4, to zeolite molecular sieve bed 1, valve 10 being open and 13 closed. 1-10% sidestream of the feed is passed by line 9, through heater 12, where it is heated to 500-700‹F. and thence downward through exhausted bed 2, thereby regenerating it, valve 14 being open and 11 closed. Dry effluent from bed 1 leaves by lines 15, 20 and 21, while wet effluent from bed 2 passes by lines 16 and 24 to cooler 25 and free water separator 23; the two effluents are then mixed in line 19 as the product gas. When bed 1 is exhausted the roles of the two beds are reversed. Suitable zeolites are types A, D, S, R, T or X having a pore size of 3-10A. In a modification (see Fig. 2, not shown), the effluents from each bed are passed in heat exchange relationship with each other, before each passes to its own free water separator, the gaseous effluent from the two separators being combined.

A photographic processing liquid for the treatment of light-sensitive silver halide materials contains as chemical fogging agent a tin (II) chelate of an amimo carboxylic acid in acid form or in the form of a water-soluble salt. The aminocarboxylic acid preferably has the formula: wherein L is alkylene including substituted alkylene, cycloalkylene including substituted cycloalkylene or alkylene interrupted by one or more hetero atoms, X represents 0, 1 or 2, R is C 1-5  alkylene including substituted C 1-5  alkylene, and each of R 1  and R 2  (the same or different) stands for hydrogen, C 1-5  alkyl including substituted C 1-5  alkyl, aralkyl including substituted aralkyl or aryl including substituted aryl. The processing liquid may be a developing liquid comprising at least one developing agent for silver halide, and the said tin (II) chelate may be added in an amount between 10mg and 10g per litre of the processing liquid. The tin (II) chelates of aminocarboxylic acids have a good fogging action to form developable specks in light-sensitive silver halide material when the latter is treated with an aqueous solution of the said tin (II) chelate and also remain stable in alkaline solutions enabling them to be incorporated in a photographic developer solution.
