Title: Improvements in and relating to striker plates for door locks
IPC: E05B63/24
Filed: 1931-11-20
Abstract: 388,500. Striking-plates for latches. PRESSED STEEL CO. OF GREAT BRITAIN, Ltd., Cowley, Oxford, and FERNBERG, E. B., 11, The Drive, Edgware, Middlesex. Nov. 20, 1931, No. 32270. [Class 44.] A spring-pressed safety catch for a door latch is mounted on the striking-plate and arranged so that when it is depressed it presents a surface continuous and flush with the main catch. The safety catch 6 is mounted in a recess 5 in the main catch 2 and is retained by lateral flanges 7 against the outward pressure of a leaf or spiral spring. The spiral spring 30 may seat in a socket 24, Fig. 7, or in a recess in the catch when the latter is made of sheet metal. The catch may be secured on the main catch by a pivot pin. The main catch 46, Fig. 12, may be formed with flanges 47 which are riveted to flanges 45 on a mounting plate 43 and the safety catch formed with end flanges which engage under a flange 45 on the plate 43 and a shoulder 48 on the main catch. Alternatively, the safety catch may engage on three sides with the flanges 45 on the plate 43. Specifications 380,951, [Group X], and 388,106 are referred to.

Title: Improvements in or relating to radio transmitters operating with independent side bands
IPC: H03C1/60
Filed: 1953-11-20
Abstract: 740,871. Radio transmitting systems. SOC. FRANCAISE RADIO-ELECTRIQUE. Nov. 20, 1953 [Nov. 20, 1952], No. 32275/53. Class 40 (5). For reducing distortion, a negative feed-back circuit, for a radio transmitter operating with independent side bands, is disposed between two points in the modulated carrier amplifying chain. In one embodiment the carrier from generator 10 is modulated by channels A, B in modulators 1, 2 respectively, the outputs of which are combined in a mixer 3. After amplification at 4 the frequency is changed at 5, the output signals being amplified at 6, frequency-changed again at 7 and finally radiated after further amplification at 8 and 9. A detector 15 is connected to the output stage and an amplifier 13, followed by a detector 14, to the output of the mixer 3. The detector outputs are applied to a comparator 16, the difference voltage being fed to amplifier 4 to modulate its gain. The circuits of stages 4, 13, 14, 15 and 16 are described, Fig. 4 (not shown). In other embodiments, the negative feedback circuit is connected across fewer stages and there may be two independent feedback circuits.

Title: Apparatus for automatically recording scores in a target type  amusement machine
IPC: A63B71/06
Filed: 1971-07-09
Abstract: 1312163 Recording scores F BELLANI 9 July 1971 [11 July 1970] 32396/71 Heading A6H  In apparatus for automatically recording the scores of players in a target type amusement machine, a random score is associated with each actual score detected and recorded for the players. As shown, an electromagnetically operated printing element 16 or 16' is associated with each target such as a goal (not illustrated) in an amusement machine. Whenever a target is struck, the corresponding element 16, 16' is energised to print a corresponding character onto a paper tape 13 in a respective column. At the same time a random printing element 16" is energised so that whichever print-wheel character (see below) is in position for printing is also printed onto the paper tape in a separate column. After each target is struck, an electromagnet 18 operates to advance the paper tape 13 and also an ink ribbon 17. A guillotine 22 is provided to sever the tape 13 at the end of a game. The random print wheel (Fig. 2) comprises a wheel 31 having print elements 31a and mounted for rotation on a forked rod 30 which may be lowered for printing by an electromagnet 29. During at least part of this movement, a toothed wheel 32 engages with stationary teeth 33 so as to rotate the print wheel 31 by way of a free wheel ratchet connection to randomly select the next character for printing. Instead of the random print wheel, the random score characters may be pre-printed on the tape.

Title: Photo-sensitive elements
IPC: G03C1/815
Filed: 1957-10-18
Abstract: 862,291. Photographic materials. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 18, 1957 [Oct. 23, 1956], No. 32548/57. Drawings to Specification. Class 98(2) A visible image is formed in photographic material by exposure to ultra-violet radiation, the sensitiser being protected from sunlight by a filter which transmits visible light to which the sensitiser is not sensitive. The filter and sensitizer may be intimately mixed but are preferably applied in separate layers. A solution of 1,1,1-triaryl acetonitrile of pararosaniline in acetic or proprionic acid and of 2 methyl-4,5,6,7- tetrachlorobenzo triazole in polyvinyl acetal or ethyl cellulose may be coated successively on a filing card and allowed to dry individually. The dye thus protected by the filter is insensitive to sunlight but develops brilliant colours on exposure through a stencil to far ultra-violet radiation. These colours are visible through the filter layer and do not fade in daylight. The unexposed dye retains its sensitivity and may be converted to the coloured form by a further ultra-violet exposure at any time.

Abstract: 925,122. Magnetic holding devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 22, 1960 [Sept. 22, 1959], No. 32585/60. Class 35. [Also in Group XXXVI] In a fluid-tight lifting electromagnet, more particularly for handling rods in a submerged atomic pile, comprising a fluidtight casing 1 containing a winding and core 11, 12 and a means which indicates whether or not the electromagnet is engaging a piece (not shown) to be lifted, the core and winding are movable, relative to the casing 1, between a position of minimum reluctance in which the magnetic circuit is completed through casing wall 2 and the end of the piece, and a position determined by a spring 14. Thus, with the winding 11 energized, the core 12 is drawn down when wall 2 contacts the head of the piece, and when the winding is de-energized, the spring 14 returns the core to the position shown. The core movement is conveyed by a rod 19 to the operating lever 20 of a microswitch 21 whose conductors 22 together with winding power-supply conductors 18 pass through a fluid-tight seal in the cover 3 of casing 1 and are enclosed by a tube 8, e.g. of polythene. The seal comprises an outer bush 7 screwed on cover 3 and holding an inner bush 5 tightly against core 4 of the cover. Bush 7 is locked by nut 9 to cover 3 which is, e.g., argon-welded to casing 1 which may be of stainless steel.

A cover flap 20 is provided. In another form, the pockets are constructed by means of a central partition arranged between two outer covers and each outer cover is provided with an inspection aperture. An extension of the central partition forms a flap covering one of the pockets, but both pockets may be closed by flaps.

Title: A continuous rolling mill and improved hot rolling process for the production of trapezoidal cross-section strip
IPC: B21B1/08
Filed: 1954-11-12
Abstract: 791,401. Rolling. COMPAGNIE GENERALE DU DURALUMIN & DU CUIVRE. Nov. 12, 1954 [Nov. 13, 1953], No. 32870/54. Class 83 (4). In a method of continuous rolling of trapezoidal cross-section bar S4, Fig. 1b, from rectangular bar M as for making commutators, guides 1, Fig. 1a, are used to constrain the bar on the entry side to the first pair of rolls and maintain the bar straight. The bar M is first rolled to the section S2 between vertical rolls 2 and then between rolls 3 having their axes inclined to the horizontal. The guide 1 on the side of the larger base of the trapezoid has a projection 15 which extends between the rolls 3. In a third stage, rolls 4 reduce the section still further and are so arranged that the bar is elongated equally across the section, and therefore remains straight. To obtain this result the points of intersection 13, 14 of the extended contact faces of the rolls 3, 4 lie on a line 8 which is parallel to the bar M. The speed of the successive rolls may also be controlled to exert a predetermined tension in the bar. A rolling mill suitable for mounting inclined rolls 27, Fig. 2, comprises side frames 21 having arcuate projections 23<SP>1</SP> between which roll supports 24 are rockable about a centre 26 for angular adjustment. Movement of the supports 24 is caused by adjustable thrust members 50 pivoted to a cross member 51 and acting against pneumatic cylinders 53 pivoted on the opposite side of the supports 24. The rolls 27 are mounted on shafts 28 in bearing members 29 which are carried by screwdowns 36 in the supports 24. Pass adjustment is obtained by operating an electric motor 38 which drives screw-down nuts 40 through shafts 39. The rolls 27 are driven through universally jointed shafts 33. Guides 56, 57 are mounted on the entry side of the rolls.
