Patent GB-1105624-A (GB)
Title: Improvements in or relating to electronic memories
IPC: G11C11/40
Filed: 1965-04-05
Abstract: 1,105,624. Gating circuits. COMPAGNIE DES FREINS ET SIGNAUX WESTING- HOUSE. 5 April, 1965 [3 April, 1964], No. 14434/65. Heading H3T. A fail-safe switching circuit comprises a transistor having a repetitive signal as input, and a feedback path from output to input comprising a rectifier, resistor and capacitor to integrate the feedback signal and hold the transistor conducting as long as the repetitive signal appears at the output. In Fig. 1, transistor 1 acts as an AND gate with three inputs. In the absence of an input to transistor 25, the transistor 1 is either cut off or saturated according to the state of switch 9 (in practice a source of trigger pulses). Oscillations applied to transistor 25 are rectified by diode-capacitor circuit 20, 21 and, if switch 9 is open, will bias the base of transistor 1 to an intermediate state of conduction when the oscillations will appear on the collector output line. The integrating feedback circuit will maintain this state and the oscillations will pass, gated by the switch 9. Any component failure will suppress the oscillations at the output. In a modification (Fig. 3, not shown) a further transistor (49) is inserted in the feedback path to act as an OR gate as in Specification 1,095,071, with the trigger input applied via another transistor (63) to the base of the further transistor (49). In another version (Fig. 4, not shown) the further transistor (70) acts as an AND gate in the feedback path (see Specification 1,099,001), receiving the oscillations and the integrated feedback voltage, the trigger pulses being applied directly to the output transistor as in Fig. 1.

Title: Apparatus for the hardening of glass
IPC: C03B27/052
Filed: 1932-05-21
Abstract: 385,843. Hardening glass. COMPAGNIES REUNIES DES GLACES ET VERRES SPECIAUX DU NORD DE LA FRANCE, Boussois-sur-Sambre, Nord, France. May 21, 1932, No. 14516. Convention date, Sept. 2, 1931. [Class 56.] Relates to apparatus for hardening sheets of glass by means of air jets directed on to the surfaces of the glass while it is hot, the jets being kept in motion while the glass is cooling in order to obtain uniformity of hardening. According to the invention, the jets are moved with a circular movement of small amplitude in planes parallel to the surfaces of the sheet. The air jets may proceed from small holes formed in a casing or in a grid G made up of pipes which are supported by supply pipes 1. A yoke 5, to which the upper end of each pipe 1 is secured, forms the strap of an eccentric sheave which is bolted to the end of a shaft 8. The lower end of the tube 1 is pivoted to a crank 18 on the end of a shaft 19, and the shafts 8, 19 are rotated in unison with one another by a motor 20. Two of such devices are used, as shown, and the sheet 27 of glass to be hardened is inserted between them. The rotation of the shafts 8, 19 causes the grids G to move with a circular motion, and the jets of air move over the surfaces of the glass. The support 29 from which the sheet of glass is suspended is counterbalanced by suitable weights.

Title: Improvement in shuttle stop motions for looms for weaving
IPC: D03D51/00
Filed: 1932-05-23
Abstract: 396,518. Loom-shuttle stop-motions. CAMPS, J. P., 80, Colomer Street, Sabadell, Spain. May 23, 1932, No. 14547. [Class 142 (i).] When the crank 18 is in its highest position, the tail 16 of a lever 8 pivoted on the lay is engaged by a roller 15 carried by a spring-controlled lever 11 mounted on the frame. The lever 8 is thereby urged in a clockwise direction and a roller 20 mounted thereon is pressed against a lever 21 acting on the swell 2. If the shuttle 3 is not properly boxed, the lever 8 is allowed to turn, and a dagger 9 carried therewith moves into position to engage the frog or stop 10. The lever 8 is adapted to rock in unison with a similar lever on the other side of the loom, the levers being connected by a shaft having cranks 6 carrying rollers 7 engaging in ledges on the levers. A stop 25 retains the lever 11 when the lay moves to the left of the position shown, so that the shuttle is freed from the pressure of the swell when entering or leaving the box.

Title: Improvements in or relating to fine-edged blades, tools and the like
IPC: C23C8/04
Filed: 1931-05-18
Abstract: 378,543. Alloys ; hardening. FROST, T. H., 116, Riverway, Boston, U.S.A. May 18, 1931, No. 14628. Convention date, May 24, 1930. [Classes 72 and 82 (i).] Fine-edged blades for use in safety razors, pocketknives, surgeons' knives, cutlery, and edged tools, are made by treating an aluminium steel which may contain chromium or molybdenum, or tungsten, and which can be hardened by nitrogenizing with ammonia gas at a high temperature. Warping is prevented by protecting certain areas, such as 8, against the action of the gas. The alloy known as "Nitralloy" is preferred. The treated blade is given a final grinding. The preferred method of protection against the nitrogenizing action is to coat the metal with a paste of stannic oxide in water or glycerine. Alloys containing specified proportions of carbon, manganese, silicon, aluminium, chromium, sulphur, phosphorus, molybdenum, and iron are referred to.

Title: Dimension gauge
IPC: G01B5/08
Filed: 1931-05-19
Abstract: 378,550. Lineardimension gauges. ALDEBORGH, E. H., 136, South Hamilton Street, Poughkeepsie, New York, U.S.A. May 19, 1931, No. 14786. [Class 106 (ii).] An internal gauge comprises a base member provided with a dial indicator combined with means for holding and self aligning pieces of work independently of the gauging means. A casing 10 is formed with a base 11 and an inclined top 12 which receives the stem 20 of a dial indicator 21 held by a thumb-screw 22 and split collar 23. A transverse cam shaft 25 extends through one or both sides of the casing and is provided outside the casing with a finger lever 26. The operating unit comprises a block 30 with a transverse slot 31 communicating with a slot 32 in the front face. Within the slot 31 is pivoted on centres 35 a gauging bar 33. Mounted in the slot 32 is a slide 37 provided with a projecting arm 38 having a downwardly projecting knife-edge 39, the slide being adjusted by a screw 40 and knurled head 43. The upper face of the block 30 is cut back to accommodate a slide 52 moving in guides over balls 51 and normally retained raised by two spring plungers 55 and by a spring 56 secured at one end to the slide and after passing through a bar 69 secured at the other end to a pin 59 resting on the bar. The slide 52 is integral with a work-locating arm 61 provided with knife-edges which cooperate with the knife-edge 39 to provide a three-edge adjustable work support. The arm 61 and slide 52 have a central opening in which swings the gauge arm 33 with contact 64 giving a true diametrical measurement between the contact 64 and knife-edge 39. In use, a master gauge is placed on the work supports and the arm 38 adjusted by the screw 40 to provide the proper tension of the arm 61 and the dial indicator is set for the desired reading. The finger lever 26 is then depressed. This rocks the shaft 25 and causes a cam to move the lever 33 withdrawing contact 64 within the arm 61 and by means for moving the part 75 the upper end of which engages the top edge of the slide 52 to move the arm 61 closer to the arm 38. The gauge is then removed and the work substituted, the finger being released to allow the arm 61 to rise and align the work. On sliding the latter further over the arms the contact 64 is depressed and the rear end of the arm 33 being in contact with the plunger 24 will operate the indicator. The arms 61, 38 may be reversed, the work resting on the arm 38.

Removable copper or like backing blocks i are placed in the two angles formed by each flange plate and the web plate, the blocks being chamfered or otherwise shaped at k to correspond with the shape of the fillets n. In a modification the upper edge f of the web plate may be disposed between the adjacent edges d, e, of the flange plates. The blocks i may be of the same length as the plates or may comprise short blocks moved along the joint during welding, which may be effected by the electric arc. The flange plates may be set up slightly during assembly so that when the fillets n contract the flanges are at right angles to the web.
