Abstract: 1503728 Selective printing COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII-HONEYWELL BULL 25 Nov 1975 [11 Dec 1974] 48446/75 Heading B6F In a printer receiving a type band cartridge comprising an endless band 1 having type bearing fingers, which band passes around two pulleys (2, 3, Figs. 1, 3, not shown) the distance between which is adjustable for tensioning the band when the cartridge is inserted into the printer, the cartridge further comprising type finger protecting means 50, means are provided on the printer to prevent misuse of the cartridge, such means comprising locking means 301-304 which prevent operation of band tensioning means until the cartridge is mounted on the printer. The band is tensioned by increasing the separation of the pulleys (2, 3) by means of a detachable tool (200, Figs. 4, 6, not shown) whereby a cam 114 can be rotated. Insertion of the tool is prevented by a plate 303 which rests in blocking position in a slot 118 until removed by a plunger 301 on insertion of the cartridge into the printer. The tool includes a cam surface (203, Fig. 6) which lifts the type finger protecting means 50 when the tool is inserted into the cartridge. Rotation of the tool firstly urges the pulleys apart to bring them into contact with the band 1, which is held by a magnetic strip 27 against the cartridge casing until such initial movement, through a spring 106. The final rotation of the tool compresses the spring 106 and applies tension to the band 1. On tensioning the band, the tool is removed, whereby the type finger protecting means 50 returns to its lower position, and a cover 29 can be hinged back, whereby the plate 303 re-enters slot 118 to block insertion of the tool until the cover is returned.

Title: Apparatus for firing guns by means of strikers
IPC: F41A19/59
Filed: 1964-12-01
Abstract: 1,047,077. Firing mechanisms. RHEINMETALL G.m.b.H. Dec. 1, 1964 [Dec. 12, 1963], No. 48800/64. Heading F3C. Apparatus for firing guns comprises in combination a breech block 1 in which is mounted an energizing coil 6 and a movable armature 4, a striker 3 and means to operate the striker either electromagnetically or mechanically. The striker 3 is biased to the position shown by a return spring 14 interposed between a washer 16 on the striker and a sleeve 10 partly surrounding the armature and held against a shoulder 11 by a spring 12. Actuation of a firing button causes a current to flow in coil 6 which draws the armature 4 into the coil and the tip 23 of the striker fires the primer of a shell. Mechanical actuation of the striker is effected by pulling a lanyard 27 fixed to a knob 36 on a lever 26. The latter is rigid with a spindle 25 which is formed with a cam that engages a lug on the armature when the spindle is rotated to first draw the armature back compressing spring 12 and then releasing it to cause the kinetic energy of the armature and striker to project the tip of the striker through the opening 24. Spring 14 returning the armature and striker to the position shown. The firing spindle 25 and the lever 26 are returned to their original position by a spring-loaded plunger engaging a shoulder on the spindle. A safety device is provided by a spring-loaded locking pin 37 which is permitted to engage in a hole when the lanyard is removed and the lever 26 is pivoted through a small angle. This movement causes the spindle 25 to rotate so that the cam thereon engages the lug on the armature to slightly draw it back and prevent even electromagnetic firing. At the same time the end 34 of the spring-loaded plunger returning the spindle to its original position projects out of its bore to prevent the handle 2 being moved to open the breech.

Abstract: 1,194,600. Sintered tungsten or molybdenum base alloys. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. Oct.25, 1968 [Nov.3, 1967], No.50181/67. Headings C7A, C7D and C7U. A metal body consisting mainly of W and/or Mo, is composed of, or has at least a surface layer composed of, an alloy comprising:- at least # Al, Be, Ce, Cr, Hf, # 5-20% in total one of # Mg, Th, Ti, U, Zr, # 5-20% in total, at least # Co, Ir, Ni, Os, # 0À01-10% in total, one of #Pd, Pt, Rh, Ru # and at # As, Bi, Ge, P, S, # least # 0À001-10% in total, of # Sb, Se, Si, Sn, Te the balance being W and/or Mo in any relative proportions. The relative proportions of elements from the three groups are so chosen that the body can be made resistant to high temperature oxidation by heating in air or moist hydrogen to form an adherent protective oxide layer. A preferred alloy comprises Cr 5-20%, Pd, 0À5-10% and As 0À01-1%, the balance being W and/or Mo. If the body is to be of one basic composition it may be made by arc melting and casting or preferably by mixing the constituents, some of which may be present as master alloys, in powder form, preferably with a particle size smaller than 5 microns, isostatically pressing (e.g. in glycerol) and then sintering. If the sintering temperature is high enough to form the required oxide layer, it may be performed in air or moist hydrogen. If this is not so the sintered compact must be heat treated in air or moist hydrogen as is the case for the cast bodies. For a body which only has the surface layer of the appropriate composition, a body of a W and/or Mo based alloy, optionally containing Re, Ta, ThO 2  and potassium silicate, is coated with the elements in which it is deficient (e.g. by vapour deposition or electro-plating) and is subjected to a diffusing heat treatment prior to the oxidizing heat treatment in air or moist hydrogen. Some compositions do not require a separate heat treatment as the oxide layer is formed when the article is used.

Title: Control apparatus for a vehcle braking system
IPC: B60T8/36
Filed: 1973-10-30
Abstract: 1441974 Anti-skid brake control apparatus AISIN SEIKI KK 30 Oct 1973 [31 Oct 1972] 50368/73 Heading F2F A first valve in a flow path between a master cylinder 27 and wheel cylinders 33 is actuated by an assembly controlled by fluid pressure of an accumulator ACC-2 whereby a fall in pressure from the accumulator is detected to operate a second valve C to connect a reserve accumulator ACC-1 to the valve actuating assembly. Fluid from the accumulator ACC-2 passes via passages 66, 73 and 85 in a changeover valve and passages 63, 62, a valve 54, 55 kept open by pressure from the accumulator ACC-2 to a chamber 50, and a passage 59 to a chamber 23 actuating a piston 17 and a stem 12 of the assembly to keep a ball valve member 8 from a seating 11 of the first valve to allow fluid flow to front wheel cylinders 33, as well as rear wheel cylinders (not shown) which are fed directly from the master cylinder 27. Upon wheel lock, a solenoid operated valve spool 74 of the changeover valve is moved so that the passage 73 is connected to a reservoir R. According to the signal, a second spool 74<SP>1</SP> is operated to allow fluid flow through either of ports 86, 87 of different area from the inlet 85 to the passage 73 thus providing different flow rates from the chamber 23 to the reservoir R for different closing speeds of the first valve 8, 11. Upon failure of the accumulator ACC-2, a piston 48 moves rightwardly under the action of a spring 95 to close the valve 54, 55 to stop fluid flow to or from the chamber 23 and to open a ball valve 43, 43<SP>1</SP> similar to the first valve to allow fluid flow therethrough between the master cylinder 27 and the front wheel cylinders 33. If, at the time, the chamber 23 is connected to the reservoir R, the stem 12 is moved to the left which closes the first valve 8, 11 (although fluid will pass through the valve 43, 43<SP>1</SP>) and causes an increase in volume and consequential decrease in pressure for a given master cylinder pedal stroke. To avoid this, a pressure sensing switch S, or other detector, associated with the accumulator ACC-2 operates a solenoid valve C to connect the chamber 23 with the reserve accumulator ACC-1.

Some of the discs 2 are provided with a protrusion 10 which is received in a groove 11 in the cylinder 1. The discs 2 are separated by discs 14 which also have protrusions received in the groove 11. The reset member 12 is located in the keyhole 8. When the key 7 is turned it engages a protrusion 13 of each disc 2 and, in order to allow removal of the key, every disc 2 must be returned to the keyremoving position. This is effected by transmitting torque through the clutch 15 to the reset member 12, surfaces 24 or 25 of the latter, depending on the direction of rotation, engaging the protrusions 13 of the discs 2. The cylinder 1 is locked to the housing 3 by a bar 4 and the cylinder is unlocked from the housing when recesses 9, 9 in the discs 2 are moved into alignment with the bar 4. The key has two combination surfaces for each disc 2, each surface acting according to the direction of rotation of the key. The discs 14 have a smaller central opening than the discs 2 to prevent the latter engaging the reset member 12. The clutch 15 comprises balls 17 which are urged, by a spring 16 into recesses 18 in the reset member 12, In modification the clutch acts in the radial direction and the reset member is located about the periphery of the locking discs, and the reset member is located between the keyhole and radial surfaces of the discs 2.
