Heading B3H. A crank-shaft forging apparatus comprises a pair of cradles 3, 3<SP>1</SP> adapted to move horizontally on a slide by the interaction of inclined slideways 7 to upset the blank 8 and upper and lower crank-pin dies 10, 11 to offset the upset portion, the upper die being mounted on a piston 13a in an hydraulic cylinder 13 which is connected to a reservoir through a discharge valve to allow initial simultaneous upsetting and offsetting and a final upsetting in which the crank-shaft webs are formed. The valve (not shown) is preset as a function of the blank size to cause the downward movement of the upper die 10 to stop after the offsetting. Alternatively the cylinder may have a pair of discharge valves to permit initial upsetting, intermediate simultaneous upsetting and offsetting and final upsetting. The cradles 3, 3<SP>1</SP> carry blank holding blocks 14-17 with flat faces adjacent the dies 10, 11 whose faces are recessed, 20, 22, to define limits for the crank-web size. Alternatively, Figs. 5, 7 and 8 (not shown), the faces of the blocks and/or the die may be recessed. The lower crank-pin die 11 is also mounted on a piston 12a of an hydraulic cylinder 12 which holds the die in position until a pre-set pressure. Auxiliary hydraulic actuators 18, 18<SP>1</SP> also serve to move the cradles 3, 3<SP>1</SP>. The lower assembly of the apparatus can be removed from the press bed 1 for loading with a blank. In an alternative embodiment, Fig. 10, the cradles 43, 43<SP>1</SP> are slidable on slideways 44, 44<SP>1</SP> and carry lower dies 54, 56 which co-operate with upper dies 55, 57 carried by die blocks 63, 63<SP>1</SP>.

Abstract: 1,229,876. Cutting by fusion. LASER TECHNIQUE SA. 17 Sept., 1968 [25 Sept., 1967], No. 44022/68. Heading B3V. [Also in Division H1] A bore is formed in a workpiece, particularly a watch jewel, by locating the workpiece at the focus of a laser having a focused optical system, and applying a train of laser pulses each directed to a different spaced point about the axis of the bore to be formed. The workpiece may be moved relatively to the laser system, or as shown in Fig. 1 the axis 9a of the emergent laser beam may be offset by a tilted glass disc 11 from the bore axis 9 of a fixed workpiece 21, and be rotated about that axis. The laser beam is focused on to the workpiece by an axially displaceable lens 8, the lens being mounted in an inner tube 5 slidable with respect to an outer tube 1. Successive laser pulses are directed at points spaced about the bore axis by rotating the outer tube, a drive (not shown) engaging a gear-wheel 3 attached to the tube 1. A cam 4, also mounted on the outer tube, controls the emission of laser pulses. Adjustable displacement of the axis 9a from the bore axis 9 is effected by rotating a screwed cap 12 which alters the tilt of the glass disc 11, rotation of the disc within the tube being prevented by a spring- loaded plunger 15 which engages a notch 19 in the disc. In a modification, Fig. 3, the angle of the light incident on the workpiece may be varied by the combined use of a rotatable refracting block 33 and a lens 8 displaceable in a plane normal to the optical axis by one or more adjusting screws 29. The lens is mounted on a frame 25 adjacent to a sapphire window 27 and is urged by a spring 28 against the adjusting screw. A bore may be formed by a plurality of complete rotations of the tube 1 with those pulses applied during the second rotation aimed at points intermediate the points acted upon during the first rotation. An example is given of a 9-step cam controlling the laser through a divide-by-two frequency divider, the laser in its first rotation acting on four points equally spaced about the axis 9, and acting in points intermediate the first points during its second rotation. The focus may be adjusted in the axial direction during boring of bores of substantial depth with automatic control effected by a cam disc.

Abstract: 1,258,377. Testing lamps. AGFA-GEVAERT A.G. Feb.20, 1970 [Feb.21, 1969], No.8210/70. Heading G1U. [Also in Divisions G2 and G3] Photographic flash apparatus includes a switching device, as shown on transistor 2, which can assume a switched state in accordance with the magnitude of a voltage applied to its input, and indicator means, as shown on lamp 3, for indicating the switched state of the transistor 2, the apparatus being arranged so that, in operation, the lamp 3 provides a visual indication of the flashreadiness of a flash-bulb 11 connected to terminals 12, 13 when they are connected to the transistor input by way of a dropping resistor 10. The apparatus may form part of a photographic camera. The circuit shown also includes means for indicating inadequate lighting conditions and the condition of the power source 1 of the apparatus. To test an inserted flash-bulb 11, when there is adequate light, a photo-resistor 8 is shaded. If the bulb 11 is defective, when switch 4 is closed the indicator lamp 3 will light up. To test the battery, a changeover switch 6, 7 and a testing switch 15 are actuated. The resistances of resistors 5, 9 are of such magnitude that, until the battery voltage falls below a prescribed minimum value, the lamp 3 lights up. If there is inadequate light and no flash-bulb 11 present, the indicator lamp 3 will light up due to the high resistance of the photo-resistor 8. Insertion of a good flash-bulb will cause the lamp 3 to go out. The lamp 3 comes on again when the flash-bulb 11 is ignited and remains on until a new flashbulb has been inserted or the flash-cube rotated. In another embodiment Fig.2 (not shown), a camera has exposure control means including means for indicating flash readiness and for indicating the adequacy of the lighting conditions. A photoresistor (24) and a capacitor (25) control the exposure period. A third embodiment, Fig. 3 (not shown) is similar to that of Fig.1, but includes a capacitor (40) for actuation simultaneously with the synchro-switch. The capacitor causes a time delay in current reaching the lamp (3), an advantage if the battery (1) has a reduced output.

Abstract: 1,259,209. Digital electric computer. ING. C. OLIVETTI & C. S.p.A. 6 Nov., 1969 [11 Nov., 1968], No. 54511/69. Heading G4A. The invention relates to an electronic computer having two memories one of which is a loop of magnetic tape carrying a continuous information track. The computer described in Specification 1,259,210 has an auxiliary data and program memory in the form of a cartridge containing a loop of magnetic tape. The tape 131 has seven information tracks and an address track, 131 each track containing 40 block locations 135 with addresses 0 to 39 with addresses 20-39 interlaced with address 0-19 i.e. 0, 20, 1, 21, ..., 19, 39, 0. A block is addressed from register 99 which has six bit locations holding the tens and units digits of the address, and two bit locations defining which of four tracks are to be addressed. A flip-flop 145 is used if the other three tracks are required. Because of inertia in the tape drive system the register holds an address one below the required address and the tape address and modified address are compared. When agreement occurs the tape drive is stopped and the tape stops short of the required address. The address register is incremented by 1 and the tape is moved to the correct address. Because of the time required to find an address a search request should be inserted in a program before the block is required. Twelve registers in the recirculating memory are divided into three zones each of four registers and transfers are made on a block-byblock, zone-by-zone basis. If only a portion of a zone is to be recorded in a block it has a special "end of record" instruction. If several blocks are to be transferred without requiring separate search instructions the blocks should be adjacent with a transfer instruction incrementing the address register by 1 on each transfer. The tracks may be addressed by indirect addressing to permit branching operations.
