Title: System for preventing collision of vehicles
Inventor: AOKI MASOA
IPC: G01S17/18
Filed: 1970-10-14
Abstract: 1300299 Laser radar MITSUBISHI DENKI KK 14 Oct 1970 48893/70 Heading H4D A pulsed laser radar is carried by a motor vehicle and is used to detect the distance to an obstacle and cause automatic actuation of the braking system if the distance is too small in relation to the vehicle's speed. The return from a transmitted pulse is gated to the detector by a gate pulse delayed from the transmitted pulse by a period proportional to the vehicle's speed. Three gates may be used each delayed by successively greater amounts and giving corresponding warnings of decreasing danger when an obstacle reflection is gated therethrough. In the single gate embodiment, Figs. 1, 3, an astable multivibrator triggering generator 10 feeds pulses (a) Fig. 3, to a thyrister/capacitor pulser 12 which causes a laser diode to emit pulses (b) of coherent light towards the obstacle. The reflections (c) are detected by photo transistors 20 and the video signal fed, after amplifying, to gate 28. The gating generator 24 produces gating pulses (d) delayed under the control of the output of a vehicle speed detector 26. When the obstacle is at a dangerous distance commensurate with the vehicles speed, its reflection is gated by 28 (e) and fed to an F.E.T./diode/ capacitor pulse height holding circuit 30, reset by each trigger pulse by a discharge generator 32, to give an output (f) successively recording the heights of the gated reflections. An integrator 34 smoothes the height output and actuates an alarm 36 and the braking system, when its output rises to indicate an actual obstacle rather than just noise. In the three gate embodiment (Fig. 4, not shown), the three alarms are green, orange and red lights respectively. The invention is stated to be applicable to radio and acoustic energy.

Abstract: 1498719 Printed circuit test apparatus INTERNATIONAL BUSINESS MACHINES CORP 2 Dec 1975 [30 Dec 1974] 49365/75 Heading G1U [Also in Division H2] An apparatus for testing the continuity of various electrical paths extending between pairs of terminals on a device under test, such as a wafer carrying a plurality of inter-connected terminals for the subsequent mounting of semi-conductor chips, includes a plurality of probes that can be brought into contact with the terminals, means whereby a particular potential ('up' or 'down') can be applied to a first selected terminal, and means whereby the resulting potential of a second selected terminal can be examined to determine whether a conductive path exists between the two selected terminals. Thus each probe 19, Fig. 3, is associated with both a potential applying circuit - referred to as a "forcing circuit" - and a potential sensing circuit, and particular ones of these circuits are selectable in a co-ordinate manner. As shown probe 2 of probes 19 is associated with a forcing circuit comprising transistors T 1 to T5, and a sensing circuit comprising transistors T6 to T9, and similarly for probe 32. If for example, the forcing circuit of probe 2 is selected - by up potentials FX2, FY1 - and if the sense circuit of probe 32 is selected - by down potentials SX16, SY2, then the common output across R7 for all the sense circuits will be down if a conductive path exists between probes 2 and 32, and up otherwise. (This follows immediately by noting that the non-selected sense circuit must have at least one up potential SX2 or SY1, and the non-selected force circuit at least one down potential FX16 or FY2).

Title: Improvements in indexing turret heads
Inventor: DICKSON DONALD JOHN
IPC: B23Q16/06
Filed: 1964-12-14
Abstract: 1,127,018. Lathe details. DICKSONS (ENG.) Ltd. 14 Dec., 1965 [14 Dec., 1964], No. 50898/64. Heading B3T. An indexable turret-head may be clamped in any position or in one of four particular positions by a handle 9, initial and continued movements of which in one direction respectively unclamp and index the turret body 1 while return movement of the handle to its initial position clamps the turret body in its new position. A central rotatable spindle 7 which receives rotary motion from the handle 9 via a cap 8 splined to the spindle 7, is threaded both to a stationary spigot 2 around which the turret body may be indexed and to a clamping bush 11, the action of the threaded portions being such that on suitably directed rotation pressure is exerted on the clamping bush 11 and through needle bearings 11a to a bush 22 fixed to the turret body 1 to clamp the latter to a base-plate, not shown. The turret body 1 is additionally locked in any of four index positions by a spring-pressed pin 5 which engages corresponding holes 4 in a flange of the spigot 2. The spindle 7 has, splined thereto, a pawl ring 12 with upper and lower pawls 14, 13. The lower pawl acts to rotate a cam ring 15 which by means of a roller follower 18 and actuating member 19 lifts the pin 5, during the initial movement of the handle, out of the hole 4. Upper pawl 14 then engages the bush 22 to index the turret body 1. After 90 degrees rotation of the turret body 1 the roller follower 18 drops into a fresh slot in the cam ring 15 allowing the pin 5 to enter a fresh hole. Handle 9 is then returned to its initial position. Rotary movement of spindle 7 and the handle 9 are limited by a stop member 10, e.g. to 120 degrees.

Title: Apparatus for gripping workpieces which are to be fed or pushed into a forming tool
IPC: B21C5/00
Filed: 1970-10-29
Abstract: 1330138 Drawing TH KIESERLING & ALBRECHT 29 Oct 1970 [22 Jan 1970] 51481/70 Heading B3P An apparatus for feeding a workpiece into a forming tool such as a drawing die comprises workpiece gripping jaws 9, each having a wedge surface resting against a wedge surface 7b of an adjusting wedge 16, 16a movable relative to a feeding slide 1 by a threaded spindle 18, 18b, the slide 1 having at least one abutment 26 for engaging an adjusting wedge 16a during the feeding operation. The taper of the wedge surface 17b of each adjusting wedge 16, 16a is less steep than the taper of a second wedge surface of the adjusting wedge in engagement with the slide 1 to facilitate frictional locking to the workpiece. In the embodiment described, three workpieces (6, 7, 8) (Fig. 1, not shown) are each gripped by a pair of jaws in the slide 1. Each gripping jaw 9 is provided with a detachable member 12 and is slidable on the adjusting wedge 16, 16a. Each wedge 16, 16a is connected to one end of a piston-rod 24 attached to a piston 23 which is enclosed in a cylinder 22 connected by a lug 22a to the respective gripping jaw 9. When a valve (28) (Fig. 3, not shown) is actuated, hydraulic fluid is passed through bores 24b in the piston-rods 24 causing the cylinders 22 to move and the gripping jaws 9 to grip the workpieces. Fluid is also introduced, via non-return valves (27), into cylinders 25 positioned in the slide 1 so that pistons 26 are pressed against the spindles 18b to prevent movement of the upper adjusting wedges 16a. The slide 1 is then moved by a piston and cylinder 2, 3 to push the workpieces into the drawing die. When the valve (28) is again moved, the pistons 26 are retracted allowing the upper wedges 16a to move a small distance X and the gripping jaws 9 to open. The pressure of the fluid in the circuit is adjustable.

Abstract: 1,161,516. Change speed control. LINDE A.G. 18 Nov., 1966 [19 Nov., 1965], No. 51767/66. Heading F2D. A conjoint control for an I.C. engine 1 and a variable displacement pump 2 of a hydrostatic transmission driven thereby comprises a pedal 45 having an arm 37 pivoted to a double lever 35, one end of which is biased by a spring 46 and carries a linkage 38-41 acting on a speed control lever of the engine, and the other end of which is biased by a spring 33 and is connected through an hydraulic linkage 19-32 to an servo-system 4-17 acting on on the adjusting element 3 of the pump 2, the moment of spring 46 about the fulcrum point 36 of lever 35 being greater than that of spring 33 so that, on initial depression of pedal 45, the pump is adjusted first, and then the engine. On depressing pedal 45, with valve 26 in either a forward or reverse drive position, the fulcrum point of lever 35 is moved and, due to the springs 33, 46, the piston 32 is moved to charge one of two chambers 22, 23 in cylinder 20 to move a push rod 18 to position the spool of a valve 12 which allows an auxiliary pump 15 to charge either of chambers 8, 9, to move a cylinder 4 fast with the adjusting element 3 of the pump 2. The cylinder 4 is linked at 13 to the body of the valve 12 which follows up. When the pump 2 has been positioned, the spring 33 and hydraulic pressure exert a greater moment on lever 35 than spring 46, and the linkage for the engine adjusting element then moves to adjust the engine. Rotation of a manual lever 52 positions the valve 26 in its forward or reverse end position. Further rotation of the lever past either of these positions has on effect on the valve 26 but acts through stops 54 on the push rod 18 directly on the valve 12 to adjust the pump independently of the pedal 45. A manual lever 51 allows setting of the engine at a higher power setting independently of the position of pedal 45 when desired e.g. for driving additional pumps for hydraulic hoists. Joints 47, 50 in the engine control linkage transmit compression forces only, thus preventing setting of the engine at a lower power setting than that corresponding to the depression of pedal 45, and preventing the setting of the lever 51 from influencing the position of lever 35.

Abstract: 1,249,887. Selective signalling. GENERAL ELECTRIC CO. 4 Nov., 1968 [20 Dec., 1967], No. 52253/68. Heading G4H. [Also in Division H3] A circuit responsive to two sequentially transmitted frequencies comprises first and second frequency responsive circuits 1, 2 (tuned reeds) and a switch 22 which inactivates the circuit 2 except for a period following receipt of the first frequency and determined by circuit 26, 27. Receipt of the first frequency causes reed 11 to charge capacitors 13, 16, switch 15 being biased off by capacitor 13 as charge builds up. As capacitor 16 is charged, switch 30 is turned on to discharge capacitor 27 previously charged via 26, but bias switch 31 is also turned on to maintain-switch 22 off. At the end of the first frequency, 13 discharges rapidly through 18, turning switch 15 on to discharge 16, and subsequently switches 30 and 31 are turned off. Switch 22 turns on so that receipt of the second frequency causes reed 21 to charge capacitor 23, but when capacitor 27 has charged via 26, switch 22 is again turned off. Additional reeds may be provided to allow selection of a group of receivers by a common two frequency signal, receipt of the first station or group frequency inhibiting the supply to the second group or station-frequency circuit respectively, Fig. 2 (not shown).
