Title: Masking of workpieces
IPC: H01J9/233
Filed: 1972-06-01
Abstract: 1389106 Etching WESTERN ELECTRIC CO Inc 1 June 1972 [7 June 1971] 25610/72 Heading B6J [Also in Division H1] A workpiece 12, Fig. 6, such as a Si wafer containing an array of photodiodes and destined to become a charge-storage target for a t.v. camera, is masked on one surface, e.g. during a selective etching process, by an apertured mask 49, e.g. of sapphire, while the opposite surface is located in contact with a liquid such as deionized water 28 in a cavity 31 of a base member 32. The base member 32 and an upper member 46, which urges the mask 49 on to the workpiece 12 when it is force-fitted or screw-threaded over the base member 32, may both be made of Teflon (Registered Trade Mark). Excess liquid initially forming a meniscus above the cavity 31 is forced out through a vent 42 when the workpiece 12 is pressed down on to the base member 32. The vent 42 is closed when the upper member 46 is applied to the base member 32. Etching apparatus in which a plurality of the assemblies 55 illustrated in Fig. 6 may be mounted simultaneously is shown in Fig. 7, the apparatus including several spur gears 57 driven from a single rotating shaft 64 and on each of which one of the assemblies 55 is mounted. The assemblies 55 thus rotate in a tank 68 containing the etchant, which is agitated by a rotating paddle. The thickness of each workpiece 12 may be monitored by measuring the absorption of I-R radiation therein. For this purpose an I-R- transparent portion 87 (Fig. 6) is provided in the base member 58.

Patent GB-257897-A (GB)
Abstract: 257,897. Kreissle, R. Sept. 5, 1925, [Convention date]. Cylinders. pipes for and ports of.-In two-stroke-cycle engines which are scavenged by air entering through ports e in the cylinder wall, a chamber g is interposed between the compressed air supply pipe f and the ports e. The size of this chamber is such that it will hold sufficient air under pressure to completely scavenge the cylinder, the pressure in the chamber at the end of the scavenging period being equal to the back pressure in the exhaust pipe. The admission passage h to the chamber may be controlled automatically or by a hand-actuated conical stop i. In small engines the crank chamber may contain the chamber g. If desired, and as shown in Fig. 2, additional cylinder ports l may be provided to admit combustion air, which will be at a higher pressure than the scavenging air; the delivery to the ports is controlled by an automatic or positively actuated valve. The additional air ports may be near the cylinder head. The Specification as open to inspection under Sect. 91 (3) (a) states that the crank case could constitute the chamber for the reception of the scavenging air. This subject-matter does not appear in the Specification as accepted.

Title: Brake pressure modulator valves in motor vehicle brake systems
IPC: B60T8/42
Filed: 1966-06-10
Abstract: 1,120,137. Anti-skid braking system. GENERAL MOTORS CORP. 10 June, 1966 [13 Aug., 1965, No. 25948/66. Heading F2F. A motor vehicle braking system comprises a master cylinder connected to the front wheel brakes 20 and to the fluid inlet of a brake pressure modulator valve 12, the rear brakes 16 are connected to the valve outlet, the modulator valve including a cut-off valve 28 controlling communication between the inlet and outlet and acted upon by a servomotor 32, high and low pressure ports 58, 22 being connected to opposite sides of the servomotor by a movable valve element 50 in a rest position thereof, a skid sensor is connected to supply a signal input at 24 when skidding occurs to move the valve element to reverse the connections to the servomotor which permits movement of the cut off valve into a position interrupting communication between the fluid inlet and outlet. Fig. 2 shows the modulator valve in its normal position, servomotor chamber 36 being connected by passages 62, 60, 40 to a vacuum source and chamber 34 to atmosphere by passages 64, 54, 56 and filter 58. The low pressure connection at 22 acts also on the left side of diaphragm 46 to maintain the valve element 50 in its appropriate leftwards position. The servomotor then maintains cut off valve 28 in an open position whereby on actuation of the master cylinder fluid can flow through inlet 10 and outlet 14 to the rear brakes. When the skid sensor operates to deliver a signal at 24 in the form of a pressure pulse valve element 50 moves rightwards to reverse the servomotor pressure connections, the member 30 moving rightwards to allow valve 28 to seat and interrupt communication with the rear brakes. The movement of member 30 also increases the volume of the rear brake line. On cessation of the signal the valve parts revert to their previous positions. The signal input from the sensor, by the path 24, may be a sub- or super-atmospheric pulse or the path may be a mechanical link. In another embodiment the valve is modified to accept a source of super-atmospheric pressure in place of the vacuum source.

Abstract: 1308741 Tool turrets; indexing INDEX-WERKE KG HAHN & TESSKY 19 April 1971 [3 March 1971] 26628/71 Headings B3B and B3T An indexible tool turret 1, e.g. for a turret lathe is provided with locking teeth 41 and is axially movable to engage and disengage the teeth 41 and to allow a drive mechanism to rotate the turret when in the disengaged position to a predetermined working position, whereupon the turret may be retracted and finally clamped tightly in its indexed position. The drive mechanism is arranged to perform the final stage of the indexing movement at reduced speed. The turret spindle 20 carries a member 40 which forms part of a claw clutch 38 which is disengaged when the turret is clamped in its working position, i.e. when axially retracted but alternatively (when the turret is axially advanced) forms a drive connection to the turret from a worm and worm-wheel drive 26, 44. The turret is biased by springs 35 towards the unlocked position and axial movement thereof is basically caused by the co-operation of cam faces on claws 32, 33, the latter being fixed and the former arranged on the front face of a rotatable nut member 30. Rotation of the nut 30 also serves to apply a clamping force to the turret when the locking teeth 41 are engaged by reason of the threaded engagement of the nut with a threaded bush 48 mounted on the spindle 20. A control drum 39 integral with the worm-wheel 44 carries a series of cams engageable with switches 45 and an end position indicating plunger 42 co-operates with a switch 43 the switches being suitably arranged for numerical control of the machine tool to ensure that the turret rotates in the shortest direction to and is stopped at a required working position. A rotary hydraulic control valve 46 carried at the end of the shaft 20 is brought into operation by the electrohydraulic control circuitry only as the required working position is approached to check the speed of an hydraulic motor driving the indexing mechanism, intermediate positions of the turret being passed without any reduction in speed.

The invention of the parent Specification is modified in that a linkage 90, 92, Fig. 1, ineluding a rotatable control member 91 mounted co-axially with a .pivot of the pantograph, connects the tool-holder 34 either with the toolposition indicator (63, Fig. 8, not shown) or with the tracer 80. In the latter case, the tracer, which is formed with a slightly greater angle than the tool to prevent the flanks of the latter from contacting the grinding wheel, is secured to a crank arm 82, Fig. 4, extending from the disc 58 and carries a forked member 83 to receive a part-spherical portion 85 carried by a crank arm 87. The latter is secured to a spindle 65 at an angle of 90 degrees to a second crank arm 89 connecting the spindle with the linkage 90, 92. A handle 94 enables the tracer or indicator and the tool-holder to be turned in unison between the limits determined by stops 96 on the arm 11 and a pin 95 on the member 91. Bodily movement of the tracer is effected by a knob 98 freely mounted on the spindle 65 or at a lower position on the arm 42a. A turnbuckle or the like 97 enables the positions of the tool and tracer to be accurately matched. The arrangement of the coupling 83, 85 may be reversed. The diamond or other tool 37, Fig. 6, is secured in a recess in a locating block 36 by a screw 100 passing through its shank and acting to contract the recess. The block 36 is slidable upon dovetail or other ways in the holder 34. The tool is given a slight rake with respect to the grinding wheel.
