The plate 12 is formed of three circular members 20, 21, 22, Fig. 2 bonded together, which members have a central opening 27 and concentric rows of holes 23, 24, 25, the two latter only opening through the member 20 ; the intermediate member 21 embodies a circle of openings 26 that interconnect the holes 24, 25. Some of these holes and openings may be of a single annular construction. The discharge valve 13, Fig. 3, consists of a flat spring-steel disc embodying an annular portion 34 and a deflecting part 35 of S-shape, as shown, or of a radial spoke construction. Movement of this valve is determined by the distance between the means 15, Fig. 1, and the plate 12. The suction valve 14, Fig. 4, which is similar to the valve 13 having an annular portion 40 and a deflecting part 41, also incorporates peripheral protuberances 43, which, upon opening of the valve abut a shoulder 5 in the cylinder wall and so limit the valve movement. The means 15, Fig. 1, is of the configuration shown and is provided with two concentric rows of openings. The whole assembly is maintained in position by a spring 11 having a central domed part and a number of limbs extending therefrom which contact the perimeter of the means 15; the spring may consist of a ring member only. On the suction stroke of the compressor gas is drawn from an annular recess 6 through holes 25, openings 26, holes 24, and past the unseated suction valve 14, into the cylinder. On the compression stroke the suction valve 14 is seated and the gas passes through the slots therein, holes 23, and unseats the discharge valve 13, to flow into the cylinder head via the openings in the means 15.

Abstract: 1,254,988. Programmed control of machine tools. SUNDSTRAND CORP. Nov.18, 1968 [Nov.20, 1967], No.29064/71. Divided out of 1, 254, 445. Heading G3N. In a numerical control system for a plurality of machine tools, some of which are capable of performing similar machining operations on a plurality of parts, each part is assigned a process number which identifies the part. A computer 30, Fig.1 retains in its memory the instantaneous location of all parts and tools in the system and effects control of the machine tools 20 accordingly. A parts storage loop 40 is fed from a warehouse arm 250, comprising conveyers 255, each holding a different basic part, from an input conveyer 60. The computer memory is updated in synchronism with movement of parts by photo-electric devices 134. Transfer to a further parts loop is effected by a conveyer 61. The appropriate tools for the programme are selected from a fixed storage area 26 for each machine or from a tool conveyer 81 via a temporary storage conveyer 85. Tool transfer, Fig.3, is effected by each tool 81 being mounted in a car 83, running on rails 280, which is transferred to the conveyer 85 by a ram 350 extending a pair of short tracks across slots in rails 280. The car is disengaged from rails 280 and rolls along rails 300 by gravity until it strikes the legs 340 of a U-shaped member 342. The tool is then transferred to the spindle, (not shown), of the machine tool by a conventional tool-changer 87 having a Y-shaped end claw 380. The member 342 is moved, to correctly position the car adjacent to the claw 380 by a motor, energized by the computer 30, driving a leadscrew 360. When the tool is returned to its car, the computer energizes the motor 350 in the appropriate direction to correctly position the car carrying the used tool in the machining programme. When the programme is complete the member 342 is withdrawn and the cars returned to the conveyer 80 through a gate 230. A tool is removed from the storage arm 269 by rotation under command of the computer and raising the tool by a ram to the level of the claw 380.
