Title: Improvements in or relating to inflating valves for pneumatic tyre tubes and other inflatable articles
IPC: F16K15/20
Filed: 1937-12-15
Abstract: 492,851. Inflating-valves. JENKINS BROS. Dec. 15, 1937, No. 34783. Convention date, April 14. [Class 135] An inflating-valve for pneumatic tyres, football bladders, &c. of the kind comprising a stem or body portion 10 of rubber or like resilient material formed with an air passage 12 having a shoulder 13 which forms a valve seat, has a conical valve member 15 pressed by means such as a spring 19 against an annular line edge seat 13c formed by the junction of substantially conical and cylindrical portions 13a, 12a of the air passage respectively, the valve member extending beyond the seat in all its possible seating relations. The angle of the conical portion relative to the axis of the stem is greater than that of the valve member 15. The stem 10 has a flap 11 which is preferably only semi - cured so that on being vulcanized to the tyre or the like it attains about the same condition as the stem. The air passage 12 merges into a conical part 13b, Fig. 4, which adjoins the conical portion 13a, but is not tapered as much. Above the cylindrical channel 12a, the passage widens for the reception of a tubular insert 14 of brass or the like which has a re-entrant flange 14e which backs the valve seat and lies substantially normal to the lines of pressure exerted thereon by the valve member 15. The flange 14e also forms a seat for the spring 19 which also engages a head 17 on the valve spindle 16. The head 17 is freely slidable in the converging upper end 14b of the insert but prevents the entrance of foreign matter. In a modification, the flange 14e is replaced by a separate conical part pressed into the belled lower end of the insert, and the spring is located below the valve member, the latter having a depending projection. An annular spring abutment is pressed into the passage 12. Other modifications are shown in which the stem 10 is reduced substantially to the length of the valve 15 and its spindle 16 and in these the flap 11 may be at either end of the stem part or at an intermediate position. Specification 440,840 is referred to.

Abstract: 1,125,732. Programmed control of machine tool. ROLLS-ROYCE Ltd. Aug. 9, 1966, No.35664/66. Heading G3N. [Also in Division G4] Apparatus for testing the size of a workpiece 2 (Fig. 1) during machining includes two nozzles 18, 18' which are moved until the pressure in channels 19 leading to the nozzles is at the required value so that the nozzles 18,18' are at a predetermined distance from the workpiece 2, the distance between the nozzles being continuously monitored to give an indication of the workpiece size. The distance between the caliper arms 15, is measured by a MoirÚ fringe device 23, the distance being compared with the required distance which may be stored on punched or magnetic tape 26 and the error signal on line 31 being used to position a cross slide 12 holding a grinding wheel 10 relative to the workpiece 2 so that the workpiece is ground to the required size. The required length of the workpiece is also stored on tape so that a signal representing the difference between the required and actual lengths of the workpieces may be used to control a machine bed 5. Since the width of the grinding wheel 10 affects the length of the workpiece a further pair of nozzles 34 adjacent opposite faces of the wheel 10 are used to control the axial position of the wheel. The length and diameter measuring unit are connected to a print out device 25 to give a visual indication of the size of the workpiece. In one embodiment the nozzles 18,18' are controlled by servo means pressure transducers converting the fluid pressures into electrical signals which are compared with a reference signal representing the required pressure in a comparator 22 and the error signal used to drive motors 17. In a second embodiment in which the caliper arms are driven independently, the electrical signals from the transducers 21, 21' are applied via amplifiers (40, 40') Fig. 2 (not shown) to servomotors (42, 44). In a third embodiment Fig. 3 (not shown) each nozzle (18) is connected to a diaphragm (64) which is moved as the pressure in a channel (19) varies deflecting a further diaphragm (72) and so altering the restriction to flow presented by a needle valve (70) to vary the pressure in a channel (71) and so move the first diaphragm (64).
