Title: Stock feeding mechanism
Inventor: SHOTTER DOUGLAS RALPH
IPC: B23B13/00
Filed: 1962-11-30
Abstract: 984,625. Bar-feeds. EDWARD WILLIAMS HOLDINGS Ltd. Oct. 15, 1963 [Nov. 30, 1962], No. 45326/62. Heading B3B. Mechanism for feeding bar-stock (not shown) to a machine-tool 28 comprises a guide-tube 6 containing a stock-pusher, Fig. 3 (not shown), which is connected to a cable &c. and a fluid-pressure actuator 14, 15, 16 driving the cable through a one-way coupling 19 the actuator including a vane 16 movable through less than 360 degrees. The tube 6 is pivoted at one end to a support 7, the extent of pivotal movement for re-charging the tube being limited by the engagement in a pivotal link 29 of a pin on the actuator which is at the other end of the tube. An ear on the pusher engages the cable through a slot 10 in the tube, the cable passing round a pulley 23 keyed to a shaft 12 mounting a handwheel 22 and on which rotates the rotor 13 of the actuator. Rotation of the vane 16, Fig. 5, in the chamber 14 restricted by a wall 15, is transmitted through a pawl-and-ratchet 19 to one half 20 of a clutch, the other half of which, on the shaft 12, is engaged by endwise movement of the shaft. The mechanism and a pneumatic chuck may be controlled by three valves (not shown). The first opens the chuck, the second supplies air to the chamber 14, through one of two ports 17, 18 for advancing the pusher, and the third closes the chuck and supplies air to the other of the ports, returning the vane 16 in preparation for another feed step. After disengaging the clutch 20, 21, the handwheel 22 may be turned for retracting the pusher to receive a fresh stock-bar.

Title: A multiway repeater switching valve
IPC: F15B21/08
Filed: 1966-10-11
Abstract: 1,113,073. Fluid-pressure control valves &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. 11 Oct., 1966 [15 Oct., 1965], No. 45361/66. Heading F2V. A multi-way repeater switching valve comprises a valve body 10 and two reciprocable closure members 20 and 22 which repeatedly make and break one of two fluid passages extending between two inlets 12 and 14 and one outlet 16. If both closure members are reciprocated in phase with respect to one another then at the instant of members 20 and 22 being in their lowermost position (as seen in the drawing), inlet 14, connected, e.g., to a pressure supply, communicates with the outlet 16 through passages 36, 42, 36a, 48 and 36b. In the other extreme position, a similar connection is made through ducts 34, 42, 34a, 48 and 34b. Alternatively if the two closure members are reciprocated 180 degrees out of phase with respect to each other, then upon member 20 reaching its lowermost position member 22 is in its uppermost position thereby bringing into communication port 12, e.g. vacuum, and outlet 16 through ducts 30, 38, 30a, 44 and 30b. With positions reversed the same connection is made, but through ducts 32, 40, 32a, 46 and 32b. Thus depending on the relative phase of the two closure members a connection between either one of ports 12, and 14 and port 16 is repeatedly made and broken. Reciprocation of the two members is achieved by moving coil actuator assemblies 24 and 28 basically comprising a permanent magnet 50, a soft iron cap 54, a restoring spring 60 and a coil 58. Terminals A, B, E and F are connected to electrical circuits (Fig. 2, 4 and 5, not shown), which periodically actuate the assemblies and provide the means for shifting the phase of one closure member with respect to the other, this being done by holding stationary for one halfcycle one of the two closure members when it attains either one of its two extreme positions. The switching valve, which may comprise more than two closure members, is designed for use in hydraulic tape transporting mechanisms which use pressure and vacuum to control the movement of tape from one capstan to another.

Abstract: 957,859. Regulating fluid flow. SPERRY RAND CORPORATION. Dec. 17, 1962 [Dec. 28, 1961], No. 47499/62. Heading G3H. Apparatus for producing pulses of fluid pressure at an outlet 22 and suitable for use in fluidoperated data processing equipment comprises a sheet 14 of metallic or plastic &c. material formed with a cutout section providing an inlet 20 leading through an orifice 26 to the outlet 22 and to a control chamber 24, and sandwiched between a pair of plain sheets one of which carries a supply tube 30. The fluid, which may be gas or liquid, passing through the orifice 26 normally discharges to the outlet 22 but in so doing induces a reduced pressure in the chamber 24 which causes the discharge to be deflected into the chamber 24 until the pressure therein has risen to an extent to allow the discharge to return to the outlet 22. The frequency of the pulses so produced in the outlet 22 is variable by adjustment of a piston 36 or of the amount of heat developed in a heating filament in the chamber 24. An auxiliary opening at right-angles to the discharge from the orifice 26 may be provided to assist the deflection of the fluid stream and to influence the frequency, and such opening may be connected to atmosphere, to a source of pressure or to a point in the outlet 22. The chamber 24 and piston 36 may be cylindrical. The number of inlets, outlets and control chambers may be varied.

A stationary original 1 is illuminated by a moving light source 2 which traverses in Fig. 1(a) from left to right. The light reflected from the original passes through an optical system comprising a pair of parallel mirrors 3, 5 having a lens 4 interposed between them, the optical system as a whole moving at half the speed of the light source, in the same direction. Finally the light is reflected through a slit 7a in a stationary shield 7 to fall on a lightsensitive copy sheet 6 moving in the same direction as the source 2, at the same speed. Thus a complete image of the original 1 is produced on the sheet 6. Fig. 4 shows the arrangement applied to an electro-photographic copying machine, the copy sheet 6 being disposed round a drum, with a charging unit 10 and developing unit 11. The original 1 is scanned by the moving light source and optical system as above described, the light being reflected through slit 7a on to sheet 6 on the rotating drum. The image is transferred to a sheet 17 from a supply roll 17a at a station 12, then fixed at station 19 and passed out between rollers 18. The sheet 6 then passes a neutralizing electrode 14 and cleaners 15, any residual powder being fed to a container 16. Fig. 5 (not shown) is a machine in which the image is fixed directly on the light-sensitive sheet, without any transfer operation. In this case a further mirror (21) is provided to give a right-reading image.

Abstract: 1495724 Liquid level indication CERMAT 7 Nov 1974 [8 Nov 1973] 48303/74 Headings G1H and G1N A device for sensing the level of liquid in a tank comprises two probes opening at known levels in the tank, one below the liquid and one above, the pressure difference between the probes giving an indication of liquid level. On the level rising to the second probe opening, the level reading due to pressure difference is checked against the known level of the second probe and adjustment made if necessary. Several probes providing several such checks may be provided. As shown, all but the lowermost probe are connected to a "valve" 22 which renders effective for checking purposes only that probe immediately above the liquid level. A transducer 20 feeds a signal corresponding to the pressure difference to a processing circuit 28 via a variable load 24, the circuit 28 providing signals adjusted by the load and in a form suitable for a numerical display 32. The display provides both liquid depth and specific gravity. The load 24 preferably comprises a rheostat controlled by a signal from a comparator 42. When the rising liquid reaches a sensitive probe, e.g. 18, a locking circuit 34 is triggered and transmits a signal to lock the display reading on 32. It also triggers a memory unit 40, which feeds a signal corresponding to the known level of the probe 18 to the comparator 42. The other input to the comparator 42 is a signal from 28 representative of the liquid level as measured, and a difference signal, if any, is fed from the comparator 42 to adjust the rheostat of load 24. Alternatively the load 24 could be manually adjusted in response to an alarm triggered by the sensitive probe.
