Patent FR-1261999-A (FR)
IPC: E06B3/46
Filed: 1960-04-14
Granted: 1961-05-26
Abstract: 925,760. Sliding-doors. COMPAGNIE DES MACHINES BULL. April 13, 1961 [April 14, 1960], No. 13412/61. Class 20 (3). [Also in Group XIV] Sliding closure or partition panels present, in the closed position, a continuous rail along which any panel which has been displaced from the closed position can run. Each panel 11 is carried on rollers 72 on rails 74, 132 which are displaceable to bring the panel from the closed position into the running position and the rails 74, 132 into alignment with the rails 41, 51 carried by adjacent panels. Two superposed panels 11, 11A may be freed to move together along the rails by operating a latch (Figs. 19, 20, 22 and 23, not shown), to release springs 82 controlling parallel links 77, 78. The links turn about shafts 79, 80 and move the panels 11, 11A outwardly and downwardly. The downward motion releases a latch 150 (see also Figs. 12 and 18, not shown), which enables parallel links on shafts 140 and 141 to move the lower ends of the panels outwardly under spring action. The rails 74 and 132 occupy the positions previously occupied by the rails 41 and 51 and thus enable the two superposed panels to be run off into superposition with a third panel. By repeating the process, any number of panels can be stacked and carried pick-a-back by the innermost panel to any position along the rails. Superposed panels are locked together by a pawl arrangement (Figs. 5 and 6, not shown). The innermost is freed from the lock, on being manually pressed inwardly to retract rails 74, 132, by engagement of member 101 with its pawls. A lock 114 (see also Figs. 8 and 9, not shown), secures the upper latch which co-operates with an arm on shaft 79. A plunger (Figs. 10, 11 and 13-15, not shown), which prevents the panel from being moved when in the closed position, automatically engages the panel in this position. The panels form both side closures for an electronic computer cabinet.

Title: Improvements relating to compressed-air-driven drills
IPC: E21B1/00
Filed: 1943-01-25
Abstract: 559,772. Lubricating. CROFTON & CO. (ENGINEERS), Ltd., C., MANN, R. W., and WILES R. C. Jan. 25, 1943, No. 1258. [Class 12 (iii)] [Also in Groups XXVI and XXII] The vanes 9 of an outwardly-sliding vane typeof motor 12, for driving a drill, are forced outwards by compressed air which is supplied with lubricant. The rotor 10 is provided with a disc 41 to minimise leakage of air from the motor into the gearbox 29. Compressed air is supplied through a cock 5 to a cavity 6, whence it passes through ports in the casing liner to the working space of the motor. A plug 13, which may be adjusted, controls the air flow through a port 15 in accordance with the speed required for the drill to run, that is according to whether stone, hard coal, soft coal &c. is being drilled. Some of the compressed air passes through a passage 26 to a compartment 16 filled with absorbent material such as gauze or cotton wool, soaked with oil. The air, carrying oil, then passes through a strainer 18 to a chamber 19 and a passage 21 leading to a sectorshaped recess 22 in the end wall of the rotor casing to reach the bottoms of the bane slots. Some of the air may pass through a by-pass 23 to 19 without entraining oil, or a needle valve may be used in place of the by-pass. The rotor shaft is connected to epicyclic gears 39, 40, in the gearbox 29, the drive being transmitted through the spindle 30 coupled to a shaft 31 which carries a chuck 32. A rubber shoulder pad 38 is provided. The gearbox is vented to atmosphere.

Title: Double valve gear for single and double acting shaking chute motors
IPC: B65G27/14
Filed: 1921-01-10
Abstract: 157,395. Klerner, H. Dec. 12, 1919, [Convention date]. Fluid-actuated gears; beat or lift valves.--A single or double-acting shaking-shoot motor is provided with two fluid or mechanically actuated lift or slide valves arranged in parallel on one side of the piston, which valves supply simultaneously the pressure fluide for the forward piston stroke. The valves are reversed in succession or simultaneously. A pair of successively-reversing, fluid-actuated valves 2, 3 is shown applied to a single-acting motor, Fig. 1. Fluid enters the passage 1 and passes the valve-controlled passages 4, 6, 8, 5, 7, 9 to the rear cylinder end 10. On the piston passing the ports 13<a>, 15a, the valves 2, 3 are reversed respectively. The main exhaust passes through ports 12, 12a, 12b; an auxiliary exhaust through ports 14<a>, 14b, 14, 17. The cylinder compression on the return stroke returns the valves to the position shown. The ports 13<a> permit regulation of the fluid supply; the ports 15a, 15b, 15<c> permit variation of the stroke. In the double-acting motor shown in Fig. 4, the valve 2 controls a supply of fluid to piston 20 through port 19, and its exhaust through ports 16, 23. The piston 20 may also be controlled by a separate valve. During the back strokes, the valves are returned to the position shown by compression, and by fluid controlled by the piston 20 and admitted to the annular areas of the valves through ports 21d, 21<c>, 21<a>, 21b. A normally double-acting motor, which may be made single-acting by closing valve 24 and opening valve 25, is shown in Fig. 7. Dissimilar valves 2, 3 are provided, and both are reversed by the compression acting on the valve 2.

Title: Photoresistive arrangements
IPC: G01D5/26
Filed: 1973-01-10
Abstract: 1426011 Photo-conductive devices; variable resistors INSTITUT POLYPROVODNIKOV AKADEMII NAUK UKRAINSKOI SSR 10 Jan 1973 1332/73 Headings H1K and HIS [Also in Division G1] A photo-responsive device, e.g. for use as a contactless theostat or potentiometer comprises a pair of series connected photoconductive regions and a light beam different parts of which illuminate respective parts of the two regions. In the Fig. 1 arrangement, disposed on insulating substrate 1, the illuminated parts 8 of photoconductive layers 4, 7 provide a path from earth to a tapping point on resistive layer 2 connected as a potentiometer across the supply voltage. Thus the voltage developed across layer 7 acting as load resistor is linearly related to the beam position but independent of temperature and probe width and intensity. In the Fig. 2 arrangement electrode 12 is effectively a tapping fixed in relation to one end of a potentiometer the length of which, represented by the part of the illuminated portion of photo-conductive layer 9 between electrodes 11 and 13, varies. Output voltage is again a function of beam position but independent of temperature and probe characteristics. Similar considerations apply in Fig. 3 where constant and varying width portions of photo-conductive layer 18 underlying transparent electrodes 19, 20 exposed to the light beam via transparent sections 23 of mask 22 define the potentiometer. In another arrangement (Fig. 4, not shown) comprising an elongate fixed beam aligned with a corresponding elongate photo-conductive layer, an interposed opaque mask movable normal to the beam has two transparent sections one of varying width traversing a part of the layer disposed between a distributed resistance layer and a first electrode and the other, of constant width, traversing a part defined between the first and further electrode.

Abstract: 1,017,301. Tool holders. SOC. DES POUDRES METALLIQUES ET DES ALLIAGES SPECIAUX UGINE, CARBONE. Jan. 11, 1963 [Jan. 11, 1962], No. 1382/63. Heading B3B. A tool holder having means for clamping a chip-breaker in relation to the cutting edge of the tool comprises a body 1 recessed to carry a dispensible carbide tip 4 on a base member 2. A jaw 5 with a recessed port 6 houses a spring blade 7 which supports a projection 9a on a chip-breaker 9. The jaw is provided with a slot 11 through which passes a securing screw 12 for gripping and compressing the chip-breaker 9 and tool 4 between the jaw 5 and the base member 2. Adjustment of the chip-breaker 9 in relation to the cutting edge of the tool is effected by a grub-screw 14 located in an unthreaded bore 16 in the body 1. The rotation of the grub screw in relation to the threaded portion 5a of the jaw 5 permits the advance and withdrawal of the chip-breaker in relation to the tool without affecting the tool position relative to the work. The locking-screw 12 is released and retightened to facilitate this adjustment.

Title: Hydraulic elevator control system
Inventor: BARTHOLMEW JAMES H
IPC: F16K31/12
Filed: 1959-01-14
Abstract: 855,633. Hydraulic lifts. MONARCH ELEVATOR & MACHINE CO. Jan. 14, 1959, No. 1400/59. Class 78 (3). [Also in Group XXIX] A control system for an hydraulic lift comprises a manifold B which extends between a reservoir A and a car-raising ram C, and which contains a pump P, and a non-return valve K arranged to pass fluid towards the ram only; a return line R, R<SP>1</SP> connected to the manifold between valve K and the ram; a by-pass line J3 connected to the manifold between the pump and valve K; and valves O, N and J which control the flow of fluid through lines R, R<SP>1</SP> and J3. In operation, with the car stationary, the back pressure exerted by ram C retains valve K closed, valves O, N and L are closed and valve J is open. Operation of an up-start control in the car or at a landing starts pump P and energizes pilot valve 12 which effects closing of valve J. When the pressure in valve J exceeds that in the ram, valve K opens and the ram is extended to raise the car which, as it nears the selected floor, operates the solenoid of pilot valve 15 which opens valve L. Fluid is then by-passed through valve L and a regulator valve M, the opening of which is determined by the pressure in the manifold, which is proportional to the load in the car, thereby reducing the flow to the ram gradually to a point where valve K closes. When the car reaches the selected floor, pilot valve 12 and pump P are de-energized, and the system returns to its first condition. Operation of a down start control in the car or at a landing energizes pilot valves 18, 19, thereby exhausting the ram through valves O, N and pipes R, R'. As the car approaches the selected floor it de-energizes valve 18 to reduce the rate of flow from the ram, and when at the selected floor it de-energizes valve 19 to stop further movement of the ram. The system is provided with a check valve E which limits the rate of flow from the ram in the event of a fault developing in the system, and a pulsation eliminator F (see Group XXIX), which absorbs pump pulsation shocks. A manually-operable valve 21 permits the rear to be lowered should valves O and N become inoperative. The Specification contains a detailed description of the construction of the valves.

Title: Improvements in or relating to hydraulic change speed gear
IPC: F16H39/24
Filed: 1924-01-17
Abstract: 212,228. Wingquist, S. G. Feb. 28, 1923, [Convention date]. Clutches a n d speed-varying mechanism.- The action of a hydraulic variable-speed gear comprising two or more pumps is controlled by a valve acted on by the pressure in the gear and a spring, and by a cooperating valve, acted on by a spring and centrifugal force due to the rotation of the driving or driven shaft. The form of gear shown comprises two sliding -vane pumps, a rotor 2 on the driving shaft 1 and a stator 10 co-operating with a rotor 5 on the driven shaft 4, and communication between the pumps is governed by a valve 15 acted on by a spring 14 and the pressure in a chamber 12. When the speed of the driven rotor exceeds a predetermined value, a valve 19 moves outwards into the position shown against the action of a spring 18, so that the pressure in the chamber 12 obtains access to the back nf the valve 15 through passages 24, 25 and an annular recess 23. The valve 15 is thereupon returned to its initial position by its spring.

Title: Improvements in or relating to apparatus for indicating the residual range of aircraft or other vehicles
IPC: G01F9/00
Filed: 1957-01-16
Abstract: 858,348. Calculating range of aircraft. NISTRI, R. Jan. 16, 1957 [July 21, 1956], No. 1693/57. Class 40 (1). [Also in Groups XXXVI and XL (b)] The residual range of an aircraft or other vehicle driven by liquid fuel is measured by apparatus comprising a fluid-flow meter which generates signals representing the rate of consumption of the fuel and a calculating device which combines these with a further quantity representing the amount of fuel remaining. In Fig. 1, the photo-cell E generates a pulse once per revolution of the flow-meter 2 situated in the fuel-delivery pipe 1. These pulses are amplified and fed to a gas-filled valve 4 whose pulsed anode current drives the motor M in steps so that its total angular movement is a measure of the amount of fuel consumed. The valve 4 also supplies voltage pulses which are limited in V1, V2 and applied to a conventional capacitor double diode circuit to give on the grid of the triode 7 a signal whose amplitude is proportional to the repetition rate of the pulses and hence to the rate of consumption of fuel. The other triode 6 provides a voltage a fraction of which is tapped off the cathode resistor by a slider driven from the motor M. This/fractional voltage is compared with that tapped off by a similar slider on the cathode resistor of valve 7 and any difference operates the device R (comprising, e.g. a polarized relay or magnetic amplifier) to energize a motor 8 to adjust the left-hand slider until the difference is zero. The pointer and dial 9 driven by the motor 8 then indicate the residual range in hours, assuming the rate of consumption to remain constant. If the grid of valve 6 is supplied with a voltage representing the speed of the craft (Fig. 3, not shown) the indication 9 will represent the residual distance available, assuming no change in the speed and rate of fuel consumption. Fig. 2 shows an alternative circuit for deriving the signal proportional to the rate of consumption, in which the condenser C2 is short-circuited by the valve 4. The average voltage on C2 thus represents the rate, and this is effectively multiplied by the quantity voltage from M in the cathode circuit of valve 6, the motor 8 balancing the bridge and giving the final indication as before. This circuit may be adapted  as above to give a reading in terms of distance (Fig. 4, not shown). The photo-cell arrangement can be replaced by an electromagnetic generator which produces current of frequency proportional to the speed of the rotor. The quantity of fuel remaining can alternatively be measured by a level gauge operating, e.g., a potentiometer.
