Abstract: 1,267,653. Drying webs. SINGER-COBBLE Ltd. 11 March, 1969 [18 March, 1968], No. 12970/68. Heading F4G. [Also in Division F1] A dryer for sheet material has a planar drying surface parallel with the sheet material and comprising a plurality of multi-apertured air supply regions and suction orifices so arranged that all parts of the material receive similar treatment in whichever of two perpendicular directions it passes the drying surface. Air is drawn past a gas heater by a fan 14 and blown out through perforated surfaces 12 on to the web to be dried e.g. a latex backed tufted carpet. The fan simultaneously applies reduced pressure to the ports 13 so that the air is drawn back into the housing 11 and past the neater. The heater may be replaced by heating or cooling coils at C, or omitted altogether. The perforated surfaces 12 are at an angle to the walls of the housing 11 so that the web to be dried may be fed under the drier in either of two perpendicular directions. The ports 13 decrease in size towards the heater end to maintain uniform treatment across the web. Explosion panels comprising glass fibre wadding sandwiched between frangible strips are provided in housing 11. Two pairs of individually controllable drier housings may be arranged on each side of the web, Fig. 5 (not shown). Webs of different widths may be accommodated by a laterally adjustable stenter having a concertina like shutter for blanking off the unused portion of the drier, Fig. 6 (not shown).

Title: Improvements in pulsing arrangements for electron discharge devices
IPC: H01J25/12
Filed: 1944-07-06
Abstract: 584,452. Pulsing carrier frequencies. WESTERN ELECTRIC CO., Inc. July 6, 1944, No. 12970. Convention date, July 9, 1943. [Class 40 (v)] An electronic discharge device is controlled by pulses derived from the discharge of a condenser . which is charged from source of power and discharged through a keyed electronic switch in such a manner that its potential is combined with that of the source in controlling the electron discharge device. The electron discharge oscillator 1 is controlled by potentials applied to its cathode 2 from the condenser 24. With the key 28 open the valve 22 is non- conductive and the condenser 24 is charged from the source 19 through the resistances 25, 26 and the shunting diode 23. On completion of the charge, the accelerating-electrode 3 assumes the same potential as the cathode 2. On closing the key 28 the valve 22 becomes conductive and the condenser 24 discharges through the valve 22 and the resistance 25, the diode 23 being non-conductive. The impulsive potential thus produced across the resistance 25 renders the cathode 2 negative to the electrode 3 by a potential approximately that of the source 19 and causes the tube 1 to operate as a generator. The invention may also be applied to an amplifying tube (Fig. 2, not shown). In a modified arrangement (Fig. 3, not shown) the condenser 24 is charged to a potential less than that of the source 19. The electron discharge device may be of the type described in Specification 555,162 or may be an ordinary thermionic valve.

Title: Vehicle braking system
IPC: B60T8/50
Filed: 1959-04-16
Abstract: 883,019. Fluid pressure brakes. CITROEN S.A., ANDRE. April 16, 1959 [April 16, 1938], No. 12982/59. Class 103 (1). A vehicle, fluid pressure braking system includes a deceleration responsive device and means for incrementally decreasing the pressure. applied to the brake actuators at each operation of the deceleration responsive device. On braking, pedal 7 moves plunger 5 against spring 6 to connect pressure accumulator 2 to the rear actuators 1 via pipe 3, plunger 5 and valve 17, 18, a switch 21 being closed by pedal 7 to operate stop lights and to energize solenoid valve 20, 22 to disconnect accumulator 2 from a primary accumulator 10 and pump 11. When the deceleration exceeds a predetermined value an inertia switch 16 closes to energize solenoid valve 17, 18 to release pressure from actuators 1 to reservoir 19; the wheels then accelerate to re-open switch 16, de-energize valve 17, 18 and re-apply pressure to actuators 1, but, since accumulator 2 is cut off from the primary accumulator 10, at valve 20, 22, the brake pressure is lower, by a definite amount, than it was initially. This process is repetitive. The front brakes are applied via plunger 14 from accumulator 12. In Fig. 2 (not shown), the plunger 5 on depression cuts off the communication between accumulators 2 and 10, whilst in Fig. 3 (not shown), this communication is closed by valve when fluid pressure is delivered to actuators 1. Specification 883,018 is referred to.

Abstract: 1530294 Protective apparatus; electrostatic generators; protecting converters SCIENCE RESEARCH COUNCIL 29 March 1976 [27 March 1975] 13050/75 Headings H2H H2A and H2F In order to protect the components of a high voltage D.C. source 1 from the effects of surges originating in the environment of the output terminal 2 of the apparatus, two resistorcapacitor stages are connected between the source 1 and the output terminal 2, the stage adjacent the output terminal having the shorter time constant. A practical arrangement of the apparatus is shown in Fig. 2 wherein the power source 10 comprises a transformer 13 connected to a Cockcroft-Walton voltage multiplier 15, the output of which is connected to a ceramic type resistor 18. The components of the multiplier 15 effectively form a capacitance C 2  which, together with the resistor 18, form an R/C network R 2 C 2 . The resistor 18 is connected to a series of resistors 20 which form a resistor R 1 , the resistor 18 furthermore being surrounded by a cylinder 19 which is itself surrounded by a cylinder 26. The cylinders 19, 26 constitute a capacitance C 1  which together with the resistors 20 forms a second R/C network R 1 C 1 . The resistors 20 are finally connected to a terminal 12 forming the high voltage output terminal of the apparatus, a spark gap being provided between the terminal 12 and the end plate 24 of the cylinder 26. The two stages in conjunction with the spark gap between the terminal 12 and endplate 24 provides protection against fast and slow surge voltages. Protective apparatus of this type can be used with an electrostatic generator as disclosed in Specification 1,401,182. Such a generator is shown in Fig. 3 and is provided with electrodes 40, 41 each having their own power supplies P/S combined with protective apparatus 42, 43 as shown in Fig. 2.

Title: Apparatus for supplying desired quantities of pumpable feedstuffs
IPC: A01K5/02
Filed: 1976-03-31
Abstract: 1485927 Feeding animals SCHMEING Gebr 31 March 1976 [26 April 1975] 13057/76 Heading AIM Apparatus for supplying a desired volume of pumpable feed to a feeding station comprises a container 8 charged and discharged through an aperture 7 and having the volume of feed therein limited by a piston 9 having a piston rod 10 engaging an adjustable abutment 14. A valve 2 controls connection of the aperture 7 with a feed supply pipe 1 and with an outflow duct 5 leading to a feeding trough 6. The valve 2 is pivoted at 18 and biassed anti-clockwise by a spring 20 tensioned by rotating a crank 19 through 180 from the position shown. When the spring is so tensioned, supply of feed under pressure through pipe 1 pivots the valve 2 until a bore 16 therein registers with the aperture 7 and feed is supplied to the container up to the limit determined by the piston. Thereafter continued supply of feed through pipe 1 causes the valve 2 to move further clockwise and close the aperture, and feed can then be supplied to downstream storage containers in an animal feeding installation. When all the containers have been filled the pump is switched off and each valve 2 is moved by its spring 20 to the position shown, in which feed flows from the container to the feed trough 6. When the spring tensioning crank 19 is in the position shown, supply of feed through pipe 1 shifts the valve 2 fully clockwise to a position closing the aperture 7, and feed can be pumped through pipe 1 around the whole installation to achieve a thorough mixing.

Title: Improvements in or relating to fluid dispensing devices
IPC: B65D47/16
Filed: 1939-05-02
Abstract: 528,272. Bottles and stoppers. SCHWAB, M. C. May 2, 1939, No. 13097. [Classes 125 (i) and 125 (iii)] A fluid dispensing device and an air filter form a structure which is suspended in the neck or body of the container, and the filter chamber forms a seal to prevent contamination of the discharging fluid. The neck 6 of the container C, Fig. 1, has an insert 8 with ends 12, 13 having an orifice 15 in the outer end 12; a tube 9 extends through both ends, and a tube 16 extends through the end 13 nearly to the bottom of the container. The insert and tubes may be made of metal, glass or plastics, and the insert may be a hollow member enclosing the chamber 14, or its ends 12, 13 may be connected by webs 20, 21. A cap 7a may be provided for the container. After the cap has been removed from the charged container, the tip 24 is taken from the beaded end of the tube 9 and a hypodermic needle 26 or any other device to be used for the discharge operation is attached to the tube. The filled container is inverted and the liquid in the tube 16 drops into the chamber 14 of the insert 8. Liquid passes from the container through the tube 9 and the attached device and the air which enters the container passes from the orifice 15 through the liquid in the insert, and this liquid thus acts as a filter to protect the main quantity in the container. Where the container neck is of clear glass the rate of flow and the action may be observed. In a modification the air filter chamber is in the container itself and the connecting tubes pass through an insert in the neck. In one form of this type, the tubes and the chamber are made integral as shown in Fig. 7. The parts are supported by the insert 8b and when the container is charged, the liquid level is just below the opening 11b so that it flows into the chamber 14b. Upon inversion of the chamber for dispensing purposes, fluid leaves the container by the opening 11b and the tube 9b so that no sediment is discharged. Air enters by the orifice 15b, passes through the tubes 16b, 19b, the orifice 20b, and then bubbles through the liquid retained in the chamber 14b. A tip 10b may be used as a seal to cover the fluid outlet and the air inlet orifice. Various arrangements of tubes and filter chambers are described ; in each case the sizes of the fluid outlets and air inlets are such that no fluid flows from the filter chambers when the devices are inverted. Valves may be used to control the inflow of air.

Title: Improved servo-control mechanism
IPC: B64C13/24
Filed: 1943-08-17
Abstract: 569,749. Fluid-pressure servomotor-control systems. TRIPP, E. J. Aug. 17, 1943, No. 13331. [Class 135] In a hydraulic servomotor comprising a double-acting piston, a piston valve slidable therein, and resilient means between the valve and piston, the piston is locked hydraulically when the valve is in neutral position relative to the piston and may be moved against a light load through the resilient means, hydraulically against a heavier load or through a lost-motion device if the power supply fails. As shown for actuating aircraft ailerons or equivalent members, a lever 13 connected to the pilot's control column is linked to a piston valve 32 slidable in the double-acting piston 29, and the member to be actuated is connected through a lever 16, link 40 and pin 45 to the piston 29. Springs 60a, 60b tend to keep the valve central with respect to the piston, whatever the position of the latter, so that liquid supplied by a pump through a port 19, and a groove or grooves 53 passes through ports 51a, 52a to the interior of the valve, and thence through openings 33, 34 to return to the pump or supply tank, the working spaces 48a, 48b at the ends of the cylinder 23 being sealed so that the piston is hydraulically locked in position. The valve has slots 43 receiving the pin 45 so as to allow the valve to be moved out of its central or neutral position by the lever 13, so as to allow liquid to pass to one end or the other of the cylinder through ports 54a, groove 59a and ports 55a, liquid from the other end being exhausted through ports 56b, 58b. These ports are subsequently closed by the follow-up movement of the piston. If the load on the lever 16 is light, motion is transmitted by the springs 60a, 60b without the aid of pressure liquid. Should the liquid supply fail, motion is transmitted by an end of the slot 43 engaging the pin 45, a non-return valve 62a or 62b permitting liquid to enter one working space while it escapes from the other through ports 56a and groove 58a. The levers 13, 16 may be mounted to turn about a common axis.

Title: Improvements in or relating to the Utilisation of Centrifugal Forces Developed from a Weight Rotated or Oscillated about an Axis.
Inventor: MAUDE FREDERICK NATUSCH
IPC: F03G3/00
Filed: 1916-09-20
Abstract: 109,123. Maude, F. N. Sept. 20, 1916. Self-driving machines; momentum power-storing apparatus.-Relates to the utilization of centrifugal forces developed from a weight connected to an axis about which it can be rotated, and consists in movably mounting the axis in such a way that the centrifugal force of the weight pulls it away from the true centre of rotation, thereby absorbing the centrifugal force and converting it into work. Energy will thereby be developed and a part thereof employed to maintain the motion. In one form, the piston-rod B of an oscillating cylinder N is provide with a heavy bob to constitute a pendulum, the centrifugal force of which acts against a spring R under the piston. Through the trunnions O, air or liquid is admitted at one side (for example through the passage O<1>) to the interior of the cylinder past a non-return valve, and upon pressure being exerted thereon by the piston, air or water is forced out under pressure through the discharge outlet O<2> into an accumulator; or such aeriform fluid under pressure may be utilized in any other desired manner. Another form consists of a revolving weighted arm attached to the guided end of a lever which is linked to a ratchet lever. In order to make the circular motion of the weight continuous, any suitable mechanical or electric means may be provided to impart an impulse just as the weight arrives at the zenith; for example a part of the energy stored up or obtained through the lever may be employed to operate a spring arm with trigger release. The ratchet lever operates a barrel winding up a cord from which a weight is suspended.
