Title: Improvements in or relating to hydraulic actuating mechanisms
Inventor: ROLLITT JOHN
IPC: F15B7/10
Filed: 1960-09-02
Abstract: 926,505. Hydraulic apparatus; valves. ARMSTRONG PATENTS CO. Ltd. Aug. 23, 1961 [Sept. 2, 1960], No. 30260/60. Classes 69 (2) and 135. An hydraulic actuating mechanism comprises a closed hydraulic circuit having conduits 52. 53, Fig. 3 (Comp.), arranged between a pump 50 and motor 51, and fluid-pressure responsive means 55 connected between the circuit and a reservoir 54 to compensate for changes in the volume of the fluid in the circuit. The fluidpressure responsive means may consist of a valve formed by a ball 45, Fig. 2 (Comp.), which, during operation, is urged against a seat 41b by the pressure in a bore 40a connected to the conduit. When the pump and motor is inoperative, the ball is moved from its seat by a spring or gravity a distance determined by a pin 46 to permit liquid to pass in one direction or the other between the conduit and reservoir 42 to compensate for temperature changes on the volume of liquid in the circuit. Air in space 48 acts to pressurize fluid liquid in the reservoir. Each conduit may be provided with a unit consisting of a reservoir and pressure-responsive valve, the two units being arranged in a common housing having bores 40a, 40b connected to the conduits. In another embodiment, a housing 5, Fig. 1 (Prov.) is provided with a threaded bore 5a for insertion in a conduit between the pump and motor and a plug 12 having a threaded bore 12c for connection to a reservoir. The plug secures a sleeve 6 in the housing and a piston 7 is slidable with clearance in the sleeve and is formed with a seating 7a engaged by a spring-pressed valve member 8. When the pressure in the bore 5a connected to the conduit is less than that in the bore 12c in the plug connected to the reservoir, liquid from the reservoir can pass a seal 13, through the space between the sleeve 6 and piston 7 and through passages 7b in the piston to the conduit. If the pressure in the conduit is greater than that in the reservoir, the piston is urged upwardly into engagement with the seal 13 to prevent flow to the reservoir. If the pressure differential between the conduit and reservoir exceeds a predetermined value, the valve 8 opens to permit liquid to pass to the reservoir. In a further embodiment, the valve 21, Fig. 3 (Prov.), is urged to a closed position by a diaphragm spring 22 and the movement of the piston member 17 is limited by a circlip 19. The plug 15 is formed as a reservoir and a vent 24 permits air to escape during filling of the system. Two similar units each consisting of a pressureresponsive valve as shown in Fig. 3 (Prov.), and a reservoir may be arranged in a composite unit and the liquid in the reservoirs may be pressurized by spring-pressed pistons. In another arrangement, the piston 25, Fig. 4 (Prov.) of the pump and/or motor is hollow to form a reservoir and a fluid-pressure responsive valve is provided in the head of the piston. Specification 826,229 is referred to.
Patent GB-1516562-A (GB)
Title: Process of and apparatus for bonding foils or veneers to boards
IPC: B29C65/10
Filed: 1976-07-21
Abstract: A dispersion (emulsion) glue is applied to the surfaces to be glued. The glue is then completely dried by warming to about 100 DEG C. Before bringing together the surfaces to be glued, the dried glue is warmed to its softening point. The surfaces are then pressed against one another until the glue has set. The process permits gluing of pre-glue-coated foil strips (13), as edge material, in particular onto chipboard panels (1). The glue-coated and dried foil strips are drawn off from a roll magazine (stock roll) (12). The softened glue gives clean (tidy) glue joints, at high travel speeds and with a short glue-setting zone. Workpieces (1) and foils (13) or veneers can be glue-coated simultaneously. Before being brought together, the glue-coated surfaces can be first dried by means of a joint air supply duct for warm air (9), having exit nozzles (11, 16) on both sides, and can then be warmed further until the glue softens. <IMAGE>

Title: Improvements in and relating to voltage stabilising apparatus
IPC: H02M3/33
Filed: 1948-11-29
Abstract: 657,141. Converting; automatic voitage control systems. COSSOR, Ltd., A. C., and COVILL, D. H. Nov. 29, 1948, No. 30971. [Classes 38 (ii) and 38 (iv)] Apparatus for producing a stabilized, unidirectional high potential of the type comprising a discharge tube having an inductance in its anode circuit, a steep fronted waveform being applied to the grid of the tube so as to generate voltage surges in the inductance which surges are rectified to produce the high potential, has means provided to derive a unidirectional controlling potential whose magnitude is dependent upon that of the high potential, this controlling potential then being applied to the grid of the tube to render it more or less negative when the high potential tends to increase or decrease respectively, thereby to reduce variations in the high potential. Potentials having a steep fronted waveform, or pulses, when applied to the control grid of a valve V1 produce voltage surges in the primary winding L1 of a transformer T, which pulses are then rectified to provide a unidirectional high voltage across the condenser C2. Corresponding voltage surges will also appear in the secondary winding L2 which when rectified, are applied to the control grid of the valve VI in such a sense that any variation in the voltage across the winding L1 will be reduced. Another component of the bias voltage is obtained from the tapping on a potentiometer VR1, this component being kept constant in spite of variations in the H.T. potential by the presence of a neon stabilizing tube N. The adjustment of the position of the tapping on the potentiometer determines the value at which the unidirectional high voltage is stabilized.

Title: Improved phosphonitrilic chloride purification process
IPC: C01B21/098
Filed: 1963-08-09
Abstract: Cyclic trimeric and tetrameric phosphonitrilic chloride polymers are recovered by passing an inert gas through a crude molten mixture of polymers, contacting the laden gas with an inert solvent, and evaporating the solvent. The inert gas, e.g. air, CH4, N2, CO2 or a rare gas, at between ambient temperatures and 200 DEG  C., is pumped through the molten mixture at 120-170 DEG  C., or passed upward countercurrent to the melt.  High polymer residue is removed, and the gas passes to a cylindrical packed or baffle tower, where it is stripped by the solvent at 0-100 DEG  C. in countercurrent and may be recirculated through the melt.  The polymer solution is recycled until 15-35% concentrated, and passed to an evaporator where the vaporized solvent is removed and condensed.  The liquid product passes to a flaker in which it is spread on a cooled inert moving surface, e.g. a revolving drum, and removed by scraping.  The solvent has a boiling point of 100-200 DEG  C., e.g. monochlorobenzene, benzyl chloride, phosphorus oxychloride, tetrachloroethylene, or sym.-tetrachloroethane. The crude starting mixture may be obtained by reacting NH4Cl with PCl5 in an inert solvent, and impurities removed by treatment with an adsorbent, e.g. fuller's earth, silica gel, acid treated clay, bone char, or bauxite, followed by filtration; both steps being at 100-150 DEG  C. under reflux.  The adsorbent may be added to the reaction zone or to a separate zone, or used in fixed bed.  The solvent is then evaporated, preferably below 140 DEG  C. and under vacuum.  Linear polymers may be removed by dissolving a petroleum ether, filtering, and evaporating.
