Title: Improvements relating to apparatus for the production of solutions of foam-stabilising compounds in water
Inventor: HENSHAW THOMAS ANTHONY
IPC: A62C5/00
Filed: 1958-07-21
Abstract: 855,188. Mixing fluids in flow in definite proportions. PYRENE CO. Ltd. July 10, 1959 [July 21, 1958; Nov. 10, 1958], Nos. 23337/58 and 36027/58. Class 86 In an apparatus for adding a certain small proportion of foam stabilizing compound to water, the low-pressure zone of a venturi is connected both to a supply of foam stabilizer and to a supplementary supply of water, the supplementary water supply being regulated automatically to be the inverse of that of the main supply so that the supply of foam stabilizer, being complementary to the supplementary water supply, varies directly with the main flow. In Fig. 1 the main stream of water 3 is supplied to foam generators 1 by a pump 4. Water is taken from the main stream below the pump 4 and supplied by a pipe 8 to a venturi 7, the lowpressure zone of which is connected to a supply of foam-stabilizing compound 5 and to a supplementary supply of water bypassed from the pipe 8 through a flowregulator 10 having a lenticular chamber containing a vane 11, see also Fig. 6, (not shown). The vane 11 is mounted on a common shaft 14 with a vane 15 in the main water flow 3, see also Figs. 3 and 5 (not shown) in such a way that as the vane 15 is deflected by an increasing flow of the main stream the vane 11 is moved to reduce the flow of water through the regulator 10. The flow of water through the regulator acts on the vane 11 in such a way as to provide a restoring force for the vane 15. In an alternative arrangement, Fig. 9 (not shown), the supply of water to the low-pressure zone of the venturi is regulated by a butterfly vane which is mounted on a common spindle with a flap valve in the main stream and a flow regulated in a by-pass the flow in which opposes the movement of the flap valve. In another modification the flow regulator may be replaced by a simple valve and the vane in the main stream spring-loaded against the flow.

Title: Improvements relating to melt spinning
Inventor: UPTON EDWARD JAMES
IPC: B29C48/05
Filed: 1956-07-30
Abstract: High linear polymers are melt-spun by feeding the molten polymer to at least one uniformly heated closed circuit header system from which it passes to a number of spinning heads by means of which it is extruded in the form of filaments, the volumetric rate of flow of the molten polymer in the header system before it reaches the spinning heads being in <PICT:0839202/IV (a)/1> excess of the total rate at which the molten polymer leaves the system through the spinning heads, preferably by a factor above 1.5 and especially about 1.75-2.5 or more.  As shown, polymer chips are fed through the feed opening 4 into a melting chamber 1 provided with a jacket 7 communicating with a melting grid 5 so that a heating fluid may be passed through the jacket and the grid.  The molten polymer flows from the sump 6 into a housing 17 containing two gear-wheel circulating feed pumps 18 connected to the sump by lines 19 on their input sides, and to two closed circuit headers 2 by lines 20 on their input sides and lines 21 on their output sides.  A feed line 22 serves to supply a heating fluid to the housing 17.  Each closed circuit header 2 comprises out and return lines 23, 24 respectively enclosed within a common jacket 25 communicating with the housing 17 so that heating fluid can flow from the housing into the jackets, and provided at their other ends with connections 26 to a heating fluid return line 27, to which also leads the outlet 12 from the jacket 10 round the lower part of the melting chamber.  The jackets 25 are discontinuous, being interrupted by the spinning heads 3 round which the heating fluid is conducted by by-passes 28.  A supply line 29 for additional heating fluid, provided with a control valve 30, enters each header jacket 25 beyond the last spinning head.  The spinning heads 3 connected to the closed circuit headers 2 are conventional in structure.  Each is provided with a jacket for heating fluid fed from the corresponding by-pass 28 by a supply line 31, and communicates by a drain line 32 with the heating fluid return line 27.  The invention enables a number of spinning heads to be supplied from a single melting chamber without decomposition or depolymerization of the molten polymer. Specifications 839,201 and 839,210 are referred to.

Filed: 1923-09-20
Abstract: 224,655. W³nsch, G., and Askania-Werke Akt.-Ges. vorm. Centralwerkstatt-Dessau und C. Bamberg-Friedenau. Sept. 20, 1923. Fluid-actuated valve s.-Apparatus for the frictionless transmission of motion comprises a nozzle effecting a primary movement and conveying a current of air or liquid under pressure which is directed in accordance with the movement towards one or other of two adjoining openings of two pipes leading to the ends of a cylinder, either the cylinder or its contained piston being moved accordingly. Fig. 1 shows a tube a which can be oscillated by motion imparted to a lever e, so that the nozzle d of the tube is brought more or less in front of one of the adjoining pipes f, g communicating with the opposite ends of a cylinder h adapted to slide on a fixed piston i. Air or liquid under pressure is being discharged through the nozzle, so that the cylinder is caused to follow the motion of the nozzle which is parallel and proportional to that imparted to the lever. By keeping the cylinder fixed, the motion of the nozzle causes a greater pressure on one side or other of the piston which may be moved accordingly. Fig. 4 shows a device for regulating gas pressure in a pipe 1 by connecting it with a diaphragm chamber 3, the diaphragm of which is linked to a pipe 6 which may be freely oscillated about a pivot 7 and conveys air or liquid under pressure. This fluid is conveyed by pipes 8, 9 to a cylinder in which it moves a piston 11, the rod of which is caused to turn a throttle valve 13 in the gas pipe 1, in accordance with the pressure. Fig. 5 shows apparatus for delivery of a gas and air mixture of adjustable uniform composition, in which gas and air supply pipes 15, 16 fitted with throttle rings 26, 27 deliver into a chamber 36. The pressure differences at these rings actuate diaphragms 28, 29 which operate push rods 30, 31 connected to a lever 32 and a tube 25 conveying a fluid under pressure, respectively. A slide block 33, mounted on a rod 34 which may be adjusted by hand, is interposed between the lever and the tube so that the motion of the tube delivers the compressed fluid to opposite ends of a cylinder 20, the piston of which actuates a throttle valve 17 in the air pipe 16.

Abstract: 934,079. Windscreen cleaning systems. DELMAN CO. June 30, 1961, No. 23701/61. Class 138 (1). In a windscreen cleaning system, including a suction-operated wiper motor and a suction device for controlling a washer pump, the wiper motor is controlled by a diaphragm suction device incorporating a delay means whereby the wiper motor continues to operate for a period after the washer pump has ceased to operate when the two have been started simultaneously. Manual operation of a control valve 47, Fig. 1, applies suction from the vehicle air intake manifold through a hose 51 to a diaphragm 99 (not shown) in a housing 91, Fig. 2, to actuate a cable 93 to pull a lever 77 against the action of a spring 84, and bring the driving wheel 90 of the washer pump 27 into engagement with the fan belt 21, thus starting the pump 27. Simultaneously the valve 47 applies suction through a hose 52 to a diaphragm 163, Fig. 8, in a time delay device 54 to actuate a cable 159 operating a control valve 40 (Fig. 1), to start the wiper motor 39. Upon release of the operating member of the control valve 47, the latter is returned by a spring to its original position. The hose 51 is then opened to the atmosphere and air pressure assisted by a spring 103 (not shown) returns the diaphragm 99 to its original position to stop immediately the washer pump 27. At the same time the hose 52 is cut-off from the atmosphere and the diaphragm 163 returns to its original position under the action of a weak spring 167 assisted by atmospheric air which is bled into the chamber 141 through felt plugs 169. The stopping of the wiper motor 39 is thus delayed.
