Title: Method for processing unstabilized polyvinylchloride
IPC: B29C48/08
Filed: 1970-06-24
Abstract: 1317323 Extruding polyvinylchloride KONINKLIJKE MACHINEFABRIEK STORK NV 24 June 1970 [24 June 1969] 30582/70 Heading B5A Unstabilized polyvinyl chloride polymer is moulded, e.g. by extrusion or injection, by pressurizing particles thereof in a first zone to a temperature between the glass transition and melting points, i.e. 80 to 120C., and then melting the particles, i.e. at 180 to 220 C., predominantly by shear, but which may be supplemented by conducted heat, in a second processing zone over a residence time of less than 20 sees., e.g. 10 to 20 seconds, and through which the polymer is passed to be formed, by means of the pressure developed in the first processing zone. The zones, which are independently heated and/or cooled are preferably insulated from each other, e.g. by an air gap, and in an injection machine, the nozzle thereof serves as the second zone. In an extruder the screw or screws, of low or zero compression ratio, comprise the first zone acting as a conveyer to the second zone wherein the shear is developed by a mandrel, spider, or the tip of the screw which may be varied in speed independently of the screw conveying portion thereof. In the examples: (1) suspension polymerized polyvinyl chloride powder is extruded, at 90 C., by a 15 length to diameter ratio and average 4 mm. channel depth screw into a second zone at 190 C. comprising a tubular die of 2 mm. depth and from which a 70 Á film is blown; (2) a rod is extruded utilizing an 8 length to diameter ratio non-compressive screw of 3 mm. channel depth, and which is provided with a conical tip of the same angle as that of the die entry; (3) and (4) non-compressive twin screws, heated to 90 C. by oil circulating therein, extrude into a second zone defined by screw tip clearances which decrease from 10 to 4 mm., followed by a torpedo and a 2 mm. clearance tube die from which film is blown;(5) the screw of example (1) is provided with a cylindrical tip joined thereto by a conical portion.

Title: Control apparatus for compressors operating in parallel
IPC: G05D16/20
Filed: 1972-06-29
Abstract: 1385983 Automatic control of pressure TRANS CANADA PIPE LINES Ltd 29 June 1972 [29 June 1971] 30597/72 Heading G3R In a compression station having at least two compressors working in parallel, the station discharge pressure is controlled using a pressure control, for each compressor, which is fed with a station discharge pressure error signal via a gate operated according to the flow error in the compressor. In the embodiment described, the station includes three compressors in parallel Fig. 1 (not shown), feeding a gas pipe-line, signals representing the actual flow to or from each compressor, as measured e.g. by an orifice, being fed to terminals A, B, C, and a signal representing the station discharge pressure to input N. A desired flow for each compressor is obtained from the actual flow signals using integrator 34, and potentiometers 44-46, that set the proportion of total flow supplied by each compressor. The actual and desired flows are compared in detectors 51-53 to energize relay coils 57a to 62a according to the flow error in each compressor. Controller 63 compares the actual and required station discharge pressures, on inputs N, 64 respectively, to provide "raise" or "lower" signals according to whether the actual value is below or above the required value, these signals passing via conductors D to M to control the speed of a turbine driving each compressor. A fast response is obtained by using speed dependent signals for each turbine, from potentiometers 87-89, which are fed to controller 63 via summer 90 and amplifier 91, that has a variable gain dependent upon the number of compressors in use. Contacts 57 to 62, energized by coils 57a to 62a, ensure that only "raise" signals are applied to the turbine control if the actual flow is lower than desired, and only "lower" signals if the actual flow is higher. Other sets of contacts e.g. 41, 41', 41" and 42, 42' and 42" ensure that the "lower" or "raise" signals are ignored when pre-set speed limits are exceeded.

Abstract: 226,564. Maybach Motorenbau Ges. Dec. 22, 1923, [Convention date]. Fluid-pressure; hand and foot actuation.- In brakes of motor-vehicles of the kind which are applied by a pedal or hand lever until a certain pressure has been imparted to the brakes, the pedal &c. then operating the controlling-means of an auxiliary hydraulic brake which completes the brake application, the initial brake pressure is transmitted from the arrn k of the pedal i to the brake blocks q through a spring m and lever o, the hydraulic brake coming into action only when the arm r begins to compress the spring s, whereby the opening f is throttled by the valve t, and a supplementary braking effort is exerted by the piston u and its piston rod v, which increases with the pressure on the pedal. By providing two-springs s, and so arranging them that initially only one is subject to compression the hydraulic braking effect may be more gradually developed. The pump gear a<11> which effects the oil circulation through the pump circuit d - - h is driven from the engine by the pump gear a which also drives the gear a<1> serving to supply lubricating oil to the engine. A valve w is provided in the base of the conduit d to ensure that the chamber e is always filled with oil.

When lever 38 is released spring 34 closes valve 25, 52. During filling, a tank is pushed on to outlet 54, 55 to engage abutment 56 to move the burner and body 6 against the action of spring 7. Ports 45 are moved clear of ring 10 and fuel flows through channel 29, ports 28, 45 to the lighter reservoir as shown by a dotted line. When the fuel reaches lever 51 it flows up channel 50 between a sleeve 49 and nipple 5, through ports 46 to atmosphere so that a user can recognize when the lighter is full. Ring 10 normally closes ports 45 and 46. A simplified valve arrangement in Fig. 1, not shown, has no means of telling when lighter is full and the movable part of fuel valve 25, 52 is not fixed to the burner.
