Patent GB-1302650-A (GB)
IPC: D02J1/22
Filed: 1971-04-19
Abstract: 1302650 Spin-drawing polyethylene terephthalate filaments SOC DE LA VISCOSE SUISSE 19 April 1971 [15 April 1970] 23010/71 Heading B5B  In a continuous process polyethylene terephthalate filaments 2 are extruded from an extruder 1, quenched by a blast of air 3, lubricated by a finish applicator system 5 and the resultant filaments are drawn at a draw ratio of at least 5À0, prior to wind up 8 at a speed of at least 1,800 metres/min. by passing them from a feed roll system 6 comprising at least two cylindrical rolls to a draw roll system 7 comprising at least two cylindrical rolls in which the axis of the feed roll from which the filaments leave and the axis of the draw roll at which the filaments arrive are parallel and the axes of the rolls in the feed roll system and the axes of the rolls in the draw roll system respectively are skew set, the surface temperature of the feed rolls is 75-130‹ C., the surface temperature of the draw rolls is 180-240‹ C., and each roll in the feed and draw roll systems has a surface roughness which allows the filaments to slip during 1 to 5 turns before they leave the feed rolls and after they arrive at the draw rolls, gradual drawing of the filaments being thereby started as they pass round the last 1-5 turns of the feed rolls and completed after 1-5 turns on the draw rolls. The preferred surface roughness of the feed and draw rolls is defined in the Specification in terms of specific measurable quantities, the surfaces of the rolls being roughened by, for example, controlled sandblasting followed by galvanic metal coating, depositing metals in crystalline form from a gaseous phase or by affixing small metallic globules of different sizes so that feed and draw roll surfaces consist of a coherent non-porous coating of tiny, smooth-topped elevations of unequal height and irregular distribution. The lubricating finish applied to the filaments before stretching is suitably a mixture of isooctyl stearate and an ethoxylated emulsifying agent preferably containing not more than 10% by weight of water. Examples relate to the production of polyethylene terephthalate filaments with draw ratios above 5À0 using feed and draw rolls heated to within the specified temperature range. In Examples IV-VI the filaments are pre-tensioned prior to stretching and relaxed and stabilized at 235‹ C. using heated relaxation rolls after stretching and prior to wind-up.

Title: Liquid fuel pumps for internal combustion engines
Inventor: KEMP KENNETH ALBERT WALTERS
IPC: F02M59/36
Filed: 1960-07-01
Abstract: 954,493. Fuel injection pumps C. A. V. Ltd. June 6, 1961 [July 1, 1960], No. 23045/60. Heading F1A. In a fuel injection pump in which injection is terminated by uncovering spill ports 29 in the plunger 14 by a sleeve 30, the movements of the sleeve relative to the plunger are related to the setting of a valve 34 controlling the outflow from a chamber 20 in which an annular piston 32 loaded by a spring is slidable. At low speeds the sleeve is held against a shoulder 14a on the piston 28 and moves with the piston until a sleeve part 30a engages an axially adjustable part 20 to terminate delivery. If the engine speeds exceeds that for a predetermined setting of the valve 34, the pressure in the chamber 21 and on the piston 32 rises whereby the piston 32 causes the sleeve 30 to lag behind the plunger and so uncover the ports 29. During the suction stroke of the plunger 14, fuel is admitted to the chamber 21 through the valve 34 and through the piston 32 by virtue of the piston 32 lagging behind the sleeve 30, since the spring 33 is weaker than the spring 31. In a modification, the spring 33 bears against a second abutment on the plunger 14 instead of on the fixed barrel 12. In an alternative embodiment (Fig. 2) the spill ports 58 are covered by a sleeve 59 which is normally held in contact with a collar 56 by a spring 60. A bush 61 is slidable on a spigot 62 and controlled by an eccentrically mounted pin on a shaft 64. A piston 65 having a central scalloped hole receives the inner end of the sleeve 59 and can move axially between a flange 59a on the sleeve 59 and the collar 56. An orifice in the piston 65 is provided radially outside the flange 59a. On the plunger suction stroke the piston 65 lags behind the sleeve 59 and on the delivery stroke the piston abuts the sleeve and fuel can only pass through the orifice in the piston. If the engine speed is excessive, the pressure in chamber 51 acts on the sleeve 59 causing it to lag behind the plunger 44 until the spill ports 58 are uncovered. The quantity of fuel supplied is controlled by an adjustable stop 71 for the sleeve 59.

Title: Improvements in or relating to propellers more particularly for aircraft
IPC: B64C11/00
Filed: 1922-08-24
Abstract: 203,178. Schiesari, M. Aug. 24, 1922. Screw propellers.-The blades of an airscrew are coupled to the shaft and to each other by a continuous flexible cable. The cable is passed around a drum, and by winding in or out the blades have a radial movement and the effective diameter of the propeller is altered. Such alteration may be effected automatically, and diameter variations may be combined with pitch alteration. An extensible propeller with variable pitch includes a cable 1, Figs. 5, 6, which is attached at 3 to and wound round a core 2 on the shaft 4. The cable passes in series over sheaves 27, 28 in a frame 21 on which the blades 22 are pivotally mounted at 23, 24. The sheaves are threaded and carried on fixed screws 25, 26. Rotation of the sheaves by the cable winding in or out therefore results in overall diameter variation and also pitch changes as the sheaves move longitudinally on the screws. For winding in or out the cable, the core 2 is held to the shaft frictionally between two discs 5, Fig. 7, having roller studs 6 over which the cable runs. The external disc 5 has a chamber 12 with a non-rotating piston 14 screwed on to an extension 16 of the shaft. Rotation of the reel relative to the shaft results in longitudinal movement of the piston which motion is controlled by the air pressure in the cylinder. Under increased centrifugal force the blades move out and the piston moves into its cylinder increasing the pressure until it balances the new centrifugal force effect. In a modification a spring is substituted for air pressure, one end being attached to the outer disc and the other to the shaft. Locking pins 34 carried by a collar 20 can be moved in or out by levers under the pilots control when it is desired to fix the blades and cut out the automatic control. For manual control only, the external disc may have a coned extension which coacts with a brake member slidably mounted on the propeller shaft the brake being under lever control. To maintain the blades radially in the retracted position when the screw is stationary, the pivots 23 of the frames 21 have a guide piece 7 which slides between the discs 5. The frames 21 also have tubular cable guides 46, 47. The sheaves 27, 28 may be interconnected by chain and sprocket gearing. For helicopters two oppositely revolving screws of different diameter and pitch are employed. For landing a helicopter or aeroplane, the blades are arranged to assume a negative incidence in the most retracted position.

Title: Improvements in or relating to measuring apparatus
IPC: G01F9/00
Filed: 1956-07-27
Abstract: 821,061. Fluid measuring apparatus. RAMSHALL, J. D. July 17, 1957 [July 27, 1956], No. 23349/56. Class 40 (3). Light-sensitive cells are operated by the level of liquid in a container to measure the time period taken for a quantity of liquid to flow into or out of a container and/or to measure an effect dependent on the liquid and that time period, e.g. the rate of consumption of and the number of revolutions performed by, an engine when supplied with a known quantity of fuel. In Fig. 1, the glass container 14 receives the liquid fuel from a feed pipe 11 via the electrically-operated valve 12 and the engine is connected to feed pipe 13. At each of the four container reference levels 21, 22, 23 and 24 light is directed through the container and operates a photo-electric cell when the liquid is below that level, each cell is connected via an amplifier to a relay which can operate when the cell is illuminated. The supply voltage, connected to the unit via switch 42 operates the valve 12 which allows the container to fill to a level 17. Fuel between the lamp and photo-cell at level 21 prevents relay SR1 from operating, thus lighting the lamp 46 to indicate that the apparatus is ready for use. Operating switch 56 is pressed closing the valve 12 so that fuel for the engine is now drawn from the container 14. The fuel level falls below level 22 operating relay SR2 which switches on the revolution counter 51 and the time meter 48. The fuel level in falling below level 23 operates relay SR3 opening the operating coil circuit of relay SR2 and switching of the counter and timer. The volume of liquid between levels 22 and 23 is a known quantity. The further reduction in the level of the liquid below level 24 operates relay SR4 which opens valve 12 and resets the equipment for the next test.

Title: Improvements in or relating to a rotary fluid pressure converting device such as a turbine, compressor, pump or the like
IPC: F04D25/04
Filed: 1954-08-12
Abstract: 761,937. Compressors, pumps and turbines; gas turbine plant. GARRETT CORPORATION. Aug. 12, 1954 [Aug. 21, 1953], No. 23425/54. Classes 110 (1) and 110 (3). A turbine, compressor, pump or the like comprises a rotor rotatably mounted within a casing and having primary blading thereon, secondary blading associated with the rotor, and passage means for contiguously conducting the flow of primary blading fluid and of secondary blading fluid and so positioned that the flow of secondary blading fluid forms a flow boundary layer thereabout. In the centrifugal compressor shown the impeller comprises a back-plate 16 carrying substantially radial blades 17 having their entry edges 18 bent in the direction of rotation. Axial-flow fan blades 30 are formed on a cylindrical ring 31 mounted on the entry edges 18. The centrifugal compressor blades 17 discharge into the usual volute 28 by way of diffuser blades 27, while the axial-flow fan blades 30 discharge through a passage 33 to an annular chamber 36 containing vanes 35 and thence to an outlet 40. A fairing cone 42 is supported from an annular wall 37 by struts 43. The main stream of air flowing through the inlet passage 41 to the centrifugal compressor flows concentrically within the annular stream of air flowing towards the axial flow fan. The annular stream forms a boundary layer which protects the main stream from disturbances caused by frictional drag on the wall 37. The centrifugal compressor may supply air for combustion in a gas-turbine plant, while the axial-flow fan supplies air to a heat exchanger for cooling lubricating oil. The centrifugal compressor may be operated as a centripetal air turbine, the axial-flow fan then drawing in air from the former outlet 40 and discharging it through the passage 41 to form a boundary layer around the discharge from the turbine. The air flowing to the fan may be used as a coolant in a heat exchanger. The invention may be applied to pumps and turbines operating with inelastic fluids or liquids.

Filed: 1936-08-27
Abstract: 480,364. Door handles &c. RAMSELL, H. G., and TAYLOR, J. W. Aug. 27, 1936, Nos. 23519 and 30118. [Class 44] A spring-loaded door knob has fixed to it a member which engages one end of a loading spring and also co-operates with an adjustable stop to limit its movement. This stop may be adjusted or removed to permit movement of the member to a position in which the action of the spring on the handle is reversed. The handle 7 has attached to it a member 10 which has a lug 12 engaging the end of the spring 4 and recesses 13 and 14, either of which may co-operate with a stop 15 to limit movement of the handle and member. To reverse the action of the handle and the spring, the stop 15 is removed, the handle turned through 180‹, and the stop 15 replaced. This allows the lug 12 to engage the other end of the spring, and the end previously in engagement abuts against the lugs 5, 6 of the spring housing. These lugs 5, 6 are constructed so as to allow the passage of the lug 12 during this movement. A modification in which the spring and housing are arranged on the face of the door separate from the rose plate as well as various methods of making the stop and co-operating member are described. The spring-loaded door handle, Fig. 18, is rotatable in either direction, the lug 31 being adapted to engage either end of the spring 26, the other end of which will engage the fixed abutments 29, 30.
