Title: Fluid dispensing apparatus
IPC: B64F1/28
Filed: 1955-08-04
Abstract: 788,818. Delivering liquid fuel and other fluids. STRUVER GES. AGGREGATEBAU, A. Aug. 4, 1955 [Aug. 14, 1954], No. 22467/55. Class 116 [Also in Group XXIX] Liquid delivered by a pump 1, Fig. 1, to a hose 10 passes through a venturi 27 the pressure at the throat 53 of which controls a by-pass valve 44 returning petrol to the suction of the pump. In the construction illustrated a single pump 1 delivers petrol from a tank 3 on a vehicle to two hoses 10. 11 through filters 22, meters 24, and cocks 25 which permit the outlets to be alternatively connected to swing arms 21 or to a return pipe 75. The delivery from the pump is shared between the outlet pipes 19, 20 by a shuttle valve 13 controlled by springs 35, 36 and by pistons 33, 34 connected on one side 39 to the pressure at the throat 53 of the venturi and at the other sides 38 to pitot tubes 40. Each by-pass valve 45 is controlled by a spring 47 and a piston 49 the working space 50 of which is connected to a relay valve 79. Each relay valve 79 comprises a pair of pistons 100, Fig. 3, biased by manually adjusted springs 85 and subject on their lower faces to the pressure at the throat 53 of the venturi communicated through a bore 98 in the stem of the piston 82 and through a conduit 106. When a reduction in the flow through the venturi 27 causes a rise in pressure at the throat the pistons 82 are raised to close a valve 104 connecting the space above the piston 49 to the suction of the pump and a valve 96 is opened to connect the pressure at the throat 53 of the venturi to this space, thus opening the by-pass valve 45. The relay, valve may alternatively be constructed as shown in Fig. 6 in which a single valve member 125 biased by a spring 139 controls an opening 128 connected to the throat of the venturi and has a portion 136 obturating a bore 37 connected to the suction of the pump so that the resultant pressure in the outlet 78 depends upon the extent to which the valve 125 has been forced off its seating 128 by the pressure communicated from the throat of the venturi. The bore 137 is formed in a tube 132 which can be adjusted in a fixed nut 135. In other constructions illustrated in the Specification the space above the piston 49 is permanently connected through a throttling constriction either to a pressure source or to suction while valve controlled by the pressure of the throat of the venturi may connect it to the suction or to the pressure source. The pressures operating the piston 49 may be provided from an auxiliary source instead of from the pressures in the petrol. A diaphragm may replace the piston 49. The pressure at the throat of the venturi may control the by-pass valve through an electrical connection. The apparatus may be mounted on a tank vehicle.

Filed: 1953-08-17
Abstract: 742,960. Valves. CRANE CO. Aug. 17, 1953, No. 22058/53. Class 135. A hinged check valve member 54 is carried by a tubular supporting member which is secured within a chamber in the valve casing by wedge means. According to Fig. 1, the supporting member 23 which is counterbored to fit over a projecting flange 10 of the valve seat is located circumferentially by projections 17, 49 and is secured by a pair of L-shaped wedging members 39. One arm 43 of each member 39 is engaged by a screw 45 which enters a tapped hole in a boss at the side of the member 23 so that the wedging member is drawn downwardly to cause the lower part of the other arm 40 to be wedged between an abutment 16 in the valve casing 1 and an inclined surface 35 on the member 23. A lifting ring 50 facilitates withdrawal of the supporting member 23 after removal of a cover 19. Instead of the member 23 being counterbored to fit over the valve seat it may have an external recess to mate with the seat, more especially when the seat is integral with the casing. In a modification, the supporting member 79, Fig. 3, is held in position by a wedge member 92 of tubular form which is pressed downwardly by a pair of screws 73 threaded in bosses 72 formed in the casing and engaging abutments 98 on the wedge member. The valve closure members may be of circular, elliptical, or polygonal form. Instead of the valve seat being screwed into the casing it may engage a plain bore and be secured and sealed by a plastic substance forced into a space between annular grooves formed opposite each other in the exterior of the seat and in the bore in the casing. Alternatively, a resilient sealing ring may be used.

Title: Method and apparatus for folding sheets
IPC: D06F89/00
Filed: 1971-04-19
Abstract: 1323213 Folding fabrics R L SJOSTROM 19 April 1971 [24 Feb 1970] 23187/71 Heading D1S In a method of folding, a sheet is advanced in a planar configuration, with one edge leading, along a path extending past a first pair of folding rollers until the nip line thereof and an intended fold line in the sheet are in register. The sheet is injected into the nip by air jet or blades to be drawn therethrough to effect a fold the line of which then defines a leading edge of further advancement beyond a second pair of folding rollers which, in similar manner (but by withdrawing the oncefolded sheet in the opposite direction) makes another fold. A compact, simple and readily transportable machine for folding washed and dried, "non-iron" bed and like sheets of finite dimensions may comprise a feeding unit and a receiving platform at a lower level and on the same side of the machine so that an operator loads and unloads the machine from the same position in preparation for manual or automatic cross-folding and/or normal usage. In the operation of the machine shown, Fig. 1, a sheet supplied to a pivotable feeding unit 22 by placing it on endless feeding belts 34 is gripped by means of pressure belts 42 and advanced over a loading bed 28. The leading edge drapes, Fig. 2, and advances downwardly past a folding unit 24 in front of folding rollers 112, 114, 120, 122. Air from a tube 130 injects the (arrested) sheet into nip line 128 to enable the rollers to make the first longitudinal fold which becomes a leading edge draping and advancing beyond the folding rollers on the opposite side thereof. Air from tube 140 injects the folded sheet onto nip line 138 whereby a second fold is formed and the quarter-folded sheet is ejected along a chute 144 to a loading platform. The advance and appropriate arrests of the sheet and the injection of compressed air are controlled by push-button and sheet-edge sensitive, trip feeler or filament actuated, adjustably and/or predeterminedly spaced (according to sheet size) microswitches which in turn actuate, for example, pneumatic valves. As shown in Fig. 8, a cross-folder 186 substituted for platform 26, delivers the fully cross-folded sheet laterally to a receiving station 188. In order to make the cross-folds, the folded sheet is advanced along a bed 190, its midportion is injected downwardly, by air pipe 214 (or a knife 216) through a slot 208 and into the nip line (212) of cross-fold rolls (210) which form a fold as they advance the sheet downwardly along a deflector 228 into belts 220 for transfer to a second cross-folding unit comprising a blade 244 and then a further cross-folding unit (250) whence the sheet is delivered to a table 252.

Filed: 1950-09-21
Abstract: 724.080. Turning-gear. KLOCKNERHUMBOLDT-DEUTZ AKT.-GES. Sept. 21, 1950 [Sept. 23, 1949], No. 23207/50. Class 7 (5). In a spring-powered engine starter of the kind in which a spring 6 is loaded through a spring-energizing mechanism comprising for example an electric motor 21, a shaft 22 and a friction clutch 28, 31 which is coupled to the engine crankshaft so that rotation of the mechanism to load the spring 6 also turns the crankshaft in its operational direction of rotation, the mechanism is drivingly coupled to the starter and crankshaft through the yieldingly engaged clutch elements 28, 31 which are declutched by re-action of the loaded spring 6 thereby releasing the spring to turn the crankshaft when the spring is loaded. Construction. The spring 6 is secured at its inner end to a hub that has a pawl and ratchet connection with the engine crankshaft whilst the outer and is engaged in a housing 15, which latter end the flywheel 3 have toothed circumferences 16 and 18, respectively. A drive to both the housing and flywheel is provided by pinions 20 and 19, respectively, pinion 20 being of larger diameter than pinion 19 ; a hollow shaft 30 upon one end of which the pinion 19 is formed has at its other end a threaded part 29 and the clutch member 28. The other clutch member 31 has an extended hollow shaft terminating in the pinion 20 and enclosing a part of the shaft 30. The clutch members are yieldingly engaged by a spring 33 the force of which is adjustable by shims. The shaft 22 of the electric motor 21 passes through shaft 30 and has a threaded portion 27 engaging with the threaded part 29 whilst clutch member 31 has teeth on its periphery engageable by a paw 40 to prevent reverse rotation of the housing 15. Operation. When the motor 21 is energised, rotation of shaft 22 threads clutch member 28 into engagement with the fixed member 31 so that both pinions 19 and 20 are driven at the same speed, but since pinion 20 is of larger diameter than pinion 19 the housing 15 is driven faster than flywheel 3 thereby tensioning the spring 6 until such time as the turning moment of the spring is greater than that capable of being transmitted through the clutch, whereupon the clutch slips and, due to the difference in speed between member 28 and shaft 22, the member 28 is threaded leftwardly disengaging the clutch, thus enabling the spring 6 to accelerate the engine. The electric motor may be replaced by a hand drive operating through pawls arranged to drive the engine in its normal direction of rotation and the spring housing in the opposite direction until the spring is fully tensioned.

Abstract: 1535771 Adjustable vehicle suspension units GIRLING Ltd 14 May 1976 [28 May 1975] 23273/75 Heading F2S A suspension unit for the rear wheel of a motor cycle comprises a telescopic hydraulic damper 1, 4 and a coiled compression spring 7, one end of which abuts against an adjustable sleeve 8, rotation of which results in axial adjustment to compress the spring to a greater or lesser extent. The sleeve 8 has a cam surface which cooperates with a similar surface on a rotatable intermediate sleeve 12, which itself co-operates with a sleeve 2 fixed to the end of the damper body. The sleeves are shown spaced apart merely for clarity. The fixed sleeve 2 has angularly spaced recesses of two different depths, and the intermediate sleeve 12 has correspondingly spaced fingers 14, 14<1> of different lengths. Rotation of the intermediate sleeve 12 through 90 degrees to move the longer finger 14<1> from the deeper to the shallower recess results in a small axial movement of the sleeve 12 to adjust the spring. Further adjustment is possible by relative rotation of the sleeves 12 and 8, the identical profiles of which give three distinct axial positions. Rotation is effected by means of a C- spanner which co-operates with notches in a flange at the end of each sleeve. Specifications 713,214 and 1,267,513 are referred to.
