Title: Improvements in or relating to piston pumps
IPC: F04B9/115
Filed: 1953-10-05
Abstract: 740,511. Reciprocating pumps. TORKRET GES. Oct. 5, 1953 [Oct. 3, 1952], No. 27219/53. Class 102(1). [Also in Group XXIX] A pump for viscous materials comprises a pair of cylinders containing pistons 8 each of which have racks 9 geared to a pinion 10. The pistons are actuated by hydraulic pressure supplied by a pump 4 enclosed in the reservoir 5, mounted on the carriage 1 which carries the hopper 22. The pumping cylinders 7 are provided with a valve 16 which is oscillated by a pinion 17 driven by a rack formed between pistons 19, 19<SP>1</SP>. The valve has a threaded extension 116 which causes it to move axially as it is rotated. The pressure liquid supply from pump 4 is distributed to pistons 19, 19<SP>1</SP> to actuate the valve and the pistons control the supply of actuating liquid to the pistons 8 so that the pistons are actuated after the valve has been moved to its appropriate position. In a modification as shown in Fig. 7, the discharge pipe is pivotally mounted at 25 and has a curved face co-operating with a seat 26 and is actuated by pistons 1911, 19<SP>111</SP>. In another form the pump body is moved transversely to co-operate with stationary valve seats. In the construction shown in Fig. 12 a single rotary oscillating valve 29 connects the cylinders 7 alternately to the hopper and the delivery pipe 37 and is actuated by cranks 31 and rods 32 connected to a lever 33 provided with a roller that is actuated by cams 35 on the shaft 36 of pinion 10. The pump pistons have heads 8a that have a lost motion connection with the pistons 8 so that the actual pumping of the material does not commence until the valve 29 has been moved. The main distributing valve for the pressure liquid to the pistons 8 is actuated by an auxiliary valve 40 which distributes pressure liquid to pistons contacting the ends of the main distributing valve. The valve 40 is engaged at its ends by coaxial rods 205 which in turn engage a yoke 41 which is reciprocated by spring-loaded abutments 441 carried on the ends of a rack engaging a pinion on the shaft 36. If the valve 29 should be prevented from closing then the pressure of the pressure liquid will rise and open one or other of the safety valves 39 which permits pressure liquid to flow through one or other of the pipes 209 to move one of the pistons 38 into engagement with the yoke -41 to reverse the valve 40 and thus the main distributing valve.

Title: Improvements in or relating to change speed mechanism
IPC: F16H3/083
Filed: 1929-09-07
Abstract: 338,257. McGill, H. Sept. 7, 1929. Variable-speed gearing comprises gears 25 adapted to be selectively clutched to a shaft 10 through the displacement of a plunger 32 in an internal bore 30 in the shaft, such displacement being effected by fluid from a pump. The pump 34 is driven from the driven shaft 10 of the gearing and the oil pumped under control from a bye-pass 35 thrusts plunger 32 to the left of Fig. 1 against the pull of spring 32<1>. The plunger 32 applies a clutch by thrusting out radial pins 29, which in turn thrust spring-pressed dogs 26 outwards into engagement with recesses in the gears 25 &c. The gears 25 &c. are driven from a countershaft 11 and gears 24 with one-way clutches. The shaft 11 is driven from a pinion 13 driven through a clutch 19 on driving-shaft 9. For reversed driving, clutch 19 engages wheel 17, and clutch 40 engages one-way mounted wheel 25<a>.

Abstract: 1345180 Filter A H PARMENTIER 19 April 1971 [14 April 1970 11 Aug 1970 31 March 1971] 27331/71 Heading B1D A filter comprises a tank 1 enclosing rows of flat-sided, rectangular, vertically oriented, inward flow filter elements 7, mounted directly on and extending parallel to respective filtrate outlet pipes 4, and a framework 17, 18, 19 reciprocable by double-acting jack 30 and carrying means 21 which cleans the large surfaces of elements 7. As shown the framework moves horizontally and means 21 are vertical scraper blades, but the blades could be horizontal and the movement vertical, and the blades could be replaced or supplemented by pairs of nozzles (33) (Figs. 4, 5, not shown) which direct jets of wash liquid across the elements. The lower edges of elements are clamped to pipes 4 by upper beams 13 and bolts 12, and their large surfaces are covered by filter cloth or metal screen. The elements and pipes 4 have aligned apertures. Pipes 4 are connected at one or both ends to filtrate collectors 16 leading to a suction pump, or the filter may operate by gravity flow. In one mode of operation, the apparatus acts as a continuous thickening filter, the level in tank 1 is maintained by a float-controlled inlet valve, the framework is moved intermittently in alternate directions, and solids scraped from the elements are removed through outlet valve 32. Alternatively, the tank 1 is periodically drained through valve 32 and the elements cleaned by reciprocation the scrapers and/or wash nozzles. In the latter case, a valve may be provided whereby first and second filtrates are collected separately. The jack and valves could be pneumatically actuated under the control of electric switches operated by respective cams rotated by a timer motor. Blades 21 may be rigid or resilient and may be spaced from the surfaces of elements 7. The framework is guided by bars 25, 29 and runs on wheels 24 in Fig. 3.

The tool 6 is clamped in a removable carrier 5 which is located in the same position on a tool-slide 2 each time after removal by stop pins 13, one of which engages a corner recess in the part 5 and the other bears against a side face. The carrier bears down against the pins by reason of the inclination of the clamping surface 4 formed on the carrier and the top of the slide 2. Bolts 10 secure the carrier, and slots in the latter are sufficiently wide to allow the necessary side movement for location; holes 11, intersecting the slots, are large enough to admit the heads of the bolts to permit rapid changing.

In one embodiment refractory metal oxide is flame sprayed upon the interior surfaces of a gritblasted mould, a bonding material is then applied to the oxide layer and the sub structure is attached. The composite structure is then removed from the mould, the interior surface of which may have been coated with polytetrafluoroethylene to prevent adhesion. In Fig. 2 a forming board in paper making machinery includes a sub structure 21 of say steel or a phenolic resin bonded laminated cloth and overlying the upper surface in a portion of the side of the sub structure is a layer 22 of bonding material such as an epoxy resin. Superimposed upon the bonding material is a coating of ceramic oxide 23 consisting of interleaved laminar layers. A metal mould whose inner surfaces are designed to have a configuration of the outer surface of a coating 23 on the forming board is illustrated in Fig. 3 (not shown). The interior surface of the mould may be prepared by grit blasting and coated with a polytetrafluoroethylene release agent. A mould for forming a multiple foil element for the papermaking machine having three interior corners is illustrated in Fig. 6 (not shown).
