In a pump having a disc-like impeller obliquely mounted on a driving shaft and surrounded by a casing with a clearance which is uniform along the periphery of the impeller, the impeller is circular or is an entire ellipse or the periphery of the impeller has two straight parallel portions connecting the two part-circular portions. Fig. 8 shows a pump having an inclined-disc impeller of circular or elliptical form but cut away at opposite ends to form chords 106, 107 adjacent the stuffing box 108 and inlet duct 109. The interior of the pump casing conforms to the solid of revolution generated by rotation of the impeller. As shown, the casing is divided along an inclined plane into two flanged portions. The inclined-disc impeller 83 shown in Fig. 3 is of elliptical form when viewed in the normal direction 80 and of circular form when viewed in a direction 81 perpendicular to the shaft 102. Alternatively, the impeller may be of circular form when viewed in the direction 80 so that it is of elliptical form when viewed in the direction 81.. As shown in Fig. 9, the impeller may have teeth fitting into annular grooves 113 machined in the pump casing. To permit insertion of the impeller, the casing is divided along two planes 114, 115 into four flanged parts 116, 117, 118, 119. The grooves 113 are machined as described in Specification 949,461. When the material handled by the pump has a high content of solids, as in the manufacture of paper, the inlet and outlet ducts are of large diameter, the diameter of the outlet duct preferably being equal to that of the casing, and the inlet duct is preceded by a funnel. Specification 879,546 also is referred to.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/46
Filed: 1943-11-03
Abstract: 594,006. Hydraulic shock-absorbers. FOCHT, N. S. Nov. 3, 1943, No. 27114/46. Convention date, Oct. 30, 1942. Divided out of 593,954. [Class 108 (iii)] Relates to a hydraulic piston-and-cylinder shock-absorber of the kind in which liquid is forced from the cylinder 10, Fig. 2, into a reservoir c, and vice-versa, as the piston moves in one direction or the other in the cylinder. According to the invention, the flow from the cylinder to the reservoir is controlled by. a spring-closed metering pin 25 adapted to be actuated by the liquid pressure and arranged so that its throttling effect first diminishes and then increases as the fluid pressure increases; return of liquid from the reservoir to the cylinder being, controlled by a check-valve 27. As shown, the lower end of the shock-absorber is closed by a head 14 comprising a shell 17, valve seat member 18 and a plug 19, the shell 17 which is threaded on the lower end of the cylinder containing a groove 15 for the lower end of a tube 12 constituting the outer wall of the reservoir c. The plug 19 is screwed into the shell and is formed with projections 21 which hold the member 18 in position in the shell, spaced from the plug, and which form communicating ducts between the cylinder chamber b and the reservoir through ports 23 in the shell. The metering pin 25 is formed with oppositely-tapering parts 28, 29; Fig. 4, for controlling flow of liquid through an orifice 24 in the member 18 and normally is held in the position shown by a spring 31 which also bears on the check-valve 27, and by a spring 36 which forces a shoulder at the lower end of the pin against the top of a tube 32 threaded in the plug 19. Adjustment of the tube 32 varies the normal position of the metering pin parts 28, 29 relatively to the orifice 24. Outwardly-opening ball or other valves 41 acted on by leaf or other springs 42 control flow of liquid through ports 40. The shock-absorber piston is provided with valve means as described in Specification 593,954 while the upper cylinder head is provided with gaskets as described in Specification 594,007. Operation. Compression of liquid in the chamber b forces the metering pin 25 downwardly so that the part 28 leaves its seat and opens the orifice 24 to permit progressivelyincreasing flow of liquid from the chamber b to the reservoir through the ports 23 until the part 29 of the pin begins to co-operate with the orifice. With continued increase in pressure, the part 29 progressively-decreases the area of the orifice 24 increasing the resistance accordingly. On excessive pressure the valves 41 open. On rebound, as the pressure in chamber b decreases, the springs 31, 36 return the metering pin to its normal position, closing the ports 24, and the valve 27 is drawn open to allow liquid to flow from the reservoir to chamber b through ports 36.

Abstract: 759,040. Seed sowers. SANDOR, B. T. Jan. 5, 1955 [Oct. 5, 1953], No. 27235/53. Class 6 (1). A seed sower comprises a rotary dispenser 6 adapted to receive seeds in or on seatings 8 and rotatable inside a sleeve 1 having apertures leading into a hopper 11 and apertures 15 through which the seeds are deposited, the dispenser being provided with an air jet pipe 5 and being so shaped that compressed air flowing through the pipe 5 causes a lowering of pressure in the dispenser, thus causing seeds from the hopper to adhere to the seatings. As the dispenser rotates an outlet nozzle 7 for the compressed air is obstructed by a shield 10 causing the seeds to be ejected through the openings 15 in the sleeve. At the same time compressed air is blown through openings 14 to agitate the material in the hopper. A number of dispensers may be mounted on a tool-bar attached to hydraulic lift arms of a tractor, all the dispensers being actuated by a common shaft driven either by the power take-off shaft or by the rear wheels of the tractor or by landwheels. The compressor may also be driven by the tractor engine. The dispensers are preferably operated in conjunction with means for opening and closing the furrows. Each dispenser may be combined with one or more units to deposit fertilizer. Instead of one run of seatings, two or more may be provided. The seatings may be interchangeable to suit different sizes or shapes of seed. The shield 10 may be adjustably positioned to adjust the position where ejection of the seeds takes place. Compressed air may be admitted continuously or intermittently into the hopper from the pressure supply line, and the hopper may have an adjustable outlet valve to regulate the pressure thereon.
