Title: A device for the regulation of pressure in sliding vane rotary compressors
IPC: F04C28/00
Filed: 1938-01-07
Abstract: 509,247. Rotary compressors. KLEIN, SCHANZLIN, & BECKER AKT.-GES. Jan. 7, 1938, No. 507. Convention date, Jan. 8, 1937. [Class 110 (ii)] Means for regulating a rotary compressor comprise regulators 9, 17, on the suction and delivery sides, and a byepass valve 2 which when opened by a spring 4 connects the delivery pipe 1 with a pipe 5. Fluid under pressure in the inlet pipe 6 acts through a pipe 7 to raise a plunger 8 and allow the fluid to pass through a pipe 11 to a space 12 and thus force down the valve 3. The compressor can then deliver fluid past a non-return valve 14 to a receiver 13. As soon as the pressure 'in the receiver reaches a predetermined figure, a plunger 16 is raised and a pipe 19 is opened to the pressure fluid to allow the latter to pass under the head of the valve 3 and lift the valve. When the pressure in 6 falls, the plunger 8 also falls and allows communication between the space 12, through the pipe 11, to the atmosphere. The spring 4 then raises the valve 3 bringing about no-load running conditions. Valves 20 prevent compression in the cells C when the pressure in the delivery pipe falls. The spring 4 may be replaced by another force. Reference has been directed by the Comptroller to U.S.A. Specification 1,922,639.

Abstract: 1412215 Centrifugal pumps JONKOPINGS MEKANISKA WERKSTADS AB 4 Jan 1973 [12 Jan 1972] 568/73 Heading F1C A centrifugal pump 3 is connected via a separator tank 2 and a suction pipe 1 to a container or tank (not shown) to be emptied, liquid being recirculated from the pump delivery pipe 6 to the pump inlet 4 only when the liquid in the separator tank is below a predetermined level, gas separated from the liquid in the separator tank being diffused into the recirculated liquid on the suction side of the pump, the resultant mixture of liquid and gas being pumped by the pump 3. A jet pump 9 is energized by liquid recirculated from a horizontal portion of the delivery pipe 6 via a pipe 8 containing a valve 10 which is opened, as by a switch actuated by a float 11, when the liquid level in the tank 2 falls, and draws in the gas via orifices 13 in a tube 12. The lower the liquid level, the more orifices 13 are uncovered by the liquid and hence the greater the flow of gas. The tube 12 may be covered by a slidable or rotatable sleeve for covering a selected number of the orifices 13. The mixture of liquid and gas may be directed towards the impeller eye to break down accumulations of gas or may be introduced into the pump with pre-rotation. A baffle 5 may be omitted.

Title: Method and apparatus for measuring liquid flow-volume
IPC: B01L99/00
Filed: 1959-01-08
Abstract: 858,731. Liquid meters. LEONARD, J. H. Jan. 8, 1959 [Jan. 29, 1958], No. 809/59. Class 69 (1). A liquid flowmeasuring device for insertion in series within a liquid flow circuit, comprises a first reservoir 20 including a permanently non - obstructed inlet 22 and an outlet 26; a second reservoir including an inlet 30 and a permanently non - obstructed outlet 35; the outlet 26 being connected through a valve 53 with the inlet 30; and a vent 52 connecting the upper portion of the reservoir 20 and the upper portion of the reservoir 21; flow through the device, when the valve 53 is open, being free and unobstructed; the closing of the valve for a relatively short time permitting volumetric measurement of flow quantities within either or both reservoirs without changing the rate of flow through either the inlet 22 or the outlet 35. Volumetric calibrations 28, 36 are marked on the reservoirs 20, 21. In operation, the lower reservoir 21 is filled with the liquid being measured to any arbitrary level.T he apparatus is then connected so that the entire flow of the system passes through the apparatus. Under non-measuring conditions, the level of the liquid will remain constant. The reservoir 20 and that part of the reservoir 21 which does not contain liquid is filled with a gas which is inert with respect to the liquid. To measure the rate of flow of liquid the valve 53 is closed for a measured interval of time. The liquid in the reservoir 21 will flow through the outlet 35, the reservoir 20 will be filled with liquid and the gas will be displaced through the vent 52 into reservoir 21. At the end of the fixed time period the level in reservoir 20 is measured using calibrations 28. In a modification shown in Fig. 4 an elastically deformable cylindrical housing 37 is provided with a diaphragm 45 having a baffle wall 48 and a vent hole 47. The capacity of the upper reservoir 20 will thus increase from bottom to top so that low values of reservoir volume are accurately gauged.

Abstract: 1,193,803. Exposure control systems. EASTMAN KODAK CO. Jan. 6, 1969 [Jan. 4, 1968], No. 828/69. Heading G2A. A camera diaphragm comprises a vane 9 with a tapered opening 11, which co-operates with a mask 15 to define the diaphragm aperture, the mask being movable to an inoperative position at low light intensities. As shown, the vane 9 has a supporting arm 7 on which is wound the coil 5 of a galvanometer, and is normally spring- biased clockwise. The coil is in circuit with a photo-cell 1, and when energized by light falling on the cell, is rotated anti-clockwise, thus aligning a narrower portion of opening 11 with the camera lens 13. The mask 15 is pivoted on a pin 21, and normally biased clockwise by a spring 25. It has pincer-shaped ends 17 which block part of the light admitted by the opening in the vane (position of Fig. 1). A second circuit, including a battery 35, will, when the circuit is closed, drive the coil 5 clockwise (i.e. in the opposite direction to the photo-cell 1). Under normal light intensity conditions, only the photo-cell circuit is operative, and the brighter the light the more the vane turns anti-clockwise. As the light intensity falls off, the vane returns clockwise under its restoring spring, and at a certain predetermined intensity the contacts of switch 41 are closed. A further switch 37 is closed when the shutter release is pressed, so that when switch 41 is also closed the battery circuit is completed. The EMF of the battery 35 is greater than that of photo-cell 1 under low light intensity, so that the coil is now driven clockwise. A shoulder 45 on the vane 9 engages a finger 47 on mask 15 and swings it entirely out of the light path, so that the diaphragm aperture is now of maximum size Fig. 2 (not shown).

Abstract: 538,870. Double-acting fixed-cylinder pumps. ZWICKY, J. Jan. 16, 1940, No. 959. [Class 102 (i)] In a hand- or power-operated double-acting fixed-cylinder reciprocating pump, the cylinder casting 1 is formed on one side, and in a plane parallel to the axis of the cylinder 2, with a flat seating 15 connected with the ends of the cylinder by passages which are separated from each other by a partition 13 at right angles to the cylinder axis, the seating 15 being engaged by a separately formed valve plate 16. The latter carries four valves 20, two of which are inlet valves opening downwardly, and two are outlet valves opening upwardly, one valve of each kind being disposed on each side of the partition 13. Each valve 20 comprises a rimmed disc with a stem which is surrounded by a spring 19 arranged between the plate 16 and a collar 21. The valve chest is completed by a valve box casting 23 having a closed top 25 and a partition 24 which is parallel to the axis of the cylinder and which makes joint with the valve plate 16. The top 25 is formed with two quadrantal openings and it may be integral with the valve box 23 or it may be formed by a separate disc from which the partition 24 depends. The top of the valve box may form a casing for a filter comprising wire gauze stretched upon a perforated cylinder 28 which is held between a cap 29 and a spider 31 by a spring 32 surrounding a nut 33. A stud 17 screws into a boss 14 on the partition 13, passes through a boss on the partition 24, and screws into a nut 26 which is made integral with a stud 27 for engagement by the nut 33. The pump is formed with an inlet 36, and an outlet 37, having a relief valve 34 which may open under excess pressure or be opened by a lever 35 for draining purposes. When no filter is employed, a longer stud 17 extends to the top of the cover 29. Reversal of such a pump can then be effected by re-assembling with the valve plate 16 turned through 180 degrees. In a modification, all the valve stems are arranged on the outer side of the plate 16, and reversal is effected by the mere turning of a handle through 180 degrees, the handle always pointing towards the pump outlet. Fig. 10 shows a power-operated pump which may be reversed during running by providing a reversing valve 55 which co-operates with a ported skirt 58 on a member 56 carrying the partition 57. The outlet valves are mounted in sockets in the member 56, whilst the inlet valves are carried by cored spiders 62 which fit into the inlet ports. The valve plate 63 is formed with a short skirt and a diametral partition 64 which forms a continuation of the partition 13 and is of sufficient depth to allow of full opening of the inlet valves. According to the Provisional Specification, the filter carrier may be bellied, the lip of the valve box may be bevelled to a narrow edge, and the valve plate may fit beneath an interior flange on the valve box.
