P through a circuit incorporating a relief valve 7, a check valve 8, a manually-controlled valve 3 and a pressure-responsive control device 20, as shown. The valve 3 includes check valves 31, 57, 61 and a manually-operable slide valve which controls ports 34, 36, 37 arranged in the circuit as shown, the port 34 being in permanent communication with the port 33. The device 20 is a three-way valve which connects the feed conduit 14 with the branch conduits 21 or 19 when the pressure is less than or exceeds a given value respectively. The arrangement is such that at top and intermediate speeds all the pressure fluid is passed through a single motor section or two sections respectively, the valve 3 being disposed as in Figs. 2 and 3 (not shown) respectively. Again, at slow speed, part of the pressure fluid passes through the circuit in Fig. 4 (not shown), whilst at stop all pressure fluid passes through the circuit in Fig. 5 (not shown). Controlled lowering is effected with all circuits in throttled communication with the discharge (see Fig. 6 (not shown), and reversa is effected with all the pressure fluid being fed in the opposite direction through a single motor circuit (see Fig. 7, not shown). In a modification, an additional motor, Fig. 10, is connected in the circuit of the device described above as in Fig. 9 (not shown), and is brought into operation under the control of a pressureresponsive valve 81. The motor incorporates three chambers 204, 205, 206 having individual inlets 207, 208, 209 respectively, a common outlet 210 for two chambers and a separate outlet 211 for the third chamber. The inlet chamber 102 of the valve 81 may communicate with either its outlet chamber 103 or the feed conduit 80 according to the setting of the valve proper 111. Specification 774,315, [Group XXIX], and 777,231 are referred to.

Title: Improvements in and relating to operating mechanism, applicable for example, to electric circuit breakers
IPC: H01H71/50
Filed: 1937-11-19
Abstract: 490,641. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 19, 1937, No. 31907. Convention date, Nov. 19, 1936. [Class 38 (v)] Operating mechanism comprises an actuating solenoid having a reciprocally operable plunger corrected by a flexible linkage to a member to be actuated reciprocally movable in a direction generally transverse to the direction of plunger-movement, a pivoted element including a roller coacting with the flexible connection for guiding and restraining the same along a path of changing direction, actuation of the solenoid effecting a pull on the connection to move the member in one direction, and trip means for releasing the member so that the resulting slack in the connection permits reverse movement of the member. The Figure shows the application to a trip-free switch the switch member 4 of which, when stripped, is opened by a spring 21. The plunger 2 of the solenoid 1 is connected to member 4 by a flexible chain 3 which is guided round a roller 8 on a bell-crank lever 5. The far end of 5 carries a roller 11 which is normally held in the closed position shown by a lever 12 having a trip arm 14 which is rotatable on a shaft 13 by a trip-solenoid 15 or manual trip-lever 18. When the solenoid 1 is de-energized, the plunger 2 is retained by a spring-controlled prop 22 pivoted at 23. The bisector of the angle between the two parts of the chain 3 is offset by the distance a from the pivot 6 of the lever 5, so that when the latter is tripped the spring 21 rotates it clockwise, and the chain 3 collapses. A surface 5<1> on lever 5 then engages an extension 26 on prop 22, so moving it clear of the plunger 2, which is then raised by a spring 27, and allows a spring 28, tensioned during the opening movement, to restore the lever 5 to reset position. The breaker is reclosed by energizing the solenoid, and is retained by the spring 24 producing re-engagement of 22 with a pin 25, on the plunger 2, the pin being guided by plates 25<1>.

Abstract: 1,012,085. Mechanical seals. SEALOL Inc. Aug. 7, 1964 [May 25, 1964], No. 32164/64. Heading F2B. Sealing means for controlling the leakage of pressure fluid along a rotary shaft, e.g. a pump shaft 18, where it extends through a housing 10 comprises an axially floating piston 50 which surrounds the shaft and has an annular sealing face 54 co-operating with a sealing face 28 on a sealing ring 27 fixed to the shaft, the piston being axially movable between the ring 27 and a disc 25 fixed to the shaft under the action of a fluid pressure differential acting on pressure surfaces 55, 56, 57 and 101 of the piston to thereby control the space between the sealing faces 28 and 54 and thus the amount of leakage occurring. The piston is sealed to the housing 10 by an 0-ring 42. The areas of the faces 55, 56, 57 and 101 and that of the face 54 are arranged so that in operation the faces 28 and 54 are separated by about 0À0001 inch and the passages A and C between the disc 25 and the face 56 and between the ring 27 and the face 55, respectively, have widths of approximately 0À009 inch and 0À0002 inch, respectively, and are both restrictive to fluid flow. In a modification only the passage C is restricted. The piston may be urged toward the ring 27 by a spring. In the modification shown in Fig. 8, the piston 50A is connected by a metallic bellows 75 to a collar 33A fixed to the housing 10 and rotation of the piston is prevented by a pin 76 which engages a slot 77 in the piston.

Abstract: 1520819 Protein hydrolysate H J ROBERTSON 3 Aug 1976 [10 May 1976] 32302/76 Heading C3H A therapeutic agent comprises a non-antigenic protein hydrolysate containing polypeptides and amino acids obtained by: commingling the feet of young freshly killed poultry or the feet of other young freshly killed animals (other than human beings) with a dilute organic acid solution containing 1-1À5% by weight of acid at an elevated temperature up to 155‹ F., removing the fat constituent and removing the solubilized protein and dissolved minerals at the elevated temperature. By the feet of young freshly killed poultry or the feet of other young freshly killed animals (other than human beings) are meant feet of poultry and animals that are sufficiently young that the resulting protein substantially lacks antigenic properties and that the feet are in prime or undeteriorated condition. The said poultry feet may be obtained from chickens not more than 9 weeks old whilst the organic acid is preferably acetic acid. The poultry feet may be ground and pretreated with an organic acid at 70-90‹ F. The fat removing step preferably includes cooling the solution and separating out the fat layer. The agent may be in the form of a dehydrated gel which is obtained by reheating the cooled solution, after removal of the fat, and subsequently air drying the reheated solution. Alternatively the agent may be a powder which is obtained by spray drying the resultant solution from which the fat material has been removed. In an Example specific percentages of the following aminoacids, as making up the material of the invention, are specified: Asp, Glu, His, Lys, Arg, HLys, HPro, Thr, Se, Tyr, Gly, 2Cys, Pro, Al, Va, Met, leu, ileu, Phe.

[Also in Division F4] Apparatus for measuring fluid-flow along a pipe comprises fluid velocity head measuring means mounted in a pipe section through which the fluid flows, a constriction in said section and means for measuring the fluid-pressure drop across the constriction. In the measurement of the flow of pulverized fuel through a pipe 1 the velocity head in a pipe section 2 inserted in the pipe is measured by a manometer (not shown) connected differentially to a pipe 7 projecting diametrically into the section 2 and a pipe 12 terminating at the section wall. A manometer is also provided to measure the pressure differential existing between the interiors of Piezometric rings 15 and 18 connected to apertures 13 and 16 at the entrance and throat, respectively, of the Venturi 3. This differential pressure is dependent upon both rate of flow of air and the content of entrained fuel, whereas the velocity head is dependant solely upon the rate of flow of air. Thus by calibration of the manometers the fuel content in the air flow may be obtained. In an alternative embodiment a number of tubes 7 each with an associated tube 12 are employed, the tubes 7 and 12 being connected to separate Piezo-metric rings. The invention may be utilized for controlling the supply of solid fuel to a pulverizing mill for entrainment in an air stream and carrying to a burner (see Division F4).
