Title: Improvements in or relating to electromagnetically-actuated reciprocating pumps
IPC: H02K33/10
Filed: 1947-02-05
Abstract: 638,362. Reciprocating motors. BENDIX AVIATION CORPORATION. Feb. 5, 1947, No. 3429. Convention date, Feb. 11, 1946. [Class 35] [Also in Groups XXVIII and XXXVII] An electrically-actuated pump comprises a piston 2 of magnetic material sliding on a cylinder 1 of non-magnetic material and is moved in the delivery stroke by a spring 25 and on the suction stroke by a solenoid 43. The current to the solenoid 43 is controlled by contacts 53, 56, the contact 53 being stationary and the contact 56 being carried by an armature 58 pressed by a spring 59 to the bottom of a cylinder 54 of non-magnetic material surrounded by a solenoid 62. The magnetic circuit of the solenoid 62 has a gap 64. The solenoid 62 is energized continuously, but the flux is not sufficient to close the contacts 53, 56 until the gap is closed by the piston 2 when nearly at the end of its stroke under the influence of the spring 25. In a modification, two gaps are provided in the magnetic circuit and so arranged that the contacts are closed when the piston has bridged one gap and almost bridged the second and are opened when both gaps are not bridged. The Specification as open to inspection under Sect. 91 comprises also a switch arrangement shown in Fig. 6 (Cancelled), in which one contact 77 is fixed to a casing 71, that partly surrounds the pump cylinder and is filled with inert gas, and the other contact 75 is carried by a lever 73 pivoted at 74 and carrying a permanent magnet 79. When the pump piston is adjacent the magnet 79, the contacts 75, 77 are closed. This subject-matter does not appear in the Specification as accepted.

Patent GB-687152-A (GB)
Title: Improvements in conveyor mechanism for transporting materials in bulk
IPC: B65G43/00
Filed: 1950-02-13
Abstract: 687,152. Control of several motors. MITCHELL, F. G. Oct. 20, 1950 [Feb. 13, 1950], No. 3660/50. Class 38 (iii) [Also in Group XXX] Bulk material is transported by a single conveyer from a selected one of a plurality of supply sources, appropriate respectively to different classes or grades of material, to means at the delivery end of the conveyer for directing the material selectively along one of a plurality of routes appropriate respectively to the different classes of material, under control of means for selectively determining which class of material shall be fed at any given time and for selecting the corresponding route to be taken by the material at the discharge end of the conveyer. A single transport conveyer 7 is fed by three hoppers 1, 2 and 3 selectively and discharges selectively into three hoppers or bunkers, 9, 10 and 11, in accordance with variations in the levels of material therein. As each hopper 1, 2 or 3 is filled to the top from waggon tipplers a level switch 12, 14 or 16 is closed, and as each hopper or bunker 9, 10 or 11 is emptied into transport vehicles a level switch 13, 15 or 17 is closed. Closure of either switch 12 or 13, 14 or 15, 16 or 17 completes a circuit through corresponding relay 24, 25 or 26, which operates a pilot motor 18, 19 or 20. Each pilot motor M, Fig. 4, drives reversibly a screwed rod 32 in order to traverse a nut member comprising a contact 34 over a number of contacts 35-39. Contact 35 causes a directing conveyer 8 at the discharge end of the conveyer 7 to be appropriately positioned either as shown in the case of pilot motors 18 and 20, or moved transversely in the case of pilot motor 19, so that conveyer 7 can feed hopper 10. Contact 36 similarly starts up conveyer 8 in the appropriate direction in the case of pilot motors 18 and 20. Contact 37 then starts up conveyer 7 and contact 38 starts up a feeding conveyer 4, 5 or 6 appropriately such that pilot motor 18 causes material to be transported from hopper 1 to bunker 9, motor 19, from hopper 2 to bunker 10 and motor 20, from hopper 3 to bunker 11. When contact 34 reaches contact 39 the drive to screwed rod 32 is reversed so that in the time allowed for complete transference of material from a hopper to a corresponding bunker contact 34 returns over contacts 38, 37, 36 and 35 so as to stop the conveyers in turn and finally stop the pilot motor. In the case of a hopper 1, 2 or 3 becoming full or a bunker 9, 10 or 11 becoming emptied while the conveyers are operating and one pilot motor is in operation, the other pilot motors are prevented from operating by means of cut-out relays 30, 31 coupled across pilot motor 18 and similar relays (not shown) across the other two pilot motors.

Title: Improvements in and relating to the Release Valves of Hydraulic Accumulators.
Inventor: SCHNEIDER EUGENE
IPC: F15B13/04
Filed: 1916-03-11
Abstract: 104,237. Schneider, E. March 11, 1916. Volume-regulating valves.-In valves for regulating the flow of water from hydraulic accumulators, the main A from the accumulator is provided with a Venturi-tube 1 leading to the valve box E fitted with a piston valve F. The valve spindle also carries a piston P working in a cylinder Q, the piston and valve being normally pressed upward by the external spring R. The two ends of the cylinder Q are connected by pipes L, M to the full and reduced diameters respectively of the Venturi-tube. When the flow of water is normal, the valve is in its highest position, but when the velocity increases the excess of pressure above the piston P moves the piston down and partly closes the valve F. The rate of descent of the accumulator ram is thus regulated, and at the bottom of its travel the part B striles the lever 0 and closes the valve, so that the accumulator is prevented from striking its bed.

Title: Improvements in means for regulating the focus in x-ray apparatus
IPC: H01J35/14
Filed: 1926-02-10
Abstract: 247,568. Liebermann, M., (trading as Muller, C. H. F. [Firm of]). Feb. 11, 1925. [Convention date]. R÷ntgen-ray tubes.-In a tube having an incandescent cathode, the area of the focal spot is automatically regulated in accordance with the current between the electrodes, by means of a focusing device connected directly to the cathode and of a cathode-ray disperser which is connected to the cathode through a resistance producing a potential difference. In one arrangement, the disperser consists of a rod 15 projecting through the centre of the cathode, which is in the form of a conical spiral attached at one end to the focusing shield 14. A resistance 10 is inserted between the filament-heating transformer circuit and the high-tension supply transformer, to which the disperser 15 is directly connected. In another arrangement the filament is a helix extending along a slot in a trough-shaped focusing device, and the disperser is a wire parallel to the axis of the filament and within the trough. The Specification as open to inspection under Sect. 91 (3) (a) mentions the use of a transformer instead of the resistance and also describes a third form in which the filament and focusing shield are similar to those first described, but the disperser is a ring situated between the electrodes and connected directly to the positive side of the high-tension transformer, between which and the anode a resistance is inserted. This subject-matter does not appear in the Specification as accepted.

Filed: 1953-02-11
Abstract: A preparation for the treatment of cancer &c. is obtained by treating metochondrial animal material selected from the liver, kidney or heart in such a way that the enzymes are liberated, and dialysing the disintegrated material to obtain a dialysate containing the co-enzymes of the succin-oxydase system having a particle size smaller than 10 m .  Thus, liver is frozen, finely ground and dried in vacuo, the powder is stirred with a fat-dissolving organic solvent, e.g. butanol-1, filtered, and the residue dried.  This is mixed with water or physiological salt solution, and dialyzed using a membrane of pore width 5-10 m  against water or physiological salt solution at 0-2 DEG  C. Concentration may be effected by dialysing new starting material against a dialysate already prepared.  The preparation may be sterilized by ultrafiltration in vacuo.  The operations generally, and storage, are effected under nitrogen.ALSO:A preparation for the treatment of cancer &c. is obtained by treating initochoudrial animal material selected from the liver, kidney or heart in such a way that enzymes are liberated, and dialyzing the disintegrated material to obtain a dialyzate containing co-enzymes of the succinoxydase system having a particle size smaller than 10m .
