Abstract: 891,658. Turning inside out. HALL (TEXTILES) Ltd., B. P., and HALL, W. H. July 8, 1960 [July 8, 1959; May 19, 1960], Nos. 23399/59 and 17635/60. Class 112 [Also in Group VIII] A rotatable hose-inspection form contains a passage which extends into a chamber and ends at, and spaced from, the mouth of a delivery tube extending from the chamber to a delivery point, and means are provided to produce an air stream first along the passage and then through the delivery pipe. A form 1 is mounted on a rotatable tube 2 which is journalled in a bracket 4 fixed to the side of a table 5 and ends within the conical mouth of a delivery pipe 7 which enters a chamber 6 carried by the bracket 4. The other end of pipe 7 is supported by a bracket 8 above the table top and is closed by a counterweighted flap valve 20. A pipe 10 connects chamber 6 to a port 11 in a valve casing 12. Ports 13 and 14 in the latter are connected by pipes 16 and 17 to inlet and outlet sides respectively of an air blower. A valve 18, controlling said ports, is connected to a treadle 19. Valve 18 is normally so set that air is extracted from chamber 6, valve 20 preventing admission of air to pipe 7. When a stocking on the form is released, it travels toe foremost down tube 2 and stops at tube 9. Treadle 19 is then operated to blow air into chamber 6, when the stocking travels along pipe 7 and is deflected by the partly-open valve 20 on to the table top. It is stated that the arrangement can be combined with the extendible form described in Specification 801,937, bracket 4 then being in the form of a cylinder, and the piston associated therewith being connected to the stocking-extending members. The delivery pipe may discharge alternatively into a receptacle. The delivery pipes of two or more adjacent forms may discharge into a common delivery pipe.

Title: Stable smallpox vaccine
IPC: A61K39/285
Filed: 1962-06-20
Abstract: A stable smallpox vaccine is prepared by blending vaccinia virus infected tissue with a substantially neutral aqueous suspension medium, treating the resulting blend to effect mechanical separation of relatively large particle of cells and debris while leaving the vaccinia virus in suspension, adding an antibiotic or mixture of antibiotics to the thus clarified virus suspension and allowing antibiotic activity to proceed for at least one day, treating the antibiotic treated virus suspension to effect a mechanical separation of vaccinia virus from the antibiotic solution, resuspending the thus separated vaccinia virus in a substantially neutral aqueous suspension medium and freezing said virus suspension.  The infected tissue is preferably calf pulp.  Phenol to a concentration of not more than 0.5% w./v. is added to the virus suspension, preferably at a stage prior to separation of the virus from the antibiotic-containing solution. The frozen vaccine may be vacuum dried or it may be thawed.  The antibiotic may be penicillin, streptomycin, chlortetracycline, oxytetracycline, bacitracin, tyrothricin, chloromycetin, or a mixture of polymyxin B sulphate, neomycin sulphate and dihydrostreptomycin, which is preferred.  The separated vaccinia virus may be resuspended in a neutral aqueous suspension medium containing a water-soluble or water-dispersible therapeutically acceptable and injectable extender, e.g. peptone, polyvinylpyrrolidone, dextran, albumen, vegetable gums, animal sera and sugars such as sucrose and lactose.  The preferred suspension medium is an aqueous phosphate citric acid buffer of pH about 7.2.

Title: Data Processing System with Access Control for Subsystems
IPC: G06F13/18
Filed: 1967-05-23
Abstract: 1,174,069. Interruption data processing. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23876/67. Heading G4A. A data processing system comprises a memory controller operable to store a plurality of programme interrupt requests, and cause an interrupt in response to the highest priority stored request, and comprising means to receive and store interrupt mask signals, from a processor, which correspond to selected interrupt requests to be inhibited, to prevent granting of such stored interrupt requests Input-output controllers and processors can each communicate with each of a plurality of memory controllers each associated with a respective memory. Each memory controller accepts a 16-bit word and a command code from the highest priority controller or processor attempting to communicate with it. The command code is decoded to pass the word into memory (at an address also specified by the communicating controller or processor), or use it to set selected flip-flops of one of two groups of 16 interrupt flip-flops, or use it to set/reset the flip-flops of one of two groups of 16 mask flip-flops. One mask flip-flop corresponds to each interrupt flip-flop. As long as any interrupt flip-flop corresponding to a reset mask flip-flop is set, an interrupt request present signal is sent to a processor selected by manual or programme - controlled switches. When the processor reaches an odd-numbered instruction with bit position 28 equal to 0, during or at the end of its current programme, it sends a command code to the highest priority memory controller which is currently supplying an interrupt request present signal. This command code causes the identity of the highest priority interrupt flip-flop which is set and which corresponds to a reset mask flip-flop, in the memory controller, to be encoded and sent to the processor to constitute part of the address portion of the next instruction, the interrupt flip-flop then being reset. The rest of the address portion of the instruction is fixed in accordance with the identity of the memory controller. The non-address (command) portions of the instruction are provided by fixed circuitry. This instruction causes the processor to access memory at the address specified by the instruction to enter another programme. Information about the interrupted programme (if the prior programme was interrupted before completion) is stored to allow subsequent return to it. Each input-output controller may set interrupt flip-flops in only one memory controller specified by manual or programmecontrolled switches. Nand and inverter logic, including junctions at which a 0 will override any 1, is described for determining the highest priority unmasked interrupt flip-flop in a given memory controller, and for generating the interrupt request present signal.

Abstract: 1514211 Hydrostatic transmission control C VAN DER LELY NV 5 June 1975 [17 June 1974] 24337/75 Heading F2W In a hydrostatic transmission control for a tractor, winch or crane wherein the displacement of a variable displacement swash-plate pump 1 in closed circuit with a variable displacement swash-plate motor 2 is normally adjusted by a follow-up servomotor control system 3, 12, 13, a pedal operated inching valve 6 connected between the displacement adjusting servo chambers 12, 13 provides fine adjustment of the pump displacement. The inching valve 6 comprises a tapered valve spool 62 which, when depressed against the bias of a spring 64, provides a throttled connection between the chambers 12, 13 to effect a reduction in pump displacement proportional to valve depression. The pump displacement is normally adjusted by a lever 7 which acts through a rod 44 and springs 49, 50 on a floating lever 33 which is connected at its ends to a srvomotor control valve spool 42 and to an arm 32 fast with the pump swash-plate 20. Movement of the lever 7 acts through the rod 44 and lever 33 to adjust the position of the valve spool 42 to a position in which it supplies pressure liquid from an engine driven pump 5 to the servo chamber 13 or 12 for forward or reverse drive respectively. The resulting movement of the pump swash plate 20 acts through the arm 32 and lever 33 to return the valve spool 44 to its "null" position. The pump displacement is thus proportional to the movement of the lever 7. The lever 7 is held in an adjusted position by a pawl and ratchet. The motor displacement is adjusted by a similar follow-up servomotor system.
