Title: Apparatus for automatically transferring work-pieces to and from a lathe or other machine tool
IPC: B23Q7/04
Filed: 1957-08-31
Abstract: 851,937. Turret-lathes; feeding blanks. WICKMAN Ltd., DIXON, R. J., and JONES, L. Aug. 19, 1958 [Aug. 31,1957], No. 24309/57. Class 83 (3). An automatic work-chucking turretlathe &c. with horizontal spindles, comprises a shoot 13, 26, down which work 14 is fed by gravity, gating-devices 15, 16, 27, 28, controlling the feed, and a laterally-movable pivoted arm 30 for transferring workpieces singly from the shoot to-and-from the turret. Operations are performed on both ends of the work; and the turret is indexed in steps of 120 degrees. Operations are performed on the first end at stations 1 and 3, work being taken from the chuck at station 5, reversed and placed in the chuck at station 6, and operations on the opposite end carried out at stations 2 and 4. Oppositely-pivoting catches 15, 16, controlled by cams 17, 18, operated by a pneumatic cylinder 20, allow workpieces to fall singly into a section 21 of the shoot, which is pivoted through a rightangle by a pneumatically-operated rack- and-pinion gear 24 to direct the work into the shoot-section 26 extending transversely of the machine. At the lower end of this section the bore of the work is engaged by a gripper 48 carried by the arm 30. Solid-discs may be transferred by a gripper having fingers to engage the periphery of the work. The gripper has a spring-pressed tooth; (Fig. 3, not shown), to retain the work, and may be movably-mounted on the arm by a pneumatic cylinder. Movement of arm 30 along a shaft 31 is by a cam 39 acting through levers 55, 56, which move a collar 33 on shafts 31, 34, arm 30 being rotatable on collar 33 and splined to shaft 31. Rotation of this shaft and thus of arm 30, by a cam 40 acting through linkage 41, 46, swings the work past a pneumatically-operated gating-device 27 to the turret-loading station 5, where axial movement of the arm places the work in the chuck. When the work returns to the loading-station 5 after operations at stations 1 and 3, it is transferred by arm 30 to a reversing-device 77, into which it is stripped by lateral movement of the arm, a spring-catch 79 preventing the work from rolling out of the device. A new workpiece is now transferred by arm 30 to station 5, and the device 77 rotated through 180 degrees by an airoperated rack-mechanism 78 to align its lower end with guide 66, contact between catch 79 and the guide releasing the work, which rolls into the holder 63. The device 77 is then returned to its previous position, and holder 63, with spring-fingers 64, advanced to deliver the reversed work to station 6, the previouslycompleted work having already been removed from the chuck at this station by holder 63 and withdrawn to the mouth of a discharge shoot 68, into which it is rolled through the open end of a guide 66 by rotation of holder 63. This is effected by a cam-slot 76 in the holder-shaft 61 and a pin 75 in a stationary sleeve 62. Axial movement of shaft 61 is by a cam 69 acting through levers and links 70-74.

Title: Data processing system
IPC: G06F12/08
Filed: 1972-05-24
Abstract: 1387043 Data processing INTERNATIONAL BUSINESS MACHINES CORP 24 May 1972 [10 Sept 1971] 24344/72 Headings G4A and G4C A digital data processing system comprises a main memory 9 and processors 1, each processor having its own buffer memory 2 and control unit 6 through which it is connected to the memory. Each control unit 3 is connected to all the other control units, responds to requests from its processor 1 for data not available in the buffer store and transmits such requests to each of the other control units. These are responsive to the requests to determine if a modified version of the requested data is held in their associated buffer and, if so, to transmit the modified data to the requesting processor.  The buffer memories 2 have a higher access speeds than memory 9, and include a cache which stores data and one (or more) directories for address data and validity bits. There is twoway set associative mapping between the buffer and the main memory and the processor may operate on pipelined instructions. Requests for access to the main memory pass to the control unit 6 (Fig. 4, not shown) and a memory busy directory is checked to ensure that the memory area is free. Then a request is selected according to a priority system and transmitted to all the other control units. The requests from the various control units are again examined on a priority basis and one is chosen. The originating control unit then transmits to main storage the selected request to start the memory cycle and, simultaneously, each control unit sends the request to its buffer store. If modified data relating to the requested data is there, it is immediately returned to its control unit which modifies the data in main memory 3. It is also passed to the requesting processor. By this procedure modified data is thus fetched through main memory from a buffer memory without requiring an additional storage cycle.

Abstract: 822,214. Swash plate pumps. INTEGRAL Ltd. Aug. 1, 1957, No. 24431/57. Addition to 820,417. Class 102(1). [Also in Group XXIX] The hydraulic pump of the parent Specification is modified in that the pressure regulating valve 21 is made subject in the direction tending to open it, not only to the reduced hydraulic pressure at the low pressure side of the servo cylinder, but also to the full delivery pressure of the pump. The half-ball valve is mounted in a cup retainer 53 backed by a spring 23, the loading of which can be adjusted by an adjusting screw 54. Pump delivery pressure via conduits 51 and 52 is fed to the top of a pistonlike member 50 in contact with the valve 21, while reduced pressure from the lower pressure side of the servo cylinder is sensed on the exposed upper surface of the valve 21, the two pressures acting together, in opposition to the spring 53 to tend to open the valve.

Abstract: 969,750. Tube joints; screw threads; shaft couplings. ARMCO STEEL CORPORATION. June 21, 1963 [June 26, 1962], No. 24791/63. Headings F2G, F2Q and F2U. A joint for tubular elements, for example well drilling tubing or casing, embodies male and female members 10, 19 having engageable threads of relatively long pitch disposed on a relatively steep taper, with the threads having load bearing and non-load bearing flanks 17, 18, the load bearing flanks having a negative flank angle Z, and the non- load bearing flanks having a positive flank angle of from about 30 degrees to about 60 degrees. The member 10 has full threads and the member 19 has vanishing threads which, when the joint is made up, are engaged throughout their length, and the members have complementary sealing surfaces 12 axially displaced and radially offset from the threads so as to make full conical surface contact throughout substantially their over-lapped length without deformation of either member. The tapered surface 12 on the member 10 terminates in an internal shoulder 11 spaced from the end 20 of the tapered sealing surface of the member 19 when the joint is fully made up and tonged. As shown the flanks 18 slope at an angle of about 45 degreees relative to the axis of the tubing; the angle Z is between 3 degrees and 5 degrees for tubing 2 inches to 3¢ inches in diameter, and is increased to 18 degrees for tubing about 13 inches in diameter. Preferably the flank angle Z of the female member is greater than the flank angle Z of the male member. The conical sealing surfaces 12 comprise threads of a short pitch in relation to the pitch of the threads 13 and which during each make up of the joint are cross-threaded to form a series of minute pockets which trap thread compound to produce a seal and prevent galling each time the joint is disassembled.

Abstract: 1,031,392. Heating granular materials. AEROX Ltd. Oct. 8, 1962 [July 10, 1961], No. 24822/61. Heading F4U. [Also in Divisions A2 and A5] In a method of sterilizing a mineral powder such as talc, or an edible powder such as farina, the powder particles are separated from one another by a gas stream which provides also a sterilizing environment for the particles. In all the methods described, the sterilizing gas is air, and sterilization is effected by heating. In Fig. 1, the powder particles are fluidized and sterilized in a chamber 6 by air which has been previously heated in a heater 5. The air may be recirculated in a line 12 or flow to waste through a filter 2. A supplementary heater (not shown) may be provided in the chamber 6. Temperature measuring points are provided at 8. The floor 3 of the bed is divided into sections in each of which gas flow is regulated, whereby circulation of the powder in the container 1 may be controlled. Other particular methods described are: (a) A fluidized mass of powder particles is sterilized as it flows through a duct 20 containing a heater 22 (Fig. 2, not shown). (b) Powder particles are separated and conveyed on a fluidized conveyer 31 through a sterilizing zone containing a heater 33 or alternatively a heater 34 (Fig. 3, not shown). (c) Powder particles are separated from one another by an air stream which may be preheated. Powder particles and air stream flow in co-current or alternatively in countercurrent over heating coils 41 which maintain the gas at sterilization temperature (Fig. 4, not shown).

Abstract: 599,883. Fluid-pressure servomotorcontrol systems. DELAWARE ENGINEERING CORPORATION. Sept. 25, 1945, No. 24832. Convention date, Jan. 31. [Class 135] In an electrode regulating apparatus for electric arc furnaces in which the electrode 3 is raised or lowered by fluid pressure in a cylinder 6 acting in opposition to the weight of the electrode and its mounting and in which a reversible pump 10 controlled by the flow of current to the electrode is disposed between the cylinder and the fluid pressure source, the pressure at such source is always sufficient to raise the electrode when the pump is not working. The electrode 3 is carried by an arm 4 extending from the piston 5 and is supplied by cable 8 from a power line 7. The pump 10 is driven by a reversible electric motor 20 regulated by a known type of control unit 21 responsive to variations of current in the cable 8. The pump 10 is connected by branch pipes 11a and 15 to a reservoir 12 containing a body of liquid 18. The space above the latter is maintained at a constant pressure by a compressor 17. A check valve 16 prevents liquid returning to the reservoir by the pipe 15 and a check valve 13 permits only inflow into the top of the reservoir. The pipe 11a ends in a spray nozzle 14, whereby liquid returned by the pump is cooled before recirculating through the pipe 15. The pump 10 acts as a metering unit and is incapable of completely blocking the fluid flow. It may be operated as a motor by the fluid pressure in the line.
