Title: Staking tool
IPC: F16D3/41
Filed: 1979-09-21
Abstract: A staking tool adapted for use in the repair of a Hooke's type universal joint. The tool comprises a body (40) formed from hexagon bar and having six longitudinally extending corners (41) parallel to its longitudinal axis and each slightly flattened. The corners extend to an end face (42) of the body and the body is cut away on a radius at the junction or each corner and this end face to provide a sharp corner (43). In use, the tool is driven into a bore and the radius formations (43) move material of the bore forwards and thereby form inwardly extending projections or stakes in the bore. <IMAGE>

Patent GB-2088083-A (GB)
Title: Optical fiber switch
IPC: G02B6/35
Filed: 1981-11-23
Abstract: Switching between optical fibers is achieved through the use of a fixed (101) and movable (102) housing disposed within a slotted support member (103, 205). The fixed and movable housings respectively contain first (104, 105) and second (108) sets of optical fibers. Each housing has two grooved (204) and parallel exterior surfaces. Both housings are disposed in substantial abutment to one another in the slotted support member with the both sets of optical fibers parallel to one another. The sidewalls of the slot are grooved to be the mating opposite of the grooved housing surfaces. The first housing is fixedly positioned in the slot by the mutual engagement of the grooved exterior housing surfaces and the grooved sidewalls. Switching between optical fibers is accomplished by the translation of the movable housing surfaces to either of two positions which axially align a predetermined number of optical fibers in the first and second sets. Each position of the movable housing is precisely determined by the engagement of one grooved exterior housing surface and one grooved sidewall. <IMAGE>

Patent GB-2093399-A (GB)
Title: Hydraulic press
IPC: B30B15/06
Filed: 1982-02-22
Abstract: A hydraulic press (15) provides rapid advance of one platen (35) on a movable crosshead (36) through the use of programmed hydraulic controls and is specifically adapted for use with sheet molding compound (SMC) presses. Rapid locking or latching of the crosshead (36) and the platen (35) it carries to columns 17 is achieved through the use of hydraulically operated clamping and release cylinders (54). The lower platen (72) is supported on hydrostatic bearings permitting the platen to move and at the same time parallelism of mold halves (30, 31) is maintained by swivelling molding power cylinders (75). Separate push-back cylinders (95) are used to separate the mold halves through a short load path so that when the mold "breaks away" there is a very little springback to minimize any part breakage during mold stripping. The lower platen (72) also includes a mounting arrangement that provides the advantages of a rolling bolster or lower platen with a minimum of mounting structure. The control permits accurate rapid molding of plastic sheet parts in particular, which require high controlled force, closely controlled mold movement and operation at elevated temperatures. <IMAGE>

The memory comprises up to 8 boards connected in parallel, the Figure showing one board. Each board comprises four memory modules 512, 514, 516, 518 which can be accessed in overlapping manner since the memory cycle of a module is 400 ns against 100 ns for the buses 318, 320. Each module comprises two memory banks 520, 522 each with 21 16 K memories each arranged as a 128 x 128 bit array. The 16 K memories are addressed in parallel by row and column address latches 526, 528 whereby each bank stores 16 K 21 bit words. For memory access the row and column addresses RA, CA are supplied to the latches 526,528 from MEMIN bus 320 and a buffer 534 while six bits BMS supplied to memory logic 538. These bits select the board which is to perform a memory operation, the module within the board and the bank within the module. Readout is from the selected module via a multiplexer 540 and one of four registers 542, 544, 546, 548 catering for overlapping accesses. For a write operation, the word to be written is transferred from MEMIN bus 320 to a data latch 365 before the addresses RA, CA and select bits BMS are supplied as described above.   <IMAGE>

Title: Dry type continuous wire drawing process and machine
Inventor: ASAKAWA MOTOO
IPC: B21C1/02
Filed: 1983-06-17
Abstract: A dry type continuous wire drawing process and machine 20 which can enhance productivity by conducting in- line a wire drawing operation, including the steps of flaw detection and wire repair. The wire 11 to be drawn is mechanically descaled using a descaling unit 26 and is then coated with a lubricant. The wire thus coated is drawn through a drawing die 38. At the coating step, the wire is first coated with lime powder in a bath 28 and then with metallic soap in baths 30, 32. After the drawing operation, any flaw in the surface of the wire is detected by a flaw detector 40. The position of such a surface flaw is identified from the running speed or distance of the wire and the detecting instant. Any such surface flaw located is removed by a flaw remover 42 if possible. The resultant wire is wound up on a take-up roller 44. Any surface flaw which cannot be removed is marked. An internal defect in the drawn wire is detected using ultrasonic waves. The internally detected portion is also marked. All of these steps are conducted in-line. <IMAGE>

Title: Vehicle controls and instrumentation
Inventor: ALCOCK KEITH
IPC: B61C17/12
Filed: 1984-08-08
Abstract: A locomotive operator's seat 10 is pivotally mounted about a pivot arrangement 18 whereby the seat 10 may be moved to face more towards either one of two opposed intended directions of travel of the vehicle. Mounted on the seat are instrument pods and vehicle controls for controlling gear change, brakes, throttle and headlights. Two microswitches 46 in the region of the pivot arrangement are able to alter some of the instruments, or the function of some of the controls when the seat is moved from facing more towards one direction to facing more towards the other. An operator is able to pivot the seat while being located on the seat by pulling a knob 44 to release a plunger which otherwise locks the pivot arrangement. That plunger is only able to lock the seat in a plurality of positions in each of which the seat faces more towards either direction of travel (i.e. the seat is not able to be locked sideways on to the direction of travel). In an alternative arrangement (not shown) when the seat faces the side of the vehicle the controls are rendered inoperative. <IMAGE>
