Patent GB-2220648-A (GB)
Title: Tamper-evident container
Inventor: STENHOUSE LESLEY
IPC: B65D55/02
Filed: 1989-07-12
Abstract: A tamper-evident container includes indicia on a closure member and container body which are in register in the initial sealed state; at least one of the indicia is substantially invisible to the naked eye but is capable of being viewed by subsequent treatment thereof. In the preferred embodiment two U.V. lines 10 are provided respectively on a cap 11 and body 12 of a container and are aligned (Fig. 1) when the container is sealed closed. Since the lines 10 are normally invisible, if the cap 11 is unscrewed, the probability is that the lines 10 will no longer then be coincident. When exposed to U.V. radiation the lines 10 will become visible indicating that the container may have been tampered with. The indicia may alternatively be made by a heat-sensitive ink dye. <IMAGE>

Patent GB-2224971-A (GB)
Title: Collet for a hydraulic clamping system of a high-speed hydraulic press
Inventor: BIELFELDT FRIEDRICH BERND
IPC: B30B1/32
Filed: 1989-10-17
Abstract: A high-speed hydraulic press has a press ram 5 which is releasably gripped by a collet 3 in order to lock the press ram 5 to a piston 2. This brakes the press ram 5 and the press ram/piston combination 5, 2 then moves together at slow speed. A diaphragm 7 positioned around the collet 3 is pressurized with hydraulic fluid in order to make the collet 3 grip the press ram 5. If hydraulic fluid leaks out of the diaphragm and gets between the collet 3 and press ram 5, it will take the collet 3 longer to brake the press ram 5. This may lead to localized overheating and cracking of the hydraulic fluid. To prevent this from happening, O-ring seals E, F are provided to block the leaking fluid and a bore 17 is provided in order to drain the fluid away.

Title: Welding gun apparatus
Inventor: KAWADA MASAKI
IPC: B23K11/31
Filed: 1992-03-02
Abstract: In a DC type C-shaped welding gun apparatus a centre tap (5b) of the transformer (5) is communicated to a movable gun arm (3) via an ounce metal plate (11). A rear end portion of a stationary gun arm (4) is pressingly held between a pair of terminal plates (5c, 5c) via rectifiers (6). Both terminal plates (5c, 5c) are disposed such that their centre line is offset to one widthwise side of the transformer (5). The stationary gun arm (4) is thus disposed to one widthwise side of a projected area of the transformer (5). The ounce metal plate (11) for supplying electric power to the movable gun arm (3) is disposed to the other side of the projected area. In an X-shaped welding gun apparatus, a first gun arm (103) is rotatably supported by a supporting shaft (102) provided on a gun bracket (101). A second gun arm (104) is directly connected to one of feeder terminals of a transformer (105) to combine the second gun arm (104) and the transformer (105) into a unit. This unit is rotatably supported by the supporting shaft (102) via a supporting arm (110), and the other of the feeder terminals is connected to the first gun arm (103) via the supporting arm (110) which is used as a feeder member. The feeder member can thus be disposed within the width of the gun bracket (101). The vacant space around the transformer is utilized as a space for disposing the operating cylinder (113) to thereby minimize the size of the welding gun. <IMAGE>

Title: Memory utilisation for data processing
Inventor: BRENNAN JOHN
IPC: G06F9/46
Filed: 1992-12-24
Abstract: A data processing system carries out in-line verification of received data. At step 23 writing to a history file is carried out in parallel with steps 24 - 27 in which a relevant data record is accessed, processed. The history file has a very large number of discrete data records each of which has an address corresponding to the relevant data record. Printing of a document for a data record involves retrieval of all data from both data records and working file records and merging of the data. On the other hand, printing of a general report involves accessing the data records only. The address for the records is made up by a series of numerical sequences, each relating to a parameter. This leads to versatility and efficiency in sorting operations. <IMAGE>
