Title: Automatic apparatus for the production of movable contacts for electromagnetic relays
Inventor: GIORDANINO PIERO
IPC: H01H11/04
Filed: 1987-03-11
Abstract: A strip (12), in which a succession of contacts (1) has been prepunched, is fed to a first operating unit (10) for intermittently stopping the strip (12). A second operating unit (16) feeds contact points (5) to a fourth operating unit (20) for moving the points while a third operating unit (18) checks whether the points have been correctly deposited in appropriate seats arranged in the fourth unit (20). A fifth operating unit (24) lifts the contact points (5) to facilitate their pickup by a sixth unit (22) which, as it shifts, transfers the points into holes (4) provided in the contacts (1) on the strip (12). A seventh operating unit (26) rivets the points while a lifting device (28) lifts the strip (12) after this riveting operation. An eighth operating unit (30) gauges by a pressing operation the points that have been riveted by the preceding unit (26) while a ninth unit (32) advances the strip (12) by predetermined stepwise movements. The described apparatus is particularly useful for high output of movable contacts. <IMAGE>

Title: Knitting machine control
Inventor: THOMPSON NIGEL VAUGHAN
IPC: D04B15/66
Filed: 1989-04-27
Abstract: A memory (18) has memory locations corresponding to each of a plurality of needles of a knitting machine, each of which memory locations may be accessed via input means. As shown, each pixel of a VDU (14) corresponds to a respective one of the memory locations and is scanned at 16 to provide signals which are stored at 18, when the knitting machine carriage reaches a first point cam PI on a track 12 of needles, a start signal is generated and the stored signals are read to control the knitting process. By this means, each of the needles of the knitting machine may be selectively manipulated so as to produce at least one unrepeated pattern along the width of the knitted material. The VDU (14) may be coupled to a video camera to produce an image which is to be reproduced by the knitting machine. The memory may also store information as to the particular colour of a given stitch and the machine may include a yarn unit adapted to hold a plurality of coloured yarns and to present the appropriate colour yarn for the next stitch. <IMAGE>

Title: Prevention of DC saturation of current transformers in electricity meters
Inventor: FIELDEN JOHN SPENSLEY
IPC: G01R11/24
Filed: 1989-05-02
Abstract: In a static electricity meter, the cosine component of the second harmonic I100 of the load current I is used (12) as a controlling parameter to introduce (13, M) a DC flux into the secondary (N) of the current transformer (11) so as to effect cancellation of the DC load flux. A further embodiment (Fig 7 not shown) incorporates adaptive variation of the flux regulating current in such a way that the detected value of the required 50Hz component of load current is maximized. In Fig 6 (not shown) DC flux cancellation is achieved without using an additional winding (corresponding to M, Fig. 5). The registration accuracy of the meter is thus maintained despite the presence of fraudulently or accidently introduced asymmetric consumer loads containing DC current components that would otherwise saturate the transformer and thus desensitize the meter to energy registration. <IMAGE>

IPC: B29C44/56
Filed: 1990-02-01
Abstract: A method of altering the resilient properties of plastics foam sheet material comprises crushing the material to a reduced thickness and releasing the crushing pressure to allow the foam to recover to a thickness smaller than the original thickness. The foam may be crushed between two platens of a press, or by passing it between two rollers. It is also possible to form shaped sheets of foam material by placing sheet between two platens, bringing the platens together to crush the foam material, and simultaneously cutting the foam material by means of blades projecting from one of the platens to form a shaped sheet. The crushed sheet material is suitable for use as cushioning material in packaging.
