Abstract: 925,486. Cam-operated switches; switch covers. GENERAL ELECTRIC CO. Ltd. Jan. 1, 1962 [Jan. 2, 1961; Feb. 23, 1961], Nos. 69/61 and 6672/61. Class 38 (5). A cam 13 for simultaneously actuating two bridging contacts 6 is journalled on a shaft 16 fixed to the base of casing 1. Cam 13 is operated by a handle 15 via a tubular member 17 which is rotatable on shaft 16 and has triangular ends engaging respectively in cam 13 and a plate 26 secured to the handle 15. The handle 15 is journalled in the pressing 19 which, with plate 18, forms a detachable lid for the casing 1. The triangular aperture in plate 26 (for removable engagement with the end of tubular member 17) has recesses (Fig. 3, not shown), which allow free passage of a cross-pin 34 fitted in the end of shaft 16 only when the switch is in the " off " condition. Thus the lid cannot be detached while the switch is " on." A spring- loaded push-rod 29 slidable in a lug 31 is pivoted to the plate 26 to give the handle an over-centre action. Fuse-carriers 9 are provided. In a modification (Figs. 4 and 5, not shown) the handle 15 is replaced by a knob without limited stroke, the push-rod 29 being omitted and a cup-like member takes the place of plate 26 for preventing removal of the lid unless the switch is " off."

Title: Device for coding of n-bits data words into m-bits coded words
Inventor: SCHOUHAMER-IMMINK K
IPC: H03M5/14
Filed: 1985-01-17
Abstract: A method of encoding n-bit information words into a m-bit code words and the other way round is described, which code words have a specific disparity d and a digital sum value which is limited to values p and q. In order to enable encoding and decoding without the use of an extensive look-up table use is made of a series of numbers which is a modified version of numbers in conformity with the Newton binomial. By means of this modified series the n-bit information words, which are arranged in conformity with their binary weights, are mapped lexicographically and unambiguously onto code words with limited digital sum value, and the other way round.

Filed: 1999-05-04
Abstract: The baking device produces endless strips of baked goods from pourable baking dough. A cylindrical baking ring of metal is disposed to rotate about its central axis, while it is supported outside its center. The baking ring has one or more endless baking surfaces on which the strips are produced. A stationary depositing device deposits baking mass onto the rotating baking surface before the baking surface travels into a baking zone. A stationary receiving device removes the at least partially baked strips from the baking ring for further processing. A stationary electrical induction coil is disposed in the baking zone. The induction coil is arranged adjacent the baking ring so that the ring, as it moves through the magnetic field of the coil, is heated by induction for generating heat with which the strips are baked from below.

Abstract: An electrical energy source with a static inverter and a welding transformer 12 for a resistance welding machine comprises a first static frequency converter 10 constructed with semiconductor elements, the output alternating current voltage of which converter has a frequency and a pulse shape which differs from the frequency and the pulse shape of the feed voltage supplied to the inverter. The pulse shape, amplitude and pulse duty factor can thereby be varied within wide limits. This is achieved by connecting at least one other frequency converter 11 in parallel with the first frequency converter 10, in addition to which the output alternating current voltage from the second frequency converter 11 can be added with phase synchronization to the output alternating current voltage from the first frequency converter 10 in the primary circuit of the welding transformer 12. <IMAGE>

Patent DK-81088-A (DK)
Inventor: GLEMET MICHEL
IPC: B29C70/06
Filed: 1988-02-17
Abstract: The present invention relates to a process for producing thermoplastic polymer profiles, reinforced with continuous long fibres, by pultrusion. The process consists, before shaping the rovings impregnated with thermoplastic resin, in compressing the said rovings so as to form a sheet, the elementary fibres of the rovings of which are impregnated with molten thermoplastic resin. The sheet is formed by passing the rovings, after impregnation with thermoplastic resin, into a rectangular heated flat die so as to compress them, thus forcing the molten resin to penetrate between the fibres. The process is applicable to thermoplastic polymers in general, but it also enables a novel profile of polyvinyl chloride reinforced with continuous long fibres to be obtained.
