Abstract: A carrier (20) for a container package holding an array of cans (C) each of which has an annular bead (B) on the upper end thereof comprising a sheet (21) of flexible plastic material having a plurality of openings (22) forming an array for receiving the ends of the cans and at least one film (23) of plastic material coextensive with the sheet and bonded to the periphery of the sheet. The sheet is made as a coextruded sheet comprising a first relatively thicker layer (21a) and a second relatively thin layer adjacent the film (21 b). The second layer has a melting point lower than that of the first layer or the film and facilitates the bonding of the film to the sheet by heat. In a modified form two layers of film are bonded to the sheet.

Abstract: A control valve (10), in particular for pneumatic deep-hole hammers, has in an outer tube (12) a control housing (15) and, as control member, a flat disc (20) which is movable in an oscillating manner between housing parts (14, 15) possessing air ducts (16). In the housing (14, 15), the disc is supported, so as to be centrally tiltable, centrically by a balancing pin (30) and opposite this by at least one stop pin or stop strip (40). Said stop pin or stop strip plunges into a gap (32), of matching shape, in the pin (30), in which the disc (20) is guided by a web (24) or projections (28) snapping in centrally between apertures (22). The end face of one housing part (14) recedes radially from the central support (30) so that an areal gap (36) with a small gap angle ( alpha ) is formed towards the disc (20). A supporting edge (42), against which the disc (20) comes to bear, is constructed along the tilt axis in particular on the underside of the upper part (13). It is possible to arrange a gap (18) next to the air ducts (16) and a web face (17), in such a way that good sealing between the disc (20) and the housing (15) is achieved. <IMAGE>

Abstract: A method for controlling positioning devices for approaching numerous individual positions (2) arranged in an area (1). In a first step, the individual positions are divided into groups in such a manner that each group (10, 13, 14, 15, 16, 17) assumes a coherent part-area in the positioning plane. The group order is selected in such a manner that the part areas adjoin one another and together form a coarse geometric structure. In a second step, the individual positions are continuously indexed in such a manner that their order follows the coarse geometric structure. In the last step, the indexing of the individual positions is changed section by section in such a manner that the time required for sequentially approaching all individual positions of a section is minimised.

Abstract: An eject header comprises an elongate insulative housing (32) having opposing longitudinally extending sidewalls (34) and transversely extending endwalls (36) and a base (38) supporting a plurality of male terminating posts (42) therein for electrical connection with socket contacts of a complementary connector. The sidewalls (34), endwalls (36) and base (38) define a cavity (40) for receipt of such complementary socket connector. A pair of ejectors (44) are mounted on the housing (32) for pivotal movement in a plane substantially parallel to the endwalls (36) and wherein the ejector lever (44) is manually moveable toward and away from one of the sidewalls (34). The sidewall (34) is formed to have an opening (34a) for receipt of a foot portion therethrough into the header cavity (40). Further, the sidewall (34) is formed to have a sidewall portion(34b) attached to the endwall (36) such that the sidewall portion (34b) intersects the plane of pivotal movement of the ejector lever (44). The attached sidewall portion (34b), in addition to providing structural strength through the header housing (32), serves as a stopping surface for movement of the eject lever (44). By using the sidewall portion (34b) as a stop surface, the throw distance for ejecting the complementary socket connector is enhanced.

IPC: H03B1/00

Abstract: The oscillator comprises a feedback amplifier (10) consisting of an FET (106) and a varactor diode (3) acting as a load-coupling capacitor. A part of the output from the amplifier is supplied as oscillation output to an external load (300) including a high-output amplifier and an antenna device. The varactor diode has a junction capacitance which varies according to the bias voltage applied to the diode. This diode capacitively couples the amplifier to the external load through the variable junction capacitance. Therefore, the capacitance value of the load-coupling capacitor can be changed by adjusting the bias voltage. Thus, the variation of the capacitance of the load-coupling capacitor caused by design errors or by variations of the conditions of the manufacturing process can be easily corrected when the device is in use. In consequence, the oscillator can be operated always with good oscillating characteristics without hindering integration of individual components or a reduction in the cost.

Abstract: La fabrication de rangées de diodes luminescentes (rangées de DELs) dans des imprimantes non mécaniques requiert le montage des DELs (1) dans une position précise sur une plaque modulaire (3). Etant donné qu'une rangée de DELs se compose de plusieurs DELs (1) agencées les unes à côtés des autres, il est nécessaire de les positionner avec précision les unes par rapport aux autres, ainsi que par rapport à la plaque modulaire (3). Les tolérances admises se situent autour de U 3 à 10 mum. Afin d'obtenir un procédé ayant aussi peu d'opérations que possible, tout en assurant un positionnement précis et une manipulation douce des DELs (1), un support auxiliaire est décrit, ayant la forme d'un support suceur (2). Chaque chambre d'aspiration (6) qu'il contient retient par dépression une DEL (1).

Abstract: A method of transforming coordinates of tridimensional laser for transforming the corrdinates of a processing program in a tridimensional laser processing machine. A preprocess calculating means (4) reads a processing program in memory (2) and outputs command values for respective axes. Coordinate transforming means (8, 9) transform these command values into command values on the coordinate system of an actual work in accordance with coordinate transforming matrixes. The coordinate command values thus transformed are interpolated by an interpolating means (11) to output interpolation pulses. These interpolation pulses drive servo motors (21, 22, 23, 24 and 25) to process the work.
