Patent DE-3126690-A1 (DE)
Title: Extraction device for the extraction and cleaning of contaminated air
Inventor: WARLIS ROLF
IPC: B08B15/00
Filed: 1981-07-07
Abstract: With the extraction device according to the invention, contaminated air, in particular spray mist, can be extracted and cleaned. The extraction device consists essentially of a housing (1) which has a suction surface (3) on its front side, and of a cover cowl (2) which covers the suction surface (3) (Fig. 1). By means of the attachment of a cover cowl (2) in front of the suction surface (3), the sucked air is diverted so that air suction can take place from all sides. Compared with conventional extraction devices, there is the advantage that improved all-round extraction takes place. In addition, with the extraction device according to the invention, the volume of air extracted can be adjusted for various suction directions. Thus, for example, the suction power in the base region can be increased by enlarging the lower air gap (8) between the cover cowl (2) and the housing (1). <IMAGE>

Title: Sintered magnetic alloy of the Fe-Cr-Co type and process for producing articles with such an alloy
Inventor: YAMASHITA MICHIO
IPC: H01F1/08
Filed: 1981-09-09
Abstract: A sintered magnetic alloy of the Fe-Cr-Co type with contents of essentially 20 to 35% of chromium, 3 to 15% of cobalt and a remaining content of essentially iron, and a process for producing articles from such an alloy are proposed. The process comprises the stage of mixing at least Fe-Cr powder and Fe-Cr-Co powder with a carbonyl iron powder and, if appropriate, a cobalt powder - if the latter is necessary to obtain the alloy composition - for preparing a powder mixture, the average particle size of the Fe-Cr powder and of the Fe-Cr-Co powder being 200 mesh or smaller, and the surface of these powders being activated. As the next step, pressing of the powder mixture to give a blank is proposed. The blank obtained is then sintered in an atmosphere with a total content of oxygen and nitrogen of less than 3 ppm. Finally, a heat treatment and magnetising treatment of the sintered alloy obtained can be carried out. <IMAGE>

Title: Process and device for the individual separation of springs
Inventor: TURNER HERBERT ELLERY
IPC: B65G47/32
Filed: 1981-10-24
Abstract: A process and a device for the individual separation of helical springs are described. The device has a first conveyor (2), onto which packaged springs (S) are placed. The springs are moved by the conveyor in a transverse position up against a stop (8) which can be retracted out of the path of movement of the springs and which interacts alternately with a separating wedge which can likewise be advanced into the path of movement of the springs and retracted from this. As a result of the sluice-like functioning of the stop (8) and of the separating wedge (9), the springs detached from the spring pack by the latter are fed individually to a fixedly held magnet (11), where they are picked up individually by a second conveyor (12) and conveyed further. The device is capable of replacing the hitherto necessary manual work involved in the individual separation of prefabricated bundled helical springs before their further processing. <IMAGE>

Patent DE-3211752-A1 (DE)
Inventor: HIEBER KONRAD DIPL PHYS DR
IPC: H01L21/285
Filed: 1982-03-30
Abstract: Structured layers composed of high melting point metal silicides, such as tantalum silicide, are selectively deposited on substrates having at least some silicon and some non-silicon regions, such as are used in thin-film and semiconductor technology, by thermal decomposition of gaseous silicon and halogen compounds containing a high melting point metal in a reaction gas and depositing the metal silicide onto the silicon regions of the substrates while providing a gaseous hydrogen halide, such as hydrogen chloride, to the reaction gas and adjusting the substrate deposition temperature and the composition of the reaction gas to values at which a silicide nucleation in substrate regions, other than silicon regions, is suppressed during deposition of the metal silicide from the gaseous phase due to the presence of the hydrogen halide. The invention is useful for producing contact track levels in VLSI circuits.

Title: Pushbutton switch lock with an exclusive switching position
Inventor: BUEHL HERM DIPL-ING
IPC: H01H27/06
Filed: 1982-07-02
Abstract: What is described is a pushbutton switch lock having a first contact set, the switching positions of which can be set by means of a key which can be inserted into the lock through a slot in a pushbutton. By means of this pushbutton, a second and a third contact set can be actuated in specific switching positions. One of these switching positions can be set only with a special key, but not with the normal key suitable for the other switching positions. For this purpose, a tumbler of the normal key is designed so that a blocking element projects from the lock cylinder and moves in a blocking recess extending over the switching positions admissible for the normal key and located in the lock body. This blocking recess does not extend into the switching position which is reserved only for the special key and for the setting of which the tumblers of the special key are designed so that all the blocking elements are aligned with the lock cylinder. <IMAGE>

Title: Device for preparing for packing chocolate-coated cream cakes (chocolate whirls) or similar pressure-sensitive products
IPC: B65B35/44
Filed: 1982-09-09
Abstract: The device for preparing for packing a predetermined number of chocolate-coated cream cakes into compartmentalised cardboard packaging material or the like comprises a production belt which supplies the cakes, and a "switch-off group" (A), which is formed from a number of conveyor belts and always keeps ready a reserved space for receiving the cakes. Rapid and reliable transport of the cakes through the device from the "switch-off group" (A) is to be achieved by the sequence of an inclined vibrating grid (5), a turntable (6), conveyor belts (10) which can be switched off individually and are arranged between parallel guide rails, longitudinally adjustable conveyor belts (12), and a delivery table (spring table (14)) which can be moved by a feed cam (84). Rapid and reliable group formation of the cakes is to be achieved by means of transverse stops (11 and 13) which, as a result of being controlled by light barriers, can be lowered downwards. To ensure that a container (20) is always presented at the right time for delivery by the spring table (14) of the cakes, the delivery station, which is situated above the frame piece (122), is in each case lowered after it has been fed so that the container (20) can be moved underneath the spring table (14). <IMAGE>
