Patent DE-3505956-A1 (DE)
Title: Container for receiving an audio tape cassette
Inventor: DEERBERG ROLF
IPC: G11B23/023
Filed: 1985-02-21
Abstract: A container, comprising a housing (11) and a drawer (12) guided displaceably therein, for an audio tape cassette is to be designed in such a way that a removal of the audio tape cassette without hindrance is possible while minimising the dimensions of the complete container, and it is similarly possible to assist the opening movement of the drawer by an energy storage mechanism. For this purpose, the drawer (12) is provided in its bottom region with a central section (16) which can be swung downwards in relation to the remaining bottom surface (17) and on which the front wall (15) of the drawer (12) is also formed. In the opened state, the central section (16) swings downwards to the extent that an audio tape cassette located in the drawer (12) can be removed without hindrance parallel to the plane of the bottom (13) of the housing (11). The opening movement of the drawer (12) is assisted by a energy storage mechanism, for example in the form of a spring clip (22). The overall dimensions of the complete container correspond to the original packaging of an audio tape cassette. <IMAGE>
Patent DE-3510681-A1 (DE)
Title: Rotary compressor
IPC: F04C18/344
Filed: 1985-03-23
Abstract: The rotary compressor is fitted with an eccentrically mounted rotor, and the vanes 5, 6 facing one another and disposed in slots of the rotor form a rigid assembly, i.e. vanes facing one another are solidly and rigidly linked to one another. As a result, the centrifugal forces acting on the vanes are compensated, so that higher rotational speeds are possible without adverse effects. Even for low rotational speeds, sufficient sealing is ensured, as the vanes bear on the wall of the casing bore at all times. <IMAGE>

Title: Installation frame for bordering a cutout and for engaging around a removable covering
Inventor: ROTH ECKART
IPC: E04F19/08
Filed: 1985-12-18
Abstract: The invention relates to an installation frame (3) for bordering a cutout (2), included in a fixed surface, in particular of a building, and for engaging around a removable covering (9) for this cutout. There is at least one magnetic holder (11) present having a permanent magnet (18) which is located opposite the covering (9), as seen from the rear side of the frame, and fixes said covering by magnetic force. The permanent magnet (18) has a central cutout (20) which is directed at right angles to the plane of the frame and into which there engages a magnetic core (21) consisting of magnetisable material. Changing its position relative to the permanent magnet (18), said magnetic core (21) can be screwed in and out and, in this arrangement, can be screwed, by its front end directed towards the covering (9), in front of the permanent magnet (18). <IMAGE>
Patent DE-3545316-A1 (DE)
Title: Bill carrier and process for fastening a bill on the same
Inventor: MIESNER SIEGFRIED
IPC: G09F15/00
Filed: 1985-12-20
Abstract: With bill posts (10), there is the danger that the bill (17) will become detached over time as a result of wet weather, and this is the case, in particular, for a (new) bill post (10) which is provided with a bill (17) for the first time. In order to prevent this, the invention proposes that, before attaching the bill (17), a layer of plain paper be drawn over the carrier layer (15) located therebeneath and comprising old bills or a first bill stuck on the concrete surface of the casing (11) of the bill post (10). The netting is designed, for a bill post (10), as a tube (16) of netting which mechanically holds the carrier layer (15) adhering only lightly to the concrete of the bill post (10), with the result that the bill stuck onto the carrier layer (15) and the tube (16) of netting can undergo optimum paper/paper adhesion on an underlying surface firmly connected to the bill post (10). With adhesion of this type, there is no longer any danger of the bill post (10) falling down, even in wet weather. <IMAGE>

Title: Impeller for an eccentric spiral pump
Inventor: BECKSCHULTE JUERGEN
IPC: F04C2/107
Filed: 1986-02-14
Abstract: The invention relates to an impeller for an eccentric spiral pump. It consists of alloyed steel. Its core is to be elastic in order that it withstand the torques arising during operation. Its surface must, however, be resistant to abrasion, in order that the impeller has on the whole a long life. In the impeller according to the invention, the core therefore consists of an elastic material which withstands turning and torsion strains and, applied on this, an abrasion-resistant layer made of a hardened abrasion-resistant alloy.

Title: Method and device for immobilising a stationary vehicle
Inventor: LOKNER MARIJAN
IPC: B60T7/12
Filed: 1986-03-22
Abstract: In a method for immobilising an idling and stationary vehicle, especially a motor vehicle, in one or in both directions of travel and/or with a direction of travel selector lever, especially a gear, engaged, a movement measuring device (2) for detecting the stationary condition of the vehicle and a direction of travel measuring device (5, 6) are provided, the values of which are fed into a computer (3). When the vehicle is stationary and the direction of travel measuring device (5, 6) is in the neutral position, the vehicle is immobilised by means of an immobilising device (9-17), in both directions of travel if it is possible for it to move in two directions or in one direction of travel if the vehicle is only able to move in that direction. If the movement measuring device (2) registers a stationary condition and if a certain, pre-selected direction of travel is registered, the opposite direction of travel is immobilised by the direction of travel measuring device (5, 6). <IMAGE>

Title: Cooling device on a tool holder of a machine tool
Inventor: BERGER ZOLTAN
IPC: B23Q11/10
Filed: 1986-05-24
Abstract: Cooling device on a tool holder of a machine tool for uniformly cooling the tool from its shaft to its tip. For this purpose, coolant is fed under pressure to the interior of the tool holder via a hole. The said coolant emerges at end-side slots on the tool holder, said slots being present between the clamping jaws, and the coolant flows as a surge along the outer wall of the tool to the tip thereof. In this way, the coolant flows all around the tool and the tool is considerably better cooled than if the coolant is only fed to the tip of the tool. As a result, the tool can continue to have a large degree of dimensional accuracy and mass production with constant quality using an automatic lathe is possible. <IMAGE>

Patent DE-3640199-A1 (DE)
IPC: B65D83/14
Filed: 1986-11-25
Abstract: The aerosol container has two separate chambers (11, 12) for different components (A, B) which are to be mixed during use, the two chambers (11, 12) being arranged one above the other and being connected to each other by a connection channel (21), which can be opened during use, in such a way that the opening of the connection channel (21) can be produced by mechanical movement of the chambers (11, 12) relative to each other, and a discharge valve (13), which can be actuated independently, being assigned to the upper chamber (11). In order to be able to construct the lower chamber more easily, the latter is filled with a first component (A), in particular hydrogen peroxide, and a first propellant (T1), in particular butane, propane or the like, and the upper chamber (11) is filled with a second component (B), in particular hair dye or the like, and a second propellant (T2). Said propellant (T2) causes a smaller pressure, which is sufficient for discharging the component mixture through the discharge valve (13), inside the upper chamber (11) than the propellant (T1) in the lower chamber (12). The purpose of the latter propellant is merely to press the first component (A) out of the lower chamber (12) into the upper chamber (11), mixing it with the second component (B), when the connection channel (21) which is common to both chambers (11, 12) is opened. Finally, the connection channel (21), consisting of only three plastic components, is also of importance. <IMAGE>
