Patent DE-3535717-A1 (DE)
Title: Balancing device, in particular for abrasive wheels with any desired position of the axis
Inventor: KLEMM WERNER DIPL ING
IPC: B24B41/04
Filed: 1985-10-05
Abstract: The invention relates to a balancing device, to which balancing medium is fed selectively in a plurality of chambers from a control device and in which, for reactivation, each chamber has a drainage device. The aim of the invention is to shorten the reactivation time under conditions of minimum destructive loads on the spindle and bearings and minimum effort for the reestablishment of the balanced condition.   In accordance with the object, reactivation is performed during rotation by the emptying of the chambers, while maintaining the approximately balanced condition. According to the invention, the drainage devices of all the chambers are formed by respective non-return valves with a closed position subject to spring force or centrifugal force, each non-return valve is assigned a mechanical release device, and all the release devices can be actuated by a contactless actuator. <IMAGE>
Patent DE-3538917-A1 (DE)
Title: Container
Inventor: SIRCH MANFRED
IPC: B65F1/12
Filed: 1985-11-02
Abstract: A container (10) has a flap (20) at the bottom which is held in the closed position by a locking claw (22). The locking claw (22) is prestressed by means of an opening force which, however, remains inactive while the container (10) hangs freely since the flap (20) holds the locking claw (22) in the locking position. A loaded container is emptied by being set down, hanging on a crane, onto an unloading surface, as a result of which the flap (20) pivots upwards and thus releases the claw (22) which, in turn, swings into a release position by means of a spring (36). The container can now be lifted, in which case the flap (20) gradually pivots downwards and empties the container contents. <IMAGE>

Patent DE-3608933-A1 (DE)
Title: Stoma bag
Inventor: KROACK JOSEPH
IPC: A61F5/441
Filed: 1986-03-18
Abstract: The invention concerns a stoma bag for reception of the intestinal contents emerging from an artificial intestinal outlet, the stoma. The stoma bag (1) has a device, in single or double configuration, for the odourless discharge of the resulting intestinal gases. The device comprises a cartridge-like container (5) which has a perforated wall and is inserted in a receptacle (4) of the stoma bag (1) and contains the pre-filter (10) of a highly permeable filter material. This pre-filter (10) is connected via a line (13) to the main filter (15) which is also designed as a tube-shaped or cartridge-shaped container (14). In the area of inlet and outlet of the intestinal gases flowing through it, the main filter (15) contains a fine filter material (17) and an absorption or adsorption means (18) located between these. The arrangement and design of the pre-filter and the main filter keep moisture away from the absorption or adsorption means, so that it remains permeable to intestinal gases, permits high throughput of gas and results in reliable neutralisation of the gases. <IMAGE>

Patent DE-3624918-A1 (DE)
Inventor: GUTU-NELLE ANCA DIPL ING
IPC: C03B19/09
Filed: 1986-07-23
Abstract: A method of making optical waveguides is disclosed in which, to fabricate a preform, glass forming pulverulent material is filled into a mold by means of one or more screw conveyors. The quantity of glass forming pulverulent material filled into the mold per unit of time is increased by passing a suitable gas through the apparatus. Thus, the quantity conveyed per unit of time can also be controlled by adjusting the gas pressure. By using a dry gas, the moisture content of the powder can be reduced.

Patent DE-3640271-A1 (DE)
Title: Method and device for measuring speed and acceleration
Inventor: BECK ARMIN
IPC: G01P15/16
Filed: 1986-11-25
Abstract: The invention relates to a method of measuring speed and/or acceleration by video recordings of the moving body or from the moving body. In the process, in each case time and displacement distance are also recorded so that value pairs for displacement and time can be read off during single-frame viewing. The speed and acceleration can be determined from these value pairs. By means of a suitable device the time can be slotted into the frame and held on the video tape. During single-frame viewing, it is then only necessary to read off the instants at which the moving body has reached certain displacement marks or immediately transmit them to a programmed computer.

Title: Crossed roller bearing
Inventor: HERRMANN ALFONS
IPC: F16C33/50
Filed: 1988-02-29
Abstract: The invention relates to a crossed roller bearing in accordance with Patent Application P 3629173.0-12 with a cage strip (11) for the alternate arrangement of cylindrical rollers, in which chambers (12) are provided essentially in the longitudinal sector to accommodate the cylindrical rollers (3). In addition, the walls of the chambers are provided in the direction of the bearing surfaces (10) of the rollers with essentially opposite openings from which the bearing surfaces of the rollers partially project. Of particular advantage here is that the upper opening (in each case in the direction of installations) are designed as larger introduction openings (13) which allows the rollers to be snapped in, while the lower openings serve as guide openings (14) for the rollers. The rollers are thereby guided and held accurately and the end friction of the rollers is thus eliminated. <IMAGE>

Title: Typewriter or office machine of similar design with a paper guide
Inventor: EHBEN ALFRED
IPC: B41J13/10
Filed: 1988-04-07
Abstract: In order to be able to easily read the text which has already been typed on the paper sheets (8) still located in the machine and to be able to detect the end of the paper sheet (8) in good time, a paper guide (6) with a sheet-end display (11) is required.

Title: Peristaltically operating diaphragm pump
Inventor: KOPP FRANZ OTTO DR ING
IPC: F04B43/02
Filed: 1988-04-21
Abstract: The invention relates to a peristaltically operating diaphragm pump from the generic type of machines operating with a flat diaphragm. The machine according to the invention has a number of slides, at least 3, which move up and down, of which the central slide is preferably of circular-cylindrical shape and around which the other slides are arranged so as to annularly enclose the central slide and thereupon one another successively and so as to guide one another in the sense of permitting the sliding movement constrained by transmission means, the slide which lies furthest out and encompasses all other slides also being guided in the housing in this sense. A respective slide, when it is situated in its upper stroke limit position, presses the diaphragm in an annular contact line against the inner face of the indentation of the pump cover, this contact line lying in a plane perpendicular to the sliding direction and perpendicular to the direction of the press-on force. The diaphragm is moved owing to the movement of the slides in the form of an annular wave which advances radially, preferably from the outside inwards, the wave crests contacting the inner face of the pump-cover indentation, while applying a respective press-on force. The clamping edge of the diaphragm between pump cover and pump housing is exposed to only one of the two pressure zones, preferably the pressure zone of the inlet.

Title: System for reducing the risk of fire spreading
Inventor: BLUECHER HASSO VON
IPC: A62D1/00
Filed: 1988-04-30
Abstract: A mixture, which still flows easily, of water and gel particles which are contained in the water and themselves are over 99 % composed of water is sealed inside envelopes and deposited at points which are to be protected against fire. For example: thermal insulation of roofs of industrial buildings. In the event of fire, the envelope bursts, allowing the mixture to exert its extinguishing effect. The water contained in the gel particles does not flow away and prolongs the cooling effect by evaporating in a controlled manner.
