Abstract: In the case of multipart items of furniture, in particular in the case of tables having a plurality of attached table legs, there is the problem of a simply configured and likewise mountable, play-free and high-strength connecting device between abutting furniture parts, in particular between table leg and table top. To solve this problem there are formed, on the side of a first furniture part (MT1), at least two first fastening members (BFG1a, BFG1b) as toothing elements, arranged at a mutual spacing, with oppositely directed engagement directions (X1, X2) and with load-bearing surfaces (TF1a, TF1b) which are arranged in a mutually opposite manner and parallel or at an acute angle with respect to said engagement directions. There are further provided two fastening elements (BFG2a, BFG2b) having second load-bearing surfaces (TF2a, TF2b), adapted in shape with respect to the load-bearing surfaces of the first fastening members, on separate, second furniture parts (MT2a, MT2b) which can be fitted together and fastened on one another in the engagement direction (X1, X2) of the first fastening members. By simple clamping means (STG), the second furniture parts can be connected to the first furniture part, with bracing of the load-bearing surfaces. <IMAGE>

Patent DE-3140302-A1 (DE)
Inventor: BETHGE KARIN
IPC: H02N11/00
Filed: 1981-10-10
Abstract: In the pulse generator with magnetic polarisation reversal, electric signals are induced in at least one receiver coil (7) by magnetic reversal of a mechanically treated wire (6). The magnetic reversal of the wire (6) is obtained by a relative motion at short intervals of a multitude of magnetic poles (5) having a different polarisation. In order to obtain dimensions as reduced as possible and an accurate initiation of the output signals from the pulse generator, the magnetic poles (5) are at least approximately parallel and the wire (6) is in alignement in the direction of the axis of the magnetic pole (5) so that one end of the wire (6) is exposed to a considerably higher intensity of the field arranged between the poles (5) having curved field lines then the other end. The pulse generator is used appropriately as a control of rotation speed or reference points in an ignition distributor.

Title: Installation for producing castings in boxless sand moulds
Inventor: FISCHER EBERHARD
IPC: B22C11/00
Filed: 1981-10-13
Abstract: The invention relates to an installation which alternately produces the bottom and top parts of moulds, after the insertion of cores assembles them to give a complete sand mould and, after casting, transfers them to a separating or aftercooling device. It is the aim of the invention to provide an installation of this kind which involves less outlay on machinery and control. It is the object of the invention to construct a core insertion stage of any desired length and to construct the casting and cooling stage with just one mould conveyor. This object is achieved by the fact that the mould conveyor assigned to a moulding machine, which swivels mould frames by means of a swivelling device rotatable about a vertical axis out of a station for introducing and compacting the moulding material and into a lifting, closing and ejection station, has a first and a second conveying stage, the first conveying stage running through the lifting, closing and ejection station, the second conveying stage having a feed station and a lifting and turning device corresponding to both the feed station and the lifting, closing and ejection station being arranged between the latter. <IMAGE>

IPC: B01D53/34
Filed: 1981-10-21
Abstract: Method and apparatus for regenerating physically acting organic scrubbing agents laden with sulfur dioxide and/or sulfur trioxide and eventually carbon dioxide in the course of a gas purification process. Equipment costs and energy losses are reduced by adding ammonia and, if necessary, water, to the laden scrubbing fluids and then separating the resultant ammonia sulfite and/or ammonia sulfate. Large differences in temperature between the scrubbing steps and the regenerating steps are not needed. A beneficial energy balance results.

Title: Hinge for doors, flaps or the like
Inventor: GNANN ALFONS
IPC: E05D11/10
Filed: 1981-11-04
Abstract: A hinge for doors, flaps or the like for the closing of a container has a hinge part which is pivotable about an axis and in which an angle lever is mounted pivotably. One of its arms is loaded by compression spring and its other arm carries a roller which is supported on a cam at least partially surrounding the axis and pivotable relative to the hinge part. To provide a hinge which presses the door or lid firmly into its closed position in the closing region only, the cam has a cam region (4'') which is essentially concentric with the axis and on which the roller (9) runs in the opening region. Following this, the cam has in an approximately radial direction a flank (4') on which the roller (9) is supported in the closing region. The lever arms (8', 8'') are so angled relative to one another and have such a length that, when the roller (9) runs onto the flank (4'), the effective lever arm (8''') generating the pressure force is increased. <IMAGE>

Title: Speed safety circuit for controlled-speed series-wound electric motors in hand tools
Inventor: HUBER SIEGFRIED
IPC: H02P29/10
Filed: 1981-11-11
Abstract: A speed safety circuit for controlled-speed series-wound electric motors in hand tools is described which ensures, independently of the normal speed-control circuit, that the motor (1) does not reach unacceptably high speeds in the event of a defect in the control circuit (8) or the associated actuator (3). To this end, the voltage drops on the actuator and on a small resistor connected in the series circuit are monitored by an evaluation circuit (9) which interrupts the current supply, by means of a safety switch (5), if the voltage drops on the actuator (3) and on the resistor (4) are simultaneously less than predetermined threshold values. The safety switch (5) is preferably a temperature fuse, controlled by an additional heating wire (17). <IMAGE>

Title: Central heating system for multi-roomed buildings
IPC: F24D5/02
Filed: 1981-12-14
Abstract: Central heating system for multi-roomed buildings, in which the individual rooms are supplied with fresh air heated by a central air heater via a pipe system operated with high pressure. This heated fresh air forms the driving medium of injector pumps which are arranged in front of the mouths of the fresh-air lines coming from the central air heater into the individual rooms. The flow-off duct of these injector pumps forms the air supply to the respective room, and the suction side of these injector pumps is connected to a suction duct which likewise leads to the room to be heated. Preferably, there is arranged in this suction duct or in the flow-off duct a heating radiator which can be switched on as required.
Patent DE-3201801-A1 (DE)
Title: Method and device for measuring the component sections of the living eye
Inventor: FERCHER ADOLF FRIEDRICH PROF D
IPC: G01B11/14
Filed: 1982-01-21
Abstract: The invention relates to a method for measuring the optical length of the distances between the various optical interfaces of the eye. The method is based on observation of interference phenomena of the light which is reflected or remitted by the eye, illuminated by partially coherent light, at the front surface of the cornea and at the inner interfaces. In order to observe these interference phenomena, the path differences, arising at the eye, of the light bundles are compensated by an interferometer. This can be performed, for example, by a Michelson interferometer, as represented in the figure. The displacement, required to compensate the path differences, of one of the interferometer end mirrors from the basic interferometer position (15' to 15 or to 15") is then equal to the optical length to be measured. <IMAGE>
