Title: Method for recovering heat from the waste gases of a burner-heated heating appliance and device for carrying out this method
Inventor: BEIGEL GOETZ
IPC: F24D12/02
Filed: 1988-07-12
Abstract: The waste gases of a burner-heated appliance are guided, together with the stale air of a heated space, through a heat exchanger (1) and cooled by fresh air in the countercurrent. The size of the proportion of the heat exchanger impinged by the waste gas is regulated as a function of the waste-gas temperature, i.e. increased with rising temperature of the waste gas. The heat exchanger (1) which is exchangeably inserted into a housing (2) is supplied, on one side via separate inlets (3 and 4, respectively) of the housing (2), with a mixture of a proportion of the waste gas capable of being regulated by means of a pivotable flap (6) and of room air and, on the other side via an inlet (9), with fresh air to be heated in the counter current. <IMAGE>

Patent DE-3826710-A1 (DE)
Title: Vacuum pump
Inventor: ABE TETSUYA
IPC: F04D19/04
Filed: 1988-08-05
Abstract: The invention relates to a vacuum pump for use in a nuclear fusion plant. The vacuum pump according to the invention comprises a multiplicity of vacuum pump units which are each encapsulated individually in casing blocks and, by means of their casing blocks, are inserted in a common outer casing. The individual vacuum pump units can be designed for different evacuation rates, so that the pump according to the invention is optimally adapted to the load requirements at any particular time. As a result of the multiplicity of pump units, the diameter of the impeller blades, made of brittle ceramic material, of the turbomolecular part can be kept relatively low, so that the risk of said blades being destroyed is correspondingly low. If such destruction should nevertheless occur, the encapsulated embedment of the vacuum pump units in question prevent adjacent pump units from being adversely affected. The outer casing in this case ensures that any radioactive gas which may be present in the destroyed pump unit cannot escape into the environment. Advantageously, provision is further made for the voids in the pump, for example between the outer casing and the individual encapsulation casings, to be filled with a coolant liquid such as water, which, at the same time, serves as an irradiation protection jacket. <IMAGE>

Title: Apparatus for the infeed of a grinding slide on a gear-grinding machine working by the generation method with indexing control
Inventor: BERNAU UWE DIPL ING
IPC: B23F23/00
Filed: 1988-12-13
Abstract: The object of the invention is to mechanically superimpose the infeed movements for width crowning on the electronically controlled infeed movements of the grinding slide. The object is achieved according to the invention in that an auxiliary slide 7 driven by an eccentric 10 is allocated to the grinding slide 3 moved by an NC actuating drive 5. The drive of the eccentric 10 is initiated by a template device which deflects the pivoted lever 12 by an angular amount and thus adjusts the auxiliary slide 7 and the grinding slide 3 by an indexing amount e, which is indicated by the displacement measuring system 9. The value x is retained unchanged in the process. <IMAGE>

These cobalamin conjugates, for example the conjugate of the formula
 B12-d-CO-NH-NH-CO-CH2-(O-CH2-CH2)3-O-CH2-CO-NH-N = PODox, are very suitable for use in immunoassays, especially for the determination of cyanocobalamin.

Title: Vehicle window antenna
Inventor: SAKURAI KAORU
IPC: H01Q1/12
Filed: 1989-03-28
Abstract: A vehicle window (1) is provided with a broadcast radio antenna (9) and a window heater (5). Laminated glass is used, which comprises inner and outer sheets of glass which face the inside of the vehicle on one side and the outside on the other side. The heating conductor (5) is fitted on a first surface of the laminated glass. At least a part of the antenna conductor (9) is located on a second surface.

Title: Balance control of welding tongs which open linearly or rotationally - magnetic or friction brake is used to provide accurate balance in all positions of tongs
Inventor: SCHWOB FERDINAND
IPC: B23K11/31
Filed: 1989-08-19
Abstract: One of the arms of the welding tongs is moved linearly or is pivoted to open and close the tongs. The tongs are closed on the workpiece by a drive unit acting against the effect of a brake which acts on the moving electrode with a force corresp. to the wt. of the tongs. When the welding force is developed the welding current is switched on. When welding is completed, the drive unit is reversed and moves the tongs away from the work until it strikes a stop, whereupon the brake force is overcome and the upper electrode returns to its initial position. The brake may comprise magnetic metal rod attached to mobile  electrode, to which a force is applied by a fixed electromagnet supplied with an electric current corresp. to the wt. of the welding tongs. Or friction brake may be used. The brake may be disengaged during welding. USE/ADVANTAGE - Used for regulating the bal. of the elements of a welding tongs. System is superior to existing spring-loaded and pneumatic-cylinder balancing devices i.e. provides balancing of the tongs in all its positions and is not influenced by the dynamics of the tongs motion.

Filed: 1989-11-14
Abstract: The iron comprises an electrically heated soleplate (3), the desired temperature of which is controlled by a thermostat (5) by the said thermostat periodically interrupting and restoring the power supply. The thermostat (5) can be set by means of an adjusting element (19). The iron is provided with a first and a second indicating element (23, 25), with in each case two indicating states (activated/non-activated). The indicating elements (23, 25) provide information on the actual temperature reached with respect to the desired temperature set.
