Title: TAchogenerator drive unit - has cover holding signal coil and centred by projections engaging cup recesses
Inventor: MUELLER SIEGFRIED
IPC: H01R39/39
Filed: 1979-06-08
Abstract: Precise alignment of the important functional components of motor for signal processing is ensured by low-cost design. This is achieved by concentric projections of the cover engaging recesses of the cup for centring the bearing's axis. The projections contact the matching recesses in the wall of the cup and can be in the form of radial or axial elements. The assembly prevents inadvertent loosening of the assembly while the cover provides an air gap for the tachogenerator magnetic flux. The cap-shaped cover carries the coil former of the tachogenerator, and the motor features the laminations with a winding and permanent magnets in addition to the magnetically-soft core. The laminations and winding are supported by a shaft in bearings held by a cup and flange.

Title: Molten aluminium-silicon alloys treated with sodium - by tablets contg. sodium fluoride and maintaining sodium content of melt during long casting periods
IPC: C22B21/06
Filed: 1979-07-17
Abstract: The alloy is first treated with a conventional agent (a) providing sodium; and is then treated with tablets (b) contg. a mixt. of alkali halides and free carbon, where the mixt. contains sufficient NaF so its m.pt. is above the temp. of the molten alloy. Tablets (b) maintain the % Na in the melt at a desired level over long periods of time. Mixt. (b) pref. contains by wt. 40-60% NaF, esp. ca. 50%, and 3-20%, esp. ca. 12% free carbon. The tablets (b) are pref. added after agent (a) has been consumed, or are immediately placed on the surface of the alloy and maintained there until the end of casting. Sodium is added to prevent the pptn. of large Si crystals, but agents (a) are only effective for max. half hour. In gravity die casting, the molten alloy needs to be held for a much longer time in a furnace; and the invention (b) maintains the % Na during long times.

Title: Ion exchanger resin regeneration control - by resistance sensor comparator actuating LED
Inventor: FISCHER KLAUS ING GRAD
IPC: B01J49/85
Filed: 1979-07-20
Abstract: The regeneration of the ion exchanger resin in a water softening plant, for example for a dishwasher, is controlled by a reference resistance sensor in the fresh water inlet to the ion exchange tank, and a resistance sensor in the top third of the resin. The latter is temperature-compensated by an NTC transistor. A light-emitting diode indicates the time for regeneration. Resistance electrodes and an indicator supervise the salt level and the brine concentration. This provides a reliable indication both for the spent state of the ion exchanger resin and for the residual level of indissolved common salt in the salt container.
Patent DE-2931610-A1 (DE)
Title: Adhesive plaster - with embedded heating element and pocket for button battery
Inventor: LANDSRATH WALTER
IPC: A61F13/00
Filed: 1979-08-03
Abstract: An adhesive plaster consists of a rectangular strap, with the two outer ends adhesive and the middle part lined with muslin. An electrical heating wire is embedded in zigzag fashion in the muslin and its ends are exposed bare in a small flap pocket above the middle part. If a small button battery is inserted in this pocket, the wire is heated and warms the skin around the spot of application. This is a safer way than using heat generating ointments which may have undesirable side effects.

Title: Temperature level raising process - dries air by heat exchange with medium in heat pump circuit
Inventor: STREICH MARTIN DIPL PHYS
IPC: F24F3/14
Filed: 1979-08-09
Abstract: The process raises the temperature level of heat using a heat pump circuit in which a medium is compressed, cooled, liquefied, expanded, and evaporated by heat-exchange with air. The air is dried by the heat-exchange process. Before this, part of the air can be dried and mixed with undried air, and air drying can take place in the regenerated one (5b) of two driers (5a,5b). For regeneration of the loaded drier (5a), air can be heated by heat-exchange with part of the compressed medium, passed through the loaded one, cooled, freed of condensate and mixed with the air to be dried.

Title: Central heating system with open fireplace - has overheating safety control with additional parallel stand-by water heating system
Inventor: MEYER AXEL E CHR ING GRAD
IPC: F24B1/18
Filed: 1979-08-21
Abstract: The safety unit is esp. for use with open fireplaces, supplying a central heating system. The heating system has a parallel stand-by water heating system, with heat exchanger coils. During high ambient temperatures, the central heating system is switched off, and one or more stand-by water tanks or similar consumers are switched-on to act as return controls. When a max. water temperature has been reached, a heat sensor element switches on the control heating system and when this has heated up, a continuous heat exchanger is actuated. This produces stand-by water for immediate use, or feeds it into an additional storage tank.

Title: Flue gas outlet for solid fuel boiler - is preceded by baffle plate to slow speed and lower temp. of flue gases
IPC: F24H9/00
Filed: 1980-06-18
Abstract: The boiler has a horizontal double-wall cylinder enclosing its combustion chamber. The space (11) between these two walls forms a water jacket. The flue gas outlet (15) is at one end, near the top, and inside the inner wall (20) is a baffle plate (16), bent so as to control the flow of the combustion gases towards the outlet. The end of this plate is stepped, with a vertical face (162) connected by a horizontal face (161) so that the gas flow is slowed down sufficiently to lower its temperature. This improves the efficiency and reduces soot formation. The leading part of the plate is parallel to the inner wall, and the vertical face is D-shaped. In an alternative design, the inner wall and the baffle plate incorporate flanges which alternate with each other, forming a zig-zag discharge path for the flue gases to improve the effect still more.

Title: Compressed movement scanner for photocopier - has two sets of lenses with relative orthogonal movement
Inventor: MINOURA KAZUO
IPC: G03B27/52
Filed: 1980-07-04
Abstract: An optic scanner for a photocopier has two sets of lenses (4,5) whose relative positions w.r.t. the main optic axis are continuously varied during the scan. This compresses the lateral movement of the scanner without affecting the resolution or the magnification and provides a simple drive. The scanner uses low angle of scan. The system provides a conjugate image (3) between the main subject plane (1) and the second lens (5), with this plane and the final image plane conjugate w.r.t. each other. The speed of each lens orthogonal to the main optic axis is related to the magnification and the actual scan rate.
