Title: Heating system with electrically-driven heat pump - has heat pump set in response to external temp. by using two interconnected multiple switches
Inventor: POEHLMANN ERICH
IPC: F24D19/10
Filed: 1979-07-06
Abstract: The heating system has an electrically-driven heat pump or a directly fired absorption heat pump. The cold circulating system of the heat pump is coupled via a heat exchanger to the warm circulating system used for space heating. A first temperature-sensitive switch is thermally coupled to the warm circulation system and has several contact paths set to different temperatures. A second temperature-sensitive switch responds to external temperature and has several switch positions for selecting the contact paths of the first switch depending on the external temperature. The contact paths of the first switch are connected individually to the contact connections of one or more changeover contacts in the second switch.

Patent DE-2928368-A1 (DE)
Inventor: REH LOTHAR DIPL ING DR
IPC: B01J8/18
Filed: 1979-07-13
Abstract: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.

Title: Membrane capacitor pneumatic sensor for low alternating pressure - eliminates membrane mass microphone effect using two coupled sensors
Inventor: MOLDENHAUER KURT
IPC: G01N21/37
Filed: 1979-08-22
Abstract: The pneumatic pressure transducer for measuring small alternating pressure or pressure differences in gas analysers such as infrared analysers working on infrared absorption and using a membrane capacitor eliminates the microphone action of the membrane mass without loss of sensitivity. It consists of two identical pneumatically connected membrane capacitors (1,2) connected electrically in parallel.

The centres of mass of the gas in the pressure sources and membrane capacitors partial vols. both lie in the connecting pipes (5,6). Differential membrane capacitors used to increase the measurement sensitivity. The output leads are connected to a conventional amplifier.

Title: Beneficiating quartz-contg. oxide iron ore - by roasting with reductant and chlorine-source in closed furnace
Inventor: BERTRAM EDWARD FRANK
IPC: C21B15/00
Filed: 1980-08-08
Abstract: The process comprises charging the ore, together with less than 15% (by wt. of ore) of a chlorine source and an excess (w.r.t. iron redn.) of a carbonaceous reductant, into a reaction vessel, indirectly heating the mixt. to max. 950 deg. C, and maintaining the reaction gases in intimate contact with the ore to produce an agglomerate of iron-free ore particles and reductant, bonded together by a matrix of intermeshed fine fibres of mainly metallic iron. Pref. the chlorine source is a metal chloride, and the reductant is coal, coke, charcoal or lignite used in amt. greater than 10% (by wt. of ore). The process is used for concentrating oxidic iron ores with a high quartz content, in which the iron mineral is finely dispersed in the gangue, e.g. Clear Hills ores, Maquette ores and Snake River ores. Chlorine, from the chlorine source, acts as a catalyst for transport of the iron mineral to the surface of theore particles where it is reduced to metallic iron. The resulting agglomerate is relatively easily concentrated, e.g. by magnetic separation, to give a high yield of high grade iron concentrate.
Patent DE-3030310-A1 (DE)
Title: Commutator bar construction for small machines - is fabricated from copper and steel parts welded together and held in insulation moulding
Inventor: KOESTER WALTER
IPC: H01R43/08
Filed: 1980-08-11
Abstract: The bar matches the material to the duty, and also gives a saving in copper usage. The copper for the contact part of the segment is formed as a strip (9) bonded to a steel backing (10). Welded to the steel strip are anchoring lugs (6,7), typically formed from discrete pieces and also of steel. These lugs may be extended at one end to give the electrical contact point (8) for the machine winding ends. The strip assembly is then formed into a cylinder with the anchor lugs on the inside, and the internal space filled with an insulating resin with good mechanical properties. After curing, the exposed strip is slit axially to give the commutator bars. The number of anchoring lugs on any one bar can be selected to suit the mechanical operating conditions. The form of construction allows the material to be matched to the mechanical loading.

Title: Tapering of optical waveguide fibres - by combined use of heating and drawing, where heater is driven along fibre during drawing
Inventor: WENGEL JUERGEN ING GRAD
IPC: C03B23/047
Filed: 1980-09-16
Abstract: A heater is employed to heat a narrow zone of a fibre to its m.pt.; and the fibre is then drawn by a tensile stress applied to at least one of its ends. During the drawing operation, the heater is moved along the fibre; and the speed of travel of the heater, and the drawing speed, are controlled so the desired taper is obtd. The heater pref. travels at a slower speed than the drawing speed, and in the opposite direction to the drawing direction. This sequence of operations is pref. repeated, and the heater moved along the entire tapered zone. Used in optical data transmission, e.g. when a fibre is to be coupled to a laser diode. The end of the fibre must be reduced in dia. to suit the diode. The invention permits the easy prodn. of conical or stepped tapers.
