Title: Chill mould wall plating system - using currentless plating soln. for cooling grooves and electroplating inside wall
IPC: B22C23/02
Filed: 1979-09-07
Abstract: The walls of chill moulds for continuously cast ingots are treated with plating solutions both on the inside and on the outside along the surface of the cooling grooves. The cooling grooves are plated by passing a currentless plating solution through the gaps between the grooves and a frame plate, with seals between the latter and the boundary ribs of the grooves. The inside wall is plated electrolytically, using an anode which faces the mould wall in an electrolyte container. This produces a good-quality plated coating both on the mould inside to replace metal wear and in the cooling channels to prevent erosion.

Patent DE-2940853-A1 (DE)
Title: Heat powered motor employing curie effect - has heated and cooled ferromagnetic laminations around rotor periphery
Inventor: MUNK HEINZ
IPC: H02N10/00
Filed: 1979-10-09
Abstract: The proposed machine is intended to make efficient use of heat sources having temperatures in the range 40 to 120 degrees Celsius. The rotor (R) consists of a cylindrical disc constructed from ferromagnetic laminations (3) shaped and spaced to give ducts for the passage of the heating and cooling media. The lamination material is chosen to exhibit the Curie effect in the temperature range of interest. The laminations are held by a non-magnetic hub. The stator (S) has sets of magnetic pole pairs (9) evenly spaced around its perimeter. Between each pole set are inlets (8) for the hot and cold media. A lamination set approaching a pole pair is cooled, and magnetic attraction between it and the stator causes the rotor to turn. In the vicinity of the poles hot fluid is introduced and the laminations take on a much higher reluctance and the attraction effects are greatly diminished. At this point, a neighbouring pole pair becomes active to maintain the rotation. The use of laminations gives a higher effective density of active material.

Title: Automatic calendar with year lever, month disc and day disc - has month-end interlock to distinguish between short and long months
Inventor: MERKLE PAUL
IPC: G09D3/08
Filed: 1979-10-22
Abstract: The automatically switching calendar movement comprises a cam disc (1) on shaft (2) which in 31 days rotates 1-1/12 revolutions. This disc has peripheral recesses (b) which are so arranged that, at the end of a 30-day month, a projection (a) of a spring-loaded (11) pivoted (10) lever (9) enters, thereby allowing a disc (3) to be rotated by 1/4 turn. At the February-March transition, the recess (c) is longer to allow 3/4 turns of the disc (3). At the January-February transition, a projection (e) of an annually rotating lever (7) engages a projection (d) on the lever (9), thus preventing the projection (a) from entering the recess (c). The month disc (5) is geared in ratio 12 to 13 relative to the day disc (1).
Patent DE-2944028-A1 (DE)
Title: Constant output pulse amplifier in cordless telephone handset - uses variable amplifier in feedback from comparator reference input
Inventor: KUNDE GERHARD DIPL ING
IPC: H04M1/72
Filed: 1979-10-31
Abstract: The amplifier for received i.r. pulse phase modulated speech signals is extended to make these largely independent from prevailing receiving conditions. The output (SM) of a photoelectric transducer is applied to a variable amplifier (VR) which responds to a regulator (RE) voltage in an inverse proportional sense. The amplified output (PV) is passed partly to a comparator (K01), partly to the non-inverting input of a differential amplifier (K02) which combined with rectifier (GL) and low pass filter (TP) produces a regulator voltage (UR). The same fulfills two functions. By feedback to the variable amplifier it tends to keep the pulse peak output level constant and the comparator output dependent on the setting of a potentiometer (RS) remains at the set level. If, however, the received signal becomes so weak that amplifier VR can no longer attain the regulated level, the second function of the regulator voltage (UR) comes into play in that it lowers the comparator level with which the pulse peaks are compared.
Patent DE-2944707-A1 (DE)
Title: Measures fluid flow and heat transfer in heating installation - using temp. sensors in feed and return pipes of heat exchanger
Inventor: STOESSER KLAUS ING GRAD
IPC: G01K17/08
Filed: 1979-11-06
Abstract: The warm fluid, e.g. water, flows through a feed pipe (1, 2) to, e.g. the heating system, and returns via a return pipe (3, 4). The feed and return pipes are thermally coupled via a heat exchanger (5). The two pipes and the heat exchanger are insulated from their environment. Temp. sensors (T1-T4), e.g. NTC resistors or thermocouples, are located at the inlets and outlets of the two pipes. The temp. (T4) at the outlet of the return pipe is greater than the temp. (T3) at the inlet of the return pipe such that T1>T2>T4>T3. Simple temp. measuring determines fuel consumption of i.c. engine.

Title: Facing sheets bonded to glass fibre reinforced polyester component - esp. sanitary ware with intermediate foam layer of single component polyurethane
Inventor: STAUDENMAYER WINFRIED
IPC: C08J5/12
Filed: 1979-11-17
Abstract: A method of applying sheets or panels, for example of chipboard, asbestos cement or plaster board, onto glass fibre-reinforced polyester resin components, is as follows. The sheet or panel is coated on the side towards the polyester resin component with a coating of moisture-setting, single-component polyurethane resin, opt. diluted; the moisture content of the sheet is higher than the atmospheric humidity and/or the single-component polyurethane resin contains added water, so that once the sheet is applied to the polyester resin component the coating foams and then sets to form the bond. Used esp. for facing sanitary ware such as basins, sinks etc., with a finishing sheet. The method is simple and allows for the natural irregularities in the surface of the basic glass fibre reinforced polyurethane component, since the foam intermediate layer compensates for these uneven features.

Patent DE-3003371-A1 (DE)
Title: Scarcely flammable fibrous material prodn. - e.g. paper, cardboard, paperboard, fibreboard, with addn. of boron mineral and acidification
Inventor: HERR ALFONS K
IPC: D21H27/00
Filed: 1980-01-31
Abstract: In the prodn. of fibrous material, e.g. paper, cardboard, paperboard and fibreboard, from a (vegetable) fibre mat, 3 stages are used (conversion of the wood and other raw materials to half stuff, conversion of this to whole stuff and prodn. of the final fibre mat on endless or round wire machines). Conversion to the whole stuff includes milling the fibres to pulp and addn. of finishing agents. The novel feature is that B minerals (I), e.g. boracite, borax, colemanite, kernite-pandermite, rasorite or ulexite, in finely ground form, are mixed with the pulp, then mineral acid, esp. H2SO4 (96%) or phosphoric acid is added, pref. in the stoichiometric amt. needed for boric acid formation from (I). The pulp is then ripened for ca. an hour before conversion to the end prod. Very good fire retardancy is imparted with little increase cost of the end prod. Ca sulphate is formed in the conversion of (I), which imparts very high strength.
