Patent DE-3011132-A1 (DE)
Title: Mixing head for multicomponent plastics esp. polyurethane - has rotary valve with transverse bore providing widening outlet to mixing chamber but easy cleaning
Inventor: REBERS GUENTER
IPC: B29B7/76
Filed: 1980-03-22
Abstract: The Parent patent described a mixing head for the mixing and discharge of two or more components, esp. in the prodn. of polyurethane mouldings; the mixing head has an elongated, esp. cylindrical mixing chamber, in which a cleaning plunger can slide axially to expel material. At the outlet end there is a rotary valve having a transverse passage through it, which can be oriented at an angle to the mixing chamber in the mixing position, or can be aligned with it for the plunger to clean out the mixing chamber. In this addn. this rotary valve has a continuous transverse bore of the same cross-section throughout as the mixing chamber. At the outlet end of this bore, there is a groove which forms a widened outlet to the bore in the mixing position, but which, when the bore is aligned with the mixing chamber in the cleaning position, is closed by a stationary plug. This plug is so shaped at the end adjacent to the bore that the bore has a continuous cross-section for the plunger to pass through during the cleaning operation. Used for the prodn. of two-component or multi-component materials, esp. polyurethane.

Title: Workpieces coated in fluidised bed sintering appts. - housing bed vessel furnace and raising and rotating equipment all in one transportable unit
Inventor: LEISTNER HANS
IPC: B05C19/02
Filed: 1980-03-24
Abstract: An appts. for coating workpieces, singly or in groups, with powdered plastics uses the fluidized bed sintering method. The appts. comprises a feed station for the workpieces, a heat treatment furnace above this station and a fluidised bed sintering vessel below the station. A vertical transport unit moves the workpieces (7) between the furnace and sintering bed. All these components are integrated into one single, transportable unit, which also contains a rotary device for rotating the workpieces during treatment. Pref., the vertical transporting device consists of a removable frame, in which the workpieces are mounted on a revolving support. The support may be rotated by the meshing of a pinion attached to its shaft with a vertical rack in the frame. Alternatively, the workpiece support may be moved horizontally to engage with couplings driven by an external drive motor. Used for sintered coating with plastics of metal or other components, partic. in small factories. The appts. is a simple, inexpensive unit which can be easily transported to the place of use.

Title: Layer remover for reclaiming screen-printing patterns - sprays liquid onto pattern from set of moving nozzles
Inventor: WEBER ERICH
IPC: B41N3/00
Filed: 1980-05-05
Abstract: The layer remover sprays a liquid onto the pattern or template held by a frame. The liquid is sprayed from nozzles (17) that move relative to the pattern (14) and its supporting frame (13). The nozzles can be switched in and out independently and are supported by a shared beam (16) that slides inside the remover's casing (2). The beam is driven parallel to and backwards and forwards across the pattern, which is stationary inside the casing. The flow of liquid to the nozzles is controlled by valves operated electrically or pneumatically. The remover allows the patterns to be reused.

Title: Heat pump in hot water supply system - uses heat exchanger and water pump in parallel with storage tank for supply control
Inventor: VONHOFF JUERGEN
IPC: F24D17/02
Filed: 1980-06-06
Abstract: The maintaining of hot water supply uses a heat exchanger (2) in a water circulating line in parallel with the hot water storage tank (3). Water in the top part (a) of the tank is kept at a temperature of 50 deg.C and that at the bottom (C) is at 10 deg. The heat exchanger consists of a water filled vessel containing a heat exchanger coil, and is connected to a heat pump (1). Cold water is fed to the heat exchanger, and when a temperature of about 50 deg. is sensed by an element (6) inside the tank, a control unit (5) operates a pump (4) in the line. As the temperature rises, the pumping rate is increased until the temperature falls again. Flow to the tank is continuous, but rises and falls in dependence on the load. An alternative design includes a control valve in series with the pump.

Title: Capacitive instrument transformer
Inventor: SCHAUDT KURT
IPC: G01L9/12
Filed: 1981-06-27
Abstract: The subject-matter of the invention is   a) a method for measuring very small capacitance differences (for example differential capacitor), particularly suitable for measuring pressure by means of diaphragms, but also for other measuring methods in which an electrically conductive plate is moved. The excursion of the plate can be very small. Due to the interconnection according to the invention of a differential capacitor or of two single capacitors, two monostable flip-flop stages and an exclusive OR gate, an output signal is produced, the length of which is proportional to the capacitance difference; b) a method which allows the bending-through of a pressure measuring diaphragm to be avoided and thus to measure independently of its mechanical characteristics. The bending-through is compensated for by electromagnetic forces which are applied according to the invention by two electromagnets attached on both sides of the diaphragm and which operate in accordance with the digital principle, that is to say they consist of a number of individual magnets of different strength which are switched on or off in combination, their switching states at the same time representing the digital measurement signal for the magnitude of the pressure; c) an apparatus composed of a) and b) for measuring minimum pressure differences (e.g. "Warburg manometry").

Title: Circuit arrangement for amplitude-controlled generation of an audible signal
Inventor: HENTZSCHEL H-PETER DR
IPC: G10L13/047
Filed: 1981-07-02
Abstract: For amplitude-controlled generation of an audible signal from stored digital signals, a digital-analog conversion is carried out through changeover of the base current of a bipolar transistor which is controlled with the digital signals, said transistor being connected in series with a loudspeaker. The circuit is also suitable for generating a swell and fade effect and can function with operating voltages of around 1 V due to the current-controlled analog-digital conversion. Particularly advantageous use in integrated systems is therefore possible. <IMAGE>

Title: Pack device for palletising articles and bag goods (automatic palletiser)
IPC: B65G57/24
Filed: 1981-07-25
Abstract: The "pack device for palletising articles and bag goods (automatic palletiser)" which is described uses mutually engaging conveyor systems (Fig. 1) which enter into action alternately and of which the one operating with a conveying direction changed through 90 DEG performs a combined horizontal and vertical movement (Fig. 2) which is achieved by means of oblique planes or suitable lever systems. This permits the smooth and hence energy-saving and ideally gentle combining of groups of the goods to be palletised, primarily bags, to form pack layers. These pack layers are equally gently laid onto the pallet by the use of rolling tracks in the set-down trolley (Fig. 3), so that throughout the entire palletising operation, no adhesive friction forces effect the palletised material at any time. This permits the use of two-layered paper bags and plastic sacks. The upstream installation of a storage belt serves to achieve high speeds throughout the palletisation procedure so that the delivery of the goods (bags) does not need to be interrupted during the movement of the groups formed. <IMAGE>

Title: Brake disc for a disc brake of a motor vehicle, in particular a motor cycle
Inventor: SAGHAFI MEHRDAD ING GRAD
IPC: F16D65/12
Filed: 1981-08-05
Abstract: Brake disc (1) for the disc brake of a motor cycle with four pairs (6) of spokes in which the spokes (6', 6'') converge radially and in mirror symmetry towards the annular disc (7), their axes (a) of symmetry running through the centre (b) of the brake disc (1). The longitudinal centre lines (c) of the spokes (6', 6'') of each pair (6) of spokes on the one hand run through the centre of respective fastening holes (5) associated with the spokes (6', 6'') and on the other hand intersect in the region of the radial extension of the annular disc (7 (at e)). When braking forces act on the disc, the spokes (6', 6'') are subjected to tension and compression and, as a result, only a relatively small number of pairs (6) of spokes is required for the introduction of the braking forces into the attachment hub (2). <IMAGE>
