Filed: 1980-06-25
Abstract: Process for metering the flour and/or liquid (s) in the kneader (61-63) during the production of dough as well as an installation for implementing such method. The component to be metered is determined, during the processing, by means of a central control device (3); the weight corresponding to the desired dose is calculated for the component. Then, the component is conveyed, from the weighing container (1, 40-42, 46) along a conveyor line (5, 7: 49) towards the kneader (61-63), through valves (58, 60) controlled by the central control device. The valve opening time is controlled by the central control device (3), as a function of the decrease of the compound weight occuring during the valve opening of the weighing container (1, 40-42, 46). Thereby, an excellent quality dough is obtained with relatively low production cost and with an adjustment which is at least partially automatic.

Title: Measuring transistor parameters in push=pull stages - using testing frequency , related to mean operational frequency as well as output circuit similar to operational conditions
Inventor: BECKMANN OSKAR DIPL ING
IPC: G01R31/26
Filed: 1980-10-07
Abstract: In the push-pull stages for highly linear amplifiers, wide band couplers and short wave transmit stages the end transistor pair selection should keep the non-linear distortion as low as possible. The testing of individual transistors is carried out at a frequency, corresponding to the mean preset operating frequency, using an output circuit matching the operational conditions as much as possible. With the variable collector current the operational amplification is measured in dependence on the collector current. The maximum amplification value and the respective collector current form the basis for selection of the transistors pairs and for adjustment of the respective work point. The measuring apparatus consists of a calibrated measured level transmitter (1), a calibrated level receiver (2) and an adaptor (3) between these two for the tested transistor (4). The adaptor has an adjustable stabilised current source (5) for collector current, a stabilised voltage source (7) for base-collector voltage and a stepwise variable LC, or RC output circuit (8).

Title: Heat pump for building heating - uses condenser in coolant circuit as room heater without secondary heat exchanger
Inventor: PFEIFER JOHANN B
IPC: F24D15/02
Filed: 1980-10-14
Abstract: The heat pump using Freon (RTM) etc. as the working fluid is applied for heating a building. The condenser (25) supplies heat directly to the building without using a secondary heat exchanger and appropriate circuit, as is usual in this type of installation. To guard against the danger of Freon leakage, a leakage detector (32) is fitted to the circuit and when a leakage occurs it actuates electromagnetic valves (21a,21b). These valves shut off the flow to the condenser and divert it into the reservoir (21). The system receives heat from the surrounding atmosphere through an evaporator (22). An additional source of heat can be obtained by building a second evaporator (10) into a window or door. A solar energy collector can be used with this second evaporator.

Title: Water mixer for domestic washing machine inlet pipes - incorporates thermostatically-controlled mixer valve to maintain required temp.
Inventor: HOLZER WALTER ING GRAD
IPC: G05D23/13
Filed: 1980-10-29
Abstract: Thermostatically-controlled water mixer unit for domestic washing machines, etc. comprises hot and cold water conduits arranged in parallel and joined together by a transverse connecting passage. Within the hot-water conduit is an adjustable thermostatic element, pref. a was thermostat, having a push-rod which controls the mixer valve in the connecting passage. If the temp. of the ingoing hot water is greater than a pre-selected value, the thermostat causes the mixer valve to open to admit cold water into the conduit via the connecting passage. This prevents damage to sensitive fabrics, esp. wool, by the admission of water to the machine at too high a temp.

Patent DE-3047805-A1 (DE)
Title: Thin-walled pyrolytic carbon mouldings - made by CVD on mandrel with pressure equalisation device minimising stress on moulding during cooling and shrinkage of mandrel
Inventor: OESTERHELT GERHARD
IPC: C23C16/01
Filed: 1980-12-18
Abstract: The mouldings are made by the thermal decompsn. of a hydrocarbon cpd. in a reactor, so a deposit is obtd. on a graphite mandrel. The assembly is then cooled so the moulding can be removed from the mandrel. As soon as cooling commences, the mandrel shrinks away from the moulded deposit to leave a cavity which is supplied by the reaction gas to equalise the pressure on both sides of the moulding. The mandrel pref. has an axial hole with a bottom gas inlet; and the top of the hole is closed by a plug. After deposition of the moulding and the commencement of cooling, the mandrel shrinks away from the plug, which adheres to the moulding, so a cavity is provided for pressure equalisation. When the mandrel does not shrink uniformly away from thin-walled mouldings, the latter are subjected to mechanical stress which can fracture the mouldings. The invention eliminates such problems.
