Patent DE-2755469-A1 (DE)
Title: Centrifugal weight system for engine speed regulation - has separated weights connected by arm pivoted on holder
Inventor: MAKINO NIRO
IPC: F02D1/04
Filed: 1977-12-13
Abstract: The centrifugal weight system is used in a centrifugal force speed regulator for IC engines. The centrifugal weights are pivoted on levers on a shaft connected to drive shaft and the engine speed regulating element is actuated by these weights. The friction force reducing the response speed is eliminated in this system. Each centrifugal weight (4) has two parts (41, 42) and a connecting arm (43) between these two parts. The straight line connecting the centres of gravity of both weight parts has a pivot (5). The connecting arm is arranged so that the weight parts (41, 42) are situated on both sides of the driving shaft (1). The centrifugal force generated causes axial displacement of the output member (6).
Patent DE-2757030-A1 (DE)
Inventor: LEISCHNER MANFRED ING GRAD
IPC: G01R19/04
Filed: 1977-12-21
Abstract: The circuit arrangement prevents the voltage value indicated during the testing of fault current or fault voltage protection switches in systems with inductances from being falsified at the instance of responding due to voltage peaks occurring at the time. For this, a possibility of no longer indicating the half wave within which the switching-off occurs was found. This is done by means of a relay-controlled circuit in which two relays (9, 13) are alternately controlled by the positive and negative half waves of the alternating current to be measured in such a manner that when one contact (4) is closed, the second one (5) is opened and conversely. During this process, a buffer capacitor (3) is charged up by one half wave and during the other half wave this charge is transferred to a storage capacitor (8), the charge of which is then indicated. <IMAGE>

Patent DE-2828955-A1 (DE)
Title: Indirect air cooled electrical machine - has counterflow internal air paths to assist in even temp. distribution
Inventor: HANSPACH HANS
IPC: H02K9/16
Filed: 1978-06-28
Abstract: The air in the internal circuit is circulated by the pumping action of vent slots (20) in the rotor. The cooling air passes through vent ducts (19) in the stator and from the core back into an axial duct through openings (5). The air flows both ways along this duct and enters opposite ends of circumferentially adjacent ducts. These latter ducts have outlets (11) at one end or the other to feed air into each end winding area. Primary cooling air passes through tubes in the axial ducts to extract heat from the air in the internal circuit. The double ended ventilation thus achieved gives more even temp. distribution.

Title: Solar heating system for hot water and room heating - uses photosensitive or thermionic element mounted on rotary rollers
Inventor: HACHT GERHARD VON DIPL ING
IPC: H01L31/052
Filed: 1978-09-11
Abstract: The heating system for a hot water supply and room heating using solar heat collected, as in the main patent, uses photosensitive or thermionic elements instead of absorber plates through which a heat exchange fluid circulates.

Title: Baking oven with hot air circulation - for heat control by average reading of entry and exit thermometers on baking space
IPC: A21B1/40
Filed: 1979-12-24
Abstract: A baking oven, esp. for trolleys with racks, has a circulating heating system with a fan and a thermometer at the entry into the braking space. A second thermometer is arranged at the exit of the air flow from the baking space. The average reading of the two thermometers is used for the regulation of actual temp. This makes the control independent of the degree to which the baking space has been filled by the trolley and the pastry. It ensures that a high heat input is ensured from the very beginning of the baking process. Specifically, a fan circulates the air from a duct, heated by a burner through an entry into the baking space with the trolley, and into an exit channel. A first thermometer at the inlet is supplemented by one at the outlet. Waste air is taken to the chimney through a flue. The ave. temp. reading is taken to control the heat input by the burner.

IPC: C12H3/04
Filed: 1980-03-14
Abstract: In a process for the prodn. of fermented drinks such as beer, wine, champagne, etc., with a reduced alcohol content, the ready-fermented drink made by normal fermentation techniques is passed over a dialysis membrane at a press. difference of less than 0.5 bar. The dialysis fluid on the other side of the membrane, contg. the extract substances, is an alcohol-free fruit drink or an already-fermented drink which has been freed from alcohol. Pref. dialysate fluids are unsweetened fruit drinks or a liquor made by dialysis of a fermented drink. The dialysate liquor may be carbonated. Pref. the dialysate liquor is circulated and the dialysed alcohol is recovered from the dialysate liquor by vacuum distn. Process is economical to operate and does not cause deleterious change in flavour of the drink, as with some prior art processes. The low-alcohol drinks are useful e.g. for drivers, diabetics, etc.
