Patent DE-2746731-A1 (DE)
Title: Solar powered electrical generator - uses solar energy to evaporate gas to drive turbine which drives electrical generator
Inventor: ARMONIES HELMUT
IPC: F03G6/00
Filed: 1977-10-18
Abstract: A liquid is evaporated in a solar energy collector. The resulting gas is taken to a vessel filled with water within which there is a turbine rotor. The gas impinges on the lower blades of the wheel and causes it to rotate. After passing through the rotor the gas leaves the water and the vessel at the top and reaches a condenser above the vessel. The liquid condensed in this returns to the solar collector so that the process is continuous. The water in the vessel reaches the temp. of the gas and the condenser maintains a vacuum above it. The turbine drives an electrical generator.

Title: Cored rope for mooring boat - has electric cable core forming alarm circuit against breakage or theft when rope is moored in bight
Inventor: RENNER LEO
IPC: H01B7/10
Filed: 1977-11-02
Abstract: The cored rope is esp. for mooring boats, to provide a failure alarm. The core is in the form of an electric cable (5) with two or more wires. A special coupling in the rope has a continuous bight in one half. The rope end in the other half forms a loop for laying around a bollard. A permanent magnet in one coupling half closes a reed switch in the other when the coupling is made to complete an electric circuit. An alarm unit in this is triggered if this circuit is either opened or shorted.

Title: Audio programs transmission system using PCM analog signals - involves comparison of sample amplitudes in codewords and replacing
Inventor: PEXA GUENTER
IPC: H04L1/00
Filed: 1978-01-31
Abstract: At least two codewords contg. an instantaneous value companded scanning sample form a subframe, and several subframes form a superframe. The lowest value sample bit in each subframe codeword is replaced by an additional bit. Amplitudes of converted samples in each subframe codeword are compared. The additional bit replaces the lowest value bit in the codeword with smallest absolute amplitude of the converted sample. When two samples are equal, the additional bit is allocated to an agreed sample. Preferably the additional bit appears always at the same place in a subframe. The additional biy may be a parity bit.

Title: Tube made of semiconductor material, esp. silicon - deposited on carrier pretreated with graphite suspension for easy removal of tube
Inventor: RUCHA ULRICH
IPC: C23C16/01
Filed: 1978-06-07
Abstract: The tube is made by chemical vapour deposition of the semiconductor material onto a tubular graphite carrier which is pref. heated by the direct passage of electric current through the carrier; but, prior to deposition, the surface of the carrier is graphitised via a suspension (I) of graphite. Suspension (I) is pref. a 5-10% aq. colloidal graphite soln. which can be sprayed or painted on the carrier; or the carrier can be dipped in suspension (I). Prior to coating the carrier with suspension (I), it is pref. cleaned with CCl2:CCl2 or Ch3OH; and after coating with the suspension (I), the carrier is pref. air dried for 1/2-1 hour. The invention results in the formation of a loose layer of SiC in the bore of the Si tube so the latter can easily be drawn off the graphite carrier, which is then re-used.

Title: Window wood working machine - has two-fold capacity with additional trimming and slitting component homologous to first
Inventor: TEICHMANN BERND
IPC: B27F1/02
Filed: 1978-10-26
Abstract: Assembled on the box-building principle, the machine for working on wooden components for windows has one part for cutting to length and slotting, with an attached part for profiling, a roller bench for workpiece conveyance, and forwarding assembly for these tow processes respectively. The bench has clamps for two similar workpieces, while a second part for profiling is offset by double working width, and screwed to the first as in 2749546. Here there is also a second machine part for cutting to length and slotting, sited homologously relative to the first part for this function. Its interval is adjustable to the length of the workpieces concerned. This obviates any need for two-fold clamping ont he roller bench.
Patent DE-2850177-A1 (DE)
Title: LF amplifier for car radio - has output level detector for automatic power supply voltage change according to amplifier load
Inventor: WELLHAUSEN HEINZ DIPL ING
IPC: H03F3/183
Filed: 1978-11-18
Abstract: The circuit changes the voltage level of the audio stage, typically by a factor of two, when the power demand exceeds a set threshold, and switches back to the lower value when the demand falls below the given limit. The advantage of the voltage change is that at high power demands the max. power output limit of the amplifier is raised when required whilst the steady state losses remain at a low value. The voltage changing circuit (15) may contain a voltage doubler (18) and a complementary switching transistor pair (19) under the control of a level detector (20). The latter is responsive to the output of the audio amplifier (10, 11). The amplifier power supply (16, 17, U3) is then switched in response to load demands.

Title: Active aerodynamic control surface using no medium - has inertial gyroscope drive and braking unit in rotor lamination packet of electromotor
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G05D1/00
Filed: 1979-04-07
Abstract: An active medium-free control surface can be used with electrical braking motors. A high step-up transmission is achieved for the gyrostabiliser by having a large bevel gear diameter at the bushes and a very small diameter for the gyroscopic driving wheel or an idling, supporting free wheel. The bevel gear roller bushes are inserted in a cage or at the gyroscope. An inertial gyroscope drive and braking unit is inserted into the rotor lamination packet of an electro-motor with a housing. This unit is rigidly fixed to the rotor e.g. by bearing plate flanges, so that the housing serves as driving and motor shaft. The latter is flatly supported in one position against the motor bearing plate and rotatable about the neutral axis.

Title: Prodn. of granules contg. poly:phosphate and aluminosilicate - by contacting powdered mixt. with superheated steam
Inventor: USSAT WOLFGANG DIPL CHEM DR
IPC: B29C48/50
Filed: 1979-05-30
Abstract: Prodn. of granular prods. contg. higher polyphosphate (I) and ion-exchanging alkali metal aluminosilicate (II) is carried out as in the Parent Patent (DT 2714604) with the improvement that the powdered premix of (I) and (II) is passed downwards through a pipe, in which it is contacted with superheated steam at 100-140 degrees C and dried in a hot air stream. Products are useful as builders for detergent compsns. and as water softeners. The process gives non-caking free-running, abrasion-resistant granules without the use of wet granulation (cf. DT 2714604).
