Patent DE-2751368-A1 (DE)
Title: Solar energy power system with chemical energy storage - uses ammonia absorption system to store energy during high input periods and release it during low input periods
Inventor: SINGELMANN DIETRICH E DIPL ING
IPC: F01K3/00
Filed: 1977-11-17
Abstract: An energy absorption type power generation system has a chemical thermal energy store which allows variations in input and demand to be smoothed out. The store undergoes reversible chemical reactions and uses the same working vapour (esp. NH3) as the power generator. The heat converter coupled into the thermal circuit is used in conjunction with the store. The auxiliary dilute soln. from the evaporator passes to the store for storage while the strong soln. form the absorber passes through when no heat is being taken into the system. The system allows a steady electrical output day and night by storing energy during daylight for later release.

Title: Inlaid watch face prodn. - uses groove cut ultrasonically into face and insert of same shape fitted into groove
Inventor: BEAUD MARCEL
IPC: B44C3/10
Filed: 1978-02-09
Abstract: A watch face fitted with an inlay, also an inlaid item of jewellery has a groove formed ultrasonically. The groove cannot be made by rotating cutting tools. The ultrasonic process includes the use of a profiled sonotrode and the inlaid section is then fitted into the groove obtained which originates from a metallic profile section identical to that used for making the tool used. The groove may be of any shape, for the decorative effect, and may be star shaped, spiral, zig-zag etc. The sonotrode is therefore of the same shape, and the insert is cut from a tube or strip of exactly the same cross section.

Title: Nuclear fusion power generation - using basic hydrogen atom frequency as high frequency for neutron fusion chamber
Inventor: MISSFELDT WILFRIED PETER
IPC: H05H1/46
Filed: 1978-02-28
Abstract: In a nuclear fusion power station the frequency of 52.629629 MHz of the hydrogen atom is used as economical frequency to produce fusion in a fusion chamber with hydrogen gas. The chamber is equipped with two top electrodes and two bottom electrodes. The direction of the high-frequency can be alternated. The fusion frequency displaces the electron of the hydrogen to the proton nucleus and produces a neutron. The magnetic forces cause the neutrons to combine. The heat produced is used to produce steam for driving a turbo-alternator.
Patent DE-2810866-A1 (DE)
Title: Solar heat collector frame - with one-way lip seals for air between cover and absorber
Inventor: VINZ SIEGFRIED DIPL KFM ING GR
IPC: F24J2/46
Filed: 1978-03-13
Abstract: A one-piece frame for solar heat collectors consists of an extrusion of soft plastic material with a recess for the collector cover pane and a second recess for the collector panel itself. The recesses are sealed by lips which are directed outward on the inside and in the reverse direction on the outside. Air at an excess pressure can thus escape throught he seals to the outside, but on cooling at night-time no air can enter, thus creating a desirable vacuum inside. The inside can also be evacuated initially and the established vacuum will be maintained.
Patent DE-2812648-A1 (DE)
Title: Initiating circuit for thyristor - has two transformers with primaries receiving triggering pulses and discharge diode for capacitor

Title: Voltage-speed converter for IC engine - delivers speed dependent voltage to control fuel injection system
Inventor: GRIMMER FRANZ DR ING
IPC: G01P3/48
Filed: 1978-05-10
Abstract: The voltage-speed converter is used to regulate fuel injection in an IC engine. It converts a speed proportional input voltage into an analogue output. The generator (10) is connected to the engine shaft and delivers a filtered signal (11) to a threshold detector (12). This drives a monostable (13) connected to a storage circuit (14) which is continuously charged by a constant current source (15) and discharged proportional to speed. A peak detector (16) converts the sawtooth output of the capacitor into a speed proportional output signal for further control systems.

Patent DE-2855000-A1 (DE)
Inventor: HELMRICH JOACHIM
IPC: A01K5/02
Filed: 1978-12-20
Abstract: The process and the device are intended for the feeding of animals for which a place (3) is provided for each of them in an animal shed. The places are arranged one next to the other and form a row. A feeding station (23) is moved at a programmable frequency from one place to another, so as to feed each animal according to a plan predetermined by its own needs. The feeding of the animal is generated by individual information provided from each animal. The control may be effected by an information receiver (24) which is connected to a transmitter of information related to the animal. This information transmitter may be comprised of a technical unit applied onto the animal. Further, a natural characteristic outside the latter, allowing its identification with respect to other animals is also taken in consideration as information transmitter and causes the transmission of a pulse into the information transmitted.

Title: Removing glass residue from gob collection rod - where rod is rotated in scraper dish after feeding gob into glass press
Inventor: LIEBAL EBERHARD
IPC: C03B7/22
Filed: 1979-03-21
Abstract: Parent patent described a swivelling and rotating rod for lifting a gob of glass from a tank and feeding the gob into a machine, e.g. a press. The novelty in the present invention is that after shears have removed the gob, the rod is slightly raised so a stripper dish can be moved horizontally into its working position. The rod is then lowered into the stripper dish and rotated so the glass residue on the rod is removed. The stripper dish is rpef. moved between its working and rest positions via a hydraulic or pneumatic cylinder. This addn. uses the stripper dish for effective removal of glass residues from the rod.
Patent DE-2915434-A1 (DE)
Title: Transmission control for forklift truck with electronic speed meter - has automatic gear range change with inhibit on operation during direction change
Inventor: PEPPEL JON HERBERT
IPC: F16H61/684
Filed: 1979-04-17
Abstract: The transmission control is for a fork-lift truck, or a utility vehicle, has the separate gears operated by servo clutches linked to a control with manual and automatic ranges. The control automatically drops the gear ratio if the speed drops under load, and inhibits the gear change during direction change. The control provides additional torque as the vehicle is driven into the load eg. using a shovel. After direction change the inhibit control holds the lower gear for a set time delay to allow the vehicle to pick up speed, before changing up. This provides a smooth torque control.

Title: Centrifugal pipe casting plant - with axially movable funnel loaded by charging hopper
IPC: B29C41/36
Filed: 1979-08-17
Abstract: The Parent Patent No. 2921653 described a centrifugal casting method for pipes of concrete with a synthetic binder. The feed cylinder which can be inserted axially into the centrifugal mould has a funnel which is open along the top and can be charged from a charging hopper with the self-setting cpd. A long feed tube includes a charging funnel which can be inserted axially in the centrifugal mould. A feed spindle at the narrowest point of the funnel can be revolved by a drive. This simplifies the easy charging of the funnel with a uniform distribution of material so that the centrifugal mould is also charged evenly.

Title: Electric arc welding power supply - using DC source for arc striking and parallel sensor controlled AC supply for welding current
Inventor: MAEKIMAA TOIVO TAPANI DIPL ING
IPC: B23K9/067
Filed: 1979-09-27
Abstract: Power supply for electric arc welding plant consists of d.c. source connected in parallel to a.c. source. Before arc is struck, a.c. source is cut off and d.c. source alone supplies ignition voltage. Welding current circuit includes sensors for welding current or for welding voltage. As soon as sensors detect that arc is struck and welding commences, a.c. power supply is connected up to feed arc. Under hazardous conditions (hot and damp rooms, inside vessels with conductive walls), safety rules prescribe low a.c. no-load voltages (12-50V) which may make it difficult to strike reliable arc. D.C. voltages can be higher (80 100 V).
