Patent DE-2939909-A1 (DE)
Title: Solar reflector for solar-energy retrieval systems - comprises two orthogonal sets of parallel pivoted reflecting strips for tracking sun
Inventor: ROTH JUERGEN
IPC: F24S23/70
Filed: 1979-10-02
Abstract: The solar reflector consists of two sets of reflecting strips (1,2). The strips within either set are plane parallel and each can pivot about its long axis so as to adopt any angle with respect to the vertical. The strips in one set are orthogonal to those in the other set. The sets are placed one above the other. The angles of the strips are controlled so that the solar radiation is reflected onto the energy collecting (or converting) device. The advantage lies in being able to track the sun simply and the reflector is relatively flat and is therefore cheap to make.

Title: Reserve power supply for electronic equipment - has flywheel as energy store either driven by or driving machine housed in bore and acting as motor and generator
Inventor: LUCKE HERBERT DIPL ING
IPC: H05K5/06
Filed: 1979-10-08
Abstract: The reserve power supply has an evacuated casing (2) fixed by elastic members (11) and containing a flywheel (3). A rotating machine (5) is located in a cylindrical bore (4) in the flywheel. When the main power supply is present, the machine acts as a motor driving the flywheel. When the main supply fails, the machine acts as an ac generator driven by the flywheel and supplies the electronic circuitry in the cabinet. A relay (20) operated via a speed monitor (14) and logic (21) disconnects the ac busbar (17) from the main supply (16) when the speed of the flywheel is increasing. Incorporating the machine insid inside the flywheel makes the reserve supply small and allows it to be realised as a slide-in unit.

Title: Controlling gaseous fuel combustion in metal melting furnace - by equalising temperature and pressure of fuel and air prior to combustion
Inventor: BERRY MILTON E
IPC: F23D14/62
Filed: 1979-11-15
Abstract: A combustible gaseous fuel mixture having predetermined constant mass ratio of components for burning in melting furnace is produced by substantially equalising the temperature and pressure of O2 containing gas and hydrocarbon containing gas prior to mixing in a predetermined volume ratio. The gas temperatures are equalised by passing an indirect heat exchange and pressures equalised by sensing pressure of one component and adjusting other accordingly. Air is the preferred O2 source and this may be dried prior to use. The fuel, may need to be vaporised but is preferably natural gas, CH4, C2H5, C3H8, C4H10. The process is particularly employed in melting of Cu. Greater control of gas mixture gives e.g. cast Cu with O content 0.03%.

Title: Internal telephone control system - uses individual telephone set each having four functional buttons and three status indicator lights
Inventor: BIELEFELD JOSEF DIPL ING
IPC: H04M3/56
Filed: 1980-04-15
Abstract: The circuit provides a functional button (Tp) which enables the free accessibility to be terminated and a conversation to be limited to already connected stations. In that state, the additional lamp (Lp) lights up at the 'protected' conversing stations. If thereafter another station tries to reach a protected station, the caller will get no audible engaged signal. If the protected conversation circle decides that other stations may be admitted, the functional button (Tp) must be actuated once more. Thereafter, a connection storage unit (VZS) in the central control unit (ZE) which holds the uncompleted calls, now renews automatically the internal call attempts of the still waiting stations, and these now join the no longer protected station group. Members of a protected conversation are aware of other stations calling through the light of specific colour illuminated on the button belonging to that station. A non-participating station can be called by a member of a protected group to join it.

Title: Automatic lighting control circuit - has SCR to triac switching with time constant light detector control to avoid false operation
IPC: H05B41/42
Filed: 1980-07-10
Abstract: The control is for mains powered lamps to automatically switch them on or off according to ambient light levels. The circuit incorporates circuitry to avoid false switch off due to short term increase in ambient light level, e.g. car headlights or photographic flash striking the light level detector. The design comprises three parts - (1) the lamps and power supply with main switch, (2) the light level detector, and (3) the switch controlled by the light detector output. A time constant circuit (CR) stabilises the output of the light detector circuit (R1,P) which uses for example a photoresistor (P). The operate point of the light detector output transistor (Q1) and the value of the resistor (R4) diode (D2) between light detector and main gate switch (S) determine the switch on/switch off points for given light levels and detector outputs. The main gate switch, an SCR(S), controls, the triac (T) which is in the lamp (L) circuit and switches it on/off directly by carrying its current.
