Patent DE-2656437-A1 (DE)
Title: HF receiver mixing stage - has resistor in MOSFET source circuit which compensates oscillator frequency changes
Inventor: WEBER HEINRICH ING GRAD
IPC: H03D7/12
Filed: 1976-12-14
Abstract: The mixing stage has a double gate MOSFET, with the input h.f. signal applied to its one gate, and an h.f. signal from an oscillator to its second gate. Its drain is connected to an oscillating circuit tuned to the i.f. A resistor (R5) in the source circuit has such a value, that when the received h.f. signal amplitude fluctuates, oscillator (1) frequency changes due to capacitive feed-back from the mixer stage are substantially compensated. Both gate electrodes of the transistor (T1) are connected together on the output side, with one output lead passing through a resistor (R6) to the tuning coil of the oscillator circuit.

Patent DE-2705322-A1 (DE)
Title: Column for inter-phase contact - with trays provided with collecting zones
Inventor: BRACHEL HELMUT VON DIPL ING DR
IPC: B01J19/24
Filed: 1977-02-09
Abstract: A column producing a large specific phase interface between a light and heavy stream in a heterogeneous (esp. gas-liq.) system comprises >=2 trays separated by a mixing zone in which new heavy and light streams are formed. An enrichment zone for the new heavy stream is located above the lower tray and an enrichment zone for the new light stream is located below the upper tray. At least one of these enrichment zones is connected to the other side of the corresp. tray by a passage for the corresp. enriched stream. The improvement comprises providing the trays with a collecting zone for the ascending (light) or descending (heavy) stream. For the ascending stream, this zone is open at the bottom and is located beneath the corresp. tray. For the descending stream, the zone is open at the top and located above the corresp. tray. The trays need not be hermetically sealed to the column wall, since the collecting zones prevent the passage of the corresp. stream through any gaps between the trays and the column wall.

The metal salts are effective against RNA and DNA viruses; do not induce development of resistant strains; are not teratogenic or mutagenic and do not delay regeneration of affected tissue. They also intensify and extend the activity of (I) allowing smaller doses to be used.
Patent DE-2716394-A1 (DE)
Inventor: MOERTH RUDOLF
IPC: B67D1/08
Filed: 1977-04-13
Abstract: The tap is used to connect two pipes to a removal aperture, e.g. of a beer container. A propellant-gas pipe adjoins the nozzle (11) and the beer flows through the nozzle (6) into a removal pipe when the tap is open. The casing (1) containing the nozzle (11) is fixedly connected to the beer container. The casing contains a valve slide (5) which can be axially displaced by means of a turning handle (20) and is connected to the nozzle (6). To open the tap, the valve slide is displaced downwards. This causes the passage to the nozzle (6) to be opened on the one hand and the connection between the nozzle (11) and the interior of the container to be established on the other hand. A valve arranged in the beer container simultaneously opens the end face (5') of the valve slide (5). This design prevents the undesired outflow of propellant gas and beer when the tap is fitted. <IMAGE>

These, and possibly further exciters form a primary exciter arrangement and have different bundle characteristics. In an alternative arrangement, the primary exciter consists of an exciter group which has different apertures which are activated by switching. This can be excited by a non switched load distributor. In one position a central area is excited, and in another position, the whole group is excited.

Title: Welding mirror for synthetic profile welding machine - prevents damage and discolouration of surfaces by overheating jointing points
Inventor: URBAN JOSEF
IPC: B29C65/20
Filed: 1977-07-30
Abstract: During the welding of the profiled intermediate members into the frame of a door or a window, excessive heating of the point of the double-mitred intermediate profile is prevented. In the inner angle of the angular welding mirror of the synthetic profile welding machine, which heats the point of the intermediate member, there is a zone of reduced heat-conductivity and/or temp. Whilst the heating operation lasts, only a relatively small amt. of heat is imparted to the point of the synthetic profile cf. the other zones which are to form the joint. The profiles are heated uniformly so that good welds are made without damage or discolouration to the surfaces.

Title: Knife for cutting deep frozen food - has battery in handle heating cutting edge by current passage
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: A23G9/28
Filed: 1977-08-02
Abstract: An electrical knife for cutting up deep frozen food with a high water content consists of a metal plate which is subdivided by a slot into a narrow conductor along the cutting edge. The passage of an electrical current from a powerful battery in the handle heats this conductor enough to perform a neat cut. This wastes less substance than use of a saw. Deep frozen food can be divided into clean cut portions without having to wait for unfreezing.

Title: High speed random access memory cell - combines FET and bipolar transistor system as one integrated circuit
Inventor: NONAKA TERUMOTO
IPC: H01L29/80
Filed: 1977-08-05
Abstract: A semiconductor cell has a FET (Q2) with source (S) and drain zones (D) and a channel zone between them, and a gate zone (G) adjacent to the channel zone. It forms a P-N barrier zone defining a boundary of the channel zone to ensure that the depletion layers extend into the channel zone from the gate zone. There is a bipolar transistor (Q1) with emitter (E), base (B), and collector zones (C), the base zone being an extension of the FET drain zone. The collector zone is merged with the gate zone and the drain, source, and emitter zones are taken out as terminals of the cell. The whole forms a random access memory operating at high speed.

Title: Switching system for remote control of loads - has signals passed along power connections from transmitters to switching units
Inventor: PHILIPP DIETER DIPL PHYS DR
IPC: B60R16/03
Filed: 1978-02-16

Title: Flowmeter using Karman vortex path effect - uses twin piezoelectric transducers attached to simple rod vortex generator in flow pipe (BR 20.2.79)
Inventor: SAWAYAMA TAKEHIRO
IPC: G01F1/32
Filed: 1978-06-26
Abstract: The flowmeter consists of a cylindrical tube (1) through which the fluid flows whose flow rate is being measured. A built-in vortex generator (2) is suspended vertically in the tube perpendicular to the axis of flow.

Title: Ductile workpiece conveyor system - has plates transported loose on roller track and returned by belt and lifting mechanism
Inventor: GOLLA FRANZ
IPC: B65G35/08

Title: Packing support automatic removal machine - has three successive sections with rollers and positioning discs at ends
Inventor: VOHR HORST
IPC: B65B69/00
Filed: 1978-12-04
Abstract: The machine automatically removes supports from under packed items, and comprises three sections. The supporting layer with the items on it is brought into place on the first positioning section, and from there transported onto the next ejection section, where the layer is discarded on reaching the end, the items remaining on the rollers. These transfer them to the end section. The positioning section has a number of parallel hollow cylindrical rollers one behind the other, with conical positioning discs on each end, the distance between pairs of discs decreasing from the inlet end, but being always greater than the width of the layer. The ejection section comprises parallel rollers one behind the other, of difference diameters and lengths, all with positioning discs immediately adjacent to the mountings and at the same distance apart.
