Patent DE-2346238-A1 (DE)
Title: Two-path overvoltage suppressor - has two frusto-conical main electrodes gas-tightly secured to tubular insulator with ring electrode
Inventor: PECHE GERHARD DIPL ING DR
IPC: H01T1/22
Filed: 1973-09-13
Abstract: The suppressor has two frusto-conical main electrodes which are inserted with their mutually facing active electrode surfaces of dished shape in the ends of a tubular insulator in a gas-tight manner. The insulator is divided in its middle by a metallic disc forming a ring electrode which is also gas-tightly inserted. The central opening of the ring electrode has on either side a narrow metal ring which forms with each main electrode a hollow electrode into which an activating emitter layer is inserted. The narrow metal ring may be formed by a soldered or welded stamped component. The active electrode surfaces of the main electrodes may have a wafer configuration. The activating layer is preferably of material with a high electron emission characteristic.
Patent DE-2348937-A1 (DE)
Title: Mixer with integral screen - having rotating and tilting vessel discharging through screen
Inventor: NEITZEL MANFRED
IPC: B01F7/16
Filed: 1973-09-28
Abstract: Mixer, esp. for mixing ingredients for grinding wheels, consists of a rotating vessel into which stationary mixing flights can be inserted and which can be titled to discharge its contents through a screen into a truck. The vessel is coupled directly to a motor and when tilting only a small distance occurs between the edge of the vessel and the screen. The truck can then transport the material. The mixer is esp. useful for mixing and sieving the ingredients of grinding wheels prior to taking them to the press. The small distance between the edge of the vessel and the screen ensures that the material does not separate on screening, which would be deleterious to the grinding wheel quality.

Title: Gas turbine combustion chamber - has heat dependent primary air flow
Inventor: MEYER FRANZ J DIPL ING
IPC: F23R3/26
Filed: 1974-01-24
Abstract: The turbine has an outer combustion chamber housing arranged concentric to the inner housing with a flame tube whose primary air flow channel has over lapping bi-metal strips at the entrance, so that by slow running or low temperature less air is admitted than full load. The mixing jets are arranged as two concentric annular rings behind the air regulating bi-metal strips, guide vanes bent in different directions are fixed between the annular feed pipes to help guide the air in such a way that the fuel leaves the jets with greater speed in order to be emulsified. A starter jet is fitted central to the annular jets. The ante chamber widens into a circular diffuser then tapers back to form two annular spaces concentric to each other flow channel sections whose outlets are partly closed by flame baffle plates. Dilution air enters from the secondary section into openings in the flame tube without regulation.

Title: Identification and measurement of cigarette emissions - using photometric techniques by absorbing gas in reagents in plastic block
Inventor: HEINE MICHAEL
IPC: A24C5/34
Filed: 1974-06-10
Abstract: The components in cigarette smoke are identified and measured by passing the gas through chemical reagents sensitive to tar, nicotine and CO, the resulting change being detected by photometry. The reagents are contained in cavities in a plastic block which also has connecting passages together with the photometric components. The contact is essentially a gas washing device and the cavities are bottle shaped with an inlet for the gas at the gase witha sintered plug. The present and quantity of a component is determined by the colour change in the liquid reagent for the passage of a certain quantity of gas. The vessels are arranged symmetrically around a lamp with a photo-sensitive resistance behind it. Alternatively the light ray passing through the reagent can be deflected by mirrors or prisms onto a centrally located photodetector. Provides a compact and portable method for analysing cigarette smoke. It is small, cheaply constructed, simple to clean, can be erected anywhere and is gag tight. Only one lamp is needed and the reagents are easily changed. Different reagents with different scales can also be used.

Title: Electric power driven dry shaver - has inclined reciprocating cutting head for improving shaving in difficult corners
Inventor: ROESSNER HANS DIPL ING
IPC: B26B19/04
Filed: 1975-01-02
Abstract: The electric power driven dry shaver has reciprocating cutting head in which the cutting edges are arranged at an angle to the direction of reciprocating movement. This arrangement improves cutting effect because scraping action is replaced by direct cutting action and the cutting head flanks also participate efficiently in cutting. The cutting blade perforations are not made uniformly over the whole cutting blade width but adapted from the peak of the curve towards the flank to different shaving conditions. The cutting head formed is adapted to the inclined position of the cutter. This arrangement ensured that shaving is more efficiently carried out for example under nose.

Title: Pulse generator for control circuits - has two timing circuits, one with fixed time constant and other variable
Inventor: BAUM WALTER DIPL PHYS
IPC: H03K3/017
Filed: 1975-03-25
Abstract: A pulse generator for transistorised control circuits, especially when working with extremely long or short keying ratios, in which timing is determined by small time differences between two longer periods, so that the very short times involved do not have to be determined in absolute terms which may be difficult to realise in terms of circuit elements.
