Title: Membrane valve with spring loaded valve spindle - opens by the action of positive and negative pressure
Inventor: KOSCHUBAT HEINZ
IPC: F16K24/00
Filed: 1974-09-27
Abstract: Membrane valve used for ventilating a fluid tank, has a port which is normally closed by a spring loaded piston plate, whilst a second port is connected to the tank. The valve spindle which carries the piston also has two flange rings for axially moving the membrane which is located between them. When tthe tank pressure is above the required value, the membrane together with the valve spindle and piston are forced away from the outlet port, thus the tank pressure drops. When the tank pressure is below its required value, the active membrane area is reduced by masking ring, the larger piston area causes thus the valve to open, therefore air is able to flow into the tank.

Title: Take-off device for very thin veneer cutting machine - causes delicate veneer to wafted between guides by low pressure air
Inventor: CREMONA ANGELO
IPC: B27L5/00
Filed: 1975-05-23
Abstract: The mechanical devices hitherto used with veneer-cutting machines to take up the veneers as they are cut are suitable, indeed necessary, for the 0.5mm thick veneers produced until recently. The 0.1mm thick veneers now being produced are too fragile and delicate for them. The invention therefore proposes a take-off device in which the veneer is moved solely by low-pressure air currents (fans VA, VB) and passes down a narrow gap between two parallel, curved metal plates (1, 2). Oblique perforations (f) in the plates admit the gentle draught that carries the veneer forward. The guide plates extend the whole width of the machine (4-5 metres) in one or more sections.

Title: Solventless film wire coating process - uses vertical oven through which wires move downwards making several passes (HU281076)
Inventor: LEE JOHN DEREK
IPC: B05D7/20
Filed: 1975-08-12
Abstract: The method is intended for producing solventless and semi-solventless coatings. These coatings have to be applied hot, and the warmth rising from the vertical oven can supply most of the need, if the coating is applied the top of the oven, instead of, in the normal fashion, at the bottom. The wire (1) passes over a roller (2), down past the spray (4) where the hot coating is applied and on down through the oven (5) to a second roller. It returns to the top of th oven for a further coat. When sufficient coats have been applied, it s led away (8) to storage. The oven may well be hotter near the bottom than at the top.
Patent DE-2537167-A1 (DE)
Title: Random sequence generator for digital testing - produces sequences whose length does not depend on store size
Inventor: SCHUNK HELMUT
IPC: H03K3/84
Filed: 1975-08-21
Abstract: The random sequence generator produces repeatable sequences of random signals for e.g. noise testing digital equipment. Each component in the random word has the same probability of occurence. The generator produces sequences that are longer than was hitherto possible. Values are read off in columns from rows of statistical values, and after reading off, one row is shifted. An arbitrary adjustable, long sequence of statistically random numbers is formed by reading out values from a comparatively small store containing discrete, purely statistical random values. The length of the sequence does not depend on the size of the store.

Title: Cleaning domestic ovens - by generating steam and ammonia on adding water to calcium oxide and ammonium salt mixt.
Inventor: BRITE ALAN D
IPC: F24C14/00
Filed: 1975-08-29
Abstract: In process for cleaning fat- and food-soiled surfaces, water is added to a mixt. of CaO having small particle size, an ammonium salt and pref. pine oil in a container. A small quantity of water is contacted with mixt. at the beginning, to initiate an exothermic reaction. Container is introduced into an oven. Balance of water is combined with mixt. quickly, but at a controlled rate to complete reaction and generate steam and NH3 gas from container. The gases are deposited at inner surfaces of the oven. Used esp. for cleaning domestic ovens. Premature generation of steam and NH3 can be suppressed. Use of ammonium salt reduces strongly pronounced, unpleasant smells. Drying and hardening of cleansing agent and fat mixt. are prevented. The pine oil acts as solvent, coats CaO, delays reaction between water and CaO and acts as a deodorant disinfectant.
