Title: Gas centrifuge esp. for uranium isotope separation - has radial gas inlet duct revolving opposedly to rotor
IPC: B04B11/00
Filed: 1971-10-08
Abstract: The Parent Patent describes a centrifuge separator for uranium isotopes and the like. In this Patent, the gas is introduced into the rotor chamber through radial duct(s) which revolve about the centre of the chamber, in the opposite rotational direction to the rotor, at a speed such that the gas flows from them into the chamber at a speed which is different from, esp. greater than the flow speed of gas produced by centrifugal force within the chamber. Pref. there are independent radial gas supply duct(s) each having a separate drive. Each duct pref. has its terminating outlet in approx. the middle third of the radius of the chamber. Flow conditions within the rotor are improved and interference vibrations are reduced.

Title: Chipboard prodn plant - esp for decorative laminates with time and pressure control
Inventor: KUNZ ALBRECHT
IPC: B27N3/20
Filed: 1971-10-15
Abstract: Chipboard, esp. laminated with decorative finish is made by compressing in a heated multistage press. prepressed cold cakes of wood clipping with curing resin binder. Pressure of the hydraulic press is controlled as a function of time, initially until the cakes have been compressed to a predetermined thickness, e.g. 1.5-2.5 times the thickness of the finished board. Thereafter the pressure is regulated to follow a smooth curve as a function of time using conventional servo techniques. By accurate control of pressure against time, the correct thickness is reached at the instant when the binder cures.
Patent DE-2165418-A1 (DE)
IPC: G02F1/13
Filed: 1971-12-29
Abstract: The space required for electrical connections in small wrist watches incorporating electrical devices such as photo-electric elements or display elements is substantially reduced by the use of stressed metal members making firm contact with each other rather than conventional wiring and solder. This construction simplifies assembly of such watches and makes it easy to break and restore the electrical connections in the event that repair of such timepieces becomes necessary.

Title: Tunnel furnace for roasting carbon containg materials - has combustion chambers for enerating heat in the tunnel
Inventor: KAFTANOW SERGEJ WASILJEWITSCH
IPC: F27B9/36

The conical combustion chambers which join the midsection of the tunnel at right angles are fed at their wider ends tangentially with the mixture of air and fuel gas drawn from the tunnel. These combustion chambers act as cyclones, and the fuel air mixture is blown into these combustion chambers by means of injectors. Butterfly valves regulate gas flow from the tunnel into the injectors. Combustion prods are removed at t he outlet end by another injector which improves the fuel economy and insures intensive roasting of the material.

Title: Thermal cut-out for liquid-cooled transmission tubes - has expanding vapour in tube around anode operating pressure switch
Inventor: BERTELSMANN WILHELM DIPL-ING
IPC: H03F1/54
Filed: 1973-10-15
Abstract: The thermal cut-out for liquid-cooled transmission electron tubes has a gas-or liquid-filled tubular element around the transmission electron tube and in thermal contact with the tube abode outer surface. Changes in the tubular element internal pressure due to changes in the electron tube temperature operate a bellows mechanism that switches off the supply if the electron tube overheats. The tubular element may be filled with toluol. The protective cut-out system operates reliably and gives additional protection to the transmission electron tube. The tubular element may be brazed into a circumferential groove in the anode. A pressure gauge may be connected to the tubular element by a pipe of smaller diameter.

Title: Anti-pollution system for I.C. engine - uses fluidic vortex valve to control exhaust gas bleed
Inventor: HAY NESSIM
IPC: F02M26/60
Filed: 1973-11-14
Abstract: A proportion of the engine exhaust is taken from the exhaust pipe through a branch pipe and a valve and returned to the inlet manifold in order to improve combustion efficiency. The valve is a fluidic vortex type in which a controlling steam of air is injected tangentially across the main flow inlet and the main flow is controlled by the quantity and velocity of the controlling stream. The latter is determined by an air injection pump the output of which is in turn controlled by pressure signals from the engine intake air flow so that the proportion of exhaust gas recirculated to the inlet is determined by engine speed and power output.

Title: Cyclone-filter for dust separation - having cylindrical body made from number of doors which open if pressure rises
Inventor: JAECKERING GUENTER
IPC: B04C5/12
Filed: 1974-08-19
Abstract: Cyclone-filer for gases consists of a lower conical cyclone section and an upper cylindrical section containing a filter medium in the form of sleeves, envelopes or bags, with a horizontal partition between the clean and dirty gas space from which the filter medium is hung. The walls of the cylinder are formed from a number of doors the catches on which are so arranged that the mechanism springs free if the pressure inside the cylinder exceeds a certain value. The outer dia. of the conical cyclone section is greater than that of the cylinder which has a conical skirt which projects into the cyclone, the cone angle of the skirt being greater than that of the cyclone. The partition is formed segmentally and mounted in sealing supports. The cyclone is used for the removal of dust from dust laden gas streams. The cyclone section removes coarse particles while fines are removed by the filter. The cylindrical door construction combines the advantage of explosion relief and good accessibility for filter maintenance. The projecting skirt improves the cyclonic separation.
