Title: Window or door joint sealing - with elastic deformable hard-setting two-constituent mass and cementing separator
Inventor: BEUTLER KARL
IPC: E06B7/16
Filed: 1973-12-10
Abstract: The process is for sealing the gap in the closed position between any two building components, one of which is movable relative to the other. The sealing mass, of two constituents, which is plastically deformable, permanently elastic, and hard-setting, is applied to one surface in sufficient quantities for practically filling the joint gap on transition to the closed position. The facing surface of the other component is treated with a separator medium checking adhesion of the sealing mass, and closure is effected, this position being maintained until partial hardening has taken place, any mass that has been pressed out of the joint gap being removed. This can be adapted to joint gaps of any size, regardless of deformations.

Title: Aircraft contra-rotating rotors - each is integral with one half of electric motor with poles working together
Inventor: KLING ALBERTO
IPC: B64C27/12
Filed: 1973-12-12
Abstract: The two coaxial contra-rotating rotors each turn freely about a common imaginary axis on the aircraft frame or a support member. Each rotor (29, 30) forms part of an electric motor, equivalent to the rotor and stator (10, 11) and acting against each other so as to cause rotation in opposite directions. The poles of one or both parts are supplied with alternating current from a generator, typically of the high-frequency type. The generator can have a small number of poles and run at high speed, being of the polyphase type, while the number of poles of the rotors can be greater. Alternatively the generator can be a direct-current one, with an electronic or mechanical converter producing the high-frequency current for the rotors.

Title: Linear actuators with ball or roller bearings - bearing clearance minimised by spring loading from synthetic material insert
Inventor: SIEGEL GUNTER
IPC: F16C1/28
Filed: 1974-01-29
Abstract: Linear actuators utilising ball or roller bearings to reduce friction often generate noise due to bearing clearance. The linear actuator consists of an outer sleeve and an inner shaft separated by ball bearings carried in raceways on the shaft. In order to minimise bearing clearance the shaft is produced in two halves with a synthetic material insert possessing a spring characteristic. The insert forces the shaft sections into contact with the ball bearings and minimises clearances. The principle may be extended to handle roller bearings between flat plates and multi-segment shafts with several roller tracks.

Title: Lubrication system for high speed gear drives - prevents oil loss by pressurised seals on gear wheel rim
Inventor: BRACHTHAEUSER KUNIBERT DIPL IN
IPC: F16H57/04
Filed: 1974-03-12
Abstract: The gear wheel has a smooth rim on either side of the gear teeth. The gear teeth are enclosed in a circular hood provided with a two-part housing on each side, in which the sealing members are retained. Pipes supply gas or liquid at pressure which ensures that the seals are pressed against the rims preventing the escape of lubricating oil from the hood. The solid seals may be replaced by U-section seals, in which the lubricating oil is used as the pressurising medium. Another alternative is to use a rubber tube connected to a pressure source as a lubricant seal. The arrangement prevents losses of lubricant caused by leakages, particularly in the drive of tube mills.
