Title: Tyre cast in mould with inflatable diaphragm - using thin elastic film in tread region between diaphragm and mould
Inventor: KEMPTER MICHAEL
IPC: B29D30/06
Filed: 1980-07-10
Abstract: Method of casting pneumatic tyres from castable elastomer consists of inflating a flexible diaphragm (12) inside the mould, so that it bears against the inner mould wall, with the exception of the tread region (20) where the mould wall undergoes sharp changes in form; a very elastic foil (18) bridges across the tread region (and other similar regions). The elastomer is then introduced (14) into the mould, accompanied by corresponding contraction or deflation of the diaphragm (12), and the elastomer penetrates into the space between the diaphragm and the very thin flexible foil (18). The flexible foil is thus forced by the pressure of the elastomer to fit closely to the inner face of the mould in the difficult tread region (20), the air escaping through vents (not shown). The difficult form of the tread region, which is inaccessible to the flexible diaphragm (12), can be fully accommodated by the use of the very thin flexible foil. This foil is used once only.

Title: Construction of wind plants in coastal regions - suspending Magnus rotor by ball joint from four-limbed support structure
Inventor: HANSCHMANN HORST
IPC: F03D3/00
Filed: 1980-08-12
Abstract: The wind generator, consists of a Magnus rotor, supported on a non-rotating axis which, in turn, is held by four steel pillars. The centre axis of the rotor has a ball-shaped upper end, which may be fixed with or without bearings in a cup-shaped recess at the top of the supporting structure. The latter is strong enough to withstand large pressures and storm forces without oscillating or deflecting. The rotor itself is made from steel sheet or polyester with glass fibre reinforcement. The extension of the central axis at ground level is let into a notch which has reinforced side walls, in order to transfer the rotation of the axis due to precession, to the generator. Thus, the base of the central axis can slide into the centre or the periphery of the disc, depending on the prevailing wind pressure. By using a Magnus rotor, and building the wind generator on the coast on high ground, a cheaper installation with a higher efficiency than a conventional wind propeller, can be produced.

Patent DE-3120165-A1 (DE)
Title: Overload and slack-rope safeguard
Inventor: LORENZ WERNER
IPC: B66D1/58
Filed: 1981-05-21
Abstract: The invention relates to the sector of rope tackles of all kinds, including supporting and bracing ropes to be used in a stationary manner, which are to be safeguarded against overload and rope slackness. The aim of providing a simple and reliable safeguard which can be used universally for single-strand and multi-strand rope tackles results in the object of avoiding damping means extraneous to the system and friction-generating force conversions dependent on direction and instead producing, at the two adjustable load limits, transitions between a motionless and a moved state. This object is achieved by means of a two-spring system in a common mounting, having a fixed stop between the two system parts, in which the overload spring rests against the stop between an adjustable end piece and an intermediate piece and the slack-rope spring rests in a pocket between this intermediate piece and a thrust piece. The minimum-load setting is made possible by a second end piece on which the thrust piece rests. The principal sectors of use of the invention are rope tackles with variable pulling directions and minimum and maximum loads. <IMAGE>

Title: Automatic safety gas heating device
Inventor: HUANG MING-FUANG
IPC: F23N1/08
Filed: 1981-05-29
Abstract: Unlike the direct control of a valve of the gas line in a conventional gas heating device, a valve rod connected to a diaphragm operates only a microswitch for an electric control plate. A first gas line and a second gas line, which are connected separately from one another to the nozzle of a pilot burner and the nozzles of a main burner, are in each case controlled by a first solenoid valve or a second solenoid valve respectively. Provided in the vicinity of the nozzle of the pilot burner is a sensor for monitoring the presence of the flame of the pilot burner. When the flame of the pilot burner is ignited by the ignition device, the sensor sends a first electric signal to the electric control plate in order to interrupt the ignition operation of the ignition device and in order to open the second solenoid valve so that gas is supplied to the main burner. If the flame is blown out undesirably during the use of the gas heating device, the sensor sends a second electric signal to the electric control plate in order to continue the spark generation of the ignition device and in order to operate the second solenoid valve so that the gas supply to the main burner is interrupted and uncombusted toxic gas is prevented from flowing out of its nozzle, which gas might otherwise suffocate people.
