Title: Hydraulic brakes with pressure reservoir - using mineral oil without oxidation inhibitors to compensate for piston leaks
Inventor: ERDMANN HANS
IPC: B60T13/12
Filed: 1974-10-04
Abstract: The hydraulic brake system operates using a hydraulic pressure reservoir. If the vehicle is left unattended for any long periods then there is a danger of the fluid leaking away especially when the pistons and valves are worn. The invention uses a special mineral oil without oxidation inhibitors and which provides polarised molecules which are absorbed in the narrow capillary spaces in the system and eventually block these. They therefore close up any small gaps between the valves and their seats and effectively seal the reservoir. The oil used eliminates the need for expensive precision fitting valves.

Title: Curved buckle disc for pressure vessel protection - is monitored during production to allow prediction of failure pressure
Inventor: FORTMANN MANFRED ING GRAD
IPC: F16K17/40
Filed: 1975-08-13
Abstract: The curved burst disc is used to protect pressure vessels from excessive fluid pressure under controlled conditions. When the curvature of the disc is produced, the fluid pressure and the deflection are monitored, so that together with the measured thickness of the disc, the final deflection and the required pressure can be calculated. When during this process the applied pressure is momentarily reduced and the resulting reduction of deflection is measured. Youngs modulus of the material can be determined. It is thus possible to predict at what pressure the disc will fail.

Title: Variable vee belt drive - has tapered pulley discs with linear drive for regulating radius of drive pulley
Inventor: HILLMAN DARREL D
IPC: F16H9/18
Filed: 1975-11-18
Abstract: A variable VEE-belt transmission driven by a combustion engine has two sets of tapered pulleys whose adjustable effective radius determines the transmission ratio. One pulley (H) has an axial spring load and its effect radius is regulated by the belt tension. The controlled pulley (F) is regulated by a linear action drive governed by an electronic comparator. The comparator receives two signals from a light reflecting sleeve on the drive shaft. Axially neighbouring zones on the reflector sleeve produce unequal voltages so that the resulting differential voltage can be used to operate the pulley regulator motor until the required constant power transmission is obtained, with the two control voltages balanced.

Title: Cupola with recuperator circuit, for mfg. cast iron - in which accurate control of hot wind temp. is achieved by controlling amt. of cold air
IPC: F27B1/10
Filed: 1976-02-14
Abstract: The air required is heated in a recuperator by the cupola throat gas, which has a variable energy content. The heating of the cold air depends on the actual temp. of the hot wind, which is to be held at a constant temp.

When complete extn. of the throat gas is used, a min. press. is pref. maintained in the charging zone to prevent the entry of unwanted air into the cupola. In mfg. cast iron, the hot wind temp. at the tuyers is pref. 500-700 degrees C, and is controlled to 1% temp. deviation.
