Patent DE-2554484-A1 (DE)
Title: Monitoring system for hydraulic bearing - has spring loaded ram to sense impulse of oil flow at limiting volume
Inventor: SCHUMACHER HANS
IPC: F15B15/28
Filed: 1975-12-04
Abstract: The monitoring system is for hydraulic bearings on armatures, particularly remotely controlled bilge pumps and fuel transfer pumps on ships. It overcomes the difficulties of electric switches and cables operating in adverse conditions e.g. under water. Measurement of the oil flow is dependent on a limiting or critical value being reached in the volume measuring system. A spring-loaded ram or plug contacts the gearwheel when the limiting valve is reached. A non-contact electrical or optical monitor produces impulses which are recorded on a register which includes a frequency filter and is based on a condenser circuit which compares the actual voltage generated against the pre-set figure.
Patent DE-2607925-A1 (DE)
Title: Friction clutch with leaf spring mounted pressure plate - has restricted axial movement to protect leaf springs
IPC: F16D13/71
Filed: 1976-02-27
Abstract: A vehicle friction clutch has a pressure plate (3) which along its circumference is attached to the clutch housing cover (2) by means of leaf springs (5). The pressure plate (3) is actuated by a disc spring which is subjected to an axial clutch operating force. In order to prevent overstressing of the leaf springs during clutch installation, axial safety stops (12) are provided. The restriction of the axial pressure plate movement is produced by the extended leaf springs (12) coming into contact with the stops (13) on the cover plate (2). The full wear on the friction plates can be used up before the axial stops (12, 13) are in operation.

Title: Perylene-(3,4,9,10)-tetracarboxylic acid bis-butyl-imide - used to give brown colour to rigid PVC, providing high IR remission
Inventor: GRASER FRITZ DIPL CHEM DR
IPC: C09B5/62
Filed: 1976-03-26
Abstract: Perylene-3,4,9,10-tetracarboxylic acid N,N'-bis(n-butylimide) (I) of the formula is used as brown colour for rigid PVC. The brown colour has excellent fastness to light and weather and good compatibility with rigid PVC. The Ir remission is high, so that exposure to sunlight does not cause as strong heating as in the case of other dark pigments. The (I)-coloured PVC profiles are of esp. interest for window frames and shutters as imitation for wood.

Title: Freight container handling system - has crane to lift all in stack necessary for access to particular container
Inventor: EISELE HERBERT
IPC: B65G1/04
Filed: 1976-07-02
Abstract: The system is for handling stackable freight containers, using buffer stacks in a storage yard in which the containers are deposited in rows and stacks by a travelling lifting device such as a crane. The crane (8) is capable of lifting all of the individual containers stacked one above the other for access to a particular one or to any desired position in a stack not yet full. The crane lifts the container or the one occupying the desired space, and those above it, high enough for the container concerned to be removed from or delivered to the space concerned. The containers lifted are then lowered again into the space left, and the container concerned delivered if necessary to the loading point.
Patent DE-2630516-A1 (DE)
Title: Precision investment casting with blocks - providing reservoirs for molten metal and so eliminating air inclusions
Inventor: COOPER ABRAHAM J
IPC: A61C13/00
Filed: 1976-07-07
Abstract: Precision investment casting of small parts by the lost wax method, ensuring freedom of air inclusions, is achieved by using a transversely bored, rectangular heat-destructible, reservoir blocks within which are received on an elongated heat destructible sprue pin. The patterns are secured to the end of each sprue pin and each block is secured to its respective sprue pin at a point adjacent but spaced from the pattern. The free ends of the sprue pins are secured to a base and placed within a flask so forming a hollow body to receive investment material which hardens around the patterns and their supporting structures. The investment is then heated, allowing the blocks, sprue pins and patterns to melt, and flow out having a metal pouring cavity with adequate reservoirs close to the casting cavities. Method provides the simultaneous casting of several small parts, ensuring freedom of shrinkage or air voids by the use of adequate reservoirs for the molten metal. Used for casting of small dental restorations and other small parts e.g. rings, buttons, settings, etc.
