Patent DE-2362556-A1 (DE)
Title: Piston engine with air compression and water injection - injects less water than theoretic evaporation capacity of the compressed air
IPC: F03G7/10
Filed: 1973-12-17
Abstract: The engine is of the type which compresses air and subsequently injects water just before the working stroke, the work being generated by expansion during evaporation of the water, as in 2329020. The volume of water injected before each working stroke is smaller than the volume which could theoretically be evaporated by the heat contained in the compressed air. The injected volume is preferably 0.8 times the theoretical quantity. An additional amount of water may be injected after a pre-determined number of working strokes. This additional quantity may be approximately equal to the quantity injected before each working stroke, thus injecting double that quantity during this stroke. The increased amount of water may be injected in two portions, whereby the second portion may be injected after the start of the working stroke and before exhaust of the water vapour.

Title: Hot rolling to produce longitudinal profiles - using a pattern which takes up excess rolling forces
Inventor: EMONTS GEORGES ROBERT
IPC: B21H7/00
Filed: 1974-03-02
Abstract: Process for hot rolling a metal workpiece to form a longitudinal profile using a pattern, on a rolling mill whose upper roll chocks are mounted on an oscillating arm which can be moved vertically, and in which the prodt. to be rolled is driven between the work rolls by a horizontally mobile table. A longitudinal cam is fixed on the driven table to materialise the variations of the law of rolling calculated with an extra allowance, and capable during movement of the table of acting, on e.g. a potentiometer which regulates the rolling force. The excess rolling force is taken up by the pattern which is driven between two rollers arranged one above the other, the upper roller being movable upwardly by the pattern to act on the oscillating arm holding the upper work roll, through thrust element.

Title: Christmas tree electric candles with spring clip holders - can be mounted on vertical branches by positioning of sockets
Inventor: SPANGENBERG DIETER
IPC: A47G33/10
Filed: 1974-04-10
Abstract: The candles are provided with socket holders which are connected to one of the clamping jaws of the spring clip which is to be fixed to the tree branch and so that the clip can be attached to upright branches whilst the candle remains vertical the socket is attached to the clip in the plane lying transversely to that of the jaw opening. Where the socket firmly but detachably engages with a corresponding counter member of one of the clamping jaws, the handle end of the spring clip is engaged by a push-on sleeve which in the plane lying transversely to that of the jaw opening has a corresponding counter member to take up the socket connecting member. Thus after removal from the spring clip any chosen candle of a chain can be connected to the counter member of the push-on sleeve so that when off set by 90 deg. it can be pushed onto the spring clip attached to the upright branch.

Title: Plug-in connector with actuator and intermediate element - has tension released spring latch locking intermediate element and socket
Inventor: DIETRICH BERNHARD
IPC: H01R13/71
Filed: 1974-04-18
Abstract: The plug-in connector, applicable also as an emergency cut-off switch, is intended primarily for connecting the battery of a fork-lift truck both for charging and driving purposes. An intermediate element of the plug assembly is movable by an actuator having a relative movement with respect to the plug housing. In the plugged-in condition the intermediate element is locked by a spring latch against the plug housing, the spring latch being delockable by a pulling force. The intermediate element abuts the plug housing via a prestressed spring, while a second prestressed spring presses the plug contact carried by the intermediate element against the contact on the plug socket. Preferably the actuator affects the intermediate element over a freewheel device.

Title: Self loading container lorry - with lifting load frame on parallelogram lever support with single ram
Inventor: KLAUS KASPAR
IPC: B60P1/64
Filed: 1974-10-23
Abstract: The loading surface of the lorry, or trailer, is fitted with a loading frame linked to the vehicle by parallelogram levers so that it can be raised into a position to lift the container off and onto its supporting struts. The lifting frame provides a stable, controlled lift and can be operated by a single, large ram centrally under the frame. The system is stable on uneven ground and prevents the container twisting w.r.t. the lorry frame. The single, large ram is less prone to jamming than are separate rams at each corner of the container, especially with the lateral stability of the lifting frame.
