Patent DE-2335953-A1 (DE)
Title: Pulse generator for variable amplitude and polarity pulses - has adder stage whose input is connected through switch to voltage source
Inventor: TREUSCH GEORG
IPC: H03K5/01
Filed: 1973-07-14
Abstract: The adder stage has two outputs, the first one connected to a voltage source pole via a switch, and the second input connected via a second switch to the voltage source other pole. The two switches are controlled by simultaneous pulses from a pulse source, and the potential of the voltage source one terminal is variable so that variable amplitude and polarity pulses are collected from the adder output. Thus the pulse generator has a fail-safe operation.

Title: Tyre clamping ring for construction vehicle - to secure inside of tyre on wheel rim for low pressure tyre
Inventor: GOTZMANN WILHELM
IPC: B60B25/00
Filed: 1973-09-13
Abstract: The inside of the wheel rim is fitted with a tensioning band which has side flanges which are shaped to press the tyre side walls into the edges of the wheel rim. The band is made up of a radially divided section so that the effective diameter can be altered, and this is done by a number of set screws spaced around the outside of the wheel rim, in a middle line through the tyre, and when turned alter the pressure of the band. The system locks the tyre on the wheel rim in a simple, effective way and enables the vehicle to drive over rough ground, with low pressure tyres without loosing traction.

Title: Cassette tape recorder spool drive - has swivel plate carrying friction drive wheel actuated by keys of electric control
Inventor: HERLETH KARL
IPC: G11B15/18
Filed: 1973-09-28
Abstract: The drive arrangement for a cassette tape recorder has a swivel plate carrying an electric motor and a friction drive wheel for the two tape spools between which it is positioned. The plate is fastened to the housing through a pivot and is joined to three actuating slides with operating keys, in the front of the instrument, by means of a lever. Contacts at the ends of the slides ensure suitable poling of the electric motor and correct adjustment of its power supply. At the same time movement of a slide moves the swivel plate so that the friction wheel engages against either spool. A slide is preferably provided for the forward and reverse run respectively. Movement of one slide thus provides a countermovement of the other one.

Title: Fire alarm system with quiescent state monitor - accommodates many smoke detectors and checks ccts constantly
Inventor: GREFE HELMUT
IPC: G08B29/02
Filed: 1974-04-10
Abstract: The circuit at each fire transducer, typically a smoke detector switch, consists of several transistors, relays, resistors and diodes, together with a number of circuit breakers. The arrangement is such that in the quiescent state, a current is supplied which holds off an alarm signal different from the fire alarm signal. Any interruption to the circuit, caused by corrosion or even malfunction of the smoke detector, activates this alarm which illuminates a local light and alerts the central control system. A fire alarm also alerts the central control system. This again consists of a complex configuration of transistors, relays, resistors and diodes together with two horns and driving multivibrators.

Title: Damper for mechanical vibration - exerts damping force return stroke after excursion maximum to give one sided damping
Inventor: NICOLAI WALTER
IPC: F16F15/02
Filed: 1974-07-02
Abstract: The damping systems can be of varying designs in a typical system, and the part which vibrates or oscillates to and fro is provided with a wedge shaped protrusion. When the object of which the oscillation is to be damped deflects in one direction, the wedge is forced between two rollers which are spring loaded towards one another. During the outward movement, the rollers will roll along the surface of the wedge shaped extension and little friction or restraining force will be exerted on the moving part. The sides of the rollers are provided with ratchet teeth which engage with a pawl, so that on the return movement of the part, the rollers will remain stationary and exert a sliding friction force on the wedge shaped protrusions.

Title: Low temperature room fire extinguisher system - has compressed water supply line system linking all sprinkler heads
Inventor: EISELE EUGEN DIPL ING
IPC: A62C35/62
Filed: 1974-08-23
Abstract: The automatically operated sprinkler installation is of the dry system type for installation in low temperature rooms or spaces. The sprinkler installation has an additional compressed or pressurised water supply pipe line system (4) of reduced diameter, which is connected to all the sprinkler heads (2) in such a way that after discharge of the sprinkler installation all the sprinkler supply pipes (2) are immediately filled with pressurised water by means of the supply pipe line system. The system control valve (5) is at the free end of the supply to the jet nozzles. These are thus under pressure at all times, which gives a failsafe made of operation.

The flexible tube can be secured to the main tube by means of a peripheral rib engaging in a groove, and the valve can be formed by lips in a flattened-S pattern. The main tube can be rigid or semi-rigid, and preferably of plastic. The diameter and wall thickness of the flexible tube can decrease towards the valve.
Patent DE-2501479-A1 (DE)
Title: Vehicle steering column lock - has lock cylinder key slit closed up by perpendicular disc moving into recess
Inventor: EICHENAUER RUDOLF
IPC: B60R25/021
Filed: 1975-01-16
Abstract: On previous designs, during the inserting of the key a clamping action has to be overcome, which is caused by the pressure of the tip of the key onto wedge surfaces which enter the lock inner space when the key is withdrawn. An additional spring loaded slider would also be provided for the lock bolt, necessitating additional machining and assembly time for the relevant part. The present arrangement provides a disc placed perpendicularly on the key slit. When the key is inserted into the slit the disc is pushed by the thickness of the key into a recess in a rolling movement along the surface of the latch key.

Title: Sausage meat paddle mixer - with inclined paddles attached to semicircular webs standing on edge
Inventor: LUTTE ERNST HEINRICH
IPC: B01F7/00
Filed: 1975-11-05
Abstract: A mixing machine for pasty substances such as sausage meat has two upright paddles which are arranged diametrically opposite to each other and have an inclination of 45 degrees towards the rear. They are joined by semicircular plates, standing on edge, to the hub. The plates have pref. a taper towards the top where they are rounded off. An elastomer sealing lip can be attached to the paddles to improve their seal against the inner walls of the bowl. The arrangement produces a pushing action followed by a suction action on the sausage meat both by the convex plates and by the paddles. The result is a quicker, more intimate, and simpler mixing operation.

Patent DE-2617025-A1 (DE)
Title: Power machine driven by solar energy - produces motion by evaporation and condensation of vapour cycle
IPC: F03G6/00
Filed: 1976-04-17
Abstract: A liquid flows through a solar energy collector and is evaporated. The vapour rises into a vessel in which the press rises as the vapour accumulates. At a sufficient press. a valve in the hose of the vessel opens and admits the vapour into a lower water jacketed vessel. The vapour presses on a plate floating on top of a secondary liq. in the lower vessel. The secondary liq. is formed into a cylinder in which it moves a piston doing useful work. The primary vapour condenses in the water jacketed cylinder and flows back to the inlet of the solar collector. This allows the working piston to drop back and return the secondary liq. into the lower vessel.
