Patent DE-2540408-A1 (DE)
Title: Large hollow structure machining unit - is clamped or magnet attached to oo structure, has accurately adjustable tool holder
Inventor: LANGMATZ HANS
IPC: B23Q9/00
Filed: 1975-09-11
Abstract: Device for carrying out localized limited swarf-removing finishing machining operations in large hollow structures, in which a small, transportable unit can be firmly attached to the structure, and carries a tool holder (18) and to bit (20), the holder being accurately adjustable in several planes. The machining unit can be attached to the structure by clamps or permanent or electro-magnets (6). Where an electro-erosive machining process is required, an additional unit is incorporated for tool feed, being contained in a transportable switch box (21) which is connected to the tool by flexible feed cables (22). The electrolyte fluid for such operations is accommodated by sealed walls surrounding the machining unit.
Patent DE-2542434-A1 (DE)
Title: Ring main switching unit with spur - consists of two on-load isolators which are bridged by off load isolator and is fitted with fuses
Inventor: NEUGEBAUER ENNO
IPC: H02J13/00
Filed: 1975-09-23
Abstract: The application is to cable ring mains distribution systems at the point where there is a spur. A compact and relatively less expensive switching unit is produced by bridging the two series connected on-load isolators (3, 4) joining the cable sections (1, 2) with an off-load isolator (8). By this means an expensive circuit breakers in the spur, for example between fuses (6) and transformer (7) can be omitted. As a further simplification the parallel isolator (8) can be hand operated. With the series isolators open and the parallel isolator closed the spur is isolated whilst the ring remains complete. As a refinement the on-load isolators may be fitted with a charged trip mechanism actuated by the spur fuses (6) to trip if a fuse operates.
Patent DE-2544699-A1 (DE)
Title: Nutritive substratum for germinating plants - has surface partly covered by impervious layer which is harmless to plants
Inventor: RAPPOLD JOSEF XAVER MAX
IPC: A01C1/04
Filed: 1975-10-06
Abstract: The nutritive substratum unit (12) is contained in a saucer-shaped container (10) with a lid (11). The nutritive substratum consists of a fibre mat (13) on the top of which is a layer of seeds (14), which is embedded in a material (15) which is soluble in water, preferably cellulose adhesive or such like, which is harmless to plants. The fibrous mats are packed when dry and placed in a saucer (10), after which the water is poured on, and the lid (11) placed on top. The water in the saucer dissolves or softens the layer (15)1/2. When the seeds, i.e. cress, have reached a height to lift off the lid (11), the seedlings are ready for use.
Patent DE-2600503-A1 (DE)
Title: Indicator for oil mist and smoke in IC engine crankcase - has photoelectric cell generating signal to operate alarm if opacity exceeds threshold value
Inventor: JANSEN KLAUS DIPL ING
IPC: F01M11/10
Filed: 1976-01-08
Abstract: IC engine crankcase oil mist or smoke detection and indication equipment separately samples each crankchamber. Normally, the samples then flow into a common header from which they are drawn into an oil separator. The oil draining from this and any from the header goes to a discharge line. The suction pump fitted to this also draws the sample mixture through a test cell with a light barrier consisting of a light emitting diode of adjustable intensity and a photodiode. After amplification, the signal from this is of a certain strength. At constant light emission intensity this strength will decrease, either slowly due to fouling of the cell windows or rapidly due to oil smoke/mist increasing the opacity of the sample. The slow reduction is compensated for automatically, using electronic devices which increase the light intensity progressively.

Title: Liq. level control device for pipe systems - generates signal to shut corresponding valves or pumps in case of leakage
Inventor: FRIEDL RICHARD DR ING
IPC: D06F33/47
Filed: 1976-01-21
Abstract: In the case of a fault, i.e. a contact between detector and an unwanted liquid, conductance or capacitance between two electrodes is changed, so that acoustic, electric or optical signals are generated. They are received by a respective receiver and shut or disconnect the valves or pumps through corresponding control circuits. The detector electrode lies at the input of an MOS inverter which is connected through a resistor to the supply voltage. The capacitor component of an RC circuit is dependent on the moisture content and this affects the resonance characteristics of a piezo-electric oscillator.

Title: Horizontal ski clamp with vacuum pump - is used to anchor ski for installation of binding
Inventor: LAEMPE JOACHIM ING GRAD
IPC: A63C11/04
Filed: 1976-10-06
Abstract: A clamping device (1) for fixing skis at a working level, uses a vacuum pump (11) to produce the required suction. A horizontal frame (3a) which is mounted on a vertical support (8), has about half the length of a ski. Its top face which equals the width of a ski is provided with a seal all round (5). When a ski is placed onto the frame and a vacuum is applied, the resulting suction holds the ski firmly in position. Thus it is possible to attach a binding to the ski without mechanically clamping it in a vice.

Title: Double acting cylinder hydraulic rammer - can automatically vary stroke length to compensate for pressure variation
Inventor: CORDES HUGO DIPL ING
IPC: E02D7/10
Filed: 1977-02-26
Abstract: The ram head (6) is mounted on the hollow piston rod (4) of a double acting hydraulic cylinder (2). The piston motion is reversed by the valve (12) which is actuated by hydraulic pressure in the control cylinder (9) when the piston (10) reaches the position illustrated, opening the port (19). When the main piston (3) reaches the bottom of its stroke, the aperture (28) connects the cylinder chamber (21) to the control cylinder (9) through the pipe (8), pushing the piston (10) into the position shown. Variation in supply pressure causes movement of the stroke limiting rod (14) adjusting the stroke of the control piston (10) and thus the main piston (3) to restore the supply pressure.

Title: Supercharger for vehicle diesel engine - has rotary piston type exhaust gas motor and rotary piston type compressor
Inventor: KICKBUSCH ERNST DIPL ING
IPC: F02D23/02
Filed: 1977-06-06
Abstract: The supercharger has two cylinders (8, 9) in a common casing (1). Each cylinder contains a lens shaped rotary piston (2) which is mounted eccentrically on a shaft (3) common to both of them. The piston revolves about its own centre as it rotates on the shaft. Air and exhaust gases are admitted through ports (10, 11) in the cylinder end faces which are covered and uncovered by the pistons. The admission of exhaust gas is also governed by a bellows operated valve (5) which responds to the pressure difference between the exhaust and the supercharger delivery air. The width of the driving piston (9) is twice that of the compressor piston (8). The supercharger can be used with a small diesel engine to produce an optimum performance characteristic.
