Patent DE-2436437-A1 (DE)
Title: Fuel tank control liquid balancing method - controls liquid introduced between rigid container and plastic lining
Inventor: HAMMER HEINER I
IPC: B65D90/04
Filed: 1974-07-29
Abstract: Method to fit the level of a control liquid between a rigid container and its lining made from plastic material in the event of a change in the liquid level inside the tank. For this purpose a quantity of control liquid is used which can be accepted in the space below the foil lining given the lowest possible level of the liquid inside the tank without any deformation of the lining. With higher liquid levels inside the tank the pressures of both liquids are hydrostatically balanced with an expanding deformation of the lining. The quantity of the control liquid is regulated and the degree of deformation is used as a measure for the level of control liquid present given a predetermined level of liquid inside the tank.

Title: Plastics insulated communication cable - contains hollow, grease filled, perforated cords extending longitudinally providing waterproofing
Inventor: SCHILLING WERNER DIPL ING
IPC: H01B13/32
Filed: 1974-09-13
Abstract: The cords (2) are provided with heating wires. The cable is waterproofed by heating the cable interior by the heating wires, and injecting the grease, which has been liquefied by heating, into the cable interior under pressure over the cords (2). One cable end is pref. sealed in a vacuum-tight manner, and the cable interior is evacuated at the other end before the introduction of the grease. The perforations (5) in the hollow cords (2) are pref. initially sealed by drawing thin tubes over the cords, these tubes consisting of a shrinkable plastic material, e.g. PVC, crosslinked polyethylene, EVA copolymer, or tatrafluoroethylene/hexafluoropropylene copolymer, that is destroyed by the elevated temp/pressure during the injection of the grease.

Title: Miniature electronic switch compensated for temperature hysteresis - uses damping as well as ferromagnet elements to alter Q value of oscillator
Inventor: SCHWALLER EDWIN
IPC: H03K17/97
Filed: 1974-11-27
Abstract: The miniature electronic switch has a depressable button head whose shaft carries a ferromagnetic element that alters the Q of the resonant circuit of an oscillator. The switching signal is derived in the usual way from the oscillator output. To compensate for temperature hysteresis and to keep the switching characteristics constant, the shaft of the button not only has the ferromagnetic element (39) to increase the Q but also a damping element (38) above it. Both elements pass axially through the resonant circuit's tubular coils (31, 33). The damping element is made of e.g. iron, copper or aluminium, or of a metal alloy.

Title: Proportioning fluid injection into gas stream - with drop-feed and dosage mechanism externally adjustable
Inventor: SPRING OTTO
IPC: B01F5/04
Filed: 1975-03-21
Abstract: A device for the injection of a determined proportion of a fluid in a flow of a gaseous medium has a dosage control as well as a drop feed device for the fluid and a duct for combination with the gaseous medium, such that the dosage control contains a piston, in an airtight cylinder, whose stroke can be limited by a stop, the axial position of which can be altered without breaking the seal. Can be used for introducing oil into an air stream, e.g. for blowing through welding torch nozzles to prevent adhesion of spatter. When gas must not be contaminated with air, dosage rate can be adjusted without opening control to atmosphere.
Patent DE-2516815-A1 (DE)
Title: Ink eraser holds chemical in microcapsules embedded in PVC block - particles rubbed of PVC absorb excess bleach
Inventor: BRANDT HEINZ
IPC: B43L19/00
Filed: 1975-04-15
Abstract: An eraser which neither abrades the paper surface nor leaves excess bleach behind to spoil the written correction is a block of softened polyvinyl chloride contg. 5% by volume of microcapsules of chemical bleach. These rupture under friction with the paper and release the bleach to destroy the writing. It becomes possible to use a much smaller excess of bleach than before, and what little surplus there is, is absorbed by the particles which rub off the PVC block and are brushed away. The paper surface is left able to accept ink normally.

Title: Lever-with-cradle for lifting door from hinges - includes roller on which door can be wheeled away for painting etc.
Inventor: MAURER XAVER
IPC: B66F15/00
Filed: 1975-04-29
Abstract: The device is presented in several versions, in all of which a bent lever (14) has as fulcrum (4) the axis of a roller (8) which rests on the floor. The short end of the lever carries a cradle which slides under the door and raises it from its hinges when the long end of the lever is pressed down. The cradle is made to swivel on the lever, so that the door, once lifted on the cradle, can be turned until it rests also on the lever's long end (which the painter has meanwhile been holding down with his foot). Supported thus at two points, the door can be balanced on the roller and trundled away.

Title: Rabbeting and jointing tool rotary cutter - has compression wedge grip with cutout facing blade lower half
Inventor: RUSAM GEORG
IPC: B27G13/14
Filed: 1975-05-24
Abstract: The function of the compression wedge grip is the fixture of rotary cutters in rabbeting and jointing tools, the cutters being hard metal or high-grade steel units used in woodworking machines. The object is to make it easy for an unskilled operator to set them accurately in position. For this purpose, the rotary cutters are secured in place by wedge compression clamping jaw (2). This pref. involves a cutout on the fitting surface for the cutter (3), mounted opposite to the lower half of the cutter. The pressure wedge clamp is fixed by one or two screws, depending on its breadth, and presses on the cutter across its whole breadth in the cutting direction. A vertical pressure is exerted, effectively preventing displacement of the cutter, which is readily accessible for replacement, even when the appliance is clamped in position on the machine.

Title: System to convert wind energy to storable heat - has heat generating water friction pump driven by the wind-motor and circulation and storage system
Inventor: RIETZ HARALD DU DIPL ING
IPC: F24V50/00
Filed: 1975-06-05
Abstract: A method to convert wind energy into heat and store the energy produced uses a pump driven by the wind motor inserted into a well insulated container with a water medium therein. The energy produced by the rotation of the pump by the wind motor is converted to heat due to the internal friction between the water and the container. The water viscosity and hence friction is mixed by addition of a soluble high molecular weight compound e.g. carboxymethyl-cellulose. The water can also be used to circulate through a solar energy heater and is used to produce waves in an upright hollow container.

Title: Procedure for preventing strata movement in coal mines - uses shock producing tension relaxing measures in region of small reduction of tectonic forces
Inventor: EHRHARDT WILHELM DR ING
IPC: E21C41/00
Filed: 1975-10-03
Abstract: The procedure is for preventing movement of strata esp. in underground mining of coal. Existing differences in reduction of tectonic forces or small reduction of tectonic forces causes by coal extraction are removed by tension-relaxation measures such as shot-firing of shakers, and by tension relaxing boreholes. The intensity of the shock-producing tension-relaxing measures is selected in accordance with the amount of difference in reduction of tectonic forces between adjoining zones (1, 2). When the tension relaxing boreholes are driven through zones with greater reduction of tectonic force and the yield of bored fine coal is considerably increased without corresponding increase in extracted gas, a further advance of the boreholes is stopped.

Title: Coke oven charging hole cover lifter - with slip ring system protected against heat and dust between insulating plate (BE260476)
Inventor: LEEFOGE BARTELT HEERO THEODORU
IPC: C10B25/20
Filed: 1975-10-27
Abstract: A lifting device for the charging hole covers of coke ovens of the horizontal chamber type includes a lifting magnet which can be revolved before re-seating the cover to clear coal dust off its seat. The slip rings for the power supply to the electromagnet are arranged in an insulating part of the rotary section and are coupled to the magnet coils by a plug-in connection. The brushes are fixed with their holders in an insulating cover. This protects the current supply against the ingress of dust and heat and reduces the required maintaince. The electromagnet can be easily removed for inspection. The design is very robust and the danger of internal short-circuits is eliminated.
