Title: Mine gallery support frame installation equipment - has lifting arm controlled by opposed cylinder pairs and rotated by further pair
Inventor: MAYKEMPER ALFRED
IPC: E21D11/40
Filed: 1977-12-22
Abstract: The mine gallery lining system for securing arches (1) made of channel section, uses a structure (6) forming a working surface which is advanced as the arches are added. This carries a telescopic arm (10) which swings about a hinge point (9) at the leading edge of the surface to lift the sections up to the roof. This action is controlled by two pairs of cylinders (12, 13) which swing eccentrically about the hinge point as their pistons extend and retract. The pistons of the outer pair (12) travel inwards as the arm (10) swings downwards while the pistons of the inner pair travel outwards. This mechanism is mounted on a turntable (7) which is swung about a vertical axis (8) by another pair of control cylinders (16).

Title: Self-locking drive for invalid chair - has DC motor linked to wheel spindle by reduction gearing and automatic band brake
Inventor: STEINMANN HELMUT ING GRAD
IPC: A61G5/04
Filed: 1978-04-18
Abstract: The invalid chair is driven by a DC motor linked to the wheel shaft by a reduction gearing with a small pinion (6) driving the large gear (8) and the axle in two directions. The axle has a band brake (22) which operates an overrun, in either direction. The band brake prevents the chair from rolling away on a slope when the motor is stopped. It effectively allows transfer of torque only in one direction. The brake enables gears to be used as opposed to complex worm gears.

Title: Optical telephone call indicator - has power supply derived from calling signal using high impedance rectifier and capacitor
Inventor: LUEHMANN HANS-GUENTHER DIPL IN
IPC: H04M1/82
Filed: 1978-11-28
Abstract: The optical call indicating system is connected to the telephone line through a d.c. decoupling capacitor (C1) so there is no drain on the telephone system's power supply. Alternating signals-indicating a call-are rectified in a high impedance rectifier (D, R2), and a charge stored in a capacitor (C2). The d.c. supply from the capacitor (C2) is used to power a solid state oscillator (J, C3, R3) which drives the optical indicator (A) at an appropriate frequency. The indicator can be a liq. crystal display or a flashing light. A solid state switch is included to interrupt the supply when the capacitor voltage falls below a safe value. The capacitor (C2) charging time constant is short compared with the discharge time. The optical circuit is in parallel with the telephone and the high impedance input limits damping effects to negligible values.
Patent DE-2852556-A1 (DE)
Title: Three=phase sinusoidal voltage generating system - uses two DC voltages and adds two phase-shifted triangular reference voltages
Inventor: KRUMM MANFRED
IPC: H03K6/00
Filed: 1978-12-01
Abstract: The generator produces three alternating voltages, phase-shifted by 120 deg., of equal and constant amplitudes from two equal and constant direct voltages of opposite polarity, using electronic switches. A first triangular alternating reference voltage (UD1) of constant amplitude, equal to the direct voltages (+UA, -UA), is generated. A second triangular alternating reference voltage (UD2), displaced in phase by 120 deg. w.r.t. the first reference, is generated and is added to the first reference voltage in a specified manner. Non-linear networks are used to produce two sinusoidal voltages (UR, UT) phase-shifted by 120 deg. from the two reference voltages. These two sinusoidal voltages are then added and inverted to produce the third sinusoidal voltage (US).

Title: Monochromatic light frequency determining device - has light deflecting prism and silicon photodetector with properties dependent on light impingement point
Inventor: RAMSHAD SD MEHDI
IPC: G01J9/00
Filed: 1979-01-04
Abstract: The monochromatic light, whose frequency is to be determined, is generated by a laser source. The light (2) is deflected by a prism incorporated in the beam path. Behind the prism is mounted a silicon photodetector (4), whose electric characteristics depend on the position of a light impingement point. The arrangement is such that on impingement of the light beam onto the photodetector the changes in electric characteristics of the same are uses as a rate for frequency determination. The prism deflects the light beam according to the light frequency (2', 2", 2"'). In this way frequency can be expressed as a variable photodetector characteristic which can be tapped by a line (5).

Title: Stress induced crack susceptibility test - for high polymer materials by applying internal pressure on bore by medium
Inventor: PAULAUSKAS FELIX DIPL ING
IPC: G01N33/44
Filed: 1979-09-20
Abstract: High polymer materials are tested for susceptibility to stress-induced cracks by drilling a cylindrical hole in the test piece and by inducing in it a uniform stress field. An elastic hose in the bore is pressurized by a gaseous or liquid medium to exert an internal pressure. This does not require the extremely fine tolerances of the ball impression method and produces a better defined three-dimensional stress state. Balls may also crack very brittle polymer.

Title: Raw wool washing - in which common vessel for washing and rinsing is used to reduce water consumption
IPC: D01B3/04
Filed: 1979-09-24
Abstract: The washing and rinsing cycles, to scour raw wool, take place in the same vessel, with the washing and rinsing fluids being changed. The wool is spun between cycles to remove any water by centrifugal force. The process reduces water consumption, and improves water extraction from the material between cycles. During the washing cycle, the rotation of the vessel is at a low and variable speed, for the washing fluid to circulate from the interior towards the exterior, where it can be drawn out and returned to the centre of the vessel. The vessel is fitted with at least one inlet and outlet for the washing and rinsing fluids.
