Patent DE-2450759-A1 (DE)
Title: Generator for carrier FM with video signal - designed for recording on video disc with carrier frequency and phase periodically adjusted
Inventor: WALLOW HANS-JURGEN ING GRAD
IPC: H04N5/92
Filed: 1974-10-25
Abstract: Adjustment is carried out during line blanking period by a control variable derived by phase comparison between the modulated carrier and a reference carrier. It is additively applied to the f.m. modulator together with the video signal. A second carrier f.m. with the video signal is generated in a second f.m. modulator with its frequency adjusted to a constant value by the reference carrier during the front porch. The control variable is obtained by phase comparison between the second carrier and the reference carrier during the front porch at the end of a line. It is added to the video signal at the first modulator input during the whole line duration.

Title: Fire proof door - has double walled metal cover plates with low melting point and a fire resistant filling
Inventor: KAEUFERLE JOSEF
IPC: E06B5/16
Filed: 1974-11-14
Abstract: Part of all of the metal cover-plates (1, 2) of the fire-proof door are made of a material with a low melting point, such as aluminium. The cover-plates may be joined at certain parts by narrow bridge-pieces. The thermal bridge between the two plates is interrupted by a gap (4). The cover-plates are anchored to the filling which can be, for example, asbestos cord (3). The latter forms a heat insulation between the two door cover plates, so that overheating on one side is not immediately transferred to the other.

Title: Electronic contact switch - has its state is changed by brief touching of a key
Inventor: BRUNGSBERG HEINRICH-JOSEF
IPC: H03K17/96
Filed: 1974-12-06
Abstract: The circuit closed by the contact delivers a pulse to an electronic power circuit e.g. a relay or a read contact), so that contacts of a power circuit are closed or opened. No more than two contact keys (13) are provided in an operating circuit (IV). When one of them is touched,a pulse is delivered to a bistable element (7) in the control circuit (II). This circuit (7) controls a transistor (6) which switches on or off the power circuit (I). A power pack (III) supplies the necessary current. In another embodiment of the invention, a field-effect transistor is used controlled by a PUT-VIZ. a thyristor tetrode, in place of a bistable element.

Patent DE-2516056-A1 (DE)
Title: Separation and refining of inorganic fuel residues - using circular furnace with downwards flow round sharp bend to disentrain droplets
Inventor: WOTSCHKE JOHANNES DR ING
IPC: C03B5/26
Filed: 1975-04-12
Abstract: Inorganic liquids draining from hot masses are treated and refined in a furnace under pressure in which the hot gases leave via central downwards outlet. The hot gas channel turns through a sharp angle from vertical to horizontal and because of this entrained liquid droplets separate out on the base of the bend in a sump by centrifugal action. It is further heated in this sump, stirred and homogenised by allowing a certain residence time, being impinged on by the hot gas stream. The purified exhaust gases flow on to a heat exchange operation and the liquid inorganic components are drained off via a seal or weir. This process can ve widely used in metallurgical processes, glass making, operation of smelting furnaces, firing of oil shales, incineration of household and industrial refuse. In the past it has often been necessary to use additional energy and furthe effort to produce the inorganic material as granules and not as dust. Thus afterburning is used to suppress dust and additional separation processes to follow. The system described avoids this and allows the liquid material to be drained out.
Patent DE-2522950-A1 (DE)

Title: Twin chamber toilet cistern - has separate discharge systems for each chamber with common down or outlet pipe
Inventor: BAUMEISTER ALEX ING GRAD
IPC: E03D1/14
Filed: 1975-06-12
Abstract: The toilet cistern, of roughly cubic construction, has a bell or float discharge action device operated by an external handle and having a float operated water inlet valve. Its internal space is divided into twin chambers of differing volume by a vertical separator wall. A water level equalising pipe or hole at the base of the separator wall permits equalisation of water levels in the chambers. Twin external operational buttons allow each chamber to be independently activated through individual bell or float valve systems, allowing discharge through the common down pipe into the toilet base.

Title: Foot washing and massaging machine - has massaging flow round feet from pulsator wheel in fluid container
IPC: A47K3/022
Filed: 1975-08-18
Abstract: This foot washing and massaging machine consists of a container for the cleaning fluid, into which is fitted a fixing plate (4). On this plate at one end (5) is a pulsator wheel (6). This wheel is driven by an electric motor (8) at the top end (7) of the plate (4). A protection grid (15) is fitted round the pulsator wheel (16). A base grid (19) is fitted to keep the feet at a distance above the bottom of the container. The fluid is circulated at high speed round the feet in the container to wash and/or disinfect them, while at the same time the pulsating effect massages them. A water heater can be fitted in front of the pulsator wheel or in the base grid to warm the water. The pulsator wheel can also be replaced by an ultrasonic oscillator. This allows the feet to be massaged on all sides without the necessity to move them. The machine is cheap to produce and requires little space for storage.

Title: Yielding arch support for mine roadways - has stay width tapered from flange end to rounded head end and adjoining overlapped segments
Inventor: LOESKEN GUENTER
IPC: E21D11/20
Filed: 1976-03-02
Abstract: Yielding arch supports for mine roadways consists of tee segments placed with their flanges alternately inside and outside and held together where overlapped by turn-buckles. The free end of the stay forms a head rounded at the side and thus wider than the stay where it joins the flange but narrower than the segment foot. The stay width changes steadily from the flange (5) downward so that adjoining segments when overlapped make continuing contact from flange down to head end (3). The curvature (r4) of the rounded sides (4) of the head (3) equals the curvature (r5) at the flange end of the stay (5). Pref. the sectional width of the stay should increase rectilinear from flange to head end. It is possible to incorporate a circular thickened part in the stay, halfway between flange and head ends, and approximately the same section as the head.

Patent DE-2638311-A1 (DE)
Inventor: IKENO HITOSHI
IPC: H03B5/36
Filed: 1976-08-25
Abstract: In order to manufacture a time-base signal generator, a quartz crystal having dimensions included within predetermined tolerances is formed, this quartz crystal is connected to an oscillating circuit and to a frequency divider, these circuits being constructed such that the division ratio is adjustable. According to the invention, the crystal is of the GT-cut type and the polishing is carried out in such a way that the ratio between the width (w) and the length (l) has precisely the value which corresponds to a zero frequency/temperature coefficient. The width and the length may have values which depart from the nominal values provided that they remain within the tolerances ( DELTA w) and ( DELTA l). Under these conditions, the generator of the time-base signal entirely forgoes any temperature-compensation element. <IMAGE>

Title: Railway crossing obstacle detection system - uses one divergent beam microwave transmitter and several receivers on each side of track
Inventor: GRUEN HELMUT DIPL PHYS
IPC: B61L29/24
Filed: 1976-12-15
Abstract: A device for detecting obstacles between the barriers of a level crossing uses at least one transmitter producing a microwave beam on a barrier on one side of the track. There is a corresponding receiver on a barrier on the other side. When the beam is interrupted or attenuated by more than a specified amount an alarm signal is generated. The method achieves full coverage of the danger zone with fewer transmitters and reduced decoupling problems resulting from reflections and interference. One transmitter is used on either side of the track. It is placed at the end of a row of receivers associated with the opposite transmitter and emitting a fan-shaped beam.
