Patent DE-2605369-A1 (DE)
Title: Control of electrical storage heating - employs semiconductor switching circuit with diode temperature sensor and diode compensating element (OE150576)
Inventor: KALNY FRIEDRICH ING
IPC: G05D23/19
Filed: 1976-02-11
Abstract: A semiconductor circuit is used to generate signals for controlling storage heating. The circuit takes account of ambient temperature and any other reference parameter when recharging of the system is required. The power supply to a storage heating system is switched by a controlled rectifier (31) connected to the control circuit output. A diode (35) in a bridge circuit is mounted adjacent to a supplementary heating resistance (36) affected by the controlling current or by the ambient temperature. A second diode (34) provides compensation and includes a variable resistance (37) permitting the setting of a temperature reference value. The fridge circuit is driven from an oscillator circuit comprising an amplifier (26) and transformer (29). The amplifier provides an output signal with some switching hysteresis for the controlled rectifier (31).

Title: Video disc player audio cutout - senses when signals are repeated using memory system and comparator
Inventor: SCHROEDER ERNST DIPL ING
IPC: G11B27/00
Filed: 1976-02-28
Abstract: The video disc player, for spiral track discs has a picture detector (6-11) detecting when the same track is scanned several times (due to radial jumping) and automatically producing a signal (Us) that cuts out the audio channel (2, 4) to prevent the audio signals being repeated as well as the video signals. The absence of sound is regarded as less disturbing than repeated sound. Two memories (9, 10) alternately retain codes ('1', 'O') representing picture-signal sequences. The alteration depends on the number of rotations made by the disc. A comparator (11) compares the outputs of the memories and produces the sound-blocking signal when they are the same.

Title: Visibility range measuring warning instrument - uses warning lamp triggered by pulse released when path between light transmitter and receiver is blocked by fog, snow etc.
Inventor: FUEHRSEN JOSEF
IPC: G08G1/09
Filed: 1976-03-06
Abstract: Visibility range measuring instrument detection of visibility range limitation by fog, smog, snow-storm, rain etc. at greater distance uses warning lamp. The amount of light allowed to pass between a light transmitter and receiver is limited by fog etc. This triggers a pulse which operates a warning lamp at an adequate distance from the measuring position. The light transmittancy is measured by means of an instrument placed along the road. The warning signal is switched oof if visibility improves sufficiently.

Title: Medicaments for reducing phosphate levels - contg. aluminium hydroxychloride and/or aluminium salts
Inventor: KAEMPER MANFRED DR
IPC: A61K33/06
Filed: 1976-04-24

Title: Combustion engine intake air temp. control - uses hot and cold air mixing valve actuated by vacuum and mixed and cold air thermostats
Inventor: BENDIG LOTHAR DIPL PHYS
IPC: F02M31/06
Filed: 1976-05-29
Abstract: The temp. of the combustion engine intake air is controlled by valve (11) in inlet (8) to air filter (4), which valve is operated by a pneumatic positioner (15) against a spring (17) so as to close a hot air intake (10) when the vacuum exceeds a predetermined value and to open a cold air intake (9). The positioner is actuated via a line (37) connecting with the pressure downstream of the main throttle (3) in the engine suction duct (1). This line contains a thermostatic valve (25) with bimetallicaly (27) operated closure member (28) to open when a given temp. is reached thus producing a connection (29) with the clean air space (5) of the filter. A further thermostat (40) in the cold air intake (9) actuates a movable stop to limit the hot air-admitting opening of the valve (11).

Title: Resistance welded joints for metal furniture or consumer goods - where one workpiece is bent at right angles to make a T:joint
Inventor: SCHAFHAUSEN REINHARD
IPC: B23K11/14
Filed: 1976-06-26
Abstract: A T-joint is made by resistance welding, where one workpiece (2) is bent in a right angle at one or both ends; the other workpiece (1) is aligned so it is at ca. 90 degrees w.r.t. the longitudinal direction of end(s). Alternatively, the two bent ends of the workpiece (2) may pass through two holes in a third workpiece and then be welded to piece (1).

Title: DC voltage converter overload protection - monitors AC pulse decay preventing chopping action until pulse decays to predetermined level
Inventor: SCHMIDTPETER WOLFGANG
IPC: H02M3/335
Filed: 1977-01-07
Abstract: The DC voltage converter employs a high frequency chopper stage and a secondary rectifier for changing the DC voltage. The chopper is protected against overloads by continuously monitoring the rate of decay of one of the critical parameters in the AC link, and inhibiting further choping action until it has decayed to below at set level. The parameters monitored in this way may be output transformer magnetisation, current in one of the transformer windings, voltage induced in a winding, or the change of current in a choke coil in series with the output. The output monitor acts on the chopper control circuit to modify operation.

Title: Guiding welding burner along seam - by optical sensor using binary mask and television camera to feed signals to microprocessor
Inventor: FOITH JOERGE
IPC: B23Q35/127
Filed: 1977-03-17
Abstract: Optical sensor for following a seam during a welding process, where a projector uses a binary mask which is dark on one half to produce a light image(a) of the cross-section of the seam. A television (TV) camera with logic elements converts image(a) into a binary image (b); and the position (c) of the seam or weld gap is calculated from the contour line(d) between light and dark via a microprocessor with rapid external calculated appts. Position (c) is pref. determined from line(d) by electronic correlation with a mask of the seam via shift registers; or by using line (d) as input data for a rapid stack algorithm detecting changes of direction along line(d) and using stored parameters. instead of a TV camera, a diode matrix can be used. Pulsed welding can be used with the sensor; or the projector may use special light detected by filters. Automatic guidance of a welding burner along a seam without using a probe in contact with the seam is provided.
