Patent DE-2019479-A1 (DE)
Title: Furnace head for open hearth furnace using - mainly natural gas fuel
Inventor: I KOKAREW NIKOLAJ
IPC: F27B3/20
Filed: 1970-04-22
Abstract: Head for gas or gas-oil fuel fired open hearth furnace comprises an outer reaction chamber, a mixing chamber, and a vertical channel which is connected with both chambers. The outer reaction chamber is for the partial combustion of part of the heating gases fed into the furnace, soot being generated during this combustion. The mixing chamber is for mixing of the bulk of the fuel with the gas to be reformed. Burners are fitted in front of the entrance of the mixing chamber and at the entrance of the reaction chamber. The first burns fuel with compressed air and the second burns the warm gases introduced into the chamber for reforming and the preheated air coming from the vertical channel. The flame in the furnace chamber is soot-contg., which is desirable. Also, all the brickwork stays warm in the head not in use, when the second head is operative.

Title: Bitumen emulsions - from a homogeneous mixt of bitumen and powdered old rubber
IPC: C08L95/00
Filed: 1971-02-09
Abstract: Bitumen emulsions of use in the protective treatment of buildings and for street surfacing are produced using clays (pref. 40 wt.% kaolin, 50 wt.% montmorillonite and 10 wt.% gangue) as emulsifying additives, and as the bituminous phase, a 1:0.05 to 1:1 mixt. homogenized by heating, of bitumen and powdered old rubber (i.e. the powder obtd. by mechanical pulverization of old motor tyres).

Title: Multi-purpose electronic switch - is suitable for data switching applications
Inventor: SIMMAT SIEGFRIED DIPL ING
IPC: G05B19/08
Filed: 1972-11-20
Abstract: The multi-pole, multi-purpose switch is arranged to rotate about a given axis. At the circumference of this axis there are two sets of wafers that rotate axially, and independently.

Title: Measurement method of a fuel-air mixture - uses an oxygen sensor in the exhaust gas flow
Inventor: BREGLER JUERGEN
IPC: G01N27/407
Filed: 1973-08-01
Abstract: The method is intended for i.c. engines, and the sensor delivers an electric switching signal at a certain composition of the fuel-air mixture or of the exhaust gases, result of the fuel-air mixture combustion. A part of the exhaust gases is separated from the main flow, and a reducing and/or oxidising gas is mixed with it until the sensor delivers its signal. The quantity of the reducing and/or oxidising gas is measured. The quantity of the added gas at the moment of signal delivery is the measure for te fuel-air mixture composition. Before the above gas is added, the fuel-air mixture is tested for being rich or poor, and reducing or oxidising gas is added in accordance with oxygen sensor output signal.

Title: Narrow bandwidth transmission for television signals - involves camera alternately on fast scan viewing and slow scan transmission of image to line
Inventor: DILLENBURGER W DR-ING
IPC: H04N3/00
Filed: 1973-08-01
Abstract: A system for the transmission of television signals over a narrow band width channel involves using a camera and a single storage tube, using a camera which can be switched from normal to slow scan at and appropriate moment to send the signal for storage followed by viewing on a normal television receiver; at the moment of switching to narrow band transmission a shutter cuts off light from the camera whilst scanning continues until the charge is completely removed from the screen. Slow scan is then started the shutter is briefly opened to illuminate the screen with an image which is transmitted and stored at the receiving terminal for immediately following display on the normal television receiver.
Patent DE-2346263-A1 (DE)
Title: Tuning system for several frequency ranges - each frequency band is divided into several of channels with tuners with variable D.C. voltages
Inventor: SONNTAG MANFRED DIPL ING
IPC: H03J5/02
Filed: 1973-09-14
Abstract: The tuners are tuned by application of a variable d.c. voltage. A ring counter has a number of stages corresponding to that of the channels to be selected. Their outputs are connected to a circuit which selects the frequency range and the respective channel by a programmed voltage collected from a corresponding storage potentiometer. A manually, possibly remote control device, controlled clock pulse generator moves forward the ring counter. The clock pulse generator frequency is variable and it can be switched to one of two frequencies. The two frequencies are of the order of magnitude of one and 0.3 sec. The clock pulse frequency may be controlled by a knob from a frequency zero continuously to higher frequencies. The knob is moved against a continuously increasing spring pressure which returns the knob after its release to its initial position.

Title: Fibreboard bonded with synthetic latex dispersions - as natural resin substitute to reduce cost and simplify handling
IPC: C08L97/02
Filed: 1974-04-09
Abstract: A method of making pressed mouldings from wood fibre consists of mixing the fibres with sufficient binding agent to make them transportable, pre-compacting this mixt. to a mat, and then transporting this mat to the final press where it is pressed to shape; the binding agent used comprises synthetic latex dispersions. Prefd. matls. comprise copolymers having free carboxyl gps. of butadiene and/or styrene and/or acrylonitrile and/or methacrylic acid and/or acrylate polymers and/or acrylate copolymers with or without reactive gps.
