Patent DE-3031050-A1 (DE)
Title: Hydrogen of commercially acceptable purity - obtd. by electrolysis of water using soluble metal anodes evolving no oxygen
IPC: C25B1/12
Filed: 1980-08-16
Abstract: Hydrogen is obtd. by the electrolysis of conductive water in a pressurised reactor vessel contg. a cathode, usually the reactor itself, and a metallic anode. Hydrogen ions are discharged at the cathode and liberate the gas which is removed through a valve. At the anode the current density maintains oxidn. reactions, while its metal ions go into soln. but can be pptd. as hydroxide with the discharged hydroxyl ions, and hardly any O2 is evolved. The hydroxides are generally derived from a Fe anode and when withdrawn from the reactor can be reduced to metal and reformed as anodes. Pressure in the reactor, made of corrosion-resistant alloy, is below 30 bar. Gas suitable for many industrial purposes or as fuel in IC engines is cheaply prepd., since distilled water is not needed (sea water is a suitable electrolyte). Reactor pressure is low, and electrical energy can be derived from solar cells, wind-power etc.

Patent DE-3035645-A1 (DE)
Title: Correction of plesiochronous digital signals in demodulator - uses logic circuit to damp out sudden phase changes
Inventor: BARTEL WILLY DIPL ING
IPC: H04J3/07
Filed: 1980-09-20
Abstract: The very high speed data transmission systems, for e.g 34MBits per second uses multiplexing. The object is to correct for small deviations between the transmitting and receiving ends of the system. The transmitter sends the interleaved data in blocks bounded by pseudoframes. These are received and stored in a register and then read out by a pseudoframe counter controlled by synchronising data. The logic circuit in the demultiplexer is intended to provide a continuous phase change of the pseudoframe counter. It is composed of a series of gates, bistable stages of a monostable circuit, and two inverters. It sets the first stage counter w.r.t the incoming reset signal. Using the matching information from the timing signal of the counter, it also inhibits sudden phase changes without altering the timing of the onward transmission of the digital signals.

Title: Oil burner fine spray jet formation - is produced by swirling flow injected into chamber with radial air entry tubes
Inventor: PETERSON FOLKE PROF
IPC: B05B7/04
Filed: 1980-10-24
Abstract: The jet forming device for producing very fine spray particles (10) is suitable for an oil burner. The liquid is discharged from a tube (10) into a chamber (12) formed by the converging ends (18) of an outer tube projecting forwards beyond it. Assisted by air flow between the tubes and guide vanes (16) around the end of the inner tube, a whirling flow is produced. This enters a reaction chamber (20) inside a larger tube (28), assisted by a gas flow entering through a number of radial jet tubes (30) increasing the swirling action. A distributor body (21) can be supported in line with the discharge opening (22) of the first chamber. The amount by which the tubes project into the larger chamber can be adjusted. The tubes can also be fitted at an angle to act tangentially on the helical swirling flow. The design reduces pollution by the burner.

Title: Digital driver stage for transistor switch - receives lower reference voltage than that fed to switch stage
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H03K19/0175
Filed: 1980-12-09
Abstract: The driver stage (A) for a switch stage (B) using transistors with a low response threshold itself exhibits a higher response threshold and is supplied with a reference voltage (n1) less than that for the switch stage (B) in relation to the supply potential (P). Pref. the difference between the two reference voltage (N1,M) is equal to half the difference between the response threshold of the driver stage (A) and that of the switch stage (B). Pref. the driver stage (A) uses an OR gate (2) and the switch stage (B) uses a MOSFET (3), the former being preceded by an AND gate (1). Both gates (1,2) receive a positive supply potential (P) and the reference voltage (M) for the AND gate (1) and the MOSFET (3) coupled to a negative potential (N) via a series diode (4) and resistor (5), the reference voltage (N1) for the OR gate (2) taken from the junction between them.

Title: Articulation for luminaires
Inventor: HILLEBRAND EGON
IPC: F21V21/26
Filed: 1981-01-17
Abstract: The luminaire articulation has two articulation halves which can be rotated with respect to one another and are provided with mounting or connecting pieces for luminaire arms, the luminaire foot or the luminaire housing. The two articulation halves can be rotated steplessly about an axis holding them together, and are held in the respective rotary position by a runner ring situated between their bearing surfaces and by a spring element acting in the longitudinal direction of the axis of rotation. A further spring element acting in the direction of rotation supports the torque of the two articulation halves and provides these two articulation halves with a configuration which is easy to rotate. The two articulation halves are constructed to be identical as far as possible, are shaped like a pot and are held together by means of a head bolt held non-rotatably in one articulation half and a screw engaging therein; the bolt and the screw form the axis of rotation. Arranged between the bottom of the pot and the screw head of one articulation half is a disc spring whose loading can be set by the screw, and a face seal ring is provided between the head of the bolt and the bottom of the pot of the other articulation half. Mounted about the axis of rotation as a torque supporting spring is a helical spring which is held with its end spring limbs in grooves in the articulation halves. <IMAGE>

IPC: F26B3/28
Filed: 1981-01-20
Abstract: Process for the more rapid drying of plastic lids which are transported on a conveyor band made of fabric or rubber and which are held in an inclined position. Only one lid edge is in contact with the conveyor band. The conveyor band is limited laterally by respective angle irons which have the form of a horizontal "T" with a basic and a transverse web, the transverse web having a limiting effect on one side of the conveyor band and the transverse web being directed outwards on the other side of the conveyor band, and the inclination of the lid being determined by the horizontal basic web which is parallel to and at a specific distance above the conveyor band and which provides support for the lid. The lids are drawn in the inclined position through a superstructure under intrinsic rotation and are supplied with heat, and at another location they pass through a channel having cooling tubes.

Title: Device for determining control variables of an internal combustion engine operated with supercharging
Inventor: BONITZ JOERG DIPL ING
IPC: F02P5/153
Filed: 1981-02-21
Abstract: A knocking control device for supercharged internal combustion engines is proposed, which immediately after knocking occurs opens a control valve in the exhaust bypass in order to reduce the rate of delivery by way of the charging pressure and, where necessary, simultaneously retards the ignition timing. Charging pressure and ignition timing are then returned to their normal settings with different time constants. In so doing it is intended that the ignition angle should regain its normal setting more quickly. By means of the device proposed a very rapid reaction to the occurrence of knocking is achieved and hence optimum operation of the internal combustion engine at its knocking limit. <IMAGE>

Title: Method for the high-temperature soldering of workpieces made of highly heat-resistant materials
Inventor: STEFFENS HANS-DIETER PROF DR I
IPC: B23K1/19
Filed: 1981-10-13
Abstract: The invention relates to a method for the high-temperature soldering of workpieces made of highly heat-resistant materials, such as iron-, nickel- or cobalt-based alloys. Use is made in the conventional way of a nickel- or cobalt-base solder which has a liquidus temperature above 900 DEG C which is heated in vacuo or under a protective gas to a temperature above the liquidus temperature and is introduced between the joint surfaces of the workpieces to be joined. The object of the invention was to find a method of either entirely preventing or minimising, with minimum technological complexity and low energy and cost expenditure, the formation of marked strength-reducing brittle phases which has hitherto occurred in methods of this type. The essence of the invention is that, after heating the region around the solder seam to soldering temperature, a process in which the solder and the parent material are heated very rapidly, the joint surfaces of the workpiece are pressed against one another at high speed while applying little pressure and the pressure is maintained during the soldering temperature holding time.
