Title: Detector which finds metal pieces picked up by vehicle tyres - uses electromagnet to produce oscillations that trigger warning signals on dashboard
Inventor: HAASE WOLFGANG
IPC: G01V3/10
Filed: 1978-10-23
Abstract: The metal detector warns a driver of damage to his tyres by detecting the presence of metal pieces picked up from the road. The driver may then stop and remove the metal and repair the tyre before any serious damage is done or an accident occurs. An electromagnet is located in the mudguard of the vehicle and scans the surface of the tyre whilst the vehicle is in motion. The electromagnet passes oscillations to a switching circuit that releases warning signals on the driver's dashboard. Several electromagnets may be connected one behind the other. The detector is capable of scanning the entire surface of the tyre for metal pieces.

Title: Plastic petrol can blow moulding - mfd. by co-extrusion of thick compatible inner and thin antistatic outer plastic layer
IPC: B65D25/38
Filed: 1979-04-06
Abstract: A can for the storage and transport of explosive material such as petrol is produced from plastic material by blow moulding. A co-extrusion technique is used to combine at least two plastic layers. The inside layer is compatible with petrol and the outside layer is made of a plastic with a max. surface resistance of 109 ohm at 500V. The percentage weight of the thinner outside layer is not more than 20% of the total can weight. Suitable materials are low pressure or high molecular polyethylene for the inside, and the same with a carbon black admixture for the outside layer. The plastic material with carbon black admixture must be imported and costs 2 1/2 times as much. The new process therefore produces such cans at much lower cost.

Title: Integrated thermal processing of particulate solid fuels - gives coke, water gas, tar, and heating gas from coal
Inventor: CHUCHANOV ZINOVY FEDOROVIC
IPC: C10J3/54
Filed: 1979-08-17
Abstract: A process is claimed for the two-stage pyrolysis of fine-particled solid fuels, with sepn. of vapour, liq. and fine coke prods. At least a part of the fine coke is subsequently heated to 800-1500 deg.C by combustion gases and/or its own partial combustion. It is partially gasified with steam, the residue being used, together with combustion gases, to provide heat for the first pyrolysis stage. Combustion gas is also used for drying the fuel. The process yields transportable fuels and chemical prods., and is useful in power generation. Because of process integration, the overall energy efficiency is high (84-88%). The yield of chemicals is high because of the low temp. of the heat source in the first pyrolysis stage.

Title: Piezoelectric detection of IC engine knock vibrations - using single element centrally clamped to provide two independent vibrators
Inventor: BOENING BERNWARD DR ING
IPC: G01L23/22
Filed: 1979-11-06
Abstract: The sensor for detection of the vibrations occurring as a result of engine knock contains a piezoelectric element and clamp giving a wider bandwidth than conventional arrangements yet suffers no reduction in the magnitude of its resonant peak. This ensures maintainance of the signal-to-noise ratio at a conventional level. The piezoelectric element (1) is clamped so that at least two sections of it are able to vibrate. The clamp (2) may act in the middle of the element so as to produce two equal length vibrating parts (3,4). Selective detection of two frequencies is possible using only a single mechanical clamp. This results in a reduced number of transducers and parts. The transducer signals can be connected in parallel using common electrodes.
Patent DE-2944751-A1 (DE)
Title: Gas cooled machine with heat exchanger tubes in stator casing - has radial and axial deflector plates guiding gas flow to give evenly distributed cooling
Inventor: HANSPACH HANS
IPC: H02K9/18
Filed: 1979-11-02
Abstract: The cooling tubes (23) of the heat exchanger (30) are mounted in a circumferential space outside the stator core (21). The machine stator (21) and rotor (20) are provided with cooling ducts, and are enclosed by covers with inlets and outlets. The outlet gas is confined within one section of the cooler by circumferential platen (5) and radial plates which divide the cooler into sectors. A part-cylindrical plate (4) divides the cooling tube space into two sections, one radially outward from the other, and gives a counter gas flow between sections. The direction of gas flow alternates between each circumferential sector, of which there may be for example eight round the machine. This gives a cooled gas inlet to each end of the machine, and only small temperature differences between ends. A more uniform temperature distribution in the machine results.
