Title: Temperature effect compensation during density measurements - compensation is continuous and direct and based on hydrostatic difference pressure
Inventor: KRUEGER KLAUS
IPC: G01N9/26
Filed: 1974-07-24
Abstract: The compensation is based either on the hydrostatic difference pressure or on the buoyancy measurement.

Title: Deep well drill - has linear motor coils for drill collar in hollow drill bit with cable power supply
Inventor: HENSBERG FRIEDRICH
IPC: E21B11/02
Filed: 1974-08-28
Abstract: A drilling appliance for boring deep wells of small dia. consists of a hollow drill bit with a pointed forward end of slightly larger diameter than the stem. A drill collar with a thick forward end can exert impacts on the bit to drive it forward. The drill collar is reciprocated by the coils of a linear motor which surround the thinner upper end of the drill collar and are enclosed in a magnetically soft housing. A cable supplies the necessary power. This is a very inexpensive appliance compared with the conventional drill rigs. Very great depths can be reached at small diameters because no mechanical link is required to the surface. Suitable coil design results in high number of blows and high acceleration.

Title: Negative mould prodn. for investment casting - for fabrication of lost wax or plastics patterns
Inventor: WINKEL MARTIN
IPC: B22C7/02
Filed: 1974-09-25
Abstract: The prodn. of negative moulds for use in the lost wax casting process comprises applying a metal coating by means of a spray gun to the pattern of the workpiece to be cast, over an inter. layer, using an impingement temp. of 150-1400 degrees C. After solidification of this metal coating, the pattern is heated in order to remove the inter. layer by liquefaction or evaporation, afer which the negative mould is separated from the pattern. The inter. layer is produced from a material of which the m.pt. is considerably lower than that of the spray metal coat of the negative mould and that of the pattern material. Pref. the inter. layer is produced by applying a spray coatng of Sn, Bi, white metal or similar low melting metal. For the metal coating, forming the negative mould, which is also applied by spraying, steel, alloy steel or similar high melting metals or alloys are used in powder form or as wire. Pref. a dry powdered sinter metal is used. The inter. layer is applied by spraying in which simultaneously thin wires and/or foils extending outward from the pattern are coated at the pattern end, the m.pt. of the layer material being considerably lower than the m.pt. of the negative mould spray coating, and higher than the impingement temp. when spray coating the negative mould material. The inter. layer has a thickness which corresponds closely to, or is only slightly greater, than the shrinkage.

Title: Blast-furnace throat gas treatment - in which gas is purified, then reheated and fed through an axial turbine
IPC: F02C1/05
Filed: 1975-07-15
Abstract: A turbine is operated with blast-furnace throat gas which is purified by a wet method and then heated before entering the turbine. The temp. of the throat gas is raied by a value approx. matching the temp. drop produced in the turbine, the heating of the gas being obtd. by heat exchange with a current of steam coming from the blast-furnace cooling system or with steam heated by the throat gas before the latter is subjected to wet purificn. An axial turbine can be used which has higher efficiency than a radial turbine and the thermal stresses, e.g. when the turbine is stopped, are reduced in the system; heat-utilisation being high.

Title: Welding electrodes for coating reinforcement materials - with synthetic film, has electrode profiles modified to prevent overheating transitional zones
Inventor: VERSTEEGE ARNOLDUS JOSEF
IPC: B29C65/04
Filed: 1975-08-28
Abstract: The lower of a pair of welding electrodes for coating or enclosing a reinforcement material such as carton, leather, etc., between two bands of synthetic thermoplastic for document cases, book covers, foodstuff packets, etc., is cut away relatively to the upper electrode in the zone which during working, is adjacent to the edge of the reinforcement material and extends inwards. When the lower electrode is a plate, in the zone opposite to the side of the upper electrode which is close to the edge of the reinforcement, a cutout is machined in the plate over part of its thickness. When the electrodes are rods, in a direction outwards from their centre line, the lower electrode is narrower than the upper. When the upper electrode is a cutter with a side face, the face of the lower electrode adjacent to the face of the upper electrode away from its cutting edge, is offset inwards from that face. Method prevents the formation of bubbles, wrinkles and holes with other deformation in the zones adjacent to the weld, due to overheating, by restricting lateral radiation from the electrodes.

Title: IC engine fuel metering system for different fuel types - has fuel volume regulated in response to electric resistance of fuel
Inventor: ABTHOFF JOERG DR ING
IPC: F02D1/00
Filed: 1975-10-04
Abstract: The electrical resistance value of the fuel type to be used is determined and the result used to adjust the fuel feed correspondingly. A conductivity sensor (7) is fitted to the carburettor float chamber and the fuel metering valve is adjusted correspondingly to the amplified tension difference. For application with indirect fuel injection the conductivity sensor is fitted inside the fuel injector main feed pipe. A higher alcohol content in the fuel produces a higher degree of conductivity and a corresponding longer injection time.

Abstract: A heat exchanger for transferring heat from one particulate solid material to another comprises a cylindrical vessel contg. conical and/or truncated conical baffles which lead to the formation of self-mixing piles of particulate material. The rate of heat transfer between the solids is high due to the intimacy with which the solids are mixed. Different desorbed gases can be collected separately from the heat exchanger. Used e.g. in desorption of sulphur oxides from active carbon in the treatment of flue gases from power stations.
