Patent DE-3304286-A1 (DE)
Title: Boom for a vehicle used for sailing on water, ice and sand
Inventor: SVENSSON GERD DIPL ING
IPC: B63B35/79
Filed: 1983-02-04
Abstract: The invention relates to the wind energy-related spreadability of the two opposite, outwardly curved arms on the mast-averted side of the boom. As a result, a quasi proportionality of the sail tension relative to the wind force is achieved. This sail tension is achieved via different tensioning mechanisms by converting the length of the spreading path of the arms at the mast-averted end of the boom. This variable sail tension brings about an optimised position of the sail profile relative to the wind. This optimised sail position brings about an improvement in the degree of efficiency of the wind energy. This is achieved, in particular, in gusting wind and strong wind.

Title: Device for mounting a rotary turning tool
IPC: B23B29/034
Filed: 1983-02-24
Abstract: In a device (11) for mounting a rotary turning tool (3), which has a basic body (12) accommodating this rotary turning tool (3) and to be fastened to the work spindle (4) of the machine tool in such a way as to be locked against rotation, a recess (15) which runs at an angle relative to the longitudinal axis (A) of the work spindle (4) is made in the basic body (12), and the turning tool (3) is held parallel to the axis of the basic body (12) in a bush (16) inserted into this recess (15). In order to laterally adjust the turning tool (3), the bush (16) is arranged in the recess (15) in such a way that it can be adjusted in the axial direction of the latter by means of a threaded spindle (22). With little construction cost, this design enables the turning tool (3) to be changed in its position with regard to the rotational axis (A) by an axial displacement of the bush (16) so that the turning tool (3) can be set easily and quickly to workpiece diameters to be machined in different ways. <IMAGE>

Title: Surface-active organofluorine compounds and process for increasing hydrocarbon production from underground formations
Inventor: SEALE VIRGIL LOGAN
IPC: C09K23/00
Filed: 1983-02-28
Abstract: Surface-active substances containing perfluorinated substituents are prepared on the basis of 1H,1H,2H,2H-1-perfluoroalkylethanol, which is either first reacted with an oxirane or a substituted oxirane and then with an epihalohydrin or directly with an epihalohydrin; the halogen compound thus obtained is reacted with less or more than a molecular equivalent of an aliphatic, alicyclic, aromatic or heterocyclic secondary or tertiary amine. The resulting compound or mixture of compounds has the general formula <IMAGE> in which x is a value in the range from 2 to 12, w a value in the range from 0 to 20, y and z are a value in the range from 0 to 20 and the sum of y + z is likewise a value in the range from 1 to 20, R is hydrogen, methyl, ethyl, propyl or a mixture thereof, A is chlorine, bromine, iodine and Q is an ammonium radical derived from the amine. The compounds of this type are brought into contact with hydrocarbon-carrying underground formations and adsorbed on their surfaces; this entirely eliminates or substantially reduces wetting of the surfaces.

Title: Method for manufacturing cleaning scrapers for cleaning brake block guides
Inventor: LEDERLE MANFRED
IPC: B08B1/00
Filed: 1983-03-05
Abstract: The tool which has been developed eliminates the almost metallic corrosion layer, produced by moisture, heat, dust from the road and brake wear, on the brake block guides of the brake callipers at the top and at the bottom. The tool is composed of two parts:     1.) A tool carrier   2.) A scraper element   The scraper element is supplied in 3 different sizes and can hence be used for all makes of motor vehicle. If the scraper element is worn, it can be released from the tool carrier by means of an M4 countersunk head screw and can be removed or exchanged. The tool carrier can be used for all 3 sizes of the scraper elements and for any make of vehicle. The scraper element is composed of a roughly obliquely indented file material or similar material. The tool carrier is composed of a square steel element bent in a swan neck and having a plastic grip. These two components are attached to one another with an M4 countersunk head screw. <IMAGE>

Title: Jigger for dressing coal
Inventor: STRAUSS WERNER
IPC: B03B5/24
Filed: 1983-03-12
Abstract: The jigger is used for dressing coal or other minerals, especially for dressing fine grain sizes, and consists of at least one jig screen on which a throughflow felspar bed is arranged and is periodically pulsed with a separation liquid, and is furthermore equipped with gas-filled chambers, preferably open on one side, to allow the movement of water and to store the pulse energy, the pulsation of the separation liquid being excited mechanically by vibrating exciter elements. The provision of a simple drive for the exciter elements, for example mechanically excited perforated metal sheets, has hitherto been a problem. The problem is solved by the invention in that the vibration of the exciter elements (4) is produced by at least one rotating unbalanced weight (9), the vibrations of which are transmitted by means of a rod (12) to the exciter elements (4). <IMAGE>

IPC: C25B11/04
Filed: 1983-12-08
Abstract: Support bodies made of nickel or nickel-plated steel are coated with a solution containing a ruthenium salt and a solvent for nickel. As a result of evaporating the solvent, the ruthenium salt and the newly formed nickel salt is deposited on the surface of the support body, and as a result of heating in an oxidising atmosphere, a coating is formed which contains essentially ruthenium oxide and nickel oxide.

Patent DE-3347392-A1 (DE)
Title: Device for the automatic control of the balancing pressure on presses
Inventor: GREIS JUERGEN DIPL ING
IPC: B30B15/00
Filed: 1983-12-29
Abstract: The aim is automatic control of the air pressure in piston-cylinder units for compensation of the ram and upper-tool weight of a press. The object consists in the provision of a solution for the detection of the changes in position of two force transmission members within the specified play of the latter relative to one another. This is achieved according to the invention by the fact that a hydromechanical measured-value system, preferably comprising at least one piston (5) and a cylinder (6), is arranged on interacting force transmission members of a play-exhibiting connection point of the force transmission members lying in the force transmission path, which system is in operative connection with a feedline (12) via a pressure line (7), in which are arranged in succession a pressure-recording system, a pressure-relief valve (10) and a non-return valve (11). If, for example, a reduction in the play between the force transmission members occurs, the oil pressure in the oil space of the cylinder (6) and of the pressure line rises and this is recorded by the pressure-recording system. This signal is used for the purpose of commanding filling of the piston-cylinder units. When the balanced condition of the ram (4) is reached, the old desired play and pressure conditions are re-established and the filling of the piston-cylinder units is ended thereby. <IMAGE>

Patent DE-3403097-A1 (DE)
Title: Internal combustion engine
Inventor: KRUEGER-BEUSTER HELMUT
IPC: F01K7/00
Filed: 1984-01-30
Abstract: A heat exchanger winds around an externally heated heat engine so that the high temperatures are focused inside and an outward heat loss does not occur. By means of this focusing a high power output can be introduced with a small heating surface and the entire waste heat recovered. The specific fuel consumption can be reduced to a minimum. By means of a compressor-expander unit an approximately equal pressure is established between the chambers involved, as a result of which the walls are subjected to less stressing and can thereby be kept thin for favourable heat transmission.
