Title: Process for removal of heat from pieces of equipment, and device for performing the process
Inventor: BRUENIG MATTHIAS PROF DIPL PHY
IPC: F28F13/02
Filed: 1982-08-09
Abstract: A cooling medium is sprayed in a thin stream predominantly vertically onto the outer or inner wall of the equipment to be cooled. Easily ten to twenty times the stream flow quantity is thereby sucked out of the outer or inner space with good heat transfer onto the blown wall. An electronic equipment box contains, e.g. a pump (3) which sends an air stream against the equipment cover. The heated interior air is thereby completely sucked to the cover when lateral slots allow the air to exit. When a cooling medium stream is blown from outside against a cuboid equipment unit, coolant is withdrawn from the surrounding space. Several cooling surfaces can be blown, thus representing hitherto unachieved cooling action on up to six blown-against surfaces. Surfaces flowed against on both sides in the manner described give new possibilities for heat exchangers of high surface transfer performance. <IMAGE>

Title: Detachable pipe coupling, in particular for composite pipes
Inventor: BOEKER RENATE
IPC: F16L21/02
Filed: 1982-09-13
Abstract: The invention relates to a detachable pipe coupling, in particular for metal-plastic and metal-fibre-cement-composite pipes having spun concrete internal centrifuging. In order to construct such a pipe coupling such that, with a low material cost, it withstands the pressures associated with the steel pipe classes and can be manufactured with low costs and a low fabrication outlay and avoids a narrowing of the cross-section in the pipe, while furthermore allowing optimum corrosion protection to be achieved at the pipe ends, the following design features are proposed according to the invention: a) the coupling consists of an essentially cylindrical ring (1), to be inserted in the pipe ends to be connected, having a cross-section constructed symmetrically with respect to the radial centre plane, b) a slot (2,2') is constructed on the outside of the ring (1) at each end, to hold an O-ring (3,3'), c) a stop ring (4) is constructed in the centre of the ring (1), whose side surfaces merge by means of a ramp (5,5') into the respective outer wall parts (6,6') of the ring (1) said outer wall parts in turn forming a conical jacket enlarging towards the ring ends. <IMAGE>

Patent DE-3244106-A1 (DE)
Title: Trapeze for surfing and sailing
Inventor: BERNER REINHARD
IPC: B63B35/79
Filed: 1982-11-29
Abstract: A trapeze for surfing is proposed which is advantageously distinguished from the known trapezes made of a material similar to clothing material by virtue of the fact that the back part 2 and the side parts 3 are elastically stiffened continuously around the wearer of the trapeze, essentially following the body shape of the wearer. This stiffening prevents excessive contraction of the side parts 3 under the considerable tensile forces which are exerted on the side parts 3 from the trapeze hook 5 via the straps 7 when sailing in a strong wind. In this way, greater comfort compared with the known trapezes is obtained in the face of high winds. Under these circumstances, this comfort also makes possible longer trips without the surfer being overstrained by the trapeze. <IMAGE>

Title: Process for recovering viscous oil from an underground formation containing viscous oil
Inventor: FITCH JOHN LAWRENCE
IPC: E21B43/30
Filed: 1983-01-11
Abstract: Oil is recovered or extracted from a formation, which contains viscous oil and a deposit of tar sand, by providing at least one injection bore and at least one production bore arranged at a distance from the latter, which bores extend from the ground surface in the downward direction to the bottom of the formation and which, in their lower parts, extend generally horizontally through and in connection, via the fluid or medium, with the formation. A predetermined quantity of solvent, preferably 0.05 to 0.30 of the pore volume, is injected into the bottom part of the formation via the injection bore, and oil-containing fluid is extracted or recovered from the formation via the production bore. After the desired quantity of solvent has been injected into the formation, production is stopped and both the injection bore and the production bore are isolated, in order to subject the formation to an impregnation period for a variable length of time, preferably for a period of between 2 and 20 days per 0.30 m (per foot) of vertical thickness of the oil-containing formation. During the impregnation period, substantial mixing of the heavy oil and of the solvent in the formation takes place due to convection under the action of gravity, the viscosity of the heavy oil being reduced, so that its recovery or extraction is facilitated. A propellant medium, for example water, is... Original abstract incomplete.
