Patent DE-2964888-D1 (DE)
Title: Energy conversion method and system
Inventor: EGOSI DAN
IPC: C02F1/06
Filed: 1979-05-29
Granted: 1983-03-31
Abstract: A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200 DEG -400 DEG  C. The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam. The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection. The compressor is driven by a heat engine whose reject heat is collected and upgraded as well. The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone.
Patent DE-2966209-D1 (DE)
Title: Element for transferring traction forces and use of same as a suspension means for free conductor cables
Inventor: VOSER OTHMAR
IPC: H01B7/18
Filed: 1979-12-03
Granted: 1983-10-27
Abstract: Modern synthetic fibers, e.g. made of aromatic polyamides of high tensile strength have not achieved their potential for use as heavy-duty cables because of their smooth surface which gives rise to considerable difficulties in the transfer of high tensile forces, since they slip out of the clamping sleeves, and other force-transfer means based upon static friction, before reaching their ultimate tensile strength. This problem was solved in the invention by applying to the force-transmitting region thereof an impregnating material which breaks down into powder in the area to which the stress is applied, when the compressive or flexural stress exceeds the ultimate stress limit of the impregnating material. Particularly suitable for this purpose are natural resins, more particularly colophonium.

Title: Process for the drying and calcination of bulk materials
Inventor: KRUGER GERHARD DIPL ING
IPC: F26B3/24
Filed: 1980-12-02
Granted: 1983-10-06
Abstract: A process for drying and/or calcining bulk material in a rotary kiln when hot gases are passed countercurrent to the flow of bulk material thereto, and the bulk material is dried and/or calcined in the rotary kiln is disclosed. According to the invention, the bulk material is dried and/or calcined, as it passes from the feed end of the rotary kiln to the discharge end thereof, by contacting the same with hot gases and thereafter, as the bulk material passes towards the discharge end of the rotary kiln, the bulk material is heated by indirect heat exchange with such hot gases. An apparatus for carrying out such process is also disclosed. The apparatus is a rotary kiln equipped with a centrally disposed tube, disposed axially within the rotary kiln toward the bulk material discharge end of the rotary kiln whereby an annular space is defined between the outer wall of the central tube and inner wall of the rotary kiln. The apparatus is equipped with means for passing hot gases within the central tube, means for passing bulk material on the outer wall of the central tube whereby the bulk material can be heated by indirect heat exchange with hot gases within the tube.
Patent DE-3067828-D1 (DE)
Title: Device for winding up an elongated object
Inventor: BURTSCHER PAUL
IPC: B65H75/48
Filed: 1980-06-27
Granted: 1984-06-20
Abstract: A winding and reeling device for an elongated, flexible member. A reel is connected to the outer end of a spiral spring. The outer end of the spiral spring is rigidly connected to the reel, whereby a gear is connected between the outer and the inner end of the spiral spring such that upon rotation of the outer end of the spiral spring around its center axis the inner end of the spiral spring rotates around the same axis, however at a slower rotational speed. The reel has smooth surfaces and comprises at no place any gear teeth. A rotation of the reel causes the rotation of the gear wheels of the gear, whereby two gear wheels having a different number of teeth are rigidly connected to each other and arranged on a common shaft. A further shaft is provided which carries two further gear wheels, whereby one gear wheel is rigidly connected to the further shaft and the other gear wheel is freely rotatable on said further shaft. The gear is a speed reduction gear, whereby its input end is driven by the reel and its output end drives the inner end of the spiral spring. Accordingly, the space occupied by the spiral spring is smaller than hitherto possible, and a space saving of the entire device is achieved. The device is suitable for reeling weblike members such as measuring tapes or leashes for dogs and also for reeling electrical cables such as for instance used in vacuum cleaners.

Title: Method and apparatus for scarfing
Inventor: MIDDEL JAN
IPC: B23K37/02
Filed: 1982-08-30
Granted: 1985-03-14
Abstract: An inspection track is scarfed by moving a burner across a flat surface of a steel slab, particularly a slab of ductile steel of deep-drawing quality, to enable sub-surface inspection of the slab. To achieve accurate control of the depth of the track, the burner is mounted on a burner carriage having at least one skid surface which contacts the slab surface of the slab at an unscarfed region thereof. A guide track is spaced from the slab surface and the carriage is moved with said skid making sliding contact with the slab surface while guided by said guide track. The skid surface makes substantial contact pressure with the slab surface so that scale on the slab surface is pushed aside and/or crushed by the skid surface, whereby the burner is maintained at a substantially constant distance from the slab surface.

Title: Dental spray handpiece
Inventor: SCHUSS WERNER
IPC: A61C17/02
Filed: 1983-02-24
Granted: 1986-07-03
Abstract: The present invention is directed to a dental spray hand piece which has a valve for controlling the flow of an agent through an agent line that extends through the hand piece to a spray nozzle and an arrangement for preventing dripping of the agent from an end of the nozzle when the valve stops flow of the agent through the line, characterized by the arrangement for preventing dripping including a hose section of elastic material being positioned between the valve and the nozzle, a thrust piece for acting on the hose section in an arrangement for moving the thrust piece from a position engaging the hose section and a second position partially deforming the hose section from an enlarged cross-section to a cross-section of the flow through the valve. Thus, when the valve stops flow the hose section resumes its enlarged cross-section which causes a suction to draw fluid in the line between the valve and the end of the nozzle inward from the end of the nozzle.
