Title: Energy generation system - uses tube in sea water to take advantage of ellipsoid shape of earth
Inventor: WAGNER KARL DIPL ING
IPC: F03B17/00
Filed: 1991-02-06
Abstract: The system generates electrical energy, by utilising the revolution ellipsoidical shape of the earth, and the flattening of the earth from equator to the poles. A water tube (1) of suitable geoid shape (2), is installed in suitable sea or coastal areas in the northern hemispere, to extend from a point P1 to a point Pn, which is located northwards on the same degree of longitude. The gravity point distance of a mass m in the tube decreases continously, and thereby a usable water fall height is created between water tube outlet in Pn, and the geoid course at thhat point. Together with the volume of seawater Q in m3/sec flowing through the tube, this supplies water power and electrical energy in a hydroelectric power station at point Pn.
Patent DE-4104868-A1 (DE)
Inventor: DOROSCHENKO VIKTOR
IPC: C08J9/06
Filed: 1991-02-17
Abstract: The invention concerns an electrical winding with a conductor layer (14) which is sealed in an insulating layer (30) of polyethylene. The polyethylene has a degree of crosslinking of at least 60 % and contains an anti-oxidant. The starting material used is a not yet crosslinked polyethylene to which a foaming agent is added so that, when heated to be crosslinked, during which it also melts, the polyethylene penetrates between the individual turns (20) in the conductor layer (14). The protective insulating layer (24) round the individual turns of the winding consists of a material which is stable at the crosslinking temperature.

Patent DE-4134353-A1 (DE)
Inventor: RITTER JOACHIM DIPL ING
IPC: B60N2/22
Filed: 1991-10-17
Abstract: A free-running roller coupling transmits in both directions of rotation a torque between two structural members. This coupling has an outer ring (1) in which clamping tracks (4, 5) are formed by recesses. An inner element (9) has a cylindrical clamping track. Pairs of clamping rollers (6, 7) prestressed by a pressure spring (8) against the ramp-like end of each clamping track (4, 5) are arranged between the clamping track (10) of the inner element (9) and the clamping tracks (4, 5) of the outer ring (1). In addition, the coupling has an unblocking arrangement (11) for loosening the clamping rollers (6, 7) from the clamping tracks (4, 5, 10). In order to simplify the design of such a coupling and to allow the outer ring (1) to easily swivel in relation to the fixed inner element (9), the unblocking arrangement (11) has comb-like carriers (12) that extend through slots (16, 17) in an edge (14) of the outer ring (1). These comb-like carriers (12) unblock at the same time the free-running rollers and allow the outer ring (1) to be driven by a switching sleeve (13).

Patent DE-4140339-A1 (DE)
Title: Continuous thin metal strip casting - gives preformed edges to give consistent metal structure at sides
Inventor: BIRAT JEAN-PIERRE
IPC: B22D11/06
Filed: 1991-12-06
Abstract: In the continuous casting of thin metal strip (4), esp. of steel, the small surfaces of the metal strip (4) are preformed from the filling of the liquid metal into the pouring zone (3). This gives continuous surfaces for the small sides of the strip, according to their final form, according to the edges of the metal strip (4). Pref. each of the side closing plates (10) has a decreasing cross section into the pouring zone (3) as a projecting pouring funnel. It has a straight section (14) at every level with a length generally equal to the thickness of the metal strip, to form a central groove (14a) of the level of the pouring funnel. The cross-section in the lower level of the pouring zone (3) is reduced to the straight section (14). The gap between the straight sections (14) of the two side closing plates (10) at the level of the lower plane in the pouring zone (3) is generally equal to the width of the metal strip. The circumcircle of the pouring zone (3) is generally constant at every level of the side closure plate (10). The pouring funnel (13) of one of each closure plate (10) is symmetrical to a symmetrical plane of the metal strip (4) which is at right angles to the straight section (14) through its centre. ADVANTAGE - The method ensures that the behaviour of the metal at the side zones of the cast strip is consistent with the final strip shape and structure.

Title: High productivity recovery of meat from animal (esp. cattle and pig) carcasses - by pressing section of carcass between shaped dies to separate bones, and pressing meat etc. through perforated drum to remove sinews etc.
Inventor: KLAASSEN LAMBERTUS G M
IPC: A23L13/20
Filed: 1992-01-30
Abstract: In the process each body part is placed between suitably shaped pressing tools, and is correctly orientated within these tools; the pressing tools are closed under pressure so that the body part is sepd. into a skeletal part and a part consisting of meat contg. sinews, ligaments, skin, etc.; and the second part undergoes a sepn. process in which the meat is sepd. from the sinews, etc.. USE/ADVANTAGE - For high-productivity recovery of meat from animal carcasses. A high proportion of the available meat is recovered without increasing its calcium content (due to breaking down of bones) or destroying its fibrous structure. The labour required for trimming and prepg. the animal body parts can therefore be reduced without loss of productivity

Title: Generating multipath reception interference simulation test signal - sampling and digitising analog FM HF signal by A=D converter to test radio receiver
Inventor: NIEMCZYK NORBERT
IPC: H04B17/00
Filed: 1992-10-23
Abstract: The digital data sequence from the a-d converter (12) is temporarily stored in a FIFO memory (14). A programmable counter (18) coupled to a control circuit (16) has a preset reading. The counter (18) is started by the control circuit (16) on detection of the start of the data sequence and the count is incremented with the read in rate of the FIFO memory (14). The control circuit (16) starts read out of the data from the memory (14) when the counter reading reaches null. The delayed digital data sequence read out in synchronism with the read-in rate is converted back to an analog time-delayed HF signal by a d-a converter (20). The level of the time delayed signal is varied in small steps by a programmable normaliser (22) before it is added to the undelayed HF signal in a summer (26). ADVANTAGE - Simple, inexpensive system which generates accurately reproducible test signals and time delay is adjustable.
