Title: Wind driven turbine with vertical axis - has aerodynamic blades pivoting radially between flanges of reel shaped rotor
Inventor: FENKNER MAX DIPL PHYS DR RER N
IPC: F03D3/06
Filed: 1977-04-27
Abstract: The turbine rotor is a vertical reel which has a central cylinder (3) with upper and lower flanges (2). Rotor blades (4) are held on the outside of the cylinder between the flanges. Each blade has an aerodynamic profile and is pivoted on an axis (5) which is not on its mid point. The trailing edge (6) of the blade is guided in slots (7) in the rotor flanges which limit the angular movement of the blade. The aerodynamic action of the wind pivots the blades on one side out and those on the other side in. The blades pivoted out offer a resistance to the wind and produce a turning moment while these returning against the wind are folded in to offer no resistance.

Inventor: BEHA HANSJOERG DIPL ING
IPC: G11C11/44
Filed: 1977-08-04
Abstract: The storage locations are in an interferometer with two Josephson contacts (A, B) interconnected by superconducting inductance (L).

The inductance (L) is suitably divided into inductance (L1) connecting the Josephson contact (A) with the word line superconducting connection point, and inductance (12) connecting the Josephson contact (B) with the superconducting connection point of the word line. Max. currents (IGH) in the word line, which signal existance ranges of a binary 1' or '0' i.e. presence or absence of a flux quantum in the interferometer with disconnected control currents, are practically equal.

Title: Heat exchanger covering wall or roof for gas turbine-heat pump system - has recuperators in outermost layer for heat pump supply in low temp. region
Inventor: BACHL HERBERT PROF DR ING
IPC: F24F5/00
Filed: 1977-12-07
Abstract: The heat pump using a gas turbine combines with a solar heating system using cladding panels of the wall of a building, uses a recuperator formed by the outermost layer of heat collector elements. This collects heat from the atmosphere at low temperatures, and forms part of a heat exchanger having a further inner layer of elements against the wall, for return of heat. The outer layer consists of groups of elements which can be switched into circuit selectively so that under very cold conditions they can be thawed by warmth from the inner elements. These outer elements can be used in the solar heating system.

Title: Strip cable for signal transmission - has parallel core pairs whose conductors lie in two parallel planes and are mutually offset
Inventor: SPATZ JUERGEN DIPL ING
IPC: H01B11/04
Filed: 1978-06-15
Abstract: The core pairs of the strip cable are preferably used for symmetric transmission circuits. The two conductors (2, 3) of all corepairs lie in two mutually parallel planes and are so obliquely mutually offset that the connecting line of both conductors forms a sharp angle with the two parallel planes. On both sides of the conductor planes are preferably arranged conductive plane (5, 6). The strip cable has a negligible cross-talk. An angple of 75 deg. yields a very low coupling values. In this instance it is advantageous the distance between conductors of one pair to be approximately one half of the distance of adjacent conductors of different pairs in the same plane. Several strip cables can be stacked and enclosed in a common sheath. In such instance the conductive planes are desirable only at the lowest, or top most strip cable.

Title: Silencer for IC engine - has intermediate tube between inner and outer tubes to increase low frequency silencing
Inventor: ROSS GUENTHER
IPC: F01N1/06
Filed: 1978-10-07
Abstract: The silencer has an inner tube (3) surrounded by an outer tube (5). Gas enters the outer tube through perforations at the inlet end of the inner tube and leaves it through perforations at the outlet end of the inner tube. This establishes a path parallel to the path through the inner tube. An intermediate tube (14) between the inner and outer tubes is fixed to the inner tube midway along its length. It is open towards the inlet end. This introduces a 180 deg. change of direction in the parallel path which improves silencing of low frequency sounds.

Title: Fan assisted baking oven - uses resistance changes in humidity measuring appts. as control variables to operate vapour exhaust channel flap of oven chamber
Inventor: SCHMIDT ULRICH DIPL ING
IPC: F24C15/32
Filed: 1978-12-23
Abstract: The baking oven has a fan to circulate the hot air in the oven chamber(1) which has an aperture to extract the fumes and vapours. Appts.(7) located in the region of the latter measures the humidity in the extracted vapours. The measuring appts. forms a part of a control unit(8) which regulates the air flow through the oven chamber. Pref. the resistance changes of the humidity measuring appts. are used as a control variable for the air flow. Via the control unit in the vapour exhaust channel(4, 6) a flap(9) is actuated to regulate the conditions in the oven chamber. The exhaust duct outlet is fitted with a nozzle. The speed of the fan motor(3') is alos controlled by the common unit(8) depending on the measured humidity content. The change in motor speed is also affected by the resistance changes in the measuring appts. The oven design prevents sudden and considerable loss of humidity which results in dry, tasteless food.

Title: Power supply arrangement for computerised tomographic appts. - provides X=ray power by slip-ring at HF medium voltage with transformers and closed circuit oil-cooling system balanced on gantry
Inventor: HALL JONATHAN SURTEES
IPC: A61B6/03
Filed: 1979-07-27
Abstract: In a rotating tomographic scanner it is possible to transfer the X-ray tube supply via slip rings. It is difficult to transfer high voltage for the tube by slip rings, yet if the mains supply is transferred the transformers required to give 70KV are excessively heavy for the gantry. It is proposed to transfer the power at 300V, high frequency and then to convert to 70KV on the gantry. The equipment then mounted on the gantry is evenly distributed so that no further counterweight is required. A closed circuit oil cooling system is also provided on the gantry.
