Patent DE-2748219-A1 (DE)
Inventor: KRAKER ALFRED ING
IPC: H04S7/00
Filed: 1977-10-27
Abstract: To insert a single sound event recorded monaurally at any definable location in a quadraphonic total recording, four potentiometers (P1, P1; P2, P2) are provided, the taps (2) of which are connected to a common reference potential and which are connected together in the form of a ring. The input signal of the single sound event, which is to be split into four components (uB) is fed into the four junctions (4) of the potentiometer ring circuit via one constant current source each (VQ, RK, R). From there, the four components are picked up via amplifiers (VT) with a high input impedance. In each case two potentiometers opposite one another in the ring-shaped interconnection can be adjusted in opposite directions. Their axes of rotation (7) are connected to the ends of in each case one strip (6), exhibiting a longitudinal guide slot (5), the strips being located in fictitious concentric hemispherical surfaces and the directions of the potentiometers axes (7) being located intersecting at the fictitious centre point of the sphere in the plane limiting the hemisphere. A joystick-like adjusting rod (8) which passes through the longitudinal slots (5) of the strips (6) is held in a ball hinge (9) which is mounted at the fictitious centre point of the sphere. <IMAGE>

Title: Turbine plant fired by pulverised coal - burns coal in exhaust for operating gas heating and separates particles
Inventor: TAYLOR DAVID W
IPC: F02C1/06
Filed: 1977-11-21
Abstract: The turbine plant has a compressor (13) supplying gas to the turbine (10) as working gas. This arrangement utilises fuels for turbine operation which were previously not considered as directly suitable for this purpose. For example coal can be used for turbine operation. The particular fuel considered as not clean is supplied to the turbine at a particle size less than seventy four thousandths of a millimetre. The fuel preparing system removes pyrites from the coal. This fuel is burnt in the turbine exhaust gases. The gases generated are treated and utilised for indirect heating of the turbine operating gases in the heat exchanger. The coal is milled into fine particles by a jet operated friction mill. The operating gas, which ca be steam, is fed into the coal grinding mill. Combustion products which are detrimental to the turbine are separated.

Title: Induction spool for casting round ingots of ferrous metals and alloys - using inset pieces of high resistivity at current connections to correct electromagnetic field within spool
Inventor: GECELEV ZINOVIJ NAUMOVITSCH
IPC: B22D11/01
Filed: 1978-01-05
Abstract: Round metal ingots are (semi-) continuously cast by means of an induction spool which is circular in form, constructed of a hollow box section material and connected at two points to current feed and discharge cables, the connections being divided by an insulating shield set radially into the spool. On each side of the insulating shield, there are inset pieces of a material with a specific resistivity pref. of the order of 40 to 60 times greater than that of the spool material itself. The function of the inset pieces which are box shaped, pref. three times as long as the width of the spool section with their inner walls lying against the inner wall of the spool, is to concentrate the induction current along the inner face of the spool at the cable connection points thereby ensuring that the induced mangetic field within the spool is uniform. The incorporation of the inset pieces ensures that the cross-section of the cast ingot is uniformly round and undisturbed at the face opposite to the current connections on the spool.
