Abstract: 1,085,799. Dynamo-electric machines. GOLAY BUCHEL & CIE SOC. ANON. March 7, 1964 [Aug. 24, 1963], No. 50004/63. Heading H2A. A rotary electric motor or generator comprises a stator S having arranged on a circle an even number of field poles 1, 3, 5 sequentially of opposite polarity and of further poles 2, 4 rigid with the field poles and alternating therewith with a constant angular displacement between any two poles, and an unwound rotor R having distributed about its circumference facing the stator a plurality of magnetizable armature sections 6 ... 8 of a number equal to that of the stator pole pairs and each having a circumferential extent substantially equal to the arc between the centre lines of successive further poles so that it can provide flux paths linking simultaneously a further pole with both adjacent field poles the sections occupying substantially the entire circumferential extent of the rotor; the further poles have windings which in the case of a motor are energizing windings but in the case of a generator are induced windings in which magnetic flux reversal is effected by the armature sections alternately directing the field pole fluxes. As shown, the sections are segmental soft Fe sheets embedded in an A1 body 12, and there are two such rotors keyed to a common shaft, a fan 9 impelling an air stream between end plate openings 13, 14; the field poles are energized by either electrical windings or permanent magnets, and there are two stators S, either the rotors or the stators being mutually angularly shifted to eliminate inoperative periods. In an alternative embodiment, Figs. 3 and 4, the rotor is disposed radially outside the stator. As a generator, the machine produces a substantially rectangular voltage, possibly multiphase, the phase number and shift corresponding to the number of stators and their mutual displacement; a two-phase vehicle battery charger is envisaged, and the poles may have short-circuiting rings. As a motor, the further windings are periodically energized preferably through semi-conductors controlled, e.g. inductively, electromagnetically or photoelectrically, by a member rotating with the rotor; speed adjustment is by variation of field winding voltage or selection of energizing winding connections.

Abstract: The invention relates to a method for producing lead having a sulphur content beneath about 2%, from sulphur-containing oxidic lead raw materials contaminated with zinc and/or other readily oxidized elements, by smelting the materials in afurnace in which furnace contents can be agitated. When practicing the method, the lead raw materials are charged to the furnace together with iron-containing fluxes and solid reduction agents. The charged materials are heated under agitation, to form a lead phase and a slag phase. The amount of reduction agent charged is selected so that at least all the lead contained in the furnace is reduced to lead metal and the amount and composition of the fluxes are selected so that a terminal slag is obtained in which the sum of the iron and zinc present is 30-40%, and so that the slag has a content of 15-25% of both Si0<sub>2</sub> and CaO + MgO.Lead raw materials, fluxes and reduction agents are suitably introduced in a plurality of charges, with intermediate moderate heating, prior to commencing the smelting process.

Title: Target tracker with time-variable estimating filter
Inventor: TRULSSON P
IPC: F41G5/08
Filed: 1984-12-21
Abstract: The filter makes use of the information attributable to the time between the actual onset of object position variation and the moment when it was observed, and the data are used in a process of inward pivoting. A memory is incorporated in the equipment, in which the estimating information may be stored. When the filter is set at zero, the memory is connected and feeds the data to it. Simultaneously with the transmission of data by the memory to the filter, it also feeds it with new values covering new estimates commenced after setting at zero. On receipt of data from the memory the filter works at a higher speed in order to catch up with the commenced new estimation. The filter comprises a number of parallel operating units with different starting times, and only one filter unit at a time is connected to the ongoing estimating process.

Title: A coating for metal surfaces which is selectively reflective for microwave radiation
Inventor: BERGQUIST AAKE
IPC: H01Q17/00
Filed: 1989-03-30
Abstract: Metal surfaces reflect microwave radiation. For a long time attempts have been made to coat reflective surfaces with various types of absorbent layer, with varying degrees of success. Particularly when it is a question of reflector antennas, the problem is complicated by the reflector having to reflect radiation at the frequency intended for the antenna. However, this invention solves this problem as it concerns a coating for metal surfaces which is selectively reflective for microwave radiation. It is built up of four layers, designated I to IV, viewed from the metal surface M, with a resistive foil r between the layers II and III. The layers III and IV are quarter-wave transformers, which adapt the surface resistance of the resistive foil r to the wave impedance of free space while the resistive foil r together with the layers I and II acts as a connection device which gives very great reflection around a predetermined reflection frequency but very low reflection at either side. The latter takes place by the resistive foil being short-circuited at the reflection frequency when the layer I acts as a resonator with resonance at this frequency and layer II has an electrical thickness of a quarter of the wavelength at this frequency. <IMAGE>

Title: Method and device for writing and reading data in a memory, method and device for the transfer of data from a synchronous digital hierarchical system to a plesiochronous digital hierarchical system and method and device for adjusting the rate of reading of data from a FIFO register
Inventor: SAHL S M
IPC: H04J3/07
Filed: 1992-05-27
Abstract: This invention concerns the technical field of digital telecommunications. In particular the invention concerns synchronous and plesiochronous digital hierarchical systems and a method and device for transferring information between such systems. The device according to the invention consists of an asynchronous buffer which separates the SDH system from the PDH system. The data signal entering the buffer DATAin can contain a so-called bit adjustment. In bit adjustment the incoming data signal is contained in a frame with one bit more than nominal or one bit less than nominal. The rate of writing into the buffer varies depending upon whether bit adjustment takes place or not. In order to regulate the rate of reading from the buffer so that it follows the rate of writing, the device comprises a FIFO register in which writing and reading of the data information takes place. For writing write addresses WADR are generated and for reading read addresses RADR are generated. The device comprises an average value calculator 38 which generates average value addresses AVADR around which the write addresses WADR oscillate. If the write addresses WADR as a result of the bit adjustment deviate too much from the average value addresses AVADR then the generation of average value addresses AVADR is hastened or delayed in stages so that the write addresses again oscillate within permitted limits around the average value addresses. The generated average value addresses are used in order to adjust the reading rate.  If the read address deviates too much from the average value address then the reading speed out of the buffer is too high, whereupon the reading is stopped temporarily so that the rate of reading becomes the same as the rate of writing. The device comprises a first phase detector 33 for controlling the average value calculator 38 and a second phase detector 40 for regulating the speed of reading from the FIFO register. <IMAGE>
