Title: Electrical motor or generator with magnetisation in axial direction - has ring shaped armature formed from spiral strips and square cross section iron core
IPC: H02K23/54
Filed: 1975-07-22
Abstract: Electrical motor or generator with magnetisation in the axial direction, producing a very favourable power to weight ratio. The magnetisation field is produced by permanent or electromagnets (12) mounted on a magnetically conducting end plate (12). The armature or stator is made with radial slots (23) which contain the armature windings. The iron core (18) of the armature consists of a ring shaped body formed out of one or more strips (27) of dynamo sheet material wound in a spiral. The cross section in the axial plane of the ring forming the iron core is near enough square (A). The dimensions are calculated to obtain the maximum produce of the cross-sectional area of the magnetic field and the effective cross sectional area of the armature windings.

Title: Round heat transfer elements - are made from core of baked material, e.g. terra-cotta, with metal surface layer
IPC: F28F21/00
Filed: 1975-09-01
Abstract: A unit for use as a heat-transfer element has a surface which is symmetrical about an axis of rotation. The core is made of a material is baked at high tem. and has good resistance to sudden changes in temp. Around the core is a layer of metallic material applied by rolling the core on the surface of the metallic material while the latter is molten. The element may have a wire or a bar in the axis of rotation fixed in the mass of the core. the core may have cells in it. The surface of the metallic layer is protected against corrosion and may be painted in a colour to indicate its properties. The unit may be used as a heat transfer element. A large number are put into a flue in a boiler. Heat is transmitted by the points of contact of the elements with the wall of the flue and the points of contact between the elements themselves. When the supply of heat stops, the elements continue to heat the water by the heat contd. in the cores. The elements can also be used as rollers, as a means of transferring an electric current and, if in steel, as a magnet. The element is easy to manufacture. It will not sink in the molten melt because the core material is lighter. The metal attaches easily because the core is rough. The core can be prevented from entering the molten metal to far by a wire or a bar passing through the axis of rotation and capable of rolling on the edge of the vessel contg. the metal.

Title: (11)-Amino-vincamones useful as cerebral circulation regulators - prepd. from (11)-nitro-vincamines by reduction and treatment with a base
IPC: C07D461/00
Filed: 1976-01-30
Abstract: 11-Aminovincamones are prepared from 11-nitrovincamines by a process in which, in either order, the nitro group is reduced to an amino group and the vincamine is transformed into a vincamone by the action of a base. A typical prod. is (-) 11-aminovincamone. In an example, this was prepared as follows; 5 g (-)11-nitrovincamine was treated with 1.3 g K tert butylate in anhydrous benzene, refluxing for 6 hours, to give 3.5 g (-)11-nitrovincamone, m.pt. 186-188 degrees C. 3 g of this prod. in 50 ml 78% ethanol was treated with a solution of 200 mg calcium chloride in 0.3 ml water and 6 g powdered zinc. 2 hrs. reflux gave 2.1 g 11-aminovincamone, m.pt. 226-227 degrees C.

Title: Bilateral digital radio communications system - has OR=gate which eliminates one of binary signals and accepts received binary signal
Inventor: LECHEVIN RENE
IPC: H04L5/14
Filed: 1976-07-02
Abstract: A device is used for the bilateral transmission of digital binary signals between radio stations. The stations are equipped with transmitter-receivers. Each station receives a first binary signal transmitted by one or more other station. The first signal is combined with a second binary signal transmitted by the receiving station so as to communicate with the transmitting stations. The resulting signal is tertiary. The device has a first input terminal (1) for the tertiary signal. The signal passes through a rectifying circuit (2, 3) and is applied to an OR gate (5). A second terminal (2) receives the second binary signal from the transmitter of the receiving station. This second binary signal passes through a delay circuit (7) and is also applied to the OR gate (5). The output (8) of the device gives the first binary signal received from the other stations.
