Title: Shaft mounting system for low power electric motor - has rotary bearings supporting shaft of rotor with oil-soaked felt pad providing lubrication
Inventor: SEVERIN GUY
IPC: H02K5/167
Filed: 1980-08-13
Abstract: The motor comprises a case (1) housing magnets (2,3) positioned on either side of a rotor (4) mounted on a shaft (5). A collector (6) on the shaft takes current from two brushes (7,8). The rotor shaft is supported by two bearings (10,11) each of which comprises a ball rotating freely in a corresponding socket. The shaft passes centrally through a hole in each of the balls. A spring (14) with projecting pegs grips the ball (11) and urges it in towards its seating (12). In order to hold the rotor in the correct axial position, two clips (15,16) are attached to the shaft. The clips are elastic and grip two annular grooves formed in the shaft on either side of the bearing. Lubrication of the bearing is provided by a felt disc (17) soaked in oil and held in place around the shaft by a cover positioned between the bearing and one of the stops.

Patent FR-2502840-A1 (FR)
Title: Single piece cylindrical cathode heater for electron tubes - has uniform temp. distribution over surface and is in form of mesh of intersecting heater wires
IPC: H01J1/15
Filed: 1981-03-24
Abstract: The cathode is fabricated from a single sheet of a refractory metal such as tungsten. The design allows a uniform temp. distribution over 80% of the cylindrical cathode surface. The metal sheet is formed, by electro-erosion, into a mesh in which individual conducting paths span, in a spiral or straight path, between two terminal rings. The conducting strips cross each other in a regular fashion. The thickness of the strips may increase continuously from the edge terminal to the centre of the span as does the spacing of the crossing points of intersecting strips. This arrangement compensates for the tendency for the central region to be at a higher temp. than the edges. Equipotential horizontal rings in intersect the sets of crossing strips at their junction points in the central region of the cylinder. The thickness of the rings is graded, being larger at the centre than the periphery. The shape of the holes defining the strip dimensions is determined by the profile of the electrode tool head in the electro-erosion process.

Title: Thermoplastic co-polyester prepd. by solid state polymerisation - contg. units derived from bis:(beta-hydroxyethoxyphenyl) sulphone
Inventor: GO SANTOS WONG
IPC: C08G63/80
Filed: 1981-04-13
Abstract: Thermplastic copolyester is made by melt polymerising terephthalic acid or a 1-4C alkyl ester thereof with ethylene glycol and 2-12 mole% bis(4-ketahydroxyethoxy-phenyl)sulphone (I), the total amt. of glycol and (I) being 110-300 mole.%. Melt polymerisation is continued until the polymeric prod. has an intrinsic viscosity of 0.2-0.7 dl/g. The copolymer is then cooled to a solid state, reduced to particles and heat crystallised. Solid state polycondensation is then carried out to produce a copolyester of inherent viscosity at least 0.65 and higher than that of the melt polymerised prod. The copolymer is used to make bottles, melt formed plastic containers, and packaging film for foodstuffs and beverages. It is more resistant to decomposition in the molten state to form acetaldehyde than is the same copolyester of the same or lower inherent viscosity made entirely by melt polymerisation of polyethylene terephthalate PET made by solid state or melt polymerisation.

Title: Arc welding head for narrow deep slots - with wedge-shaped inert gas nozzle on holder for electrode
Inventor: SIDOROV VIKTOR VLADIMIROVICH
IPC: B23K9/02
Filed: 1981-05-20
Abstract: An arc welding head for operating in a deep and narrow slot in an inert gas atmos to weld very thick workpieces consists of a holder for the electrode and for a wedge-shaped nozzle which receives the inert gas. Its sharp edge is turned towards the electrode. At least one horizontal row of holes and vertical rows of them in the side walls and along the bottom are provided for the escape of the arc shielding gas. This eliminates the risk of the nozzle being clogged by splashes of molten metal and of splashes accumulating in the weld pool of molten metal. The weld is of better quality and the productivity is improved.
