Abstract: 1,185,840. Power plant; driving gear. F. SHIBATA. Aug.11, 1967 [Aug.11, 1966], No. 36888/ 67. Headings F1B and F1Q. The outputs of prime movers 5, 7, Fig.1 are combined by arranging the prime mover 5, to drive the load 8 directly through an electromagnetic coupling 3 whilst the prime mover 7 drives an electrical generator 6 connected to a winding 4 of the coupling so that the coupling also acts as a motor. The prime movers may be I. C. engines, steam turbines, gas turbines or hydraulic turbines. In Fig.1 the prime mover 7 drives an A. C. electrical generator supplying the winding 4 on a primary rotor 2 driven by the prime mover 5 and forming an electromagnetic coupling with a rotor 3 on the output shaft, which rotor may be of squirrel cage type. Alternatively the winding 4 may be associated with the rotor 3. In Fig. 3 the first prime mover comprises a diesel engine 5 whilst the second prime mover 17 is a gas turbine driven by the engine exhaust gases. The generator 16 supplies A. C. to a winding 4 on the rotor 2 and D. C. to a winding 9 on the rotor 3 or vice versa.

Abstract: 444,663. Prepayment mechanism for meters. MEASUREMENT, Ltd., Terminal House, Lower Belgrave Street, London, and CONNOR, R., and CLIFFORD, C. F., Tameside Works, Dobcross, Oldham. Dec. 29, 1934, No. 37244. [Class 27] Switch tripping-mechanism for prepayment electricity meters, allowing of the accumulation of a basic debit charge when the amount prepaid is exhausted, comprises intergeared low and high speed cams in the form of a gapped cylinder a and a half cylinder b engaged by parts d and e of a switch tripping arm c, the high speed cam b always determining the actual tripping of the switch. The tripping arm c is secured to a spindle f carrying a catch spring k for the switch arm n, and when the switch is set, the arm n engages behind the catch k causing the parts d and e of the tripping arm c to be held against the cams a, b against the action of a spring g. When prepayment is exhausted, the parts d and e pass through the cams under the action of the switch arm n, but are at once returned by the spring g with the arm c in engagement with an adjustable stop h as the switch arm n is released by the catch k. As the basic debit charge continues, an upturned part i, at the edge of the gap a<1> in the cam a, engages the part d of the tripping arm c and draws it into engagement with its under surface, the arm c then assuming a position in which the catch k cannot hold the switch arm n until the accumulated debit has been paid, and the part d released from the interior of the cam a. Indicators.-An arm p on a spindle q is engageable by a pin o on the switch arm n to operate an indicating pointer showing whether a credit or debit stands to the consumer.

Abstract: 1356551 Inertia switch GENERAL MOTORS CORP 10 Aug 1972 [23 Aug 1971] 37298/72 Addition to 1350346 Heading H1N In an inertia switch for vehicle crash detection, a movable mass 20, Fig. 1, is retained in a sector-shaped recess 36, Fig. 2, by a permanent magnet 42, the angle of the divergent walls being such that over a predetermined range of crash angles relative to the longitudinal axis of the vehicle, the ratio of the operating crash force to the magnet force is substantially constant. The switch therefore has substantially the same sensitivity over a range of crash angles.

A yarn clearing arrangement in which cutting members 4, 12 cut the yarn on receipt of a cutting impulse includes means 13, 14 for simultaneously clamping that end of the yarn that is approaching the cutting point. As shown the slide 4 is biassed to the left by a spring 9 but is held against movement by a lug 10 of the slide 4 resting against a pin 11. A cutting impulse causes the pin 11 to be retracted whereupon the slide 4 is pulled to the left by the spring 9 to cause the cutting edges 4, 12 to sever the yarn. Simultaneously the yarn end approaching the cutting edges is firmly held between a clamping rod 13 and the lug 10.

Filed: 1955-12-30
Abstract: 820,853. Magnetic compositions. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. Dec. 30, 1955 [Feb. 3, 1955; May 3, 1965], No. 37486/55. Drawings to Specification. Class 38 (2). A magnetic ferrite having a rectangular hysteresis loop, a negative coefficient of magnetostriction and containing substantially equal molecular percentages of oxides of metals in the bivalent and in the trivalent states is made by compressing a mixture of metal oxides including ferric oxide and an oxide of manganese, heating between 1200‹ and 1350‹ C. and cooling slowly in an inert atmosphere. The heating may be for 2-6 hours in nitrogen containing up to 2% by volume of oxygen, and the cooling may be for 15 hours in pure nitrogen. Other oxides of metals in the trivalent state may be of aluminium and chromium, and oxides of metals in the bivalent state may be of magnesium, zinc and cadmium. Suitable limits of proportions of starting materials are given. The percentages of oxides of metals in the bivalent and trivalent states need not be equal, part of the MnO acting as though in the Mn 2 O 3  state after the manufacturing process. The addition of ZnO increases the flux density for a given magnetizing force, and reduces the coercive force, the addition of MgO acts oppositely, without affecting the rectangularity of the loop. The effect of the addition of Al 2 O 3  or Cr 2 O 3  is similar to that of MgO, Fig. 3 (not shown). The mixture must not contain by weight more than 0.5% impurities in general and more than 0.05% of any of SiO 2 , BaO, PbO, and SrO. The oxides are ground in distilled water with iron balls. The compression may be at between 0.5-15.0 metric tons/cm.<SP>2</SP>, preferably 5 metric tons/cm.<SP>2</SP>, giving linear shrinkage of 15% upon sintering. Sufficient shrinkage, between 8 and 30%, is needed to produce mechanical strain. The sintering temperature varies with the constitution of the ferrite, which may also be presintered between 900 and 1100‹ C. and reground. The production of materials is described in which Fc 2 O 3  is associated with MnO; MnO, ZnO; MnO, MgO, ZnO; MnO, MgO; MnO, Al 2 O 3 ; MnO, Cr 2 O 3 ; MnO, MgO, ZnO, Cr 2 O 3 ; MnO, MgO, ZnO, Al 2 O 3 .

The piezo-electric sheet is of greater area than the other layers, and is terminated in a non-reflective absorber, e.g. lead.  Conductive metal plates 14, small in area compared to the resolution of the device, may be included to improve the coupling between the non-linear layer 11 and the electroluminescent layer 13.

Title: Process for reprocessing used uranium fuel
IPC: C01G43/00
Filed: 1965-09-06
Abstract: Spent uranium-containing nuclear fuel is dissolved in a molten salt bath containing ammonium nitrate at a temperature higher than 210 DEG C., the melt is filtered, and the filtrate heated to at least 330 DEG C. to precipitate a uranium compound purified from fission products. The fuel may be pellets of metallic uranium, UO2, UO2-graphite, U3O8, UC, or UC2. Alkali metal nitrates, e.g. KNO3, LiNO3, or NaNO3 are added to the melt either before the dissolving step or after filtering and before heating to precipitate the uranium compound. Alkali metal chlorides, e.g. KCl or NaCl may also be added.  In the dissolving step Kr, Xe, I, and Ru fission products are driven off.  A first filter of quartz or glass fibre removes graphite if present.  A second glass powder filter removes Zr and Nb fission products, and a third filter of calcium oxalate or gamma-alumina removes rare earth fission products. Zr-Nb is recovered as oxalate by treating the glass powder or gamma-alumina with molten KNO3-LiNO3, containing oxalic acid.  Suitable apparatus is described with reference to a drawing.
