Abstract: 1,001,138. Yielding clutch hubs. BORGWARNER CORPORATION. Nov. 20, 1962 [Dec. 7, 1961], No. 43908/62. Heading F2U. The usual tangential apertures in a hub flange 3, Fig. 1, straddled by connected rings 5, 11 fast with a friction clutch disc 4 and formed with similar apertures to receive helical cushioning springs 16, each have their arcuate outer surfaces 22, Fig. 9, traced out by a radius R having its centre O<SP>11</SP> offset from the hub axis, so that one end, e.g. the left-hand end, of the arcuate surface 22 is nearer to the hub axis than the other, right-hand, end, while the arcuate outer surfaces 18, 21 of each pair of coacting apertures in the rings 5, 11 are arranged the other way round, viz., with their right-hand ends nearer to the hub axis than their left-hand ends. Thus the outer surfaces 18, 21, 22 of each set of apertures coact in scissors-like manner under varying torque loading of the hub, and the frictional engagement with consequential vibration dampening between the cushioning springs 16 and the outer surfaces of the apertures remains substantially constant under all conditions, both of load and speed.

Title: Apparatus for measuring the speed of light
IPC: G01J7/00
Filed: 1972-09-27
Abstract: 1436314 Measuring velocity of light R BARR 27 Dec 1973 [27 Sept 1972] 44558/72 Heading G1A The velocity of light in a medium is measured by modulating a light emitting diode at a frequency in the VHF range, passing the light through the medium to a detector and determining the phase difference between the light emitter modulation signal and the detector signal using a heterodyne technique to convert both these signals to a low frequency. The phase difference is determined for two different values of the optical path length and the values of the change in phase difference, the charge in path length and the modulation frequency are utilized to calculate the velocity of light.  As shown, a VHF oscillator 1 operating at 50 MHz modulates the light emission from an LED2, the light (visible or IR) from which passes via reflectors 4 to a detecting diode 3, lenses 5 being included to provide a parallel beam. The optical components are mounted on a conventional optical bench enabling changes in the path length to be measured. The output of the detector and a reference signal from the oscillator 1 are heterodyned with the output of an oscillator 6 operating at 50.02 MHz and the low frequency (20KHz) components are extracted by band pass filters. The phase difference between the high frequency signals is maintained by the heterodyning so that a measurement of its value can be made using a phase meter 8 or by displaying Lissajous figures on a CRO 9. The optical path length is varied and the change in phase difference measured, or, in the case of Lissajous figures the path length is varied between two known phase difference displays. The frequency of the oscillator 1 is determined for example by using digital circuits to divide it down to such an extent that it can be measured by a stop clock and mechanical counter. The mirrors 4 may be omitted and an in-line arrangement used. The velocity of light in transparent media such as water can also be determined.

Title: Process for the fabrication of nuclear fuel elements
Inventor: MOREAU CLAUDE
IPC: G21C3/62
Filed: 1969-09-10
Abstract: 1,206,559. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 10 Sept., 1969 [23 Sept., 1968], No. 44649/69. Heading G6C. Fuel elements, in particular for high temperature, gas cooled, pebble-bed reactors, are made by coating refractory nuclear fuel particles 4 with a layer of graphite by spraying with a mixture containing the graphite and an organic diluent; forming a "green" jacket 2 by shaping and drying a paste formed of graphite powder and a binder; filling the jacket 2 with the coated particles 4; closing the jacket with a plug 8 formed of the same paste; and baking the jacket and impregnating it with pyrocarbon in a single operation by heating to between 850 and 1100 C. in a gaseous hydrocarbon atmosphere. In the embodiment described, the fuel particles are sprayed with a mixture of micronized natural graphite, coal tar pitch and benzene during agitation in a rotating drum. The particle size is preferably within the range 100 to 400 Á. After coating, the benzene is removed by evaporation, a small proportion of graphite powder (passing a 100 Á aperture screen) is added to the particles, and the particles and graphite are introduced into the jacket and lightly compacted. The graphite powder for the jacket is of standard nuclear-grade and passes a screen having a mesh size of 80 Á. When the fuel permits the use of an aqueous binder, this is advantageously a dispersion in water of polysaccharides, mucilages, starch or alginates. In the case of an organic binder which must be used with hydrolyzable fuels, a drying oil (linseed oil or china wood oil) or ethylcellulose dissolved in a volatile solvent (ortho-dichlorobenzene, benzene or toluene) is used. The fuel particles comprise the oxides, carbides or nitrides of U (enriched) or Pu. The impregnation step may be effected by heating in a flow of natural gas having a methane base at 950 C. for 300 hours, following degassing in a partial vacuum at 500 C. The binder is thereby carbonized and mostly eliminated, and the pores of the jacket and the voids in the mixture of coated particles and graphite are filled with a deposit of pyrocarbon. The resultant cylindrical fuel element is placed within the bore of a graphite sphere or shell 6, the bore then being sealed by means of a graphite plug 10 which is screwed in position and bonded with furfuryl resin. The fuel element may alternatively have a tubular instead of a cylindrical shape (Fig. 2, not shown).

Abstract: 456,926. Zeroizing-mechanism. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Underwood Elliott Fisher Co. ; 342, Madison Avenue, New York, U.S.A.) Aug. 9, 1935, No. 22497. [Class 106 (i)] Zeroizing is effected by simultaneously rotating and shifting axially the shaft carrying the totalizer-driving pinions, both movements being caused by the same interengaging driving members. A lever 25 is rocked manually, first anti-clockwise and then clockwise. The lever drives a segment 26 engaging a pinion 33, Fig. 5, secured to the shaft 18 carrying the driving pinions 6 for the numeral wheels 3. A cam 35, Fig. 8, is attached to the segment 26 and during the initial movement of the segment the end 36 of this cam engages a cam-shaped tooth 34 on the pinion 33 to slide the pinion and shaft axially. Projections 20, Fig. 3, on the shaft 18 are thus moved from the position shown in Fig. 12 to that in Fig. 13 with respect to pawls 23 pivoted inside the pinions 6 and controlled by springs 24. During the continued movement of the segment 26, the shaft 18 is held in its adjusted axial position by the cam part 35 and continues to be rotated by the pinion 33 whereby the projections 20 engage the pawls 23 and restore the numeral wheels to zero. At the end of the return movement of the segment 26 the shaft 18 is restored to its normal axial position by a cam 38 secured to the segment and co-operating with the side 37 of the pinion 33 and with a fixed member 40. The shaft is thus locked in its normal position. The rotation of the shaft 18 is slightly greater than 360‹. Specification 262,919, [Class 106 (i)], is referred to.
