Filed: 1972-09-25
Abstract: 1412146 Thrust-producing mechanisms D O ENIOJUKAN 20 Sept 1973 [25 Sept 1972] 44189/72 Heading F2X A thrust-producing mechanism comprises means for causing a mass to move continuously round an endless path which, along a major part of its length, is curved about a centre of curvature which is located outside the endless path, and a rotatable drive means for propelling the mobile mass round the endless path. In one embodiment, a casing block is formed of two dished halves 1 held together by edge flanges 3 to form between them a shallow cylindrical chamber. Grooves are formed in the opposing faces of the block halves 1, each groove comprising an upper curved portion 6 and a lower curved portion 7 joined at their ends by loop portions 8. The centre of curvature of each groove portion 6, 7 lies outside the endless channel formed by the groove portions 6, 7, 8. Rollers 9 are located in the endless channel, being paired by shafts 10 between opposite rollers in the two block halves 1. Each block half 1 has a centrally bored outer hub and on a shaft 11 extending through, and rotatable in, bearings in the hubs is fixed a disc 13 located in the shallow chamber within the casing block. The disc 13 is formed with a plurality of radial slots 14 through each of which passes the shaft 10 of a pair of rollers. The disc 13 is rotated by an external power source applied to the shaft 11, and the rollers 9 thus caused to move around the shaft 11. During the parts of their motion following groove portions 6, 7, centrifugal forces are directed radially from the centres of curvature of these portions 6, 7, and these force combine to a resultant force, applied by the rollers 9 to the casing block in a direction defined by a line joining the centres of curvature of the portions 6, 7 and the axis of the shaft 11.

Apparatus for serving rotation of a body 1 comprises a driving element 14 coupled to the body 1 so that rotation of the body 1 causes rotation of the driving element, a driven element 18, which in the embodiment described is a magnet, the element 14 comprising magnetic material in the embodiment described although these may be reversed. The driven element 18 is mounted within the ring element 14 so that magnetic flux extends from the magnet into the magnetic material. The magnetic material has an intrinsic coercive force of magnitude sufficient to ensure that a substantial force is required to effect relative movement between the magnet and the magnetic material. The shaft 17 of the driven element has an actuating member 19 mounted thereon which by engagement with a lever 36 prevents the driven element from rotating in a sense corresponding to rotation of the body in a predetermined direction. Upon rotation of the driven element in the opposite sense, the actuating member 19 engages the lever 36 in a different position which gives a signal to the microswitch 32. The driving element 14 is mounted in a casing 6 which is secured to the shaft 1 by means of a screw 12. The lever 36 is pivoted on a plate member 22 which is biased in a anti-clockwise direction by a spring 26 but can be rotated in an opposite direction by a knob 24. After the micro-switch has been operated knob 24 is rotated clockwise and then released to bring the actuating member 19 and the lever 36 back to the initial position.

Thickness faults in a running textile yarn are detected by an electro-optical head and classified in respect of their length and thickness, the faults in the different classes being counted. A plurality of heads have their outputs sequentially gated to the classifying equipment by a shift register and F. E. T. s, the former being driven by a multivibrator generating 10 KHz to 1MHz which is stopped on the dentification of a fault. Thickness signals in respect of thicknesses exceeding 180% stip shift registers SHR L0-L3 , Fig. 2, according to their lengths or duration as determined by pulses produced by Schmitt triggers TR1  L0-L3 , which have different predetermined time constants, and shift registers SHR in accordance with their amplitude D1-D3, to operate a counter selected by one of the gates G LOD1  - G L3D3,  at the conclusion of the fault signal, the counter operating signal serving after a delay also to reset the shift registers, and discharge the amplitude measuring condensers. A count is only gated if a 180% pulse, a defect pulse (200%, 300% or 450%) and, a length class signal are simultaneously received and thickness faults having parts below the predetermined fault threshold are gated as a single length by circuitry described with reference to Fig. 15 (not shown). A measuring head may comprise a plurality of photoelectric measuring arrangements, three mutually at 120 degrees, three at 60 degrees or two at 90 degrees, each arrangement comprising a gallium arsenide diode infrared source 64-66 Fig. 3 directing a beam across the filament 67 to a group a - e of silicon junction photo-cells 61-63 which are dimensioned to cater for different predetermined fault thicknesses and the outer cells of which are connected through an integrating circuit of long time constant to form a light intensity reference signal. The sources of the arrangements are sequentially switched by a switching device through a shift register and F. E.T. gates, and may comprise incandescent or quartz iodine lamps. The system may include Kerr cells and polarizing filters for chopping the beams. Spinners doubles exceeding 130% thickness may be monitored in a separate circuit and alternative resistors may be switched into "fault length" classification circuits to cater either for worsteds or for cottons and wools.

Abstract: 1,132,962. Processing reflected signals. SEISMOGRAPH SERVICE (ENGLAND) Ltd. 15 Nov., 1965 [13 Nov., 1964]. No. 46449/64. Heading H4D. Undesirable multiple reflection components of a reflected signal are attenuated by a system comprising a correlator included in the signal feedback path of a feedback loop, a signal applied to the correlator being cross-correlated with the reflected signal reversed in time. The invention is applicable to deep echo sounding, ultrasonic flaw detection, ionospheric sounding and seismic reflection systems. In the embodiment illustrated by Fig. 8, a seismic field record is first played backwards through stage 4 into an input 7 of correlator 8 (switches 9 and 10 being in the positions shown) and recorded in the correlator as a reference trace. The field record is then played forwards into the correlator 8, switches 9 and 10 being in their alternative positions such that the cross-correlation output of correlator 8 is fed back to the input of stage 4. The output of stage 4 is coupled to a recorder 5 to provide a record from which, it is stated, all multiple reflections involving the ground surface have been substantially eliminated, but in which desirable multiple reflections involving only subsurface formation boundaries (which tend to reinforce primary reflections) are retained. The effects of time and amplitude errors in the field record, and their compensation, are discussed. Prior art systems involving feedback for the elimination of multiple reflections are described (Figs. 1 to 7, none shown). The correlator (Fig. 12, not shown), may be of the type described in Specification 1,111,331, comprising an elongated correlator head (23) of magneto-resistive material, a tape loop (21) on which is recorded the reference trace and which is held stationary during the correlation process, and a moving tape loop (22) on which is recorded the signal to be correlated with the reference trace.

Abstract: A material suitable for use as a control element in nuclear reactors comprises particles of a boron containing material such as B, B4C or Zr B2, coated with Ti C, dispersed in a metal matrix. The metal matrix may be stainless steel, Fe, Co, Ni, Cr, Zr or their alloys and the matrix may also contain the carbides of W, Ti or Ta.  The boron containing particles are preferably first coated with Si C by a fluidized bed process in which hydrogen and trichloromethylsilane or a mixture of methane and silicon tetrachloride is passed through a bed of boron particles 10 - 3000 microns in diameter at 1000 DEG -1700 DEG C.  The Ti C coating is also formed in a fluidized bed process from a mixture of hydrogen, toluene and titanium tetrachloride. When Zr B2 is used a first coating of carbon is applied prior to the Si C coating.  The coated particles are then mixed with the powder of the metal matrix e.g. Co, cold pressed and sintered at 1300 DEG -1800 DEG C. Alternatively hot pressing, swaging, rolling or extrusion may be used.
