Abstract: 1,229,018. Fuel elements. ALLMANNA SVENSKA ELEKTRISKA A.B. 3 Sept., 1968 [4 Sept., 1967], No. 41815/68. Heading G6C, A fuel assembly comprises a polygonal sheath 1 housing a bundle of parallel fuel rods 5 and spacer elements 10<SP>1</SP> helically wound around some or all of the fuel rods 5 in the same direction and with the same pitch, the fuel rods 5 being of two different types, A and B, each fuel rod B carrying one spacer element more than each fuel rod A, each fuel rod A (except those at the sides of the bundle) being surrounded and supported by six fuel rods B while each fuel rod B (except those at the sides of the bundle) is surrounded and supported by six fuel rods arranged so that they are alternately of type A and type B. As shown, the spacer elements 10<SP>1</SP> are of wire and each fuel rod B carries a single wire, the fuel rods A carrying no wire. The wire is attached to the fuel rods B only at the ends of the wire and under a certain pre-stress. In alternative embodiments, the spacer elements may comprise fins integral with the cladding tubes 7 of the fuel rods 5, and each fuel rod B may carry two spacer elements and each fuel rod A one spacer element. With the embodiment shown, the fuel rods which are not wound and which are situated at the sides of the bundle are supported against the wall of the sheath 1 by means of pellets 12, e.g. in the form of spheres 12<SP>1</SP>, semi-spheres 1211 or spherical segments 12<SP>111</SP>, threaded on to wires 11 disposed parallel to the fuel rods, or alternatively by means of depressions 13 in the wall of the sheath 1. Each group of three adjacent fuel rods encloses a subchannel for the flow of coolant and the helical spacer elements considerably improve the interspersion of the coolant in and between the sub-channels. Each fuel rod carries a narrow resilient pin arranged as an extension of the fuel rod, the free end of the pin being attached to the grid plate (not shown). The assembly is carried out by first inserting the fuel rod extensions in the grid plate and welding them in position, a bundle thus being obtained which diverges from the grid plate towards the free ends of the rods. The bundle is then compressed from the sides with the aid of pressure plates and the space within the bundle is filled with a medium which can be solidified at a temperature at which the fuel rods are not damaged and which is also easy to remove, e.g. an aqueous solution of cane sugar or glycerine. Low m.p. metals and alloys, e.g. Na, K or type metal, or certain plastics may also be used. When the medium has solidified, the pressure plates are removed and the bundle is inserted in the sheath. The medium is then removed and the grid plate attached to the sheath.

Abstract: 1,264,131. Frequency dividers. WYVERN CHURCH ORGANS Ltd. 6 May, 1969 [6 Feb.., 1968]; No. 5864/68. Heading H3T. [Also in Division G5] A frequency divider receiving an input sawtooth at 14 includes a capacitor 5 charged through a resistor 3, a second cpacitor 12 charged through a second resistor 13 and the resistor 3 to the potential at the junction of R3 and C5, and a switch such as a transistor 1 which discharges the capacitor 5 to terminate one sweep of the output sawtooth when the voltage across the second capacitor C12 reaches a certain value. The rate of charge of capacitor 12 depends upon the voltage at the collector of T1 and upon the' input sawtooth, as well as upon circuit valves, the resistor 13 being adjustable. The negative going edges of the input sawtooth repeatedly discharge, at least partially, the capacitor 12 and maintain T1 OFF until the collector voltagehas risen high enough for the capacitor 12 to charge sufficiently rapidly to turn ON T1 during one sweep of the input sawtooth. The number of cycles of the input sawtooth which occur before T1 turns ON is 2 in the described embodiment, giving a frequency division of 2. A plurality of these dividers may be connected in cascade and fed from an oscillator, and used in an electronic organ. The output sawtooth is differentiated at 6, 7.

Abstract: 1290895 Drawing glass fibres OWENSCORNING FIBERGLAS CORP 16 Dec 1969 [8 Jan 1969] 61258/69 Heading C1M Glass fibres are produced by drawing and attenuating filaments from a molten source and inducing into the filaments variations in thickness, which variations are controlled in amplitude, frequency and cyclic repetition. A strand 22 is collected as a wound bundle 32 on a winder 40, the strand being moved back and forth along the length of the package by traversing means 42. As the strand winds on the rotating bundle its speed varies and as a result undesired cyclic dimensional variations are produced along the length of the filament. Located between the bundle 32 and a gathering shoe 24 are means 50 comprising a signal generator 52, drive unit 53 and an arm 54 for introducing perturbations to modify the cross-sectional dimensions of the glass filaments. The frequency of the signal generator is chosen to introduce dimensional variations into the filaments in sufficient number to conceal the presence of the variations due to the operation of the winder 40.

Abstract: 1296809 Automatic phase control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 July 1971 [31 July 1970] 35399/71 Heading H3A In a clockpulse synchronizing system of the type in which local clock pulses are produced by a pulse oscillator 3 feeding a divider chain 4, 5 and in which synchronization is effected by controlling the rate at which pulses are fed to divider 5, the control circuit 12 comprises: an integrator 13, e.g. a counter, which produces output pulses at zero transitions of the integrated input signal 7 with which the local clock is to be synchronized; a comparator 14 for phase comparing these output pulses with the local clock H derived from counter 5 to produce correction signals; and a correction circuit 6 which varies the rate at which pulses are fed to divider 5 in dependence on the correction signals. A second control loop 11 is provided for applying a.f.c. to the oscillator 3. The integrator, Fig. 3a, comprises two up/ down counters 21, 22 which are periodically reset by pulses from divide-by-two stage 4 of Fig. 1, the intervals between being reset being equal to 1¢ clock pulses H. The two counters count up or down depending on the polarity of the data signal pulses applied at 19 and are arranged to operate on odd and even transitions of the data signal respectively. Provided that the up and down counts have exceeded limits defined by 28, 29 or 30, 31. The zero transition within each integration period is detected by 26 or 27, and is fed to output 39 via AND gates 35 or 36 and OR gate 34. Phase comparison and correction circuit. Fig. 5. Pulses from the integrator are applied to a pulse generator (not shown) which produces a fixed number of output pulses for each input pulse, and these are applied to an up/down counter which is switched from an up to a down count by transitions in the clock signal. If the phasing is correct, the up and down counts are equal, if they are not, a residual positive or negative count will remain at the end of each counting period. When this mean value exceeds a predetermined positive or negative threshold, an output is produced on G A  or G R . With no signal on G A  or G B , the output pulse rate Rp is the same as the input pulse rate R B  from divider 4 of Fig. 1, a signal on G R  reduces R p  by inhibiting pulses, and a signal on G A  increases R p  by adding pulses.
