Title: Improvements in electric system employing space discharge devices
IPC: H03C1/22
Filed: 1924-10-17
Abstract: 247,626. Western Electric Co., Ltd., (Western Electric Co., Inc.). Oct. 17, 1924. Thermionic detectors and modulating systems. -Consists in inserting an impedance in the grid circuit, of a modulating, demodulating or detecting valve, such that during that part of the cycle of the impressed wave which tends to make the grid positive the grid current produced causes a drop of potential across the impedance which drop tends to maintain the grid at its normal value. In the system shown in Fig. 1, the impedance is an ohmic resistance 14 in the grid circuit of the valve 10. The effect of this impedance is to change the top of the normal characteristic curve of the valve to the shape shown in dotted lines in Fig. 3. In the system shown in Fig. 2, the impedance is a valve 18 having its cathode 19 connected to the cathode of the valve 10 and its plate and grid connected together to form an anode which is connected in series with the secondary of the transformer 15 and the grid 13 of the valve. When the impressed oscillation tends to make the grid 13 positive, the valve 18 is a high impedance to the flow of grid current so that the potential drop is substantially wholly across the valve 18. This arrangement causes the top of the normal characteristic curve of the valve to be cut off as shown by the horizontal line in Fig. 3. In the system shown in Fig. 4, the impedance in the grid circuit of the demodulating valve 30 is the secondary winding of the transformer 39 the impedance of which, at the frequencies dealt with, is such as to match the valve impedance between grid and cathode when the grid is negative. The invention is also shown and described applied to systems in which two valves are connected in known balanced relation with respect to carrier and modulating waves impressed in the input circuit and from which side bands only are delivered to a load circuit, the impedance being inserted in each grid circuit. In another modulating system, Fig. 8, a by-pass circuit is associated with the carrier wave. source 72 and the output circuit, whereby energy is transferred by a transformer 82 to the output circuit in out of phase relation with the unmodulated component passing through the valve 80, so that the amplitude of the unmodulated carrier wave is substantially reduced.

Abstract: 987,165. Filling bags. P. CROSA. June 21, 1963, No. 24833/63. Heading B8C. A process for filling containers, e.g. bags, with textile fibres by pneumatic means is characterized by the fact that the exhaust-air flow discharged by the conveying means is intermittently interrupted to provide an " airhammer " resulting in compressing forces which exert a packing effect on the stowed fibres. The fibres are conveyed through a conduit 4 by a continuous air stream into a foraminated funnel 5 the conveying air escaping through the apertures in the funnel to the inside of a casing 1 and the fibres falling into a bag held by a filling nozzle (not shown) fitted to the base 3 of the casing 1. The conveying air is discharged through a conduit extending from a cover-plate 2 and having interposed therein a butterfly valve 7 the spindle of which carries a crank 8 acted upon by a double cam 9 which is continuously rotated. As the boss of each cam 9 engages with the crank 8 the butterfly valve is opened and on disengagement the valve sharply returns to its closed position, thus creating the " airhammer " effect.

Abstract: 987,164. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 21, 1963 [June 23, 1962], No. 24860/63. Heading G6C. [Also in Division H2] A system for transmitting an electrical signal from jacket to jacket in a nuclear reactor wherein fuel elements are mounted singly or in groups in jackets which are disposed end to end in a fuel channel comprises, at each junction between two jackets across which an electrical connection is to be carried, collector rings or ring segments on one jacket and resiliently mounted contact studs on the other jacket adapted to make electrical contact with the rings or ring segments solely on account of juxtaposition of the jackets, the collector rings or segments and contact studs being mounted against the inner or outer surfaces of the side walls of the jackets or within the thickness of these walls. In the embodiment shown in Fig. 2 in which the signal from a thermocouple 12 is transmitted along a fuel channel 2 containing fuel elements 4 housed in jackets 3, 3 1  (the jacket surrounding the thermocouple 12 being referred to by the numeral 3 1 , the remainder by the numeral 3), the upper end of each jacket has two collector rings 8 fixed rigidly to an insulating ring 13 itself mounted in a metallic ring 22 fixed in the bore of the corresponding jacket. At the lower end of each jacket 3 studs 7 are mounted on the ends of flexible longitudinal strips 14 riveted at 15 through an insulating pad 16 to a small metal plate 23 fast with the jacket 3, the rivets being insulated from this plate. The column of jackets 3, 3 1  is surmounted by a jacket 25 (Fig. 1 not shown), perforated laterally to permit the circulation of cooling fluid and capped by a plug. The electrical connection between the rings 8 of the top jacket 3 and the exterior of the plug is effected in any desirable manner, e.g. by means of studs and wires as above described as far as the plug and then by means of wires passing through a tightly sealed passage through the plug. It is possible to transmit simultaneously several signals, corresponding for example to the temperatures at several points along the channel 2, by dividing up the rings 8 into as many segments as there are signals and associating one or more studs 7 and strips 14 with each segment. In an alternative embodiment (Fig. 4), the collector rings 8 are mounted in the thickness of the upper edge of each jacket 3, 3 1 , being inserted in an insulating ring 17 which is fitted into the edge, and the studs 7 are carried by flexible radial strips 18 riveted at 19 to the bottoms of grooves formed radially in the lower edge of each jacket 3. An insulating member 20 prevents the studs 7 shorting to the wall of their jacket 3. Specification 954,777 is referred to.
