Abstract: 1,238,589. Transistor gating circuits. UNITED AIRCRAFT CORP. 23 Sept., 1969 [13 Nov., 1968], No. 46815/69. Heading H3T. Each of a plurality of switching circuits, Fig. 3, connected to a common output line 14a has its input connected to an amplifier 20, whose output is connected through a switch such as a transistor 40 both to the output line 14a and, through a feedback circuit such as R26, to an amplifier input 30. The transistor 40 is made conductive by a selection signal on line 18a whereupon amplifier 20 acts as a negative feedback amplifier to provide an output at 14a. If T40 is non-conductive then the impedance to ground of the output line 14a is given by R26, R28 and the output impedance of the source 12a. Alternatives to the switching transistor 40 are a pair of opposed diodes (22, 24, Fig. 3, not shown), a F.E.T. (42, Fig. 4, not shown), and a four-diode gate. In another embodiment (Fig. 5, not shown) the feedback (26a) has no resistance and is fed to the inverting input of amplifier (20) as before, but the input signal is fed to the non-inverting input; in this case the impedance to ground of the output line (14a) when the switching circuit is off, is the input impedance of the amplifier (20). A selector switch circuit for driving the selection lines 14a of different switching circuits is described (Fig. 6, not shown).

Abstract: 1303052 Fuel elements UNITED KING. DOM ATOMIC ENERGY AUTHORITY 10 July 1970 [16 July 1969] 35868/69 Heading G6C A method of applying a cladding to a nuclear fuel artefact comprises the laying upon a mandrel of at least one layer of a flexible film of cladding material, treating the film to an extent necessary to give a self-supporting cladding, replacing the mandrel by the artefact and then effecting sintering of the cladding, the dimensions of the mandrel relative to the artefact being such that the cladding shrinks firmly on to the artefact on sintering. The flexible film comprises cladding material powder together with a sufficiency of binder to enable the film to be formed and, when formed, to be shaped at least to a limited extent. The cladding material powder may be an oxide or carbide, or it may alternatively be a metal or alloy. More specifically, the oxide or carbide may be formed from a nuclear material such as U or a non-nuclear material such as Al, Zr or Be. If the cladding material is a metal, it may be Cu, Ni, Fe, Zr, steel or Zr alloy. The sintering may be combined with a reaction, e.g. where the cladding material is Si in the first place, this is converted to Si 3 N 4  by sintering in a N 2  atmosphere. The cladding material is made up with the binder and a solvent into a slurry which is then formed into sheets on a suitable carrier, e.g. a silicone-coated paper. The solvent is then allowed to evaporate from the sheet, which is removed from the carrier as a flexible film. The binder may be a thermoplastic or a thermosetting resin. In a particular example, a fuel element for a fast reactor comprises cylindrical UC pellets coated by the above method with an insulating layer of UO 2 , the resultant fuel rod being inserted in a stainless steel can made by the above method or by any other suitable technique.

Title: Convector heaters

Abstract: 1335214 Gas fired convector heater RICHARD BAXENDALE & SONS Ltd 21 Dec 1971 [23 Sept 1970] 45306/70 Headings F4W and F4S In a gas fired convector heater having a fan 20 feeding air over a heat exchanger 14 above a burner 15, a second fan 22 within the casing collects the combustion products and cool air to feed diluted combustion gases to a flue 22A. The heat exchanger is shaped to provide greater surface contact and has a baffle to reduce the speed of flow of the combustion gases. The burner 15 is supplied with gas through a manual on-off switch, a room thermostat and a solenoid operated high-low valve. An overheat thermostat is mounted within the casing. A spark igniter is connected with a flame sensor and a control box to cut off the electricity supply if the gas fails to ignite when the on-off switch is pressed. The normally closed overheat thermostat is mounted near the gap between the heat exchanger outlet and the inlet to fan 22, but out of the normal flow path of the hot gases. Cooling air normally flows past it, but if the fan fails or the flue is blocked, hot gases reach the thermostat and cut off the gas flow. This thermostat resets automatically, but the flame failure controls cause a manual reset switch to trip, so that the heater remains off. A thermostat mounted at the top of the gap between the heat exchanger and the fan inlet, operates to by-pass the on-off switch when the flue gases reach a certain temperature, so that the fan 22 starts immediately on ignition, but continues to run after the heater has been switched off. On a low output setting, both fans run at a slower speed then on the high setting. A low pressure cut off valve in the gas supply prevents more than a very small amount of gas reaching the burner in the event of failure in which the gas valve is held open. The heater is started on low rating, and automatically switches to high rating if this has been selected.
