Title: Nuclear fuel elements
IPC: G21C3/32
Filed: 1969-08-05
Abstract: 1278799 Fuel elements COMITATO NAZIONALE PER L'ENERGIA NUCLEARE 5 Aug 1969 [20 Aug 1968] 39204/69 Heading G6C A vented fuel element bundle comprises a space provided at the top of the bundle, a plurality of small tubes whereby the released fission gases are conveyed towards the upper section of the space, and means for conveying these gases from the lower section of the space to the exterior of the fuel element. Each fuel rod 1 in the bundle consists of a metal tube 9 housing nuclear fuel 8, fertile material 11, 14 and a porous medium 12, with a space 10 between the fuel 8 and fertile material 11 for allowing for fuel expansion and for receiving condensed fission products. The upper end of tube 9 is connected to a capillary tube 3 by means of an adapter plug 13. In one embodiment, shown in Fig. 8, fuel rods 1 are housed in a duct 2 of hexagonal cross-section beneath a chamber 32 of toroidal form for collecting the gaseous fission products. Two passages are provided for a liquid metal coolant flow: one is between the duct 2 and the outer wall of the chamber 32; the other passage 33, which has the profile of a Venturi tube, is defined by the inner wall of the chamber 32. A plurality of apertures 28 are provided at the narrowest section of passage 33. The capillary tubes 3 pass through the bottom of the chamber 32 and extend to the top of the chamber. Gaseous fission products flow from chamber 32 through the apertures 28 and are removed by the small portion of the coolant which flows through the passage 33. The latter by means of a tube 30 communicates with a part of the cooling system where the gases are separated from the liquid metal coolant. The dimensions of the chamber 32 are such that, in any predictable transient conditions, the coolant level within the chamber will never reach the upper ends of the tubes 3.

Patent GB-1516027-A (GB)
Title: Automatic signal level control circuit
IPC: H03G3/34
Filed: 1976-09-24
Abstract: 1516027 Automatic signal level control circuit GRUNDIG EMV 24 Sept 1976 [26 Sept 1975] 39839/76 Heading H4R An automatic signal level control circuit of the type shown in Fig. I in which a threshold circuit is supplied with the rectified output voltage of the control amplifier, the threshold circuit output feeding a capacitive store C whose voltage is used to control the control amplifier via setter D, has means for reducing the effect of interference pulses on the voltage stored in C comprising a store control circuit G, (branches I-IV Fig. 2). In the absence of circuit G an interfering pulse entering at F will pass through a diode at A causing a positive pulse on base of transistor 10 and a negative pulse on collector 10a, which passes via diode 12 to the storage capacitor 14, thereby reducing the stored voltage and causing a change in the control amplifier gain. With the circuit G, the negative pulse on 10a reduces the voltage on capacitor 17 via diode 24. Base drive for transistor 23 is via diodes 25 and 26, and for an interfering pulse of small magnitude, the reduction of voltage on capacitor 17 is insufficient to reverse bias diode 25, and thus the contribution to the base current oftransistor 23 via diode 25 is reduced in accordance with the magnitude of the interfering pulse, causing an increase in voltage on the collector of transistor 23, which results in a positive pulse being fed via diode 29 to capacitor 14 thereby tending to neutralize the negative interfering pulse. For large interfering pulses, diode 25 becomes reversed biased and so the base current to transistor 23 is limited to that flowing through diode 26 but does not drop below that value. Thus in this case the interfering pulse is only partly neutralized and the voltage on capacitor 14 can change and adjust the gain.

Title: Improvements in or relating to hydraulic control and engine starting systems
Inventor: CHURN CHARLES REGINALD
IPC: F16H39/02
Filed: 1963-10-16
Abstract: 1,032,197. Helicopter control systems. WESTLAND AIRCRAFT Ltd. Jan. 11, 1965 [Oct. 16, 1963], No. 40763/63. Headings B7G and B7W. [Also in Division F1]  An engine is started by an hydraulic motor which can thereafter act as an hydraulic pump driven by the motor and supplying hydraulic fluid under pressure. Fig. 1 shows an hydraulic system for a helicopter, comprising a variableangle swash-plate pump 1 driven through a gear-box 2 and free-wheels 3, 4 by either an auxiliary power unit 5 or a drive 6 from the helicopter rotor head. When one of the helicopter engines 27, 28, 29, 30, e.g. the engine 27, is to be started, the corresponding selector valve 23 is moved to a position in which the pump 1 (driven by the auxiliary power unit 5) is connected to an hydraulic pump 33 to drive the latter as a starter motor for the engine. When the engine 27 has been started, the selector valve is moved to the neutral position shown to shortcircuit the pump 33 so that it does not absorb any appreciable power while the engine is attaining idling speed. The other engines can be similarly started, but in this case, the pump 1 can be driven by the engine or engines already started, through the rotor head and the drive 6. Once an engine, e.g. engine 27, has reached idling speed, its selector valve 23 is moved into a position in which the shortcircuit is removed from the engine's pump 33, whereby the pump energizes the wheel brake system 44 through conduits 45, 46. Enginedriven pumps 33, 37 have separate accumulators 42, 50 respectively, but share a common header tank 40. Pump 37 supplies hydraulic power to the undercarriage system 52, rotor blade folding system 53, rear door operation 54, hydraulic winch 55 and rotor brake system 56, and provides an alternative supply to the wheel brake system 44. Forward and aft cyclic pitch control jacks 15, lateral cyclic pitch control jacks 16 and collective pitch control jacks 17 can be supplied either by the pump 1 through lines 14, 18 or by the engine-driven pumps 38, 39 through lines 63, 64. Pumps 38, 39 share a header tank 57 and an accumulator 58. In an emergency or for test purposes, selector valves 20, 21 enable the pump 1 to supply the systems normally supplied by the pumps 33, 37, or allow the systems 15, 16, 17 to be supplied by the pumps 33, 37. The invention may be applied to engine-driven equipment such as cranes, earth-moving equipment and farm machinery including tractors, the hydraulic fluid for operating an hydraulic pump as a starter motor for the engine being held in an accumulator.
