Title: Improvements in or relating to radiators for aircraft
IPC: F01P7/10
Filed: 1942-12-09
Abstract: 574,677. Aircraft radiators. NAPIER & SON, Ltd., D., HALFORD, F. B., and HAGG, A. E. Dec. 9, 1942, No. 17497. [Class 4] An annular radiator F for the engine coolant and the oil of an aero-engine is arranged in a passage of conical form, between the cowling A and the engine casing C, having an annular opening just behind the airscrew, a fan H being mounted in the opening. The air after flowing through the radiator, flows around the engine, and part of the air issues through orifices G of casings surrounding the exhaust stubs J. The rest passes on to openings at the rear and the flow is controlled by hinged flaps L controlled by a hydraulic jack L<3> and by similarly actuated flaps controlling exists beneath the cowling. The fan H is preferably driven in the opposite direction to the airscrew. Armour N, N<1> may be arranged outside the cowling and beneath the engine casing to deflect bullets from the radiator. The forward end of the radiator and cowling is supported by adjustable radiating rods from the engine casing. The radiator is in two or more parts which are readily separable to facilitate assembly and dismantling.

Title: Improvements in and relating to noise balancing circuits for signal translating systems
IPC: H03G11/04
Filed: 1943-10-26
Abstract: 575,188. Wireless receiving circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 26, 1943, No. 17624. Convention date, Oct. 31, 1942. [Class 40 (v)] In a noise-reducing system for a signalmodulated carrier-wave receiver, signal-modulated waves are fed from the tuned secondary 15 to the cathodes 19, 20 of a double diode 11. The signal anode 17 has a load resistance 22 ,and H.F. byepass condenser 23. The noise anode 18 feeds a load circuit comprising a resistance 24 and audio byepass condenser 26 in series with a resistance 25 and H.F. byepass condenser 27, the common point of the resistances being earthed. The resistance-capacity combinations 22, 23 and 25, 27 are identical, but resistance 24 is about 100 times as large as resistances 22, 25, and condenser 26 is large compared with condensers 23 and 27. The audio frequency signal is taken from leads 12, that is across anode 17 and earth, and includes the voltages across resistances 22 and 25 in series but of opposed polarity. For normal signals, since resistance 25 is only one hundredth of resistance 24, only one per cent of the audio frequency signal voltage appears across resistance 25; and so 99 per cent of the signal appears across leads 12. Noise impulses, however, are completely byepassed by large condenser 26 and appear across resistance 25 with the same magnitude as across resistance 23, but of opposite polarity, and so do not appear in the output.

Abstract: 991,747. Molecular stills. VITAMINS Ltd. May 3, 1962 [May 12, 1961], No. 17441/61. Heading B1B. In a molecular still comprising a vacuumchamber 2 which contains a plurality of stationary, upwardly-facing, heated evaporator surfaces 30 arranged alternately with a plurality of stationary, downwardly-facing, cooled condenser surfaces 32, the distilland F flows progressively over the evaporator surfaces in filmform, the film of distilland on each evaporator surface being displaced towards the periphery by means of a wiper assembly ; the condensate formed on each condenser surface (except the uppermost) is passed back to the preceding evaporator surface, the distillate product D is withdrawn from the uppermost condenser surface, and the distillation residue R is withdrawn from the lowest evaporator surface. The evaporator and condenser surfaces are the upper and lower surfaces respectively of separate annular plates possessing rims round their central apertures and gutters 50, 51 at their peripheries. Each plate contains passages 40 that can be fed with hot or cold fluid supplied via pipes 42. The wiper assembly for each evaporator surface comprises a rotor 60 with three arms 64 equipped with wiper elements 72, each element being spring-loaded on a vertical spindle. A preferred embodiment of the wiper assembly has upper wiping arms 62 fitted with wiper blades 77 which bear upon the corresponding condenser surface. The wiper assembly of each evaporator surface is fitted with an annular gutter which receives feed liquid from pipes 82 and 84 and delivers it to the evaporator surface via a channel 90 in each wiper arm. All the wiper assemblies are fixed to, and rotate about, the central shaft. During distillation, the film of distilland on each evaporator surface is gradually propelled into the peripheral gutter 50 by the wiper elements, and then this residual liquid flows via line 52 into the feed gutter of the evaporator below, whilst the condensate on each condenser surface is impelled into the peripheral gutter 51 and is then pumped into the feed gutter of the evaporator above via line 53.

Title: Method and apparatus for purging air from internal combustion  engine
IPC: F16K24/04
Filed: 1971-05-28
Abstract: 1358102 Cooling systems for I.C. engines SAF-GARD PRODUCTS Inc 28 May 1971 17789/71 Heading F4U [Also in Division F2] A cooling system for an I.C. engine 10, includes in the return conduit to the radiator 11 a valve body 18, the valve body 18 having a coolant passageway 30 and a valve chamber 31 which is closed by a pressure cap 32. The valve body is interconnected with an accumulator tank 15 by a combined overflow and return line 41. An overflow line 37 is connected at one end through a bottom wall 33 to a pocket 39 at the lower end of the chamber 31, and has its opposite end 40 opening into the air pocket 25 above the top level 26 of tne coolant 23 in the radiator reservoir 24. Within the chamber 31 are two check valves, namely a check valve 50 which opens in a direction allowing flow from the coolant reservoir 24 to the accumulator tank 15 and a check valve 51 which allows flow from the tank 15 to the coolant reservoir 24. In operation when the engine overheats steam and coolant from space 25 is vented by pipe 37 to the space beneath valve 50. Valve 50 is lifted by the pressure and the liquid is allowed to pass via openings 56, the open lower end of stem 46, and the relief tube 41 to the tank 15. When the engine cools a partial vacuum forms in the system and coolant is returned by the atmospheric pressure in tank 15 along tube 41. Valve 51 now opens against the action of a weak restoring spring and the returning fluid is conveyed by pipe 37 to the reservoir space 25. The valve body 18 may be made of transparent plastics material so that the flow of coolant to the radiator may be seen. For topping up the system a liquid fill fitting 70 may be provided having a spring loaded valve normally keeping it closed. In another form (Figs. 7, 8, not shown) the usual filler cap on the radiator is modified and a pipe taken from the filler neck to the tank 15.

[Also in Division G3] In an I.C. engine device controlling fuel injection as a function of engine speed an engine camshaft driven shaft 9, Fig. 1, acts through cam 29, roller 31, tappet 32, bell-crank 35 and spring-loaded tappet 40 to operate fuel injection pump plunger 3. Bell crank 35 and rocker 27 are eccentrically mounted on shafts 38 and 42 which are pivoted to control the stroke of plunger 3. Engine speed is controlled by governor 13 which acts through sleeve 16, cam 17 and arm 25 to pivot rocker 27. A duct 51, Fig. 2, (not shown) leading from a fuel transfer pump acts on a spring-loaded plunger 47 to move cam 58 axially to rotate arm 43, shaft 42 and the pivot 38 of rocker 27 thus adjusting the plunger stroke in accordance with the speed/delivery performance of the fuel injection pump 2. The cam end 45 acts as an abutment for arm 60 which rotates shaft 38 and the pivot 37 of bell crank 35 to move tappet 40 thus adjusting timing of the fuel injection. The rotational position of cam 58 is effected through pinion 55 and rack 56 by barometric capsules. In a modification the control cam has angularly spaced longitudinal tracks which are moved manually into operation to compensate for the fuel viscosity and density. The loading of governor spring 19 is controlled manually through shaft 22 and arm 21, which carries a pin 23 engaging a groove 24 in spring- abutment 20.
