Filed: 1970-06-15
Abstract: 1,262,414. Deflecting propulsion jets. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. 15 June, 1970. [23 June, 1969], No. 28977/70. Heading B7G. A jet deflecting device for controlling an aircraft comprises a truncated spherical nozzle having peripheral openings 2 on the pitch and yaw axes and a co-operating vectoring nozzle 3 also having similarly disposed openings and rotatable on the first nozzle such that on vectoring the nozzle 3, a larger aperture is presented by the openings for the passage of exhaust gases on the side towards which the nozzle is vectored than on the opposite side. In normal flight with clam shell doors 5 open, (Fig. 1, not shown), the openings act as ejectors by inducing ambient air into the gas stream, movement of nozzle 3 vectoring the jet thrust, but when the doors 5 close off the throat as shown, thrust reversal occurs, the vectoring of the nozzle then controlling the direction of thrust through the nozzle openings. Vanes 6, 7 adjustable by pilot or automatic control may be provided in the openings for the further directional control of exhaust gas efflux.

Title: Heat-treating cellulosic materials
IPC: D01F9/16
Filed: 1964-07-14
Abstract: Fibrous cellulosic material is treated to cause substantial decomposition and carbonization by contacting it with an organic or semi-inorganic fluid heated to a temperature between 250 DEG  and 400 DEG  C., said fluid being normally liquid at pressures less than 200 p.s.i.g. and at the temperature employed, substantially thermally stable over the temperature range employed and substantially unreactive toward the cellulosic material, and subsequently heating the material in an inert atmosphere to a temperature above 600 DEG C.  In the initial carbonization, the material may be moved through the fluid either continuously or batchwise and the fluid may initially be at ambient temperature, or may have been previously heated to 250 DEG  to 400 DEG  C.  Figs. 1 and 2 illustrate continuous embodiments of the invention. Material in filament or cloth form leaves roll 1 and enters bath chamber Z which consists of compartments 3, 4, 5 and 6 maintained, e.g. at 280 DEG , 300 DEG , 320 DEG  and 350 DEG  C. respectively. Cylindrical bearings, guides or rollers 7 guide the material through the compartments. Oil seal troughs 8 and 8a, cooled, e.g. by coils, separate hot fluid from cooler fluid in Fig. 1, the treated material being cooled in 8a.  The first and last portions of chamber 2 in Fig. 2, in combination with bearings 7, cooling coils 20 and air gaps 21, serve the same purposes <PICT:1073343/C1/1> <PICT:1073343/C1/2> as the oil seals in Fig. 1. The least practical total immersion time is about 5 minutes. Different fluids may be used in each compartment and their temperature may range from ambient in 3 up to 400 DEG  C. in 6. Other embodiments include (a) placing the material in a vessel, adding the fluid and heating it, (b) passing the material continuously through a single tank of fluid, the tank being large enough for the material to attain the temperature of the fluid and (c) allowing a fluid to vaporize and condense upon the material. Specified fluids include hydrocarbons, e.g. anthracene, halogenated hydrocarbons, fatty acids and mixtures thereof, silicones and silicone fluids or resins, glycerol and glycerine.  The fluid may be extracted prior to use of another fluid or prior to the second stage heating process, which may comprise, e.g. baking at 800 DEG  C. or baking followed by graphitizing at 2000 DEG  to 3000 DEG  C.  The cellulosic material, natural or synthetic, particularly rayons, may be in the form of strands, skeins, ropes or fabrics.

Abstract: 715,835. Heating air; cooling systems for internal-combustion engines. SMITH & SONS (ENGLAND), Ltd., S. Dec. 30, 1952 [Dec. 13, 1951]. No. 29212/51. Classes 64(1) and 64(3) Air is passed into a vehicle interior but may first be heated, selectively, by the engine coolant in a heat-exchanger 20 or by an independent heater, e.g. the wall of a combustion chamber 23, or by both heaters, the exchanger 20 having a valvecontrolled by-pass 33 for the air or for the coolant, Fig. 2 (not shown). A blower 9 draws fresh air into a housing 1 through an inlet 12 and it passes through an annular passage 3, around an inner housing 2 containing the combustion chamber 23, to an outlet 19 leading to the vehicle interior. The housing 2 contains a fuel pump 7 and jet 15, an ignition filament 18 and a centrifugal fuel distributer 6. Combustion air is drawn in from outside the vehicie through an inlet 10 by a blower 5 and exhausted through an outlet 11, from the combustion chamber 23 formed by a frusto-conical wall 14. The shaft 4 of a two-speed electric motor 13 which drives the fuel pump, blower 5 and fuel distributer also bears a water impeller 8 (in the engine coolant circuit to the heat-exchanger 20) and the blower 9. To facilitate starting the vehicle from cold, the motor 13 runs at full speed and the by-pass 33 is closed by a valve 21 so that the coolant in the heat-exchanger 20 receives heat transferred from the wall of the chamber 23 by the fresh air. Later, the hot air is bypassed through the passage 33 to the outlet 19. For less heat the motor 13 is slowed and the valve 21 set to allow some of the air to be cooled by passage through the exchanger 20. For still less heat the fuel burner is shut off and the coolant in the exchanger 20 is used for heating the air, but for cooling the vehicle, unheated fresh air is passed through the by-pass 33. In a modification, Fig. 2 (not shown), the heatexchanger 20 is replaced by a jacket 28, Fig. 3, on the wall of the inner housing 2 and it is the coolant supply which is bypassed from this jacket by a valve to control the heating, the air being controlled only by the two speeds of the blower 9. When the coolant is by-passed from the jacket 28, the liquid left therein vaporizes and transmits heat to the surrounding. annular, fresh air space. The air space 3 and the coolant 'jacket 28 contain heat transfer fins 33, 34.

Title: Improvements relating to circuits for the synthetic testing of high-voltage electric circuit-breakers
Inventor: ELLIS NORMAN SADLER
IPC: G01R31/333
Filed: 1963-07-23
Abstract: 1,076,695. Testing circuit breakers. REYROLLE & CO. Ltd. Oct. 22, 1964 [July 23, 1963], No. 29229/63. Heading G1U. A synthetic testing circuit for testing a circuit breaker having one or more low value shunt resistors is of the kind comprising a low voltage circuit whereby a fault current at low voltage is supplied to the test circuit breaker so as to create the required arcing conditions prior to current interruption, and a high voltage circuit, including a voltage injection source capacitor and an inductance, whereby a high frequency current pulse is supplied to the test circuit breaker immediately before the current interruption and the required high voltage across the test circuit breaker is applied immediately following current interruption; an auxiliary circuit breaker being connected in series with the test circuit breaker in the low voltage circuit and one or more capacitors being connected across the test circuit breaker to produce the required transient voltage conditions immediately after current interruption. According to the invention, when such a synthetic testing circuit is used to test a circuit breaker with one or more low value shunt resistors, the or each resistor is disconnected from across the test circuit breaker and is connected, wholly or in part, in parallel with the inductance in the high frequency high voltage injection circuit. In a parallel test circuit (Fig. 3) wherein the high current from a source nE and high frequency high voltage from capacitor Cs are applied to the test breaker T in parallel, the whole of the shunt resistor or resistors is connected across the inductance L in the voltage circuit. In a series test circuit Fig. 6 (not shown) wherein the high current from a source nE and high voltage from a capacitor Cs are applied in series to the test breaker T, only a proportion (1-n)R of the shunt resistor or resistors is connected across the inductance in the high voltage circuit. The remainder, nR, is connected in parallel with a capacitor Cr, which influences the transient voltage conditions after current interruption.

Filed: 1955-10-14
Abstract: 817,278. Electric selective signalling systems. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE SOC. ANON. STIN. Oct. 14, 1955, No. 29284/55. Class 40 (1). In a relay chain control system, ganged control switches S1, S2 having a rest position O and operative positions X, Y excite a relay 1 (which may be a polarized 3-position relay or a combination of several realys) to place contacts 1a, 1b in corresponding positions X, Y to energize one of the polarized 2-position relays 2A, 2B, 2C, selected by contacts q1, rl, s1 operated e.g. by a step-by-step switch (not shown) to take up the position X or Y, at which a selected circuit is closed to a positive voltage source by operation in the appropriate direction of the contacts 2a, 2b or 2c selected by contacts q2, r2 or s2 operated e.g. by the step-by-step switch. Operation of relay 1 in the X position also closes contact 1dX and opens contact 1cX, so that for correct switching, the double-wound relay 3, whose windings are connected respectively over contacts 2aX or 2aY and contact q2 to positive battery and over contacts 1fY or 1dX to resistance R and negative battery while also being capable of short-circuiting over contacts 1cX or 1eY, is energized over its m winding and operates contact 3a, which produces an indication of correct operation. Similarly for operation of relay 1 in the Y position, contact 1fY is closed. and 1eY is opened so that again relay 3 is energized over its n winding to produce an indication of correct operation. Failure of response of relay 2A to the X or Y position of relay 1 prevents operation of relay 3 by closure of contacts X1d or Y1f, while disconnection of relay 2A contacts from both the X and the Y contacts disables relay 3 altogether. Closure of both X and Y contacts of relay 2A by a defect without operation of relay 1 leaves contacts Xld, Y1f open and X1c, Y1e closed so that relay 3 is again inoperative. Failure of control 1cX (or 1eY) to open on energization of relay 1 in the X (or Y) direction leaves both relay coils shortcircuited, while failure of contact 1cX (or 1eY) to close on energization of relay 1 in the Y (or X) direction leaves both windings energized in opposition so that the relay remains inoperative. and no indication is produced.

Title: Improvements in or relating to the removal of water from organic liquids by distillation
IPC: B01D1/16
Filed: 1952-11-21
Abstract: <PICT:0743253/III/1> Organic liquids containing low proportions (less than 5 per cent) of dissolved water are dried by spraying the liquid preferably at a temperature of 50 DEG  to 120 DEG F., into a chamber maintained at reduced pressure such that the water together with a small proportion of the organic liquid are vaporized; the vapours and the residual liquid, i.e. the dehydrated product, are withdrawn separately from the chamber, the vapours are condensed whereupon a condensate is obtained comprising a water layer and an organic liquid layer, and at least part of the organic liquid layer is returned to the low pressure chamber or to the feed thereto. Organic liquids which are dried by the process are those in which water has a low solubility, i.e. not greater than about 5 grm./100 ml.  The following are specified:-Hydrocarbons containing 5 to 13 carbon atoms per molecule, ethyl silicate, amyl acetate, dibutyl ether, ethyl phenyl ether, 2-ethyl hexanol and the corresponding aldehyde, p-ethyl phenol, dipropyl ketone, nonanoic acid, butyl chloride, chlorobenzene, and carbon disulphide.  The liquid to be dried is pumped through line 41 to nozzles 44; and a fine spray of liquid is discharged into the upper section of chamber 43, which is maintained at reduced pressure by ejectors 47 and 55.  The falling spray passes through packing 63, and the water and a small proportion of the liquid are vaporized.  The dehydrated liquid is withdrawn from the bottom of the chamber by pump 45.  The vapours are partially condensed in condenser 49; and the condensate is collected in receiver 51, where decantation of a water layer from organic liquid takes place.  The water is withdrawn through line 52; and the organic liquid is recycled to the feed-line via line 53.  The uncondensed vapours are withdrawn from receiver 51 by ejector 55, and condensed in condenser 57.  The condensate is collected in receiver 59.  Water is withdraw through line 60; and organic liquid is passed via line 62 to the lower section of chamber 43.  This liquid is vaporized in the chamber, and the ascending vapours contact countercurrently the descending liquid spray.  Specification 636,324 is referred to.

Abstract: 1441456 Heating and cooling buildings N LAING 21 June 1973 [23 June 1972] 29514/73 Heading F4U A hollow panel for use in cooling or heating a building comprises a latent heat storage mass 10 spaced from a layer 4, the external surface of which is to be exposed to solar radiation. The layer 4 is capable of emitting infra-red radiation. and a reflecting visible radiation for cooling purposes, or is capable of absorbing visible radiation and of emitting little or no infra-red radiation for heating purposes. In the embodiment shown, a roof panel for use in cooling a building, comprises a latent heat storage mass 10 with a temperature of crystallization of 17 C. a zone Z filed with a fluid heat carrier and an outwardly facing wall 4. When the ambient temperature is above 17 C., the roof panel acts as a thermal insulator, the layer 4 reflecting visible radiation. The latent heat storage mass 10 absorbs heat from the room to keep the temperature of the room below 17 C. When, usually at night, the ambient temperature drops below 17 C., there is transfer of heat by the fluid heat carrier from mass 10 to the layer 4, which is thereby kept at a substantially constant temperature, and emits the heat as infra-red radiation. In other embodiments, a honeycomb support structure (11, Fig. 5a) may be present within the panel along with drop points (8, Fig. 5a); or the panel may be open, heat being transferred by air between the layer 4 and a storage mass container of cruciform rib construction (10, Fig. 6). In a roof panel for use in heating a room, the latent heat storage mass absorbs latent heat at a temperature above the desired room temperature. When conditions are such that the ambient temperature is below the operating temperature of the latent heat storage mass, no heat is lost through the layer 4 in the form of infra red radiation. When the ambient temperature is above the operating temperature of the storage mass, there is transfer of heat from the layer 4 to the latent heat storage mass by means of the fluid heat carrier, the layer 4 thereby being maintained at a substantially constant temperature. In this case (Fig. 4a, not shown), the condensate of the heat carrier collects in troughs and is returned to the layer 4 by strips of capillary material. An inflatable bellows (36, Fig. 4a) is provided to control the amount of condensate present in the troughs. A list of materials and coatings for the layer 4 is provided, along with a list of fluid heat carriers.
