Abstract: 176,335. Dehle & Sewerin. Feb. 26, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Spray carburettors.-The nozzle c projects from the casing b into a rotary throttle valve d which is cut away at q and is provided with conduits n, o. During slow-running, mixture is delivered by the conduits n, o only but, as the throttle is opened, the cut-away passage q is brought more and more into action until, at full throttle open. ings, the passage q is practically transverse to the nozzle and the conduit n is cut off. The passage n may be obstructed by an adjustable bolt p, and the passage around the nozzle at half and full throttle openings may be regulated by a spring blade s adjusted by a screw t. The fuel flows from the float chamber a through a re stricted orifice in an interchangeable plug to a conduit h, to which air is admitted through orifices m and a conduit l controlled by a valve k. A sleeve v surrounding the nozzle c and communicating with the bore thereof through ports x acts as a nozzle under high loads and when the nozzle c is obstructed. The throttle valve is ad justably mounted on its spindle.

Title: Improvements in variable voltage transformer arrangements
IPC: B60L9/26
Filed: 1955-01-28
Abstract: 776,197. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 28, 1955 [Jan. 28, 1954], No. 2698/55. Class 38 (2). [Also in Group XXXVII] A load such as a traction motor connected between centre tap 4 of a secondary winding 3 of a main transformer 1 and junction 28 of the cathodes of mercury arc rectifiers 25, 25 is energized from windings 2, 2<SP>1</SP> of transformer 1, with voltage varied by altering the value of series opposing or aiding voltages from tapped winding 3 by means of an on-load tap changing arrangement. For maximum buck, main contactor 11 and auxiliary contactors 30, 31 are closed. The bucking voltage comprises that between taps 4, 5 of winding 3 added to that developed in the lower half of secondary winding 16 of auxiliary transformer 17 from the primary winding 29 connected through reversing switch 41 and reactor 38 across taps 6, 6<SP>1</SP> of winding 3. To increase the output voltage, the voltage of the lower half of the winding 16 is reduced to zero in steps by opening and closing auxiliary contactors 30-35 in sequence, until contactors 34, 35 are closed, the operating reversing switch 41 and reversing the operation of the contactors 30, 35 until with reclosure of contactors 30, 31 the voltage in the lower half of winding 14 has been completely reversed. The voltage across winding 16 is now of such magnitude and direction that its upper end 14 is at the same potential as tapping 7 so that contactors 10, 11 can be closed and opened respectively. By repetition of this sequence, the backing voltage may be derived in turn from each tapping of winding 3 until it is zero at tapping 4 when contactors 8, 34, 35 are closed. By operating reversing switch 20 and carrying out the tap changing in reverse, a boost voltage may be added to the output voltage of winding 2 in steps of increasing value until the maximum value of boost equals the value of the original bucking voltage. The right-hand half of the circuit is operated simultaneously with the left-hand half, but may be omitted together with the rectifiers if A.C. motors are being supplied. For rheostatic braking the motor field windings may be connected in series, seriesparallel or parallel between terminals 4, 28 and, if desired, by operating two-way switches 43, 43<SP>1</SP> to close contacts 45, 46, 45<SP>1</SP>, 461, windings 2, 21 may be cut out. In a modification, Fig. 3 (not shown), windings 2, 2<SP>1</SP> and change-over switch 20 are omitted and to each tapping on winding 3 are connected two contactors connected to separate secondary windings of transformer 17 so that two loads can be supplied and controlled together in parallel. So that the value of the voltage steps may be increased as the voltage increases whereby constant tractive effort steps are maintained with reduction of' the number of contact steps, tappings may be spaced unequally on winding 3, and on the secondary windings of transformer 17, Fig. 5 (not shown).

IPC: H05B3/16
Filed: 1970-01-21
Abstract: 1281861 Electric heating TRONAPPLICS Ltd 21 Jan 1970 3001/70 Addition to 1270250 Heading H5H [Also in Division G3] In an arrangement as described in the parent Specification in which a heating apparatus comprises at least two elements fed with pulses of opposite polarity and alternating in time, the elements are of elongated form wound with resistive wire of diameter 0À015 inch diameter or less, or non-circular conductors of equivalent cross-sectional area, and preferably 0À0076 inch or less or equivalent. Each element may comprise a number of conductors in parallel. Where used for liquid heating, elements may be embedded in refractory, fibrous mineral, or particulate mineral material. Where for air heating elements may be disposed in a duct with a fan passing air downwardly at a rate to prevent the elements glowing red, and with a thermal cut-out to sense hot air rising if the fan fails. A heating element may comprise a plurality of conductors arranged in open helical coils supported by rods 24 of heat insulating material carrying perforated spaced discs 26, the rods being held by nuts 36 to board 34. Terminals 30, 32 &c. are provided and may be connected by conductors of printed circuit type. It is considered that the downstream surface of small diameter conductors dissipate heat more effectively because there may be less tendency for air flowing to break away; if there is break away then the close proximity of down and up stream sides will permit sufficient conduction of heat from one to the other surface.

Title: Hydraulic apparatus
Inventor: STERN THOMAS ARTHUR WILLIAM
IPC: F15B11/00
Filed: 1961-01-26
Abstract: 921,843. Hydraulic apparatus. ROLLSROYCE Ltd. Jan. 19, 1962 [Jan. 26, 1961], No. 3045/61. Class 69 (2). Hydraulic apparatus comprises a chamber 20, Fig. 1, a common inlet and outlet duet 18 with a shut-off valve 17 therein movable between open and closed positions or separate inlet and outlet ducts each of which has a shut-off valve, means 12 for pumping hydraulic liquid through the inlet duct towards the chamber, and a restricted path 19 by-passing the or each shutoff valve to allow restricted flows of hydraulic liquid past the shut-off valve or valves. The flow through the restriction 22 in the path 19 compensates for any leakage which may occur from the chamber so that when a piston 21 is moved to an end position against the force of a spring 23, it is retained there by the flow through the restriction when the valve 17 is closed. The piston has a rod 23 which may be connected to the forward nose portion of the air intake disclosed in Specification 883,634. The pump receives liquid from a reservoir 20 and delivers it through a duct 13 to an accumulator 15 joined by a duct 16 to the shut-off valve 17 and the path 19. A second shut-off valve 17a is disposed between the duct 16 and the reservoir 10. When both valves 17, 17a are opened, the piston moves to the left and can be maintained in its new position by closing valve 17. Opening of valve 17 and closing of valve 17a permits liquid from the pump to move the piston to the right against the spring when it can be retained by closing both valves. In another embodiment, supply and exhaust ducts 40, 43, Fig. 2, are connected to a shut-off valve 62 which is connected to an inlet duct 56 leading to one end of a cylinder 50 joined by ducts 54 to a series of cylinders 51, 52, 53, cylinder 53 being connected by an outlet duct 60 to the valve 62. Passages 65, 67 having restrictions 66, 68 by-pass the valve 62 to connect the inlet and outlet ducts 56, 60 to the supply and exhaust ducts 40, 43, respectively, to compensate for any leakage from the cylinders when the valve 62 is in its closed position. The valve 62 is movable to two other positions to effect up or down movement of pistons in the cylinders. The restrictions may be in the form of labyrinth seals or annular gaps between a housing and a plug fitted therein. Pressureresponsive switches 57, 61 are provided to indicate a loss of pressure, which may be caused by failure of one or other of ducts 56, 60, and to close blocking valves 55 in the ducts 54 whereby the cylinders are isolated and the pistons are locked in their position at the time of failure. The blocking valves are also arranged to be closed when the valve 62 is in its closed position and the pistons are at the upper ends of the cylinders to prevent flow through the restricted paths 65, 67 moving the pistons. Additional ducts 70, 71 having restrictions 72, 73 may be provided to obtain synchronous movement of the pistons with the valves 55 open.

[Also in Group XXXIII] An aircraft comprises an isentropic air intake having an upper wedge with leading edge 9 upstream of the leading edge 10 of a lower wedge and a throat 11 leading to a diffuser passage 19 which diverges laterally, Fig. 2, and also diverges vertically behind a station 40, and leads to a plurality of compartments formed within the fuselage by splitter plates 114, and each containing one or a pair of ram jet engines 155, and a variable two-dimensional nozzle 238. The wedge leading edges 9 and 10 are swept back from the central vertical plane of symmetry. The two side walls of the intake are cut away along swept-back edges 26, 27 which lie along the shock waves generated by the edges 9 and 10 at the design Mach number. The free stream intake area at edge 9 is square. The opposed faces 12, 13 of the wedges diverge from each other, going laterally outwards from the vertical plane of symmetry. This assists in spilling air from the intake through the cutaway parts of the side walls, at speeds below the design Mach number. At such speeds, the lower edge is tilted towards the upper wedge, as shown in broken lines, about a pivot 16, to reduce the free stream intake area, and increase the area of throat 11, a part 22 of the diffuser passage also tilting about pivot 24 so as to continue the upper surface 13 of the wedge.
