Title: Improvements relating to the air cooling of heat exchange surfaces in moving vehicles
IPC: F01P7/10
Filed: 1945-08-22
Abstract: 597,200. Automatic control systems for aero-engine cooling devices. JENNINGS, H. W. K. (Sturtevant Co., B. F.). Aug. 22, 1945, No. 21492. [Class 38 (iv)] [Also in Group XXVII] In an aero-engine air cooling system, means are provided for varying the volume of air moved over the cooling surface and for relating the velocity of the cooling air discharged from an aircraft to the aircraft speed. As shown, the electric motor 25 and gears 22 control the positioning of vanes 26 situated in the entrance of the engine cooling, and motor 50, by means of connecting rod 64 and screw-shaft 62, the setting of flaps 51 at the exit louvres. Power for both motors is supplied by battery 36. Changes in engine temperature cause mechanical movements in the thermostat 27 which operate the arm 24 carrying mutually insulated switch members 28, 59, which, when the engine is overheated are in the right-hand position and meet contacts 29, 104 and 58, 84, closing circuits through relay 34 which connect the field winding of motor 25 to the armature to rotate the vanes 26 to the open position. With the engine overcooled, arm 24 moves leftwards and switch member 28 forms a circuit with contacts 42, 106 which causes relay 34 to connect the field of motor 25 to the armature in the reverse direction to rotate the vanes to the closed position. Impact tubes 52, 53 exposed to the airstream (or slipstream) and to the air in the exit louvres respectively, are connected to the chamber 66 to cause diaphragm 67, and its associated contact arm 68, to move in response to a difference of air velocities between 52, 53. With the vanes 26 under control of thermostat 27, the diaphragm 67 moves contact arm 68 to operate relay 76 which connects the field and armature of motor 50 to cause the motor to adjust the flaps to maintain the difference in velocity at the two impact tubes at zero. With the vanes fully open and the thermostat still registering an, excessive engine temperature, the motor 25 continues to rotate until the cam 41 moves the switch members 32, 60 to the left (i.e. the position shown) causing the energization of solenoid 55, from battery 36, and thereby causing armature 91, 74 to meet contacts 97, 99. Control of motor 50, through relay 27 adjusts the flap opening to raise the rate of passage of air through the exit cowl. Conversely, if the engine becomes too cool the thermostat reduces the flap opening. Control of the vanes and flaps is restored to the thermostat and diaphragm respectively when the thermostat arm 24 returns to its neutral position. Orthodox limit switches are fitted to both motors 25 and 50. In a modification, Fig. 4 (not shown), the air from impact tubes 52, 53 acts on separate, dissimilar, interconnected diaphragms to allow for the expansion, due to heating, of the cooling air. Specification 358,154, [Group XXVI], is referred to.

Title: Improvements in or relating to cooling systems for gas filled electron discharge devices
Inventor: COLLAR CHARLES GEORGE
IPC: H01J13/32
Filed: 1954-07-27
Abstract: 774,412. Cooling discharge tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 9, 1955 [July 27, 1954], No. 21862/54. Class 39(1). The cooling of a grid-controlled gas-filled discharge device, such as a thyratron, or a mercury-cathode tube, is controlled by means dependent upon the duration of flow of the grid current. This duration increases with increase of temperature. Fig. 1 shows a circuit incorporating a mercury-cathode tube 1 comprising two anodes and grids and a triggering electrode 3. A pulse generator applies similar pulses to grids 4 and 5, those to grid 4 being slightly in advance. The two halves of the tube switch on in turn, an output pulse of length dependent on the constant of the delay line being produced at terminals 18. The grid current operates a relay 21, 22 which controls the blower motor 23. The cooling is thus dependent on the mean grid current, and can be adjusted to operate when this reaches a value corresponding to the upper permissible temperature limit. Either grid 4 or 5 can be used as the control, the latter being preferred. Fig 2 (not shown) is an elaborated arrangement to give improved sensitivity. The relay controlling the blower motor is no longer directly in the circuit of grid 5, but is operated by a valve, normally conducting ; this is cut off, operating the relay, when its negative grid bias, deriving from the pulses from grid 5 and varying therewith, reaches a sufficient value. This valve is replaced in Fig. 3 (not shown) by a double triode in an arrangement to give sharper on-off control of the blower motor. In the arrangement of Fig. 4 (not shown), positive pulses of grid current from grid 5 are compared with synchronously produced negative pulses of predetermined length, these being applied respectively to the first and third grids of a pentode. When the positive pulses become longer than the negative pulses, the pentode becomes conducting, and can be utilized to control the blower in any of the ways previously described.

IPC: A63H15/02
Filed: 1919-09-12
Abstract: 154,010. Slade, A. Sept. 12, 1919. Mechanical toys.- A mechanical toy, in which a driving-pulley, adapted to travel along an inclined cord, is provided with cranks by which parts of the toy are moved, has a counterweight suspended directly from the axle of the pulley and one or more links, forming no part of any movable member of the toy, connecting the cranks with the movable member. In the construction shown in Fig. 3, the counterweight D<2> is suspended by wires D<1> from the axle of the pulley A which runs on a cord B. The body H of the toy is formed of two thicknesses of sheet material secured to an extension D of the wires D<1> and arranged in either side of the pulley, so that the latter is partly concealed. Links G<1> connect cranks C, formed on the axle of the pulley, to the limbs H<2> of the figure so that as the toy moves, the animal appears to be running along the cord. The body may represent a butterfly, the links being connected to the wing. In a modification, the body may be suspended below the cord the counterweight being dispensed with. As shown in Fig. 4, a figure representing an acrobat is suspended by the arms J from the axle of the pulley, and the links G<3> are connected to a crank K<1> formed in the wire by which the body is pivoted to the arms. Thus as the toy runs along the cord the body swings and the legs which are pivoted to the trunk also swing. To steady the toy and to prevent the pulley from leaving the cord, a cross arm J<1> attached to the arms J is provided with eyelets J<2> through which the cord is passed. Alternatively, the toy may be provided with guide pulleys A<1>, Fig. 5, disposed above the pulley A in either side of and in line therewith, the cord B being led over the driving pulley and under the guide pulleys. According to the Provisional Specification, the toy may be operated by holding an end of the cord in each hand and moving the hands up and down oppositely and alternatively. Thus a toy representing a butterfly, say, is made to appear to hover.
