Title: Focused electromechanical transducing device
IPC: H04R17/00
Filed: 1950-03-06
Abstract: <PICT:0684418/IV (a)/1> Thermo-setting material carried in moulds 91 is subjected to heat treatment by ultrasonic acoustic energy which is radiated by a cylindrical trough 81 of a polycrystalline dielectric transducing material (see Group XXXIX) and concentrated in the longitudinal axis, the moulds being wholly or partially immersed in a suitable acoustic conducting liquid 86 and moved along the axis by a conveyer 88.ALSO:<PICT:0684418/III/1> <PICT:0684418/III/2> Chemical reactions in a fluid may be accelerated by the application of ultrasonic acoustic energy which is concentrated at the common centre of curvative 41 of two polycrystalline dielectric transducers 44, 45 formed with concave spherical or cylindrical surfaces (see Group XXXIX).  In an arrangement for degassing a liquid 109, Fig. 6, contained in an open-topped tube 108 provided with an exit pipe 111, the ultrasonic energy radiated by a transducer 101 to its centre of curvature is delimited by an acoustic lens comprising a shaped aluminium plate 107 which closes the lower end of tube 108.  This arrangement avoids the violent reaction which may occur due to concentrated acoustic energy. In an alternative embodiment, Fig. 7 (not shown), the radiated energy is transmitted into the tube by an acoustic reflector.ALSO:The ageing of spirituous beverages is accelerated by the application of ultrasonic acoustic energy concentrated at the centre of curvature of a polycrystalline dielectric transducer having a concave spherical radiating surface (see Group XXXIX).

Title: Improvements in or relating to fluid heaters and a method of heating a fluid
IPC: F01N5/00
Filed: 1952-03-04
Abstract: 725,140. Systems for heating fluids. THOMPSON PRODUCTS, Inc. March 4, 1952 [July 13, 1951 No. 5627/52. Classes 64 (1), 64 (2) and 64 (3). [Also in Groups XXXIV and XXXVI]. A fluid heater which may be used for heating water for army camps &c. and for thawing out frozen engines or maintaining engines at a suitable temperature for starting, comprises a heat engine, a hydrodynamic brake driven by said engine, a heatexchanger, a brake fluid circuit for said hydrodynamic brake including a conduit circulating the brake fluid through the heat exchanger and back to the brake, and means for circulating fluid to be heated (e.g. water) in heat exchange relation with both the heated fluid in said brake fluid circuit and with heat liberated from said heat engine. In the form shown an internal combustion engine 12 drives a pump 26 for the circulation of engine coolant (e.g. water), an electric generator set 13, a pump 14 for the circulation of fluid to be heated and a fluid friction brake 15 of the self circulating type the operation of which is controlled by a handle 47. Fluid to be heated is delivered by the pump 14 through a conduit 33 to a heat-exchanger 21 where it absorbs heat from the engine coolant delivered thereto through a conduit 27 and from the brake fluid which circulates through the heat exchanger by way of conduits 54, 58. The elements of the heat exchanger comprise concentric tubes 30, 35, 56 forming passages A, B, C, (Fig. 3) through which the respective fluids pass, the fluid to be heated flowing through the passages B between the passages A and C through which flow respectively the hot engine coolant and the hot brake fluid. After being heated in the heat exchanger 31 the fluid receives further heat at 38 from the engine exhaust gases before being passed to the point of use. In an alternative arrangement (Fig. 2A not shown), the separate coolant circuit for the engine is omitted and the fluid to be heated is passed by the pump 14 to the engine as coolant and thereafter flows through a heat exchanger where it is heated by the brake fluid and thence through a conduit in the engine exhaust pipe where it receives further heat from the exhaust gases and thence to the delivery point. Alternatively the liquid from the pump 14 may be first heated by the brake fluid and then by the engine. The heated fluid may be circulated through another engine or a number of other engines and through a jacket surrounding the battery (Fig. 5 not shown) to enable these engines to be maintained at a temperature such that they may be started easily when exposed to arctic temperatures.

[Also in Division F1] In a fluid-pressure motor, in which a piston 14 slides on a rod 16 extending through an end of the cylinder 10 and thrust is transmitted from the piston to an abutment 21 through a spring 19, a predetermined movement of the piston under fluid pressure closes a leakage path 17, 18 between opposite sides of the piston. With no fluid pressure piston 14 takes up a predetermined position under the action of spring 22. The movement of the piston compresses both springs 19, 22 and applies a gradually increasing thrust to the piston-rod 16 through spring 19 until bore 18 is closed, when the full available thrust is exerted. The abutment 21 may engage the cylinder 10 to limit the return movement. The fluid pressure, e.g. air pressure or liquid pressure, may apply a brake 26 to a drum 27 in an automatic transmission mechanism or may be used to close doors or windows. Specification 1,101,941 is referred to.

Patent GB-658308-A (GB)
Title: Improvements in or relating to electronic valve circuits
Inventor: WELLS FRANK HERBERT
IPC: H03B19/12
Filed: 1949-03-03
Abstract: 658,308. Pulse generating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 3, 1949, No. 5830. [Class 40 (vi)] The voltage across an impedance is changed progressively in steps by connecting the impedance as the common load for a number of grid controlled valves which have graded grid bias so that the valves are rendered conducting sequentially in response to a progressively changing control voltage. Fig. 1 shows a circuit in which the voltage across a capacitor C1 is initially 60 volts and which is progressively reduced in steps of 12 volts by means of the circuit shown in Fig. 2. Initially valves V2- V5 (Fig. 1) are non-conducting and capacitor C1 is charged to 60 volts. When the voltage across the capacitor is reduced to 48 volts the voltages across resistors R1 fall proportionally and valve V2 conducts and diode V2A is rendered non-conducting. The anode voltage of valve V2 thus falls to that of the grid, i.e. 48 volts and the voltage on capacitor C1 is stabilized at this level until the next input pulse appears when the charge is reduced to 36 volts. Valve V3 and diode V3A then conduct and the voltage of capacitor C1 is stabilized at the new voltage. Valves V2- V5 are thus rendered conducting in succession until the voltage across capacitor C1 is restored to 60 volts when the circuit reverts to normal. Fig. 2 shows a circuit for discharging capacitor C1 in steps. Initially the capacitor is charged to 60 volts and a positive going input pulse applied to valve V causes a large current to flow in this valve so that the anode potential and thus the voltage on capacitor C2 drops, diode D2 conducts and the charge on capacitor C1 is thus reduced, the values of capacitors C1, C2 being such that a voltage reduction of 12 volts is produced across capacitor C1. At the end of the input pulse valve V reverts to its normal non-conductive condition diode D1 passes current to recharge capacitor C2, and as diode D2 is non-conductive the reduced voltage across capacitor C1 remains unchanged. Successive input pulses thus reduce the voltage across capacitor C1 in steps of some 12 volts, until when the voltage across the capacitor falls below 12 volts the voltage across resistor R1 falls to its lowest value and the cathode of valve V6 is driven negative. Valve V6 thus executes an oscillation and is " blocked," a positive pulse is produced at its grid which is limited to 60 volts by a biased diode D4, the cathode voltage of valve V6 thus rises to 60 volts and capacitor C1 is recharged to 60 volts via diode D3. As the blocking oscillator stage V6 is triggered when the voltage across capacitor C1 is reduced to a predetermined value, i.e. when a predetermined number of input pulses have been applied, the circuit may function as a counter or frequency divider.

Title: Improvements in and relating to liquid fuel burners
IPC: F23C7/00
Filed: 1926-03-02
Abstract: 265,402. Baulino, C. March 2, 1926. Spray burners.-An atomizer shown in Fig. 2 for use in a liquid fuel furnace comprises a cylindrical casing A formed at one end with a conical seating B terminating in a divergent orifice C. A conical head D abutting against the seating B is formed with a number of channels E which are inclined to the generators of the conical surface and are of diminishing cross-section. The head D is carried by a rod K which is subjected to the pressure of a spring S arranged in a cap screwing in the other end of the casing A. The liquid fuel is supplied through a valve V and passes through a filter R carried by enlargements on the rod K. The fuel receives a helical movement by its passage through the channels E and issues into the furnace through the orifice C. The orifice C is made of larger cross-section than the total cross-section of the channels E so that the liquid fuel does not entirely fill the orifice and is discharged in a hollow conical jet. Fig. 4 shows the fuel atomizer R arranged to discharge into a furnace the initial portion of the jet being protected by a cone G substantially parallel to the jet and additional air being injected by the stokehold fans through an annular duct B so as to impinge normally on the jet. The walls C, D of the duct may be fitted with adjustment handles F, E and the atomizer R may be adjustably mounted in respect to the cone G.
