Title: Heating apparatus burning liquid fuel for heating liquid or gaseous media
IPC: F23D11/06
Filed: 1952-10-31
Abstract: 755,930. Liquid fuel burners. EBERSPACHER, W. and EBERSPACHER, H. [trading as EBERSPACHER, J.]. Oct. 31. 1952 [Oct. 31, 1951 ; May 2, 1952 ; May 2, 1952], No. 27515/52. Class 75(1). [Also in Groups XII and XIII] Heating apparatus burning liquid fuel for heating gas or liquid, e.g. an air heating apparatus as illustrated in Fig. 1, comprises a hollow fuel atomizing device, e.g. a cone 3, rotatably mounted in a combustion chamber 6 disposed coaxially with an annular heat exchanger 10, 16, a combustion air blower 2, a fuel pump 5, and a fuel feed pipe 4 passing into the atomizer 3 and having a section extending transversely to the direction of combustion air flow around the latter. At least one cover plate 17, Fig. 8, may be mounted on the fuel feed pipe 4 to prevent deposition of soot in the cone 3, and also to conduct heat to the fuel passing through the pipe 4. The end 35 of the pipe 4 may be widened conically and extend into the cone 3 at an acute angle to the axis of the latter. The air to be heated is drawn through a noise reducing inlet 12 by a blower 11 and is passed around the heat exchanger, which comprises a cylinder 10 receiving the combustion gases and communicating through transfer ports with a surrounding annulus 16. Air is also fed from the blower 11 through a pipe 30 and injector 31 to the combustion air blower 2. Air may alternatively be supplied by the blower 11 to the blower 2 through an electromagnetically operated valve. The blower 2 is driven by an electric motor 1 which also drives the fuel pump 5 through an electromagnetic coupling 8. The latter is disconnected on closing down the apparatus and the blowers 2, 11 continue to run until the apparatus has cooled sufficiently to actuate a thermal switch 9 to de-energize the motors driving the blowers 2, 11. To ensure intimate mixing of the fuel and combustion air in the chamber 6 the wall of the latter may be formed with annular projections 21, Fig. 3, the diameters of which increase in the direction of air flow. Air guide plates 23 and a star-shaped whirler body 22 are provided in the inlet and outlet, respectively, of the combustion chamber 6. In three further construc! tions the air is directed by annular baffles mounted around the inner wall of the combustion chamber. Alternatively, the chamber 6 may have a conical lining 28, Fig. 6, having a tapered air inlet nozzle 25, and an annular baffle 26 at its outlet end.

Title: Servo Loop Web Tension Control System
Inventor: DIVETO HILLIARD ROY
IPC: G11B15/43
Filed: 1968-06-10
Abstract: 1,195,316. Control of D.C. motors. BURROUGHS CORP. 10 June, 1968, No. 27555/68. Heading H2J. [Also in Division G3] The tape 20 of a magnetic tape unit 10 is automatically maintained at a desired tension by intermittent energization of the D.C. motors driving the reels 14, 16 in accordance with the deflection from a null position of pivoted spring- loaded arms 40, 74 which maintain loops of tape between the reels and the capstan drive 24, 26 and braking unit 34, 36. One of the motors and the control circuit therefor is shown in Fig. 2, the motor comprising split field windings 114, 116 which respectively receive variable and fixed energizing voltages and an armature 156 which may be short-circuited by a transistor 146. The condition of this transistor and the energizing volts applied to winding 114 are respectively determined by the settings of potentiometers 62, 64 whose taps are controlled by a pivoted arm 40 or 74, the arrangement being such that when the arm is in its null position corresponding to the desired tape tension, the net field flux is zero and the armature is shorted out. Movement of the arm from the null position changes transistor 146 to its "off" condition and produces a net field flux which makes the motor rotate in a direction to restore the arm, the motor speed and torque being dependent on the extent of arm deflection from the null position. By using variable and fixed bias on the windings 114, 116 the response time of the control loop is improved compared to a system wherein energizing voltage is switched from one winding to another. The circuit portion 62- 146 provides a damping control for the motor to prevent hunting about the null position.

Abstract: 958,050. Change-speed gear; controlling clutches. FORD MOTOR CO. Ltd. May 31, 1962 [Aug. 4, 1961], No. 28463/61. Headings F2D and F2L. A change-speed transmission for tractors &c. comprises a change-speed gear 3, having its ratios established by liquid pressure servos controlled by a handactuated selector valve 21, in series with a change speed and reverse gear 6 having its ratios established mechanically by actuation of a shift lever 16, an over-ride valve 18 (or 32) being provided to disestablish the ratios in the gear 3 at any time whatever the position of the selector valve 21. Thus a ratio shift, e.g. between forward and reverse, can be effected in the change-speed gear 6 without manual disengagement and engagement of a main clutch 1 through which the change-speed gear 3 is driven. In the form shown, the over-ride valve 18 is mounted in a pipe 19, 20 between a pump 17 and the selector valve 21, and is actuated to vent the selector valve &c. to sump when a projecting knob 16c in the shift lever 16 is grasped, a Bowden cable 16b connecting the knob and the over-ride valve. The changespeed gear 3 may be of the planetary type described in Specification 949,075 in which the various ratios are established by successively supplying liquid under pressure to the ratio establishing clutches, actuating the over-ride valve 18 disengaging all these clutches. Alternatively, if the gear 3 is of the type in which some of the ratios are established by supplying liquid under pressure to the appropriate clutches and some of the ratios are disestablished by supplying liquid under pressure to other clutches, a modified over-ride valve (Fig. 2, not shown) may be located instead at 32, between the change-speed gear 3 and the selector valve 21. As a modification, the over-ride valve 18 can be actuated from an independent pedal. Specification 954,008 also is referred to.

Abstract: 1,158,371. Fluid-pressure servomotor systems. TRANE CO. June 21, 1967 [June 28, 1966], No.28679/67. Heading G3P. A twin-cylinder refrigerant compressor is provided with an unloading valve 68 controlling a by-pass passage inter-connecting the discharge chamber 62 of one of the cylinders to a common suction chamber 50, the valve having an actuating piston 76 continuously subjected on one side 80 to compressor discharge pressure and on the other side 78 alternatively to suction pressure or discharge pressure, dependent on the position of a solenoid valve 88. The solenoid valve 88 is actuated in response to the pressure in an evaporator upstream of the compressor. When the pressure falls below a predetermined value the solenoid coil 98 is de-energized whereby a spring 99 causes a valve member 96 to connect the piston side 78 to discharge pressure via passages 94, 90, 86 instead of to suction pressure through passages 92, 94. The pressures acting on the piston 76 are thus balanced, and pressure in the chamber 62 opens the unloader valve 68. Embodiments are described in which a two-way solenoid valve is used instead of the three-way valve described.
