Title: Improvements in or connected with the heating or the heating and drying of air within structures normally forming closed areas
IPC: F26B21/08
Filed: 1931-01-30
Abstract: 371,933. Drying air. BURNSIDE, G. B., 104, Beechwood Drive, Broomhill, Glasgow. Jan. 30, 1931, No. 2990. [Class 34 (i).] Condensation of water vapour on the walls. of show-cases and the like A is prevented by causing the air to be heated and to circulate with or without drying in a closed circuit C of which the show-case forms part. Apparatus for attachment to the base of a show-case is shown in Fig. 6, in which air from the case passes down through passage G and up over electric or other heating means D through the passage F. The air may be dried in the downtake by means of a cooling circuit H containing a volatile agent, the condensing coil 8 being surrounded by a sleeve of fabric part of which extends into an annular chamber 11 surrounding the heating chamber D. The liquid in the cooling circuit may be cooled by air circulated through openings 5 above the heating means and drawn through an opening over the coils 9. The cooling in the downtake to condense water vapour may be effected by radiation fins and blackened surface. The inner and outer surface of the heating chamber may be polished. Grids may be provided to cover the air passages.

Title: Improvements relating to direct current regulator circuits
Inventor: HOOPER SAMUEL BRIAN DAVID
IPC: H02P7/29
Filed: 1965-01-26
Abstract: 1,086,752. Control of D.C. motors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 21, 1965 [Jan. 26, 1965], No. 3309/65. Heading H2J. [Also in Division G3] In the absence of any one of a number of conditions of a regulating circuit, a trigger 5 does not provide " on " pulses to a controlled rectifier 7 and the supply of current from battery 2 to traction motor 1 is inhibited. The essential requirements include (1) turn-off capacitor 9 is sufficiently charged, (2) there is no back E.M.F. boosting the supply voltage, and (3) the accelerator pedal 4 is in the starting position. The presence of sufficient charge on capacitor 9 is detected by sensing the voltagedrop across rectifier 8 which is associated with transistor 12 for providing one input to gate 10. Under normal operating conditions, the armature voltage is such that transistor 15 conducts to provide a second input to the gate. When the pedal is depressed, transistor 19 conducts to provide the third input to the gate. The output of the gate is connected to trigger 5 so that initiation of the " on " periods is conditional upon all the requirements being fulfilled. A further requirement may be that there should be no excessive circulating current within the motor circuit before the rectifier 7 is triggered. A signal representing the position of pedal 4 is fed to trigger 5 where it is compared with a signal from current sensing device 6, and, in accordance with this comparison, the mark-space ratio of the motor current is controlled.

Abstract: 560,593. Gas turbines. AKT.-GES. FUR TECHNISCHE STUDIEN. March 1, 1943, No. 3324. Convention date, Feb. 27, 1942. [Class 110 (iii)] A gas turbine plant, working with a closed circuit includes a compressor 1, heat-exchanger 3, heater 5 and turbine 7 and is regulated by varying the quantity of air, or gas, in the closed circuit. On decrease in load an arm 31 turns anti-clockwise and a quick regulation is effected by a valve 16 which opens a line 15, 17 providing a byepass to the turbine. A slow regulation is provided by the closing of contacts 27, 28 which bring into operation an electric motor 19<1> which drives a pump 18 and thereby air is extracted from the circuit at a, point of high pressure and pumped into the high-pressure reservoir 13. In the return movement of the arm 31, the motor 19<1> remains in circuit until the contact between 26 and 27 is broken. For increasing load, the valve 12 opens and air from the reservoir 13 passes into the closed circuit. In one modification the air flowing in the byepass 15, 17 is used to drive a turbine which replaces the motor 19'. In another modification, make-up air is pumped into a lowpressure point in the circuit by means of an electric motor and pump the speed of which is determined by a rheostat under the control of an arm subjected to the pressures of the reservoir 13 and the high-pressure in the circuit in opposition.

Filed: 1929-02-04
Abstract: 327,797. Morgan, G. T., and Pratt, D. D. Feb. 4, 1929. Pitch and tar.-Resinous compounds of high molecular weight are separated from the crude basic, carboxylic acid, and neutral fractions of tar or pitch, by treating the individual fractions with petrol, dissolving the residual pitches in an organic solvent such as ether, benzene, or lowtemperature tar spirit, and finally reprecipitating the resins as amorphous solids by means of petroluem. The resins so obtained are called " resinamines," " resinoic acids," or " resinenes " according as they are obtained from the basic, carboxylic acid, or neutral fractions of the tar. Additional quantities of resinenes are obtained from the pitches thrown down (1) when the caustic soda extract of the tar is saturated with salt, or is extracted with an organic solvent, (2) when the tar is extracted with brine and caustic soda, and (3) when the tar is extracted with acid. These crude pitches are dissolved in an organic solvent and the resinenes are reprecipitated by means of petroleum. In any of the processes above, in which the crude pitches are dissolved in organic solvents, a small proportion of solid remains undissolved; this residue is essentially resinous although of a high melting point, and finds application, as also do the resinamines, resinoic acids, and resinenes, in the manufacture of stains, lacquers, and the like, and in the preparation of moulded articles.
