Title: Adsorption apparatus and method
IPC: B01D53/04
Filed: 1943-09-07
Abstract: 577,537. Adsorption apparatus. COMMONWEALTH ENGINEERING CO. OF OHIO. Sept. 7, 1943, No. 14666. Convention date, Aug. 7, 1942. [Class 1 (i)] An adsorber comprises a cylindrical vessel containing a plurality of concentrically and longitudinally disposed beds of solid adsorbent material preferably active carbon, and means for successively directing the fluids to be treated through said beds in a transverse direction thereof, the beds diminishing in thickness from the centre toward the periphery of the vessel and being enclosed and spaced from the walls of the vessel by foraminous members. Fig. 1 shows an adsorber adapted for horizontal installation and a further modification (not shown) is described adapted for perpend:cular installation. As shown the beds are provided with an extra space containing excess adsorbent material whereby the formation of low or thin spots in the beds is avoided. Fig. 5 shows a modification of the closure between the concentric beds. An adsorption system for dealcoholising and deodorising fermentation carbon dioxide involving the use of two such adsorbers and a common condenser is described in detail. The apparatus is also applicable to the treatment of other gaseous materials for the purpose of deodorising them and removing entrained vapours therefrom, e.g., to the recovery of valuable vapours and removal of odorous impurities from coke oven gas.

Title: Improvements in time-base circuits
Inventor: OXENHAM JOHN KENNETH
IPC: H03K6/04
Filed: 1958-05-07
Abstract: 858,225. Valve sawtooth generating circuits. SYLVANIA-THORN COLOUR TELEVISION LABORATORIES Ltd. May 7, 1959 [May 7, 1958; Nov. 28, 1958], Nos. 14685/58 and 38522/58. Class 40(6). In a sawtooth current generator of the type in which a driver valve feeds the deflection coils through a transformer across which is connected a damper valve and capacitor in series, a further capacitor is connected in series with the damper valve and a circuit is provided which returns the capacitor voltage to a predetermined value during the flyback so causing the waveform of the capacitor voltage to have a parabolic component. In the Figure, the driver valve 10 feeds the deflection coils 14 through a transformer 11 across which is coupled a damper diode 13 in series with a boost capacitor 12. A further capacitor 17 is connected in series with the damper diode in parallel with a transistor 15 which is rendered conductive during the flyback to discharge the capacitor. The D.C. and sawtooth components of the damping diode current during the forward stroke build up voltages across capacitors 12 and 17 which compensate for non-linearity of the deflection due to the resistance of the coil circuit and the large radius of the cathode-ray tube face. When the voltage across the capacitor 17 is high the capacitor may be replaced by a number of larger capacitors connected in series each being provided with its own discharging transistors (Fig. 5, not shown). In an alternative embodiment (Fig. 6) the transistor is omitted and winding 18 is connected across the capacitor in series with a diode which is rendered conducting during the flyback so as to charge the capacitor 17 to a predetermined value (Fig. 6 not shown).

Title: Improvements relating to the control of electric motors driving pumps and compressors
Filed: 1922-05-25
Abstract: 180,682. Ibach, P. May 25, 1921, [Convention date]. Regulating delivery by varying speed of motor.- In apparatus for controlling electric motors driving pumps and compressors of the kind comprising a piston b exposed to the delivery pressure and adapted to operate the motor switches f, g against the action of counterweights d, e, the armatures of an electromagnet o energized by the working current carries a valve which opens a pipe r to the pressure supply when the current fails and admits pressure fluid to the underside of a piston t which is of larger area. than the weighted piston valve i controlling the admission and exhaust of pressure fluid to and from the piston b by the pipe h. The piston b in rising lifts the piston i by means of a rod u to the same position as if it were lifted by the pressure fluid at its maximum pressure. A locking device v operated by a spring and by a piston w exposed to the pressure fluid locks the switch-operating mechanism in the off position when the pressure of the fluid is low. In another form suitable for liquid pumps, the delivery pressure acts on a perforated piston connected to two valves controlling respectively the inlet and outlet of pressure liquid to and from the piston operating the switch. The cylinder in which the perforated piston works has two outlets, one controlled by a valve operated by an electromagnet, the other by a valve operated by a diaphragm exposed to the delivery pressure. If the current fails or the pressure reaches a maximum, one or other of the outlets is opened and the pressure on the perforated piston is relieved of pressure on one side and is raised by the pressure on the other side to open the inlet valve to the switch-operating piston.

Filed: 1933-05-22
Abstract: 403,290. Master control of A.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Seeger, E. W.; 12th Street, Milwaukee, Wisconsin, U.S.A.) May 22, 1933, No. 14738. Convention date, May 20, 1932. [Class 38 (iii).] A motor 1 is plugged to rest by closure of a reverse contactor R, after a forward contactor F has been opened by opening of a stop pressbutton, the contactor R also being under the control of a relay 25 which during forward operation is mechanically latched by means 27, 28, but which is freed from its latch by closure of the contactor R, and remains under the control of a winding 30 connected in the rotor circuit of the motor, so that when the motor has slowed down or come to rest the relay 25 opens and de-energizes the contactor R to disconnect the motor. When an " inch " button is closed, the forward contactor F and a torque contactor T close, the latter shortcircuiting rotor resistances. The coil 30 closes the relay 25 with certainty and the relay is maintained by the mechanical latch. Upon release of the " inch " button the contactors FT open, and the contactor R closes to plug the motor and release the latch on the relay 25 which opens when the motor slows down or stops to de-energize the relay R and disconnect the motor. When a "Run" button is depressed the contactors F, T, and a relay 24 close, the latter maintaining itself and providing a circuit for the contactor F independently of the contactor T which opens when the "Run" button is released. Release of the " Run button causes a contactor S to close which shortcircuits rotor resistance to give a predetermined running speed, and also short-circuits the coil 30 of the relay 25. When a stop button is opened the relay 24 and contactors F, S, open, the contactor R being closed as a consequence, and plugging being effected under the control of the relay 25 as described in connection with the stopping of the inching operation. The relay 25 may have an additional winding connected in series with the winding 30 by closure of the contactor T to provide increased power for closing the relay, or it may be mechanically closed by closure of the contactor F.

Abstract: 1,217,034. Preparation of furnace carbon black. CONTINENTAL CARBON CO. 27 March, 1968 [21 April, 1967], No. 14742/68. Heading C1A. Furnace carbon black is prepared by introducing a combustion fuel, e.g. CH 4 , and oxygencontaining gas, e.g. air, into a combustion zone burning the mixture to form combustion gases and heat, passing the combustion gases and heat to a reaction zone 14 where a hydrocarbon feedstock and superheated steam in an amount of 0À2 to 2À0 pounds of steam per gallon of hydrocarbon feedstock are contacted with the combustion gas to form carbon black, the carbon black formation is terminated by passing the reaction products into a quenching zone 16 contacting with a quenching medium and removing the quenched reaction products from the reactor. The combustion fuel and oxygen-containing gas may be introduced into the combustion zone as a mixture. The superheated steam and hydrocarbon feedstock may be premixed before introduction into the reaction zone, or the superheated steam may be introduced separately and coaxially about the feedstock.

Patent GB-457118-A (GB)
Title: Improvements in or relating to control mechanism for change speed gearing
Filed: 1935-05-21
Abstract: 457,118. Controlling change speed gearing. ROBOT GEARING, Ltd., 39, New Broad Street, London, and KAMPER, A. M., 182, Ewell Road, Surbiton, Surrey. May 21, 1935, No. 14851. [Class 80 (ii)] A hydraulic or other servo-motor 15 for interrupting the transmission of a vehicle prior to, or during, a speed-change, is actuated by momentarily downwardly pivoting a manual control-lever 18, which can also be turned in its own place to operate a preselector lever 14 without actuating the servo-motor. Speed changes can be effected preselectively or instantaneously at will. At the end of a full stroke, the servo-motor is automatically tripped and returns to its initial position at a rate which may be controlled by the position of the selectorlever 18. The piston 40 of the servo-motor acts directly on a pedal 34 which may be the executive pedal of a preselector gear of the Wilson type or of that described in Specification 445,262, the pedal acting through a spring 37 on an executive control 13. The servo-motor is energized by closing a normally-open doubleseated balanced valve 47 so as to cut-off communication between a pressure-chamber 45 and exhaust ports 52, and cause the pressure to act directly on the piston 40 through a non-return valve 53. With the valve open, the servo-motor exhausts through an adjustable throttling- passage 54 which may also comprise a camactuated plunger controlled by the position of the preselector-lever 18 so as to provide for slower engagement of the drive in first and reverse speeds. Alternatively there is a stop 65 beneath the preselector-lever in first and reverse speeds so as to prevent use of the servomotor and enforce manual operation of the executive pedal 34. The servo-motor valve 47 is operated through a double-armed bell-crank lever 59 between the arms of which the valvestem is pivoted eccentrically of the fixed pivot 60 of the bell-crank lever. A tension-spring 63 connects the free end of the bell-crank lever with the adjustable end of an arm 62, rigid with the executive pedal 34. Depression of the selectorlever 18 acts, through a rod 27, flexible cable 30 and a plunger 64, to tilt the bell-crank lever 59 anticlockwise in Fig. 5, thus moving the centre-line of the spring 63 from the underside to the upperside of the pivot 60 of the bell-crank lever. The spring 63 thereupon raises the valve, thereby closing it and energizing the servo-motor. At the completion of the stroke of the latter, the arm 62 restores the centre of the spring 63 to its former position beneath the pivot 60, thereby reopening the valve and automatically de-energizing the motor. The valve is stabilized in this position independently of manual operation of the pedal 34. The pressure system includes a reservoir 15, pressure-relief valve 44 and an engine-driven pump 16, and is entirely independent of any other pressure system on the vehicle.

Abstract: 1299358 Plates of parallel hollow glass fibres MULLARD Ltd 31 Dec 1969 [24 March 1969] 15212/69 Heading C1M In the manufacture of channel plates of parallel hollow glass fibres for electronic imaging purposes, an array of "pre-tacked" slices are sealed to each other at their edges by transverse compression and heat to form a larger plate, the compression and heat being sufficient to compact and seal together the individual fibres or multifibres of each constituent slice, the supporting cores (e.g. of a different glass) if present, being subsequently removed, e.g. by etching. "Pre-tacked" slices are defined as slices cut from packages of multifibres which have been lightly tacked together by heating without closing the interstices between by compression. Apparatus, for carrying out the method, comprises a base 1 and pressure plate 3 with ridges 5, 8 which clamp the outer edges of an annular foil diaphragm 6 against the base 1 and a sealing platten 9 respectively, the clamping being effected by nuts (4) on studs (2) and nuts(10) on studs (11) through plate 3 to base 1 and platten 9 respectively. The array 7 of pretacked slices are then assembled, the apparatus heated to sealing temperature (e.g. 550-750‹ C.) and the space between plate 3 and diaphragm 6 pressurized by nitrogen through an inlet (12). Vacuum may also be applied in the early stages to the array 7 through a vent (13). The diaphragm 6 may be of aluminium foil or annealed copper and pressure of 600-1000 lbs. per square inch. In place of direct action of the diaphragm 6 on the array 7, a ring of segments 14, e.g. of stainless steel, may be interposed between.
