Title: Altimeter
IPC: G01L9/00
Filed: 1948-05-05
Abstract: 649,952. Altimeters. SQUARE D CO. May 5, 1948, No. 12334. Convention date, May 6, 1947. [Class 40 (i)] [Also in Group XIX] A follow up control system described in Specification 620,279 is modified by a hunting motor 38 driving a cam-shaped contact 22 co-operating with a contact 14 operated by the altimeter bellows, to provide linear operation of the instrument pointer. The motor 38 is provided with two windings 71, 72, both fed from the main aircraft circuit through condensers 73, 74, a valve 75 being connected across the condenser 74. The valve 75 has its cathode 76 and suppressor grid 77 connected to one side of the line and its plate 78 connected through a resistor 79 to the winding 72. The control grid 81 is connected through a limiting resistor 82 to the contact finger 14 and the cam contact 22 is connected to the same side of the line as the cathode. Negative bias is supplied to the control grid 81 through a resistor 83 from the secondary of a transformer 84. The condenser 74 has a lower capacity than the condenser 73 so that when the valve 75 is not conducting the current in the winding 72 will be leading the current in the winding 71 to cause rotation of the motor in one direction. This is the condition when the circuit is broken at contacts 14, 22, when the circuit is completed at these contacts the direction of the motor is reversed.

Filed: 1917-08-28
Abstract: 128,660. Perkin, F. M., and Nitrogen Products & Carbide Co. Aug. 28, 1917. Drawings to Specificatoin. Coking processes.-The process of destructive distillation described in Specification 114,937 is modified to yield a greater percentage of aromatic by-products, more especially of benzene, by mixing acetylene with the gas which is passed through the retorts to assist in the carbonization. The acetylene may comprise from 2.5-10 parts to 100 parts of the other component and of the mixture which is passed into the retort, and the gas with which it is mixed may be the gas which is formed in the retorts after this has been stripped of its condensable portion, or producer gas, or other suitable gas.
Patent GB-581174-A (GB)
Title: A process for the synthetic manufacture of hydrocarbon oils
IPC: C07C1/04
Filed: 1942-09-03
Abstract: Hydrocarbon oils are produced by heating purified water gas (including water gas obtained by complete gasification of coal or a gas obtained by decomposing hydrocarbon gases with steam and/or carbon dioxide) which contains CO and H2 in a ratio between 1 : 1.5 and 2 : 1, in the presence of a cobalt, nickel or iron catalyst at 150-250 DEG  C. and atmospheric or increased pressure to give olefinic products and a residual gas which latter is (a) mixed with gaseous or liquid hydrocarbons and treated with CO2 and/or steam at 800-1500 DEG  C., or (b) treated with CO2 and/or steam at 800-1500 DEG  C. and mixed with water gas and/or water gas previously treated with steam at 400-500 DEG  C., or (c) part treated as in (a) and part as in (b), the two parts then being recombined, the resultant gas then being subjected to a second synthesis in the presence of a cobalt, nickel or iron catalyst at 150-250 DEG  C. to yield further olefines and a second residual gas.  This may be treated similarly and the process repeated until the inert gas content renders it useless.  The treatment with CO2 and/or steam may be in the presence of a catalyst and CO2 may be wholly or in part removed from the mixture of residual gas and hydrocarbons in (a) or from the water gas or water gas treated with steam in (b).  In an example, the synthesis gas containing 41 per cent CO and 51 per cent H2 is treated with a cobalt catalyst at 180 DEG  C., the residual gas being mixed with coke oven gas and heated with steam at 1000 DEG  C. in presence of a nickel catalyst to produce a gas for the second synthesis stage.  The residual gas after removal of CO2 is further treated until five synthesis stages have been effected. The initial synthesis gas may be made partly from coke and partly by decomposition of coke oven gas with CO2.  An example is also given in which the synthesis gas is made by treating natural gas with steam.

Title: Improvements in and relating to machines for depositing articles or viscous liquids and the like upon trays or in moulds carried by a continuously travelling conveyor
IPC: A21B5/02
Filed: 1932-05-03
Abstract: 400,961. Endless - chain conveyers. BAKER, G. R. and BAKER PERKINS, Ltd., Hythe Road, Willesden, London. May 3, 1932, No. 12722. [Class 78 (i).] In a machine for making deposits of articles or viscous liquids such as chocolate, cream, or batters from a fixed point or transverse line in a series or group of consecutive rows in turn upon a series of spaced trays or moulds while the main body of the tray &c. conveyer is travelling continuously, the reciprocation of a portion of the conveyer 1 which is caused by an eccentric 15 is modified periodically by a cam 18 for the purpose of skipping the spaces between trays. The conveyer passes in a pair of oppositely disposed bights over chain wheels mounted upon a slidable carriage 8 and around fixed chain wheels which provide an unobstructed upper run as described in Specification 275,410, [Class 78 (i), Conveyers &c.]. A link 11 connects the carriage 8 to a lever 12 which is fulcrummed at 12a in one end of a slider 13, the other end of which is connected to an arm 20 pivoted at 21. The lever 12 is connected to the strap of the eccentric 15 by a connecting rod 14, and the arm 20 carries a roller 19 which engages a cam-grooved disc 18. If the shaft of the eccentric makes six revolutions to one of the shaft 17, then the action of the lever 12 will be modified after it has imparted six reciprocations to the carriage for the deposition of six rows on a tray, and the conveyer will be accelerated to skip the space between this tray and the next at the depositing station.

Title: D.c. motor control system
IPC: H02P7/00
Filed: 1970-03-17
Abstract: 1,272,364. Control of D.C. motors. AUTOMATION INDUSTRIES INC. 17 March, 1970. [1 April, 1969], No. 12782/70. Heading H2J. [Also in Division G3] A reversible motor 22 is connected to a rectifier bridge 140-146 which is in series with a further rectifier 268. The bridge rectifiers are controlled by a flip-flop 104 associated with a timer 100 which also causes the motor to stop at predetermined intervals and to have a set dwell period before starting in the reverse direction. Braking of the motor is controlled by feed-back from the bridge circuit. When transistor 160 is turned-off by timer 100, transistor 164 amplifies the signals from oscillator 162 whereby rectifier 180 conducts to turn-off transistors 190, 198. Transistor 212 is then forward-biassed by the reference voltage derived from network 200-204, uni-junction transistor 256 being enabled at a rate determined by the charging of capacitor 258. Rectifier 268 is then gated-on to complete the motor circuit through the selected bridge rectifiers. Increased motor current is detected by resistors 206, 242, to increase the forward bias of transistor 212 and advance the firing- point of the rectifier 268. While rectifier 268 is off, resistors 270, 272, detect the back electromotive force for regulating transistor 212 in a sense to stabilise the speed. Armature current reduction due to temperature changes are corrected by means of the resistor 242 associated with the transistor 212. Line voltage regulation is provided for by the stabilizing effect of the transistor 256. Transistor 198 provides protection against over-current. Limit circuits 290, 292 are enabled by a resistor 294 when a motor-driven carriage approaches the end of its movement. The flipflop 104 prepares transistor 116, for example, so that pulses from oscillator 118 forward bias the transistor so that transformer 122 applies pulses via accordancies 134, 136, to the gates of rectifiers 144, 146, the rectifiers 140, 142 being turned-off. The timer 100 enables transistor 160 to turn-off the rectifier 268, the armature voltage being discharged through diode 280 and resistor 286. A dynamic braking path is formed by the elements 146, 280, 286, and 144, transistor 160 being cut off at the end of the dwell period to repeat the sequence of operations. The motor 22 may reciprocate a search unit for ultrasonic testing of a workpiece which is immersed in a liquid. A carriage for the search unit is positioned on a bridge and is movable across the width of a tank in a scanning motion. A second motor moves the bridge in a longitudinal direction of the tank. Scanning takes place in a first direction, is stopped to allow movement by the second motor, and then occurs in a reverse direction.

Title: Resilient spacer for electrode joints
IPC: H05B7/14
Filed: 1969-03-11
Abstract: 1,215,103. Arc electrodes. UNION CARBIDE CORP. 11 March, 1969 [14 March, 1968], No. 12807/69. Heading H5M. In order to maintain good electrical contact between the adjacent end faces of joined arc electrode sections under conditions of thermal stress a resilient "expanded" graphite spacer is interposed between the end faces. Graphite electrode sections 10 and 14 are joined together by a convential nipple 12 and a recess provided in one or both end faces 22, 24 of the electrode sections contains an inner ring 16 of "edge" oriented graphite and an outer ring 20 of "flat" oriented graphite. The rings may be formed from spaced expanded graphite segments. The edge oriented graphite is more resilient and has a greater electrical conductivity in a direction parallel to the electrode axis than the flat oriented graphite. The expanded graphite may be expanded up to 25 times in the direction of the C-cryatollographic axis by conventional techniques or between 80-200 times by the method disclosed in Specification 1,049,588. Expanded graphite particles may be compressed by an amount which does not completely destroy their resiliency to form sheets. Metal powders or filaments, fibre glass, clay and up to 10% binder may be incorporated in the expanded graphite provided it does not impair its electrical conductivity or resilience.

Title: Improvements in or relating to centrifugal governors for internal combustion engines
IPC: G05D13/00
Filed: 1943-08-09
Abstract: 581,813. Centrifugal governors. NARKIEWICZ, V. Aug. 9, 1943, No. 12811. [Class 57] [Also in Group XXIX] A centrifugal governor for an internal combustion engine controls the flow of fuel under pressure from the main supply pipe to a bye-pass or drain by means of a valve actuated by a servomotor which is operated by the fuel pressure and controlled by a valve operated by the governor weights. The servomotor piston F, Fig. 1, is integral with the valve F<2> which in the normal (lowered) position shuts off communication between the main fuel supply pipe C<1> and a drain E. In this position, fuel from the main supply flows up the space N, through port G<2> in a fixed cylinder G, through a groove M in the valve H, and out through port G<1> where it assists spring L in keeping the piston F depressed. As the engine speed increases, the weights K swing outwards and depress valve H so that the fuel in chamber D<2> can escape through port G<1> into the governor casing ; and the pressure of the fuel in space N will lift the piston F and the valve F<2> to allow the main fuel supply to bye-pass through E. An aperture O<1> provides a leak-off for the space under piston F. The loading on valve H comprises an L-shaped lever S pivoted at S<1> and pressing on the underside of the disc H<2> on which the weights K act, and a spring P pressing on lever S. The lower end of spring P is clamped to a curved lever Q<1> which is pivoted at A<3> and which presses against and varies the effective length of spring P according to the setting of a cam disc R in contact with a roller Q<2> on the wedge. The arms K<1> carrying the governor weights K are pivoted to the ends of a pin B<1> passing through the driven spindle B. The friction between the lower ends of the weights and the disc H<2> will rotate valve H and prevent sticking. In a modification, a spring L\ Fig. 3, is interposed between the servomotor piston F<3> and the valve F<4> controlling the flow of fuel under pressure from the main supply pipe C<1> to the drain E. For normal speeds, valve H is raised and fuel from the main supply flows through passage N<1>, port G<4>, past the groove in valve H, and out through passage T to the top of piston F<3> to assist spring Ll in keeping valve F<4> closed. As the engine speed increases, valve H descends and the fuel over piston F<3> escapes through passage T and a port G5 into the governor casing. The pressure of the fuel in pipe C. will now overcome spring L<1> and valve F<4> will be forced open to allow fuel to drain through the venture E<1>. In this case, the lever S surrounds the stem of valve H and large movements of the lever are cushioned by spring-pressed plungers U which act on its free end. A non-return relief valve O<3> is provided for the space above piston F<3>. According to the Provisional Specification, the valve F<2> slides over and obturates V-shaped openings in a cylinder which encloses the valve. Specification 576,243, [Group XXIX], is referred to.
