Title: Improvements connected with direct current dynamo electric machines for use as electrical governors, and electrical governing systems
IPC: G05F1/00
Filed: 1944-11-23
Abstract: 583,728. Automatic control systems ; equalising load. WHEELER, H. D., and MOSSAY, P. A. H. Nov. 23, 1944, No. 23323. [Classes 35 and 38 (iv)]. A temperature compensated D.C. machine for use as an electrical governor has a pair of externally excited shunt windings in opposition, the positive winding incorporating a series connected ballast resistance of zero temperature coefficient. In one form, the machine G has shunt windings F1, F2 controlled by a regulator R, the resistance B giving temperature compensation. In a modified form, the field windings are connected in series through a ganged regulator, the ballast resistance shunting the negative winding. The machine may be used to maintain the speed of an engine or motor by virtue of the difference between its voltage and that of the supply energizing the field or armature of a pilot motor or contactor system P. Alternatively, by the use of further exciting windings in series with the motor any speed-torque characteristic can be obtained. In Diesel-generator sets the pilot motor can govern the generator field to load the engine so that it runs at constant speed and thus supplies constant power. Electronic amplification may be used. The ballast resistance may be of an alloy known as " Ferry " composed of 40 per cent nickel and 60 per cent copper.

Abstract: 961,052. Chain or belt epicyclic gear; variable-speed epicyclic gear. L. P. KAMM. June 28, 1961, No. 23398/61. Headings F2D and F2Q. In a chain or belt epicyclic gear an endless chain or V-belt a is driven by a planet b journalled on a constant speed input eccentric y and drives an output sun c of greater diameter than the planet which latter is non-rotatably connected to a plate p through perpendicularly arranged pin and slot means g, k, I, t comprising an intermediate member h. A reduction gear may comprise several such gears serially arranged. With the plate p and hence the planet b held from rotation, e.g. the plate p may be fixed, the output sun is driven at reduced speed. On rotation of the plate p in the same or opposite direction to the input eccentric the speed of the output sun is respectively correspondingly increased or reduced. Plate p rotation may be effected by a lever n, as shown, particularly for temporary arrest of the output sun in conveyer drives, or the plate p may have peripheral teeth so as to be rotated, for extended periods, in either direction, through suitable gearing. The eccentric y is keyed on a shaft s which may be an electric motor shaft, and the output. sun c may be mounted on an independent output shaft or, as shown, be journalled on the shaft s by a sleeve v and have an output coupling slot z. The chain or belt may comprise single, duplex, as shown, or multiple chain, or double or multiple track V-belt with suitable sprockets or pulleys. The planet b may be counterbalanced. The pins g, t may comprise antifriction rollers or be replaced by sliding blocks.

Patent GB-988091-A (GB)
Title: Condition responsive fluid flow monitoring and control system
IPC: G05D7/06
Filed: 1961-06-29
Abstract: 988,091. Reciprocating pumps. BROOKHIRST IGRANIC Ltd. June 29, 1961 [June 29, 1960], No. 23542/61. Heading F1A. [Also in Divisions H2 and H3] Relates to a system in which an electric motordriven pump of the reciprocating type is adapted to pump oil from a well during productive intervals and to discontinue pumping during alternate non-productive intervals, and to afford time for well-recovery during such non- productive intervals. Energization of timer 44 through contact 46a eventually closes contact 44a to operate relay 2CR whereby motor 18 starts pump 32. Timer 44 is set to close contact 44a for a predetermined period and to reclose the contact for such interval at certain times of the day. The rate of flow of oil is detected by means of thermistor 26, the temperature and resistance of which changes in accordance with the oil-pulses to provide alternating voltage across potentiometer P. When contact 44a opens, control of the motor is transferred to relay 1CR and pumping continues as long as there is sufficient oil in the well. Decrease of the flow-pulses reduces the positive pulses applied to the base of transistor TR1 which is rendered non-conductive to allow capacitor C4 to accumulate a charge and render transistor TR2 conductive. As a result, transistor TR3 conducts to shunt the coil of relay 1CR to deenergize the latter, thus stopping the motor until another pumping cycle is started by the timer 44. Alternatively, closure of switch 50 provides a time interval between the deenergization of relay 1CR and de-energization of relay 2CR to prevent the pump being stopped when gas in the oil causes relay 1CR to be deenergized. Closure of switch 50 energizes timer 48 which is so arranged that intermittent deenergization of relay 1CR for short periods does not cause interruption of the pump. Another method of operation is provided by moving switch 46 to engage contact 46b. With this arrangement, the pump is operated during each cycle until the oil-flow decreases and these running-times may vary. Timer 44 is stopped at the end of the initial period when control is transferred to the relay 1CR, and remains stopped until the relay is de-energized. When the relay is de-energised, timer 44 is re-started to time the well-recovery period. Another pumping cycle is initiated at the end of such recovery period.

Abstract: 1,108,672. Cartridge-actuated tools. HILTI A.G. 2 May, 1966 [3 June, 1965], No. 23626/65. Heading B4C. An apparatus for securing identification plates 91 to articles such as hot metal billets comprises a remotely-controlled cartridge-actuated fastener driving tool 24 having a block 93 for locating the plate and carried by a support 92, the latter being movable so as to bring the block to a working position from an inoperative position. The tool includes a driving plunger 43 slidable in a barrel 33 which is mounted in a casing 24 and provided with a cartridge chamber 50; the portion of the barrel adjacent the cartridge chamber is held against a firing pin guide 52 by means of a manually-actuated catch 59 so that by releasing the catch the tool pivots about a pin 27 and exposes the chamber for loading. The support 22 is mounted on a carriage (13, Fig. 1) which is movable on rails (11) towards and away from a metal billet (86). In operation, a nail 89 together with a washer 90 is inserted into the block 93 which is connected to a sleeve 39 slidable in the barrel 33 against the action of a spring 40. An identification plate is then positioned on the block 93 and held in place by a magnet (48, Fig. 3). Manual and foot actuated switches are operated and the carriage moved so that the block 93 is pressed against the side of the billet, the block moving inwardly until a further switch (73, Fig. 3) is actuated thereby energizing a solenoid 62. A striker 67 on the armature 63 then strikes the firing pin 51 to fire the cartridge. A pair of identical tools are mounted on the support so as to drive a nail into each end of the identification plate. In modifications the carttridge may be fired by electrodes instead of the solenoid-operated firing pin or by hydraulic, pneumatic or mechanical means.

Title: Improvements in the preparation of dialkali derivatives of dimerized aliphatic conjugated olefins or dimerized vinyl aromatic hydrocarbons and their conversion into dicarboxylic acids
IPC: C07C51/15
Filed: 1956-08-01
Abstract: In the process for selectively reacting a conjugated diolefin or a vinyl aromatic hydrocarbon with finely dispersed sodium or potassium in a reaction medium consisting substantially of an aliphatic monoether having a methyl group and an oxygen : carbon ratio of not less than 1 : 4 or an aliphatic polyether including those derived from aliphatic polyhydric alcohols having all the OH groups replaced by O-alkyl groups and mixtures thereof at a temperature below 0 DEG C. to form the di-sodium or di-potassium derivatives of the hydrocarbon dimers, the sodium or potassium is used in excess of that theoretically required for mol/mol. reaction but not in excess of more than 15 per cent.  Other factors-the presence of an aromatic polycyclic hydrocarbon and a solid friable attrition agent-are as in earlier cases.  The di-alkali derivative may be carbonated, hydrolysed and hydrogenated to give dicarboxylic acids containing two more carbon atoms in the chain than were present in the dimer, e.g. butadiene is dimerized to give disodio-octadienes which in turn give a mixture of sebacic acid, 2-ethyl suberic acid and 2 : 5-diethyl adipic acid.  Specifications 756,385, 761,842 and 771,329 are referred to.
