Abstract: 383,335. Automatic regulation. ELECTRICAL APPARATUS CO., Ltd. and BARBOUR, R. H., Vauxhall Works, South Lambeth Road, London. Aug. 28, 1931, No. 24254. [Class 38 (iv).] An electrical regulating system includes a thermal relay heated by a current varying with the quantity to be regulated and having contacts controlling regulating apparatus and means effecting a sudden change in the heating current to restore the relay to an inoperative position. The time interval occurring before the next operation of the relay is susceptible of adjustment. In the form shown in Fig. 1 the thermal relay 20 is heated by a transformer 12 the primary of which is connected in series with an impedance 13 across a circuit 4, the voltage of which is to be regulated. An 'impedance 16 is in parallel with the transformer primary. The rotor 5 of an induction regulator is adjusted by electromagnets 10, 11 controlled respectively by contacts 21, 26 of the thermal relay 20 through a limit switch 28. Each magnet at the end of its stroke opens a switch 14 or 17. The switch 14 opens the circuit of the primary winding of the transformer and permits the relay 20 to cool and the switch 17 opens the circuit of the parallel impedance 16 and increases the heating of the relay. In a modification electromagnets controlled by the thermal relay carry contacts controlling the relay heating circuit and others controlling linked relays reversing the current supply to the primary of a three-phase induction motor controlling on-load top changing switches of a transformer supplying the regulated circuit. Specification 365,669 is referred to. The invention is applicable to current regulation and to direct current circuits.

Title: Improvements in or relating to reversible internal combustion engines
IPC: F01L13/00
Filed: 1934-08-27
Abstract: 443,957. Starting, stopping, and reversing ; relief valves. WANS, O., and RUSTON & HORNSBY, Ltd., Sheaf Iron Works, Waterside South, Lincolnshire. Aug. 27, 1934, No. 24565. [Classes 7 (ii) and 7 (v)] In a reversible engine, the working or combustion or cylinder chamber b is provided with a loaded outwardly-opening relief valve c which is provided with pneumatic means for partly relieving the load on the valve during the stopping period, so that the valve then opens under the pressure of the air in the cylinder, allowing air to be forced into a receiver o against the pressure therein during the instrokes of the engine piston, but closes during the outstrokes of the piston. As shown, each cylinder head a is provided with a passage d leading to a socket fitted with a valve casing e having a guide sleeve f for the spindle h of the mushroom-type relief valve c. A heavy spring k is interposed between a screwed plug l in the end of the casing and a piston i bearing against a flange j on the spindle h. Between the head of the valve c and the piston i, a conduit n leads to the air receiver o. Two shut-off valves p, q arranged in series in the conduit n are controlled by cams r, s on the shaft of a hand wheel u. In one position of the hand wheel, for normal running, the valve p shuts off communication with the air receiver and the valve q opens communication between the relief valves and the atmosphere; the relief valves are then fully loaded by the springs k and open only under excessive pressure in the cylinders. In a second position of the hand wheel, for starting or reversing by means of air in the receiver o, the valves p, q provide through communication between the receiver o and the valve casings e to relieve the pressure of the springs k. A chamber y between the valves p, q is connected by a manifold v to cam-actuated distributing valves 1 leading to inwardly opening starting valves z on the cylinder heads, and the cams controlling the valves 1 are adjustable for " forward " and " reverse " starting. To stop the engine suddenly while running " ahead," the cams are set as for " reverse starting and the hand wheel u is set to open the valves p, q; air from the receiver is then admitted to the cylinders on the instrokes of the pistons, bringing the engine to rest and then reversing it, while the relief valves c open when the pressure in the cylinders exceeds that in the receiver o, returning the pressure air to the receiver. In modifications: (1) the valve p is replaced by two valves leading to two air manifolds each supplying a group of the starting-air control valves ; (2) the valves p, q are replaced by a single two-way valve ; (3) the valve q is omitted and pressure air in the pipe n escapes gradually after the stopping period.

Title: Improvements in the manufacture and production of condensation products
IPC: C09F1/00
Filed: 1929-08-12
Abstract: 339,958. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 12, 1929. Ester condensation products; albumens.-Oily resinous products are obtained by esterifying the hydroxyl groups of aliphatic long chain carboxylic acids containing hydroxyl groups in the chain, or esters of such acids with alcohols, by heating these materials with colophony or other natural resinic acids until and under such conditions that the acid value of the resinic acids has practically disappeared. The esterification may be effected in vacuo or the water mav be removed as formed by the passage of an inert gas; acid or alkaline condensing agents may be used. The almost acid-free viscous oily products are stated to be useful as softening agents. According to examples, the parts being by weight, (1) 150 parts of castor oil and 50 parts of colophony are heated at 260‹ C. under reduced pressure to yield a viscous oil. A still more viscous oil is obtained by employing 100 to 150 parts colophony for the same quantity of castor oil, which is readily miscible in paraffin oil. It is suitable as a softening agent for celluloid, condensation products of formaldehyde with urea or phenols, or casein. (2) A brown viscous oil soluble in most organic solvents except the lower aliphatic alcohols, is obtained by heating 15 parts ricinoleic acid with 13.5 parts colophony for 10 hours under reduced pressure. (3) 3.4 parts of dihydroxystearic ethyl ester are heated with 3 parts of abietic acid at 260‹ C. in vacuo until the acid value has been reduced to zero.

Abstract: 997,484. Radar. RAYTHEON CO. July 7, 1961, No. 24758/61. Heading H4D. In a frequency - modulated radar a receiver mixer 16 is fed with the signals derived from the target echo signals and with the output of a local oscillatoi 17, a discriminator 18 is arranged to produce a first control voltage 20, a phasesensitive detector 21 is fed with the A.C. component of the discriminator output and with a reference signal 25 synchronized with the transmitter frequency-modulation source 12 to afford a second control voltage 27, and the first and second control voltages are applied to a reactance valve 19 to so affect the frequency ol local oscillator 17 that the discriminator 18 output voltage tends to zero. A phase-shifter 24 in introduced to allow for phase lag in mixer 15. Target range is given by indicator 31. Dopplerfrequency change of the transmitted wave produces a D.C. voltage from the discriminator which affects reactance valve 19, such that the local oscillator " tracks " the Doppler frequency. The law of transmitted frequency variation may be sinusoidal. The invention avoids the minimum-range restriction in F.M. radars of the kind in which transmitter frequency deviation is varied to maintain a constant beat frequency; and it is stated that satisfactory range measurement over a wide signal-tonoise ratio is afforded. Phase modulation may alternatively be employed, and the transmitted signals may be continuous or interrupted. Specification 958,383 is referred to.

Abstract: 950,710. Retractive switches; switches held set and freed mechanically. NATIONAL ACME CO. June 28, 1962, No. 24899/62. Heading H2B. A switch with four pairs of fixed contacts 69, 70, 71 and 72 arranged in two sets to co-operate with double-throw bridging contacts 76 and 77, respectively, has actuating slides 38 and 39 with arms 61 and 62 whose positions can be easily altered to provide twelve different switching arrangements. Bridging contacts 76 and 77 are spring-loaded on insulating carriers 74 and 75 having extensions 80 and 81 positioned for engagement by L-shaped arms 61 and 62 and biased by springs 82 and 83 respectively. Slides 38 and 39 are urged by springs 55 and 56 respectively against rollers 34 and 35 carried on a rocker 31 pivoted at 21 and operable by a lever 25. The movements of the slides 38 and 39 are limited by stops 42 and 43 in the housing which engage notches 40 and 41 in the slides. The slides 38 and 39 are interchangeable and reversable and have grooves 44, 45, 46 and 47 in which arms 61 and 62 may be selectively secured by screws 64. Grooves 44 and 46 are nearer their respective ends of the slides than grooves 45 and 47 are to theirs. Corresponding grooves are provided on the opposite side of the slides for use when a slide is reversed in the housing. As shown, a ball detent 29 engages a groove 30 to locate the rocker 31 in a central position and movement of the arm 25 will cause depression of slide 38 or slide 39 according to the direction of movement and thereby changeover the contact 77 or 76 respectively. The position of arms 61 and 62 may be changed to reverse this junction (Fig. 7, not shown); or both arms may be secured to one slide to cause operation of both contacts 76 and 77 when arm 25 is moved one way and no actuation when it is moved the other way (Figs. 5 and 6, not shown). If a slide is reversed the greater distance of the grooves from the end of the slide engaging the rocker is such that bridging contacts 76 and 77 would normally be held midway between their associated pairs of fixed contacts and oscillation of lever 25 may depress the slide or allow it to rise for selective bridging of the fixed contacts. Both slides may be reversed to produce variations of this action on all the contacts (Figs. 8 to 11, not shown), or only one of the slides may be reversed to give various combinations of change-over and selective switching (Figs. 12 to 15, not shown). Appropriate grooves may be provided in rocker 31 such that it is detained in either limiting position.
