Title: Improvements relating to voltage regulating apparatus for alternating current circuits
IPC: G05F1/32
Filed: 1946-02-15
Abstract: 608,108. Automatic voltage regulation. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. Feb. 15, 1946, No. 4805. [Class 38 (iv)]  In voltage regulating apparatus of the kind comprising two magnetic circuits and provided with an input winding or windings connected to an A.C. supply, and secondary windings connected in series opposition with one another and in parallel with a series connected condenser and inductance across the load circuit, one of the magnetic circuits being operated at a relatively high flux density above the knee of the B-H curve, the effective permeability of this latter magnetic circuit is arranged to be varied in order to vary correspondingly the basic magnetic condition or characteristic at which regulation is effected. The basic magnetic flux may be derived from a permanent magnet associated with the circuit. The invention is applicable either to single phase systems or to the polyphase system described in Specification 584,420. Fig. 2 shows an arrangement wherein one transformer T2 has auto-connected primary and secondary windings divided into two parallel connected portions carried on the outer limbs of a three-limbed core, the primary windings being in series with those of transformer T1 across the supply terminals 1, 2. The winding arrangement is such that no alternating flux due to the alternating current in these windings traverses the centre limb of the core. The centre limb carries an auxiliary winding 5 which is energized with D.C. current supplied through a rectifier unit V fed through a small transformer T3 connected across the A.C. supply 1, 2, an adjustable resistance R being provided to vary the current through the winding 5. Alternatively, the rectifier unit V may be fed from an auxiliary winding on the outer limbs of the transformer T2. In a modification, Fig. 3 (not shown), the rectifier unit V is arranged to inject a direct current into the primary and/or secondary windings on the outer limbs of transformer T2. A further modification, Fig. 4 (not shown), has the autotransformer primary and secondary windings on the centre limb of transformer T2, and an auxiliary winding 5 in two series connected parts on the outer limbs energized with D.C. from a rectifier unit. The ripple voltage developed in the auxiliary winding is rectified and increases the saturation of the core, thereby increasing the sensitivity of the control exercised by the direct current fed to the auxiliary winding. Specifications 548,526 and 597,371 also are referred to.

Title: Improvements in and relating to the manufacture of capsules
Inventor: CROWTHER HAROLD ALBERT HADLEIG
IPC: B65B9/02
Filed: 1951-03-01
Abstract: 712,485. Packaging. CROWTHER, H. A. H. Oct. 11, 1951 [March 1, 1951], No. 5013/51. Class 94 (1) A method of producing a series of charged and sealed capsules with the aid of intermittently downwardly fed opposed lengths of thermoplastic web or strip material comprises forming each of successive capsules by first joining the opposed webs to form a sac, then charging the sac through the open top thereof and following displacement of the webs, sealing the sac to close the capsule, the said joining and sealing being effected by di-electric heating, the welding members being U-shaped electrodes across which the high frequency power is applied, the electrodes sealing the last formed sac as they form the sac of the next capsule along the webs. Opposed webs 6 of thermoplastic material are fed intermittently from rolls 25 between di-electric heating sealing jaws 11, 12 which seal the strips together along the two longitudinal edges and transversely to form a sac which is filled with a measured quantity of material from a tube 9 extending between the strips, the top closure of the filled sac forming the bottom closure of the succeeding sac. The chain package so formed is moved intermittently downwards by feed means comprising a reciprocated slide 30 to which is pivoted a member 32 arranged to swing in and grip the chain package on downward movement of the slide 30 and to swing away on the upward movement. The heatsealing means 11 is generally U-shaped to co-aperate with the heat-sealing means 12 which is slidably mounted in its carrier 18 and is spring-urged away therefrom, such movement being limited by stop nuts 23. The heat-sealing means 12 comprises, Figs. 6, 7, two side bars 15 to form longitudinal side seals 7, Fig. 15, of a length greater than that of the package, so that succeeding seals overlap longitudinally, but not extending to a transverse seal 4, which is formed by a cross bar 16. The bar 16 has an obtuse angled edge 41 to ensure that the seal is thinner along its centre line so that the packages may be easily. separated. Sealing elements 24 of the means 12 form a tear space 42 in the package. Multiple chain packages with side-by-side packages having tear bands between them may be formed. The tear bands may be formed in a separate operation and may be partially slit. Marginal slits may be formed in the capsules outside the seams. Discontinuous tear bands may be formed. The electrodes may impress indicia on the packages. Trapezoidal packages may be formed.

Title: Rubber antidegradants
Inventor: WILDE BERTRAND ERNEST
IPC: C08K5/18
Filed: 1958-02-17
Abstract: In rubber there is incorporated, as antidegradant, a compound of the formula:  <FORM:0852932/IV(a)/1> where R1 is an aliphatic or aralkyl group and R2 an alkyl or cycloalkyl group containing 6 or more carbon atoms or an aralkyl group, and where the benzene ring may contain an inert substituent, or a salt of one of these substituted anilines. The preferred anti-degradants are those where R1 is a primary, secondary or tertiary lower alkyl group, a cycloalkyl group or a benzyl group, R2 a primary or secondary alkyl group, a cyclohexyl group or a benzyl group and where the benzene ring is unsubstituted in the positions ortho to the amino group but may bear for example alkyl groups in the meta positions.  The anti-degradent may be used in natural or synthetic rubbers in an amount between 0,5-2% by weight.  Examples describe compositions based on pale crepe rubber, smoked sheets and styrene-butadiene copolymer, and physical properties of the compositions containing specified anti-degradants are given.ALSO:The invention comprises N-substituted anilines of the formula:  <FORM:0852932/IV(b)/1> where R1 is an alkyl, cycloalkyl or aralkyl group and R2 is an alkyl or cycloalkyl group containing 6 or more carbon atoms and where the benzene ring can contain an inert substituent, and their salts, provided that where R2 contains 6 carbon atoms R1 if an aralkyl group is a benzyl group and where R2 is a cyclohexyl group the total number of carbon atoms in R1 and in any inert substituent of the benzene ring is at least 2.  The compounds may be prepared by reductive alkylation of an amine <FORM:0852932/IV(b)/2> (or a suitable nitrogen-containing precursor of the amine, e.g. a nitro, nitroso, azo or hydrazo compound) in the presence of an aldehyde or ketone from which the group R2 can be derived by reduction.  The reductive alkylation may be carried out catalytically by means of hydrogen.  The compounds may also be prepared by alkyllating the N-unsubstituted aniline with an alkyl halide R2-hal preferably in the presence of an acid-acceptor.  Salts, e.g. quaternary chlorides or hydrochlorides may be prepared in the usual manner.  The compounds find application as rubber anti-degradants (see Group IV(A)). Examples describe the preparation of the following substituted anilines:4-ethoxy-N-11, 31-dimethyl-n -butyl, 4-ethoxy-N-cyclohexyl, 4-benzyloxy-N-11, 31-dimethyl-n-butyl, 2-methyl-4-methoxy-N-cyclohexyl, 4-ethoxy-N-n-hexyl, 4-methoxy-N-n-hexyl, 4-ethoxy-N-n-hexadecyl, and 2, 6-di-methyl-4-methoxy-N-n-octyl-aniline.  Benzyl-4-nitrophenyl ether is prepared from potassium p  p-nitrophenate and benzyl chloride. 2-methyl-4-methoxy-azobenzene is prepared by treating sodium m-cresate with phenyldrazonium chloride and methylating the resulting 2-methyl-4-hydroxy-azobenzene.  2,6-dimethyl-p-anisidine is prepared by coupling 3,5-xylenol with sodium benzenediazotate to give 3,5-dimethyl-4-phenylazophenol which is methylated to 3,5-dimethyl-4-phenylazoanisole and then reduced.

Title: Improvements in price-change mechanism for prepayment meters and the like
IPC: G07F15/08
Filed: 1946-02-18
Abstract: 608,194. Prepayment mechanism for meters. VENNER TIME SWITCHES, Ltd., and HORGAN. W. F. Feb. 18, 1946, No. 5027. [Class 27] Price-change mechanism.-In a fine and course price-change gear comprising a stack of graduated gears 1 selectively connected to a pair of elongated pinions 16, 17 by connecting gearing in carriers 18, 19, each of which can be traversed along its pinion to select the gear required after pivoting it about its pinion to break the mesh, a common element serves so to pivot both carriers together whilst independent adjusting devices are provided for traversing them. In the mechanism shown, each carrier 18 or 19 has a pair of intermeshing idlers, one 20 or 22 in constant mesh with its pinion 16 or 17. and the other 21 or 23 engageable with the gear stack 1. Pivotal movement of each carrier is controlled by a rod 33 along which it slides in traversing the pinion, and this rod depends from a lever 18a or 19a pivoted on the pinion axis and urged by a spring 38 to bring the carrier idler up to the gear stack 1. The common element for pivoting the carriers comprises a pull-out slide 41 provided with lateral arms 40 for engaging pins depending from the levers. For traversing the carriers each has a knurled nut 35 engaging a fixed threaded rod 36. Access to these elements is obtained through a cover 49 and, in making an adjustment, the slide 41 is first pulled out by means of a key applied to a pin 43 at its forward end, the knurled nuts 35 are then turned to bring the carriers opposite sections of the gear stack 1 corresponding to the new charge rate as indicated by pointers 47 against scales 48, and the slide 41 finally thrust back to re-engage the carrier idlers 21 and 23 with the gear stack. Alternatively, the cover 49 may engage and return the slide 41. The depth of engagement of the idlers with the gear stack is controlled by stepped plates 51 against which tails 50 of the carriers bear to limit their inward movement. The gear stack 1 is driven through gearing 15 by the meter or coin mechanism, whilst the pinions 16 and 17 are connected through gearing of suitable ratio to one sun-wheel and the planet-carrier of a summating differential. the other sun-wheel of which is connected through gearing 30, 32 with the quantity mechanism. A spring-actuated toothed locking lever 46 engages gear 32, when the carriers are rocked to break the mesh in order to prevent the quantity-mechanism running back. In the zero adjustment position of each carrier, its idler is engaged with a fixed gear 24 coaxial with the gear stack 1.

Abstract: 1,243,958. Control of A.C. motors. SULZER BROS. Ltd. 5 Feb.. 1970 [6 Feb., 1969], No. 5597/70. Heading H2J. [Also in Division G3] A servo system comprises a reversible induction motor which adjusts valve 5 through gear or hydraulic transmission, the valve spindle being coupled to a position transducer 7 supplying a signal to logic circuit 10. A comparator 44 receives the signal i as well as a reference signal s and forms a deviation signal a which is amplified to provide signal b. A transmitter 46 receives the signal and a preset signal e which adjusts the limit G1 required for the appearance of an output signal c for switching on the motor. A further correcting signal d depends upon the length of time the motor has been switched on to allow for the inertia of the moving parts. It is triggered by the signal c which is inverted and integrated. The sum of the signals b and d decreases in accordance with the duration of the signal c until the motor is switched off at the limiting value G2. The switching off time of the motor is displaced as the length of time the motor has been switched on increases. The signal c is applied through AND gate 49 to store 53 associated with AND gates 54, 55 for controlling SCR switches 57. 58 through trigger circuits 56, 59. The sign of the signal a determines which of the switches 57, 58 will be triggered. A D.C. source 25 is provided for braking the motor, the said source being connected to the stator winding when the A.C. supply is removed The D.C. voltage is reduced when the motor comes to a stop. A current measuring network 15 provides a signal for switching off the motor when a current limit is exceeded. The current limit is increased for a predetermined period when the motor is being started, this period being prolonged if the valve is near its closed position. If an over current is indicated when the valve is not near its closed position, an alarm is given. A limit 30 compares the instantaneous voltage in the supply lines S and T and provides a signal m for switching the motor on or off only if the instantaneous voltages are equal and positive.
