Title: Improvements in or relating to balanced protective arrangements for electrical systems
IPC: H02H3/30
Filed: 1926-04-26
Abstract: 276,701. Brown, W. J., Field, A. B., and Metropolitan-Vickers Electrical Co., Ltd. April 26, 1926. Cut-out arrangements. -In a balanced protective system of the Merz- Price type (using pilot wires or a wireless link) the capacity or charging currents in the main lines are compensated for by associating with the current-sampling devices means deriving from one or both ends of the main system compensating voltages or currents related at all times and in all conditions of the main system to the charging current bv the same law as are the sample currents to the main line current, and adding these compensating voltages or currents (with reversed signs) to the currents derived by the current-sampling devices. In the arrangement shown in Fig. 1 in which the wireless link is used (as in Specification 252,036) the current transformer 9 in the phase 1<c> and supplying, through its secondary 28, exciting current to the valve oscillator 2 has an additional compensating winding- 29 connected across the phases 1<a>, 1<b> through a high non-inductive resistance 30 so that the current therein is in phase with the voltage across 1<a>, 1<b> and therefore in phase with the capacity current flowing in the line 1<c> by reason of its capacities to earth and to the other two lines. In an alternative arrangement, Fig. 2, the compensating winding 29 is connected between phase 1<c> and earth through a swamping reactance. In order to deal with complex transient capacity currents as well as normal capacity currents of line current frequency the arrangement shown in Fig. 6 is used in which a current-sampling device 36 is associated with the line conductor while a second current-sampling device 37 having similar characteristics is connected between the line and ground through a condenser 38 the impedance of which is high compared with that of 36. The output sides of the sampling devices are connected in series opposition to the pilot wires or other link. The application of this arrangement to the wireless form of link and to threephase lines by means of artificial condenser networks is described. Specifications 252,810, 254,770 and 254,771 are referred to also.

Filed: 1952-05-07
Abstract: The invention relates to polyoxyalkylene ethers of hydroxy alkyl oxazolines having the general formula <FORM:0720611/IV (b)/1> wherein R1 is an aliphatic hydrocarbon radical of from 7-17 carbon atoms, R2 is hydrogen or methyl, R3 is -CH2- or -C2H4- and A represents a poly oxyalkylene radical containing 2-20 oxyalkylene groups selected from oxyethylene, oxypropylene and mixtures of oxyethylene and oxypropylene groups.  The ethers may be prepared by condensing appropriate fatty acids R1COOH in equimolar proportions with ethers of amino alcohols having the formula HO-CH2-C(NH2)(R2)-R3-A-OH with removal of two molar proportions of water, condensation being effected, e.g. at 150-240 DEG  C.  Preferably, however, the desired ethers are prepared by reacting the appropriate alkylene oxide or mixed oxides with the appropriately substituted 4-hydroxyalkyl-oxazoline, advantageously at elevated temperature and pressure in the presence of an alkaline catalyst.  The products may be used as detergents, wetting agents, penetrants, emulsifying agents and corrosion inhibitors (see Group III).  In examples, 2-heptadecenyl-4-methyl-4-hydroxymethyl-2-oxazoline is reacted in an autoclave with the alkylene oxide in presence of sodium methylate whereby two, six, ten or fourteen oxyethylene units, ten oxypropylene units, or twelve oxyalkylene units made up equally of oxyethylene and oxypropylene groups are each introduced to form oxyalkylene ethers. Other oxazolines mentioned as starting materials are 2 - heptadecyl - 4 - methyl - 4 - hydroxymethyl - 2 - oxazoline, 2 - hendecyl - 4 - hydroxyethyl - 2 - oxazoline, 2 - heptyl - 4 - methyl - 4 - hydroxymethyl - 2 - oxazoline and mixtures of oxazolines in which the R1 substituent corresponds to the hydrocarbon radicals of the mixed fatty acids of naturally occurring fats and oils or of tall oil.ALSO:Mineral oils are rendered non-corrosive in presence of moisture by means of polyoxyalkylene ethers of hydroxyalkyl oxazolines of the general formula <FORM:0720611/III/1> wherein R1 is an aliphatic hydrocarbon radical of from 7-17 carbon atoms, R2 is hydrogen or methyl, R3 is -CH2- or -C2H4- and A represents a polyoxyalkylene radical containing 2-20 oxyalkylene groups selected from oxyethylene, oxypropylene and mixtures of oxyethylene and oxypropylene groups.

IPC: F28G3/06
Filed: 1925-05-04
Abstract: 260,311. Kennedy, D., and Anderson, A. C. May 4, 1925. Cleaners for mechanically removing incrustation.-An apparatus for cleaning boiler tubes, condenser tubes, &c. comprises chains a jointed together at a<1> and attached to a spindle c rotated by connecting a flexible or other driving-shaft to a socket c<3> so that the chains fly out by centrifugal force and conform to the shape of the tubes &c. to be cleaned. The spindle comprises an inner rod c and a tube d capable of relative longitudinal movement so that the chains may either occupy the positions shown or may be stretched out flush with the' surface of the tube d. This relative movement is effected by rotating a shaft f which carries worms f<1> gearing with wheels f<2> mounted on a cross-head e fixed relatively to the rod and engaging by means of spindles f<3> with a bracket freely mounted between flanges s on the tube, so that movement of the spindle f causes the tube d to rise or fall. A yoke h is mounted on the bottom of the rod c and carries a bracket h<2> between which and a bracket g<2> rods k are carried, the arrangement being such that the apparatus can be movably supported on the boiler tubes by the engagement therewith of rollers g<1>, l, g<3>, h<3>. By causing the chains to be straightened out, the tube sheet itself can be cleaned. The chains may be arranged in pairs opposite each other, may be loaded at their pivoted ends, may be stiffened by spring wires extending along them to conform them to the shape of the tubes, and may be of sufficient length to clean three or more tubes on each side of the rod and to wrap half round each tube. The cutting-edges may be constituted by extensions of the links. In some cases the means for drawing the chains inwards is dispensed with.

Abstract: 1,159,375. Labelling machine; feeding webs; endless conveyers. RHONE-POULENC S.A. 11 March, 1968 [16 March, 1967], No. 11716/68. Headings B8A, B8F and B8R. An apparatus for applying labels supplied from a continuous reel to cylindrical articles comprises a rotatably mounted reel 1 of label strip, an intermittent brake and drive mechanism 6, 7, 8 for feeding the label strip 1A in response to signals from a device 5 for detecting the position of the labels, means 13 for cutting a label from the strip when stationary, a pregummed collector 16 for picking up a severed label, a rotary transfer cylinder 21 having an at least partly perforated periphery to which vacuum can be applied, means 23 for removing a label from said collector to enable it to be picked up and held by the vacuum on the transfer cylinder 21, means for feeding articles between the transfer cylinder 21 and a counter pressure member 24, and electrical control means for synchronizing the operation of the brake/drive assembly and cutting means 13 with the position of the label strip 1A and the position of the collector 16. In response to a signal from the detector 5 which senses e.g. notches in the label strip 1A, the drive means 7, 8 is disconnected and the brake 6 applied. A label is severed from the stationary strip 1A by the cutting device 13 and is picked up by the collector 16 which has been previously gummed by the roller system 17. The label is lifted away from the collector 16 by a finger 23 engaging in a peripheral groove in the collector 16 and is picked up by the vacuum apertures of the transfer cylinder 21. It is thus held until the cylinder has rotated to a position where the vacuum is cut off, and the label is transferred to a cylindrical article which has meanwhile been synchronously fed between the transfer cylinder 21 and the counter-pressure member 24, by the conveyer means 27, 28. After application of the label the article is rotated about its cylindrical axis by conveyer belts 29 to ensure a firm securing of the label to the container. The cutter 13 may be replaced by a cutting wheel or hot wire and the control of the brake 6 and the roller 7 may be effected by pneumatic, hydraulic or electrical means. The detecting device 5 may detect the presence of a notch in the label strip by means of a jet of air supplied by the device impinging on the diaphragm of a pneumatic capsule which actuates a contact in an electric circuit controlling the feed of the lable strip. Alternatively the detector device may be a mechanical device, or a photo-electric device detecting a difference in luminosity or an electrical or magnetic device detecting an electrical or magnetic discontinuity respectively in a coating on the label strip. In an alternative arrangement the apparatus disposed upstream of the cutter may be arranged in a substantially vertical plane, the cutting being effected in a substantially horizontal plane.
