Abstract: 1,042,641. Transformers. GENERAL ELECTRIC CO. Jan. 1, 1964 [Jan. 2, 1963], No. 60/64. Heading H1T. [Also in Divisions G1 and H2] In a ballast transformer for a fluorescent lamp circuit at least the secondary winding is wound without inter-layer insulation, the conductor insulation being such and the winding being so designed that at a frequency of 60 cycles and a temperature between 140 and 180 C. the value produced by dividing the power (in watts) dissipated in the conductor insulation by the product of the volume of conductor insulation in the winding (in c.c.s) and the weight of the conductor (in Kg.s) is less than 1À6. Both primary and secondary windings P 6  S, (Fig. 12) may be wound without inter-layer insulation on an elongated shell core, the laminations of which are secured by end clamps 92, 93 (Fig. 11, not shown). Extra secondary windings H 1 , H 2 , H 3  may be provided. The windings may be carried on phenolic bobbins or cylindrical paper spools 95 (Fig. 10) with inner paper insulation which can be turned up between the end turns and the core. Paper in wrappers 98 may be provided and capacitors may be encased in the potting material 82. The Specification describes the fluorescent lamp circuit (see Division H2) and methods of determining loss in insulation (see Division G1). The insulation coating of the conductor wire may be as described in U.S.A. Specification 2,085,995.

Abstract: 1304821 Endless conveyers TOKYO SHIBAURA DENKI KK 1 Jan 1971 [12 Jan 1970 5 Dec 1970(2) 64/71 Heading B8A The handrail of an escalator or moving walk way is provided with a drive arrangement wherein the handrail is gripped between drive and idler rollers, the grip being increased as the drive force is increased. The arrangement comprises fixed guide members 6, 7 arranged on opposite side of the handrail and floating carriages 8, 9 interposed between the respective guide members 6, 7 and the handrail. The carriages are coupled together by a pin and slot coupling 10, 11 which allows relative movement of the carriages towards and away from one another. The carriage 9 mounts idler wheels 16a-16d to bear on the one side of the handrail and rollers 9a, 9b to engage the guide member 7. The carriage 8 mounts drive rollers 12a- 12d arranged to engage the other side of the handrail and grip the same in combination with the rollers 16a-16d. The carriage 8 further mounts a pair of cam followers 18 for engagement with cams 6a in the guide member 6. In operation the reaction between the cam and the cam follower is formed of two components, one being the reaction of the driving force and the other resulting in the gripping of the handrail between the drive and idler rollers such that as the driving force is increased the gripping force is increased. The drive rollers are coupled by a common chain 15 and one drive wheel 12a is connected through an intermediate sprocket and chain system to a motor (19) Fig. 1 (not shown). In an alternative embodiment, Fig. 6 (not shown), the cam follower (118a) and cam (6a) are associated with the carriage (9) and the drive chain (12) is coupled directly to the middle pair of rollers (112b), (112c) which in turn are coupled to respective outer rollers (112a) (112d). In a further embodiment, Fig. 9 (not shown), each carrage (8), (9) mounts a pair of drive or idler rollers (112a), (112b) and (116c), (116b). In yet a further embodiment, Fig. 11 (not shown), idler sprockets (215a)- (215d) are interposed between the drive rollers (212a)-(212e) and the drive chain (220) passes in a zig-zag fashion around the sprockets (215a)-(215d) and sprockets (214a)-(214e) mounted on respective rollers (212a)-(212e).

Abstract: 1531241 Machining safety devices STERLING METALS Ltd 5 Jan 1976 [3 Jan 1975] 218/75 Heading F2J A mill or mixing machine 1, for mixing foundry sand, having a sand discharge opening 3 controlled by a pneumatically operable vertically slidable door 4, cannot be started until a detachably mounted guard hood 8 is secured in position, over the discharge opening 3, to close a magnetic switch 17. Two further magnetic switches 19 associated with an interlock 20 for a mesh top door 21 of the mill 1 are connected in series with the switch 17 (Fig. 6, not shown) whereby all three switches must be actuated before the mill motor can be started. An additional curved guard door 13 is pivoted by trunnions 14 within the hood 8 and is normally gravity closed when the machine is inoperative as shown chain-dotted in Fig. 3, the guard door 13 being outwardly pivoted, during operation of the machine, by the discharging flow of sand which exits through an open outlet 12 at the bottom of the hood 8. One of the trunnions 14, by which the guard door 13 is pivoted, extends through its bearing and carries, in an extended casing 33, 34 outside the hood 8, a switch operating arm 32 which co-operates with a magnetic switch 35 such that when the guard door 13 is opened by discharging sand the switch is actuated to energize an audible or visual alarm 36. To prevent removal of the hood 8 while the door 4 is open, i.e. raised, an interlock is provided comprising a pair of spaced upright rods 27 connected by a crosshead 28 to a lug 6 in the door 4, the rods 27 extending upward through guides 29 in the top wall of a shoot 7 adjacent the hood 8. Lugs 30 secured to the top of the hood 8 have holes which are aligned with the rods 27 when the hood 8 is in position, the arrangement being such that when the door is shut, the rods 27 are clear of the holes in the lugs of the hood 8 which can thus be readily removed but when the door 4 starts to open the rods 27 engage the lugs 30 to prevent removal of the hood 8, the rods entering tubular guards 31 fitted above the guides 29. The door 4 is controlled by a pneumatic piston/cylinder assembly 5 which is connected through pipes 37 to a pressure source 23 by a solenoid valve 24 controlled by push-button switches 25, the electric supply for the valve 24 being obtained from the motor side of the starter for the driving motor of the mill 1 so that the door 4 cannot be opened unless the hood 8 is in position.

Abstract: 369,305. Ascension pipes. MACINTOSH, A. A., 25, Bendigo Avenue, Elwood, Victoria, Australia. Jan. 5, 1931, No. 394. Convention date, Jan. 21,1930. [Class 55 (ii).] In fuel distillation plants wherein the gaseous products passing through the ascension pipe are subjected to two successive condensations, the gaseous pressure in the retort is automatically controlled. The oil obtained from the second condensation is separated and may be returned to the retort ; steam produced in the first condensation may be used for steaming the retort. The pressure in the retort may be controlled by the regulator of Specification 105,563, [Class 55 (ii), Gas manufacture &c.]. Volatile products from a retort 11 pass to a water-cooled ascension pipe 13, which operates as a reflux condenser, and gas and lighter oils pass on to a second condenser 23, condensates from the latter collecting in a chamber 26 and flowing to a separator 32. The separator comprises two sections 34, 35 each provided with outlet pipes 36, 37 having adjustable sleeves 38, 39 to regulate the liquid levels therein and each communicating with chamber 26 by pipes 31, 40. Liquor is passed into each section of the separator according to its density and such that liquor collects in the section 34 and flows into the pressure regulator 29 and oil collects in the section 35 to be used as desired. The pressure regulator comprises two compartments 42, 43, the liquor pipe 36 from the separator terminating in the open compartment 43, and the gas pipe 27 from the chamber 26 in the closed compartment 42. The latter communicates with the gas main 30 ; the former is kept at constant liquid level by having an adjustable sleeve 50 on an outlet pipe 49. The level of the liquid in compartment 42 varies with the pressure in the gas main and serves to maintain atmospheric pressure in the pipe 27 and the retort. In a modification two separators may be used in order to deal automatically with oils heavier or lighter than the liquor.

Abstract: Colours are produced on metal surfaces succeptible to the action of sulphide ions by dipping in a solution containing free sulphide ions, withdrawing before the sulphide film which forms is thick enough to give a uniform colour effect, immediately arresting further action of the sulphide solution (e.g. by plunging into a large volume of cold water), and drying the washed surface.  The film may be protected by applying a coating of transparent lacquer.  Specifically disclosed is the colouring of leaves plated with copper or silver by dipping in a solution of liver of sulphur, plunging into cold water, and drying in a current of warm air.  Iron surfaces may also be treated; ammonium hydrosulphide solutions are alternative sulphide solutions that may be used.
