Title: Improvements in electrical capacitor
IPC: H01G2/10
Filed: 1965-04-01
Abstract: 1,105,262. Capacitors. GENERAL ELECTRIC CO. 1 April, 1965 [29 April, 1964], No. 13841/85. Heading H1M. In a capacitor of the wound foil type impregnated with a dielectric liquid 3 in which the flattened rolled capacitor section 2 is immersed, opposite side walls of casing 1 are compressed at 7 and 8 into contact with the capacitor section over a major proportion of its surface area. Compression of the wound foils prevents draining of the dielectric liquid 3 away from the inner part of the terminals when it contracts under low temperature conditions. This would otherwise lead to reduced dielectric protection around the terminals which would be aggravated by the low-pressure conditions thereby created. Because of the large area of contact between the casing and capacitor section there is good heat dissipation and further the size of the casing is not critical. The compression (Fig. 3, not shown) may be carried out before or after the dielectric liquid is introduced into the easing, and before or after the fill hole on lid 4 is sealed. The extent of compression may be regulated to give a desired capacitance value.

Abstract: 1,087,097. Rolling; stretching. METAL BOX CO. Ltd. March 9, 1966 [April 2, 1965], No. 14122/65. Headings B3E and B3M. A method of rolling metal strip 1 includes passing the strip in an S-shaped pass between fixed backing rolls 8 and 9 driven at different speeds, and between freely rotatable floating work rolls 10 and 11, the rolling load on the strip being produced by the tension in the strip. Feed rollers 2, 3, 5-7, and 13-16 are positively driven to tension and direct the strip, while a further, adjustable roller 12 stabilizes the position of the work rolls relative to the backing rolls without producing any reduction in the strip. Curved guides direct the strip around the rollers and sprays are provided for lubricating the strip. In order to facilitate initial threading of a strip the roll 10 is movable from the positions shown to a position approximately below the roll 11. To this end, the housings 30, Fig. 5, supporting each end of the roll 11 are provided with gears 31, each meshing through an idler 42 with a gear 41. Rotation of one spindle 43 of an idler 42 causes rotation of the adjacent housing 30 within a frame 38 and also of the other housing 30 by means of a tie rod 40 to which the gears 41 are attached. The roll 10 is supported in thrust bearings 28 in housings 128 which are themselves pivoted to the housings 30. The supporting spindles 35 of the gears 31 are positioned eccentrically with respect of the axis of roll 11. In alternative forms, the work rolls 10 and 11 may be of equal size, and the roller 12 may be positioned above the work rolls.

Abstract: 1467895 Automatic control of pressure COMBUSTION ENG Inc 1 April 1974 [2 April 1973] 14340/74 Heading G3R In the control of a plurality of actuators 40' 40", 40"' -, by means of corresponding control signals from units 54', 54", 54"' -, gates 60' 60", 60" are interposed, so that, unless they are opened by a signal from controller 57", no actuation can take place. As shown by-pass or atmospheric dump valves 40', 40", 40"' in the secondary circuit, Fig. 1 (not shown) of a nuclear powered electrical generating system are controlled to open in a predetermined sequence 54', 54", 54"' in dependence on a comparison between the actual working fluid H 2 O pressure P'2 sensed at 48' and a corresponding preset value P' sp . The working fluid-pressure is independently sensed at 48" for comparison with a pre-set value P sp " to provide an error signal PER", biased by unit 52" to ensure that a greater error signal prevails in the second channel, the error signal PER" being used to open gates 60',60",60'". No single system or operator error can thus lead to opening of more than one valve. The valves may enable the working fluid to by-pass turbine (32) Fig. 1, passing direct to condenser (34) whose effluent passes via pump (38) to heat exchanger (22) coupled to the primary circuit (18) including nuclear reactor (10), with core (12) and control rods and drive (14, 16).

Title: Improvements in counting and recording apparatus, more particularly for use with liquid meters
IPC: G01F15/06
Filed: 1931-05-15
Abstract: 367,650. Counting-apparatus. SEABROOK, H., 31, Bedford Street, Strand, London.-(Kienzle Taxameter-und Apparate Akt.-Ges. ; Villingen, Schwarzwald, Germany.) May 15, 1931, No. 14437. [Class 106 (i).] In a counting and recording instrument for liquid-dispensing apparatus wherein the counting and type-wheels are zeroized under spring action when a clutch is disengaged by operation of the impression mechanism, the clutch is prevented from reengaging by a locking-device until the counting- elements have completed their return to zero. The measuring movements reciprocate a plunger 3, Fig. 2, to advance a ratchet wheel 10 by means of a pawl 8. The wheel is fast with a sleeve 13 geared by spur wheels 16, 17, Fig. 1, with the total counter 18 and carrying non- rotatably a clutch member 19 adapted to engage a similar member 20 rigid with a gear wheel 21 driving the " trip " counter 48 by means of a wheel 52. Fixed to this wheel 52 is a wheel 53 gearing with a wheel 55 fixed to a shaft 54 on which are secured the quantity type-wheel 58 and the price type-wheels 59 easily removable for changing. A delivery having been made the operator rotates a shaft 32 to effect the following actions by means of cams. Firstly a cam 64 rocks a platen 61, pin-and-slot pivoted at 86 to the baseplate 1, so as to press a card against the type-wheels. Secondly a face cam rocks a lever to disengage the clutch member 19 whereupon a spring inside wheel 58 returns the trip counter and the type-wheels to zero. Finally a spring-urged rod 41 engaging a flatted cam completes the rotation of the shaft 32 to its normal position. To ensure completion of the zeroizing movement before allowing reengagement of the clutch, a lever 66, Fig. 6, is drawn by a spring 37 into contact with a snail cam 30 to stop rotation of the shaft 32 unless the lever has been raised by return of a pin 74 on the wheel 55 against a stop 70 on the lever. This stop is pivoted for one-way movement in case the delivery is sufficiently great to turn the wheel through more than one revolution.

Abstract: 369,068. Building motions for ring spinning and doubling machines. AKT.- GES. J. J. RIETER ET CIE, Winterthur, Switzerland. May 15, 1931, No. 14441. Convention date, May 17, 1930. [Class 120 (ii).] In a building motion for ring-spinning, doubling and twisting frames the stroke from the heart-shaped eccentric is modified before transmission to the rocking lever by a controlling element, which is displaced in accordance with a curved guide which moves as the cop increases in size. A heart-shaped eccentric 3 driven by a worm wheel 4 and worm 5 is mounted on a shaft 2 in a frame 1. A control lever 6 is free to swing on the shaft 2 and carries at its end a roller 18 which co-operates with a curved guide 19, 20 carried on a support 21 connected by a lug 22 to the spindle rail 23. A lever 8 mounted on a pin 7 at the middle of the lever 6 carries a roller 9 which co-operates with the eccentric 3. A roller 10 carried by a lever 11 connected by a screw 12 to the rocking lever runs on the back face of the lever 8. Thus as the cop grows the spindle rail and curved guideway fall and the pivot 7 about which the lever 8 turns is moved towards or away from the roller 10 so that the stroke of the heart-shaped eccentric is imparted to the lever 11, and hence the rocking lever 13, tie rod 14, chains 16, and ring rail 17 to a greater or less extent according to the shape of the curved guideway 19, 20. The control lever 6 may be arranged in the top portion of the machine frame and may be replaced by a control member, provided with the transmission lever 8 and pressed against the curved guideway by spring action, or the displaceable control member may simply shift the roller 9 between the eccentric 3 and the lever 11. In a machine where only the ring rail is displaced the guideway 19, 20 is connected to the ring rail.

Abstract: 666,089. Umbrellas. MAPPIN, W. L. June 1, 1950 [June 1, 1949], No. 14649/49. Class 134. In a folding umbrella comprising main ribs having two hingedly connected portions which, when the umbrella is open, are held in alignment by a slidable bolt which is movable to an inoperative position to permit folding and collapsing of the umbrella, the bolts are constructed from lengths of metal wire or rod bent into substantially circular form medially to provide bearings for the outer ends of the stretcher ribs. The umbrella stick comprises telescopic sections 1 and 2 having a plastic ornamental top 4 and a plastic handle 3 secured thereto. A circular notch component 5, provided with radial slots 5a in which the ends of the upper rib-sections 7 are pivotally secured by a tying wire 15, and a spreader block 6, having longitudinal recesses 6a in alignment with the slots 5a, are mounted on stick-section 1. The spreader block 6, in addition to preventing lateral displacement of the umbrella ribs in the closed position, also serves as a stop to prevent inward folding of the ribs across centre. To aid this effect, the recesses 6a may be formed to cause the rib-sections 7 to diverge slightly, or alternatively a spacer ring 13 may be fitted, as illustrated, together with a rubber cushioning ring 20 to prevent the runner 12 from being damaged by forcibly contacting the spacer ring 13. Each outer rib-section 8 is preferably of solid wire and is provided with an extension sleeve 8a formed with a pair of spaced apertured lugs 8b. A pivot pin 9 passes through the lugs 8b and bifurcated portion 7a of ribsection 7 which is of channel or " U " crosssection except for an end tubular portion which slidably houses a bolt member 10 having a circularly bent medial portion 10a, to which the stretcher 11 is pivoted, projecting through a slot 7b in the said tubular portion. A roller may be mounted on each pivot pin 9 to facilitate operation of the bolts 10. In the folded position of the umbrella, Fig. 1, the protruding ends of bolts 10 are confined by the handle 3. When opening the umbrella, Fig. 2, the bolts are moved by means of the slide 12 so as to enter the extension sleeves 8a and abut against stops formed by the inner ends of rib-sections 8.

Title: Process for the extraction and recovery of aromatic hydro-carbons from hydrocarbon mixtures
IPC: C10G21/16
Filed: 1953-05-26
Abstract: A plurality of aromatic hydrocarbons of the benzene series are separated from a mixture thereof with non-aromatic hydrocarbons by introducing the mixture into a counterflow multi-stage extraction system at an intermediate point, introducing a glycollic selective solvent, which is substantially immiscible with non-aromatic hydrocarbons, into one end of the system into extractive contact with the hydrocarbon phase therein, maintaining the extractive system under pressure sufficient to keep the contents liquid at a temperature above 40 DEG  C., preferably 80 DEG  to 125 DEG  C., withdrawing substantially aromatic-free and glycol-free raffinate from the same end of the system as that at which solvent is introduced, withdrawing the aromatic-rich glycollic extract from the other end of the system, pre-stripping said extract under evaporative conditions to liberate only the most volatile aromatic therefrom together with non-aromatics of equivalent volatility, condensing the so-liberated vapours and returning the condensate to the extraction system near its said other end, conducting the remainder of the extract to a heated zone, stripping the aromatic hydrocarbons from the solvent in said zone, subjecting the aromatic hydrocarbons to rectification and returning the substantially hydrocarbon-free solvent to the extraction zone. Suitable feedstocks are obtained by cracking aromatic or naphthenic petroleum or by catalytic reforming. The selective solvent is preferably diethylene glycol, alone or containing 0.5 to 10 per cent by weight of water, although ethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol and mixtures thereof may also be used.  The extraction system is preferably operated at a temperature above the boiling point of the most volatile hydrocarbon and the reflux stream is obtained by flashing the vapours of the said aromatic from the extract at a lower pressure in the pre-stripping zone.  In a modification, the pre-stripped vapours are fractionated to give an overhead portion rich in non aromatics which is condensed and returned to the extractor at a point nearer the middle than the point at which the aromatic bottoms are returned.  The main stripper may be operated at atmospheric pressure or under vacuum, preferably with injection of small amounts of steam.  The hot solvent drawn from the bottom of the still is returned to the extractor and maintains the desired extraction temperature therein.  Examples are given of the treatment of a gasoline having a boiling range of 150 DEG  to 300 DEG  F., and obtained by "Platforming," with diethylene glycol containing 2 per cent of water as the selective solvent, using a 10 : 1 solvent to feed ratio at an extractor temperature of 50 DEG  to 60 DEG  C. Specification 718,909 is referred to.
