Title: Liquid fuel preheater
Inventor: EVANS WILLIAM BASIL
IPC: F23K5/20
Filed: 1963-02-15
Abstract: 1,064,744. Heating liquids in bulk. MIDLAND COMBUSTION Ltd. Feb. 5, 1964 [Feb. 15, 1963], No. 6188/63. Headings F4S and F4T. [Also in Division G1] A temperature control device associated with a liquid-fuel preheater heater 1, e.g. of the kind described in Specification 997,022, comprises means 9 sensitive simultaneously to the temperature of the heated fluid at both the inlet 2 and outlet 3 of the heater for varying the amount of heat supplied to the heater. In the system shown, heated liquid fuel passes from the heater 1 through a connection 3 to the control device and thence through a connection 4 to a ring main system of burners (not shown). Surplus fuel supplied to the burners returns to the heater 1 through a connection 5, the control device, and a connection 2. The temperature-sensitive element 9 responsive to the temperature of fuel passing both from and to the heater 1 (i.e. in chambers 7, 8) may (as shown) comprise a thin-walled container filled with a volatile liquid such as acetone and connected through a bellows (not shown) to a valve regulating the heat supplied to the heater 1. Alternatively, the element 9 may comprise a bi-metallic element, a rod of material having a relatively high coefficient of expansion, or a pair of thermocouples the total signal from which is used to control the heat supplied to the heater.

Title: Improvements in the treatment and cutting of artificial filaments
Inventor: RAJCHENBAUM NIUMA BENJAMIN
IPC: D01G1/10
Filed: 1954-03-03
Abstract: 762,391. Preparing textile filaments for stapling. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 16, 1955 [March 3, 1954], No. 6206/54. Class 120 (3). Drawn and crimped filaments of synthetic linear condensation polymers such as polyamides and polyesters are prepared for cutting into staple lengths by drying and heating at a temperature above 100‹C. and, in the hot or cooled state, coating with a lubricant whilst spread, as by passage over a convex surface, into a ribbon assisted by an electrostatic charge on them. The heating (which may also constitute the setting stage of a filament crimping process) may be effected by collecting the filaments into drums which are placed in a steam-heated oven, or by advancing the filaments, as by means of a blast of hot air or steam, through a heating zone formed by a flexible tube which may be bent into a coil. The lubricant (or size or finishing liquid) may be applied by continuous spraying, and, if in the form of an aqueous solution, the water content is limited or reduced (by evaporation) to not more than 4 per cent. the coating of the filaments may be assisted by the electrostatic charge on the filaments or a charge imparted to the coating material. The charge on the filaments may be induced by passing the filaments through a tension gate or over a number of tensioning pins.

Computing-apparatus.-Relates to a machine of the kind described in Specification 27435/10 for weighing, counting or calculating articles by weight. A pivotally-mounted weigh-beam or steelyard has means connected therewith adapted to receive a predetermined total or standard weight, which may be interchangeable, and means co-operatively arranged with the beam for receiving the article to be counted, the latter means being neutralized on a traversable auxiliary beam so that only the actual weight of the article to be counted is transmitted to the beam. The beam 9 is fulcrumed on a knife-edge 10 in a bracket 8 secured to the sides of a track 7 carried by pillars 6, and a bearing-box 12 suspended from the short arm of the beam 9 receives the inter - changeable standard weight 13. A trolly 11 on the track 7 carries an auxiliary beam 17 from which the receptacle 18 is suspended, and a link 21 suspended from the link 20 carries a roller 22 which traverses the beam 9. The receptacle 18 is neutralized by means of a weight 26 and, when the beam 9 is balanced, the number of articles required to equal the standard 13 is shown on the beam 9 by the wire 28 of an eye-piece 27 carried by the link 21. The link 21 is pivoted to the link 23 carrying the receptacle 18, and is also connected by means of a stay 24 to a member 25 on the bracket 16. A brake-shoe 29 operated by a nut 30 on the screw 31 is provided for locking the trolly 14 upon the track 7.

Abstract: 801,511. Reciprocating pumps. WILD & CO., Ltd., A. G. March 23, 1956 [March 10, 1955], No. 7084/55. Class 102(1). [Also in Groups XXIX and XXX] In a jack of the kind comprising a hydraulic cylinder and a ram slidable therein and a plunger pump for supplying pressure fluid from a reservoir to the cylinder by way of control valves 14, 17 which may be operated to permit release of the fluid from the cylinder, a manually operable lever 21 is rigidly connected to an arm 22 rotatable about a pivot 23 the axis of which is on or closely adjacent to the line of movement of the plunger 7, which plunger is so coupled through a connecting rod 8 to a point 10 in this arm that rod and arm constitute a toggle joint; straightened as the plunger moves towards its inner position. In order to prevent the lever 21 travelling over the first 15 degrees of its movement whilst pumping is being carried out (within which range it would operate valves 17, 14 to cause drainage of the cylinder) there may be used a stop similar to that of Specification 773,789 [Group XXIX], or there may be an L-shaped stop 11, movable from the position of Fig. 1, in which the lever 21 is retained in its rest position by engagement of a catch thereon with a short arm 11<SP>1</SP> of the stop, into the position of Fig. 3, in which it limits the swing of the lever. Alternatively, the pin 23 may have an eccentric central part which, by rotation of the pin in its housing, is translated between two positions, in one of which the pump plunger, in its innermost position, does cause drainage of the cylinder, and in the other of which the plunger does not. The pin 23 is located in its alternative positions by a rectangular plate 27 which it bears and which, under the influence of a spring 31, may engage with the appropriate arms of a cruciform recess 28. In either position, locating pins 33, 34 engage in corresponding recesses. An operating knob 29 is provided.

Pistons, balancing laterally; connecting-rods.- In pistons of the type in which the lateral thrusts are taken by spring-pressed rollers, the roller or rollers which take the thrust on the power stroke are not spring-pressed. The roller e, Fig. 2, which takes the thrust on the power stroke may be mounted between parallel webs on the piston head, or between extensions d of the piston skirt. The opposite rollers i may be carried by a spring-pressed lever mounted on a horizontal pivot, or, as shown, each roller i may be carried by a lever h, turning on a vertical pivot secured in bosses g on the gudgeon-pin bosses, springs j being interposed between the rollers h and bosses k on the extensions d. Alternatively, the power thrust may be taken by two rollers e, Fig. 5, carried by radial arms p on a stem q which carries the gudgeon-pin, the opposite thrust being taken by a single roller i carried by a spring-pressed lever m. The stem q is of such length that the rollers do not run on the part of the cylinder traversed by the piston heads.

Ethers specified are divinyl ether, ethyl vinyl ether, 2-chloroethyl vinyl ether, 2-hydroxyethyl vinyl ether, allyl ethyl ether, 2-methylallyl ethyl ether, 2-methylallyl n-propyl ether, 2-methylallyl 21-hydroxyethyl ether, di-(2-methylallyl) ether, 2-chloroallyl ethyl ether, di-(allyloxymethyl) ether and 2-methylallyl epoxypropyl ether. Organic peroxides, e.g., benzoyl peroxide alone or admixed with uranium salts such as uranium nitrate or acetate may be employed as catalysts. The co-polymers, which are gels, powders, soft porous solids or hard bone-like materials, depending upon the extent of polymerization and the proportions of vinylidene  chloride to ether, may be modified by the inclusion of plasticizers, fillers, pigments, colouring agents or other effect materials before or after polymerization. In examples, vinylidene chloride and either divinyl ether, 2-chloroethyl vinyl ether, 2-chloroallyl ethyl ether, di-(allyloxymethyl) ether, 2-methylallyl n-propyl ether or 2<SP>1</SP>-hydroxyethyl 2-methylallyl ether are heated in the presence of benzoyl peroxide.
