Abstract: 793,368. Knitting-machines. MELLOW BROMLEY & CO., Ltd. Dec. 22, 1955 [Jan. 3, 1955], No. 135/55. Class 74 (2). Each trick of a needle bed of a knitting- machine is lined by a channel-shaped member 5 which accommodates the needle, Fig. 4, or alternatively a number of channel-shaped members may be soldered together in groups and secured to a plain base to form the needle bed, Fig. 8. The member 5 which is folded up from a metal blank is widened at its outer end to form a verge bit VB and has its outer edge slightly undercut so that it is rearwardly inclined. Where the member is accommodated in a trick 2 in a bed, the outer widened end may engage beneath projections 1b formed in the bed in order to position it. The rear end of each member is recessed to provide butts 6 which are secured by a plate 11 secured to the bed. Alternatively the members may be adjustably secured in position to move the verge bits VB into or out of the tricked bed when desired to compensate for the any variation in the yarn being knitted. For this purpose cams may engage the butts 6 to move the members.

Title: Improvements in and relating to incandescent and other electric lamps and similar devices
IPC: H01R33/05
Filed: 1937-01-04
Abstract: 471,301. Two-part couplings. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 4, 1937, No. 207. Convention date, Jan. 2. [Classes 36 and 38 (i)] An incandescent lamp or the like having the cap 24 formed as a part of the wall of the bulb or envelope 20, is located accurately by seating a shoulder 29 of the cap in a corresponding recess 30 in the holder 32, and retaining the lamp in the holder by resilient fastening means. If the lamp contacts 25 are circular, the fastening means may consist of resilient plates 45, Fig. 2, having keyhole shaped slots for engaging a neck on the contacts 25 by an inserting and turning movement, the turning movement serving also to bring the contacts 25 into resilient jaws 47 forming the holder contacts. The plates 45 are bent to form detents for the pins and to ensure quick-action engagement and disengagement of the contacts. If the contacts are of flat section their ends may be bent to engage beneath resilient bent blades in the holder that form both the contacts and retaining means. If the flat lamp &c. contacts are straight they may be retained in socketlike contacts 71<1>, 72, Fig. 16, in the holder (shown as an adapter) by spring-pressed balls 73 that engage holes in the lamp &c. contacts. The edge 30b of the holder forms the abutment for the lamp &c. cap which is rabbeted. Such a rabbeted cap may be used with an internally shouldered holder. The lamp contacts 25 are sealed into the base of the bulb by providing a skirt 33, Fig. 3, on each contact, the edge of which is fused into the bosses 35 surrounding the lead-in apertures 28. The skirts are thin enough to give resiliently under heat expansion and have tapered edges, and are made of an alloy having a coefficient of expansion near that of the glass such as the alloy known as Fernico, described in Specification 357,665, [Group II]. The skirts may be integral with the contacts or may be brazed thereto by means of a copper ring. Specification 435,663, [Group XI], also is referred to.

Abstract: 1,089,964. Automatic circuit-breakers. CTS CORPORATION. Jan. 4, 1965 [Jan. 8, 1964], No. 240/65. Heading H2B. [Also in Division H1] In a combination device comprising a variable resistor 15 (Fig. 4), a snap-action switch 35, 36 and an overload circuit-breaker 41, 41b in series with the switch, the bi-metallic element 41b of the overload breaker is reset by longitudinal movement of a common shaft 11 which movement causes movement of the switch bridging contact 35 to open the switch. To reset the breaker the end 11b of shaft 11 deflects an integral tongue of a plate 52 to bend the free arm of the bi-metallic element of the breaker back to the point where, if the overload conditions have disappeared, its hooked end 41b clips on to the fixed contact shown. Shaft 11 can then be retracted so that bridging contact 35 is moved to close the switch (Fig. 2, not shown). The resistor is varied by rotation of shaft 11. In normal operating conditions the switch is operable by shaft 11 without disturbing the circuit-breaker and may have operating means additional to but linked with the shaft. The series electrical connections between the resistor, switch and circuit-breaker may be external to the casing.

Title: Improvements in or relating to apparatus for feeding liquid fuel to internal-combustion engines
IPC: F02M69/00
Filed: 1946-01-07
Abstract: 624,856. Spray carbureters. VANNI, P. G., ETIENNE, M., WAVRE, J., and FABRIQUE DE BOITES LA CENTRALE. Jan. 7, 1946, No. 625. Convention date, Jan. 10, 1945. [Class 7 (iii)] Liquid fuel is fed to an engine by means of two continuous delivery pumps arranged in series and driven at a speed proportional to engine speed, the first pump delivering excess fuel to' the ,second. Fuel from a gear pump 1 passes through a gas separator 5 to a second gear pump 9 the excess fuel and separated vapour returning through a spring pressed valve 6 and pipe 32 to the fuel tank 2. The pump 9 delivers the fuel through a pipe 12 having a piston controlled byepass 33 to a metering valve 15 comprising a coni-. cal piston 16 operated by a lever 27 in conjunction with the throttle valve 24 and controlling the fuel port 14. The metered fuel flows through a distributer 21 to injectors 22, 23 in the intake pipes leading to the cylinders. The spring loading of the valve 6 is increased as the throttle is opened by means of a sliding cylinder 30 operated by the lever 27. Opening of the throttle 24 causes a pressure drop on the outlet side of the pump 9, and due to the slackness of this pump extra fuel for accelerating is forced through by the first pump. At starting, movement of the lever 27 past the full throttle position opens a port 38 to allow extra fuel from the first pump to bye-pass the second pump.
