Title: Device for the automatic changing of bobbins in looms
IPC: D03D45/20
Filed: 1924-07-22
Abstract: 220,612. Olivier, L., (Assignee of Polet, L., and Laforet, J.). Aug. 13. 1923, [Convention date]. Shuttles, changing bobbins in automatically.- The bobbin change is effected during the forward movement of the lay by a spring-controlled vertical charger 25, Fig. 3, carried by the lay, the lowest bobbin in the magazine 30 having been taken therefrom by a spring-controlled horizontal slide block or transporter 26 to a position beneath the charger. When the weft breaks &c., a spring controlled shaft 5, Figs. 3 and 6, is turned, and by means of a lever 28 a lever 27 is turned so as to actuate the transporter 33 in which the bottom bobbin from the magazine is retained by springs 32 cooperating with a trap 33. A lever 19 on the shaft 5 carries a roller 20 engaging a pivoted finger 21 provided with a rod 23 engaging a vertical spring-controlled lever 15, pivoted on a lever 18. When the shaft 5 turns, the lever 15 is moved by spring action into the path of a screw 14 on a cam controlled lever 11, and the lever 18 is thus turned. As the lay moves forward, an inclined part 18<1> of the lever 18 acts on the charger 25, which is thus depressed and transfers the fresh bobbin into the shuttle. The charger remains in contact with the shuttle until this departs. The lever 11 may be actuated by a cam on the main shaft, as is shown, or by a cam on the cam shaft, or by a roller on the lay. A modification is described wherein the lever for actuating the charger is operated by a spring-controlled lever on a cam-controlled lever. If the shuttle should be incorrectly positioned in the shuttle box, it engages a part 21' of the finger 21 and moves this into position to prevent bobbin transference. The weft ends pass through an eyelet and between two pinions pressed together by a spring, one pinion being rotated step by step, each time bobbin transfer occurs, by ratchet mechanism.

Title: Improvements relating to caramel wrapping machines
IPC: B65B51/00
Filed: 1927-07-01
Abstract: 298,175. Martin, H. E. July 1, 1927. Stream-cutting machines. -Relates to caramel cutting and wrapping machines, such, for instance, as are described in Specifications 215,902, [Class 94 (i), Packing &c.], and 223,708. The caramel material 2<a> is fed and shaped by two rollers 1, 2, Figs. 1 and 2, intermittently rotated by an arm 4 and Geneva stop motion 3 and gears 49 - - 51, and is passed along a channel 9. A constantly rotating knife 10 severs a portion, which is thrust, with a wrapper, through guides 19, 20 into the recess 21 of an operating arm 22 by a pusher 18 in such a position that the cut ends are at right angles to the surface engaged by the pusher. The pusher member is pivoted at 23 on an arm 24 which is positively moved in each direction by cams 26, 30. The operating arm 22 descends past a guide 53 which folds up the outstanding portion of the wrapper and the caramel is ejected into a holder 32 adjacent to a pair of continuously rotating gripping devices 33 for twisting the ends of the wrapper. The jaws 34, 35 of the devices are open when the ejection of the caramel into the holder takes place, being opened against the action of springs 62 by levers 36 acting on rack bars 61 co-operating with gears 60 on the jaws. The levers 36 move outwards to allow the jaws to close upon the projecting ends of the wrapper during the twisting operation, and the action of the levers is adjustable by means of locking nuts 38 so that the wrapper is allowed to slip during the twisting to compensate for lateral movement and to obviate mounting the jaws to reciprocate longitudinally.

[Also in Division F2]  A method of making a finned tube comprises making cuts in a web of stiff, bendable material, the cuts 2 extending from one edge of the web to a line A-B parallel to the longitudinal axis of the web, bending the material 3 between the cut out of the plane of the web in a common direction, and winding the web into a helix by bending the remainder of the web about oblique lines XY extending from the inner ends of the cuts to the other edge of the web to form an externally finned tube, Fig. 2. The material may be a metal, a polymetallic construction, a plastic or a fibrous material such as resin impregnated paper. The tube is made fluid tight by overlapping or subsequently making fluid tight by conventional means. The width of the remainder of the web may be a multiple of the pitch of the helix preferably three times. Flat tubes can be made by making the cuts wide as shown in Fig. 1. or polygonal crosssection tubes having more than six sides may be made without widening the cuts. The bending of the material 3 may be on a line parallel to A-B or normal to the oblique lines XY. After completion the tube may be given a twist about its longitudinal axis, Fig. 13 (not shown). The fins may be deformed to produce turbulent flow in a fluid moving past them. The web may be slightly embossed to promote adhesion of overlapping surfaces. When a metal web is used it may be coated with a layer of solder or adhesive or a ribbon of viscous adhesive dispersed between the overlapping surfaces during winding, followed by a heattreatment.

Filed: 1933-06-24
Abstract: 405,182. Generating combustion products under pressure. BROWN, E., 8, Bahnhofweg, Baden, Switzerland. June 24, 1933, No. 18099. [Class 51 (i).] To enable a motor-driven rotary blower to accelerate readilv on sudden increases of load in quick-reaction high pressure steam generators an auxiliary supply of air is provided which on such increase delivers either to the combustion chamber or to the delivery pipe from the blower. The air may be taken from an air main or from one or more reservoirs, which are charged from a main or a small blower which may be driven with and use air supplied from the main blower ; each reservoir may be only large enough for one action, and they may be arranged in series or parallel. The main blower may be driven by waste gases used in an exhaust turbine ; the auxiliary supply of air when used will then temporarily augment the power available for acceleration sufficiently to enable the air delivery from the blower to exceed the normal requirement. The air if of very high pressure may be in part expanded in a turbine to help drive the main blower. The valve 40, Fig. 5, controlling the supply from the reservoir 36, may be opened by an engine-driven centrifugal governor, through a fluid relay 43 whose piston acts on a curved lever 44 connected to the valve stem ; the curvature is designed to give quick opening and the abutment 47 on which it rolls is adjustable. In another arrangement an eccentric 72, Fig. 7, oscillates a rod 71 carrying a block 70 ; the end of the rod 71 is adjustable by the governor to enable the block to strike a valve lever 80. In another arrangement a fluid governor comprising a spring loaded disc 50, Fig. 6, acts through a cataract device 55 on a fluid relay 65 which opens the valve ; by adjustment of the bye-pass 59 between the two ends 57, 58 of the cylinder of the cataract the relay may be arranged to work only on large sudden movements of the disc 50 corresponding to great variation in load on the boiler &c.

Abstract: 439,977. Telephone &c. transmission. STARR, A. T., 73, Lansdowne Road, Notting Hill, London, and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. June 19, 1934, No. 18180. [Class 40 (iv)] [See also Group XL] By the use of known phase-correcting networks the phase-shift of a received complex wave may be made a linear function of the frequency, that is, the phase-shift=wA+C, where A, C are constants. This condition is generally sufficient in telephony, but in picture transmission, television and like systems it is necessary for the received wave to be an exact replica of the transmitted wave. The Specification gives a mathematical discussion which shows that this is the case if C is an integral multiple of #, and the invention therefore provides a circuit for shifting the phasecharacteristic of the. received wave as a whole so as to obtain this result. In Fig. 3 the received wave passes through an attenuation equalizer E and phase-correcting network P of known type to a modulator M where it modulates a high-frequency supplied by an oscillator O. One sideband, with or without the carrier, passes to a demodulator D which receives also the unmodulated carrier with a phase-lag produced by a phase-shifter P<1>. It is shown that the output of D has the same components as the input of M with a constant phase-lag, and the latter can be adjusted so as to make C in the equation above an integral multiple of #. If the received wave is in the form of a modulated carrier, the simplified circuit of Fig. 4 is used. The demodulator D receives the carrier and one sideband from a filter F which suppresses the other sideband, and the carrier alone with a phase-lag introduced by P<1> from a filter CF, which may be fed from either side of F. The filter CF may comprise a tuned circuit or a saturated amplifier, while the phase-shifter P<1> may be a simple resistance-capacity combination in the grid circuit of the amplifier. In the case of very short waves a first demodulation stage may precede the circuit shown so that one sideband may be more easily suppressed.
