Title: Apparatus for wrapping articles
IPC: B65B9/02
Filed: 1963-02-06
Abstract: 972,585. Wrapping articles.  MASCHINENFABRIEK & CONSTRUCTIE - WERKPLAATS AWO. N.V. Feb. 6, 1963 [Feb. 6, 1962], No. 4902/63. Heading B8C. Apparatus for substantially continuously wrapping articles, comprises two sheets of synthetic resin material fed from rollers between two complementary half moulds 6, 7 and a moulding frame 5 which define cavities C, D and 11, the sheets being formed into U- shapes with flanges at the end of the arms of the U. The moulds 6, 9 are biased by springs 10 towards each other and frame 5 is supported from frame members 1, 2 by arms 8. The articles, e.g. sausages, pass through frame 5, acting as a nozzle, into the moulded sheets and a heated sealing element 14 descends to seal the longitudinal extensions of the sheets to form a tube, a fixed heating element 15 being provided. The elements 14, 15 are carried by a reciprocating trolley 13, 24 which travels with the tube during sealing. The tube passes subsequentally in direction of arrow 3, Fig. 1, to clipping presses to divide the tube into separate units, the transverse open ends are then sealed, air within the tube being evacuated.

Title: Improvements relating to alternating current voltage-responsive arrangements
IPC: G05F1/26
Filed: 1944-03-20
Abstract: 578,235. Valve relaying circuits. STONE & CO., Ltd., J., and NIXON, L. R. March 20, 1944, No. 5145. [Class 40 (v)] Consists of a bridge network of the type in which the output voltage reverses after a certain increase of input voltage associated with a valve so that a relay in the valve output circuit operates at a certain input voltage. As shown in Fig. 1, the bridge comprises resistance elements, two of which are non-linear, e.g. metal filament lamps so that as the input voltage V1 is increased, the output voltage V0 first increases, then decreases to zero at the bridge balance point and then goes negative. The bridge output voltage V0 is applied to the grid of valve 3 whose anode is supplied through transformer 4, the output taken from transformer 5 being used to control a relay or similar device. If transformer 4 is connected so that, below the balance point, the grid voltage V0 and the anode voltage are out of phase, no anode current will flow when V0 corresponds to cut-off of valve 3, but as V1 is increased between the cut-off point and the balance point, the anode current IA increases, Fig. 3a. Upon further increase of V1 through the balance point, V0 becomes in phase with V1 and IA increases to saturation. The normal working range, however, is between a point below balance and the balance point. To produce a decrease of anode current with increase of V1, the connections of transformer 4 are reversed so that V0 and the anode voltage are in phase below the balance point. The anode current will thus decrease, Fig. 3b, as V 1 is increased through the balance point, becoming zero when cut-off is reached. In this case, the normal working range is between the balance point and a point somewhat above. In a modification, Fig. 4, two valves 3, 3<1> are operated in push-pull, the bridge output being applied in reverse phase to the grids by means of auto-transformer 6 or an auxiliary valve amplifier. The output transformer 5<1> has two primary windings which excite the transformer in reverse directions during alternate halfcycles so that a smooth A.C. output is obtained. A direct current bridge, Fig. 5, comprising non-linear resistances 1 may be used, the input being supplied from transformer 7 through fullwave rectifier 9 and a filter. By including a non-linear resistance 8, a non-linear relationship between the instantaneous values of applied voltage and the current in the transformer primary is obtained so that the bridge always attains its balance point at the same r.m.s. value of the applied voltage. If this resistance is omitted, the bridge is balanced at a predetermined average value of the applied voltage taken over one-half-cycle.

Title: Improvements in or relating to bobbin-changing devices for looms
IPC: D03D45/20
Filed: 1926-02-23
Abstract: 248,010. Cohen. M. A., (Assignee of Bantle, K.). Feb. 23, 1925, [Convention date]. Shuttles, changing bobbins in, automatically.- The bobbin transfer is controlled by a weft feeler device acting when the bobbin is substantially exhausted, and also by the weft-fork mechanism acting on breakage of weft. It is stated, however, that in an alternative arrangement the weft fork mechanism may be caused to stop the loom. A warp protector or shuttle feeler is used to prevent bobbin transfer in case the shuttle is not correctly positioned, and a scissors device on the shuttle feeler cuts and clamps the weft end from the old bobbin when bobbin transfer occurs. Weft feeler arrangements. - The feeler device comprises two pins 3, 4, Fig. 3, of different lengths contacting with the shuttle wall and with the bobbin respectively. When the bobbin is substantially exhausted, a lever 7 is turned about its pivot by the pin 4 before it is moved back by a guide piece 6, so that when the lever 7 is moved back by the part 6 it engages and operates a flap 5 and operates lever mechanism 8, 14, Figs. 3 and 5, whereby a " rod " 13 is moved into the path of the weft hammer 12 and a shaft 14 controlling the bobbis transfer is turned. When the thread breaks, the weft fork " rod " 10 is operated and also causes the shaft 15 to be turned. Transfer mechanism; shuttle feeler devices. When bobbin transfer is indicated, a slotted " organ " or lever 31, Figs. 7, 11 and 12, is turned about its pivot 21 and by acting on a pin 29 moves a link 24 pivoted to an insertion lever 23 into the path of a lay dagger 26, whereby the lever 23 is operated and a hammer 27 thereon inserts a fresh bobbin from the magazine M into the shuttle. The magazine is provided with a bobbin-retaining spring 25. The lever 31 is provided with arms 32, 33, which engage the shuttle if it is wrongly positioned, whereby the lever is turned back and the link 24 is moved out of the path of the lay dagger so that no bobbin transfer occurs. Weft, cutting.-When the movement of the lever 31 and its arms 32, 33 is not interfered with by a wrongly positioned shuttle, a " rod " 38 on the lay engages an abutment 37 on a lever 35 pivoted between the arms 32, 33, whereby the lever 35 is turned. The weft end from the old bobbin, which has been cut by the temple cutter, is again cut by the scissors device formed by the cutting edges 36 on the lever 35 and fixed arm 33, whilst the weft is clamped at the points a between the lever 35 and the fixed arms 32, and consequently is prevented from entering the fabric.

Filed: 1960-02-15
Abstract: 880,590. Screw propellers. GRUT, H. T. Feb. 15, 1960 [Nov. 6, 1959]; No. 5234/60. Class 114. The blades of a screw propeller comprise a rod 2 attached to the hub 1 at 7, a port 4 movable along but not around the rod and having secured thereto a shell 3 formed as an aerofoil with an end piece 6 rotationally mounted on the rod 2, and means 8, 9, 10 for rotating the end piece 6 to adjust the angle of trust of the blade. Due to the torsional force applied by the adjusting means 8, 9, 10 the shell 3 and rod 2 will be elastically deformed and since the rod has greater rigidity than the shell, the angular displacement is distributed along the blade partly as a continuous twist of the shell and partly as a small angular displacement at the tip of the blade due to the twist of the rod 2. The adjusting means 8, 9, 10 may be manually or power operated (power operation being preferably connected to the speedometer of the vehicle), and is fixable in different positions by a locking device 11, 12, 13. The adjusting means may be disconnected and the rod 2 rotated about its axis 7 by means not shown, to turn the entire blade around its longitudinal axis e.g. when reversing or feathering the propeller. The shell may be provided with elastic supports, e.g. lengths of elastic material 14l, 14t along the leading and trailing edges.

Title: Improvements in or relating to electric resistors
IPC: H01C7/10
Filed: 1961-02-13
Abstract: 941,445. Semi - conductor devices. J. KEMENY, B. COSNUAU, M. JELENSPERGER, and F. KONYEVITS. Feb. 13, 1961 [Feb. 12, 1960], No. 5320/61. Heading H1K. A voltage variable resistor, represented by the equation consists of grains of silicon carbide in a metallic container without a binding agent, the container exerting on the grains pressure which determines the constants of the device. Fig. 1 shows an arrangement in which silicon carbide granules provided with a thin silicon oxide or aluminium oxide coating are compressed between electrodes 2, 3 in a " Bakelite " (Trade Mark) capsule 4 by turning over the ends of a metal tube 5. After manufacture the sides of the tube are in tension and this determines the compression on the grains. In arrangements described with reference to Figs. 4 and 5 (not shown), the casings are in two parts joined together by turning over a metal band while in the arrangement of Fig. 6 a resilient spring 6 pressing on electrode 3 determines the final compressive force on the grains. An arrangement is described, Fig. 7 (not shown), in which the granules are connected in series with a voltage source and a relay which cuts off the motor carrying out the compression when the current through the resistor reaches a prearranged value. The relay may also control a hydraulic valve. A liquid or powder insulator which also acts as a lubricant may be introduced between the grains. During compression excess is removed through fine holes in the container. The insulator may be hardened by drying after manufacture. Zinc stearate is suggested as a suitable powder.

Title: Improvements in mine signalling apparatus
IPC: B66B19/06
Filed: 1920-02-25
Abstract: 162,465. Hill, T. H. Feb. 25, 1920. Mine and colliery signals; mechanical telegraphs.-The setting of a transmitter A, of the ship's order-telegraph type, located at the bottom of a mine is transferred by a cord a to the central one of three coaxial discs g, h i forming a receiving-indicator B for the engineman. The two outer discs g, i are connected to the main disc h by coacting pins or stops in such a manner that special signals indicating, say, that " men are to be raised from a given " seam " can be initially shown on them, and remain displayed during the subsequent backward movement of the transmitting-handle b preliminary to the sending of the main signal to the disc h. A pin r, Fig. 3, on the disc h thrusts a hanging link t against a pin s carried by the disc i, which is thereby rotated until the pin s arrives at the extreme end of the lever t. A shoulder v<1> on a lever v then drops over the pin s and locks it in position with the word " men " showing at the aperture q. To cancel this sign, the transmitting handle b is given a full forward movement, rotating the disc h until the pin r passes under a cam v<2> on the end of the lever v, which is thereby raised to free the pin s and allow the weighted disc i to swing back to normal position. Similarly the second disc g. Fig. 6, is rotated from the disc h by means of ccntacting pins w, x, the disc being held in the set position by means of a detent lever z engaging stops y. All signals may be cancelled, automatically or otherwise, say on completion of the order, by means of a handle a<4>, Fig. 1, which rotates a cross-shaft a<1> carrying lifting-lugs a<2>, Fig. 3, and a<3>, Fig. 6, which release the detent levers v, z and free the discs g, i from their settings. Gongs may be fitted to both receiver and transmitter to give audible warning of each signal. Several receivers may be connected in series with one transmitter.
