Title: Bushing for a coupling such as a container closure and method for mounting such a bushing
IPC: B65D39/08
Filed: 1972-03-17
Abstract: 1381950 Making internally threaded bushings KONINKLIJKE EMBALLAGE INDUSTRIE VAN LEER NV 17 March 1972 [23 March 1971] 12617/72 Heading B3A [Also in Division B8] A bush comprises an internally threaded portion 1, a tapered part 3 with a radially outwardly directed flange 4 at its upper edge, and an outwardly directed thickened lower flange 6. Milling 5 is formed in the angle between the part 3 and the flange 4. The bush is applied from below into the collar 8 around the opening in the container wall, fitting with a slight clearance in which a gasket 9 is placed. The flange 6 engages the wall 7 at the bottom of the collar 8 and a frusto-conical mandrel 10 is lowered, deforming the upper section of the part 3 outwardly against the upper region of the collar 8 and bending the flange 4 over the upper edge of the collar by means of a shoulder 11 on the mandrel. The milling 5 grips the collar, preventing rotation of the bush. When the bush is applied to a thin-walled container (Fig. 4, not shown), the collar is shaped so that the bush abuts snugly against it, and the upper edge of the collar is bent over with the flange 4 as the mandrel descends. In modifications the milling is provided on the upper region of part 3 and on the outwardly facing edge of the flange 4. although this latter milling may be omitted and a label ring may be provided around the outside of the collar.

Title: Improved process and apparatus for coating fabrics with liquids
IPC: D06M15/05
Filed: 1946-04-26
Abstract: 611,275. Coating webs. COURTAULDS, Ltd., and SOUTTER, R. R. April 26, 1946, No. 12619. [Class 140] Knitted or woven fabric to be coated with cellulose by passage through an aqueous bath of a regeneratable cellulose derivative such as viscose, followed by treatment with a coagulating agent, is treated with live steam immediately before immersion in the coating bath, to eliminate or reduce absorbed air and hence the occurrence of air bubbles in the final product: As shown a cotton fabric 1 passes over a fixed rod 2 down an entry shaft 3 into a steam chamber 4 where it is treated with live steam from jets 5, and thence down an exit shaft 6 into a viscose container 10 in which it passes around a freely mounted roller 13 and through centralising rods 14 to a screwadjusted exit slot 15. The steam chamber 4 and shafts 3 and 6 are surrounded by a steam-jacket 8 which is insulated from the viscose bath by a cork washer 12. The fabric enters the viscose bath at the apex of a projection 11 to avoid vortex formation. A constant level of viscose is maintained with the aid of a ball float 19 in a float chamber 18. The slot 15 may be temporarily widened by operating a lever 17 if it becomes obstructed by flock, or a slub on the fabric. Specifications 24637/03, [Class 15], and 306,586, [Class 140], are referred to.

Title: Improvements in or relating to bobbin carriers for rapid braiding machines
Inventor: LUMPA PAUL
IPC: D04C3/14
Filed: 1958-04-21
Abstract: 872,107. Braiding-machines. SCHNELLFLECHTER BERLIN VEB. April 21, 1958, No. 12621/58. Class 74 (1). Counter-rotating bobbins 2 supplying the wires together forming the strand 12 supplied by their braiding machine carrier, are braked by the action of a spring 4 which presses their end faces together; and, as the tension in the wires tends to rise by reason of diminution in the diameter of the wire mass on each bobbin, a bight 17 of the strand forces a slide 9 to the left, against the action of a spring 15 and so, through a lever 7, forces a cage 8 containing the spring 4 to the right to compress the spring and so to reduce its braking pressure. The initial pressure of springs 4 and 15 can be adjusted by means of a nut 3 and a screw 16. In the event of breakage of any wire, that end coming from a bobbin is gripped by a device which normally gives it free passage. The devices may be leaf springs 21, spring-loaded wheels having fluted cams 25, 25a, or a roller, spring-urged against an inclined plane. Each wire passes to its gripping device via guide bushes or rollers.

Title: Frequency control of ultrasonic devices
IPC: H03L1/02
Filed: 1963-03-29
Abstract: 968,802. Electric correspondence control systems. AEROPROJECTS Inc. March 29,1963 [March 30, 1962], No. 12671/63. Heading G1N. [Also in Division B3] The frequency of the A.C. power fed to a mechanical, work-performing, vibratory device is controlled by a temperature-sensitive resistor to vary with temperature in the same manner as the resonant frequency of the transducer coupling, so as to maintain optimum power-developing conditions. As shown (Fig. 3) a temperature-sensitive resistor 18 is connected across the cathode biasing resistor 58 of a valve 52, whose anode is connected to the grid through resistor 64 and capacitor 62, 68 whereby the output appears to be an inductance in parallel with a resistance. This is fed across the tank coil 86 of an oscillator valve 88, so that an increase in temperature of resistor 18 increases the transferred inductive reactance and reduces the oscillatory frequency of valve 88. The work-performing vibratury device is an ultrasonic welding transducer (Fig. 2) comprising a slotted member 24 of a magnetostrictive metal, or an electrostrictive ceramic, having a coil 28 fed with the controlled frequency A.C. power, and a coil 30 to supply polarizing flux. The member 24 is attached to a conically-shaped coupling element 32, rotated by a shaft 39 which also drives an anvil 46, the metal members 42, 44 to be welded together being located between the anvil and the end of the coupling element 32. The temperaturesensitive resistor 18 is embedded centrally inside the coupler 32, or attached to its surface. Specifications 837,869 and 877,966 are referred to.

Title: Improvements in or connected with games of skill and the like operative with the aid of coin actuated mechanism
IPC: G07F17/38
Filed: 1924-05-23
Abstract: 236,344. Easton, M. J., and Wilson, W. G. May 23, 1924. Tivoli billiards and the like.-A ball propelled by a spring-controlled plunger B up a vertical shoot A depresses a dished sheet of brass G, Fig. 3, against a counterweight K, thereby completing an electric circuit which lights a lamp J or rings a bell to give warning that the ball is about to descend a shoot F. The shoot F is coiled about a tower formed in imitation of a lighthouse and is made of spiral wiring to give the ball a twist or spin. On leaving the shoot F at F<1> the ball drops between pins M, and the game is to catch it in a movable cup N carried by a rack which is traversed by a pinion rotated by a knob P. If the ball is caught it is passed from the cup N down a shoot to release a prize or token-delivery mechanism. A ball not so caught falls down an inclined trough Y to a baffle Z to be released by the insertion of a coin. The ball after freeing the prize-delivery mechanism is conducted to the plunger B so that the player gets a free shot. A coin inserted in a slot a<1> passes down a shoot g, Fig. 11, and presses down an arm l to raise the baffle Z. The prize tokens are stored in a column m and are delivered by pressing inwards a push piece W carrying a slide X, Fig. 9, provided with a circular hole x in which the bottom token rests. The winning ball falls into a collar T on a lever U which it tilts, thereby lifting an arm t out of a rack V and freeing the plunger W. The bottom token is delivered to a shoot communicating with an outside pocket X<1>. When the slide X is actuated a baffle d carried thereby is withdrawn from the collar T and allows the ball to drop to its starting position.

Title: Improvements relating to frequency or phase modulation
IPC: H03C3/26
Filed: 1941-10-02
Abstract: 551,764. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 2, 1941, No. 12764. Convention date, Oct. 2, 1940. [Class 40 (v)] Frequency or phase modulation is effected by applying a carrier wave in series with a reactance to the grid-cathode path of a valve, the reactance being in the cathode-leg, and the phase of the grid-cathode voltage is varied in accordance with the modulating signal by applying the latter to a grid to vary the mutual conductance. As shown in Fig. 1, the carrier from a source 8 is applied between earth and the control grid 12 of a pentode valve 10, which has a condenser C in its cathode lead. Modulating voltage from a source 6 is applied to the same or another grid to vary the mutual conductance and so to vary the anode-cathode current through the condenser C. This results in a variation in the phase of the grid-cathode voltage. The phase modulated wave may be taken from the plate circuit, and amplitude variations may be clipped off by limiters. The frequency may be multiplied before transmission. The condenser C may be replaced by an inductance, and two valves may be used one of which contains a condenser, and the other an inductance, in its cathode lead. The valve grids are then energized in parallel by the carrier source and in push-pull by the modulating voltage, their anodes being connected jointly to the output circuit, Fig. 5. (not shown). In Fig. 4, the grid and cathode oi the valve 10 are connected across a tuned circuit 30 which is transformer-coupled to a tuned circuit connected to the grid of a second valve 20. The carrier and modulating voltages are applied to the grid of the first valve 10, and the phase-modulating wave is taken from the anode circuit of the second valve 20. This arrangement reduces the incidental amplitude modulation. For producing true frequency modulation, the signal voltage may be pre-distorted.
