IPC: C30B15/22
Filed: 1960-09-09
Abstract: <PICT:0900562/III/1> The diameter of a rod being pulled from a melt is controlled by an electrostatic field produced by a ring electrode around the solid-liquid interface.  The rod may be of silicon or genmanium. In the former case, the component of the field strength normal to the rod should be at least 5 kv./cm.  As shown, a rod 1 is pulled from a molten drop 2 adhering to a rod 3, rod 1 being surrounded at the solid-liquid interface by a ring electrode 14 in electrical communication therewith via a direct current source 15. Drop 2 is maintained molten by an induction heating coil 4 and the drop is replenished by upward movement of rod 3.  Pulling is effected in a vessel 16 containing a vacuum or a protective gas atmosphere. The capacitance between the rod and the ring electrode, which is proportional to the diameter of the rod, may be measured and utilized to control further the diameter of the rod by varying the speed of pulling or the strength of the electrostatic field.  In a further embodiment (not shown), a rod is pulled through a perforated diaphragm from a molten mass in a crucible.

IPC: B65C3/10
Filed: 1922-11-14
Abstract: 210,559. Flower, A. L. Nov. 14,1922. Labelling; sheet separators.-In apparatus for labelling bottles &c. in which labels are taken from a holder by a pneumatic device mounted on a reciprocating carrier and arranged to rotate therein, so as to present the label first to a gumming-device and then to the article to be labelled, the suction device is rotated by means of a Geneva-cross device mounted on the carrier and engaging with fixed pins; arrangements of wipers or pressers for affixing the label are also described. The labels are held in a holder 3 and the lowermost is removed by the suction device 16, which consists of a tube connected to a cylinder 12 moving over a fixed piston 13. The labels are retained by a weighted plate y, and as the suction device comes in contact with the lowest label a stop 24 attached to the carrier 11 carrying the suction device strikes against a spring-controlled rod 25 and causes it to grip a stem attached to the plate y. As the carrier 11 descends, a Geneva-cross 18 attached to the tube 16 strikes against fixed pins 20, so as to turn through two right angles in succession and present the label, first to a gumming-roller 28 and then to the article to be labelled. If the later is a bottle or the like the label may be affixed by wipers 23 carried on oppositely-rotating shafts 21. Fig. 5 shows a modification in which wipers 40 are carried on arms 41 carried on a reciprocating rod 43. The arms 41 are drawn together by a spring 44 and connected by toggle-levers 42 which strike against stops 46, 47 so as to allow the wipers to separate and pass the bottle as they rise and approach each other and come into action as they descend. For affixing labels to flat articles the suctionpipe slides under the action of a spring 33, Fig. 3, in an arm 30 attached to the Geneva-cross 18, which also carries a flat presser plate 34.

Filed: 1928-10-27
Abstract: 299,709. Aina, A., (Assignee of Caresana, G.). Oct. 29, 1927, [Convention date]. Spray carburettors.-The nozzle is fed directly from the fuel tank without the interposition of a float chamber, and the discharge therefrom is controlled by a valve actuated from a throttle valve which controls the inlet of air to and outlet of mixture from the mixing chamber. In the body 1 is formed a mixing chamber 2 having an air inlet 3 and a mixture outlet 4 controlled by ports 19, 20 in a rotatable tubular throttle valve 18. Coaxial with the throttle is a nozzle 9 supplied with fuel under pressure from an inlet 6 through a duct 5, filter 7, perforated tube 8 and duct 10. The nozzle outlet is controlled by a valve 11 loaded by a spring 12 and having an extension 14 projecting beyond the outlet. A casing 15 slides over the top of the nozzle and is forced bv a spring 17 against a, pin 25 mounted adjustably in the throttle valve. The casing has ported gauze-covered walls and, at its base, air inlets 28 to effect a preliminary mixing. The throttle spindle 21 is screw-threaded through the cover at. 22 and carries an actuating lever 24 locked by a nut 27, a second nut 26 serving to lock the pin 15. As the throttle is rotated towards its open position, it moves axially, and the pin 25 depresses the casing 15 which, in turn, forces down the needle valve and increases the fuel supply. In lieu of the throttle spindle being screwed, a cam may be employed between the throttle and its casing, or the pin 25 may be engaged by helical means with the throttle which would then merely rotate.

Abstract: 1,212,924. Injection moulding. F. STUBBE. 1 July, 1968 [5 July, 1967], No. 31321/68. Heading B5A. An injection moulding machine in which the injection nozzle 10 is moved into engagement with the mould 6 by a pressure actuated feed unit 16 includes a control device 14 to actuate the injection step when pressure within the feed unit builds up to a desired value. A rotary table 2 carries mould units 3, each comprising moulds clamped between plates 4, 5, which moulds are brought, in turn, into alignment with an injection unit 1 which is urged towards the moulds by a pair of hydraulic feed units 16. The cylinders 19, Fig. 2, of the units are stationary, and their piston-rods act through springs 13 to engage a projection 18 on the injection unit to force its nozzle against a feed bush 8 of the mould. A switch 14 is secured to the injection unit adjacent the end of one of the rods 17 so that when pressure in that feed unit builds up due to the engagement of the nozzle and mould, the force of the spring 13 is overcome and the switch is actuated by the end of the rod to initiate the injection step. The pressure necessary to effect this operation is varied by adjusting the position of a cap nut 15 on the rod end. Alternatively the spacing z may be varied. The injection step may alternatively be triggered by a pressure switch connected with the pressure chamber of the hydraulic feed unit.

Abstract: 487,574. Safety razors. ECKBO, E. J., and FOUGNER, N. K. Nov. 15, 1937, No. 31368. Convention date, Sept. 1. Addition to 419,030. [Class 30] In order to facilitate insertion and removal of blade spools in razors made according to the parent Specification, the guard 5 and its stem 8 are made detachable from the tubular spindle 6 by which the guard is moved up to clamp the ribbon blade. The stem is in the form of a split pin and fits frictiontight in the spindle. It is pressed up by a spring-pressed plunger 9. The spindle has an external thread in engagement with the body and is reciprocated by turning a knob 7 at its lower end. In order to prevent excessive stress being put on the blade strip during winding, a pivoted lever 15 is caused to bear on a shoulder of the winding-on spool 13 after the manner of a brake when the spindle 6 is raised. A ratchet detent prevents the bladereceiving spool 13 from backward turning. In a modification, Fig. 6, a projection 18 on the guard 5 engages a piston head 20, so that by depressing the latter against the action of a spring 21, the guard can be removed as shown.
