Title: Improvements in or relating to feeding means for labelling machines
IPC: B65C9/08
Filed: 1960-04-06
Abstract: 947,390. Sheet separators. H. KRONSEDER. April 6, 1960, No. 12242/60. Heading B6B. [Also in Division B8] In apparatus for labelling bottles (see Division B8) including a revolving cylinder a for applying the label, the cylinder carries a suction nozzle b which can be protracted from the cylinder to pick up a label from holding means and then withdrawn again, and means are provided for applying a backward angular movement relative to the cylinder to the nozzle as it is protracted and withdrawn, so that the speed of the nozzle relative to the holding means is reduced as the nozzle picks up the label. The cylinder a, Fig. 2, is rotatably mounted adjacent to a container e for labels. Suction nozzles b are mounted adjacent to slots in the periphery of the cylinder and move radially outwards as they come abreast of the container e during rotation of the cylinder so as to engage a label and withdraw it from the container. The nozzles b are pivoted to a bellcrank lever c pivoted within the cylinder a and carrying a cam-follower d which engages under spring-bias a cam f which does not rotate with the cylinder. A roller g carried by the nozzles b is spring-biased into engagement with a cam h secured to the cylinder a and rotatable therewith. The contour of the cam f is such that when the nozzles b are opposite to the stack of labels the bell-crank lever c is oscillated and the nozzles b thereby moved circumferentially in relation to the cylinder in the direction opposite to that of the rotation of the cylinder, the effect being that the nozzles perform no arcuate movement in relation to the stack while they are moved radially outwards from the cylinder under the influence of the cam h and follower g in order to engage a label in the stack. As the follower g reaches the right-hand end of the cam h the nozzles are retracted to a position wherein the outer ends thereof lie flush with the periphery of the cylinder. At a subsequent point in the rotation of the cylinder the nozzles are again projected to enable the label carried thereby to be gummed by gumming mechanism before being applied to a bottle. In a modification, Fig. 9, a container s for the labels is mounted so as to oscillate adjacent to the surface of a roller r to which gum is applied. At each oscillation of the container the roller r picks up a label # therefrom on its gum-carrying surface and carries the label round to a position wherein it is partially stripped from the roller by fingers u. At this point the label is engaged by the nozzles b of the cylinder a. In this form the effect of the cam f is to slow the arcuate movement of the nozzles until it corresponds with the peripheral speed of the roller r, which is a fraction of that of the cylinder a. Several containers s and rollers r may co-operate with a single cylinder a (Fig. 10, not shown).

Title: Improvements in or relating to cathode ray tubes employing electrostatic deflection
IPC: H03K6/02
Filed: 1946-04-24
Abstract: 621,958. Cathode-ray tubes. WHITE, E. L. C. April 24, 1946, No. 12324. [Class 39 (i)] [Also in Croup XL (c)] In a cathode-ray tube, a pair of electrostatic deflecting plates are split up into two parts 9, 10, Fig. 1, push-pull deflecting potentials are applied to the two parts 9, 10, and the mean potential of the pair of plates 10 is lowered relatively to the mean potential of the pair of plates 9 as a function of the deflection of the beam by the plates 9 so that, for any deflection of the beam, the beam as it emerges from the deflecting region passes through a potential substantially equal to the potential through which it passes as it enters the deflecting region so as to reduce beam defocusing. Preferably, the mean potential of the pair of plates 10 is lowered relatively to that of the plates 9 by an amount proportional to the square of the potential difference between the plates 10. The plates 9, 10 may be used for line or frame deflection. The deflecting plates may be divided into more than two pairs. In one circuit arrangement, Fig. 2, push-pull voltages are generated in the anode circuits of valves 11, 12 ; 13, 14 to be applied across the deflecting plates 9, 10. Part of the circuit input sawtooth waveform is integrated via a resistance 19 and condenser 20 and applied to the control electrode of a valve 16 so as to cause the current passed by the valve 16 to vary in a parabolic manner, and this causes corresponding changes in the potentials appearing in the anode circuits of the valves 13, 14, and hence in the potential difference across the plates 10. The resistance 19 may be connected to the control electrodes of the valves 11, 13 or to the anode of the valve 12. In another arrangement, Fig. 3, push-pull sawtooth voltages are set up in the anode circuits of valves 23, 24 and are applied to the plates 9 directly, and to the plates 10 via diodes 28, 29 which give non- linear attenuation and hence modify the potential difference between the plates 10 in the desired manner. Specification 622,002 is referred to.

Title: Process for producing film and sheet materials from thermo plastic materials
IPC: B29C48/30
Filed: 1972-03-17
Abstract: 1392841 Multiply films H PANNENBECKER and R PLATE 17 March 1972 [23 March 1971] 12548/72 Headings B5B and B5N A film of a thermoplastic material which has hot tack is made by extruding by the blown film process, at least two tubes, one outside the other, to produce an at least two ply tube comprising an inner ply of a tack-free thermoplastic material and an outer ply of a hot-tacky thermoplastic material, inflating and then flattening the at least two ply tube and slitting the tube at at least one edge. Preferably the split two- or multi-ply tube is wound into a roll in which hot-tacky and tack free layers alternate. In a modification, an at least three-ply tube is processed, the inner ply consisting of a tack-free material, the adjoining ply of a hot-tacky material, and the ply adjoining the hot-tacky material consisting either of a different hot-tacky thermoplastic material or of a tack-free material. The tack-free material may have a softening temperature 10 to 80 C., especially 10 to 40 C. below that of the hot-tacky material, which latter may have a softening temperature up to 300 C., especially up to 220 C. An outer layer of hot-tacky material may be covered by a further layer of a different hottacky material or of a tack-free material during extrusion. A blowing agent may be incorporated in the hot-tacky material prior to extrusion, and a foamable layer of thermoplastic material may be extruded as the outer layer of the tubing. Thus an inner ply of tack-free material may have superposed thereon a ply of non-foamed hot-tacky thermoplastic material and the latter may have superposed thereon a foaming layer which is undetachably bonded to the hot-tacky layer on which it is superposed. In addition to the production of multi-ply films in which plies of materials of differing softening temperatures are undetachably bonded together, in a modification the tack-free material does not substantially adhere to the hot-tacky material and the inner ply of tack-free material is a release ply which can be detached from the outer ply of hot-tacky material, the outer ply, after detachment from the inner ply, being a self-supported film. Specified tack-free materials include polyolefins, blends thereof with waxes, and a cellulose-triacetate-rosin composition. Specified hot-tacky materials include polyurethanes and copolyamides.

Title: An improved method and apparatus for the centrifugal treatment of liquid mixtures
IPC: B04B15/02
Filed: 1944-07-03
Abstract: 580,384. Centrifugal separators. AKTIEBOLAGET SEPARATOR. July 3, 1944, No. 12666. Convention date, July 8, 1943. [Class 23] In the centrifugal separation of a liquid mixture at a temperature higher than the boiling point of one, or both of the liquids, the lighter liquid is discharged from the bowl without coming into contact with the atmosphere and at, or higher than, the vapour pressure of the lighter liquid at its outlet temperature. The heavier component is discharged through an open outlet, and may previously be cooled by a water spray. The figure shows one arrangement in which the mixture is supplied through a hollow shaft 1, the lighter liquid being discharged through a pipe 9 sealed by packing 11. A chamber 16 contains cooling water supplied through spouts 24, the water passing along ducts 17 and mixing with the heavier liquid traversing ducts 8. This mixture passes through passages 18, 19 into a collecting chamber 20. The pressure of the cooling water when it engages the heavier liquid, prevents boiling or the formation of vapours. The lighter liquid is cooled after leaving an outlet 10.
