Title: Improvements in or relating to wrapping machines
Inventor: LOVETT VERNON
IPC: B65B11/20
Filed: 1954-12-03
Abstract: 833,322. Wrapping-machines. PRECISION ENGINEERING Ltd., H. & B., [formerly PRECISION ENGINEERING & TOOLS CO. (WALFORD) Ltd., H. & B.]. March 1, 1956 [Dec. 3, 1954], No. 35153/54. Class 94(1). [Also in Groups VIII and XVI] A wrapping machine for enclosing rectangular objects, or groups of objects, in which the object or group is fed into jaws carrying the wrapper with it and thus causing the wrapper to cover its front, upper and lower sides, the jaws then moving relative to another folder to cause the wrapper to be folded on to the rear side, has tucking members mounted on the jaws for forming the front tucks. A web of wrapping material 21 is fed by rollers 35, 40 (see Group XVI) part cutter blades 59, 61 (see Group VIII) which cut off a wrapper and hold it suspended in the path of the object as it is fed to the jaws. The objects are fed from the base of a magazine, defined by guides 80, 81, by pusher elements 85 extending from a bar 74 oscillated by cam means. The jaws comprise members 121, 95 mounted independently, the jaw 95 being urged into gripping position by a spring 96. Pivoted on the members 121 are tucking devices 123, and as the wrapper and object enter the jaws they contact the devices to produce the tucks, Fig. 17. A member 86 presses the wrapper on to the upper wall of the object. The jaws now swing downwards enabling an element 124 to fold the wrapper over the rear side, and then advance towards a folding channel 128, Figs. 18, 19, to thrust the object into the channel before opening and receding. The upper wall of the channel completes the wrapper overlap which is heat sealed by an element 131, and rear tucking and the folding down of the top and bottom end folds is carried out by fixed folders 130, 132, 133, Fig. 8. The wrapped article is advanced through the channel by the following object, heaters 134 sealing the end folds. A feeler, Fig. 16 (not shown), is carried by the bar 74 at its rear end to contact the lower object in the magazine at the end of its forward travel. In the event of the magazine being empty, the machine stops.

Abstract: 416,915. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Willis, C. H.; 184, Prospect Avenue, Princeton, New Jersey, U.S.A.) Dec. 21, 1932, No. 36239. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 23, 1933]. [Class 38 (ii).] Valve converting apparatus for interconnecting a D.C. circuit 10 and a polyphase A.C. circuit 11 comprises a pair of valve converters, each comprising a polyphase network and a plurality of valves, and an interphase inductive winding interconnecting the converters with the D.C. circuit. In the arrangement shown in Fig. 1, each of the valve converters comprises a pair of three-phase networks 12<a>, 13<a>, 12b, 13<b>, with neutral points connected to commutating windings 14<a>, 14b shunted by condensers 15<a>, 15b, the mid-points of the commutating windings being connected to one side of the circuit 10 through the interphase inductive winding 22. The end terminals of the networks are connected to the other side of the circuit 10 through valves 16<a>-21<a> and 16<b>-21<b>, the valves being preferably of the vapour discharge type. In order to control the power factor conditions on the A.C. side, the grids of the valves are excited from the A.C. circuit 11 (or form an independent source of potential of the same frequency) through a phaseshifting transformer 25 and a grid transformer 26, 27. Means such as those described in Specification 390,184 are provided for giving a peaked wave form to the grid potentials. In another arrangement, Fig. 2, a six-phase network 29 with twelve symmetrically spaced terminals serves for both valve converters. One converter comprises commutating windings 30<a>, 32<a> and 40<a>-51<a>, and the other comprises commutating windings 30b, 32b and valves 40<b>-51<b>, connected as shown. The mid-points of the commutating windings are connected to the D.C. circuit 10 through interphase inductive windings 34, 37, which are shunted by series resonant circuits 35, 36 and 38, 39. In a modification, Fig. 3 (not shown), the resonant circuits are omitted, and the D.C. circuit is short-circuited through a reactance. In this arrangement, by displacing the grid potentials substantially 90‹ with respect to the anode potentials of the several valves, the apparatus draws a substantially wattless sinusoidal current from the A.C. circuit, and is effective to correct the power factor on the latter. Specifications 409,682, 409,713, and 411,145 also are referred to.
