In Figs. 1 and 2 the fingers are moved to and from the surface 4 by a cranked rod 51 connected by a cord 55 to a lever 56 engaging a crank-pin 43 and are moved longitudinally from positions abutting a rear template 22 by the front edge of a slider 30 which engages lugs 46 of the fingers and is driven by arms 31, 32, the arm 31 having a slot engaged by the crank-pin 43 and being secured to a shaft 33 and the arm 32 being secured also to the shaft 33. The fingers 17 are slidable in passages in a support block 13 which passages may be parallel or divergent in order to stretch the material 5 sideways. Differential translatory movement of the material is provided by having a template 22 (here shown with a shallow V-shaped edge 21) and slider 30 with different profiles which may be interchangeable with others. In modifications the fingers may be moved to and from the surface 4, which may be a slippery surface or a movable carriage, by pivoting of the block 13 or may be mounted in individual guides (2) (Figs. 5, 6, not shown) which are pivotable about the support block (13C) by cam surfaces (76) (77) of the slider (30) to control sideways movement of the material 5.

Title: Improvements relating to parcels and to a method of forming them
Inventor: SMALLEY ARTHUR
IPC: B65B9/02
Filed: 1967-12-20
Abstract: 1,255,004. Packaging. FLOWRAP Ltd. 20 Dec., 1968 [20 Dec., 1967], No. 57939/67. Heading B8C. In a parcel marginal portions of a piece or pieces of heat sealable wrapping material are heat sealed together to form a wrapping around an article or articles, the or a marginal seal being interrupted to provide a slot, and a handle component projects through the slot to provide a carrying handle; the part of the component inside the wrapping has, parallel with the slot, an overall dimension in excess of the length of the slot so that the component cannot be withdrawn from the wrapping. In one form, Fig. 1, the handle component has a hand grip portion 1 in the form of a loop and two outwardly turned retaining portions 2. The loop 1 can have its maximum -dimension slightly greater than the length of the slot so that it: must be slightly elastically deformed before it can be passed through the slot. Alternatively the handle component can be a coat hanger. As described, the parcel is formed in a wrapping machine disclosed in Specification 1,541,165; in this machine there are two rolls R and R<SP>1</SP> of wrapping material, the free end margins of which are initially secured together so as to form a web which extends across a table T. The free end margins are secured in such a way that the above-mentioned slot is left intermediate the ends of the margins and the handle component is then engaged with the web from the left-hand side so that the handle portion projects from the right-hand side of the web. An article A or a group of articles is then fed into the machine in the direction of the arrow in Fig. 3a over table T and on to the platform P; this movement causes wrapping material to be drawn from the rolls so that the article or group of articles on the platform is enclosed in a fold of the wrapping material; upper sealing bars B which are heated, then move down to seal the layers of wrapping material together between themselves and the fixed bars B<SP>1</SP>; the layers are sealed together at adjacent transverse zones and at the same time a guillotine G moves upwardly between the adjacent zones so as to sever the wrapping layers to leave the article or group of articles wrapped in a sleeve and the free end margin of the wrapping materials sealed together to maintain the continuity of the web. The upper sealing bars then rise to their original positions and the parcel is removed to enable another article or group of articles to be wrapped. The machine can have sealing bars extending perpendicularly to the bars B<SP>1</SP> so that the margins of the end portions of the sleeve can also be sealed. To enable the slot to be formed the sealing bars to the left-hand side of the plane containing the guillotine G are interrupted so that there is an interrupted seal formed. A feeding conveyer can be substituted for the table T and the rolls R and R<SP>1</SP> can be driven, the conveyer drive and the roll drive being under the control of an operator.

Abstract: 1,255,169. Centrifugal pumps. NASH ENG. CO. Dec. 10, 1968 [July 12, 1968], No.58668/68. Heading F1C. A liquid-ring pump assembly has a drive-shaft 10 mounted in bearing 62, 64 coaxially supported in a hollow pedestal body 52 attached at one end via a rabbeted joint 56 to the pump housing 20. The diameter of bearing seat 70 is equal to or greater than that of the bearing seat 68. Thus the bearing seats 68, 70 and the jointing surface 56 can be machined from one end of the pedestal body during a single set-up thereof on a machine tool. Similarly, other parts of the assembly, e.g. the pump housing 20 and body 40, can each be arranged to be machined during a respective single set-up. The pedestal body may contain lubricant for the bearings. Shims may be placed at 58 between the pedestal body and the pump housing to axially adjust the pump housing 20 and body 40 relatively to the rotor 12. Moreover, a disc spring (not shown) may be placed between the rotor hub and a shoulder on the shaft to permit yieldable adjustment of the rotor along the shaft by rotation of nut 28, and thereby cause the rotor to move relatively to the conical portion of body 40. The joint between flanges 44, 48 may be of the rabbeted type. Shaft seal 34, 36 biases the rotor 12 away from pump housing wall 32.

Abstract: 1405650 Welding by fusion NATIONAL RESEARCH INSTITUTE FOR METALS 29 Dec 1972 60125/72 Heading B3R In consumable or non-consumable gasshielded arc welding, the arc from the end of the electrode is deflected by a stream of gas additional to the shielding gas, the direction of said stream being inclined to the electrode axis and intersecting said axis at the end of the electrode. The arc direction is determined by the stream/ electrode axis angle and the flow rate of the control gas stream. The arc may be oscillated by pulsing the control gas stream, and/or by changing intermittently the additional gas stream direction, a single pulsed stream effecting oscillation to one side, and two oppositely disposed, alternately phased, pulsed streams effecting oscillation to both sides, of the electrode axis. In Fig. 6, the arc in rotated, e.g. for welding a ring to a plate, by rotation of a control gas stream nozzle 5 which is ball-journalled on a shielding gas nozzle 1 and is motor-rotated via a flexible shaft 13 and gearing 11, 12. The shielding and control gas may be inert, e.g. argon; alternatively, the shielding gas may be CO 2 .
