Class 81(1) A method for opening ampoules prior to filling comprises spinning the ampoule about its longitudinal axis at say 3000 r.p.m., playing a fine flame jet on the stem and automatically separating the ampoule body from the bulb by the action of tensioning means when the stem softens. As shown, pinion 29 is operated to displace bearings 11, 12 towards each other against the action of springs 21, 22 causing member 9, mounted on stationary rod 10 having a sliding fit in an axial bore in shaft 3 to open jaws 5, 6 of chucks 1, 2 mounted on shafts 3, 4 against the action of spring 7. Ampoule 25 is inserted in the jaws and gripped by further operation of the pinion prior to the rotation of the chucks. The cutting flame 37 which may be displaced tangentially to the axis of rotation by means of movable levers .35 attached to gas supply tube 36 softens the stem of the ampoule, the chucks are synchronously drawn apart by the action of springs 21, 22 and the two portions of stem are separated. The jaws are opened by the engagement of member 9 with projection 8A to discharge the ampoule body and bulb. The speed of rotation of the ampoule is sufficient to overcome, by centrifugal action, the tendency. of the softened stem walls to fall in. Specification 740,011 [Group XXIII] is referred to.

Title: Improvements in flushing-valves
IPC: E03D3/06
Filed: 1927-09-07
Abstract: 281,211. BrodÚn, E. E. T. Sept. 7, 1927. Valves controlled by pilot or relay valves.- In a flushing valve of the diaphragm - actuated type set in operation by a push-actuated tilting auxiliary valve, the stem 11 of the auxiliary valve 9 is fitted with a sliding tube extension 10 and is adjustable by screwing in the valve head 9 so as to vary the length of the stem in relation to the push 12, 13 and thereby regulate the duration of the flushing. The diaphragm 1 is formed with a concentric corrugation to obtain a longer stroke and to avoid the risk of the diaphragm being held in an upper dead position. When the push 12, 13 is actuated the auxiliary valve is tilted open to release the fluid pressure above the diaphragm whereupon the inlet pressure at 5 opens the main valve 8. The lower end 1( of the stem, after the predetermined rise, leaves the push and tilting ceases, whereupon the auxiliary valve closes down and the main valve closes to stop the flushing. This closing action is not interfered with even though the push 12, 13 is held in since the sliding extension 10 of the stem 11, on contacting with the pushrod, would still allow the auxiliary valve to close. Subsequent release of the push 12, 13 would allow the extension 10 to slide down into position for the next flushing operation.

Abstract: 1,218,948. Skin packaging apparatus. EASTMAN KODAK CO. 17 May, 1968 [18 May, 1967], No. 23530/68. Heading B8C. A platen for supporting a porous substrate to which articles are secured by drawing down over them a heated film by using a pressure differential, includes means to apply different pressures at different positions on the substrate so that pressure is higher in the vicinity of the articles. This is intended to prevent distortion or damage to the film portions covering the articles. In one arrangement, Fig. 3, the surface of the platen is covered by an air pervious screen 30 beneath which projections are formed by slotting as at 32 longitudinally and transversely. Holes 42, 44 communicate with the atmosphere and vacuum respectively. A removable gasket 46 fits in the slots beneath the position of each article on the substrate forming areas in communication with the atmosphere through apertures 42. In another form, Fig. 4, gaskets 70 are placed on a plate 62 having holes 66, 68 communicating respectively with two cavities 50, 52, the former being open to atmosphere and the latter having a vacuum connection. Each cavity contains expanded metal baffles 54, 56 to even out air flow. A perforated sheet 30<SP>1</SP> covers the gaskets and supports the substrate. In a further embodiment, Fig. 5 (not shown), a series of chambers beneath the perforated sheet are joined by pipes to each other and to atmosphere while the spaces between them are connected to vacuum. The complete packaging apparatus may comprise an extrusion head travelling over the platen to drape the warm film over the objects and substrate, Fig. 1 (not shown).

Abstract: The process consists in generating neighbouring gas jets (b, c, d, e, etc.) adjacent to a convex guiding surface (14), in diverting the jets and the streams which they induce by flow and adherence along the guiding surface and in bringing laces of ductile substance (s) into the streams induced by the jets in zones situated between the latter on the convex surface. In a second stage each jet enters a main gas stream (B) forming a zone of interaction and entraining the partially drawn fibre therein; the latter is then subjected to additional drawing in the interaction zone.

Abstract: 1,083,249. Feeding tobacco. HAUNIWERKE KORBER & CO. KOMM.-GES. May 31, 1966 [June 2, 1965], No. 24189/66. Heading A2C. A method of building up a tobacco stream, the height of which increases progressively and which is held together by air flowing transversely to the height of the stream is characterized in that the air pressure on the tobacco stream in the direction of the air current increases with progressive increase in the height of the tobacco stream. Tobacco is showered on to an air pervious belt 24 in a U-duct 22 from a tobacco distributer 4 to form a tobacco stream 100. The stream is then carried on a grooved suction wheel 8 to rod-forming apparatus 2. The belt 24 is guided by rollers over a suction chamber 32 which is provided with an auxiliary air flap 35 to reduce suction when stopping and starting the machine. The flap may be actuated automatically, Figs. 9 and 10 (not shown). The duct 22 has a bottom strip (38), Fig. 2 (not shown), over which runs the belt 24, provided with perforations through which suction is applied from the chamber 32. The perforations (80-90), Fig. 3 (not shown), increase in size over the width of the distributer 4 in the direction of the travel of the belt 24 so that the layer of tobacco furthest from the belt 24 tends to be subjected to a constant amount of suction. Beyond the distributer 4 the perforations in the strip (38) are of constant size.
