Abstract: 1,036,594. Packaging-machines. K. KÍRBER. Aug. 1, 1963 [May 10, 1962; Feb. 6, 1963], Nos. 17999/62 and 4814/63. Heading B8C. Block-shaped articles P, Fig. 1, are fed singly from a magazine 4 along a track 2 by reciprocating drive members 3 and each receives a wrapper E from a pair of suction wheels 5, the wrapper being formed into a U-shape on the moving article and subsequently folded and sealed during the article's travel through a duct 8, guide track 13 and duct 12. The wrapper may be of heat-sealable cellulose foil or synthetic resin foil. Folding plates 76, Fig. 2, engage the leading edge of the wrapper projecting at either side of the article to form the leading end tucks; fingers 71, 72 carrying freely rotatable rollers 28, press in the tucks. Members 21, 22 hold the partially-wrapped article, the member 21 also folding down the upper rear flap of the wrapper; a folder bar 11 is then raised to fold the lower rear flap, the seam being tacked to form a tube by a heater bar 94 when the package is raised to the position P2. Sealing of the seam is effected at positions P3 and P4 by means of a reciprocable heating plate 9. A plunger 14 having folding elements 141 moves the package along the track 13 and folds the trailing end tucks. Apertures in the elements 141 receive members 341, 351 on blocks 34, 35 which prevent the lower end flaps from rising. Elements 181, Fig. 7, pass inside the blocks 34, 35 to fold up the lower end flaps, the package being subsequently raised on a plate 171 past spring members 264, 274 which fold down the upper end flaps. Heater fins 261-263 and 271-273 seal the end flaps as each package is raised successively against them. In a modification, Fig. 8 (not shown), counter-rollers are provided on the track 2.

Title: Improvements in spring mechanism
IPC: H01H3/30
Filed: 1937-06-30
Abstract: 496,414. Electrically-released switches. ENGLISH ELECTRIC CO., Ltd., and JOHNSON, W. L. June 30, 1937, No. 18204. [Class 38 (v)] A spring mechanism for closing switches which are too heavy to be closed sufficiently rapidly by direct manual operation, comprises a crank and a hand-lever adapted by repeated oscillatory movements to rotate the crank through ratchet and pawl or equivalent means to stress a spring more or less gradually, the ratchet or like means, while leaving the crank free to turn forwards, preventing it at all times from turning backwards, so that the crank must be moved past a dead-centre position and the spring fully stressed before the latter can be released to effect quick closure of the switch. Successive strokes of an operating handle 3, rotatable freely about crankshaft 2, cause a ratchet 1 to be rotated step-by-step by means of a pawl 4, and so turn a crank 2a from the dead-centre position shown to the opposite dead-centre, and, by means of lever 6 and a lever. 10, freely pivoted on a shaft 11 to which the switch-operating arm is connected, to stress a spring 8, whereupon the spring 8 is free to expand and close the switch by the engagement of an arm 10a pivoted on lever 10, engaging a projection 17a on a lever 17 fast on shaft 11. If desired, and as shown, the parts are retained just beyond the upper dead-centre by means of an arm 13 on the ratchet, or by the crank itself, engaging the roller 14 of a manually or automatically trippable lever. A detent 12 locks the ratchet during spring-stressing. For manual closure in an emergency, the hand-lever 19 is inserted into lever 17 and a projection 19a thereon engages an extension 10c of arm 10a to remove it from engagement with the projection 17a, so disengaging the spring 8 from the switch. Preferably the crank, spring, and lever system 6, 10 is repeated on the other side of the ratchet, and the impact of the springs is taken up by buffers 20 or dash-pots. The Specification states also that levers 6 could be pivotally or rigidly connected to the spring-mechanism, which would then reciprocate in fixed or oscillable spring- holders, and that the equivalent of the driven member 17 could be mounted on shaft 2 with the pawl 10a pivoted to the ratchet or one of the cranks.

Title: Process for the production of Polypropylene Films
IPC: B29C43/30
Filed: 1967-04-24
Abstract: 1,185,353. Polypropylene laminate. TOYO BOSEKI K.K. 24 April, 1967 [22 April, 1966], No. 18866/67. Heading B5N. A process for the production of a polypropylene film laminate having fine voids distributed throughout the whole laminate comprises superposing at least two polypropylene films each containing at least 65% by weight of isotactic polypropylene and each having a thickness of not more than 200 Á and subjecting the superposed film assembly to a necking stretch at a rate sufficient to cause the formation of voids while maintaining the temperature of at least one surface not greater than 45 C so that the superposed films adhere to each other during the necking stretch to form a unitary laminate. In one method of performing the process, polypropylene films F1, F2, F3 and F4, which are of crystalline polypropylene containing at least 65% by weight of isotactic polypropylene, and which may have been formed by extrusion and quenching, are fed via rollers 1, 2 where air is removed from between them, to a low speed roller 3 and cooling roller 5 and then between a high speed roller 4 and heating roller 6. The difference in the speeds of the rollers causes drawing of the films, the upper surface of which is cooled during drawing to below 45 C. by gas from a nozzle 7. After drawing the laminate formed may be heat treated by cooling rollers 8, 11 and heating rollers 9 before winding at 12. If desired the film F1 may be stripped from the laminate as shown, and this film may be heat treated by rollers 10. The films may include pigments, antioxidants, anti-static agents, stabilizers and plasticizers, and may be of the same or different colours. The voids formed in them give the laminate a pearly lustre. Preferably during drawing there is a temperature difference at the film faces of more than 5 C. and the draw ratio is 4 to 10: 1. The films may be stretched and then relaxed during the heat treatment and may also be stretched transversely e.g. by use of a stenter. The films may be of different thicknesses and there may be up to 10 of them. The laminates may be used for wrapping. They are thermally insulating and shock absorbent.

Abstract: 488,894. Laminated springs. TURRINELLI, G. July 12, 1937, No. 19325. [Class 108 (iii)] In order to regulate automatically the flexibility of a leaf-spring M, a member G is secured to the part to which one end of the spring is attached and has a face, adapted to engage the spring, so formed that its point of contact with the spring moves continuously away from the end of the spring to reduce the effective length and flexibility with increase in deflection of the spring. As shown, one end of the spring M is secured to a pin E slidable in a slotted shackle H pivoted at D, for example to a vehicle frame AB, the spring when loaded being adapted to bear against an increasing length of the curved member G fixed to the frame AB, thus decreasing the flexibility of the spring. In another construction one end of the spring is slidable in a slot in a pair of cranked shackles and the other end is hinged to a fixed pivot secured on similar but non-slotted shackles. In a further construction in which the spring is inverted relatively to that shown, each end of the spring is slidable in slotted cranked shackles pivoted to a vehicle wheel-supporting member on which the curved member G is mounted.
