Title: Device for applying sealing strips to paper containers
IPC: B65B51/04
Filed: 1937-12-03
Abstract: 506,760. Closing cartons; bending metals. JAGENBERG, G. MEYER. Dec. 3, 1937, No. 33523. [Class 94 (i)] [Also in Group XXII] In machines for applying sealing strips to the collapsed ends of containers, a ram pushes in one stroke, a strip of metal through a die to bend it into channel shape and into apparatus for feeding the bent strip to the collapsed end of a container. A web 2, Fig. 2, of metal strip is pulled from a roll past a tensioning roller by a gripping jaw 7 on an oscillating lever 6. The lever is oscillated by a crank-pin 16 in a block 18 moving in a slot 6a in the lever, and the throw may be adjusted by rotating the crank-pin on an eccentric mounting 15. The forward end of the strip enters slots 23, 24 in a die 22, Fig. 4, and during the return of the lever 6, a length is severed from the web by knives 19, 20. The severed length is thrust out of the die by a ram 25, being thereby bent into channel shape, and is received in a pocket 27a of a carrier wheel 27. The openings of the pockets are contracted to prevent the strips from falling out while the wheel rotates and carries them to the applying position. The cartons P with their top edges collapsed, are fed beneath the carrier wheel by plates 32 projecting from a conveyer chain 31. A slide 29, Fig. 6, is arranged above the path of the conveyers and carries a guide 30 which controls the top of the carton and moves with it, but at a slower speed until the carton is completely within the lowermost slot of the carrier wheel and the guide is about to enter the slot. The speed of the guide is now accelerated up to that of the container, arid it engages the end of the metal strip, and pushes it out of the slot, in position on the carton, into the grip of rollers s, t, a, b, arranged as described in Specification 445,253, for clamping the strip.
Patent GB-1068773-A (GB)
Title: Pile fabrics
IPC: D04H11/00
Filed: 1964-08-17
Abstract: A pile fabric comprises short synthetic fibres electrostatically flocked on to an adhesive layer, at least 25% of the fibres having a latent crimp which is developed after flocking to cause their upper ends to bend and become entangled with adjacent fibres.  The crimpable fibres may be bicomponent acrylic fibres consisting of acrylonitrile and a copolymer of acrylonitrile with vinyl acetate or sodium styrene sulphonate extruded side by side.ALSO:A pile fabric comprises a plurality of short synthetic organic polymeric fibres individually and randomly attached in generally upstanding relationship to an adhesive layer, the pile formed by the fibres comprising a support portion occupied by the lower 50% sections of the extruded length of the fibres and an upper portion occupied by the remaining sections of the fibres, the fibre section in the support portion being essentially spaced apart, free from crimp, and substantially perpendicularly aligned with respect to the adhesive layer, and the fibre sections in the upper portion having an average crimp frequency (defined) of 1 to 8 crimps per inch thereby creating a pile surface having a random and a multidirectional array of fibre sections and fibre-to-fibre entanglements.  The fibres may be 0.01 to 0.5 inch long.  The fibres may consist of at least two longitudinally extending components of different synthetic organic polymers e.g. acrylonitrile polymers or polyesters.  The pile density in the upper portion may be at least 1-5 times that in the support section.  The ratio of the extended fibre length to the effective length of the crimped fibre may be 1.1 to 1.7.  The ratio of the radius of curvature of the crimped section of the fibre to the length of the uncrimped portion of the fibre when relaxed may be from 0.95 to 0.15. A pile fabric may be produced by depositing a layer of upstanding straight synthetic organic polymeric flock fibres on a backing material coated with an adhesive, at least 25% of the fibres being latently crimpable and remaining straight during the deposition, and treating the resultant fabric to develop the latent crimp of the fibres.  The fibres, which may be from 0.01 to 0.5 inch long, may have been treated to prevent their crimping during the deposition. The fibres may have been treated with a separating agent, or an antistatic agent, examples of which are given.  The fibres may have been prepared by holding long fibres tautly in the longitudinal direction while wetting them with a separating agent, drying the treated fibres while they are still in the taut condition and cutting short fibres therefrom.  The fibres may consist of at least two longitudinally extending components of different synthetic organic polymers e.g. acrylonitrile polymers or polyesters.  The fibres are deposited on the backing material by use of an electrostatic field, or a beater device.  Crimps may be developed in the fibres by subjecting them to hot wet processing conditions.  Conditions may be such as to produce the pile fabric described above.  Examples of fibres and backing materials are given.

Abstract: 1,162,801. Transducers; reflectors. WESTINGHOUSE ELECTRIC CORP. 28 July, 1966 [13 Sept., 1965], No. 33883/66. Headings H4J and H4X. In a transducer comprising an oscillatory driving element 20 (Fig. 5), two reflecting surfaces meet at a right angle. The first reflecting surface faces the rear surface of the element 20 at an angle and the second reflecting surface projects entirely outside the driving element at the free end. The rear wave from the element 20 strikes the two reflecting surfaces in sequence and is propagated after successive reflections beyond the element 20 and past the free end. The second reflecting surface is convex. Preferably the phase front of the reflected wave is in the same plane as the front emitted wave. However, the reflected phase front may lead or lag the front emitted wave. The reflecting surfaces are preferably surfaces of revolution and the element is cylindrical. Four further surfaces of revolution may be provided, all conical and all co-operating with an element 20<SP>1</SP>. One valley may be shallower than the other to provide a leading phase front #/2. Fig. 3 shows a driving element equal to or less than #/4 at the operating frequency and located a distance x above the first reflecting surface. In Fig. 4 the first reflecting surface is less than 45 degrees to the vertical. The second reflecting surface is so curved that the #/2 reflected wave front extends lower than that of Fig. 3.

Abstract: 1,086,190. Magnetic tests. E.O. SCHONSTEDT. Aug. 3, 1966 [Jan. 12, 1966], No. 34780/66. Heading G1N. The invention relates to developing a misalignment correction signal for a magnetic gradiometer of the kind employing two flugate field sensors mounted with their axes substantially parallel and arranged to produce ideally equal and opposite outputs in a uniform field, but actually giving a small resultant signal due to misalignment. According to the invention, two further field sensors are mounted with their axes mutually perpendicular to one another and to the gradiometer sensors. A proportion of the signals from these further sensors is applied to nullify the error signal from the gradiometer in a uniform field. Alternatively D.C. correction signals may be applied to bias windings on the gradiometer sensors, Fig. 5 (not shown). A mathematical explanation is given.
