Patent GB-964272-A (GB)
Title: Textile fabrics and process for their production
IPC: D03D15/00
Filed: 1961-04-21
Abstract: 964, 272. Woven fabrics; fibrous fabrics; yarns and threads. DOW CHEMICAL CO. April 21, 1961 [April 27, 1960], No. 14597/61. Headings D1K, D1R and D1W. A fabric made entirely or partly from thermoplastic microtapes folded or rolled on themselves so as to have a labyrinthian cross-section is calendered or embossed at a temperature and pressure that does not cause plastic flow. The tapes may be folded zig-zag or as shown in Fig. 4, or may be rolled as shown in Fig. 5, or the two edges of the tape may be folded or rolled as shown in Fig. 4 or 5; they may be laminates of identical or different layers, or may consist of separate strips plaited together; they may be individually twisted, or may be plied together. The tapes are preferably microporous and may be a copolymer of vinylidene chloride with acrylonitrile or a lower alkyl acrylate. The pressure brings the constituent layers of the tape into contact, thereby making the tape thin and transparent over the whole area of the fabric or in a pattern; in pigmented tapes, the colour becomes more intense. The compression also reduces the permeability of the fabric to liquids and gases. The fabric may be woven, or may be made by bonding together randomly disposed filaments, or bonding together continuous filaments running in one direction with randomly disposed cut filaments. In an example, a fabric woven from a warp of natural microtapes and a weft of pigmented microtapes is embossed to produce a pattern of solid weft colour in the compressed areas, the warp remaining opaque in the uncompressed areas. A similar effect is obtained using cotton or nylon as warp or weft with microtapes in the other direction.

Filed: 1944-08-03
Abstract: 577,375. Safety razors. HEIDE, H. C. (Gillette Safety Razor Co.). Aug. 3, 1944, No. 14828. [Class 30] In a safety razor in which the blade is clamped between cap and guard members having co-operating projections and recesses, grooves or apertures to position them relatively to one another, these projections and recesses &c. are so arranged that in the final clamping operation, the slight angular movement of one member relatively to the other due to clearance between the projections and recesses &c., brings the edges of the members into parallelism. As shown, a rib 16 formed on the cap member 15 and parallel to its edges co-operates with a groove 13 formed in the guard 10 at a slight inclination to the edges thereof. The handle screws on to a threaded stud projecting from the cap 15 through the guard 10 and upon the final part of the clamping movement, the cap 15 is twisted slightly due to the clearance between the rib 16 and groove 15 and this clearance and the angular position of the groove are such that when the rib 16 engages the opposite sides of the groove as shown, the edges of the cap and guard are parallel.

Title: Improvements in and relating to bottle cleaning machines
IPC: B08B9/30
Filed: 1964-04-10
Abstract: 997,534. Bottle washing machines: conveyers. SEITZ-WERKE G.m.b.H. April 10, 1964 [April 13, 1963]. No. 14844/64. Headings B8A and B8T. In a bottle cleaning machine the bottles in carriers are conveyed continuously through an immersion station and intermittently through a spraying station. Bottles are loaded into carriers 11 formed from several adjacent individual cells 12 at a loading station 14 and transmitted to a preliminary spraying station 15 by a rotatable conveyer 16. A further rotatable conveyer 17 then sets the carriers upright and carries them to an inclined conveyer 18 which conveys them to a pair of rotating conveyer screws located within an immersion bath. Guide members 22 located on studs 21 on the carriers engage in the threads 20 of the screws, the studs 21 resting on a pair of runners 32. At the end of the immersion station the pitch of the. screws is such that it accelerates the advance of the carriers until their velocity corresponds to the speed of a revolving conveyer 23 which removes the bottle carriers to a conveyer track 25 passing through a spraying station. The carriers are supported on parallel rails of the track 25 by further studs 26, and push rods 25 advance the carriers intermittently, the rods 28 engaging the studs 26. Centering combs 30 connected to the rods 28 locate the bottle necks above spray tubes. Alternatively, the carriers may be moved intermittently by pull ratchets or endless chains. After being sprayed by lye, hot water, cold water and fresh water, the conveyer 16 receives the carriers and transports them to a delivery point where the clean bottles are removed.

Abstract: 915,585. Endless conveyers. METAL BOX CO. Ltd. March 7, 1961 [April 29, 1960], No. 15214/60. Class 78 (1). Cans 2 moving along a conveyer 1 engage and thereby rotate a plate 5 which carries a series of electromagnets 9. If the latter are energized, the can in engagement with the plate 5 will be caused to adhere to it and will be deflected into a reject path 22. The energization of the magnets 9 may be initiated from a sensing head 18 which may be arranged to detect the presence of the metal bottom of a can, or alternatively the absence of the same. In a modification (Fig. 4, not shown) the sensing head is adapted to transmit a signal in respect of every can passing on the conveyer. A device is then included in the circuitry which causes only alternate signals from the head 18 to be transmitted to the contacts 9. Thus alternate cans pass into the path 22 while remaining cans continue on the conveyer 1. The electromagnets 9 are connected electrically to energizing amplifiers 20, 21, by means of a commutator 10 (shown apart from the plate 5 in Fig. 1 for clearness). Two sets of contacts 11, 12 are provided on the commutator 10 so that two successive electromagnets 9 may be energized in overlapping relation (for example when two successive cans are to be removed from the conveyer). Synchronizing contacts 16 are also carried by the commutator 10. Alternative synchronization may be effected by means of a photo-electric cell or a coil metal sensing device.
