Title: Improvements relating to compositions suitable for use in the manufacture of floor and wall coverings
Inventor: HOGG WILFRED HENRY
IPC: D06N3/14
Filed: 1957-04-03
Abstract: A composition suitable for use in the manufacture of floor and wall coverings comprises filler material together with a binder comprising (1) an oxidizable vegetable oil having in its molecule at least two hydrogen atoms replaceable by a metal and (2) a substantially non-crosslinked reaction product having in its molecule at least two isocyanate or isothiocyanate groups obtained from a diisocyanate or diisothiocyanate and a polyester, polyesteramide or polyglycol.  The binder may also contain vinyl resins (e.g. polyvinyl chloride, copolymers of vinyl chloride and vinylidene chloride, copolymers of vinyl chloride and vinyl acetate, polyvinyl acetate, and polyvinyl formal, polyvinyl butyral and other vinyl acetals), resins derived from pentaerythritol, phenol-aldehyde resins (e.g. xylenol-formaldehyde novolak resins) and natural resins (e.g. wood resin and dammar and other copal resins).  As plasticizers there may be added phosphate and phthalate esters (for polyvinyl chloride), glycollate and sulphonamide plasticizers (for polyvinyl acetals and nitrile rubbers (for phenolic resins).  The oxidizable vegetable oils include unoxidized oils, e.g. raw linseed oil, and partially oxidized oils, e.g. blown or gelled linseed or castor oil.  Tung oil, rape oil and dehydrated castor oil are also mentioned; animal oils may be used in addition to the vegetable oils.  Oils which are unreactive or insufficiently reactive can be made isocyanate group-reactive by heating with glycerol, glycol or other polyhydroxy compound or with an amine or hydroxyamine.  The prepolymer can be obtained from a simple diisocyanate or diisothiocyanate and a polyglycol and also trimethylolpropane and/or another aliphatic polyhydroxy compound.  In examples the prepolymers are prepared from propylene glycol polymer in one case containing trimethylolpropane and toluylene diisocyanate, stabilized with phthalyl or benzoyl chloride, or from a mixture of equal parts of oleic acid trimer and polypropylene ether diol. Other components of the mixture are in Example (1) gelled linseed oil, vinyl chloride-vinylidene chloride copolymer, dioctyl phthalate, tri-xylyl phosphate, lead carbonate, asbestos fibres, whiting and pigments.  Alternative ingredients in mentioned other examples are wood rosin, xylenol formaldehyde novolak resin, wood flour, pentaerythritol ester of rosin acid, cork flour, titanium dioxide, lead chromate.  The mixtures are blended in a mixer or roller mill, sheeted and heated to give linoleum-like material.

Title: Improvements in variable speed gear, particularly intended for diesel locomotives
IPC: F16H3/14
Filed: 1928-04-18
Abstract: 292,549. Krupp Akt.-Ges., F. June 22, 1927, [Convention date]. Variable - speed gearing suitable for Diesel locomotives comprises in each train a friction clutch, a claw clutch, and a ratchet clutch. Thus a gradual pickup of a higher speed is possible without disconnecting the lower speed. A gear a<1> fast on a driving- shaft A drives constantly gears b<1>, c<1> loose on countershafts B, C and adapted to be connected thereto alternatively by friction clutches b<3>, c<3>. Two gears h<1>, h<2> fast on driven shaft H mesh with four loose gears D, E and F, G on the shafts B, C, respectively. The gears D -- G are connected through ratchet clutches d<1> - - g<1> to claw clutch members d<2> - - g<2>, respectively. To bring in a higher speed, a feathered double clutch b<4> or c<4> is slid into engagement with the loose member such as g<2> and the friction clutch such as c<3> in the train is gradually applied. The friction clutches may be electromagnetic. A bevel clutch reversing gear is shown for driving a tail shaft M in either direction. Specifications 28760/04, 9604/10 and 137,783 are referred to.

Abstract: 652,474. Hoppers. MACHINES AUTOMATIQUES BARDET. April 27, 1948, No. 11501. Convention date, Oct. 20, 1947. [Class 78 (i)] A discharge gate for a hopper 1 (Figs. 1a and 2), comprises a movable element composed of a pair of side plates 9, 10 rigidly interconnecting a set 3-8 of flat horizontal plates having their ends adjacent to the hopper offset in stairway fashion and means to reciprocate the gate set at an angle to the horizontal. Figs. 1a and 2. The set of plates 3-8 held in the frame 9-10 is reciprocated quickly in the direction alpha and so cuts off and isolates a quantity of powder 2 from hopper 1 on each plate and these quantities are fed to the left between the plates to be discharged by the reciprocating movement. Fig. 3. Each of the plates 3-8 is formed with a lower ridge 3<1>-7<1> respectively so that the quantity cut off is less and so prevents jamming. Fig. 4a. Each of the plates is formed with a sloping surface by 131 so that the amount cut off is less and is reciprocated in the direction F of the slope. The surface of each of the set of gates may be corrugated and the material may be discharged into a weighing machine which automatically switches off the current when the required weight of material is fed thereon so that the reciprocating movement of the set of plates stops and the discharge of material for the hopper thus ceases.

Filed: 1971-06-11
Abstract: 1358831 Press brakes; metal sheet feeds RONEO VICKERS Ltd and R A DUFF 11 June 1971 [11 March 1970] 11610/70 Headings B3E and B3W [Also in Division B8] A metal sheet is moved from a position A to a position B on a table 55 by raising magnetic carrier 46 above the table until it engages and holds the sheet, moving the carrier to the position B, and lowering the carrier below the table so that the sheet engages the table and is stripped from the carrier. A sheet is fed to the station A where a hydraulically operated bar 61 roughly orientates the sheet. The carrier 46 is hydraulically lifted to hold the sheet above the table 55 and a truck 27 on which the carrier is mounted, is hydraulically moved to the position B. The carrier is then lowered to strip the sheet from the carrier after which pneumatically operated guide bars 79 and 80 are moved together to align the sheet. An hydraulic feed 113 is operated so that face 101 engages an edge of the sheet to push the latter between the bars 79 and 80 and further guide bars 83 and 84 until the sheet engages a back stop 21. Different back stops may be used by rotation of a shaft 17. A slide 124 having a pivoted support 131 is raised by a jack 134 to bring magnets 132 into engagement with the lower surface of the sheet A ram 14 of a press brake is then operated and when the ram bends the sheet, jacks 122 and 125 are operated to cause the support 131 to move simultaneously in vertical and horizontal directions and thus cause the support to follow the movement of the right hand portion, as seen in Fig. 3, of the sheet. When the bending is completed the jacks 122 and 125 are at the end of their stroke and so resist further movement of the sheet. The ram 14 is then lifted and the sheet moved out of the press by actuation of the jack 122. The support 131 is lowered by the jack 125 to lower the right hand side of the sheet into a horizontal position after which the slide 124 is lowered to disengage the magnets 132 from the sheet. A magnet is then extended from the face 101 of the feed 113 so as to engage the side of the sheet. The sheet is pulled back to the position B by retraction of the feed 113 and the magnet disengaged by retraction of the magnet behind the face 101. While the bending has been proceeding the truck 27 has been moved back so that the carrier 46 is again in position A. The cycle is then repeated but with the bent sheet being picked up by a second carrier 47 which is identical to the carrier 46. As the sheet is moved to a position C the carrier 47 is rotated either through 90 or 150 degrees by actuation of rotor 43 or rotors 43 and 45 respectively. At the position C the sheet is fed to the press brake, bent and retracted to position C in the same manner as at position B. Finally the bent sheet is moved to position D by a third carrier 48. The above feeding operation can be used to feed a metal sheet to a punching and notching press.
