Title: Improvements in or relating to paper laminates
Inventor: ARNDT HERMAN ALBERT HANS RUDOL
Filed: 1965-04-08
Abstract: 1,079,557. Laminating. J. A. DEKKER. Dec. 7, 1965 [April 8, 1965], No. 14929/65. Heading B5N. [Also in Division B8] A process for preparing a paper laminate comprises sandwiching particles or granules of a synthetic plastics material capable of flowing under heat and pressure between two sheets of paper, and applying heat and pressure to the sandwich so that the plastics material flows, and the particles or granules form a coherent layer between the paper sheets, which layer is self-adhering to the paper sheets, at least one surface of one of the paper sheets being treated so as to cause the particles or granules to adhere thereto prior to forming the sand. wich. In apparatus for performing the process a sheet of paper 13 is unwound from a roll 11, passes between nip rollers 14, 15 and is treated by wetting one of its faces with water applied by a grooved or serrated roller 16. The sheet then passes wetted face uppermost beneath a hopper 22 from which particles or granules 23 are deposited on it, and is fed between rollers 29, 30 together with a second sheet of paper 26 from a roll 24 to form a sandwich. The sandwich is fed between heated pressure plates 31, 32 which are operated intermittently to form the laminate by causing the plastics particles or granules to flow into a coherent layer. If it is desired to form a corrugated laminate the surfaces of the pressure plates 31, 32 are made undulatory. The plastics material used may be polyethylene or polyvinyl chloride but is preferably polystyrene in which case the operating temperature of the pressure plates is 105-130 C., preferably 108 C., and the operating pressure is 0À1 to 0À5 kilograms/cm.<SP>2</SP>. The pressure plates may be heated by steam under pressure, electricity, or by gas flames. In a modification the sheet 13 is treated on both surfaces by drawing it through a water bath. The pressure plates 31, 32 may be replaced by heated rollers to give continuous operation, and the sandwich may be heated by high-frequency heating before being pressed. In order to prevent particles or granules from dropping off the sheet 13 it is made slightly narrower than the sheet 26, the edges of this latter sheet then being bent downwardly perpendicular to the general plane of the sheet by a framework placed across the sheet. To ensure the desired density of particles or granules being supplied from the hopper it is provided with an adjustable baffle. The completed paper laminate can be used as wrapping material, or as ceiling or wall board, or as an insulating panel.

Filed: 1927-06-08
Abstract: 296,487. Marks, E. C. R., (Pratt & Whitney Co.). June 8, 1927. Round holes, enlarging and trueing.-A machine for grinding cylinders internally consists of a grinding- wheel rotating on a stationary axis, and a work-table having a planetary motion to move the work in contact with the disc while the direction of any line of the table does not change, means also being provided for adjusting the radius of movement of the table for applying feed or for removal &c. of the work. The grinding-wheel is shown carried by a vertical spindle 22, adjustable vertically on a drilling- machine frame 10 and driven from a shaft 25 or otherwise. The work W is mounted on a table 32 movable on a hollow base 31 in which is a hollow shaft 30 driven by worm-gearing from the shaft 25. Rotatable within the shaft 30 is a shaft 35 driven by the shaft 30 through an epicyclic bevel train 36, 37, 39, 43, 44, 45 mounted in a fixed casing 40. The gear 37 is connected to a gear 48 in mesh with a gear 49 rotatable, through gearing 51, by a handle 53, and whilst the gear 48 is stationary, the shafts 30, 35 rotate in unison; rotation of the gear 48 in either direction, however, causes a corresponding change in the speed of rotation of the shaft 35. The shaft 30 has a head 33 carrying on guideways 61 a slide 59, to which is secured a nut 57a engaged by a screw 57, which is geared to the shaft 35 by bevel gears 55<a>, 56<a>; the slide also carries in a ball bearing 62 a stud 63 engaging and moving the table 32. Whilst the shafts 30, 35 rotate in unison, there is no relative movement between the gears 55a, 56<a>, but upon rotation of the gear 48 a relative motion of the gears occurs and the screw 57 is rotated, the position of the stud 63 thus being changed. An index 54, 56 is fitted to show the change of radius of movement of the table produced by rotation of the gear 48. The table 32, during its motion, is maintained parallel to itself by links 71 pivoted by studs 70 to the base 31, links 73 pivoted by studs 72 to the table 32, and a link 75, studs 74 connecting the pairs of links 71, 73 to the link 75.

Title: New resinous compositions
IPC: C09F1/00
Filed: 1950-06-19
Abstract: Thermoplastic or thermosetting products suitable for use in brake linings and like antifriction materials are obtained by compounding together a solid pinewood resin and a liquid anacardic material. Solid pinewood resins are the residues obtained in distilling a solvent extract of pinewood to remove solvents and rosin and are known under the trade name "Vinsol" (Registered Trade Mark).  Liquid anacardic materials comprise cashew nut shell liquid and its liquid polymers, and distillates and residues therefrom, e.g. as described in Specifications 481,960, 599,198, 625,493.  The compounding is carried out by heating the mixture at temperatures in the range 200-600 DEG  F. in the presence or absence of an acid catalyst.  The materials may be separately reacted with aldehydes before admixture or the compounded mixture may be so treated.  The mixture may also be halogenated or sulphurized. The uncured products may be mixed with rubber, chloroprene polymers, or butadiene/styrene/acrylonitrile copolymers and with the addition of asbestos and hexamethylene tetramine moulded to give brake linings.  In examples: (1) 100 parts pinewood resin are reacted with furfuraldehyde the product is mixed with 25 parts cashew nut shell liquid and the mixture reacted with formaldehyde in the presence of diethyl sulphate to give a dry infusible mass; (2) as in (1) employing paraform and lime for the final reaction; (3) cardanol is used instead of the nutshell liquid; (5) and (6) thermoplastic products are obtained by increasing the proportions of the cashew nut shell oil constituent up to 75 per cent.  In Examples 7-11 the cashew nut shell liquid is reacted with formaldehyde in presence of ammonia and like alkaline catalysts prior to admixture with the pinewood resin.

Abstract: 797,468. Centrifugal pumps. ALLISCHALMERS MANUFACTURING CO. May 16, 1956, No. 15317/56. Class 110 (1). [Also is Groups XXXIV and XXXV] The pump impeller 47, Fig. 1, and the rotor 46 of the driving motor are carried by a hollow shaft 44 which surrounds, with clearance, a stationary member 31. Member 31 is carried at one end in a bore 9 in a cover-plate 5 and at the other end in a bore 34 in the end of a fluidtight shroud 22 which isolates the motor stator 57 from the pumped fluid. A pin 37 extends into a groove in the member 31 to fix it. Some of the pumped fluid passes by way of an annular channel 21 and radial passages 12 to the bore 9 and thence through holes 43 in the hollow member 31 to the spaces between the shaft 44 and flat faces 39, Figs. 1 and 4, formed on the member 31. The fluid maintains the shaft 44 coaxial with, but spaced from, the member 31. The fluid leaking from the spaces returns to the impeller 47 through holes 49. The flow of fluid cools the rotor 46. Some of the pumped fluid fills annular grooves 11, 23 to prevent axial movement of the shaft 44. The rotor 46 has a fluid-tight casing 48. The stator 57 may be cooled by air, as from a blower, introduced at 63 and expelled at 64. Alternatively, cooling water may be passed through hollow stator conductors.

Abstract: 421,276. Coin-freed article-delivery apparatus. DEAN, H., Mount Street Works, Mount Street, Nottinghamshire. June 8, 1933, No. 16413. [Class 27] A semi - rotary vending - machine having article discharge means such as described in Specification 368,819 comprises several columns of articles each having a coin-operated articledelivery means, all being controlled by one locking- piece and being operable by one lever or handle either individually or all together according to the number of coins inserted in separate coinslots. Recessed ejecting seatings J, J<1>, J<2>, Fig. 1, one for each column, are connected by plates H, H<1>, H<2> to coin cups G, G<1>, G<2> loosely mounted on a hand operated spindle E between the end walls of a hollow halfcylinder F, Fig. 3, which is secured to the spindle and is provided with three sets of prongs F<5> for engaging the coins inserted through the different slots to the coin cups. On a spindle A<2> is mounted a locking pawl P having a bar P<1> extending laterally into the path of shields or coin-guides C, C', C<2>, also mounted on the spindle A<2>, the pawl P normally engaging an abutment F<3> on one wall of the cylinder F to prevent rotation of the spindle E in the absence of coins. Each of the shields C, C<1>, C<2>, has a portion L<2>, Fig. 6, engaging an abutment M on its corresponding coin cup, and a rounded nose L which rides on the periphery of a coin when this is pressed forward by its prong F<5> on rotation of the spindle E. The coin thus raises the shield C which releases the pawl P by acting on the bar P<1> and also releases the coin cup. The further rotation of the spindle E, which is now possible, presses the coin against a shoulder K on the coin cup and rotates this cup together with its corresponding ejecting seating to deliver an article. If more than one coin is required to get delivery from a column, the nose L of the corresponding shield C-C<2> is slotted so that the last inserted coin only is effective to raise the shield. A pawl R engaging a ratchet F<1> on the cylinder F provides a fullstroke device. An abutment F<2> on the cylinder F engages an arm S, Fig. 12, and stresses a spring T which returns the parts to normal position after discharge of the coins.
