Title: Improvements in and relating to processes of making mosaic or tesselation
IPC: B44C3/12
Filed: 1930-10-21
Abstract: Mosaic is made by casting the whole of the coloured elements to form a large slab or square in correct relative position in a partitioned mould, inverting the cast elements on to a board while maintaining their relative positions and then connecting the backs by an apertured sheet of linen, canvas, paper or the like treated with adhesive.  The slabs are transported to the place of use and then fixed to a foundation of mortar, the canvas &c. backing remaining in the mortar after fixing.  The moulds may either be filled with cements of different colours applied in succession through suitable stencils, or may be all filled with ordinary cement and various colouring powders applied afterwards through the stencils.  The moulded elements when inverted on to the board may be closed together slightly to diminish the spacing and enclosed in a skeleton frame. The canvas backing is laid on the elements and treated with adhesive applied through a stencil so that each element receives a quota of adhesive.

Apparatus suitable for applying particles of bronzing material to an article such as a web W of cigarette-paper comprises a light body member 1 mounted on two rubber bushes 9 so as to be vibrated on energization of a coil and armature device 22 and arranged to form a chamber 3 accommodating a rotatable drum 2 having a pile 4 of fibres, a guide roller 19 which guides the web W, to which adhesive has been applied by a roller 24, from the inlet 20 to the outlet 21, and a further pile of fibres 6 which are supported by and inclined to an arcuate part 5 of the chamber 3. Bronzing powder is fed from a reservoir 8 to the space between the surface 5 and the drum 2 by a flexible pipe 7 which is shaken by the vibration of the member 1. The drum is rotated anti-clockwise on vibration of the member 1 by the interaction of the piles 4 and 6 and the powder is thus dispersed in the chamber 3. Suction is applied through pipes 17, 15, 14 and the powder is drawn from the chamber 3 and most of it is passed via a member 16 back into the reservoir 8, the rest of it being extracted by a filter box, not shown. Excess powder which falls from the web because of the sharp turn at the roller 19, falls on to the sloping floor 18 of the chamber 3 and is recirculated by the drum 2. It is stated that the bronze powder may be replaced by another suitable powder.

Title: A process for treating synthetic polyester or polyamide fibres or cords to improve their ability to adhere to a rubbery composition
IPC: C08J5/00
Filed: 1961-09-06
Abstract: The adhesion of synthetic polyester and polyamide fibres and cords to rubbery compositions is improved by treating them with a composition comprising of polyepoxide and water and then heating them at a temperature sufficient to remove a portion but not all of the polyepoxide but below the softening temperature of the fibres or cords, in the absence of a curing agent for the polyepoxide.  The epoxy group may be present in the polyepoxide in an amount greater than 0.2 equivalents per 100 grams of polyepoxide.  Suitable polyepoxides are those obtained by the reaction of a halogen-containing epoxide with a polyhydric alcohol or ester or ether thereof, a hydroxy aldelyde, a hydroxy-ketone, a mercapto alcohol, a halogenated polyhydric alcohol or a polyhydric phenol, numerous examples of which are given.  The treating composition may contain 0.5-10% by weight of the polyepoxide.  The polyepoxide may be removed from the fibres or cords by vaporization, decomposition or burning by heating to a temperature of above 290 DEG F. for 1-5 minutes.  10-95% by weight of the polyepoxide may be removed by heating.  The fibres and cords may subsequently be treated with an adhesive composition comprising a polyhydric phenol, an aldehyde and a rubber latex e.g. a copolymer of a conjugated diene and vinyl pyridines or styrene, heated at a temperature similar to those used in the heat treatment of the polyepoxide treated fibres and cords, to cure the adhesive and then used to reinforce rubber.

Abstract: 1341530 Rockets ETAT FRANCAIS 11 July 1972 [19 July 1971] 32288/72 Heading  F3A  A military or meteorological rocket comprises an explosive charge 13 which is retracted into the body 1 of the rocket when a block 10 of propellant has been consumed. Detonation of the explosive charge by a fuze 17 thereby fragments the whole rocket. A head 5 containing the explosive charge is formed with a valve member 7 which is urged against a seat 6 by the pressure of gas trapped in the body 1 prior to firing. A removable pin 15 locks the head in position. When the rocket is launched, the pressure of propellant gases continue to urge the valve member against its seat until overcome by the force of a spring 9 and the air pressure acting on a cap 14. A latch 16 locks the head in its retracted position and also serves to arm the fuze 17. The block of propellant is glued to the valve member 7 and is supported by a spring 11. In another embodiment (Fig. 3, not shown) the explosive charge is carried by a sleeve which slides externally over the body of the rocket.

Abstract: 818.621. Electric resistance heating. SAUREFABRIK SCHWEIZERHALL. Nov. 11, 1955 [Dec. 30, 1954], No. 32380/55. Class 39(3) In furnaces in which current is passed between vertically spaced electrodes formed as hollow rods, tubes or frames through a solid loose conductive charge e.g. coke for producing water gas or charcoal for producing carbon disulphide, the granular charge is set into vibration adjacent one or both electrodes to ensure good contact therewith and prevent the formation of cavities in the granular charge adjacent an electrode. The vibrations are produced by a vibrator attached to a metal or graphite rod, ring or frame which dips into the granular charge, may be internally cooled and may serve as an auxiliary or main electrode. The granular charge may be vibrated by several vibratable bodies around an electrode, preferably the upper electrode. The supply cable and cooling supply pipes are flexible. The cooling medium may pass into the hollow tube down a central pipe therein and return between the pipe and the tube.

Title: Improvements in the manufacture of photo-electric cells
IPC: H01J40/06
Filed: 1927-12-01
Abstract: 306,996. General Electric Co., Ltd., and Campbell, N. R. Dec. 1, 1927. Vacuum tubes.-A cathode is formed by depositing on a metal electrode a very thin and normally invisible film of photo-sensitive material and sensitizing the film by the passage of a discharge in hydrogen. The red-sensitivity of a cell using potassium as the sensitive material is thereby greatly increased. A layer 2 of silver is deposited on the wall of the cell, which is connected by a tube 6 to an exhaust pump, and by a tube 7 with a vessel 8 containing potassium. After the cell has been baked, exhausted, and cooled, potassium is introduced by heating the vessel 8, the tube 7 being then sealed off. Potassium is deposited on the electrode 2 by heating the remainder of the cell while the electrode is cooled. The electrode is then gently heated until the visible layer of potassium rapidly disappears. when hydrogen at a pressure of 1 mm. is introduced. The presence of hydrogen prevents further diffusion of potassium. When the cell is cool, a discharge of a few milliampÞres is passed for about a. minute with the electrode 2 as cathode and a nickel-gauze electrode 3 as anode. The red-sensitivity appears to be determined by the condition of the silver coating, and probably with an oxygen-containing film on its surface; it may be desirable to admit oxygen just before potassium is introduced, or during its introduction. The red-sensitivity of caesium is not greatly increased by making the film thin. Specification 291,763 is referred to.
