Title: Process for preparing a silica gel flatting agent
IPC: C01B33/113
Filed: 1955-05-24
Abstract: In the preparation of a silica gel flatting agent by forming a silica hydrogel, washing, drying and grinding the hydrogel, the gel is impregnated after washing with an inert, colourless, high melting point, microcrystalline wax, which is insoluble in the solvent of the varnish or the like in which the fltting agent is to be used.  Alkali metal silicate and acid are reacted to form a hydrosol, which is allowed to form a hydrogel on standing, and the hydrogel is washed, dried and activated at 875-1000 DEG  F.  The gel may be ground and then impregnated in a ball mill or ribbon blender with 15-30 per cent based on the flatting agent, molten wax, or granular gel may be impregnated and then ground. Alternatively, gel and molten wax may be fed simultaneously to a fluid energy mill where the gel is ground by the action of steam or hot compressed air and simultaneously impregnated.  In this alternative process, separate drying may also be dispensed with, as drying occurs with the grinding.  The impregnated gel is rapidly cooled to below the decomposition temperature of the wax in air, and may contain 15-30 per cent wax. The microcrystalline wax should have low acid number, iodine number, and saponification number, say 0-5 and melting-point above 175 DEG F.  The impregnated silica is added to varnishes.  In Example (3) a varnish mixture containing a urea-formaldehyde resin, an alkyd resin, and wax impregnated silica in amount equal to the varnish solids is mixed in a ball mill with thinner to form a varnish.ALSO:In Example (3) a varnish comprises a silica gel flatting agent obtained by forming a silica hydrogel, washing, drying and grinding the hydrogel, and impregnating the gel, after washing, with an inert, colourless, high melting point, microcrystalline wax, which is insoluble in the solvent of the varnish in which the flatting agent is to be used (see Group III), a ureaformaldehyde resin in xylol and an alkyd resin in xylene and petroleum spirit, the wax impregnated silica being in amount equal to the varnish solids.  The varnish may be thinned with a xylol/butanol mixture.

Filed: 1937-05-31
Abstract: 493,647. Dispensing soap tablets. CRAMP, B. May 31, 1937, Nos. 14999 and 16962. [Class 18] An apparatus for displaying and dispensing soap tablets &c. comprises a multiple column storage element 60, Fig. 1, arranged so that the lowest article 64 in each column rests in a recess bounded by a guide 61, Fig. 3, and a cam 63 of such configuration that rotation of the storage element 60 causes the lower end of an article to be pushed outwardly, whereby when it reaches a delivery opening 70, the weight of the column above it causes it to be ejected in the horizontal position. The mechanism is actuated from a lever 4, depression of which rotates a bevel 12, Fig. 7, through a toothed segment 10, these parts being returned by a spring 48, and being connected by a one-way clutch to a sleeve 13 carrying a ratchet 21 held by a spring pawl 55, a clutch 25 connecting the sleeve to the storage element which is thus intermittently rotated.

Title: Mechanical control device for members intended to move simultaneously
IPC: B60T11/04
Filed: 1928-05-25
Abstract: 303,488. Motosacoche Soc. Anon. Jan. 5, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Force-transmitting mechanism.-A mechanical control device for example for the front and rear brakes of a motor vehicle comprises an operative element adapted to move simultaneously two movable elements, the elements being held in engagement with one another, and if the resistance opposing the movement of the members exceeds a certain value they may be displaced one with relation to the other. Sleeves f, g freely mounted on a shaft a and connected respectively by arms i, k to the front and rear wheel brakes of a motor vehicle are provided with helicoidal edges d, e held in engagement by a spring m connecting arms j, l on the sleeves, with the corresponding edges of a cam c fixed on the shaft a. The shaft a and the sleeves are turned as a whole until the resistance to the rotation of a sleeve or sleeves is sufficient to overcome the spring m and cause sliding instead of rotary movement of this sleeve or the sleeves. The sliding movement of the sleeves may be used to control other members for example a couple gear connecting the motor to the wheels. A bowden cable of which the sheath is connected to the arm i and the cable to the arm k is used for this purpose. In a modification a plurality of sleeves are freely mounted on a fixed shaft and held in engagement with one another by compression springs mounted between the ends of the sleeves and collars on the sfaft. The device is operated by an arm on one of the intermediate sleeves. In a modification Fig. 3 a cam 9 is rigid with a fixed shaft 8 and a sleeve 10 is engaged therewith, a further sleeve 11 engaging the sleeve 10. A spring 17 contained in a space between the shaft 8 and the sleeves tends to hold the cam 9 and the sleeve 11 apart. The sleeves and the cam engage each other by faces in the form of inclines of special form and the brakes which are connected to arms 22, 23 on the sleeves 10, 11 are applied by a pivoted arm 19 bearing on the end of the sleeve 11. If the resistance opposed to the rotation of the sleeve 10 is sufficiently great it remains stationary and the sleeve 11 slides upon it if the resistance to rotation of the sleeve 10 is less the two sleeves turns together. The springs may be substituted by a fluid pressure piston.

Title: Improvements in and relating to apparatus for skywriting
IPC: G09F21/16
Filed: 1926-06-18
Abstract: 259,156. Thoresen, E. June 18, 1926. Pyrotechnic signals; visible non-luminous signals.- The apparatus comprises a combination of smoke bombs arranged in positions on an aircraft to represent letters, figures or the like, means for moving the bombs longitudinally of the aircraft, and means for singly dropping the bombs and causing their explosion at different altitudes. The floor of an aeroplane is fitted with a table 9 having longitudinally arranged spaced grooves 10 over which works a conveyer band 2 provided with rectangular openings 11. The conveyer is wound off a roller 3 and on to a roller 4 driven through gearing from an electric motor 7. The table top projects over the base at the end next the roller 4 and a hook 12 secured to the base projects upward and is bent over in position to engage a ring 23 in a bomb 14 carried in one of the openings 11 in the conveyer and travelling along a groove 10. The openings 11 are arranged to form letters, characters or designs and each receives a smoke bomb. Each bomb has a rectangular casing 14 of non-inflammable paste board with a closed top and a base 15 elevated above the sides of the bomb. Above the base 15 is a second base 16. The bomb is filled with a smoke producing powder 17 and arranged centrally in the bomb is a non-inflammable tube 18 in which one end of a fuse 19 is arranged. A firing device is connected to the outer end of the tube and is also connected to a cord 21 coiled on itself between the bases, the free end being connected to a ring 23 after being passed through an opening in the base 15. When the air-craft is just starting to write, the motor 7 is started and the conveyer moves towards the left. The first bomb is fed and the ring 23 engaged by the hook 12 the bomb dropping through an opening 25 in the air-craft. The string is pulled out of the bomb and after falling the length of the string the firing device is pulled to ignite the fuse. The length of fuse in each bomb determines when the latter explodes. To write small letters no fuse need be used the bomb exploding when the device 20 is fired by the string. The strings may be of different lengths and may be fastened to the aeroplane, the bomb sliding along the string until the firing device is pulled. The tube 18 is provided with one or more holes in the top through which the fuse ignites the smoke powder. For sky-writing at night pyrotechnics, parachute flares, &c. are used. Specifications 143,380, 225,203, and 253,061 are referred to.
