IPC: C04B35/465
Filed: 1945-08-29
Abstract: A composition consisting substantially of calcium titanate is produced by firing to vitrification a mixture of commercial grade titanium dioxide and a compound of calcium, e.g., lime or calcium carbonate, which exists as calcium oxide at the temperature of vitrification and is present in an amount sufficient to react stoichiometrically with the titanium dioxide to form calcium titanate, with a slight excess of calcium oxide sufficient to combine with the impurities or most of the impurities in the titanium dioxide.  The firing may be performed in the presence of a flux yielding phosphorous pentoxide, such as ammonium diacid phosphate.ALSO:A dielectric composition consisting substantially of calcium titanate is produced by firing to vitrification a mixture of commercial grade titanium dioxide and a compound of calcium, e.g., lime or calcium carbonate, which exists as calcium oxide at the temperature of vitrification and is present in an amount sufficient to react stoichiometrically with the titanium dioxide to form calcium titanate, with a slight excess of calcium oxide sufficient to combine with the impurities or most of the impurities in the titanium dioxide.

Title: Improvements in or relating to box tills
IPC: B41L5/08
Filed: 1957-07-15
Abstract: 890,113. Autographic registers. GROSS, H., and GROSS, S. July 14, 1958 [July 15, 1957], No. 22336/57. Class 16 In a combined autographic register and cash till, the transactions are written through an aperture on to a paper sheet carried by a rotatable disc which is rotated by movements of the cash drawer or by a hand-operated key. As shown, the apparatus comprises an inner frame 11, an outer cover 14 bolted to the frame, a hinged top lid 16 having a writing aperture 17, and a disc 21 rotatably mounted beneath the lid 16. The disc has ratchet teeth 23 engagable by a driving pawl 24 which can be actuated by a key 27 on a pivoted lever 25. A spring-urged lever 41 has a roller 40 thereon which engages the teeth 23 to register the disc 21 and prevent a reverse rotation thereof. A hand-lever 47 is provided for reeasing the roller 40 to enable the disc to be rotated freely by a knob 45. The stroke of the pawl 24 is controlled by stops, and the nose of the pawl is held within the teeth 23 of the disc 21 during the working stroke by an abutment plate 39. A circular paper sheet 50 is held on the disc by register pins 51, and the sheet has annular writing zones 54-56 printed thereon: the sheet also has an annular series of numbers 52 thereon corresponding to the numbers of teeth 23 on the disc, and these are exposed through an aperture 57 in the lid 16. The key-operated lever 25 moves a latch to release a spring-urged cash drawer 12 when the disc 21 is being rotated: this arrangement can be modified so that a partial depression of the key 27 releases the cash drawer without rotating the disc 21. In another modification, the driving pawl 24 is actuated to rotate the disc 21 by the movement of the cash drawer when it is released by depressing the key 27: or the cash drawer is not spring-loaded, and is adapted to actuate the driving' pawl 24 when it is opened or closed.

Title: Improvements in or relating to apparatus for the manufacture of sponged latex
Filed: 1951-09-25
Abstract: 694,284. Mixing appliances. ALDERFER, S. W. Sept. 25, 1951, No. 22388/51. Class 86 Apparatus for aerating and beating a liquid such as rubber latex in the manufacture of sponged latex comprises a conical rotor, a conical shell surrounding the rotor, the surface of the rotor and the opposing surface of the shell being constructed with ribs which intersect, the tops of opposing ribs being closely spaced so that liquid passing between them will be subjected to a shearing action while the ribs on the rotor tend to propel the liquid towards the apex of the shell, and means for introducing a continuously flowing stream of liquid and air into the apex of the shell and thence into the space between the rotor and the shell. A conical rotor 10 having in its surface one or more spiral grooves 74 which form one or more spiral ribs, is mounted for rotation within a stationary conical shell 16 having on its internal surface a plurality of longitudinal ribs 66, 67. The major parts of the surfaces of the rotor 10 and shell 16 are parallel but at the lower end an upwardly tapering space 65 is formed which leads from a preliminary mixing and feed chamber 82. Latex and air are fed at predetermined rates into upper and lower portions respectively of the chamber 82, which are on opposite sides of an air-permeable diaphragm 85 of finely woven nylon sheeting, so that air passes upwardly through the diaphragm to become disseminated in the latex. The dissemination of air in the latex is assisted by a paddle 92 mounted on a shaft 90 depending from the rotor. The pre-mixed latex and air is impelled upwardly by the force of the incoming latex and enters the space between the rotor and shell where it is subjected to shearing action, the direction of rotation of the rotor being such that the effect of the spiral 74 is to oppose the upward flow of latex. The foamed latex emerges at the upper end of the cones and passes into a chamber 72 defined by a cylindrical wall 69 where it has a rolling and rotating motion which is utilized to effect mixing of setting or gelling agents introduced at measured rates by delivery pipes 130, 141, Fig. 1 (not shown) opening above the chamber 72, the final mixture being delivered by a shoot 121 to moulds or the like. The shell 16 is vertically displaceable to permit adjustment of the spacing between the rotor and shell and to allow the rotor and shell to be separated for cleaning purposes.

Title: Improvements in, or relating to, percussive tools
IPC: B25D9/04
Filed: 1925-09-09
Abstract: 265,646. Rayner, G. H. T., and Rayner, P. Sept. 9, 1925. Percussive drills.- In a hammer drilling-machine, the cylinder q carrying the hammer r is carried and reciprocated by a piston b which works in a cylinder a under the action of fluid distributed by a valve g. The cylinder a is mounted on the usual cradle with a screw feeding-device. When fluid pressure is admitted to the rear of cylinder a for forcing the cylinder q forward, fluid pressure operates the hammer r. When during the forward cutting operation the port k is opened, the rear end of the cylinder is put to exhaust and the cylinder q is withdrawn. The hammer supply is then cut off, and the hammer is made inoperative. The central valve head g controls the admission, the end heads m, n control the exhaust. The ends of the valve-chest are alternately put to pressure and exhaust by cross ports j, k controlled by the piston b to operate the valve. The stroke of piston b is varied by the screw handle 5.

The layer 13 prevents " cross-talk " and can comprise copperactivated CdS in a lithium containing silicate glass or enamel which is irradiated through an apertured mask 12 to be rendered conductive only at the crossings. The electroluminescent layer 16 can comprise ZnS activated by chlorine and manganese. A lacquer layer 15 prevents this radiation from passing to layer 16 and also prevents the electroluminescence from affecting the layer 13. Auxiliary island electrodes 14 may be provided at each crossing. The panel can be used for radar display or adapted for display of colour television pictures by dividing the conductors into sub-groups and using different electroluminescent stripes, or by using different electroluminescent layers which are superimposed, the extinction principle being utilized. The provision, instead of the layer 13, of individual elements at the crossings or of a silicon or germanium semi-conductive layer with PN junctions, is discussed although not forming part of the invention.
