Title: Improvements in or relating to sealing of metal to vitrified materials such as glass, silica, porcelain and the like
IPC: C03C27/04
Filed: 1944-05-04
Abstract: 584,935. Sealing metal to vitreous material. CROSSLEY, P. B., and ENFIELD ROLLING MILLS, Ltd. May 4,1944, No. 8472. [Class 36] A water-insoluble basic flux for sealing metal to glass or other vitrified material is compounded of lead oxide and a hydrated lead borate. The lead oxide may be replaced in part by one or more other metal oxides of the general formula RO or R2O3, e.g. oxides of barium, magnesium, manganese and bismuth. One or more alkali metal oxides, e.g. sodium, potassium or lithium, may also be embodied in the flux. The hydrated lead borate may be prepared by precipitation from a solution of lead acetate by means of borax, warmed with ammonia, and then boiled with a solution of boric acid. The flux may be used dry, or in water suspension. The stability of the suspension may be enhanced by the addition of a hydrogel, sodium silicate or ammonium nitrate. When the metal and vitrefied materials have widely different expansion coefficients, a flux having a coefficient more suitably related to that of the metal may be fused on the latter before applying the sealing- flux. A finishing lustre may be given to the sealed parts by the application of ethereal-oil solutions of metal resinates and subsequent firing to free the metal oxide for combination with the flux.

Title: Improvements in hydraulic shock absorbers
IPC: F16F9/26
Filed: 1926-03-31
Abstract: 271,986. Royce, F. H. March 31, 1926. Fluid-friction vibration-dampers. - In apparatus in which a piston moving in a closed cylinder forms liquid compression chambers at each end and the liquid is forced from one chamber to the other through definite passages, a passage way provided in the piston contains a one-way spring-loaded valve opening to pressure in one direction, while though the movable wall of this valve is arranged another one-way spring-loaded valve opening to pressure in the reverse direction. The hollow piston c is operated through a link b<8> and arm b<6> from a shaft b mounted in bearings in the walls of a projection from the casing of the apparatus. The cylinder a is formed in this casing, and is partly surrounded by a chamber forming an oil reservoir. Oil is drawn, when required, into the ends of the cylinder from the bottom of the chamber through a cylindrical filtering device a<7>, passages a<9> and one-way ball valves a<12>. The piston is provided with two longitudinal passages c<5> which connect the lift end of the cylinder with a chamber c<3> formed in a transverse partition c<2>. One side of the chamber c<3> forms a seat for a cylindrical valve c<6> slidable in guides in the piston but preferably not concentric therewith. The valve is kept on its seat by the outer helical spring c<11> so that a predetermined resistance is provided to the movement of the piston to the left. The end of the cylindrical valve provides a seat for a one-way valve d contacted by the inner helical spring d<5>. Movement of the piston in one direction is thus resisted by a force which may be equal to or different from the resistance in the opposite direction. A small one-way valve e<2> allows escape of air.

Filed: 1937-03-30
Abstract: 477,503. Time switches. FISHER, D. March 30, 1937, No. 8935. [Class 38 (v)] A time switch for turning a wireless set on and off at predetermined times comprises two clockwork-driven cams 27 which make one revolution, say, every twenty-four hours and which co-operate with two levers 33, 38 to move the spring contact blade 29 into and out of engagement with a fixed contact 32. The cams 27 and their spindles 24 may be set to the required times by knobs (not shown), the spindles 24 slipping, while the setting is being effected, relatively to 24-hour dials which are driven round by the ordinary clockwork mechanism. The lever 33 is pivoted at 34, is biassed by a spring 43 towards the cam 27 and has pivoted to it at 37 the lever 38 which is biassed by another spring 43 but cannot move under this bias because its arm 40 is engaged by a projection (not shown) beneath the contact spring 29. As the upper cam 27 rotates, its projection eventually presses back and then releases the arm 35. The consequent oscillation of the arm 40 causes a tooth 41 on it to slip behind the projection on the spring 29 and then carry the spring with it into engagement with the contact 32. At a later time the lower cam 27 rotates the lever 38 about its pivot 37 releasing the spring 29 which returns to its original " open " position. The clockwork may consist of a synchronous motor.
