Abstract: A layer structure type, clay-like, synthetic silicate has the empirical formula nSiO2: Al2O3 : mAB : x.H2O, the layer lattice comprisin the silica, the alumina and the ions B, where n is from 2.4 to 3.0; m is from 0.2 to 0.6, A is one equivalent of an exchangeable cation having a valency of not greater than 2 and is external to the lattice, B is a negative ion FOH- or 1/2 O= or mixtures thereof; x is from 2.0 to 3.5 at 50% relative humidity, and said material is characterized by a d001 spacing at said humidity which extends from a lower limit of 10.4 <\>rA to an upper limit of 12.0 <\>rA when A is monovalent, to 14.7 <\>rA when A is divalent and to a value intermediate between 12.0 and 14.7 <\>rA when A includes both monovalent and divalent cations. A can be H+, NH4+, Na+, Zi+, K+\h 1/2 Ca++ 1/2 Mg++, 1/2 Sr++ or 1/2 Ba++ or mixtures thereof. Preferred values of the variable parameters are n = 2.5, m = 0.52, x = 2.7, A is NH4+ or Na+, B is 1/2 O= and the d001, spacing is 10.7 <\>rA. Calcination of the ammonium derivative produces the hydrogen form.  The above materials are produced by a hydrothermal treatment in an autoclave, at a temperature in the range 280-315 DEG  C. under its autogenous pressure of a mixture comprising water, Al2O3, SiO2, together with NH4+, Na+, Li, K, Ca++, Ba++, Sr++ or mixtures thereof with an equivalent amount of OH-, F- or mixtures thereof in which mixture Al2O3:SiO2 = 2.7 to 3.3 and OH- or F-: Al2O3 is 0.2 to 0.6. The hydrothermal treatment preferably does not exceed 72 hours being most preferably 48 hours.  The alumino silicates of the invention may be dehydrated preferably at a temperature of 500-700 DEG  C. to produce catalysts.  They may also be used as drilling mud additives, insecticide carriers and as a desiccant, but they are particularly useful as hydrocarbon cracking catalysts after being subjected to further treatment e.g. calcination or treatment with steam.

Abstract: 750,522. Hydraulic shock absorbers. BUTCHER, N. E., MACKNESS, A. J., and SANKEY, M. Aug. 18, 1954 [Oct. 27, 1953], No. 29694/53. Class 108 (3). In a hydraulic shock absorber for vehicles, the flow of liquid is controlled by a restriction device comprising a plug or pad 28 (Fig. 4) of porous material. In operation, on compression, a valve plate 36 lifts to permit flow through a peripheral series of by-pass ports 35. Fluid displaced by the piston rod is accommodated by a spring-loaded piston 43. On rebound, liquid can only bleed through the porous plug 28. The latter may be retained by a circlip as shown, or by adhesive, and may be composed of thermoplastic synthetic resin or sintered metal. It may consist of a perforated cage containing small particles, finely divided material, or small balls. The plug may be of annular shape having a recuperation valve in its central aperture. It may be made of two different grades of material. A plurality of discs of varying filtration characteristics may be employed in one shock absorber. The porous plug may be mounted in a duct leading between opposite ends of the cylinder, instead of being in the piston. In the construction shown in Fig. 1, a ceramic pad 9 mounted in a flanged cup 10, is urged on to a flange 11 by a spring 14 seating on a flanged member 12 rigid with the piston. On compression movement of the piston, liquid is forced through the pad 9. On upward movement of the piston, the cup 10 lifts from the flange 11 and permits a rapid replenishing flow of liquid.

Title: Hydraulic braking systems
IPC: B60T11/22
Filed: 1952-12-02
Abstract: 731,711. Hydraulic brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Oct. 26, 1953 [Dec. 2, 1952], No. 30497/52. Class 103 (1). In a hydraulic braking system comprising a master cylinder communicating with a liquid reservoir and a hydraulic ally-operated mechanism for actuating a brake, the reservoir is provided with a valve communicating with the atmosphere and spring-loaded so as to maintain the pressure in the reservoir below atmospheric pressure. Fig. 1 illustrates a general arrangement of a hydraulic braking system for a vehicle in which the master cylinder 1 is supplied with hydraulic fluid by a reservoir 3 equipped with a filler cap 7, provided with a spring-loaded valve 14, in the inoperative position of the master-cylinder piston 2 illustrated. An outlet connection from the master cylinder connects the piston and cylinder mechanism 6 associated with each of the wheel brakes (in this case disc brakes) via pipe lines 5. When the system is being primed, the bleed vents are left open and the master cylinder is operated to expel a predetermined quantity of liquid from the system. The liquid level in the reservoir 3 is thereby lowered and since the valve 14 remains closed, by reason of the helical spring 15, to exclude the air from the atmosphere via conduit 12, the pressure of the air in the reservoir falls to a value less than atmospheric pressure. The bleed vents are then closed and when the brake is idle, there is. no force in the system which tends to move the pistons of the brake-actuating mechanisms towards the disc. The sub-atmospheric pressure existing in the system tends to move the pistons backward a small amount to prevent rubbing contact with the disc in the inoperative condition of the brakes. However, when a predetermined sub-atmospheric pressure is reached, due to friction pad wear or leakage, the valve 14 opens against its spring 15 and allows air into the reservoir to bring the pressure therein up to the predetermined value; this value always being lower than atmospheric pressure. Although described in connection with disc brakes, the invention is also applicable to drum or other types of brake. Specification 688,382 is referred to.

Class 38 (v) In an induction or other relay wherein a flag indicator 13 is tripped or otherwise actuated when the relay is actuated, the indicator is prevented from moving into its indicating position excepting when the induction disc 10 is at or near the contactoperating position by the proximity of the surface of the disc 10 to a finger 25. Thus unintentional operation of the indicator by vibration is prevented. The finger 25 forms part of a tripping member 19 pivoted at 20 and is adapted to be displaced by a pin 24 on the disc 10, when the disc nears its contactoperating position, so as to release an arm 21 fixed to the indicator and allow the latter to swing under gravity bias into a display aperture 17. A hole 27 in the disc, through which the finger 25 may project, allows this movement to take place. In a modification the surface of the disc is bent away to allow movement of the finger, and there is no hole 27.
