Abstract: 1,059,485. Hydraulic shoe drum brakes. ROCKWELL - STANDARD CORPORATION. May 5, 1964 [July 19, 1963; Aug. 15, 1963], No. 18567/64. Headings F2E and F2F. A brake system comprising a primary brake, 36 or 38, having a pair of shoes 40, 42 moved apart by a pair of pistons 80, 82 in a primary actuator 32, a secondary brake 64, 70 having an actuator 60 or 66 to which fluid pressure is applied at 44 by movement of a shoe 40 when applied, in the direction of rotation of the brake drum, adjustment means 83 for compensating for wear of the shoes, and means 136 independent of the adjustment 83 to transmit movement of said brake shoe 40 to the other shoe 42 to eliminate the need for additional fluid in the primary actuator 32. The unactuated ends of the shoes 40 and 42 are held by a return-spring 104 in contact with pistons 96 and 98 in a power-cylinder housing 92 attached by a flange 94 to a brake spider 78. The pistons 96 and 98 have slots 100, 102 to receive the ends of the shoes, small diameter guide stems 114, 116 and springs 124, 126 which bias them outwards towards lock rings 128, 130. An outlet 108 to conduits 48 or 50 and 54 leads to the actuators 60 and 66. The junction 52 between these conduits has a pipe 72 which feeds oil from the primary circuit through a non-return valve (not shown) for topping-up the secondary circuit. Fig. 3 shows an alternative power cylinder 140 for the secondary actuators 60 and 66 in which a stud 154 actuates a piston 160 or 162 in the power cylinder and also transmits the movement of the leading shoe 40 to the trailing shoe 42. In this instance the piston on the side of the leading shoe is entrained by the stud 150 to compress the spring 164 and decrease the internal volume of the cylinder, whilst the other piston is held against its retaining ring 168.

Title: Process for manufacturing from a thermoplastic material shaped articles having a predominantly closed cell structure
IPC: B29C44/44
Filed: 1962-05-16
Abstract: In a process for manufacturing from a thermoplastic material shaped articles having a substantially closed-cell structure, the pre-foamed particles obtained by heating thermoplastic material particles containing an inflating agent are first aged for at least one hour at substantially atmospheric pressure and then at elevated gas pressure, and the final working up into shaped articles takes place before the super-atmospheric pressure in the pre-foamed material is reduced to atmospheric pressure by permeation. Doubly pre-expanded particles, which have been aged (suitably at least partly at elevated pressure) between the first and second pre-expansion treatments, can be treated.  The pressure in the ageing step is preferably 2 to 8 atm. abs. but may be higher. The mould or matrix used in the shaping need only be partly filled, e.g. to 75%, with the aged particles. Oxygen, nitrogen, carbon dioxide, helium, lower hydrocarbons, halogenated hydrocarbons, but preferably air, are suitable for the ageing at elevated pressure. When air is used the resulting treated particles have an air content higher than that required for equilibrium with air at atmospheric pressure. the treated particles slowly lose their internal gas pressure and are preferably moulded within 10 hours of manufacture.  The process in applicable to polystyrene beads, foam waste having a closed cell structure and reduced to particles (of size 0.2 to 1.0 cm.), styrene acrylonitrile copolymers, and polystyrene flame-proofed, e.g. by chlorinated paraffin wax and antimony oxide.

Abstract: 289,759. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude, (Assignees of Soc. Chimique de la Grande Paroisse Azote et Produits Chimiques). April 30, 1927, [Convention date]. Catalytic apparatus.-The reacting gases are circulated over two or more distinct groups of surfaces enclosing the catalytic material and the transfer of heat is regulated by varying the proportions of the gases which circulate over the respective surfaces. In the arrangement shown the catalyst-containing chamber C contains a set of inner heatexchanging tubes D communicating with an inner chamber E. Gas supplied through the inlet G passes through branch tubes F, H provided with valves R, S and communicating respectively with the space E and the space surrounding the chamber C. By regulating the valves the proportions of gas taking these two paths and consequently the heat-exchanging effect may be varied. Alternatively the separation of the gas into portions to effect regulation of heatexchanging effects may take place on the outlet side of the apparatus. The apparatus may be applied, e.g. in respect of variable quantities of carbon monoxide occuring in a mixture of hydrogen and nitrogen intended for conversion into amnionia, the valves being regulated so as to effect the conversion into methane, correctly in spite of variations of the percentage of carbon monoxide.
