Title: Improvements in and relating to brake apparatus for railway vehicles
IPC: B61H9/00
Filed: 1923-03-20
Abstract: 213,756. Jackson, E. M. March 20, 1923. Fluid-pressure.-Relates tu a valve device fur actuating the compressed-air brakes on a locomotive simultaneously and in equal degree with the vacuum brakes on the train, and refers to the type of valve comprising a valve casing connected to the vacuum train pipe at 9 and to the pressure-fluid brake cylinder at 15, the casing being provided with a spindle 27 carrying members of different areas for operating it by differences of pressure when the vacuum brakes are applied, an exhaust port 14 controlled by a slide valve 26, and a port for supplying fluid under pressure to the locomotive brake cylinder normally closed by a valve 21. According to the invention, the larger pressure member 22 is subject to the vacuum train pipe pressure through the port 9 and to atmospheric pressure through the ports 10, whilst the smaller pressure member 25 is subject to locomotive brake cylinder pressure through the port 15, and to the constant pressure of the main or auxiliary reservoir of the pressure brake system through the ports 12, 13. An intermediate piston 23 is also provided in the construction shown, which prevents leakage of air from the left side of the piston 25 to the atmospheric ports 10. In Fig. 2 the valve 2 is shown installed on the locomotive, the connections to the main reservoir 3, the locomotive brake cylinder 36 through the triple valve 1, and the vacuum train pipe 4 being as shown, so that with the va ve in the normal position shown in Fig. 1, the brake cylinder 36 is open to exhaust through the pipe 37, the exhaust port of the triple valve, the pipe 16, and the ports 15, 14. When the vacuum in the train pipe 4 is reduced to apply the brakes on the train, main reservoir pressure acting on the piston 25 moves the pistons to the right so that the valve 26 first closes the exhaust 14, and a nut 33 on the spindle 27 then opens the valve 21 to admit main reservoir air to the brake cylinder 36, until the pressure on the right hand side of the piston 25 balances the pistons in an intermediate position with the valve 21 and the exhaust port 14 both closed. When the vacuum in the train pipe 4 is restored to release the brakes on the train, atmospheric pressure acting on the right hand side of the piston 22 moves the pistons to the left to exhaust the brake cylinder 36 through the port 14. The valve 2 may be cut out when not required by operating a cock 7 to cut off the reservoir 3 from the pipe 5 and to put the latter to exhaust, when the pistons move to the left to uncover the exhaust 14, and the compressed-air brake functions in the usual way through the compressedair driver's valve. The valve may be used with a straight-air locomotive brake by connecting the pipe 16 to the brake cylinder 3G through a double check valve or a manually operated twoway cock; and it may be used on a vehicle carrying compressed-air braking equipment and a through vacuum train pipe by connecting the pipe 5 to the auxiliary reservoir or the compressed-air train pipe.

Filed: 1944-05-05
Abstract: 585,825. Making leaf springs. OMES, Ltd., and MORA, G. May 5, 1944, No. 8575. [Classes 83 (ii) and 83 (iv)] Leaf springs with end lugs for shackle pins are formed by upsetting bar stock to form a head, forging the head in dies to lug shape, supporting the forged end in a corresponding die in the upsetting machine, forging the second end to shape, bending to shape if a curved spring be desired, drilling the lugs for the pins, and finally tempering. Forging-machines.-The ends of the flat bar 33, Fig. 2, are tapered to avoid lateral spread during upsetting, and the bar is supported by a fluid-pressure ram 36 and a steady 37 and is heated and upset between electrode jaws 27, 29 and an electrode anvil 23 hollowed at 43 to suit the head 44 to be formed. The jaw 29 has a liner 31, Fig. 6, cut away at 35 so that contact takes place in the centre of the bar and the jaw 27 has a liner 30 cut away at 34 to ensure contact at the sides of the bar. Even distribution of the heating current is thus obtained, resulting in uniform heating of the bar. The bar is seated in a recess 39, Fig. 7, in the steady and is held by a pivoted top member 40 that swings under a hook 42. When upsetting the second end of the bar, the anvil 36 is fitted with a die 45, Fig. 9, shaped to fit the forged end 48 and prevent binding. A retaining member 49 is pivoted at 50 to a swivelling pin 52 and is swung under a hook 53. Specification 585,822 is referred to.

Patent GB-678963-A (GB)
Title: Process for the pre-treatment of iron-containing catalysts for the hydrogenation of carbon monoxide
IPC: B01J23/78
Filed: 1950-04-06
Abstract: The hydrogenation of carbon monoxide is carried out using an iron catalyst which has been pretreated in the form of a static layer of thickness about 100 cms. or more with a reducing gas containing hydrogen and/or carbon monoxide passing at a velocity of 50-500 cms. per sec. (see Group III).  The synthesis temperature may be lowered and there is an increase in the yield of high boiling hydrocarbons, and a decrease of methane formation; when using a catalyst containing alkali metal compounds, the lowered temperature favours the formation of oxygen-containing products.  An improvement in the CO/H2 consumption ratio is obtained with a single passage of water gas over the catalyst.  The velocity of the reactant gases may be increased, e.g. to 300 litres per litre of catalyst per hour.  In examples, a catalyst prepared by impregnating a precipitate containing iron and copper with potassium silicate is used, and the synthesis temperatures are 209 DEG  and 226 DEG  C.ALSO:In the pretreatment of an iron catalyst, for use in the hydrogenation of carbon monoxide (see Group IV (b)), with a reducing gas containing hydrogen and/or carbon monoxide, the catalyst is in the form of a static layer of thickness about 100 cms. or more (e.g. 80-400 cms.) and the linear gas velocity is from 50-500 cms. per sec. (preferably 100-200 cms. per sec.). The reducing gas should be substantially free from water vapour and carbon dioxide.  An alkali metal compound, in an amount of 1-10 per cent (preferably 4-8 per cent) calculated as K2O and based on the weight of iron, may be present in the catalyst. In examples, a solution containing iron and copper nitrates is treated with sodium carbonate solution, the precipitate impregnated with potassium silicate, and the mass reduced at 300 DEG C in a layer of 100 cms. thickness with a mixture of hydrogen and nitrogen passing at a velocity of 140 cms. per sec.

[Class 40 (iv)] A test relay LK on operation holds over its right-hand winding and reverses the current through its left-hand winding, this reversal causing one of the test relays to drop off when two switches test simultaneously. Alternatively a separate opposing winding may be connected up when the relay operates. In the circuit shown, the test relay has only a single armature which is very quick-acting and is arranged on leaving its back contacts to de-energize the stepping magnet H by removing a short-circuit from the shunted switching relay LKR. On reaching its front contacts it connects ground over the holding winding to the test wiper to mark the line busy. LKR which is made sluggish by the shunt R2 disconnects the shunt to make itself quick to release. Values for the resistances of the circuit elements are given in the Specification. The switch may be of the type described in Specification 391,123.

Title: Method and apparatus for production and maintenance of suspensions
IPC: B01F11/00
Filed: 1976-03-04
Abstract: For the purpose of generating and maintaining suspensions for wet-blasting systems, blades (8, 9) are periodically moved up and down within a mixing vessel (1). The shafts (2, 3) carrying the blades are positioned approximately horizontally and parallel to one another. In this way there results from the rotational movement within angles ( alpha ,  alpha ') an essentially vertically orientated movement of the blades (8, 9), which are fashioned as stirring elements, within the mixing vessel (12). This ensures that, owing to the uniform blending of the suspension, uniform blasting conditions are likewise achieved, and wet-blasting systems can be built which are notable for a low overall height and a constant, defined mixing ratio of the blasting mixture. <IMAGE>
