Filed: 1923-09-29
Abstract: 230,123. White, C. H. Sept. 29, 1923. Actuated by running axle; hand actuation; force-transmitting mechanism. - The brakes of railway wagons are adapted to be applied by winding gear driven by an axle of the vehicle through a clutch which can be put into engagement by side levers operable from the ground. Manual means for directly turning the. winding drum and means for automatically effecting the disengagement of the clutch when a predetermined pressure has been applied to the brakes, are provided. A pair of drums 9, 9<1> to which the ends of the chain 10 are connected, are freely mounted upon a countershaft 4 carried by arms 6, 6<1> connected by a cross-bar 7 and pivoted at 8, 8<1> to fixed brackets. Friction driving wheels 3, 3<1> keyed on the shaft 4 ride on driving sleeves 2, 2' fixed on the running axle 1 of the vehicle. A toothed clutch member 18 splined on the shaft 4 is adapted to be slid into engagement with corresponding teeth on one or other of the drums 9, 9<1> according to the direction of travel of the vehicle by means of levers 19, 19<1> extending from the sides of the vehicle and connected to the clutch member 18 by a sliding rod 18 and a strap 23. The chain 10 passes around pulleys 11 on the pull rod 12 connected to the brakes and also around a pulley 14 on a rod 15 slidable in a fixed bracket against the action of a spring 16. A pin projects beneath the operating strip of the clutch member 23 into a triangular frame member 17 interposed in the length of the rod 15, the arrangement being such that when in the application of the brakes the tension in the chain becomes sufficient to overcome the spring 16 the rod 15 slides and the side members of the frame 17 acting against the pin effect disengagement of the clutch and thus limit the braking pressure. The drum 9 can be turned directly for applying the brakes by hand wheels 28, 28' and gearing 26, 27. Instead of a pair of drums, a single drum and a clutch member at each end thereof may be provided and the drum may be mounted upon the axle of the vehicle. Means for controlling the brakes from the top of a wagon or the interior of a brake van may be provided.

Title: Sodium-sulphur electric cells
IPC: H01M10/39
Filed: 1973-05-22
Abstract: 1465902 Molten electrode cell INDUSTRY SECRETARY OF STATE FOR 17 May 1974 [22 May 1973] 24391/73 Heading H1B Each cell of a nested pair of cells 15, Figs. 2, 3, comprises an aluminium casing 16 receiving a tubular beta-alumina membrane 17 closed at its open end by a metal terminal cap 22. The membrane 17 defines an inner compartment 18 receiving molten sodium and an outer annular compartment 19 receiving molten sulphur impregnated in carbon felt 21. The chambers 20 form by the upper longitudinal extremities of the casing 16 provide space for expansion of the contents of the compartment 19 due to the products of cathodic reaction. To ensure that the surface of the membrane 17 is always wetted by the sodium irrespective of its level a tubular member 24 of wire mesh is held against the inner surface of the membrane by a perforated support 25, the member 24 acting as a wick to draw up the sodium by capillary action. The cells are series-connected by a strap 23. In other forms of the invention (Figs. 4 and 5,  not shown) non-nesting battery cells have the axis of the membrane 17 offset from the axis of the casing, the upper larger annular spaces providing room for expansion of the reaction products. In a further modification (Fig. 6, not shown) the relative positions of the sodium and sulphur are reversed and the wick effect is produced by a narrow annular gap between the membrane and the casing to which sodium is fed by gravity. The same principle is used in the modification of Figs. 10, 10a (not shown) in which a number of membranes of rectangular shape are placed, with narrow gaps therebetween, in a closely fitting casing which provides a storage space for sodium at one end thereof.

Title: Improvements in or relating to vacuum distillation of high boiling point products
IPC: C11B3/12
Filed: 1932-09-05
Abstract: In the distillation of high-boiling substances such as fatty acids, glycerine, volatile products and fatty acids contained in oils, fats, waxes, &c. without using carrier vapour, and at absolute pressures lower than 10 mm. of mercury, reflux condensation is minimized by providing the still 2 with a deep vapour space 3 above the liquid in the still, and with a tubular baffle 4, so that the vapours first ascend to the top of the still and then descent in the space between the baffle 4 and the still wall 2 to the outlet 5 leading to the condensing system 6, 7, vacuum-producing means such as steam ejectors 8, 9, and a final tubular condenser 11.  When the substance to be distilled contains substantial proportions of water or other low-boiling <PICT:0408259/III/1> impurities, the bulk of these may be removed in a preliminary still 1 of similar construction operating at a higher absolute pressure of 25--75 mm. of mercury (e.g. 50 mm. when the main still operates at 2 mm.).  The vapours from the still 1 pass through a tubular condenser 19 and pipe 20 to the condenser 11, the outlet P of which is connected to a vacuum pump 10.  The space between the baffle 4 and the still wall 2 may be heated by a steam coil 16, the condensate collecting at the bottom of condenser 6 may be heated by a coil 17, and the cooling water of condenser 6 may be maintained at a controlled temperature of over 100 DEG  C. by means of an auxiliary condenser 18 which condenses the steam produced by the boiling of the cooling water and returns the condensed water to the condenser 6.  The condensate from condenser 19 is discharged into a vacuum receiver 21 co-operating with an extraction pump 22 delivering at atmospheric pressure at 23, and the condensate formed in the baffle space of still 2, and in condensers 6 and 7 is withdrawn by pumps 25, 27, 28 through cooling coils 24, 26.  The liquid in the stills is heated by circulating through the tubes 12 by means of the centrifugal impellers 13, as described in Specification 280,666, [Class 32], the tubes 12 being surrounded by a heating medium such as high-pressure steam.
