Title: Improvements in or relating to railway vehicle braking systems
IPC: B60T13/46
Filed: 1928-02-09
Abstract: 307,187. Glascodine, R. T., McDermid, W. F., and Spencer, A. Feb. 9, 1928. Addition to 285,209. Fluid-pressure.-The valve device for automatic vacuum brakes described in the parent Specification is provided with an opening between the brake cylinder and the valve piston chamber which is controlled by a valve in a similar manner to the opening between the piston chamber and the train pipe so as to ensure a uniform rate of flow of air from the brake cylinder during release as well as to the brake cylinder during application irrespective of the pressure difference as between the train-pipe and the brake cylinder. The train-pipe 9 and brake cylinder pipe 10 communicate with the piston chamber 1 through openings 3, 2, respectively, controlled by shoulders 5, 4 on the piston stem 6<a>. The piston 6 has openings 7 providing a restricted passage for air through the piston. A spring 8 abuts through washers 13 on the heads of pins 12. upon which the piston stem 6<a> can slide. The washers also engage shoulders formed within the piston stem. During application, if the train-pipe pressure together with the weight of the piston is sufficient to overcome the spring 8 and the brake cylinder pressure, the piston moves downwardly to restrict more or less the passage 3 and thus the rate at which the air flows into the brake cylinder. Similarly in releasing the brake if the excess of the brake cylinder pressure over the trainpipe pressure is sufficient to overcome at first the weight of the piston and subsequently also the resistance of the spring 8, the shoulder 4 throttles the flow of air from the brake cylinder to the train-pipe. The upper stem 12 may, like the lower stem, normally contact with the casing, but to render the device more sensitive, in the release action, in view of the fact that the upward movement of the piston is opposed by the weight thereof, the upper stem may as shown be normally spaced from the casing so that the spring is not at first effective.

IPC: D01G31/00
Filed: 1917-03-26
Abstract: 111,224. Ackroyd, W., and Barker, E. March 26, 1917. Stop-motions. - The object is to stop the feed-rollers of carding- engines or to drive them in the reverse direction and if necessary to stop the whole machine, when t h e taker-in slows down or stops through over-feeding &c. The feed-rollers are driven from the doffer through a side shaft d, Fig. 7, and bevel-wheels d<1>, d<2>, d<3> so arranged that, by moving the shaft d sideways, the bevel-wheel d<1> may be made to engage with either of the bevel-wheels d<2>, d<3>. The movement sideways of the shaft d is effected by the movement of a spring lever h, which is connected with the bearing k<2> of the shaft d by means of the pin-and-slot arrangement k<1>, k<@> and rests upon the loose half g<2> of a clutch, which is rotated on the taker-in shaft, at a speed slightly less than that at which the taker-in is rotated, by a band from the shaft of the main cylinder. When the carding-engine is running, the two parts g<1>, g<2> of the clutch are in gear, but should the taker-in slow down or stop, the part g<2> is slid along the shaft, and the lever h moves into the position shown stopping or reversing the feed-rolers. For re-setting the parts, the lever h is moved by a handle &c., whereby the side shaft d is again moved sideways and the clutch part y<2> is moved into gear with the part g<1> by a spring. For stopping the engine entirely, the shaft of the lever h is continued to the opposite side of the carding- engine and there connected with a longitudinal catch rod, which, by means of a resilient catch, normally holds the driving-strap on the fast pulley. Means are provided whereby the longitudinal catch rod may be operated and the engine stopped by hand when desired.

Abstract: 1,218,821. Alkali metal carbonates. DYNAMIT NOBEL A.G. 26 Jan., 1968 [28 Jan., 1967], No. 4337/68. Heading C1A. Alkali metal carbonate is produced from alkali metal liquors containing alkali metal hydroxide, where the desired concentration of carbonate is greater than that of the hydroxide, by introducing the following to a cation exchange material in an ion exchanger: (i) the alkali metal liquor, whereby at least some of the alkali metal ions are adsorbed on the exchange material; (ii) successive fractions, of increasing concentration, of a first alkali metal carbonate solution; (iii) successive fractions of a second solution comprising alkali metal carbonate (in decreasing concentration) and bicarbonate (increasing concentration), the total concentration of carbonate and bicarbonate in each fraction being not less than that of the desired carbonate; (iv) fraction(s) of a third alkali metal bicarbonate, of total concentration below that of the product but of greater (at least double) bicarbonate ion concentration than the alkali metal ions in the product solution; (v) fraction(s) of a fourth solution of alkali metal bicarbonate, in decreasing concentrations; (vi) eluting the respective above solutions from the exchanger and collecting the desired fractions; and (vii) treating the effluent fractions of the third and fourth solutions with CO 2  to convert carbonate therein to bicarbonate, which bicarbonate may be used in subsequent cycles. The treatment with CO 2  is preferably at a pressure up to 2 atmospheres above that of the liquid in the exchanger. The ion exchanger preferably comprises a " very weakly acid cation exchanger " (pK of 7-11) and a " weakly acid cation exchanger " (pK of 4-7) downstream thereof, alkali metal ions being removed from the latter with aqueous CO 2  solution, the bicarbonate produced being added to the fractions of the third and fourth solutions. Various ion exchangers are referred to. The alkali metal liquor may comprise alkali metal hydroxide and an alkali metal salt; in examples the alkali metals are sodium and potassium respectively.

IPC: B24B3/34
Filed: 1916-03-25
Abstract: 102,659. Williams, E. March 25, 1916. Disk apparatus for grinding V- thread screw-cutting tools. The spindle of the grinding-disk f is mounted in a slide which is adjustable by means of a screw d ; a weight e is connected to the slide to take up back-lash between the screw and its nut. The table g is rotatable abou a vertical axis and is carried on a box h at the upper end of a vertical slide i, to which reciprocating motion is imparted during the grinding operation, by an eccentric and rod k. The spindle of the eccentric is driven from the main shaft of the machine by worm gearing. The tool-holder p is adjustable radially on the table and is arranged to present the tool to the disk at the angle corresponding to the clearance required at the front of the tool. The table g is provided with a handle g by which it may be turned between a pair of adjustable stops r. At one limit of the movement, one of the faces of the tool is presented to the disk, and at the other limit, the other face is presented. In passing from one end of the movement to the other, the nose of the tool is ground to a circular form. In order to grind the nose to the correct radius, the axis of the table must be set at the required distance from the face of the disk. This is effected by lightly grinding a separate gauge-piece, which is mounted co-axially with the table and can be rotated in contact with the disk. The diameter of the gauge-piece is then measured, and the difference between its radius and that required for the nose represents the amount by which the grinding-disk must be ad justed axially.
