Title: Improvements in or relating to carboxylic acid polyester salts as suspending agents for lacquers or other film forming suspensions
Inventor: DREKER EMIL
IPC: C09D7/45
Filed: 1961-03-07
Abstract: A suspending agent for film-forming suspension comprises a solution in an organic solvent of a salt of a polyester and a polyamine (other than an aliphatic diamine) or a polyamidoamine. The polyester is the reaction product of (a) a polyhydric alcohol (e.g. glycerine, 1:2:6-hexanetriol, trimethylol propane, pentaerythritol, sorbitol, triethanolamine, a mixture of butine-2-:4diol and hexanetriol or a mixture of glycerine and triethanolamine), (b) a polycarboxylic acid (e.g. phthalic or maleic acid) and (c) a saturated or unsaturated fatty acid containing 10-20 carbon atoms or an ester thereof (e.g. castor oil or its fatty acids, soya fatty acids, tall oil fatty acids, coconut fatty acids or ricinoleic acid). The amino compound may be tetraethylene pentamine, a long chain aliphatic polyamine, a cycloaliphatic polyamine or a reaction product of dipropylene triamine with one or more of adipic acid, phthalic anhydride, castor oil fatty acids, soya fatty acids or tall oil fatty acids. The organic solvent may be a mixture of xylene with butanol, isopropanol or diacetone alcohol.  The suspending agent may be added to alkyd resin lacquers which may also contain a pigment or filler (e.g. one or more of chrome yellow, heavy spar, zinc white or titanium dioxide), a cyclohexanone resin, a skin-protecting agent, a flowing agent (e.g. benzoic or crotonic acid), a drier (e.g. cobalt, lead and manganese naphthenates) and a diluent (e.g. one or more of xylene, white spirit and butanol).  Specification 887,241 is referred to.ALSO:A suspending agent for film forming suspensions comprises, dissolved in an organic solvent, an amine salt of a carboxylic acid polyester of a polyalcohol, the amine being a polyamine (excluding aliphatic diamines) or a polyamido amine.  Specified polyalcohols are glycerine, hexanetriol, trimethylolpropane, pentaerythritol, sorbitol and triethanolamine.  The polyalcohol is first esterified with a fatty acid then with a di- or polycarboxylic acid, e.g. maleic or phthalic acid, whereby one of the carboxylic groups of the latter acid is left free for salt formation.

Title: Improvements relating to valve devices for fluid pressure braking apparatus for railway and like vehicles
IPC: B60T15/50
Filed: 1948-03-25
Abstract: 653,010. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and SIMMONS, A. W. March 25, 1948, No. 8770. [Class 103 (i)] In a fluid-pressure brake system for railway and like vehicles, a charging control valve is provided for controlling the flow of air to the auxiliary reservoir to recharge the latter, this valve being controlled by the difference in the pressures at the inlet and outlet of a charging choke device through which all the air to the auxiliary reservoir passes. As shown, the control valve comprises a member 14 urged against the piston 1 of the triple valve by a spring 8. Charging of the auxiliary reservoir 23 from the train pipe 8 normally takes place by way of pipe 4, filter 7, passages 5, 6 and 19, choke passage 20, passage 22, chamber 16 and passage 24. In the event, however, of the pressure rising rapidly in piston chamber 2, which is in permanent communication with passage 6 by port 25, the piston 1 is moved to the left, from the full release position shown, against the force of spring 13 so that the valve member 14 following up tends to throttle the passage 6, 19 thus reducing the charging rate. The slide valves 10, 12 are kept in position by the abutment 11. The piston 1 moves back when the pressures in the auxiliary reservoir 23 and chamber 2 are more nearly equalized. Although, as shown, the valve member 14 is formed as an integral part of the triple valve assembly, it is stated that the control valve device could be interposed either in the pipe leading from the brake pipe to the triple valve or in the pipe from the triple valve to auxiliary reservoir.

Title: Improvements in and relating to mercury and like fluid flow electric switches
IPC: H01H29/10
Filed: 1933-03-24
Abstract: 396,001. Mercury and other conducting-liquid switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Moos, F.; 110, Irving Street, Jersey City, New Jersey, U.S.A.). March 24, 1933, No. 8976. Convention date, March 25, 1932. [Class 38 (v).] In tilting mercury and like switches with a time delay caused by the passage of the mercury or other conducting liquid through a small orifice, the orifice 6 is formed in a baffle 5 forming part of a separate trough or vessel 4 adapted to be mounted within the normal vitreous envelope of the switch.. By this means, all the parts that determine the period of the time delay may be adjusted to their final relative position before sealing into the envelope, and mass production of switches with uniform time delay is facilitated. Fig. 2 shows a construction having one electrode 2 welded to the trough 4 which is of iron, chrome iron or other metal and the other electrode 3 brought through a glass tube to a point above the trough 4. This point is adjusted as required and the trough and leads then introduced into the envelope and sealed. The envelope may contain hydrogen or ammonia. The amount of mercury 7 is just sufficient to fill the space behind the baffle 5 when the switch is tilted in a counterclockwise direction. The mercury then slowly passes through the orifice 6 and when it reaches the electrode 3 closes the circuit. When the tube is tilted back, the mercury flows over the baffle 5 causing a quick break. Fig. 5 shows a modification in which the trough is of vitreous or refractory material and is formed with a cup 29 enclosing the one electrode 23. Contact is then made and broken over the wall 28 of the cup. In other modifications, Figs. 4 and 8 (not shown), the time delay occurs when the switch is turned to open the circuit instead of to close the circuit, and in yet another modification, Figs. 10 and 11 (not shown), the switch has a slow make as well as a slow break.

Filed: 1916-06-29
Abstract: 104,611. Curry, M., and Cook, A. June 29, 1916. Driving-arrangements.-In a device for use in tying the spindle bands of spinning or twisting frames or other handdriven machinery, whereby the bands may be tied at a predetermined tension, a part of the band to be tied is passed round a member which yields under the tension placed upon the band in tying, and which is locked in relation to its support when the predetermined tension is reached. The device is supported by a socket 1, which can be secured by a screw 2 to the bolster of the spinning- spindle. The band is brought round a hook 12 on a rod 11 sliding in a cylinder 5 carried by the socket 1. The knot is partly tied and then pulled tight to draw the rod 11 out against the action of a spring 7, the tension of which can be adjusted, until a spring-controlled locking-dog 15 enters a groove 14 in the rod 11. The tension in the band is then at the predetermined amount, and the knot is completed. The rod 11 is then rotated by a handle 13 to allow the band to slip off the hook 12 into the groove in the wharl. A pin in the cylinder 5 sliding in a groove 17 in the rod 11 normally prevents rotation of the rod, but when in the desired position, the pin enters the groove 14 and allows rotation. When the rod 11 is rotated back into its normal position, the locking-dog 15 is withdrawn by the trigger 16, and the rod is drawn back against a cushioning-spring 19.
