Title: Process for preparing fat-soluble salts of bismuth
IPC: C07F9/94
Filed: 1930-10-24
Abstract: Fat-soluble basic bismuth salts are obtained by reaction between a malonic acid ester substituted by a branched radical having at least seven atoms of carbon and a solution of a basic bismuth salt, such as the nitrate, dissolved by means of a polyhydroxylic compound such as mannitol.  In examples, dipropylcarbinyl malonic ester is treated with alcoholic soda to replace one of its two ethyl groups and then with bismuth nitrate, and the salt formed extracted with benzene or ether.  The solvent is evaporated, and the salt taken up in olive oil for injection purposes; and octylmalonic ester is treated with alcoholic soda as above and then with bismuth nitrate at 50 DEG  C., the bismuth salt collecting at a liquid at the bottom of the vessel. When taken up in benzene and heated the salt loses a molecule of water to yield a salt of the formula  <FORM:0356550/III/1> Dipropylcarbinyl malonic ester is prepared by condensing the bromide of dipropylcarbinol with ethylsodiomalonate.  Octylmalonic ester is similarly prepared from the bromide of methyl-hexyl-carbinol.ALSO:Fat-soluble basic bismuth salts are obtained by reaction between a malonic acid ester substituted by a branched radical having at least seven atoms of carbon and a solution of a basic bismuth salt, such as the nitrate, dissolved by means of a polyhydroxylic compound such as mannitol.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T8/32
Filed: 1935-11-20
Abstract: 466,119. Fluid - pressure brakes. KERSHAW, A. G., SIMMONS, A. W., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Nov. 20, 1935, No. 32178. [Class 103 (i)] A fluid-pressure brake controlled by a train pipe and electrically is identical with that described in Specification 463,946 except that the retardation controller is replaced by a centrifugal device 80 rotated by'a part dependent on the train speed and also subject to the action of brake cylinder pressure acting on a piston 82 so that braking is dependent on the speed of the train and on the degree of braking exerted. While the speed is sufficiently high the governor 81 assisted by a spring 80 maintains the contact arm 76 in engagement with the contact 77. When brake cylinder pressure acting on piston 82 overcomes the governor 81 and the spring 80 due to fall of speed, arm 76 disengages the first contact 77, and engages the second contact 78, causing the brake application valve 12 to close and the circuit of the holding valve 13 to be maintained. Further decrease of speed causes the arm 76 to disengage the contact 78 and engage the contact 79 so as to open the blow down valve 14 to release the brake cylinder pressure until the reduction allows the arm 76 to return to the contacts 78 or 77. Specification 464,780 also is referred to.

Title: X-ray tables
IPC: A61B6/00
Filed: 1968-07-05
Abstract: 1,224,814. Counterbalancing. PICKER CORP. 15 July, 1968 [27 July, 1967], No. 32191/68. Heading B8B. [Also in Division H5] A counterweight system, provided in the tower assembly of an X-ray table to support an imageing device in moving towards and away from the table top, is such that movement of the imageing device through a given distance moves the counterweight through a greater distance, so as to provide mechanical advantage, the counterweight being so mounted that it can assume a position above the top of the tower when the imageing device approaches the table top. The arrangement is shown diagramatically in Figs. 6 and 7. The imageing device 17 is fixed at point 30 to the cable run 31 around a pair of pulleys 32. A further point 34 on the same cable is attached to an intermediate carriage 33. Carriage 33 supports pulleys 35 having cable 37 around them which cable is attached to the tower at point 36 and to the counterweight carriage 38 at point 40, this carriage 38 being fitted with wheels 39 adapted to move over the surface of intermediate carriage 33. Thus movement of the device 17 downwards causes intermediate carriage and also the counterweight carriage to move upwards, wherein since the motion of the counterweight is added to the motion of the intermediate carriage, the counterweight moves through twice the distance of the imaging device. In practice, as shown in Fig. 4, the axes of rotation of pulley 32 are perpendicular to those of pulleys 35, and two pairs of each type of pulley are positioned one pair at each side of the tower 18 and the intermediate carriage 33 (Fig. 3, not shown), respectively. The cable runs 31 and 37 are fitted in two halves, the free ends being bolted at 34 and 36 to the intermediate carriage and the mast 18, respectively. The intermediate carriage is channelshaped, being guided up tower 18 by guide means 59 and rollers 56 attached externally of the channel webs, the counterweight carriage being guided by strip 62 up the inside of the channel on wheels 39. The counterweights have been omitted from the drawing for clarity, but they are supported by horizontal web 62.

Title: Process of producing active carbon in a pulverulent form at low temperatures
IPC: C01B31/08
Filed: 1925-12-22
Abstract: 262,278. Bube, K. Dec. 22, 1925. Materials and compositions for making gas, coke, and other products. - Active carbon in powdered form is produced at low temperatures by heating oils which are normally incapable of being cracked economically, with or without the addition of carbonaceous substances, in pressureresistant vessels to a temperature of from 350‹ to 500‹ C. in such a manner that part of the oil remains liquid during the reaction, and simultaneously discharging the liquid gaseous and solid reaction products through a common outlet. The pulverulent active carbon obtained may then be submitted to a purifying treatment by means of hot water. In an example, producer gas tar obtained from lignite is pumped through pipes heated to between 350‹ and 500‹ C. at such a speed that carbon does not deposit on the walls of the vessel, volatilization within the reaction tube being minimized by means of throttling-valves. In another example, a mixture of powdered lignite with heavy lignite oil is pumped through a tube heated to about 400‹ to 500‹ C. and the exit of the tube is throttled in such a way that carbon, oil, ashes, and gases leave simultaneously. Crude mineral oils rich in asphalt may be employed in admixture with coal, sawdust, or other carbonaceous substances.
