IPC: C10G1/00
Filed: 1928-10-06
Abstract: 323,773. Strevens, J. L. Oct. 6, 1928. Composition fuel.-Torbanites, shales, and other solid fuels are ground with oil to a fine suspension which is subjected to a cracking treatment and filtered to separate a powdered fuel residuum. In an example, coal ground until 90 per cent. of it passes a sieve of 200 meshes per sq. inch is mixed with 15 per cent by weight of a fuel oil residuum and 5 per cent of a colloid. The mixture is diluted with <1>/3 of its weight of oil and is pumped at 300-360‹ C. and 40 atmospheres pressure into tubular digesters where it is heated to 400‹ C. The mixture passes through pressure cracking tubes at 400-800‹ C. to soaking tubes, a whirling motion being imparted to prevent deposition of solids; the pressure is then released and the light hydrocarbons are distilled off. The hot residue is filtered, and the solid matter may be used directly as a powdered fuel or may be briquetted. Specification 18232/14, [Class 91, Oils &c.], is referred to.

Abstract: 771,459. Systems of charging and discharging condensers. GENERAL ANILINE & FILM CORPORATION. Oct. 11, 1954 [Oct. 27, 1953], No. 29280/54. Class 38 (4). In order to transfer the charge on a condenser 5 completely to an uncharged condenser 10, the two are connected in series in a closed conducting path including a resistor 22 through which is caused to flow a current proportional to the voltage across the condenser 5, the current being in such a direction as to discharge the condenser 5 and persisting until the terminal voltage of the condenser reaches zero. In the arrangement shown, any one of three condensers 10 of different capacities may be selected to receive the transferred charge by a switch 37. The terminal voltage of condenser 5 is applied over a cathode follower valve 8 to an amplifier 16 having a negative feedback circuit 21, 22 arranged to give an overall voltage gain of unity. The voltage across the feedback resistor 22 is thus proportional to the terminal voltage and so causes condenser 5 to discharge down to zero volts into condenser 10. A voltmeter, effectively in shunt with resistor 22 may be calibrated in terms of charge transferred to condenser 10.

Abstract: 1,187,446. Vacuum switches. GENERAL ELECTRIC CO. 26 June, 1967 [5 Aug., 1966], No. 29320/67. Heading H1N. A vacuum switch has its contacts 13, 14 biased into the closed position by differential pressure acting on a bellows 12 against the bias of a spring 33. The contacts are positively coupled to a member 16 which has a lost-motion connection 18 to an actuating member 17. Should the differential pressure fall due to partial loss of vacuum in the switch envelope, the lost motion connection permits the spring 33 to move the member 16 to open the contacts 13, 14. The movement of the member 16 also releases latching balls 43 which free a cap 40 for upward movement under the bias of a spring 41. The cap operates a switch 50 to close contacts 52 in an alarm circuit and to open contacts 54 in circuit with the drive motor 22 for an operating cam 19.
