Title: Improvements in or relating to rotary valves, particularly for internal combustion engines
IPC: C07D499/00
Filed: 1927-08-02
Abstract: 284,941. Luyckx, C. Aug. 2, 1927. Addition to 275,557. Regulating. - The timing of the rotary valve l claimed in the parent Specification is varied by angular adjustment of the central core i, which is formed with diametrical exhaust passages k and similar inlet passages (not shown). The valve itself may also be adjusted angularly. By moving the cores backwardly, as shown in Fig. 2, the time of commencement of inlet and exhaust remains the same, but the time of closing is advanced. Adjustment of the core in the opposite direction delays the opening without altering the closing. In order to prevent the opening of exhaust from being advanced in front of the upper dead-centre when the admission is advanced, the exhaust passage k in the core is bevelled off at k<1>. The core is formed at one end with a collar i<1>, Fig. 4, having slots adjustably held by bolts y, the adjustment being effected by gearing u, v and a connection 26 to hand or governor control. Worm gearing may replace the gearing u. v. Valves.-The valve l, rotating between a central core i and the casing, may be formed with collars engaging circular grooves in the casing to prevent leakage.

Abstract: 531,974. Closing envelopes. INTERNATIONAL COIN COUNTING MACHINE CO., Ltd., and RAND, L. A. July 14, 1939, No. 20556. [Class 94 (i)] A machine for moistening and sealing the flaps of envelopes comprises presser feet that press on a feed belt, and a resilient member that presses on a fixed lower member, for preventing the passage of more than one envelope at a time to the moistening and sealing devices. The moistening device can be converted to permit removal of a water reservoir. The envelopes are piloted with their flaps upwards in a hopper 1, Figs. 1 and 2, having one side wall, 6, adjustable to suit envelopes of different widths. The bottom envelope is fed under the rear wall 3 by conveyer belts 8, 9 preferably of rubber with curved surfaces, and the envelope is pressed against the belts by resiliently-mounted presser feet 21. A stripper 25, Fig. 4, of resilient material is mounted between the pressers 21 and rests on a lower member having two ribs 27, 28, preferably highly polished, which provide spaced contacts with the stripper. This arrangement prevents the feeding forwards of more than one envelope at a time. The envelope is transferred to a belt 29, Figs. 1 and 2, which support the flap edge, the other edge being supported by rubber covered rollers 33, 34. The roller 34 is of somewhat greater diameter and tends to turn the envelope towards the sealing device and ensure even closing of the flap. A spring-loaded plate 35 that presses the envelope on to the belt 29 has an inclined face that causes the flap of the envelope to open slightly. The flap opening and moistening device is hinged to one end of an arm 36, Figs. 1 and 5, the other end of which is pivoted at 37 to the side of the machine. The arm 36 carries a plate 35, Fig. 1, which passes beneath the flap and raises it so that it passes into a slot 40, Fig. 5, between the moistening device and a cover plate. A roller 41, Figs. 1 and 2, presses the flap on to the body of the envelope. The moistening device comprises a shallow tray 44, Fig. 5, having in its upper surface a slot or a felt pad 43 which is supplied with water from a reservoir 45. This reservoir is connected to the tray by a tube 48 the lower end of which is adjusted to determine the level of the water in the tray and keep it constant. By turning the arm 36 through an angle of 180 degrees, the reservoir can be removed and replaced. The water can be heated by an electric heater 49, as described in Specification 532,021.

Title: Process for obtaining salts of sulpho-acids from lignite tar oils
IPC: C07C303/00
Filed: 1920-07-10
Abstract: Lignite tar oil is agitated with a small quantity of cold strong sulphuric acid to remove polymerizable substances and then with a larger quantity of the acid at a higher temperature to effect sulphonation.  The oil layer is agitated with hot dilute caustic soda lye, and after separation from the oil, the sodium sulphonates are precipitated by addition of common salt.  A little water is added to the sulphuric acid layer to remove the excess sulphuric acid, the remaining acid resins are dissolved in a large quantity of water, filtered, and a small amount of common salt is added.  After separating the impure salts thus precipitated, the sodium salts of the sulphonic acids are obtained by treatment of the filtrate with a larger quantity of salt, and are purified by treatment with permanganates.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the purification of the sodium salts by a further fractional precipitation, or by alcohol.  This subject-matter does not appear in the Specification as accepted.
