Filed: 1965-09-08
Abstract: 1,071,650. Filling and emptying tanks. PARKER - HANNIFIN CORPORATION. Sept. 8, 1965 [Sept. 30, 1964], No. 38371/65. Heading B8T. [Also in Divisions F2 and G3] A valve arrangement for filling and discharging a tank (1), Fig. 1 (not shown), comprises a main closure member (40), Fig. 2 (not shown), defining a chamber (35) having restricted communication with the inlet via an annular passage surrounding a varying diameter rod (38) extending through the main closure member. Two pilot orifices (36, 37) constitute outlets from the chamber, these orifices cooperating with pilot valves (18, 19) normally unseated under the action of the pressure generated by jet level sensors (14, 15), in pipes (16, 17), the sensors being supplied via a pipe (8) from a manifold (6) provided with an inlet (5) and an outlet (7). To fill the tank (1), an interlock arm (33) is moved to allow a nozzle (4) to be coupled to the inlet (5) and to connect a source (31) of air pressure via valves (34, 30) to a vent valve (26) to open the latter. When the liquid level immerses the first sensor (14), the pilot orifice (36) is closed and the valve closure member (40) moves towards its closed position to a point determined by an enlargement (46) of the rod (38), the enlargement serving to restrict the entry of liquid into the chamber (35) to create a pressure balance across the valve. When the liquid level immerses the second sensor (15), the pilot orifice (37) is closed and the main valve member (40) closes. The interlock arm (33) is then returned to the position shown and the valve (34) exhausts a cylinder (23) to close the vent valve (26). To empty the tank, the outlet (7) is opened and (a) valve (28) is used to open the vent valve (26). On opening a valve (53), air from the source (31) passes, via the valves (32, 28) and pipes (51, 52) to a space (54) where it raises a piston (48) connected to the rod (38), the latter having a pin (47) which engages the valve closure member (40) to unseat the latter. One of the sensors (14, 15) may be omitted, the one remaining serving to close the main valve member (40).

Abstract: Ketones are produced by reacting at an elevated temperature hexene-1, heptene-1, or octene-1 with a mixture of cupric chloride, cupric acetate and water having a pH in the range 1.5 to 2.4 in the presence of a platinum group metal compound.  Preferred reaction temperatures are between 20 DEG  C. and 120 DEG  C. and the molar ratios of Cl-/H2O, Cu++/H2O and Pd/H2O are preferably 0.05-0.25, 0.01-0.25, and 0.0008-0.013, respectively.  The process may be operated in a batchwise or continuous manner and the ketone recovered from the organic phase of the reaction product by, for example, solvent extraction or fractional, extractive or azeotropic distillation. Residual olefines from the organic phase may be treated over an isomerization catalyst and the 1-isomer returned to the ketone - forming reaction. Cuprous chloride produced during the ketone-forming reaction may be regenerated by, for example, treatment with a molecular oxygen containing gas during said reaction or in a separate stage after separation of the aqueous and organic phases of the reaction product.  The examples relate to the use of palladium chloride as the metal compound.  Reference has been directed by the Comptroller to Specifications 884,962 and 898,790.

Patent GB-394322-A (GB)
Abstract: 394,322. Cash registers. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.-(Assignees of Racz, E. ; 3709, Richton Street, Detroit, Michigan, U.S.A.) Dec. 18, 1931, No. 35123. Convention date, Dec. 20, 1930. [Class 106 (i).] A cash register consists of a known type of calculating-machine which is now provided with a drawer adapted to be released in all totaltaking operations except when the totalizer is clear. A single-item key may be used to effect drawer-release when a single-item transaction is being registered. Parts of the mechanism may be replaced by others to enable the drawer to be released in all operations or in all except a non-add operation. The calculating machine illustrated is of the known Burroughs Portable type and is mounted on a housing 40 containing the drawer 50. Drawer-release in total-taking. The drawer is spring-urged outwardly and is normally restrained by a latch 53 fixed on a shaft 54 to which is also secured a voke 56. Mounted on the yoke is a member 62 extending below a plunger 60 adapted to be depressed by the arm 72 of a yoke 70. The other arm 73 of this yoke carries a pass-by pawl 74 extended to engage a pin 76 on an arm 77 of a yoke pivoted at 79. The other arm 80 of this yoke cooperates with a lever 95 carried by a bail 99 extending behind the impression hammers 102. When the total or sub-total key T, ST is depressed and the link 32 lowered a lever 82 is rocked so that a pin 85 cams a yoke 88 counterclockwise to rock a voke 92 clockwise and so raise the lever 95 to engage the arm 80. When therefore the hammers are retracted prior to striking, the lever operates the yoke 78 and thus rocks the pass-by pawl into the path of the link 18 so that as this member terminates its rearward stroke, the yoke 70 is operated and the drawer released. As described in Specification 265,140, [Class 106 (i), Calculating &c.], if no significant digits stand on the totalizer the hammers do not move and the drawer therefore is not released. The characterprinting hammer is cut away at 110 to allow its movement in all operations, without affecting the bail 99. Single-items. When a transaction consists of only one item a key SI may be used so that the drawer may be released without requiring a total-taking operation. For this purpose the key rocks a lever 123 to throw up the pass-by pawl into effective position. Modifications. (1) The key SI may also act as a non-add key if it is not desired to enter the single-items in a totalizer. (2) The yoke 70 may be replaced by another having an arm permanently in the path of the link 18 so that the drawer is freed at every operation of the machine. (3) Yet another form of yoke may be substituted, with a pass-by pawl normally effective but adapted to be disabled by the non-add key so that the drawer is released at every operation except when this key is used. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specifications 387,635 and 387,973, which does not appear in the Specification as accepted.
