Filed: 1941-04-29
Abstract: 554,558. Resolution of pantothenic acid. MERCK & CO., Inc. April 29, 1941, No. 5521. Convention date, July 3, 1940. [Class 2 (iii)] Racemic pantothenic acid is resolved by reacting the racemic acid with an alkaloid or an alkaloidal salt or a quaternary base derived therefrom to form the corresponding racemic salt from which the optically active enantiomorph is separated by crystallization, and the free acid liberated therefrom. In examples (1) Racemic pantothenic acid is resolved by means of its quinine salt formed from quinine methyl hydroxide, and crystallized from alcohol by successive additions of ether, and recrystallized from a mixture of alcohol and ether. (2) Racemic pantothenic acid is resolved by the crvstallization of its cinchonidine salt from alcohols. Other alkaloidal salts such as ephedrine, quinine, strychnine and brucine may also be used. The Specification as open to inspection under Sect. 91 includes also examples of the preparation of alkaloidal salts of optically active pantothenic acids. The salts whose preparation is described are (1) the quinine salt of (+) pantothenic acid prepared from quinine methyl hydroxide. (2) the quinine salt of (-) pantothenic acid. (3) the cinchonidine salt of (+) pantothenic acid. (4) the ephedrine salt of (+) pantothenic acid. (5) the quinine salt of (+) pantothenic acid prepared from the pure alkaloid. (6) the strychnine salt of (+) pantothenic acid. (7) the brucine salt of (+) pantothenic acid. This subject-matter does not appear in the Specification as accepted.

Abstract: 877,278. Holders for packs of interleaved paper. PENNEY, E. Feb. 18, 1960 [Feb. 18, 1959], No. 5556/59. Class 18. A holder for packs of interleaved toilet paper or paper towels accommodates an " in use " pack and a reserve pack and has means preventing pilfering of either pack. When the lower pack is almost exhausted a finger is passed through the usual opening 15 through which the sheets are withdrawn and engages and pivots the top end of a lever 30 pivoted at 29. The lever 30 releases the base 20 of the holder and the exhausted pack is withdrawn. As the base is opened a member 31 moves down and a spring urged member 32 becomes approximately horizontal and supports and prevents removal of the reserve pack. When the base is reclosed, the member 31 returns the member 32 to its initial position and the reserve pack falls to the lower position. A spring urged member 22 is pressed downwards when a reserve pack is introduced into the top of the holder and has spikes 24 which prevent withdrawal of the pack through the open lid 17 of the holder. The lid may be locked by an operating lever inside the holder and having an arm engaging a flange 36 on the lid. In a modification the member 32 is omitted and a flange 35 on the base is extended to partly cover the open base and prevent withdrawal therethrough of a full pack.

Title: An improved damper controlling mechanism for furnaces
IPC: F23N3/08
Filed: 1925-03-02
Abstract: 248,555. Puddington, A. W. March 2, 1925. Valves controlled by pilot or relay valves.-A fluid - pressure actuated valve for controlling the supply of air to a furnace is operated by two diaphragms having different areas and acted on by two different pressures, air being supplied when the pressure on the diaphragm of larger area is relieved, as by a relief valve actuated on opening the furnace door. The closure member 54, Fig. 4, of the valve 27 is carried by a stem 41 fixed to a diaphragm 34 rigidly connected to a larger diaphragm 37 upon the under side of which acts water or other pressure in a cylinder 30 supplied from a pipe 51 with a valve 52. When a fire doors 11 is opened an eccentric projection 48, Fig. 5, on the hinge-pin 49 opens a relief valve 45 connected by a pipe 44 with the valve 52, and allows the water to escape to the ash-pit. The relief of pressure causes the closure member 54 to be forced from its seat by the steam pressure acting on its upper surface, allowing the steam to act on the diaphragm 34 to complete the opening of the valve. Steam is thus supplied both to a diaphragm 25 to open the air damper 15 and to steam injector nozzles 12. On closing the fire door the relief valve 45 closes under the action of a spring 57 and pressure is again built up in the pipe 44 and cylinder 30 to close the valve 27, the time required being determined by the adjustment of the water supply valve 52.

Filed: 1975-02-12
Abstract: 1493514 Vehicle skid detectors K H F WERNER 12 Feb 1975 5911/75 Heading F2F [Also in Division G1] A sensor for comparing the angular deceleration of a vehicle wheel with the linear vehicle deceleration, in an antiskid system, consists of a mass 6 resiliently attached to a shaft 3, which is parallel to the vehicle longitudinal axis and driven in proportion to the wheel rotational speed, so that angular deceleration causes the mass to twist relative to the shaft and linear deceleration causes axial displacement. This causes a feeler 9 to move in an angled groove 8, (Fig. 1a) and to touch the sides of the groove in the event of excessive wheel deceleration, thus making electrical contact. The contact may be replaced by a magnetic coupling (Figs. 2 and 4, not shown), or by a system of strain gauges (Fig. 3, not shown), or by photo-electric means (Fig. 5, not shown).
