Title: Improvements in or relating to valves
IPC: A61C17/14
Filed: 1924-09-09
Abstract: 232,544. Pieper, A. F. April 18, 1924, [Convention date]. Multiple-way valves; actuating-mechanism.-A multi-way valve device employs a single valve spindle having longitudinal movement for actuating one of the valve and rotary movement for actuating the other. The device is shown applied to a dental spittoon such as that described in Specification 222,114. The valve comprises a casting having an inlet 25, Fig. 3, communicating through a passage 27 with a chamber 28 from which water is distributed to the spittoon for flushing and other purposes. The passage 27 is controlled by a valve 29 integral with the spindle 62. The chamber 28 also contains a sliding valve member 33, the two ends of which control a port leading to a passage 37 and thence to the flushing nozzle, and a part leading to a passage 40 and thence to a saliva-ejecting device, respectively. The valve 33 is operated by a rotary movement of the spindle 62, a projection 64 engaging in a groove 34 in the, valve. The valve 30 is operated by an independent longitudinal movement of the spindle. The spindle passes through a stuffing-box 68 having a shoulder 69 bearing on a shoulder 70 in the casing. The stuffing-box is held in position by a screwed sleeve 71, which supports a tubular part 72 which can be rotated independently of the sleeve and the spindle. The part 72 has a lug 74 engaging a corresponding lug 75 on a sleeve 76 which compresses the packing 78. The packing may thus be compressed by the rotary movement, only of the part 72. The outer end of the part 72 is. internally threaded to reeceive an actuating-member 82 mounted on the spindle between a shoulder 80 and head 81. Rotation of the member 82 effects a simple longitudinal movement of the spindle to actuate the valve 30. Rotation of the spindle is effected independently by means of a wing 83.

Abstract: 443,822. Type-printing telegraphy. CREED & CO., Ltd., Telegraph House, Croydon.-(Assignees of Zenner, W. J.; Hawthorne Lane, Des Plaines, Illinois, U.S.A.) July 27, 1935, No. 21379. Convention date, Nov. 1, 1934. [Class 40 (iii)] Means responsive to an opening of the line of predetermined length causes the opening of the circuit of a teleprinter motor which is thereafter closed either by a subsequent closing of the line circuit or in a modification by the subsequent closing, opening and further closing of the line. Upon opening the line circuit, the line magnet 21 releases its armature 20 to allow the camshaft 16 to be driven by motor M and thus set up by cams 13 an allblank combination on the discs 11. The detector bar 12 is selected thereby and dropping into aligned slots in the discs 11 moves the extension 40 of the lever 47 into operative relation with the bail 35 which is subsequently raised to rotate the lever 47. Extensions of the lever 47 open the switch 41 in the motor circuit 72 and transfer the magnet 63 to the line circuit through switch 44, 45, 46. A latch 56 retains the lever 47 until a subsequent closing of the line circuit energizes the magnet 63 to close the circuit of a magnet 55 to release the latch. The member 40 is released from engagement with the lever 12 by a bell-crank lever 53 actuated by the bail 35 in its uppermost position. In order that the first closure of the line after the motor has been stopped is rendered ineffective to restart it a second latch 76, Fig. 3, may be provided which locks the arm 47, in its uppermost position the latch 76 being moved to allow the arm 47 to drop on to the latch 56 when the latter moves on the subsequent de-energization of magnet 55.

Patent GB-795585-A (GB)
Title: Improvements in or relating to process for the manufacture of aerated fully synthetic fibres
IPC: D01D5/247
Filed: 1955-07-27
Abstract: Voids are formed in fully synthetic fibres by treating them successively with a swelling agent, an aqueous solution or suspension of a catalyst and a peroxy compound.  The fibres may be polyamide, polyester or polyacrylonitrile fibres and may have been previously dried.  The swelling agent may be chloracetic acid, acetic acid, formic acid, mineral acids, saturated salt solutions, chloral hydrate solution, phenols, glycols or, in the case of polyacrylonitrile fibres, an ethanolic solution of calcium thiocyanate.  The term peroxy compound includes only hydrogen peroxide and peroxides yielding hydrogen peroxide when treated with dilute acids.  The catalyst is of the type which promotes the decomposition of the peroxide and may be a heavy metal, either free or in the form of a salt.  Aqueous solutions of potassium permanganate, of manganous salts such as the chloride or sulphate, and of cobaltous salts, such as cobaltous sulphate, are preferred.  If an acidic swelling agent is used, it is preferred to neutralize the acid after the fibres have been treated successively with the swelling agent and the catalyst and prior to the treatment with a peroxy compound.  In an example, undelustred "Nylon 6" fibres are swollen by immersion for 1 minute in 70 per cent aqueous chloracetic acid, rinsed with water and then dipped into a 10 per cent aqueous solution of manganous sulphate. The fibres are washed with water for a short time, insufficient to remove completely the manganous sulphate from them, and passed through a 2 per cent aqueous solution of caustic soda.  They are then treated for 5 minutes with 40 per cent hydrogen peroxide, washed with water and dried.  The fibres have a delustred appearance, due to the presence inside them of voids produced by the oxygen evolved from the hydrogen peroxide.  Other examples are also given.

Filed: 1938-07-25
Abstract: 513,813. Sex hormones. NAAMLOOZE VENNOOTSCHAP ORGANON. July 25, 1938, No. 22065. Convention date, July 25, 1937 [Class 2 (iii)] Compounds of the cyclopentano polyhydrophenanthrene series having a keto group in the side-chain at the C20 atom are prepared by condensing saturated or unsaturated etiocholanic or etioallocholanic acid esters, or ring substituted derivatives thereof, with monocarboxylic or #-dicarboxylic acids having a free hydrogen at the alpha-carbon atom or functional derivatives thereof in the presence of alkali metals and decomposing the product with an acid. The condensation products may be saponified and decarboxylated to give simple ketones. The condensation may be represented as:- XCOOR1 + CH3 O.CH2 COOR = X CO.CH (OCH3) COOR + R1 OH. where XCOOR1 represents an alkyl ester of a saturated ox unsaturated etiocholanic or etioallocholanic acid and R is an alkyl group. By saponification and decarboxylation, this condensation product yields a ketone of the formula XCO CH 2 OH. In the examples, 3-oxy-#<5>:<6>-etiocholenic acid methyl ester on condensation with ethyl acetate and methoxy-ethyl acetate and subsequent saponification and decarboxylation yields respectively #<5>:<6>-pregnenol-3-one-20 and #<5>:<6>- pregnendiol-3.21-one-20. The products are of therapeutic value.. The Specification as open to inspection under Sect. 91 specifies the use of halogen, hydroxyl, alkoxyl, acyloxyl and carbonyl derivatives of esters of saturated or unsaturated etiocholanic or etioallocholanic acids as parent materials and also mentions the use of alkaline earth metals as condensing agents. This subjectmatter does not appear in the Specification as accepted.
