Title: Improvements in or relating to mechanical integrating gear
IPC: G01F15/07
Filed: 1930-05-23
Abstract: 352,181. Integrating-apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 23, 1930, No. 15943. Convention date, June 28, 1929. [Class 106 (iv).] In integrating mechanism for measuring instruments in which a driving member is periodically coupled to a counting gear through a coupling member moved in accordance with the values to be measured, a control member is provided in association with the coupling device to interrupt the drive to the counting gear within definite ranges of measurement, e.g. at the lower and upper ends of the indicating scale. As shown in Figs. 1 and 1a a clockwork or other constant speed device 1 drives a spindle 7 on which is secured a member 8 carrying pawls 9 adapted on rotation to engage a ratchet wheel 10 connected by gearing 11, 12 to a counter 16. Secured to the casing by a bridgepiece 17 is a recessed disc 18 surrounding the spindle 7 and adjacent thereto is a second recessed disc 19 loose on the spindle 7 and carrying a toothed segment 20 driven by gearing from a float-actuated rack or other member in accordance with the measured values. Pins 31 on the pawls bear on the discs 18, 19 and the extent of the recess, by adjustment of the disc 19, determines the time a pawl is allowed to engage and drive the ratchet wheel. To prevent registration at the lower end of the scale the toothed segment 20 is provided with a projecting cam surface 40, Fig. 1, with which co-operates a double-armed lever 42 carrying a leaf spring 45 adapted to engage the balance wheel 46 of the clockwork and stop its movement when the projection 44 contacts with the cam surface. In order to adjust its range of action a spring feeler 49, Fig. 2, with a projection 48 may be interposed between the cam surface and the lever 42, the feeler being carried on a manual adjustable arm 47. In a modification, Fig. 4, the arm 42 carries an adjustable contact member 44<1> whereby the effective length of the lever 42 is varied.

Hooks, closed.-Relates to chain, &c., straining and coupling devices for use with anti-skid chains for vehicles in which a cam-lever 8 is pivoted in a link 5 at one end of the chain and passes through a link 6 at the other, and consists in forming the end of the lever as a hook 13 adapted to carry a locking device. In the form shown in Fig. 3, the lock consists of a nut 14 screwed to the hook 13 and provided with flats 15 which are housed in the link, the positions of the pivot and the loop 10 being such that the lock is retained in engagement. In a modification the nut is replaced by an elongated member pivoted on the hook.

Abstract: 203,405. Butterworth, A., Butterworth, A., and Butterworth, H. June 9, 1922. Solidifying and then removing films. - In apparatus of the type wherein the cream &c. to be frozen is spread in a film on a rotary internallycooled drum 14 and removed by a scraper 15 when frozen, the feed-rollers 13 mounted in a trough 8 and the scraper are brought into and out of contact with the drum automatically through the action of a cam 11 on a driven shaft 12. The trough 8, which is supplied with cream &c. from a tank 3 through a cock 6 and shoot 7, is carried by a lever 9 having a roller 10 engaging the cam, while the scraper shaft 16 is actuated from the lever 9 through a link 17.

Patent GB-365949-A (GB)
Title: Improvements in and relating to the denitration of acid which contains nitro-bodies dissolved therein
IPC: C01B17/94
Filed: 1931-06-02
Abstract: <PICT:0365949/III/1> Waste acid comprising sulphuric and nitric acid and dissolved nitro-bodies, such as obtained in nitro-toluene manufacture, is denitrated by treatment with steam with or without hot gases, the amount of steam being such that a nitric acid is obtained in the condensing stage of such concentration, say 20-30 per cent by weight, that complete separation of nitro-bodies therefrom can be attained by cooling.  Alternatively, the necessary concentration may be attained by diluting the condensed nitric acid. Waste acid is led by a tube 1 to a column 2 down which it flows in counter-current to steam introduced by a conduit 3 and hot air by a lower conduit 4.  Denitrated sulphuric acid passes out through tube 28.  30 per cent nitric acid condenses in a condenser 6 and passes to alternately employed cooling and clarifying chambers 8, 9.  The nitro-bodies are removed after standing through a conduit 10.  The gases passing from the condenser 6 proceed through a tube 11 to a tower 12 irrigated with 50-60 per cent nitric acid which absorbs their remaining content of nitrobodies.  The acid from the tower 12 is maintained in constant circulation, being in part led to a cooling chamber 14 where it is freed from excess of nitro-bodies and in part returned to the tower 12; or it can be conveyed through a conduit 36 to the separating vessels 8, 9 and there freed from nitro-bodies, provided the acid in the separating vessels is kept below 30 per cent.  The nitrous gases freed from nitro-bodies issuing from the tower 12 are led successively to towers 16, 17, 18 whereby treatment with water and nitric acid in counter-current they are converted into 50-60 per cent nitric acid.  Water flows through a conduit 19 and down the tower 18, the acid liquid being in part recirculated and in part led to the tower 17.  The acid derived from the tower 17 is in part recirculated in this tower and in part led to the tower 16.  The towers 16, 17 are also fed via a conduit 25 with 30 per cent acid from the separators 8, 9. 50-60 per cent nitric acid passes out through tube 30.ALSO:Waste acid comprising sulphuric and nitric acid and dissolved nitro-bodies, such as obtained in nitrotoluene manufacture, is denitrated by treatment with steam, with or without hot gas, the amount of steam being such that a nitric acid is obtained in the condensing stage of such a concentration, say 20-30 per cent by weight, that complete separation of nitro bodies therefrom can be attained by cooling.  Alternatively, the necessary concentration may be attained by diluting the condensed nitric acid.

Title: Treatment of polyvinyl alcohols
Inventor: BONDY CLEMENS
IPC: C08F8/00
Filed: 1953-06-12
Abstract: Polyvinyl alcohol in suspension in a liquid ionizing medium is treated with hydrogen chloride, bromide or iodide.  The polyvinyl alcohol may be produced by acid or alkaline hydrolysis in which at least 50 per cent of the ester groups are hydrolysed.  Media specified are methyl, ethyl, propyl and butyl alcohols which may also contain up to 20 per cent of water or non-ionizing diluents such as benzene, toluene and halogenated hydrocarbons.  The hydrogen halide may be produced in situ, e.g. by reaction between the medium and acid halides such as thionyl and sulphuryl chlorides, phosphorus trichloride, silicon tetrachloride and phosgene.  Elevated temperatures and pressures may be used.  The products have improved physical properties, e.g. films plasticized with glycerine and cast from aqueous solutions have improved tensile strength.
