Abstract: 531,392. Automatic circuit-breakers ; contacts. ELECTRICAL APPARATUS CO., Ltd., and BARBOUR, R. H. June 1, 1939, No. 16137. [Class 38 (v)] A polyphase overload and unbalance protective device of the kind in which current responsive thermal elements in the phases operate a switch to disconnect the apparatus, has the thermal element of each phase acting as secondary of a transformer, the primary of which is a coil for carrying the main current. If the heat so produced in the thermal element is insufficient, a piece of copper may be added. The transformers each comprise a two part coil 18, 19 and an apertured upwardly-flexing bimetal strip 21 and copper heater 22 slipped over the common core 14, Fig. 4. The strips 21 pass between two stirrups 25, 26 pivoted at 28 and to the plate 12, Fig. 5, the lower stirrup 26 being urged against the strips 21 by a spring 29 and the upper resting on the strips, whereby the stirrups and strips normally move together. The stirrup 25 carries a triangular metal plate 35, Fig. 5, to which is pivoted at 36 a metal channel-member 37 normally urged by a spring 39 to engage a flange 41 on a metal bracket 42 on stirrup 26. The member 37 serves as a combined latch and movable contact co-operating with the flange 41 as a second contact. If the strips 21 move unevenly due to phase-unbalance, the stirrups move relatively to one another, as in Specification 382,695, thus opening an auxiliary circuit to cut off the main current. An overload release is provided by the lower stirrup being arrested by a stop 45, Fig. 6, which is preferably in the form of an ambient temperature compensator, and is mounted on a pivoted lever 47 co-operating with a current-setting cam 51. The contact-arm 37 is relatched by a roller 60 on a pivoted arm 57 having a nose 56 engageable by a cam 55 on a spring-returned spindle 52.

Title: A process for treating hard water
IPC: C09K23/52
Filed: 1955-06-06
Abstract: A process for treating clear hard water to reduce its scale-forming tendency comprises adding to it a water-soluble substantially linear synthetic polymer having a molecular weight of at least 1,000 in an amount not exceeding 20 per cent by weight of the hardness-imparting compounds present in the water. Examples of polymers are: the homo-polymers of the acids of the acrylic series; their amides; polyvinyl pyridinium alkyl halides; copolymers of acids of the acrylic series with polymerizable vinyl compounds; interpolymers of alpha-, beta-unsaturated dicarboxylic acids, of the amides or of the partial alkyl esters of these acids, or of the salts of the partial alkyl esters or of the substituted amides.  The polycarboxylic acids may be reacted with salt-forming metal compounds.  In the deposition from hard water of calcium carbonate by soda ash, the precipitate is rendered non-adherent to chemical equipment by the presence of a polymer according to the invention.  It is stated to be known to add an alphahalogen-substituted polyacrylic acid to hard water so as to prevent the formation of calcium and magnesium precipitates.

[Class 64 (ii).] In a chemical heating appliance rendered active by admission of air, a single valve may be opened positively to admit the air and also opens automatically to allow vapour &c. to escape. A spring 13 normally holds a valve 15 against its seat 14, and excludes air from the interior of a casing containing a mass 6 of sodium acetate and water. The valve may be raised by a ring 17 to admit air, and a flared head 18 carried by a stem 11 engages an extension 10 and closes the air passage when the valve is raised to its limit ; the head 18 projects sufficiently to become immersed in the mass 6 when the casing is in a horizontal position. After generation of heat by crystallization, the chemical is restored to the potential condition by placing the flask in boiling water during which operation any excess pressure will open the valve to release any air or vapour.

Abstract: 166,118. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Hodgkinson, F.). July 7, 1920, [Convention date]. Testing balance of rotary apparatus.-The dynamic balance of a rotary body, for example a turbine rotor, is determined by rotating the rotor between vibratory supports, and applying a compensating force separately at each end. The rotor 8 is mounted in oscillatable bearings 13 in adjustable standards 6, 7 carried upon I-section supports 14, 15 of sufficient fiexibility to allow vibration. The standards are enclosed by housings 16, 17 provided with stops 18 moved by hand-wheels 19 so as to engage the standards to check or stop their vibrations. Adjustable springs 20 are also interposed between the housings and standards to damp or accentuate the vibrations.. Each standard supports a shaft 34 driven by helical gears 35, 40 and sprocket gearing from the motor 9 through a lay shaft 37. A disc 23 is secured to this shaft and carries a fixed counterweight 33 and a radially adjustable mass 24 which may be shifted, during rotation of the disc, by manipulating buttons 31, 32 connected by bevel-gears with the radial screwed spindle carrying the mass 24. The helical gear 40 may be slid along its shaft 36 by shifting a rod 41 in order to vary the angular relation of the mass 24 and disc 23 with respect to the rotor. In order to test and compensatethe rotor, it is rotated by the motor through flexible shafting 47, and the masses 24 on the synchronously-rotated discs 23 are adjusted' radially or angularly or both until vibration of the standards ceases.
