Title: Improvements in and relating to electrical temperature-regulating apparatus
IPC: G05D23/275
Filed: 1930-01-24
Abstract: 342,125. Thermostats. FABRIK ELEKTR. APPARATE F. SAUTER AKT.- GES., Basle, Switzerland. Jan. 24, 1930, No. 2530. Convention date, Jan. 28, 1929. [Class 64 (ii).) Electrical t e m - perature regulating apparatus comprises a thermometer 1 with two contacts A, E associated with maximum and minimum temperature positions respectively and an electric motor 5 controlling the supply of heat or of cooling fluid, the motor driving a main switch 14 and auxiliary switch 11 which connects the two thermometer contacts in parallel in one of the two positions to which it is moved by the operation of a relay 2 controlled by the contacts. Fig. 1 shows the apparatus in the position to which it has been moved on the attainment of maximum temperature, the relay 2 having been energized by the connection made between contacts A, Z of the thermometer 1, and the motor having been in consequence actuated from the position in which the heating circuit was closed by contact 14 to the open position shown. The auxiliary contact 11 has at the same time been moved to connect contact E to contact A. Thus the fall of the thermometer will produce no movement of the relay 2 or of the mechanism it controls until the mercury has left contact E. When the relay is restored to its rest position by the opening of its circuit at contact E, on the attainment of minimum temperature, the motor will operate the contact 11 to disconnect contacts A and E and no further change can take place until the maximum temperature has been reached. The system is applicable to gas and oil heating installations, and in cooling systems the switch 14 may connect and disconnect the compresser or close and open a distant valve in the brine conduit or controlling the cooling water.

A machine for heat-sealing packages or strips of polythene or similar material, has a pair of co-operating jaws, one of which is composed of metal such as aluminium and is heated by one or more electric heating elements, the other having an engaging face of comparatively soft resilient material such as rubber, a linen or like band being interposed between the jaws ; in performing the sealing operation, the package or sealing strip is introduced between the non- heated jaw and the linen band, and the jaws closed. The machine may comprise a cabinet comprising side plates 1 spaced by rods 2, a cross rod 3 carrying an aluminium bar 4 which is heated by a thermostatically controlled electric element 5 and forms the fixed jaw. A movable jaw 6 having an engaging face formed by a length of rubber tubing 7 is mounted on arms 9 of a pair of levers 10 which are pivoted at 12 and biased by springs 14. A rod 13 connecting the levers 10 engages one arm 16 of of a bell-crank lever 15, pivoted at 21, the other arm 17 of which is connected by a link 18 to the plunger of an electromagnet. 20, which, when energized causes the jaws 4 and 6 to be pressed together for a period regulated by a dashpot device, an endless strip 44 of linen or the like being interposed. The time of closure of the jaws is controlled by a dashpot arrangement comprising a piston 23 working in a cylinder 24, which is mounted on a rod 33 passing loosely through a bracket 25 and biased by a spring 34. The piston is connected by a rod 29 and link 32 to an arm of the lever 15. Operation of a foot switch 21 causes the electromagnet 20 to be energized, closing the jaws 4 and 6 and withdrawing the piston 23. This causes the cylinder 24 to be drawn downwards against the spring 34, permitting the closure of a micro-switch 22, which maintains the circuit through the electromagnet 20 until the admission of air to the cylinder 24 through an adjustable needle-valve controlled by a knob 43 allows the cylinder to rise and reopen the micro-switch 22.

Abstract: 547,012. Uniting by fusion. LINDE AIR PRODUCTS, CO. Feb. 27, 1941, No. 2653. Convention date, April 17, 1940. [Class 83 (iv) ] In fusion welding metal bodies a flexible casing containing a granular fusible mineral material is disposed under the seam to serve as a backing member and weld metal is deposited from the other side, sufficient heat being supplied to burn at least a portion of the casing so that a portion of the mineral is fused, and a beaded weld formed along the back as well as and at the same time as on the front surface. Welding may thus be effected in positions other than horizontal. The flexible casing may consist of silk, cotton or wool or spun glass fabric so as to be combustible or fusible with the granular material which may consist of prefused silicates of alkaline earth metals together with calcium fluoride or manganese dioxide described in Specification 433,723. The operation may be effected by the electric arc with a bare or coated metal electrode or a carbon electrode or by gas or thermo-aluminic welding. The work parts may have bevelled or squared edges separated by a substantial gap. In Fig. 1, in which welding is effected by a bare metal electrode submerged under the surface of a flux of similar nature to that contained in the flexible casing C, the plates M rest on a troughed support 20 containing one or more layers of canvas 24 placed in a flexible tube 22, the edges of the canvas carrying metal blocks 26. The flexible casing C containing the granular material G is placed on the canvas and when the tube is inflated the blocks limit the expansion thereof and retain it centrally of and in tight engagement with the seam W. In modifications the casing may be placed on a spring-pressed plate or in a channelled member pierced against the seam by wedges. In a further modification, Fig. 5 the channelled member 42 is pressed against the seam by wedges 44 resting on an angle bar 40 welded to one of the plates. In another form, Fig. 8, in which the work M and casing C are traversed past the electrode E the casing C is carried by a reel R mounted on a support 50 from which it is unwound and pressed against the seam by a spring-pressed grooved roller 54 during traverse of the joint. In another form, Fig. 9, for making a circumferential weld on pipes, tanks or pressure vessels, a ring shaped casing C is mounted on arcuate channel members 72 carried by telescopic arms 74 from a hollow axle 76 through which fluid is passed to force the members 72 outwards so that the casing engages the back of the seam. In fillet welding, Fig. 1, the casing is held against the back of the weld by brackets 80 operated by springs, wedges or flexible pneumatic tubes. Specification 464,191 also is referred to

IPC: B01J31/02
Filed: 1950-02-06
Abstract: In the esterification of dicarboxylic acids with OXO alcohols, the colour-inhibitors of Specification 674,524 are replaced by phosphite esters.  Simple phosphites P(OR)3 may be used where R is aryl (e.g. phenyl or cresyl), aralkyl, cycloalkyl or alkyl, especially the same group as that of the alcohol being esterified; such esters are made by reacting the appropriate alcohol or phenol with phosphorus trichloride or tribromide. Also there may be used polyphosphite esters obtained from polyhydroxy compounds and phosphorus halides; preferably there is added to the reaction mixture a monohydroxy compound so that the product is a linear chain polymer and not cross-linked.  Partial esters of phosphorus acid are also applicable. The phosphite may be used in amounts of 0.1-5 per cent of the alcohol used and is preferably added to the alcohol before esterification. Examples show the esterification with phthalic anhydride of C6 alcohols derived from C3-C4 olefines by condensation and oxonation. The colour-inhibitors used are (1) triphenyl phosphite, (2) tricresyl phosphite, (3) trioctyl phosphite corresponding to the alcohol being esterified, (4) a polyphosphite obtained from 4-phenylphenol, 2 : 5 - di - tert. - butyl - hydroquinone and phosphorus trichloride (formula given) and (5) as in (4) using instead of 4-phenylphenol 1-phenyl - 1 - (p - hydroxyphenyl) - ethane (formula of product given).

Title: Improved process of hydrolysing cellulose acetate
IPC: C08B3/24
Filed: 1937-02-03
Abstract: Cellulose acetates, or mixed cellulose esters whose acyl content is mainly acetyl, are hydrolyzed in solution under conditions which avoid gelling and degradation, until the acyl content is reduced to 28--24 per cent, 24--19 per cent or 19--13 per cent.  The hydrolysis is effected by the addition of substantial quantities of sulphuric acid and of water, and the water is added gradually, or the temperature is kept high, or the water is added in the form of aqueous acetic acid, so as to prevent gelling.  The minimum amount of water required is 15 per cent of the bath for hydrolysis to the 28--24 per cent range, 20 per cent for the 24--19 per cent range, or 25--30 per cent for the 19--13 per cent range of acyl content. Cellulose acetate, e.g. of 30 to 40 per cent acetyl content may be dissolved in 50 to 60 per cent acetic acid containing sulphuric acid catalyst and maintained at 100 DEG  F. until the desired product is obtained.  Examples are given.  The esters having an acetyl content of 24--28 per cent may be formed into film and this film may be overcoated with a solution of a cellulose derivative in acetone, this layer being afterwards removed if desired without injury to the base film. The non-watersoluble but water-susceptible cellulose acetates having an acetyl content of 19 to 24 or 26 per cent may be used as carriers for light sensitive substances, e.g. silver salts, employed in the manufacture of photographic film.  Hydrolyzed cellulose acetates having an acetyl content of 13 to 19 per cent may be used as stripping layers, or as emulsifying agents, e.g. for benzene and paraffin oil.
