Abstract: 628,755. Vulcanizing. STEINER, L. Nov. 15, 1946, No. 33964. [Class 70] [Also in Groups XI and XXIX] A pressure and heating element particularly for vulcanizing valves and like fittings into tyre tubes and the like, and for the repair of punctures close to such valves, has one wall formed externally as a pressure surface for the work to be vulcanized, said wall being heated by a flat electric resistance, and is provided with a passageway through the pressure surface wall and the casing of the element to enable the pressure surface to act around a valve stem or the like, the passageway being substantially surrounded by an electric resistance. A hollow metal casing 10, made in two parts 10a, 10b, is firmly secured to an arched bracket 11 having four spaced legs, two of them being 12, 13, the upper part of the bracket 11 being hollow underneath, and the bracket 11 being adapted to be secured at its top to the lower end of a pressure plunger forming part of the usual vulcanizing machine. The casing 10, which is heated by an electric resistance formed in two sections 24a and 24b contained in a housing 25 in the casing, has a central passageway 22 and underneath has a shallow concave zone 23 to provide for the graduated thickening of a tyre tube wall round the valve. This concave zone may, if desired, be formed in an intermediate plate formed separately from but secured to the pressure surface of the pressure and heating element. When the device is in use the valve stem of the tyre is passed through the passageway 22 as shown at 30 or 30a, the upper part 10b of the casing 10 being formed with grooves 32 to enable the device to take the type of stem shown by 30a. In a modification (Figs. 4, 5 not shown) the pressure and heating element is mounted by a tubular bracket member whose bore forms an extension of the passageway 22. The Specification (Fig. 6, not shown) describes an adapter for use with small valve seatings, comprising a metal annulus having a central hole whose upper surface is curved to fit within the concave zone 23 while its underneath is formed with a smaller concave zone to conform to the smaller valve seating. The Specification also describes a modification (Fig. 7, not shown) whereby the aperture in casing 10 is a notch extending into the side of the casing thus enabling the valve stem to be passed into position in a sideways direction, the lower surface of the casing being flat and an annular intermediate plate having a concave undersurface being placed over the valve stem before the stem is inserted into the notch.

Title: Process for the purification of ethylene glycol by distillation
Filed: 1954-11-24
Abstract: Ethylene glycol is purified by distilling it, preferably under reduced pressure, in the presence of sodium hypochlorite.  The purified glycol, when used to prepare aromatic linear polyesters, yields products having an improved colour compared with polyesters prepared from commercial grades of glycol.  In an example, 100 parts of commercial ethylene glycol are charged to a still; and 0.25 parts of caustic soda liquor together with 0.175 parts of an 8 per cent solution of sodium hypochlorite are added.  The still is put under an absolute pressure of 40 mm.  Hg and the charge is boiled under total reflux for half an hour.  Distillation is then effected using a reflux ratio of 4:1.  The colour of the distilled glycol is much brighter than that of the original commercial glycol.ALSO:Ethylene glycol is purified by distilling it, preferably under reduced pressure, in the presence of sodium hypochlorite.

Title: Prevention of harmful effects of steam decomposition in steam generating plants
IPC: F22D11/00
Filed: 1958-10-29
Abstract: 845,342. Preventing corrosion. SULZER FRERES S. A. Oct. 29, 1958 [Feb. 4, 1958], No. 34725/58. Class 123(1) [Also in Group XIII] In a steam power plant including a boiler generating steam at high pressure and temperature, especially a supercritical boiler, oxygen corrosion of pipelines, valves, turbines, &c., due to steam decomposition is reduced or prevented by artificially increasing the hydrogen content of the working medium. In the plant shown a once-through boiler 1 having a preheater 2, evaporating section 3 and superheater 4 supplies steam to a H.P. turbine 6. After reheating at 8, the steam flows through an L.P. turbine 9 and exhausts into a condenser 10. Condensate flows through a degasser 12 into a hot well 13. Feedwater is drawn from the hot well through a preheater 15 by a pump 16 and fed to the boiler. A storage vessel 17 for hydrogen is connected to a valved distribution line 18 whence pipes 20, 21, 24, 26, 28, 30, 32 lead respectively to the inlet of the heater 15, the inlet and outlet of the pump 16, the inlet and outlet of the evaporating section 3, the inlet of the reheater and the hot well. In general hydrogen is supplied to only one of the points in the water or steam flow, for example, after the main feed pump, the amount being regulated according to the hydrogen content of the feed water to maintain a predetermined concentration. In the degassing device 12 the condensate is partially degassed by physical or chemical means so that all of the dissolved oxygen and sufficient of the dissolved hydrogen to leave the required amount in the condensate passing to the hot well are removed, only very small amounts of hydrogen then being required to be added artificially.

Title: Latch device for nuclear fuel
IPC: G21C19/02
Filed: 1965-08-13
Abstract: 1,059,195. Fuel elements. - ATOMIC ENERGY OF CANADA Ltd. Aug. 13, 1965 [Sept. 30, 1964], No. 34795/65. Heading G6C. A latch device for releasably connecting endto-end fuel sections of a fuel rod assembly comprises (Fig. 1, not shown) an elongated spindle (10) having a base portion (11a) from which a number of collet fingers (11) project in parallel relation surrounding the spindle (10), and means for mounting the base portion (11a) on an end of a first fuel section (20) (Fig. 4, not shown) to project radially therefrom, the fingers (11) having outwardly facing latching flanges (12) on their free ends for engagement with an inwardly projecting lip (27) surrounding a cavity (26) in an end of a second fuel section (25) and being mounted for radially inward resilient compression for release of the flanges (12) from the lip (27). The latch device is attached to one end of the fuel section (20) by a nut (17) threaded on an end portion (16) of the spindle (10) behind a portion (23) of the end support member (22) of the fuel section. The portion (16) terminates in an alignment pin (18) which enters a guiding cavity (24) in the central fuel bar. The collet fingers (11) move to the locking position due to their inherent resilience, surfaces (13) serving to spring the fingers (11) inwards as they pass the lip (27) during inward motion. When the fuel sections are pushed together the end members (22) abut one another with the device entering the cavity (26). They can be moved apart until the lip (27) and the flanges (12) engage, after which tension is transmitted from section to section so that withdrawal of one of the fuel sections from a reactor tube causes the other sections to follow. When it is desired to release one fuel section from the next, the assembly is mounted in an unlatching mechanism which includes jaws that can be brought together to compress the collet fingers (11) and thus release the latching engagement of the flanges (12) with the lip (27). Fins (15) mounted on the free end of the spindle (10) serve to limit the inward deflection of the fingers (11).

Title: Improvements in or relating to means for controlling the travel of webs of paper or the like
IPC: B65H23/032
Filed: 1934-12-06
Abstract: 435,899. Feeding webs. JAGENBERG, G. MEYER-, 107, Himmelgeisterstrasse, D³sseldorf, Germany. Dec. 6, 1934, No. 35117. [Class 100 (i)] In controlling the travel of a web of paper or the like by an electric circuit the condition of which is dependent on the travel of the side edge of the web, current variation is caused to change the speed of one or both of two motors continuously rotating and controlling the travel of the web. The motors may act upon the roll being wound or unwound through a mechanical differential gear, one element of which is connected to the roll, or two motors may be arranged so that the shaft of one is normally stationary but is caused to turn and shift the roll by the speed variation of one of them. As shown in Figs. 1 and 2, two motors M1, M2 constantly run at the same speed and in the same direction when the run of the edge of the web T is correct, so that a crank 5 operating a rodadjusting screw is stationary. When the web shifts laterally a light sensitive cell Z, normally half illuminated causes an increase or decrease of current in the field winding d of the motor M1 and the crank 5 is suitably moved to correct the run of the web. In a modification two motors drive in opposite directions and at the same speed, two worms in mesh with a wheel which is coupled to roll adjusting means. The cell Z is in series with a field winding on each motor so arranged that one motor increases and the other decreases its speed when the web shifts. A slide in which the wheel is mounted is thus moved in a direction to correct the web position. Additional field windings in the motors are respectively energized by switches closed when the slide approaches the limit of its travel so that the motor speed is altered and the movement of the slide stopped. In further modifications, Figs. 8 and 9, the motors run in opposite directions at equal speeds in normal circumstances and the armature of one is arranged to rotate with the field of the other so that a shaft W coupled to the roll-adjusting means is then stationary.
