Title: Improvements in or relating to electric fan heaters
Inventor: BATES ROY STANLEY
IPC: F24H3/04
Filed: 1958-09-16
Abstract: 873,047. Electric fan heaters. GENERAL ELECTRIC CO. Ltd. July 21, 1959 [Sept. 16, 1958], No. 29650/58. Class 39(3). In an electric fan heater an auxiliary heating element 11, Fig. 3, may be connected in series with the main heating element 10 to give a lower degree of heating. The auxiliary heating element is of substantially thinner gauge wire and may thus be made shorter than element 10. A safety switch device 12 comprises a thermostatic disc switch 13 which opens the heater circuit when the air stream fails. When switch 20 is closed heating of the disc is effected only from the 2 kw heating element 10, but when switch 20 is opened putting elements 10 and 11 in series energy is dissipated at 1 kw and an additional series heater 17 is provided to heat the disc in order to compensate for the reduced energy dissipation element 10. The elements 10, 11, Fig. 2, are arranged on a support as shown, the auxiliary element 11 being disposed in the region where the air flow through the device is relatively slow. The device may have more than one auxiliary element, and a switch may be provided so that the device produces a cooling air stream by cutting out of circuit all the heating elements. The elements 10, 11 are of nickel-chrome alloy and support on insulating members (not shown).

Title: Improvements in radiation measurement of transparent bodies
IPC: G01J5/60
Filed: 1950-12-06
Abstract: 699,963. Colour filters. LEEDS & NORTHRUP CO. Dec. 6, 1950 [Dec. 6, 1949], No. 29894/50. Drawings to Specification. Class 97 (i). [Also in Groups XI and XL (b)] For measuring the temperature of glass and like materials which have a very low reflectivity and transmissivity in the range of wavelengths 3 microns to 8 microns, a filter is interposed between the radiation receiving element of the pyrometer and the material to reduce errors due to reflected or transmitted radiation. The filter may be a one-millimetre thickness of lithium fluoride to pass radiation below about ten microns and at least one face is coated with silica or quartz flour having particle sizes 3 to 6 microns to restrict radiation to a band of wavelengths 3 to 8 microns. An additional filter of mica, sapphire, or an 8-millimetre thickness of lithium fluoride may be utilized to restrict the upper limit to 7 microns or the coating may be added to such filter. The coating is formed by suspending silica flour and a silicone in methyl ethyl ketone, applying to the surface of the filter, drying at a low evaporation rate and then baking. By reducing the particle size of the silica flour the filter cut-off may be reduced from 3.8 to 3 microns. In a modification calcium fluoride having a coating of finely ground bentonite or other clays having particle sizes between about 3 and 6 microns are used. The filter surface may be polished or sand blasted for greater adherence of the coating.
Patent GB-717956-A (GB)
Title: Improvements in or relating to a device for dispensing pressure-sensitive adhesive tape
IPC: B65H35/00
Filed: 1952-11-26
Abstract: 717,956. Tape dispensers. DERBY SEALERS, Inc. Nov. 26, 1952, [Dec. 8, 1951.] No. 29936/52. Class 18. In an apparatus for dispensing pressuresensitive adhesive tape, operation of a crank or lever rotates a feed roll consisting of a plurality of spaced discs 12 on a shaft 13, Fig. 4, to feed the tape 30 from the tape roll to a stripper roll consisting of a plurality of discs 14 on a shaft 15. The discs 14, which are provided with teeth 16 so as to lessen the area of contact with the tape, extend between the discs 12, and the stripper roll is driven by gearing at a greater peripheral speed than the feed roll. To prevent the tape from being drawn between the feed roll and the driving roll, and the free end of the tape from curling, a flat spring-like member 31 is secured to the knife 32 and presses the tape against the stripper elements 14. The member 31 also acts to strip the end of the tape from the knife after the severing operation. The knife is mounted on a removable support 33, Fig. 6, which is received in recesses 39 in the casing, the support 33 having its corners cut away as at 38. Plates 40 having lugs 42 and 43 are secured to the walls of the casing together with wire spring members 45 whose lower ends 46 are arranged at a level slightly above the lower ends of the recesses 39. To mount the knife support it is turned at an angle and its lower edge inserted behind the lugs 43, and it is pressed downwardly so that the notches 38 will pass the lugs 42. Upward pressure of the springs 45 will then hold the knife support in place.. The knife and the knife support may be formed as one integral part, and the cutting edge may be sharpened instead of serrated. A screw may be provided for adjusting the pressure of the spring member 31 on the stripper roll. In a modification, Fig. 12, the cutter member is secured at each end to lugs 53 provided upon the side walls. The knife 54, which has a serrated edge 55, is secured to a plate 56 by means of screws 57, a coil spring 58 being compressed between the head of the screw and the plate 56 so that the knife 54 is resiliently urged towards the stripper elements 14. In Fig. 13 (not shown) an additional knife having a smooth sharpened cutting edge is secured in front of the plate 56, and by this means the tape may be cut upon the sharp edge, and the serrated edge will prevent slipping of the tape to one side. In a further modification, the feed roll and the stripping roll, which may be solid rolls or made up of spaced discs, are spaced apart instead of being intermeshed. Specification 717,955 is referred to.

Title: Polymers of fluorinated organic compounds
Inventor: HASZELDINE ROBERT NEVILLE
IPC: C08G73/26
Filed: 1958-09-22
Abstract: A perfluorinated nitrosoalkane (RNO) and hexafluoropropylene are copolymerized at at least 50 DEG C. and 30 atmospheres absolute to yield a copolymer having repeating units of the structure <FORM:0901206/IV(a)/1> where R is a perfluoroalkyl group and X is F and Y is CF, or vice versa.  It is preferred to use equimolar proportions of the monomers, which proportion is found in the product regardless of the initial proportions of the reactants.  In the specific example trifluoronitrosomethane is used.  The copolymer products range from oils to waxes and elastomeric gels and are insoluble in water and common organic solvents.  They may be used as coolants, heat transfer media, coating and sealing compositions, flexible hosing and lubricants, especially under chemically corrosive conditions.ALSO:Polymers comprising structural units of the formula <FORM:0901206/IV (b)/1> where R is a perfluoroalkyl group and X is F and Y is CF3 or vice versa are obtained by heating hexafluoropropylene with a perfluoronitrosoalkane under pressure.  To obtain high polymers (see Group IV(a)) the minimum pressure is 30 atmospheres absolute.  At pressures up to 60 atmospheres a temperature of 100 DEG C. is needed; above 60 atmospheres the minimum temperature is 50 DEG C.
