Title: Improvements in and relating to electric hot plates
IPC: H05B3/76
Filed: 1948-11-04
Abstract: 661,675. Electric hot plates. BRITISH THOMSON-HOUSTON CO., Ltd. Nov 4, 1948. [Nov. 4, 1947; Nov. 4, 1947] Nos. 28695/48 and 28696/48. Class 39(iii). An electric hot plate comprises a sheathed resistance heater arranged in a series of flat, spiral or annular turns such that each turn is spaced radially from its adjacent turn and the space between adjacent turns, for any cross-section through the hot plate, increases progressively throughout the unit from the outermost to the innermost turn. In the construction described, Fig. 1, the heating element comprises an outer and an inner spiral 8 and 9 respectively. Alternatively, a single or a plurality of spirals, interlocked if desired, or concentric circular or partially circular turns may be used. The turns are flattened on their upper surfaces and the spacing between them preferably does not exceed their cross-sectional diameter which may be 0.270 inches. The turns rest upon several radially extending arms 5, 6 and 7, Figs. 1 and 2, supported by a flanged trim ring 4, the arms having lugs 17 to 20 wherein the elements are rigidly or slidably secured. Any single element is secured in this manner not oftener than every alternate arm along its length and any single arm has these securing points not oftener than every alternate element disposed across it. The ring 4, arms 5 to 7, and the heater coils 8 and 9 may be hinged and grounded to the cooker top as at 21, Fig. 2. The hinge comprises a bracket 22, Figs. 2 and 3, adjustably secured to the cooker top, with a hinge pin 23 from which extends a flexible and resilient terminal shield 24 around the heating element ends. A flexible resilient grounding strap 29 connects the bracket 22 to the terminal shield 24. In the preferred example the terminal shield has flanged rings 35 in which the ends 31 of the outer spiral 8 may slide upon expansion or contraction. The ends 30 of the inner spiral are firmly secured to the shield, however, but the shield is slotted as at 38 to facilitate the thermal movements of these ends. A heat reflecting drip pan 39 is below the heating elements. Specification 144,767, [Class 39(iii)], is re- 'ferred to.

Title: Synthetic crystalline zeolites
IPC: C01B39/02
Filed: 1958-09-17
Abstract: A synthetic zeolitic aluminosilicate molecular sieve of formula <FORM:0896784/III/1> where X is from 0 to 1,4, designated zeolite J, having a characteristic X-ray diffraction pattern, wherein M is a K, Na, Ag, Ca hydrogen or ammonium ion, is prepared by first forming the potassium zeolite concerned and forming the other isomorphs by ion exchange with the potassium form.  The latter may be prepared by heating a mixture having a mole ratio of oxides: K2O/SiO2 of 3,7 to 4, SiO2/Al2O3 of 4, and H2O/K2O of 9,7 to 10 at a temperature of about 100 DEG C.  Silica may be provided as silica gel, silicic acid or potassium silicate, alumina as activated, alpha or gamma alumina, alumina trihydrate, aluminium hydroxide or potassium aluminate and potassium hydroxide may supply the potassium ions. The reaction mixture, for example an aqueous solution of potassium aluminate and hydroxide and a solution of potassium silicate, may be mixed to ensure homogeneity and heated to 100 DEG C. to effect crystallization, and the crystals washed with distilled water p until the effluent wash has a pH of 9 to 12.  The zeolite may be activated by heating at 350 DEG C., or by maintaining at room temperature under vacuum, and may thereafter be used in a cyclic adsorption-desorption process particularly where the material adsorbed is water.  Reference is made to the separation of water from carbon dioxide or ethylene by means of this zeolite and to the adsorption of ammonia and sulphur dioxide.  The zeolite may be pelleted with a bonding agent such as clay.  In preparing isomorphs from the potassium form, the exchange solution preferably has a pH from 5 to 12.
Patent GB-1009305-A (GB)
Title: Cyclic vinyl boron compounds and their production
IPC: C08F30/06
Filed: 1962-08-02
Abstract: The invention comprises vinyldioxaborinanes of the formula <FORM:1009305/C2/1> where R is a 1,3-alkylene group containing from 4 to 20 carbon atoms.  These may be made by reacting a glycol monoborate ester of the formula <FORM:1009305/C2/2> where R1 is a lower alkyl group (i.e. containing 1 to 6 carbon atoms) or a phenyl group in which any substituents are lower alkyl groups, with a vinyl Grignard reagent of the formula CH2=CHMgX, where X is a chlorine or bromine atom, and heating the complex thus obtained to form the required vinyldioxaborinane.  In a preferred procedure, the reactants are introduced gradually in substantially equimolar proportions into a reaction zone containing ether as a solvent while a temperature of at most 25 DEG  C. is maintained in the zone; when all the reactants have been added the solvent is removed, the residue is distilled and the vinyldioxaborinane formed is separated from the distillate, e.g. by fractional distillation.  It is preferred to add an inert high boiling heat transfer medium, such as mineral oil, to the reaction mass after the etherial solvent has been removed to facilitate the pyrolysis and removal of the residual solid from the reaction vessel. Detailed examples describe the preparation of 2 - vinyl - 4,4,6 - trimethyl - 1,3,2 - dioxaborinane and 2-vinyl-4-methyl-1,3,2-dioxaborinane. The vinyldioxaborinanes can be homopolymerized or copolymerized with other vinyl monomers.  They may be reacted with halogens, Diels-Alder reagents or mercaptans to form substituted alkyldioxaborinanes useful as germicides, herbicides, insecticides and fungicides.
