Title: Improvements in or relating to thermally operated electric switches
IPC: H01H37/56
Filed: 1953-06-10
Abstract: 756,858. Thermal switches. PARSONAGE, S. H. Sept. 9, 1954 [June 10, 1953], No. 15969/53. Class 38(5) A cycling switch has a bimetal element which controls an armature carrying or forming two contacts movable between a pair of spaced fixed contacts, engagement of one of which closes an energizing circuit for the bimetal and engagement of the other of which closes a load circuit, only. The bimetal element 21 is attached to a shaft 20 and has a rod 23 carrying the armature 24. The latter carries mutually insulated contacts 25, 26 respectively cooperating with contacts 5, 15, the. contact 5 being associated with a magnet 6. Contact 15 is carried by an arm 13 mounted cbaxially, with shaft 20 and is. biased against an adjusting cam 16 by a spring 17. Contacts 5, 26 are connected to a terminal 4 and contacts 15, 25 to a terminal 7. The arrangement is such that the contacts 5, 25 are normally closed to heat the bimetal 21 (by the current through it, or by a heating coil, not shown). Eventually these contacts snap apart and contacts 15, 26 close to complete a load circuit. The bimetal then cools and recloses contacts 5, 25 to restart the cycle. Ambient temperature compensation is given by a further bimetal element 22 wound in the same direction as element 21 and connected to the shaft 20 and having its outer end adjustably secured to a frame 29 by a nut 27. In a modification, Fig. 7, the element 22 is wound in the opposite direction to element 21 and its inner end is attached to a fixed shaft 35 coaxial with the shaft 20, the outer end of the element 22 being connected by link 39 to the shaft 20. The shaft 35 is adjustably secured in 'position by a screw 36. Contact 25 is preferably a silver button on a mild steel member. The contact 15 :is.-continuously adjustable by the cam 16, but may be adjusted through a series of predetermined positions. Instead of being spirally-formed the elements 21, 22 may be straight or helically formed, and the compensating element may be secured to one .end of, and reversed with respect to, the element 21.

Title: A process for the manufacture of resinous condensation products
IPC: C08G8/28
Filed: 1936-06-08
Abstract: In the production of resinous condensation products from substituted phenols and aldehydes according to the process described in Specification 459,459, there is used in addition to, or instead of, the terpene halides used in the preparation of the substituted phenol, halides prepared from technical alicyclic hydrocarbons or corresponding mixtures of saturated or unsaturated character which are oxygen-free or contain hydroxyl groups (other than terpenes, sesquiterpenes or polyterpenes) or acyclic compounds of genetically kindred substances such as olefinic terpenes, terpinogens, or compounds of undetermined structure obtained by simple treatment, such as heating, from high molecular weight substances such as natural resins.  Suitable substances to be converted into halides include hexahydrotoluene, hexahydroxylene, decahydronaphthalene (which may occur in petroleums rich in naphthenes), brown-coal tar and mineral-coal tar distillation products, geraniol, isoprene, copal oils and tall oils.  The halides may be prepared by substitution with halogen, addition of halogen or hydrogen halide, or by esterification of hydroxyl groups.  Excess free phenol present in the substituted phenol prepared may be removed or converted into other substituted phenols.  In examples: (1) a benzine fraction is chlorinated and condensed with phenol in the presence of zinc chloride; (2) geraniol is treated with gaseous hydrogen chloride and the product condensed with phenol in the presence of zinc chloride; (5) Congo copal oil and phenol are reacted in the presence of hydrogen chloride and zinc chloride; (6) isoprene and phenol are reacted in the presence of hydrogen chloride and aluminium chloride; and in all cases the products are reacted with aqueous formaldehyde or paraformaldehyde. The Specification as open to inspection under Sect. 91 refers also to the use of halides of terpenes, sesquiterpenes and polyterpenes and substances resembling terpenes such as menthane, pinane, cedrene, cadine, terpinhydrate, turpentine oils, pine oils, colophony, tallow oils, borneol, menthol, terpin, and terpineol. Examples illustrate the use of American pine oil, abietic acid, dipentene and cumin oil in the manufacture of the substituted phenol.  This subject-matter does not appear in the Specification as accepted.
