Title: Improvements in or in connection with gas cooking stoves
IPC: F24C15/10
Filed: 1923-10-20
Abstract: 227,535. Flavel, P. W. Oct. 20, 1923. Gas cooking-stoves; hot-plates. - The gas burners G project through openings in the hotplate A, utensils being supported above them on studs F attached to or forming part of the plate. The burners are a close fit in the apertures, the air supply to them travelling over the surface of the plate and being preheated by downward radiation from the flames spreading over the bottom of the vessel. The studs F have rounded surfaces and in the form shown ceramic liners are placed between them and the plate, in order to prevent conduction of heat. The tap-rail L may be cast with the plate. The griller, Fig. 5, is formed by raised bars having lugs J engaging notches at the sides of an aperture in the hotplate, or by a raised cover held in a similar way over the aperture.

Title: Method for converting anion exchange resins from the monovalent anion to the hydroxide form
IPC: B01J49/00
Filed: 1971-04-19
Abstract: 1339788 Converting anion exchange resins ECODYNE CORP 19 April 1971 [20 April 1970] 26264/71 Heading C3P [Also in Division B1 A strong-base anion exchange resin having quaternary ammonium active groups is converted from the monovalent anion form (other than hydroxide) to the hydroxide form by passing an aqueous source of polyvalent anions through a first batch of the resin to displace monovalent anions from the resin with the polyvalent anions; subsequently passing an aqueous solution of alkali metal hydroxide through the resin to convert the resin to the hydroxide form, and to produce an aqueous effluent solution containing hydroxide anions and polyvalent anions; neutralizing at least a portion of the effluent solution with an acid containing a source of the polyvalent anions to form a neutralized source of polyvalent anions; and passing the neutralized source through a second batch of the resin in the monovalent anion form to displace the monovalent - anions therefrom. The "monovalent anion form" means a resin form other than the hydroxide form. The "neutralized source" is merely more acidic than the effluent solution and may be acidic, neutral or even basic. Suitable resins are those prepared by reacting a tertiary amine with a halomethylated cross-linked copolymer of a monovinyl aromatic hydrocarbon and a divinyl aromatic hydrocarbon, e.g. a copolymer of styrene and divinylbenzene with or without ethylvinylbenzene. Other suitable resins are the reaction products of a tertiary amine with a haloalkylated, preferably chloromethylated, copolymer of a vinyl aromatic compound, e.g. styrene or vinylanisole and a minor proportion of a polyolefinic compound, e.g. divinyl benzene, isoprene, butadiene or trivinylbenzene. In the example sodium hydroxide, sodium sulphate and sulphuric acid are used.

Abstract: 368,771. Electric clocks. HAMMOND CLOCK CO., 2915, North Western Avenue, Chicago, U.S.A.-(Assignees of Hammond, L. ; 1390, Scott Avenue, Winnetka, Illinois, U.S.A.) Sept. 4, 1930, No. 26391. Convention date, Sept. 5, 1929. [Class 139.] The polepieces and rotor of a synchronous motor of the unwound iron armature type for driving clocks &c. are enclosed in a casing detachably secured to a plate which carries the field-magnet and the gear train. The fieldmagnet 62 is mounted in a gap 61 in a plate 60 of magnetic material to which the ends of the core 64 are secured. Part of the flux is byepassed by portions of the plate 60 left for the purpose, the remainder passing through the wall of the casing 68 to the laminated polepieces 104, 106. These are toothed and between them is mounted the toothed rotor 112, the polepieces being so shaped that the resultant force on the rotor acts upwards, thus diminishing the load on the bearings and consequent friction. In addition to the polepieces and rotor the casing 68 contains a pinion 130 on the rotor spindle gearing with a pinion 136 on a spindle 138 which passes outside the casing where it carries a pinion 40 meshing with the gear-train of the clock. To prevent lubricant from escaping from the casing 68 the spindle 138 is surrounded by a trunk 144, close to the end of which is a plate 148 with a capillary channel 146 for collecting and removing any oil which mav enter the trunk. The rotor 112 is mounted on a hub 114 running loose on the spindle 120 and the pinion 130 is fitted into a socket in the hub. This socket is such size that the pinion 130 has to be turned nearly but not quite down to the roots of the teeth to fit it, thus forming a number of capillary lubricating channels. On the hub 114 are loosely mounted a number of rings 124, serving as an inertia governor to maintain the motor at synchronous speed over temporary interruptions of the current &c.

Title: Fuses for projectiles
IPC: F42C9/12
Filed: 1924-05-26
Abstract: 241,941. Pantoflicek, B. May 26, 1923, [Convention date]. Projectile fuzes.-Relates to percussion fuzes which are armed after a given time determined by the combustion of a time fuze composition ignited when the projectile is discharged. According to the invention, the composition 31 is arranged in a time ring 30 and the firing member (not shown) is so arranged that in its movement on impact it neither passes nor forces any other member into space previously occupied by powder. When the composition 31 burns to its end 37, it releases a centrifugal bolt 35, which moves radially out and unlocks the striker of the percussion fuze. In a modification, a fusible metal plug is inserted between the end 37 of the fuze composition and the head of the bolt 35. In another modification, the striker is locked by a member of fusible material which is melted by the flash from the end of the fuze composition.
