Title: Improvements in or relating to the method of burning granular fuel
IPC: C21B5/00
Filed: 1955-04-20
Abstract: 772,072. Combustion apparatus. COMBUSTION ENGINEERING, Inc. April 20, 1955 [April 26, 1954], No. 11391/55. Class 51 (1). In order that a granular fuel of large particle size and low volatile content, e.g. char from low-temperature carbonization of coal utilizing the fluidized process or coke produced by the oil cracking processes which use fluidized coke beds, may be burnt in suspension it is simultaneously introduced into a furnace with a fuel which is capable of self-sustaining ignition such that a portion of it is burnt, the unburnt portion that passes from the furnace entrained in the combustion gases being collected and then pulverized such that it may be reintroduced into the furnace generally at the location of the burning fuel. In the furnace shown burners 16, 18, 20 project fuel and air in a tangential manner into a chamber 10 from which molten ash is continually drawn off through an opening 13 whilst the hot combustion gases, together. with entrained solids, pass via superheater 30, economizer 33, air heater 34, dust collector 28 to a chimney and hence into the atmosphere. Each of the burners is supplied with heated air from the air heater 34 through a duct 14 and together with this air burners 18 fire large particle sized, and low volatile content fuel whilst simultaneously burners 16 fire a gaseous fuel or other fuel capable of self-sustaining ignition with suspension firing. The unburnt fuel in the combustion gases is deposited partly in a hopper 36 and partly in a hopper 38 connected to the dust collector. The fuel so deposited is passed through pipe 40 to a pulverizing mill 42 which receives its carrier gas a mixture of air from the air heater and combustion gas from the chimney through ducting 41. The pulverized resultant entrained in the carrier gas is then passed to the burners 20 through ducting 44.

[Classes 38 (iii) and 38 (v)] A hand-operated controller adapted also to effect magnetic braking is arranged to be actuated by a single hand of an operator and ensure that the motor is disconnected from the supply before the braking circuit is established, a returning spring being provided to open the braking circuit immediately the manual control is released. The control device may comprise a lever movable in two-planes at right angles, a rotary lever movable over a pair of concentric arcuate contacts, a push-button system, or a rotary lever provided also with a push-button in the operating handle. Fig. 1 shows an arrangement wherein a reversible motor 4 has a conventional drum controller rotatable about an axis 13 by corresponding movement of a lever 15 which can also be swung inwardly about an axis 12 at right angles to axis 13. A contact plate 16 pivoted on the lever 15 and insulated therefrom bridges two concentric arcuate or ring conductors 17, 18 when the lever 15 is pushed inwardly, so that when the drum is in an intermediate or neutral position with its studs M and M1 disconnected from the contact fingers 22, and the fingers 8, 9 in contact with a contact plate 10, the contact plate 16 completes the circuit of the braking coil 35 between phase tappings 24, 23. In a modification, Fig. 3, the starting and reversing lever 15 is limited to an arcuate movement about the drum controller axis and braking is effected by operation of a push-button 31 in the handle 11 after bringing the lever 15 to the intermediate or neutral position, the push-button contact being depressed on to contacts connected respectively to points 36, 37 in the electromagnetic brake circuit, as indicated by the broken lines between Figs. 1 and 3. In a further modification, the manual control is exercised entirely through push-buttons which control auxiliary circuits whereby an A.C. motor is started by star-delta coupling, variation of rotor resistance, or any other method. Three pushbuttons are arranged in close alignment, the outer ones being for " forward " and " reverse " operation respectively, while the intermediate one, Fig. 5 (not shown), has normally closed contacts 56, 57 in a common return line, these being controlled by a central push-button49, and normally open contacts 53, 54 which are connected in the electromagnetic braking circuit and operated by depression of an outer sleeve 50 which moves together with 49 after the latter has opened contacts 56, 57. Fig. 10 shows a modification comprising a metal disc 69 urged normally against an upper pair of contacts 67, 68 by a spring 61, and provided with a push-button 64 whereby it can be depressed on to a pair of contacts 65, 66 (the latter not shown) on a diameter at right angles to the upper pair and connected to the braking circuit.
Patent GB-570992-A (GB)
Title: Improvements in the manufacture of metal hypochlorites
IPC: C01B11/06
Filed: 1943-07-20
Abstract: In the production of metal, e.g. calcium, hypochlorites, by reacting the corresponding alkali or alkaline earth metal oxide or hydroxide with an alkyl hypochlorite in the presence of water, the oxide or hydroxide is admixed with about one to four times its weight of water and the resulting mixture is then mixed with alkyl hypochlorite in excess of the amount required to form the neutral metal hypochlorite. The corresponding alcohol is also produced in the process.  A tertiary alkyl hypochlorite such as tertiary butyl hypochlorite is preferably employed.  The process may be employed in carrying out the third step of a cyclic process in which (1) an alcohol is reacted with aqueous hypochlorous acid, or with chlorine and sodium or calcium hydroxide in the presence of water to produce an alkyl hypochlorite; (2) the alkyl hypochlorite is separated from the aqueous phase; and (3) the separated alkyl hypochlorite is reacted with the metal oxide or hydroxide to form the corresponding metal hypochlorite and alcohol which is returned to the first step of the process, as described in U.S.A.

Abstract: 697,044. Moulding liquid filled rubber containers. POLLITT, D. H., and HAWE, P. G. May 22, 1951. No. 11912/51. Class 87 (ii). A container such as a centre for a golf ball is formed by feeding two strips of plastic material, e.g. unvulcanized rubber 30, between corresponding rollers 8, 18 rotatably mounted in a liquid receptacle 7. The rollers are driven in the directions of the arrows by interengaging gearing, (see Fig. 3, not shown). Male members 19 force the strips into cavities 10, and as the rollers 8 come into engagement, rims 31 seal the strips together to form the completed container. The strips are prevented from creeping on the'rollers 8 by the interengagement of ribs 11 and rolling surfaces 26. To allow the liquid to enter into a cavity as a male member is leaving it and thus prevent the formation of a vacuum which might unseat the strip, the male members are each provided with a central hole 22, Fig. 5, connected to the liquid by a passage 21.
