Title: Improvements in or relating to the dry cooling of enamel
IPC: C23D1/02
Filed: 1935-10-10
Abstract: 453,029. E n a m e l s. FIRMITANA METALLKERAMIK GES., 16, Hartmannstrasse, Bayreuth, Germany. Oct. 10, 1935, No. 27941. Convention date, Oct. 10, 1934. Drawings to Specification. [Class 56] A method of cooling enamel, after it has been melted, consists in flowing the moltan material into the pass between a pair of rollers by which it is formed into thin strips or flakes that are collected in a suitable vessel where they continue to cool slowly. The rollers are watercooled and are driven in opposite directions at the same or at different speeds. The rollers are pressed towards one another resiliently in order to prevent damage when hard lumps pass between them. The rollers may be moved to-and-fro, in the direction of their axes, below the outlet of the furnace in order to distribute the flowing enamel along the pass. Crushing-rollers may be arranged below the flattening rollers to pulverize the cooled enamel.

Abstract: 408,977. Rotary percussive drills. CROFTON & CO. (ENGINEERS), Ltd., C., and CROFTON, H. B., 11, Marden Road South, Whitley Bay, Northumberland. Oct. 17, 1932, No. 29017. [Class 124.] In a portable drilling-machine wherein the drill is reciprocated as well as being given a continuous rotation, the drive is transmitted to the drill through an accumulator or energy storing device such as a spring. As applied to a coal drill, a pinion 7 on the shaft 8 of an electric motor drives two planet pinions 10 mounted on a spider 12 and meshing with an internally toothed gear on a stationary sleeve 11. The motor is preferably a high frequency, high speed motor, e.g. a three phase squirrel cage motor running at 9000 r.p.m. supplied with power at 150 cycles by means of a frequency changer external to the machine. A pinion 14 on the spider 12 drives four planet pinions 15 mounted on a spider 16 and meshing with a second internal gear on the sleeve 11. A shaft 17 on the spider 16 drives the drill socket 2 through a spring 6 which is positively attached at 6<a>, 6b, to sleeves 20, 21 on the shaft and socket respectively. A cam ring 3 on the socket, having two diametrically offered rises, is adapted to engage two rollers 4 mounted on a stationary ring 5<a> so as to reciprocate the drill during its rotation, the construction being such that should the drill meet undue obstruction the spring 6 will yield, thereby storing up rotational energy to overcome the resistance and also allowing the cam 3 to engage more deeply with the rollers 4 to increase the amplitude of reciprocation. The rollers and cam surfaces are normally out of contact with each other and are formed conical to preserve line contact between them when they engage. Lugs 9<a>, 9<b> on the casing 9 support the feeding gear, which is described in Specification 409,234, [Group XXII].

Title: Heat treatment of agglomerated fuels
IPC: F28C3/16
Filed: 1961-08-11
Abstract: In a process of heat-treatment of briquettes and other agglomerated fuels by transporting them in a hot horizontally moving fluidized bed of sand or the like the bed is fluidized for short periods only and remains unfluidized, but heated, for longer periods.  Preferably the bed is divided longitudinally into two or more parts which are fluidized in succession.  As shown the bed material is separated into two parts 2, 3 by a central longitudinal partition in the treatment chamber, each part being supported on a slightly inclined porous slab or grid.  Briquettes &c. are delivered to both parts by a common shoot.  Hot air is supplied by a blower to ducts 4, 5, each furnished with a line of delivery nozzles beneath the beds.  The supply is controlled to provide a fluidizing blast to each of the ducts 4, 5, in succession for short periods (1-5 seconds) with intervening longer periods ( 1/2 -2 minutes) during which a <PICT:0971216/C4-C5/1> milder blast which aerates but does not fluidize the beds, passes through both ducts. At the end of the treatment chamber the bed material falls on a sieve through which it passes, the treated briquettes &c. being retained and delivered to a conveyer.  The sieved material is passed by fluidization into a chamber 10 whence it is reheated and elevated through tubes 14 by air supplied by a blower and containing entrained gaseous or vaporous fuel which is burnt in a combustion chamber 13.  Gases not required for elevation are by-passed through valved tubes 15.  The entrance to chamber 13 contains a stack of closely spaced plates to prevent the flame from blowing back to the blower. The elevated material falls at 18 on to a porous base inclined in the opposite sense to those at 2, 3, and is conveyed by fluidizing medium in a duct 19 back to the beginning of the circuit.  The gases used pass out through cyclones 17 which return any entrained bed material to the circuit.  In most cases a temperature of the sand at the inlet end of the treatment chamber of 350 DEG -400 DEG  C. and at the outlet end of 300 DEG -350 DEG  C. is preferred.

[Class 78 (i)] [See also Group XVIII] Apparatus for filling bags or the like with measured quantities of fluent material such as tea or coffee comprises a main receptacle or hopper 22, a measuring device 25 and means 23, 24 in which a predetermined quantity of material is maintained, for directing the material from the receptacle into the measuring device. The apparatus is supported on a frame 20, Fig. 1, within which a power shaft 21 is journalled. Material in the hopper 22 is agitated by a stirrer 28, Fig. 2, driven by a ratchet wheel 30 actuated by a pawl 31 mounted on a bell-crank lever 32 connected bv a link 35 to a lever 36 rocked by an arm 39 having at one end a roller which engages a cam 41 mounted on the shaft 21. Material is fed from the hopper 22 to the directing means comprising an intermediate hopper 23 and a flexible channel 24 by an endless belt conveyer 44 driven from a ratchet wheel 46<1>, Fig. 4, which is held from backward rotation by a pawl 47 and driven forwardly by a pawl 48. In order to keep a certain amount of material within the hopper 23, the pawl 48 is adjusted relatively to the ratchet by means of a link 51 and a member 52 which passes through a flange 55 on a measuring rod 56. By means of another flange 57 engaged by an oscillating arm 85, driven from the cam 41 the rod is repeatedly raised and allowed to fall back on to the surface of the material in the hopper 23. A toothed wheel 64 and a vertically oscillating plate 59 serve to prevent clogging of the material at the discharge end of the belt 44. The lower converging walls of the hopper 23 are provided on one side with a slidable bar 58 actuated through a link 78 from a cam 83 on the shaft 21 and on the other side with a swinging bar 70 operated from the arm 39 by links 71 and 73 and provided with an arcuate extension 72 adapted to close the hopper outlet when the bar swings upwardly into the hopper. The flexible channel 24 is anchored at its ends and intermediately is shaken by a reciprocating frame actuated through a link 99 from a cam 105 on the shaft 21. From the channel 24 the substance falls into the measuring apparatus proper which comprises a disc 25 with diametrically opposed recesses forming measuring chambers.
