Title: A method of heating and chemically reacting pulverulent raw materials and an apparatus for performing the same
IPC: B22F3/00
Filed: 1956-11-07
Abstract: 833,513. Moulding pulverulent materials. DEUTSCHE EDELSTAHLWERKE A.G. Nov. 7, 1956 [Nov. 9, 1955], No. 34072/56. Class 87(2). [Also in Groups II and XI] Pulverulent solid material is heated and chemically reacted by passing it through a rapidly expanding and contracting gap between opposed electrodes while they pass a current through the material and subject it to-pressure impulses. Preferably the current is alternating and the expansion and contraction of the gap is produced by electrode vibration at a frequency corresponding to the frequency of the current. The frequency of vibration and the frequency of the current may be synchronised so that the gap expands or contracts when the current is zero. The action of the electrodes may cause sintering of the material, or a powdery product may be obtained. The reactions may be performed in an inert atmosphere, inert gas may be introduced into the gap from outside, or inert gas may be evolved in the gap by admixing with the reaction components liquid or solid hydrocarbons which would be converted into gas or would evolve the gas by chemical action. In the form shown in Fig. 1, the material is fed by a hopper 11 between hemispherical electrodes 1, made of graphite, carbon or metal, which are water-cooled at 6 and directly carried by the cores 3 of electro-dynamic vibrators 2. The vibratory movements 7 may be performed perpendicularly to the median plane 8 of the gap or inclined thereto as at 9. In the form shown in Fig. 2, the electrodes 13 have humps 14, 15 forming upper and lower gaps in which the material is reacted and hammered, respectively. The humps may or may not be electrically insulated at 16 whereby the lower humps may be operated with a lower current or with no current at all. In other modifications, the electrodes are mounted on cranked levers operated by rod linkages or by cams and springs or weights.

Abstract: 839,898. Examining materials with gamma rays. SIMON-CARVES Ltd. Oct. 13, 1958 [Nov. 5, 1957], No. 34438/57. Class 40 (3). Raw materials issuing from grading or separating apparatus in layers not less than 3¢ inches thick are analysed by subjecting them to a collimated beam of gamma rays of energy 0.015 Mev. to 0.1 Mev. (i.e. wavelength 0.12 to 0.8 A.U.), and the variations of the scattered radiation are used for indicating or control purposes. In Fig. 2 a radioactive isotope is located at the bottom of a cavity in a lead block 3, the collimated rays issuing via an acrylic resinous filter to stop beta rays (Fig. 1, not shown). Washed coal from a hopper 17 falls on to a conveyer where it is immersed in water (so that its moisture content will be known) and carried past the gamma-ray beam. The intensity of the scattered rays, representing the ash content, is measured by a Geiger or scintillation counter 8, whose output can be used in the form of electrical impulses to control washing apparatus and thus reduce fluctuations in the ash content. The rays preferably make an angle of 67¢ degrees with the moving material, the Compton scattering effect then predominating over photo-electric absorption. The radioactive source can be Thulium 170, Americium 241 or Samarium 151. The depth of coal on the conveyer is preferably about 4 inches, and, according to the Provisional Specification, is composed of particles in the range “ to <1>/ 16 inch.

Filed: 1953-12-11
Abstract: 737,075. Latches. FORD MOTOR CO., Ltd. Dec. 11, 1953 [Dec. 11, 1952], No. 34600/53. Class 44. A latch mechanism for a vehicle door has a rotatable bolt 16, Fig. 1, connected by an integral shank 17 to a ratchet 18 arranged to rotate on a flange 12 of an L-shaped mounting plate 11. The bolt 16 is adapted to engage a conventional keeper mounted on the jamb face of the adjacent door pillar (not shown) and rotation of the bolt corresponding to opening the door is controlled by the spring pressed pawl 23 engaging the ratchet 18 which is automatically disengaged to allow rotation of the bolt when closing the door. For a front door latch mechanism Figs. 1, 4 and 5, the invention resides in unlatching or locking the bolt by means of the plunger 41 which is slidably carried in a bush 42 rotatably mounted on a flange 43 of the mounting plate 11. Plunger 41 is pushed through bush 42 by push button 49 to deflect lever 22 clockwise by bearing on flange 39 which by means of the pin and slot connection 36, 37, withdraws the pawl from the ratchet and unlatches the bolt. To lock the mechanism the shoulder 63 of control lever 51 prevents clockwise rotation of lever 22. Control lever 51 can be set in position by rotation of the plunger 41 by the associated lock cylinder 48 which rotates the lever 47, Fig. 5. which is integral with the bush 42 and straddles the narrow end 62 of the control lever 51 which is slidably positioned in a lateral slot in flange 39 of lever 22. The latch may also be locked by remote operation of the control lever by arm 54 from the inside of the vehicle and arm 66, Fig. 4, can be similarly operated to engage arm 27 of the pawl 23 to unlatch the bolt unless arm 56 of the control lever when this is in the locked condition bars the movement of arm 26 of pawl 23. In a latch mechanism for a rear door, Figs. 6 and 7, the control lever 71 is operated by the lever 77, arm 81 of which straddles end portion 73, and is set remotely from inside the vehicle. When lever 77 is set to the position which locks the lever 22 an upturned lug 84 on lever 81, by engaging arm 83 of the lever 82, prevents the latter from unlatching the bolt, by operating the pawl 76, when operated remotely from inside the vehicle.
