Title: Production of uranium monocarbide
IPC: C01B31/30
Filed: 1962-05-28
Abstract: <PICT:0970627/C1/1> Uranium monocarbide is made by mixing UF4, Si and C, pelletizing, allowing the mixture to react at 1,500-1,700 DEG  C., continuously removing the SiF4 evolved, and cooling and arc-melting the UC powder to produce a massive UC body.  The C, UF4 and Si in mol. ratio 0.84 : 1 : 1.12-1.24 are pressed into pellets or rods at, e.g. 25 tons p.s.i., and may be loaded on to a graphite boat 30, as shown in Fig. 1, inserted into the graphite reaction tube 12 with insulation 13.  Dried argon may flow through tube 10, entering at 16 and leaving at 22, removing the SiF4 evolved which may be collected in BaCl2 in absorber 27.  The pellets may be heated inductively by coil 11.

Abstract: 294,152. Elias, J. J. M. July 18, 1927, [Convention date]. Cutting sugar cane etc.; disc tool implements with adjustable tool frames; tools; travelling and propelling gear. - Sugarcanes or similar crops are guided between two lateral dividers 1 having inclined upper edges from which upper edges rotary cutters 2 project to cut off stems lifted by and moving upwards along the dividers. Lifting members for the roots are situated between the dividers. The harvesting appliance is adjustably mounted in a frame of girders 14, 15 adapted to be secured to a motor tractor. To bend over the cane and to cut off the tops a curved ladder 16 is secured to the front of the machine, its lower end being pivotally secured to the girders and its upper end to an adjustable frame 17 having a forwardly projecting comb 18 that is maintained horizontal. The frame 17 carries two sets of rotary saws 20 driven from the motor to cut off the tops engaged by the fingers of the comb, such fingers being provided with knife edges 19. According to the Specification as open to inspection under Sect. 91 (3) (a) the lifting members comprise coulters 3, 4, Fig. 4, (Cancelled) provided on their inner sides with inclined detachable guide plates 5, and also a hoeing blade 6 secured to a horizontal bar 7 attached to the coulters.

Abstract: 865,168. Electromagnetic switches. ELECTRO-APPARATE-WERKE J. W. STALIN VEB. June 17, 1959, No. 20779/59. Class 38 (5). [Also in Group XXXV] A magnetic system, particularly for an electromagnetic switch has two relatively movable parts and a magnetic shunt which is moved away from one of the parts, to allow saturation thereof, as the parts approach each other on energization of the system by a coil. The fixed parts include a yoke 2 and a coil 9 which when energized attract an armature 1 against the action of return springs (not shown), the initial flux following a path # 1  in the yoke and a path # 2  in a shunt 3 across the end thereof. After the armature 1 has travelled a short distance, pins 10 thereon engage the ends of slots 8 in rods 6 coupled to the shunt 3 so as to move it away from the yoke 2 allowing saturation of its upper port. This is said to give a linear force/travel characteristic reducing the impact strain between armature and yoke. The shunt 3 operates plungers 5 to actuate the switch contacts (not shown), and contact chatter is limited by a buffer 4 of elastic material such as crepe or soft rubber. In a modified arrangement parts 1, 3 may be fixed and 2 movable.

A flexible windscreen cleaner 'for flat or curved surfaces has a holder 6 comprising a pair of flexible metal strips 15 which engage corresponding grooves 14 located on either side of a wiper element 3, so that the element may only flex in a plane perpendicular to the surface to be wiped, and fastening brackets 18, 19 which retain the wiper element and the strips in assembled relationship. The holder is attached to a pressure distributing bridge as disclosed in Specification 666,473. The grooves 14 in the wiper element are formed in a head portion 40, a wiping portion 7 being flexibly connected thereto by an integral neck portion 41. A plurality of wiping edges are provided on the wiping portion in the manner disclosed in Specification 347,198, so that flexing of the wiping portion causes more than one wiping edge to engage the windscreen if the resistance to movement of the wiper body is large. Indentations formed in the brackets engage corresponding recesses in the strips (not shown) and prevent relative movement between the parts. In a modification the flexible strips are press-fitted into narrow grooves 14, or alternatively the grooves may be V- shaped.

[Also in Group XXIII] A work-holder for brushmaking machines comprises a body rotatably mounted on a fixed shaft and having a number of relatively fixed clamping jaws mounted in spaced positions around its circumfererice, and a number of co-operating movable clamping jaws mounted in a groove in said body, means being provided on the surface of said shaft in operative association with said movable jaws which, upon rotation of said body, automatically open and close said jaws at predetermined positions of rotation. The work-holder comprises supporting brackets 1, Figs. 1 and 11, for fastening to a brushmaking machine. The brackets support between them a shaft 2 and carry members 4 with rods 5 arranged in a triangular pattern in plan view, the rods supporting the brush stocks in stack arrangement, Fig. 11. A cylindrical body 6 is intermittently rotatable about the shaft 2 by a pawl 26 and ratchet wheel 25, Fig. 4, secured to the body 6. A spring- pressed stop-pawl 29 prevents inadvertent movement of the body 6. Steps 7 are cut on the latter to form one jaw on each of the four work-holding faces. A groove 8 formed centrally of the body 6 accommodates a number of spring-pressed fingers 9, Fig. 6, with gripping ends 10 to co-operate with the steps 7 in gripping the work. The inner ends of the fingers bear on the stationary supporting shaft 2 which is flattened at diametrically-opposite points so that the jaws are opened. The indexing movement of the work-holder may be obtained from a Geneva mechanism, and alternative arrangements for operating the gripping fingers are described including fluid-pressure means. An arrangement of work-holders in a brush-making machine, Fig. 11, comprises a top holder, with a stack of brush stocks 32, to present the stocks one at a time to a drilling-head 31, after which they are indexed to the underside position where release is effected and the stocks guided on to an intermediate holder. The latter is provided for reversing the stocks so that at the third work-holder they occupy the same position, with the drilled holes facing outwardly, that they occupied at the first work-holder. The stocks are thus presented to a tufting head 30 and finally discharged.

As shown, drum 4 is rotatably mounted on bearings 11 in vat 1 and comprises a perforated metal sheet supported by portions: 5 on shaft 6. The drum is closed at one end by end plate 104 and the other open end revolves in a groove in ring 10. Feed is introduced into container 8 together with air via lid 25 and frothing reagent added from doser 37. They are drawn into the drum by a screw impeller 26 and the rotation of the drum throws the pulp mixed with air and frothing agent out of the non- immersed part of the drum in the form of a froth. The froth is removed into a channel 28 by revolving skimming blades 27. Treated pulp can be returned to the drum by closing the normal outlet and opening valve 24 in ducts 23 so that pulp in vat 1 is returned to chamber 8 and to the drum. The level of liquid in vat 1 is controlled by overflow sluice 43 which can be raised or lowered by means of screw spindle 42 and control nut 41.
