Title: A process for extracting molybdenum
IPC: C01G39/04
Filed: 1964-09-17
Abstract: Pure molybdenum trioxide is produced from materials containing free or combined molybdenum trioxide state by contacting with HCl gas at 150-500 DEG  C., forming molybdic chlorohydrin, MoO(OH)2Cl2 and forming an atmosphere in which locally at a temperature between 70 DEG  and 500 DEG  C. the partial pressure of the chlorohydrin exceeds its equilibrium partial pressure at the temperature concerned whereby molybdic chlorohydrin decomposes in that locality to MoO3 and HCl the latter being recycled to the contacting stage.  The chlorohydrin may be condensed on a cooler at room temperature, e.g. water-cooled and decomposed by heating at 70-500 DEG  C. in a current of air or a gas inert to the chlorohydrin or in an atmosphere of HCl gas from the first stage. In one embodiment the gas stream is brought into contact with a solid body having a lower temperature than that of the gaseous current, but at a higher temperature than the condensation temperature of the chlorohydrin, so that the latter decomposes depositing the trioxide. Alternatively, the molybdic chlorohydrin, after condensation, is heated to over 70 DEG  C. in a stationary or moving atmosphere of HCl, whereby some of the chlorohydrin is decomposed to the oxide while the rest sublimes and may be condensed and decomposed.  This procedure may be carried out as often as required. The raw materials which are preferably in a finely-divided form may be as a fluidized bed or surrounded by an auxiliary fluidized bed; fluidization may be ensured by HCl gas itself or mixed with another gas.

[Also in Division H3] In a television channel selector for reception of either VHF or UHF transmissions, the received signals are passed by a common input stage (valve or transistor) to either VHF or UHF receiving circuits by means of a switch incorporated in the holder for the input valve or transistor. As shown in Fig. 4, the valve holder comprises a laminated base portion surrounded by a metal shield 32. The laminations include, as one layer, a central fixed disc 29 surrounded by a rotatable annular ring 28 having an extension 28, Fig. 6. Situated in recesses between the ring 28 and disc 29 are two movable contacts 22. These make contact with a corresponding pair of valve pins when the valve is inserted in the holder, these pins then serving as pivots for their respective movable contacts. On moving extension 28<SP>1</SP> from the position illustrated to the alternative position as indicated by the arrow, the contacts 22 rotate about their respective valve pins and thus transfer contact from contacts 23 to contacts 24. Fig. 9 shows a construction of transistor holder in which movement of extension 43<SP>1</SP> transfers connection from contact 51 to contact 52. In this arrangement, the movable contact 48 pivots about a hollow metal tube within which the appropriate wire connector of the transistor passes to be soldered thereto at its lower end.

Abstract: 926,053. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 3, 1961 [Nov. 15, 1960], No. 39141/60. Class 39 (4). [Also in Group XXV] An elongate fuel element has end coupling members for connection with other similar fuel elements, the coupling members allowing the fuel elements to be charged into a nuclear reactor as an assembly of connected elements and discharged from the reactor individually. In one embodiment (Fig. 1), a fuel element 1 has a cone 7 screw-fitted to its lower end plug 5, which cone 7 rests in a conical cup 15 screw-fitted to the upper end plug 13 of a second fuel element 9. A bayonet-pin 17 located in a transverse bore 16 in the conical cup 15 rests in the seats 19 of a bayonet-type socket 8 screwed into the cone 7 as the fuel elements 1, 9, along with others similarly connected, are lowered into the reactor. When, however, the lowermost fuel element engages the support grid, helical surfaces 18 on the socket 8 ride over the pin 17 so rotating the fuel element 1 until the position shown in Fig. 1 is reached when the fuel element 1 (and similarly the other fuel elements) can be discharged individually by withdrawal from the top of the reactor. In a modification (not shown), the bayonet-type socket is free to rotate independently of the fuel element of which it forms part. In a second embodiment (Fig. 4), a fuel element 45 has a cone 50 screwfitted to its lower end plug 49, into which cone is screwed an axially-projecting tapered rod 51 having a ball end 52. The lower adjacent fuel element 53 has screw-fitted to its upper end plug 57 a chuck body 59 housing three spring-loaded chuck jaws 60 which receive and grip the ball end 52 as the fuel element assembly is lowered into the reactor core, the assembly being in tension as indicated by the arrow 72. Upon completion of the charging operation, the assembly is in compression, however, and the chuck jaws 60 are forced downwardly below the step 65 in the chuck body 59 and expand outwardly on to the wall 66 so as to render possible the discharging of the fuel elements individually.

Abstract: 1,213,569. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 19 Aug., 1968 [15 Sept., 1967], No. 39593/68. Heading H4P. In a data transmission system the transmitter includes means for determining the ratio of the number of data bit changes : the number of data characters in a stream of data to be transmitted, and for inserting a number of synchronizing bits in the data word stream if the ratio becomes so low that the receiver might lose synchronism. In the embodiment described the ratio must not fall below 1 : 16 over 96 characters. The data bits pass to a unit which delivers a pulse at each bit transition. The transitions are counted in a reversible counter of capacity 6. A second reversible counter, of capacity 16 Î 6 = 96, is stepped forward at character rate by clock pulses, but when neither it nor the transition counter is at zero it is stepped back by 16 in the duration of each character. Under these same conditions the transition counter is stepped back once per character. If the character counter ever becomes full when the transition counter is empty, i.e. if the ratio falls below 1:16 over any period of 96 characters, 6 sync. bits are inserted in the data character stream to be transmitted in order to maintain the ratio of the number of bit changes transmitted : the number of data characters transmitted equal to. 1 : 16.

Abstract: 1479586 Waveguides EMI-VARIAN Ltd 16 Aug 1974 [22 Aug 1973] 39720/73 Heading H1W In a radar system including a transmitter and a receiver connected to a common aerial, the receiver is connected via a section of rectangular waveguide 1, Fig. 1(b), dimensioned such that the operating frequency is just below the cutoff frequency and only an evanescent wave is propagated in the waveguide. A varactor diode 2 is mounted across the waveguide section 1 and means provided for applying a variable voltage across the diode to vary its capacitance. In the absence of the diode the section can only support evanescent modes, at frequencies beyond cut-off, which decay exponentially with distance from the input part of the section. However, since section 1 presents an inductive impedance to frequencies beyond the cut-off frequency, the addition of a capacitance within the section provides a resonant circuit allowing power to be transmitted at or near the resonant frequency of this circuit. By changing the bias voltage on the diode 2 it may be caused to assume its block or pass condition and thus protect the receiver when the transmitter is operating but allow received signals to pass to the receiver. The bias voltage may be derived externally or by rectification of a portion of the radiation incident on the diode. More than one varactor diode may be placed in the waveguide section and may be replaced by other suitable solid state devices. In a modification, Fig. 2 (not shown) the varactor is mounted in a coaxial side arm which communicates with the waveguide section. In a further arrangement, Fig. 3 (not shown) the varactor is connected in series with an inductive stub across the waveguide section to protect the varactor in the blocking condition. This series inductance reduces the effective capacitance change but this is stated to be an advantage in that only a small change is required.
