Title: Improved catalytic materials
IPC: B01J37/00
Filed: 1945-12-28
Abstract: A catalyst is bonded with a refractory support by mixing the catalyst, or a material which on heating will form the catalyst, with a refractory material and a hardenable organic silicon compound, and allowing the mass to set.  By further heating the mass may be hardened and the binder converted to silica.  The silicon compound may be a partially hydrolysed silicon ester, for example as described in Specification 575,752, [Group IV], or a hydrolysable alkyl or aryl substituted silane.  Examples of suitable catalysts are vanadium pentoxide and finely divided platinum or nickel.  A solvent for example industrial methylated spirits, or a dispersing medium may also be present.  Before setting the mass may be pelleted or moulded into tubes or crucibles.  In examples, catalysts are prepared from powdered sillimanite and vanadium oxide or ammonium chloroplatinate, and are used for the oxidation of sulphur dioxide to sulphur trioxide, naphthalene to phthalic anhydride, and ethyl alcohol to acetaldehyde and acetic acid.  According to the Provisional Specification a small quantity of piperidine is included in the mixture.ALSO:Ethyl alcohol is oxidized to acetaldehyde at 100-150 DEG C., to a mixture of acetaldehyde and acetic acid at 200 DEG  C., and naphthalene is oxidized to phthalic anhydride at 400 DEG  C., using a catalyst prepared by bonding vanadium oxide with sillimanite by means of a hardenable organic silicon compound, for example, a partially hydrolysed silicon ester (see Group III).

Title: Improvements in apparatus for the modulation and keying of radio transmitters
IPC: H03C1/16
Filed: 1949-12-15
Abstract: 658,404. Valve modulating circuits; keying carrier frequencies. MARTIN, C. Dec. 15, 1949, No. 32243. Convention date, Dec. 15, 1948. [Class 40 (v)] In modulating-circuits of the kind in which a modulating-valve L3 is connected in the grid circuit of a carrier amplifier L1, distortion and interruption on negative modulation peaks are prevented by providing a second valve L2 in shunt to the modulator valve L3. The second valve L2 may be employed for telegraphic keying, and a monitoring arrangement may be provided for rendering the keyed signals audible. Both valves L2, L3 have their anodes connected to the earthed positive pole of a D.C. source 12, the negative pole of which is connected to the cathodes through a high resistance 5 and low resistances 3, 4. The grids of the valves L2, L3 are biassed by tappings on the resistances 3, 4, and both cathodes are connected to the grid of the carrier amplifier L1 through a H.F. choke 2. As the resistance of the valve L3 is varied by the modulation source 9 coupled to its grid circuit, the current through the resistors 3, 4, 5, and the voltage applied to the carrier grid, are both varied, to produce a modulated carrier wave in the output circuit of the valve L1. At negative peaks of modulation, the voltage drop in the resistor 4 is reduced and the valve L2 consequently passes more current, thus preventing the grid of the carrier valve L1 from assuming too high a negative voltage. For telegraphy, the microphone 9 is disconnected, and the switch 11 for earthing the anode of the valve L2 is opened. The valve L2 is rendered conductive and non-conductive by opening and closing a key 10. Alternatively the key may open and close the anode-earth connection of the valve L3. The keyed telegraph signals are rendered audible in monitoring phones 21 by providing a back-coupled audio oscillator valve L4 which is rendered operative whenever the key 10 is closed.

Title: Improvements in or relating to constant electric current power supplies
Inventor: KING KENNETH GORDON
IPC: H04B3/44
Filed: 1957-10-16
Abstract: 902,957. Automatic current control systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Oct. 16, 1958 [Oct. 16, 1957], No. 32327/57. Class 38 (4). Power is supplied to a submarine cable from two or more constant current rectifier sets connected in series, one set (the leader) being arranged to supply most of the necessary voltage, the remainder being supplied by the other sets, which are then available to take over the whole of the supply if the leader fails. The rectifier sets may be controlled by either a one or a two stage magnetic amplifier controller, or by an electro-mechanical controller. The controller itself may respond to either the output of a magnetic current discriminator, or a reference circuit embodying non-linear resistors, reference batteries or contact-making ammeters. As shown, each rectifier set M1 is controlled by a magnetic discriminator D1 which carries the cable current. The discriminator is biased by an auxiliary winding 11 in accordance with the difference between a reference voltage 15 and a voltage proportional to the output voltage of the rectifier set so as to progressively raise the normally constant output current when the output voltage is low. The voltage proportional to output voltage is obtained from a winding 31 on the controlled supply transformer and an auxiliary rectifier AM1. A diode AM4 ensures that the bias winding 11 is only effective to raise the output current when the voltage is below the reference voltage. With two such sets sharing the load, the current discriminator of one is adjusted to cause a higher current than the other, and this set supplies most of the power; the other set operates at the point where its low output voltage biases its current discriminator to provide the required larger output. According to the Provisional Specification, the biasing windings may be connected in a series loop, Fig. 3 (not shown). The Provisional Specification also discloses the voltage limiting system described in Specification 902,958 and the switching system described in Specification 902,959.

Abstract: 758,807. Winding yarns. CELANESE CORPORATION OF AMERICA. Nov. 9, 1954 [Nov. 10, 1953], No. 32391/54. Class 120 (2). A winding machine comprises a plurality of mountings for carrying rotatable package supports, said mountings being movable consecutively with, but otherwise independently of, one another from a common operative position where a yarn package support is engaged by driving means to wind yarn on said support to an inoperative position where said support is disengaged from said driving means. As shown, the machine comprises two pairs of articulated arms 29, 28 ; 29a, 28a, each pair being pivoted together at 31, 31a and rotatable about a shaft 32, each pair also being connected by a lost-motion link 44, 47; 44a, 47a. A tube 13 on the expansible mandrel 17 on an arbour 18, carried by the arm 28, is brought into contact with a driven roll 19 to effect winding of the yarn 11 thereon, the yarn being traversed by a guide 22. In the winding position the arm 29, which comprises two spaced bars 36, is supported by a dog 39 attached to a shaft 66 slidable in a sleeve by the operation of a piston 71 in a pneumatic cylinder 72, operated by an electrical timing apparatus 74 (not shown), after a given winding time has elapsed. The removal of the dog 39 allows the arms 29, 28 to move under gravity about the shaft 32, a latch 53 meanwhile engaging a notch 56 in the link 44; the empty tube 13a on the arms 29a, 28a (previously supported by a pin 58 on the arm 29 being brought to a position for winding. As the arms 29, 28 swing to doffing position, a spring-urged pawl 76 carried thereby engages a cut-out 77 in the shaft 32 to hold the arms in that position. Just before doffing position is reached, gravity removes the full package from the restraint of the latch 53 and an adjustable cam-plate 107 on the arm 29 operates an adjustable microswitch 102 which through solenoids 110, actuates a four-way air valve 101 (not shown), to move a piston in a cylinder 94 to rock a shaft 92 and bring a knife 87 into position for severing the yarn extending to the package in doffing position. Air from a perforated pipe 126 blows about the inner surface of the curved plate 89 carrying the knife 87 to ensure that the severed end is taken up by the new tube 13a. After doffing, the operator swings the arm 29, 28 clockwise about the shaft 32 to take up the position formerly occupied by the arm 29a, 28a. The arms 29, 28 ; 29a, 28a are each furnished with compression springs and washers on pins 48, 48a to give damping to the linkage. Specification 746,693 is referred to.
