Abstract: 759,593. Coating and lining moulds; casting. BRENNAN, J. B. Nov. 18, 1952, No. 29120/52. Class 83 (1). [Also in Group V] A liner for a surface on or against which molten material is to be cast is made by applying, e.g. by dip or spray 11, Fig. 4, a liquid suspension 7 of heat-resisting fibres, e.g. asbestos or glass fibres, to one face of a porous backing 8, and subjecting the opposite face of the backing to sub-atmospheric pressure to withdraw the moisture and compact the layer against the backing. The suspension may consist of plaster of Paris and water in addition to the fibres, and the liner may be coated with a filler, e.g. carbon, graphite, plaster of Paris or zirconium oxide. The liner may be used in a mould of porous material, e.g. carbon or tungsten carbide, or may be made on the mould. In one embodiment for continuous casting, interconnected mould-halves 21, 23, Fig. 6, form two endless chains, corresponding halves being joined together for part of their travel, to first receive the liquid suspension from pipe 25. At the next stage, the mould enters a vacuumchamber 28 and may be rotated, and a third heating stage may be provided. Molten casting-material from pipe 26 is supplied to the mould at the fourth stage and finally the casting and liner are stripped. In an embodiment for continuously casting strip or sheet metal, a rotating drum 33, Fig. 7, lined with a preformed liner 35 receives molten metal 31 from an electrically-heated crucible 30. The strip is cooled by device 41 and passes with the liner on to reel 37. Alternatively, the liner may be formed on the drum by spraying or passing the drum through a suspension and evacuating the interior of the drum.

Patent GB-821126-A (GB)
Title: Catalyst preparation
IPC: B01J37/00
Filed: 1957-09-18
Abstract: In the preparation of catalyst pellets, small catalyst particles in the form of powders and finely-divided solids are treated with a solution of colloidal silica of particle size between 10-100  , dried and then pressed together to form the catalyst pellets.  The process is particularly applicable to catalyst particles of the kind unstable to extreme heat treatments.  In an example given 50% (wt.) alumina/50% (wt.) silica alumina pellets are prepared by adding 0.25-1.5 ml. of a solution of colloidal silica containing between 1 to 5% (weight) silica, to every gram of catalyst particles used to give catalyst pellets containing at least 1% and preferably 1 to 7% silica.  The colloidal silica solution should not contain ionic impurities and it can be prepared by (i) adding excess dilute hydrochloric acid to a sodium silicate solution removing the sodium and chloride ions by dialysis through a semi-permeable membrane, or (ii) preferably by diluting commercial water glass with demineralized water and passing the resulting solution over a cation-exchange resin to remove the sodium ions.  Treated catalyst particles are dried to less than 10% (by weight) moisture content and, if necessary, admixed with other components, before pelleting into the final form.  The catalyst pellets can contain silica, magnesia, thoria, alumina, boria, molybdena, chromia or their mixtures as catalysts or carriers with or without tungsten, iron, cobalt, nickel, platinum, palladium combined with phosphates, sulphates and sulphides.

Filed: 1969-06-11
Abstract: 1,212,148. Automatic temperature control systems. HONEYWELL Inc. June 11, 1969 [June 11, 1968], No.29588/69. Heading G3R. An automatic control system for say temperature or pressure has a sensing element controlling a bi-stable switch which adopts one or other of its two stable states in dependence on whether a condition lies on one side or the other of a datum, the switch being energized intermittently through a voltage breakdown device from a relaxation circuit supplied from an A.C. voltage source. A NTC thermistor 66 sensing temperature in a space forms part of a bridge network 62, 63, 67, 68 &c controlling alternative conduction of a pair of differentially arranged transistors 46, 47 which permit conduction of a corresponding one of thyristors 61, 60 connected in series with bi-stable relay coils 33, 34 each shunted by a diode 65, 64. The arrangement is fed intermittently with current by the breakdown of a 4-layer diode 43 forming part of a relaxation oscillator including elements 25-27, which may have a periodic time of 6-8 secs, the power being derived from a transformer winding 14. The arrangement may supply a heating load only hence with a manually operated switch 81 closed, below a determined temperature, relay coil 33 is energized periodically moving a contact 39 on to a fixed contact 38 where it remains temporarily energizing a heating load relay 18, which may control the operation of a furnace. When the temperature rises above a determined value the next pulse from the ocillator energizes coil 34 moving contact 39 on to fixed contact 37 thus breaking the heat control circuit. Alternatively or additionally a cooling control relay 23 may be proved energizable, through a manual switch 80, on the opposite side of a datum to that energizing heating relay 18. A fan 21 energized directly or through a relay is connectible across cooling relay 23 via a manually operated switch 82. A pair of capacitors 70, 71 shunt transient voltages from the gates of the thyristors and the temperature datum is set by a variable resistor 67. Variations in mains voltage only have the effect of charging capacitor 26 at a correspondingly different rate. In an alternative arrangement, one of fixed contacts 37, 38 may be omitted and the windings 33, 34 are connected to the thyristors through a reversing switch. It is envisaged in the Specification that the bridge network may include more than one condition responsive element, also the thermistor 66 may be a resistor variable by a mechanism as an alternative to an inherent physical property. The diode 43 may be replaced by, for example , a gas tube.

Abstract: 1476814 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 15 July 1975 [18 July 1974] 29603/75 Heading H4K A conference arrangement for use in a TDM system employing delta modulation includes for each conferee a store for storing the latest three delta modulation bits for the respective conferee in association with further means for giving an indication each time the latest three bits are identical, there being provided circuitry responsive to said indications from all the conferee individual circuits to determine therefrom a conferee to be nominated as speaker. Such a conference bridge 1 for conferencing up to 10 subscribers is associated with a time switch 2 having a speech bit memory 7 and a connection memory 8, the designations A-D referring to subscribers and the designations C1-C4 referring to the inputs and outputs of the conference bridge. The time switch is used in known manner to provide a two-way connection between each conferee and the conference bridge. In each frame and for each conferee respective detectors 10 determine whether the latest three bits of the respective conferee are identical, i.e. 111 or 000, and a respective counter 11 is stepped each time the identity exists. Circuitry 12 periodically, e.g. every 8 ms., compares the counter outputs and provides a new speaker nomination on the basis that that conferee whose count is the highest is nominated as speaker. Preferably the largest count should exceed a predetermined threshold count. The counters 11 are then reset and the speech bits of the nominated speaker are supplied via a selection matrix to a one bit data memory 14 for supply via the time switch 2 to all of the conferees, until a new speaker is nominated. It is suggested that a time shared counting arrangement could replace the individual counters 11.
