Title: Moulds for precision casting of metals
Inventor: EMBLEM HAROLD GARTON
IPC: B22C23/00
Filed: 1956-07-25
Abstract: A shell mould for precision casting of metals is produced by applying to an expendable pattern a finely divided refractory material suspended in an alkaline sodium silicate and/or potassium silicate solution, dusting the coating so formed while still wet with a coarse refractory material, applying an acid hydrolysed ethyl silicate solution containing no refractory material, again dusting with a coarse refractory material, and repeating these operations at least once.  The expendable pattern may be of wax, a tin/bismuth alloy, polystyrene or cellulose acetate, and may contain a refractory insert which later forms part of the mould. By repeating the operations 3 to 5 times the mould will be thick enough not to need any external support.  Alternatively the operations may be repeated once or twice and the mould invested in a slurry of refractory material including a bonding liquid.  The mould may be fired prior to casting to at least 900 DEG C. and preferably 1100 DEG C.  If the silica content of the acid hydrolysed ethyl silicate solution is greater than 20% by weight, strong shell moulds can be built up rapidly by consecutive dips in the alkaline slurry and acid solutions without the need for drying between dips, due to rapid gelling.  The alkaline solution includes film-forming, wetting and defoaming agents, and acid may be added to reduce but not neutralize the alkalinity of the solution.  A suitable composition contains sodium silicate, glycerine, hydrochloric acid, ammonium alginate, octyl alcohol, powdered sulphonated lauryl alcohol, flint powder and water. Another suitable composition comprises potassium silicate, sodium dioctyl sulphosuccinate, "Lissapol" (Registered Trade Mark), soap solution, primary alcohol and powdered silica flint.  Amongst suitable ethyl silicates mentioned are tetra ethoxy silane, and those described in Specifications 290,717 [Class 22], 674,137 and 768,232 [Group XXII]. A suitable refractory for dusting purposes is a fireclay grog containing at least 40% alumina.  Prior to applying the first alkaline solution, the pattern may be given an initial coating containing ethyl or sodium silicate and a refractory.  In addition to flint powder this initial coating may contain (1) soap solution, sodium silicate and hydrochloric acid; (2) ethyl silicate containing 2% piperidine, and methylated spirits; (3) ethyl silicate, methylated spirits and water; and may be applied by spraying.  Alternatively the initial coating may be applied by dipping and may comprise, in addition to flint powder, (1) gelatine, glycerine, sodium silicate, hydrochloric acid, octyl alcohol, sulphonated lauryl alcohol, and water; (2) ethyl silicate, methylated spirits, hydrochloric acid and water; (3) ethyl silicate containing 2% piperidine, and methylated spirits; (4) ethyl silicate, gum Arabic, benzene, octyl alcohol and p "Teepol" (Registered Trade Mark).  Specifications 650,466 [Group XXII], 650,532, 712,276 [Group XXII] and 753,228 also are referred to.

Abstract: 1293097 Transistor switching circuits WESTINGHOUSE ELECTRIC CORP 19 April 1971 [24 Feb 1970] 23210/71 Heading H3T [Also in Division H2] A control signal for a gate, e.g. analogue switch #1, is produced by feeding a repetitive signal 7 and a function signal 8 to a comparator 3 to produce a width modulated pulse train which applied to the control electrode of the gate. The arrangement gives a slow turn-on or turn-off depending on whether the function signal 8 is a rising or falling ramp. If the comparator output is fed directly to control analogue switch #1, and via a NOT circuit 10 to control analogue switch #2, a slow fade-over from one circuit to another may be obtained. The system may be used in a lift control system in which three different signals are required to control the movement of the lift between floors. Initially unit 27 produces a " 1 " on line LAND and analogue switch #1 is closed. In this condition the motor is controlled by a signal from time ramp generator 28. During the next phase of operation it is required to charge to control from generator 26, and ramp 8 is initiated to open analogue switch #1 and close analogue switch #2, the summed outputs from the two gates changing gradually. During this phase the output from unit 27 changes to a " 1 " on line LAND to enable AND gate 32 and inhibit AND gate 31. In this condition analogue switch #2 is held open by the output from comparator 3<SP>1</SP>. To change to the next phase, generator 8<SP>1</SP> initiates a ramp which opens analogue switch #2 and closes analogue switch #3 to utilize the control signal from a sensor 29.

Title: Improvements in or relating to freeze-drying processes
Inventor: MUGGLETON PETER WILLIAM
IPC: C12N1/04
Filed: 1954-08-10
Abstract: The moisture content of enzyme preparations to be freeze-dried is controlled by addition of aqueous dextran solution prior to freeze-drying.  The dextran should have a molecular weight within the range from 10,000 to 100,000, and should be salt-free. Preferably from 1 to 10 per cent w/v. of the material to be dried is used.  A compatible wetting agent (preferably acid-free such as the non-ionic polyoxyethylene ethers) may also be added.  In order to prevent over drying, glucose or other inert substance which strongly retains water may also be added to the dextran solution. In an Example (4), a crude culture filtrate containing deoxyribonuclease is mixed with sufficient dextran powder to give a 5 per cent w/v. of dextran in solution, and the so-formed solution is freeze-dried.ALSO:The moisture content of sensitive materials to be freeze-dried such as vaccines, hormones, organ extracts and viruses is controlled by addition of aqueous dextran solution prior to freeze-drying.  The dextran should have a molecular weight within the range from 10,000 to 100,000, and should be salt-free. Preferably from 1 to 10 per cent w/v of the material to be dried is used.  A compatible wetting agent (preferably acid-free such as the non-ionic polyoxyethylene ethers) may also be added.  In order to prevent over drying, glucose or other inert substance which strongly retains water may also be added to the dextran solution. In an example viable B.C.G. organisms (Bacillus of Calmette and Guerin) are collected from a culture medium and suspended in 6 per cent w/v dextran in 5 per cent glucose containing 1/4000 parts of a polyoxyethylene ether.  The suspension is filled into ampoules and freeze dried.

Title: Radio receiving apparatus
IPC: H04B7/08
Filed: 1929-07-29
Abstract: 316,517. Kolster - - Brandes, Ltd., (Assignees of Taylor, A. H., and Young, L. C.). July 28, 1928, [Convention date]. Thermionic heterodyne receivers; fading, preventing.-In order to compensate automaticaly for fading effects, short-wave signals are received on two or more aerials separated by a substantial fraction of the working wave-length and are passed through separate supersonic circuits associated with local sources of different frequency, the resulting signals being fed through separate intermediate-frequency stages, second detectors and low-frequency amplifiers to a common output. Fig. 3 illustrates the arrangement as applied tc C.W. reception. Signals received on aerial 27 are heterodyned by a source 11, and the resulting intermediate frequency is amplified by a screened-grid valve 13 and by a subsequent amplifier 14. After rectification at 15 and further amplification at 16, the resulting note frequency is fed to the primary winding 7 of the telephone receiver 5. The aerial 29 is associated with a similar chain of circuits, except that the frequency of the heterodyne source 17 differs from the first source 11 bv from 10 to 50 kilocycles. Preferably the intermediate frequency transferred to amplifier 13 is approximately 100 kilocycles, whilst that fed to the amplifier 19 is 120 kilocycles. The oscillation frequency of the second detectors 15 and 21 is so adjusted that, in the case of C.W., the resultant note frequencies flowing in the windings 7 and 8 are 1200 and 800 cycles respectively. These give rise to an harmonious chord in the receiver. Any fading effect alternates between the upper and lower notes, thus maintaining an effective overall signal strength.
