Patent GB-931133-A (GB)
Title: Data processing system
IPC: G06F9/30
Filed: 1962-05-08
Abstract: 931,133. Electronic computer. RADIO CORPORATION OF AMERICA. May 8, 1962 [May 25, 1961], No. 17722/62. Class 106 (1). A data processing system comprises a plurality of processing stages connected in cascade, means for simultaneously transmitting control signals towards each of said stages and a plurality of circuits each arranged to supply a start signal to an associated processing stage, to which it is connected, in response to the receipt of both of one of said control signals and an output signal indicating that the immediately preceding stage has completed its operation. In the arrangement described, a computer instruction is applied over a lead 10, which may include 28 separate wires for a 28-bit instruction word, to an instruction register 12 whose outputs are decoded in a decoder 16 and supplied to generator 20 which produces the required pulses to the instruction. As described, simultaneous pulses a<SP>1</SP>, b<SP>1</SP>, f<SP>1</SP>, h<SP>1</SP>, Fig. 2, are produced on leads 22, 24, 26, 28 to control the operation of computer stages A-D. Computer stages A, C, and D are synchronous, i.e. require a predetermined time for completion of an operation therein but computer stage B is asynchronous, i.e. requires a variable operation time, a pulse being produced on a lead 38 when an operation therein has been completed. Due to variations the time of operation of gates in the circuitry and to variations in the delay produced by transmission leads of varying length, the control pulses arrive at their distinations at different times, as shown at a, b, f, h, Fig. 2. When signal a arrives at stage A, this stage operates and after a predetermined time produces an output word to the next stage at 44. The pulse a is supplied also to a delay 30 arranged to have a delay time equal to the operation time of stage A so that, simultaneously with the appearance the output word at 44, a delayed signal c is applied to a gate 32 which, being already or shortly afterwards enabled by the control signal b, produces an output at d to start the operation of stage B. Stage B is asynchronous and produces an output e applied to gate 34 when its operation has been completed. The gate 34 controls the operation of the next stage C. The control circuitry for stages C, D, is similar to that for stage A. In a practical example (Figs. 4-12, not shown), stage A is a synchronous switch for supplying two binary coded decimal excess-3 numbers to stage B, which is an asynchronous parallel adder, the output of which is converted to excess-3 form at stage C and applied by stage D, which is a synchronous switch, to one of two alternative accumulator registers.

Abstract: 796,209. Injection-moulding machines. SAUTER, H., and HAHN, W., [trading as HAHN & KOLB]. June 8, 1956 [June 15, 1955], No. 17730/56. Class 87(2). [Also in Group XXII] In a die casting or injection moulding machine, of the type in which a movable mould carrier is movable into its closed position by a small force and the mould is maintained closed by a closing piston executing a relatively small stroke in its cylinder, the cylinder 16 of the closing piston 17 is displaceable in a closing frame 2 of the machine to permit it to be brought into alignment with an intermediate member 18 through which the piston transmits a mould closing force in the line of action of the resultant of the mould bursting forces when the mould carrier 7 is in the closed position, and to be brought out of the path of the intermediate member when the mould carrier is out of the closed position, the intermediate member being adjustably displaceable so as to ensure transmission of the full force of the mould closing piston to the mould in said line of action. The movable mould half 5 is moved to the closed position by a piston 12, and held closed by a piston 17 acting through the intermediate member 18. The cylinder 16 is vertically movable in a guide 15 by means of a piston 22. The guide 15 and the intermediate member 18 are transversely movable by hand wheels 25, 31, so that the axes of the piston 17 and the member 18 may be positioned to coincide with the line of action of the resultant of the mould bursting forces.

Title: Improvements in or relating to electric power regulating equipment
Inventor: PEASE EDWARD
IPC: C23F13/04
Filed: 1958-06-04
Abstract: 868,450. Automatic control systems for cathodic protection arrangements. STANDARD TELEPHONES & CABLES Ltd. May 29, 1959 [June 4, 1958], No. 17823/58. Class 38 (4). In a cathodic protection system for, e.g. a ship's hull in which current is passed between an external anode the hull, the current is controlled in accordance with the output of a zinc reference electrode, together with a current limiter. The hull 3 and anode 4 are supplied by a rectifier 2 from an A.C. source 1 under the control of a self-saturating reactor 9. A zinc reference electrode 5 is mounted adjacent the hull 3 and the output voltage of the cell so formed is compared with a reference voltage derived from a rectifier 15 and an external source 14. The resultant controls the reactor 9 through self-saturating magnetic amplifiers 11, 21. The amplifier 21 also has a winding connected to the A.C. supply 1 through a rectifier 22 so as to compensate for fluctuations in supply voltage. A further selfsaturating magnetic amplifier 10 has its output connected in series with the output of the amplifier 21 and is controlled by the main supply current and an opposing bias. If the supply current exceeds a predetermined level, the impedance of the amplifier 10 becomes higher than that of amplifier 21 and so takes over control to maintain the current at a level higher than that normally required to maintain the hydrogen film. This enables the film to be initially established at a rapid rate.

Title: Control for gas burners
Inventor: CLIFF THOMAS CHARLES
IPC: F23N5/06
Filed: 1967-04-20
Abstract: 1,201,482. Gas burner controls. BRITISH THERMOSTAT CO. Ltd. 17 April, 1968 [20 April, 1967], No. 18277/67. Heading F4T. A gas burner control comprises a gas governor 15 consisting of a thermally responsive device connected to an expansible unit 31 which influences the force of a spring 30 acting to open a valve 18 in a weep line 16 in the supply to a main burner, expansion of said unit 31 closing the valve 18 to effect closure of a valve 20 in the main supply to the burner, and has a flame failure device 4 to supply gas to a pilot burner and activated by a thermocouple 12 such that when the flame at the pilot burner is extinguished the device 4 shuts off the gas supply to both the main and pilot burners. Manual depression of a device 21 urges a valve member 5 of safety device 4 away from its seating 7 against the action of a spring 6 to allow gas to flow to the pilot burner. Flow to the main burner is, however, prevented by a disc 23 on the device 21 abutting the sealing 7. When the pilot has been ignited its flame acts on the thermocouple 12 to energize an electromagnet 13 which then holds the valve member 5 open and thus release of the device 21 allows gas to flow to the main burner via weep lines 16, 19 and a main line containing a diaphragm valve 20. As the temperature of the apparatus heated by the main burner rises the expansible unit 31 forces a lever 24 away from a diaphragm 34, thus relieving the pressure exerted on a block 35, which mounts the valve 18, by the spring 30 mounted on a second lever 28. Gas pressure on the diaphragm 34 is then sufficient to cause partial closing of the valve 18, causing gas to pass through a restricted orifice 37 to a chamber 39 effecting partial closure of the diaphragm valve 20. When a predetermined temperature is reached the lever 24 is held down with a "snap action" by a magnet 44, thus allowing valve 18 to fully close and a sufficient pressure to build up in chamber 39 to close valve 20. Extinction of the pilot flame deenergizes the electromagnet and valve member 5 returns to its closed position.

Patent GB-974478-A (GB)
Title: Unsaturated aldehydes
IPC: C07C45/81
Filed: 1961-05-19
Abstract: An unsaturated aldehyde is recovered from the product of the catalytic oxidation of an aliphatic olefin with oxygen by removing the bulk of water from the vapour from the oxidation step by a single- or multi-stage condensation, separating the unsaturated aldehyde by washing the residual gas with a C6-C20 branched chain hydrocarbon at a temperature between 0 DEG C. and -70 DEG C. and recovering the unsaturated aldehyde from the wash liquor by rectification. The process is particularly suitable for the recovery of aldehydes containing 3-6 carbon atoms. Suitable hydrocarbons for the washing step are, for example, iso-octane, propylene trimer and propylene tetramer. The washing may be carried out in one or more steps. In an example a propylene-propane mixture is oxidised with air in the presence of a catalyst consisting of molybdenum oxide, bismuth oxide and silica, the product is condensed to remove the water, is treated with propylene tetramer at -20 DEG C. and -50 DEG C. and then fractionated to give acrolein. Similar results are obtained if iso-octane, propylene trimer or a C9-C11 Fiseher-Tropsch fraction is used instead of propylene tetramer.

Title: Improvements in and relating to apparatus for the aqueous liquid treatment of textile thread
IPC: D01D10/04
Filed: 1953-07-03
Abstract: <PICT:0734150/IV (a)/1> <PICT:0734150/IV (a)/2> <PICT:0734150/IV (a)/3> In apparatus for the treatment of fibres, e.g. viscose rayon, with a number of different liquids and comprising a pair of inclined rollers over which the thread passes in a substantially helical path, one roller comprises a plurality of separate cylinders mounted on a common shaft and provided with means whereby the cylinders may be brought together during the lacing-up operation to form a single continuous surface and whereby the cylinders may be subsequently spaced apart along the common shaft to permit each cylinder to receive a respective treatment liquid without danger of contamination by liquid applied to the adjacent cylinders.  As shown in Fig. 1, the apparatus comprises an upper roller 5 supported at one end and a lower roller comprising a plurality of separate cylinders 6a . . . 6f mounted upon a hollow shaft 4 supported at both ends.  A bar 10 may be moved axially within the shaft 4 by operation of a handwheel 8. The cylinders 6a . . . 6f are mounted upon separate sleeves 12 upon the shaft 4 and are urged to make contact with one another by means of the springs 11 mounted between the sleeves 12 and stops 16.  Upon rotating the handwheel 8, the rod 10 moves to the left, carrying with it a plurality of studs 13 passing through slots 14 in the shaft 4 and engaging within slots 15 in the sleeves 12. Successive slots 15 along the lower roller increase in length from a left-to-right direction so that the left-hand stud 13 engages its corresponding sleeve 12 first and moves that to the left before the next stud engages the succeeding sleeve 12 and so on. The lacing-up of a thread is carried out from right to left with the cylinders brought together, the thread being assisted manually past the small projections 19 on the cylinders.  The hand-wheel is then rotated to separate the cylinders and the trough 25 is brought to the position shown in Fig. 2.  The projections 19 prevent the thread from slipping into the spaces between the cylinders.  The treatment liquors are supplied from tubes 27 and flexible protecting surfaces 17 are arranged between the cylinders to prevent liquid from getting inside the lower roller.  Fig. 7 illustrates a modification in which thread guides 121 are provided for carrying the thread from one cylinder to the next.  The guides are mounted on a rotatable hollow shaft 119 so that they may be moved from a position in which they do not engage the threads to one where they do.  The shaft 119 is of construction similar to that of the lower roller so that on rotation of the hand-wheel 8 the guides move together with the cylinders 6a . . . 6f. In this arrangement the projections 19 on the cylinders need not be provided.  The edges of the cylinders may be toothed so that in the closed position they interdigitate with one another.

Abstract: 1,222,575. Polyamide acids, polyimides; organosilicon polymers; curing epoxy resins. GENERAL ELECTRIC CO. 18 April, 1968 [15 May, 1967], No. 18461/68. Headings C3B, C3R and C3T. [Also in Division C2] Polyamide acid resins are prepared by reacting a diprimary organic amine with dianhydrides prepared by the method of the invention (see Division C2) and having the formula where Z is oxygen, sulphur or the -NR- radical, Q is a divalent organic residue and R is a monovalent aliphatic hydrocarbon radical or, when both Z's are -NR- radicals, the R's and Q's may together with the nitrogen atoms form a ring structure (see Heading C2C). These resins on heating e.g. at above 200-300‹ C., form the corresponding polyimide resins. Specified amine compounds (1) have the formula NH 2 -R<SP>1</SP>-NH 2 , where R<SP>1</SP> is a divalent organic radical containing at least two carbon atoms and includes ethylene diamine, phenylene diamines, p,p<SP>1</SP>-methylene dianiline, 4,4<SP>1</SP>-diamino diphenylsulphone and bis - (4 - aminophenyl)- diethyl silane ; and (2) are organopolysiloxanes containing at least two amino groups attached to silicon through a carbon atom such as those of formula where R<SP>111</SP> is a monovalent, and R<SP>11</SP> a divalent, organic radical and m is a whole number from 1 to 1000 or more, e.g. 1,3-bis-delta-aminobutyl tetramethyl - disiloxane and organopolysiloxanes of formula at least two of the R<SP>111</SP> groups being substituted with an -NH 2 group and a has a value from 1 to 3 inclusive. The reaction between the dianhydrides and the diamino compounds may take place in a solvent e.g. dimethyl formamide, N-methyl-2- pyrrolidone, cresol and dimethyl sulphoxide at from room temperature to 100‹ C. followed by heating at 150-400‹ C. if cyclization leading to the imide is required. In examples, the trimellitate of Formula I where Z is O and (12) Q is -CH 2 -CH 2 -, (14) Q is -CH 2 C(CH 3 ) 2 - CH 2 - and (16) Q is (CH 2 CH 2 ) 2 O are reacted with p-p<SP>1</SP>-methylene dianiline in N-methyl pyrrolidone to give the corresponding polyamide resins which on heating give the polyimide resins, while the trimellitate of Example (11) in the same solvent is reacted with 1,3- bis-delta-amino-butyl tetramethyldisiloxane together with (19) p-p<SP>1</SP>-methylene dianiline to give the polyamide which on heating gives a polyimide composed of recurring units of formula and of formula or (18) when the dianiline is omitted, recurring units of Formula VIII only. Epoxy resins are cured by reaction with dianhydrides of Formula I (above). Examples are given of their curing in acetone by the dianhydride in which Z is oxygen and Q is (13) -CH 2 -CH 2 -, (15) -CH 2 -C(CH 3 ) 2 -CH 2 - and (17) -(CH 2 -CH 2 ) 2 O.
