Title: Dyeing process
Inventor: MILLS WALTER PERCIVAL
IPC: D06P3/79
Filed: 1961-12-01
Abstract: Fibres of stereoregular polypropylene containing a nickel compound are dyed with mono- or dis-azo dyes devoid of -SO3H groups and containing one metallisable system in which the azo groups form no part of the said system.  The nickel compound may be the oxide, sulphate, carbonate or benzoate but is preferably a salt of a long chain, e.g. 8-18C, aliphatic carboxylic acid such as the octoate, stearate or oleate.  The azo dyes may be derived from 4-hydroxybenzthiazole, 4-hydroxyacridine, 4-hydroxy-benzoxazolone, salicylaldoxime, o-hydroxyacetophenone oxine, salicylic acid and its esters, 2-hydroxy- and 2-amino-3-naphthoic acid and from o-dihydroxy compounds but the preferred dyes are derived from 8-hydroxyquinoline and have the formula <FORM:0966489/D1-D2/1> wherein benzene nucleus A may be substituted with chlorine atoms, alkyl and alkoxy radicals of 1-12C, cyclohexyl, nitro, cyano, trifluoromethyl, lower alkylcarbonyl, lower alkylsulphonyl, di(lower alkyl) aminocarbonyl, di(lower alkyl)-aminosulphonyl, carbo(lower alkoxy) and acylamido radicals.  The dyes may be applied as aqueous dispersions containing the sodium salt of a sulphonated naphthalene-formaldehyde condensate at temperatures about 100 DEG C.  Examples are given in which a sequestering agent, the disodium salt of ethylenediaminetetraacetic acid, is applied to polypropylene fibres containing nickel stearate either after the dyeing or both before and during the dyeing or during all three stages.

Title: Improvements in or relating to logical circuits
IPC: H03K19/10
Filed: 1963-10-16
Abstract: 1,007,386. Tunnel diode logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1963 [Oct. 30, 1962], No. 40746/63. Heading H3T. A plurality of tunnel diodes are connected, each in series with an individual resistor, across a pair of lines such that when a pulse is applied to any diode-resistor junction to switch the diode to its high voltage state the voltage at the lines so varies as to switch the remaining diodes also. In Fig. 5 a current source including a tunnel diode 39 (or a resistor) is connected in series with a number of tunnel diodes 43 arranged in parallel circuits. Diode 39 preferably has peak current equal to the total peak current of the others so that if a low voltage (0) signal is present at all the input terminals 51a-51n the onset of the supply voltage at 47 and 49 causes diode 39 to switch to the high voltage state and all the diodes 43 to remain in the low state. Accordingly a low voltage (0) output is available at point 53 and a high voltage (1) at 67. If however, a positive (1) signal is applied to any of the input terminals 51 the corresponding diode 43 will on the onset of the supply voltage switch to the high voltage state. This will cause a larger current to flow in the other diodes 43 so that they all switch to the high voltage state leaving diode 39 in the low state. Accordingly a high voltage output (1) is provided at 53 and the low voltage (0) at 67. The circuit therefor provides OR and NOR outputs. By rearranging the circuit, AND or NAND logic operation may be performed (Fig. 6). Resetting of the circuit is effected either by the source 47, 49 or by pulses produced by the circuit when it switches being reflected back from the far end of lines 63 and 65.

Abstract: 897,380. Refrigerating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 8, 1960 [Dec. 28, 1959], No. 42267/60. Class 29 Compressed gas is cooled by being supplied to an expansible chamber which is held in compressed condition by a second quantity of compressed gas, and then varying the pressure of the second quantity to allow expansion of the chamber and cooling of the gas therein. As shown in Fig. 1, a compressor C maintains a low pressure in reservoir L and a high pressure in reservoir H. These reservoirs are connected through valves V1 . . . 4 to the top and bottom of a cylinder 8 divided into lower and upper chambers 7, 10 by a piston 9. In operation, piston 9 being at the bottom and valve V3 being open to hold it there, valve V1 is opened to allow high pressure gas to flow to space 7 through regenerative cooler 6 to fill the supply passages. Valve V3 is now closed and valve V4 opened slightly so that space 10 is connected through a restriction to the low pressure reservoir and the piston rises until space 7 is half or more of its maximum volume. Valve V1 is then closed and the gas in space 7 continues to expand until the piston reaches the top of its stroke. Valves V2 and V4 are then fully opened to connect spaces 7, 10 to low pressure reservoir L. Next valve V4 is closed and valve V3 slightly opened so that high pressure gas forces the piston down to displace the cold gas from space 7 through regenerator 6 to receiver L. Finally the cycle is completed by closing valve V2 and opening valve V3 fully so that the high pressure holds the piston lowered. The refrigerant may be helium. As shown in Fig. 9, cylinder 8a includes high and low temperature parts 8b, 8c each having a piston 9b or 9c working in unison. The two sources of gas are separate in systems I and II and spaces 7b, 7c are supplied through regenerators 6a, 6b. The working fluid in system II may be nitrogen. Cold is abstracted from the system by heat exchangers such as 19a, 19b in the pipes between the regenerators and the cold spaces of the cylinder. The apparatus of Fig. 9 may have more than two stages.

Abstract: 1,184,934. Automatic gain control. TELEPHONE MFG. CO. Ltd. 6 Sept., 1968 [18 Sept., 1967], No. 42347/67. Heading H4R. [Also in Division G3] An electrical variable loss network comprises a bridge circuit ABDE with the resistance element of an indirectly heated thermistor TH1 in one arm thereof and its heater connected to the output of one transistor VT2 of a long tailed pair so that the heater current is varied by a control signal applied to the other transistor VT1 of the pair and where the resistance element forms part of the potential divider circuit which provides the base bias for said one transistor VT2. The bias is provided by resistor R9, inductor L1 and the resistance of thermistor TH1 and thus provides temperature stabilization since any change in ambient temperature will affect the resistance of TH1 thereby altering the bias on VT2 to change the current in the heater of TH1. The control signal voltage applied to VT1 is derived from the A.C. signal output and is proportional to it over the working range of 9 dB. Outside this range the control signal voltage remains constant. The variation in resistance in arm DE, to give a 9 dB change, is small so the input impedance of the circuit remains substantially constant. In modifications an amplifier may be included in the feedback loop supplying the heater of TH1 or a directly heated thermistor, connected across the heater of TH1 may be used to provide the main correction.

Abstract: 1501943 Curing articles GATES RUBBER CO 16 Oct 1975 [17 Oct 1974] 42453/75 Heading B5A In a process for curing a vulcanizable or crosslinkable material against mould by the use of a heated fluid acting directly on the material or through an elastic bladder, the curing is effected by a first hot pressurized fluid for a time sufficient to partially soften the article, and then by gas of a lower heat capacity and at a higher pressure. It is maintained that this sequence gives an article of more uniform cure. A preferred fluid is equilibrium steam and preferred gases are nitrogen, air, flue gas, or oxygen. An added advantage, when steam is used as the fluid, is that the gas causes condensation of some of the steam, this giving up latent heat to help maintain working temperatures. The Specification discloses the manufacture of V-belts, tyres and corrugated hoses by this method. In an illustrated example, V-belt blanks are located between a stack of mould elements 52 held secure by end caps 24, 26, and a tubular elastic membrane 40 similarly held. Working fluid and gas is introduced between the membrane and a backing cylinder 42 through valved inlet pipes 19 and 21. The whole assembly is located in a steam kettle 11. In a second embodiment, the membrane may act outwardly to press belt blanks against an embracing stack of mould elements. In a third embodiment, a sleeve from which belt may be cut is radially inwardly or outwardly pressed against a former by an elastic membrane.
