Patent GB-354326-A (GB)
Title: Improved method of dyeing acetate silks
IPC: D06P1/62
Filed: 1930-02-03
Abstract: Mineral oil sulphonic acids or salts thereof obtained as by-products in the treatment of mineral oils with fuming sulphuric acid or sulphur trioxide, are used for dispersing dyestuffs and intermediates in dyeing acetate silk or a mixed fabric comprising acetate silk with wool or natural silk.  In conjunction with the usual thickeners, the sulphonic acids or salts thereof may be used in printing acetate silks.  Both the water soluble and the "mahogany" or oil soluble sulphonic acids may be used, and in the preferred process, oil soluble sulphonic acids which have been freed from entrained oil are employed.  This may be effected by treating with alcohol and aqueous sodium carbonate when the oil separates and the oil soluble sulphonic acid forms a soap.  Water and alcohol are removed from the soap by distillation and further oil is extracted by agitation with alcohol. The solubility of the oil soluble sulphonic acids is improved by mixing therewith white oils or paraffin oils, aromatic or hydroaromatic solvents or chlorinated paraffin or aromatic solvents, and mixtures of the water soluble with the oil soluble sulphonic acids may advantageously be employed.  In examples: (1) a dye bath for acetate silks is prepared with Cibacet yellow G N and purified oil soluble sulphonate; (2) Acetate silk is dyed a deep purple in a bath containing Methyl violet base and the sodium salt of a water soluble mineral oil sulphonic acid; (3) material containing natural and acetate silk is introduced into a bath prepared by adding Acid orange Y dissolved in aqueous acetic acid to a dispersion of Cibacet orange 3 G prepared by means of a mixture of paraffin oil and oil soluble sulphonate.  When the dyeing of the acetate silk is completed the dyeing of the natural silk is effected after adding sulphuric acid; (4) Acetate silk is immersed p  in a bath of p-nitraniline prepared with oil-soluble sulphonate and then in an acidified sodium nitrite bath.  After excess liquor has been removed the fabric is immersed in a slightly alkaline solution of b -naphthol. Specifications 19676/12 and 127,159, [both in Class 2 (iii), Dyes &c.], are referred to.  Reference has been directed by the Comptroller to Specification 224,925, [Class 2 (iii), Dyes &c.].

Abstract: 1,211,412. Semi-conductor devices; circuit assemblies. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Jan., 1968 [27 Jan., 1967], No. 3678/68. Headings H1K and H1R. A support for one or more transistors or monolithic integrated circuits comprises an insulating substrate with projections constituted by conductive layers electroplated to a thickness exceeding that of the transistors or circuits which are to be mounted between the projections with their supply conductors electrically connected to them. The supports can be made in multiple from a borosilicate glass or enamelled ceramic plate by first vapour depositing through a metal mask to form a repeating pattern of conductive tracks 35, 36, 37 (Fig. 6) consisting of 1-2Á thick aluminiumchromium with a 200 A‹ overlayer of chromium. Then the entire surface is coated by vapour deposition with copper which is thickened by electroplating either before or after provision of a photo-resist mask exposing only the sites of the projections. The copper on the unmasked areas is then electroplated with a 2-3Á layer of gold. After removing the photo-resist the plate is etched in nitric acid to remove the copper save where it is protected by the gold. After ultrasonically soldering the terminals of transistors 34 to the conductive tracks and coating with resin the plate is sawn up into single units. In another method the conductive tracks are made by depositing goldcoated chromium overall and then patterning by etching with aqua regia through a photoresist mask. If desired, a plurality of transistors and associated circuit elements are attached to each unit of the support with the projections attached to the terminals of the elementary circuits thus formed. The supports are intended for soldering in an inverted position on hybrid circuit boards.

Title: Majority gate storage circuits
IPC: H03K3/037
Filed: 1965-01-28
Abstract: 1,100,121. Shift registers. RADIO CORPORATION OF AMERICA. 28 Jan., 1965 [6 Feb., 1964], No. 3864/65. Heading G4C. [Also in Division H3] A feedback type bi-stable circuit suitable for use in a shift register comprises a threshold logic element to which is applied the information input signal, the feedback signal and a control signal which effectively varies the threshold. Fig. 3 shows a binary storage circuit including a majority logic threshold gate comprising an emitter biased transistor 24 having two input terminals y 1 , y 2  connected to output terminal Y so that the circuit is bi-stable. Switching between states will take place only when a, b and x are all opposite to y 1  and y 2 . When both a and b are " 1 ", signal x will switch the circuit to the " 1 " condition but not to " 0 ". Similarly when a and b are both " 0 " x will switch it to " 0 " but not to " 1 ". When a and b are different the circuit will switch to the state corresponding to x. In Fig. 5 (not shown) control of the response to an input signal x is effected by four inputs. Fig. 8 shows a bistable circuit comprising a threshold gate 88<SP>1</SP> (of the type illustrated in Fig. 6, not shown) having a signal input terminal x 1  which may receive a combination of logic signals and a second terminal x 2  providing the feedback and weighted more heavily because of the smaller input resistor 110. A threshold signal is applied to the emitter and may have five levels. At the two extremes of these levels (i.e. 0V and 2V) the circuit switches to a corresponding one of its two stable states irrespective of the input signal applied at x. At the mid level (i.e. 1À2 V), the state corresponds to the binary level of x. At the upper and lower intermediate levels (i.e. 1À9 V and 49 V) the input x will switch the circuit to a state corresponding to the respective level but not back again. In Fig. 4 (not shown) a plurality of parallelinput shift registers 50, 60 are coupled, the output of each stage of one register, e.g. 50 being coupled to the corresponding stage of the next, e.g. 60, each stage comprising a bi-stable threshold gate as shown in Fig. 3. To transfer the information from one of stages 50 to 60, oppositely going shift pulses P 1 , P 2  are applied, P 1  occurring slightly before P 2 . Accordingly the inputs a and b both firstly become " 1 " so that if the output from the stages 50 is " 1 ", the majority input is also 1 and the bi-stable circuits switch to the " 1 " state providing they are not already there. When P 1  ends P 2  is still present and both a and b inputs are " 0 ". The bistable gates receiving a " 1 " input input are not effected but the bi-stable gates receiving a " 0 " have the majority of their inputs at " 0 " and are switched to the " 0 " stage if they are not already there. The shift pulses to stages 60 are delayed at 74, 60 and are therefore reset subsequently to stage 60. The delay circuits may be omitted if the pulses are derived from a ring counter.

Abstract: 564,136. Wireless signalling. HAZELTINE CORPORATION. March 10, 1943, No. 3912. Convention date, May 8, 1942. [Class 40 (v)] In a two-way signalling system in which an antenna is coupled to the receiving or transmitting apparatus through a channel comprising a pair of vacuum tubes which are selectively energized according to the direction of transmission, means are provided for reducing the transmission of signals in the undesired direction due to undesired reactance in the energized tube, such means including the corresponding undesired reactance of the unenergized tube. As shown in the Figure, the apparatus comprises a tuned antenna circuit 10, 11 coupled to a tuned terminal circuit 25 of a translation channel 16, having a further tuned terminal circuit 26 coupled to a conventional two-way signal communication apparatus 21 including a microphone 23 and loud-speaker 24 and transmit-receive switch 22. The winding 28 of circuit 25 is connected to the control grid 35 of an amplifier 33 and to the anode of an amplifier 34. The anode of 33 is connected to one half 32b of a winding 32 of circuit 26, while the control grid of 34 is connected to the other half 32a. When switch 22 is set to the receive position, a ganged switch 37 is set to energize the cathode of valve 33, and the arrangement is adapted to operate as a super-regenerative receiver. When switch 22 is set to transmit, switch 37 effects energization of valve 34, and the modulated oscillations from 21 are fed through half winding 32a to the grid of 34 for transmission through circuit 25 and antenna 10. During reception, oscillations from the super-regenerative detector may be fed back to the antenna through half winding 32b and the inter-electrode capacity 42 of valve 33. These are, however, balanced by oscillations of equal amplitude and. opposite phase which are fed to the same point from the other half 32a of winding 32 through the inter-electrode capacity 43 of valve 34. - Similarly, during transmission, a tendency for valve 34 to self oscillation due to feed back through interelectrode capacity 43 is checked by a reverse feed back through inter-electrode capacity 42 to the lower end of winding 32. By proper choice of resistance 46, it is arranged that there is no change in the resistance effectively coupled to tuned circuit 30, which is the frequency determining circuit of the oscillator in 21 on switching from transmission to reception.
