Title: Improvements in or relating to teleprinter systems
IPC: H04L25/04
Filed: 1961-07-07
Abstract: 949,721. Code telegraphy. SIEMENS & HALSKE A.G. July 7, 1961 [July 7, 1960], No. 24662/61. Heading H4P. Apparatus for removing distortion from teleprinter signals on a plurality of leads comprises a clock pulse generator common to all the lines and an individual store for each line, the stores being controlled to deliver stored signals simultaneously and the centre of each pulse in the stored signals delivered being sampled under control of the common clock pulse generator. The clock pulse generator comprises a counter KS1- KS8 fed with clock pulses on lead ZL. Start and stop pulse periods are defined when stages KS1 and KS7, KS8 are " on." Each stage has an associated differentiating circuit which applies a sharp pulse to bi-stable circuit TS2, TS3 at the beginning of each pulse period. When an input line to a writing head SK is seized, contact bk closes and relay C operates to prepare circuits for Ch and Tn over contacts c3, c1 When stage KS7 changes state to begin the stop pulse period, NK operates, followed by Ch which opens contact ch1 to release the bi-stable circuit. Relay Tn operates 10 msec. before the end of the stop pulse and over contact tn1 energizes the advance magnet TS for the magnetic tape Bd. The first pulse read by head AK thus begins half a pulse period in advance of the next sharp pulse applied to the bi-stable circuit which is thereupon switched to the " mark " or " space " state and operates the corresponding relay coil SI or SII according to the position which contact e of relay E assumes under control of the pulses read by head AK. The store may alternatively be a magnetic core shift register.

Title: Improvements in and relating to dyestuffs
IPC: C09B5/52
Filed: 1925-10-03
Abstract: 268,537. Woodcock, W. G., Drescher, H. A. E., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Oct 3, 1925. 1-Amino-2-chloranthraquinone; anthraquinonehydroazines.-A vat dyestuff which gives fast bright blue shades when used for dyeing and printing by the usual methods is obtained by condensation of substantially pure 1-amino-2- chloranthraquinone by the action of a metal or a metal salt in presence of an acid absorber and a diluent such as nitrobenzene or naphthalene. The parent material can be obtained by recrystallizing from sulphuric acid or organic solvents the 1- amino-2-chloranthraquinone obtained according to Specification 264,916. According to examples the crude 1-amino-2-chloranthraquinone is dissolved in 94 per cent sulphuric acid which is then diluted to 70 per cent strength to precipitate the sulphate of the base; the latter is then hydrolysed by boiling with water and the free base heated with copper, sodium acetate or soda ash and nitrobenzene; the resulting dyestuff is freed from copper by vatting or solution in sulphuric acid.

Title: Improvements in or relating to the preparation of arylaliphatic dicarboxylic acid anhydrides
Filed: 1949-09-28
Abstract: Compounds of the formula <FORM:0668574/IV (b)/1> (R1=H or alkyl, R2=alkyl) are obtained by condensing maleic anhydride with C6H5.CHR1 R2 at 80-155 DEG  C. in the presence of 1-10 molar per cent of an organic p  peroxidic catalyst; the number of carbon atoms in (R1+R2) is 1-17.  Nuclear alkylated compounds of the above formula are made similarly from di- and poly-substituted benzenes.  Under preferred conditions the reaction temperature is 80-120 DEG  C. and the catalyst concentration is 1-3 molar per cent. Suitable catalysts are mentioned.  Examples show the reactions with ethylbenzene, isopropylbenzene and 1 : 3 : 5-tri-isopropylbenzene.  Other specified reactants are p-cymene, sec-butylbenzene, n-propylbenzene, o-, m- and p-diethylbenzenes, n- and sec-hexylbenzenes, n-dodecylbenzene and its non-tertiary isomers, and n-octadecylbenzene and its secondary isomers.  When using di- and poly-substituted benzenes, only the largest non-tertiary substituent group reacts.  According to the Specification as open to inspection under Sect. 91, the maleic anhydride may be replaced by maleic or fumaric acid or an ester of one of these with an alcohol ROH, where R is a hydrocarbon radical free from non-benzenoid unsaturation; the corresponding dibasic acids or esters are thus formed.  The aromatic radical may also be a methyl-substituted benzene, and examples are given of the reaction of maleic anhydride with m-xylene and mesitylene.  p-Xylene and durene are also stated to be applicable, but not o-xylene or toluene.  It is also stated that the benzene ring may contain other substituents such as chlorine, nitro, cyano, keto and ether groups, but no example of such compounds are given.  Maleic and fumaric esters that are applicable are those of aliphatic or aromatic alcohols, e.g. methanol, ethanol, the propanols, butanols, hexanols, octanols, dodecanols, octadecanols, cyclohexanol, benzyl alcohol, diphenylcarbinol, phenylethyl alcohol, phenylmethylcarbinol and o-, m- and p-tolycarbinols.  As catalyst, there is additionally mentioned hydroxy cyclohexyl hydroperoxide.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the manufacture and production of interpolymerisation products
IPC: C08F222/14
Filed: 1937-09-17
Abstract: 501,669. Interpolymers of isobutylene and fumaric esters. JOHNSON, U. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 17, 1937, No. 25282. [Class 2 (iii)] Interpolymers are prepared by polymerizing mixtures of fumaric di-esters and isobutylene in an aqueous emulsion in the presence of polymerization catalysts. Fumaric esters specified are fumaric dimethyl, diethyl, di-n-butyl di-isobutyl, dioctyl and di-(ethylene-glycol monomethylether) esters. The polymerization may be carried out in the presence of vinyl compounds such as vinyl esters, vinyl ethers, acrylic acid and their derivatives, styrene, vinyl chloride, vinyl methyl ketone and vinylcarbazole, or maleic acid esters. Soap-like substances containing a lipophilic and a hydrophilic radical are suitable as emulsifying agents, e.g. alkylnaphthalene sulphonic acids, fatty alcohol sulphonates, Turkey red oils, the hydroxyethylation products of fatty alcohols or C-alkyl phenols and the alkali salts of sulphonated mineral oils. Watersoluble organic liquids, e.g. methanol and acetone may also be employed as emulsifying agents. Catalysts specified are hydrogen peroxide, peracetic acid persulphates, percarbonates and perborates. Softening agents or fillers may be incorporated with the emulsion during or after the polymerization. The interpolymers are obtained in the form of a white milk which may be used for priming leather, for coatings, as an adhesive and for impregnating textiles. By adding electrolytes to the emulsions, the interpolymers are flocculated in a fine form, which after separation and drying, may be used as lacquer raw material or for the preparation of cable compositions. In an example, isobutylene and fumaric diethyl ester are emulsified in an aqueous solution of alpha-hydroxyoctadecane sulphonic acid sodium salt with the addition of potassium persulphate and hydrogen peroxide. The interpolymer is precipitated by hydrochloric acid ; after drying a colourless hard mass is obtained which is soluble in methylene chloride, benzene and butyl acetate. A mixture of isobutylene, fumaric diethyl ester and maleic dialkyl ester or styrene may be polymerized under the same conditions.

Title: Improvements in or relating to valves
IPC: F16K17/10
Filed: 1944-12-18
Abstract: 594,140. Fluid-pressure servomotorcontrol systems. PUGH, C. A., BOOTH, D. G., ROUGH, R. W., and PLESSEY CO., Ltd. Dec. 18, 1944, No. 25339., [Class 135] A hydraulic valve for maintaining the pressure in a hydraulic system within preset limits and eliminating the necessity for the supply pump working continuously at full pressure, includes an adjustable pilot valve which enables both the upper and lower limits of the pressure to be varied independently. As shown, an inlet 3 communicates, through a Chamber 2 and check valve 30, with an outlet 4, and a low-pressure byepass 5 is controlled by a main valve 7, adjustably loaded by a spring 8 and adapted to be opened by pressure liquid admitted to a chamber 16 through a passage 32 under the control of the pilot valve. The pilot valve comprises a spring-loaded sleeve 17 slidably mounted in a bore 10, and carrying a needle valve member 21, loaded at one end by an adjustable spring 22 and at the other end by a light spring and being subjected, through a passage 31, to the pressure on the outlet side of the check valve. The relative strengths of the spring 18 loading the sleeve 17 and of the spring 22 are so selected that, under the influence of increasing pressure in the chamber 2, the sleeve moves against its ..spring whilst the needle valve remains seated, the sleeve ultimately engaging an adjustable abutment 20, after which the needle valve opens to admit pressure liquid to the chamber 16, at a pressure determined by the compression of the spring 22 during the movement of the sleeve. Thus, the upper limit of pressure may be varied by axial adjustment of the abutment 20. When the main valve is open, and the pressure in the chamber 2 is reduced, causing the check valve to close, the sleeve 17 is returned, by its spring, to its initial position, but the needle valve is retained open by the pressure of liquid acting through the passage 31, on the plunger 25, until this pressure falls to the lower limit as determined by the adjustment of the spring 22. A restricted passageway 36 in the main valve permits of the escape of pressure liquid from the chamber 16 when the needle valve closes.

Title: Signal selector device
IPC: H04L15/26
Filed: 1952-10-10
Abstract: 765,934. Electric selective signalling systems. INTERNATIONAL MARINE RADIO CO., Ltd. Oct. 10, 1952 [Oct. 31,1951], No. 25434/52. Class 40 (1). Apparatus for initiating a warning signal on receipt of the international distress signal, dashes of four seconds separated by intervals of one second, comprises electronic timing circuits whereby after receipt of four satisfactory dashes a conventional warning device is operated. A pulse oscillator 10 (Fig. 1) operating through frequency dividers 13, 14 produces timing pulses at half-second intervals which can be fed through gates 20, 21 to dash timer 23 and space timer 24. Receipt of a dash 22 from a receiver, not shown, zeroizes frequency divider 13 and timer 23, and opens gate 20 to allow pulses from 13 to pass to timer 23, the seventh pulse, after 3¢ seconds, opening gate 26, and the twelfth pulse, after 6 seconds, closing gate 26. If the dash 22 is between 3¢ and 6 seconds duration the trailing edge is differentiated in a pulse shaper 40, and passes through gate 26 to be recorded on a register 39, and is also fed to reset stages 32, 33 to zeroize frequency divider 14 and timer 24, and open gate 21. Now pulses from frequency divider 14 are fed to timer 24, and on the third pulse, i.e. after 1¢ seconds, the timer is actuated to produce a square pulse 42 which closes gate 21 and opens gate 34. If the dash 22 has not been followed in this time by a further dash, gate 37 is also open, and oscillator 10 feeds through gates 34, 37 to operate reset circuit 36 and zeroize register 39. Consecutive dashes and intervals are measured in this way, and if within the standard tolerances of 3¢ to 6 seconds for the dash and up to 1¢ seconds for the interval are registered on 39, departure from the tolerances causing gates 34, 37 to be simultaneously open, whereupon oscillator 10 operates reset circuit 36 to zeroize register 39. After receiving four dashes the register 39 produces an output pulse 62 which operates a warning device 63. Reference is made to Specification 765,935 in which satisfactory circuits for timers 23, 24 are described. Specification 495,940 also is referred to.
