Title: Improvements in or relating to telecommunications exchange systems
IPC: H04L12/52
Filed: 1966-07-27
Abstract: 1,107,067. Data transmission systems. SIEMENS A.G. 27 July, 1966 [28 July, 1965], No. 33763/66. Heading H4P. In an exchange system in which each subscriber is connected to a multiple line and transmits or receives each bit on a combination of channels in said line which is unique to the calling or called subscriber, dialling and control signals are transmitted on the same combination of channels but are distinguished from the binary data by modification by a preset signal. To call the exchange a subscriber pulses his combination transmitter at the exchange. This energizes a unique combination of channels and also two additional channels. The latter cause a free connector set to be seized and causes the unique combination to be stored and a monostable unit to be triggered. When now a call-up pulse arrives at the connector set, gating means pulse a combination of channels identical to that stored. This pulse therefore passes to the calling subscriber's combination receiver. A pulse is also passed over the additional channels to that receiver. A further pulse passes over all these channels when the monostable unit resets. In response to the pulses the combination receiver indicates to the calling subscriber that the exchange is ready to receive dialling pulses. The dialling pulses pass on the calling subscriber's unique combination, together with pulses on one of the additional channels, through gating units to a counter which generates a signal on a combination of channels representing the called station. This signal is used to set the combination transmitter of the calling station to the combination representing the called station, or the receiver of the called station to that representing the calling station. In an alternative arrangement the two additional channels are not used. Instead the combination from the calling subscriber is modified by a preset signal and the modified signal is repeated a number of times. A counter counts these repeated signals to determine what signal is meant.

Title: Composite metal and foamed plastics units
IPC: E04C2/26
Filed: 1963-08-28
Abstract: 996,920. Laminates. OLIN MATHIESON CHEMICAL CORPORATION. Aug. 28, 1963 [Sept. 4, 1962], No. 34067/63. Heading B5N. A composite unit, which may be a structural member, is made by uniting two ductile metal sheets around a peripheral area leaving an inlet for the introduction of foamable material to the interior, and introducing such material in sufficient quantity that when it reacts to form a foam it deforms the interior portions of the sheets into a desired spaced relationship. In one embodiment (Figs. 6 and 7), three sheets are pressure-welded by either hot or coldrolling around edge portions and also in strips within the peripheral area, the intermediate unwelded strips 14 between one pair of sheets being staggered in relation to those 15 between the other pair of sheets, welding of these intermediate areas being prevented by the interposition of " stop weld " material. Thus when the outer sheets are deformed outwardly by the foamed material 19 the strips of metal between welded portions of the middle sheet will be pulled across to form stiffening ribs, as shown in Fig. 7. This element is stated to be suitable for wall structures and to provide insulation and sound-damping. The foam may be injected in with sufficient pressure to partially deform the metal sheets to form a chamber, completion of the deformation being by foaming pressure; the shape of the outer walls may be modified by constraining the sheets between platens. The metal may be aluminium alloy and the foam material a polyurethane, which may be mixed before injection or, alternatively, injected as two solutions, e.g. an isocyanate prepolymer and a solution of crosslinking agents such as polyols, a catalyst, and blowing agents such as chlorofluronated hydrocarbons, water or carbon dioxide. Other foam materials which may be used are polyethylene, polystyrene, polyvinyl chloride, copolymers of acrylonitrile, phenolic resins and polyesters. A preferred foaming composition is obtained by combining specified proportions of a prepolymer (representing 4À5 equivalents of toluene diisocyanate, 80 parts of the 2-4 isomer and 20 parts of the 2-6 isomer and 1.0 equivalents of a copropoxylated tetrol mixture of methyl glycoside and pentaerythritol of OH 435) with a similar copropoxylated tetrol mixture of OH 435, a silicone copolymer, fluorocarbon 11 and stannous octate. Specifications 759,804 and 759,831 are referred to.

Title: New monoazo dyestuffs derived from cyanuric chloride
Inventor: STEPHEN WILLIAM ELLIOT
IPC: C09B62/085
Filed: 1954-11-29
Abstract: The invention comprises dyestuffs, which in their free acid form, are of formula <FORM:0774925/IV(b)/1> where A may contain substituents other than OH and NH2 groups, R is H or alkyl and one of X1 and X2 is H and the other SO3H.  They are made by condensing equivalent quantities of cyanuric chloride and the appropriate naphthalene - azo - benzene dyestuff, preferably in an aqueous medium at below 5 DEG C. When the rate of reaction is slow an excess of cyanuric chloride may be used.  To avoid side reactions the dyestuffs are isolated at a pH of 6 to 8 and dried at 20-40 DEG C., preferably in the presence of buffering agents which maintain a pH of about 6.5 e.g. mixtures of disodium hydrogen phosphate with sodium or potassium dihydrogen phosphate.  The starting azo dyestuff may be made by diazotising 2 - naphthylamine - 4, 8 - or - 6, 8 - disulphonic acids and coupling them with appropriate primary or secondary amines e.g. in aqueous acid medium, or with N - (o  - sulphomethyl) - derivatives of the amines with subsequent removal of the N - o  - group by alkaline hydrolysis.  Specified amines are aniline, o- and mtoluidine and anisidine, 2, 5 - dimethyl - and - dimethoxy - anilines, 3 - amino - 4 - methoxytoluene and N - methyl - and -ethyl - aniline, - o - and m - toluidines, - cresidine and - m - anisidine.  The dyestuffs, as their alkali metal salts, yield orange colours on cellulosic textile material e.g. when they are impregnated with a solution of the dyestuff and after treated with an acid-binding agent such as caustic soda in an aqueous medium containing an electrolyte such as sodium chloride or sulphate or when printed with a paste containing the dyestuff and a substance such as sodium bicarbonate, which on subsequent heating or steaming liberates an acid-binding agent.  When R is an alkyl group the dyeings or prints show little shade change when dotted with alkali.  Examples are provided of the preparation of the dyestuffs and their use in dyeing cotton, cresidine being an amine used in addition to certain of those specified above. Specification 209,723 [Class 2(iii)] is referred to.
