Patent GB-703252-A (GB)
Title: Novel copolymers and compositions containing the same
IPC: C08F2/00
Filed: 1950-07-26
Abstract: Copolymers of unsaturated aliphatic carboxylic acid esters or halogen substituted esters with alkenes or halogen substituted alkenes are prepared under such conditions that the fraction of the copolymers formed initially has an average molecular weight of less than 3,000 and an average ratio of carbon atoms, including the carbon atom of each carboxylic group, to esterified carboxylic groups of between 5 : 1 and 14 : 1, and maintaining conditions such that the fraction of copolymer formed in any subsequent small interval of time also has such an average molecular weight and average ratio of carbon atoms to esterified carboxylic groups. Unsaturated esters specified are the vinyl, allyl, isopropenyl and butenyl esters of formic, acetic, propionic, and butyric acids, chloroallyl acetate, ethyl acrylate, methyl methacrylate, ethyl methacrylate, ethyl chloroacrylate, and diethyl maleate. Alkenes and substituted alkenes specified are ethylene, octene-1, propene tetramer, allyl chloride, and methallyl chloride.  Alkenes containing more than one unsaturated bond may be employed.  The molecular weights of the copolymers may be kept within the desired limit by means of variations in the polymerization conditions, such as the use of high polymerization temperatures, polymerization in dilute solution, and the use of chain stoppers such as alcohols, aldehydes, such as valeraldehyde, diethyl ether, acetone, chlorinated hydrocarbons such as carbon tetrachloride and allyl chloride, chlorinated alcohols, aldehydes, and ethers, esters of chlorinated organic acids such as propyl chloroacetate, amines, nitro compounds, and mercaptans such as dodecyl mercaptan. The desired ratio of carbon atoms to carboxylic groups in the copolymers is obtained by charging the monomers initially in such a ratio that the copolymer formed initially has the desired composition, and thereafter maintaining the ratio of the monomer concentrations within the desired limits, and either stopping the reaction when the ratio of the monomers has attained a limit value, or adding the monomers periodically or continuously to the reaction mixture as they are used up.  The reaction may be carried out batchwise or continuously, in bulk, solution, or aqueous emulsion, in which case sodium mersolate may be used as an emulsifier.  Catalysts may be employed such as Friedel Crafts catalysts, peroxy compounds such as ditert. butyl peroxide, and a mixture of potassium persulphate and sodium sulphite in aqueous emulsion.  The copolymers are usually liquid and contain unsaturated linkages which may be hydrogenated with the use of a Raney nickel catalyst, or chlorinated.  The copolymers may be employed as plasticisers for vinyl chloride polymers or copolymers, or as lubricants in conjunction with oleaginous vehicles. Specifications 617,891, 666,530, 682,254 and 703,253 are referred to.

Title: Automatic telecommunication exchanges
IPC: G06F13/12
Filed: 1966-04-29
Abstract: 1,117,721. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 29 April, 1966 [6 May, 1965], No. 18858/66. Heading H4K. In a large exchange system which comprises a plurality of switching networks 1 which are controlled by a centralized, stored-programme data processor 9, a plurality of buffer circuits 13 are interposed between the networks and the processor. The buffers comprise wired logic including, e.g. a diode matrix, which is sufficient to allow them to perform certain elementary functions during call processing in addition to their normal purpose of inserting call data into a queue prior to its transmission to the processor or to the network. Examples of the functions controlled by a buffer are transfer of data regarding a calling line as signalled over wire 16 from a line scanner 6 to the processor; identifying a subscriber; operating certain switches; testing the condition of a called line; maintenance. General programme orders in respect of these functions are passed to the buffer from a processor. The orders are then stored and " split " by means of the wired logic into a sequence of operations. The sequence is performed, pausing if necessary to allow slowacting devices e.g. relays to operate, and when it is completed, the results of the order and any data obtained as a result thereof are reverted to the processor which can then initiate a new general programme order if required. Each buffer may execute several programme orders substantially simultaneously by interweaving the individual operations of the various sequences but if a sequence includes a set of two or more operations which must be performed consecutively, operations pertaining to another sequence may not be started until the set is complete. The current state of each sequence and any data relevant to it are stored in a ferrite memory. The buffers include logic for assessing the priority of the various demands for their services. Buffers and processors may be duplicated for reliability purposes. They may also operate in pairs which are taken into use alternately for processing-equalization purposes. Each switching network comprises cross-bars or remanent relays and includes a group of terminating matrices T to which lines and trunks are connected, a group of primary matrices G having junctors 3 wired across pairs of its outlets, individual group markers 4, 5, and a plurality of senders and receivers 7, 8 connected to the network intermediate its ends.

Title: Improvements in or relating to production of isopropyl nitrate
IPC: C07C203/04
Filed: 1955-06-30
Abstract: Isopropyl nitrate is produced by reacting isopropyl alcohol with aqueous nitric acid in the presence of urea in a cyclic system comprising a packed tower, circulating the reaction mixture through said tower by means of a pump, continuously introducing reaction components into the circulation conduit where also the heat required for the process is supplied, continuously discharging isopropyl nitrate and water formed in a gaseous state from the system, and continuously withdrawing liquid from the system to maintain a substantially constant volume of liquid in the system, and recovering the isopropyl nitrate so produced.  The reaction components are preferably added separately on the suction side of the pump, while the heat required for the process is supplied on the pressure side, from a heat-exchanger.  Preferably the circulation rate is such that the contents of the tower are changed 50-100 times per hour.  The temperature is suitably maintained below the boiling-point of the reaction mixture.  The vapours from the reaction tower are condensed and from the lower of the two layers so formed the ester is recovered.  Unreacted isopropyl alcohol may be recovered from both layers and recycled to the process.  A detailed example is given which also describes suitable apparatus.  Specification 696,489 is referred to.

IPC: B01J31/18
Filed: 1917-12-31
Abstract: 121,642. Wade, H., (Davis, D. I.). Dec. 31, 1917. Refrigerating, compression machines for.-In refrigerating-machines with multi-stage compression, a part of the liquefied gas to be employed as the cooling agent in a supplemental cooler or condenser is led into a passage or drum connecting the low and high stage compressors, to absorb some of the heat of compression. The refrigerant unvaporized in this drum or passage flows to the supplemental cooler and there vaporizes, the vapour being returned to the connexion between the compressors. In the arrangement shown, gas discharged from the high-stage compressor 19 passes through an oil separator 22 to the condenser 24, the condensed gas being collected in a receiver 25. The main portion of the refrigerant passes through a coil &c. in the supplemental cooler 18 to evaporators 4, 4<b>. A portion is branched off through a pipe 31 and expansion valve 32 to a drum 15 receiving gas from the low-stage compressor 9. Any liquid refrigerant in the drum 15 flows through a pipe 33 to the cooler 18 and there vaporizes, the vapour returning to the drum 15 by a pipe 17. A trap 5 may be placed in the connexion 6 between the evaporators and the compressor 9, so that unvaporized refrigerant may be returned through pipes 7 to the evaporators. An oil separator 13 may be placed on the discharge side of the lowstage compressor 9.

Title: Improvements in or relating to methods of producing electrical oscillations
IPC: H03B19/12
Filed: 1936-07-13
Abstract: 479,935. Valve generating circuits. BAIRD TELEVISION, Ltd., JOHNSTONE, D. M., and JONES, V. July 13, 1936, Nos. 19355 and 27286. [Class 40 (v)] A frequency-divider is so constructed as to produce a definite phase relation between the original current of basic frequency and the derived current of submultiple frequency. To this end the original impulses from the source are applied to a transmission channel and also to a known frequency-divider, the output of which is used to switch the transmission channel on and off so that some impulses coming from the source are suppressed while others are transmitted so as to form a sequence of impulses at the submultiple frequency, Fig. 1 (not shown). In the arrangement shown in Fig. 2, the original current is applied to the grid of valve 8 and the submultiple current is taken off the anode circuit at 12. Alternate impulses are suppressed by switching-impulses derived from the valve 10, which is controlled through a delay network 9. The switching-impulses may, however, be made long enough to suppress a larger proportion of impulses so that the frequency may be divided by a factor greater than 2. In the switching-device shown in Fig. 3, the valve 14 is back-coupled so that it is capable of oscillating when condenser 15 has been charged to a sufficient potential through the resistance or constant-current device 16, whereupon the condenser 15 is discharged through the valve 14. The original impulses consist of trains of high-frequency oscillations applied to the screening grid at 21, but alternate impulses, or some other proportion of impulses, are suppressed by the condenser potential not having acquired a sufficient value. The potential of condenser 15 is applied through a differentiating circuit 19, 20 to a valve 10. This valve switches a transmission device to which also the source impulses are applied. The transmission device may comprise a fourelectrode valve in which the switching-impulses are applied to the screen grid while the original impulses are applied to the control grid, Fig. 1, Provisional (not shown). Where the original impulses are television synchronizing signals, the derived impulses may be mixed with impulses derived from the A.C. mains and employed for control purposes as described in Specification. 472,686, [Group XXXV]. In a further modification, the transmitted impulses may be derived by submultiplication from impulses which have themselves been derived by multiplication from the switching-impulses.
