Title: Improvements in or relating to communication systems
IPC: H04L1/12
Filed: 1961-09-01
Abstract: 932,830. Error-detecting telegraph systems. SIEMENS & HALSKE A.G. Sept. 1, 1961 [Sept. 1, 1960], No. 31519/61. Class 40 (3). In a communication system binary coded message signals are transmitted in groups. A first characteristic signal is derived from each group as transmitted and a second from the group as received. The receiver returns the second signal to the transmitter where it is visually compared, e.g. after punching a tape or printing, with the first signal. Lack of identity indicates an error in transmission. The comparison may, in addition, be performed at the receiver. In the embodiment described, a calling signal from the transmitter sets the distant receiver to its receiving state and the local teleprinter ready to print the message transmitted. The group of message signals is transmitted and is printed by the local printer and by the receiver. Evaluating units at the transmitter and receiver derive the first and second characteristic signals, e.g. by counting the number of space signals in the group. At the end of the transmission of the group a switch is operated which causes a termination signal to be transmitted. This causes the signals from the evaluating units to be printed at their local printers and to be transmitted to the other station, where they are printed. Thus at the transmitter printer there appears both the first and the second signals. This permits visual comparison for detection of error. The transmitter is automatically set ready for transmission of the second group of signals after the receipt of the second characteristic signal, or at a predetermined time after the end of transmission of the first group if no second signal is received.

Title: Process for applying thermoplastic coating to interior surfaces of articles
IPC: B29C48/09
Filed: 1959-09-18
Abstract: <PICT:0876549/III/1> Thermoplastic coatings (e.g. polyethylene, nylon) are applied to the interior surfaces of tubular articles, e.g. of metal, cellulose or synthetic resin, by injecting a gas into a bubble of the molten thermoplastic material while it is being extruded, the bubble being positioned within the article to be coated which is moved in the direction of flow as the article receives the extruded blown melt from the extruder.  In an illustrated example, thermoplastic material is moved through the passage 8 by the action of the extruder 1, thence through the annular die 7. Spacers 6, placed at intervals along the tube 5, separate it from the pipe 11 to be coated.  Extrudate is released through the die 7 in the form of a hollow tube which is sealed by pinching.  Air is then introduced via an air line 4 positioned lengthwise along the tube 5 and directed to a bore in the spider 12.  The pipe 11 is moved in the direction of the extrudate flow and the extrudate is forced against the inner wall of the pipe 11 by the injected air. When the coating is completed, the extrudate is pinched off on the forward side of the die, to allow formation of a bubble in preparation for repetition of the process. The coating material may contain fillers, e.g. titania, carbon and colloidal silica, and additives such as fumaric acid, and they may be treated with cross-linking agents, e.g. high speed eletrons, or organic peroxides, after application.  Metal surfaces may be primed with adhesion-promoting primers, e.g. those based on polyisocyanates. Specification 778,034 and U.S.A.  Specifications 2,695,255, 2,803,056 and 2,838,437 are referred to.

Abstract: 965,702. Aerials; pulse radar. A. C. COSSOR Ltd. Sept. 4, 1962 [Sept. 6, 1961], No. 32049/61. Headings H4A and H4D. In a secondary radar system of the kind wherein a group of " control " and " interrogating " pulses are radiated with respective non- directional and directional polar diagrams, the control pulse polar diagram is modified to have a hump 29, Fig. 3, or trough 29<SP>1</SP>, Fig. 4, over the arc embraced by the beam 27 of the directional polar diagram. In the embodiment, one mode of operation (mode A) is a control pulse followed by an interrogating pulse and the other mode (mode B) is a pair of interrogating pulses separated by a control pulse. The aerial system comprises a set 10 ... 15, Fig. 1, each member of the set consisting of eight unipoles 16, Fig. 2, and unipoles 18 and 19. Members 10, 11, 12, 14 and 15 are fed with interrogator pulses and member 13 is fed via a phase shifter # 0  and directional couplers DC4 and DC2. Unipole 18 is fed from box 21 via phase shifter # 0 , directional coupler DC4, a phase shifter # i  and a directional coupler DC1. Control pulses are fed via directional couplers DC3, DC1 to unipole 18 and a small part of the energy is fed through a phase shifter # C  and coupler DC2 to member 13 and through phase shifter # C , coupler DC2 and a phase shifter # CB  to unipole 19. Phase shifter # 0  is adjusted such that the energy reaching member 13 is in phase with that reaching members 10, 11, 12, 14 and 15, and phase shifter # i  is adjusted such that the energy at 18 is in phase with that in the members 10. . . 15. The desired shape of radiation pattern during control pulse emission is obtained by adjustment of phase shifter # C  : in mode A, the pattern 28, Fig. 3, is arranged and in mode B, the pattern 28<SP>1</SP>, Fig. 4. Phase shifter # CB is adjusted to minimize energy feed to unipole 19 during interrogating pulse emission. In a modification, unipole 19 is fed directly from the control pulse input 24 via an attenuator. All the components shown in Fig. 1 are mounted on the aerial boom.

Title: Improvements in or relating to catalytic processes
IPC: C07C2/68
Filed: 1947-12-06
Abstract: Aromatic hydrocarbons are alkylated with olefines in the presence of aluminium chloride as catalyst, the aluminium chloride being introduced into the reaction zone in the gaseous phase in an amount of not more than 2 per cent, preferably 1 per cent, by weight of the reactant feed.  Inert gases such as nitrogen, hydrogen, methane or ethane or a reactant in the vapour state may be used as diluents for the introduction of the catalyst.  The process is most useful in liquid or mixed phase reactions, e.g. in the production of ethyl benzene from ethylene and benzene. Preferred aromatic compounds are benzene and toluene and olefines instanced as particularly suitable are mono-olefines containing 8-16 carbon atoms in the molecule, e.g. trimers and tetramers of propene and dimers, trimers and tetramers of butene.  Reaction temperatures instanced are below 200 DEG  C. and pressures not over 50 atmospheres and generally below 20 atmospheres are employed.  A catalyst promoter, preferably hydrogen chloride, may be used in an amount of preferably not more than 2 per cent by weight of reactants fed.  In an example, a feedstock of toluene and octene-1 is scrubbed with hydrogen chloride recovered from a previous working of the process, admixed with unreacted recycled olefine and aromatic, preheated to reaction temperature, admixed with further quantities of recycled hydrogen chloride and treated in the reaction zone with aluminium chloride introduced therein with heated inert gas and make up hydrogen chloride, the products and make up hydrogen chloride, the products of the reaction being stripped of hydrogen chloride and fractionated to remove unreacted olefine and aromatic and further fractionated to separate mono-alkylated and poly-alkylated products, if mono-alkylated products are required the polyalkylated products are recycled and vice versa, it is stated that 2 volumes of toluene are reacted with 1 volume of octene-1 at 110 DEG  C. with an aluminium chloride addition rate of 0.5 per cent of feedstock to give a mixture of mono- and di-octyl toluene about 0.1 per cent of anhydrous hydrogen chloride being present as promoter and the liquid feed rate being 1.5 volumes per volume of reactor per hour, in (2) a propene trimer boiling in the range 120 DEG  to 150 DEG  C. replaces the octene used in (1), the reaction temperature is 98 DEG  C. and a table is given showing the effect of alterations in the feed rate and quantities of aluminium chloride and hydrogen chloride used on the olefine conversion and the relative proportions of mono- and di-nonyl toluene obtained.  The Provisional Specification covers the use of all aluminium halides in all quantities and includes catalysed reactions of aromatics with alkyl halides, iso-paraffins with olefines and isomerization reactions, e.g. m-xylene to o- and p-xylenes. Xylenes are given as additional aromatics to be treated and the olefins instanced for reaction with aromatics are particularly those having 5 to 9 carbon atoms in the molecule.
