Title: Multi terminal digital signal transfer system controllers
IPC: H04L25/38
Filed: 1973-10-23
Abstract: 1411720 Loop communication systems; digital transmission INTERNATIONAL BUSINESS MACHINES CORP 23 Oct 1973 [26 Dec 1972] 49241/73 Headings H4K and H4P Each terminal in a loop communication system incorporates an arrangement for repeating incoming signals in amplified form or for suppressing the information and replacing it with new information, the transmission line through the terminal remaining unbroken at all times. Coupling between the line and the terminal is effected by directional couplers which take the form of strip line transformers made up at circuit boards sandwiched between grounded copper sheets. Each signal traversing the loop 10 is sampled by a directional coupler 32. The sample is amplified and clipped by circuit 42 and then fed back in phase with the original signal on to the loop by a coupler 48. In this way power &c. failure in the terminal merely means that a signal on the loop is attenuated but not lost. Each amplified branched signal is also submitted via a coupler 58, a sawtooth generator driver 68 and a coupler 70 to the local terminal 14 which analyses the address portion of each passing 90 bit word. If the terminal desires to modify the word i.e. to transmit new information, it pulses out on wire 82 during the time slot occupied by its own address in the incoming signals. The first such pulse, a synch pulse, sets a latch 88 which starts a 90 step counter 90. Consequently the 90 bit incoming amplified branch signal, which is coupled via coupler 58 to wire 62, is gated through inverting amplifier 66 so that it may be applied to the loop via coupler 92 in opposition to the original signal. Delay lines 41 and 63 ensures that the just mentioned signals exactly coincide and thus cancel each other. Meanwhile the new information word is coupled to the loop via driver 99 and coupler 51 in place of the cancelled word. The signals on the loop are of sinusoidal format with one full period representing a 1 bit and absence of signal a 0 bit. Within the terminal sinusoids and rectangular pulses are used as is more fully explained in the Specification 1,410,842.

Title: Heat welding polyolefinic parts
IPC: B29C53/00
Filed: 1974-11-19
Abstract: 1492547 Seaming non-metallic sheet material WAVIN BV 19 Nov 1974 [27 Nov 1973] 50104/74 Heading B5K [Also in Division F2] In a method of heat welding a surface of one part of a polyolefinic material to a surface of another part of a polyolefinic material of a different melt-flow-index, substantially the same volume of material of each part is plasticized to form the weld. Preferably, the surfaces are heated for equal times by different amounts, e.g. 40-150 C., especially 50-90 C., above their melting points. The surface with the higher melt-flow-index is heated to a temperature 30-50 C. lower than the temperature to which the other surface is heated. In one embodiment, Fig. 1, pipe parts 4 to be butt welded are held by clamps 2, 3 one or each of which is or are movable towards the other. A welding assembly 5 comprises two aluminium heating members 6, 7 having internal heating wires 11, 11a and temperature probes 9, 9a cooperating with a current supply 10, 10a so that each member 6, 7 is heatable to a different temperature according to the particular polyolefinic material, the temperature being determined from a table compiled with data obtained from tests. A heat insulating member 8 is located between the members 6, 7. Plates (not shown) with scraping knives may be provided for cleaning the ends of the parts 4. The parts 4 are pressed against the assembly 5 under a compressive load which may be reduced or terminated after a time period and heating is continued. The assembly 5 is removed and the parts 4 are pressed together to effect welding. The members 6, 7 may have a polytetrafluoroethylene coating 14. Pressure is applied by a lever 12 which shifts the clamp 3 by a fork 13. An adjusting wheel 17 regulates the force exerted on the lever 12 by a pull rod 15 locked on a stand 16.

Title: Process for preparing high impact resinous composition
IPC: C08F279/02
Filed: 1963-12-20
Abstract: A process for preparing a high impact resinous composition comprises polymerizing 1,3-butadiene with a catalyst formed by mixing materials comprising an organometal compound and iodine or an iodine-containing inorganic compound, the polymerization being conducted in the presence of a monovinyl aromatic hydrocarbon or mixtures thereof at a temperature and for such a time that substantially none of said monovinyl compound polymerizes, and thereafter polymerizing said monovinyl aromatic compound in the substantial absence of non-polymerized 1,3-butadiene (i.e. not more than about 5% by weight of butadiene based on the monovinyl aromatic hydrocarbon). The polymerized butadiene has mainly the cis-1,4-configuration and the product of the invention is stated to be a homogeneous composition which contains a graft copolymer of 1,3-butadiene and the monovinyl aromatic hydrocarbon and homopolymers of the two respective monomers. The preferred monovinyl compound is styrene; various ar-methyl- and ethyl-substituted styrenes are also exemplified.  The organometal compound is preferably of the type RmM where R is an aliphatic, cyclo-aliphatic or aromatic hydrocarbyl radical, M is a metal and m is the valency of the metal; the iodine compound is preferably an iodide of an element occurring in Group II to V of the Periodic Table; the catalyst system for the butadiene polymerization may also comprise a chloride or bromide of a Group III to V element. Any unreacted butadiene remaining after polymerization thereof is removed, e.g. by flashing.  The monovinyl aromatic hydrocarbon is then polymerized, preferably in the presence of an organic peroxide catalyst, e.g. benzoyl peroxide, di-t-butyl peroxide or lauroyl peroxide.  The process may be effected batch-wise, or in semi-continuous manner wherein the polymerization of the butadiene is carried out in a first reactor or series of reactors and the polymerization of the monovinyl compound is achieved in a second reactor or series of reactors.  The product of the invention is desirably substantially freed from catalyst residues which result from the first stage of the process; this is usually achieved by treating the reaction mixture obtained after polymerizing the butadiene with a catalyst treating agent such as water, an alcohol, an inorganic acid or a mixture thereof, the agent and catalyst residues thereafter being removed, e.g. by decantation or centrifugation.  The compositions obtained are useful for preparing moulded articles such as toys, household utensils and mechanical goods.

Abstract: 1525490 Turbine power plant SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 15 Dec 1975 [31 Jan 1975] 51249/75 Headings FIG and F1Q A process for the generation of electric power comprises partially burning a sulphur containing fuel, cooling the combustion gases, removing hydrogen sulphide therefrom by absorption in an aqueous solution of a tertiary amine, and then burning further the gases to produce energy which is used to drive a power generating turbine. In the plant shown, air entering at I is compressed in compressors 2, 3 and supplied to reaction chamber 5 to support partial combustion of fuel supplied through line 4. The fuel may be a heavy oil consisting of a distillate residue of a mineral oil, e.g. propane asphalt, or a solid such as lignite, coke or coal which may be dispersed in residual fuel oil. Water or steam may be added prior to combustion. Some of the heat liberated in chamber 5 is used to generate steam in a waste heat boiler 6. The partially combusted gases leaving chamber 5 pass through a cooler 7 and a water scrubbing tower 8 from which carbon and ash are removed via line 9. The gases are then treated in a scrubbing tower 10 with an aqueous solution of methyl diethanol amine to remove hydrogen sulphide. The solution may include a solvent such as sulfolane, N-methyl pyrolidone or dimethyl formamide. The loaded solution is removed via line 11 to be steam stripped in column 21. The hydrogen sulphide thus liberated is passed via line 22 to a Claus plant 23 for conversion to sulphur. The cleaned combustion gases flow from tower 10 to a reaction chamber 13 where combustion is completed with air tapped through line 12, the gases then driving a turbine 14 connected to an electric generator. The exhaust gasses pass through boiler 15 to effect further heating of the steam raised in boiler 6, the steam then driving a turbine 17 before condensing at 18 and returning via pre-heater/cooler 7 to boiler 6. The methyl diethanol amine may be replaced by diisopropanol amine.
