Title: Improvements in or relating to Wire Ropes.
IPC: D07B1/06
Filed: 1916-10-20
Abstract: 126,011. Wright, J. & E., and Taylor, T. A. Oct. 20, 1916. Wire ropes; flat-sided ropes; strands of special section, ropes with.-Relates to wire ropes, or strands therefor, of the kind composed of a number of straight-laid strands assembled and bound together, to give the desired cross-section. According to the invention, the strands are bound together by a series of wires helically laid within the interstices of the wires forming the strands. The strands a are composed of a central straight wire a', Figs. 3 and 4, and three outer wires helically laid about the central wire. A number of such strands are arranged parallel with one another to form the desired cross-section, for example round, triangular, rectangular, or elliptical, an additional central core composed of two seven-wire strands placed side by side being used in the case of elliptical ropes. Six such strands are shown in Fig. 6 arranged in triangular form. The assembled strands are then bound together by wires b, Fig. 7. which are helically laid within the interstices left between the wires of the strands a, so as to be practically flush with the latter and within the desired cross-sectional contour. An outer protective covering of one or more layers of coiled wire may be added.

Title: Manufacture of new condensation products, being more especially improved tanning agents and their application
IPC: C14C3/20
Filed: 1950-06-19
Abstract: Condensation products with good tanning properties are obtained by condensing in an acid medium formaldehyde, urea or thiourea and a polysulphone formed by heating under vacuum at 150-190 DEG  C. a monosulphonic acid of phenol, cresol or anisole; (see Group IV (b)). Dimethylol urea or similar condensation products may be used instead of free urea, thiourea and formaldehyde.  For each mol. urea or thiourea about 2 mols. formaldehyde are used and between 3 and 13, preferably between 4 and 6 mols. of phenol, cresol or anisole.  The condensation is performed at from room to boiling temperature, preferably 40-80 DEG  C.  The products are prepared for tanning by neutralizing with alkali and acidifying with an organic acid, e.g. formic or acetic acid.  Examples are given using polysulphones derived from phenol, anisole, raw cresol and o-cresol. Specifications 493,997, 504,994 and 595,211 are referred to.ALSO:Polysulphones for condensation with formaldehyde and urea or thiourea to produce tanning agents (see Group IV (a)), are made by heating monosulphonic acids of phenol, cresol or anisole under vacuum to a temperature of between 150 DEG  and 190 DEG  C., preferably 170 DEG  C.  The vacuum should be less than 20 mm., preferably 10-12 mm. pressure.  Condensation occurs with elimination of water derived from the sulphonic acid groups and nuclear hydrogen atoms. Examples are given of the sulphonation of phenol, anisole, raw cresol and o-cresol, with subsequent condensation of the resulting sulphonic acids under the stated conditions.

Filed: 1916-10-31
Abstract: 107,325. Etchells, T. W., Leach, R., and Roberts, H. Oct. 31, 1916. Warp beams.-Weavers' and warpers' beams &c. are provided with self-contained flange fittings, each comprising a sleeve member secured to the beam and a disk or flange member adapted to be mounted upon the sleeve and having parts coacting with parts on the sleeve member to enable the disk member to be firmly secured in operative position and readily removed. As shown, a sleeve member a is secured on a reduced part b of the beam and has a conical portion c, tapering to the full diameter of the beam, and a number of projections d adapted to register with slots g in the disk member f, so that, when the member f is placed over the sleeve and given a partial rotation, the projections d co-operate with cam surfaces h on the member f to force this member firmly against the conical portion c and correctly position the flange.

Patent GB-353148-A (GB)
Title: Process and apparatus for treating oils
IPC: C10G9/00
Filed: 1930-05-20
Abstract: In a continuous process for converting heavy oils into light ones in which the heavy oil is first distilled to form a condensate, part of which is cracked in a heated coil, the remainder of the condensate is introduced at substantially lower temperature (e.g. 55-65 DEG  C.) into the hottest point of the cracking coil to prevent undue decomposition of the oil.  Crude oil from a storage tank 1 is pumped through heat exchangers 7, 10 to vaporizing coils 12, 13 situated at the top of the furnaces 14, 15 and the products are led through a line 16 into an evaporator 17 terminating in a bubble tower 19.  The vapours passing off at the top of the tower through a pipe 20 are led to a condenser 21 and <PICT:0353148/III/1> the condensate is recycled through a line 75 as reflux.  The condensate collecting in a liquid trap 18 is directed through a cooler 30 to a receiver 31 from which a portion thereof is pumped through heat exchangers A, B, C and pipe 38 to the cracking coils 39, 40.  The remainder is pumped through a line 51 into the hottest portion of the cracking coils through valved inlets 52<1>, 52<11> and also into the transfer line 41 through an inlet 53<1>.  The cracked products pass through the line 41 into a reaction drum 42 or may be byepassed by a line 69 and thus flow through the heat exchanger C into a bubble tower evaporator 45, 46 similar in construction to the tower 19.  The vapours pass off through a pipe 47 to a condenser 48, the condensate being collected in a receiver 50 from which a part thereof may be recycled as reflux by the pump 78 to the tower 46.  The liquid residue in the evaporator 45 is pumped through the heat exchanger B to a storage tank 62, while condensate in the trap 70 is delivered through a cooler 56 to a tank 57 from which it is recycled through a line 58 for admixture in the pipe 34 with the condensate from the tank 31.  The coils may be cleaned from deposits by flushing them with water from a tank 63. The oil in the coils 12, 13 is heated to about 260 DEG  C., while in the coil 40 the oil is heated to about 480 DEG  C. but the temperature is reduced to about 425 DEG  by the addition of cooler oil.  The cracking temperature is attained in the coil 39, the coil 40 being heated to supply the endothermic heat of the reaction.

Title: Communication between redundant protection and safeguards logic systems within nuclear reactor power plants by means of light
IPC: G21D3/04
Filed: 1973-04-02
Abstract: 1428242 Nuclear reactor emergency control and safety WESTINGHOUSE ELECTRIC CORP 2 April 1973 [4 April 1972] 15689/73 Heading G6C [Also in Division H3] A nuclear reactor protection and safeguard system (Fig. 1) includes a plurality of sensors 24 to monitor reactor parameters and each to communicate an output to logic function assemblies along two similar, isolated trains 12, 14, the logic function assemblies acting to interpret the sensor outputs and, upon occurrence of a predetermined combination thereof, to activate control and protection mechanisms (such as shutdown rods, containment sprays and emergency cooling), and wherein electrical isolation is maintained between the trains 12, 14 which communication of logic information therebetween is possible, by means of light communication means in the form of, e.g. photodiodes or phototransistors. Physical isolation of the trains, also, is maintained by the use of coil-tocontact relays and the arrangement of wiring. The use of the two trains is based on the need to provide redundant logic, each train carrying the same information. Information sent to the reactor control room is encoded by redundant, synchronized multiplexers 34 and passed to decoders 36 via the isolation circuits 22. The isolation circuits comprise eight isolation circuits 38, 82-94 (Fig. 2), form per redundant train. The function performed by each circuit is similar to that of a two-input high-threshold NAND-gate. In the absence of error signals, the inputs I 1 -I 8  assume a logical zero state and and photoisolation devices are off. Upon the occurrence of a logical one at the respective inputs 52, 54 of an isolation circuit, e.g. circuit 38, a LED 60 becomes forward-biased to emit light which passes to a PN junction 62 via a clear dielectric which maintains electrical isolation. Detection of increased leakage from LSD 62 is accomplished by a current level detector 64 including an operational amplifier 50 which commences to provide a decreasing output voltage as a result of which transistors 74, 76 eventually saturate and cause a logical zero on line 78 which is the output of the isolation circuit 38.
