Filed: 1976-11-24
Abstract: 1537349 Cables INDUSTRIE PIRELLI SpA 24 Nov 1976 [5 Dec 1975] 49050/76 Heading H1A A cable having a plurality of insulated hollow conductors 1 is made by a process which avoids the absorption of ambient moisture in the course of production, which process comprises individually insulating each conductor 1 with lapped tapes 3 of insulating material to form a plurality of cores, each conductor having a central duct 2 extending longitudinally thereof, evacuating and drying each core and impregnating each core with an electrically insulating fluid, applying a tubular metal sheath 4 to each impregnated core, laying-up together the plurality of sheathed cores, and applying a protective layer 7 around the laid-up plurality of cores. In the described embodiment the insulating material is paper, which is impregnated with a fluid such as an alkylbenzene or a mineral oil. Reinforcing 5 such as metal tape covered with a sheath of plastics material such as polyethylene or PVC is provided over the insulating material. Screens of conductive material may be provided over each uninsulated conductor and over the unreinforced insulating material. The spaces between the cable cores can be filled with any suitable filler 6. The protective layer 7 can comprise metal armouring covered with bituminous material.

Title: Method and apparatus for the lateral strengthing of paper webs
Inventor: WALKER WILLIAM COMSTOCK
IPC: D21G9/00
Filed: 1964-12-03
Abstract: 1,030,079. Web winding arrangements. WEST VIRGINIA PULP and PAPER CO. Dec. 3, 1964, No. 49276/64. Heading B6B. [Also in Division D2] The coefficient of hygroexpansivity-i.e. the change in length per unit per percentage change in relative humidity x 10<SP>5</SP>- of paper or paperboard is decreased by passing the paper web before final drying around successive bowed rolls in tandem, the web initially contacting the inner concave surface of each roll and passing around the roll to the outer convex surface to cause the web thereby to stretch laterally. Each edge of the web is gripped at each bowed roll to prevent lateral slippage of the web by belts 40 mounted on pulleys 35, 36 on bracket 38, and on pulley 37 mounted on tension arm 39. The bracket 38 is supported on the end of shaft 30 of the bowed roll 22 and has slot 66 for the supporting screw enabling the bracket to be adjusted towards roll 22. More than two bowed rolls may be used. The bowed rolls are situated between dryer rolls and before or after a size press. The rolls may be bowed to a greater extent at the ends than in the middle. This treatment not only decreases the coefficient in the cross-direction but also in the machine direction, and also increases the stiffness of the paper.

Vinyl chloride is prepared from ethane by a process comprising the steps of: (a) reacting C1 2  directly with C 2 H 6  in contact with a finely divided inorganic solid at elevated temperatures to yield a gaseous reaction mixture of which the reactive ingredients consist predominantly of C 2 H 5 C1 and HC1; (b) passing the mixture of C 2 H 5 C1 and HC1 from (a) together with O 2  into contact with an oxychlorination catalyst to effect oxidative chlorination of said C 2 H 5 Cl to CH 2 Cl-CH 2 Cl; (c) thermally decomposing the CH 2 Cl- CH 2 C1 from (b) to produce CH 2  = CHC1 and HC1; (d) reacting C 2 H 6 , HC1 and O 2  in contact with a catalyst selected from siliceous materials, activated alumina, MnC1 2  supported on activated alumina, CaC1 2  supported on activated alumina, and LiC1 supported on activated alumina, at elevated temperature to produce a gaseous reaction mixture of which the reactive ingredients consist predominantly of C 2 H 4  and HC1, the HC1 for said reaction being obtained from the product of the thermal decomposition of CH 2 Cl-CH 2 Cl in steps (c) and (f) of the process; (e) passing the mixture of C 2 H 4  and HC1 from (d) together with O 2  into contact with an oxychlorination catalyst to effect oxidative chlorination of the C 2 H 4  therein to CH 2 C1-CH 2 C1; and (f) thermally decomposing the CH 2 C1-CH 2 C1 from (e) to produce CH 2  = CHC1 and HC1. Steps (b) and (e) may be carried out in a single reaction zone. Steps (c) and (f) may be combined in a single reaction zone. By-products obtained in Step (b) are trichloroethane, dichloroethylene and trichloroethylene.

Title: Improvements relating to monofilaments of polymeric organic material and their production and use
IPC: A46D1/00
Filed: 1965-11-24
Abstract: Brush bristles of synthetic monofilaments are treated to resemble natural bristles by dyeing to produce a dark peripheral zone and a central core of lighter colour and rounding, tapering or flagging the tips of the filaments to remove the zone and expose the ends of the cores.  The filaments may be dyed in the mass before spinning or the spun filament may be subsequently dyed.  In treating nylon filaments to give them the appearance of wild boar bristles for use in hair brushes, the filaments are immersed successively in dye baths of haematin and sodium bichromate, respectively containing acetic acid and sodium alkylsulphonate.  The black tips of the filaments are ground to produce rounded ends and to expose the yellow central cores. Filaments of polycaprolactam may be dyed using the same baths and blended with shaving brush bristles.  Corrugated filaments of polyethylene teryphthalate may be spun dyed with a ferro yellow pigment and dyed black superficially for use as a clothes brush. Polyamides such as hexamethylene sebacamide polyurethane, polyolefins or polyvinyl compounds and viscose rayon may be used as monofilaments.

[Also in Division F2] A fluid pressure regulator comprises a perforated flexible disc 19 provided with a lip 26 which distorts relatively to a member 25 to regular flow from inlet 12 to outlet 13. Member 25 is connected by a stirrup 23 to an arm 41 of a helical wading spring 40, the arm 41 being also connected by a stirrup 59 to a diaphragm 52 which deflects in response to outlet pressure to adjust the position of member 25. The outlet pressure is normally connected to chamber 68 soley through a port 72, but should the pressure down stream of closure 19, 25 exceed that in chamber 68, a resilient bonnet 74 is deflected to increase the flow area between chambers 68, 71. Diaphragm 52 is connected to stirrup 59 by means of rigid discs 50, 57, stud 61 and spring 63. With this arrangement should the pressure in chamber 68 become sufficient to damage the diaphragm, stud end 65 is pressed against casing 51 to move disc 57 away from the diaphragm so venting chamber 68 through passages 62, 69.

The signals S 2  may be produced by the generator 104, an auxiliary pulse generator and-a delay device. The auxiliary generator produces pulses which are added to the output of generator 104, the phase being controlled by the delay device.
