Title: Electric cable for medium and high voltage
IPC: H01B13/24
Filed: 1975-10-23
Abstract: 1516708 Cables INDUSTRIE PIRELLI SpA 23 Oct 1975 [27 Nov 1974] 43626/75 H1A An electric cable comprises one or more cores the or each of which comprises an insulating layer 13 extruded over a conductor 11, and a screening layer 14 extruded over and adhered face to face with the layer 13. The insulating layer 13 and screening layer 14 are each of synthetic polymeric material, that of the insulating layer 13 having been crosslinked by a chemical cross-linking agent that degrades the material of the layer 14, the surface of layer 14 that is in contact with layer 13 being degraded. The screening layer 14 includes an electrically conductive filler. During manufacture, the screening layer 14 is extruded on to the layer 13 as layer 13 is extruded on to the conductor. As described, an inner screening layer 12 is interposed between conductor 11 and layer 13, the conductor 11 being a plurality of wires (as shown) or a single wire. A single wire, as shown, may be enclosed in a tubular metal screen 15 and thermoplastics sheath 16, or a plurality of cores may be enclosed in a common screen 15 and sheath 16. The insulating layer 13 may be a cross-linked polyolefine, e.g. polyethylene, cross-linked copolymers of ethylene with at least one comonomer, e.g. ethylene-propylene, ethylenevinyl acetate, ethylene-ethylacrylate, or ethylene-propylenediene copolymers, or styrenebutadiene rubbers. Additives such as calcium carbonate, calcined kaolin or natural silicates, e.g. talc, may be added to modify the electrical characteristics. The cross-linking agent may be a mono- or poly-functional organic peroxide. Possible mono functional organic peroxides of the formula may be used, where R and R<SP>1</SP> are the same or different and are each an alkyl or alkaryl radical. Suitable bifunctional peroxides are those of the formula: where R<SP>11</SP> and R<SP>111</SP> are the same or different alkyl radical, preferably t-butyl, and X is a divalent alkyl, alkaryl or alkyne radical, specific examples being given. The screening layer 14 is preferably a copolymer of isobutylene with isoprene (i.e. a butyl rubber) with carbon black as the conductive filter. Other materials, e.g. halogenated butyl rubbers or blends of such rubbers or butyl rubbers with other saturated or unsaturated rubber such as ethylene-propylenediene terpolymers, ethylene-propylene copolymers, or ethylene vinyl acetate, may be employed which can be cured in known manner. Additives to the butyl rubber can be employed to facilitate peeling, e.g. low molecular weight polyethylene; paraffin wax, polyethylene oxide, silicone oils, metallic stearates, stearic acid and cetyl alcohol. The layers 13 and 14 are cured at the same time to adhere them together. The inner screening layer 12 may be applied by extrusion, or may comprise helically wound tapes of textile treated with electrically conductive material.

Title: Photo-electric drawing scanning device
Inventor: GAERTNER HERBERT
IPC: B23Q35/128
Filed: 1962-12-04
Abstract: 987,718. Photo-electric line followers. ADOLF MESSER G.m.b.H. Dec. 4, 1962, No. 45754/62. Heading G1A. A device for photo-electrically scanning the line of a template drawing for guiding a variablespeed cutting machine by means of a pair of photoresistors mounted on a rotatable arm, which projects with respect to the axis of rotation of its mounting in the direction of scanning, is characterized in that a second pair of photoresistors is provided on the arm, the distance of the first pair of photoresistors from the axis being proportional to the lowest and the distance of a second pair of photoresistors to the highest scanning speed of the device, the outputs of the two pairs being so connected to a control mechanism as effectively to provide a single output thereto which is infinitely variable between those of the two pairs of photoresistors. In the embodiment shown two pairs AB, A<SP>1</SP>B<SP>1</SP> of photoresistors are mounted on an arm rotatable about a point C and scan light reflected by a line 1 to be followed in the direction of the arrow 2. In such scanning systems the distances of the photoresistors from the point C or "lead" needs to be increased as the scanning speeds increase in order to allow for the reaction or delay time of the servo device controlling the rotatable arm and the cutting machine. The two pairs of photoresistors AB and A<SP>1</SP>B<SP>1</SP> are each connected in the arms of separate bridge circuits (Fig. 2 not shown) the bridge circuits being connected in parallel to the control device such as an amplifier feeding a servomotor and connected to a supply by means of a variable potentiometer so that the ratio of the signals from each pair of photoresistors is variable. This permits the effective "lead" of the scanning system to be varied between the limits of the distances of the two pairs of photoresistors from the point C by adjustment of the potentiometer.

Title: Derivatives of cellulose crystallite aggregates
Inventor: BATTISTA ORLANDO ALOYSIUS
IPC: G01N27/447
Filed: 1962-11-19
Abstract: Reduced cellulose crystallite aggregates, in which the potential aldehyde group in the 1 position of the end anhydroglucose unit of the crystallite chain is reduced to a hydroxyl group, and any other reducible groups on the chain are also reduced, are made by treating cellulose crystallite aggregates with a reducing agent.  Cellulose crystallite aggregates are the crystalline acid-insoluble portion of the products obtained by controlled acid hydrolysis of cellulose according to Specifications 879,945, 970,111 and 970,112. Specified reducing agents include sodium, potassium or lithium borohydride, sodium, magnesium, zirconium, aluminium or tin alkoxides, aluminuim ethoxide, aluminium isopropoxide, alkoxy magnesium halides, lithium aluminium hydride, sodium, sodium amalgam, aluminium amalgam, or zinc dust with acetic acid.  In a preferred method, sodium borohydride is added in successive small amounts to an aqueous dispersion of the aggregates, the temperature being kept at below 50 DEG  C., preferably at or near room temperature until further addition of borohydride no longer produces a rise in temperature, when excess reagent is destroyed by excess of acid.  Examples are given.
