Title: Improvements relating to the sealing of electric conductors through tubular bodies
Inventor: YOUNG GEORGE SANGSTER
IPC: H02K13/02
Filed: 1952-09-30
Abstract: 710,322. Carrying conductors through partitions. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 15, 1953, [Sept. 30, 1952.] No. 24439/52. Class 36. A conductor 1 is sealed through a body 4<SP>1</SP> by bonding insulation 2 to the conductor, compressing the external surface of the insulation tc give it a smooth contour and axially compressing a collar 7 of yieldable, gas-impervious material betweer the smooth surface of the insulation 2 and the inner wall of the body 4<SP>1</SP>. The original insulation on the conductor 1 is removed at the region of sealing and the remaining ends scarfed, insulation 2 consisting of a solvent-less bonding agent, such as a polyester resin, and one or more layers of an insulating tape, such as woven glass, being bonded to the bared conductor and the scarfed parts of the original insulation. The conductor 1 may be of laminated form, the laminations being bonded together with a rubber-type adhesive, and if the conductor is of copper a protective layer of a coldsetting ethoxylene resin is applied to its surface prior to the polyester resin. After moulding the insulation to shape, a packing sleeve 3 and protective tube 4 are applied and the assembly inserted in body 4<SP>1</SP>. Insulating washer 5, resilient washer 6, rubber insert 7 and flanged insert 8 are applied, washer 5 resting against the inner end of a recess in the body 4<SP>1</SP>, and insert 8 being subjected to axial pressure. A compressible sealing ring 9 in an annular groove in the face of a steel ring 10 located on a reduced portion of the body 4<SP>1</SP> gives additional sealing.

Abstract: 1358350 Stable silanol solutions; polymerization of bis-methacrylates LEE PHARMACEUTICALS 24 May 1972 [24 May 1971] 24439/72 Headings C3S and C3P Stable solutions of silanols of the formula (HO) 3 Si(CH 2 ) n Y, wherein Y denotes an organofunctional group and n is 0 or an integer of from 1 to 3, are prepared by hydrolysing a silane of the formula X 3 Si(CH 2 ) n Y, wherein X denotes a hydrolysable group, and extracting the resulting silanol from the aqueous solution with a non-polar water-immiscible organic solvent in which the silanol is soluble. Suitable starting silanes are vinyl tris(2-methoxyethoxy)- silane, gamma-methacryloxypropyltrimethoxysilane, beta - (3,4 - epoxy - cyclohexyl)ethyltrimethoxysilane, gamma - glycidoxypropyltrimethoxysilane, gamma - mercaptopropyltrimethoxysilane, gamma - aminopropyltriethoxysilane, and N-beta-(aminoethyl)-gammaaminopropyltrimethoxysilane. Hydrolysis may be carried out with an acid or a base and the solvent solution is preferably neutralized after extraction. Suitable extraction solvents are ethyl ether, chloroform and methylene chloride. Uses.-For improvement of bonding of organic resins to mineral surfaces. Thus quartz, soda lime and glass bead fillers treated with the silanol solutions and subsequently with benzoyl peroxide give improved results when mixed with resin compositions based on a mixture of bisphenol - A - bis - (3 - methacrylate - 2 - hydroxypropyl)ether, triethylene glycol dimethacrylate ester, N - 4 - tolyl - diethanolamine and butylated hydroxytoluene. The above resin composition may also be applied to teeth previously treated successively with the silanol solutions and benzoyl peroxide.

A subscriber's set comprises a transistoroperated device adapted to receive oscillations from the exchange and to connect up an alarm if, due to a line fault, the oscillations are not received. As described, a transistor oscillator at the exchange generates supersonic oscillations which are received over the line by the subscriber's transistor which operates as an amplifier-detector whose output maintains a relay operated. Release of the relay sounds an alarm. The speech and supersonic circuits are separated at each end by filters. The oscillator at the exchange may be common to several subscribers' lines which it feeds cyclically appropriate modifications being made to the subscriber's receiving device. The oscillations may be of audio-frequency provided disabling means is applied when conversation is in progress. The oscillations may be amplitude modulated, the subscriber's apparatus then being provided with means for testing for the presence of the modulation.
