Title: Improvements in and relating to earth leakage protection systems for electrical circuits
Inventor: CROWTHER FRED
IPC: H02H11/00
Filed: 1957-03-15
Abstract: 883,023. Protective cut-out arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 17, 1958 [March 15, 1957], No. 8639/57. Class 38 (5). In an earth leakage protective arrangement, such as that of Specification 675,514, in which arelay 9 is effective to prevent the closure or reclosure of a circuit-breaker 8 when an earth fault exists and in which the relay 9, a unidirectional current source 12, 13 and rectifying means 10 are connected in a local circuit between earth and one or more conductors on the outgoing side of the circuit-breaker, a half-wave rectifier 18 is connected so as to by-pass from the relay current originating from the conductors, e.g. due to capacity currents, arcing at the circuitbreaker contacts or the back e.m.f. of a motor 1, to avoid faulty operation of or damage to the relay. Auxiliary contacts 11 of the circuitbreaker 8 complete the local circuit when the circuit-breaker is tripped. The tripping of the circuit-breaker under earth fault conditions may be effected by energizing the relay 9 from a core-balance transformer (not shown). Alternatively a half-wave rectifier 19 may be connected between the supply neutral and the relay 9 so that the earth fault current is caused to flow through the relay. The relay 9 may be reset by means of a push-button switch 21 and a further relay or re-setting coil 20. In the latter case, the arrangement would be similar to that of Specification 860,430. In further arrangements, the local circuit may be connected to the supply conductors through star-connected resistances or inductances or through a resistance or an inductance. Reference has been directed by the Comptroller to Specification 658,823.

Title: Non-woven bonded fibrous fabrics
Inventor: GILLANDERS STEPHEN ROY
IPC: D04H1/50
Filed: 1963-03-06
Abstract: A process for producing a non-woven bonded fabric comprises the steps of laying a web of fibres a proportion of which are potentially crimpable synthetic fibres of length 1/8 to 1/2 inch and having a denier between 1 and 4, and treating the web to develop crimp in the fibres to the extent of 4 to 20 crimps per centimetre and 10% to 60% crimp, thereby consolidating the web.  Potentially crimpable fibres referred to are polyesters such as polyethylene terephthalate.  The web may include other fibres such as non crimped polyethylene terephthalate and natural or cellulosic fibres.  Bonding agents include fibrids of a fibre-forming polyester, cellulosic fibres or a coagulable elastomer or polymer.  The web may be formed by deposition of a slurry of the fibres together with the binder on the wire of a Fourdrinier or vat-type paper machine.  Crimping may be effected by heat e.g. during calendering, or by a chemical treatment.  The product may be used for heat and sound insulation wall coverings, packaging clothing fabrics and disposable napkins, or as a reinforcement in elastomeric material such as polyvinyl chloride or polyurethane to provide an imitation leather.  Treatment of the fibres to develop potential crimp may involve quenching the filament immediately after the spinning process with a thin layer of liquid or an air stream, alternatively the filament may be drawn over a narrow heated surface or a tow of filaments may be crimped, heated to set the crimp, cooled and tensioned and heated again and cooled under tension.
