Abstract: 1408902 Detecting faults in cables BRITISH INSULATED CALLENDER'S CABLES Ltd 27 July 1973 [27 July 1972] 35221/72 Heading G1U After a fault in a cable has been detected by a breakdown test, its location is determined by charging a capacitor C 1  to a voltage higher than the breakdown voltage from a high voltage D.C. source 4 and discharging it through the fault 1 via switches 14, 16 connected to the cable ends 11, 21. The capacitance C 1  must be larger than the capacitance across the conductors 2, 3 between which the fault has occurred. While the capacitor is repeatedly discharged through one end of the twisted pair telephone cable 2, 3, a search coil is moved therealong, which coil comprises an inductor 18 tuned to a frequency in the range present in the decaying discharge current, Fig. 3 (not shown). A large drop in signal level (e.g. 5:1) as shown on an oscilloscope 20 indicates the fault position. The position is confirmed by switching over the contacts in switches 14, 16 and repeating the search from the other end of the cable.

Title: Advanceable roof support assembly
Inventor: POTTS MICHAEL CHARLES
IPC: E21D23/26
Filed: 1963-09-06
Abstract: 1,023,478. Advancing mine roof supports. DOWTY MINING EQUIPMENT Ltd. Sept. 3, 1964 [Sept. 6, 1963], No. 35330/63. Heading FIP. Each of a series of advanceable hydraulically actuated mine roof support units 4, Fig. 2 (not shown) is associated with a first valve assembly A - - - F, Fig. 3 (not shown), which when actuated by pressurization of an advance-start line 42 connects a main pressure line 11 through valve c and a line 24 to the roof support advancing jack 7 and each support is also associated with a second valve assembly comprising non-return valves 35 - - 38 connecting said line 42 with a signal line 18 leading to the second valve assembly of an adjacent support unit; said second valve assembly, also including a control valve 41 which together with valves 35 - - 38 serve to prevent pressurization of the signal line 18 of the next unit to be advanced until the control valve 41 is operated. The closure member 44 of control valve 41 is unseated when prop resetting pressure in a line 49 displaces a piston 45 resulting in pressure in line 42 gaining access to a line 43, passing valve 37 and entering the signal line 18 leading to the next unit to be advanced. The member 44 may be unseated manually. The first valve assembly also includes a prop resetting valve 57 the closure member 58 of which is unseated by a trip-actuated piston rod 65 at the completion of a roof support advance resulting in jack pressure being transmitted through a line 62 to close valve F and open valve E whereby main supply pressure from line 13 is admitted through a line 25 and a non-return valve 27 to reset the props 6. Actuation of valves A - - D from the neutral position shown to the position required to extend the conveyer advancing jack 8 is effected by counterclockwise pivotal movement of linked levers 32, 33 which may be effected manually or by admission of fluid pressure to the underside of the operating piston of valve B from a line 71 containing a cutter operated valve (not shown). Valves A - - B are locked by 72 until completion of advance of jack 8 when member 72 is unlocked by signal pressure in line 42 which pressure also lifts the operating piston of valve C thereby closing valves A and C and opening valves B and D. Main supply pressure is thus admitted through valve D to lines 24, 30 to open valve F which allows release of props 6 prior to their advancement by jack 7. After completion of advance valve F is closed by pressure in line 62 and the props re-set which may be effected by manual operation of valve E which connects main supply line 13 to a line 25 leading to non-return valve 27 and the props 6 after which said main pressure in line 49 opens control valve member 44 to connect line 42 to line 43 and allow signal pressure to pass valve 37 and pass along the line 18 leading to the next roof support units to be advanced. Reference has been directed by the Comptroller to Specifications 943599 and 968277.

Title: Acrylonitrile polymer filamentary materials and process for treating the same
IPC: D01F6/18
Filed: 1956-11-22
Abstract: Filamentary materials consisting of polyacrylonitrile or copolymers or blends containing at least 70% of polyacrylonitrile and up to 30% of other polymerised mono-olefinic monomers, are placed in a closed chamber which is then evacuated and into which wet or saturated steam is introduced at a pressure within the range 30-60 p.s.i.g. and a temperature within the range 135 DEG -155 DEG  C. until the pressure within the chamber is within the range 30-60 p.s.i.g., whereafter the chamber is immediately vented to the atmosphere.  The above series of operations may be repeated one or more times.  After one or more such series of operations the chamber may be finally evacuated to cool the materials and remove excess water therefrom.  The filamentary materials may consist of a copolymer of 94% of acrylonitrile and 6% of vinyl acetate, or a blend of polyacrylonitrile and a polymer of an alkenyl-substituted N-heterocyclic compound.  The filamentary materials may also consist of a 94/6 acrylonitrile/vinyl acetate copolymer blended with sufficient of a 50/50 acrylonitrile/vinyl pyridine copolymer to give a product containing 3%-8% by weight of polyvinylpyridine.  A long list is given of other polymers which may be present in the filamentary materials in the form of blends or copolymers with polyacrylonitrile.  In an example, staple fibres consisting of a 94/6 acrylonitrile/vinyl acetate copolymer blended with sufficient of a 50/50 acrylonitrile/2-methyl-5-vinylpyridine copolymer to give a product containing 6% by weight of pyridine polymer, and formed by wet spinning, are placed in an autoclave which is then evacuated and into which saturated steam at 40 p.s.i.g. is introduced until the pressure in the autoclave reaches 40 p.s.i.g. The introduction of steam is then immediately stopped and the autoclave is at once vented to the atmosphere.  The above cycle is repeated 4 times except that the evacuation of the autoclave is eliminated between cycles.  The staple fibres are then removed from the autoclave and dried.  The process reduces the fibrillation to which wet spun polyacrylonitrile fibres are subject when in the form of yarns and fabrics and when subject to abrasion.  Specification 735,208 is referred to.
