Title: Ferrules on rope and strand
IPC: B21D53/58
Filed: 1971-06-21
Abstract: 1369211 Ferrules BRIDON Ltd 20 June 1972 [21 June 1971] 28974/71 Heading D1T A ferrule on a wire rope comprises a metal body compacted about a table, to cause the tube to grip the rope, and about a seal at one or both tube ends. Before compaction the inner tube part at least has a hardness less than that of the body and of the outer rope wires, and greater than that of each seal. An end ferrule on rope 1, Fig. 3, comprises body 3 compacted into tube 2 and onto seal 11 which flows into body cavity 4. The body is compacted, e.g. by waging or by pressing in a die set, so that circular ribs 7 are deformed to a polygonal shape to produce an uneven body-tube interface. The seal may lie wholly within the body, whose ribs may be omitted. The ferrule connecting ropes 1, Fig. 7, comprises a common body 3 compacted about a common tube and about two seals 11. The tube 2 of the end ferrule or connector may be formed, Fig. 9, from a castellated strip whose spine 2a extends along the tube axis, the tube being initially crimped around the rope. The tube may also be formed, Fig. 16, from an inner coil 21 of wire softer than the outer rope wires, and an outer coil 22 of wire harder than the ferrule body. The coils are dimensioned to grip the rope before compaction. During compaction the cross-section of the wires assumes a polygonal form. The body end is further compacted to retain seal 11. Three concentric wire coils may be used, the central coil being of wire of smaller diameter and softer than the wire of the outer coils. The tube may further be formed, Fig. 23, from a flat steel strip having oval holes, a plug being welded in one tube end. The body may be of plain carbon or stainless steel, or of a non-ferrous metal. The tube may be of copper, aluminium, mild steel or a semi-rigid plastic. The seal which is said to reduce fatigue stress of the body end, may be formed from an elastomer, a ductile metal or a composite material.

Title: Fault protection circuit for an electrical supply system
IPC: H02H3/33
Filed: 1973-06-19
Abstract: 1389529 Earth fault protection AMP Inc 19 June 1973 [28 Nov 1972] 29028/73 Heading H2K A system has its neutral earthed on the current source side of a protective device 30 responds to an oscillator including a transformer which has a primary winding 32 and its secondary windings comprise opposed main conductors 11, 12 which in the absence of an earth fault receive no oscillator signal. On the occurrance of a fault as at 26 the impedances of lines 11, 12 are no longer equal and oscillator current will flow in one of the lines. This changes the flux in the transformer core 37 and the charge in the impedance of the oscillator circuit reduces the current therein so that the voltage level at output of a peak voltage detector 41, 42 drops to make a unijunction transistor Q 2  conduct respectively to make an SCR21 conduct and energize a tripping coil 17 of a circuit breaker 15, 16, 18. The oscillator preferably operates at 20 kHz. The material of the core 37 may be such as to produce a response at this frequency rather than the 60 Hz system frequency and the core 51 of a balance protective system may be such that the latter responds at 60 Hz rather than at 20 kHz. The core-balance transformer secondary 53 is connected to an amplifier 55 one half cycle output of which breaks down a Zener diode 58 to cause a transistor Q3 to conduct and cause the oscillator to cease oscillation. If the amplifier 55 provides a signal on the other half cycle a diode 60 conducts the place the diode 41 in a blocking condition so that capacitor 42 dischages through transistor Q2 to effect operation the circuit breaker as above. Combinations of resistor 48 with compactor 49 and capacitor 42 with resistor 43 act as time constant smoothing circuits.

Title: An improved method of forming pipe or like connections adapted more particularly for use in connection with vacuum cleaning systems
IPC: F16L13/16
Filed: 1931-10-20
Abstract: 386,062. Pipe joints. QUEEN, H. E. and REPLOGLE, D. B., 2869, 28th Street, Washington, U.S.A. Oct. 20, 1931, No. 29149. [Class 99 (i).] In forming a connection between two tubular members of which one is formed of fibre or other hygrometric material, the end of the hygrometric member is moistened so that its diameter may be increased by a former and the enlarged end is allowed to dry either on the former before application to the other member or on that member after application thereto. By these means, fibre tubes may be joined to metal tubes or to other fibre sections especially if, in the latter instance, the fibre section has its diameter reduced by pressing its end into a tapering bore in a hot iron. The tube ends may be tapered and the tubes be initially of the same diameter. The separable joint thus formed may be made permanent by providing an embossment 21, Fig. 4, on the metal tube 19 over which a fibre tube 20 is contracted, the contraction forming a similar embossment thereon. In a modification, beads on the metal tube are engaged by the fibre tube when it contracts and a metal band, in a heated condition, is slipped over the joint to engage the fibre tube between the beads on cooling. A permanent joint is obtained by rivetting the overlapping portions with either a fibre rivet or by a plastic material such as that sold under the registered Trade Mark " Bakelite." In this latter case the rivet holes 25, Fig. 9, need not register exactly and the hole 25 in the fibre tube is counterbored at 251 to strengthen the joint.

Title: Process for the manufacture of cellulose
Inventor: BAYERL ALFONS
IPC: D21C3/02
Filed: 1960-08-24
Abstract: Cellulose is made by alkaline digestion of lignocellulosic material without preliminary hydrolysis, using an aqueous sodium hydroxide solution containing hemicellulose, and containing 1-13% by weight of sodium sulphide (Na2S), based on the weight of the sodium hydroxide. Solutions obtained in mercerising, containing 2-4% w/v hemicellulose, may be used, and the sodium sulphide concentration is desirably 4-10% by weight.  Dry wood is the preferred lignocellulosic material, and the weight of sodium hydroxide used may be 13-20% by weight based on the weight of bonedry wood.  The process may be effected in a single digestion phase, suitably using a sodium hydroxide solution of concentration not greater than 5% w/v, or in two phases, namely an impregnation phase carried out at atmospheric pressure and at a temperature below 100 DEG C., using preferably a sodium hydroxide solution of concentration 7-9% w/v, followed by a digestion phase, using preferably a sodium hydroxide solution of concentration not greater than 5% w/v, and in which after draining the pulp, hot water is added to restore the original liquor:wood ratio.  The impregnation liquor thus removed may be restored to its original concentration of sodium hydroxide, hemicellulose and sodium sulphide and re-used.  The pulp obtained may be used in paper making, or, after conventional chlorination and after-bleaching, for textile purposes.
