Title: Method of bonding olefin copolymers to polyolefin fibres
IPC: D06M15/21
Filed: 1965-02-12
Abstract: Polyolefin fibres consisting of isotactic macronolecules have elastomeric, saturated and amorphous ethylene-alpha-olefine copolymers adhesively bonded thereto by applying directly to the fibres a mix of an ethylene-alpha-olefine copolymer containing a curing agent and a reinforcing filler and heating the whole to a temperature sufficient to vulcanize the copolymer mix without melting the polyolefin fibre.  The copolymer may be a copolymer of ethylene with propylene or butene-1.  The mix can be used as a foamed, spongy product.  The fibre may be formed from isotactic polyproylene.  The curing agent may be organic peroxides admixed with coagents acting as free radical acceptors such as sulphur, quinonimide compounds, furfural and derivatives thereof, maleic acid, anhydride.  The reinforcing filler may be carbon black, or mineral fillers.  The mix may be subjected to a thermo-mechanical pre-treatment prior to the addition of the curing agent.ALSO:Polyolefin fibres consisting mainly of isotactic macromolecules or articles obtained therefrom, have elastomeric, saturated and amorphous ethylene-alpha-olefine copolymers adhesively bonded thereto by applying directly to the fibres or articles a mix of an ethylene-alphaolefine copolymer containing a curing agent and a reinforcing filler and heating the whole to a temperature sufficient to vulcanize the copolymer mix without melting the polyolefin fibre.  The mix copolymer may be a copolymer of ethylene with propylene or butene 1 obtained by copolymerizing the monomers in the presence of organometallic compounds of aluminium e.g. AlEt3, AlEt2Cl and Al(iso Bu)3, and soluble or dispersed vanadium compounds e.g. VCl4, VOCl3, VAc3 where Ac is acetylacetone, and may have a Mol. Wt. of 50,000 to 500,000 and an ethylene content of 20 to 80% mols.  The mix can be used as such or in the form of a foamed, spongy product.  The fibre may be formed from polypropylene consisting mainly of isotactic macromolecules obtained through polymerization of the monomer in the presence of stereospecific catalysts consisting of aluminium organometallic compounds such as AlEt3, AlEt2Cl, and titanium compounds such as TiCl3.  The curing agents may be organic peroxides, admixed with coagents acting as free radical acceptors such as sulphur, quinonimide compounds, furfurol and its derivatives.  Other coagents may be maleic acid, maleic anhydride and other maleic derivatives. Reinforcing fillers may be carbon black or mineral fillers.  When a white mineral filler is used, the mix may be subjected to a thermo-mechanical pre-treatment prior to the addition of the curing agents.  Other additives may be used in the mix e.g. neutralizing substances for acidic fillers, dyes.  In Examples, fabrics for conveyor belts, satin fabrics and fabrics for tapestry are treated.

Abstract: 1,064,631. Brazing. GENERAL AERONAUTIQUE MARCEL DASSAULT, and OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. Feb. 14, 1964 [Feb. 16, 1963], No. 6327/64. Heading B3R. In bonding metal parts of a cellular core sandwich coherent layers of filler metal are interposed between the face sheets and core, the parts are uniformly pressed against each other and the assembly is heated in a hydrogenated and halogenated atmosphere. In making a sandwich comprising a cellular metal core and metal face plates, the core and plates are assembled with brazing metal sheets therebetween on a lower curved jig, a graphite cloth being provided on the jig. An upper graphite cloth is provided on the upper face plate and a stainless steel gas-filled cushion is arranged between the cloth and the upper curved jig. The jig parts are held together by ties (11), Fig. 1 (not shown). The assembly is placed in a box (7) in which ammonium fluoride and chromium is arranged and having a loosely fitted lid (8) and the box is supported on a hearth (3) in a refractory bell furnace (1) within a jacket (2) supplied with argon or nitrogen with hydrogen by tube (5). The assembly is heated to cause the ammonium fluoride and chromium to react and produce a reactive atmosphere and to melt the brazing metal. The gas in the cushion exerts a higher pressure than the reactive atmosphere to produce a differential pressure on the parts being brazed. The parts to be brazed may be of age-hardening stainless steel and the brazing metal may be 29% Ag, 71 % Cu. After brazing the temperature of the parts may be lowered to form martensite and may be annealed in the reactive atmosphere. In a modification the upper jig may be replaced by a flexible envelope secured to the top of the lower jig, this envelope being filled with the reactive atmosphere at lower than atmospheric pressure and in a further modification the flexible gas-filled cushion may be used above the gas-filled envelopes and below an upper jig. The parts to be brazed may be of nickelchromium alloy and the brazing metal may be silver, copper, palladium; silver, palladium; and nickel, chromium. In further embodiments a copper core is brazed to molybdenum or tungsten sheets using silver-copper eutectic brazing metal and ammonium fluoride and cobalt. A corrugated nickel-chromium core is brazed to nickel-chromium face plates using copper foil brazing metal. A stainless steel honeycomb core is brazed to nickel-chromium sheets using nickel-gold-palladium-chromium brazing metal and in a modification one face sheet is of molybdenum when gold-copper brazing metal is used. To a face sheet of refractory metal an outer copper sheet may be brazed at the same time or after the assembly of the sandwich.

Title: Method of manufacturing weld wires or electrodes from stable all-austenitic weld steels
IPC: B23K35/30
Filed: 1956-02-29
Abstract: Welding wires and electrodes are formed from stable all austenitic steels based on chromium-nickel and cobalt-chromium-nickel steels which have been deoxidized by one or more alkaline earth metals and/or one or more rare earth metals. In particular cerium, e.g. in the form of misch metal may be used in amount not exceeding 0.5 per cent by weight of the melt.  A preliminary deoxidization may be carried out with other deoxidizing agents such as manganese and silicon.  The steels used commonly contain niobium and tantalum as carbon binding elements and may also contain tungsten, molybdenum, vanadium and nitrogen. Constitutents which would tend to form ferrite in the weld metal, e.g. manganese in quantities of 6 per cent or more, should be avoided.

Title: Automatic-gain-control system
IPC: H04N5/53
Filed: 1962-02-20
Abstract: 970,672. Transistor automatic gain control circuits. HAZELTINE CORPORATION. Feb. 20, 1962 [March 2, 1961], No. 6529/62. Heading H3T. In an automatic gain control system, a first gain-control bias is derived from the input to the system, and a second gain-control bias is derived from the thermal noise present in the system in the absence of a signal. In a television a.g.c. system, the video signal is applied to the base of a control transistor 25 which is biased to conduct on signals extending beyond the blanking level and into the synchronizing pulse region. In order to minimize the effect of noise on the control signal output the collector potential is normally arranged so that the lips of the synchronization pulses occur near saturation, the stage becoming effectively a limiter as far as noise pulses are concerned. During the period of the synchronization pulses, however, the flyback pulse from the tube deflection system 18 is coupled to inductor 30 and increases the collector potential of transistor 25 so that it conducts more heavily on synchronizing pulses than on video noise impulses. The output from the transistor 25 is filtered and used to apply forward gain-control to the R.F. and I.F. stages of the receiver, that the gain of an amplifier stage, 11 for example, is reduced by increasing the voltage drop across a resistor 11b in the collector circuit. In the absence of a received signal, the control circuit 25 responds to thermal noise in the system to produce a residual bias for biasing the amplifier stages to maximum sensitivity. Specification 970,673 is referred to.

Title: Improvements in or relating to tippler devices for vehicles
Inventor: MITCHELL FREDERICK GILBERT
IPC: B61K7/20
Filed: 1948-03-04
Abstract: 651,522. Wagon-tipplers. BULK PRODUCTS, Ltd. March 4, 1948, Nos. 6826 and 19932. [Class 78 (iv)] A wagon 12, Fig. 1, supported on rails 11 on the cradle 10 of a rotary tippler is held in position by a stop 14 engaging the flange of the front wheel 21 of the wagon and by a stop 13 adapted to engage the flange 17 of the rear wheel 18. The stop 14 is pivoted at 22 to the fixed structure of the tippler and is normally supported by toggle links 23, 24 pivoted at 25 to the fixed structure. Upon movement of the cradle 10 to tip the wagon a member 34 on the cage bears against a lever 32 pivoted at 33 to the fixed structure so that the lever 32 moves to collapse the toggle 23, 24 withdrawing the stop 14. Thus when the cradle returns to the position shown the wagon runs out of the cradle and in so doing operates a lever 29, 30 to return the stop 14. The lever 29, 30 is loose upon the same shaft 28 as a lever 27 connected by a link 26 to the toggle 23, 24, and the arm 29 carries a lug 31 adapted to engage the lever 27. When the toggle 23, 24 is collapsed the arm 30 of lever 29, 30 rests against a stop with the arm 29 projecting above the track for operation by the front wheel of the wagon. When the front wheel of the wagon has pushed the arm 29 over, its lug 31 rests against the lever 27 with the arm 30 in position for operation by the rear wheel of the truck which depresses the arm 30 so that the lever 27 is turned to restore the toggle 23, 24 movement of which is limited by a stop 48. Means not shown then return the lever 29, 30 to its initial position. The stop 13 is pivoted at 15 to the fixed structure and carries a counterweight 16 so that it normally projects above the track but may be depressed by a wagon passing into the tippler. A spring device 20 limits the upward movement of the stop 13. In Fig. 4 is shown an alternative means for operating the stop 14. The stop is pivoted at 37 to the fixed structure and is connected by a lost motion device to an arm 43 so that as the tippler moves to tip the wagon a bar 44 on the cradle 10 pushes the arm 43 freely aside, but on return movement of the cradle the bar 44 depresses the arm 43 to move the stop 14 to the release position shown at 45. As the wagon passes from the tippler its front wheel engages an arm 41 on a lever 38 stiffly pivoted at 39 so that a link 40 pivoted to the lever 38 and to the stop 14 moves the latter to the position shown at 47. The rear wheel then engages a second arm 42 on the lever 38 to restore the stop 14 to the position shown in unbroken lines. Stops 14, 13 may be provided for the wheels on both sides of the wagon, and the distance between these stops is greater than the greatest wheel base to be accommodated. The stop 14 is reset by a wagon leaving the tippler before the front wheels of a wagon in contact with the first wagon have reached the stop. Specification 370,734 is referred to.

Title: An improved rotary harrow or cultivator
IPC: A01B21/04
Filed: 1934-03-03
Abstract: 434,811. Implements and machines for working land. NICHOLSON;, A. C., Trent Iron Works, Newark-on-Trent. March 3, 1934, No. 6853. [Class 6 (i)] A wheeled rotary harrow or cultivator comprises one or more pairs of rotatable shafts carrying radial tines, blades, or the like, the shafts of each pair being inclined to the line of draught in opposite directions and being coupled together so as to rotate in unison. The spikes may be arranged in four lines along each shaft. They may be so spaced along the lines as to produce oblique cuts distinct from or merging into one another. Shafts may be arranged at an angle of 45‹ to the line of draught and the spikes may be fastened to sleeves 25, Fig. 4, thereon coupled together by bevel gearing 30, a flexible shaft, universal joints, or other means. The shafts may be mounted in downwardly projecting parts of a triangular frame supported by three wheels. The front wheel 34 is a swivelling wheel and is adjustable vertically by means of a screw operated by a crank handle 36. The rear wheels 44 are mounted on arms on a shaft 40 and are adjustable by rocking the shaft 40 by means of a screw 47 screwing into a nut 48 on a pivoted bridle 49. The front sets of spikes 8 on the two sleeves 25 may mesh with one another, and the bevel gearing 30 may be dispensed with. In an implement in which two pairs of inclined spiked shafts are employed, one of the shafts of the rear pair is arranged behind the gearing connecting the front pair together, and the gearing connecting the rear shafts together is arranged behind one of the shafts of the front pair, so that no ground is left unworked. This implement has two wheels on an adjustable front draw-bar, and an adjustable wheel at the rear. In another arrangement comprising two pairs of spiked shafts, the spikes and shafts are so arranged that the two sets of bevel gearing are behind one another and a mutual scraping action is effected by the spikes of the two pairs of shafts. In the arrangement shown in Fig. 10, curved clearing bars 96 are provided between the sets of spikes. Instead of the spikes 8, longitudinal flanged plates 94, Fig. 12, may be bolted to the faces of a polygonal sleeve 92 mounted to rotate on a shaft 6, the plates being thin in the direction of rotation like the spikes 8. A spiral arrangement of the spikes on the shafts may be employed. The spikes may be shouldered and screwthreaded so as to screw into a polygonal sleeve. They may be flat and provided with a cutting edge directed longitudinally of the axis of rotation. A series of spikes may be produced from a pressing or disc 82, Fig. 21, the disc being deeply notched to produce arms or spikes 85. The arms may be twisted as at 87 and provided with points 88 and bevelled edges 89. A double-ended spike 90, Fig. 19, may be passed through a shaft 6 and secured by a set-screw 91. According to the Provisional Specification sub-frames carrying the spiked shafts may be connected together flexibly.
