Abstract: ABSTRACT OF DISCLOSURE This invention relates to railway vehicles of the kind having at least two wheel-sets, each with a live axle mounted in a respective pair of axle bearings, at least one axle bearing of one wheel-set being elastically interconnected with at least one axle bearing of the other wheel-set through bracing means providing bracing between the wheel-sets. According to one aspect of the invention said bracing means comprise a frame structure for each wheel-set which extends transversely of the vehicle and is rigidly connected between axle boxes housing said axle bearings of its respective wheel-set, said frame structures being shaped and arranged so as to be connected together by said elastic connection at a level, which is below the axle height of the vehicle. Preferably said elastic connection is at a level well below said axle height, and a bolster is located within the space so provided. According to another aspect of the invention, the vehicle has side frames connected to respective axle boxes via a primary spring mounting and is characterised in that each said side frame is of fabricated construction comprising a bridge member of I-section from which a sub-frame depends, said bridge member and sub-frame defining a space therebetween into which respective side flanges of a bolster project, each said side flange being supported by the respective sub-frame via a secondary spring mounting. According to a further aspect of the invention, each said axle box is fabricated to provide a bearing support surface which is semi-circular or less, for supporting a cartridge bearing, and the cartridge bearing is rigidly fixed in position by a part-circular strap appropriately fixed on the axle box and tightened down onto said cartridge bearing.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for dispersing fine particle size carbon blacks in low density polyethylene whereby an initially prepared carbon black - low density polyethylene masterbatch, consisting of from 20-50 per cent by weight carbon black, is let-down by intensive mixing, in a dry blended mixture of low density polyethylene and high density polyethylene, or propylene polymer, to form an intermediate masterbatch, which is further let-down low density polyethylene by a second intensive mixing stage.  The proportions of each component are chosen to yield a final product consisting of (on a weight basis) from 1-5% carbon black, 1-10% high density polyethylene or propylene polymer, and at least 50% of the remainder being low density polyethylene.  The final products so obtained exhibit good carbon black dispersion on a micro-scopic basis and are essentially free of carbon black agglomerates, the type of which are usually formed by the more standard processes wherein the initial master-batch is simply let-down into low density polyethylene by only a single intensive mixing stage.

Abstract: CORE SPUN FILTRATION ROVING YARNS Abstract A low twist, high bulk filtration roving (4,15) is prepared by wrapping a sliver (6, 17) comprised of indi-vidual fibers, around a core (5, 16) in the conventional manner.  Exemplary of the bulk fibers (6, 17) which may he employed are naturally occurring fibers such as jute, cotton, animal hair; synthetic polymer fibers, such as acrylic, nylon, polyester, olefin, aramid, TEFLONTM; man-made organic fibers deriving from natural sources such as rayon or cellulose acetate; and inorganic fibers such as metal, glass, graphite; or a blend of two or more of these fibers.  Examples of the core (5, 12, 16), which can be continuous filaments, monofilaments or spun yarn, are one or more strands of the same composition as the fibers, or a combination thereof, twisted paper which can be plain, impregnated or metallized, and metal wire. Where the material is capable of being cast in film form, slit film may be employed as the strand(s).  The compos-ite roving (19) is wound upon a rigid perforated tubular center (22) to form a filter cartridge (18).

Abstract: ABSTRACT          A wind energy device uses an airfoil section to generate a vortex at its tip, thus concentrating the wind energy incident on the leading edge of the airfoil in the tip vortex.  To increase the wind energy in the vortex, a wind deflector is mounted close to the airfoil tip and is arranged so that it deflects wind incident on it into the vortex in a generally tangential direction and in the direction of rotation of the vortex.  A rotary device, preferably a Savonius rotor, is mounted in the path of the vortex so as to be rotated by the wind in the vortex, and drives an electicity generator.

Abstract: D-22,565C          TRANSFORMERLESS FAST-CURRENT LIMITER          WITH SYMMETRY CORRECTION FOR A SWITCHED-MODE POWER SUPPLY by John E. R. White ABSTRACT OF THE DISCLOSURE         A switched mode power supply employs a pulse width modulation controlled DC-to-DC converter to change a first voltage from a source of DC power into a regulated power source providing direct current at a second DC voltage.  A transformerless current-sensing device is adapted for connection in the path between said source and said converter and provides a control signal which is representative of the current flowing in said path.  A current-limiter control circuit is responsive to said control signal and provides an enabling output state when the sensed-current exceeds a predetermined value.  The enabling state overrides the pulse width modulator control and inhibits the converter, thus terminating the output pulse when the sensed current exceeds said predetermined value.

Abstract: ABSTRACT OF TEE DISCLOSURE In the cultivation of mushrooms from an underlying bed containing mushroom spores, novel compositions and pro-cesses are provided for a casing layer which is placed over the compost layer containing spawning mycelium.  A hydro-philic, thermosetting prepolymer resin is mixed in with a casing substrate, preferably Canadian peat, other optional additives and sufficient amount of water to form a slurry, and the mixture is allowed to cure to a spongy block.  The cured material is then pulverized and deposited as a casing layer over the compost layer.  Because of the high water retention qualities of this material, watering the mushroom beds is reduced by a factor of three or More, thereby reducing operation and production costs, as also the incidence and severity of disease and displeasing blemishes.

A first proportioning valve (76) controls communica-tion to the relay valve (84) which controls communication of braking pressure to the rear wheel service brakes on the towing unit.  The proportioning valve (76) is controlled by an inversion valve (90) which is responsive to the pressure level in the supply line (58).  When the pressure level in the supply line (58) is below a predetermined level indicating that the towing unit has been disconnected From the towed unit, the inversion valve (90) causes the proportioning valve (76) to proportion communication to the relay valve (84). A second proportioning valve (28) controls communication to the front wheel brakes of the towing unit and is responsive to the signal from the inversion valve (90) to proportion communication to the front wheel brakes when the towing unit is connected to the towed unit but which permits an uninhibited communication to the front wheel brakes when the towed unit is disconnected from the towing unit.  A third proportioning valve (34) controls communication through the service line (62) and is responsive to an operator actuated control valve (68) to provide proportioned brake ap-application on the trailer service brakes when the trailer is lightly loaded. A synchronizing valve (40) is responsive to the  magnitude of the brake application to reset the operator actuator valve (68) when higher pressures are generated, indicating that the towed and towing units have been recoupled.

Abstract: FLEXIBLE COUPLING     Abstract A lightweight, flexible coupling is provided by the present invention for transmitting torque and accommodating axial and angular misalignment between drive and driven shafts.  The coupling includes at least one reinforcing ring disposed between a pair of hubs or plates having anchoring means, wherein an elongated fiber strand coated or impregnated with a flexible matrix is wrapped from the hub or plate on one side of the reinforcing ring(s), to and across the reinforcing ring(s) and then to the hub or plate on the opposite side of the reinforcing ring(s) following a geodesic path.  Torque applied to the coupling is thus transmitted between the hubs or plates solely through the fiber strands.
