Abstract: NON-METALLIC-REINFORCED MOLDED CROSSTIE            Abstract of the Disclosure A reinforced railroad crosstie formed by molding and bonding comminuted lignocellulosic material into a monolithic beam around a plurality of wooden reinforcing members which have relatively clear and straight grain, a high modulus of rupture and a high modulus of elasticity and are able to withstand a high amount of compression without crushing.  The reinforcing members are positioned within the crosstie proximate lines of maximum tensile stresses expected to be induced in the tie by different bending influences caused by passing trains and varying conditions of the underlying ballast.  The members are also positioned within the crosstie so as to avoid interference with the spikes employed to fasten the rail to the tie.

Abstract: METHOD AND APPARATUS FOR HANDLING THE FLUIDS IN A           TWO PHASE FLOW PIPELINE SYSTEM                   ABSTRACT OF THE DISCLOSURE    A method and apparatus for handling the fluids in a two-phase flow pipeline system.  The gas-liquid flow stream is fed into a separator in which the gas is separated from the liquid.  The gas is removed upwardly from the separator through a control valve.  The liquid is removed downwardly from the lower portion of the separator.  The liquid level in the separator is detected and a controller effects open-ing or closing of the control valve whereby the rake of flow of the liquid out of the separator is controlled.  An elon-gated accumulator is in fluid communication with both the liquid outlet of the separator and the outlet of the control valve.  The liquid flowing out of the separator is fed into the elongated accumulator loop which has previously been filled with gas.  A free piston is positioned in the accumu-lator loop ahead of the liquid to separate the accumulated liquid from the gas in the accumulator loop.  When a quantity of liquid has been transferred to the accumulator loop, selected valving is operated to supply pressure from a pressurized gas source, such as, the discharge pipeline of a gas compressor station, to the gas side of the free piston in the accumulator loop to drive the accumulated liquid back out of the accumulator loop and into a pipeline system, such as, the discharge pipeline of the compressor station.

Abstract: ABSTRACT OF THE DISCLOSURE           A vibration isolation system wherein a vibrating mass such as a helicopter rotor-transmission assembly is spring coupled to a body to be isolated, such as the helicopter fuselage, at a plurality of coupling locations.  Each coupling location includes a weighted lever arm pivotally connected to the vibrating mass and to the body and a coupling spring connected tot he weighted lever arm for transmitting the rotor forces of the rotor-transmission assembly to the fuselage through the pivot connections on the lever arm.  The coupling spring is in the form of an elongated spring arm connected at one end to the weighted lever arm and at the other end to the body through a pivot link, the latter being required to accommodate shortening of the spring during flexure.  The spring forces transmitted tot he fuselage through the coupling springs due to linear vibration forces are cancelled at the character-istic rotor frequency by equal and opposite inertial forces produced by the weighted lever arms.  A modified system is disclosed wherein spring forces transmitted to the fuselage due to angular as well as linear vibration forces are isolated. In this system a second coupling spring is added to the basic spring arm arrangement such that the second spring flexes only in response to either the linear or angular vibratory component, but not to both.  This causes the spring forces applied to the fuselage in response to angular vibration to be different from the spring forces establishes moment as well as linear force equilibrium such that the fuselage is completely isolated from angular as well as linear vibration.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for controlling the coating of wires, strips or the like, including wire expanded metal mesh, emerging from molten metal baths, involving subjecting the wire to an alternating electromagnetic field generated by a single phase alternating electric current supplied to an electromagnetic device which is at least partially immersed in the bath.  The field is applied at or below the point of emergence such that the point of emergence is always within the electromagnetic field to thereby control the coating weight per unit area.  The frequency and/or current for generating the field may be adjustable, and the field generated be either parallel or transverse to the wire, strip or the like.  The wire, strip or the like may pass through or adjacent, the electromagnetic device.  A neutral or reducing atmosphere may be provided within a chamber situated at the point of emergence and the point of emergence covered with particles inert to the environment.  Alternatively the emergence area, may be covered by a confined or unconfined bed of oil charcoal.  A similar amount of gas or vapour which will decompose to produce a sulphide ( - S) radical may be supplied to the protective atmosphere either directly or in addition to the neutral or reducing gas.

Abstract: ABSTRACT OF THE DISCLOSURE A method of making a semi-conductor heat sink mounting includes two extrusion steps.  Initially, a sub-stantially cylindrical copper billet having an upper cylindrical locating portion of reduced diameter is formed. A steel ring is then brazed to the copper billet such that it surrounds the locating portion.  The copper billet and the steel ring are then extruded to form a sink body portion, a pedestal portion extending upwardly from said body portion a defining a disc receiving recess therein, and a resistance welding ridge surround the pedestal portion.  A molybdenum disc is brazed into the disc receiving recess.  A stem is then extruded downwardly from the body portion of the heat sink mounting as a substantially evenly distributed downwardly force is applied to the heat sink body portion, the pedestal portion and the molybdenum disc.  This evenly distributed downward force prevents structural failure of the molybdenum disc by maintaining the disc in compression while the stem portion and the body portion of the heat sink mounting are worked to a full hard state.
