Title: Multi-layer fabric - comprises several textile webs laminated with thermoplastic adhesive
IPC: D06M17/00
Filed: 1972-03-01
Abstract: A molten thermoplastic adhesive is applied in an array of discrete areas, pref. by embossed applicator rolls, pref. to each face of a textile web. A facing web is then applied to each face of the textile web and the assembly pref. pressed together between applicator rolls. The adhesive is then allowed to cool, to harden it and secure the facing webs to the textile webt. The webs may be knitted, woven, non-woven or needled fabrics. The process can be carried out at web speeds of 30m/min and the use of a thermoplastic adhesive eliminates the process of heat curing the adhesive after assembly of the webs.

More particularly, FR-02A is effective against PPLO in chickens, pigs and cattle.  It is effective against mouse coccidiosis and the most prevalent types of chicken coccidiosis. It is efficacious subcu-taneously against M. galliscpticum air sacculitis in broil-ers, and orally effective in mice in systemic infections produced by Bordetella bronchiseptica.  Furthermore, FR-02A can be used as a growth promoting agent for animals such as chickens, pigs and cattle.

Abstract: MONITORING CIRCUITRY FOR A SKID CONTROL SYSTEM          Abstract:   A skid control system serves to control the opera-tion of a braking system for applying braking forces to a pair of spaced apart, independently rotatable vehicle wheels.  The system employs a brake control device which responds to a skid signal for controlling the braking system to release the braking forces on the wheels.  Wheel speed signals are provided by sensor circuitry and are representative of the wheel speeds of the first and second wheels.  Logic circuitry utilizes the wheel speed signals to determine an incipient skid condition of at least one of the wheels and, in dependence upon the determina-tion, provides a skid signal.  Monitoring circuitry is provided for use with such a skid control system for inhibiting the operation  of  the system.   The wheel speed sensing cir-cuits are monitored for sensor continuity and a control signal is provided when an open circuit condition is detected.  This control signal is employed to disable the skid control system.          Monitoring circuitry is also provided for monitoring the brake control, such as a valve solenoid, and for disabling the system when a determination is made of either an open or shorted solenoid coil.  Monitoring circuitry is also provided for moni-toring the time duration that a skid signal is provided by the skid signal logic circuitry and disabling the skid control system when the time duration of the skid signal is excessive.

Abstract: ABSTRACT          An electrode feed motor control circuit for an automatic electric arc welder which gives improved starting.  For cold starts, the electrode feed motor is instantaneously braked when the electrode first contacts the workpiece so that the electrode is lightly touching the workpiece and the electrode motor field is energized for pull back preparatory to the weld start.  For hot and cold starts, the motor speed more rapidly responds to transitional meltoff requirements.  The motor speed is automatically limited until the arc is fully established.

Abstract: ABSTRACT      An internal combustion engine having one or more compounded pairs of undulating volumes, such as produced by a piston reciprocating within a cylinder or tri-shaped  rotor orbiting within an epitrochordial shaped chamber, hereinafter, referred to for convenience as cylinders.  A total of eight cycles or "events" occur within paired cylinders which are located side-by-side in as close proximity as possible so as to share periodically common combustion and provided with combustible fuel mixtures prepared externally of the combustion chamber through conventional means, such as carburetion or jet systems.  The fuel-air mixture, when involving a petroleum type fuel, is positively programmed to be burned internally in two stages, the first burn at elevated temperatures is a fuel-rich, oxygen-lean mixture to minimize the nitrous oxides produced, and the second burn at lower temperatures is a fuel-lean, oxygen-rich mixture to substantially complete combustion of unburned hydrocarbons and oxidize carbon monoxide prior to being exhausted to the atmosphere.          To thus divide the combustion, the mixtures are not solely dependent upon stratified fluidic charges within each cylinder but paired cylinders communicate to form a common combustion chamber to effect the second stage burn and extended power expansion by differential displacement.  Both cylinders have inlet valves, only the second stage having an exhaust, a movable valve also being provided to allow communication between the cylinders at specific times during operation.

Abstract: IMPROVED SHAFT SUPPORT MEANS Abstract of the Disclosure The improved shaft support means described herein provides a means for resiliently supporting and damping the vibrations occur ing in a shaft in a turbo-machine or the like.  The bearings sup-porting the shaft are located in bores formed in the housing of the turbo-machine.  The shaft is oriented in an horizontal direction and the housing is split along a horizontal plane extending through the bore.  The upper portion of the bore is provided with a groove that is formed on a centerline coincident with the centerline of the bore.  The lower half of the bore is provided with a groove that is formed from a centerline located above the centerline of the bore so that the lower portion of the groove is of less depth than the groove of the upper portion of the bore.  An O-ring or the like is disposed in the groove encircling the bearing.  As a result, a greater force is exerted by the O-ring in the lower portion of the bore than in the upper portion of the bore so that compensation is made for the weight of the rotor and shaft assembly in the design of the turbo-machine.  Thus, compensation is made in the design of the turbo-machine for the weight of the shaft and rotor while at the same time providing resilient damping means to accomodate the vibrations of the shaft and rotor during operation.
