Granted: 1984-03-06
Abstract: ABSTRACT OF THE DISCLOSURE           A device for measuring both force and kinetic energy includes a first cylindrical tube with one end closed, which tube is positioned over a calibrated spring that has one of its ends adjacent the closed end of the first tube.  The other end of the spring extends beyond the open end of the first tube and is received within a second cylindrical tube mounted to slide over the first tube and having one closed end adjacent the other end of the spring.  For measuring kinetic energy an indicator member is positioned about the first tube in such a manner that it is displaceable by con-tact with the open end of the second tube during compression of the spring and remains on the first tube at the point of maximum displacement when the compression of the spring is relieved.  The position of the indicator with respect to the first tube is a measure of the kinetic energy that compressed the spring and the position of the second tube with respect to the first tube is a measure of that static compression force on the spring.

Abstract: "TUBE BENDER CONSTRUCTION"                ABSTRACT OF THE DISCLOSURE         A tube bender construction (10,110,210) for manual operation in bending a tube (T).  The tube benders include a mandrel (11,111,211) defining a bending groove (12,112,212) into which the tube is urged by a forming member (13,113,213) mounted to the mandrel to swing about a bending axis of the bending groove.  The tube to be bent is held against longi-tudinal movement during the bending operation.  Movement of the forming member about the bending axis is effected by manipulation of a pair of handles (17,18;117,118;219,220).          The handle connected to the mandrel is removably connected thereto as for removal when the mandrel is vise-mounted.          The tube clamping structure includes a hook (16,116,218) which is swingably mounted to the mandrel, and in the illustrated embodiment adjusting structure (130) is provided for adjusting the disposition of the swingable hook to provide a desired clamping force of the hook against the tube.  The adjusting structure includes, in one form, an eccentric pin (132) and structure (143) for locking the pin in adjusted positions.          In one form, the forming member (213) is swingably mounted to the form wheel (211) to be adjustable toward and from the form wheel groove (212) to accommodate variations in tube diameter and normal wear of portions of the tube bender during the life thereof  The form wheel defines a concave force transfer surface (242) having an improved engagement with the tube to be bent so as to effectively improve maintained tube roundness for effectively minimized stress formation in the bent tube.

Abstract: ABSTRACT        A transparent thin bottle shaped container is produced by means of biaxially oriented blow molding of a cylindrical piece with a bottom of polyethylene terephthalate material.          Multiple pieces are molded by every cycle of an injection molding machine.  The multiple pieces thus formed are held at the gate integrally projecting therefrom, by a base plate moved forward at the front of the mold in the injection mold-ing machine and then conveyed to a gate cutting unit provided to one side of the injection molding machine.  The pieces thus cut from the gate by the cutting unit are sequentially conveyed onto a conveyor.  The pieces are gradually cooled from the hot molded temperature during the conveyance and are additionally cooled, while being conveyed on an oblique conveyor installed with a cooler, to room temperature or lower predeter-mined temperature.  The cooled pieces are then re-heated by a heater immediately before a biaxially orientation blow molding process.

Abstract: Abstract of the Disclosure In the frequency control mode, a switch is ON.          A power difference is fed back to an adder through a limiter and is compared with an output from a power setter.  A difference signal from the adder is supplied to an adder to obtain a difference with detected power.          By the feedback loop, the preset power is set to be substantially equal to the detected power.  While the difference is greater than a predetermined value, an output from a level detector is at logic level "0".          Even if a mode switch instruction is received in this state, an AND gate does not produce an output signal and the mode changing is not performed.
