53241738, Jun 28, 1994

Filed:

Feb 5, 1993

Appl. No.:

8/014110

Inventors:

John R. Wick - Yardley PA

International Classification:

F04B 1700

US Classification:

417225

Abstract:

A hydraulic pressure amplifier has a hydraulic motor for driving a single cam and follower in a piston chamber. A number of conduits and chambers with automatically actuated valves controlling the flow between them are provided, such that, in operation, low pressure fluid introduced into the device to drive the motor will be automatically increased in pressure for discharge-.

International Classification:

B26B 1300

US Classification:

30 92

Abstract:

A cutter suitable for severing thick communications cable comprises a cutting lever member and a holding lever member pivoted to each other between their ends to provide, at one end thereof, a pair of opposed jaws. One of the jaws is in the form of a hook-shaped holding member having a concave nesting area for receiving the cable to be cut, and the other jaw is in the form of a cutting head having a cutting edge facing the nesting area and the cable. The cutting lever member has an integral handle at its other end, while a ratchetting lever member, with handle, is pivotally mounted on the other end of the holding lever member. The rim of the cutting head opposite from its cutting edge is toothed to form a gear segment which meshes with a drive sprocket wheel rotatably mounted on the pivot which mounts the ratchetting lever member. An automatically controlled pawl acts between the ratchetting lever member and the sprocket, and when engaged permits ratchetted advance of the cutting edge through the cable by angularly reciprocating motion of the ratchetting lever member within a predetermined range. Stop means lock the ratchetting lever member to the holding lever member when it is urged beyond its ratchetting angular range, to permit rapid opening of the jaws for receiving the cable and rapid closing of the jaws into contact with the cable preparatory to cutting.

Abstract:

A coin validating system typically used in a coin operated machine electrically couples a stationary coin to the tuning coils of an oscillator circuit. While the coin is in a stationary position and the oscillator is tuned to a first rest frequency, the output frequency and output amplitude of the oscillator is measured. The metal coin will increase the signal frequency from its rest frequency and will decrease the signal amplitude from its rest amplitude. While the coin is stationary, frequency and amplitude are measured and compared with expected parameters of a valid coin. If a match is made, the rest frequency of the oscillator circuit is changed. At the second test frequency, signal frequency and amplitude are measured and compared with expected frequency and amplitude parameters for a valid coin. Only if a match is made at both the high frequency and the low frequency is an accept gate actuated.

John R. Wick - Huntingdon Valley PA

International Classification:

B26B 1326

US Classification:

30250

Abstract:

Handle-operated shear-type cable cutter with one jaw member integral with one of its handles, the other jaw member being connected with the first by a main pivot about which said other jaw member rotates. An arcuate ratchet segment, integral with the rotatable jaw member, has ratchet teeth on a portion of its periphery remote from the cutting edge of the jaw. It is driven by a pawl assembly comprising a U-shaped bracket, the saddle of which houses a drive pawl and the legs of which carry, at their free ends, journals which support the main pivot pin and transmit thrust to the jaw members. A link member, pivoted at both ends, interconnects the operating handle with the pawl assembly. The cutting edges of the jaws are shaped to define an opening within the tips as the jaws meet, which is preferably diamond-shaped, but which reduces in size as the jaws close. A lost-motion pin-in-slot connection limits closing movement of the handles.
