  • Patent number: 5143375
    Abstract: An inverted L-shaped finger support device is releasably secured to the back side of a putter, or other golf club, shaft adjacent to the bottom area of the handle grip. The attachment device is formed of unitary, or hinged, cylindrical stock with the short arm of the inverted "L" extending perpendicular from the club shaft and adapted to be positioned between the index finger and the middle finger on the right hand of a golfer. The perpendicularly extending portion is disposed in the groove of the first joint of the golfer's index finger during use to thereby permit essentially the entire weight of the club to be supported with this one finger. Tap screws, bolts and a spring clip structure provide alternate releasable connections for securing the finger support device to a golf club. The spring clip releasable connection permits forced movement of the device along the length of the golf club to provide vertical adjustment thereof when the golfer desires to employ a choke grip on the golf club.

  • Patent number: 4776595
    Abstract: A club swing indicator (10) to be used with a grip-improving glove (32) includes a thin flat base (12) having an approximate shape of the outline of a person's finger with a raised, relatively sharp, indicator element (18) mounted on one side thereof. The indicator is placed in a finger portion of the grip-improving glove and is oriented such that the indicator element impinges on the bottom of a person's finger which is in the glove. Thus, the indicator element is between the finger and a club gripped by the finger. Exceptional pressure between the finger and the club causes the indicator element to be thrust into the finger thereby causing a sharp sensation in the finger to indicate that the exceptional pressure has taken place.

  • Patent number: 4149938
    Abstract: An electrochemical detection device for detecting micro-organisms. A standard pH reference electrode and a platinum cathodic electrode are positioned in a container with suitable nutrient medium for microbial growth plus the sample to be tested. The two electrodes are connected to electronic circuitry including an up/down counter which counts up for the first 80 minutes after a test has been initiated. Then the potential between the two electrodes is tracked by the electronic circuitry and after there is a change of 10 mv a signal is sent to the up/down counter to cause it to reverse its count. Thereafter when there is a additional 20 mv change in the potential between the two electrodes another signal is sent to the up/down counter signalling it to stop. The resulting count on the counter is equal to the length of time for the inoculum to begin the production of measurable amounts of H.sub.2 after inoculation. This length of time is indicative of a endpoint.
