Abstract: A golf putter is formed with a clubhead including a striking face, added weight along the bottom at the rear of the clubhead to form a soleplate and weight added to the toe and heel portions. Secured to the back side of the clubhead is a weight support member. An elongated weight member secured to the weight support member is centered thereon and extends parallel to the striking face. In one alternative embodiment the weight is concealed in a cavity within the clubhead with its support member secured to a separate striking face member. In another embodiment, the weight member is faired into an open cavity open to the rear of the clubhead and spaced from the walls of the cavity.

Abstract: A golf putter is formed with a clubhead including a striking face, added weight along the bottom at the rear of the clubhead to form a soleplate and weight added to the toe and heel portions. Secured to the back side of the clubhead is a rearwardly extending support member. An elongated cylindrical weight member secured to the end of the support member is centered thereon and extends parallel to the striking face. Additional embodiments are shown wherein the elongated weight member is positioned high at the rear of the clubface, or supported on the soleplate. In one alternative embodiment the weight is concealed in a cavity within the clubhead with its support member secured to a separate striking face member. In another embodiment, the weight member is faired into an open cavity and spaced from the walls of the cavity.

Abstract: A golf club includes a clubhead having a striking face, a threaded cylindrical chamber behind and generally parallel to the face, and a threaded cylindrical weight member in the chamber. A hosel is attached to the cylindrical weight member and has a shaft receiving socket with a non-circular portion and a threaded portion, the shaft having a hosel engaging end with a mating non-circular cross section and a ferrule having threads engagable with the threaded portion of the socket. A second embodiment includes a clubhead which is symmetrical so that the hosel may be attached at either end to make the club ambidextrous. Some different structures for attaching the hosel to the cylindrical weight member provide for variations in the loft of the club. Another embodiment includes an asymmetric movable weight member which engages the head within a cavity therein and is adjustable both longitudinally and by changing the location of its center of gravity.

Abstract: A golf club includes a head having a striking face, a threaded cylindrical chamber behind and generally parallel to the face, a cylindrical weight member threaded in the chamber, a hosel attached to the cylindrical weight member having a shaft receiving socket with a non-circular portion and a threaded portion, a shaft having a hosel engaging end with a mating non-circular cross section and a ferrule having threads engagable with the threaded portion of the socket. An additional weight is adjustable in the chamber to provide the desired balance characteristics to the club. A second embodiment includes a head which is symmetrical so that the hosel may be attached at either end to make the club ambidextrous. Some different structures for attaching the hosel to the cylindrical weight member provide for variations in the loft of the club.

Abstract: A spinal rod coupler assembly providing four degrees of freedom for connecting a spinal rod to a vertebrae of a patient which includes a tubular coupler member, an eyebolt, an insert and a set screw. The coupler member has a longitudinal bore, a central axis, and an end portion that is open ended and internally threaded and a second end portion that is closed. A plurality of openings in the tubular coupler member that includes a first pair of openings intersecting the central axis of the bore at generally right angles and a second pair of openings intersecting the central axis of the bore at generally right angles. The first and second pairs of openings being perpendicular to each other. The first pair of openings are sized and shaped to receive a spinal rod. The eyebolt has a shank portion and an eye portion, with the shank portion being insertable through the second pair of openings of the coupler body. The eye portion has an opening sized and shaped to mate with a selected bone bolt or bone screw.

Abstract: A method of and apparatus for extending the memory capacity of a computer system having a rotating optical memory storage device and a fixed memory storage includes a scanner for accessing computer information and a rotating optical read-write memory device for storing computer information and for accessing and transferring computer information to and from the scanner and to and from the discrete memory storage of the computer system. The method includes the steps of storing computer information on a scannable storage medium, accessing computer information from the scannable storage medium, and transferring the computer information to the scannable storage medium or discrete memory storage of the computer system through the use of a multi-head rotating optical memory device. The scanner uses an optical laser scanning system to encode computer information on a physical medium. The rotating optical memory device uses virtual memory techniques to store and retrieve data for use at a required time.

Abstract: A boresight for determining the accuracy of a gunsight wherein a cartridge-shaped housing is dimensioned to fit within the gun chamber. A laser is contained in the housing. A switch is positioned in the end surface of the boresight housing to be contacted by the bolt face of the gun. The switch contains an indentation to receive the firing pin when the bolt face contacts the switch to activate the laser and illuminate a distant spot.

Abstract: Disclosed is a combination flexible cheek piece, stock cover, ammunition holder and pouch for long guns such as rifles and shotguns. The combination is designed to be held about the stock of a long gun by adjustable straps which hold the device securely on the stock of the gun. One face presents a cheek piece for the shooter. The opposite face presents a series of cartridge loops as well as pouch for holding small items. In one embodiment, a second pouch is secured to the top of the device to elevate the cheek piece, particularly for use with rifles carrying a telescopic sight. Hook and pile type fasteners are used for effective adjustable fit.

Abstract: A tilt or cant indicator for telescopic sights incorporates a gravity responsive device aligned with the reticle or vertical crosshair of the sight. A pendulum device incorporating a pointer is installed with its rotational axis intersecting the vertical crosshair such that canting is indicated when the vertical crosshair is not the pointer.

Abstract: An improved knife or bayonet scabbard of rigid material including a body and a clip. A swivel connection between the two allows limited rotation of the body with respect to the clip when the clip is extended for belt wearing. The body is restricted from rotation when the clip is realigned to an aligned position for inverted wearing as on the chest. The body includes an integral catch on one side of the blade receiving opening and an internal spring on the opposite side for biasing the blade of the knife toward the catch. An auxiliary flexible loop aids in holding the knife or bayonet in the scabbard.
