Abstract: A golf swing timing trainer formed, in its preferred embodiments, from (a) a forearm brace that serves as a base for the other operative elements of the device; (b) a generally linear member, which member is pivotally connected to the forearm brace at one of its ends and has a vee shaped notch at its other end which fits against the shaft of a golf club held by the user when said club is cocked in the proper plane for a golf stroke; (c) an adjustable biasing means disposed between said forearm brace and said generally linear member, which biasing means generates an adjustable force proportionate to the angle between the forearm brace and the generally linear member/shaft such that the greatest force is experienced by the user when the shaft is cocked and the least is experienced by the user when it is fully extended; and (d) an audible signal generator that indicates when the shaft is not fully cocked.

Abstract: In accordance with the present invention there is provided an auxiliary battery charging terminal that may selectively engage battery charging circuitry inside a portable radio pager. There is provided a current conducting cap having a downwardly and outwardly flared rim that deforms to lock under the crimped edge an insulating seal ring of a standard rechargeable cell by application of a compressive axial force. The auxiliary battery charging terminal is further provided with a central tip axially projecting upwardly from the cap. The auxiliary terminal may be further provided with a cap of reduced diameter to circumferentially engage the raised battery cathode terminal on the battery cell. A mating recess in a remote battery charging receptacle may receive the tip to captivate the battery cell against lateral displacement. The tip may be further provided with a rounded apex to relieve localized frictional forces upon insertion and removal of the battery cell from the remote battery charging receptacle.
