Abstract: A golf swing training device having a pair of unequal length golf club shafts connected end-to-end along a common axis. The shorter length shaft has a golf grip at one end thereof and a simulated plastic golf ball attached to its opposite free end. The longer shaft has a return bend therein adjacent the end thereof connected to the shorter shaft and a simulated or plastic golf ball attached to its opposite free end. The simulated golf ball on the shorter shaft is used to sight on a golf ball or target on the ground before the golfer when he addresses the grounded ball. The golfer then performs the backswing, the downswing and the follow-through in a practice swing during which the simulated golf balls should traverse the two planes desired for the golfer's swing and provide feedback to the golfer relating to his practice swing without contacting the grounded golf ball. The training club is suitable for practicing club swings for both so called "woods" and "irons".

Abstract: A spring locking device prevents any disconnection of connected female and male connector members of a connector. The locking device includes two pairs of bearings provided on both ends of a mounting flange of one connector member and locking members having support pins rotatably supported in the bearings. Each of the locking members is made of a springy wire and includes two parallel legs having lower ends outwardly bent, and support pins continuous to the lower ends to provide bent corners therebetween. When the locking members are mounted in the bearings, the bent corners are positioned inside of the bearings and in contact with bottoms of the bearings, and the support pins are in contact with semicircular edges of the bearings and extend therefrom out of the bearings on sides opposite to those of the legs. The locking device can prevent the support pins from removing from the bearings in a reliable manner with the aid of the particularly formed locking members without using removal preventing members.

Abstract: The certain quantity of light energy sufficient to effect lifelessness in each of a particular type of hairs, such as is found in a face, arm or back, is provided to the tip of a hand held probe each time a switch is closed, independent of the duration of the switch closure. This relieves the electrologist from having to manually count times, or the number of pulses of light energy applied to a hair body, to effect lifelessness therein. Such counting has been a major part of the photoepilation procedure, and a burden on the electrologist's faculties. In one embodiment, actuating a foot switch provides a series of timed and spaced pulses of light energy for a period, which is selectable by rotating a wiper of a variable resistor-capacitor circuit. The sum of the energies of the pulses over the selected period equals the certain quantity of light energy. In another embodiment, depressing one of four foot switches provides one of four fixed periods of light pulses.

Abstract: There is described a photomechanical method for forming pressure sensitive transfer reproductions of multicolor images upon a substrate involving the forming of a base coat protective layer on a substrate, applying one color ink on the base layer and a white ink overlayer on the color ink layer. The surface of the white ink overlayer is powdered and a layer of photoresist composition is applied. The photoresist covered layered substrate is exposed to a light source through an image carrying photographic negative film to harden the photoresist at the imaged areas forming a mask. Nonhardened photoresist composition areas along with their underlying layers are removed using stepwise solvent development steps. The steps are repeated for different colors with the final multicolor image being thoroughly dried and coated with a pressure sensitive adhesive to form the image transfer sheet. Drying between each step of formation is essential.
