A golf club stabilizing device adapted for attachment to a traditional golf club shaft is disclosed. The device includes a stabilizing portion which continuously contacts the golfer's lead forearm to enforce the correct hand positioning and swing mechanics. A variety of means for attaching the device to a golf club and for adjusting the position of the device relative to the golf club shaft are also disclosed.

Stabilized golf club

A narrow range of dinuclear spectral sensitizing dyes can be used in photothermographic silver halide emulsions without adversely affecting fog and speed levels with concentration variations.

Spectral sensitization of photothermographic elements

The addition of a class of compounds to a photothermographic emulsion reduces latent image fade.

Stabilization of latent images in photothermographic elements

Photothermographic emulsions may be stabilized against latent image fade and/or may have their speed increased by the addition of diazepines and fused aromatic diazepines.

Dry silver photo-sensitive compositions comprising an intimate mixture of a substantially light-insensitive silver compound which upon reduction gives a visible change and sufficient of a silver halide to catalyse said reduction to give a visible change in those areas where the silver halide has been exposed to light and when the mixture is heated in the presence of a reducing agent, and as a yellow acutance dye a 1-alkyl-4-nitro-methylene-quinolane, the alkyl substituent containing 1 to 4 carbon atoms.

Dry silver photo-sensitive compositions

Certain members of the class of odd-numbered methine arylidene dye bases are found to be of use in thermally-developable photosensitive compositions and thermally-developable photosensitive elements containing such agents. These compounds are acutance agents which are relatively stable against photo-bleaching but undergo thermochemical bleaching on heating in silver salt-containing thermally-developable photosensitive compositions.

Acutance agents for use in thermally-developable photosensitive

Photosensitive heat-developable dry silver sheet materials, containing organic silver salt and reducing agent and in which a minor portion of the silver salt has been halidized, are given an orders-of-magnitude increase in photographic speed by incorporating an organic sensitizing amide prior to halidizing.

Sensitizing a thermographic silver halide photographic material with

Certain thiazolidine- and thiazine-2-thione compounds, including 4-carboxythiazolidine-2-thione and 3,4-tetramethylene-4H,5,6-dihydro-1,3-thiazine-2-thione, and methods for preparing same are disclosed.
