For baby strollers, particularly umbrella strollers, a device to prevent tipping comprising a pair of rearward extension bars. Each bar is adapted to extend rearwardly over or nearly over one of the rear wheels of the stroller. Each curves downwards so as to clear the wheel over or near which it extends and then curves to present a distal end section at least approximately parallel to the surface on which the stroller sits. Each bar is provided with a clamp by which it may be attached to the stroller. The clamp is adjustable to optimize tip prevention and loosenable so that the extension may be folded transversely for storage or transport.

Stroller tip prevention

A method of processing a silver bromoiodide photographic element comprising contacting the photographic element with a color developer for less than 120 seconds; wherein the photographic element comprises a support and more than one dye forming unit, and wherein the dye forming unit closest to the support contains an electron transfer agent releasing compound represented by the formula:CAR-(L)-ETAwherein:

Method of processing a photographic element containing electron transfer agent releasing couplers

A composition for bleaching or bleach-fixing a silver halide photographic material has a pH of from 2 to 9. The composition comprises a bleaching agent which is either a persulfate or polyvalent metal complex of an aminopolycarboxylic acid, and from 0.01 to 2M of a sulfo-substituted carboxylate represented by Formula I

Sulfo-substituted carboxylates as buffers for photographic bleaches and

A composition for bleach-fixing a silver halide photographic element comprising a fixing agent and a ternary ferric-complex salt formed by a tetradentate ligand and a tridentate ligand and a method of bleach-fixing using said composition.

Photographic processing solution containing ternary ferric-complex salts

This invention provides a process for removal of silver halide from a silver halide photographic recording material by a processing solution with fixing ability (a fixer) containing thiosulfate as a fixing agent conducted in the presence of a thioether compound incorporated within a fixer formulation. It further provides a fixer formulation for use in said process. The fixer contains a maximum ammonium ion concentration of 0.9M.

Acceleration of silver removal by thioether compounds

A photographic bleaching or bleach/fixing composition contains a water-soluble ternary complex of an iron ion, a polycarboxylate ligand, and a second ligand which has at least one carboxyl group on an aromatic nitrogen heterocycle, such as a pyridinecarboxylic acid. Preferred materials are biodegradable, but all of the ternary complexes can be used in a variety of bleach or bleach/fix processes to good advantage as bleaching agents. They are particularly suitable for use in rehalogenating ferric chelate bleaches.

Photographic bleaching composition and processing method using ternary

This invention provides an accelerator for peracid bleaches used for bleaching silver halide photographic elements. The accelerator is a complex of ferric (Fe III) ion and a 2-pyridinecarboxylic acid or a 2,6-pyridinecarboxylic acid. The accelerator may be contained in the bleaching solution, a solution preceding the bleaching solution or in the photographic elements themselves.

Photographic peracid bleaches with ferric 2-pyridinecarboxylate and

A photographic peracid bleaching composition contains a peracid bleaching agent, and a water-soluble ternary complex of ferric ion, a polycarboxylate ligand, and a second ligand which has at least one carboxyl group on an aromatic nitrogen heterocycle, such as a pyridinecarboxylic acid. These complexes act as catalysts for the peracid bleaching agent. Preferred complexes are biodegradable, but all of the ternary complexes can be used in a variety of peracid bleaching processes to good advantage.

Photographic peracid bleaching composition and processing method using

A fixing solution having a pH.gtoreq.7 and comprising a fixing amount of sulfite and a fix accelerating amount of a thioether compound; wherein the fixing solution contains less than 0.05 moles/liter of thiosulfate and a method of processing an imagewise exposed and developed silver halide photographic element comprising fixing in said fixing solution a silver halide photographic element containing at least one emulsion or deposit of silver halide comprising greater than 90 mole % silver chloride.
