An improved recessed sprinkler head including a frame having a base portion with an outlet to be connected to a source of water under pressure. The frame also includes a pair of curved arms which extend outwardly from the base portion and are connected together at a junction. The outlet is normally enclosed by a cap which is retained in position by a releasable mechanism that includes an element arranged to release when the sprinkler head is exposed to a predetermined elevated temperature. A dis...

A fast response sprinkler head. The sprinkler head includes a frame having a base portion connected to a source of water under pressure and a pair of arms extended outwardly from the base and are connected at a junction. A cap normally encloses the outlet in the base and a lever assembly, which extends between the junction and the cap, holds the cap in the closed position. The lever assembly includes a pair of lever members, with one of the lever members being biased in a direction away from the...

A partially concealed fast response sprinkler head having a body defining an inlet to be connected to a water line and having an outlet normally enclosed by a valve cap. The upper ends of a pair of lever members are supported on an internal shoulder in the body. Each lever member is generally semicircular in cross section and the lower ends of the lever members taper inwardly and define a central passage. The valve cap is provided with a threaded bore which receives a screw and the head of the s...

A sprinkler head including a frame or body having an opening to be connected to a water line. The body also includes a pair of arms which are joined together at a junction. A cap encloses the opening and a releasable mechanism, such as a frangible glass bulb, is connected between the junction and cap. When the sprinkler head is exposed to an elevated temperature, the glass bulb will fracture releasing the cap to permit water to be discharged from the opening. The sprinkler head includes an eject...

A time-temperature indicator device comprises a polymeric layer having a first and second surface and a dye composition adhered to said first surface comprising a dye which diffuses into the polymeric layer as a result of a cumulative time-temperature exposure wherein the polymeric layer is formed from a natural or synthetic rubber polymer or copolymer. The device may be attached to a product for monitoring cumulative time-temperature exposure.

Relief images can be formed in photographic elements having a tanning developing agent incorporated therein. The tanning developing agents have the formula: ##STR1## wherein R.sup.1 and R.sup.2 are each an alkyl group of at least 3 carbon atoms, or an aryl group, After exposure, the material is treated with an alkaline solution and unhardened areas are removed.

A bottom weather seal for doors comprised of independent, vertically moving adjacent blocks capable of engaging and sealing an uneven garage floor or sill. Each block has a vertically-running tongue on each side, which engages the vertically running tongues of each adjacent block, thereby providing a guide and seal for and with each adjacent block. Each block is moveably attached to a door by a screw attached to the door, and which passes through a pre-cut slotted opening cut in each block.

The present invention provides a method and system to improve the cookbook search algorithm used in a coding/decoding device or routine. The codebook search algorithm is performed by a processing system that allows for parallel execution of instructions, for example a DSP. An embodiment of the present invention provides a method for coding of a first waveform. First a plurality of vectors determined from a plurality of waveforms is stored in a memory. Next a minimum weighted error using a plural...

Photographic elements are disclosed in which exposure to at least one portion of the spectrum is recorded by a silver halide emulsion layer unit as an image having its optical density provided by silver. The layer unit is comprised of a plurality of radiation sensitive silver halide emulsion layers that are responsive to the same region of the spectrum, but differ in sensitivity, including a non-wandering silver halide reducing agent. A molar ratio of reducing agent to silver halide in one of th...

A method and apparatus for re-generating debug commands is provided comprising a source program having embedded debug commands in a first distinguishable field, and an assembler. The assembler operates on the source code extracting the embedded debug commands and associated address information from the source code while generating object code. The debug commands are stored in a command file for use during simulation. A simulator executes the assembled object code in conjunction with a debugger w...
