In a method of marking optically readable disc-shaped information carriers which are manufactured, for example, by a transfer-moulding process using at least one mould serving as a stamper, which mould has been derived from a master via at least two electroforming replication steps, the mould is provided with a marking for the subsequent indentification of the mould, which marking is situated in a...

Described herein is a method and system for sensing explosive fires by the parallel processing of signals derived from both electromagnetic radiation and mechanical wave energy simultaneously emanating from or near the source of these fires. This diverse-stimuli sensing capability enhances the false alarm immunity of the system.

An automated, self-contained apparatus for extracting meat from the appendages of crustaceans, such as crabs, the appendages having been severed from the body and cooked. The device includes a plurality of stations which recover and collect the meat in the appendages as well as dispose of the empty shell. The appendages are placed in radially extending recesses of a circular motor driven platter, ...

A device for peeling shrimps, of any reasonable size, that comprises a reservoir and a cover with one or more openings where tubular knife assemblies are positioned. Cooperating opening in the cover align with the tubular knife assemblies and allow the peeled shrimp through. A knife element is mounted on the inner surface of the tubular knife assemblies to remove the visceral parts of the shrimp.

A two component laser delivery system for surgical and endoscopic applications including a reuseable head portion for insertion into the laser generating apparatus and a disposable optic guide portion. The disposable optic guide portion is provided with a cylindrical retainer adapted to be received and locked into the reuseable portion. The reuseable portion includes a housing and a lens barrel, t...

A process and apparatus for ablating atherosclerotic or tumorous tissues is disclosed. Optical fibers direct low power light energy at a section of tissue to be ablated to cause the section to fluoresce. The fluorescence pattern is analyzed to determine whether the fluorescence frequency spectrum is representative of normal or abnormal tissue. A source of high power ultraviolet laser energy direct...

A static casting method for a hollow cast product using a mold with bottom comprising a top lid, a core and an outer mold section, the core being attached to the top lid and disposed inside the outer mold section. The outer mold section includes a lateral mold section and a lower mold section. The lateral mold section is formed at its inner peripheral wall portion with a composite cooling section ...

Films from aromatic polyesters and from aromatic polyestercarbonates are excellently suitable as electrically insulating films, for example as dielectric for capacitors and as conductor track films.

An apparatus (11) for inspecting the sealing surface (86) of a container (15) for dips, saddles and lean is disclosed. While the container (15) is rotated, a beam (77) of light is projected horizontally above and through a finish portion of said container. An optical detector (100) detects the height of said sealing surface (86) by detecting the location of a minimum in the light beam. Dips in the...

A system and method for optically measuring parameters including dry basis weight, basis weight and moisture content of fibrous sheet materials during manufacture without scanning. The system includes means for reflecting modulated light as parallel rays perpendicularly incident upon one surface of a traveling web, and means to detect light transmitted through the web at least at four distinct ban...

A direct memory access (DMA) system with a single bus architecture for controlling data transfers and storage between plural digital processors and plural Input/Output devices. Limiters are included for disabling access to the bus of a processor whose access time exceeds a predetermined time interval. A time governor is included to suppress processor access to the bus when total processor access t...

The lighting device of the present invention includes a regular ring shape lamp and a means of simple construction that controlls the direction of the light from the lamp to a predetermined direction, so that the light irradiates a predetermined part of an object to be inspected. Thus, it is used as the lighting device for an automatic inspection system for round edge portions of a circuilar shape...

A spring brake cylinder assembly in which a pushrod connectable to a brake assembly is extendable from an end of such cylinder housing the piston member. The spring brake cylinder further includes a clutch release mechanism for manually releasing the brake force being applied.

An electrosurgical knife includes a stainless steel blade whose surface is abraided or etched, a first coat of primer material applied over the blade, where the surface of the primer material is also abraided or etched, and a second coat of non-stick fluorinated hydrocarbon material applied over the coat of primer material to cover the primer material, for a total thickness of about three mils. Th...

Pneumo-hydraulic converter for disc brake callipers, particularly for commercial vehicles, comprising a body intended for application directly to a brake calliper or in the immediate vicinity thereof and having a central axis cavity in which there is sealingly slidable a first piston to which is fixed a second piston sealingly slidable in a pneumatic chamber formed at one end of the body and conne...

Polydiorganosiloxane compositions useful for producing flame resistant foam of the type containing finely divided nonmetallic fibrous heat resistant material and finely divided nonmetallic cellular heat resistant material tend to separate upon long time storage. The compositions remain homogeneous upon storage when at least 0.1 weight percent of fume silica is included in the composition during th...
