摘要:
This invention relates to collet-type splices and collet-type dead ends and methods for splicing together two electricity transmission cables or terminating one electricity transmission cable, the cables comprising a composite core surrounded by a conductor. The collet-type fittings use a collet inside a collet housing to hold the composite cores without penetrating or otherwise weakening the core itself. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet and the composite core. The collet seats within the collet housing thereby holding the composite core with frictional forces. The design of the collet enables the composite core to stretch longitudinally through the collet to strengthen the frictional hold.

The present invention introduces a radically different way of accelerating biomolecule conjugates into tissue, and hence towards their targets for purposes of tissue staining. The invention provides for an order of magnitude improvement over the prior art diffusion process used to stain tissue. The invention comprises a method of tissue staining by applying an electric field to a tissue sample in the presence of an electrolyte and biomolecular conjugates of interest suspended in the electrolyte. Typical staining times are reduced to seconds as opposed to 30-120 minutes common in the prior art. The invention is also directed to devices for performing the method.

摘要:
A feeder for providing food to a plurality of animals comprises a generally horizontal base having a periphery. A central conical spreader is located above the base. An outer wall extends upwardly from said periphery of the base to an upper edge and defines a plurality of feeding apertures located to allow an animal to access feed located upon the base. A roof extends outwardly from the upper edge of the peripheral wall and over the feeding apertures. The roof defines a filling aperture located above the conical spreader. A door is adapted to selectively seal the filling aperture. Feed poured through the filling aperture is directed outwardly to the feeding apertures by the spreader to provide feeding animals with access through the feeding apertures to substantially all of the feed filled into the feeder.

An improved hydroformylation process involving reacting one or more reactants, such as an olefin, with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst, to produce a reaction product fluid comprising one or more products, preferably aldehydes; wherein said process is conducted in a region of the hydroformylation rate curve that is negative or inverse order in carbon monoxide, which is sufficient to prevent and/or lessen deactivation of the hydroformylation catalyst; and wherein total pressure is controlled at a predetermined target value and/or vent flow rate is controlled at a predetermined target value, by adjusting a flow of a carbon-monoxide containing inlet gas, so as to prevent and/or lessen cycling of process parameters, e.g., reaction rate, total pressure, vent flow rate, and/or temperature.

An apparatus for attaching a processor and corresponding heat sink to a circuit board includes a board member, a frame member mounted on the board member, a plurality of connector portions on the frame member, and a resilient load member. The resilient load member has a first end moveably connected to one of the connector portions and a second end forcibly connected to another one of the connector portions. A processor socket is mounted on the board member and a processor is seated in the processor socket. Forcible connection of the second end to its connector portion deforms the load member into engagement with the processor and urges the processor into the processor socket. A heat sink is mounted to the frame member and in thermal contact with the processor.

A processor extraction device interacts with a processor to extract the processor from coupling between connectors of the processor and a socket, such as land grid array connectors that are susceptible to damage from dragging or rotational movement during extraction. For instance, adhesive couples the processor to a load plate that closes over the socket to compress the processor in the socket so that the adhesive extracts the processor as the load plate moves from the closed position to an open position distal the socket. As another example, the load plate closed position compresses the processor onto springs that bias the processor out of the socket upon movement of the load plate to the opened position.
摘要:
This invention relates to collet-type splices and collet-type dead ends and methods for splicing together two aluminum conductor composite core reinforced cables (ACCC) or terminating one ACCC cable. The collet-type fittings use a collet inside a collet housing to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet and the composite core. After inserting the composite core into the collet, a compression implement compresses the collet. The collet holds the composite core with frictional forces and the collet further compresses and strengthens the hold on the composite core if the composite core pulls the collet further into the collet housing.

A system for aligning labels on label stock of different sizes with the print head in a printer is disclosed. The label stock is wound around a tubular core, which has a ring shaped groove in its inner surface at the midpoint of its length, forming a roll of label stock. The continuous liner strip contains synchronization holes and identification holes. The system includes a printer having a spindle mounted on a pedestal and holding the roll of label stock to be fed into the printer. The spindle is undersized relative to the tubular core and includes a ring shaped protrusion at its midpoint for engaging the groove in the inner surface of the tubular core. This roll of label stock is automatically maintained centered on the midpoint of the spindle, by its own weight, as it turns around the spindle as the label stock advances. The system also includes an optical detector movably mounted within the printer, for detecting synchronization holes and identification holes in the liner during print head traversal. The system includes a paper feed drive and a print head stepper mechanism. A controller within the printer receives signals from the optical detectors and converts the signals to commands to the paper feed drive and a print head mechanism to adjust for particular parameters.
