Abstract: A fuel injector seal for preventing the intrusion of liquid fuel into the working moving parts of a fuel injector. The seal is in the form of a flexible bellows, assembled from first, inner and second, outer caps joined together. The seal is positioned in the injector to create a liquid tight seal between the reciprocating injector jet needle and the enclosure for the remaining fuel-sensitive components of the injector.

Abstract: Accumulators/compensators for pressurized fluent material systems are provided, in which a continuous substantially non-permeable, flexible membrane (like a bellows) surrounds or is surrounded by a non-gaseous support medium, all within a surrounding housing. Various combinations of support media, which may include internal gas-filled cavities, are described and illustrated.

Abstract: A PCI card is inserted through an I/O opening in a computer panel. On one edge of the card is a cover from one end of which projects a tab. A resilient gasket is attached to the panel to create a flexible EMC seal around the opening. Preferably the gasket is formed of tin-plated beryllium copper. The gasket has alternate staggered spring fingers oriented opposite to the direction of insertion of the PCI card. To retain the gasket the panel is formed with slots at either end and an outward struck projection at the middle. The gasket is formed with a tongue at either end to be inserted in one of the slots and a punched-out opening to receive the projection.

Abstract: PCI cards are plugged into vertical risers, the lower edges of which have been plugged into a motherboard. This involves a considerable force being applied to the riser card, both during insertion and removal, and may damage the card or the underlying motherboard. A support for the top edge of the riser card clips onto the upper end thereof. Rearward extensions of the support are gripped by tabs struck out of a wall of the enclosure.

Abstract: A computer housing or electronic apparatus frame (10) includes a compartment (12) that provides space for mounting a fan assembly (14) or similar component. The fan assembly (14) is mounted on a fan tray support (16), which is removably mountable within the computer housing (10) by means of the fan tray mounts (18). Fan tray mounts (18) are oriented facing one another so that side rails (22) of fan tray (16) are slidably received by the fan tray mounts (18). The fan tray mounts (18) further includes an elongated guide channel (31) that extends the length of the fan tray mount and is formed in the inside face (30) thereof. The fan tray mounts (18) also include a first, outwardly projecting stop (52) that is positioned inwardly from end wall (38) and a second, outwardly-projecting, resiliently-deflectable stop and latch lever (54) provided adjacent end wall (36).

Abstract: A structural foam, injection molded superstructure is attached to a motherboard by means of threaded inserts. The superstructure is formed with guide ways for CPU processor modules, and also for the edges of PCI cards. Features of the structure include cam levers on the CPU modules to install and extract the modules. A metal transverse vertical retaining bracket is attached to the superstructure to hold sides thereof parallel and prevent splaying of the free, open end of the superstructure upon extraction of CPU processor modules. The assembly provides stiffness to the motherboard.

Abstract: The amount of vitamin B.sub.12 in solution in a liquid is determined by mixing a sample of the solution with vitamin B.sub.12 -binding proteins from chicken serum in a pH of about 12.8 to 13.2, and then analyzing a component of the mixture. In preferred procedures, especially useful in assaying human sera, a competitive binding technique is employed utilizing labelled vitamin B.sub.12 and a buffer containing cyanide ion. By operating at very high pH and with chicken serum proteins, the assay can be conducted relatively simply and with very accurate results.

Abstract: A viewer for observing and measuring the diameter of diffusion rings occurring on immuno-diffusion plates employs a magnifying lens for observing the plate and a baffled back lighting system for illuminating the plate so that light diffused by the plate is visible through the lens against a dark field. A beam splitter supported between the lens and the plate superimposes an image of a pair of illuminated filaments on the image of the plate seen through the lens. Manual mechanism allows the spacing of the filaments to be adjusted by the observer to bring them to the diameter of a diffusion ring. A digital display connected to the adjustment system provides a read-out of the filament spacing and thus the diameter of the immuno-diffusion ring.
