摘要： This amplifier circuit for a magnetic transducer such as a magnetic head includes a pair of transistors which function both as write current modulators and read signal preamplifiers. The transistors are suitable for in situ deposition on a magnetic transducer carrier adjacent the winding, which keeps the signal lines of the data read by the transducer very short until amplification.

摘要： A helium transfer line adapted to be constructed in extended lengths and to carry liquid helium and/or 4.2.degree.K helium gas with minimum loss of refrigeration capacity due to heat leaks into and through the line. The transfer line, in its basic structure, comprises a fluid helium process line, radiation shielding, vacuum jacketing and a cryogenic coolant line in thermal contact with the radiation shielding and carrying a cryogenic coolant such as liquid nitrogen. Line components, comprising heat-stationed bayonets with or without LN.sub.2 bypass lines, expansion/contraction joints, and flexible sections and, if desired, valves, ell-sections and tee-sections, are designed to be integrated into the basic structure so that this structure may be carried through essentially the entire length of the line. Various combinations of these components in the transfer line make it possible to adapt the transfer line to a wide range of requirements dictated by such factors as space, and the relative positions of the two or more points of connection, i.e., a source of liquid helium and a refrigeration load to be cooled by the liquid helium.

摘要： The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

摘要： The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre bent rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

摘要： An apparatus including a base substrate including a reference voltage plane. A plurality of spaced apart printed circuit substrates are attached to the base substrate. Each one of the printed circuit substrates includes a reference voltage plane attached to the reference voltage plane of the base substrate. A system component is removably attached to a first side of at least one of the printed circuit substrates. The system component is electrically connected to the reference voltage plane of the printed circuit substrate. A support member is attached to a second side of each printed circuit substrate. Each support member is electrically coupled to the reference voltage plane of the printed circuit substrate. The support members are electrically connected to a reference voltage plane of the printed circuit substrate to provide a low impedance return current path for the electrical portion of the electromagnetic emissions, thereby reducing the magnitude of electromagnetic emissions.

摘要： An apparatus including a base substrate and a plurality of spaced apart end brackets attached to the base substrate. A plurality of spaced apart side panel assemblies are removably mounted between a mounting portion of each end bracket. A first edge of each side panel assembly positioned adjacent to the base substrate. A shroud is pivotally attached to each one of the side panel assemblies adjacent to a second edge of the respective side panel assembly. Each shroud is movable about a pivot axis between an open position and a closed position with respect to the respective side panel assembly. A shroud engaging portion is attached to each end bracket adjacent to each shroud. A engagement member of each shroud engages a corresponding shroud engaging portion when the respective shroud is moved from the open position to the closed position for moving the respective printed circuit substrate from an inserted position to a seated position with respect to the base substrate. Fewer components are required to construct the apparatus relative to previous apparatuses, reducing the cost and assembly. Furthermore, the shrouds function as a cam device for seating the system component assembly in the chassis.
