摘要:
A resilient battery separator, especially suited for use in a starved electrolyte battery, is made of an air laid fibrous mat of randomly oriented, entangled microfibers having a mean diameter between 0.5 and 2.0 microns. The air laid mat weighs between 50 and 450 g/m.sup.2 and has a thickness between 0.01 and 0.5 inches. The fibrous mat may be essentially uniform in density throughout its thickness or may include one or two relatively high density, high tensile strength fibrous surface layer(s) and a relatively low density, more resilient fibrous layer integral with and, in one embodiment, intermediate the two surface layers. The microfibers in the surface layer(s) are more entangled than the microfibers in the resilient layer. In a starved electrolyte battery, the separator has a thickness, when subjected to a loading of 1.5 psi, that is equal to or greater than the spacing between the electrode plates of the battery and, preferably, at least 110% of the spacing between the electrode plates of the battery.

A FED is provided comprising: an emitter located on a cathode; a pixel located on an anode positioned to receive electrons from the emitter; and a getter located on the anode. According to another aspect of the invention, a method of making an FED is provided comprising: depositing getter material over a tip on a cathode; assembling the cathode with an anode, wherein the getter is between the tip and the anode; and activating the getter, whereby the activation causes the getter to be deposited on the anode.

The bicycle seat pack comprises a clam shell structure wherein a top portion includes a releasably locking bicycle seat engaging assembly including a release lever. A zipper extending almost completely around a periphery of the pack allows for a drop down bottom portion to drop away from the top portion, allowing for easy access to the interior space, with enhanced accessibility allowing for compartmentalization of the inner space, if desired.

Packets containing a flowable material are provided with a draw-string or thread to squeeze the packet contents. The packet envelope is formed from a doubled-over web which gives the packet a folded-over edge and which encloses an intermediate portion of the thread close to the folded-over edge. The end portions of the web extend from the intermediate portion of the thread to extend through the opposite edge of the packet. The external ends of the thread are secured to a tag which is attached to the outer face of the envelope. The thread intermediate portion is retained close to the folded-over edge by heat sealing. Apparatus is also described for producing the packets in a continuous or semi-continuous manner.

A cryomagnet system, in particular for use with nuclear magnetic resonance (NMR) experiments or ion cyclotron resonance (ICR) experiments, with a low-loss helium cryostat (1) comprising a helium container (2) and one or a plurality of tubes for the feed or exit of helium into or out of the helium container (2), respectively, the tubes being sealed to the atmosphere outside the helium container (2) by at least one non-return low-pressure valve (4), wherein at least one exhaust pipeline (3) is provided with a device for dissipating the energy of the expanding helium. Such a device may consist of a chamber which is deviated from the exhaust pipeline (3) and has a wall material of very high extensibility, e.g. a folding balloon. Yet the device may also consist of a flow baffle which is provided in the exhaust pipeline (3), for example a porous disc (6). The device withdraws kinetic energy from thermo-acoustic oscillations of the helium gas column in the conduit system of the cryostat and thus dampens the detrimental oscillations which entrain increased losses of helium and disturbance of the magnetic field at the locus of the sample (FIG. 3a).

Fibres in a web are redistributed by ultrasonic vibration between two rigid members, for example to unite two webs together or to create a pattern of fibre orientation and fibre density; and preferably one of the members is a forwarding roll which forwards the web into a zone of increasing vibration in which fibres are bonded after redistribution.

Installer code is received from a network attached storage (NAS) system at a client device. The installer code executing at the client device performs a selected subset of administrative tasks at the client device, where the administrative tasks are tasks associated with the NAS system. The selected subset of administrative tasks includes installing a backup software component.
