Abstract: A computer cooling system provides a more efficient means of cooling, resulting in lower average temperatures and better reliability for the system. It comprises of a rotating baffle or set of baffles, and a formed enclosure. The enclosure accepts cooling fluid in a direction that is parallel to one of its walls. The enclosure is such that a recirculating airflow pattern is set up in its cavity. As the baffle rotates the direction of fluid flow reverses itself in the cavity of the enclosure. The turbulence created by such a system greatly enhances the rate of heat transfer on the components within the enclosure. The exact dimensions of the baffle, and frequency with which it oscillates will depend on the specific system.

Abstract: A hermetic electronic assembly incorporating cryogenically-cooled and air-cooled elements in an integrated assembly. A hermetic cryogenically-cooled enclosure is disposed in close physical proximity to one or more air-cooled circuit cards to minimize physical separation, thereby optimizing signal bandwidth and noise immunity. The air-cooled circuit cards, which generate substantial heat but do not require low operating temperatures, are thermally decoupled from the cryogenically-cooled elements to optimize cryo-cooler efficiency by reserving cooling capacity for the temperature-sensitive processor elements mounted within an evacuated hermetic enclosure. Thus, thermal isolation and physical/electrical proximity are preserved in the same package.

Abstract: An injection site platform for use in adding a needle-injected medication to a parenteral fluid being provided to a patient includes a base which has an outlet port of a size and shape to receive a needle-piercible resealable diaphragm. The platform consists of the base member and a port member and when these two elements are assembled together they apply a compressive holding force on the needle-piercible resealable diaphragm. The platform includes one or more sockets which are of a size and shape to hold a hypodermic needle sheath. The sockets each include a plurality of arms which are flexible so that the socket may hold difference size and shape needle sheaths.

Abstract: A keyless electronic combination lock is adaptable for placement on a door, and operates independently of any other locks and without a central control system. The lock has a keypad for entering combinations, a random access memory (RAM) into which the entered data is loaded, a microprocessor, and an electrically erasable programmable read only memory (EEPROM). One or more entry codes for opening the lock are stored in the EEPROM and loaded into the RAM when the lock is powered-up. To open the lock, one of these codes or a master entry code must be entered at the keypad. Each entry code can be individually prevented from opening the lock by entering a corresponding individual lock-out code. All of the entry codes can be locked-out by entering a master lock-out code, by entering all of the individual lock-out codes or by throwing a dead bolt. The master entry code works regardless of the lock-out status and regardless of the dead bolt. To change lock-out status, the lock-out code is simply reentered.

Abstract: An injection site platform for use in adding a needle injected medication to a parenteral fluid being provided to a patient includes a base and an outlet port of a size and shape to receive a needle piercable resealable diaphragm. There is a conical wall which connects the outlet with the base, with the smaller diameter portion of the conical wall being integral with the outlet and the larger diameter portion terminating at the base. The conical wall provides a needle guide to the diaphragm positioned in the outlet and access for the application of an antiseptic wipe to the diaphragm. A portion of the platform has an opening for a tube carrying parenteral fluid, whereby the tube may be manually constricted by pressing it against the platform adjacent the opening.

Abstract: In the process for preparing methyl tert.-alkyl ether comprising the steps of (a) contacting and reacting in the liquid phase a reaction mixture formed by combining a stream consisting essentially of C.sub.4 -C.sub.5 hydrocarbons and containing at least some proportion of isoalkylene and a stoichiometric excess of methanol, with respect to the isoalkylene, to form a reaction product comprising methyl tert.-alkyl ether, unreacted methanol and unreacted C.sub.4 -C.sub.5 hydrocarbons; (b) isolating the methyl tert.-alkyl ether from the reaction product; and (c) recovering the unreacted methanol from the residual portion of the reaction product; the improvement which comprises selectively adsorbing the methanol constituent of said residual reaction product in a bed of crystalline molecular sieve adsorbent and recovering same by desorption using as a purge-desorption stream, the C.sub.4 -C.sub.5 hydrocarbon stream used to prepare the initial reaction mixture.

Abstract: A refractory fiber composition and method for making refractory fiber from the composition. The refractory fiber composition includes kaolin clay as a source of alumina and silica to which is added zircon.

Abstract: The internal corrosion of metal mufflers used in conjunction with internal combustion engines is substantially retarded by maintaining in the external void space thereof an adsorbent mass of a combination of crystalline zeolites having the crystal structure of chabazite and the crystal structure of faujasite. These adsorbent compositions exhibit a synergistic effect on corrosion retardation. Novel muffler devices per se are also disclosed.

Abstract: A storm window latch mechanism which permits easy removal of a storm window sash when the latch mechanism is placed in one position and yet positively secures said storm window sash within the mounting framework when the latch mechanism is in a second position with freely slidable up and down movement being permitted. The latch mechanism includes a spring slider assembly having a low friction slide component mounted on the face thereof, with retention prongs provided on each of the respective ends of the spring member for engagement in appropriate apertures of the window sash, and a positive acting lever and bias spring structure connected to the middle portion of the resilient flexible spring member for actuation thereof. The lever portion is provided with two adjustment recesses which cooperate with a properly configured channel member mountable upon the edge channel of the window sash.

Abstract: Document feeding apparatus for feeding original documents of varying length to the copying station of a copier machine. If the document is less than or equal to a predetermined length, the document is moved to the copying station, a corresponding copy is made, and the original document is then transported to an exit stacker. If the original document exceeds the predetermined length, which length is slightly less than the length of a copy document, then the feed moves the original document to and through the copy station in increments slightly shorter than the length of the copy document, until the entire length of the original document has been copied. A particular use of the invention is in connection with the copying of adding machine tapes.
