Abstract: A deburring tool with blades is described, for deburring both sides of the edges of boreholes, with at least one blade, consisting of a rectangular, edged cutting body with conically shaped cutting edges, with undercut ground open surfaces and with a contact surface on the front of the cutter head for contact with the interior of a borehole. The deburring tool produces bevels of a precisely defined size on the front and rear sides of boreholes. For this purpose a slide section is formed, departing from the angle of the cutting edge, which extends in the direction of the axial exterior part of the cutter blade and continues into a slide radius formed on the front of the cutting blade.

Title: Barrier wrapper
Inventor: HERD DOUGLAS M
IPC: E01F13/06
Filed: 1989-12-15
Granted: 1994-03-29
Abstract: ABSTRACT A wrapper for parking area gates or construction barriers is disclosed.  The unique wrapper consists of an elong-ate piece of flexible generally paper-like material of sufficient length and width to wrap around a barrier arm.  Indicia of diagonally spaced blocks of contrasting colours are affixed to the wrapper in a parallel manner.  When a barrier member is replaced, the covering is wrapped about the barrier member and secured to itself thereby producing instantly a new barrier for re-operation of the parking area or protection of the construc-tion site.  The invention eliminates the cost of expensive cuts of wood and meticulous painting each time the barrier is broken.

Abstract: TITLE               ROLLER RESILIENT BEARING     APPLICANT           SALVATORE ANTHONY DILORETO     INVENTOR        Salvatore Anthony DILORETO     ABSTRACT      A resilient roller bearing wheel or disk is constructed by forming a compound sleeve with an inner annular core and an outer resilient surround.  Preferably, they are molded from thermosetting plastic wherein the outer surround is a resilient material, for example, a resilient thermosetting plastic, while the inner annular core can be a resilient thermosetting plastic of less resiliency than that of the surround or, a firm or hard thermoplastic core.  In any event, the inner annular core defines a bore sized to accomodate a roller bearing of the prior art together with means for removably securing the roller bearing in the bore whereby, on excessive wearing of the resilient surround, the resilient surround may be removed from the roller bearing and a new one replaced thereon so as to achieve full lifetime use of the more expensive roller bearing.

Title: Quick-connect coupling
Inventor: STURGIS MALCOLM B
IPC: F16L37/40
Filed: 1992-09-01
Granted: 1996-07-30
Abstract: A quick-connect coupling for connecting a gas line to a gas appliance.  The coupling comprises a nipple and a socket member with a socket for  receiving the nipple.  A sleeve is slidable on the socket member from a retracted position in which the nipple may be inserted into the socket, to a locking position in which the nipple is held captive in the socket, and then back to the stated retracted position for disconnection of the nipple from the socket member.  Two valves are disposed in a flow passage in the socket member.  The first valve is biased toward a closed position and automatically opens upon insertion of the nipple into the socket.  The second valve is manually movable by means of a lever on the socket member from a fully open position for permitting maximum flow of fluid through the flow passage, through a range of movement in which  it is  only partially open to  a  fully closed position.  A detent member movable conjointly with the lever is engageable by the sleeve to prevent it from being moved to its retracted position when the second valve is fully or partially open.  The detent member is movable to a position for permitting the sleeve to be moved to its retracted position only when the second valve is in its fully closed position, thereby ensuring that flow through the second passage is completely cut off before the nipple and socket assembly can be connected or disconnected.

Abstract: An improved chemical treatment system (10) for hemo-dialysis machines, which in-cludes a first three way valve (26) which has a normally open position in the dialysis and rin-sing modes of the hemodialysis machine. The valve in the nor-mally open position couples a source of water (12) through the valve to the bicarbonate pump < 1 M G > (66) for rinsing purposes before and after dialysis and the chem-ical treatment modes of the he-modialysis machine. In the chemical treatment mode of the hemodiaiysis machine the valve is switched to couple a source (90) of treatment chemical through the valve to the bicarb-onate pump. The chemical treatment system includes a sec-ond valve (78), which if in the normally open .position, then only the bicarbonate portion and associated downstream portions will be chemically treated. In the closed position, the chemical will be switched to also flow through the whole hemodialysis machine from the water inlet to pro-vide for a half or total system chemical treatment cycle. A vent valve (98) coupled to the first valve can be included to further en-sure that chemicals are not inadvertently entered into the hemodialysis machine.

Granted: 2002-07-16
Abstract: An authorization mechanism for providing authorization information for a client requesting access to a server resource in a server, including a directory server for storing client information required by the server in executing an operation call, including client access rights, and a generating a request for an authorization ticket to the server. The request for an authorization ticket includes an identification of the client and an identification of the client information required by the server and is in association with an operation call. The authorization mechanism generates an authorization ticket including the identified information and encrypted with an encryption key derived from the password of the server. The authorization ticket is sent to the server and the server decrypts the authorization ticket with the server password and obtains the client information directly, including the client access rights. Client information is stored in directory server fields identified by generic field tags. The authorization ticket request identifies client information by tag names identifying the fields, the requested information in stored in the authorization ticket in fields identified by the tag names, and the server mechanism than reads the client information by parsing the ticket with the tag names.
