Abstract: Title SCROLL APPARATUS WITH ENHANCED LUBRICANT FLOW                         Inventors Robert E. Utter Daniel R. Crum Peter A. Kotlarek Abstract In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a means for enhancing lubricant flow through the scroll wraps. One or more passages are provided in one or both of the scroll end plates, each passage disposed to discharge lubricant between the scroll end plates, discharging adjacent the outer end of the scroll wraps immediately before the point where the scroll wraps form the first compression chamber to provide lubricant to the entire scroll wrap length.  Lubricant is provided to the passages by a combination of pickup tubes affixed to the scroll end plates and inlet openings in the scroll end plates.  The inlet openings accept lubricant discharged from the bearings in the apparatus.  The pickup tubes rotate with the scroll end plates and remove lubricant from a sump adjacent the scroll end plates.

Title: Toothbrush travel case
Inventor: SHAW JOHN D
IPC: A45D44/18
Filed: 1991-10-02
Granted: 1994-06-28
Abstract: ABSTRACT      A toothbrush case serving both as an original package case and as a permanent storage-travel case has female and male body members with thin resilient PVC plastic walls that overlap at a detented region for manual engagement and disengagement.  The case body members are in a preferred embodiment hollow receptacles defined by four quadrilateral walls and an end wall, with the male member funnelled for ready insertion into the female member.  Detent dimples in two opposing side walls provide a snap-lock position in a region where the two body members overlap so that they may be manually engaged and disengaged by means of the resili-ency characteristic of the walls. This resiliency absorbs impacts and shocks encountered in storage and assures long life without malfunctioning or breaking.

Title: Transparent remoting of switching network control over a standard interface link
Inventor: BALES BRUCE MERRILL
IPC: H04M3/22
Filed: 1991-10-17
Granted: 1996-07-30
Abstract: A switching architecture interconnecting remote switches to a central processor via standard links which may be set up through any number of intervening switching systems utilizing standard switching procedures. The standard links are ISDN links that may be set up dynamically via switching networks within the switching system or via the public switching network. The fact that an ISDN linkgoes through a portion of the switching system or the public switching network is transparent to both the central processor and remote switch. Upon detecting that a primary central processor is no longer in control, each remote switch attempts to obtain an alternate path to the primary central processor. If a remote switch isunable to obtain an alternate path to the primary central processor, the remote switch switches to an alternate central processor on the assumption that the primary central processor has failed. Because the paths can be made on directly connected ISDN links, through the switching system, or through the public switching network to either the primary central processor or the alternate central processor, there is a high probability of a remote switch being able to obtain such a path. To place calls switched by the remote switch under control of the central processor, the remoteswitch and the central processor each execute a plurality of hierarchical call control functions. Utilizing the ISDN protocol, these call control functions initiate and maintain a call through the switching system via the ISDN links. After initiating the call, the remote switch and the central processor establish a transport path on the call. Upon establishment of the transport path, low level call control functions in the remote switch transmit (via the transport path) all signaling and control information for other calls switched by the remote switch to high level call control functions in the central processor. However, the call that is communicating the transport path remains entirely under the control of the call control functions in the remote switch. The high level control functions in the central processor process the information and generate new signaling and control information. In order to control the other calls, this new information is transmitted to the low level call control functions in the remote switch via the transport path. Each ISDN link has a plurality of B channels and a D channel having a number of logical links. The transport path may be established on packetized B channels of the ISDN links communicating the call, on logical links of D channels of the ISDN links communicating the call, or by utilizing user communication facilities associated with the call.

Title: Improvements in or relating to subsea control systems and apparatus
Inventor: LOTH WILLIAM DENNIS
IPC: E21B33/035
Filed: 1991-03-28
Granted: 1997-06-03
Abstract: A subsea actuator for operating a valve (20) or the like comprises a movable wall member (19) fixed to an axially slidable     T stem and separating a pressure chamber (2) from a space (3) which is subjected to the hydrostatic pressure of ambient seawa-ter. A selector valve (11) is operable to connect the chamber (2) to a source of pressurized fluid, e.g. a source of pressurized gas (14), or to a drain e.g. connected to atmosphere by a pressure vessel (12) and pipe (15). A blowdown valve (16) and dump valve (13) are provided for ejecting liquid collected in the vessel (12). The space (3) may be connected to an open-bottomed container (17) to provide a gas barrier between the seawater and the interior of the actuator. Supply of pressurized gas to the chamber (2) causes the member (19) to be driven forwards, gas being allowed to flow past the member into the space (3) during this movement to assist the expulsion of water from the container (17) and the expulsion of any contaminants from within the actuator. When the chamber (2) is connected to atmospheric pressure the hydrostatic pressure of the seawater causes the member (19) to be driven in the reverse di-rection.

Title: Compounds and methods for the site-specific photoaffinity labelling of biomolecules
Inventor: BARNER RICHARD
IPC: C07C247/16
Filed: 1993-06-22
Granted: 2006-02-21
Abstract: The invention is concerned with novel heterotrifunctional compounds which contain a chemically reactive group R, a photo-chemically reactive group Ar-N3 and a reductively cleavable S-S(X2)-group. Novel heterotrifunctional compounds are of the general formula:   (see formula I) The chemically reactive group and the photo-chemically reactive group are separated by a spacer group which contains a disulphide group. The water-solubilizing groups are e.g. carboxylic acids and sulphonic acids or derivatives thereof which are attached either to the aromatic ring or to the spacer group between the aromatic ring and the cleavable SS group.        The compounds facilitate a novel photoaffinity method for the labelling of biomolecules, whereby the labelled biomolecule preserves its water solubility and the labelling molecule preferably projects free into the solution after anchorage to the surface of the biomolecule. The advantageous use of these compounds is illustrated of the basis of the functionalization of biomolecules by introducing an alkylthio function as a special embodiment of a photoaffinity labelling method.
