Title: Tubular heater for preparing carbon monoxide-containing gas mixtures
Inventor: HOHMANN FRIEDRICH
IPC: C01B3/38
Filed: 1994-08-02
Abstract: The tubular heater comprises numerous tubes, which are disposed in a combustion chamber and contain ca-talyst. A synthesis gas, which mainly comprises hydrogen, carbon monoxide, and carbon dioxide, is prepared in the tubes.

Patent CA-2140179-A1 (CA)
Inventor: SJOHOLM LARS I
IPC: F25B29/00
Filed: 1995-01-13
Abstract: A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compres-sor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respec-tively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchang-er. The valves are controlled in at least one predeter-mined open/close pattern during a null cycle, and prefera-bly in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which sub-stantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null tempera-ture range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein.      The system achieves the latter by controlling maximum operating pressure.

Title: Data connector for portable devices
Inventor: BOIE ROBERT A
IPC: H01R13/62
Filed: 1995-03-15
Abstract: Portable computing and communications devices are connected with other, typically fixed devices via the use of a capacitive data connector (FIG. 5). Each of the two mating sections (50, 60) of the connector includes a set of coupling plates (501, 502, 503, 601, 602, 603). When the two sections are brought into contact, the coupling plates form capacitors across which data signals can be passed Circuitry (100, 200) driving each section of the data connector is such as to create a bidirectional signaling path, thereby providing a connection which is functionally equivalent to an ohmic connection. Signals that are typically passed across dataconnectors on individual parallel leads are, in the present data connector, serialized, passed across the connector in that form and connected back to parallel form on the other side of the connection. Each section of the connector illustratively includes a permanent magnet (55, 65) to draw and hold the two sections in alignment, thereby providing a connector which is self-aligning.

Patent CA-2155395-A1 (CA)
Inventor: INABA MINORU
IPC: G03B21/64
Filed: 1995-08-03
Abstract: In cutting a film into individual screens and in fitting the screens onto the slide mounts, the positions for cutting the film are correctly set so that the film can be cut easily and quickly.  For this purpose, holes are perforated in an opposing manner in both side portions of the film in a direction in which it is fed.  The film is loaded into the camera, and a line L connecting the centers of the holes is brought into agreement with the center line of a gap portion between the screens.  The film is divided into individual screens when it is cut using a pair of scissors along the lines L that connect the holes of the film.  The ends of the holes in the direction of feed are semicircularly formed.  Therefore, if the film divided into individual screens is brought into engagement with the positioning pins of the slide mount, semicircular portions of the holes and the positioning pins are fitted to each other, and the film is correctly fitted onto the slide mount.

Title: Recombinant dna viral vector for transfecting animal cells
Inventor: SAITO IZUMU
IPC: C12N15/09
Filed: 1995-08-28
Abstract: An animal cell is co-transfected with both a recombinant DNA viral vector which bears a promoter, a recombinase gene and a poly(A) sequence and a recombinant DNA viral vector which bears two recombinase-recongnizing sequences and which further bears an origin of replication, a promoter, a foreign gene and a poly(A) sequence, each of which is located between the two recombinase-recongnizing sequences. Thereafter, in the co-transfected animal cell, a DNA fragment containing the origin of replication, promoter, foreign gene and poly(A) sequence is excised from the vector by the action of a recombinase expressed in the another vector.      The DNA fragment forms a circular DNA molecule which autonomously replicates in the co-transfected animal cell due to the origin of replication, whereby the foreign gene is continuously expressed.      Accordingly, the combination of the above two DNA viral vectors wherein a gene which is defective in patients is used as the foreign gene is quite useful especially for the treatment of the patient with hereditary diseases.

Title: Adaptive asynchronous media server request mechanism
Inventor: SCHMITZ PATRICK L
IPC: G06F13/14
Filed: 1994-04-13
Abstract: An asynchronous adaptive media server (16) mechanism permits a user to navigate around a modelled multimedia space as quickly as input events or instances are handled. The mechanism permits cancellation of outstanding queued requests that have become obsolete as the user navigates out of the area for which the request was needed. A client module (Fig. 8A) generates display requests by defining a client object for every active multimedia instance, and at least one server module (Fig. 8A) acts as a request queue manager and processes the requests. The server module (Fig. 8A) includes a media server (16) that preferably provides service of user-selected  quality. Upon request cancellation, client ressources can be released immediately; a server state module mechanism may release server resources until there is no risk of endangering system operations. The ability to cancel or deserialize  queued requests permits  prioritizing the requests in a fashion that will permit media server (16) performance to be adaptively optimized to match the user's actions. The disclosed mechanism has application to any media that does not have a time-linear  nature that maps directly onto some dimension of the modelled space displayed to the user.
