Abstract: A communication protocol available to any type module on the computer bus. Application programs are treated as clients or servers. A serveport is created in the server module. A client issues a connect request to the server identifying the serveport. The server assigns a N-slot TID capability to identify, describe and protect a storage location for receiving a start buffer from the client and sends the N-slot TID to the client to establish a connection. The start buffer includes a TID list which permits the client and server to reliably communicate back and forth. Once a connection has been established, data can be moved between the server and the client. High-level instructions and commands are sent as data through these connections. After the communication has been completed, the connection can be disconnected by the client or broken by the server.

Abstract: An improved memory system for use in a data processing system which memory system has two memory banks and corresponding error correction circuitry associated with each. Data words of a block thereof are stored in the memory banks in an interleaved fashion wherein alternating words are stored in one bank and intervening alternating words are stored in the other bank. During a write operation the memory is controlled so that the first data word of a block stored in a memory bank uses a late write technique and all subsequent data words thereof use an early write technique. During a read operation, pairs of data words are read and checked for errors simultaneously and are then supplied in a pipelined manner.

Abstract: A suction catheter provided with three conduits to provide th functions of suctioning, lavaging and oxygenating. The suction conduit is connected to a suction control member. The second conduit for the irrigating fluid is connected to a source of said fluid. The third conduit is connected to a source of gas under pressure. The gas conduit terminates within the irrigation conduit to form a common chamber at the distal end of the irrigation conduit from which fluid is propelled out by the pressurized gas. The gas may preferably contain oxygen.
Abstract: A vent cycle indicator for a suction catheter formed by a sleeve connected between a collar having a wiper seal and a crosspiece. The suction catheter includes a vacuum connection member having a normally closed valve. A catheter tube is connected to the vacuum connection member and extends through the collar and crosspiece. The crosspiece is for connection to a ventilator such that during ventilation the indicator sleeve expands and contracts during the inspiration and expiration cycles. The protective sleeve may be provided between the collar and the vacuum connection member to keep the catheter tube enclosed.
Abstract: A syringe tip cap and a method for purging air from a syringe-like container containing air and hazardous liquid. The cap contains a hydrophilic filter which, when dry, allows air to pass through the filter. When the air is purged from the syringe, liquid from the container is pushed or drawn to the filter. The filter expands when wetted, seals the cap, and prevents further fluid flow. A flow restrictor may be included within the cap to concentrate the flow to only a portion of the filter to prevent premature sealing of the filter.
Abstract: Monoclonal antibodies reactive with oncogenic and activated ras p21 proteins containing aspartic acid or valine at position 13 and unreactive with normal ras p21 proteins containing glycine at position 13. The antibodies are secreted by hybridomas obtained by immunizing mice with synthetic peptides corresponding in amino acid sequence to positions 5-19 or normal ras p21 proteins, except having aspartic acid or valine in place of glycine at position 13 and except for the addition of cysteine at the amino terminal end of the peptide. The antibodies and immunoreactive fragments are useful in the diagnosis, staging and classification of malignant and premalignant lesions.
Abstract: Recombinant fowlpox virus (FPV) capable of expressing immunogenic proteins of fowl pathogens are described. The FPV express DNA of the pathogen under the direction of FPV promoters. The recombinant FPV provide live vaccines for poultry and other animals.
Abstract: Monoclonal antibodies reactive with oncogenic and activated ras p21 proteins containing glutamic acid, arginine or valine at position 12 and unreactive with normal ras p21 proteins containing glycine at position 12. The antibodies are secreted by hybridomas obtained by immunizing mice with synthetic dodecapeptides corresponding in amino acid sequence to positions 5-16 of normal ras p21 proteins, except having glutamic acid, arginine or valine in place of glycine at position 12. The antibodies and Fab fragments thereof are useful for diagnosis, staging and classification of malignant and premalignant lesions.
Abstract: A blood containment device including a housing with an opening through which an adhesive ply of multi-ply material is exposed. Blood is expelled from a syringe onto the exposed material. The housing has two chambers, one for the clean material and one for containing a take-up reel onto which the bvlood stained material is wound. A removable tension plate is supported within the housing to hold the absorbent material taut beneath the opening in the housing.
Abstract: A communication link interface having an assembly register which is loaded in response to a transmitter's clock rate and unloaded in response to a receiver's clock connected to the interface. The assembly register holds a series of data words received from the communication link. Logic gates or flip flops are provided to insure a time delay between loading the assembly register and unloading it.

Abstract: A novel viral expression vector is employed in the expression of exogenous genes in "non-permissive" hosts. Exogenous genes under the control of a promoter which promotes expression in "non-permissive" hosts are thus used to expand the host range of the virus thus allowing production of polypeptides, including polypeptides which are toxic to the target host.

Abstract: An initialization or synchronization method in which at least a predetermined number of synchronization messages are sent out over a two-way communication line. The receipt of a synchronization message is awaited before terminating the transmission of synchronization message. After the transmission of synchronization messages has been terminated the receipt of a non-synchronization message will complete the synchronization process. However, certain conditions may cause synchronization to be restarted such as a predetermined number of consecutive error messages, failure to receive any message in a predetermined number of clock signals, receiving more than a predetermined number of synchronization signals, or a reset command.
Abstract: A computing system is disclosed which uses a system busy signal on its system bus to help control access to said bus. One or more requesters can generate a request signal when the system busy signal is not asserted. System busy is asserted along with the request signal(s) and remains asserted until all requesters which generated a request signal have gained access to the bus in order of priority. A freeze signal is generated on the system bus during the address phase of an instruction and a wait signal is generated during each data transfer in the data phase of an instruction. The freeze signal may be generated by a memory control unit, a memory module or a requester.

R.sup.2, and R.sup.3 can be H, or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, and R.sup.2 and R.sup.3 can be the same of different is disclosed. Kits that can be used to form these complexes are also disclosed.
