Abstract: A circuit for controlling data transfer hand­shake protocol so that certain protocol events may occur prior to or simultaneously with the completion of a proceeding protocol event, and the ultimate results of the pending protocol event may be determined at a later time. In one embodiment of the invention a CPU operates to transfer data (either receive or send) between itself and an I/O channel every five processor clock cycles. At the beginning of each set of five clock cycles the CPU places data on the data bus and generates a transfer request (CPU-XFR) signal whenever it receives a data accepted (DATA-ACC) signal indicating that a previous data transfer has occurred. The CPU-XFR signal is gen­erated regardless of whether or not the previous data transfer is complete at the time. The data transfer normally is completed one clock cycle after the CPU-XFR signal is generated, and at that time a transfer complete signal is generated. If the transfer complete signal is not generated, a transfer inhibits signal is gener­ated for inhibiting the generation of the succeeding DATA-ACC signal and hence the next CPU-XFR signal.

Abstract: An endotracheal or tracheostomy tube or catheter is described which is provided with a loose-fitting cover over the mouth of the tube and means to remove the cover once the tube has been correctly inserted into for example the trachea or nasal passage. The cover prevents mucus entering the mouth of the tube. Moreover when the tube is provided at the inserted end with an outer sleeve or balloon which may be inflated with air or liquid so that it acts as a gas seal and cushions the internal tissues of the patient, the cover also acts to protect the inflated balloon.

Abstract: A meter mounting assembly has a meter support plate (11) mounted on a base (10) via pillars 12. Flow-ways (20,25) extend upwardly from the base (10) and engage flow-­ways (29,30) extending downwardly from the support plate (11). One of the flow-ways from the plate (11) contains a stop-cock (35) in which the drive spindle (37) rotates, but does not move axially, and the valve spindle (40) moves axially but does not rotate. 
     A meter unit (54,55,57) in a casing (60) is supported on the support plate, meter unit (54,55,57) being clamped in the casing (60) by the action of a locking ring (62) which has apertures (65) for flow-ways. Between the stop-­cock (35) and the flow-ways (53) to the meter unit (54,55,57) is a turbulence reducing chamber (51). 
     The mounting of the meter unit (54,55,57) is designed so that it may be used, with differently configured components, for different meters. The resulting assembly is easy to dismantle for repairs.

Inventor: KOGGE PETER M
IPC: G06F11/14
Filed: 1989-06-08
Abstract: An improved checkpoint retry mechanism is disclosed which automatically updates checkpoint addresses to enable the retry of instruction sequences for shorter segments of recently executed code, in response to the detection of an error since the passage of the current checkpoint. It does this by updating three different types of checkpoint addresses, a first checkpoint address for the instruction which follows a memory write or I/O write operation, a second type checkpoint address for the first instruction in an interrupt service routine, and a third type checkpoint address for the first instruction in an interrupted routine following an interrupt event. The resulting checkpoint retry mechanism is more efficient and faster because it adaptively updates the checkpoint address to reduce the size of code segments which must be reexecuted during retry operations. The invention operates to avoid memory corruption and erroneous I/O outputs during retry operations and protects from erroneous retry sequences.

Abstract: A method for producing information is described which specifies the type of print head (18) present in a printer, which print head contains at least one printing element (86, 88, 90). The actuator of the printing element (86, 88, 90) has an electric resistance which is established via an evaluation circuit. This resistance is assigned to one of several resistance regions which correspond to different types of print head. The evaluation circuit produces as information a type signal (40a, 40b, 40c) dependent on the effected assignment. The type signal (40a, 40b, 40c) is made available to a downstream control which can supply different types of print heads (17, 18) with the fitting control signals in each case. The invention can be applied to virtually all types of print heads, the print elements of which are actuated via electrical or electromechanical actuators and which consequently have an electric resistance.

Abstract: An index rotary switch 10 is operated by a pushbutton 22 which, by a cam action of intermeshing teeth on the pushbutton 22, a housing portion 16 and a cam follower 24, causes solely rotary motion of a rotary contact carrier 28 journalled between a pair of thrust bearings. A rotary electrical contact 30 on the carrier 28 includes four resilient contacts for indexing with a stationary electrical contact array including three terminals 32,34,36 secured to a housing portion 18. In one position the rotary contacts are in the position X connecting terminals 32 and 36, whereas in the next position the rotary contacts are in the position O connecting terminals 34 and 36. The thrust bearings, namely an annular bearing in housing portion 16 and a spheroidal bearing 80 on housing portion 18, means that the rotary contacts press against the stationary contacts with a constant pressure even during operation of the pushbutton 22.

Abstract: A method and an apparatus for retrofitting and extending or upgrading an existing customer account servicing system to provide for automated handling and processing of both incoming and outgoing calls. A mainframe computer or host (16) contains customer or potential customer account records. A plurality of operator terminals (12) allow the operators to converse with the called or calling party and make changes to the customer account information via a data terminal (12a4). A system controller (11), trunk interface unit (10), operator terminals (12) and cross-point switch or PBX (13) provide a retrofit to an existing system, a mainframe computer (16), to provide for automated handling and processing of both incoming and outgoing calls. The system controller (11) and terminals (12) use the same command and data format structure as that already in use by the existing system and software or programs of mainframe (16). The system controller (11) is transparent to the operation of the mainframe (16) and the operator terminsla (12) and allows the system to be upgraded without the necessity of purchasing different software or programs for the mainframe (16). This invention is useful with both new and previously existing operator terminals (12). The system controller (11) monitors and handles both incoming and outgoing calls via the trunk interface units (10) and, when appropriate, causes the cross-point switch or PBX (13) to connect a selected trunk line (T) with an appropriate available operator terminal (12) and causes the customer account record to be displayed on the screen of the operator terminal.
