Title: Fireplace ventilation system
Inventor: BINZER LOTHAR
IPC: F24B1/187
Filed: 1995-03-02
Abstract: Apparatus for ventilating a fireplace having a combustion chamber within the interior of a building comprising an enclosure defining an air volume and a fan unit for generating a constant negative pressure region within the enclosure.  A venting passage communicates the enclosure with the combustion chamber of the fireplace such that the negative pressure within the enclosure draws combustion gases from the combustion chamber into the enclosure to ventilate the fireplace.  A valve is provided in the venting passage to control the flow of combustion gases to the enclosure.  With this arrangement, the fan unit is operated at a constant speed to generate a constant negative pressure within the enclosure.  There is no need to install an expensive variable speed fan to provide different levels of ventilation and, as long as the fan installed is sufficiently powerful to ventilate the enclosure, the valve can be used to adjust the ventilation of the fireplace combustion chamber via the enclosure.

Abstract: Methods are disclosed for providing operationial instructions to a hemodialysis circuit (10) hav-ing a dialysis filter (4g) and a capa-bility of operating according to a time-varying parameter such as var-iable ultrafiltration. According to the methods, entered are a desired time period, a target cumulative va-lue of the parameter, such as target ultrafiltration volume, and a pro-posed time-varying profile of the parameter that is representable as a plot of coordinates in a region de-fined by an ordinate of values of the parameter and a time-based ab-scissa defining a profile cumulative value of the parameter. If the pro-file cumulative value is not equal to the target cumulative value, then the proposed time-varying profile is changed along the ordinate to make the cumulative values equal.

Title: System for generating instructions for speech application
Inventor: HANES ROGER BRIAN
IPC: G06F9/44
Filed: 1994-07-01
Abstract: A system for generating instructions down-loadable onto an applications platform, such as a speech applications platform. Instructions are defined by a plurality  of parameter dependent operations, identified as blocks, which are linked together to specify an applications topology. Before parameters are entered, the validity of the skeleton of linked blocks is validated. Parameters are then added after a skeleton has passed a validity test. After parameters have been entered, so as to define the complete system, simulation is performed, including speech simulation. Simulation may be performed on a development platform or on a speech applications platform. A block may define a call to an external routine. The originally defined system is automatically converted into down-loadable instructions. The down-loadable instructions also include the call to the external routine, so that said routine may be called during on-line operation. Alternatively, stub blocks are included that allow C code to be embedded within down-loadable code.

Title: Bicmos current mode driver and receiver
Inventor: WONG BAN PAK
IPC: H03K19/013
Filed: 1994-04-28
Abstract: An apparatus for reducing transmisson delay tones when transmitting differential signals in an integrated circuit along long interconnect lines (10, 11) includes a current mode line driver which converts the differential signal to be transmitted into a signal that has a relatively low peak-to-peak voltage and large differential current changes. A receiver responsive to differential current changes converts the signal back into an output differential signal having peak-to-peak voltages adaptable to subsequent logic stages. A feedback circuit (Q5, Q6) coupled to the interconnect lines (10, 11) and the receiver functions to clamp the interconnect lines (10, 11) to a predetermined voltage while allowing the output differential signal to have peak-to-peak voltages greater than the predetermined voltage.
