Abstract: ABSTRACT OF THE DISCLOSURE     A liquid dispensing device particularly suitable for automatically dispensing a lubricant to the combustion zones of an internal combustion engine.  A sealed lubricant reservoir conjoins with an air and liquid blending chamber formed by a housing.  The housing is sealed save for a minute air bleed aperture.  An inlet to the chamber for the liquid is provided in an upper part of the housing and an outlet from the chamber provided in a lower part of the housing.  The outlet is set up higher than a lower extremity of the chamber such that the outlet operates as a weir.  The outlet conjoins with a turbulating device comprised of an axially adjustable pin having an external helical groove.          The pin is mounted in a bore conjoining with a conduit to a required dispensing part, for example, in an inlet manifold of an engine.  Inlet manifold vacuum draws lubricant from the reservoir via the air with lubricant blending chamber and the turbulating device.

Title: Heat sensitive cable and method of making same
Inventor: DAVIS BAYARD C
IPC: G01K7/02
Filed: 1987-02-25
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE           A heat sensitive cable capable of generating a temperature representative measurable voltage.  The cable includes a pair of thermoelectric conductors disposed in contacting side-by-side relation together with an electrical insulation for passively self-generating a temperature rep-resentative measurable voltage between the conductors when the cable is exposed to ambient temperature.  A flexible outer jacket formed of an electrically non-conductive mater-ial is provided to completely surround the conductors.  The electrical insulation causes a change in the temperature representative measurable voltage with an increase or de-crease in temperature at every location along the jacket.  A change in the temperature representative measurable voltage under such condition is representative of a change in ambi-ent temperature.  The electrical insulation also causes a change in the temperature representative measurable voltage with an increase in temperature above the prevailing ambient at any location along the jacket.  With this arrangement, the heat sensitive cable may be utilized not only to monitor ambient temperature but also to monitor for any localized increase in temperature.

Title: Diagnostic and control system for cigarette filter rod making machine
Inventor: MILLEN WILLIAM L
IPC: A24D3/02
Filed: 1987-09-10
Granted: 1993-11-16
Abstract: ABSTRACT OF THE DISCLOSURE         A system for monitoring each of a multiplicity of variables in the operation of a filter rod making machine includes sensors located at various points on the machine. These sensors measure the value of such variable parameters as the width of the tow, the alignment of the wrapping paper, the speed of the rollers and the level of plasticizer   Each measured value is compared against preset limit values in a microprocessor.  If a variable is detected to be outside a range of acceptable values, an indication of this fact is displayed on a monitor.  In response to this indication, an operator can decide whether to override the limit value or take corrective action.  If corrective action is to be taken, the microprocessor causes a diagnostic chart to be displayed.  This chart provides the operator with a sequence of trouble shooting steps that can be taken to isolate the source of a possible problem and perhaps correct it before there is a need to arrest the operation of the machine.
