Patent CA-1191233-A (CA)
Title: Flow regulating system
Inventor: PETRO DONALD P
IPC: F02D19/02

Abstract: ABSTRACT     This invention relates to the precision control of the rate of fluid flow in fluid conducting lines, and is particularly applicable to the control of gaseous fuel to an internal combustion engine.  The fluid is caused to flow through a plurality of parallel lines each of which contains a solenoid valve operated by digital signals from an electronic digital processor.  A plurality of sensors associated with the internal combustion engine monitor operating parameters, and provide signals to the electronic digital processor represen-tative of the parameters.  The relative flow rates of the lines are proportional to successive powers of two, and are determined by orifices in the lines which provide the above-noted relative flow rates in said lines at pressure differentials thereacross which are at or above that necessary to provide critical or choked flow in such orifices.  The electronic digital processor automatically programs the solenoid valves to provide the required total fuel flow rate for any particular set of operating conditions indicated by the signals from the sensors.

Abstract: ABSTRACT         An improved method for forming closed burstable pouches (10) having breakable seals.  The method includes selection of a laminated polymeric film (16) which has two principal layers -- an outer layer (20) which is responsive, and an inner layer (18) which is non-responsive, to a radio-frequency (RF) welding field, the outer layer (20) having greater cohesive strength than the remainder of the film and a higher melting point that the inner layer (18).  With two sheets of such material oriented with their inner surfaces in contact, the breakable seal (14) is formed by applying an RF welding field for a time and at an intensity to heat the outer layers (20) sufficiently to fuse the inner layers (18) by heat transfer from the outer layers without melting the outer layers.  In a preferred embodiment, two burstable pouches (10) are made from a double-sized intermediate pouch (26).

Granted: 1987-01-13
Abstract: Abstract of the Disclosure In a fractional distillation process in which it is desired to maintain a desired ASTM end point temperature of the overhead liquid product withdrawn from the fractional distillation process, changes in the heat removed by the fractional distillation process per unit of the feed are utilized to determine the equilibrium flash vaporization initial point and the equilibrium flash vaporization end point temperature for the overhead liquid product. The initial point temperature and end point temperature are then utilized to determine the actual slope of the equilibrium flash vaporization boiling point line. Changes in the slope of the equilibrium flash vaporization boiling point line are utilized to determine the actual slope of the ASTM boiling point curve at any particular time. The actual ASTM end point temperature for the overhead liquid product is derived based on the actual slope of the ASTM boiling point curve thus determined. The actual ASTM end point temperature is utilized to control the fractional distillation process so as to maintain a desired ASTM end point temperature for the overhead liquid product withdrawn from the fractional distillation process.

Abstract: TITLE SECRETARIAL ANSWERING SYSTEM WITH      DISTRIBUTED PROCESSING ABSTRACT OF THE DISCLOSURE A secretarial answering system for use with a switching system which includes a plurality of sub-scriber telephone stations each equipped with a buzzer, and a secretarial telephone station equipped with an audible signalling circuit and a plurality lamp and switch pairs.  A first processing unit periodically scans line circuits to determine changes in the busy, idle or ringing status of the subscriber stations.  A second processing unit converts status and line identi-fication information from parallel to serial format, and transmits it to the secretarial station via a link bus protocol for packetized messages.  The secretarial station then provides visual and audible indications of subscriber station status.  The secretarial station transmits switch initiated directed call pickup or a call transfer messages to the switching system, and a buzzing requested message to the second processing unit.  The directed call pickup message indentifies the subscriber station whose incoming call is to be trans-ferred to the secretarial station for screening.  The call transfer message identifies the subscriber station which is to receive a screened call.  The buzzing requested message is converted from serial to parallel format by the second processing unit and then sent to the first processing unit.  The first processing unit is thus informed to cause the called subscriber sta-tion's buzzer to provide an audible signal indicating that the current incoming call has been screened by a secretary.
