Title: Indicating the relative degree positioning between and/or the frequency of mechanisms in a glassware forming machine
Inventor: FARKAS DANIEL STEPHEN
IPC: C03B11/16
Filed: 1982-12-09
Abstract: Pulse generators are connected to those forming mechanisms to be monitored. A clock pulse source generates three hundred and sixty clock pulses for each machine cycle and the pulse generators generate one reset pulse for every 360 DEG  of monitored forming means cycle. A switch means is provided for selecting the outputs of two of the pulse generators to be compared. The pulses generated by these selected generators are fed to a counter/display circuit having three inputs. A clock input receives the clock pulses generated by the clock pulse source. A clear input receives the reset pulse from the first selected generator. An enable input receives the reset pulse from the second selected generator. The counter/ display circuit counts the number of clock pulses received between the clear and enable pulses. The number of counted clock pulses represents the relative degree positioning between the selected forming mechanisms and can be displayed on a digital visual display. Alternatively, the counter/display circuit can receive pulses from a real time clock circuit and a selected forming operation generator to generate a display of operation per unit time, such as bottles per minute.

Patent GB-2131672-A (GB)
Title: Winnowing shredded tobacco
Inventor: BRACKMANN WARREN ARTHUR
IPC: A24B1/04
Filed: 1983-12-16
Abstract: Winnowing of shredded tobacco stem material, or other particulate tobacco material, is effected by metering the shredded stem material from a reservoir and then picking the metered flow to open and separate the particles one from another. The resulting stream of separated individual particles of shredded tobacco stem material is projected into an upwardly-flowing air stream to entrain a desired lighter fraction of the particles and carry it out of the separator device. The undesired heavy fraction falls in the separator device and is collected. The collected heavy fraction preferably is reprocessed to separate agglomerates of shredded stem material present in the heavy fraction into individual particles, which are then entrained in a second upwardly-flowing air stream which subsequently joins up with the first gas stream. <IMAGE>

Title: Dewaxing hydrocarbon oils using agitated indirect heat exchanger
Inventor: BROADHURST THOMAS EDWIN
IPC: C10G73/32
Filed: 1984-01-12
Abstract: Waxy hydrocarbon oil is dewaxed by mixing with cold dewaxing solvent to precipitate wax and thereby form a slurry of wax particles in an oil/solvent mixture at a temperature above the wax separation temperature. The slurry is passed into the entrance of an agitated indirect heat exchanger having chilled walls (3) and internal impellers (7) which are revolved at a speed sufficient to produce high agitation (corresponding to an impeller Reynolds number in the range of from 10<3> to 10<6>). The slurry is cooled below the wax separation temperature as it passes via the heat exchanger, and wax may readily be separated (e.g. by filter) from the wax/oil solvent slurry recovered from the exit of the heat exchanger to give increased yields of dewaxed oil/solvent. Chilled solvent B may be added to the slurry at separated regions of the heat exchanger. The slurry supplied to the entrance (6) of the heat exchanger may have been formed by passing the waxy oil into a direct heat exchange chilling zone having a plurality of successive stages and introducing respective amounts of cold dewaxing solvent into at least some of the stages while maintaining a high degree of agitation in at least a portion of said stages. <IMAGE>
