Patent CA-2024356-A1 (CA)
Title: Filter pulse-down cartridge cleaning mechanism
Inventor: MERRITT CHRISTOPHER R
IPC: B01D46/04
Filed: 1990-08-30
Abstract: ABSTRACT           A particulate material recovery system provides a flow of gas in which particulate material is entrained.  The particu-late material-laden gas is passed through a filter having an up-stream side and a downstream side, with the particulate material remaining on the upstream side while the gas flows to the down-stream side.  The downstream side exhausts through an opening into a plenum chamber wherein the gas pressure is less than the gas pressure on the upstream side and wherein means are provided for intermittently providing a cleaning gas flow in the reverse direction through the filter to remove particulate material from the upstream side.  A first valve controls gas flow through the opening.  The first valve operates in synchronism with the means for intermittently providing a cleaning gas flow substantially to stop flow through the filter from the upstream side to the down-stream side when the means for intermittently providing a cleaning gas flow provides such cleaning gas flow.

Title: Method and apparatus for measuring a phase-modulated signal
Inventor: KUECHEL MICHAEL
IPC: G01J9/02
Filed: 1991-05-01
Abstract: The invention relates to measuring a phase-modulated signal 5. The signal is measured along at least five different steps (P1 - P5) corresponding to preselected phase angles of the carrier wave 4. From the associated sets of measured values, at least three sets of measured values are used to determine at least three measured phase values for the modulated signal [.PHI.i = arctan (Z i/N i) where i is equal to or greater than 3]. The correct phase value is computed based upon the known frequency of the carrier wave. The essence of the invention is the finding that linear combinations of a i Z i and a i N i can be used for the computation of an accurate phase measurement where the factors a i are selected so that the phase error, as a function of the preselected phase steps, has at least three zero positions among the measured phase steps (P1 - P5). As a result, the systemic errors that normally accompany phase measuring are significantly reduced. The invention is particularly suitable for the evaluation of bar pattern images and multiple-bar pattern images.

Abstract: Abstract A single wire dryer group for a web-producing and particularly a papermaking-machine.  A plurality of heatable drying cylinders are arrayed in a row. A respective suction reversing roll is disposed between adjacent drying cylinders.  An endless support belt for the web to be dried travels alternately over a drying cylinder over the next adjacent reversing roll and then over the next adjacent drying cylinder.  Movable bearings support each of the reversing rolls so that the distance between the reversing roll and at least the preceding drying cylinder in the path of the belt is variable.  The direction of motion of the bearings is parallel to the central plane joining the axes of the two drying cylinders adjacent the respective reversing roll.

Abstract: ABSTRACT OF THE DISCLOSURE           There are disclosed a method and an implement for permitting one to precisely know the degree of the brilliance of a diamond, the colors of the light, and so on.  A gem to be observed or photographed is placed inside a container having an opening in the top.  The gem is so placed in the container that light can enter the container only from directions lying within the range of angles of 20 to 50 degrees about the line vertical to the gem.  The gem inside the container is observed or photographed from above the container while directing light into the container from above. As an example, the method is carried out with an implement comprising a container having an opening at the top, a reflecting plate having a hole in its center and disposed above the container such that the light reflected by this reflecting plate enters the container, and a seat portion on which a gem is placed.  The seat portion is located substantially in the center of the bottom of the container. The straight line connecting the seat portion with one fringe of the opening forms an angle of 20 to 50 degrees with the straight line connecting the seat portion with the opposite fringe of the opening.

Title: Process of making acceptable mozzarella without aging
Inventor: BARZ RICHARD L
IPC: A23C19/097
Filed: 1991-10-03
Abstract: In the manufacture of mozzarella cheese, aging can be dispensed with if the process is controlled to yield a combined moisture and wet milkfat content of at least about 70 weight percent, and the cheese will provide acceptable bake performance under typical cooking conditions used in the pizza industry today. Within about 48 hours after brining, the cheese should either be used or frozen. this discovery saves at least seven days of aging and permits the use of a continuous process of making mozzarella, which, from pasteurization to loading of the frozen product on the truck, can be performed in as little time as eight hours. In the continuous process, the hot stretched cheese from the kneading machine is extruded directly into cold brine. After the cheese has cooled sufficiently, it can be comminuted and frozen by independent quick freezing, preferably in a fluidized bed freezer. Salt preferably is mixed into the cheese during the kneading step.
