Title: Process control for liquid ventilation
Inventor: SHAFFER THOMAS H
IPC: A61M16/00
Filed: 1993-10-08
Abstract: A process is provided for controlling a ventilation procedure wherein a liquid ventilation system passes breathing liquid through at least a portion of a patient's pulmonary pathways. In this process, desired ranges for certain process parameters asso-ciated with the liquid ventilation system are established. These desired ranges are input into a central processing unit (50). Initial settings for the liquid ventilation system are then made such that the actual conditions which will initially occur during the liquid ventilation procedure fall within their respective desired ranges. Thereafter, the procedure is commenced. During the procedure, conditions are continually monitored by sensors (16, 21, 27). The CPU (50) compares the sensor readings with the desired ranges, and acts to correct any discrepancy. The CPU can trigger alarms (514).

Title: Driving method and drive for display device
Inventor: DENDA HAYATO
IPC: G09G3/288
Filed: 1995-11-17
Abstract: In an error variance processing unit to get a false half tone diffusing in the surroundings the luminance error between the original picture element signal quantizedly input and the preceding data,  one dot of said signal is converted into  plural  picture  elements.     The  respective  picture elements (pixels) thus converted are compared with the prior data  to  detect  the  luminance  error,  which  will  then  be weighted by multiplying it with certain coefficient to give, for instance,  the reproduced error in one line past, that in one dot past and further the reproduced error a in one-line and one-dot past,  which will respectively be added to the original pixels.   Producing a false tone by error variance in unit  of  pixel  enables  to  display  the  half  tone  without expanding  the  half  tone  display  area  beyond  required  dot number.

Patent CA-2171541-A1 (CA)
Title: Reinforcement strip
Inventor: LOOVERIE ALOIS
IPC: E04G23/02
Filed: 1995-07-14
Abstract: Grid-shaped reinforcement strip for reinforcing horizontal masonry joints. The strip comprises a number of reinforment steel wires (1, 2) running in the longitudinal direction, and a structure of one or more connecting wires (3) which are spot welded to the side edges of the reinforcement wires and have a round cross section with a diameter that is not more than the thickness of the reinforcement wires. The reinforcing wires are flat-rolled before the welding operation, so that the welds have an unflattened structure. The side edges of the reinforcement wires to which this spot-welding is done can be flattened by counter-rolling. Such reinforcement strips can be more easily manufactured in very thin embodiments, the use of which makes it possible to decrease the thickness of the masonry joint.

Patent CA-2172853-A1 (CA)
Inventor: THOMAS JULIAN PAUL
IPC: E01H5/06
Filed: 1996-03-28
Abstract: Our society is becoming increasingly aware of the importance and value of conserving our natural resources. However we continue to be a "throw away" society in many respects. The present use and disposition of hand snow shovels / snow pushers is one example of this kind of reality. After the leading edge of the blade wears out, the entire shovel is scrapped even though the handle and other accessories are still like new. In this invention, Eco Shovel, the life of this type of snow shovel would be extended indefinitely through a modification in the design of the original shovel blade combined with the application of a modified replaceable and protective wearable blade called Shovel-Saver (ref. Patent File No. 2,015,692-9, filed 1990-04-30, owner Thomas, Julian P., Appendix A). Both the shovel blade and protective wearblade would be of polyethylene construction. This combination of a modified snow shovel blade and modified protective wear blade would produce a modular and unique hand shovel - herein referred to as Eco Shovel. The use of this modular snow shovel would play a significant role in the conservation of natural resources; also it would save the consumer money by eliminating the need to continually buy and replace snow shovels due to normal wear.

Patent CA-2186960-A1 (CA)
Title: Thermoplastic threads continuous crimping process and device
Inventor: WEDER EUGEN
IPC: G01N33/36
Filed: 1996-01-30
Abstract: A texturing apparatus for producing a texturized thread according to a stuffer box crimping method comprises a conveyer duct 10 with an inlet opening for a trans-porting medium arranged at its upstream end and a stuffer box arranged down-stream adjacent to the conveyer duct 10 as well as a cooling drum T arranged downstream of the stuffer box and a thread tension measuring device FSS ar-ranged between the cooling drum T and a winding device SP.          The transporting medium M is conditioned to a predetermined pressure bymeans of a first control circuit with a first PI-control device and to a predetermined temperature by means of a second control circuit with a second PI-control device, i.e. conditioned to a state required for texturing. The plug formation is initiated by means of a stemming air flow S which is con-trolled by means of a third control circuit with a pressure control device DR. A pressure gauge 3 measures the compressing pressure in the conveyer duct 10 and transmits the corresponding signal to a comparator unit V which activates safety precautions, activating e.g. a light signal 4 or thread scissors 8. According to the example shown the idea of the present invention resides in the fact that a measurable parameter corresponding to the crimp quality of the thread is measured e.g. the thread tension being measured by means of a thread ten-sion measuring device FSS and that based on such measurements action is taken to e.g. vary the temperature of the transporting medium until the thread tension has reached a target value which is transmitted as a value WF to a thirdPI-control device which varies the target value PS of the first PI-control device until the thread tension has reached the target value WF.
