Patent CA-1292704-C (CA)
Inventor: CAMPBELL DOUGLAS C
IPC: F16L55/28
Filed: 1987-04-07
Granted: 1991-12-03
Abstract: ABSTRACT          The pipeline packer described herein typically includes a main body adapted for propulsion through the pipeline in an axial direction.  A brake shoe support assembly is located on the main body and a plurality of circumferentially spaced brake shoes capable of gripping the interior wall of the pipeline are mounted to the support assembly.  Fluid pressure activated means are associated with the bake shoe support assembly for urging the brake shoes radially outwardly into griping engagement with the pipeline to secure the main body in a desired location in the pipeline against the pipeline pressure forces acting thereon.  A pair of annular wedging means are also mounted to the main body for axial movement toward each other as the fluid pressure activated means acts on the brake shoe support assembly to urge the brake shoes into gripping engagement.  An annular sealing member of elastomeric material is located between the annular wedging means and is adapted to co-operate with same so as to expand radially outwardly as the annular wedging members move toward each other.  The packer also includes fluid pressure supply and control means connected to the fluid pressure activated means so that on demand the brake shoes urged into gripping relationship with the pipeline while at the same time the annular sealing member is expanded into sealing engagement with the pipeline wall.

Title: Twist cap having adjustable flow rate
Inventor: STULL GENE
IPC: B65D47/24
Filed: 1987-10-13
Granted: 1990-10-23
Abstract: TWIST CAP HAVING ADJUSTABLE FLOW RATE                       ABSTRACT    A dispensing cap construction including a base cap attachable to a container, the base cap having a spout formation provided with a side wall and with a flow pas-sage in the side wall, and a cover cap which is both turnably mounted on the base cap and axially movable thereon between a lowered sealing position and a raised dispensing position. The cover cap has a discharge ori-fice, and a valving wall and discharge passage in the valving wall, both of which move circumferentially around the side wall of the spout formation. The valving wall moves into and out of a sealing position wherein it cov-ers or uncovers the flow passage in the side wall of the base cap when the cover cap is turned. The valving wall has positions intermediate its full cover and full uncov-er positions wherein it only partially closes the flow passage. The discharge orifice of the cover cap is sealed at a point downstream of the flow passage of the base cap when the cover cap is in its lowered position there-on. The advantage of the present invention over the de vices of the prior art is that a more precise control of the flow rate can be achieved, resulting in less product waste and easier operation by the consumer.
Patent CA-1281857-C (CA)
Title: Vacuum cleaner with improved auxiliary cleaning
Inventor: STEADINGS STEPHEN W
IPC: A47L5/32
Filed: 1987-11-13
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE A vacuum cleaner main cleaning chassis has a pair of suction air channels leading from a principal suction area thereof.  Suction force is provided in common in the air channels with a single suction motor. One of the suction air channels is adapted to receive an auxiliary cleaning hose which diverts the suction force in such air channel into the auxiliary hose. During such auxiliary cleaning, increased suction force may be created in the auxiliary hose by closing off air flow in the other suction air channel, which relieves part of the load on the common suction motor.  Such relief results in increased notational speed of the motor, which in turn correspondingly increases the suction air flow in the air channel associated with the auxiliary hose.  In an upright vacuum cleaner, such close-off is accomplished by pivoting the handle and dirt bag carried thereon into an upright position so that a relatively rigid portion of the bag engages against an extended exhaust port corresponding with the suction air channel in which air flow is to be interrupted.  The exhaust port corresponding with the air channel in which the auxiliary hose is interposed is not similarly extended, so that auxiliary suction air flow continues unimpeded even when the control handle and bag carried thereon are pivoted into an upright position.  The resulting boost in suction air force in the auxiliary hose provides for improved auxiliary cleaning performance.

Inventor: SALETTA GARY F
IPC: G01R19/25
Filed: 1988-02-17
Granted: 1992-08-04
Abstract: 71                  53,666 ABSTRACT OF THE DISCLOSURE A motor controller system is taught in which an overload  relay  board  utilizes  a  current  monitor  which produces an output signal which is related to the current being sensed thereby over a wide range of currents which may vary for instance between 1 and 1,000 amperes.  This indicative signal is converted to a DC voltage level which is then provided to the  analog-to-digital portion of  a microprocessor for being converted to a digital number for being processed  by  the  microprocessor  for  causing  the contacts of the motor controller to open at appropriate current values.  The system utilizes an integrating capaci-tor which samples the output current from the sensor 32 times in succession providing a voltage which is propor-tional to the line current.  This voltage which may exceed the input voltage level of the analog-to-digital converter is nevertheless supplied to the analog-to-digital converter and sampled internally by the microprocessor at double the line cycle time period until the 32 samplings have expired. If at any time during this doubled sampling process the output of the analog-to-digital converter digitally satu-rates, the left shifting technique is provided with other memory locations within the microprocessor to provide an approximate double value of voltage so that at the end of the 32 line half cycles a very close approximation of the actual current is contained within storage locations within the microprocessor for effective utilization thereby.

Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus are described for the reproducible representation of a surgical procedure. The position or path of movement of the surgical instrument during the operation on concealed parts of the body is represented in order to document the course and results of a surgical procedure and then stored for subsequent examination. This is achieved in that a stratified image that has at least threemeasurement points on the patient is stored in a computer and reproduced on a display. In addition, the position of the three measurement points and the position of the surgical instrument can be determined before and during the procedure through a coordinate-measurement system, superimposed with the stratified image on the display, and stored in a memory unit. The method and the apparatus (coordinate-measurement system) are well-suited for reproducing and documenting surgical procedures.

Abstract: METHOD AND APPARATUS FOR COMMUNICATION NETWORK           ALERT RECORD IDENTIFICATION                           Abstract Alert records flowing in a communication and data processing network to host operator console stations consist of long, variable length information records.  Method and apparatus are disclosed which reduce the variable length body of information to a standard 32-bit number which indexes the lengthy, variable length information.  To the 32-bit number there is concatenated a product identification code which reduces the likelihood of inadvertent duplication of the 32-bit number by two different alert sending entities to an acceptable level.  The IEEE standard 802 cyclic redundancy check algorithm, ordinarily employed for checking the integrity of data transmission in a communications system, is employed in a new way to reduce a long, variable length body of alert data information to the 32-bit number.  Reduction of the alert record to a 32-bit number plus the product identification code enables alert recognition and filtering to be conducted at the host/system network operator's console for logging, displaying the alert to speci-fied operators, selective display, inhibition of these or forwarding of the alert to an additional operator or use of the alert as a triggering signal for the display of specific informational screens for the opera-tor.  Useless alerts in a particular environment may be discarded altogether and recognized prior to displaying them to the operator.
