Title: Cost metrics
Inventor: DENNIS STEPHEN V
IPC: B41J29/38
Filed: 1993-07-09
Abstract: A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A  system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. The inventive system sends a series of test instructions to the printer at the time the printers is installed on the host computer. A timer is used to time a predetermined period of time during which the draw primitives are sent to the printer for execution. Based on the number of draw primitives executed and the type of draw primitives executed, the system constructs a printer model. A log file is used to store the acquired cost metric data. In one embodiment of the invention, a clumping procedure is used to classify cost metric data. A series of cost tables stores the classified cost metric data. A map table provides a map to the cost table to speed up the process of cost metric data retrieval. At run time, a resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the host computer will render the band and transmit the bit-map of that band to the printer. If too many bands on one page are complex, the host computer may render the entire page and transmit the bit-map for all bands on the page.

Title: Actuator and zone valve
Inventor: GIORDANI ATTILIO G
IPC: F16K31/04
Filed: 1992-02-21
Abstract: A zone valve for a hydronic system (either heating or cooling) in which a motor-driven actuator (200) rotates a ball valve (130) through approximately 90·, between closed and opened positions.  The ball valve provides lower flow resistance than that of conventional heat-motor and motorized zone valves, allowing the use of lower rated pumps, and allowing a single size valve to serve most applications. A restoring torque is provided by a tension spring (346) so configured that it provides sufficient restoring torque to overcome the frictional torque of the ball valve (130). The restoring torque is kept from building up during rotation by configuring the spring in such a manner that its force varies inversely with the effective moment arm. The restoring torque varies by no more than 20 % (preferably no more than 10 %) during rotation of the ball valve. This assures that enough torque is always available to restore the valve to its closed (or open, in a normal open case) position, after the motor (200) is deenergized, but that there is not too much torque for the motor to overcome when it moves the valve (130) into the open position.

Abstract: Abstract of the Disclosure In a system for measuring moisture content of powder,  such as powdered milk while the powder is being dried, the powder is contained in a fluidized bed and a fiber optic probe is inserted through the wall of the container of said bed to be immersed in the fluidized bed. The fluidized bed continuously scrubs the outer surface of the probe window and prevents it from being coated with the powder.  Near infrared light is transmitted through a cable optic fiber and said probe to irradiate the powder in said fluidized bed and is reflected back from the powder into said probe and transmitted by said fiber optic cable to a spectroscopic analyzing instrument.   The fiber optic probe includes a sapphire rod having a back surface abutting the end of the fiber optic cable and an angled front surface.  The front of the probe is closed by a quartz window spaced from the angled front surface of the sapphire rod and held in position by an inwardly directed flange on the outer tubular casing of the fiber optic probe.  The front window is provided with an outwardly directed flange and an O-ring is sandwiched between the flange on the window and the inwardly directed flange on the distal end of the probe to provide a seal to prevent powder from getting in the probe.

Patent CA-2108709-A1 (CA)
Title: Suction systems
Inventor: DEVLIN THOMAS
IPC: A61M1/00
Filed: 1993-10-19
Abstract: ABSTRACT OF THE DISCLOSURE   Medico-surgical suction system are known in which the outlet of a container is connected to a vacuum pump, and an inlet is connected to a suction catheter. In the present invention the catheter is connected to the container inlet via a dual-lumen tube assembly one end of which is connected to the container and the other end of which has a suction control and a coupling for the catheter. A valve located in the outlet of the container is connected to the suction control via a minor lumen of the tube. A side lumen enables the vacuum pump to apply reduced pressure to one end of the valve, which holds the valve off against the action of a spring. Actuating the suction control allows air to flow to the valve via the minor lumen so that the effect of the reduced pressure is overcome and the spring opens the valve, thereby applying suction to the catheter.

IPC: B21D26/033
Filed: 1994-03-23
Abstract: A method of forming an elongated box shape tubular frame member from a round tube includes the steps of:  providing a lower die member having a cavity submerged substantially below the top surface of the lower die and having a cavity width equal to the width of the desired box shape frame member and less than the diameter of the tube.  The lower die has an entry opening which opens to the top surface of the die and is defined by angularly disposed funnel walls which converge to intersect with the cavity.  The round tubular blank is placed onto the lower die so that the blank rests on the angularly disposed funnel walls above the cavity.  The upper die is lowered onto the lower die and has a lid wall which forces the tubular blank downwardly into the cavity while the angularly disposed funnel walls guide the blank to collapse in a manner preventing pinching of the blank between the upper and lower dies.  The application of internal hydraulic pressure then expands the collapsed tube outwardly to the shape defined by the cavity of the lower die and the lid wall of the upper die.  The lower die preferably includes rounded corners at the intersection of side walls and a bottom wall to provide rounded corners on the box shape tubular frame member.  However, the edge surfaces of the lid wall of the upper die are rounded in the reverse direction away from the side walls of the lower cavity for ease of die manufacture, so that the rounded corners of the box shape tubular frame member are provided by controlling the magnitude of internal hydraulic pressure to a level sufficient to properly expand the tube against the side walls, the bottom wall, the lid wall, and the lower corners, while not so great as to force the upper corners fully into the reverse rounded upper corners of the die cavity.
