Abstract: A slant plate type compressor having a  lubricating mechanism for a piston assembly includes a housing having a cylinder block pro-vided with a plurality of cylinders and a crank chamber adjacent the cylinder block.  A piston slides within each cylinder and is recipro-cated by a wobble plate driven by a cam rotor mounted on a drive shaft.  Each piston is connected to the outer periphery of the wobble plate by a  connecting  rod.  The piston has at least one piston ring disposed on its outer peripheral surface.  The piston and connecting rod are connected by a ball-socket connection. During the compres-sion stroke, the lubricating mechanism,  which has a conduit formed in the piston, supplies lubricating oil from the piston chamber and the pressure reduced refrigerant gas to a gap created within the ball-socket mechanism.

Patent CA-2038074-A1 (CA)
Inventor: ANDREWS ROLAND L
IPC: H04N7/18
Filed: 1991-03-12
Abstract: The scene-based image restoration system provides maximum local area contrast, to enhance the utility of video images generated from the input of a Forward Looking Infrared (FLIR) system.  While DC restored images display good ground/sky distinction for "Nap of the Earth" flying techniques, the use of scene data for image restoration is better suited for target detection against uniform backgrounds, e.g., the sky or sea.  Scene-based image restoration may be employed along with an alternative of DC restoration, thereby offering the pilot the option to choose the advantages of each method under various circumstances.         The video image is further improved by detecting faulty sensors and compensating for them in generating the video display.  By adjusting each of the working sensors to an optimum output relative to the other sensors, and eliminating defective sensors from the image generation process, an improved video image results.

Title: Pcl vertical graphics scaling using macros
Inventor: KOCHIS RICHARD L
IPC: B41J29/38
Filed: 1991-04-24
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a switch that allows a peripheral device, such as a PCL printer, to be shared by multiple computer systems.   The switch connects to each of the computer systems, and also to the peripheral device being shared. When the second of the two systems requests access to the peripheral device, the switch causes the peripheral device to save its state temporarily while the second system uses the device.  The second system prints graphics data on the printer, and scales the data as it is being printed.  In one, for each line being printed, the system saves the printer state, sends the line of graphics to the printer, scales and prints the graphics, and restores the printer state.  In another embodiment, all lines of graphics data are sent to the printer, then a command is sent to save the printer state, print all the lines, and restore the printer state.

Patent CA-2044429-A1 (CA)
Title: Method and apparatus for heat treatment of pulverous material
Inventor: JORGENSEN BJARNE M
IPC: F27B15/00
Filed: 1991-06-12
Abstract: By a method for heat treatment of pulverous material, e.g. burning of lime, the lime is first preheated by means of exit gas in a preheater (1, 2, 3) and subsequently burnt in a calci-ner (4, 14), after which the burnt lime is cooled in a cooler (6, 7).      In order to being able to alter the reactivity of the finish-burnt lime, the calciner is divided into two chambers, namely a first chamber (4) in which the lime is burnt at, e.g. 1050°C and a second chamber (14) in which a larger or smaller portion of the lime is further burnt at a higher temperature, e.g. 1300°C.      By means of a splitting gate (16) in the outlet from a separa-tion cyclone (5) for the calciner (4, 14), it is possible to determine the size of the portion of lime which should be ex-posed to the higher burning temperature in the second calciner chamber (14) and consequently to predetermine the reactivity of the finish-burnt lime.

Title: Anti-disaster monitoring system and anti-disaster monitoring method
Inventor: KIKUCHI MASAMICHI
IPC: G08B26/00
Filed: 1991-08-21
Abstract: Disclosed is an anti-disaster system for receiving terminal data in response to the sequential calling of the terminals which is achieved by designating addresses from a receiver and for performing alarming or the like. Each of the terminals has an interrupt transmission section for transmitting a break signal which invalidates a terminal response signal on a timing when the terminal response signal to the receiver is transmitted when an abnormality is detected to notify generation of an interrupt. The receiver includes an interrupt detection section for detecting an interrupt of a terminal when it receives the break signal at a timing when the terminal response signal is received, and a calling control section for specifying the terminal in which abnormality data is detected, the specification being achieved by transmitting the calling signals for interrupt confirmation to the terminals when an interrupt detection output is obtained from said interrupt signal detection section to allow the terminal to transmit the terminal response signal containing an interrupt level signal which indicates the cause of generation of the interrupt and by performing sequential group calling of the terminals on the basis of the order of priority of the interrupt level signal.      Consequently, when urgent data is detected at the terminal end, terminal data can be received quickly independently of the sequential calling and generation of an abnormality can be determined. Furthermore, since an interrupt confirmation request is made from the receiver to the terminal in response to the interrupt based on a break signal so as to allow the terminal to notify the cause of generation of the interrupt, an adequate processing, corresponding to the cause of generation of the interrupt, can be executed on the receiver end.
