Patent CA-1124480-A (CA)
Inventor: BLACKMORE PHILLIP W
IPC: E04B2/56
Filed: 1980-04-11
Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE     An exterior insulation layer secured to an above-grade portion of a building basement is protected by a protective sheathing, preferably of impact resistant PVC or the like. The sheathing reaches about 6" - 12" below the ground so that the fill of the wall holds the lower end of the sheet in place.  The upper portion of the sheeting is directly or indirectly connected to the wall by nails or the like fasteners disposed at a location spaced inwardly of the plane of the exterior of the protective sheet.  The advance is in the extreme simplicity and the resulting low cost of the overall insulation of the wall.

Abstract: A B S T R A C T      To supply heat to the passenger compartment of an automo-bile car body immediately upon entering it, an approximately triangular housing has two branch outlet ducts converging from the opposite ends of a main inlet cross duct including a fan chamber containing a reversible electric fan.  This fan initial-ly draws cold air into the fan chamber of the main inlet cross duct and forces it through an electric heating coil and thence through one of the two converging branch outlet ducts to a com-mon outlet containing a freely pivoted damper which in response to the pressure of the forced air swings to cut off air flow from the other converging branch outlet duct and at the same time directs the heated air through a horizontal transverse duct into the passenger compartment.  When the compartment has been thus heated preliminarily, the operator de-energizes the electric heating coil and reverses the fan, causing it to dir-ect outside air through the conventional engine radiator-con-nected liquid heater of the automobile, and thence through the opposite converging branch outlet duct.  Thereupon the thus-forced air causes the damper to swing to an opposite position, closing the first converging branch outlet duct and  thenceforth supplying air heated by the conventional heater to the passen-ger compartment.  Electricity for the electric heating coil is provided by the car alternator and/or storage battery.

Abstract: ABSTRACT OF THE DISCLOSURE              Self Pumping Seal for a Reciprocating Member A self pumping seal for a reciprocating member provides cooling fluid to the reciprocating member with degradation of an elastomeric seal lessened by separating the elastomeric seal from the higher temperatures of the machinery.  Separation is provided by a relatively heat insensitive rigid seal which forms with the elastomeric seal a variable volume chamber.          A source of cooling fluid is in communication with the variable volume chamber so that as the volume of the chamber varies the cooling fluid will be pumped therethrough.

Abstract: METHOD OF AND APPARATUS FOR PRODUCING A           LOGARITHMIC REPRESENTATION OF AN INPUT VOLTAGE            Abstract of the Disclosure An input voltage is converted into a logarithmic representation thereof by exponentially changing the charge of a capacitor, producing pulses at a rate dependent upon the time taken for the charge to change between the two reference voltages, and counting the pulses during the time taken for the charge to change between the input voltage and a reference voltage, whereby the conversion is independent of the precise time constant govern-ing the exponential change.  The pulses can be produced under the control of a phase-locked loop, or by frequency-dividing clock pulses by a count which has been previously established by frequency-dividing the same clock pulse frequency by a predeter-mined factor. The conversion can be effected rapidly and accurately for input voltages within a relatively large range, without using high-precision components.          - i -

Abstract: Abstract of the Disclosure A node device for use in a digital data processing and communications system of the type utilizing a bus organization for facilitating the interconnection of a large plurality of digital data processing devices (user devices) in which redundant cables are employed.          The node devices are interposed between the user devices and the redundant cables to permit automatic reconfiguration of the interconnection of the user devices in the event of malfunctioning or severing of one or more of the cable sets within a minimum period of time. The node devices provide the user devices with the structure needed to detect and diagnose system problems and to effect recovery procedures. In accordance with the invention, one of the plurality of nodes functions as the Bus Controller and by sampling the remaining nodes in the system, it determines the priority with which user devices may transmit or receive data over the bus. Each of the nodes employed is substantially identical and any one may be selected to function as the Bus Controller. Each includes a Microprogrammed Controller and necessary firmware to permit the controller to function in conjunction with special purpose hardware including a Programmable Logic Array (PLA) configured to perform a pre-processing function on control line inputs so that poll/response traffic on the active cables can continue with a minimum of delay.

Abstract: ABSTRACT A directional drill attached to a drill string having periodic concentric collars is advanced in an inverted arcuate path to form a pilot hole underneath an obstacle followed by a larger concentric washover pipe. When the washover pipe reaches the surface on the other side of the obstacle a first reamer is attached to the end of the washover pipe exiting the drill-ing path, a second reamer of smaller diameter than the first reamer is attach-ed to the other end of the first reamer by means providing for some separ-ation between the two reamers, and a production casing of smaller diameter than the second reamer is attached to the other end of the second reamer with a swivel.  The remaining length of the first portion of casing is supported some distance above the ground on rollers located above and beyond the exit point of the pilot hole.  The reamers are operated by rotating the washover pipe and simultaneously drawing the washover pipe through the pilot hole.  As the reamers are drawn through the pilot hole the first reamer enlarges the hole to a diameter greater than that of the casing.  Drilling mud pumped through the washover pipe exits at the reamers to entrain the dislodged earth and the second reamer compacts it to form a bushing around the sides of the enlarged hole to lubricate the passage of the casing.  The reaming operation may be performed without the production casing attached to the reamers fol-lowed by a second reaming operation with the casing attached in order to com-plete the installation.

Granted: 1984-04-17
Abstract: ABSTRACT OF THE DISCLOSURE           Precise, point-by-point correction of spatial and shading errors in a camera television picture are performed manually.  The errors to be corrected are determined by visually examining a picture on a video monitor, by selecting an area for error correction which area corresponds to the type and extent of the specific error selected for correction.  A position command increments or decrements an address by preselected steps locate a movable "cursor" which, in turn, identifies the area being corrected.  A correction command retrieves the data from the area identi-fied, and which contains the error, selectively increments or decrements the data in preselected steps, and stores the new data back in memory.  The process continues until the operator is satisfied with the correction results.  Correc-tion thus may be made point-by-point, along horizontal or vertical lines or areas, in selected corner areas, etc., of the picture.
