Patent CA-1118088-A (CA)
Inventor: GLENN WILLIAM E
IPC: G10K11/20
Filed: 1978-06-12
Granted: 1982-02-09
Abstract: TO ALL WHOM IT MAY CONCERN:     Be it known that I, WILLIAM E. GLENN, citizen of the United States, residing in the State of Florida, have invented an  improvement in ULTRASOUND IMAGING SYSTEM     of which the following is a SPECIFICATION                   ABSTRACT OF THE DISCLOSURE           The disclosure is directed to an apparatus for scanning an object with a beam of ultrasound energy and for formulating image-representative signals from the ultrasound reflected from the object.  An ultrasound reflector is disposed in the path of the ultrasound energy, the reflector typically being disposed in a suitable fluid, for example water.  The reflector is mechanically driven and means are provided for sensing the relative angular position of the reflector and for generating a first clock signal as a function of the sensed position.  Means, responsive to the ultrasound reflected from the object are provided for generating echo-representative electrical signals.  These echo-representative electrical signals are stored at a line rate which depends upon the first clock signal.  Finally, means are provided for reading out the stored signals at a line rate which depends upon a second clock signal, and for displaying the read out signals to obtain an image of the object, the line  rate of the display being synchronized with the second clock rate.  In the preferred embodiment of the invention, the means for driving the reflector is adapted to drive the reflector at a non-linear rate, for example, sinusoidally.  This is advantageous in that the drive can be applied at a frequency which approximates a resonance of the reflector in the fluid, and the abrupt motions of a sawtooth drive are avoided.  In this embodiment, the duty cycle of the scan is enhanced by storing and displaying information obtained during both the positive and negative-going cycles of the sinusoidal drive.  In other words, informa-tion is obtained and displayed while scanning in both directions, so there is no wasted flyback period.  In the preferred embodiment, the electrical signals are stored in shift registers.  The information stored during an angular sweep of the scanner in one direction is read out on a "first-in-first-out" basis, whereas the information stored during the sweep of the scanner in the opposite direction is read out on a "last-in-first-out" basis.

Abstract: ABSTRACT OF THE DISCLOSURE     Surfactant-free emulsion coating compositions of superior film-forming properties are produced by a two-stage method comprising, in a first stage, forming a mixture of polymerizable monomers comprised of defined proportions of a carboxylic acid monomer, such as acrylic acid, and a C1-C8 alkyl acrylate or methacrylate, polymerizing said mixture, neutralizing the polymer product with a sufficient amount of an amine or base to make it water-dispersible and forming an emulsion of the polymer with water, then, in a second stage, forming a mixture of polymerizable monomers comprised of defined proportions of a C1-C8 alkyl acrylate or methacry-late and adding this monomer mixture and a polymerization catalyst to the emulsion produced in said first stage and heating the mixture thus formed to effect polymerization and produce the emulsion coating composition.  The method produces an emulsion comprised of polymers of higher molecu-lar weight than producible by conventional emulsion coating forming means and without the use of a surfactant as done conventionally.

Abstract: Abstract of the Disclosure Condensing head pressure in a refrigeration system having its condenser exposed to low outside ambient tempera-tures is controlled to provide the minimum head pressure required for a given mode of operation.  A hierarchy of operating modes, each with its associated pressure is esta-blished, including normal refrigeration, evaporator defrost and heat reclaim.  The control system prevents system head pressure from going below the minimum required for the operating mode in effect at a given time, with modes requiring higher pressure overridding lower pressure modes when required.           In heat reclaim operation, high pressure gas from the compres-sor is diverted through a heat reclaim coil, and a subcooling sensor or other sensing means controls system head pressure to the minimum pressure that will maintain full condensing in the heat reclaim coil, which is the most economical mode of operation.  In a multiple system, head pressure of the various systems are brought up sequentially to the pressure for full condensing in their heat reclaim coils so that if additional heat is needed the next stage is brought in, rather than further increasing the pressure of the previous stages.    This has been found to be more economically efficient than providing further increases in head pressure above the optimum point of just fully condensing all vapor entering the reclaim coil to liquid.

Abstract: ABSTRACT         An apparatus for smoothing transmission errors in a receiver in order to compensate for digital errors occuring in a transmitted signal.  The apparatus includes a device to generate an output signal, which corresponds to the signal transmitted by the transmitter with a high degree of probability.  The device includes a device in which a predetermined number of bits are detected and an evaluation is made whether each received bit ex-ceeds or falls below a predetermined threshold value.  For each bit or group of bits which is detected and falls below said threshold value, the redundancy of bits in the signal is used to determine the correct value of the detected low value bit.          From this, a bit signal is generated which more closely corres-ponds to the value of the bit transmitted by the transmitter than to the received value.

Abstract: A unified tile scoring and fracturing device having a simple adjustment for making straight or diagonal cuts on a piece of tile. The tile cutter provides a guide rod above and parallel to the base of the tile cutter and a single control handle having widely disposed lateral fins. A rota?ble tile scoring wheel is provided at the forward base of the con-trol handle to score the tile. The handle is movably and slidably fitted along the guide rod. Tile cutting is effected by sliding the handle along the guide rod while exerting downward pressure to cause the scoring disk to score the tile, thereby making a cut line. After the tile is scored, further downward pressure is exerted on the handle to cause the lateral fins to fracture the tile along the scored line. A simple novel means is provided to position the tile on the tile cutter accurately for both straight and diagonal cuts.

Abstract: C-17-21-3203 ELECTROSTATICALLY AUGMENTED FIBER BED SEPARATOR ABSTRACT A method and apparatus for removal of particulates from gas streams with high collection efficiency on even submicron particulates. The apparatus includes a grounded fiber bed of 50 to 1000 micron average diameter fibers packed to a bed voidage of at least 90%, an electro-static or ionizing field means upstream of the fiber bed to place an electrical charge on the particulates, and irrigation means for the fiber bed, and optionally the grounded electrodes of the electrostatic means as well, to flush collected particulates from the fiber bed and optionally from the grounded electrodes. The method is suitable for separation of any particulates but is particu-larly advantageous for separation of insoluble solid particulates from gas streams at high bed velocities of from 6 to 15 or more feet per second (i.e., 1.8 to 4.6 or more meters per second). The preferred fiber bed is of 100 to 500 micron diameter, and advantageously 100 to 250 micron diameter, glass fibers. In operation, particulates are charged in the electrostatic means and the charged particulates are collected in the fiber bed where the elec-trical charge is dissipated through the irrigating liquid/particulates mixture so that no significant space charge effect is allowed to develop in the fibers of the fiber bed and re-entrainment of particulates is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE      A rotary vibration damper comprises one or more vanes secured to a rotor within a housing filled with damper fluid, the vane or vanes cooperating with one or more fixed walls to define complementary fluid-filled chambers within the housing between which fluid will flow as relative vibratory movement occurs between the housing and the vane or vanes.  A partition wall movable axially within the housing like a piston is spaced from one end of the vane or vanes to define a restricted path for the flow of damper fluid between complementary chambers.  The restric-tion of the flow path, and hence the vibration damping effect, can be increased or decreased by axial movement of the partition wall.

Abstract: ABSTRACT         There is provided an animal trap which is specific to a given range of animal weights.  The trap has a frame, and a spring-arm pivotally mounted at one end to the frame and having at the other end means for entrain-ing a cable.  The spring-arm can swing from a horizontal position to an upwardly extending position, and is spring-biased toward the latter.  A trip lever can move between two positions, in one of which it retains the spring-arm in the horizontal position, and in the other of which it releases the spring-arm.  An animal stepping on the trip lever can cause it to release the spring-arm.          The cable is anchored at one end and has at the other end a loop adapted to be placed so as to surround the trip lever.         Means are provided for avoiding the springing of the trap by an animal lighter than the given range of animal weights for which the trap is specific, this means including a spring urging the trip lever toward the position in which it retains the spring-arm horizon-tally.  Further means are provided for avoiding retention in the trap of an animal heavier than the given range, and this includes a connector in the cable which joins one portion of the cable to another portion, such that the connector is capable of releasing these portions from connection together upon the application of a sufficient force.  This will allow a heavier animal to break free of the trap.
