Abstract: ABSTRACT OF THE DISCLOSURE     Improved waterproofing membranes of the pressure-sensitive or self-adhesive bituminous type particularly useful in roofing and for waterproofing substrates in general are described. The membranes are in the form of pre-formed, flexible, sheet-like laminates of (a) a layer of waterproofing pressure-sensitive bituminous adhesive such as a rubberized asphalt composition, and, (b) a flexible support sheet having an adhesive-promoting coating on one or both surfaces to improve its bonding to the bituminous adhesive to which it is laminated and/or to the bituminous adhesive layer of a like overlapping waterproofing membrane.  The adhesion-promoting coating contains a polymer having a plurality of pendant carboxylate groups from its backbone (e.g. an acrylic polymer such as polymethylmethacrylate, or a polymer of a vinyl ester such as polyvinylacetate).  Adhesion between such coating and the bituminous adhesive is promoted by subjecting the contacting portions to elevated temperature.  The membrane is preferably provided further with a layer of removable protective material such as siliconized "release" paper placed adjacent the adhesive layer in order that the membrane is able to be transported to the job site.

Abstract: Ultrasonic Imaging System Using Digital Control Abstract A real-time ultrasonic imaging system is disclosed which includes an array of transducers adapted for propa-gating ultrasonic energy into a body to be ultrasonically examined and for receiving reradiated energy from points within the body.  A plurality of signal channels each includes a transmitter branch and a receiver branch associated with respective transmit and receive trans-ducers, or both branches may share a single transducer. A transmitter branch activates a transducer to propagate the sonic energy and a receiver branch receives from the transducer electrical signals corresponding to the reradiated energy.  Memory means in each receiver branch receive and store data indicative of the signal level passed to the channel by its associated transducer. Display means are provided for receiving the data from the memory means in each of the channels and for com-bining and processing such data to effect a real-time display of the bodily portion being examined.  Timing generator means in each of channels, connected to the transmitter and memory means associated with that channel, activate the respective transducers at pre-determined times to phase the transducers to enable steering and focusing of the array.  The timing generator means also function to gate data into the memory and at a later time to gate out the data from the memory (at predetermined intervals), thereby controlling the bodily points from which the re-radiated sonic energy is received and to enable steer-ing and focusing of the transducer array during the receiving operation of such array.  Control logic means are connected to the timing generator means for enabling the former to provide signals to the memory means and transmitters in each of the said channels.

Title: Automatic changeover system for liquid dispensing  system
Inventor: CREDLE WILLIAM S JR
IPC: B67D7/36
Filed: 1980-08-05
Granted: 1982-10-05
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention is directed to an automatic change-over system for stock rotation of liquids packages in plural collapsible bag-type reservoirs including an improved automatic change-over valve.  The bag-type reservoirs are divided into primary and secondary groups, the primary group containing a supply of liquid product which is currently being dispensed and the secondary group containing a supply of liquid product which is held in reserve.  An automatic change-over between the primary and secondary groups of bag-type reservoirs is effected in response to a vacuum created by an empty condition in the bags in the primary group.  A pressure change in the system results from the deflation of the empty bag-type packages which switches the change-over valve.  Thus, the change-over is caused by the characteristics of the flexible bags containing the liquid being dispensed and the valve mechanism which connects the primary group, the secondary group and a dispensing pump together.

Abstract: Abstract of the Disclosure A D.C. gaseous discharge display panel operated in a storage mode uses a layer of resistive material over the cathodes of the display.  In addition to protecting the electrodes from ion bombardment induced sputtering during discharge, the material provides a resistance to each discharge cell, provides isolation between individual cathodes by reducing discharge spreading along the cathode conductors and prevents surface charge building during panel operation.  By utilizing a combination of metal and insulator in the resistance layer, the D.C. discharge can be sustained at lower operating voltage, permitting a reduction in the power requirements of the panel.

Abstract: ABSTRACT OF THE DISCLOSURE         This specification generally discloses electro-chemical cell for use in a gas detector unit, and more particularly,  a cell for sensing reducible gases including, for example, NO2, Cl2, O3, ClO2 and O2.  This is achieved by the use of gold as the sensing electrode in combination with a material selected from the group of iridium and ruthenium as the counterelectrode, and preferably iridium.  For three electrode sensors wherein a reference electrode is utilized, preferably the material will be selected which is similar to the counterelectrode material.  However, the material may be selected from platinum, iridium and ruthenium.  The effect of this combination of materials utilized in the electrodes of the sensor of the invention is a more stable continuously operating cell, not subject to the usual degradation of prior art cells.  Thus there is disclosed an electrochemical sensor for the detection of electrochemically reducible gases comprising (a) an electrolyte; (b) a sensing electrode in contact with said electrolyte; and (c) a counterelectrode in contact with said electrolyte.  Said sensing electrode is comprised of gold on a porous hydrophobic membrane; and said counterelectrode  is a member selected from the group consist-ing of iridium and ruthenium.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention suppresses dust, and particularly respirable dust, by preventing the dust from becoming airborne at locations where it could escape from the dusty material with which it is associated, for example, at transfer points and other locations where the respirable dust can be released into the surrounding atmosphere.  Foam, having bubbles small enough to be broken by respirable dust particles, is brought in con-tact with the respirable dust where small bubbles, small enough to be bursted by respirable dust particles, are imploded and the bubbles wet the dust particles and cause adherence of the particles to adjacent surfaces, such as other foam or other parts of the dusty material.  The foam may be discharged into dusty material at transfer points where the dusty material falls by gravity and thereby opens up spaces between portions of the material which are at zero gravity as a result of their free fall.
