Abstract: MICROWAVE METHOD OF PERFORATING A POLYMER FILM            Abstract of Disclosure:         A method of forming perforations in polymer film includes the steps of forming a conductive film pattern on the film preferably in a bow tie shape using a material with a moderate resistivity and applying a microwave field across the film for a few seconds whereupon sufficient electrical energy is dissipated in the conductive spot to perforate the polymer.  This method is operative even when the polymer film is laminated between layers of other dielectric material prior to the microwave processing.

Abstract: Abstract This invention relates to erodable agglomerates containing  abrasive  grains  and  to  abrasive  products containing these agglomerates.        Conventional  coated abrasives typically consist of a single layer of abrasive grain adhered to a backing. It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece. It follows then that about 85% of the grains in the layer are wasted. Furthermore, the backing, one of the more  expensive  components  of  the  coated abrasive, must also be disposed of before the end of its useful life.        This  invention  provides  erodable  agglomerates containing  individual  abrasive  grains,  a  binder  and matrix material  selected  from the  group  consisting of pulp suitable for making paper and derivatives thereof, wood flour,  and vermiculite. The agglomerates are useful for  coated  abrasives  and bonded  abrasives.  Abrasive products containing the agglomerates provide higher stock removal than abrasive products bearing a single layer of abrasive  grains,  since  the  erodable  character  of  the agglomerates allows the sloughing off of spent individual abrasive  grains  during  abrading  operations  and  the exposing  of  new abrasive grains to the workpiece.  The invention  also  provides  a  method  of  preparing  the agglomerates of this invention.

Abstract: Abstract An  agricultural field sprayer is described,  having a  main boom  center  section rigidly mounted on a wheeled  motive  power source;  wing  sections of main boom hinged on either side of the center section are each supported on costarring wheels that can he locked  in  a non-castoring  mode  for  transport;  corresponding sections  of  spray boom and spray tubes with spray  nozzles  are mounted  on  the main boom sections to be rotated by rotation  of the spray boom.    Power from the motive source is used to rotate the boom.   The hinged wing sections can move between an  aligned working  position  along  the axis of the center  section  and  a transport  position,  trailing at right angles behind the  center section for transport.   In the working position,  the power also is used to adjust the spray tube height,  to accommodate variable spraying requirements.   The wing sections of the boom are partly drawn, in working position, by rigid boom draws which are latched and  unlatched  from  the  motive  power  source  by  appropriate movement of the spray boom.

Abstract: ABSTRACT OF THE DISCLOSURE    When  sensors are employed to monitor different operating variables  or parameters  in  a refrigeration system, the sensor outputs will normally have predetermined known relationships with respect  to each  other  as long as the sensors are functioning properly and regardless of the operating condition of the refri-geration system.   By comparing the output of one sensor relative to that of another sensor, a faulty condition of either of those two  sensors may  be detected.   For  example, during stabilized system operation the output of a condenser pressure sensor should always  indicate a higher pressure than that reflected by the output  of  an  evaporator  pressure  sensor.   By  effectively subtracting the evaporator pressure from the condenser pressure, a  faulty  sensor  may  be discovered.   If  the result  of  the subtraction  is zero or negative, at least one of the pressure sensors  is  defective.   When a  faulty  sensor  is detected,  a warning message is displayed to operating personnel.

Abstract: Abstract of the Disclosure Method and system for scrubbing exhaust gas stream from a wet process cement plant wherein a supply of alkaline water and a supply of compressed air are delivered to spray nozzles which are located within the existing exhaust stream ducting.  The alkali water is sprayed as a finely divided mist into the duct where it rapidly reacts with the oxides of sulfur and nitrogen present in the exhaust gas.  The water, being in the form of very small droplets, and having small volume and large surface area to water volume ratio, rapidly evaporates.  The water, therefore, does not cause a problem of wetting and clogging of the ducting and the oxides of sulfur and nitrogen are converted to dry solid particu-lates which are removed by normal dust collection systems down-stream of the scrubber.

With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.
