Title: Separable diamond shaped multidimensional filters for composite video endocing/decoding applications
Inventor: LEDINH CHON T
IPC: H04N9/78
Filed: 1990-04-27
Abstract: Various 2D and 3D diamond shaped filters for encoding  and decoding  NTSC,   PAL  and ATV  signals  are presented.    The particularity of the proposed system is its separability:  the desired filter configurations are composed  of   multiple   simple   ID   filters   operating individually in their own zero or oblique frequency axis.          In comparison  with existing diamond shaped filters the proposed  systems  offer  substantial  advantages,   low complexity  and  better performance  along the  zero  axes (horizontal,   vertical  and  temporal)  in  the  frequency domain.

Title: Process for immobilizing environmentally noxious metals and organic substances
Inventor: HOOYKAAS CAREL W J
IPC: B09B/
Filed: 1990-05-11
Abstract: A process of immobilizing environmentally noxious organic, particularly aromatic, substances by absorbing same on a layered clay mineral modified by exchange with a quaternary ammonium compound, thereby increasing the spacing between the layers and rendering the adsorption surfaces hydrophobic.     After  adsorption  of  the  organic  compounds  the spacing between the layers of the layered clay mineral is reduced  by  a  layer  spacing  reducing  agent,  and subsequently the clay mineral comprising  the organic compounds is mixed with a hardenable inorganic binder and the whole is hardened.     A  typical  example  of  a  modifying  agent  is  a quaternary ammonium compound,  and of a  layer spacing reducing agent an alkaline substance,  such  as sodium hydroxide.     Typical clay minerals are chosen among the smectite minerals, tectosilicates and phyllosilicates, preferably monthmorillonite clay is used.     The inorganic binder may be a calcium hydroxide compound or  a  calcium containing  cement,  preferably containing fly ash.

Title: Tree saver
Inventor: PETERS DALE T
IPC: B65B27/08
Filed: 1990-05-31
Abstract: ABSTRACT      In  business  boxes  are  used  for  the  purpose  of transporting various types and grades of paper to recycling facilities.  For the average person however there is no convenient method for the packaging and transporting of household refuse such as newspaper. In this invention the box is modified to allow for a convenient and efficient method of readying newspaper for the recycling depot. The box comes with string which is used to tie the bundles when the box has been filled. The string rests in a slotted base and is pulled up at the sides. At the top of each side a clip is provided to hold the string in place until the box is filled. The clips are made of cardboard with a wide opening which narrows. The string should become tight and secured as it is pulled down the narrowing portion of the clip. Once the string has been installed and secured the box can be filled with newspaper. When full the string is pulled out  of  the  clips  and tied,  thus  forming  a bundle  of newspapers ready to be transported to a recycling depot.

Abstract: An  electrochemical  sensor  electrode  is  formed  from  an electronic conductor (26) coated with a matrix (28) containing a perfluorosulfonic acid ionomer and a selected enzyme.  The selected enzyme catalyzes a reaction between a predetermined substance in a solution and oxygen to form an electrochemically active compound that is detected at the electronic conductor.   The resulting perfluorosulfonic acid polymer provides a stable matrix for the enzyme fox long lived enzyme activity, wherein only thin coatings are required  on  the  metal  conductor.     The  polymer  also advantageously repels interfering substances from contacting the enzyme and contains quantities of oxygen to maintain a sensing capability during conditions of oxygen depletion in the sample. In one particular embodiment, glucose oxidase is mixed with the perfluorosulfonic acid ionomer to form an electrode for glucose detection.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a process for the purification of 4-acetoxystyrene from a crude product mixture comprising 4-acetoxystyrene and typically 5 or more contaminants in substantial amount.  The crude product mixture is purified by melt crystallization by cooling the mixture to a temperature ranging from about +8°C to about -50°C, whereby at least a first portion of the mixture is crystallized; removing the liquid remaining from contact with the crystallized first portion of the mixture; and, subsequently slowly heating the  crystallized  first  portion,  while  simultaneously removing liquid which forms due to the heating, whereby impurities contained in the liquid which forms are removed from the crystallized first portion.         Surprisingly,  despite  the  large  number  of contaminants present,  and use of the process to purify crude product mixtures containing as little as 50% by weight 4-acetoxystyrene,  purities  as high  as 99.9% by weight   have   been   obtained   using   multiple   melt-crystallization steps of the process of the invention.
