Abstract: DEVICE FABRICATION METHOD USING SPIN-ON GLASS       RESINS AND DEVICES FORMED THEREBY                            ABSTRACT A new method for fabricating a device, such as a semiconductor device, is disclosed.  The method includes the step of patterning a substrate (e.g. 10) with a trilevel resist (e.g. 30) containing a spin-deposited substitute (e.g. 50) for the conventional central, silicon dioxide region.  This substitute includes an organosilicon glass resin in combination with metal-and-oxygen containing material.  The inventive method prevents the losses of linewidth control, and avoids the pattern degradation due to undesirably many pinholes, of previous such methods.

Title: Deflector for hatchbacks and the like
Inventor: MARTENS PETER
IPC: B60J1/20
Filed: 1987-01-13
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE      Hatchback and station wagon rear windows often suffer from dust, snow and rain deposition when driven in adverse weather conditions and perforated or solid air deflectors are normally secured across the rear of the roof of such vehicles in an attempt to deflect air over the rear window in order to keep same relatively clean.          Sometime  rear window wipers are employed.   The attach-ment  of  such  deflectors  in  the  correct  location  for efficient operation is often difficult particularly with hatchbacks inasmuch as it must be relatively close to the upper transverse edge of the hatchback panel in order to be efficient but this often interferes with the closing of the hatchback panel.  The present device is a deflec-tor which attaches to the upper rear window frame rather than on the roof so that the correct location is possible for maximum efficiency yet the deflector lifts with the hatchback door or upper window portion of a station wagon tail gate without interfering with the rear side of the roof panel.

Abstract: ABSTRACT OF THE DISCLOSURE           A package for use in a microwave oven is sealed at both of its ends.  The package is transversely folded intermediate its ends to form a first compartment in which one food product is contained, such as kernels of corn to be popped, and a second compartment in which is contained a second food product, such as a flavoring component or additive.  The fold in one face wall extends inwardly and the fold in the other face wall extends outwardly, the two folds being nested together.  The sides of the package are pleated.  Whereas the transverse sections forming the folds are secured together in one instance and secured to the other in another instance, the pleats of the other face wall are secured to the fold in the one face wall by adhesive spots.  A sufficient build-up of pressure in the compartment containing the kernels to be popped will cause the folded configuration to at least partially unfold, thereby providing communication between the compartment in which the kernels are contained and the compartment in which the flavoring component or additive is contained.  The configuration of the fold is such that a dam remains which prevents any undesired flow of additive from the compartment in which it is contained into the compartment in which the corn kernels are initially contained.  By grasping the closed end adjacent the second compartment and allowing the package to assume a vertical condition, the user can shake the package, simply moving the closed end up and down so that the additive in the second compartment gravitationally flows downwardly into the first compartment where it is dispersed throughout the popped product.

Title: Biological purification of waste waters
Inventor: VON NORDENSKJOLD REINHART
IPC: C02F3/00
Filed: 1988-07-29
Granted: 1994-08-09
Abstract: Biological Purification of Waste Waters Abstract In the particular embodiments of the waste water treatment system described in the specification, a waste water treatment basin has spaced-apart, moving aerator chains extending across the basin in a direc-tion transverse to the flow of waste water through the basin.  When an aerator chain is provided with air, bottom aerators suspended from the chain adjacent to the bottom of the basin move with respect to the basin to mix sludge collected on the basin with the waste water and to supply air to the waste water.  A control system supplies air selectively to the aerator chains to provide zones of full aeration and intermediate zones with little or no aeration and the selection of the aerator chains is changed periodically in a pro-gressive manner along the basin so that the zones move progressively through the basin.  As a result, suffi-cient air is supplied to the waste water in the basin for purification of the waste water and to maintain sludge in suspension as required in the waste water at minimum expense of energy.  In addition, the oxygen potential of the waste water in the zones is con-trolled so that successive reactions relating to the purification process are accomplished in successive zones, for example, including nitrification of the waste water in zones having a relatively high oxygen potential and denitrification in adjacent zones having relatively low oxygen potential.  Phosphorus removal is accomplished in a similar manner.

Title: Preparation of ligand-polymer conjugate having a controlled number of introduced ligands
Inventor: YIP KIN FAI
IPC: G01N33/545
Filed: 1988-09-07
Granted: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE    A method for chemically coupling a control-lable number of ligands, e.g., haptens, to a poly-meric material by derivatization of the polymer with an activating agent to introduce a couplable functional group.  The derivatization is performed in the presence of a blocking agent which is reactive with the same functionality on the polymer as the activating agent.  By reacting the polymer with a mixture of a predetermined ratio of excess amounts of the activating and blocking agents, a controllable number of couplable functional groups are introduced to the polymer for subsequent linkage to the desired ligand.  The resulting polymer-ligand conjugates are useful as reagents in immunoassays, particularly immunoturbidimetric assays.
