Patent CA-2062545-A1 (CA)
Inventor: FICKER CHARLES
IPC: C09D7/00
Filed: 1992-03-09
Abstract: A paint detackification treatment for paint spray booths include a water soluble polymer which is a dicyanadiamide formaldehyde condensation product in combination with a multivalent metal salt, preferably aluminum chlorohydrate.  The composition is added to the overspray collection tanks and acts to detackify particles of paint which are collected in a water curtain.  The combination of the dicyanadiamide formaldehyde and aluminum chlorohydrate permits a lower concentration of polymer to be used and also permits this detackification product to be used with a wide variety of aqueous and oil based paints.

Title: Paging system with energy efficient station location
Inventor: PEEK WILLIAM H
IPC: H04B1/08
Filed: 1990-06-07
Abstract: A method for searching for a station carrying paging data without un-duly draining the paging receiver battery. If a station to which the receiver is presently tuned becomes unreliable, the pager scans among channels listed in a local channel list. If no paging data is received on these channels, the scan-ning among the local list channels may optionally proceed for a further inter-val at a slower rate. After it appears that paging data will not be found on channels listed in the local list, the pager begins a full spectrum search at a slaw rate until it again finds a channel carrying paging data. By this arrange-ment, battery power is expended at a rate roughly in accordance with the likeli-hood of ending a paging station.

Filed: 1993-02-10
Abstract: An apparatus and method for the nonplanar treatment of  a  volumetric  workpiece  or  substrate  utilizing exposure beam lithography are disclosed.   The method includes supplying one or more layers of one or more semiconductor materials to surfaces of the substrate, applying a resist over the semiconductor layers, setting the resist, and then directing an exposure beam, such as an electron beam, toward the substrate.  The substrate is  then moved  in  at  least two  degrees  freedom  of movement,  relative to the beam,  with one degree of freedom of movement being the rotating of the substrate about an axis generally perpendicular to the beam.  The other degree of freedom of movement could be moving the substrate linearly in a direction generally parallel to the axis.  By such movement, the resist is exposed to the beam in a predetermined pattern.  The exposed resist is then developed and a  layer or  layers under the exposed resist are etched.  The remaining resist is then removed yielding the desired semiconductor device.

Title: Thermoplastic composition and method of making
Inventor: SEELEY PETER
IPC: B29B17/00
Filed: 1993-07-07
Abstract: ABSTRACT OF THE DISCLOSURE       A plastic composition and a method of making the composition are disclosed.  The composition consists of a solid matrix which includes high density plastic particles bonded together by a low density plastic which conformally coats the high density particles. The composition may be made using a low performance heated press having a potential for heating a mold to about 325°F. and exerting a pressure of about 350 psi.  The composition is preferably made using 100% recycled plastic, unwashed recycled engine oil containers being the preferred material for the high density component and recycled shrink wrap being the preferred material for the low density component.  To make the composition the high density and low density components must be ground into particles and proportionally blended in a substantially homogeneous mixture.  If both the high density and low density components are dry plastics, an agent for promoting an adhesion between the components must be added so that a substantially homogeneous mixture of the components can be obtained.  The preferred agent for promoting that adhesion is used engine oil, preferably applied to the high density particles after grinding.

Title: Scanning of moving objects using unique rotating polygon mounted on carousel which rotates at twice polygon's speed
Inventor: SCHWARTZ NIRA
IPC: G02B5/09
Filed: 1991-11-01
Abstract: A polygon (11) for reading and writing information, and tracking industrial products on a rotating carousel (27) is arranged so that each of its sides (12-17) behaves effectively like a mirror mounted directly on a rotation axis (10) of the polygon (11). When this polygon (11) is installed in the center of rotating carousel (27), it can perform accurate tracking of objects on the carousel (27) with a constant (fixed) rotation speed (.omega.p) equal to half of the rotational speed (.omega.c) of the carousel (27).  The designs employ a polygon (11) with side mirrors (21) tilted in an arbitrary angle (.alpha.) with surrounding mirrors (opposite-side mirrors (22)) either tilted at a right angle (.beta.) or at an angle .alpha./n (where n is an integer) with respect to the tilted side mirrors (21) of the polygon (11). The designs of these polygons (11) eliminate all the unwanted effects of off-axis side mirrors which exists in standard polygons. This is done by producing an optical path that is equivalent to the optical path of the scanning mirrors so that their plane contains the rotational axis (10) of the system.
