Title: Use of acrylate copolymers as additives for aqueous cationic coating systems
Inventor: KRIESSMANN INGO
IPC: C09D5/44
Filed: 1990-09-04
Abstract: ABSTRACT OF THE DISCLOSURE         Acrylate copolymers containing amino, hydroxyl and fluorine groups useful as additives for aqueous cationic coating systems for preventing surface flaws and for improv-ing the adhesion of further coats, in particular of PVC-containing coating materials, are described.  In addition to amino groups which can be neutralized with acids, the acrylate copolymers contain a selected quantity of hydroxyl groups originating from monoesters of (meth)acrylic acid with diols, and fluorine from esters of (meth)acrylic acid.          The additives are added in a quantity from 0.5 to 5.0% by weight, calculated on solids and relative to the solids content of the binder in a coating system.

Title: Method of making a color picture tube electron gun with reduced convergence drift
Inventor: MANINGER LOREN L
IPC: H01J9/18
Filed: 1990-09-27
Abstract: An improved method of making a color picture tube electron gun includes the selection and assembly of a plurality of cathodes and a plurality of electrodes longitudinally spaced from the cathodes. The improvement comprises at least three additional steps. First, the amount and direction of electron beam misconvergence at the tube screen, as caused by the thermal expansion of each individual electrode during electron gun warmup, is determined. A first group of electrodes will cause misconvergence in a first direction, and a second group of electrodes will cause misconvergence in a second direction.      Second, the individual contributions of the electrodes to misconvergence during tube warmup are summed. The net effect of thermal expansion of the entire electron gun is a misconvergence in the first direction. Third, at least one of the electrodes in the first group of electrodes is formed from a material having a lower coefficient of thermal expansion than the coefficient of thermal expansion used in the first step of determining misconvergence caused by the thermal expansion of each individual electrode.

Title: Flavor enhancing and medicinal taste masking agent
Inventor: HUSSEIN MAMOUN M
IPC: A23L27/10
Filed: 1991-05-02
Abstract: ABSTRACT       Confections containing a volatile oil and designed for dissolving in the oral cavity containing novel volatile oil masking agents are disclosed.   The volatile oil masking agents significantly suppress the perception of unpleasant organoleptic sensations such as bitterness or medicinal off-taste initiated by the volatile oil being released in the oral cavity.  Masking agents such as fenchone and d-borneol are present in the confection in sensorially undetectable amounts to provide masking of unpleasant characteristics of volatile  oils  without  detracting  from  the  desired organoleptic sensations of taste and the perception of vapor action in the oral cavity.

Title: Aircraft lock for radios, power controls, and flight controls and method
Inventor: TORRES RAMON L
IPC: B64C13/14
Filed: 1991-06-11
Abstract: ABSTRACT OF THE DISCLOSURE    The use of a center lock bar which telescopingly receives two telescoping arms, each of which has a control column or shaft grip on its remote end is disclosed.   The arms are secured to the parallel control columns by at least one gust lock pin.  Provision is made for a throttle mixture lock plate to be secured to the lower portion of the radio lock pan which, in turn, has essentially parallel sidewalls with opposed openings through which the center lock bar passes.  Optionally folding extension radio lock pans may be employed for a double stack installation.  Finally, means are provided in the form of a lock, whether padlock or internally mounted,  to lockingly secure the center lock bar to the two telescoping arms.  The method of the invention looks to providing a lock for radios, throttles, and gust locks in a dual control aircraft by stabilizing the two control columns by means of a telescoping  member  which  can  accommodate  differences  in  the distance between the parallel control columns of the aircraft.  The step in addition to the foregoing of locking is done by securing at least  one  pin  to  one  of  the  parallel  control  columns,  and thereafter mounting a central radio stack and throttle control centrally of the central portion of the lock.   Once these steps have been followed, a lock removably secures the center lock bar against movement relative to the radio lock pan and the flight controls as well as engine controls.
Patent CA-2045078-A1 (CA)
Inventor: ABYS JOSEPH A
IPC: C25D5/04
Filed: 1991-06-20
Abstract: Electrodeposition in surface finishing as well as in electroforming can be performed in a broad range of hydrodynamic conditions. In some instances, such as barrel plating, the liquid is barely moving relative to the work piece, while in jet plating the solution moves up to several meters per second relative to the piece to be plated. In such a wide range of hydrodynamic conditions, the selection of appropriate quality control (QC) methods for each particular operation is very critical. The QC method has to resemble the manufacturing operation in terms of the hydrodynamic conditions otherwise the quality control and the functional test for the bath performance have no meaning. Available Hull Cell systems have a limited capability in varying the liquid velocity. At best a relative velocity of up to 20 or perhaps 30 cm/sec can be achieved with uneven distribution.          The invention provides, in electroplating QC methods for manufacturing, better similarity and relevance between a Hull Cell QC test and aparticular plating operation. The invention is a simple and yet functional instrument which can be used to identify the performance of the plating bath prior to manufacturing operation under similar hydrodynamic conditions. The instrument isa rotating cylinder with a flexible Cu test panel attached to its surface. Like a Hull Cell, a range of current density can be simultaneously applied. Unlike a Hull Cell, the rotating speed of the cylinder and hence the solution agitation is practically unlimited The operator can identify the operating window for the particular process and apply them to the production line. The instrument has also demonstrated usefulness in developing proprietary electroplating chemistries.

Abstract: A wall means intended for apparatus for separation of a liquid-containing portion from a liquid-containing particle material which is fed through the apparatus in a predetermined direction (A).  The wall means comprises a plurality of bar profiles defining continuous slots between them to allow through the liquid-containing portion.  According to the invention each bar profile has on its inner side facing the liquid-containing particle material a ridge portion extending between the ends of the bar profile and being provided with two continuous guide surfaces which, as seen in a cross section of the rod profile, are inclined in relation to the drainage direction (B) of the liquid-containing portion through the adjacent slot.  Furthermore, the inclined guide surfaces in their longitudinal direction are disposed to coincide with the predetermined direction of feed (A) of the liquid-containing particle material in order to influence the liquid-containing particle material to maintain this direction of feed (A).

Title: Apparatus for detecting transducer movement
Inventor: JONES PAUL H
IPC: G01P13/00
Filed: 1991-10-03
Abstract: APPARATUS FOR DETECTING TRANSDUCER MOVEMENT                 Abstract of the Disclosure An apparatus for photo-optically detecting transducer motion using a photodetector resiliently suspended inside the transducer housing and photo-optically coupled to a light source. During movement the inertia effect of the photodetector along with the resilient suspension system causes the changes in the photo-optical coupled between the photodetector and the light source. The inertia effect of the photodetector is enhanced by adding a mass to the photodetector. Either the magnitude or the phase of the photodetector output is monitored to detect movement. In another embodiment, a light emitter is resiliently suspended so that movement induced changes in the position of the light emitter alter the coupling of light to one or more light detectors.
