Granted: 1991-03-12
Abstract: A B S T R A C T                 SMECTIC LIQUID CRYSTAL DEVICES            A liquid crystal display (1, 20) is arranged to provide very low minimum light transmittion in one of its two switchable states. This makes it useful for a shutter (Figure 1) and for high contrast digital displays (Figure 2).   A layer 14 of a chiral smectic liquid crystal material is contained between two cell walls (9, 10) carrying electrode structures (11, 12).   The liquid crystal material has the following phases with temperature:-isotropic   cholesteric   chiral smectic   solid. The cholesteric pitch is large.   The cell walls are surface treated to provide a parallel alignment of liquid crystal molecules.   Crossed polarisers (2, 3) are arranged either side of the cell walls, one (2) aligned with its optical axis parallel to the surface alignment of the adjacent cell wall (9).   The device is switched (5, 5) by means of +/- d.c. voltage pulses and utilises the ferro electric effect.

Title: Horizontally disposed apparatus for the random distribution of seeds and granular materials
Inventor: POPOWICH STANLEY
IPC: B65G53/52
Filed: 1987-04-28
Granted: 1991-08-06
Abstract: Abstract The   farm   implement   for   distributing particles such as seeds or granular fertilizers has an  apparatus  for  splitting  a  single  particle-entraining air stream into a plurality of indivi-dual streams containing uniform and randomly divided quantities  of  particles.    The  apparatus  has  a horizontally disposed corrugated pipe in downstream communication  with  the  conduit  for  providing  a uniform flow of particles to a horizontally dis-posed, tubular, stream splitting distribution body. The distribution body has a transition section that progressively and symmetrically changes in a down-stream  direction  from  a  circular  configuration toward a generally flat, rectangular configuration, a generally flat transfer section that leads from the transition section and spreads symmetrically laterally outwardly in a downstream direction, and a single  layer of generally horizontally disposed outlet tubes at the downstream end of the transfer section.  The distribution body flattens and widens the stream from a generally circular in cross-section stream entering the circular inlet to a generally shallow and wide uniformly distributed stream that flows into the entry apertures of the layer of outlet tubes wherein the stream is appor-tioned  among  the  apertures  into  a  series  of substantially identical smaller streams.

Abstract: ABSTRACT            METHOD OF APPLYING COSMETICS TO A SUBSTRATE AND ARTICLE         A unique system for distributing and sampl-ing cosmetics is disclosed.  The cosmetics which are normally dry, are combined with a liquid carrier and film forming agent and deposited onto a substrate.          The film forming agent acts to microencapsulate the cosmetic and lightly bond the cosmetic to the sub-strate.  When the film forming agent dries, it protects the cosmetic.  Thus, the cosmetic can be applied to a substrate and covered with a paperboard sheet.  Access to the cosmetic can be provided by a tear strip.  Greasy cosmetics, such as lipstick, can also be applied to a substrate according to the present invention.  These cosmetics are first microencapsulated with gelatin and the formed microparticles are secondarily encapsulated with a film forming agent and deposited onto a substrate.          This method permits cosmetics to be distributed through the mail and as magazine inserts and the like.

Granted: 1990-10-30
Abstract: A METHOD AND APPARATUS FOR OPTIMIZING SYSTEM OPERATIONIAL PARAMETERS    THROUGH PROJECTIVE TRANSFORMATIONS            Abstract Method and apparatus for optimizing the operational state of a system employing iterative steps that approximately follow a projective scaling trajectory or an affine scaling trajectory, or curve, in computing from its present state, ?0 to a next state ?1 toward the optimum state. The movement is made in a transformed space where the present (transformed) state of the system is atthe center of the space, and the curve approximation is in the form of a power series in the step size. The process thus develops a sequence of tentative states ?1, ?2, ?n.... It halts when a selected suitable stopping criterion is satisfied, and assigns the most recent tentative state as the optimized operating state of the system.
