Title: Linear viscoelastic aqueous liquid automatic dishwasher detergent composition
Inventor: ROUNDS RHYTA
IPC: C11D3/08
Filed: 1990-04-23
Granted: 2001-02-13
Abstract: Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improve physical stability.

Title: Improved call set-up in a radio communication system with dynamic channel allocation
Inventor: STRAWCZYNSKI LEO
IPC: H04W24/00
Filed: 1990-10-17
Granted: 2000-02-15
Abstract: IMPROVED CALL SET-UP IN A RADIO COMMUNICATION SYSTEM WITH              DYNAMIC CHANNEL ALLOCATION            Abstract of the Disclosure The call set-up technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen.  Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal.  The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference, as measured by the base station.  The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.

Abstract: A catalytic cracking process and apparatus therefor are de-scribed, wherein hot, active cracking catalyst particles are circulat-ed from a regenerator (12) to a reactor (11) wherein they are brought into contact with a hydrocarbon feed to convert the latter to cracked products. The cracked products and resultingly spent catalyst particles are separately recovered and the spent particles are passed to a stripping zone (22) for contact with a stripping gas to remove therefrom strippable hydrocarbon materials, which also are recovered. The stripped catalyst particles are circulated to the regenerator (12) for contact with an oxygen-containing gas to reactivate and heat them before recirculation to the reactor (11).    At least some of the hot regenerated catalyst particles are passed through an indirect heat exchanger in indirect heat exchange with at least some of the stripped catalyst particles whereby the former are cooled and the latter are heated. The regenerated catalyst which contacts the feed is thus cooler than it would otherwise be, and there is a reduction in thermal cracking. The stripped catalyst entering the regenerator is hotter than it would otherwise be there-by improving the efficacy of the regeneration step.
