Granted: 1992-01-28
Abstract: ABSTRACT   A spherical fiber aggregate having an inner core and outer covering, in particular as a filler material for cushions and covers wherein individual filaments or fibers are intertwined, is characterized in that the core of the fiber aggregate contains filaments or fibers different from those of the covering. In this manner spherical fiber aggregates are created, which combine different properties, and in particular are capable of absorbing humidity when used as a filler material, and therefore contain natural fibers, while on the other hand they do not lose their down-like properties, such as high bulk, compressive elasticity,, softness, thermal insulation ability, light weight and ready adaptation to the body to be covered.

Title: Tuning device for rimless drums
Inventor: GAUGER GARY L
IPC: G10D13/02
Filed: 1988-01-04
Granted: 1991-04-23
Abstract: ABSTRACT            TUNING DEVICE FOR RIMLESS DRUMS     A tunable shell-less, rimless drum utilizes a multiplicity of tuning assemblies positioned about the frame of a pretensioned or untensioned standard drum head.  Each tuning assembly engages the frame and avoids tone impairing defamation of the drum during tuning so as to preserve the natural tonal quality of the drum.  A pivotably mounted lever at the bottom of the tuning assembly bears against a tuning band which engages the drum membrane, and cooperating notches on tuning band and lever retain the tuning band in a fixed position relative to the frame to prevent pitch variation or binding due to tuning band movement.  A threaded rod slides along a slot in the assembly and threadably engages a lock nut positioned within a nut confinement slot to prevent unwanted loosening of the rod.  The invention provides a tunable, compact, lightweight, rimless drum which has tuning convenience and tonal quality superior to most large, heavy shell type drums.

Title: Nucleophilic material modified for improved biocompatibility
Inventor: JOHNSON RICHARD J
IPC: C08B37/12
Filed: 1988-02-26
Granted: 1992-12-15
Abstract: NUCLEOPHILIC MATERIAL MODIFIED FOR IMPROVED BIOCOMPATIBILITY                            ABSTRACT A nucleophilic material is modified by reaction with a material having activated carbonyl groups, employing a nucleophilic-acyl substitution reaction which creates a non-ether linkage while retaining a free carboxyl group. Nucleophilic groups so modified lose their capacity to covalently bind C3b protein components.  The retained free carboxyl group favors the binding of protein factors H&I as well as cationic C3a and C5a anaphylatoxins.         A nucleophilic material modified as above stated also has the desirable characteristic of binding Beta-2-microglobulin and other poorly dialyzed molecules in the 1000 to 20000 molecular weight range.

Title: Vapor/liquid contact column structure
Inventor: PARKER TRENT J
IPC: B01D3/26
Filed: 1988-05-02
Granted: 1993-05-25
Abstract: VAPOR/LIOUID CONTACT COLUMN STRUCTURE                       A B S T R A C T            The disclosure is directed to a vapor-and-liquid contact structure for distillation, fractioning rectification, absorption, and the refining, in a column, of various liquid materials such as petroleum, chemical, and alcohol solutions.  Provision is made for the inclusion of vertically-spaced bubble plate chambers having respective liquid and vapor contact devices, to accommodate contact of counter-current flows of reflux liquid and vapors.  A downcomer means, including slanted ramps, is disposed outside of the vapor conduit-defining interior, and defines an elongate downcomer structure for liquid flow.  Accordingly, descending reflux liquid flow is kept outside of primary vapor flow, with secondary vapor evolving from descending reflux being conducted circuitously back into the primary vapor flow for ascent to the next-above contact device.  Plate efficiency is enhanced through maximum plate-area effective use and unidirectional liquid-flow over such plates.  Column sections are constructed in essentially identical modules which can be stacked and secured together to reduce fabrication and engineering costs.

Granted: 1993-10-12
Abstract: Abstract A method of packaging dry grout involving a novel aluminum product for use in packaged dry grout.   Aluminum flakes conventionally used  as  an expanding agent in a grout fluidifier are coated with a film which has limited sensitivity to the moisture and the alka1i(cement) in dry grout and are then blended with the materials(comprising cement) to be packaged as a dry grout for mixing with water to form a wet grout.   The coating used  is highly sensitive to the water and/or alkaline nature of the wet grout and readily deteriorates when the dry grout is mixed with water. A coating and binder, e.g., sodium silicate, may be used to coat the aluminum flakes and to adhere the aluminum to micro-particles, such as glassy microspheres, prior to a dry grout blending operation.

Granted: 1991-12-03
Abstract: A METHOD AND APPARATUS FOR INFREQUENT RADIO USERS TO SIMPLY OBTAIN EMERGENCY ASSISTANCE              ABSTRACT OF THE DISCLOSURE A digital mobile radio transceiver allows even the most unsophisticated user to simply and easily obtain emergency communications.  The transceiver is programmed with "personality" data specifying one or more "systems", each "system" specifying one or more "groups" of or individual radio transceivers.  Systems are selected by operating a first selector switch, and groups are selected by operating a second selector switch.  The transceiver simultaneously displays the "group" and "system" which have been selected.  One or more group identification codes uniquely designate an emergency communications handler (e.g., an emergency dispatch operator).  The group designated by the transceiver group selector switch position "9" of each system programmed into the radio transceiver corresponds to this emergency group identification code.  Moreover, the "system" designated by system selector switch "11" has only one "group" -- the emergency group identification code corresponding to the group selector position "9". Whenever the user operates the selector switches to select the group "9" and the system "11" (causing the transceiver to display "911"), the emergency group identification code is selected.  Similarly, whenever the user selects group "9" and any system, the emergency operator is selected; and whenever the user selects system "11", he can only select group "9" corresponding to the emergency operator.
