Title: Method for preparing polyethylene wax by gas phase polymerization
Inventor: CHANG MAIN
IPC: C08F4/642
Filed: 1989-11-02
Granted: 2000-10-17
Abstract: This invention relates to a process for preparing polyethylene wax having a narrow molecular weight distribution in a gas phase polymerization reactor. The invention particularly relates to the process of polymerizing ethylene in the presence of a supported metallocene-alumoxane catalyst and hydrogen. The catalyst may be derived from the addition of silica gel containing about 6 to about 20 percent by weight adsorbed water to a trialkylaluminum solution. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. A trimethylaluminum pretreated metallocene may be employed when the trialkylaluminum is selected from the group consisting of triethylaluminum, tripropylaluminum, tri-n-butyl-aluminum, tri-isobutylaluminum, tri(2-methylpentyl)aluminum, trihexylaluminum, tri-n-octylaluminum and tri-n-decylaluminum.

Title: Dispensing cap with means for controlled flow rate and multiple seals
Inventor: SCHREIBER ALEXANDER R
IPC: B65D47/24
Filed: 1989-11-24
Granted: 1995-02-07
Abstract: The invention provides a twist open/close outer cap internally threaded to fit the threads on a special bottle neck in cooperative sealing attachment with an inner cap inserted into the bottle neck. Structural features and a stop provide bi-directional controlled rotation of the outer cap. A beveled top fluid release plug fitting a correspondingly beveled dispensing aperture and interacting insert structure provides excellent sealing characteristics. The outer cap is a short cylindrical member with an opened bottom and a shallow concave top surface. A flow directing inverted funnel-like protrusion is formed around a dispensing aperture in the center of the outer cap top. Depending from the underside of the outer cap top surface, is a cylindrical sleeve fitting a receiving chamber formed by two base attached walls in the second cap inserted into the neck of the bottle. Screwing the outer cap up and down on threads cooperative with neck threads on the bottle, opens and closes the dispensing aperture by inserting and withdrawing the plug fitting the aperture. The positioning of stops on the outer bottle neck surface and the inner wall of the outer cap control the dispensing opening and are set in manufacturing according to the viscosity of the material to be dispensed.
Patent CA-2009433-C (CA)
Inventor: KRESS DIETER
IPC: B23D77/04
Filed: 1990-02-06
Granted: 1999-02-02
Abstract: A reamer is proposed having at least one cutter plate that is held by at least one clamping jaw located in a recess in the head of the reamer and having an opening for a clamping screw.  The reamer is distinguished by the fact that the clamping jaw is shaped essentially as a triangle when viewed from the top, that the opening for the clamping screw is located in a corner of the triangle, and that the lateral surfaces of the clamping jaw starting from this corner form guide surfaces, which are provided with contact surfaces in the recess in the head of the reamer.  By using this clamping jaw, the cutter plate can be optimally clamped and aligned without weakening the main body of the reamer.  Both the flank and lateral surfaces of the clamping jaw interact with the stop surfaces in a recess in such a manner that optimal diversion of the clamping forces in the main body of the reamer also takes place.

Title: System for detecting voltage pulses of a particular magnitude
Inventor: COLLES JOSEPH H
IPC: G09G5/12
Filed: 1990-03-30
Granted: 1999-12-21
Abstract: SYSTEM FOR DETECTING VOLTAGE                PULSES OF A PARTICULAR MAGNITUDE                  Abstract of the Disclosure First circuitry on an integrated circuit chip has an input terminal, preferably the only input terminal, for receiving a voltage pulse introduced to a first terminal on the chip.  The first circuitry damps the negative voltage peaks of the voltage pulse at a voltage of a first magnitude inherent in the construction of the first circuitry.  A pair of input transistors in the first circuitry have dimensions to provide, at the input terminal to second circuitry, a clamping voltage of a first magnitude at a certain fraction of the power supply voltage.  The first circuitry may include a closed loop servo amplifier which regulates the negative peaks of the pulse at the input terminal to the second circuitry to a value approximately equal to the voltage of the first magnitude.  The second circuitry compares the negative peaks of the input voltage pulse with a voltage of a second magnitude inherent in the construction of the second circuitry to provide an output logic pulse.  A pair of input transistors in the second circuitry have dimensions to provide an internal reference voltage of the second magnitude.  Differences between the dimensions of the input transistors in the second circuitry and the first circuitry provide a slight but accurate difference between the voltages of second and first magnitudes.  The output pulse may constitute a horizontal sync pulse having amplitude not slightly more negative than the negative peaks of a color burst following it.  This pulse provides for a faithful reproduction of color from color information signals following the color burst signals.            * * * * * * * * *

Title: Nitrite-free meat curative and process of curing meat
Inventor: RUBIN LEON J
IPC: A22C13/00
Filed: 1990-08-24
Granted: 2004-03-23
Abstract: Dinitrosyl ferrohemochrome encapsulated in a film of edible polymer is used in a nitrite-free meat-curing process, to confer on the cured-meat product colour characteristics of nitrite-cured meats. The encapsulated DNFH is protected against oxidative degradation to enhance its shelf life, and is readily dispersible in aqueous pickle solutions. The encapsulating polymer is suitably an edible polysaccharide such as beta-cyclodextrin, preferably in admixture with other edible polysaccharides. The meat-curing system of the present invention additionally includes an antioxidant and an antimicrobial agent.      Comminuted meat products such as sausage meats and wieners are made by simply mixing in an appropriate amount of the encapsulated pigment as part of the curing process prior to further processing. Solid meat products such as hams are made by injecting or pumping into them pickle solution in which the encapsulated pigment has been dispersed.

Granted: 1999-02-16
Abstract: Disclosed is an improved system for the delivery of entertainment and educational programming from a plurality of electronic libraries to a plurality of users. Users actuate a hand operated control device to: review a listing of available programming; enable the delivery of a program from a library; or control the delivery of forwarding and rewinding through the programming, and authorizing the purchase of advertised consumer goods by entering in personal identificationnumbers. The network of libraries and the paths for delivering the programming stored therein is arranged for optimum transmission efficiency and maximum access capacity. The key idea in optimizing transmission efficiency and access capacity is to recognize that programming can be grouped into different classes,and that not all classes of programs should be stored in all libraries. High demand entertainment programming should be stored and delivered from a central source whereas low demand educational or cultural programming should be stored and delivered from a local neighborhood library where there is a special interest in such programming. The system is intrinsically secure and encryption is not required. Programs are not delivered to any physical address other than that of the ordering user. Apparatus is employed to discourage the unauthorized copying of delivered programming. The system also permits the delivery of conventional cable television signals on a competitive basis. Apparatus is employed that maximizes access capacity and minimizes investment cost.

Granted: 1996-12-17
Abstract: Only one pre-gap is arranged between the ignition coil and the distributor so that it is connected in series with each of the ignition plugs in the engine.  A relay device is connected in parallel with the pre-gap.          The relay device is normally closed to supply a high voltage from the ignition coil to the distributor, bypassing the pre-gap.  Only when sensor signals indicate that the air-fuel combustion state is bad, the relay device is opened to cause the high voltage from the ignition coil to be applied to the pre-gap before being supplied to the distributor.  This construction permits the single pre-gap to serve all the cylinders in the engine and prolongs the working life of the pre-gap.
