Title: Deactivation of ziegler catalysts in production of ethylene polymers
Inventor: ZBORIL VACLAV GEORGE
IPC: C08F2/42
Filed: 1986-01-28
Granted: 1989-01-12
Abstract: A solution polymerization process for the preparation of high molecular weight homopolymers of ethylene and copolymers of ethylene and C4 - C12 alpha-olefins comprises feeding monomer(s), coordination catalyst and inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320 DEG C and a pressure of less than 25 MPa, and deactivating the catalyst in the solution so obtained. The catalyst is deactivated by sequentialiy admixing therewith a minor amount of a deactivating agent followed by a solution of a salt of an alkaline earth metal or zinc and an aliphatic mono-carboxylic acid dissolved in hydrocarbon solvent. The deactivating agent is selected from carbon dioxide, carbon monoxide, dialkyl carbonate and dioxolones. The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered. The amount of said deactivating agent is not more than 2.5 moles of deactivating agent per mole of halogen plus alkyl radicals in the coordination catalyst.

Title: Polymer compositions containing oxygen scavenging compounds
Inventor: ZENNER BRUCE D
IPC: C08L23/00
Filed: 1993-10-13
Granted: 1998-02-12
Abstract: An oxygen scavenging composition or concentrate of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound may be an ascorbate compound or a polycarboxylic or salicylic acid chelate or complex of a transition metal or a salt thereof. The oxygen scavenging composition is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. A catalyzing agent is included in an amount sufficient to increase the rate of oxygen scavenging by the ascorbate compound. The oxygen scavenging compound may be added to the composition in a dry state, and is inactive until activated by contact with water or water vapor.

Title: Regeneration of coke contaminated catalyst
Inventor: GREENWOOD ARTHUR RAYMOND
IPC: C10G47/00
Filed: 1986-04-11
Granted: 1988-07-14
Abstract: Particulate catalyst which has been used in a hydrocarbon conversion process such as catalytic reforming is regenerated in a moving bed regeneration zone (12). The catalyst being regenerated is passed into the top of the zone (12) and slowly moves downward as a dense bed (14, 19, 20) which is contacted successively with an oxygen-containing gas stream (31), a temperature-adjusting gas stream (30) and either a drying gas stream (37) or a chlorination gas stream (39) or both at different elevations within the regeneration zone (12). A key feature involves employing a portion of relatively hot combustion gas (26) withdrawn from one portion of the zone (12) as the temperature-adjusting gas stream (30) in a different portion of the zone after compression, with the remainder of the compressed combustion gas (27) being cooled (32) and recycled to the combustion zone as the gas stream (31). This eliminates the need to employ a heater to provide a suitable heating gas stream.

Title: A process for producing a plug chamber in cascade drawing of tubes and device for practising the process
Inventor: EBERTS FRIEDRICH
IPC: B21C1/24
Filed: 1994-02-25
Granted: 1995-12-07
Abstract: Use is made of a device (15) with a clamping and denting unit (16) and with an end-expansion and ironing unit (17). A starting tube (1) is first of all fixed locally by means of the clamping and denting unit (16). An ironing ring (30) is then moved along a freely projecting end section (31) of the starting tube (1) with the aid of an ironing cylinder (22) of the end-expansion and ironing unit (17), and a mandrel (26) is then driven into the end section (31) with the aid of a mandrel cylinder (21) of the end-expansion and ironing unit (17). Once the mandrel (26) has reached its end position, in which the inside diameter and the outside diameter of the end section (31) are enlarged, the ironing ring (30) is drawn over the end section (31), the outside diameter being reduced to the original outside diameter of the starting tube (1). Following this, the mandrel (26) too is withdrawn from the end section (31) and two dents are produced on the outer circumference of the end section (31) of the starting tube (1) with the aid of the clamping and denting unit (16). Together with a drawing point produced by forming the free end of the starting tube (1), these dents form a plug chamber into which are embedded a plurality of drawing plugs that interact with drawing dies during the cascade drawing. <IMAGE>

Title: Efficient synthesis of musical tones having nonlinear excitations
Inventor: SMITH JULIUS O III
IPC: G10H1/12
Filed: 1996-05-10
Granted: 1998-12-17
Abstract: An efficient digital waveguide synthesizer is disclosed for simulating the tones produced by a non-linearly excited vibrational element coupled to a resonator, such as in a piano. In a preferred embodiment, the synthesizer creates an excitation pulse from a table containing the impulse response of a piano soundboard and enclosure. Alternatively, this excitation pulse can be synthesized by filtering white noise. The excitation pulse is fed into a filter that simulates the collision of the piano hammer and string. Because the hammer-string interaction is nonlinear, the characteristics of this filter vary with the amplitude of the tone produced. The filtered excitation pulse is then fed into a filtered delay line loop which models the vibration of a piano string. Because the excitation pulse already contains the effects of the resonator, the tone produced by the delay line loop does not require additional filtering in order to model the resonator.

Granted: 1993-08-12
Abstract: A female incontinence control device for insertion into the urethra includes a conduit (12, 92, 132, 182, 242) having a drainage inlet opening (14, 96, 136, 186, 246) to receive urinary fluid from the bladder, and an outlet discharge opening (18, 102, 166, 190, 250) positioned outside the urethra. The device also includes stabilizing structure for holding the conduit in its installed position relative to the urethra and bladder. The conduit (12, 92, 132, 182, 242) includes a manually actuatable drainage control valve (60, 110, 148, 198, 260) positioned outside the urethra. Manual actuation of the drainage control valve from a closed position to an open position is easily accomplished by manipulating an actuator member (80, 118, 164, 210, 268) at a distal end portion of the conduit to selectively control urinary discharge from the conduit. The actuator member can be formed as an extension of a valve member (62, 262) or interconnected with the valve member (112, 152, 200) through a flexible connecting link (120, 170, 212). The actuator member (164) can also be constituted as a flexible discharge member (150) which permits control of the direction of discharge of urinary fluid.
