Abstract: A process for recovering double metal cyanide complex catalyst from a polymer such as polypropylene glycol in a form suitable for use as a polymerization catalyst is described. The process comprises the steps of (a) combining the polymer with a non-polar solvent to precipitate the catalyst and (b) filtering the resulting mixture in the presence of a filter aid to separate the polymer from the precipitated catalyst. In contrast to the prior art methods of catalyst removal, the process of the invention yields polymer uniformly low in color as well as recovered catalyst which may be reused in subsequent polymerizations.

Abstract: ABSTRACT.          A rig battened with standoff battens presents a concave camber towards the wind on both tacks while remaining on one side of the mast as each batten comprises a member of a rigid leading portion connected to a flexible portion continuous to a semi rigid trailing portion. A holder attaches to the leading portion and the trailing portion to hold off the batten with presprung bow like arms.          A ring part of the holder fixed on the opposite side from the arms attaches the batten assembly to the mast. Lines lead from the winch to the points at which the holder attaches to the batten such that on winching the arms are drawn back and the rig flattens out.          Additionally the conection between the lead and the flexible center can be pined and the connection between the holder and the rigid leading part can be pined to an adjustable bracket part of the leading portion to enable it the leading portion to move out of curve with the batten to amplify the camber of the rig.            ;

Title: Forage treatment, granular material distributor
Inventor: BAUER FRANCIS C
IPC: A01F15/08
Filed: 1990-07-12
Abstract: TITLE Forage Treatment, Granular Material Distributor ABSTRACT OF THE DISCLOSURE       A distributor of granular material for the treatment of forage is disclosed including an air manifold suspended by a parallelogram system from a dispenser. The lower ends of the arms of the parallelogram system are pivotably and slideably mounted to the manifold by bolts extending from the air manifold through apertures formed in the arms to allow the air manifold to slide as the metering rate of the dispenser is adjusted.  The discharge tubes for the granular material terminate beyond and below the air tubes of the air manifold.  The free ends of the air tubes are inwardly radiused to create a protrusion for directing air flowing in the air tube longitudinally past and around the discharge tube laterally towards the free end of the discharge tube to create a partial vacuum at the free end of the discharge tube to prevent the granular material from clogging the space between the discharge and air tubes.  The air inlet of the fan is located intermediate but off center of the first and second air tubes to provide even air flow therethrough.  The flowing air including the suspended granular material it dispersed by smooth bore plastic hoses connected intermediate the air tubes and spreaders. In a first form, the spreader is a 90° street plumbing elbow and in an alternate form, the spreader is in the shape of a duck foot including an inlet oriented at an angle in the order of 45° to an impingement plate having upstanding, radially extending and circumferentially spaced, vane plates.

IPC: B01D11/02
Filed: 1990-09-19
Abstract: A method to extract and recover plasticizers and their stabilizers from solid propellants, explosives, and pyrotechnics (PEP source compositions) employs near critical liquid (NCL) or supercritical fluid (SCF) CO2 as the solvent.          The extraction and ingredient recovery method provides an environmentally acceptable alternative to traditional open burning and destruction of PEP source compositions.  CO2 solvent is nontoxic, nonflammable, noncorrosive, inexpensive, and does not generate any additional toxic or hazardous wastes.  The solvent is totally inert when it is confined, pressurized, and possibly heated in direct contact with an energetic propellant or munition within a rocket motor or similar pressure vessel.

Title: Method and apparatus for serial data flow control
IPC: H04L12/56
Filed: 1990-09-19
Abstract: Method and Apparatus for Serial Data Flow Control A data flow controller (150). A serial communications card (11) provides an interface between a remote transmitter connected to a serial port connector (20) and a host device (10). The card (11) contains a UART (14) which has a buffer. A counter (151) counts the number of bytes received by the UART (14) since the last time that the host (10) read all the data in the buffer. If the number exceeds a predetermined portion of the buffer capacity the counter output (Q11) will go high, thereby disabling the counter and sending a control signal (DTR, RTS) to the remote transmitter to stop sending data. Once the host (10) has read all the data in the buffer the UART (14) provides a signal (-RXREADY) which resets the counter (151), thereby causing the output (Q11) to go low, thereby allowing the remote transmitter to resume sending data. The counter (151) is held in a reset state until the buffer has received at least one byte of data. Data flow control is therefore obtained without the intervention of the host (10).

Inventor: MINSHALL BILLY W
IPC: A61M1/02
Filed: 1990-03-05
Abstract: A sterile product and a method for sterilizing and assembling such a product are disclosed wherein the product has two or more portions, such as a medical fluid containing portion (12) and a flow control apparatus portion (14), which are mutually incompatible with regard to the method of sterilization. The sterile product is preferably produced by exposing one portion of the product, e.g., the flow control apparatus (14), to a first form of sterilization such as an electron beam, while shielding the other portion of the product, e.g., the medical fluid containing portion (12), from the first form of sterilization. The product may be integral, with the step of sterilizing the first portion occurring while the other product portion remains attached in close association therewith. The present invention has particular application in association with a product having first and second incompatible portions (12 and 14) which are joined by a flow path. In such a product, each product portion and its respective low path portion may be sterilized in the appropriatemanner. The flow path may then be isolated from the respective product portion and the flow paths joined together. Subsequent to joinder, the isolated portion of the flow path may be sterilized, as by electron beam, while any product portion incompatible with such form of sterilization is shielded from the effects of the sterilization.

Filed: 1990-11-28
Abstract: ABSTRACT            The invention relates to a method for producing zinc from oxidic zinc raw materials by reducing them in carbonaceous iron melt. In the method the zinc raw material is injected, together with a carbonaceous reducer, into the iron melt, so that the oxidic zinc is reduced and volatized as metallic vapour.  This vapour is discharged from the iron melt to-gether with the carbon monoxide released in the reduction reaction and the carrier gas, and is conducted out of the reactor into a separate condenser, where the zinc is recov-ered by condensing.

Title: Subroutine return prediction mechanism
Inventor: STEELY SIMON C JR
IPC: G06F9/42
Filed: 1990-12-14
Abstract: ABSTRACT OF THE DISCLOSURE       A method and arrangement for producing a predicted subroutine return address in response to entry of a subroutine return instruction in a computer pipeline that has a ring pointer counter and a ring buffer coupled to the ring pointer counter. The ring pointer counter contains a ring pointer that is changed when either a subroutine call instruction or return instruction enters the computer pipeline. The ring buffer has buffer locations which store a value present at its input into the buffer location pointed to by the ring pointer when a subroutine call instruction enters the pipeline. The ring buffer provides a value from the buffer location pointed to by the ring pointer when a subroutine return instruction enters the computer pipeline, this provided value being the predicted subroutine return address.
