Abstract: ABSTRACT             ELECTRICAL CONNECTOR            Connection is made to an insulated conductor by the connector of the invention without the need to pre-strip the conductor.  The connector comprises two contact members that overlap to provide an aperture for receipt of the insulated conductor.  The connector is recoverable, preferably by means of a memory metal strip, to cause the contact members to slide relative to each other to reduce the aperture size, pierce the conductor insulation, and exert a permanent gripping force on the conductor.

Abstract: 5711(2) ABSTRACT OF THE DISCLOSURE     This invention relates to a process for producing polyisobutene which has at least 70% of its unsaturation in the terminal position.  The process uses a complex of boron trifluoride and alcohol as catalyst and a contact time of at least 8 minutes.  The feature of the process is its ability to use longer contact times than used hitherto thereby facilitating its commercial operation and improving the control of such an operation.  The high terminal unsaturation improves the reactivity of the polymer.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention provides a stable, conven-ient solid state test device for the determination of ethanol in an aqueous test sample, a method for its pre-paration and a method for its use.  The use of carrier matrix incorporated with alcohol oxidase, a peroxida-tively active substance and a suitable chromogenic indicator for the determination of ethanol in aqueous samples such as body fluid samples (e.g., serum, urine or saliva) is part of the invention.  The invention provides a method of incorporating the enzyme alcohol oxidase and a peroxidatively active substance into a carrier matrix with a chromogenic indicator system capable of providing a detectable response to the presence of at least 100 mg/dL ethanol in less than about 5 minutes.  The method involves either a) the use of a specialized incorporation procedure or b) the addition of an azide to the test device.  Either method overcomes the "false positive" problem seen when solu-tion assay reagents are incorporated at the increased concentrations necessary to provide a test device sensitive to the at least 100 mg/dL ethanol.

Abstract: ABSTRACT OF THE DISCLOSURE The extruder head for extruders for thermo plastic and heat-settable masses has been made to be opened in various ways in order, for cleaning purposes, to make more accessible the inner flow channels which lead to the mouth piece which is provided with the extrusion nozzle. The opening mechanisms of such so-called folding or hinged extruder heads must be able to absorb the relatively high material pressures without being destroyed and also without being unduly deformed. This has previously always lead to very large and sturdy constructions with the drawbacks of high weight, high manufacturing costs and poor accessibility. The present invention circumvents the stress require-ments by pressing the pivotable parts of the ex-truder head against the stationary extruder head via elastically yieldable spring elements, preferably in the form of pressure medium cylinders. By apply-ing thermal insulation to the extruder head parts, the pressure medium cylinders can be shielded from the undesirable effect of thermal convection.

Abstract: ABSTRACT OF THE DISCLOSURE      A uni-directional/bi-directional sealing gate valve comprises a valve body with a float passage and a valve gate chamber intersecting the flow passage.  A valve gate in the chamber controls fluid flow through the valve.  The gate has a flow passage extending therethrough for cooperation with the body flow passage to permit fluid flow through the valve when the gate is in a first position.  When the gate is in each of second and third positions, a device prevents fluid flow through the valve. A fluid tight seal is provided between the valve gate and the valve flow passage.  A pressure relief is provided in the valve gate for permitting escape of pressure from the gate chamber into the body flow passage when the gate is in one of the second and third positions.  The pressure relief prevents the pressure escape when the gate is in the other of the second and third positions.  The gate valve is particularly useful in controlling flows of materials at elevated temperatures and pressures.
