Abstract: TITLE          Rotational Control Apparatus ABSTRACT OF THE DISCLOSURE        A rotational control apparatus is shown in its most preferred form according to the teachings of the present invention as a combination clutch/brake.  The clutch/brake includes an interfacing member formed by first and second pressure plates rotatably mounted but reciprocally related with respect to each other.  The interfacing member is reciprocated between one of first and second disk packs by an actuating rod reciprocally mounted in the housing and interconnected to ears formed on the second pressure plate.  The actuating rods are reciprocated by actuation canisters located on opposite ends thereof.  Each of the actuation canisters includes a piston which is reciprocated by a fluid chamber and a spring located in the fluid chamber.  In the first preferred form, the springs of the canisters have a compressional force which are equal and less than required to actuate the clutch/brake such that in the absence of fluid pressure, the actuating rod and interfacing member is in a normal, neutral condition.  In another preferred form, the spring of one of the canisters has a compressional force sufficient to actuate the clutch/brake in a normal set condition.  Fluid pressure may be electively introduced into the fluid chamber to assist the actuation force spring to return the piston to its set condition and at greater actuation forces.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for the modification of crystalline polymers of propylene is disclosed.  A major portion of particles of the propylene polymer is admixed with a minor portion of particles of a composition of a normally solid second polyolefin and an organic peroxide.  The second polyolefin, which is a homopolymer of hydrocarbon alpha-olefins having 4 carbon atoms or copolymer thereof with a minor amount of ethylene, has a shear viscosity that is not more than 30% of that of the propylene polymer.  The organic peroxide has a half-life at 150°C of from 1-120 minutes.  The admixture is mixed at a temperature above the melting point of the propylene polymer and second poly-olefin for a period of time that is at least four times the half life of the organic peroxide at the temperature of mixing.  The resultant polymers exhibit improved processability while retaining useful physical properties, for example for injection moulding end-uses.

Title: Process for the preparation of vinylphosphonic dichloride
Inventor: SIEGEL HERBERT
IPC: C07F9/42

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a process for the preparation of vinylphosphonic dichloride, in which a 2-chloroethane-phosphonate of the formula                or   or a mixture of the two esters, is reacted with thionyl chloride at a temperature of 60 to 160°C in the presence of a catalyst which contains tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkaline-earth metal halides.            During this reaction, any thionyl chloride which may be present is removed by distillation subsequent to this re-action, the mixture remaining is heated to 140 to 200°C, and the vinylphosphonic dichloride produced during this is removed by distillation.

Title: Molecules with antibody combining sites that exhibit catalytic properties
Inventor: TRAMONTANO ALFONSO
IPC: A61K39/00
Filed: 1987-09-16
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE        An analog-ligand having a conformation that substantially corresponds to the conformation of a hydrolytic transition state of an amide or ester reactant ligand is used to produce receptor molecules of predetermined specificity.  The receptor molecules include an antibody combining site that binds to a reactant ligand and thereby stabilizes the tetrahedral carbon atom of the amide or ester hydrolysis transition state of that reactant ligand to catalytically hydrolyze the reactant ligand at a predetermined site.

Abstract: The well water removal and treatment system of the present invention includes a pumping and well water withdrawal loop consisting of an above ground pump, a pressurized water drive line from the pump outlet to a well water ejector, a water return line from the well water ejector to an aeration and precipitation tank, an inlet line from the aeration and precipitation tank to the pump and a venturi nozzle air mixing manifold fluidically connected between the high pressure drive water line and the lower pressure water delivery line to mix air into the water during the entire pump cycle. The water delivery line from the pumping and withdrawal loop has a flow control regulator therein that controls the water flow therethrough in proportion to the water pressure in the pumping and withdrawal loop above a preselected minimum control level. Until the water pressure exceeds the minimum control level, the water repeatedly cycles through the pumping and withdrawal loop and thereafter most of the water repeatedly cycles through the loop until the pump is deactuated.
