Title: High loading of immobilized enzymes on activated  carbon supports
Inventor: BAILEY JAMES E
IPC: C12N11/06
Filed: 1978-10-02
Granted: 1982-08-10
Abstract: ABSTRACT OF THE DISCLOSURE             Enzymes are immobilized on activated carbon supports at high load levels and with high stability by a procedure whereby a carbon support is first activated with a water-soluble carbodiimide derivative which forms a highly reactive intermediate with carboxyl and other active organic radicals on the surface of the carbon support; thereafter the complex of the carbon and carbodiimide is treated with an enzyme solution whereby the enzyme displaces the quaternary ammonium group and forms a carbon-enzyme complex wherein the enzyme is immobilized and yet the carbon retains its surface activity. Preferred immobilizing agents are quaternary ammonium forms of aminocarbodiimides or hydrochloric acid salts of water-soluble carbodiimides. The immobilization of the enzymes on activated carbon provides materials which are easily handled and which are stabilized against denaturation by hydrogen peroxide, thus stabilizing the immobilized enzymes.

Abstract: Abstract of the Disclosure An imaging system, particularly useful for acoustic medical diagonsis of a human subject, utilizes an array of radiating elements or sonic transducers located side-by-side and positioned along the subject.  Signals received by the transducer are applied to a pair of pattern generation circuits which weight the in-dividual signals by factors of +1, -1 or 0.  Graphs of the weighting factors as a function of transducer location have the likeness of cosinusoidal and sinusoidal Fresnel patterns, these patterns being produced by the two circuits.  The weighted signals of each pattern are summed together, multiplied by cosinusodial and sinusoidal reference signals and then summed together to provide a radiation pattern which converges from the array to a focal point in front of the array while eliminating a diverging pattern from a virtual focus behind the array.

Abstract: Abstract of the Disclosure A readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters.   A warping ring receives there-within a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which extends into one of the longitudinal corrugations.  The size of the tube produced can be varied by merely substituting a warping ring of a different size.  A uniquely shaped pair of die-forming rollers have lock-seam forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque.  The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes.  The lock is provided by its radially extending deformations in its longitudinal medial portions and terminal portions, with intermediate portions therebetween extending at about 60 degrees thereto.  The terminal portions extend around the bottoms of each of the U-shaped seam elements to further lock them in place.  A flying saw automatically cuts off predetermined lengths of the tubing.  The length of the sections to be cut may be varied by merely re-positioning a movable switch in the path of the tube.  The tube has a unique lock-seam which is constructed to withstand greater flexing, greater axial twist and more stress without damage and without opening, and is stronger.

Abstract: ELECTRICAL RIBBON CONNECTOR AND HOOD               ABSTRACT The present invention is directed generally to an im-proved electrical connector and an associated hood used to house or enclose the terminating section of the connector.  Prior art electrical connectors are limited in the manner in which the pro-tective hoods are assembled and disassembled from the connector body which, in turn, limits the way in which the connector can be mounted or located within the associated electrical or tele-phonic equipment.  Moreover, in those connector constructions which incorporate self latching hood structures, it is sometimes difficult to unlatch the hood from the connector body and special tools are required in some instances to facilitate the disassem-bly of the hood from the connector body.  The present invention overcomes these deficiencies of the prior art by providing a pro-tective hood which is assembled to or disassembled from a locked position on the connector insert member by either a sliding or pivoting technique.  The hood is also automatically locked or secured in its final assembled position, and the locked or latched structure may be easily disengaged using a simple prying device such as a screwdriver.  The connector body or insert mem-ber also includes retent structure for maintaining the plug and receptacle connectors in fully mated assembly but which also pre-vents contaminants from reaching the interior of the fully mated connectors.
