Abstract: Abstract of the Disclosure Disclosed is a method of assaying a high concentration of a substance in a liquid sample with a polarographic cell.  The cell contains an electrode assembly that includes a reference electrode and a hydrogen peroxide sensor electrode having a laminated membrane covering the liquid sample contacting face of the sensor electrode.  The laminated membrane includes an outer membrane permeable to the substance and oxygen, an inner membrane permeable to hydrogen peroxide and located adjacent the face of the sensor electrode, and an enzyme layer between the inner and outer membrane; the enzyme in the enzyme layer can oxidize the substance to generate hydrogen peroxide. The method includes contacting the outer membrane with the liquid sample; permitting the substance and oxygen in the liquid sample to pass through the outer membrane to contact the enzyme layer so that where the substance is oxidized to generate hydrogen peroxide; permitting the generated hydrogen peroxide to pass through the inner membrane to contact the sensor electrode; and ensuring that the supply of oxygen in the enzyme layer relative to the supply of glucose is sufficient to produce an equilibrium concentration of hydrogen peroxide, which generates a steady state response at the sensor electrode proportional to the concentration of the substance in the liquid sample.

Abstract: A needleless injector device includes an integral unit that is dimensioned and arranged to be grasped in the hand of a user, loaded with a selected dosage, and held proximate the skin in order to inject the selected dosage in a high pressure jet sufficient to pass the selected dosage through the skin for injection purposes, the unit having a barrel portion, a gas storage portion, and an intermediate portion.  A trigger operates a release mechanism to release compressed gas from a storage compartment to act upon a piston and drive a plunger that ejects the selected dosage of medication through an aperture in the discharge end of the barrel portion, the piston face being larger than the plunger face to increase pressure.  A dose dispenser combines with the injection device in a system adapted for use with an insulin or other conventional vial and the dose dispenser may include a vial adapter or the combination of a vial coupler and a transporter/loader device designed to pierce the self-sealing lid on the vial and to facilitate more precise dosage transfers.

Title: Preparation of ultra-high molecular weight polyester
Inventor: COHN GERALD
IPC: C08G63/78
Filed: 1989-03-30
Granted: 1994-06-21
Abstract: Abstract of the Disclosure PREPARATION OF ULTRA-HIGH MOLECULAR WEIGHT POLYESTER   There is a growing demand for high molecular weight polyester resin.  For instance, the market for high molecular weight polyethylene terephthalate resin is rapidly expanding.  High molecular polyethylene terephthalate resin is currently being used in vast quantities in manufacturing bottles for carbonated beverages, trays for frozen foods which can be heated in either microwave ovens or convection ovens, and in tire cord.  There is a growing trend toward higher molecular weights in many applications for such polyester resins.  Unfortunately, it becomes progressively more difficult and expensive to produce polyester resins having higher and higher molecular weights utilizing standard commercial polymerization techniques.  This invention discloses a technique by which polyester resin having extremely high molecular weight can be prepared utilizing a very rapid solid state polymerization process.  This invention more specifically discloses a process for preparing ultra-high molecular weight polyester resin which comprises:  (1) dissolving a polyester prepolymer in a suitable organic solvent; (2) recovering the polyester prepolymer from the organic solvent to produce a porous, fibrous mass of the polyester prepolymer; and (3) solid state polymerizing the porous, fibrous mass at an elevated temperature to produce the ultra-high molecular weight polyester resin.

Abstract: ABSTRACT OF THE DISCLOSURE         A composite television signal is modified to inhibit the reproduction of an unauthorized recording thereof by conventional video recorders but enable the display of a video picture therefrom on a television receiver.  The length of a frame (more particularly, the length of each field in a frame) is increased or decreased from standard length, either by changing the time duration of the respective horizontal line intervals included in each frame while keeping a constant, standard (e. g. 525) number of lines per frame, or by changing the number of horizontal line intervals which constitute a frame while maintaining the standard duration of each line interval (e. g. 63.5 microseconds).  A profile pattern representing the variation of the video frame duration, or vertical period, (whether by changing the horizontal line durations or the number of lines in a frame) with respect to time is adjustable to correspondingly control the rate at which the vertical period (i. e. frame length) changes, the maximum, and minimum vertical period and the ratio of increased to decreased vertical periods.  Accordingly, substantially the same electronics responsive to the profile pattern may be used to modify the television signal; and the profile pattern itself may be changed easily, such as by simple software modifications, to accommodate different circumstances and to satisfy different conditions.

Abstract: This invention relates to feeding troughs for animals particularly, pigs. The feeding trough has an elongate trough member sub-divided by lateral partitions into individual compartments. The width of the compartments, the height of a front wall of the trough over which the animal's head extends, and acanopy which restricts the space within the compartment into which the animal's head can reach are all designed erogonomically with respect to a range of animals intended to use the trough. The base of the trough is at floor level and the front wall extends from said floor level to a predetermined minimum brisket height of a predetermined smallest size of pig intended to feed. The trough member has an inner front wall which extends angularly downwards and inwards of the trough to terminate at floor level and an inner rear wall which extends angularly downwards to terminate at a predetermined height above floor level at said mean reach. A canopy overlying the trough member and extends inwards and downwards to meet the inner rear wall at the predetermined mean neck angle of the mean weight of pig at a position equal to the maximum nose-to-crown length of the predetermined largest pig. Partitions are spaced along the trough at intervals equal to the maximum shoulder width of the largest pig. Mathematical expressions have been derived to enable the dimensions to be calculated knowing the weight of pig and the height above the floor of the feed.

Abstract: Peptidyl-glycine  alpha -amidating monooxygenase is an enzyme extractable from medullary thyroid carcinoma cell lines and tissue samples, having a molecular mass of about 60,000 to 65,000 daltons. It has been purified so as to exhibit a single, homogeneous, well-defined band using electrophoretic procedures performed on SDS-polyacrylamide gels, and has a specific enzymatic activity of at least 50 mU per mg protein. The free or immobilized enzyme, in the presence of Cu+2 ions, ascorbate, and oxygen, can be used to prepare an  alpha -amidated protein from a polypeptide substrate possessing a carboxyl-terminal glycine residue. The purified enzyme can be used as an antigen in order to produce enzyme-specific monoclonal antibodies, and can provide the information necessary to design and construct prokaryotes or other appropriate unicellular organisms or host cells isolated from multicellular organisms which possess peptidyl-glycine alpha -amidating capability.
