Title: Tmb formulation for soluble and precipitable hrp-elisa
Inventor: WOISZWILLO JAMES E
IPC: G01N33/535
Filed: 1990-11-02
Abstract: ABSTRACT    Solvent systems for use in increasing the solubility of 3,3',5',5'-tetramethylbenzidine  (TMB) and  for  making  a permanent color record of the results of ELISAs using HRP have been developed.   In the improved solvent system containing povidone,  1-ethenyl-2-pyrrolidinone  polymers,  TMB  can be dissolved in a very small quantity of solvent,  up to a concentration of 100 to 200 mM, which can then be mixed directly into an aqueous buffer without precipating the TMB.          In the solvent system for making a permanent record, alginic acid  (AA),  methyl vinyl ether/maleic  anhydride copolymer (MVE/MAC), dextran sulfate (DS) and/or carrageenan are added to the aqueous buffer solution, with or without povidone, to form a colored precipate with the reaction product.

Inventor: LUCH DANIEL
IPC: B65D77/20
Filed: 1991-07-25
Abstract: ABSTRACT      A tamper-evident, snap-on, screw-off closure is used with a specially shaped container neck.  The neck has double lead external threads and, below the threads, external ratchet teeth arranged in two diametrically opposed quadrants.   The closure has an upper skirt having internal threads mating with the neck threads. A lower skirt is connected to the upper skirt by a plurality of frangible bridges.  The lower skirt has opposed quadrants having internal ratchet teeth to mate with the neck ratchet teeth. The lower skirt has a tear tab which, when pulled, fractures the lower skirt on a vertical line. Continued pulling on the tab sequential-ly fractures the bridges.  The tear tab constitutes an orientation means to properly locate the cap on the neck so that an axial downward push on the cap engages the internal and external threads and internal and external ratchet teeth.

Abstract: ABSTRACT         This invention relates to benzoporphyrin containing vesicles which are suitable for pharmaceutical application.,  In particular, the present invention relates to a liposomal prepara-tion of benzoporphyrin (BPD) incorporated into vesicles compris-ing a liposome forming lipid such as EPC or DMPC at a drug to lipid ratio of greater than 100 ug/umole lipid which will allow adequate drug dosing with relatively low lipid concentration.  In an additional aspect of the present invention, sized liposomes are described which are storage stable.  Certain sized BPD-containing vesicles (no greater than about 120 nm in diameter) permit sterilization by terminal filtration.  Further, a lyophil-ized preparation of the BPD lipid mixture can be obtained from aqueous buffer under conditions which do not result in vesicle fusion/aggregation or BPD precipitation.         Liposomes according to the present invention are able to accommodate surprisingly large amounts of BPD within the bilayer of the liposome, rather than in the encapsulated buffer.  The advantages of this surprising aspect of the present invention includes the ease of manufacture and the cost savings associated with an efficient use of BPD are also presented.

Title: Road vehicle having a rear dump box
Inventor: FRIESEN LEROY
IPC: B60P1/28
Filed: 1991-12-31
Abstract: ABSTRACT OF THE DISCLOSURE             The structural design of a truck box is improved for mounting on a conventional chassis,  the truck box being of the type which is pivotal about a transverse axis at the rear end of  the  truck box  for  lifting of the forward end of the truck box by a jack for discharge of pourable solid materials through a rear tail  gate.     The structure of the truck box includes a pair of longitudinal I-beams under the floor with the  I-beams  designed  to  constitute  the  main  longitudinal support  for the truck box.   The floor can thus simply be a sheet laid across the top of the I-beam without the necessity for  transverse  structural  ribs.    Sidewalls  also include no vertical structural ribs but include a fabricated longitudinal box section along the top edge to prevent outward bowing of the side  walls.    The  longitudinal  force  on  the  truck  box  is transmitted to the jack by a pair of beams welded to the top of the I-beams and extending upwardly and forwardly therefrom to a cradle at the top of the front wall attached to the top of the jack.     The  structural  design  uses  less  material  than conventional arrangements and is improved aerodynamically.

Patent CA-2079192-A1 (CA)
Inventor: STRONG BERNARD
IPC: A61B5/15
Filed: 1992-09-25
Abstract: A combined lancet and multi-function cap of the disposable type, for use in obtaining blood samples for diagnostic purposes. It comprises a lancet including a needle with a sharp end, and an elongated body of plastic material embedding the needle except for its sharp end. It also comprises a multi-function cap also made of plastic material, which is detachably mounted onto one end of the body to embed the sharp end and keep it sterile until the lancet is used. The multi-function cap includes a ring having a central opening sized to let pass the sharp end of the needle but not the body of the lancet. The multi-function cap also includes a set of legs or a skirt that project from the ring and are useful for connecting the same to a lancet injector having a mouth through which the lancetmay be inserted and suhsequently projected out to penetrate the skin of a patient. Thus, the cap also serves as an isolation barrier between the patient's finger and the physical lancet injector. In use, when the multi-function cap is detached from the lancet and is connected to the lancet injector, the ring of the cap extends across the mouth and positively controls the depth of penetration of the lancet in the patient's skin. This ring also serves to lock the needle within the cap after use and thus reduces the danger of accidental finger-stick by a blood contaminated needle. Also disclosed is a lancet injector for use with the above lancet and multi-function cap, which is so devised as to eject the lancet after use, together with the cap that firmly grips onto the lancet to act as a protective locking hood for the needle. This lancet injector preferably incorporates an elastomeric band to project the lancet upon firing, instead of a metallic coil or leaf spring.
