A safety-shielded trocar having an obturator with a linear cutting edge surface defining a base width substantially less than the diameter of the safety shield is disclosed. When the trocar is inserted through tissue, the tissue dila tes from the width of the linear incision to accommodate the size of the safety shie ld of the trocar, thus making it possible to provide an access opening greater th...

A process for making cheese including: a) adding to cheesemilk a transglutaminase, incubating for a suitable period, b) incubating with a rennet so as to cause clotting, and c) separating whey from the coagulate, and d) processing the coagulate into cheese. Cheese products produced by said process are contemplated and to the use of transglutaminase for maintaining proteins in the cheese material d...

A flashlight (10) has a switch housing in between the battery compartment and reflector. The neck of the switch housing holds a lamp support (58) at a central position within a reflector. An O-ring on the rear of the switch housing seals the battery compartment. The switch housing partially floats within the flashlight tube (12) to allow for a slight adjustment of the lamp (60) relative to the ref...

This innovation relates to a rotating mat for switching equipment, fitted with o ne or more holding flaps and means capable of exerting a recalling force on said mat w hen the flaps are on the transmission rollers, characterized by the fact of providin g, to apply said recalling force, some flexible elements attached to the mat's surface at the anchoring of point said flaps.

A device is described for actuating the unloading mat in switching machines of a type comprising means capable of engaging a supporting roller for the said mat, so as to control its rotation and effect the unloading of the transported object during t he forward motion of the trolley holding said mat. Said means include a rack capable of engaging a sprocket solidly affixed to the shaft of one of th...

A single-bed PSA system comprising a blower, an adsorber vessel, and a gas product storage tank separates a gas mixture using a three-step cycle comprising adsorption, evacuation, and pressurization. Pressurization is accomplished by introducing gas from the gas product storage tank into both the feed end and the product end of the adsorber vessel. Preferably a portion of the pressurization gas is...

The invention relates to an optical add/drop device comprising at least two optical filter units (OADE). An individual filter unit comprises a first, second and third port so that when all signals of the aggregate signal are present at the first port (A), said desired signal is present at the second port (B) and all other signals except the desired signal are present at the third port (C). To prov...

The invention relates to packet-switched transmission of calls and particularly to real-time packet-switched transmission of speech calls. The object of the invention is to provide a method that allows efficient use of the transmission capacity without impairing the quality of real-time calls: information can here be transmitted by a packet-switched method so that the transmission delays remain sh...

The invention relates to a method, a network node and a data transmission system for packet-switched data transmission in a data transmission network that comprises at least two network nodes (DXT, BS) for receiving and transmitting packets. The packets (3, 4, 5, 6) sent from the first node (DXT) to the second node (BS) are packets whose destination address indicates the second node as the next no...

A test strip incubation device and method for developing a test strip having a reagent test pad disposed thereon, the reagent test pad requiring an incubat ion time, which allows greater accuracy and reliability of test results as well as a n arrower window of PASS and FAIL indication concentrations. The device comprises a te st strip holder which allows a wetted reagent test pad to be vertically...

A machine and motor oil drip guard comprising a core of oleophilic and hydrophobic sorbent material is disclosed, the drip guard being attachable directly to the location of a point of leakage or dripping of lubrication, hydraulic or processing liquids from machinery.

A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a paris...

An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the perform ance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfaci ng surface applying pressure in a predetermined range wherein one of t...
