IPC: B21D43/09
Filed: 1988-10-18
Abstract: An apparatus for the correct feeding of continuous strips (11) with a shaped side outline to blanking or pressing machines, such as presses, by means of which the continuous strip, unwinding from a roll, can be feed in a position of perfect trueing under the die of the blanking machine, thanks to the presence of a control and of a continuous correction of the positioning errors caused by stresses, or a non-perfect axiality in the fed strip. The strip (11) is fed by a pair of rolls (24,27) one being motor-driven and operatively connected to sensor elements (23) detecting the change in the shaped side outline of the strip.

Abstract: A method for separating liquids, particularly hydrocarbons from water, whereby a small amount of a high molecular weight polymer is dissolved in the hydrocarbon to render it viscoelastic. A hydrocarbon layer is then mechanically removed from the water in a manner which causes rapid stretching of the hydrocarbon with attendant development of elastic properties in the hydrocarbon layer. The polymer may be applied to the surface of the hydrocarbon as droplets of a relatively concentrated polymer solution or as solid particulates having a polymer core covered by a powdered solid material which is non-reactive toward the polymer.

Abstract: An integrated records management system having the capability to record and transcribe dictation. The system is particularly useful for the prompt and efficient management of patient's medical records. The system includes a digital dictation sub-system with a number of dictation input units and a number of transcription output units. The dictation system receives dictation jobs corresponding to reports, and particularly medical reports and stores them as voice files for later output for review of transcription. Job records containing information about the dictation jobs is transmitted to a database server which manages and maintains a database of medical records. The transcription output terminals together with word processing stations connected to the database server form work stations for transcriptionists. When a dictation job is to be transcribed, the database manager combines information in the database with a selected form for the identified report type prior to transcription and when the dictation job is transcribed into that format to form a complete document representing a report, selected portions of that report may be extracted to form a summary report by the system database manager. The system also includes printers for output of reports, a system administrator station, a communications link to other data processing systems, and archival storage.

Granted: 1995-12-19
Abstract: A limit stop/latching assembly in a disk storage system includes a crash stop for limiting travel of the actuator carriage at a fixed stop position.  The assembly has a carriage latch incorporated with the crash stop.  A magnetic latch actuator plate extends from the actuator carriage and is movable with the actuator carriage in a path of travel of the actuator carriage to abut the stop position.  The carriage latch has a magnet and a pair of magnetic pole pieces abutting the magnet wherein the distance between the pole pieces defines a fist gap and the distance between the pole pieces and the latch actuator plate defines a second gap.  The latch is moved between a latched position, wherein said pole pieces are in magnetic contact with the latch plate, and a free position, wherein the actuator carriage is pivoted such that the second gap is greater than the first gap whereby magnetic flux is channeled substantially through the first gap to enable the latch plate to move remote from the crash stop.

Granted: 2000-06-20
Abstract: A positive displacement flowmeter comprising a flowmeter portion including a pair of rotors rotatable in proportion to a fluid's flow in a measuring chamber and a counting portion for measuring a total flow by counting the rotor's rotations. It has many improvements. Firstly, the flowmeter is protected against the penetration of rain water into its counting portion. Furthermore, the counting portion housing is so constructed as to assure the easy mounting of an electric circuit and like components therein and also the possibility to control said circuit from the outside of the housing by use of reed switches and the like.      The flowmeter is improved not to transfer heat of a fluid of high temperature to the counting portion and, furthermore, to assure the easy mounting of rotors in the measuring chamber. Particularly, it is possible to provide high performance rotors mounted in the measuring chamber by using non-circular gears having a special tooth profile and made of special materials. Other various improvements are presented.

Title: Catheter assemblies for prevention of blood leakage
Inventor: HOLDAWAY RICHARD GARY
IPC: A61M39/00
Filed: 1990-12-14
Granted: 2002-01-15
Abstract: A catheter is provided which deters the backflow of blood between the insertion needle and the catheter cannula by forming the distal end of the catheter hub so as to restrict the inner diameter of the catheter cannula to a wiping fit with the engaged insertion needle. In a first embodiment the distal end of the catheter hub is pre-formed to its desired final inner dimension. The distal end of the hub is stretched to an oversize condition, the catheter cannula is attached to the hub, and the distal end of the catheter hub is heated, causing a stress relief of the previously stretched hub. The distal end of the catheter hub returns to its pre-formed dimension which will mechanically restrict the diameter of the catheter cannula at that point to form the wiping fit with the engaged needle. In a second embodiment the inner diameter of the distal end of the catheter hub is reduced by inserting the distal end of the hub between the opposing faces of a swaging press. which close to compress the hub in one direction. The degree of closure is controlled by the dimension of at least one of a pair of orthogonally opposing swaging press surfaces, which then close to compress the hub in the orthogonal direction. The distal end of the hub is thus swaged to the desired dimension, and the process advantageously produces a finished product without the production of flash material at the intersection points of the swaging surfaces.
