Title: Means for fluid administration
Inventor: CLARKE ELLIS W
IPC: A61M5/14
Filed: 1987-03-19
Granted: 1991-07-16
Abstract: ABSTRACT   An administration set which is suitable for giving an infusion of liquid to a patient by gravity flow from a container of liquid through the set and to the patient is described.  The administration set comprises a fluid reservoir, a flow regulator and a barostat device which compensates for changes in fluid pressure during the infusion.  The fluid reservoir is positioned upstream of the flow regulator and the barostat device is downstream of the flow regulator.  In a preferred embodiment a piercing needle connects with a closable tube and injection site which enter the main body of the reservoir by a secure seal.  One side of the top of the reservoir extends in a curving manner to be in front of the closable tube and joins an air channel that leads to an airtight chamber which holds the barostat device.  An outlet passage leads from the bottom of the reservoir to a collapsible region and descends to an outlet tube which leads via the regulator to the barostat device.  A resistive pathway is formed between the ascending and descending parts of the outlet passageway whereby the reservoir may empty slowly when the collapsible region is collapsed. A drip-chamber may be placed in the infusion tube.  A collapsible tube is placed downstream of the barostat device.

Title: Structure of a flat-type brushless dc motor
Inventor: SAOTOME TOSHIO
IPC: H02K7/08
Filed: 1988-03-10
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE         A flat type DC motor applicable for disc drive of an electronic still camera in which vibrations of the rotor axle are prevented without increasing manufacturing costs by providing the magnetic field between the stator and rotor to be asymmetrical so that the magnetic attracting force of the rotor to the stator is also asymmetrical.  The asymmetrical attracting force causes the axle of the rotor to be urged in the same radial direction relative to the axle bearing in the stator, thus, movements of the axle in radial directions in the clearance between the axle and bearing of the stator are eliminated and the rotor rotates without vibrating.

Abstract: ABSTRACT OF THE DISCLOSURE         An acidic  molasses-based liquid animal feed supplement stock including calcium and magnesium at a calcium to magnesium weight ratio between about 1.5 and 3, and, optionally, non-protein nitrogen, is hardened into a solid form by the addition of a phosphorous-containing compound in a nutritionally appropriate amount.  The solid animal feed supplement is sufficiently palatable to permit its free choice feeding, yet discourages overfeeding by its hardness and acidity.  The solid feed supple-ment contains sufficient molasses to help meet the energy requirements for maintenance and weight gain of grazing animals, but is sufficiently low in pH to minimize the risk of ammonia poisoning due to breakdown of non-protein nitrogen sources to free ammonia during rumination.  Also disclosed is a method for storing a solidifiable molasses-containing animal feed supplement by employing two separate solutions, one containing phosphorous and the other containing molasses, calcium and magnesium.          Further disclosed is an aqueous sugar-containing solution.

Granted: 1993-05-25
Abstract: ABSTRACT      An apparatus for continuously feeding the individual elements from tiered loads has a hoist, including both vertical and horizontal support members, which can both be pivoted back to come in contact with an accumulator arm assembly by the motion of a rotatable support base, thereby allowing the load to be raised upwards along an angular load path.  The accumulator arm assembly includes a carriage assembly which can slide part of the way down the load path, and independently extendable accumulator arms for extending  beneath  the  bottom  of  the  tiered  load  once approximately one-half of the load has been unloaded down the load-discharging members to the fixed and predeterminable load discharging point, where it can be processed on a conventional feed table.   After the accumulator arms have been extended and have begun to raise the remainder of the load along the last portion of the load path,  the hoist is free to return to its initial position and accept a second load of material.   In an alternate embodiment the hoist is omitted, thereby providing an accumulator arm assembly which can be retrofitted into, and used in conjunction with, existing hoists.

Abstract: SULFOAMINO DERIVATIVES OF CHONDROITIN SULFATES,  OF DERMATAN SULFATE  AND          OF HYALURONIC ACID AND THEIR PHARMACOLOGICAL PROPERTIES.                               ABSTRACT Novel derivatives are  disclosed as  obtained from  chondroitin  sulfate, dermatan sulfate  and  hyaluronic  acid, having  a  molar  ratio  between sulfate groups and carboxylic groups like that of heparin and furthermore characterized by possessing, as the heparin, the sulfoamino group at  the carbon atom at the 6 position of hexosamine. The  novel  compounds  show  a  very  remarkable  clearing  activity   in comparison with  the starting  mucopolysaccharides, this  activity  being similar and for some derivatives comparable with that of heparin. Moreover, differently  from  what normally  happens  upon  sulfating  the sulfomucopolysaccharides,  the  anticoagulating activity  of  the  novel compounds is negligible or anyhow very reduced. The compounds  of the  present  invention  find use  in  the  therapy  of arteriosclerosis.

Abstract: An incontinence device comprising a generally tubular soft latex shape (20) open at both ends. The upper end (24) is smoothly curved and tapered inward (28) to the opening (26) with the latex of minimal thickness and coated on the outside adjacent the opening (26) with a suitable adhesive for contact with the skin about the anal opening. The lower end (22) is partially folded and clipped to permit the device to be affixed with an applicator (30) specifically shaped (32) for the purpose and inserted within the device. The shape and material of the device permits the device to fully stretch and shrink with the anal opening while remaining adhesively affixed to the skin. An extended polyvinyl chloride/urethane mixture of similar elasticity, flexibility and elongation may be substituted for the latex. Because of the very thin wall thickness, the device may be formed as a flat hollow body (120) which expands in use. The applicator (430) may be permanently attached to the device and formed to serve as a vent (433) for liquids as further alternative constructions.

Title: Method for the transmission of data between two stations by means of optical waveguides
Inventor: BRAHMS MARTIN
IPC: H04B10/556
Filed: 1989-06-01
Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE     In a system wherein a main channel of data is transmitted between two stations by means of an optical waveguide, an additional optical channel may be transmitted.  Bits of the additional optical channel are inserted into the main channel at a transcoder in the transmitting station in place of bits of the main channel at defined spacings, known to the transcoder of the receiving station, with a bit rate lower than that of the main channel.  The inserted bits are removed from the optical main channel at the receiving station.  The bits of the additional optical channel inserted into the main channel are double bits that are identical to a forbidden bit combination that results during the recoding of an electrical AMI code into an optical CMI code.  In the receiving station, the double bits of the main channel replaced by the bits of the additional optical channel are recovered by using sequential logic and memory to apply the fixed rules of the electrical AMI code.

Granted: 1994-11-29
Abstract: A method for automatically calibrating a controller for a valve controlled system follows consistent procedures to make precise adjustments to valve characteristics.  The controller is placed in a calibration mode, then the valve settings are modified over a full range of operation.  At predetermined levels of operation, the valve settings are maintained at preset values while system performance is measured.  After the full range of valve operation has been covered, adjustments are made to the correspondence between the valve settings and the levels of operation in dependence upon the differences between the measured system performance and the predetermined levels of operation.  This procedure is repeated to provide average values and also to make changes to valve characteristic curves corresponding to different modes of operation such as single valve and sequential valve modes.  Other control parameters may be adjusted by evaluating system performance during normal operation.
