Patent JP-H0233998-B2 (JP)
IPC: A61B5/00
Filed: 1983-03-14
Abstract: In NMR tomography, the nuclear spins of a selected type present in a selected area of a body are selectively excited by applying first a selection gradient field and exciting thereafter the nuclear spins by a HF signal which initially effects a rotation of the nuclear spins situated in a selected plane by an angle  alpha  of less than 90 DEG , then a rotation of all selected nuclear spins by 90 DEG  and finally again a rotation of the nuclear spins contained in the selected plane by an angle of 90 DEG - alpha . As a result thereof, the nuclear spins contained in the selected area have resumed at the end of this excitation their original orientation determined by a homogeneous magnetic field, while nuclear spins located outside this area lie within a plane extending almost vertically thereto. Thereafter, a measuring gradient field may be switched on without disturbing the orientation of the nuclear spins contained in the selected area. With the measuring gradient field switched on, the nuclear spins are now excited by a 90 DEG  pulse or usual pulse sequences to produce an induction signal. The measuring processes are carried out in pairs, with the selection gradient field applied, using different excitation signals so that the nuclear spins contained in the selected area are alternately oppositely directed which means that the induction signals generated by them are phase-shifted by 180 DEG , whereas the nuclear spins situated outside the selected area are shifted in the same sense so that they supply identical signals, if any.

Abstract: The package to be wrapped is moved during a first step towards a foil section which is extended under tension transversely relative to the direction of movement of the package. During a further course of movement of the package the aforementioned foil section is applied to three sides around the package in a substantially U-shape. Subsequently, a loop is formed from the web-like foil by entraining means which act on the web-like foil. The two runs of the loop are releasably held at their ends by related holding means. These two loop runs of the foil are separated from each other using a cutting knife. The foil section thus produced, which runs along the rear side of the package, has a length which is greater than the height of the package. An end section of this foil section of greater length and which protrudes past the package is now displaced towards and against the underside of the package. A wrapping material preferably consisting of a polyvinylidene chloride foil having self-adhesive properties is used as the web-like foil.

Abstract: An infusion system capable of intravenous administration of fluid to a patient has a drop chamber (14), including a plurality of drop tubes having drop forming orifices of different preselected cross-sectional areas for forming droplets of different sizes and volumes of the same given fluid, selection means for selecting the drop tube through which the administered fluid will pass and a metering chamber (14) to allow the rate of droplet flow to be observed. The drop tube having a drop orifice capable of producing droplets of the desired size and volume appropriate for the viscosity and purpose of the fluid being administered is selected and a conventional fluid flow rate control device (20) is adjusted, while the drop rate is observed, to set the fluid flow rate. The present invention allows a change of the fluid being administered, without disassembling the apparatus or removing it from the patient by replacing the fluid reservoir, or be valving a different fluid reservoir to the drop chamber and by operating the selection means in order to select the drop tube capable of forming the size and volume droplet appropriate for the viscosity and purpose of the substituted fluid. The flow rate control device (20) may then be adjusted to set the flow rate for the substituted fluid.

Abstract: A quick termination assembly (8) for an electrical connector (11) to a flexible wire (10). The connector comprises an electrical conductive tube (14). The tube (14) has separate end opening (18) and side opening (20) to the passage (16) and a ramp (22) facing out of and extending towards the side opening (20) from the passage (16). The end opening (18) and passage (16) are adapted to receive a bare end of the wire (10) upon insertion therein, the ramp, (22) during such insertion, forcing, the bare wire (10) to bend and move along the ramp (22) out of the side opening (20) to a position extended away from the tube (14). A non-conductive sleeve (26) extends around the wire (10). The sleeve (26) as it is forced to slide along the wire (10) and tube (14) engages the extended bare wire (10) causing the bare wire (10) to bend against an exterior side of the tube (14) and pass over and encircle the bare wire (10) and tube, (14) thereby gripping and retaining the bare wire (10) and tube (14) in electrical and mechanical contact with each other.
