Inventor: JENSEN OLE H
IPC: H03G3/20
Filed: 1989-09-27
Granted: 1993-05-11
Abstract: ABSTRACT       Power Amplifier for a Radio Frequency Signal A power amplifier is provided for amplifying, a radio frequency signal such as in a burst modulation manner for use in GSM cellular radio The amplifier has means, such as a ROM (16), for producing a predetermined sequence of values in response to a control pulse. Means (21) are provided for converting each value into a power control signal, and control means (9) are provided for controlling the amplifier output power in accordance with said power control signal. In this manner, the power/time characteristic can be made to take the form of a raised cosine. The invention also provides power selection means for selecting a nominal output level from a plurality of discrete levels and for selecting power sub-levels offset from said selected level. An indication is recorded as to which sub-level best represents the nominal power level.

Title: System for selective cell separation from cell concentrate
Inventor: HARDWICK R ALAN
IPC: A61K35/14
Filed: 1989-09-28
Granted: 1995-04-11
Abstract: A system for the selective separation of a specific cel population  from  a  heterogeneous  cell  mixture  is  disclosed herein.   Means  are  provided  for  obtaining  a  selective  cell concentrate from the heterogeneous  cell  mixture by separating the  selective  cell  concentrate  based  upon  the  physical  or biological properties of the concentrate.  This may be done by centrifugation,  if  desired.   A  container  is  provided  having particle means, the particle means being attached to a substance that  is  active for binding to a specific desired  cell.   One brings the cell concentrate into contact with the particle means within   the  container,  for  example,  by  providing  sterile connection between the site where the cell concentrate is formed and  the  container.   This  permits  incubation  of  the  cell concentrate with the particle means, to thereby selectively bind a  specific  cell  population from the cell  concentrate to the particle means,  creating a particle/cell  conjugate.   Magnetic means  are  then  provided  for  separating  the  particle/cell conjugate  from  the  remainder  of  the  cell  concentrate.   A two-magnet system may be used to form the separation.

Abstract: ABSTRACT OF THE DISCLOSURE A rotor assembly for permanent magnet motors or dynamoelectric machines in general includes a set of laminations forming a rotor body, each lamination having a plurality of V-shaped slots therein.  The laminations are rotationally skewed with respect to one another.  A rotor shaft is longitudinal to the rotor body.  A generally rectangular permanent magnet is disposed in each leg of the V-shaped slots, the slots of each lamination being shaped so as to receive the rectangular permanent magnet through all the skewed laminations with a minimum air gap.  Each slot is generally wider at each end of each leg and tapers to a waist near the midpoint of the leg.

Abstract: A child resistant closure for bottles is provided that permit closure withdrawal by exerting an axial force and a simultaneous rotating movement. For this purpose, a clutch is provided between an inner cap and an outer cap of the closure with at least one elastic flexible clutch element which is ineffective in its rest position and which is deformable upon application of an axial downward force. In this manner, a sufficient friction lock is generated between the two caps, so that the outer cap takes along the inner cap during screwing on and unscrewing off. In the absence of the axial force the outer cap will slide over and not turn the inner cap.

Abstract: A fluid-pressure-operable device 1 includes two relatively-movable components 2, 3 defining a variable-volume working chamber 9. A sealing element 5 of elastomeric material is carried, or formed, by one of the components and is in sliding and sealing engagement with the other of the components normally to resist escape of fluid under pressure from chamber 9 to the exterior thereof. That face 15 of element 5 remote from the chamber is so provided with channel 16 that as pressure in the chamber increases the element is permitted progressively to deform and some of the material of the element thus displaced is then accommodated by the channel. When the pressure exceeds a predetermined value, deformation of the element is such that sealing engagement of the element with the other of said components is broken so that the pressure in chamber 9 is relieved to the exterior thereof.

Such shattering will provide a clear indication that penetration of the pro-tective layer has occurred.  Also there may be provided an associated dye which will exhibit a color change when the outer protective layer is shattered.  A warning message may be provided on said packaging underlying the outer layer.          Use of the brittle material in a blister package is contemplated with or without an underlying packaging layer and other uses of the brittle material without support are contemplated.
