Abstract: The coaxial annular space between a rod and a slidably received outer cylinder is divided into three serial chambers by four seals. Two seals are spaced apart and affixed to the front of the rod. Two seals are spaced apart and affixed to the cylinder rearwardly of the first two. By relative forward rod movement, a specimen capturing zone is exposed at the desired site of a biological specimen. Thereafter, rearward rod movement reseals the capturing zone. Further, rearward rod movement reduces the volume of a media containing chamber and thereby moves the collection zone into contact with the desired medium. The third chamber prevents contamination of the biologically active portions of the structure during operation. Pre-scored break lines formed in the cylinder and rod facilitate severance of unneeded portions after collection of a biological specimen and/or after transportion to a suitable laboratory facility. Color-coded indicia are used on the rod and/or cylinder so as to facilitate proper operation. Reusable extension pieces may be attached to the cylinder and/or rod so as to adapt a standard size module to different desired end uses.

Title: Mixed refrigerant/expander process for the recovery of c_+ hydrocarbons
Inventor: ROWLES HOWARD C
IPC: C07C7/04
Filed: 1990-05-08
Granted: 1994-02-08
Abstract: ABSTRACT   The present invention is an energy efficient process for the recovery and purification of C3+ hydrocarbons from a high pressure natural gas or refinery/petrochemical feed gas containing C3+ hydrocarbons and light gases.  In the process, the high pressure feed gas is initially cooled by heat exchange with a multi-component refrigerant fluid circulating in a closed-loop cycle thereby condensing a large portion of the C3+ hydrocarbons.  The non-condensed, remaining gas is work expanded to an intermediate pressure thus providing refrigeration for condensing the remaining C3+ hydrocarbons.  The condensed C3+ hydrocarbon liquid streams are combined and are further purified by distillation in an integrated distillation column.  Optionally, refrigeration for refluxing the integrated distillation column can be provided by the mixed refrigerant cycle.

Abstract: Processes are provided for producing purified, hepatitis B surface antigen particles in mammalian cells which comprise culturing mammalian cells which produce the particles in a culture medium supplemented with a serum free of high molecular weight contaminant proteins and recovering the purified, hepatitis B surface antigen particles. Removal of molecules having a molecular weight greater than about 3 x 10 5 daltons by prefractionation, for example, allows cells to be grown in culture media containing high levels of fetal calf serum, removes high molecular weight contaminant proteins which may be inhibitory to cell growth and simplifies purification of HBsAg since high molecular weight contaminant proteins are the major contaminants removed by purification processes.

Title: Inter-cell call hand-over in radio communication systems with dynamic channel allocation
Inventor: STRAWCZYNSKI LEO
IPC: H04W36/08
Filed: 1990-12-05
Granted: 1998-06-30
Abstract: The call hand-over technique of this invention is characterized by the use of channel information from both the target base station and subscriber terminal in determining which radio traffic channel will be used to hand over a call in progress from a serving bass station to a target base station.  Calls are handed over to the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured by the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference, as measured by the target base station.  The hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both the target base station and subscriber terminal.

Abstract: A method for searching for a station carrying paging data without un-duly draining the paging receiver battery. If a station to which the receiver is presently tuned becomes unreliable, the pager scans among channels listed in a local channel list. If no paging data is received on these channels, the scan-ning among the local list channels may optionally proceed for a further inter-val at a slower rate. After it appears that paging data will not be found on channels listed in the local list, the pager begins a full spectrum search at a slaw rate until it again finds a channel carrying paging data. By this arrange-ment, battery power is expended at a rate roughly in accordance with the likeli-hood of ending a paging station.
