Title: Inductively coupled plasma spectroscopy
Inventor: TURNER IAN L
IPC: H01J49/10
Filed: 1991-07-23
Abstract: In inductively coupled plasma spectroscopy. the use of an induction coil assembly comprising at least two helical coils which are arranged in overlapping relationship. In one practical form, the overlap is achieved by interlacing of the coils so that at least one turn of one coil is interposed between two adjacent turns of the other coil. For that purpose, the two coils will ideally be of the same diameter and will be coaxial. A tubular part of a plasma torch is contained within the space surrounded by the coil assembly, and a RF energy source is connected to an end of each coil.      The other ends of the coils may be connected to ground.

Title: Exercise apparatus
Inventor: POTTS WILLIAM W
IPC: A63B21/00
Filed: 1991-07-29
Abstract: EXERCISE APPARATUS Abstract of the Disclosure An exercise apparatus having foot beams (38"', 40"') rotatably mounted to an upright post member (140"') of a frame (138"').  Mounting blocks (242) are rotatably mounted to the upright post member above the foot beams to rotate about a first axis (248), and are linked by tie rods (136"') to the foot beams. Hand levers (132"' and 134"') are mounted to the mounting blocks by elastomeric torsion springs (256). Downward rotation of a foot beam results in rotation of the corresponding linked mounting block and hand lever about the first axis. Differential force exerted on the hand lever relative to the foot beam results in rotation of the hand lever about a second axis (284) and storage of energy by the elastomeric torsion spring. The hand lever is urged back to its nominal position by release of the stored energy.

Title: Flashback plug
Inventor: PETERSON GERALD H
IPC: A61M25/06
Filed: 1991-11-22
Abstract: A  flashback  plug  has   a   body  molded   of   a semi-translucent  polymeric  material  along  and  about  an axis.   A distal end of the body engages in fluid tight communication a needle hub flash chamber and a proximal end extends therefrom to  receive  a  fitting.   A passage extends through the body along the axis from the proximal end to the distal end to permit flow therethrough.  A vent membrane of a hydrophobic filter media is mounted by its periphery across the passage.  The vent membrane is insert molded within the body to capture the proximally extending periphery thereof so that liquid in the passage distal end can not reach the proximal end.  The proximal end of the passage  has the  shape  of  a  female  luer  taper  which terminates distally with at the vent membrane. A pair of opposed channels extend longitudinally and parallel to the axis  from the vent membranes to the proximal end.   The distal end of the body has an outside a male  luer  for engaging the needle hub flash chamber.

IPC: H04Q1/54
Filed: 1991-12-19
Abstract: A method is used to switch a channel which is used for a communication between a transmitting end and a receiving end from a main channel to a protection channel . The transmitting end includes N first bipolar switches respectively having an input port for receiving a baseband signal input, a main port for outputting the baseband signal input to a corresponding one of N main channels and a protection port for outputting the baseband signal input to the protection channel. The receiving end includes N second bipolar switches respectively having a main port for receiving the baseband signal input received from the transmitting end via a corresponding one of the N main channels, a protection port for receiving the baseband signal input received from the transmitting end via the protection channel and an output port for outputting the received baseband signal input as a baseband signal output. A loss of the received baseband signal input when the protection channel is used is dependent on an arbitrary number of second bipolar switches through which the received baseband signal input passes before the baseband signal output is obtained. The method comprises the steps of (a) recognizing at the receiving end the main channel from which the channel is switched to the protection channel, (b) generating at the receiving end control information related to an amplification of the baseband signal input received via the protection channel based on the main channel recognized in the step (a), and (c) amplifying at the receiving end the baseband signal input received via the protection channel by the amplification determined by the control information generated by the step (b).

Title: Method of removing ions
Inventor: LOMASNEY HENRY L
IPC: C02F1/469
Filed: 1990-07-20
Abstract: Remediation of soil and groundwater-bearing aquifers by the use of an ion immobilizing matrix introduced into a bulk liquid or soil either as a membrane covering or as a canister or similar suitable configuration. The ion immobilizing or host receptor matrix is associated with, and may envelop, at least one electrode. An oppositely charged electrode is located at a distance from the enveloped electrode, with the contaminated bulk therebetween. An electropotential is established which causes the ionic species to migrate through the water or soil and ultimately to become immobilized in the host receptor matrix. Once the host receptor matrix is fully loaded, it can be withdrawn and disposed of as a solid waste form. In one configuration, the electrode is imbedded within the host receptor matrix. In another configuration, the electrode is positioned inside an ion reservoir confinement chamber which has as one surface an ion permeable membrane optionally in contact with an immobilizing ion exchange polymer. The host receptor matrix can be an ion-conductive organic polymer membrane composite which may incorporate ion exchange media or selective absorbent materials as fillers, or optionally a medium that can facilitate both ion transmission and complexation which can insolubilize the mobile ionic media thereby yielding a stable repository for the ions being captured. This apparatus and method provides a solid wasteform which can be easily and safely removed for disposal and which is practical for volume reduction by incineration.  Alternatively, a host receptor matrix is provided which permits rapid discharge of ions from the matrix when the electropotential is reversed.
