Abstract: A tunnel freezer (1) comprises an elongate tunnel (2) which is inclined to the horizontal and which can be rotated about its longitudinal axis (X-X). The inside of the tunnel (2) is provided with a weir (6) which retains a pool (7) of liquid nitrogen between the weir (6) and the upper end (5) of the tunnel (2). Particles (12) to be frozen are introduced into the tunnel (2) on a conveyor (8) and drop into the pool (7) where they freeze substantially without aggregation. Rotation of the tunnel (2) carries the particles out of the liquid nitrogen and through the remainder of the tunnel (2) to the outlet end (13) of the tunnel (2). The frozen particles and the nitrogen vapour from the tunnel (2) pass through a common outlet (15) which is provided with a pivoting plate (16) which restricts the flow through the common outlet (15) so that the tunnel (2) operates at or slightly above atmospheric pressure thereby inhibiting ingress of moist air into the tunnel (2). Movement of particles through the tunnel (2) is facilitated by lifting bars (27, 28, 29, 30) which form part of a liner (33) which can be readily removed and replaced as desired. In a second embodiment the tunnel (2') is provided with a spiral ribbon (6') which forms a multiplicity of pools (7') extending along the tunnel (2'). This embodiment is particularly useful where the supply of frozen particles is variable.

Abstract: A dual status marker for use in electronic article surveillance systems having an alternating magnetic field, comprises a magnetic responder element having at least one central switching portion (12, 30, 32, 34, 36) and flux collectors (14, 16, 38, 40, 42, 44) on each end thereof which concentrate flux within the switching portion to ensure that the flux density therein is sufficient to generate an appropriate response. The marker is made dual status by providing magnetizable keeper elements (18, 20, 46, 48, 50, 52) adjacent the flux collectors. When the keeper elements are magnetized, the associated field biases the flux collectors and inhibits magnetization reversal therein in response to an interrogation field, thereby preventing flux from the interrogation field from being concentrated in the switching portion of the responder element.

Abstract: Biological fluid test samples are analyzed for a broad spectrum of drugs, including benzodiazepines, amphetamines, tricyclic antidepressants and opiates, in a single isocratic analysis using a chromatographic column system containing three analytical columns -- an anion exchange column, a reversed phase column and a cation exchange column. A pre-column is also included to purge the sample of salts, proteins, peptides and hydrophilic anions. Carrier liquids containing aceto­nitrile at various strengths are used for distribution of the various drugs among the columns, elution of the drugs from the columns, and column purging and condition­ing. The system readily lends itself to automation, automatic periodic sampling, and component identification and quantification.

Abstract: A dielectric filter is formed from a block (10) of ceramic material with holes (16, 17, 18, 19) extending from a top surface (11) toward a bottom surface (12). At least the bottom (12), both ends (13) and one side surface (14) are coated with conductive material. Also, the interior surfaces of the holes (16, 17, 18, 19) are coated with conductive material to form transmission line resonators.

Title: Electrophoresis apparatus
Inventor: GORDON GARY BABCOCK
IPC: G01N27/447
Filed: 1990-06-29
Abstract: An electrophoresis capillary with dispersion-inhibiting cross-section for providing unprecedented levels of detec­tion sensitivity of solutes in a separation collumn is disclosed. The higher level of sensitivity is accomplished by utilizing larger sample volumes contained in capillaries having non-circular cross-sections. The present invention avoids the unwanted turbulence, viscosity gradients, and gravity siphoning that plague previous conventional devices that employ circular capillaries having equivalent cross-­sectional areas. The key to the enhanced performance that is achieved using the present invention is a novel non-­circular capillary (32) which has a cross-sectional confi­guration that maximizes the central area of the capillary without creating the conditions that cause uneven flow through the capillary. The capillary (32) has a generally oblong cross-section. An exterior surface (46) encloses a capillary wall which defines two generally radial channels (35) that extend in opposite directions from the center of the capillary along its transverse axis. The maximum width dimension (37) of each channel is approximately fifty mi­crons. The ratio of the length and width of the channels is generally equal to two or greater. The present invention combines the selectivity of a conventional, smaller, round capillary with the sensitivity of a capillary which is ten times larger.
