Title: Antenna for a Radio Communication Apparatus
Inventor: ITOH RYOH
IPC: H01Q9/36
Filed: 1994-02-25
Abstract: A miniature and high performance antenna applicable to a radio communication apparatus and made up of a straight antenna rod and an antenna coil or coil element. A first whip antenna has a first portion retractable into the casing of the apparatus and a second portion constantly positioned externally of the casing. A second whip antenna has a coil element in the form of a loading coil having a predetermined number of turns. The second whip antenna is coaxially provided on the upper end of the first whip antenna and slidable relative to and in the axial direction of the first whip antenna. The second portion of the first whip antenna is movable between a position where one end of the coil element is disengaged from one end of the second portion and a position where the former is engaged with the latter. The antenna exhibits a desirable electric characteristic when pulled out of the casing of the apparatus and, in addition, promotes the efficient use of the limited space available in the casing.

Title: Genetically engineered attenuated viruses
Inventor: PALESE PETER
IPC: C12N7/04
Filed: 1993-04-13
Abstract: The present invention relates to engineering attenuated viruses by altering a non-coding region or the coding sequence of a viral gene. Alterations of the non-coding regions which regulate transcription and/or replication are described. These alterations result in the down-regulation of the viral gene and an attenuation of the virus, either by the production of defective particles during replication, or by reducing the number of progeny virions produced during viral replication. Alterations of viral coding sequences are also described which result in a recombinant or chimeric attenuated virus.

Patent CA-2127191-A1 (CA)
Title: Artificial Stone and Method and Apparatus for Producing Same
Inventor: SHOULDICE ROBERT B
IPC: B28D1/30
Filed: 1994-06-30
Abstract: An artificial stone having a chiselled, rough-hewn look on the edges, corners and exposed faces of the product, is produced by preparing a concrete block and then fracturing it, preferably along one plane, to produce a somewhat rough face along the fracture. The fractured block is then placed into the upper end of an inclined rotating cylindrical tunnel, the tunnel having at least one and preferably two internal longitudinal ribs to initially lift the block and then produce tumbling as the tunnel rotates, the block gradually moving along the tunnel towards a lower exit end. The multiple impacts and abrasions within the tunnel produce the desired degree of additional texturing and rounding of corners and edges, to provide the desired natural aesthetic appearance.      Preferably, one or both of the angle of the tunnel and the speed of rotation are adjustable, to permit variations and optimization.

Title: Methods and therapeutic compositions for treating cystic fibrosis
Inventor: CHENG SENG H
IPC: A61K38/00
Filed: 1993-08-26
Abstract: A method for generating cystic fibrosis transmembrane conductance regulator (CFTR) function in cells containing mutant CFTR and methods for treating cystic fibrosis are described. The method for generating CFTR function in cells containing mut-ant CFTR involves contacting the cell with an agent which increases the level of mutant CFTR at cellular locations where wild-type CFTR normally functions such that the mutant CFTR generates functional ion channels or mediates ion transport at the cel-lular locations where wild-type CFTR normally functions. The methods for treating cystic fibrosis involve administering to a subject the above-described agent. Other aspects described include therapeutic compositions and packaged drugs.

Patent CA-2146381-A1 (CA)
Inventor: IKEDA SHIN
IPC: C12Q1/00
Filed: 1995-04-05
Abstract: A biosensor for quantifying a specific compound has a reaction layer containing at least an enzyme, and an electrode system having a working electrode and a counter electrode formed on an insulating base plate; the biosensor detects the specific compound contained in a sample on the basis of an electrochemical response. In quantifying, the working electrode and the counter electrode are short-circuited before the voltage is applied therebetween. The short-circuiting eliminates measuring errors that may occur due to nonuniform dissolution of the reaction layer in a sample, and achieves highly reliable quantification of a specific compound.

Patent CA-2147875-A1 (CA)
Title: Crf binding protein
Inventor: POTTER ELLEN
IPC: G01N33/566
Filed: 1993-10-25
Abstract: Corticotropin Releasing Factor-binding protein (CRF-BP) is produced recombinantly and is useful for modulating the bio-logical activity of CRF. CRF-BP or fragments thereof and/or antibodies to the proteins are employed in diagnostic assays to de-termine the levels of CRF, CRF-BP and the ratio of CRF/CRF-BP in a vascular fluid sample. Following such an assay, CRF-BP can be effectively employed to treat pregnancy-related pathological disorders by lowering the ratio of CRF/CRF-BP to within a normal range for pregnancy. The anti-CRF-BP antibodies are also useful to purify the CRF-BP and to modulate the biological effect of CRF-BPs.

Inventor: STROMER VELERE D
IPC: B30B15/00
Filed: 1994-01-26
Abstract: A hay baler (10) for producing aerated bales of hay. The baler (10) includes a packer mechanism  (26) which operates to retrieve and compress capsules (14) of hay, a plunger (16) that compresses  the precompressed capsules (14) into a bale (18) while simultaneously cutting and removing portions of the capsules (14), and includes at least one tubular cutter (28) which extends through the plunger (16) and projects a distance from the plunger face (17). The plunger (16) compresses the load (25), and plugs of hay are cut from capsules (14) and passed through the cutter (28 30). If a plurality of holes are formed, proper spacing of the holes allows the hay to breathe and permits shipment of bales (18) of hay without fear of premature spoiling. A single continuous  cut hole may be formed in the bale to provide aeration. The tubular cutter (28) may be located in a position other that the baler plunger to form a continuous hole through a completed  bale of hay.

Title: System and method for indicating the position of a surgical probe
Inventor: BUCHOLZ RICHARD D
IPC: A61B19/00
Filed: 1994-04-25
Abstract: This is a system for determining a position of a probe (302) relative to as object such as a head of a body of a patient. The head includes a surface such as a forehead having a contour. Cross-sectional images of the head are scanned and stored as a function of the forehead contour. If the forehead contour does not appear in the scan images, then the position of the forehead contour relative to the scan images is determined with an optical scanner (380) and ring (590). During surgery, the optical scanner (380) also determines the position of the tip of the forehead relative to the ring (590). An easy (300) for receiving radiation emitted from the probe and from the ring generates signals indicating the position of the tip (301) of the probe (302) relative to the ring (590). A stereo-tactic imaging system (324) generates and displays an image of the head corresponding to the measured position of the tip (301) of the probe (302).
