Title: Oligonucleotide tags for sorting and identification
Inventor: ALBRECHT GLENN
IPC: C12Q1/68
Filed: 1996-06-06
Abstract: The invention provides a method of tracking, identifying and/or sorting classes or subpopulation of molecules by the use of oligonucleotide tags. Oligonucleotide tags of the invention comprise oligonucleotides selected from a minimally cross-hybridizing set. Preferably, such oligonucleotides each consist of a plurality of subunits 3 to 9 nucleotides in length. A subunit of a minimally cross-hybridizing set forms a duplex or triplex having two or more mismatches with the complement of any other subunit of the same set. The number of oligonucleotide tags available in a particular embodiment depends on the number of subunits per tag and on the length of the subunit. An important aspect of the invention is the use of the oligonucleotide tags for sorting polynucleotides by specifically hybridizing tags attached to the polynucleotides to their complements on solid phase supports. This embodiment provides a readily automated system for manipulating and sorting polynucleotides, particularly useful in large-scale parallel operations, such as large-scale DNA sequencing, mRNA fingerprinting, and the like, wherein many target polynucleotides or many segments of a single target polynucleotide are sequenced simultaneously.

Patent CA-2226539-A1 (CA)
Inventor: COLLMANN RALF
IPC: H04B17/391
Filed: 1998-02-13
Abstract: For determining the spatial distribution of the traffic volume within a radio cell of a cellular mobile radio communications network, a test signal transmitter is usually installed at a test location. Each mobile station which receives the test signal, measures and reports the receives level to a computer for evaluating the test location. The test location is deemed to be suitably for the installation of a new base station if the majority of the mobile stations receives a test signal of sufficient strength.  In order to provide a simple method for determining the spatial distribution, it is proposed to first subdivide the radio cell (RC1) into several segments (A1, A2, A3, ... , D4) and to associated respective reference values (e.g. reference receive levels) with these segments.  The reference value are calculated with the help of a Radio Communications Network Planning Tool, wherein the distances from the segment (C2) to at least two of the base stations (BS1, BS2) can be derived from the reference values. Subsequently, measured values (e.g. the actual receive level) which depend on the length of the radio transmission paths, are determined for each mobile station (MS). After the reference values are compared with the actual values, the respective segment (C2) in which the mobile station (MS) is currently located, is marked. A counter setting indicating the traffic volume in this segment (C2) is then incremented for this segment (C2). A test signal transmitter is not required.

Title: Apparatus and process for casting large concrete boxes
Inventor: GORDON HARRY
IPC: B28B1/32
Filed: 1998-01-20
Abstract: A method of forming concrete integral box shaped modules provides dimensional accuracy and sustains closer tolerances thus permitting surfaces of adjacent modules to match. The method utilizes a standard fixed box frame with vertical walls that can be easily reset after forming a module. The method includes the steps of constructing a fixed box form with four vertical rectangular sides and a top horizontal surface, top trays extending out from top edges of the rectangular sides and bottom trays extending out from bottom edges. Corner fillers are placed in vertical corner spaces formed by the four vertical sides, steel mesh and rebar is laid on the vertical sides and in the trays, the trays are then filled with concrete and concrete is sprayed onto the vertical sides. The module is steamed to set the concrete, the trays are removed and the module is raised initially by jacking to release the module from the box form.

Title: Steerable rotary device
Inventor: MARTIN MERRILL DAVID
IPC: B65G39/16
Filed: 1998-01-28
Abstract: A steerable rotatable member such as a pulley, sprocket or timing gear which can be mounted on a shaft so that the plane of the rotatable member may be positioned at selected angles other than a 90° angle to the axis of rotation of the shaft. A torque transmitting member, commonly in the shape of a planar disc, is used to operatively connect the shaft and the rim of the rotatable member. The disc radially elongates and laterally flexes as the rotatable member rotates. A sleeve member may be used to connect the disc to the shaft. When used as a driver, a key may be used to transmit power from the shaft to the sleeve. The use of an elongated groove in the shaft permits the rotatable member to be adjustably moved to different locations along the axial length of the shaft.
