Patent CA-2022518-A1 (CA)
Title: Heterogeneous binding assays
Inventor: WATTS RICHARD P
IPC: G01N33/537
Filed: 1990-08-02
Abstract: ABSTRACT OF THE DISCLOSURE      A method for carrying out a binding assay is described wherein a member of a specific binding pair (sbp) and a sample are combined with a matrix of non-porous beads in a liquid medium under conditions such that the beads bind to the sbp member.  The liquid medium is removed from the beads by aspiration using an aspiration tube having one or more orifices each of a diameter smaller than the minimum diameter of the smallest bead thereby allowing removal of the liquid medium while prohibiting aspiration of the beads.

Abstract: ABSTRACT RECLINING CHAIR                     A chair which is provided with a seat having an adjustable inclination comprises a seat carrier, which is pivoted by a first pivot to link means which carry the seat, a back rest, which is car-ried by a back rest carrier, which is pivoted to the link means by a second pivot, and means for shifting the chair from a position for work, in which the seat is approximately horizontal and includes with the back rest an angle of about 90 degrees, to a position for reclining, in which the seat is rearwardly inclined and includes an obtuse angle with the back rest. The shift from the position for reclining to the position for work is effected by movements of the body of the occupant and is assisted by spring means. The seat carrier is provided with slide bearings and slots,  n which the first pivot is displaceable away from the column as the chair is shifted to its position for reclining. The pivotal movement which is imparted to the back rest by the movement of the body of the occu-pant is adapted to be transformed to the displacement by means of gearing means comprising pairs of levers. Owing to that design, the center of gravity is dis-placed so that the back rest can be swung further to the rear without a risk that the stability of the chair might be endangered.

Abstract: The present invention relates to a free radical emulsion polymerization process. The latex is prepared by polymerizing (a) at least one conjugated diene, (b) at least one non-carboxylic vinyl aromatic or aliphatic comonomer selected from the group consisting of styrene, .alpha.-methyl styrene, p-methyl styrene, vinyl toluene, acrylonitrile, methacrylonitrile, vinylidene chloride, ethyl acrylate; butyl acrylate, vinyl pyridine, methylmethacrylate, hexylacrylate, 2-ethyl hexyl acrylate or mixtures thereof, and (c) at least one ethylenically unsaturated carboxylic acid monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, 3-carboxyethylacrylate, itaconic acid or mixtures thereof. The process of the present invention is characterized by (a) initially polymerizing the non-carboxylic comonomer in the presence of the unsaturated carboxylic acid and in the absence of any conjugated diene to a conversion of 3 to 12 percent to form a partially polymerized latex; and thereafter (b) copolymerizing the conjugated diene with the unreacted non-carboxylic comonomer in the partially polymerized latex. The present process mitigates the formation of codimers of the conjugated diene and non-carboxylic comonomer. The present process also provides a latex having unique film forming characteristics and polymer morphology leading to unique film stiffness and stress-strain relationship.

Title: Image cancelling mixer circuit on an integrated circuit chip
Inventor: ATHERLY DON H
IPC: H03D7/16
Filed: 1990-07-30
Abstract: An IF mixer circuit (10) in a receiver implemented in integrated circuits employs a pair of doubly balance mixers (22, 46), one injected with a local oscillator reference signal in phase while the quadrature phase of the reference signal is injected into the second mixer. A phase shift circuit (42) adds another 90° phase shift to the output of the second mixer (46), and the in-phase and out-of-phase signals are applied to a summing circuit (40) to attenuate unwanted mixer products and reinforce the desired IF sig-nal. The balanced elements of the 90° phase shift circuit (42) employ a transistor (61) with equal emitter and collector resistances, a diode-connected transistor (63) in series with the collector load resistance (65), and a collector-to-base capacitor (67), which pro-vide a constant-amplitude phase shift in a unity gain structure independent of current, to produce a precise 90° phase shift. Emit-ter current is adjustable to compensate for production variation in the absolute value of the fixed resistance, i.e., by varying the current in the transistor and diode, the dynamic resistance offsets the fixed resistance variation.
