IPC: H01Q21/24

Abstract: An angular error detecting device in which all components of arriving polarized waves are obtained independent of the type and amount of polarization. A higher mode detector (2,3) outputs two higher mode components which are in orthogonal relation. These two components are combined so as to maintain the orthogonal relation. A circuit is provided having a set of at least one 90° phase difference plate (4) and one 180° phase difference plate (5) which have rotatable phase lag surfaces and which are cascade-connected. The 90° phase difference plate (4) is provided on the side of the circuit combining the two higher order components. The output of the 180° phase difference plate (5) is divided into first and second orthogonal polarization components. The first polarization component is synchronously detected with a local oscillator output synchronous with reference signals to provide a first angular error output while the output of the second polarization component is synchronously detected with signals shifted 90° in phase from the local oscillator output to thereby provide a second angular error output orthogonal to the first angular error output.

Abstract: A dosage unit for dosing a number of measured quantities of a liquid, such as an insulin prepara­tion, from a separate cartridge (2), where the dosage unit comprises a cylindrical casing for the cartridge (2). At the distal end the casing (1) is provided with means for fastening a liquid outlet needle (5). The dosage unit comprises fur­thermore a piston rod (8) activating a piston (4) in the cartridge (2). An adjustment means (18) is pivotally mounted on the casing and determines by way of adjustment the length of the stroke of the piston rod. A ratchet device (10, 11) is situated between the casing (1) and the piston rod (8), said ratchet device allowing displacement of said piston rod (8) towards the distal end of the casing (1) and preventing a displacement thereof in the opposite direction. The adjustment means (18) is non-displaceably mounted on the casing (1), and the piston rod (8) is provided with an external thread (12) and prevented from rotating relative to the casing (1). A nut means (13) is provided between the piston rod (8) and the adjustment means (18) said nut means engaging by way of an internal thread the thread (12) of the piston rod (8) and on the outside engaging in an axially displaceable manner the adjustment means (18). A rotation of the adjustment means (18) involves a rotation of the nut means (13) relative to the piston rod and   consequently a displacement of an indicator (21) fixedly connected to the nut means (13) and protrud­ing from the end of the adjustment means (18). The indicator (21) is provided with a measuring scale indicating the extent of its axial displacement relative to the adjustment means and consequently the desired dosing quantity, whereby the dosing is carried out by pressing the piston rod (8) by way of the indicator (21) while pressing it back to­wards the interior of the adjustment means (18)

Abstract: A test device and method of determining the presence and concentration of the total pro­tein content, including albumin and Bence Jones proteins, in a test sample. The test device in­cludes a test pad comprising a new and improved carrier matrix incorporating an indicator reagent composition capable of interacting with proteins to produce a visually or instrumentally detectable and/or measurable response. The new and improved carrier matrix of the test pad comprises a fibrous, bibulous substrate, such as filter paper, homogeneously impregnated with a polymerized urethane-based compound. The new and improved carrier matrix provides improved color resolution and increased sensitivity to proteins in dry phase test strip assays, thereby affording a more accurate and trustworthy protein assay of liquid test samples, such as urine. Furthermore, by utilizing a carrier matrix comprising a fibrous, bibulous substrate homogeneously impreg­nated with a polymerized urethane-based compound, a dry phase assay for low molecular weight pro­teins, such as Bence Jones proteins, can be per­formed on a liquid test sample.
