Patent NO-170869-C (NO)
Inventor: ROESSLER BERNWARD
IPC: H03M1/00
Filed: 1986-09-17
Abstract: It contains a network of capacitors, the capacitance of which is graded in a binary manner and the one terminals of which, which represent base points of the network, can be connected to a reference potential or, in the case of low-significance bits of digital information items to be converted, to earth potential or to a fraction (UB, U4) of the reference potential. To avoid problems which could arise from the offset voltage of an integrated operational amplifier (V) connected to the network, the network is constructed of two symmetrical halves (C0o' to C32o; C0n' to 32n).

Granted: 1997-09-30
Abstract: Apparatus and method have been conceived whereby cut sheets having a bar code printed thereon can be read while such sheets are moving.  A fixed scanner for reading the bar code has an elongated window such that a light beam being generated by the scanner will have a width that is no greater than the width of the smallest space between adjacent bars of the symbol.  Because of the elongated configuration of the light beam, sufficient reflectivity occurs such that a good reading can be obtained with the use of such a fixed beam scanner.

Title: Two-link, trip-free operating mechanism for use in a switch assembly
Inventor: VIANSON PAOLO M
IPC: H01H33/40
Filed: 1991-08-14
Granted: 1995-08-01
Abstract: A two-link, trip-free operating mechanism assembly for a switch includes a first pivotally-mounted link comprising a switch lever arm.          One end of the switch lever arm is coupled to the switch and a second end of the switch lever arm has a roller mounted thereto. A second link assembly includes a pivotable support member to which a cam member is mounted for rotation. The pivotable support member is selectively fixed during the closing of the contacts, or movable between a contact-closed position and an overriding open position. The cam member controls the state of the switch. In the tripped condition, the cam member and the roller are disengaged and the switch assumes a tripped, or open, state.     A first spring arrangement applies a force to the link arrangement to cause the links to close from an open position. For trip-free operation, a second set of springs forces the switch arm link to immediately move to a switch-open position. The trip-free operation functions so that the switch assembly can be tripped back to its open position at any time.

Abstract: The present invention includes novel assays employing a capture reagent, involving a first binding member conjugated to a polymeric anion such as carboxymethylamylose, and a solid phase material containing a reaction site comprising a polymeric cation substance. A test sample suspected of containing the analyze of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. The use of carboxymethylamylose to prepare a suitably charged capture reagent provides a superior capture reagent that is capable of binding and retaining the analyze on the solid phase even in the presence of polyanionic non-specific binding blockers.
