Title: Equipment for the anaerobic purification of waste water
Inventor: VELLINGA SJOERD H J
IPC: C02F3/28
Filed: 1987-05-01
Granted: 1992-07-21
Abstract: ABSTRACT     To avoid considerable vertical and horizontal flows in the settler formed by gas collection hoods, of the upflow anaerobic sludge blanket (U.A.S.B.) reactor, each gas collection hood debouches at one or two ends into a gas collection chamber via one or more openings, the upper boundary of said openings being situated below the inside surface of the projection or the top of the hood concerned.  The gas collection hoods are situated immediately below the level of the effluent discharge and the depth of the settler is shallow.  As a result of the decrease in pressure only a few gas bubbles are consequently liberated and the settling of the sludge is not appreciably disturbed.

Title: Address transform method and apparatus for transferring addresses
Inventor: BARLOW GEORGE J
IPC: G06F12/02
Filed: 1988-02-08
Granted: 1992-04-21
Abstract: ABSTRACT OF THE DISCLOSURE An address path which transfers addresses from a number  of  sources  includes  an  incrementing  circuit. The address includes a plurality of  address bits and integrity bits.   The address bits are applied to the incrementing  circuit  while  the  integrity  bits  are applied  in  parallel  to  a  programmable  logic  device (PLD).    While  the address  is  being  transferred  or incremented   as   required,   the   PLD   independently generates  a  number  of  transform  bits  defining  a characteristic of the number of address bits predicted to change state.   Thereafter,  the transform bits are used  to  transform  the  address  integrity  bits  for transfer with the incremented address.  The incremented address,   transform   bits and   integrity   bits   are logically combined for verifying that the address was transferred and/or incremented without error.

Abstract: An immunoassay utilizing a biotin bridge is performed with a solid phase with anti-biotin immobilized on its surface.  In accordance with the assay, the solid phase is incubated with a biotinylated binding species, preferably biotinylated antibody, specific for the ligand to be detected.  This is then reacted with the test sample,  followed by a labeled binding member, either in a sandwich type or competitive-type binding assay.  The label is then detected in accordance with conventional detection techniques.  Use of the solid phase with only a biotin-specific antibody attached thereto expands the utility and versatility of a single solid phase for use in the detection of an unlimited variety of ligands.
