Patent GB-2233091-A (GB)
Title: Immunoassays using monoclonal antibodies directed against natural binding       proteins
Inventor: BENNER CHARLES WALTER
IPC: G01N33/577
Filed: 1989-01-27
Abstract: Monoclonal antibodies or immunoreactive monoclonal antibody fragments specific for naturally occurring binding proteins are used to form a monoclonal antibody-binding protein complex by which to detect a ligand in a variety of immuoassay formats. These antibodies or fragments can be labeled or unlabeled and when they are unlabeled then the unlabeled antibody or fragment is reacted with a labeled antibody specific for the unlabeled antibody or fragment. This approach preserves the inherent affinity of the binding protein for the ligand.

IPC: H03M1/68
Filed: 1991-03-14
Abstract: An interpolation DAC includes first and second registers 12, 24 which receive the X least significant and Y most significant bits of a digital input word and are clocked at a first clock rate C2. A third register 16 is coupled to an adder 14 and is clocked at a second clock rate C1 which is faster than the first clock rate C2 by a factor equal to the desired oversampling ratio. A Y bit plus 1 bit DAC 30A in which the 1 bit is a duplicate of the least significant of the Y bit section has its most significant Y bits coupled to receive the outputs of the second register 24. The duplicate LSB is connected to receive the carry output from the adder 14. A low pass filter 32 is connected to the output of the DAC 30A to produce an analog output representative of the digital input word. The digital-to-analog conversion rate of the Y bit section of the Y bit plus 1 bit DAC 30A can be performed at the slow first clock rate C2. <IMAGE>

Title: A depth measuring float
Inventor: BESWICK GEORGE STANTON
IPC: G01F23/38
Filed: 1991-12-21
Abstract: A depth measuring float comprising two hemispherical buoyancy chambers (11) hinged together at (7) and adapted to be closed by a catch (6). Between the chambers (11) is mounted a fixed slotted boss (2) about which is pivotally mounted an arm (1) having an annular slotted boss (14) and a hook-line formation (8) around which line (9) passes to extend through aligned slots (13, 15).

Title: Apparatus and method for controlling the angle of a head drum of a tape player/recorder
Inventor: YOO JAE CHERN
IPC: H04N9/83
Filed: 1992-03-17
Abstract: A video cassette recorder, in which the head-drum angle is controlled by the control voltage which varies according to the tape speed detected from the frequency of capstan motor applied by the frequency detecting portion at the first stage. Then, based upon the Fuzzy theory, the video head of head-drum can be maintained in a constant angle with the pitch (P) of video tape independent of the tape speed by reproducing the control voltage by means of the detected membership function detected according to the gain difference (G) coming from the gain detecting portion. The head angle control means and head tip displacement means are controlled by a microcomputer (MC) which is connected to the outputs of a frequency detecting means (capstan motor) and gain detecting means (video head signal). <IMAGE>
