Title: Phase detector
IPC: H03D13/00
Filed: 1990-06-18
Abstract: A phase detector is provided for detecting the phase difference between a first input signal and a second input signal and providing an output corresponding thereto. The phase detector comprises a dual state phase detector, a tri-state phase detector, a control input for receiving a control signal, and a control circuit for selecting either the dual state phase detector or tri-state phase detector. The dual state phase detector compares the phase difference between the first input signal and the second input signal. The tri-state phase detector compares the phase difference between the second input signal and the inverse of the first input signal. The control circuit selects the output of the dual state phase detector or selects the output of the tri-state phase detector based upon the control signal.

Abstract: Abstract of the Disclosure An improved NRZ clock and data recovery system lends itself to integration  includes a NRZ phase detector, an NRZ frequency detector and a lock detector, and provides automatic centering of the clock edge within the bit interval in 2 manner that is independent of analog relays and process and temperature variations.  NRZ data is applied to one side of an exclusive-OR sate (6) and a twice delayed (2 4) version of the NRZ data is applied to the other side.  The output of the XOR gate (6)  a "blivet" signal  is applied to a NRZ phase detector (10) comprising two AND sates (12,14), one of which (12) has as its other input a recovered clock signal output of a VCO (20) and the other of which has as its other input an inverted (16) version of the recovered clock signal.  The "up" and "down" outputs of the AND sates (10,12) indicate which direction a frequency control signal (26) should change the VCO (20) frequency.  A data holding flip-flop (28) whose input is a once delayed (2) version of the NRZ data is clocked with the recovered clock signal.  The NRZ frequency detector (50) monitors the state of the recovered clock signal on opposite edges (52, 53) of the blivet to detect too-high (56)  too low (55) and good (54) conditions.  The results of the detection can be ignored if a lock signal indicates that the phase lock loop is locked.  The lock detector (30) consists of a saturating up/down counter (42) that is incremented (38) by one when good blivets (32) occur and is decremented (40) by four when not-good blivets (36) occur.

Title: Uniformly-cooled casting wheel
Inventor: GEORGE PAUL E II
IPC: B22D11/06
Filed: 1991-03-12
Abstract: Metal strip (9) cast directly from the melt onto a cylindrical casting drum (20) is made more uniform in thickness and in structure by making the temperature of the casting surface and, therefore, heat transfer more uniform, thus reducing distortion of the casting surface. This is accomplished by a novel arrangement of helical coolant channels (25) extending below the casting surface (10) and in heat transfer relationship with the casting surface and being at an angle of between about 15· and 75· (and preferably between about 45· and 75·) to the drum axis. At least one coolant inlet (21) and one coolant outlet (22) supply and withdraw coolant to each channel. In one embodiment, inlets (21a, 21b) are alternated on the same side of the shell with outlets (22a and 22b) of adjacent channels so that the cooler regions around inlets are alternated with higher temperature outlet regions to balance the temperature around the surface.

Title: Assay technique
Inventor: ROBINSON GRENVILLE A
IPC: G01N27/327
Filed: 1991-10-14
Abstract: The invention relates to a competitive binding assay technique for substances (e.g. small molecules having no antigenic de-terminant) which can serve as substrates for coenzyme-requiring enzymes. The technique involves contacting a liquid sample with an assay system including (i) a substrate analogue and (ii) a moiety capable of binding specifically to the substrate. The substrate analogue is a substance capable of binding to the said moiety competitively with any of the substrate present in the sample. The presence or amount of the substrate is determined by monitoring the extent to which there are formed or remain complexes be-tween the said moiety and substrate analogue and/or substrate respectively.
