Title: Top drive torque reactor
Inventor: MOSES JOHN K
IPC: E21B3/02
Filed: 1989-05-08
Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE      A torque reactor for a top drive drilling rig converts reactive torque on the top drive housing into a rotational torque on a torque shaft.   The torque shaft extends vertically in the derrick parallel with the drive stem.   A torque case carries two bushings, one of the bushings receiving the drive stem of the top drive and  the other  slidingly receiving the torque shaft.  The drive unit bushing is rigidly connected to the housing of the top drive.  The torque shaft bushing will   transmit rotational force to the torque shaft. Linkages interconnect the bushings.  Rotational torque imposed on the drive unit bushing creates a rotational torque in the torque shaft bushing.   That torque is transmitted  to  the  torque  shaft  which  is  held stationary to absorb the torque.

Abstract: Title Rotational Control Apparatus ABSTRACT OF THE DISCLOSURE   A rotational control apparatus in the preferred form of a fan clutch is disclosed including a friction disc portion slidably mounted and rotationally related by splines on a hub in turn rotatably mounted on a fixed shaft.  The splines are formed on a radially outermost portion of the hub.  A washer abuts with a shoulder formed in the hub at the intersection of a radially reduced portion with the radially outermost portion and with a retainer on the free end of the radially reduced portion sandwiches a spring in a compressed condition on the reduced portion.  In an assembled relation, the friction disc portion abuts with the washer such that the spring biases the friction disc portion.  The friction disc portion may be slid from the hub without removal of the hub from the shaft and with the spring retained on the hub by the washer.  Both sides of the friction disc portion taper together such that the thickness therebetween decreases with the radial spacing from the rotational axis.  The axial side of the friction disc portion which interfaces with the friction lacing includes a first, radially straight circumferential portion extending radially into a second, radially angled, circumferential portion extending axially rearward to a third, generally radially straight, circumferential portion.

The output signal of variable gain amplifier (5) is applied to an FM demodulating circuit (7) constituting a PLL circuit via a BPF (6). The output signal of BPF (6) is also applied to a synchronous detector (12) via a 90° fixed phase shifter (11).  The output signal of a VCO (10) included in the PLL circuit is applied to synchronous detector (12) as the reference signal.  The synchronous detector (12) is responsive to the reference signal for synchronous detecting the output signal of 90° fixed phase shifter (11).  The output signal of synchronous detector (12) is applied to variable gain amplifier (5) via a LPF (13) as the gain control signal.  Thus, variable gain amplifier (5) is responsive to the output signal of synchronous detector (12) for making the amplitude of the FM audio signal included in the FM signal constant.

Abstract: The invention relates to a device for separating liquid and/or solids from a high-pressure gas stream, comprising a cylindrical vessel with a virtually vertically set axis fitted with a top compartment to which the gas stream is fed; a middle compartment comprising a number of blades set helicoidally around the axis; a bottom compartment for separating the gas and the liquid and/or solids and a coaxial gas discharge pipe projecting upward from the bottom compartment through the middle and the top compartments, around which helicoidal blades have been fixed, each helicoidal blade being composed of a bottom section with a constant pitch and a section with a pitch gradually increasing in upward direction. The constant pitch of the blades lies between 5 and 20°, preferably between 10 and 15° and increases in upward direction to at most 60°, preferably 45°.

These baffles are shaped like flat planes with sharp free ends. Conical sleeve sections are provided in the separation section of the device, at the outer wall of the gas discharge pipe, the angle between the sleeve sections and the centre line of the vessel being between 15 and 45°.

Title: Analyte specific chemical sensor
Inventor: ISSACHAR DAVID
IPC: G01N33/68
Filed: 1990-09-04
Granted: 2002-05-28
Abstract: An analyte specific chemical sensor for determining an analyte in a test medium. The sensor comprises a sensing surface which is coated with reversible competitive recognition units (RCRUs) each of which contains as constituent components at least one receptor and at least one ligand, one of which components is an analyte analogue.      In these RCRUs the receptor and the ligand are a priori connected to each other, directly or indirectly, in such configuration that even when, for example, an analyte analogue ligand is displaced from the receptor by an analyte ligand, the analogue will still be retained in relatively close proximity to the receptor. In addition, the relative positions of the receptor and the ligand in the RCRU are such that when no analytes are present or when the analyte concentration is at a low level, they are affinity conjugated by a specific affinity interaction. The fluctuations of analyte concentrations in the test sample affect the chemical occurrences at the RCRUs, and consequently the physico-chemical characteristics of the components thereof. The changes in the analyte concentration are monitored, according to the present invention, by continuously measuring the changes of the above physico-chemical characteristics induced by occurrences at the RCRUs, namely the inner association and dissociation thereof. Such physico-chemical characteristics may be, for example, photochemical, e.g. light absorption, light emission, light scattering and light polarization; electrochemical; and piezoelectrical.
