Patent GB-2176800-A (GB)
Title: Hydrocarbon separation with a physical solvent
Inventor: MEHRA YUV R
IPC: C10L3/10
Filed: 1985-08-05
Abstract: A stream of natural gas (13), which is rich in C5+ hydrocarbons and may be wet or dry or sweet or sour, is extracted in two stages (11, 12) with a physical solvent. In the first stage (11), a major portion of the solvent, containing up to an equilibrium amount of C5 + hydrocarbons, removes substantially all of the water and the C2 + hydrocarbons. In the second stage (12), the partially stripped natural gas is countercurrently extracted with a lean-and-dry minor portion of the solvent which contains less than 1% by weight of water and less than 1% by volume of hydrocarbons. The residue natural gas, which is then sent to a pipeline, contains less than 7 pounds of water per million standard cubic feet. The rich solvent is flashed to atmospheric pressure in at least two stages, forming a methane-rich vapor portion which is suitably recycled to the first extraction, a methane-poor vapor portion, and a flashed solvent containing up to equilibrium amounts of C5 + hydrocarbons. The methane-poor vapor portion is compressed, cooled, and condensed to form a liquid stream which is selectively stripped of C1, C1+C2, C1+C2+C3 or C1+C2+C3+C4 to form a liquid hydrocarbon product of selected composition based on market economics. A slipstream of the flashed solvent, containing the amount of water picked up from the natural gas stream and amounting to less than 25% by weight of the flashed solvent, is all that needs to be regenerated to form the lean-and-dry minor portion.

Title: Formwork beams
Inventor: SZUCS ANDRAS
IPC: E04G11/50
Filed: 1986-05-01
Abstract: Description is given of extruded aluminium structural beams (20) having their cross-sections shaped for cooperation with connecting means, said connecting means being used for assembling continuous support lengths of desired dimension in each application by connecting said beams in series with variable overlap of their ends. According to the invention beam (20) includes support surfaces (26,28) located on side of beam with lesser projection of flanges (25,27) said surfaces lying in planes convergent towards main axis (46) said axis being perpendicular to plane of flexure. Line of action (39) of support forces is directed towards plane of web (45) and has inter-section (47) with it within the cross section. In such arrangement internal stresses due to eccentricity of support forces are substantially reduced. Torsioin of the beam (20) due to support arrangement is lessened by the proximity of the shear centre (38) to the plane of joint (37). Joints of the beam are held together by bolt-heads engaging in T section slots at the end of the flanges. <IMAGE>

Patent GB-876026-A (GB)
Abstract: 876,026. Measuring rotor unbalance. AVERY Ltd., W. & T. Feb. 11, 1958 [June 21, 1957], No. 4352/58. Class 40 (1). [Also in Group . XXXVI] The magnitude and position of unbalance of a rotating workpiece are determined by energizing one coil of a wattmeter with signals from an unbalance-responsive pick-up and the other coil with alternating current synchronized with the rotation of the workpiece, the amplitude of this alternating current being varied in accordance with the position of the unbalance so that the wattmeter indicates the magnitude of the unbalance. In Fig. 1 the workpiece 1 is mounted on a spindle 2 which also carries the moving coils of transmitters 5 and 6, and is fitted with unbalance-responsive pick-ups 7 and 7<SP>1</SP>. The signal from 7 is applied to the moving coil of a receiver 9 which is similar to transmitter 5 in that it has two fixed pole-pairs 90 degrees relative to one another, and corresponding field coils of instruments 5 and 9 are connected together. The moving coil of transmitter 5 is energized with D.C., and the rotating field communicated to receiver 9 combines with the field due to the signal from 7 to set the pointer 10 in a position which represents the position of unbalance with respect to a predetermined datum point. The transmitter 6 generates two voltages 90 degrees displaced from one another, and these are fed to a 360-degree potentiometer 12 in the manner shown in Fig. 2. The first part, of each quadrant of this potentiometer has its resistance graded according to a sine law and the second part according to a cosine law, and the moving contact is driven from the spindle of pointer 10, so that the signal fed to the field coil 13 of the wattmeter 16 varies sinusoidally in accordance with the position of unbalance. The moving coil 15 receives signals from the imbalanceresponsive pick-up 7<SP>1</SP> and the wattmeter thus indicates the magnitude of unbalance. Specification 805,036 is referred to.

Title: D. C. solenoid control circuit
Inventor: VERBOS STEPHEN P
IPC: F16D55/28
Filed: 1988-01-12
Abstract: A D.C. solenoid 15 control circuit such as for energising the solenoid in a braking mechanism in a hoist driven by an A.C. motor, 12, includes a rectifier 34 for converting A.C. to D.C. and providing an A.C. flow path and a D.C. flow path. The D.C. solenoid 15 is connected in the D.C. current flow path through the rectifier and drives an actuator within the solenoid. This activates a device such as the braking mechanism. High starting (in-rush) current drawn by the motor is converted to a high current level by the rectifier and input to the winding of the solenoid causing its immediate energization and first release of the spring biassed brake. The high starting current decreases during operation of the motor, resulting in a low holding current in the solenoid, sufficient to maintain the brake released. Because of the low holding current, the spring is released quickly on deactivation of the motor <IMAGE>
