Title: Process for the removal of gas or liquid residues from solvents used to treat gases or liquids
IPC: C07C7/10
Filed: 1966-12-22
Abstract: 1,131,989. Separating gases. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 22 Dec., 1966 [24 Dec., 1965], No. 57394/66. Heading B1L [Also in Division C5] Impurities, such as H 2 S, SO 2 , CO 2 , COS, NH 3  or amines, present in scrubbing solvents which have been contracted with such gases or vapours as air, natural gas, combustion products of coal or oil, refinery gas, town gas, coke oven gas, water gas, H 2 , CO, N 2 , O 2 , water vapour and light hydrocarbons such as propane and propylene, are separated from gas or liquid residues of the gas or vapour being treated which are present in the solvent by treating the impurity-containing solvent at a pressure lower than that obtaining in the scrubbing zone with a second quantity of solvent in the presence of more of a gas or liquid which is to be similarly processed. As shown, gas or vapour stream 1 flows in countercurrent to solvent stream 3 in column 2 maintained at 7-70 kg./cm<SP>2</SP>, scrubbed gas or vapour leaving at 4. Solvent rich in impurities and containing residues of the gas or vapour leaves by line 5 and passes to column 18, which is at a lower pressure than column 2, where it encounters a rising stream 19 of a gas or liquid to be scrubbed and a falling stream 16 of fresh scrubbing solvent. Impurity-free gas or liquid leaves at 20, while laden solvent passes by line 21 to stripper 13, the impurities leaving at 15. Commonly, the principal impurity is H 2 S, in which case stream 15 is desirably treated with an oxygencontaining gas so as partially to oxidise the H 2 S to elementary sulphur. In both scrubbing zones, the temperature is suitably maintained at 25-135‹C, preferably 30-80‹C. A number of conventional solvents are listed as suitable scrubbing media for particular purposes; an especially suitable one comprises by weight 1-15% water, 15-35% diisopropanolamine and 50-84 % sulpholane (cyclotetrahydromethylene sulphone).

Title: Magnetic bearing
IPC: H02K7/09
Filed: 1971-12-14
Abstract: 1342919 Automatic control of position P A STUDER 14 Dec 1971 [22 Dec 1970] 57951/71 Heading G3R [Also in Division F2] A magnetic bearing comprises a stationary ring 25 of low reluctance material carrying a coil 24 wound to produce axially directed magnetic poles, and a magnetic assembly including a pair of coaxial toroidal permanent magnets 21, 22 having axially directed magnetic poles as indicated, the magnetic surfaces adjacent each other having a like polarity so that the magnets tend to repel each other along their common axis 23. Associated with the magnets are a central ring 31 and annular end jackets 26, 27 of low reluctance material which co-operate with the stationary ring 25 to define air gaps 34, 35, 36, 37 in series. Thus the magnetic assembly, to the interior of which is fixed the shaft (not shown) to be supported, floats with respect to the stationary ring 25 and is held in position by the forces between the ring and the magnets. The arrangement is such that the permanent magnets 21, 22 provide the primary force tending to hold the shaft in situ, the magnetic flux from the magnets passing from left to right through air gap 34 and from right to left through air gaps 35; the flux from the coil 24, however, passes from left to right through both gaps, boosting the flux in gap 34 and bucking the flux in gap 33 and thus determines the position of the floating assembly relative to the stationary ring 25. To establish stability for this position, variations in the size of the gap 37 are sensed by a detector 51, 52 the output from which is applied over an amplifier 19 to control the energisation of the coil 24 in a corrective manner. The detector may take the form of a capacitive, magnetic, optical or other sensor. The electromagnetic flux path is of low reluctance because it includes only the ring 25 and arms 32, 33 of the central ring 31 and thus the power requirement to attain stability is relatively low.

Abstract: 586,103. Hydraulic machines. KEELAVITE CO., Ltd., and LEVETUS, F. B. Dec. 14, 1944, No. 25079. [Class 69 (ii)] In a pump C and motor G, hydraulic system having a valve J for controlling the rate of fluid flow through the motor, an additional valve L varies the rate of supply to the motor in accordance with the pressure drop across it, in order to compensate for slip, caused by leakage through the motor and varying with the load. Valve L may be arranged in parallel with control valve J and may comprise a valve member subjected on its opposite ends to the pressures at the inlet and outlet of the motor. The valve members byepass flow to the reservoir A with increase in pressure drop in the motor. Alternatively, the slip compensating valve may be in parallel with the motor, in which case it reduces flow through the byepass with increase 'in pressure drop. In each case flow through the motor increases with increase in pressure drop across the motor, and vice versa. The control valve may be disposed on either side of the motbr and may be of the type in which a constant pressure drop is maintained on either side of a control orifice, thereby ensuring constant flow at all pressures. A relief valve E is provided.

Title: Apparatus for washing vehicles
IPC: B60S3/06
Filed: 1969-12-02
Abstract: 1,260,207. Washing apparatus for vehicles. BOEWE, BOEHLER & WEBER K.G. 2 Dec., 1969 [3 Dec., 1968; 10 May, 1969; 27 Sept., 1969], No. 58690/69. Heading B7J.  An apparatus for washing a vehicle moved relative thereto comprises a rotatable brush 9 mounted on a guide device 5, 8, to move transversely with respect to its axis of rotation and substantially in a straight line' as indicated by the/arrow 19 in Fig. 2, the guide device being pivotal with respect to a support 2, 3 having a fixed axis coincident with, Figs. 1 and 2, or alternatively parallel to Fig. 13 (not shown), theaxis of rotation of the brush 9, the direction of this fixed axis extending from above, Figs. 1 and 2, or from the side, Figs. 18-26 (not shown), of the vehicle at right angles to the direction of movement of the vehicle and passing through the surface thereof, the brush 9, when displaced from a starting position, being movable back into this position by a restoring force. In the embodiment of Figs. 1 and 2, the guide device comprises two arms 5, 8 pivotal about joints 6 and 7 respectively as well as about the support, which comprises a pivot support 2 and rotatable pin 3, and the restoring force is provided by a cylinder 28 interconnecting the arm 5 and support 2, 3. The arms 5, 8 are interconnected by a coupling device comprising two pulleys 20, 22 fixed in the same plane to the arm 8 and to a lateral extension 4 of the pin 3 respectively, and an interconnecting cable 21, the ends (23, 24) of which are fixed, the latter via a spring (25). The coupling causes the arms to move in opposite directions of rotation and substantially diagonally to the movement of the brush 9. A further cylinder 13, fed with a pressurized medium via a reversing valve controlled by switches 39 and 43, actuated by the vehicle or the arm 5, causes the pin 3 to pivot between two limiting positions. Rotation of the pin 3 causes the brush and guide device to move from the position shown in solid lines in Fig. 6 to that shown in dotted lines, thus allowing the brush sufficient rotation about the support 2, 3 to enable it to wash the front, side and rear surfaces of the vehicle. The movement of the apparatus of Figs. 1 and 2 during a car washing cycle is shown in Figs. 4-9. In an alternative embodiment of the invention the coupling device and cylinder 28 are replaced by two springs, one connecting the two pivotal arms, the other connecting the arm 5 to the pin 3. In a further embodiment the brush is mounted in a guide rail arranged pivotally about the fixed axis, which is located substantially half way along the length of the rail. In a further embodiment the cylinder 13 is replaced by a motor such that the pin 3 can rotate through at least 360 degrees. The brush and guide device may be mounted about horizontal axes as described with respect to Figs. 18 to 26 (not shown) in which case only the ends and upper surfaces of the vehicle are washed.

Abstract: 1387150 Shock absorber piston valves; valves MONROE BELGIUM NV 29 Dec 1972 [30 Dec 1971] 60126/72 Headings F2S and F2V A shock absorber piston valve comprises a passage 84, and two adjacent, valve members 86, 98 movable to "close" or "open" the passage 84, each valve member having an orifice or notch 96, 100 in communication with the passage. On rebound movement of the piston at low speeds, liquid flows through the passage 84, the orifice 96 and the notch 100 without unseating the valve member 86. At high speeds, the valve member 86 moves away from its seat against the bias of a spring 90 to reduce the resistance offered by the valve. The two orifices or notches 96, 100 in series eliminate the swishing noise which arises when there is only one bleed notch. In Fig. 3 (not shown), spacer members 102, 104 are replaced by disc springs (107) which bias the valve members 86, 98, the coil spring being omitted. In Fig. 4 (not shown), the rebound valve comprises two of the Fig. 3 valves in series, i.e. for low piston speeds a flow path containing four orifices in series. The piston is part of a tube within-a-tube shock absorber (Fig. 1, not shown) with conventional base valve and piston compression valve.

Title: Travelling-wave regenerative laser amplifier
IPC: H01S3/139
Filed: 1970-12-21
Abstract: 1,272,727. Lasers. UNITED AIRCRAFT CORP. 21 Dec., 1970 [20 March, 1970], No. 60511/70. Heading H1C. A laser amplifier 18 has a gain: losses ratio such that it is just below the point of oscillation, and is stimulated by an input from a separate spectrally pure laser 10. This input is of relatively low power but fully saturates the amplifier medium even close to the point of entry thereto because the amplifier is near to oscillation. This produces a pure output at a high power, the output being phase locked to the reference input from laser 10. The amplifier is shown in Fig. 1 as a gas laser tube 18 in a ring cavity, the tube having a high gain but the cavity reflectors being chosen with losses which prevent oscillation. The reference beam is injected into the ring through mirror 12. The laser tube 18 is pumped by a constant current discharge supplied from source 40. Mirror 14 is mounted on a transducer 22 fed with a dither signal from an oscillator 30, and the resonant frequency of the ring is thus varied. This causes a variation in the gain of the ring amplifier at the reference frequency and hence in the output power. This in turn produces a variation in the impedance of the pumping discharge plasma and hence in the voltage across it. The varying voltage is fed via capacitor 42 to a synchronous detector 26 which drives amplifier 24 to adjust mirror 14 until the output power is maximized. The ring may contain more than one laser active medium, e.g. others may be placed at 16, 17, Fig. 1. Refracting or diffracting devices such as prisms or gratings may replace one or more of the ring mirrors. The output from the ring need not be from the same mirror as that through which the input passes, Fig. 2 (not shown). The resonance adjusting circuitry may monitor the output flux directly instead of measuring the plasma impedance.
