Title: An apparatus for automatically controlling the level of a liquid in a container suchas a tank
IPC: G05D9/04
Filed: 1963-08-16
Abstract: 971, 864. Controlling liquid levels. AJINOMOTO CO. Inc. Aug. 16, 1963 [Aug. 17, 1962], No. 32541/63. Heading G1H. An apparatus for automatically controlling the level of liquid 5 in a container comprises a float 2 situated within the container and provided with an inner tube 9 which has a gas inlet hole 4 and a gas escape hole 10, a free rolling ball 8 situated within the tube 9 and capable of closing the inlet hole 4, a control valve 11 for controlling the flow of liquid by means depending on gas pressure, and a flexible tube 1 connecting the valve 11 to the inlet hole 4 through a tee-junction 3 from which a tube leads to the gas supply. The gas used is preferably air and the valve 11 is arranged so that the air pressure acts on a diaphragm to move it against the action of a spring to close the valve and stop liquid flowing into the container through a tap 19. The float 2 is mounted on the end of the flexible tube 1 and is retained in position by a short tube 6. If the liquid level falls the ball 8 rolls to the end of the tube 9 with the escape hole 10 and the air thus escapes the pressure in the system being atmospheric so that the valve 11 is open. As the container fills the ball 8 eventually seats on and closes the inlet hole 4 so that the air pressure in the system increases closing the valve 11. If the container is pressurised air from the hole 10 may be led away through a further flexible tube, and if the flow from a container is to be regulated the valve 11 is arranged to act in reverse manner, i.e. to open as the air pressure increases.

Title: Static pressure compensator system
IPC: G05D16/20
Filed: 1955-11-22
Abstract: 772,588. Measuring pressure. KOLLSMAN INSTRUMENT CORPORATION. Nov. 22, 1955 [June 15, 1955], No. 33408/55. Class 40 (1). [Also in Group XXXV] The pressure in a line 11 leading to the instruments operated by static pressure on an aircraft is automatically maintained at a value differing from that in the normal static pressure line 10 communicating with the outside of the craft by an amount which compensates for errors under varying flight conditions. As shown, the difference in pressure between the lines 10, 11 is measured by a barometric capsule which controls the position of a metallic armature 51 in relation to an inductive bridge supplied with 400-cycle current. The output of the bridge, which feeds a potential divider 57, thus represents the actual pressure difference. A computer device 30 gives a 400-cycle output which is a temperature-corrected function of the readings of instruments A, B, C, &c., measuring for example Mach number, altitude, airspeed, angle of attack, &c., and which represents the desired pressure difference. The difference between the two 400-cycle outputs (subject to the effect of the position of the slider of the potential divider) drives a reversible motor 21 coupled to a positive-displacement pump acting differentially with the aid of conduits 16, 17 separated by an apertured plate on the pressure lines 10, 11. When the pressure-difference is correct the motor stops. In a modification, Fig. 2 (not shown), the signals from the pressure gauge and the computer are applied to the amplifier valve in parallel instead of in series. If the motor fails, the line 11 acquires the pressure in the line 10.

[Class 38 (iii)] Non-regenerative braking.-A control system for a lift motor 1, 2, comprises means for inserting slowing down resistances 6, 7, 8 in the motor circuit, a generator 11 coupled to the motor, a variable resistance 16 connected across the generator, and a relay 14 which operates to prevent further variation of the motor or generator resistances when the generator speed falls to a predetermined value. The resistance 16 is varied in accordance with the generator speed to increase the load on the generator after the resistances 6, 7, 8 have been adjusted to their lowest speed values. The slowing down adjustment of the resistances may be initiated by movement of a controller to a slow speed position, or by operation of a ramp provided for floor finding purposes. The resistances 6, 7, 8 and 16 may be adjusted by solenoids, the circuit of one solenoid being connected by movement of the core of the other to the limit of its travel. In a modification, Fig. 2 (not shown), the generator 11 is compounded and supplies, through contacts of a relay connected across the generator, a pilot motor adjusting the resistance 16. In this arrangement the variation of the resistances 6, 7, 8 is not subject to the control of a relay responsive to generator voltage, and the connection of the resistance 16 and the pilot motor to the generator includes the contacts of a relay under the control of the controller. For final stoppage the controller is arranged to disconnect the motor and energize a relay which connects a resistance across the generator for dynamic braking. The separately excited fields of the generator and pilot motor are energized from the supply through a rectifier. Specification 172,122, [Class 38 (iii)], is referred to.

Abstract: 1485301 Flow control in fluidized bed electrodes PAREL SA 1 Aug 1974 [3 Aug 1973 (2) 14 Dec 1973 (3) 24 May 1974] 34077/74 Heading C7B  Particle movement in a fluidized bed electrode located on one side of an ion-permeable separator 4 in a divided cell 1 is controlled such that a region 16 of relatively low particle density exists e.g. adjacent the separator, while a region 15 of relatively high density exists e.g. remote therefrom. As shown, separator 4 is inclined upwardly towards the bed and electrolyte flow contributes to forming the regions by flow as shown. Flow directors, which may include provision of a corrugated separator, may promote the required flow. The outer wall 2 of the particle enclosing compartment may be parallel to or slope at a greater angle than the separator. The current distributer 17 may comprise one or more rods extending into the bed, or be a metal plateÀembedded in wall 2. The cell is useful in electrowinning e.g. Au,.Ag, Cu, Fe, Pt group, Co, Zn, Ni or Mn and the particles, of size 100-3000 Á, may be of the same or a different  metal e.g. Cu particles for receiving Cu, Ni or Co deposits. As metal deposits form, the enlarged particles may be removed: A sulphate or chloride (optionally acidic) electrolyte is useful. The second compartment 3 may be a duplicate of the first and may be provided with the pressure balancing means of Specification 1483464. A plurality of the particulate compartments may be vertically stacked. The separator, which may have ion-exchange properties, may be of a synthetic plastics or a ceramic and have a porous strengthening backing. The counter-electrode (usually anodic) may be inert or soluble, e.g. Pt on Ti mesh or a soluble particulate anode of Ni/Cu sulphur matte. The separator and/or counter-electrode may be arranged so that turbulent regions in the particulate bed are electro-chemically inactive. The fluidizing distributer 12 may have an open helical coil structure which is closed when required.
