Title: Improvements in or relating to apparatus for converting an electrical impulse or a series of periodic electrical impulses into a continuous pneumatic signal
IPC: G07C3/12
Filed: 1959-02-18
Abstract: 866,696. Fluid-pressure servomotor control systems. UNION CARBIDE CORPORATION. Feb. 18, 1959 [Feb. 19, 1958], No. 5555/59. Class 135. An electric to pneumatic analogue converter has two modes of operation; in the first the pneumatic output signal continuously reflects the peak value of each of a series of electrical input pulses and in the second the pneumatic output signal continuously reflects the sum of the peak values of a desired number of electrical input pulses. The input pulses cause rotation of a servomotor 2, Fig. 1, connected through gears 8 and 10 to the driving element 18, Fig. 2, of a magnetic clutch the driven element 28 of which is connected to a gear 30 having a pinion 32 which drives a gear segment 36 mounted on a shaft 38 which operates the control arm 41 of a pressure regulator 42 the output of which is a function of the position of the arm. A spring 34 interconnects the clutch parts 18, 28 the latter having a radially extending pin 14 which co-operates as described later with a pin 16 on the gear 30. The regulator 42 is connected to a cut-off valve 52, a rectriction 54, a solenoid operated valve 56 and a tank 50, the arrangement being such that on operation of the valve 56 the pressure in the tank 50 rises or falls to equal that of the output from the regulator 42. The tank is connected to a recorder and controller. A zeroizing motor 44 is connected through a pinion 46 to the gear 30. There are five cam-controlled programme switches S 1-S5 ; switch S1 is a sampling switch which conditions the servomotor 2 to follow an input signal on lines 4 and 6; switch S2 controls the magnetic clutch; switch S3 controls the solenoid valve 56; switch S4 controls the zeroizing motor 44 the circuit of which is interrupted by the switch S5 actuated by the gear sector 36. In the first mode of operation the pin 14 is screwed inwardly to lock the driven element 28 to the shaft 12, the zerozing motor 44 and the solenoid-operated valve 56 are activated after each pulse so that the output signal continuously reflects the peak value of each pulse. In the second mode of operation the driven element 28 is free on the shaft 12 so that the spring 34 brings the pins 14, 16 into abutment before the reception of each pulse of the series, the zeroizing motor and the solenoid operated valve 56 are activated after the reception of the desired number of pulses so that the pneumatic output signal continuously reflects the sum of the peak values of the input pulses. The apparatus may be used for sampling the readings of one or more monitoring instruments, e.g. in a continuous gas analysis.

Title: Improvements in mechanism for operating elevator doors
IPC: B66B13/08
Filed: 1931-02-24
Abstract: 368,958. Lifts. WAYGOOD-OTIS, Ltd., 54, Fetter Lane, London.-(Otis Elevator Co. ; 260, 11th Avenue, New York, U.S.A.) Feb. 24, 1931, No. 5773. [Class 78 (iii).] Electric motor driven operating mechanism for lift car and landing gates is adapted to open'the gates with a slow initial and final movement and a quick intermediate movement, the gates 'being closed by springs and the landing gate operating member reacting against the shaft guides to avoid backlash. The car 14 carries an electric motor 16 which has separate connections for operating the car and landing gates. The car gate 20 is operated by a lever 50 carried by a shaft 52 and having an extension 53 connected to a dashpot 55 and an extension 54 connected by a chain 56 to an eccentric drum 58 on the main shaft 34, the drum giving a slow initial and final and a quick intermediate movement. The gate is closed by a spring 62 connected by a chain 64 to an arm 66, Fig. 9, having a hub mounted on the shaft 52 and engageable by a lug 68 with a lug 70 on the shaft 52. The hub also has a radial projection 72 engageable by a latch 74 to prevent the gate when opened being closed by the spring 62. The landing gates 22, Fig. 5, are operated by toggle linkage 82 connected to a bent lever 80, projecting into the well and operated by a cam on the car. The linkage is also connected to a dashpot 92 for checking the movement of the door and fitted also with a spring 90 for closing the door. The bent lever 80, Fig. 2, is acted on by a linkage cam 96 on the car acting at right-angles to the well guide. The cam is raised to open the gate by a chain 102 connected to an eccentric drum on the main shaft and acting like the drum 58. A pedal 106 in the car can be operated to release a clutch on the main shaft to disconnect the motor through a chain 108, Fig. 10, and thus lowers the latch 74 to keep the spring 62 from closing the gate 20. To open the motor circuit when the gates are at the end of their movement the main shaft 34, Fig. 12, carries a disc 120 with adjustable plates 121 carrying lugs 123 engaging pivoted levers 125 controlling the circuit breakers 127. In operation, when the hoisting controller is moved to neutral, the motor is energized by means of relay and solenoid mechanism and the main shaft 34 is rotated to wind up the chains 56, 102 thus opening the car gate directly and the landing gate through the cam 96. When the rotation of the motor is reversed the springs 62, 90 are released and the gates are closed by the springs. If the power supply fails, the landing doors may be closed by the spring 90 by releasing the clutch by the pedal 106.

Title: Improvements in or relating to separators for liquids having different specific gravities
IPC: B01D17/02
Filed: 1938-02-24
Abstract: 511,856. Gravity-separation apparatus. THOMSON, H. A. Feb. 24, 1938, No. 5888. Addition to 419,712. [Class 46] In apparatus for separating liquids of differet specific gravities, as described in the parent Specification and comprisng a number of quiescence chambers of ovate vertical crosssection and a dome or chamber in which one of separated liquids collects for discharge through a valve controlled by a lever turned by a float, a pilot float is provided to ensure that the main float shall always follow the separation level between the separated liquid and the flow liquid despite changes in the specific gravity of the latter. The apparatus is shown in Fig. 1 as applied in the separation of light oil from water. The float 12, which controls the outlet valve 8 for oil, is attached to a lever 10 turning on a fulcrum 11 and is counter-balanced by a pilot float 13 attached to the other end of the lever. The float 13 is weighted so that it overcomes the float 12 when both are immersed in the same liquid. When the float 12 is immersed in an upper layer of oil the lever is turned to open the valve 8 and the oil is discharged. Fig. 5 shows modified apparatus in which the floats are attached to separate levers 10<1>, 10", connected by a link 14. In this form of apparatus the collecting chamber 2 is recessed into the body 1 of the separator. Fig. 6 shows a further modification in which the float 13 and part of the lever 10 are in the body of the separator. When the apparatus is adapted for the collection of a liquid heavier than the main body of the mixture, the pilot float is made lighter than the main float.

Filed: 1969-02-04
Abstract: 1,221,621. Centrifugal separators; nozzles. SIEMENS A.G. 4 Feb., 1969 [13 March, 1968], No. 6017/69. Headings B2F and B2P. A vortex flow separator for separating a constituent from a flowable medium having constituents of different specific gravities comprises a vortex chamber 1, an inlet pipe 2 for the medium, an outlet 3 for the constituentfree medium, auxiliary gas inlets 4 opening obliquely into the chamber opposite to the direction of flow of the incoming medium for stimulating in the chamber a helical flow system in the form of an external helical potential flow and an inner helical rotary flow circulating in the same sense but with opposite axial flow components, an outlet gap 6 for the separated constituent surrounding the inlet pipe 2, a spraying nozzle 9 for producing a conical curtain of liquid extending away from the inlet pipe and one of more tangential inlet openings 20 in the upper half of the chamber for introducing a liquid to wet the inner wall of the vortex chamber. The conical curtain of liquid causes the particles of the constituent to be separated to agglomerate whereas the wetting liquid allows them to be removed from the chamber without contacting the wall thereof. A shield 8 is provided on the inlet pipe 8 to provide a relatively narrow annular gap to improve separation. The spraying nozzle 9 comprises a tubular outer casing 10 having a conically widening aperture 11 and a liquid supply union 12 closed at its upper end and connected at its lower end to a supply conduit 16, the interior of the union communicating with the interior of the casing by way of radial apertures 13. The union 12 is sealed to the casing 10 by a sealing ring 18 at the lower end of the casing and carries a cap portion 14. The casing 10 is connected to the union 12 by means of a screwthread 15 so that the nozzle aperture size can be adjusted by means of the cap portion 14 by axial displacement of the casing. Vanes 19 are provided in the mouth region 5 of the inlet pipe 2 to impart a pre-spin to the entering medium. To prevent particles of the constituent to be separated from accumulating on to the vanes, the latter are sprayed with part of the liquid supplied through the conduit 16 and fed via radial bores in the union 12 to means 17 having outlet apertures. Alternatively, the vanes are made hollow at their lower regions and liquid issues from apertures at these regions. The separator may be used for the separation of (a) adhesive liquids, e.g. paint sprays or oils, from a gaseous carrier medium; (b) dust from gases; (c) oil-water mixtures; (d) readily evaporating liquids from liquids which evaporate with more difficulty.
