Title: Capacity control operating mechanism for centrifugal compressor
IPC: F04D29/46
Filed: 1971-06-24
Abstract: 1356855 Centrifugal compressors CARRIER CORP 24 June 1971 [3 Aug 1970] 29741/71 Heading F1C [Also in Division F2] A mechanism for actuating centrifugal compressor control means, e.g. an inlet valve 23, Fig.1, or a discharge diffuser valve, comprises a constant speed reversible motor 50 for adjusting the valve through a linkage 37, 35, 31 which causes the valve to move more slowly as it approaches its closed position. Power shaft 51 is driven by the motor through gear-box 45 and carries a radial arm 37 which receives a pin 36 projecting from a block 35 slidably located on a radial arm 31 attached to valve shaft 30. As the valve 23 is moved towards its closed position, the block 35 slides along arm 31 towards shaft 30 thereby causing a gradual decrease in the transmission of angular movement from arm 37 to arm 31. The range of angular movement of arms 31, 37 is controlled by limit switches (60, 61), Fig.2 (not shown). The motor is controlled by means sensing the demanded compressor load.

Title: Improvements in or relating to circuits for cathode-ray oscilloscopes
IPC: G01R13/30
Filed: 1946-10-05
Abstract: 620,851. Cathode-ray oscillographs. PHILIPS LAMPS, Ltd. Oct. 5, 1946, No. 29748. Convention date, March 16, 1943. [Class 37] The amplitude of a cathode-ray tube trace is measured by producing a cursor or datum trace whose position is adjustable to coincide with a peak of the trace to be measured, a calibrating voltage then being substituted for that producing the trace to be measured and being adjusted to be coincident with the datum trace. In one embodiment, the signal to be measured is applied at 3, Fig. 1, over switch 13 and amplifier 2 to an electronic switch 9 controlled by pulse generator 10; an adjustable direct potential 7 is applied to the switch 9, so that the signal 4 is displayed on the cathode-ray tube alternately with a datum dot or line 6 which is adjusted to the peak of signal 4; switch 13 is then changed and the signal replaced by an oscillation from 14 adjusted to be of approximately the same frequency and to have its peak at the datum 6; the signal at 3 then has a peak voltage equal to that developed at 4. In a further modification, the amplifier 2 is applied to one deflecting system and the datum signal from 7 is applied to another deflecting system of a tube having two complete deflecting systems, Fig. 2, not shown. The voltage from 7 may be alternating with a frequency ten times greater or ten times less than the time-base frequency. The Specification as open to inspection under Sect. 91 includes the case where the source 14 is used in place of source 7, Fig. 2 (Cancelled). This subject-matter does not appear in the Specification as accepted.

Title: Record card transferring apparatus
IPC: G06K13/04
Filed: 1958-09-18
Abstract: 878,526. Statistical apparatus. MAGNAVOX CO. Sept. 18, 1958, No. 29914/58. Class 106 (1). [Also in Group XVI] In a statistical machine, record cards are transferred from a feeding means to another means e.g. a second feeding means or a receptacle, by applying fluid pressure against the cards without relaxing the holding force on the cards by the feeding means. The record cards have information thereon in the form of perforations, magnetic areas, &c. As shown in Figs. 1 and 4, two suction drums 10, 12 of similar construction are rotatably mounted above a table 17, are driven continuously by belts arranged below the table, and are always connected to a vacuum pump. The drum 10 comprises a bottom plate 19, to which are secured by studs 28, top and bottom rim portions 42, 45 and a pair of rings 30 which are spaced apart to provide peripheral suction slots 36. The top of the drum is covered by a fixed cylindrical plate 14, supported from the table 17 by brackets 15, and which supports a number of compressed-air feed lines 92 carrying nozzle housings 100 arranged within the drum. The feed lines 92 lead from a conduit 90 connected to a source of compressed air through a solenoidoperated valve 86. In operation, record cards gripped on the periphery of the drum 10 by suction are fed past a transducer 112 which reads the cards and controls the valve 86, and if a particular card is to be transferred from the drum 10 to the drum 12, the valve 86 is opened, and the blasts of compressed air from the housings 100 pass through the peripheral slots 36 to force the card away from the drum 10 so that it can be grasped by suction to the periphery of the drum 12. Record cards may be transferred to the drum 10 from an input magazine and delivered by the drum to a stacking magazine as described in Specification 845,490, or they may be transferred to the drum 10 from another drum; or they may be transferred from the drum 12 to the drum 10 by compressed-air means, as described above, on the drum 12, under the control of a transducer 114. Cards on the drum 12 may be transferred to a third suction drum or to a stacking magazine. In a modification, Fig. 5, the suction drums 200, 202 are constructed similar to the drums 10, 12 described, except that the record cards are transferred from one drum to the other by a blast of compressed air from an external housing 210 directed tangentially to the drum 10 to overcome the suction force exerted on the cards by that drum.

Filed: 1974-07-09
Abstract: 1479671 Controlling electrolysis PPG INDUSTRIES Inc 9 July 1974 [10 July 1973] 30279/74 Heading C7B Electrolysis e.g. of NaCl to yield NaOH and Cl 2  is conducted in a plurality of flowing mercury amalgam cathode cells in series, each having a plurality of vertically movable anodes in anode rows in vertically movable anode banks, by discretely measuring each of the individual current flows through the anode rows of a single cell at intervals sufficient to detect and respond to incipient changes therein by generating individual first electrical signals proportional to each of the individual current flows and transmitting each first signal to a common control element, generating a second electrical signal proportional to the average of the individual current flows through the anode rows, e.g. by measuring the total current flow to the cell and dividing the signal generated therefrom by the number of first signals, and generating individual anode row error signals proportional to the difference between the individual first signals and the second signal and moving vertically individual anode rows in response to corresponding anode row error signals to maintain the individual current flows within a pre-set range of the average of the individual current flows through the anode rows of a cell. Additionally, a set point or control signal proportional to the current corresponding to an incipient short circuit condition is transmitted to the common control element and a short circuit condition error signal is generated when a first signal exceeds the set point or control signal, all the anode rows being moved vertically away from the cathode in response to this error signal; the individual voltage drops between the anode rows and the cathode are discretely measured as third signals and individually transmitted to the common control element at the same time as the corresponding first signal and with a signal corresponding to a minimum cell voltage, a fourth signal proportional to the average of the individual voltage drops between the anode rows and the cathode and an adjustment signal proportional to the difference between the fourth and minimum voltage signals are generated, all the anode rows being moved vertically towards the cathode in response to this adjustment signal. A relay matrix output may be controlled through the common control element, actuating contact closures, preferably arranged in an equal number of columns and rows, to activate a latching relay matrix, e.g. closing a contact in a row and a contact in a column to latch closed a relay at the intersection, and closing a contact in a row only to latch open all the relays in the row. The cells may be thus controlled sequentially or randomly.

Abstract: 1,014,636. Starting prime movers. ROLLS-ROYCE Ltd. July 24, 1964 [July 31, 1963], No. 30463/63. Heading H2H. [Also in Division F1] In a locomotive power plant comprising engines 11-14, Fig. 2, a selector device 16 ensures that the engines are started in a predetermined sequence. A starter circuit 19 is controlled by a manual button 20 and is connected to sets of contacts 18 co-operating with angularly spaced sets of contactors 17 on a rotatable drum 16 which is stepped around by an electric motor 72, the drum co-operating with sets of contact brushes 18<SP>1</SP> connected to the engine igniters and starter motors. In the initial position shown in Fig. 2, with contacts 18 opposite the first set of contactors 17, depression of button 20 completes the starting circuit to engine 11. When the engine is at operating speed, a generator thereon energizes solenoids 30, 50 to close switches 36, 54. Switch 54 closes a circuit from line 90 through contactor 80 on the drum and via brush 74 and line 60 to energize solenoid 66 to close switch 70, whereby motor 72 is momentarily energized to rotate drum 16, the circuit being broken as soon as contactor 80 moves away from contact 84. The inertia of the drum moves it around 90 degrees until contactor 81 reaches contact 85. When button 20 is again depressed, the second set of contacts 17 closes the starter circuit of engine 12 and the drum is stepped around a further 90 degrees by closing of solenoids 31, 51. Engines 13, 14 are started in sequence upon successive operations of button 20, but further stepping around of the drum 16 after engine 14 has restarted is prevented by circuit 40, in which all the switches 34-37 are by then closed, which energizes solenoid 41 to open switch 65 and prevent closing of the circuit of motor 72. After the plant has been shut down, the engines re-start in the sequence 14, 11, 12, 13, i.e. the plant restarts on a different engine each time so that wear on the engines is evened out. In a modification, Fig. 4, switches 104 for each engine arranged at 90 degrees intervals are closed in sequence by a cam 110 which is stepped around by. a pawl and ratchet device 115, 113, actuated by a rack 119 which is reciprocated by fluid pressure at each engine starting, the rack being moved in one direction when the starter button is operated and moved back in the opposite direction when the associated engine reaches operative speed.
