Abstract: 1370588 Acoustic flow meter WESTING- HOUSE ELECTRIC CORP 19 Feb 1973 [1 March 1972] 8052/73 Heading H4D [Also in Division G4] The flow velocity of a liquid 20 relative to two transducers 11, 12 is measured by simultaneously transmitting an acoustic signal from each transducer, measuring the time delay before receipt of the signal at each transducer and calculating the flow velocity from the elapsed time by digital programmable means. The time measurement device 16 comprises two elapsed time counters and a source of clock pulses. Transmission of the acoustic signal from 13 initiates the feeding of clock pulses to a first counter. This count is stopped and a pulse feed to the second counter started on receipt of a signal from either receiver A or B. The count in the second counter is stopped on receipt of a signal from the other receiver. The counter readings then represent the elapsed times. The digital processor comprises a preprocessor, a programming unit and an arithmetic unit. Its caldilation and function can be altered by changing plug-in modules and it includes self checking apparatus and means for checking that the elapsed time signals fall within a predetermined time span. The apparatus may comprise several transducers which can be selectively grouped in pairs for measurement. The output display may indicate flow velocity, flow direction and mass flow rate.

IPC: H03K19/173
Filed: 1959-03-10
Abstract: 912,383. Pulse generating circuits. FERRANTI Ltd. March 9, 1960 [March 10, 1959], No. 8152/59. Class 40 (6). A circuit which delivers an output pulse coincident with a clock pulse only when it is preceded by an input pulse exceeding a predetermined amplitude or a plurality of simultaneous input pulses equivalent to a single pulse which exceeds said predetermined magnitude comprises a transformer having a plurality of primary windings 11, 12, 13 to which the input pulses are applied, a secondary winding 14a associated with a capacitance 15 and a resistance 32 to provide a half-criticallydamped resonant circuit, the resonant circuit being connected in series with the clock-pulse source 17 in the input circuit of a normally non-conductive amplifying device such as a transistor 16, the amplitudes and polarities of the input and clock pulses being so chosen that the initial half-cycle of oscillation produced in the resonant circuit on the application of an input pulse is in a sense to maintain the amplifying device non-conducting but the overswing which follows is of sufficient amplitude when a clock pulse is supplied simultaneously to cause the device to conduct and current to flow through load 26 which may be the input winding of a similar stage. In the circuit illustrated a constant current flows through the resistor 21 so that the current through the transistor 16 when it conducts is determined by the resistor 21. The damping resistor 32 is coupled in parallel with the tuned circuit 14a, 15 through a further secondary winding 31. Diodes 33, 34 are provided to limit the initial voltage swing across the tuned circuit so the voltage overswing, even with a plurality of simultaneous input pulses, cannot be large enough to cause the transistor to conduct except during a clock pulse. Secondary winding 14a is one half of a centre-tapped winding, the other half-winding 14b being connected through a neutralizing capacitor 23 to the collector of transistor 16 to neutralize the collector-base capacitance. A further winding 27 provides feed-back to neutralize hole-storage currents which flow in the base circuit when the transistor is switched. It is stated that the winding 31 may be omitted with the resistor 32 connected directly across the resonant circuit. In this case, however, the limiting diodes are returned to bias-potential sources to which pulses are applied in synchronizm with the clock pulses. Further the transistor may be replaced by a discharge tube such as a pentode valve and the capacitor omitted, the winding 14a being tuned by its own self-capacitance. Specification 846,267 is referred to.

Abstract: 630,510. Hinges. WELDALL & ASSEMBLY, Ltd., and LIGHTBOURNE, R. C. March 26, 1947, No. 8186. [Class 65 (ii)] [Also in Group XI] A closure device for the grill chamber of a cooking stove or the like comprises a flap 1 pivotally mounted intermediate the top and bottom edges on a slide member or members 2, which is or are constrained to move outwardly and horizontally by a guide or guides 3 to permit the flap to move from the closed to the open position against the tension of a spring or springs 4. The flap is retained in the open position by the engagement of its lower edge with a part 7 of the frame of grill chamber. When the flap is pulled outwardly and downwardly by means of handle 5 it fulcrums about its lower edge on part 7 of the grill chamber frame and pulls outwardly the slide member or members 2 against the tension of the spring or springs 4. At the same time the flap will pivot on the slide member or members thus causing the bottom of the flap to ride upwardly on the point of the fulcrum until it is in a horizontal position when the spring controlled member or members will pull the bottom edge of the flap against the frame member 7 and thus hold it in this position.

Abstract: 549,338. Gas washers. TRAUGHBER FILTER CO., Ltd., and MODE; W. F. July 1, 1941, No. 8286. [Class 55 (ii)] In apparatus for the removal of fine particles from gases by a washing liquid in which the liquid is maintained in troughs through which the gases are passed and which are covered by bells or channels which force the gases below the level of the liquid, an overflow being maintained which will remove froth from the surface of the liquid, the washing liquid is continuously removed from near the bottom of the liquid. The gas is admitted through an inlet 1, which directs it downwardly against a body of liquid 2, and passes through a spray from a rotating drum 4 before faking a tortuous path leading through another spray from a rotating drum 8. The gas then passes upwards and is forced by inverted channel members 11 through the liquid in troughs 10 after which it traverses a fine rain or liquid falling from a bed of Raschig rings sprayed by nozzles 15. A further layer 18 of Rasehig rings are sprayed.by pipes 19 when desired, but may be used to dry the gases before they pass to the outlet 21. The continuous discharge of the liquid from the floors of the troughs 10 is effected through drain openings 22 connected to common headers 23 leading to outside the tower, and to discharge pipes 26, the quantity and state of the liquid being -easily observed as it discharges into funnels 25. The volume of liquid discharged in a given time is equal to the volume supplied less that overflowing from the surface, and controlled by an adjustable weir 29. The rate of supply of liquid to the header 16 is such that there is a continuous discharge through pipe 31 thus keeping the pipes 15 free from deposited solids. Specification 485,155 is 'referred to.
