Filed: 1971-04-19
Abstract: 1317348 Venturi scrubbers for gases CHARBONNAGES DE FRANCE 19 April 1971 [8 April 1970] 26181/71 Heading B1R Gas to be dedusted flowing in direction F passes to and through venturi section 4 of a gas scrubber, water being sprayed into the stream through spray 15 located in the neck of the venturi. The wet gas stream leaving the venturi passes over conical deflector 6 which is provided with means which impart a rotational component to the gas flow. Liquid outlet 22 in gas-liquid separation section 8 is tangentially located, but in the opposite sense to the direction of rotation of the gas stream (see Fig. 2, not shown). The interior of separation section 8 may be rough, e.g. by providing an inner lining of expanded metal. The apex angles of sections 3 and 5 of the unit are both suitably 90 and the cross-sectional area of flow at the base of conical deflector 6 is preferably at least that at the apex.

Title: Monitoring apparatus
IPC: G01R19/145
Filed: 1975-06-20
Abstract: 1475024 Measuring voltage FORD MOTOR CO Ltd 20 June 1975 26246/75 Heading G1U For monitoring the value of a parameter, a transducer provides a signal representing the parameter, two comparators provide three output states indicating the value of the signal with respect to two reference levels and an indicator is activated continuously by one output state and intermit tently activated by a second output state via a pulse generator. In the motor vehicle engine coolant warning system described, a thermistor sender unit 10 is in series with a resistor 22 across a Zener diode 18 stabilized voltage, the voltage across the thermistor provides current to current comparators 26, 24 having reference currents derived via resistors 28, 30. As the coolant temperature is initially low (i.e. high thermistor resistance) both comparators have high outputs that from 24 turns on transistor 36 to illuminate lamp 12, or sound an audible alarm. As the temperature rises, the current via resistor 44 falls, and at a predetermined temperature, the comparator 24 output goes low, turning off transistor 36 and the lamp 12 is extinguished indicating normal engine temperature. If the temperature exceeds a permitted level, the comparator 26 output goes low, enabling a pulse generator 38, whose output pulse train adjusted by resistor 50 and capacitor 52, causes the lamp to flash via transistor 36.

[Class 119] Relates to cocking and ejecting mechanism for double-barrelled drop-down sporting guns having slidable hammers 9 each cocked by a cam 14 engaging a forward extension of the hammer. According to the invention, each extension engages by a roller 15 with a cocking cam 14 pivoted at 17 on a block 8 pivoted on the barrel hinge 2 to move with the barrel. Further, the cam 14 includes two bevelled faces 14a, 14b selectively engaging faces x, y on the block 8. During breaking of the gun after firing, the face x engages the face 14b and the cam only projects sufficiently to cock the hammer partially and allow the hammer spring to react on an ejector lever 16 moving on the pivot 17. During closing of the gun, the face y engages the face 14a, as shown, to cock the hammer fully on to the sear 11. If the gun is then opened without having been fired, the ejector lever is operated by the fixed member 19 to give a shortened movement to the sliding ejector 18 to permit of hand extraction of the live cartridge. The Specification as open to inspection under Sect. 91 also describes (1) replaceable bushes for the barrel joint pin; (2) a sliding rear barrel lock operated by a swinging finger lever on the top of the stock and (3) a front barrel-locking catch which is readily releasable.

Filed: 1955-09-15
Abstract: 781,740. Flame detectors. SPECIALTIES DEVELOPMENT CORPORATION. Sept. 15, 1955, No. 26416/55. Class 40 (3). In apparatus for detecting flames in which a detector produces an output modulated in accordance with the flicker frequency which frequencies are selected by a band-pass circuit, in order to discriminate against other flickering light sources, the change in the flicker frequency is detected by means of a frequency modulation detector. Thus (Fig. 2) infra-red radiation detector which may be a bolometeton tube or lead sulphide cell responds to the flame and a band of frequencies commonly produced by flickering flames, for example 5 to 30 cycles per second, is selected by a band-pass amplifier also containing an amplitude limiter. Thus a constant amplitude input is fed to a frequency discriminator Which detects variation in the fundamental flicker frequency and produces a signal in response to a given frequency of variation. The output of the discriminator controls a thyratron and electromagnetic relay to operate an indicator.
