Title: Device for co-dispensing two materials under pressure
IPC: B65D83/14
Filed: 1971-05-21
Abstract: 1345547 Pressurized dispensing containers P MESHBERG 21 May 1971 [3 Sept 1970] 16344/71 Heading F1R A pressurized dispensing container comprises inner and outer containers 10, 11 respectively, each provided with a valve 12, 20 having a reciprocable valve stem 13, 29, the valves and the inner container 10 being located by a connector 24. In the embodiment of Fig. 2, on depression of a button 41, the stem 29 of the outer container valve 20 depresses the stem 13 so that product M 2  from the outer container can pass through dip tube 33, bore 34, passage 35 and a port 36 in the stem 13, to mix with product M 1  from the inner container flowing through a second port 17 in the stem 13. The mixture is discharged through passages 37, port 42 and passages 38, 39, 40. The spacing of the ports 42, 36, 17 along the stems can be selected so that one valve opens before the other and closes after the other. A pressure relief valve 50 is provided for the outer container and comprises an outwardly spring-biased plug 51 and a flexible diaphragm 54 open to the interior of the outer container. In a second embodiment, Fig. 5, each valve is a metering valve and in the closed position of the dispenser shown, product from the inner container fills the metering chamber of the inner valve 112 while that from the outer container enters a metering chamber of the outer valve formed by a chamber 135c and passages 135a, 135b, by flowing through passage 135 and port 117, and passage 136 and port 1360. Initial depression of the upper stem depresses stem 113 to close the metering chamber of the inner valve; further depression allows product from the inner container to enter the metering chamber of the outer valve, through features 117, 116, 136 and 136a, and continued depression causes dispensing of the mixture. Axially directed cut outs (B 1 ), (B 2 ), (B 3 ), Fig. 7 (not shown), in the stems allow filling of the containers by providing paths which by-pass each of the valve seals,

Patent GB-626310-A (GB)
Title: Improvements in or relating to sub-aqueous pressure wave apparatus, for example to echo sounders
IPC: G01S7/529
Filed: 1946-05-29
Abstract: 626,310. Subaqueous audible and like signalling apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and TWATT, J. May 29, 1946, No. 16390. [Class 118 (ii)] [Also in Group XL (c)] An echo-sounder or like subaqueous pressure-wave apparatus comprises a mercury-vapour tube triggered into its conducting state on each transmitted pulse and having an auxiliary anode utilized to actuate a sensitivity or gain control circuit for the receiver. Closure of the switch SW triggers the mercury-vapour tube MV and causes a magnetostrictive transmitting device to emit a pulse as in Specification 626,309. At the same time the path between the auxiliary anode 6 and cathode 7 becomes conducting and allows a control condenser 8 to discharge. The potential across the potentiometer 11, 12 therefore drops and since the point P is connected to the control grids of amplifier valves 20, 21 of an associated receiver, the gain of the latter decreases. During the period before the emission of the next pulse the control condenser 8 gradually charges up to the potential of the battery 37 and the receiver gain rises correspondingly. Thus the gain increases with time and compensates for the attenuation of a received echo which similarly increases with time, i.e. with the range of the reflecting object. The lower portion 12 of the potentiometer 11, 12 is byepassed by a high-frequency de-coupling condenser 13 and the upper portion 11 may be shunted by a second condenser 41. In this case during the emission of a pulse the very rapid discharge of the control condenser 8 will cause the potential developed at the control point P to be decided by the ratio of the condensers 13, 41, rather than the resistors 11, 12, and the capacities may be so arranged that the output of the receiver is substantially suppressed during transmission. Over a limited range the above arrangements apply a gain correction proportional to the attenuation of the received echo. In order to extend the range over which such proportionality obtains, a more elaborate resistance-capacity network may be employed in the control condenser circuit. Alternatively or in addition a mercuryvapour tube may be employed with a plurality of auxiliary anodes, each having its own control condenser circuit of a different time constant and controlling the gain of a different amplifier valve. The control condenser 8 may be arranged to charge, instead of discharge, when the nercury-vapour tube MV is conducting. Specification 626,308 also is referred to.

Filed: 1948-06-18
Abstract: 645,317. Pulse delaying circuits. HUGHES & SON, Ltd., H., CROWN, W. H., and WHITFIELD, H. R. June 18, 1948, No. 16509. [Class 40 (vi)] A circuit for generating a short output pulse a predetermined time after the commencement of an input voltage variation comprises a pulse generator valve circuit which is normally inoperative and to which is applied a first voltage derived from the input voltage to render the generator operative at a predetermined time and a second voltage also derived from the input voltage which renders the generator inoperative after it has generated a single output pulse. In the Figure, valve V1 is connected in a blocking oscillator circuit to generate narrow pulses having a repetition rate which is considerably higher than the input voltage variations which are applied at terminal 8. Valve V1 is normally cut-off by the bias voltage at the junction of resistors 16, 17. The positive going input voltage variation is applied to valve V2 which has both anode and cathode circuit loads. The values of the cathode coupling circuit 15, 5 are such that a predetermined time after the commencement of the input voltage variation valve V1 is rendered operative. The anode coupling circuit 13, 14 is such that after the valve V1 has generated a single output pulse the valve is cut-off at the suppressor grid and oscillations cease until the next input voltage variation commences.

An arrangement for coupling together slide magazines comprises a magazine guide and two pinions coupled together for synchronous rotation and arranged so that between them they can engage the racks of two magazines. In the embodiment shown in Fig. 1, pinions 7, 18 are coupled together by a chain 11 and the shaft 13 on which pinion 18 is mounted is fixed to a lever 14 which is pivoted on the shaft 8 of the pinion 7 so that lever 14 can be moved against a spring 15 and the pinion 18 can be temporarily moved out of the magazine guide 2 while magazines 3, 3a are inserted. Instead of the lever 14, the pinion 18 may be coupled to the pinion 7 by means including a ratchet and pawl arranged so that any rotation of pinion 18 caused by the insertion of a magazine is not transmitted to the pinion 8. Alternatively, the two pinions may be arranged close together and connected by a gear-wheel which can be moved to uncouple them as requested. The pinions may also be coupled by a rack or by two gear-wheels joined by rods and each engaging a pinion.
