Title: Blanking Circuits for Television Receivers
IPC: H04N3/24
Filed: 1967-04-11
Abstract: 1,180,141. Cathode-ray tube circuits. R.C.A. CORP. 11 April, 1967 [18 April, 1966], No. 16653/67. Heading H4T. Pulses derived from the scan generators of a television receiver during retrace intervals and supplied to a video amplifier stage to produce blanking pulses for the tube beam are also utilized to render non-conducting a diode supplying the video signals to the video amplifier stage. With this arrangement the pulses derived from the scan generators may be applied to a point in the receiver circuit which has a lowimpedance to ground, e.g. to the control electrode of a video amplifier stage in a colour television receiver which is driven by a lowimpedance delay line, without the scan generators being designed to supply the power otherwise required or without the need for an additional amplifier stage and without adversely affecting the operation of circuits preceding the point of application. Thus, in Fig. 1, which shows the circuit of a colour television receiver, although the invention is applicable to monochrome (black-white) systems, the video signal derived via diode 20 which detects the negative envelope of the composite video signal, is supplied via a first video amplifier 22 to a delay line 46 (which compensates for the inherent delay in the chrominance circuits) and thence via a diode 86 forwardly biased by source V 3 , to a second video amplifier 26. During retrace intervals a negative pulse derived from the vertical deflection circuit 36 overcomes the forward bias on diode 86 which is thereby rendered non-conducting to isolate the preceding circuitry and the pulse is then effective via video amplifier 26 to produce a positive blanking pulse for the cathode of the picture tube 28. For horizontal retrace blanking a pulse derived from the horizontal deflection circuit 38 is supplied via a pulse amplifier, capacitor and resistor to the junction of resistors 92 and 94 (Fig. 3, not shown).

Title: Improvements in or relating to a liquid pouring installation
IPC: C02F1/68
Filed: 1967-04-13
Abstract: 1,125,698. Electric correspondence control systems. CENTRE DE RECHERCHES DE PONT -A. MOUSSON. April 13, 1967 [April 22, 1966], No. 16963/67. Heading G1N. [Also in Divisions F1 and G3] Pouring of a liquid L (Fig. 1) from a container A1 is controlled by regulating the gas pressure in the space above the liquid in the main part of the container via a valve 11 and entry aperture 7, the pressure being initially increased so that the liquid in the spout 1 is at the level N of the lip, adding a step increase in pressure to obtain a desired rate of pour, then increasing the pressure in inverse relationship to the weight of the assembly as measured at 13 to maintain the rate of flow. The weight signal at 13 is inverted at 14 and fed to a comparator 17, together with a signal from a pressure transducer 12, the combination producing an output signal which adjusts valve 11 so that the liquid in the spout 1 is at level N. Pouring is initiated by closing a switch 19a, e.g. a photoelectric switch operated by the presence of a mould, which adds a step voltage from control device 16 to comparator 17, whereupon the internal pressure is increased, and the liquid 2 overflows from spout 1. The rate of pouring, determined by the magnitude of the step voltage from 16, is maintained constant by varying the applied pressure in an inverse relationship to the change in weight sensed at 13. Pouring ceases when switch 19a is reopened. The container A1 may be refilled at any time during the operation, because of the automatic link between weight and pressure. In a modification Fig. 4 (not shown), the outflowing liquid passes through a detached length of conduit which is continuously weighed to determine the rate of flow, and this measurement is used to control the signal from control device 16 to obtain a desired rate of flow.

Abstract: 205,537. Mitchell, E. A. June 21, 1922. Branches and mains, connecting; with valves. -In connecting branches to mains under pressure by permanently securing a saddle-piece, carrying the branch pipe, to the main and drilling the latter by means of a drill passed down through the branch and a plug valve provided therein, the joint is made fluid tight by lining the aligned holes through the saddle piece and main with a tightly-fitting ferrule of cylindrical or taper shape and externally either plain or screw threaded. A saddle-piece a, with branches b<1>, b<2> and a horizontal plug c, ported at c<1>, is secured to the main pipe d by U-shaped bolts e, a layer d<1> of packing material being inserted between them. A drill f is inserted through a stuffing-box g screwed to the branch b<1>, the plug opened and a hole drilled through the saddle-piece and main. The saddle-piece may be initially drilled, but with a hole of smaller diameter than the drill to be used. The drill f is withdrawn into the branch b<1>, the plug closed, and the stuffing-box and drill removed. A ferrule m is dropped into the branch b<1> and the stuffing-box g and a plunger secured. The plug c is opened, allowing the ferrule to drop and the latter is forced into position, as in Fig. 4, by means of the plunger. In the case of a screwed ferrule, the drill is replaced by a screw tap, which screws the aligned holes preferably in taper shape. The ferrule m is inserted as before and screwed into position by means of a tool adapted to engage it, as by notches m<1>, Fig. 5. The service pipe is finally attached to the branch b by a screwed sleeve. The saddle-piece and stopcoek casing may be a single casting or in separate parts connected, for example, by a stuffing-box joint. The stopcook casing b<3> may be internally threaded to receive a stuffing-box n for the plug spindle c<2> and externally threaded to receive a screw cap, packed if necessary, to protect the outer end of the spindle.
