Title: Lifeboat for submarines and other vessels
IPC: B63G8/41
Filed: 1925-01-19
Abstract: 249,258. Vincent, J. H. Jan. 19, 1925. Lifesaving chambers and the like; sunken objects, indicating position of.-Lifesaving apparatus for submarine vessels comprises a lifeboat 1 located in a recess 2 arranged on the exterior of the submarine and enclosed by a cover 3 which terminates in a flange to which is secured a circumferential, channel-section member bedding on a strip of rubber 5 fitted round the edge of the compartment 2 in which the boat is located. The flange is pressed hard against the rubber strip to make a water-tight joint by the action of a number of wedging-bolts 8 which engage the underside of the top 6 of the compartment 2 and are simultaneously operated by a fore and aft shaft carrying a series of cams with which the inner ends of the bolts engage. A buoy 19 secured to a length of tubing 20 is located in the compartment 2 and is released with the boat and thus serves to locate the position of or to deliver air to the submerged vessel.

Abstract: 632,198. Tubular heat-exchangers. HOWLETT, E. J., GLEDHILL, H., GLEDHILL, N. R., and GLEDHILL, M., (trading as THOMAS'S). Jan. 16, 1947, No. 1542. Addition to 597,611. [Class 64(iii)] In a heat-exchanger for heating the incoming process water for laundries &c. from the waste water, and for use in other cases in which at least one of the liquids varies in temperature and rate of flow, the waste water or the like flows from an inlet 6 through a number of heat exchange sections 2 in series into a receiving section 8, through an aperture 10 in the bottom of a wall thereof, and discharges over a fixed weir 11 which thus determines the general level of the waste water throughout the heat exchanger, and cooler waste from the bottom of the heat exchange sections 2 flows along a passage 7 at the bottom to a receiving section, which in the form shown is the same as the section 8. The final discharge can be through a further section 13 having an outlet 16 and a still lower bottom level so that a drain pipe 14 entering it from the receiving section 8 and controlled by a drain cock 15 can drain the whole apparatus when desired.

Abstract: 1411562 Cathode-ray tubes PLESSEY CO Ltd 11 Jan 1973 [13 Jan 1972] 1564/72 Heading H1D A truncated cone-shaped magnetic core E for receiving toroidal beam deflection coils of a cathode-ray tube has grooved insulating rings F<SP>1</SP> and G<SP>1</SP> (F and G in Fig. 1) attached to its two ends for the receipt of the wire turns-e.g. J, Fig. 1-ring F<SP>1</SP> having twice as many grooves as ring G<SP>1</SP>, such that a single layer winding on ring F<SP>1</SP> forms a double layer winding on ring G<SP>1</SP>, and the grooves in the two rings being arranged such that in one pair of opposite quadrants, 1 and 3 in Fig. 3, those in ring G<SP>1</SP> are aligned with the odd-numbered grooves in ring F<SP>1</SP>, while in the other pair of opposite quadrants 2 and 4, they are aligned with the even-numbered grooves in ring F<SP>1</SP>. This arrangement facilitates manufacture by permitting simultaneous winding of the horizontal and vertical deflection coils, which overlap one another in each quadrant (Fig. 2, not shown), without the introduction of an undue amount of asymmetry. The groove spacing is modified adjacent the quadrant boundaries to give the required change of alignment. A detailed example of a winding scheme is provided.

Title: Improvements in ganged modular push button switch assemblies
IPC: H01H13/74
Filed: 1970-01-14
Abstract: 1291288 Push-button switches; interlocking switches GLOBE-UNION Inc 14 Jan 1970 [12 May 1969] 1887/70 Heading H1N A ganged modular push-button switch assembly comprises a plurality of switching modules 10, each module having at least one pair of fixed contacts and including a slider bar 26 carrying at least one contact member for bridging the fixed contacts, mounting bracket means 12, 14, secured to at least one extremity of each module for supporting the modules in a predetermined spatial relationship, and cam portions 30 attached to, or integral with, respective sliders 26 for co-operation with a plurality of laterally-slidable lockout segments 20 to prevent simultaneous operation of more than one slider 26. As shown in Fig. 1, the Y-shaped portion 40 takes up the play between segments 20 when a slider 26 is depressed and thereby prevents depression of any other slider until the depressed slider has been released. Known interlock means 16 may be provided. The cam configurations 30 may be formed on the front end of sliders 26 to co-operate with segments 20 accommodated in the front support bracket 12 (Fig. 6, not shown), the rear support 14 may then be omitted allowing modules 10 to be of different lengths. In the modification of Fig. 7 the cam portion may be diamond-shaped as at 62, thus preventing simultaneous depression of more than one button but not requiring release of a depressed button before another may be depressed; this is of particular use where the modules are of the push-push type. If the cam configurations are as shown at 70 in Fig. 8 the segments 20 are moved on one side only of a depressed slider and thus depression and release of buttons must be in sequential order.

Title: Improvements in gas-meters
IPC: G01F15/04
Filed: 1929-01-21
Abstract: 326,925. Kromschr÷der, F. Jan. 21, 1929. Fluid-actuated valves. -A pressure regulator and a pressure-operated shut-off valve for use in connection with gas meters are shown in Figs. 5 and 8, these having a connector piece so dimensioned and disposed that no alteration of the existing pipe lines to the meter will be necessary when the valves are substituted for the usual pipe connections. Fig. 5 shows a pressure regulator suitable for attachment to a ring r on the side wall of the meter in place of the inlet pipe connection and having a connector piece l for connection to the inlet pipe. The regulator housing contains a horizontal spindle a connected to a vertical diaphragm y and carrying two valve discs v<1>, v<2> on opposite sides of a valve seating o. The spindle Z is loaded by an adjustable spring or a weight t. An abnormally low pressure in front of the regulator will close the valve. The pressure regulator may be used with prepayment gas meters, an arm q in the prepayment mechanism w being arranged to actuate a lever r<1> engaging the valve spindle Z. A protective casing K may surround the pressure regulator and the prepayment mechanism. In modifications, the pressure regulator is soldered to the side of the meter casing. Fig. 8 shows a shut-off valve s replacing the outlet pipe connection. In the event of an abnormal drop of pressure, the valve s is closed by a spring a and it will not reopen when the gas pressure is again normal unless the valve rod C is operated or all the gas cocks have been closed to allow the gas leaking past the valve to build up a pressure on the diaphragm y.

Abstract: 950,696. Welding by fusion. UNITED AIRCRAFT CORPORATION. Jan. 19, 1962. [Feb. 1, 1961], No. 2090/62. Heading B3R [Also in Division G1] An apparatus for sensing discontinuities in a metal, e.g. joints to be welded, flaws or edges comprises a magnetic core having coplanar pole faces and a coil energized by A.C. to produce an alternating flux through the material, and a pair of windings disposed in a plane including the pole faces and responsive to distortions of the flux amplitude. The A.C. frequency is stated to be chosen to be at an optimum frequency, examples of which are given for different metals. A seam 12, Fig. 1, between two plates 16 is detected by coils 26, 28, Fig. 2, mounted on an insulating member 30 between the poles of a laminated yoke 10 in which the flux is generated by a coil 18 energized by an oscillator 20, Fig. 4, through a power amplifier 22. The coils are substantially in the plane of the pole faces. The signals picked up by the coils 26, 28 are amplified in A.C. amplifier 38, 40, and applied, via rectifying and smoothing circuits 42, 44, differentially to a meter 46 which produces a zero reading when the transducer is directly over the seam. The output may be applied to the deflection coils 50 of an electron beam welding plane to laterally move or focus the beam and/or to a welding table position control whereby the electron beam machine will follow and weld the seam. The application of the invention to the welding by a controlled electron beam machine of corrgated or honeycomb material between two panels for aircraft structures is referred to, the movable seam being detected by the apparatus and then welded. The arrangement facilitates welding in an inert atmosphere.
