[Class 125(iii)] A screw cap stopper 1 for a tube, bottle or the like has two arms 2 having lugs 7 which slidably and pivotally secure the cap to a ring 9 by engaging in grooves 8, the ring 9 being rotatably mounted on the neck of the tube or bottle below a threaded part 4. The ring is held against axial movement by a flange 10 which snaps into a groove 11 at the base of the neck. The grooves 8 impart springiness to the ring 9 whereby it may be passed over the screw threads 4 to embrace the plain part of the neck. The lugs 7 are of rectangular section, the vertical dimension of the lugs being greater than the width of the slots 8 so that, as the cap is swung away from the mouth of the container the lugs 7 bind in the slots and retain the cap in a non-obstructing position. The resilience of the arms 2 permits the lugs 7 to be sprung into the slots 8. In a modification, the flange 10 is dispensed with, a pin being arranged to project inwardly from the ring 9 to engage a circular groove in the neck of the container, just below the screw threads 4. According to the Specification as open to inspection under Sect. 91, the lugs 7 are pivoted in a sleeve which is rotatable and slidable on the neck of the container. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in oscillograph electric transient analysers
IPC: G01R13/32
Filed: 1936-10-07
Abstract: 482,994. Oscillographs. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 7, 1936, No. 24927/37. Divided out of 482,956. [Class 37] [Also in Group XL] A cathode-ray oscillograph for analyzing transients includes a time-sweep circuit and impulse generator, the impulse generator including a surge condenser and grid-controlled discharge tube the grid-cathode circuit of which includes a pair of series rectifiers, and to the junction of the rectifiers a synchronizing condenser connects with the time-sweep circuit, the arrangement permitting current to flow through one rectifier when the sweep condenser discharges while when it charges, a flow through the other rectifier passes to the control grid and initiates a surge. A peaking circuit 1, timesweep circuit 2 and impulse generator 3 discharging into circuit 18 or connected to the test circuit are shown. A circuit 12 for extinguishing the spot when tube 10 ignites is also provided. The surge generator is fed through transformer 13 and rectifier 14. The gridcathode circuit of the grid-controlled tube 17 contains rectifiers 21, 22 in series and optionally a rheostat 23 across resistor 20 through which a normal negative bias is obtained from battery 19. The anode circuit of rectifier 14 is connected to the cathode of tube 17 and contains a resistor 15 and surge condenser 16. The junction of rectifiers 21, 22 contains a synchronizing condenser 24 connected to the time-sweep circuit. While the surge condenser 16 is charging a negative potential is applied to the grid of tube 17 preventing release of the surge, and this potential is sufficient to prevent tripping of the tube 17 by the time-sweep circuit which can thus be operated at twice the frequency of supply to the impulse generator circuit, a zero line trace between the surges being produced on the screen. In modifications, Fig. 3, the peaking circuit is controlled by a valve or other high-frequency oscillator 25 the output of which is fed to the surge generator through additional transformer windings S2, S3. In this arrangement, both 14a and 17 are gridcontrolled discharge tubes, and the resistor 15 may be dispensed with. Two surge generators 3, 3<1> may be employed, one discharging a surge whilst the other is charging, no zero line being then traced upon the screen. The duplicate generator is connected in opposite polarity to further transformer windings S4, S5. Specifications 482,956 ; and 482,957, [Group XXXV], are referred to.

Abstract: 629,991. Oil-break switches. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Sept. 12, 1947, No. 25076. Convention date, Sept. 12 , 1946. [Class 38(v)] A liquid-break circuit - breaker comprises a relatively-fixed contact 15 co - operating with an intermediate contact 16 to produce a pressure-generating arc 18, and a movable contact 17 co-operating with contact 16 to produce an interrupting arc 20, the arcs being struck in chambers 19 and 21 formed by a plate structure 5 similar to that of Specification 571,091, and has valve means responsive to the pressure in the pressure - generating chamber 19 for controlling the flow of fluid into and/ or from the interrupting chamber 21. The contact 17 is followed by contact 16 upon downward movement of the former to draw the arc 18, the interrupting arc being drawn when a flange 50 on contact 16 strikes the shoulder 51 on plate 52. In Fig. 2, the exhaust passages 26 from the chamber 21 are controlled by valves 14, urged into the position shown by springs 43 which also hold a plate 36 carrying the contact 15. With high-current arcs, the pressure in the chamber 19 lifts plate 36, the effective surface of which is increased as cylinders 46 leave recesses 47, and opens valves 14 so that a blast of fluid flows through passages 22, 23 on to the arc 20 and exhausts through passages 26. With low-current arcs, however, the pressure is insufficient to open valves 14 and the blast is effected when the contact leaves its aperture in the plate structure 5, as shown in Fig. 2. A normally-open annular valve 39, in a recess 42 whose volume is equal to that of the contact 16 closes upon closure of contacts 15, 16 so as to prevent blocking of the upward movement of contact 16 due to the incompressible oil. In a modification (Fig. 5, not shown), the contact 17 is prevented from leaving the aperture in the plates, the contact 17 having at its lower end, a contact co-operating with a disconnect contact on the operating cross bar (Fig. 1, not shown). Instead of controlling the exhaust passages 26 by valves 14, the inlet passages 22 may be controlled by spring-urged valves 62, Fig. 7, whose operation is likewise dependent upon the pressure in chamber 19. The valve arrangements of Figs. 2 and 7 may be incorporated into one unit (Figs. 9 and 10, not shown).
