    • 160,851. Tunstall, J. W. April 29, 1920. Cabin and deck lights.-A port light comprises a main frame fixed to the side of the vessel, a supplementary frame, and a glass holder pivoted to the supplementary frame in such a way that it may be swivelled without opening the supplementary frame. The main frame comprises a ring a with an integral flange a' which is secured by bolts. The supplementary frame comprises a ring c and a flange c . The two frames are hinged together at d, the holes in the brackets being oval so that the supplementary frame may be adjusted bodily towards its seat to equalize the pressure. A glass window holder j is pivoted on diametral pins i, and a tight joint is made between the main frame, secondary frame, and glass-holder by means of a rubber ring m, which is fixed to the secondary frame by a loose ring n. Screwed bolts q are pivoted on lugs p carried by the main frame, and forked lugs r are provided on the secondary frame for securing the two frames together by handles t. A stud u is fixed to the secondary frame and carries a catch plate v having a slot v . The movement of the plate is controlled by a stud w fixed to the secondary frame, which co-operates with a slot v . When it is required to swivel the glass-holder, the nuts tare slackened and the plate v moved to the right to free the edge of the holder, which may then be swivelled without withdrawing the secondary frame. In a modification, Fig. 3, the joint-making packing m is supported on the main frame a.

    • 408,643. Thermionic valves and valve-circuits. WOODS, W. L. J., 1, Arygll Street, London, and WARREN, S. F., 27, Lowick Road, Harrow, Middlesex. Oct. 11, 1932, Nos. 28345 and 28503. Divided on 406,292. [Classes 39 (i) and 40 (v).] In circuits for pentode valves having an indirectly heated cathode surrounded in turn by a control grid, a positive screening grid, a low-potential suppressor-grid preventing the return flow of electrons from the anode, and an anode, the suppressor grid is not connected directly to the cathode, the anode or any electrode there-between but is connected to a point in the cathode heating- current circuit. This connection is made in the valve or its base or in the external circuit. The suppressor grid may be connected directly to the centre point or one end of the heater or may be connected to a tapping on the transformer winding supplying the heater or on a potentiometer across this winding. A resistance or other filter preventing potential fluctuations in the heater from reaching the suppressor grid may be inserted in the suppressor-grid connection and may be inductive and shunted by a condenser. In a receiver with the centre point of the heater earthed through the chassis and the cathode positively biassed, the suppressor grid is connected to the chassis through a spring contact on the valve base. The suppressor grid is thus maintained at a constant voltage below that of the anode when the cathode of a variable-mu valve is variably biassed. The electrode structure described in Specification 401,305 may be modified by insulating the external screen 6 outside the anode 4 from the suppressor grid 17 and by connecting the screen 6 to the cathode 2 through the cathode support 18 and the grid 17 to the centre point of the heater 20 through a wire 19. The upper mica sheet 11 may be below the solid or grid-like metal shield 12 which may then have a smaller central aperture and be slotted to prevent contact with the grid posts. Specification 401,296 also is referred to.

    • 1,175,672. Hydraulic actuators; reciprocating pumps. E. F.J. WOODS [trading as AMOTS & CO.] Feb. 9, 1967 [Nov. 9, 1965], No.47386/65. Headings F1A and F1P. Hydraulic fluid is withdrawn from one of a pair of rams 12, 14, Fig.1 connected to a crosshead 16 for adjusting a bulk cargo discharge valve (not shown) and is supplied to the other ram by camactuated pump pistons 46 within bores 38 each having non-return valve-controlled inlet and outlet ports 34, 36, Fig.2 connected by passages 26, 32 and 28, 30 to sections 19, 21 of the slide 22 of a two-position reversing valve according to the setting thereof; the sections 19, 21 being in constant fluid connection through passages 18, 20 with rams 12, 14. The inlet and outlet ports 34, 36 of each pump bore lead to longitudinal passages connected together at one end through a pressure relieving by-pass valve (76, Fig.3, not shown). The cams 50 are carried by a shaft 48 driven by a rotary compressed air motor 72 having two independent sets of jets and inlet ports (not shown) whereby air from one set of jets rotates the motor at the same speed but in reverse direction as air from the other set of jets. The two air supplies are obtained from low and high-pressure outlet ports 91, 93, Fig.4 of a pressure responsive valve 80 supplied through a passage 88 with either low or high-pressure air from a line 78 according to the setting of a manually operated valve in a high-pressure supply line (109, Fig.7, not shown). The low and high-pressure outlet ports 90, 93 are also connected by lines 102, 104 to housings 98, 100 at opposite ends of the slide 22 to effect displacement of the latter.
