Abstract: 708,921. Roof lights; ventilators. GIBBONS, G. A. April 30, 1952 [March 2, 1951], No. 5061/51. Classes 20 (3) and 137. [Also in Group XXXIII] A roof light covering a circular aperture in the roof 3, Fig. 1, of a building or vehicle, comprises an annular support 6 secured to an annular web 1 surrounding the aperture, the member 6 supporting a shallow dome 13 of plastic or other transparent material and having openings 10 through which condensed water may flow to the roof. The support 6, which has the dome 13 secured to a downwardly directed flange 15 by bolts 14, has a part 11 formed with ventilating apertures 12 sloping downwardly towards an integral trough 9 wherein the openings 10 are formed. An annular drip member 5 and an inner flange 8 of support 6 are bolted at 7 to a flange 4 of the curb 1. To regulate the ventilation through apertures 12 a closure member 16 is provided having an apertured part 17 which is similar to the part 11, the member 16 being movable from open to closed position on three rollers 19 each of which is rotatably mounted on a spindle 20 carried by a frame 21 secured to the flange 22 of support 6. The rollers 19 run on inclined tracks 23 formed in the trough 9 so that in the closed position the part 17 closely overlies the part 11 whereas in the open position the parts are spaced from one another. Three further rollers are also provided each of which 24, Fig. 2, rotates on a spindle 25 carried in a frame 26 secured to flange 22 of support 16, a plate 26a pivotally mounted on the flange 8 being spring urged to press the closure member 16 downwardly. The closure member is moved between open and closed positions by links and a lever fixed to a pulley, the latter being operated from a distance by means of Bowden cables. The curb 1, drip member 5, support 6 and closure member 16 may be formed of sheet metal, plastics or asbestos cement and may be reinforced at their edges by wires 33 embedded therein. An asphalt or mastic weatherproofing coating 3a is provided on the curb 1 and roof 3. In a modification the curb is formed as part of the roof, the members 5, 6 being bolted directly thereto. According to the Provisional Specification glazing bars may be used to obtain particular aesthetic effects.

A fastening, e.g. for a hinged door 109, which prevents movement of the door in one direction relative to a door frame 124, comprises a housing 111 secured to the door, a fastening member 121 and an actuating member 113 respectively pivotally mounted in the housing on pins 122, 114, and a link connecting members 121 and 113 through pivot pins 127, 126 respectively. In the fastened position shown, the slightly non co-linear relationship of pins 127, 126 and 114 ensures that fastening tongue 123 will not move in the direction Q to the unfastened position, Fig. 2 (not shown), unless the actuating member 113 is manually operated. To unfasten the door, a plate 117, secured to the actuating member, is rotated about pin 114 in the direction P, thus rotating the fastening member about pin 122 in the direction Q. A spring 130 snaps the linkage into its two extreme positions. The tongue 123 and/or the link 125 may be resilient. In a modification. Figs. 5-8 (not shown), the length of the link is adjustable.

Fire between aircraft propeller blades, controlling and synchronizing.-Relates to machine guns of the recoiling-barrel type mounted on aeroplanes and controlled by the propelling-motor to fire between the blades of the propeller. According to the invention, the fire control is performed by a single rod, which can oscillate about its axis, and is provided at each end with a lever, one lever being worked by the motor, and the other lever working the gun. In the form shown, the rod f. Fig. 1, is mounted at one end in a ball-and-socket joint d on the frame carrying the motor shaft a, and at the other end in a spherical bearing c', which allows the rod f freedom of oscillation as well as longitudinal play, so as not to be influenced by vibrations and distortions of the motor and the fuselage. The lever g at one end of the rod f is worked by the cam b on the shaft a through the medium of a bolt c; the lever g is normally kept out of action, in the position indicated by dotted lines in Fig. 2, by a spring g<1>, and is put in action by a pull on a Bowden wire g<0>. The lever h at the other end of the rod f works the gun through the medium of a bolt i, j, Fig. 3, which is kept against the lever h by a spring k. This bolt and the bearing e<1> are both carried on the gun by a bracket e.

A mechanism converting rotary motion of a worm-wheel 9, driven by a worm 11, into linear motion of a driven piston (1, Fig. 1, not shown) comprises a disc 2, rotatable in the big end of a connecting-rod 20, the little end of which resiliently engages the piston 1, and also eccentrically rotatable on an eccentric portion 3 of a shaft 4 rotatable about a fixed axis 15, the disc 2 and shaft 4 having crank-pins 6, 7, respectively, which engage in a cam groove 8 in the face of the worm-wheel 9, the cam groove being so shaped that on rotation of the wheel 9, first one eccentric is rotated alone, and then the other is rotated alone. The mechanism provides rapid initial movement and slower final closing of a valve closure member operationally connected to the piston (1). A gudgeon pin member (21) is resiliently urged towards the end of the connecting-rod (20) by Belleville washers (23) to provide a resilient seating load on the valve closure member in the closed position thereof. Starting with the valve fully open, the crank-pins 6, 7 are at positions A 0 , B 0 , respectively (Fig. 3). During a half-revolution of the wheel 9 the pin 7 is engaged in a semi-circular portion 25 of the groove 8, so that the shaft 4 does not rotate, while the pin 6 is moved by a portion 26 of the groove to a position A 2 , the disc 2 being rotated through 180 degrees to displace the piston (1). During a second halfrevolution of the wheel 9, the pin 6 is engaged in the portion 25 so that the disc 2 does not rotate, while the pin 7 is moved by a portion 27 of the groove to a position B 2 , the shaft 4 being rotated through 180 degrees to displace the piston (1) a further, smaller amount to seat the valve closure member.

Abstract: 1,199,841. Coulometric titration. W.A. WISEMAN. Jan.22, 1969 [Feb.2, 1968], No.5526/68. Heading G1N. In a method and apparatus for determining the concentration of a combustible material in a gas stream, 5, a gas (e.g. oxygen) reactive with the material is produced in an electrolytic generator, 1, the resulting mixture being allowed to react intermittently in a reactor, 2, and the residual oxygen content being measured in a detector, 3, which controls through an amplifier, 4, the intermittent activation of the generator so as to maintain the oxygen level constant. The intermittent control of the reactor is effected by a circuit 8 which includes an integrator to measure the amounts of charge passed by the generator during reactive and non-reactive periods respectively. The difference between these charges is empirically related to the required concentration which is displayed at 9. Figs 1a, 1b (not shown) are detail modifications to the embodiment of Fig. 1. Figs.2 and 3 (not shown) illustrate alternative embodiments for use with oxygen-bearing gas streams, in which the reactor 2 is up-stream of the generator 1, the latter embodiment also including a second generator (7) to ensure a complete reaction. In Fig.4, a generator 10 and reactor 11 act to provide a "clean" gas stream at 12 i.e. substantially zero combustible material content, an exchange system 13 introducing combustible material e.g. hydrocarbons from water, which is measured as before. Alternatively exchange system 13 may include a second gas stream so that reactions may be effected before mixing with the gas stream 5. In another embodiment the exchange system may include water or other liquid to remove oxygen and generators 1 and 10 may produce hydrogen when 3 will be a hydrogen detector. The generator, reactor, detector and amplifier are as described in Specification 1, 112, 771 to which reference is made.
