A tapered cock plug 9 held in a tapered portion of the tube 11 by a spring 14 bearing on a circlip 15 is drivably connected to the bracket 8 by means of a spindle 16 engaging in a journal 19 secured to the bracket. A tubular trunnion 24 in threaded engagement with the interior of the other end of the tube 11 receives a pipe 25 leading to the burners 26. The plug 9 has an axial bore 28 which registers with the trunnion 24 and a side port 29 which, when the hot-plate 3 is horizontal, registers with the bore 12 through which gas supplied to the tube 10 passes. When the hot-plate 3 is lifted, the plug 9 and trunnion 24 rotate and the gas supply is cut off. In an alternative embodiment (not shown), the bracket is secured to the housing and the body to the hot-plate 3, the bore 12 connecting with the burners and the pipe 25 with the gas supply, and the tube 11 rotating on the plug 9 to disconnect the bore 12 and port 20. According to the Provisional Specification, isolating means for an electrically heated apparatus comprises a lever-operated switch, the lever of which moves about an axis parallel to the hinge axis or coaxial therewith. An arm rigidly connected to the movable part of the apparatus is curved with a radius equal to the effective length of the lever to which it is connected by the engagement of a pin on the lever with a slot in the arm. The slot, through lost motion, permits snap action of the switch to the on or off position to which it is urged by the engagement of the pin with one end of the slot. Alternatively, the arm may be pivotally secured to the movable part either at a point eccentric to the hinge axis, or coaxially with the hinge, in which case studs may be formed on the movable part to engage the arm and urge it towards the on and off positions. A rotary switch may be similarly mounted and connected by axial coupling, allowing lost motion if required.

Abstract: 723,960. Directive radio systems. STAN. DARD TELEPHONES & CABLES, Ltd. May 17, 1946 [May 21, 1945], No. 15010/46. Class 40 (7). In a directional aerial system comprising two spaced primary aerials in which the mutual reaction of the primary aerials tends to distort their respective radiation patterns from symmetry, auxiliary parasitic aerials are mounted on opposite sides of the two primary aerials in such a manner that re-radiation from. the auxiliary aerials will substantially compensate the distortion. The invention is described as applied to a direction-finder of the type disclosed in Specification 685,990 in which two spaced aerials 1 and 2 backed by a reflecting screen 13 and having symmetrical radiation patterns 14 and 15 are coupled in opposition by transmission lines 5 and 6, the output to the receiver and indicator 4 being taken from a tapping-point on the lines 5 and 6 which is oscillated by means of a motor 12 so that the null of the resultant radiation pattern is oscillated in azimuth. Due to the mutual reaction of the aerials 1 and 2, the radiation patterns 14 and 15 are distorted into the unsymmetrical shapes 19 and 20 causing erroneous direction indications and according to the present invention the distortion is compensated by the parasitic aerials 23 and 26 located on either side of and in line with aerials 1 and 2, the spacing between aerials 1 and 23 and between aerials 2 and 26 being equal to the spacing between aerials 1 and 2. The two radiation patterns due to aerials 1, 23 and 2, 26, respectively, are now symmetrical, as shown at 25 and 28. The two parasitic aerials are earthed through impedances 24 and 27 substantially equal to the impedance presented to aerials 1 and 2 in the phasing circuit 3 and in order to effect impedance matching over a wide frequency band, all the aerial elements may comprise double conical surfaces, Fig. 2 (not shown). When the distortion due to the mutual reaction of serials 1 and 2 is excessive, additional parasitic aerials may be employed.

Abstract: 1425897 Latching mechanisms WEST ALLOY DIECASTINGS Ltd 28 March 1974 [29 March 1973] 15236/73 Heading E2A  A door latching mechanism in which radial downward and upward swinging movement imparted to a door lever handle 8 to retracts or projects the spring-loaded latch 2, movement of the latch by the handle is effected through the intermediary of a ball or roller 5 allowed to fall by gravity from a cavity 1A in the latch casing into a cavity 7A in one face of an actuating cam 7 movable by the handle so as to co-act with the latch to retract the latter against the influence of a spring or springs 3. The arrangement is such that the ball can be made to occupy an inoperative position in the casing in which it permits the latch to be urged by the spring 3 into a projected latching position, or alternatively, a position in which it transmits movement to the latch to retract the latter into the latch casing 1, the ball and its associated mechanism being duplicated as an identical mirror image both at the top and bottom of the latch casing so that according to which side of the latch is disposed uppermost (to suit right or left hand hanging of the door) one of the balls and its associated mechanism is rendered operable and the other inoperable. As shown, the ball 5 is disposed in the recess 7A in the cam 7 and a recess 2A in the side 2C of the latch 2, movement of the lever 8 downwardly causing the ball to transmit movement from the cam via the ball to the latch to retract the latch; release of the handle allows the spring 3 to project the latch. Upward movement of the handle turns the cam to allow the ball to move freely in the recess 2A and to bring the cam face 7C into contact with the face 2E of the latch whereby the latter is restrained from retraction; release of the latch is effected by moving the handle to the neutral position. Resistance to movement of the cam 7 and handle to the neutral and snib positions is provided for by a spring-loaded ball 9 engageable in recesses 1C, 1D and 1E. For operating the latch from the exterior of the door the cam and lever can be turned by inserting and rotating a blade, e.g. forming an integral part of a key-operated barrel lock, through a hole in a cam 12 and a hole 8A in the handle; the cam 12 and balls 10, 11 constitute the means for operating the latch from the exterior of the door.
