Classes 78 (3) and 78 (4) A road vehicle for carrying containers is fitted with a turntable 2 carrying a platform which has an extension member or members 6 and which can be tilted to form, with the extension member or members, a bridge for moving containers between the vehicle and the ground. In the semi-trailer illustrated the extension members 6 comprise rails formed with telescoping extensions 7 and adapted to be tilted about either of hinges 5 and 5a, when the pin of the other hinge is removed, by a pair of hydraulic rams 8 carried by a frame 3 which is mounted for slueing on the turntable 2. The container may be pulled up the rails 6, 7 by a rope 9 which passes over pulleys 12, 13 and 14 to a winch 11 operated by a handle 10. The equipment may be constructed as a fitting for detachable attachment to existing road vehicles, and may serve also to move containers between the vehicle and a raised platform in a loading bay.

Title: Improvements in or relating to radio direction finders
IPC: G01S1/02
Filed: 1936-11-20
Abstract: 485,583. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Telefunken Ges. f³r Drahtlose Telegraphie) Nov. 20, 1936, No. 31847. [Class 40 (v)] In a direction-finder, corrections both for quadrantal error and for " mast effect " are automatically added to the normal readings by composite threedimensional cams, the appropriate contour of these being selected by means geared to the wave-length switch and the tuning knob of an all-wave receiver. As shown in Figs. 2, the hand wheel Hr is geared to the directional frame (not shown), and to a rough or uncorrected scale 51. The corrected scale S is mounted concentrically with the compass card K, and an indicator ring Z, which is given a movement compounded of the rotation of the hand wheel Hr and of a correction picked up by a slider O1 riding over the composite cam MFB so as to correct for quadrantal error. The two movements are compounded in a differential gear G1. The control of the energy fed from an auxiliary aerial (not shown), in order to compensate for " mast effect," is derived from a slider O2 riding over the composite cam MHAB, through a lever 15 and gearing 17, 18 which control the mast-correction shaft HAB. The position of the sliders O1, O2 on the contour of the cams MFB, MHAB is controlled from the wavechange switch St and tuning knob D of the receiver E through the medium of a cam U, a differential gear G2, and nuts 13, 14 sliding on a screw shaft 12. The composite cams are built up of individual discs each cut for a particular wave-length, the sliders O1, O2 being shaped to give a mean value of correction between two adjacent discs.

Title: Improvements in devices for producing smoke signals and the like
Inventor: SCHERMULY ALFRED JAMES
IPC: F42B4/22
Filed: 1948-12-10
Abstract: 648,597. Pyrotechnic signalling devices. SCHERMULY PISTOL ROCKET APPARATUS; Ltd. Dec. 10, 1948, No. 31960. [Class 9 (ii)] A signalling device has a casing 1 containing a smoke-producing composition 9 and to the rear of the casing is an apertured plate 2 held in position by a cannelure 3. The aperture is stepped to form a shoulder 6 against which abuts a flange on a tube 7 containing a pressed delay composition 8. This tube may be screwed into the plate and extends into the smoke-producing composition which is ignited by the delay. A flashtube 10 is screwed into the plate and is provided with one or more holes 11 providing communication between the flash passage and an explosive charge 17 between the plate 2 and a plug 14 closing the rear of the casing 1. When the device is fired from a breech-loaded discharger, this plug has a flange 15 which rests against the rear of the barrel. If the discharger is muzzle-loaded, the plug has an annular groove coacting with a catch in the barrel. A flash-producing cap 12 is held in the flash-tube by pins 13 so that on ignition, e.g. by a firing pin, the flash passes up the tube to ignite the delay 8 and through 'the holes 11 the charge 17 which ejects the device from the discharger, the plug 14 remaining in the barrel. U.S.A. Specification 1,941,590 is referred to.

The correction voltages are generated in a circuit 7 under the control of a computer 8 and are typically a quadratic function of the cartesian coordinates of each image point. The specification describes a circuit for generating such a quadratic function using conventional analogue techniques and also a circuit using resolvers for coordinate rotation to eliminate the effect of the rotation of the image intensifier to give a stationary superimposed image on the storage tube target.

[Class 20 (iv).] A dry porous material suitable for heat insulation and like purposes is obtained by subjecting peat blocks or the like to an uninterrupted and even current of warm dry air at a temperature not exceeding 70‹ F. in a closed chamber, the blocks being kept in continuous motion by supporting them on a structure rotating about a vertical axis, in such a manner that the air current circulates freely about the blocks, substantially the whole of the surface of each block being exposed thereto. The material produced is similar to cork, is a good insulator against heat, sound, and vibration, is resilient, substantially verminproof, and has good fire-resisting qualities. The pressure in the chamber may be above atmospheric during at least a part of the process.

Title: Improvements in or relating to fluid metering and shut-off devices
Inventor: SHERLOCK JOHN EDWARD
IPC: F16K31/26
Filed: 1954-11-05
Abstract: 779,201. Valves. BRITISH THERMOSTAT CO., Ltd. Oct. 25, 1955 [Nov. 5, 1954], No. 32124/54. Class 135. A combined metering and shut-off device more particularly for controlling the supply of liquid fuel to burners comprises a metering valve 1 controlling the outlet from a float chamber 7, a floatoperated shut-off valve 9 controlling the inlet to the float chamber, and interconnecting means between the two valves whereby the shut-off valve 9 is caused to be closed by operation of a rotary manual control element 4 of the metering valve to the fully closed position. The metering valve and its actuating mechanism are as described in Specification 720,618, comprising a rotary snail cam 5 acting on a lever 6 to raise the valve against a loading spring 2. The shutoff valve 9 is urged towards closure by a weight 10 carried by a pivoted arm and opened in response to a fall of level in the float chamber by a float 12 mounted on a pivoted arm 11 which engages a pin 13 on the valve. Should the valve fail to seat effectively, the consequent rise of liquid level causes the float to engage a lever 16 to move an abutment 17 out of engagement with a lever 14 whereby the latter is brought by a spring 15 into engagement with the pin 13 to close the valve. Rotation of the element 4 to close fully the metering valve 1 brings a projection 20 into engagement with a lever 21, 22 which engages the float arm 11 to raise the float and release the lever 14 for closing the valve 9. A member 19 is operable to reset the release mechanism 14, 17. A filter 8 is fitted in the inlet to the float chamber. In a modification, the lever 6, when moved to the fully closed position of the metering valve, engages the lever 16 to trip the mechanism 14, 17.

The gauge 2 at each side carries nuts 3 engaging screws 4 operated through a crossshaft 9 by a hand wheel 17. The shaft 9 is divided and connected by a hand operated clutch to -permit each screw 4 to be independently operated for canting the back gauge. A tape 33 is connected to the nut 3 and to a spring box 42 is graduated to indicate in a window 45 the setting of the gauge.
