Filed: 1938-08-08
Abstract: 517,828. Vehicle fittings for loading. GREENWOOD, F. Aug. 8, 1938, No. 23327. [Class 78 (iv)] A vehicle provided with an articulated or flexible movable floor is fitted with a movable frame intermediate the floor and the chassis. By locking this frame to the chassis the movable floor can be used in the normal way to load or discharge the vehicle, but by locking it to the moving floor, the floor and frame can be moved rearwardly as a unit until it overbalances and forms a loading or unloading ramp, with the frame acting as a rigid support for the floor. Fig. 1, shows a movable floor which is coiled up on the drum Y to discharge a load. When the unit is moved rearwardly, it tips about the body trunnions 17 and the movement is cushioned by shock-absorbers 18. A door carried by the posts 11 on the rear side 1 of the intermediate frame is released when latch members are raised from the keepers 13, Fig. 3. When the movable floor is functioning in the usual way, projections on its rear end swing the levers 15 to raise the latches, and when tilted to form a ramp the projections 14 striking the ground also raise the latches.

Title: Process for the production of a magnesium oxychloride suitable for chemical reactions
IPC: C01F5/30
Filed: 1936-08-25
Abstract: Magnesium oxychlorides are obtained by slowly heating an intimate mixture of pulverized magnesia and ground solid hydrates of magnesium chloride to about the temperature of fusion of the hydrate concerned. The magnesia may be wholly or partly replaced by magnesium hydroxide or by a magnesium oxychloride still capable of taking up magnesium chloride.  The reaction may be carried out in a rotary tube furnace through which the pulverulent mixture passes in countercurrent to the heating gases, a reaction temperature of 130-150 DEG  C. being suitable when MgCl26H2O is used.  When, however, lower hydrates are used with consequent increase of the reaction temperature, an externally heated closed rotary tube furnace is preferably employed. The product, which has the form of a powder, may be moistened with water or a magnesium chloride solution and pressed into shaped bodies, or shaped bodies may be formed from the magnesia and magnesium chloride and these be subjected to the heat treatment, preferably without movement of the same.  Examples are given.

Title: Improvements in and relating to electronic mapping systems
IPC: G01S7/22
Filed: 1950-09-26
Abstract: 680,594. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Sept. 26, 1950, No. 23567/50. Class 40 (vii). [Also in Group XL (b)] A system for providing an electronic map presentation, for example on the screen of a cathode-ray tube, comprises a cathode-ray tube, the screen of which is scanned in a predetermined manner, means for projecting the light emitted thereby through a map transparency having opaque markings on to a photo-electric cell, and a feedback path between the cell and the scanned cathode-ray tube, whereby variations in light intensity, as seen by the cell, due to screen irregularities are reduced. The cell output may be used to provide a presentation of the map on a cathode-ray tube which is also the plan position indicator of a radar system, the map scale and P.P.I. scale being the same and being readily variable in synchronism by a variation of the radial sweep rate. The map transparency 5 may be placed immediately in front of the screen 1a of the cathode-ray tube 1 which is scanned by a spot of normally constant intensity under the control of sweep signals applied to deflection yoke 2. The light passed by the map representation falls on photoelectric cell 6 whose output is amplified by amplifiers 7, 8 and 9. The main output of amplifier 9 may be fed to a radar P.P.I. display as mentioned above, but a portion of it is fed back to the cathode 3 of tube 1, a D.C. clamp circuit 10 being provided to maintain the cathode potential at its proper level. The feedback signal maintains a constant video signal output in the absence of map lines.

Title: Improvements relating to telephonic loud-speaker systems
IPC: H04M9/00
Filed: 1938-08-10
Abstract: 502,595. Two - may transmission. LEVY, J. Aug. 10, 1938, No. 23647. Convention date, Oct. 26, 1937. [Class 40 (iv)] In a two-way telephonic loud-speaker system, a signal in one way causes a reduction in the plate current of the amplifier in the other way and the power of the amplifier in the first way is increased by means controlled by the reduction of the plate current in the second way. In the ways 1 and 2. amplifiers each comprising two valves, T1, T<SP>1</SP>1, and T2, T<SP>1</SP>2 respectively are provided. Each amplifier is restrained and its plate current reduced by any known means such as that described in French Specification 803,389 when a signal passes along the other way. The grid bias applied to the valves T1 and T<SP>1</SP>1 is the voltage drop across a resistance R1 in the anode circuit of valves T2 and T<SP>1</SP>2. Similarly, the grid bias applied to valves T2 and T<SP>1</SP>2 is the drop across resistance R2 in the anode circuit of Tl and T<SP>1</SP>1. A signal in the path 1 reduces the anode current in the valves T2 and T<SP>1</SP>2 and the drop across R, and consequently increases the amplifying power of thevalves T1 and T<SP>1</SP>1. All the valves T1, T<SP>1</SP>1, T2, T<SP>1</SP>2 are arranged to operate on the lower bend of their characteristics when neither path is used.

Abstract: 1,100,878. Thermal storage heaters; air flow control devices. E. K. COLE Ltd. 3 June, 1966 [3 June, 1965], No. 23697/65. Headings F4U and F4V. In an electric thermal storage heater air flow through a heating passage is controlled by a damper 7 so that when the core temperature is above a given volume the damper is in a fixed position, and as the core temperature falls below the given value the damper progressively opens to allow increasing air flow through the duct. As illustrated, the damper is operated by a bimetallic strip 12 which is thermally connected to the core 3 by a metal block 13. A Y-shaped lever 14 pivoted at 15 mechanically connects the bimetallic strip 12 and the damper 7. When the core temperature is above the given level the bimetallic strip is bent to allow the damper 7 to close under gravity, and at temperatures below the given level the bimetallic strip operates on the lever 14 to open the damper. The apparatus may be constructed so that the damper is partially open in its fixed position. An auxiliary heating element 18 may be provided in series with the core heating element to heat the bimetallic strip 12 during core heating and thereby ensure rapid closing of the damper 7.
