Apparatus for washing a vertical surface of a vehicle includes an horizontal, rotatable brush supported in mountings which are movable vertically downwards to carry the brush over the surface to be washed. In the illustrated apparatus such a brush 13 is used to wash the top and rear surfaces of a vehicle. The vehicle moves from right to left as indicated in Fig. 3 passing between the vertical, rotary brushes 12 which wash the sides and, beneath the horizontal, rotary brush 13 for washing the top. After passing through the brush system the vehicle is halted at a predetermined location for its back washing by brush 13 which is rotated forwards through 90 degrees about the axis of a shaft 43 by a fluid pressure motor 48 Fig. 2, and is carried vertically downwards by belts 54. Cleaning liquid for the top and sides is supplied through spray nozzles in pipes 26, 27, Fig. 2, of inverted U-shape and for the back through spray nozzles in transverse, horizontal pipes 71, 72, which move vertically with brush 13. Transverse beams of light incident on photosensitive cells are interrupted by movement of the vehicle through the brush system and are used to control the correct height of brush 13 for top washing and the correct position of the vehicle for back washing. An electrical circuit controls the whole operational cycle including the correct positioning of brushes and the supply of cleaning liquid, except that manual switching is required to initiate back washing.

Abstract: 919,419. Cathode materials and processing. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 20, 1960 [Jan. 23, 1959], No. 2082/60. Class 39 (1). In a method of making an impregnated cathode, at least part of the surface of a porous refractory body 10 is carbonized or provided with a layer of carbon and the body is impregnated through the resulting carbide or carbon layer 15 with pre-molten barium aluminate. The body 10 is afterwards incorporated into a cathode structure 17, at least part of its surface being free of carbon and carbide to constitute a high-emission area 12. Non-porous parts of the cathode structure, e.g. molybdenum cylinder 17, may also be carbonized to reduce emission therefrom. Carbonization of porous body 10, which may be of tungsten, or a tungsten-molybdenum alloy, or a tantalum-molybdenum alloy, may be effected by embedding it in carbon or graphite powder and heating to a temperature of 1200‹ to 1700‹ C. for 5 to 15 minutes to form a carbide layer 10 to 40 microns thick, the area 12 being protected against carbonization by a templet or having its carbide coating removed afterwards by mechanical treatment or by heating alternately in a reducing and in an oxidizing atmosphere. Alternatively, a layer of carbide may be sprayed or painted on to the surface of body 10 and caused to adhere thereto by sintering, or the porous body may be heated in naphthalene vapour. As a further alternative a layer of carbon or graphite powder or a compound such as sugar, which decomposes to carbon on heating, may be used, the layer of carbon being brushed off after impregnation, a protective layer of tungsten, which may have been provided on the high emission areas, also being removed. A composite porous body can also be formed by welding together carbonized and non-carbonized parts. A specific example is given.

Title: Improvements in or relating to the purification of water
IPC: C02F1/52
Filed: 1955-01-25
Abstract: To remove fluorides dissolved therein, water is subjected to treatment at a temperature of 50 DEG C. or more with tri-calcium orthophosphate, and calcium carbonate and/or magnesium carbonate. The reagents may be added to the water either singly or together. When the water to be treated is alkaline, or becomes so on boiling, ammonium chloride may be added to the reacting substances.  The treated water may be passed subsequently to a conventional water filter.  In one example fluoride-containing water was boiled for a quarter-of-an-hour with commercial-grade tri-calcium orthophosphate and powdered marble chips.  In another example the same procedure was followed, with the addition of commercial-grade ammonium chloride to the reactants.  For the tri-calcium orthophosphate there may be substituted any material or materials which can produce it under the conditions of the process.  The process may be used in addition to any conventional water-purification process.

Abstract: 542,277. Valve circuits. DALGLEISH, J. W., POOLE, S. R., and PYE, Ltd. Feb. 7, 1940, No. 2374. [Class 40 (v)] In a transmitter comprising a master oscillator and grid-modulated power amplifier, the grid bias voltage for the power amplifier is derived by rectification of the H.F. voltage generated by the oscillator, whereby the H.F. drive voltage and the bias voltage applied to the power amplifier bear a fixed relationship to each other. High frequency voltage from the anode 4 of the master oscillator is fed to the grid 3 of the power amplifier. High frequency current is fed through condenser 5 and resistance 10 to a diode anode 6 which co-operates with the cathode of the oscillator. The rectified voltage developed across resistance 7 is fed via filter 8, 9 as a bias to grid 3, the microphone M being coupled in this lead by transformer 11. A variable condenser 12 enables the relationship of the H.F. voltage and grid bias to be adjusted. A suitable grid bias battery is connected between resistor 7 and earth which acts as a delay voltage for the diode 6 and ensures that the power amplifier will not be operated without bias in the event of failure of the H.F. voltage.

Abstract: 550,714. Patterned screens formed of polarizing elements. KODAK, Ltd. (Eastman Kodak Co.). July 17, 1941, No. 2442/42. Divided out of 544,034. Drawings to Specification. [Classes 97 (i) and 98 (ii)] A screen for making a patterned, e.g. a halftone, photographic reproduction is formed of a number of similar juxtaposed elements, all of which are identical and in each of which the light polarization properties vary at different points. The screens may be formed by an inbibition process, a relief image being used to apply de-polarizing solution to the polarizing material so that an image is formed on the latter in terms of varying degrees of polarization. The relief image may be formed by exposing a wash-off relief emulsion to light passed through a ruled half-tone screen placed at half-tone distance from it. Alternatively, the polarizing screen may be formed from a layer of plane polarizing material comprising a water-swellable binder and a light-sensitive substance, the image being formed, after exposure, by a wash-off process. The screen may be employed for controlling the contrast in half-tone reproduction as described in Specification 544,034; or the light from the record being copied may be passed through a filter which polarizes it in a plane transverse to the plane of polarization of the half-tone screen, and the apparent contrast of the latter varied by a quarter-wave plate between the filter and screen. Specifications 528,796 and 547,554 also are referred to.

Abstract: 399,190. Fluid-pressure brakes. AVERY, W. L., Blue House, Thorley, Bishop's Stortford, Hertfordshire. Jan. 27, 1932, No. 2470. [Class 103 (i).] Hydraulic brake mechanism particularly for aircraft and other vehicles which permits of the simultaneous application of the wheel brakes on the two sides of the vehicle by a handlever or the like and the differential operation of the brakes for steering by the rudder bar or other steering member comprises a T-shaped lever d adapted to engage the pistonrods c<1>, c<2> of the two brake systems and pivotally carried at d<1> by one arm e of a bellcrank the other arm e<1> of which is engaged by a roller g<1> on an arm g secured to the hand-lever f pivoted at f<1>. A pin e<2> on a link i connected to the rudder bar engages a slot in the member d so that after this member has been brought into contact with the piston-rods one or other of these may be depressed by movement of the rudder bar to apply one or other of the brakes. By further movement of the lever f both brakes may be applied or further applied whether or not the brakes are under the influence of the rudder bar. The arrangement is such that the leverage increases as the effort applied by the lever f increases. A reservoir n for making up fluid leakage losses in the brake system is connected through passages n<3>, n<4> and a plugcock o to the cylinders a<1>, a<2> which are connected respectively to the two brakes by pipes a<3>, a<4>. The cock o is closed by a spring when the brakes are applied and is opened by a projection on the lever f when that lever is in normal position. To limit the braking pressure that can be applied, passages p<1>, p<2> leading from the cylinders a<1>, a<2> to the reservoir are closed by ball-valves q<1>, q<2> acted upon by a common spring r through a member r<1>. The reservoir n has a piston n<1> which may be acted upon by a light spring n<2> and a stiffer spring s may also be provided to prevent the reservoir from being completely filled and thus allow space for the return of liquid expelled from the system through the ball-valves q<1>, q<2> when braking.
