Title: Apparatus for washing motor vehicles
IPC: B60S3/06
Filed: 1968-08-23
Abstract: 1,222,839. Vehicle-washing apparatus. O. CHRIST, [trading as OTTO CHRIST MACHINENFABRIK]. 23 Aug., 1968 [3 April, 1968], No. 40400/68. Heading B7J. A vehicle-washing apparatus includes a gantry frame 11; rotatable washing brushes 1, 2, each with a normally vertical axis but capable of arcuate displacement, by contact with a vehicle to be washed, about a horizontal axis 4 which is at right-angles to the direction of movement of the vehicle, and biased towards the vehicle by means of a helical spring 14 co-operating with a rope arrangement 15; sensing means 8 for detecting arcuate movement of each brush of a predetermined magnitude; and shifting devices 10 for shifting the washing brushes, in a direction opposite to those in which the brushes are biased, when the sensing means are actuated. Each brush 1 and 2 is suspended from a trolley 21 movably supported on a rail guide 3 which is in turn supported in bearings 5, 6 which allow arcuate movement of the rail and brush. Each brush is rotatable by a motor 12 mounted on the trolley 21. The sensing means 8 comprise switches operable, according to the direction of movement of the frame relative to the vehicle, by a stud 27 on the end of the rail 3. The gantry frame has rollers 18 movable along rails by drives 19 and carries a horizontal rotatable brush 20, vertically movable in guides in the frame side members 16. In another embodiment, Figs. 2 and 3 (not shown), each guide 3 is fixed rigidly to the gantry frame and supports a bearing upon which the respective brush is pivotable. The shifting device consists of a double-acting pneumatic cylinder 23 and piston 22 arranged so that the cylinder entrains the brush only when the cylinder is moving away from the vehicle towards the side of the frame 11.
Patent GB-942103-A (GB)
Title: Inorganic polymeric materials
IPC: D01F9/00
Filed: 1961-11-14
Abstract: Solid inorganic polymer products are obtained by dissolving a water-soluble metal salt of an aliphatic carboxylic acid in water, purifying the solution, subjecting the solution to a combination of temperatures and pressures until the concentrate contains the equivalent of at least 50% by weight of the oxide of the metal whose salt was initially dissolved, polymerizing the concentrate by suitable heat treatment and then forming solid shapes from the polymer and finally firing the shapes to eliminate any organic material therein and to yield microcrystalline metal oxide products of high strength and flexibility.  The metal whose salt is initially dissolved is selected from metals whose hydrous oxides are precipitated at pH values less than 7 on treatment of a metal salt with an alkali, and whose hydrous oxides after washing and dispersion in distilled water give a pH of less than 7, i.e. aluminium, yttrium, the lanthanides, titanium, zirconium, hafnium, thorium and the metals having atomic numbers 23 to 28 inclusive may be used.  Combinations of metals may be used, one metal being one of the above specified ones, provided that the combination of hydrous oxides can be precipitated at pH values of less than 7 &c. Carboxylic acids which may be used are mono- and poly-carboxylic acids and substituted acids, e.g. ethoxyacetic and chloroacetic acid, the preferred acids being acetic, formic and adipic acids. Metal salts of a single acid or a mixture of such acids may be used, provided the compounds are completely water-soluble or are rendered soluble if sufficient acid is present. The carboxylic acid solution is purified, e.g. by filtration, the solution is concentrated preferably by vacuum concentration between 15 DEG  and 25 DEG  C. and then it is polymerized preferably by heat treatment in a closed vessel between 60 DEG  and 90 DEG  C.  Alternatively, the solution may be simultaneously concentrated and polymerized by heat treatment between 60 DEG  and 90 DEG  C. under atmospheric pressure. Alternatively, a freshly precipitated hydrous oxide derivative may be added to an anhydrous solution of a carboxylic acid, thus precipitating a metal carboxylate salt which is redigested in additional anhydrous carboxylic acid at elevated temperatures, the resulting product being a polymeric liquid.  Continuous monofilaments, sheets, slabs or other shapes, e.g. short fibres, may be formed from the polymer and then fired to produce microcrystalline metal oxide products free from any organic material.

A magnetic separation device comprises two sloping channel members 2 of non-magnetic material, a magnet 23 mounted under each channel and arranged to be moved away from the channel by an air cylinder 28. A cover 3 for the channels is provided with an arcuate opening 7 over which is mounted an inlet pipe 30. The channels discharge through outlets 5 into a dish 1H which is divided into two compartments and which is rotatably mounted about a shaft 18. Each channel is provided with a manifold 9 having a number of jets 10 through which a wash liquid is fed to the channel. The inlet pipe 30 and dish 14 are coupled by linkage so that the compartments in the dish are moved under the outlets as the pipe 30 is moved from one channel to the other. The arrangement is such that material containing iron is fed into a trough and is deposited in one of the compartments of the dish, the iron being retained in the channel by the magnet. The pipe 30 is moved to the other channel at the same time rotating the dish so that the material is fed to the same compartment. The compartment with the iron is then subjected to a wash liquid which deposits the iron in the other compartment of the dish.

The tunnel diode 7 is preferably biased by a voltage having a constant component developed across a Zener diode 10 and a variable component depending on the difference in voltage at points 2 and 3. When transistor 20 is turned on, tunnel diode 7 is switched to its low voltage state, turning off transistor 1 and effectively coupling the variable voltage at point 3 to the load 30. Turning off transistor 20 switches tunnel diode 7 to its high voltage state, turning on transistor 1 and coupling the load to the variable voltage at point 2.

Abstract: 1,173,937. Photo-electric concentration measurement of suspensions. ROBERT BOSCH G.m.b.H. Sept. 22, 1967 [Sept. 24, 1966], No.43208/67. Heading G1A. The concentration of a gaseous suspension is measured by comparing the intensity of light dispersed by the suspension with light transmitted through the suspension, a photo-electric detector being moveable from one position to another to receive the two kinds of light. In Fig. 3 the gaseous suspension flows through a pipe 2 having bores 9a, 9b and 9c. A photo-electric device 14, mounted upon a rotatable sleeve 11 containing apertures 13a, 13b, receives in the position shown dispersed light through bores 9c. When rotated through 90 degrees the photo-electric device receives the transmitted colluminated light beam 7 through bores 9a 9b. The pointer of an indicator can be set to full deflection for the transmitted light and to zero when the photo-electric device receives no light as when the sleeve is turned so that the pipe closes the tube 12 continaing the device. A nozzle injects the suspension into the pipe 2 and at the same time draws in fresh air to envelop the suspension to clean and cool the pipe 2.
