Title: Methods of Washing Vehicles
Inventor: EICHWALD ERIC
IPC: C11D7/06
Filed: 1968-12-23
Abstract: 1,192,860. Vehicle cleansing apparatus. ARROW LABORATORIES Inc. 23 Dec., 1968, No. 61203/68. Heading B7J. [Also in Division C5] A method of washing a vehicle comprises applying to the outer surface of the vehicle first, an acid aqueous solution which also contains a surfactant which is soluble and stable in acid solution, and second, an alkaline aqueous solution to neutralize or remove the acid. In a preferred method the acid aqueous solution contains hydrofluoric acid at a concentration of from 0À01% to 0À2% by weight and/or fluoboric acid. The surfactant in the acid aqueous solution may be non-ionic and have a concentration of from 0À01% to 0À2% by weight of the acid aqueous solution. Alternatively or additionally the acid aqueous solution may contain a cationic surfactant, which when absorbed does not make the surface hydrophobic, at a concentration of from 0À005% to 0À1% of the weight of acid aqueous solution. This cationic surfactant has the general formula where A which may be the same or different in each case is a polyether chain made up of -CH 2 -CH 2 -O- and/or -CH(CH 3 )-CH 2 - O- units and B is an alkene diradical such as an ethylene diradical. The alkaline aqueous solution contains sequestering agents such as sodium metasilicate, potassium tetrapyrophosphate, ammonia triacetic acid and ethylenediamine tetra-acetic acid and also an alkali-stable surfactant. At least a quarter by weight of the alkaline material used in the alkaline solution is in the form of potassium compounds and the solution is at a dilution of from 50: 1 to 600: 1 by weight of the alkaline solids used. Soft water is preferably employed in the preparation of the solutions and the vehicle is given a final rinse in water. The volume of each solution used is not less than 1 gallon per 50 sq. feet of vehicle surface. Specific formulations of the solution compositions are described (see Divisions C4-C5). The solutions may be applied by spraying from a vertically displaceable horizontal rectangular frame arranged round the vehicle.

Title: A self-tuning vibration absorber
IPC: F16F7/10
Filed: 1968-12-24
Abstract: 1,248,460. Vibration dampers. BOEING CO. 24 Dec., 1968 [29 Dec., 1967], No. 61419/68. Heading F2S. In a vibration damper of the kind in which a mass 15 is supported by springs 16, 17 from a body 11 which, in use, is attached to vibrating apparatus 10, the resonant frequency of the mass-spring system is made to vary automatically to maintain it equal to that of the vibrations applied to the body 11. This is achieved by the use of supplementary masses 19, 20, 21, 22 which are pivotally connected to the body 11 and to the main mass 15: variation in the position of these supplementary masses changes the effective value of the total inertia mass, and the apparatus includes an actuator 30 which varies the positions of the supplementary masses in accordance with the differences between the instantaneous values of the frequency of vibration of the mass 15 and the body 11. The automatic control means includes transducers 60, 61, Fig. 5 sensing the acceleration of the housing 11 and mass 15. The outputs of these transducers are compared in a phase detector 62 which produces an output dependent on the difference between the frequency of vibration of the housing and the mass. This output, amplified by the units 63-65, operates the actuator 30 to restore equality of the two frequencies.

Patent GB-616029-A (GB)
IPC: B64C27/51
Abstract: 616,029. Rotary winged aircraft. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. Aug. 21, 1946, No. 24895. [Class 4] In an aircraft sustaining rotor carrying flapping rotor blades mounted for pitch changes the blade pitch angles and flapping angles are interdependent ; a flapping oscillation of once per revolution is accompanied by a pitchangle oscillation of the same frequency and of equal or greater and proportional amplitude and so displaced in phase from the flapping oscillation that the azimuth of minimum pitch angle is displaced from that of maximum upward flapping by an angle α satisfying approximately the relation : tan α+<SP>1</SP>/d 1  sec. #=2J/K, where d 1  is the ratio of pitch angle amplitude to flapping angle amplitude, J is the moment of inertia of the blade about its flapping pivot and K is the integral over the blade span of ¢par<SP>3</SP> cdr, where p is the air density, a the rate of increase of lift coefficient with angle of incidence and c the chord of a blade element at radius r from the axis of rotation. Two constructions by which this result may be obtained are described. In one, Fig. 2, the blades are linked so that the pitch angle of each blade is determined by the flapping angle of the blade leading it. Each blade 23, 24 is mounted on the hub 33 by a pitch-change pivot (not shown), a flapping pivot 27, 28 and a drag pivot 32. Each blade is connected to the next by a pair of links 20, 21 connected together by a ball joint 22. Link 20 is connected to the leading blade stub 23a on a pivot 25 whose axis intersects that of the flapping pivot 27 at rightangles and normally is parallel to the axis of the drag pivot 32. Link 21 is connected to' the following blade 24 outboard of the flapping pivot 28, by a pivot 28 whose axis is parallel to the axis of rotation when the blade 24 has its basic pitch angle. The joint 22 lies normally in the plane of the axes 29, 30 of the blades. Thus flapping motion of the blade 23 causes pitch change of the blade 24. If p=g/f and q=e/f where e, f, g are the dimensions of the linkage shown in the drawing, where α and d 1  have the same significance as above and N is the number of blades. Thus by suitable choice of the dimensions of the linkage the specified relation can be satisfied. In the second construction each blade is connected by a link lying in the plane containing the axis of the blade and the axis of rotation to a gimbal-mounted swash plate rotating with the hub, and a second link connects a pitch change lever, extending from the blade in a direction contrary to the direction of rotation and so attached as to be unaffected by flapping, to a point on the swash plate displaced in azimuth in the opposite direction to that of rotation by the angle α.

Title: Method and apparatus for vacuum deposition of semiconductor layers
IPC: C30B23/02
Filed: 1979-05-11
Abstract: A method of vacuum deposition of semiconductor layers on a substrate consists in that a starting material is charged into evaporators (3) heated to a temperature below the boiling point of the starting material. The material is fed periodically by charging in succession each of the evaporators (3), charged amount of material being selected so as to provide uniform coating of the working surface of the evaporator (3) and to give complete evaporation of this amount during the period (T) up to the next charging operation. The number of evaporators (3) is a multiple of the number of main fractions in the starting material. Charging is suitably carried out at in the interval equal to T DIVIDED n for a period 10 - 15 times shorter than this interval. The material is usually evaporated simultaneously from all charged evaporators (3) with overlapping of the molecular flows in the condensation zone. The method can be used for development of homogeneous semiconductor layers of great length and width on a flexible substrate, the layers having a predetermined composition and being of fractioned material. <IMAGE>

Filed: 1979-06-23
Abstract: Screening apparatus comprises an upwardly-inclined conveyor (14), with a hopper (10) and screen box (not shown) mounted respectively at the lower end and the upper end thereof. Discrete material fed into said hopper is passed onto the conveyor to be carried up to the screen box for separation by screens into finer and coarser fractions. Fractions greater than a particular size can be removed from the discrete material by an inclined grizzly bar screen (not shown) mounted over the hopper mouth. The spacings of the bars of said bar screen cannot practically be reduced beyond a predetermined limit, otherwise clogging occurs. To remove oversize fractions passed through the hopper, but not required for grading, a downwardly-inclined screen (11) is mounted between the hopper outlet and a feed boot (13) at the loading end of the conveyor with the lower end portion of the screen extending beyond the feed boot so that fractions too coarse to pass through the screen are deposited clear to the lower end of the conveyor. <IMAGE>
