Title: Direction indicator systems for road vehicles
IPC: B60Q1/38
Filed: 1967-12-20
Abstract: In a direction indicator system for a road vehicle having a manually operable direction indicator switch 11 (Fig. 1), resilient means urging the direction indicator switch to its neutral position and electromagnetic means 26 operable on movement of the direction indicator switch to either of its operative positions for maintaining the direction indicator switch in its operative position, a cancelling switch 22, 23 operated in use by a part 34 moving with the steering wheel of the vehicle breaks the circuit to the electromagnetic means 26 on completion of a turn and means are provided for holding the operating member of the cancelling switch out of the path of the part 34 except when the direction indicator switch is in an operative position. When the direction indicator switch 11 is turned to give a right-turn signal, the movable switch contact 32 bridges contacts 12, 13 so as to supply the right signal lights 24 from a flasher 18. Also the movable contact 33 bridges contacts 15, 17 which energizes electromagnets 26, 27 and 28. The electromagnet 26 maintains the indicator switch in its operative position until a switch 22, which is operated by a projection 34 rotatable with the steering wheel, is opened on completion of a turn. The electromagnet 26 is then de-energized and the direction indicator switch is returned to its neutral position by resilient means not shown. The ignition switch 21 has to be closed for the turn signalling system to function. Steering cancellation switch.-The electromagnets 27 and 28 form part of the cancelling switch 29 (Fig. 2), and when energized move a plunger 37 against a spring 47 so that a resilient portion 43 on the end of the plunger is moved into the path of the projection 34 which is rotatable with the steering wheel. As the plunger moves the resilient portion 43 to its operative position the contacts 44, 45 are parted so as to open switch 31 and de-energize the coil 28. Alternatively the switch 31 may be formed as a slider carried by the end 42 of the plunger which engages a conductive strip in the inoperative position and rests on an insulator to break the circuit to the coil 28 in the operative position. The resilient portion 43 is spring biased to a central position and is angularly movable in either direction and operates movable contacts of the switches 22, 23 mounted on a rotary member 41.

Title: Methods of Washing Vehicles
IPC: C11D7/06
Filed: 1969-12-18
Abstract: 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.

Patent ES-401730-A1 (ES)
Title: High frequency automatic gain control circuits
IPC: H03G3/30
Filed: 1972-04-13
Abstract: A common base amplifier used for high frequency amplification has an automatic gain control voltage applied thereto to vary the gain in a reverse mode. As the gain of the transistor is decreased, a unilateral current conduction device, coupled to the emitter electrode or input of the amplifier, is caused to conduct. The conduction of the unilateral device causes the voltages between the electrodes of the amplifier to remain constant, while further causing additional impedance shunting of the transistor to maintain the input impedance of the amplifier relatively constant during AGC operation.

Title: Gyratory crusher having anti-spin means for head
IPC: B02C2/04
Filed: 1972-12-15
Abstract: A gyratory or cone type crusher having a generally conical crushing head rotatably mounted on an upright eccentric so that the head is gyrated upon rotation of the eccentric. The stationary frame of the crusher has a crushing bowl including a concave which surrounds the crushing head and cooperates with it to form an annular crushing chamber. The material such as rock, ore, or other material to be processed is distributed to the crushing chamber by feeding the material into a hopper above the cone and concave, which material then falls into the annular space between the conical shaped head and the concave. The eccentric is continually rotated to cause the head to gyrate in respect to the concave, thereby effecting crushing action upon the material. Means are provided in the present crusher and located between the eccentric and the head for rotating the crusher head in a direction opposite to that in which the eccentric rotates, whereby the head is maintained rotationally stationary in respect to the concave at a no-load condition.

Patent ES-411576-A1 (ES)
Title: Method and apparatus for space dyeing strand material
IPC: D06B11/00
Filed: 1973-02-13
Abstract: The disclosed method and apparatus involve pulling a strand, e.g., a yarn, past a portion of the periphery of the wheel which is rotated so as to constantly pick up dye liquid from a bath into which a lower segment of the wheel extends. An air jet is directed toward the running strand across a peripheral segment of the wheel so as to blow dye liquid from the wheel onto the strand. A shield having apertures therein is moved so as to alternately align apertures and solid areas with the air jet whereby the dye liquid is blown onto the yarn only when an aperture in the shield is aligned with the jet to thus produce a strand having spaced dyed and undyed portions.
