Title: Improvements in or relating to spraying liquids
IPC: B01F15/04
Filed: 1962-07-27
Abstract: In a method of and apparatus for applying a foamed material to a surface, flowing fluids (which may be liquids, or a gas and a liquid, or liquids) are first mixed, their pressures being first equalized as shown in Fig. 1 of Prov. Specification 27292/61, a pressure imparting liquid is fed from a container 7 where it is maintained at constant level, while a second liquid is fed from a bird fountain 1 to a container 4 adjusted to float in the first liquid at a depth at which the levels of the two liquids are the same. Alternatively pressure equalization may be carried out by means of a flexible diaphragm 16 as shown in Fig. 1 of Prov. Specification 31575/61 this arrangement may be modified to impart pressure to more than one diaphragm and liquid (see Fig. 2, not shown, of the same Specification) and the pressure imparting fluid (which may be a gas) need not be mixed with the others. Several such devices may be employed in series or parallel so that a multiplicity of fluids may be dispensed under the action of a single pressure imparting fluid. A further device for equalizing pressure may comprise containers 70, 73, Fig. 11, with a connecting pipe 72 the container 73 is first filled and sealed and the pressure-imparting liquid then admitted to container 70, when container 73 will become equally pressurized. Mixing in proportions. After pressure equalization the fluids pass to a metering and mixing device which may be a chamber 6 where they flow from jets the number and orifice sizes of which are related to the proportions required the proportions may also or alternatively be adjusted by valves 9. The mixing chamber may be maintained under a reduced pressure by a delivery pump. Another metering and mixing device may comprise a plug cock, Fig. 6, on which the plug 54 may be rotated to admit two liquids from chambers A, B through a selected number of orifices 1 to 20 to a discharge outlet 58. Spraying. The apparatus may be used to dilute a foam-forming liquid supplied to a spray lance for cleaning purposes as shown in Fig. 3 of Prov. Specification 27292/61 diluted or concentrated foamable liquid is supplied by the pump 25, water by the pump 34 and air by the compressor 29. By suitable adjustment of the valves 27, 30, 32, 35 the operator can supply either foamed or unfoamed liquid or air or water separately or a mixture of air and water. Fig. 4 of the same Specification shows a lance having twin spray nozzles 40. The foamable liquid is supplied to pipe 26 and air, water or a mixture of air and water to pipe 31. The two-way valve 43 and by-pass 47 enable the foamable liquid to be directed through the foaming chamber 45 which contains a foaminducing labyrinth material 46, or to be supplied direct to the nozzle 40.

Patent ES-361359-A1 (ES)
Title: Pressurized spray device
IPC: B65D83/14
Filed: 1968-12-12
Abstract: A pressurized dispensing container 14 has a chamber 12 which fills with propellant when the container discharge valve is open, and releases the propellant through the discharge valve nozzle 96 to clean it when the valve is closed. Chamber 12 is permanently connected to the valve stem bore 74 and nozzle 96 by a port 68, which also communicates with the container propellant space through port 62 when the valve stem is depressed. In the depressed position of the valve stem, material is discharged from the container via dip tube 90, valve stem bore 74, port 64, channel 49 and a port (66), Fig. 2 (not shown), also communicating with channel 49 in the open position of the valve stem and opening into valve stem passage 74, a partition 54 preventing communication between ports 64 and (66) in the closed position of the valve stem. In Figs. 5 to 10 (not shown), alternative arrangements of valve stem ports and sealing lands in seal 40 are provided to give simultaneous discharge of material and propellant, as in Fig. 1, and discharge of material only.
Patent ES-366064-A1 (ES)
Title: Combined fluid impellers and self-sealing closures
IPC: F04D29/36
Filed: 1969-04-02
Abstract: A fan impeller has adjustable blades 58 which assume the closed position shown when the impeller is stationary. However, when the impeller is rotated the blades are moved into their operative open positions by a pair of centrifugal weights 74 which move radially-outwardly about pivot pins 70 to partially rotate a control member 68 through pin-and-slot connections 76, 78 and thereby move the blades through arms 66. The degree of opening of the blades can be controlled by adjustable abutments 86 for the weights 74. Compression springs 82 bias the weights into their radially inner positions. The blades may instead be adjusted by an axially-movable control member. The impeller may be rotated in the reverse direction to reverse the flow therethrough. If, however, the impeller is to be rotated in one direction only the blade pivot shafts 60 may be offset from the control axes of the blades.

Patent ES-443747-A1 (ES)
Title: Information transmission system
IPC: G11B20/22
Filed: 1975-12-22
Abstract: The influence of disturbances such as tape noise, distortions or dropouts is to be drastically suppressed. For this purpose, an information signal and a compensation signal are read out from a recording medium. The compensation signal corresponds to the unwanted signal which has entered the information signal during its recording. The information signal and the compensation signal are contained in recording channels (S1, S2). The channels S1, S2 may be contained in separate tracks or as separate frequency bands in one track. During the recording, the input signal is recorded in the first channel (S1). The recorded signal is read out and is fed with the input signal, time-delayed in the time-delay element T, to a comparator device (A). The output signal of the comparator device reproduces the error in the recorded signal it is recorded in amplified form in the second track (S2) as a compensation signal. During reproduction, the information signal of the first track (S1) and the compensation signal of the second track (S2) are fed to an adding circuit (C). The output signal of the adding circuit (C) is free from the above-mentioned disturbances.
