In a further embodiment, Fig. 5 (not shown), a third container (31), within the outer container 1, communicates with the valve housing through a second ball valve (32). The outer container in this embodiment may contain propellant or a propellant and a liquid to be dispensed. In the former case a dip tube (20) communicating with the valve housing has a plug (31) in its lower end and in the latter case the plug is replaced by a ball valve. The outer metal container may contain one, two or three flexible containers. Two separately held liquids may be hydrogen peroxide, and sodium hypophosphite or potassium sulphite and lathering ingredients.

Patent ES-408997-A1 (ES)
Title: Method and apparatus for providing sequential turn-on and turn-off control signals for a chopper
IPC: H02M3/135
Filed: 1972-11-25
Abstract: A counter counts in response to provided timing signals, and a first plurality of gates respond to a first predetermined count for providing a turn-on signal for the chopper. A second plurality of gates respond to a second predetermined count to provide a signal manifestation indicative of the time interval during which the turn-off signal for the chopper may be provided. A comparator compares a status signal, indicative of the desired signal level of operation of the chopper, with a ramp wave. When the signal level of the ramp wave is substantially at the same signal level as the status signal a control signal is generated. The latter control signal is provided to the input of a shift register and in response to the timing signals, the control signal is shifted through the shift register. When the shift register stores a selected signal indication, the turn-off pulse for the chopper is provided. There are also included means for inhibiting the provision of the turn-on and turn-off signals in the event the chopper is not operating at selected performance levels.

Title: Xerographic image transfer apparatus
IPC: G03G15/00
Filed: 1974-01-11
Abstract: A shield for preventing premature transfer of xerographic toner images from a photoconductive plate to a sheet of final support material, both of which are being moved at synchronous speeds through a transfer zone beneath a corona generating device. The shield, which is made up of a grounded plate having a thin dielectric coating thereover, is positioned within the generator ion stream to prevent the charged ions from reaching the support material prior to its being placed in contact with the photoconductive plate.

Patent ES-455892-A1 (ES)
Title: Method of manufacturing base plate with photoconductive layer
IPC: G03G5/00
Filed: 1977-02-14
Abstract: A slightly conductive coating (2) is applied to the surface (1) of a c.r.t. and covered with a layer of the photoconductive material (3). This is uniformly charged. At any conductive blemishes e.g a dust particle (4), or a pinhole in the layer (3) the charge leaks away through the first coating (2). A developer containing the same photoconductive material similarly charged is then applied. The charged particles are repelled from the charged areas and driven towards the blemishes, where they adhere. The method may be extended to deal also with non-conductive blemishes, though these are rarer. The surface is charged and exposed to light. The charge remains only on the non-conductive blemishes, which then accept a developer containing the photoconductive material, as before.
