Patent ES-385056-A1 (ES)
Title: Liquid supply pump
IPC: F02M37/02
Filed: 1970-10-30
Abstract: A pump assembly comprises a container divided into two compartments 14, 16, Fig. 2, each containing a respective pump 40, 50, e.g. of the centrifugal type shown. Liquid is drawn through a duct 18 and valve assembly 20 into compartment 14 by the suction created therein by pump 40, the suction also keeping the valve assembly 20 open via diaphragm 32 exposed to the closed chamber 14 and to the chamber 16 which is permanently vented to atmosphere at 17. The valve assembly also includes a non-return valve 22. The pump 40 delivers the liquid through conduit 46 into compartment 16 from where it is discharged via conduit 58, Fig. 5, flow-metering valve 82 and outlet 59. Compartment 16 contains a float assembly 60 which opens a valve (70), Fig. 3 (not shown), to directly communicate the compartments 14, 16 with each other through a passage (76) in partition 13, when the liquid level in compartment 16 reaches a predetermined value. Thus, the suction in compartment 14 is neutralized causing closure of valve assembly 20 until the liquid level falls.

Patent ES-406033-A1 (ES)
Title: Controllable force method and system of driving piles
IPC: E02D7/06
Filed: 1972-08-22
Abstract: A method and system for determining the magnitude of a driving force being exerted on a substantially rigid object being driven into the earth, such as a pile, and controlling the magnitude in response to that determination. Where the pile driver utilizes a massive piston weight reciprocating in a cylinder and bouncing upon pressurized fluid in a chamber, the force magnitude is determinable by sensing pressure values occurring in the bounce chamber. Force control is obtainable by regulating the flow of pressurized fluid into the bounce chamber in response to the determination. Peak pressure values are sensed by pressure gauge or transducer means to determine the peak values of driving force being exerted on the top of the pile and control of the pile driver operation can be manually or automatically obtained.
Patent ES-409699-A1 (ES)
Title: Toner usage sensing system
IPC: G03G15/08
Filed: 1972-12-16
Abstract: A toner usage sensing system for an electrostatic reproduction apparatus which utilizes multicomponent developer material including electrostatically charged toner to develop electrostatic latent images on a photosensitive plate directly senses the amount of toner consumed by the reproduction process. Since the average toner body charge (coulomb/gram) is constant for a given desired toner concentration, the weight of the electrostatically charged toner consumed in sensed by measuring the charge removed from the developer material during the reproduction process. The developer unit containing the developer material is electrically isolated from the remainder of the reproduction apparatus and grounded through a single connection. The current in the ground connection returns charge to the developer unit sufficient to replace the charge removed and is sensed to obtain a measurement of the toner consumed. A measured amount of toner is added to the developer material when a preselected amount of charge has been sensed as being removed. In one embodiment, a DC motor drives the toner replenisher and rotates an amount proportional to the sensed current thereby providing a mechanical storage of the incremental amounts of toner removed on widely spaced reproduction runs.

Title: Tobacco smoke filter
IPC: A24D3/04
Filed: 1976-10-29
Abstract: Tobacco smoke filters wherein the products have both internal and external cavities, with the external cavities being of a limited nature so as to provide a substantially smooth outer surface for attaching conventional plug wrap without the need for an internal glue line. The external cavities comprise from about 5 to no more than 50 percent of the total outer surface of the inner filter member, preferably between about 20 to 30 percent. This enables the inner filter member to provide substantially uniform support to the overwrap. The outer cavities may be in the form of elongated, discrete, grooves, a knurled-like pattern or a continuous helical groove. The resultant filter has high filtration and correspondingly low pressure drop characteristics, with the technique of manufacture being such as to permit higher production speeds than with the prior art, resulting in lower manufacturing costs.
