Patent ES-8102309-A1 (ES)
Title: Valves and breathing apparatus incorporating such valves.
IPC: A62B7/04
Filed: 1980-06-20
Abstract: A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm coupled to a separate control member which lies in the path of a jet of gas which vents from a control chamber through an orifice, gas being continuously supplied to the control chamber. Deflection of the diaphragm in response to pressure changes in a second chamber caused by inhalation and exhalation of the user of the apparatus pivots the control member towards or away from the jet orifice to control the rate of venting from the control chamber and thereby vary the pressure within the control chamber. Flow of gas through the valve to the user of the apparatus is controlled by a flexible disc which in turn responds to the pressure in the control chamber. By employing a separate diaphragm and control member the former can be optimized for pressure-response while the latter can be optimized for valve-regulation by interaction with the gas jet from the control chamber.

Patent ES-8204897-A1 (ES)
Title: Failure compensated automatic kinescope beam current limiter
IPC: H04N5/59
Filed: 1981-01-29
Abstract: An automatic kinescope beam current limiter for a television receiver includes a source of derived beam current representative voltage, a keyed sampling circuit for developing an output beam current control voltage on a charge storage capacitor in response to the derived voltage, and an auxiliary current path including an impedance coupled between the output capacitor and the source of derived voltage. In a normal beam limiting control mode, the control voltage from the sampling circuit serves to modify the television signal in response to the derived voltage in a direction to limit excessive beam current. In an abnormal control mode such as when the sampling circuit is inoperative due to disrupted keying, current is conducted via the auxiliary current path in response to the derived voltage to modify the control voltage on the capacitor with a sense and at a rate for limiting excessive beam current, to thereby preserve beam limiting capability.
Patent ES-8201446-A1 (ES)
Title: Method of separating paper and plastics pieces and separating means therefor.
IPC: B07B4/04
Filed: 1981-02-06
Abstract: In an upward gas stream sifter for separating sheet-like pieces of paper and plastic in a wetted mixture, the gas is heated to at least 60 DEG C. in order to dry surface moisture on the plastic. The temperature of the gas is not so high that the plastic shrivels. This increases the difference in density between the pieces of plastic and wet paper, thus assisting the separation. Optionally some gas may enter the mixture feed duct through a gas permeable part of its wall, to prevent accumulation of mixture on the wall. If the mixture is derived from household rubbish and the plastic is mostly polyethylene the gas may enter the sifter at 120 DEG C. and leave it at about 70 DEG C.
