Patent ES-427851-A1 (ES)
Title: Stabilization of partitionable memory with flexible rotating discs
IPC: G11B17/34
Filed: 1974-07-01
Abstract: A random access memory with closely spaced ultra-thin continuously rotating flexible magnetic discs is stabilized while being partitioned by an airfoil blade. A shroud member having the form of a section of a cylinder controls air flow within and around the discs under steady state and disturbed conditions. A rigid reference plate controls air flow relative to one end of the disc aggregate. Flexible washer discs having varied diameters, retain the other end of the aggregate and operate as a variable rate spring to damp fluttering movements of the discs caused by operation of the partitioning mechanism. The hollow partitioning blade is adapted to supply slightly pressurized air between an external source and the partition interface. The air is emitted at a critical predetermined angle relative to the interfacing discs and directed at an angle to the entrained air flow within the interface. This serves to stabilize the discs which are not displaced by the blade but which have a tendency to flutter due to the turbulence produced by the partitioning action.

Title: Self cleaning heat exchanger circuit
IPC: F28G1/12
Filed: 1975-06-28
Abstract: An apparatus for continuously cleaning tubular heat exchangers during use is disclosed, including a separator for continuously circulating cleaning bodies through the heat exchanger along with the heat transfer-medium being employed. The separator thus recirculates the cleaning bodies along with fresh heat transfer medium while separating out a major portion of the heat-transfer medium withdrawn from the tubular heat exchanger, and includes means for withdrawing the cleaning bodies from a downstream portion of the separator and means for withdrawing the heat-transfer medium withdrawn from the heat exchanger from an upstream portion of the separator. The separator is preferably vertically disposed, so that the cleaning bodies are aided by gravity in reaching the downstream portion of the separator, and the cleaning bodies therefore do not impinge upon any screen for separating them from the heat-transfer medium. Baffle means are also provided in the upstream portion of the separator to assure low uniform velocity distribution of the heat transfer medium, and a check valve is provided in the downstream portion of the separator to prevent reversal of the flow of heat-transfer medium at the outlet port of the separator. In addition, means are also provided for maintaining a closed loop including the cleaning bodies free from pumps, including a Venturi disposed at the downstream portion of the separator, and where pumps are employed in the closed loop, a time demand or flow demand circuit for deactivation of the pumps at regular time intervals or at conditions of low demand is provided.

Means for synchronising the defibrillator and the compressor is provided comprising a pressure sensitive switch for synchronising the defibrillator and compressor such that defibrillating current is applied to the patient's heart only during a systolic portion of the compression cycle of the compressor, i.e. when the path between the internal and external electrodes is short and electrical contact between the electrodes and adjacent parts of the body is good.
Patent ES-488054-A1 (ES)
Title: Hydraulic auxiliary power steering
IPC: B62D5/06
Filed: 1980-01-31
Abstract: A control valve for a hydraulic booster steering system provides gradual control of inlet flow to the system pump to complete cut off of output, or by throttling of inlet flow to effect a pilot stream through the pressure pump. This occurs in the neutral position of the control valve during straight ahead steering. Where flow through the pump intake feed means is thus impeded, the pump simply cavitates in a known manner and to be of a type which is suction regulated, having a check valve means at the pressure outlet side. The advantage of cutting off inlet flow to the pump during straight ahead steering, or at least throttling of such inlet flow by a constantly open throttle passage, is to save energy otherwise wasted in heating the fluid.

Filed: 1980-02-06
Abstract: The communications system has each indoor unit, e.g. located in flats, provided with an electronic switch containing a capacitor which, when charged, switches the indoor unit on and when discharged switches it off. The outdoor unit e.g. at the main entrance to the block of flats, has a device to charge the capacitor when a call button is pressed associated with the desired indoor unit. After the call button has been released the capacitor's charge remains for a given time above the level required to switch on the indoor unit concerned. When another call button is operated this capacitor is discharged or maintained at its discharged level if it has not in the meantime discharged by natural leakage.
