Patent ES-468012-A1 (ES)
Title: Apparatus for the purpose of avoiding pressure drop between a gaseous or vaporous phase and a liquid phase
IPC: G21F9/08
Filed: 1978-03-18
Abstract: The apparatus comprises a first chamber in which there is present a gaseous or vaporous medium under pressure and a second chamber which is predominantly filled with a liquid medium under a pressure independent from the pressure in the first chamber. In addition to these two chambers an intermediate chamber is filled in normal operation with substantially the same gaseous or vaporous medium at substantially the same pressure as present in the first chamber. The first chamber is connected through ducts via the intermediate chamber with the second chamber and at normal operation an unavoidable predetermined pressure drop is caused between said intermediate chamber and said second chamber. The pressure regulation is effected by a piston-operated shut off device adapted to assume an open and a closed position which device is disposed between the first and second chamber. The pressure present in the second chamber through the duct means will act on one end of the piston by means of the liquid medium present in the second chamber. The shut-off device is thereby moved into the normal open position. The pressure present in the first chamber by means of the connecting duct acts on the other end of the piston and will cause the shut-off device to move into the closed position if the pressure differential between the two pressures exceeds the predetermined pressure drop by a predetermined value. This will close the shut-off device and thus prevent an overrun from the first into the second chamber because of an excessive pressure drop in the second chamber.

Patent ES-480789-A1 (ES)
Title: Device for stacking articles in layers on a pallet.
IPC: B65G57/24
Filed: 1979-05-22
Abstract: Objects to be stacked on a pallet or packaged without using a pallet, are transported by a conveyor to an inlet roll track where the objects are assembled into rows, from the inlet roll track a row of the objects is transferred to an intermediate support member where a layer of rows of the objects are collected and then picked up by a forklift device for movement to a pallet or a stack support. The inlet roll track is made up of a number of rollers which can be driven at variable speeds with the rollers most remote from the inlet to the inlet roll track moving at the lowest speed. Alternatively, the rollers of the inlet roll track can be arranged in groups with each group operating at a different speed and capable of being switched on and off separate from the other groups. The stack support can be moved vertically so that the forklift device places each layer on it in about the same horizontal plane as the stack is built up.

Patent ES-8201735-A1 (ES)
Title: Method and device for the non destructive testing of spot welds.
IPC: G01N3/00
Filed: 1980-12-12
Abstract: The present invention relates to method and to an apparatus for the non-destructive testing of spot welds and the determination of the diameter of a spot weld. The testing method comprises subjecting the welds (2) to a mechanical test using a pneumatic hammer and during the test the so-called "stuck" welds are destroyed. The remaining welds then undergo a punctiform inspection using a rheometric method. This method consists of creating a potential difference between the supply electrodes (10), of which there are even numbers in contact with the weld (2). Measuring electrodes (8) located in the vicinity of the supply electrodes make it possible to obtain a resulting quantity of the different voltages measured. After calibrating the resulting value of the voltages makes it possible to deduce therefrom the diameter of the weld and consequently its efficiency. Application to the determination of the diameter of a spot weld.

Title: Moving float liq. level indicator for vehicle fuel tank - has spring to intercept and counterbalance float at end of travel
IPC: G01F23/68
Filed: 1983-05-09
Abstract: The device indicates the level of a liquid in a reservoir, in particular, the fuel level in the tank of a vehicle. It has a float with a sliding electrical contact which slides in a tubular element which is placed inside the tank. A guiding element for the float has an electrical resistance on which the sliding contact slides. A fixed electrical contact is placed at the lower end of the tube and cooperates with a moving electrical contact on the float. The lower end of the tube has an elastic mechanism such as a spring which may also be the fixed contact and which intercepts the float at a predetermined distance from the base. The mechanism balances the weight of the float when it is found in a first end of travel position at the base. There may also be a second elastic mechanism at the upper end of the tube which intercepts the float at a predetermined distance from the upper wall of the tube and completely balances a hydrostatic thrust equal to the weight of the volume of liquid displaced by the float when it is found in a second end of travel position.
