Patent ES-359016-A1 (ES)
Title: Handling device
IPC: B65G7/06
Filed: 1968-10-10
Abstract: A device for transporting a load 13 comprises an inflatable chamber 1 positioned between the load and the ground 11, an upper wall 12 of the chamber being secured to a load-supporting platform 6 mounted on legs 14, 15, and inextensible members 17 articulating the wall 12 to a parallel lower wall 10 of the chamber 1, inflation of the latter causing the wall 10 to engage the ground and move the load and platform upwardly and to the left in the Figure. With deflation of the chamber, the legs 14, 15 again engage the ground and a spring 16 pulls the lower wall 12 of the chamber to the left to assume the position shown, wherein the device is ready for another cycle, inflation and deflation being manually controlled by a valve 4 on the platform. In the embodiment of Figs. 8 and 9 (not shown), a platform is mounted on four inflatable chambers in square formation, each pair of diagonal chambers having their inextensible members spring loaded for platform movement in opposite directions, one diagonal pair of chambers when inflated taking the place of the platform legs of the first embodiment. In the embodiment of Figs. 10, 11 (not shown), a load platform is provided with a plurality of inflatable chambers such that movement of the platform in four directions at right angles is obtainable. Alternatively, the platform may be inverted so that a load is moved by direct contact with the chambers. In the embodiment of Figs. 13-16 (not shown), pneumatic traction rams and cables within each inflatable chamber control movement between the upper and lower surfaces of the chamber so that during inflation and deflation the chamber moves from an inclination one way to an inclination the opposite way. In the embodiment of Figs. 17-25 (not shown), the load platform includes retractable castors for positioning, and the inflatable chambers merely move up and down, an air bed being formed between the platform and the top of the chambers so that the platform can slide relative thereto during arcuate movement of the inextensible members as inflatable traction bags are operated. The latter comprise bags around which traction cables are wound, each cable being tensioned as its associated bag is inflated.
Patent ES-371468-A1 (ES)
Title: Composite selector switch and reversing switch for tap-changing regulating transformers
IPC: H01F29/04
Filed: 1969-09-12
Abstract: To reduce the lateral dimensions of a tap changer having a change-over switch for reversing the polarity of the tapped regulating winding with respect to the main transformer winding (thereby doubling the regulation obtainable with a given number of taps) and wherein the fixed contacts of the tap selector are secured on vertical insulating bars in a cylindrical arrangement, the three fixed contacts of the change-over switch are also mounted on vertical insulating bars arranged in the same cylindrical path. Fixed selector contacts, such as 5, 6, of the three phases U, V, W, are arranged on vertical bars 21 to lie on circular paths with even-numbered contacts 2 to 12 co-operating with wipers 24 and odd-numbered contacts with wipers 23. A drive wheel 41 alternately steps Geneva wheels 42 and 43 coupled to wipers 23 and 24 respectively. The spacing of the end contacts (such as 2 and 12) from the mid-value contact K (which is connected to the main winding) is greater than the mutual spacing between the tap contacts to allow for the greater voltage difference, and the wheels 42 and 43 have funnel-shaped slots (44, Fig. 7, not shown) providing the smaller steps and straight slots (45) providing the two larger steps. In the larger spaces between bars 21 supporting contacts K and contacts such as 2 and 12, further bars 28 are fitted and carry outwardly-projecting change-over contacts + and - connected by leads 37 to the ends of the regulating winding. Insulating bars 32 carry arcuate bridges 30 and are pivoted concentrically with selector column 27 by means of arms 34, 35. A dog 46 on Geneva wheel 43 engages in and moves a slotted arm 49 on completion of a revolution of wheel 43, and a dog 49 on arm 34 couples this movement to the bridges 30 which are thus moved (as the wipers 24 engage the contacts K) to interconnect contacts K with the + contacts instead of the - contacts, or vice versa, whereby on completion of a tapping sequence the relative polarity of the regulating winding is reversed.

Patent ES-422904-A1 (ES)
Title: Cartridge clip and a machine for filling the clip with cartridges
IPC: F42B39/08
Filed: 1974-02-04
Abstract: A cartridge clip comprises an elongated channel-shaped body for receiving the rim ends of a group of cartridges and having side walls provided with inwardly directed flanges for engaging a groove at the rim ends of the cartridges. The body is pressure molded as a single piece of resilient material such that the rim ends of the cartridges can be introduced onto the clip in a direction transverse to the body by a snap action. A rigidifying rib extends along an outer surface of a base of the body which has a central longitudinal depression on its inner surface. Lateral stops are provided on the side walls at the ends of the channel to prevent accidental escape of the cartridges and external abutments on the side walls limit the insertion of the clip into a magazine guide. A machine for filling such a cartridge clip comprises an intermittently rotatable annular drum provided with axial sets of radial bores. An inclined plate dispensing station dispenses cartridges into the bores so that their rim ends and nose ends project respectively outwardly and inwardly from the drum, and a dispensing supply chute deposits a clip on the cartridges in each set of bores. A notched pressure roller presses the clips transversely onto the rim ends of the cartridges by a snap action and the filled clips are discharged from the drum by engagement of their nose ends with a fixed cam inside the drum.

Abstract: Apparatus for measuring a vessel's velocity relative to a reference location includes a transmitter on board the vessel for transmitting a coherent signal toward a reference location from where the coherent signal is reflected, and a receiver on board the vessel which includes at least two spaced-apart receiver transducers. The coherent signal transmitted by the transmitter is within a lobe range that is substantially common to the at least two receiver transducers, the signals reflected by the reference location comprising at least two acoustic signals that are similar in character but different in timing from each other, the difference in timing being a function of the distance in the direction of measurement between the spaced-apart receiver transducers and further being a function of the vessel's velocity, the received signals comprising reflections from every point on the reference location within the lobe range. Operating means is provided to operate on the reflected acoustic signals received by the receiver so as to generate a signal which is a function of the timing difference between the two signals and which is further indicative of the vessel's velocity relative to the reference location.
