Patent ES-333721-A1 (ES)
Title: Coaxial cable forming apparatus
IPC: H01B13/26
Filed: 1966-11-12
Abstract: A forming apparatus for imparting a transverse curvature to a longitudinally moving corrugated strip by passing it through a plurality of stages each comprising a pair of forming rolls, the rolls forming each pair being freely rotatable and having curved peripheral forming surfaces, is characterized in that the average radius of curvature imparted to the ribbon by the first pair of rolls is substantially equal to the product of the number of stages and the desired final radius and the average radius of curvature imparted by each succeeding stage is substantially inversely proportional to the number of the stage, the final stage imparting the curvature having the desired final radius. Thus, for example, with five stages the profile radius of each stage is respectively 5, 5/2, 5/3, 5/4, and 1 times the desired radius of the tube. A transversely corrugated strip 12 of copper bonded to tin-plated steel is given a transverse curvature by passage between pairs of rolls 38, 40 and 44, 46. A conductor 16 carrying spacers is fed down a tube 20 into the thus-formed trough. Pairs of rolls 52, 54, 60, 62 and 64, 66 then bend the strip 12 up into tubular form about the conductor 16. The rolls are adjustable and have ridges formed thereon against which the edge of the strip 12 abut. The profiles of the rolls 44, 46 may have smaller radii of curvature at the edges that at the centre. The strip thus formed into tube form 26 may then pass beneath a vertical wheel 136, Fig. 10, having a knife edge 140 engaging the edges of the strip to position the seam. The edges are then overlapped by rolls 76, 78 and the tube sized by rolls 76, 78, 80, 82 and 88, 90 before soldering the seam.
Patent ES-342472-A1 (ES)
Title: Apparatus providing constant adjustment of the partial current in a non-linear resistance network
IPC: G06G7/26
Filed: 1967-06-30
Abstract: In a circuit (Fig. 2) producing a non-linear voltage function of an input current function I, e.g. for operating a maximum current relay with delayed release dependent on current, a non-linear resistance network 1 in series with a variable resistance 4 accepts current I 2 to produce output voltage drop V, and a shunt comprising resistance 2, collector/emitter circuit of transistor 5, and variable resistor 3 accepts current I 2 the transistor base being connected to the junction of 1, 4. Then input current I = I 1 + I 2 and for all values of input so that the non-linear network current is maintained constant independently of input current. In modifications (Figs. 3, 4, not shown) the base/emitter drop in the transistor is compensated by a diode in series with resistance 4, or by a second transistor with collector/emitter circuit in series with 4 and base interconnected with base of the first transistor for energization over a further resistance from input current. Plural non-linear networks may be connected in parallel and shunted by a common transistor/resistance circuit.
Patent ES-343867-A1 (ES)
Title: Hydraulic suspension system having a plurality of accumulators
IPC: B60G17/056
Filed: 1967-08-05
Abstract: An hydraulic piston-cylinder suspension unit is combined with a plurality of hydropneumatic accumulators B 1 ... B n , Fig. 4, each at a successively higher pneumatic pressure, and communicating with the cylinder 1 via slide valves T 1 ... T n-1 responsive to the suspension pressure such that the hydraulic fluid enters successive accumulators as the hydraulic pressure exceeds each pneumatic pressure. As the suspension pressure increases, due to loading, the slide valve 25, Fig. 1, is forced to move so as to close the connection at 32 with the low pressure accumulator 5 and the fluid enters the higher pressure accumulator 8 through throttle means 37. Simultaneously, accumulator 5 communicates via bore 27 and spring valve 34 to a fluid reservoir 18 to prevent build-up of pressure in 5.

Title: Load-dependent braking device for conveying systems
IPC: F16D63/00
Filed: 1973-07-26
Abstract: A load-dependent braking device for conveying systems having a primary brake with a fixedly adjusted braking moment and a secondary brake with variable braking moment, the braking moment of the secondary brake being adjusted in dependence on the loading moment acting upon a drive device or machine for the attainment of a braking deceleration or retardation independent of load. A rotatable brake part of the primary brake is rigidly connected with a fixed brake part of the secondary brake. A rotatable brake part of the secondary brake, which can be pressed by brake linings or pads against the fixed brake part through the action of spring pressure, is raised or lifted-off as a function of the change of speed occurring during the braking of the drive machine by a rod or linkage arrangement pressed by means of spring force against a setting cam. The setting cam is arranged on a flywheel or inertial disk mounted to be freely rotatable upon a drive shaft of the drive device and actuates the rod arrangement in proportion to the angle of displacement between the flywheel disk and the drive shaft in opposition to the spring force.

Title: Railway track tamping machine
IPC: E01B27/13
Filed: 1976-06-18
Abstract: Track-tamping machine (1) for compacting the ballast beneath a plurality of sleepers (S1, S2, etc.) of a track, having tamping tools (12-15), mounted on the tamping-tool frame or an intermediate carrier (18), and vertical-adjustment, vibration and feed drives (22 21 19, 20) assigned to said tamping tools. In each case two tamping tools (12, 13 14, 15), which can be adjusted with respect to each other in the track longitudinal direction and can dip together into a space (F1, F2) between the sleepers, form an expanding tamping-tool pair (16, 17).

Specific tamping is thus made easier, even when the distances between sleepers vary. The two expanding tamping-tool pairs or groups are mounted on a common tamping-tool carrier (18) and are connected to a drive (22) for common vertical adjustment.

Title: Belt centering and replacement mechanism for belt sanders and the like
IPC: B24B23/06
Filed: 1978-09-28
Abstract: The front idler roller of the belt sander is mounted by a yoke for swinging movement in a plane containing the axes of both the drive and idler rollers and for shifting movement along a path generally toward and away from the drive roller. A transversely disposed shaft mounted by the tool housing has a cam formation at one end thereof received within an opening formed in the yoke the cam is captured in this opening formed in part by a cam follower. The shaft is mounted for axial and rotational movements. Rotation of a first knob on the other end of the shaft causes the latter to move axially thereby to swing the idler roller for centering of the belt. Rotation of a second knob, concentric with the first knob and also mounted on other other end of the shaft, causes the shaft to rotate thereby activating the cam for shifting the idler roller toward the rear roller for easy belt replacement.

Title: Self-aligning clutch release bearing
IPC: F16D23/14
Filed: 1979-03-27
Abstract: A self-aligning clutch release bearing assembly including a tubular bearing carrier and a anti-friction bearing assembly encircling the bearing carrier and supported thereon by means of an annular spring washer which enables relative restricted shifting movement of the axis of the bearing relative to the axis of the bearing carrier to compensate for eccentricity in the axis of rotation of a clutch assembly and a guide member on which the clutch release bearing assembly is mounted. In addition, the spring washer permits restricted angular displacement of the axis of the bearing assembly relative to the axis of the bearing carrier to compensate for angular misalignment between the clutch assembly and axis of reciprocation of the clutch release bearing assembly. The bearing carrier further includes coacting means for engaging a clutch actuating device such as a actuating fork for preventing relative rotation of the clutch release bearing assembly whereby an adjustment for radial misalignment by the bearing assembly is appropriately maintained during subsequent clutch actuation cycles.
