Patent ES-423118-A1 (ES)
Title: Helicopter haul-down and securing system
IPC: B64F1/02
Filed: 1974-02-01
Abstract: A system for hauling down and securing a helicopter or the like with a haul down cable loop which attaches at one point to the helicopter and at another point to a deck winch. The cable loop passes through the deck at two separated locations via swivel sheaves so that while the helicopter is being hauled down, the cable acts like a single cable, exerting a downward force and, after the helicopter is on the deck, exerts both vertical and lateral forces to secure the helicopter on the deck. The cable loops over a draw sheave below deck, which is connected to the winch by a draw line so that the haul down cable is free to run over the draw sheave to equalize tension during haul down. After landing, the sheaves and cables would be locked by suitable braking means so that the two cables from the helicopter to the deck-mounted sheaves can restrain the helicopter.

Patent ES-452972-A1 (ES)
Title: Internal division actuation of ventilated floppy disk stack
IPC: G11B17/02
Filed: 1976-11-03
Abstract: A hollow tubular actuator device operates through an enclosure formed by aligned holes in multiple floppy type storage disks. The disks, separated by interposed ventilating spacers, are clamped between inflexible end plates in a closely spaced continually rotating stack assembly. The actuator preferably rotates with the stack and translates axially relative to the disks and spacers. The actuator has a slotted opening for transmitting variable pressure to a selected spacer (address) in the stack and thereby varies the aggregate pressure equilibrium in the stack due to centrifugal air flow. This acts to deflect the orbits of disks peripherally, on either side of the selected address space, forming a gap useful for obtaining external access to otherwise inaccessible storage surfaces adjacent the selected space.

Title: Machine to strip wool from animal skins - is easily loaded and strips entire surface without damaging skin
IPC: C14B1/12
Filed: 1977-04-21
Abstract: The machine used a conveyor having twin parallel chains with transverse pivots on which are fixed spaced carriers for skins. Each carrier is in the form of a flat work table and skin is folded to saddle the leading edge of the table and trail back on opposite faces of the table. The table conveys the skin over a vertical run, upwards between rotary stripping cylinders. The table faces are covered by an endless belt which is given a limited longitudinal movement as the table passes between the stripping cylinders this moves the unstripped, leading edge of skin on to one face of the table for stripping. The chain pivot fixings for each table are such that the table remains in the same plane as the chains on straight runs of the conveyor. As the chains pass around a pair of sprockets, the table leading edge moves radially outwards frm the sprockets' axis. This takes the leading edge clear of a skin-clamping roller which is tight against the leading edge on straight runs. Movement of the table belt is pref. obtained by fitting a toothed pinion on the front roller of the belt and arranging for the opinion to engage a short length of rack as the table passes the stripping cylinders.
