Patent ES-404853-A1 (ES)
Title: Manufacture of chenille yarn
IPC: D04D3/00
Filed: 1972-07-04
Abstract: Two chenille yarns each composed of at least two core threads twisted to secure projecting short lengths of chenille effect material are produced simultaneously on a machine which continuously supplies two individual core threads from bobbins mounted in a head through a stationary tubular spindle to a mandrel. One or more threads of chenille effect material are supplied from a bobbin that is mounted at a distance from the head via a stationary thread guide to a rotating thread guide arranged below and laterally of the core thread bobbins on a rotating hollow spindle surrounding the stationary core thread spindle. The rotation of the lower thread guide causes the chenille effect thread to rotate and spin out in a balloon shape around the core thread bobbins in an unobstructed tubular space provided. The rotating thread is wound in a spiral around the core threads on the mandrel and two further core threads are applied to the outside of the spiral from further core thread bobbins. The spiral is cut and the two pairs of core threads with chenille effect material between them are twisted into the desired yarn. The core thread spindle is kept stationary by magnetic attraction to an adjacent fixed portion of the machine across the unobstructed tubular space. The chenille effect thread bobbins can be replenished without halting the machine.
Patent ES-406295-A1 (ES)
Title: Needle-supporting mechanism for pile fabric-producing circular knitting machines
IPC: D04B15/06
Filed: 1972-09-01
Abstract: Needles are supported by a needle-supporting means closely adjacent to the sinkers against bending in response to pull of pile loop yarn during sinker retraction. When the sinkers are integral with a pivotable lever, an arcuate lever surface concentric with the lever pivot is engageable by an intermediate guide which also engages a portion of the reciprocable needle stems to deter bending of the needles. The needle-supporting ring adjacent to the sinkers may have deep notches forming guideways for swinging portions of the sinker levers. Sinkers translated linearly by a pivotable lever engaging a sinker plate ear are separated by radial partitions carried by the needle cylinder. Such partitions have upper edge slots adjacent to upper ends of the needle stems to receive a complementally slotted needle stem bearing ring. The needle-supporting ring may be segmented.

Title: Aircraft transporter
IPC: B64C39/04
Filed: 1973-04-11
Abstract: An aircraft comprises a plurality of wings. Each of the wings has a leading edge and a trailing edge and upper and lower surfaces defining an airfoil portion which produces a lifting force when the wing is moved through the air. At least a portion of the trailing edge of each wing is configured to define a semicircle. A power-driven rotor is mounted for rotation in the semicircle and has generally radial blades extending into close proximity with the semicircular surface portion of the trailing edge of the wing and arranged to produce a downward air flow at the trailing edge. The radial blades rotate in a plane that intersects the semicircular portion of the wing trailing edge, and increase the velocity of air flow across the upper surface of the airfoil portion and decrease the velocity of air flow across the lower surface of the airfoil portion thereby increasing the lifting capability of the airfoil. The tips of the rotor blades are located so that when they are in proximity to the trailing edge of the wing, the upper portion of each tip is below the upper edge of the semicircular portion of the wing trailing edge and above the lower edge thereof. The axis of rotation of the rotor corresponds approximately with the axis of the semicircle and may be canted relative to the forward direction of aircraft movement to provide a component of forward thrust. The wings are supported in a tandem, horizontally spaced relation so that a rotor located along the trailing edge of one of the wings increases the downward flow of air relative thereto and also increases the downward flow of air relative to the other wing, whereby each rotor associated with each wing augments or magnifies the downward flow of air produced by each other rotor so as to further produce additional lift for the aircraft. In addition, lighter-than-air bouyancy units may be connected to the opposite ends of each of the wings so as to further provide a lifting force on the aircraft.

Patent ES-465399-A1 (ES)
Title: Sewing machine having an oil filter
IPC: F16N39/06
Filed: 1977-12-23
Abstract: A sewing machine includes a housing having an oil pan portion defining an oil reservoir with a filter supported on a wall of the sewing machine housing in a position above the reservoir. A pump is employed to direct the lubricating oil upwardly through a pipe connection into the top of the filter and a portion of the oil which is pumped is circulated through a small size tube in a continuous manner such that it is deflected against a viewing glass at the top of the sewing machine and drops down into the operating mechanism contained in the sewing machine housing. In addition, a portion of the oil which is pumped into the filter passes through a removable filter cartridge and into the interior of the filter. Before it is passed to any of the bearing parts of the main shaft, it is directed through a top opening in an upstanding pipe of an insert in the filter and downwardly through the pipe at the interior of the filter after having been filtered by passing through the filter material of the filter from the outside part of the filter housing and is then fed under pressure to the various bearing surfaces. The filter housing also includes a drain opening at the lower end thereof which is arranged so that it is closed by insertion of a filter with an annular sealing cap and its sealing member so that it covers the drain opening when the filter element is in an operative position inserted in the filter housing. When oil is to be drained, the filter element is removed upwardly to uncover the drain opening first so that little, if any, unfiltered oil will be able to move downwardly through the pipe having the inlet for the force feeding of the bearings.
