Patent ES-452138-A1 (ES)
Title: Control device for a sewing machine
IPC: H02P29/00
Filed: 1976-10-06
Abstract: The control device controls the sewing speed of a sewing needle automatically in a manner such that the temperature of the sewing needle, subjected to the influence of heat generated by friction with the material being sewn, does not exceed an adjustable predetermined value. Respective measuring members determine the temperature of the sewing needle and the temperature of a reference needle mounted at a location spaced from the sewing needle, and are connected to the input of a differential comparator circuit providing the differential voltage of the measuring members. A signal generator is operatively associated with the sewing needle and produces output pulses responsive to reciprocation of the sewing needle, to control connection of the output of the differential comparator circuit to the input of the sewing machine motor control. The reference needle is substantially identical with the sewing needle. A plurality of reference needles of different sizes may be provided, and brought selectively into the control circuit either mechanically or electrically in accordance with the size of the sewing needle being used.

The trusses are formed by making a grid of parallel longitudinal runners joined by diagonal cross wires which are then cut between adjacent pairs of runners to form separate trusses. The trusses are then joined by transverse wire runners forming a three-dimensional matrix.
Patent ES-458613-A1 (ES)
Title: Thread feeder for textile machines
IPC: B65H51/22
Filed: 1977-05-09
Abstract: A thread delivery device for a textile machine having a rotatable drum on which a thread issuing from a thread bobbin can be wound tangentially for forming an intermediate thread storage. The drum has a lower thread removal edge over which the thread can be withdrawn tangentially for permitting positive thread delivery. A thread guide member is stationarily positioned radially outside of the drum approximately at the level of the removal edge to guide the withdrawn thread. A thread control element is disposed in engagement with the withdrawn thread at a location between its engagement with the drum and the thread guiding member. The thread control element, which is movable transversely relative to the withdrawal path of the thread, is positioned approximately at the level of the removal edge of the drum and is maintained in this position by its engagement with the withdrawn thread so long as the normal working tension is maintained in the thread. When the tension in the withdrawn thread decreases, then the thread control element moves transversely of the thread path, either due to its own weight or due to the urging of a spring, downwardly into a position wherein the thread control element is disposed below the plane of the removal edge to prevent the slack thread from being reversely wound on the drum.
Patent ES-460614-A1 (ES)
Title: Piston type energy conversion machine
IPC: F01B3/00
Filed: 1977-07-11
Abstract: A piston type energy conversion machine such as an internal combustion engine in which the thrust of piston reciprocation is converted to nutational movement of a tube-like member journalled in a support which is driven in rotation about a primary engine axis. Also supported for rotation on the primary engine axis is a biconical element to which torque is transmitted by friction from the nutating member. The pistons operate in a plane which undergoes a swashing movement on a point at the intersection of the primary axis with the axis of nutation. Also the connection of the pistons to the nutating member is by way of linkage including swivel links which function to absorb the thrust of each piston power stroke.
