Title: Hydraulically needling fabric of continuous filament textile and staple fibers
IPC: D04H5/02
Filed: 1979-11-30
Abstract: A lightweight composite fabric characterized by high retention of fiber content during initial laundering and exceptionally high strength as measured close to the edge of the fabric with cover and fabric aesthetics equivalent to conventional fabrics having 50% higher basis weight are produced by hydraulically needling short staple fibers and a substrate of continuous filaments formed into an ordered cross-directional array. The individual continuous filaments of the array are well spread and separated so that they have a spaced-apart relationship allowing interentangling of the short staple fibers with the continuous filaments to form more than about two reversals in the staple fibers per cm of staple fiber length between the faces of the fabric. The staple fibers have a linear density of less than about 0.3 tex per filament, are from about 0.5 cm to about 1 cm in length and comprise about 20% to about 50% of the weight of the composite fabric.

Title: Electronic ignition device
IPC: F02P5/155
Filed: 1980-01-11
Abstract: An electronic ignition device for use with an internal combustion engine is coupled between an ignition coil switch and a magnetic pick-up. The pick-up produces a cyclical signal A which is integrated and applied to a first comparator, the other input of which receives a threshold. The comparator output actuates the ignition coil switch. A logic circuit combines the output Z of a zero detector receiving the cyclical signal A with the output of the first comparator. The logic circuit output is integrated to provide a signal R indicative of actual ignition displacement, and which is compared with a signal RS representing the required ignition displacement. In a first embodiment this comparison takes place in a second comparator the output of which is fed back to constitute the threshold input of the first comparator. In a second embodiment the threshold for the first comparator is defined by RS, the signals R and I being combined before application to the first comparator. By means of such control loop variations due to manufacturing tolerances, etc, will not adversely affect spark retardation.

Title: Heat treatment apparatus
IPC: F26B13/02
Filed: 1980-08-01
Abstract: An apparatus for the heat treatment of a material passing through a plurality of treatment zones using a heated gaseous treatment medium conducted in a substantially closed circuit through these zones. A heat exchanger is associated with each treatment zone. The heat exchanger defines, in an operative relation with the respective treatment zone a medium discharge path and a medium replacement path which paths are arranged in a heat exchange relationship. The fractional portion of a treatment medium discharged from each treatment zone transfers its heat and energy to the fresh replacement medium. A throttle or flow control in the medium replacement path for each treatment zone permits individualized control of draft and medium turnover according to the different conditions prevailing in each zone. A filter is also provided to prevent impurities in the medium discharge flow path from entering the heat exchanger.

Patent ES-8307645-A1 (ES)
Title: Device for transporting ferromagnetic work pieces.
IPC: B65G54/02
Filed: 1982-11-30
Abstract: The transport device possesses holding magnets along a transport path which are either successively magnetised and demagnetised or serve as a primary part of a multi-phase linear induction motor when the windings which lie one behind the other are fed by the phases of a multi-phase alternating current source. These two measurements produce a moving magnetic field which serves to transport the workpieces. The air gap, which is important for the force to be transmitted, between the magnetic poles and the workpiece is guaranteed either mechanically by rolling elements (23) or by the adjustable holding force of mutually opposite holding magnets of two mutually symmetrical devices. Provided between the poles (19) of the magnets or around the poles are sensor means (22) in the form of induction coils or semiconductor chips, in order to determine the exact position of a workpiece along the conveying section or the relative position between workpiece and one of the holding magnets. The change in the physical properties of the sensor means (22) appearing when the ferromagnetic workpieces enter the magnetic field serve as signals for control purposes, to deposit the workpiece at a specific point of the conveying section or to activate, deactivate or reverse the poles of the exciting windings (21) for the transport and holding of the workpieces.

Patent ES-8501897-A1 (ES)
Title: Generation of a set point for process control.
IPC: G05B15/02
Filed: 1983-07-15
Abstract: In a process in which a first process variable is manipulated so as to maintain a second process variable substantially equal to a desired value for the second process variable, a set point for the first process variable is generated based on the difference between the actual value of the second process variable and the set point for the second process variable. The magnitude of the set point is determined by the probability that the second process variable may reach an undesirable value and thus control using the set point takes into the consideration the fact that large control actions may be required under some circumstances and minimal control actions may be required under other circumstances in a process.
