Title: Workpiece guide for sewing machines
IPC: D05B35/02
Filed: 1980-08-29
Abstract: A workpiece guide for separately guiding, aligning and removing the curled edges of superposed layers of fabric to be joined by seaming in a sewing machine.

Patent ES-8304652-A1 (ES)
Title: Supply apparatus for mobile gas heaters.
IPC: F24H3/02
Filed: 1982-04-23
Abstract: A catalytic gas burner, as used e.g. in a mobile space heater, comprises a valve housing divided by at least two poppet valves into three or more cascaded chambers. One chamber communicates with a gas inlet and is normally closed by a first poppet valve which can be opened by a push rod and held open by an electromagnet, the latter being energized under the control of a thermocouple as long as an adjoining ancillary nozzle emits a monitoring flame. This nozzle communicates with another chamber to which gas is admitted in the open state of the first poppet valve and which also feeds the main nozzle head of the burner through a supply conduit including a manually and/or thermally controlled flow regulator. A second poppet valve, fixed to the push rod, is open as long as that rod is depressed against a spring force to give access to a further chamber from which supplemental gas is conveyed through another conduit to the nozzle head during a start-up phase while an igniter is being actuated. As long as the first poppet valve is open, gas passes through a throttled branch of the supply conduit to the nozzle head by way of the flow regulator which also has a passage controlled by a piston for letting additional gas from another branch of that conduit enter the nozzle head at a variable rate until the desired temperature has been reached.

Title: Process for producing coincidently embossed decorative sheets.
IPC: B44C3/04
Filed: 1982-05-07
Abstract: First, a decorative sheet is produced by forming in sequence on a base paper such as titanium paper an ordinary printed layer and a heat-foamable printed layer, respectively with desired patterns. The decorative sheet is then impregnated with a thermosetting resin liquid and dried. The dried impregnated decorative sheet is superposed on a substrate such as a core sheet, and the resulting laminated structure is sandwiched between a pair of heating plates and heated and pressed whereby a thermoset integral structure with the pattern of the foamable printed layer foamed is produced. The entire surface of the integral structure is coated with a solvent to swell the foamed pattern layer and then rubbed to remove the swollen foamed pattern layer and form concavities thereat. The resulting thermoset resin decorative sheet or plate is provided with deep distinct concavities coincident with the pattern of the heat-foamable printed layer as well as a good surface luster.

Patent ES-8307374-A1 (ES)
Title: Method and apparatus for the detection of anomalies in electrically conducting rotating members.
IPC: G01N27/90
Filed: 1982-08-13
Abstract: A detector operable to detect cracks in a rotating member generates an alternating eddy current in the rotating member with an external coil surrounding the rotating member.

The frequency of the excitation current is very much lower than the frequency of rotation of the rotating member and a plurality of samples are taken for each degree location. The output signal of the pick-up coil is comprised of both the crack indicative component and a residual or induced magnetism component. The signal is processed so as to extract the desired crack indicative component.

Title: Fet Memory with refresh.
IPC: G11C11/402
Filed: 1982-10-28
Abstract: Depletion-mode FET (13a of 8) joins to enhancement-mode FET (13b of 8) to store charge capacitively as a memory cell. That enhancement-mode FET (13b of 8) is connected to an FET capacitor (19). When the memory stores a high charge, a refresh clock pulse on a line (21), passes the capacitor (19), turns off enhancement-mode part of joined FETs (8), and is effective to gate refresh switch (25) on. When the memory stores ground, the capacitor (19) is not activated and does not pass the refresh pulses. The memory requires very low power for refresh, and is compact and practical for use in large arrays.
