Title: Electronic circuits for sewing machines
IPC: G05B19/18
Filed: 1976-04-15
Abstract: A control unit for a sewing machine includes a mechanism for mechanically positioning the stitch-forming members and a pattern memory unit for controlling this mechanism, from which stitch position detemining code words belonging to a specific pattern can be selected by the operator. The code word for determining a stitch position is read from the pattern memory into a shift register. The shift register is shifted in relation to the movement of the main shaft of the sewing machine so that code words for each successive stitch of a pattern are successively made available to the mechanical positioning mechanism. The succession of code words in a pattern can be recirculated in the shift register at the end of a pattern cycle, for repetition of the pattern.

Title: Paper perforator
IPC: B26F1/36
Filed: 1977-09-13
Abstract: The letter perforator has a lower part composed of a base plate (1) which forms the punching die and two edge side parts (11, 11') which are connected to the said plate and on which there are formed tabs (12, 12') which contain the punch guides (13, 13'). The entire lower part is punched from a piece of sheet metal. The web forming the punching die is formed by a part (2) which is cut away from the base plate (1) on three sides of a rectangle, is initially bent approximately vertically upwards and is then bent horizontally backwards. By means of lateral tabs (9, 9') which rest on edges (10, 10') of the side parts (11, 11') which are bent upwards at right angles, the punch pressure is transferred to the lateral parts (11, 11') which contain the bearings (16, 16') of the pressure plate.

Patent ES-462489-A1 (ES)
Title: Directional pulse oscillator
IPC: H03K3/0231
Filed: 1977-09-20
Abstract: In the initialising-pulse transmitter, a voltage U1 to be monitored is supplied to a limit-value detector (11) at the output of which a signal U15 is present which changes its defined state with a transgression of an adjustable limit value Ug. This signal is used for setting circuit modules of closed- and open-loop control technology to an initial state when the supply voltage is switched on or is restored after a voltage dip. It is the object of the invention to develop an initialising-pulse transmitter in such a manner that it can be fed with the voltage to be monitored and no separate auxiliary voltage is required. For this purpose, the voltage U1 to be monitored is applied to the series circuit of a resistor (3) and two capacitors (4, 5) in a supply section (2), a Z diode (6, 7) being connected in parallel with each capacitor. As a result, a stabilised internal supply voltage is generated which is independent of short-term fluctuations or dips in the voltage to be monitored. In the limit-value detector (11), which exhibits an operational amplifier (14), a signal-delaying filter (17) is provided which ensures that the limit-value detector (11) only receives the information on the voltage to be monitored when the internal supply voltage is sufficiently high. For this purpose, the common-mode input (14a) of the operational amplifier (14) is connected to the tap (12a) of an adjustable voltage divider (12) at which the voltage to be monitored is present, and the push-pull input (14b) is connected to the junction (10) between the two capacitors (4, 5). Furthermore, a series circuit of two diodes (21, 22), the junction of which is connected to the tap (20) of an RC section (18, 19), the resistor (18) of which is connected to the junction (9) between resistor (3) and capacitor (4), is connected between the common-mode input (14a) and the push-pull input (14b) of the operational amplifier (14).

Title: Method for the production of 2,4,6-tri(3,5-ditertiary butyl-4-hydroxybenzyl) mesitylene
IPC: C07C39/16
Filed: 1977-10-11
Abstract: A method for the production of 2,4,6-tri(3,5-ditertiary butyl-4-hydroxybenzyl)mesitylene which resides in treating a mesitylene solution in chloroalkane simultaneously with sulfuric acid used as a catalyst and a solution of 2,6-ditertiary butyl-4-methoxymethylphenol or bis-3,5-ditertiary butyl-4-hydroxybenzyl ether in chloroalkane at a temperature of -20 DEG to +20 DEG C. This results in a reaction mixture consisting of an acid phase and an organic phase including the target product. The phases are separated. The organic phase is subjected to neutralization by the treatment thereof with gaseous ammonia used as an alkaline agent. The precipitate of ammonium sulfate is separated and chloroalkane is removed from the remaining solution. The proposed method makes it possible to obtain the target product with a yield of 88 to 90% and a melting temperature of 239 DEG to 239.5 DEG C. The method prevents the formation of effluents, and the amount of phenol wastes is considerably reduced.

Patent ES-471224-A1 (ES)
Title: Electro-mechanical impact device
IPC: B25C1/06
Filed: 1978-06-28
Abstract: An electro-mechanical impact device, useful for driving nails, staples and other fastening elements. The driving member is driven by frictional engagement between a pair of counter-rotating high speed flywheels. The device has a safety provision whereby it cannot be actuated until the nose of the device is pressed against a work piece. This action also produces a movement of one of the flywheels toward the other. Actuation of the trigger moves the driving member into engagement between the counter-rotating flywheels, and these propel the driving element in a fastener driving direction. The inertia of the movable flywheel aids in efficient engagement of the flywheels with the driving member, and the movable flywheel is provided with a leaf spring permitting it to yield so that the driving member can pass between the flywheels while maintaining frictional engagement between the flywheels and the driving member. The driver is connected to an elastic member, so that when the tool is lifted from the work, the movable flywheel is moved away from the fixed flywheel, and the elastic member then retracts the driving member between the flywheels to a position out of contact therewith. The two flywheels are driven in synchronism by a single electric motor.

Patent ES-475876-A1 (ES)
Title: Hydrophilic polyester fiber and process for making same
IPC: D01F6/62
Filed: 1978-12-11
Abstract: A new and useful hydrophilic polyester fiber and process of making same are disclosed the fiber has a stable pore system exhibiting a moisture pickup (regain) of at least about 2 percent by weight at 40 DEG C. and a relative humidity of 92%. Our experiments indicate that the proportion of moisture regain is attributable to capillary condensation in an amount of at least 25%. The hydrophilic properties are the result of a certain pore system within the fiber which enables capilliary condensation to occur significantly. The invention describes one way to accomplish this, namely by the addition of a predetermined amount of a suitable oxalato-complex to a suitable polyester mass. Most preferably, about 10% by weight K3Al(C2O4)3 is added to the polyester mass. The fibers are produced by extruding a suitable polyester mass containing 1 to 20 percent by weight of a suitable oxalato complex to form a filament, drawing the filament, and hydrosetting the drawn filament at a suitable temperature, generally between about 90 DEG C. and about 170 DEG C., preferably between about 120 DEG C. and about 140 DEG C., under pressure, and in the presence of liquid water. The hydrophilic polyester produced by the novel process has the favorable moisture regain and many of the favorable texture qualities of cotton, together with the quick drying qualities of conventional polyester fiber.
Patent ES-476145-A1 (ES)
Title: Isotopically selective photoionisation
IPC: B01D59/34
Filed: 1978-12-19
Abstract: Apparatus and process for isotopically selective multistep photoionization in which the ionizing step is tuned to produce a specific transition to an excited state above ionization for which the ionization cross-section is substantially greater than for ionization transitions in general. The autoionization transition to an ionized state is made from a highly excited bound state reached in one or two isotopically selective energy jumps from the ground state or other low-lying levels. The isotope shift for the ionization transition is small compared to the bandwidth of the ionization transition and relatively broad band photoionization radiation covering the entire absorption line can be employed. A technique is also shown for identifying the ionization transitions of augmented cross-section.
