Title: A method for Regulating Development of Crimp in Conjugate Filaments
IPC: D01D5/30
Filed: 1968-06-15
Abstract: The development of crimps in composite filaments having latent crimpability and obtained by simultaneously melt-spinning at least two different thermoplastic synthetic organic to form composite filaments of the sideby-side or of the eccentric sheath-core type and drawing the composite filaments thereby formed is regulated by subjecting the filaments to a preliminary heating step in a primary heating zone at a suitable temperature and under a restrained condition such that the filaments do not develop crimps. The latent crimpability of the filaments is thereby reduced. The filaments are then further heated in a secondary heating zone in a tensionless condition, whereby they develop crimps to the desired degree. The temperature in the primary heating zone is selected according to the desired number of crimps per 25 mm. length of each of the filaments after the treatment in the secondary heating zone. The primary and secondary zones may have the same heating systems and the temperature in the primary zone may be the same as or lower than that in the secondary zone. The primary zone may have a dry heating system and the secondary zone may have a wet heating system of hot water or steam and the temperature in the primary zone may be up to 90 C. higher than that in the secondary zone. Both zones may have hot water heating systems. The primary zone may be a metal tube heating system and the secondary zone may be a jet crimper. The heating medium in both the said systems may be steam. When both the zones have hot water heating systems, the temperature in the primary zone may be 20 to 100 C. and that in the secondary zone about 100 C. When the primary zone is a metal tube heating system or a heated roller system and the secondary zone a jet crimper system or a cylindrical means for developing crimps, the temperature in the primary zone may be 20 to 180 C. and in the secondary zone about 180 C. Alternatively, the temperature in the primary zone may be 130 to 190 C. and that in the secondary zone about 190 C. The components of the composite filaments may be a homopolyamide and a copolyamide, a polyester and a polyester-ether, a polyamide and a polyester or polyolefins having different shrinkabilities or different intrinsic viscosities. One component may be nylon-6 and the other a copolymer of #-caprolactam and hexamethylene diammonium isophthalate or hexamethylene diammonium terephthalate. One component may be polyethylene terephthalate and the other polyethylene paraoxybenzoate or a copolymer of polyethylene terephthalate with polyethylene isophthalate or with polyethylene paraoxybenzoate. One component may be nylon-6 and the other polyethylene terephthalate.

Patent ES-361706-A1 (ES)
Title: Defrosting control circuit for electric refrigerator
IPC: G05D23/24
Filed: 1968-12-20
Abstract: A defrosting control circuit for an electric refrigerator has a first transistor 1 for triggering a solid state switching element e.g. a thyristor 3, and a second transistor 2 for resetting the circuit on completion of a defrosting operation, the second transistor base being supplied with a determined potential while the element is conductive and a temperature detecting element e.g. a thermistor 10, sensitive to the temperature inside the freezer, arranged to supply a base bias to one of the transistors during the defrosting operation. Momentary closure of a pair of manually or time-switch operated contacts 8 renders transistors 1, 2 conductive which fires a thyristor 3 energizing a defrosting heater 6, the voltage across which maintains the transistors conductive on release of the switch 8. A rise of temperature of the freezer decreases the resistance of thermistor 10 which at a given point resets the circuit into a non-conductive condition. In another arrangement. Fig. 2 (not shown), the contacts 8 and thermistor are connected to the base of transistor 2. The heater 6 may be replaced by a valve through which a hot gas may be supplied to the freezer. The arrangement is stated to completely defrost a freezer irrespective of the amount of frost accumulated.

Title: Planar epitaxial process for making linear integrated circuits
IPC: H01L27/082
Filed: 1972-06-30
Abstract: An integrated circuit, including several juxtaposed units such as a low-ohmic resistance, an NPN power transistor and a PNP lateral transistor, is produced by forming a corresponding number of N+ strata side by side on a substrate of P-type silicon, epitaxially growing an N-type layer on that substrate to imbed the N+ strata therebetween, isolating the several units from one another by diffusing P-type impurities in intervening regions to divide the N-type layer into sections separated by P-type zones unitary with the substrate, and doping the resulting N-layer sections at selected areas with impurities of either conductivity type through windows formed in an overlying film of silicon oxide. The introduction of P-type impurities is preceded in each case by a more concentrated doping of all or part of the respective area with P+ impurities, followed by a simultaneous diffusion of the P and P+ impurities to a predetermined depth within the respective N-layer sections to form P-type enclaves therein to which metallic terminals are subsequently applied.

Title: Transistorized control circuit for magneto motor ignition systems
IPC: F02B1/04
Filed: 1973-08-27
Abstract: During the negative half cycle of the magneto output voltage, a capacitor in series with a diode is charged to a voltage limited by a Zener diode of a negative limiting circuit. During the next positive half cycle the sum of the magneto voltage and the capacitor voltage are applied over a current limiting resistor to the base of a power transistor in the primary circuit, holding the latter turned on until a timing pulse applied to a control transistor short circuits the base-emitter path of the power transistor, switching off the latter and permitting the capacitor to discharge. The interruption of the primary current produces a spark in the secondary circuit, the armature of the magneto being wound to serve also as an ignition coil.
