Title: Improvements in or relating to Welding
IPC: B23K9/028
Filed: 1967-10-13
Abstract: Two parts 1, 5 are welded together by friction welding an annular ferrule to one of the parts, e.g. 1, to form a spigot thereon and by welding the other part, e.g. 5, to the ferrule by friction welding or non-consumable electrode arc welding (Fig. 2, not shown).

Patent ES-364751-A1 (ES)
Title: Automotive anti-skid control system
IPC: B60T8/58
Filed: 1969-03-13
Abstract: In a road-vehicle anti-skid braking system, wheel deceleration and acceleration signals energize solenoid valves at predetermined levels -g +g 1 + g 2 , to control vacuum-actuated regulating valves in the wheel brake pipe. Regulating valve, Fig. 4.-Comprises a spring- loaded diaphragm 310 with a small leak 311, and driving a piston-rod 320. When solenoid 314 is energized (at - g) to admit atmosphere to one side of the diaphragm it moves to the left with rod 320 allowing ball-valve 322 to close the master-cylinder pipe and increases the volume of space 341 connected to the brake pipe 331 (thereby reducing brake cylinder pressure). At a low level of wheel acceleration +g 1 solenoid 314 is de-energized, and leak 311 allows the spring to return the diaphragm and rod 320 slowing pumping fluid back into the brake pipe. If the wheel accelerates to +g 2 solenoid 350 is energized, connecting both sides of the diaphragm through pipe 351 to allow a rapid return to full braking. Skid control system. Fig. 1.-As shown, the front wheels are controlled separately by regulators 14, 15, and the rear wheels jointly by regulator 13. The speed of the wheels is detected by, e.g., tacho-altemators 30-33, and above a minimum slow speed determined by threshold circuits 51, is fed to counters 45 providing a D.C. signal proportional to speed, which is differentiated at circuit 47 to provide the acceleration signal. The value of the acceleration is determined by comparators such as 55, 56, 57. At value - g comparator 55 triggers circuits, e.g. 64, 70, to open AND gate 82, causing the regulator to reduce brake pressure at value + g 1 comparator 56 inhibits the AND gate so that brake pressure increases slowly and at value +g 2 comparator 57 controls the regulator to rapidly increase brake pressure. Rear wheel control is determined by a differential amplifier "select" circuit 50 which may be arranged to select either the fastest rear wheel or the slowest rear wheel for the control channel. Suitable transistor circuits are illustrated in Figs. 7, 8 (not shown). Parked/locked wheel discriminator.-Since it is desirable to have normal braking at very low speeds a logic circuit 46 is provided comprising an R.C. delay circuit (142), (143), (158), Fig. 6A (not shown), which keeps the control channel open for 0.4 seconds after the wheel signal drops below threshold value. If the wheel is locked, brake release will allow it to speed up in this time and control the normal antiskid cycle, but if the vehicle is slowing to a stop the wheel' signal will remain below threshold, and the antiskid circuits will not be operative.

Title: Process for the production of capacitors
IPC: H01G4/18
Filed: 1969-06-21
Abstract: Capacitors are manufactured by winding a number of parent or master windings one upon another, coating the windings in common with metal on the face sides thereof by a metal spraying process and separating them one from the other. In one instance, the master windings are separated one from the other by the provision of inactive layers which project at the face sides or ends of the windings to prevent contacting of the layers of the windings during metal spraying. In another embodiment the interlayers are dimensioned as wide as the capacitively active layers and the face-side zones of the interlayers are masked during the application of the metallic layers. In yet another embodiment the inactive layers are completely metal coated and separation is provided by sawing or cutting in the zone of the interlayers. In this case, the interlayers remain on the finished partial capacitor as cover layers.

Patent ES-406780-A1 (ES)
Title: Stored charge detection by charge transfer
IPC: G01R29/24
Filed: 1975-03-31
Abstract: The amount of charge stored in a charge storage system can be transferred with negligible loss from the storage system to a charge detector without regard to the size of any distributed capacitance present on the line transferring the charge. This is achieved by charging a detector capacitor and the capacitance of the transfer line, to a reference voltage, allowing the stored charge system and the transfer line capacitance to equalize at a voltage level below the reference voltage, and transferring charge from the detector capacitor to the line capacitance and the charge storage system to return the line and the charge storage system to the reference voltage of charge. The voltage remaining on the detector capacitor is then equal to the original state of charge in the storage system.

Title: Polymers stabilized with polymerizable vinylbenzyltrialkyl ammonium salt surfactant
IPC: C09K23/52
Filed: 1974-10-03
Abstract: An effective amount of a vinylbenzyltrialkylammonium salt, prepared from a vinylbenzyl halide and a tertiary amine, is polymerized with various other monomers to afford stable latex polymers which have the latex stabilizing surfactant incorporated into the polymer backbone. The use of a vinylbenzyltrialkylammonium salt lessens or avoids the usual problems associated with the conventional anionic, nonionic or cationic emulsifiers employed in aqueous polymerizations that is, the latex stabilizing surfactant incorporated into the polymer backbone is the sole emulsifier employed. The copolymers prepared with the quaternary ammonium compounds are useful as sizing agents, as extender/binders for cationic water repellents in addition, the polymers are depositable on pulp without requiring any deposition aids or defoamers.

Title: Apparatus for cleaning inside and outside surfaces of containers
IPC: B08B9/34
Filed: 1975-03-20
Abstract: Apparatus for cleaning open-mouthed cylindrical containers has a plurality of pot assemblies mounted on a turntable rotatable to move each pot assembly past an unloading station for discharge of containers from the pot assemblies and a loading station for insertion of containers into the pot assemblies. Each pot assembly comprises a body co-operating with a lid to define a cavity for reception of a container, the cavity having a shape corresponding approximately to that of the container and having a size such that the container subdivides the cavity into two chambers in which the walls of the cavity are spaced close to the inside and outside surfaces of the container. Cam rollers on each pot assembly co-operate with cam tracks, upon rotation of the turntable, to open the lid immediately prior to passage past the unloading station and to close the lid immediately after passage past the loading station. During passage between the loading and unloading stations cleaning liquid is circulated through the chambers, the liquid flowing along the inside and outside surface of the container to clean the surfaces. The liquid flows at high speed due to the small volume of the chambers. Rinsing water is then circulated through the chambers, and finally drying fluid to dry the container before discharge at the unloading station.

Title: Coupler for premodulation stage in carrier frequency channel converter - has outside-band signals frequency located on channel filter curve
IPC: H04J1/04
Filed: 1975-09-25
Abstract: The coupling circuit, for the pre-modulation stage in a carrier frequency channel converter, uses electromagnetic channel and signal filters with transformers tuned to the channel filter passband centre and connected before and after the filter. The transformers are designed so that the channel filter input and output impedances have a maximum value above and below the passband. A signal outside the band is obtained from the signal filter and introduced into the transmission path. To compensate for signal level fluctuations due to temperature variations, the upper maximum of the output and the input impedances of the channel filter is located so that the frequency of the coupled outside-band signal lies on the higher frequency, falling slope of the impedance maximum.
