Title: Film Production.
IPC: B29C48/03
Filed: 1967-08-14
Abstract: A film of a polymer which is polyethylene, polypropylene, or an oxymethylene polymer and having an elastic recovery from 50% strain of at least 70% at 25 C. is obtained by a process comprising extruding in the form of a film a molten polymer at a melt temperature no higher than 100 C. above the crystalline melting point of the polymer, cooling the extrudate within two inches of the extrusion orifice, and stretching the solidifying extrudate at a high rate of draw-down and at a drawdown ratio of at least 20 : 1 and annealing the resulting stretched film at a temperature of 5 to 100 C. below the crystallinic melting- point of the polymer for a period of at least 5 seconds. The extrudate is cooled by contact with a cooling roll or a cooling air stream. The process may be carried out to produce a planer film or a tubular film by a "blown film technique". Diagrams of suitable apparatus for both variations of the process are included.

Title: Stabilized capactive sawtooth generator
IPC: H03K4/50
Filed: 1970-12-04
Abstract: A semiconductor arrangement for charging and discharging a capacitor. The discharge period is stabilized for variations in temperature and supply voltage by making the charge voltage equal to the discharge voltage applied across the leakage resistor. This is implemented by connecting the leakage resistor to the supply voltage through a plurality of stabilizing transistors, while the capacitor is charged from the supply voltage through switching transistors. The charge period is made much shorter than the discharge period and in one preferred embodiment all components except the leakage resistor and the capacitor are integrated in a semiconductor body. Two transistors in a common emitter configuration driving a third transistor are described to provide the capability for controlling the frequency and phase of the output signal of said arrangement.

Patent ES-423187-A1 (ES)
Title: Free piston engine with antiknock means
IPC: F01B7/04
Filed: 1974-02-13
Abstract: A free piston engine in which knocking of the engine is prevented by changing the return energy available to move the piston in its compression stroke and hence to vary the compression ratio. The apparatus includes a condition responsive means associated with possible knocking of the engine, which controls some controlling means for varying the return energy. Where the free piston engine employs a bounce chamber for controlling the return energy, the controlling means may be effective to change the pressure in this bounce chamber. Where the free piston engine has two power pistons acting alternately on a single assembly, the pressure ratio may be varied by controlling the amount of fuel admitted into one or more of the power cylinders. The apparatus also contemplates means for changing the return energy if a movable member driven by the piston moves too far with respect to an associated stationary member.

Title: Power supplying device for the operation of a gas discharge container
IPC: C21D1/38
Filed: 1974-02-18
Abstract: A power supplying device for the operation of a gas discharge container for the treatment of metallic workpieces. For the provision and the adjustment of the operating voltage the power supplying device comprises a transformer, a thyratron-or thyristor full-wave rectifier located in the secondary circuit and an ignition control device for the ignition of the rectifiers. The power supplying device further comprises a device monitoring the discharge and in response to which the ignition control device further serves as a quick-action switch interrupting the discharge during a number of periods. An inductance is located in the primary circuit having such design that the increase of the operating voltage following every zero passage is retarded. Resulting is an extension of the interruption of discharge occuring at every zero passage of the operating voltage causing minor discharge disturbances on the workpiece surface to decay.

Patent ES-459417-A1 (ES)
Title: Tyre chains
IPC: B60C27/06
Filed: 1977-06-02
Abstract: The tyre chain is composed of chain links (1, 2) which are arranged upright and, respectively, horizontally and form meshes composed in each case of four chain links (1) which are arranged upright and are joined to one another by a chain link (2) which is arranged horizontally. The mesh area bounded by adjacent junction points (4) and the free link-aperture area bounded by the chain link (2) which is arranged horizontally and is elongate, are essentially of the same size. By this means, uniform wear of the tyre is achieved. Due to the elongate design of the chain links (2) forming the junction points (4) a considerable saving in chain links is achieved for a given chain length. The tyre chain is of a low weight, as a result of which small centrifugal forces and only a low degree of inner wear of the tyre chain occur during driving. The elongate chain links (2) rotate with their longitudinal axis in each case in the direction of the main force component, as a result of which a self-tightening effect is achieved.
