Title: Spark gap devices
IPC: H01T21/00
Filed: 1969-04-01
Abstract: Spark gaps (see Division H1) are made by disposing spaced conductive parts between two strips of insulating material which includes a plastics material, disposing said strips and said conductive parts between a pair of rigid pressure members, and moving said pressure members together to press said conductive parts into said strips and to form an insulating member having said conductive parts locked in spaced relation therein.

Patent ES-429159-A1 (ES)
Title: Continuous duplicating sheets
IPC: B41M5/03
Filed: 1974-08-10
Abstract: A dry duplicating method comprising the steps of pressure-imaging a continuous master web with images capable of exuding liquid ink under the effects of contact pressure such as roller pressure and collecting the imaged master web on a roll for duplicating use. The master web is such that at least one surface is receptive to the pressure-applied images but neither surface is capable of absorbing the liquid ink to any substantial degree. The imaged web is duplicated by continuously bringing it into surface contact with an ink-absorbent copy web while pressure is applied to exude the liquid ink from the master images onto the copy web to form a duplicate copy, after which the web is continuously rolled up on another roller for reuse.

Title: Vibration transmission mechanism for a phonograph
IPC: G11B3/00
Filed: 1977-06-08
Abstract: A phonograph of the type wherein a plastics-made tone arm having an upstanding stylus mounted thereon is pivoted eccentrically on a turntable or rotor, under which a speaker is mounted concentrically for simultaneous rotation therewith relative to a record immovably supported above the turntable. Also mounted on the turntable is a metal-made vibration transmitter rod which is substantially pivotally supported at one end and which rests, at a point intermediate both ends thereof, on the armature of the speaker partly exposed through an aperture in the turntable. The tone arm has its free end resting on the vibration transmitter rod for sliding movement, during playback, from the other end of the rod toward its point of contact with the speaker armature. In order to preclude unnecessary changes in the volume of sound generated by the speaker during playback, the distance between the stylus and the variable point of contact of the tone arm with the vibration transmitter rod is made to decrease, with the progress of playback, in as exact proportion as feasible to the distance between the mentioned variable point and the fixed point of contact of the rod with the speaker armature.
