  • Patent number: 4139456
    Abstract: Improved process for the oxidation of the Fe.sup.2+ in waste water is disclosed. The process is especially advantageous when applied to low pH acidic waste waters containing substantial amount of the Fe.sup.2+ and is carried out by making use of acid-proof, porous material as a bed-material for iron bacteria to inhabit. The bed-material is suspended in the waste water to be treated and is used repeatedly in a closed circuit.

  • Patent number: 4139867
    Abstract: In order to provide fast- and slow-motion reproduction of video signals a tape is played back at a different velocity, at which the scan traces provide acceptable signals for only a portion of each track at a time, the acceptably picked-up picture lines of these track portions are temporarily stored (others being excluded) and then played back under conditions satisfying television reception standards, in an order determined by an address made up of the line number and a track and field identification provided in response to track and field beginning pulses recorded on the tape. The address can be recorded together with the video signals or can be generated by counting means during the reproduction of the video signals. The tape transport speed is automatically adjusted slightly, if necessary, with respect to the speed setting, to avoid duplicate storage of corresponding lines in successive fields at the expense of omission of other lines.

  • Patent number: 4138604
    Abstract: To provide low contact resistance, long life, and resistance against tarnishing under corrosive, particularly sulfur atmospheres, a substrate carrier has a layer of palladium applied thereto, of a thickness between 0.5 and 5 .mu.m, preferably between 1 and 3 .mu.m, to which a coating of gold is applied which is porous and has a thickness of only between 0.05 .mu.m and 0.1 .mu.m; the porous gold coating forms islands of gold on the palladium which, in use and as the terminal is wiped against a counter element, smears over the palladium, thus effectively covering the palladium, preventing tarnishing, and maintaining low contact resistance throughout the useful life of the terminal element.

  • Patent number: 4136853
    Abstract: A slide valve comprising a housing in which a slide is movably guided between two oppositely facing, flat contact surfaces. Communication between fluid passages in the housing is accomplished by hollow formed passage means on the slide. Seal rings carried in grooves in the slide maintain sealing contact between the slide and the contact surfaces of the housing and seal off the fluid passages relative to each other. Each seal ring consists of a band-shaped contact member and a resilient support member. The support member is arranged to bias the contact member against the contact surface by a force uniformly distributed over the entire length of the contact member.

  • Patent number: 4137060
    Abstract: The jacket of a cored light guide is completely or partially etched away; or, if the light guide is a gradient fiber guide, it is etched to about the light guiding diameter. A lens is then adhered to the end of the fiber, the lens being made of a material having a melting point which is low in relation to the melting point of the core material, to result in a light guide having an essentially semispherical lens at the end; adhesion may be effected by melting on a lens of lower melting point glass, or by making the lens of transparent epoxy, a drop of which can be cured on the light guide to form the lens.

  • Patent number: 4136837
    Abstract: A freely rotatable yarn feeding drum has a plurality of yarn loops wound thereon to form a storage winding. To both drive the drum and axially sheave the yarn forming the storage windings along the length of the drum, a drive wheel, or drive belt is engaged with the circumference of the drum in the region of the storage windings. The drive means thereby directly engages the yarn and the drum and, preferably, the axis of rotation of the drum is so set that it forms an acute angle with the axis of rotation of the drive means to provide an axial frictional component between the drive means, typically a drive belt, and the windings on the drum so that the windings are fed axially.
