摘要:
A device for use with coaxial cable to attenuate sheath currents associated therewith. The device is adapted to be coupled to incoming and outgoing coaxial cables and includes a ferrite core configured as a first hollow cylinder mounted coaxially within a housing configured as a second hollow cylinder. A conductor within the housing has opposite ends positioned for electrical contact with the incoming and outgoing coaxial cables and an intermediate portion passing through the ferrite core longitudinally at least twice, being passed back over the outside surface of the core between passes therethrough. The elements are so dimensioned that the outside diameter of the housing is less than one inch, thereby allowing side-by-side mounting of a plurality of the devices on industry-standard, multi-port taps which have center-to-center spacings of one inch.

摘要:
An assembly for housing electronic components for use in a CATV system. The assembly includes a hollow body member having a central axis and opposite ends, at least one header adjoining one end of the body member in coaxial relation. The body member includes a notch in one end and the header includes a tab configured to extend into the notch to rotationally lock the body member to the header. The assembly may also include a plurality of hollow body members and a pair of headers each having a central axis. The body members and headers are positioned in an axially aligned array with the headers at opposite ends. The assembly includes cooperative structure rotationally locking each of the body members and headers to the adjacent body member and header. The assembly may further include a sleeve covering at least portions of the body member and headers.

A device providing an enclosure for electronic components of an RF filter, trap, or the like for use in a CATV system. The device includes a hollow, cylindrical body portion with male and female headers at opposite ends with mutually engaged portions of the body and headers serving to rotationally lock the body and headers to one another. The mutually engaged portions comprise a pair of notches in each end of the body member and a pair of tabs on each of the headers which extend into the corresponding notches, the tabs and notches having substantially equal widths to prevent rotation of the headers relative to the body upon application of a torque, such as occurs when the devices are installed and threaded to an adjoining connector. In addition to the single body version, the invention is disclosed in a six-pole version having three body members arranged in successive, coaxial relation and rotationally locked to the headers at each end and to adjoining body members. In both versions, the body member(s) and header(s) are maintained in longitudinally assembled relation without the conventional induction soldering operation. In the first embodiment the body and headers are enclosed in a closely fitting sleeve having opposite ends which are formed over the peripheries of the headers. In the second embodiment, longitudinally adjoining members are joined by interference fit with a locking ring and groove to lock the inner body to the header.

A supercharger system for an internal combustion model engine is driven by the associated engine and includes a drive belt, a belt driven pulley and a mounting bracket. The pulley drives a shaft, which is connected to the turbo impeller. The impeller is driven at multiple speeds within a volute. The turbo impeller is recessed into an internal housing to provide smooth air flow from the impeller into the volute. The mounting bracket provides flexibility in mounting to various internal combustion model engines. A portion of the supercharger output pressure can be diverted through a hose containing a check valve and used to create positive pressure in a pressurized fuel cell, resulting in consistent and even flow of fuel into the engine's combustion chamber.
摘要:
A pitch changing apparatus, providing bi-stable operation within a tremolo system which produces two distinct pitches for selected strings. The apparatus includes a shifting element 56, which is engagable to introduce or remove a pre-determined thickness within a tremolo system, creating string tensions relative to chosen, distinct pitches. An established ratio of total string tension and opposing spring counter-tension acting upon a tremolo is maintained by a tension correcting mechanism 73. The tension correcting mechanism is manually rotated to adjustable stop positions of required spring counter-tension, thereby keeping all strings in tune under conditions of changed total string tension.

A process for the production of ethanol from biomass is disclosed. The process relates to the pretreatment of corncob biomass and includes the steps of exposing corncob to steam in a reaction vessel at an elevated temperature and reaction pressure for a preselected exposure time. Volatile compounds are continuously vented during pretreatment. The reaction pressure is released for explosive decomposition of the corncob biomass into fibrous solids and condensate. The exposure is preferably carried out at a temperature of 190-210° C. and a pressure of 190 psig to 275 psig and an exposure time of 3 to 10 minutes.

A direct torque flow constant velocity joint connection interface includes a drive unit, a direct torque flow constant velocity joint connector and a sealant. The drive unit includes a shaft having a second interface surface. The direct torque flow constant velocity joint connector includes a unitary inner joint part having a first interface surface, where the first interface surface is connected to the second interface surface of the drive unit. The sealant provides filling between the first and second interface surfaces. Also provided is a direct torque flow constant velocity joint connector having sealant on an interface portion of an inner joint part and a method thereof.
