Abstract: A linear rail system having an apparatus for adjusting the preload on the individual rollers of the slider body which provides a linear rail of the type having upper and lower parallel raceways through which a slider body having a number of rollers attached thereto is adapted to axially translate. The rollers are assured contact with the upper and lower raceways while also providing the ability to absorb shocks placed on the slider body.

Abstract: A linear rail system for adjusting the preload no the individual rollers of the slider body provides a linear rail of the type having upper and lower parallel raceways through which a slider body having a number of rollers attached thereto is adapted to axially translate. The rollers are assured contact with the upper and lower raceways while also providing the ability to absorb shocks placed on the slider body. At least one of the rollers is mechanically biased against one of the raceways while at least one other roller is adjustable and fixable in position using an adjustment block.

Abstract: A rubber hose is coupled to a metal tube by a connector having an inner tubular component which is fixed within an internally threaded sleeve and which telescopes into the end portion of the hose. An externally threaded sleeve is rotatable on the end portion of the hose and, when tightened into the internally threaded sleeve, engages a nut on the end portion of the hose to force the tube axially onto a frustoconical portion of the tubular component and establish a seal around the hose. The thread of the nut is of opposite hand from the threads of the sleeves to prevent the nut from running off of the hose if the nut is turned during tightening of the externally threaded sleeve.

Abstract: A chain merchandising apparatus includes a frame, a cabinet secured to the frame, and a chain support mounted to the frame and located within the cabinet for supporting a plurality of chain containers. A chain cutter is moveably fixed to the apparatus so as to be facilely and safely selectively adjustable vertically and horizontally in relation thereto for permitting a user to position the chain cutter substantially adjacent to a preselected chain container supported on the chain support.

Abstract: A low-friction bearing material includes a matrix formed by a wire mesh screen which is fused to a metal backing sheet. Polytetrafluoroethylene or other polymeric resin fills the interstices within the screen and between the screen and the backing sheet and locks itself rigidly to the screen and the backing sheet in order to impart high strength to the bearing material.

Abstract: A linear motion guide assembly is disclosed which employs an extruded U-shaped aluminum channel with inserted hardened steel races. A linear slider having recirculating roller element bearings which is slidably mounted upon the extruded track. The load bearing races of the recirculating bearings are opposed to in a spaced parallel relation to the insertable bearing races of the track. The track has linearly extending structures substantially parallel to the track races the structure being of substantially decreased stiffness so forming elastic hinges which supply an elastic pre-load between the track and the linear slider and wherein the lower modulus of the housing and the hinged structure allow significant deflection of the housing without excessively pre-loading the bearings.

Abstract: A shaft is supported to slide in a linear bearing which, in turn, is supported within a bore in a pillow block housing. To enable the bearing to self-align with a bearing in a paired pillow block housing, the bore of the housing is longitudinally crowned and permits the bearing to rock universally within a limited range while still maintaining rigidity and precise centerline accuracy.

Abstract: When two substantially identical signals contaminated by uncorrelated noise are received over two channels, combining of the contaminated signals in a linear manner results in a maximum signal-to-noise ratio improvement of 3 dB. The present disclosure relates to combining such contaminated signals through a process whose parameters vary as short time functions of the signal and noise powers in each channel. This processing produces a signal-to-noise ratio improvement which is greater than that achievable through linear processing.

Abstract: A relatively high sensitivity and high speed current detector consists of essentially a common base differential amplifier consistng of two junction transistors, each having separate emitter and collector resistors, and a constant current source connected to the collector resistors. Separate input terminals connected to the emitters allow complementary information current signals or an information current signal and a reference current signal to be applied to the emitter terminals. The output signal and the complement thereof appear at their respective collectors.

Abstract: An improved TTL to MOS voltage level shifter circuit utilizes a totem pole output stage consisting of a pull-up junction transistor and a pull-down saturation junction transistor, an intermediate stage consisting essentially of a saturation junction transistor, an input stage consisting essentially of a diode and a saturation junction transistor, and current spike inhibit circuitry which consists essentially of a saturation junction transistor connected between the input stage and the base of the pull-down transistor. The current spike inhibit transistor, which turns on with the pull-down transistor, has a greater turnoff time than the pull-down transistor and consequently provides a relativley low impedance discharge path connected to the base of the pull-down transistor which allows the pull-down transistor to turn off before the pull-up transistor turns on. This helps insure against output current spikes that occur if the pull-up and pull-down transistors conduct simultaneously.
