A chassis mountable coaxial cable connector assembly having an isolated ground. A connector pin is attached to the center wire of the coaxial cable with insulation surrounding the connector pin to prevent unwanted signal attenuation to a housing of the connector assembly. The housing is connected to the shielding braid of the coaxial cable with the shielding braid and housing forming a floating type ground. The cable connector assembly includes a unitary constructed flanged cylinder with a threa...

A digital-to-analog converter employing a pair of operational amplifiers connected in a balanced differential configuration to supply an analog output to a two-terminal load. The data and power inputs are isolated from the converter by isolation couplers. Each bit of binary data is sensed at the summing junction of each amplifier by means of a pair of balanced resistors which are switched in accordance with the binary signal. Each set of balanced resistors so sensed is in parallel with the other...

A floating differential input amplifier is connected through a first field-effect transistor gate to an input winding of a signal transformer. An oscillator is connected to a primary winding of a power isolation transformer which transformer has one secondary winding connected to a rectifier circuit which in turn is connected to supply bias power to the differential amplifier. Another secondary winding of the power isolation transformer is connected to operate the first field-effect transistor g...

An ohmically isolated input circuit accepts a three pin connector of a cable from a signal source output for virtually all three pin connector standards, and will output a signal of the same voltage gain regardless of which of the three pin connector standards are used. The input circuit includes two magnetically isolated, serially connected transformers and three input terminals connected to the transformer's serially connected primary windings so that the input signal to any two of the three t...

A protein PP.sub.18 is isolated having the following characteristics: (a) an electrophoretic mobility in the region of that of .beta..sub.1 -globulins; (b) an isoelectric point between 5.6 and 6.2; (c) a sedimentation coefficient s.sub.20,w of 5.0.+-.0.2 S; (d) a molecular weight determined in an ultracentrifuge of 82,300.+-.5,600; (e) a carbohydrate fraction of 2.3.+-.1.3 g/100 g (mannose 0.15.+-.0.1, xylose 0.5.+-.0.5, galactose 0.5.+-.0.2, glucose 0.2.+-.0.1, N-acetylglucosamine 0.7.+-.0.2, a...

In a harvesting and threshing machine utilizing at least one cooperative cylinder and rotatable rotor to achieve axial flow threshing and separation of grain bearing crop material there is provided an improved grain collection means underlying the auxiliary separation and discharge means and overlying at least a portion of the primary cleaning and separating means movably mounted to the frame of the machine in such a manner that air flow generated by the cleaning fan is not disturbed by the rota...

An isolated step mounted on an isolated cab of a tractor with stabilizer means isolating the step from the vehicle chassis and dampening vibrations primarily through shear stress of an elastomer.

A fuel tank resiliently mounted on a vehicle chassis to reduce vibrations of the tank and the noise level at the operator station on the vehicle. The mounting structure for the tank includes brackets connected both to the tank and chassis each providing horizontal and vertical flanges. Resilient isolators are mounted between the horizontal flanges to support the weight of the tank, and resilient isolators are mounted between the vertical flanges to dampen transverse vibrations of the tank.

An isolated signal conditioning circuit is provided whereby control or measurement circuitry is isolated from a load, such as a control instrument, through the use of an optically coupled isolation amplifier. The control or measurement signal is conditioned by the signal conditioning circuit so as to provide a signal to a load, such as a control instrument, which is compatible with the input requirements of the load.

A trigger pulse generation system capable of delivering a multiplicity of isolated 100 kV trigger pulses with picosecond simultaneity.
