A balancing loop including a housing inside of which is disposed a first conductor part having a first sublength and a second sublength, with the first sublength constructed as a coaxial line passing through the housing and having its inner conductor terminated inside the housing and connected to a second conductor part, and the second sublength extending from the termination of the inner conductor to the second conductor part to an output line. The second conductor part also has the first and s...

A balancing mechanism having a vertical robot arm and horizontal robot arm pivotally mounted to the vertical arm and for each robot arm a link mechanism having a lever as well as a spring connected to the robot arm to be balanced through the link mechanism so that the spring expands and contracts in accordance with changes in the quantity of movement which occurs as the robot arm rotates or travels so as to balance the robot arm.

This invention is a simulated bird in hovering flight, including a bird figurine having spread wings and a tail forming three spaced-apart counterweights for a beak of the figurine, which is rested upon an upper end of an upright post.

A rotor portion of a gas turbine engine comprises two parts which are clamped together by an annular array of bolts. Each bolt head carries a set screw which retains a balancing weight in a position on the bolt head. The balancing weights are so distributed between the bolts as to balance the rotor portion about its axis of rotation.

A balancing ring automatically balances an unbalanced rotating object without adding or removing weight to the object. The balancing ring comprises an airtight annular chamber that is partially filled with a high viscosity balancing material. The annular chamber is preferably created as an enclosed chamber by casting the object using the lost foam process. Alternately, the annular chamber may be a groove formed in the object and sealed with a cover, or it may comprise a tube formed into a circul...

A tire gel balancing composition having a Storage modulus of between 3000 and 15000 Pa and the Specific Gravity less than 1000 kg/m.sup.3 in the temperature range between -20.degree. and +90.degree. C., preferably its Storage modulus is about 9000 Pa, is capable of balancing tires by being able to flow under the vibrations caused by imbalance in a wheel assembly. The composition preferably comprises a mixture of: 1) paraffinic oils, polybutene oils, polyol esters, including castor oil, or polyol...

A balancing apparatus which is capable of compensating for an eccentricity generated even when a rotating member is rotated at a velocity that is lower than a critical velocity thereof. Preferably, the balancing apparatus is disposed, in relation with the rotating member, at a position spaced apart from a rotation center of the rotating member by a predetermined distance. The balancing apparatus includes a plurality of balls for compensating for an eccentricity, a hardening agent for fixing the ...

A balancing jacket for scuba divers is in the form of a sleeve-less waist-length jacket made from strong, heavy materials worn over a diving suit made from neoprene. Pads made from a soft plastics material are placed in the armholes and in the neck area of the jacket. The jacket further includes a soft back covered with an elastomeric material with a high coefficient of friction on neoprene.

A balancing radiometer for measuring the intensity of incident electromagnetic radiation comprises: a pair of identical sensors, each including a thermally conductive substrate, at least one surface of the substrate being comprised of an electrically insulating material, and means disposed on the one surface for resisting the flow of electric current and absorbing incident radiation; means for shielding one of the two sensors from the radiation source, the other sensor being unshielded; means di...

A rotor to be balanced has an annular cavity containing two balls free to roll around the cavity. An initially inert thermo-setting adhesive is coated around the cavity. The rotor is rotated to a speed just above its first resonant frequency of vibration and the balls take up balancing positions in the cavity counter balancing the out of balance of the shaft. The adhesive is activated by a temporarily placed external heat source to permanently lock the balls in the balancing position so that the...
