  • Patent number: 5024575
    Abstract: A product gripper mechanism, particularly for gripping a plurality of products in a product group, such as bakery products, for transfer to and loading into a shipping basket or tray. The gripper is constructed of a material, such as rigid PVC tubing, which is easily obtainable, lightweight and of substantial strength. The gripper frame includes spaced-apart lateral supports, which carry a plurality of adjustably positionable cross members carrying suction devices. The suction devices are adjustably positionable on the cross members, and may easily be added to or removed from the cross members. The assembly of the tubing elements is such as to accommodate rapid disassembly and reassembly, in order to reconfigure the gripper for different product types. The gripper has pivoting end flaps of L-shaped configuration provided with thin, flexible, inwardly projecting bottom plates.

  • Patent number: 4916438
    Abstract: Methods and circuits are provided for monitoring a battery with the monitored battery electrically connected in an operating system. A dynamic impedance characteristic of the monitored battery is identified and compared with a predefined value. An alarm signal is generated responsive to the compared values to predict a degraded battery capacity. A leakage current value through the monitored battery is detected. An alarm signal is generated responsive to the detected leakage current value to predict a short life expectancy for the monitored battery. Visual and audible alarms are generated responsive to either of the generated alarm signals after the monitored battery has been fully charged. An alarm signal is immediately generated responsive to a detected charging current value above a predetermined value.

  • Patent number: 4653953
    Abstract: A sucker rod construction including a connector member being formed to define a rod receptacle having a closed axially inner end and an open axially outer end. The rod receptacle has a plurality of axially spaced, tapered annular surfaces. The end of a cylindrical fiberglass rod is received within said rod receptacle through the outer end and cooperates therewith to define an annular chamber between the outer surface of the end of the rod and the tapered annular surfaces. A bonding material is positioned in the annular chamber and bonds the outer surface of the end of the rod and the tapered annular surfaces. Each of the annular surfaces has an angle of taper with respect to the outer surface of the fiberglass rod, and each angle of taper is progressively less toward the open end by at least one and one-half degrees.

  • Patent number: 4514836
    Abstract: An improved brush contact for a phonograph tone arm dynamic stabilizer. The contact includes bristles on a base, with free ends fanned in an arc. A portion of the bristles contact a record surface. Lateral movement of the tone arm across the record pivots the bristles and base, bringing new bristles into contact with the record surface.

  • Patent number: 4194590
    Abstract: A loudspeaker horn, which is divided into three segments, is provided with a valve for projecting sound either through the central segment or through all of the segments, said valve being adjustable from the front of the loudspeaker by a knob which has markings thereon to indicate the position of the valve and which is provided with means for retaining it in the position set by the knob.

  • Patent number: 4076427
    Abstract: A writing instrument such as a pen having a nib and a shaft for hand-held use. The shaft is formed with three elongated concave indentations in a generally equilateral triangular configuration with rounded vertices and at least one concave side as seen in cross section in the region normally grasped which form sockets to receive the thumb, index finger and middle finger respectively so as to provide a firm, comfortable and relaxed grasp ensuring complete control of the instrument and virtually eliminating writing tension. The nib is adjustable positionable relative to the shaft axis to provide a nib edge alignment at an angle to the pen's horizontal axis as defined by the three concave indentations, thus ensuring an optimum angle of contact between the nib and a writing surface, regardless of whether the pen is used right or left-handed, for producing attractive pleasing writing.

  • Patent number: 3989905
    Abstract: The disclosure describes improved apparatus for adjusting a unidirectional microphone in order to reduce the electrical output due to mechanical shocks applied to the microphone casing. The microphone includes a diaphragm supported by a housing which is resiliently mounted on the casing. The adjustment apparatus includes a mounting diaphragm positioned between the outer casing and the housing, and an enclosed chamber provided with an air leak which can alter the compliance and resistance of the mounting diaphragm in a controlled manner. A method of balancing the size or value of the elements of the microphone to provide pneumatic shock cancellation is also described.
