  • Device for collecting manganese nodules on the ocean floor
    Patent number: 4652055
    Abstract: A device for collecting manganese nodules or the like from the ocean floor having a frame that is drawn across the ocean floor, a cylinder rotating around a horizontal axis which has on its circumference brushes for picking up manganese nodules in the circumferential direction. A screen surrounds the rear half of the cylinder. Hook-like rods mounted on the screen terminate in prongs pointing in the traction direction for digging out manganese nodules. The bristles can be made of bronze and are in the form of ribs running in the axial direction of the cylinder. Because of the brushes, the jamming of the nodules is prevented and at the same time a cleaning action is performed on the nodules.

  • Eccentricity measuring apparatus
    Patent number: 4651438
    Abstract: In an apparatus for measuring the eccentricity of an eccentric bearing face having an axis of rotation, a rotary motion and a perimeter, the apparatus comprises a length measurement gauge, mounting means for mounting the length measurement gauge, means for guiding the movement of the length measurement gauge, in which the guiding means comprises a follower and two bearing tips, and means for applying the bearing tips to the eccentric bearing face. The mounting means for mounting the length measurement gauge functions to (a) maintain the length measurement gauge in the radical direction during rotary motion, and (b) enable the length measurement gauge to move perpendicularly to the axis of rotation. The guiding means functions to guide the movement of the length measurement gauge in the direction of the rotary motion of the eccentric bearing face.

  • Speed control for an electric golf car
    Patent number: 4648473
    Abstract: A speed control for an electric golf car providing sequential changing between a plurality of speeds such that the golf car must accelerate through fixed speeds for predetermined times prior to reaching a full speed. A foot pedal actuable by the operator controls a plurality of magnetic reed switches. The reed switches in turn control a timing circuit for generating a plurality of motor drive signals in succession at predetermined times. The motor drive signals actuate relay coils for applying power to the golf car motor.

  • Pneumatic pipe inspection device
    Patent number: 4646787
    Abstract: A pipe worm comprises radially inflatable toroids spaced along an axially inflatable tubular body. The worm inches through piping through sequential inflation and deflation of the toroids and tubular body. The worm includes a fluid supply source, pipe maintenance instrumentation and automatic, semiautomatic or manual controls which are remote, on-board or trailered, as desired. The worm is inexpensive, reliable, capable of turning 90 degree corners, and further uniquely advantageous.

  • Device for connecting electric conductors
    Patent number: 4646957
    Abstract: An ultrasonic welding apparatus for electrical conductors comprising strands of wire comprising a sonotrode for generating ultrasonic vibrations and a cooperating anvil having movable side walls to compress the wire strands against the head of the sonotrode. The anvil has two moving parts, one moving back and forth parallel to the fixed sonotrode face, and the other moving up and down normal to the fixed face. The moving parts carry the side walls of the anvil and with the fixed face provide an adjustable space for wires of various sizes, the space having a rectangular cross section. The gap between the moving anvil parts and the adjacent fixed face of the sonotrode are accurately controlled.

  • Electrical film resistor
    Patent number: 4647899
    Abstract: An electrical film resistor. The film resistor includes a substrate, resistive film, and first and second terminals. The first terminal includes a first electrode. The second terminal includes second and third electrodes. The second electrode is close to the first electrode, and the third electrode is spaced apart from the first electrode. Moreover, the second and third electrodes are electrically interconnected. A kerf may be cut in the resistive material to increase the resistance between the two terminals and eventually substantially electrically isolate the second electrode from the first terminal. Thereafter, kerfs may be cut in the resistive material between first and third electrodes to further increase the resistance between the two terminals.
