  • Patent number: 4237370
    Abstract: A pulse generator for metal machining by electric discharges, comprising a primary current circuit for producing and transmitting pulse forms to a pair of electrodes. A voltage and/or current source is arranged in the low-ohm and low-loss primary current circuit, the voltage of which has a value which is only that much greater than the operating voltage of the pulses flowing through the spark gap as is needed to positively overcome the voltage losses occurring in the primary current circuit. A signal generator produces a signal corresponding to the desired current pulse shape or form. A comparator, which has a switch arranged in the primary current circuit for regulating the current flow in such primary current circuit, controls the current flowing through the primary current circuit, as a function of the desired pulse form produced by the signal generator and a magnitude of the current flowing in the primary current circuit which is tapped-off by a measuring feeler.

  • Patent number: 4230097
    Abstract: A breathing and acceleration protection apparatus for the pilot of a fighter aircraft includes a source of pressurized respiratory gas (typically a liquid oxygen converter) and an anti-g regulator valve means fed by the source and connected to inflatable trouser pockets of a g-suit carried by the pilot. A demand regulator delivers respiratory gas to the pilot. The anti-g regulator valve includes an inertia body movable responsive to acceleration along a predetermined direction for increasing the pressure in the pockets and when an amount of acceleration in excess of 2 g is sensed. Additional means responsive to the aircraft altitude establish a static pressure in the pockets at a value which increases with altitude in the absence of acceleration.

  • Patent number: 4222150
    Abstract: Apparatus for peeling sausages comprises means for feeding a chain of sausages in the longitudinal direction of the chain towards a pair of counterrotating rollers defining between them a roller nip located in the plane of symmetry between the rollers. The feeding means causes the leading end of each sausage in succession to meet the roller surfaces on either side of the plane of symmetry and at an obtuse angle to the longitudinal direction of the nip. Before each sausage meets the roller surfaces its casing has been slit by a knife, and due to their rotation the rollers grasp the slitted casing and pull it through the nip for removal separate from the skinned sausages which move along the rollers on the infeed side thereof until they are discharged at the end of the roller nip.

  • Patent number: 4221240
    Abstract: An apparatus and method for absorbing a portion of the moisture removed from material woven on a fluid-jet loom. A shed of warp yarns is formed in the loom and a fluid jet is used to feed weft yarns into the warp yarns for forming a length of woven material. An opening extends at least the width of the length of material, and the material is moved over the opening. Air is pulled through the opening for removing moisture from the length of material as it moves over the opening. The air has a temperature greater than that of the surrounding atmosphere. The improvement includes reducing the temperature of the moisture-laden air to at least the dew point of the surrounding atmosphere for reducing the moisture content of the air before the air enters said surrounding atmosphere.

  • Patent number: 4220032
    Abstract: A reciprocating preferably transparent break guard is disclosed for use in connection with a reciprocating machine, such as a bending machine. Adjustable switching means are operatively associated with the machine for controlling the actuation of a hydraulic piston connected to a frame for the guard. When the machine is in its upper position for receiving a workpiece, the switching means causes the piston to be actuated to maintain the guard in its upper position free from interference with the break. When the machine is actuated and starts its downward stroke, the switching means actuates a solenoid to release the piston causing the guard to drop smartly in front of the break thereby preventing the operator from accidentally inserting hands or fingers into the break of the machine. In its lowered position, the machine again actuates the switching means to operate the piston to raise the guard to its upper position.

  • Patent number: 4217739
    Abstract: A storage bin is disclosed for storing a flowable material such as an agricultural commodity in a water-impermeable environment which is particularly suited for the storage of grain. The bin includes a liquid impervious, preferably cone-shaped, integral liner supported substantially and entirely by a cavity in the ground adjacent to and beneath the liner. A foundation, which includes a footing supported by the ground adjacent the footing, is located relative to the liner so that an upper lip portion of the liner is secured to the footing. An above ground storage portion of the bin is directly secured to the footing so that the bin construction eliminates the cost of material in steel hopper bottom and concrete hopper bottom bins. A hopper for receiving material and directing it to an unloading auger within the bin is located at the apex portion of the inverted cone-shaped liner. A method of constructing a storage bin of the type described is also disclosed.
