  • Hydraulically controlled chiropractic table
    Patent number: 4582311
    Abstract: A chiropractic table that is hydraulically controlled for variable tension flexing. The pelvic section of the table is tilted by a hydraulic system that employs an accumulator which provides for control of manually-applied procedures. The use of hydraulics also requires less space than mechanical means thereby permitting additional functions to be combined into a single all-function table.

  • Wire mesh flooring
    Patent number: 4573432
    Abstract: A wire mesh floor for use in hog houses.

  • Safety hitch pin
    Patent number: 4555125
    Abstract: A self-locking, safety hitch pin for connecting the tongue of a farm implement to the drawbar of a towing vehicle, such as a tractor. The pin has a handle pivotally connected to it at its upper end, the handle extending to the lower end of the pin to prevent it from inadvertently falling out of the connection. A spring-biased locking member is combined with the upper end of the handle and pin to automatically lock the handle in place when the handle is lowered to a closed position.

  • Ultrasound needle, biopsy instrument or catheter guide
    Patent number: 4497325
    Abstract: An attachment for use in connection with ultrasound transducers to assist in conducting various surgical procedures involving the withdrawal of fluid from or injection of fluid into selected body organs or biopsies of various organs. The attachment serves to accurately guide a needle or catheter into the selected site scanned by the ultrasound transducer. The device employs a removable and rotatable guide that provides for the use of instruments of different sizes for insertion in body parts within a wide range of angles.

  • Apparatus for stuffing ground meat into casings
    Patent number: 4484374
    Abstract: An apparatus for stuffing ground meat into casings so as to form links. The apparatus has a metering pump for the ground meat, which pump includes an impeller combined with a movable, adjustable vane that controls the volume of meat fed into the stuffing horn for introduction into the casing. The stuffing horn has ribs along its length which ribs make it easier to slip the casing onto the horn and prevent the casing from slipping when the horn is turned to twist the casing and form the links.

  • External compression bone fixation device
    Patent number: 4456005
    Abstract: An improved external compression bone fixation device for use in the treatment of fractures. The device provides compression on a bone fracture until the fracture has healed. By threading a screw with a threaded shank into the far side of the fracture and then threading a second screw into the other portion of the fractured bone and also onto the shank of the first screw, the fracture is drawn together. When healing has been completed, the screws are removed. The entire procedure can be performed from outside the fractured limb, and a second surgical procedure is not necessary to remove the fixation device after healing.

  • Hog finishing building
    Patent number: 4442792
    Abstract: A finishing building for hogs designed to defer to the natural laws of biological behavior. The building design allows the hogs to satisfy their exploratory drive while still providing areas for the hogs to rest, feed, etc. if they wish. The design of the building provides multiple rest areas physically separated by low walls but connected by passageways that allow the hogs to wander from area to area. Also, the rest areas are physically separated from the feeding areas, and the waste areas are also separate. The building employs the module concept, and when a number of the modules are combined into a single building, a maze effect results which produces both the nook desired for the rest areas while allowing the hogs maximum room to explore. The building also has a unique design which provides heating, cooling and ventilating of the interior without supplemental equipment.

  • Method and apparatus for computing data for producing photo prints
    Patent number: 4423952
    Abstract: A method and apparatus as described for determining the correct exposure time for either black and white or color negatives or positives. The apparatus fully automates the printing process by taking into account all necessary factors thus assuring first print capability. The density of the equipment light, the film and the filters are all measured at the same time and result in a single readout which will be the correct density-exposure time.

  • Limb exercise device
    Patent number: 4407496
    Abstract: An exercising device for use in strengthening, conditioning and rehabilitating body joints such as the knee and shoulder. The device is used in connection with conventional exercising apparatus to minimize detrimental shearing forces on the joint during the exercise procedures. This is accomplished by replacing the conventional single contact pad on the limb with two contact pads or pad and handgrip mounted on a variable fulcrum that will produce the desired counterforce to the shearing force on the joint.

  • Adjustable basketball goal
    Patent number: 4395040
    Abstract: An adjustable basketball goal is mounted on a parallelogram supporting structure that permits the goal to be adjusted to different heights from 6 to 10 feet. The goal is raised and lowered by threaded members between portions of the supporting structure that provide sufficient mechanical advantage so that the adjustment can be easily made. The supporting structure also is designed to permit the goal to be secured directly to the supporting structure rather than just the backboard thereby minimizing the breaking off of the goals by a player hanging onto the rim. An adjustable length tension member extends between front and rear vertical supports of the supporting structure to take up slack in the structure as its pivotal connections wear with age.

  • Stairs and method of making the same
    Patent number: 4367613
    Abstract: A construction for wooden stairs that permits standardized, factory machined components to be pre-packaged and shipped to the job site where they can be installed to fit almost any installation. The structure includes stringers which have riser and tread receiving grooves on both sides. The grooves on each side of the stringer provide for a different rise and run rate. The construction technique and the resulting stairs substantially reduces the job-site layout and assembly time from that required with conventional stairs. It also reduces the number of components that must be produced and stocked. The technique is especially applicable when employed with wooden stairs of the interlocking type that generally need no fasteners, adhesives or wedges.

  • Weight lifting machine
    Patent number: 4358107
    Abstract: A weight lifting machine substitutes a noncumulative force or constant tension type spring for some of the individual weights with which the machine would otherwise be equipped, the tension required to unwind the spring being equal to the sum of the omitted weights. The remaining individual weights function as before but when additional resistance, greater than their sum, is wanted, the spring is connected into the lifting mechanism.
