Abstract: System for controlling the discharge rate of a material feeder. A weight scale connected to the material is sampled and the samples input to a digital processor. The digital processor determines for consecutive time intervals during discharge of said material, a weight loss over the time interval. The weight loss for the interval is compared with a desired weight loss which is calculated from a desired setpoint material discharge rate obtained only when the weight loss is constant and stable. The resulting error is averaged with subsequent errors to form a control signal for the material feeder. The calculation of errors over each subsequent interval increases the resolution of the control signal, increasing the ability to control discharge rates to compensate for changes in material density which otherwise affect discharge rates.

Abstract: The invention involves a golf club which has a ball striking surface with horizontally extending grooves on it in which the upper edges of the grooves are harder than the lower edges. The upper edges of the grooves on the ball striking surface are selectively made harder either by directional or non-directional surface treatment processes or by making them from materials which are harder than the materials from which the lower edges of the grooves are made.

Abstract: Apparatus including a video baseball-simulating game and a special bat containing a combination of electronic, mechanical, and optical components for providing infrared radiation or other energy (typically electrical) that is modulated when the player swings the bat and thus actuates a centrifugal switch therein. Receiving and decoding means receive the energy and, responsive thereto, provide digital signals to software in the video game to control an animated batter in the visual display therein.An alternative form of the apparatus functions similarly, except that radiation is emitted from, and received at, a "home plate" on the floor and is modulated by the swinging of an ordinary bat to diffract a portion of the radiation in its path from emitter to receiver.

Abstract: An apparatus for the practicing of golf swings utilizing a motion sensor and a radiation source on the forehead of the user which projects a radiated signal when head motion is sensed. The signal is detected by a unit contemporaneously with the golfer's swinging either-a golf club, if he is outside, or a simulated golf club provided with a beam of radiation emanating from one end thereof, if he is inside. In the case of the simulated unit which may be used indoors, details of club head registry, (open, closed, square, sweet spot, slightly toward the toe, slightly toward the heel, toe, heel, top and bottom) swing, follow through, club head speed, tempo, distance the ball travels and the path of the ball are displayed and recorded.

Abstract: The invention involves golf club heads and a method of making golf club heads which comprises forming one or more components of the golf club head from sintered metal powders and then joining the components by welding, brazing, or diffusion or adhesive bonding to form a completed golf club head.

Abstract: An exercise apparatus combined with a video game computer that allows the exerciser to interactively participate in the video game whereby the exerciser's advancement in the video game depends on his rate of exercise and hand-eye coordination. The exercise apparatus provides entertainment and a positive mental distraction from the boring physical exercising experience by enabling multi-sensor feedback between the user and video game simulation. This exercise apparatus has the ability to interface with any exercise device that the user prefers and it will also work with non-equipment exercising methods.

Abstract: The universal carrier of the present invention may be used to move and weigh heavy objects, such as drums or coils of metal or wire. This can be done by changing a removable member attached to the lift member of the universal carrier or by replacing both the removable and lift members with a single horizontally adjustable member. The removable members have different attachments which allow different types of objects to be moved. The universal carrier may include an optional force measuring device which allows the object to be weighed at the time it is moved.

Abstract: An apparatus and method for stabilizing the surface of a food product is disclosed. The apparatus includes a frame, one or two sets of cylindrical rollers in the frame, the sets of rollers being inclined, a mechanism for rotating the rollers, and devices for surface treating the food article. The apparatus optionally may include an enclosure over the frame, and an oil applicator. The devices for surface treating the food article can include a plurality of direct flame applicators, cryogenic liquid gas applicators, impingement hot air applicators, and chemical solution applicators.

Abstract: The invention is a disposable shield for use on surgical scissors to protect surgical personnel from spurting blood when the umbilical cord is cut. It has a generally triangular shield portion and an elongated member with a channel in it so the shield can be easily attached to the arm of the surgical scissors.

Abstract: A fluid temperature monitor comprising a thermosensing unit which is of a size and shape so that it may be readily inserted between the male exit from the fluid coolant pump and the radiator hose connected thereto, thus permitting universal installation in internal combustion engines.

Abstract: Applicant has found that by freezing spermatozoa, especially stallion spermatozoa, in an extender in a flat container having a thickness so that the frozen product does not exceed 4 mm thickness results in a significant increase in the number of spermatozoa surviving upon thawing.

Abstract: The invention consists of an improvement to a four-wheel device used to lift drums with compressed air stored in an on-board storage tank without special straps, tools or clamps that allows the operator to lift the drum with no physical stress and to roll the drum to another location with minimum effort and allows force measuring (weighing) of the drum.

Abstract: The present invention relates to an improved sample injector for use in gas chromatography. The invention also includes a method of injecting a sample onto a chromatographic column, and a method of analyzing a sample using column chromatography and/or mass spectrometry. The improved sample injector features an arrangement to allow a pyrolytic probe to be more easily inserted into the vaporization cavity while permitting the sample to be volatilized in such a way that the sample is more efficiently introduced onto the column. Another feature of the invention is the use of means to reduce the volume of the pyrolysis/vaporization cavity so as to provide efficient throughput of pure sample. Also part of the present invention is a gas chromatograph and gas chromatograph-mass spectrometer which uses the sample injector of the present invention. The present invention includes methods of sample injection and sample analysis using the aforementioned apparatus of the present invention.

Abstract: A method of reconditioning the tracks for rollers of an overhead door by using a machining device to machine down the interior of the tracks and cutting a groove on the interior sides of the tracks whereby a metal insert can be snapped into the grooves on the interior sides of the tracks.

Abstract: A lug casing attached to the side of a drum containing a nonreversing gear which is attached to a threaded cylinder. The nonreversing gear is turned by a worm gear or a pinion gear which is connected to a knob that goes through the side of the lug casing. A T-lug is pulled into the threaded cylinder of the lug casing by the T-lug's accommodating threads. The T-lug fits into a rim on the perimeter of the drum applying tension to a very broad area of the drumhead that is fitted over the edges of a cylindrical drum shell.

Abstract: The present invention is a method for depolymerizing organic vulcanized rubber which contains at least one organic component. In broadest terms, the method of the present invention comprises the steps of: (a) obtaining a portion of organic vulcanized rubber to be recycled; (b) treating the portion of rubber with an effective amount of:(1) a solution of at least one organic hypochlorite; and(2) at least one organic solvent; for sufficient time and at sufficient temperature whereby substantially all of the portion of the rubber is degraded to an extent so as to be dispersed in the organic solvent, whereby the organic component(s) is/are extracted therefrom.The organic vulcanized rubber (such as rubber from used tires and/or other waste sources) may be from a single source or from various sources, and those from various sources may even be comingled for treatment by the present method.
