Patent number: 5632232Abstract: A pet training system incorporating a transmitter and a pet collar. The transmitter includes a radio-frequency signal generator, with a power supply, for generating a low amplitude RF signal; the RF signal is applied to a radiation antenna, through appropriate connectors, so that the transmitter radiates an RF field in or around a designated area the pet is intended to avoid. The pet collar includes a receiving antenna and a shock device or other deterrent device actuated when the pet, wearing the collar, approaches the designated area. The radiation antenna includes at least three and preferably as many as eight or more series connected conductors so that the RF field extends an appreciable distance from the radiation antenna.Type: GrantFiled: January 23, 1995Date of Patent: May 27, 1997Assignee: Waters Research CompanyInventor: Michael A.

Patent number: 5628237Abstract: A high speed slicing machine supports first and second food loaves for movement along parallel loaf paths into a slicing station where both loaves are sliced by one cyclically driven knife blade; the slices are stacked or shingled in groups on a receiving conveyor located below the slicing station. Independent loaf feed drives are provided; slices cut from one loaf may be thicker than slices from the other. The machine combines manual and automated mechanisms to load food loaves onto the food paths. These mechanisms share a central barrier that is used only during loading; at other times the barrier is clear of the loaf paths. The automated loaf loading mechanism has a sweep to push one or more loaves onto a support defining the loaf paths. There are two grippers, one on each loaf path; each grips the end of a loaf remote from the slicing station.Type: GrantFiled: October 11, 1994Date of Patent: May 13, 1997Assignee: Formax, Inc.Inventors: Scott A.

Patent number: 5612224Abstract: A process for measuring the quantity of lead on the waterway surface of a brass component, for example a brass plumbing fixture, includes the steps of filling the brass component waterway with an aqueous solution of an acid which removes lead from the surface of the brass component. The acid solution is removed from the waterway after a time period which is sufficient to remove substantially all surface lead from the brass component, but which is insufficient for the acid to remove significant surface zinc and copper to expose surface lead. The quantity of lead per unit surface area of the brass component can then be determined by the use of the volume of the acid solution, the surface area of the brass component and the concentration of lead in the acid solution.Type: GrantFiled: December 5, 1995Date of Patent: March 18, 1997Assignee: 21st Century Companies, Inc.Inventor: Timothy J. O'Brien

Patent number: 5611524Abstract: An adjustable elastomer bias device includes a base member (metal or rigid plastic) having plural receptacles for receiving one end of each of a like plurality of bendable, resilient, elastomer rods. An index member is included in the device; the index member has plural rod guide passages and each elastomer rod passes through one guide passage so that the index member can slide longitudinally along the rods, toward and away from the base member. The index member is anchored at one of several displacement distances from the base member to change the effective stiffness (bias) of the rods. The index member may be rotated for torsional bias or moved laterally for linear bias to effect a further bias adjustment; a retainer holds the additional bias adjustment. The bias force of the device results from bending of the elastomer rods.Type: GrantFiled: June 1, 1995Date of Patent: March 18, 1997Assignee: Gordon Research & Development, Inc.Inventor: James R. Gordon

Patent number: 5611105Abstract: A floor scrubber has four wheels for stable support on the floor. These wheels are attached to the underside of a resilient molded plastic frame so that any vertical movement of any of the wheels is transmitted directly to the frame. The frame is ribbed to be stiff in longitudinal bending, but torsionally the frame is somewhat flexible. The scrubber body, which is attached to the upper side of the frame and is supported by the frame, is also a molded plastic part which is somewhat flexible. The weight of the body and its contents keeps all four wheels on the floor at all times, even when the floor is uneven, by flexing the frame and body as needed. This structural flexibility eliminates any need for an additional means to keep all the wheels on the floor, such as a sprung suspension or a center pivoted axle.Type: GrantFiled: January 13, 1995Date of Patent: March 18, 1997Assignee: Tennant CompanyInventors: Michael L. Blehert, Robert A. Geyer

Patent number: 5609109Abstract: A rail car truck side frame for use in a frame brace truck which has stabilizing cross braces extending between the side frames. The side frame has a top compression member and a bottom tension member which are joined by upwardly and outwardly slanted end walls. There is a bracket at the lower end of each end wall for use in mounting a cross brace. The bracket includes first, second and third walls, each integral with the side frame and each extending downwardly from the side frame. The first wall forms the wall for attachment of a cross brace with the second and third walls being perpendicular to the first wall and forming support for the first wall.Type: GrantFiled: September 11, 1995Date of Patent: March 11, 1997Assignee: Standard Research and Design CorporationInventor: Thomas R.

Patent number: 5607717Abstract: An applicator for seed treatment products includes an elongated, cylindrical tube having an enlarged flange at a top end for receiving a canister of treatment products. The bottom end of the tube is inserted into a seed hopper filled with seeds, the tube penetrating beneath the surface of the seeds. A canister of treatment products is opened at one end and inserted into the flange with the open side down. The canister fits snugly in the flange so the treatment products can escape only from the bottom of the tube which is within the seed pile. The user stirs the pile with the tube to distribute the treatment products evenly throughout the pile.Type: GrantFiled: November 30, 1995Date of Patent: March 4, 1997Assignee: Trace Chemicals IncorporatedInventors: Gary Grossweiler, Timothy McArdle
