Patent number: 5105696Abstract: A method and apparatus are disclosed for punching a cross hole in a workpiece with minimal or no distortion of the hole and the workpiece. According to the method, a cross hole of a given diameter is punched in a workpiece by punching a first hole having a diameter less than the given diameter in the workpiece from a first side thereof, and then punching the first hole again but from a second side of the workpiece opposite the first side at nominally the given diameter to produce the cross hole having the given diameter.Type: GrantFiled: December 10, 1990Date of Patent: April 21, 1992Assignee: Jacobson Mfg.

Patent number: 5076895Abstract: Process and apparatus for recovering clean water and solids from aqueous solids are disclosed. Aqueous solids are mixed with a low viscosity, relatively volatile, water-immiscible light fluidizing oil to obtain a mixture which will remain fluid and pumpable after removal of essentially its entire water content. The mixture of solids, water and fluidizing oil is subjected to a dehydration step by means of a plurality of mechanical vapor recompression evaporators operating in staged array whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered. The light fluidizing oil is then largely separated from the solids. Residual fluidizing oil may be removed from the solids by direct contact with a hot blowing gas such as blowing steam. The invention is characterized by the conservation of energy through the use of heat exchangers whereby condensate gives up its heat to the feed.Type: GrantFiled: June 21, 1990Date of Patent: December 31, 1991Assignee: Hanover Research CorporationInventors: Charles Greenfield, deceased, Robert E.

Patent number: 5069637Abstract: An electrical connector is disclosed which makes connection to one or more unstripped insulated conductors. The connector includes a movable contact assembly disposed in a cavity for movement between open and closed positions. The connector includes a fixed contact electrically coupled to a contact of the movable contact assembly at least in the closed position of the movable contact assembly. The cavity is sealed except for one or more inlets through which one or more conductors are inserted into the cavity for connection. The cavity receives a water-proofing or sealing compound. The connector is constructed so that the cavity volume is constant in both the open and closed positions and during travel of the movable contact assembly. Thereby, compound is not forced out of the cavity when a conductor is connected or disconnected, i.e., when the movable contact assembly is moved. An activator for moving the movable contact assembly is insulated from the contacts of the connector at all times.Type: GrantFiled: June 14, 1991Date of Patent: December 3, 1991Assignee: Jacobson Mfg. Co., Inc.Inventor: Richard C. Baubles

Patent number: 5037333Abstract: An electrical connector is disclosed for receiving a wire wrapped thereto in wire-wrap fashion and a service wire removably connected thereto. In one application, a number of the connectors are mounted to a terminal block and are used to connect wires of a telephone cable, which are wire-wrapped to the connectors, to respective service wires, which are connected to respective connectors by a fastener arrangement. A connector according to the invention includes a first, electrically-conducting piece having an elongated post configured to receive a wire wrapped thereto in wire-wrap fashion and a second piece not directly fixed to the first piece including structure for connecting the service wire to the connector such that the service wire is electrically connected to the first piece, whereby an electrical path is established from the wrapped wire to the service wire through the first, electrically-conducting piece.Type: GrantFiled: November 2, 1990Date of Patent: August 6, 1991Assignee: Jacobson Mfg. Co., Inc.Inventor: Richard C. Baubles

Patent number: 4814589Abstract: Coding systems utilizing machine-readable coding are disclosed. The coding systems are extremely simple to use and preferred embodiments of the machine-readable coding require no external reference or reference code or starting point or orientation for reading or decoding. The number of usable codes for any given number of code elements (bits or digits) is maximized, or, conversely, a minimum number of code elements is required for a given application, thus allowing each code element to be of maximum size for a given coding area. Also, methods and apparatus for encoding objects, and for reading, decoding, processing and using the information obtained from such encoded objects are disclosed. The coding may be applied to objects such as casino chips, currency, automated production line components, consumer products, household items, zip coded objects, etc.Type: GrantFiled: April 18, 1986Date of Patent: March 21, 1989Assignee: Leonard StorchInventors: Leonard Storch, Ernst van Haagen

Patent number: 4790701Abstract: A fastener assembly for floatingly retaining or captivating at least one fastener is disclosed. The fastener assembly includes a flexible channel member with discrete projections extending from opposed flange portions towards each other and at least one fastener having a base which is captivated between the discrete projections and a web portion of the channel member. The projections extending from at least one flange portion are configured to present a camming surface to a fastener base as it is being inserted into the channel member through the opening between opposed projections to cause the channel member to elastically flex and to move at least one flange portion outwardly to permit the fastener base to be seated in the channel member through the opening. The projections are further configured to present removal of the fastener base from the channel member through the opening as long as the channel member remains unflexed.Type: GrantFiled: May 8, 1987Date of Patent: December 13, 1988Assignee: Jacobson Mfg. Co., Inc.Inventor: Richard C. Baubles

Patent number: 4735535Abstract: A locknut having a single-turn thread for securing electrical fittings, threaded conduit and the like to electrical junction boxes and the like is disclosed. The locknut comprises a generally cylindrical portion, a flange portion attached to the cylindrical portion, a plurality of teeth attached to and projecting radially outwardly of the flange portion and axially beyond the end of the flange portion, and a standard thread attached to and extending for substantially only a single turn interiorly of the cylindrical portion. The thread has an included angle corresponding to that of a standard thread, for example, 60.degree.. The teeth seat against a work surface when the locknut is threaded onto the fitting and act as springs which can compensate for a small degree of element loosening by spring recovery. In addition, the thread of the locknut is flexible so that both the teeth and thread act as springs working in conjunction with each other.Type: GrantFiled: March 11, 1985Date of Patent: April 5, 1988Assignee: Jacobson Mfg. Co., Inc.Inventor: Richard C. Baubles

Patent number: 4553415Abstract: A locking device to be locked onto the kingpin of a trailer to prevent its being engaged by the fifth wheel of an unauthorized tractor. The locking device closely encircles the kingpin and houses within an aperture a locking bar that is adapted to be pressed into engagement with the kingpin recess or groove. The outer wall of the locking device casing has a protrusion in the area of the locking bar aperture such that the locking bar and the locking unit disposed therein are recessed within the aperture and thereby protected. The locking bar aperture from the outer end of the locking bar when in the locked position to the outer wall of the protrusion on the casing is counterbored beyond the transverse cross-section of the locking bar.Type: GrantFiled: November 16, 1984Date of Patent: November 19, 1985Inventor: Constant O. Maffey
