Patent number: 6481765Abstract: A security seal with a male part having a security wire extending from it, and a female part that receives the male part. The security wire passes through two grooves on the male part and through a central opening between them. With the security wire so placed, the male part is inserted into the female part where two pairs of resilient spurs on the male part engage knobs in the female part preventing the male part from being removed and a protective cover on the male part receives the female part. The security wire preferably has a metal base with a thin metal thread spirally tightly wound around it that is separable from the metal base when the security wire is violently pulled or bent. The seal is preferably made of a transparent material and preferably has a thread connecting the male and female parts so they stay associated.Type: GrantFiled: March 13, 2001Date of Patent: November 19, 2002Inventor: Ivan Jelavic

Patent number: 6305656Abstract: A magnetic coupler having various holding device embodiments to be quickly magnetically coupled and uncoupled with an industrial strength magnetic base that is fixedly attached to a desired nonferrous surface, such as a dashboard of an automobile. The magnetic base includes a nonferrous low or soft durometer shell that encases the magnet. Preferably, the shell's outer surface is textured, which provides friction for superior magnetic coupling with a ferrous disk. If the device to be held is relatively heavy or has a high profile, the holding device/object to be held includes a support collar assembly that is fixedly attached to an external portion of the holding device.Type: GrantFiled: December 3, 1999Date of Patent: October 23, 2001Assignee: Dash-It USA Inc.Inventor: Roy D.

Patent number: 6257673Abstract: A percussion or hammer tool bit (20) having a substantially rearward shank portion (24) of a first diameter (ds) and an elongated substantially uniformly cylindrical forward tool portion (26) having a second diameter (dt) in the range of 15-20% greater than the diameter of the rearward shank portion. The overall tool length (Lo) is 90-95% of the overall tool length of the prior art (Lopa). The combination of the increased diameter of the forward tool portion and the decreased length of the overall tool length (relative to the prior art) provides substantially the same or greater mass than the prior art tool bit when the tool bit is used percussively, but is less likely to flex, which reduces the likelihood of stress fracture failure. The forward portion (26) includes a striking face (30), such as a blunt (31), moil point (31′), or chisel (31″).Type: GrantFiled: October 27, 1999Date of Patent: July 10, 2001Assignee: Ramco Construction Tools, Inc.Inventors: David J. Markham, William D. Blackburn

Patent number: 6174160Abstract: Method and apparatus to prevaporize and premix liquid and/or gaseous fuels with air in two stages at two different temperatures prior to combustion. The invention is directed to the entry of a finely atomized liquid fuel, such as No. 2 diesel, into an inlet end of an annular chamber. Air is mixed with finely atomized liquid fuel, preferably generated by a small flow number liquid fuel nozzle, in a first chamber of the annular chamber at a first (relatively high) temperature for a relatively long residence time. The air and liquid fuel is moved into a second chamber of the annular chamber where a secondary hotter air is injected into the annular chamber by a plurality of staggered high velocity jets to prevaporize and premix the combined fuel and air mixture at a second higher temperature, but for a shorter time. The intense prevaporization and premixing make the mixture suitable for entry into a combustor, but without the need to add water or steam to keep pollutant emissions low.Type: GrantFiled: March 25, 1999Date of Patent: January 16, 2001Assignee: University of WashingtonInventors: John C. Y. Lee, Philip C. Malte

Patent number: 6047980Abstract: A manual two-speed wheelchair having a chair, frame, fixed wheel axles, and wheel assemblies. The wheelchair is capable of driving in a direct (1:1) power mode and a lower gear mode without shifting. A separate secondary input assembly provides for reduced gearing, one secondary input rim assembly per wheel assembly. The secondary input assembly includes a toothed driver gear, a toothed driven gear, and toothed belt. The driver gear and driven gear are offset from each other. This is accomplished by an offset arm. The secondary input assembly drives the driver gear, which, in turn, drives the belt, which, in turn, drives the driver gear, which is fixedly attached to the wheelchair wheel assembly.Type: GrantFiled: January 7, 1999Date of Patent: April 11, 2000Assignee: University of WashingtonInventors: Anthony Margherita, Amand Cousins, Rebecca A. Aleshire, Khaled Al-A wadhi, Myke J. Woodwell, Jean Livesay

Patent number: 6026514Abstract: Apparatus and a method for converting a conventional crew cap into a tubular article of outerwear. The crew cap includes a flexible outer layer and a flexible inner layer that together forms a crown portion and an opened end. An opening is positioned on and defined by either the inner layer or outer layer. In a first use, the open end of the inner layer is adapted to be worn by a wearer such that the crown portion of the inner layer covers the wearer's crown. To convert the cap into tubular article of outerwear, the layer not containing the opening is completely pulled through the opening to form a tubular article of outerwear having a first and second open end. The tubular article is adaptable to be worn by the wearer as a headband or neck warmer.Type: GrantFiled: November 30, 1998Date of Patent: February 22, 2000Inventor: Mark E. Fricker

The timers along with the door state determine whether the armed state or unarmed state is in effect. Controller (26) sends output signals to activate the alarm system when the door (16) is opened by an unauthorized user. An authorized user inputs a deactivating code into the keypad (32) to deactivate the alarm system. Optional LED mail deposit indicator, latching (locking) mechanism, and illuminating lights(s) may be provided.Type: GrantFiled: June 16, 1998Date of Patent: June 29, 1999Inventor: James H. Baggarly

Patent number: 5788293Abstract: A separator for separating gold particles from ore including a rotatable pan, and frame for mounting the pan through a recessed hub cup assembly at an angle from horizontal. The pan includes a frusto-conical side wall. The pan inner surface also includes a riffle spiraling inwardly from the outer end of the side wall to create loops that spiral to the hub cup. The riffle and the pan inner surface form a slide track in which the gold particles move along the riffle to reach the hub cup. One of the improvements includes a plurality of agitator knobules that are positioned between the loops of the riffle. Another feature is an easily removable insert cup inside the hub cup for easy collection of gold. In use, ore is introduced into the pan during rotation. Particles are agitated by the knobules to separate the particles from the ore and aid the particles down the slide track, moving the particles inwardly along the riffle into the insert cup.Type: GrantFiled: June 6, 1997Date of Patent: August 4, 1998Inventor: Leo M. Krenzler

Patent number: 5754109Abstract: A sensor that senses the absence of a high-magnetic permeable coin box (10) that, in its quiescent state, is mounted within a compartment (12) of a coin operated device, such as a pay telephone (14). The compartment has at least one interior surface (16). The sensor includes an electromagnetic switch (20) having two states (open circuit, closed circuit) that affect a signal to an output device (22) when the switch (20) is activated from one state to another. In preferred form, the switch (20) is a reed switch. A magnet (18) normally provides magnetic flux flow to the switch. When the magnetic flux flow is disrupted, the switch (20) changes from one state to another. The switch (20) and the magnet (18) are fixably-connected to at least one surface (16) of the compartment (12).Type: GrantFiled: June 14, 1996Date of Patent: May 19, 1998Assignee: Foursum International, Inc.Inventor: Brian M.
