Patent number: 6813963Abstract: A transducer for measuring the relative velocity of movement of a body in a liquid or gaseous medium employs no reciprocating parts and functions by sensing the force applied to a diaphragm (6) die to its movement through the medium or the movement of the medium towards the diaphragm. The speed transducer makes use of a Hall effect solid state device (7) that produces an output when a magnetic field is applied to either of its surfaces. The level of the output voltage is proportional to the velocity of movement in the positive direction, i.e. when the force acts on diaphragm (6) in (FIG. 1). Since the transducer takes into account differential forces, an unwanted common force acting on both diaphragms simultaneously will have no effect on the measured speed. The tubular body (1) in which the Hall effect device is located may be made from any non-magnetic material suitable for the environment in which the transducer will be used.Type: GrantFiled: July 30, 2003Date of Patent: November 9, 2004Inventor: Wilfred Ignatius Bishop

Patent number: 6813986Abstract: A reusable bomb diffusing device having a core structure with outer surfaces covered by outwardly extending and increasingly upwardly-directed energy-absorbing vanes that are fixed in position and separated from one another by approximately 3°, the core structure being centered within an outer chamber having solid side walls and a mesh top surface through which the rapidly expanding gases from a blast are exhausted. A central bottom opening in the present invention permits placement directly over a bomb, with movement of the device to a bomb's location being accomplished manually or via attachment to a motorized vehicle. Expanding gases within the core structure are directed to the vanes in vector geometry fashion, which reduces the gases' energy and drives them upward to exit the outer chamber through the openings in its mesh top. During detonation, the present invention device remains substantially in its pre-explosion position. Police and military applications are contemplated.Type: GrantFiled: November 27, 2003Date of Patent: November 9, 2004Assignee: Counterterrorism Technologies CorporationInventors: Samuel Barran Tafoya, Hans Guenter Broemel

Patent number: 6813991Abstract: A load-transmitting arrangement (14) with articulated function for taking up and transmitting a pedal force, in particular a brake pedal force, is described. A braking device (10) of a brake system comprising the load-transmitting arrangement (14) is further described. The load-transmitting arrangement (14) has a first load-transmitting member (20), which has a receiving sleeve (20A) for a second load-transmitting member (22), an end of the second load-transmitting member (22) that projects into the receiving sleeve (20A) engaging behind a snap element (30B), which locks the second load-transmitting member (22) against withdrawal from the receiving sleeve (20A). The end of the second load-transmitting member (22) that engages behind the snap device (30) is a joint head, which is supported pivotally inside the receiving sleeve (20A). The second load-transmitting member (22) is coupled movably to a support device (32), against which the snap element (30B) is non-pivotally supported.Type: GrantFiled: September 3, 2003Date of Patent: November 9, 2004Assignee: Lucas Automotive GmbHInventor: Boris Köth

Patent number: 6813992Abstract: A baking oven comprises a charging section with an inlet for dough pieces to be loaded; a baking chamber; and a discharging section with an outlet for baked dough pieces to be unloaded. Provision is made for a circulating-air arrangement with a source that generates a flow of circulating air, a circulating-air heating device, and a circulating-air guiding channel, sections of which are formed by the baking chamber. An outer wall of the baking chamber is rotationally symmetrical about a vertical axis of rotation, expanding steadily upwards in particular in the shape of a funnel. A baking oven results, in which the dough pieces can be moved and distributed as regularly as possible during baking.Type: GrantFiled: September 29, 2003Date of Patent: November 9, 2004Assignee: Werner & Pfleiderer LebensmittelteHchnik GmbHInventors: Frank Blümel, Bernd Dannenhauer, Dieter Knost

Patent number: 6813994Abstract: A compartmented cooking device for simultaneously cooking a plurality of articles on a flat heated surface has an outer wall around the perimeter of an area and at least one internal wall within the area for defining a plurality of compartments for receiving a material to be cooked and for maintaining the material separately on the heated surface. The compartments can be all of substantially equal area and shape, such as square, rectangular, triangular, rhomboid, trapezoid, circular, oval or any other shape, and are all open from both an upward direction and a downward direction. The walls of each compartment should have at least one marking thereon for delineating a desired level for insertion of material to be cooked. The device also has a handle for allowing it to be lifted off the griddle without a user having to touch the walls of the device.Type: GrantFiled: September 30, 2002Date of Patent: November 9, 2004Inventor: Brian Williams
