Abstract: A combination base plate and heat exchanger accessory are inserted into an existing cooking grill between the cooking area and the heat source of the cooking grill to suppress or prevent flame flare-ups caused by ignition of drippings. The bottom surface of the base plate is disposed in close proximity to the heat source of the cooking grill. The heat exchanger has an upper surface that is corrugated or channeled, to catch drippings and conduct them away from the surface of the heat exchanger to a drip edge disposed along a perimeter edge of the heat exchanger. The drippings are thus prevented from contacting the heat source of the cooking grill and causing flame flare-ups which may singe or burn the foodstuff being cooked.

As the steering helm assembly is rotated, a set of cables extending from the cable support adjacent to the steering helm assembly activates the vehicle engine. Upon rotation of the steering wheel a given degree in a clockwise or counter-clockwise direction from a straight alignment of the vehicle, a set of cables extending from the cable support to the slide couplers activates the vehicle engine.

Abstract: A boat featuring an autopilot-based steering and maneuvering system. The steering system uses a specially integrated autopilot that remains engaged unless the operator is actively commanding the boat to change course. For example, in a boat in which steering is performed using a joystick, course changes can be effected simply by moving (e.g., twisting) the joystick. That movement automatically disengages the autopilot, allowing the operator to achieve the course change. When the operator has completed the course change and released the joystick, a centering spring returns it to a neutral position and the autopilot automatically reengages. In the improved maneuvering system, the autopilot is used for controlling the direction of a waterjet boat during very low speed (e.g., less than 4 knots) maneuvers, such as docking. The autopilot controls the steering system, e.g.

Abstract: The invention relates to a device and a method for spray extrusion, more particularly for application of a surface coating “under-up” onto car bodies. The surface coating may be a PVC abrasion protection material, a joint sealant or the like, and is generally a low-viscosity material. The invention comprises a source of coating material connected to a nozzle for spraying the material onto an object. According to the invention, the nozzle has a discharge aperture in the form of a pattern of holes (5), preferably a row of holes. Through this reduction of the discharge area, a raised pressure is created in the nozzle, causing the material to be sprayed out of the nozzle onto the object at a relatively high discharge velocity. The invention allows a higher pressure and a simpler and more reliable coating method.

Abstract: The disclosure relates to a vaporizer valve which accepts a carrier gas and a pressurized liquid and forms a mixture of the carrier gas and vaporized liquid. An internal cavity receives the carrier gas through a carrier aperture and the liquid through a liquid aperture, and the mixed gas and vapor are exhausted out of the cavity via a third aperture. A moveable diaphragm disposed adjacent to the liquid aperture forms a vaporization region having a pressure gradient. The liquid passing through this pressure gradient vaporizes due to expansion. By controlling the diaphragm position with a feedback control circuit responsive to a liquid flow rate monitor, the liquid flow rate may be controlled independently of the carrier gas flow rate.

Abstract: A steel blade for turbomachinery, for example, a vane or blade of stainless steel for a steam turbine, has its working surface smoothed, for example, by tumble polishing, to a smoothness of about 0.25 microns Ra or less. Then the smoothed surface is subjected to plasma nitriding to harden the surface to a value of, for example, about 1000 on the Vickers hardness scale. The hardened nitrided layer in the steel can be 25 to 100 microns thick. The plasma nitriding process does not affect the smoothness of the area of surface being nitrided, and the resultant surface hardness preserves smoothness of the surface while the blade is in use.

Abstract: An economical process that combines bentonite, or similar clays, that form a clump when in contact with cat urine, with waste cellulosic fibrous materials, preferably paper mill sludge, to form a light weight scoopable (clumping) cat litter product. In the process, paper mill cellulose waste is combined with bentonite clay (preferably sodium bentonite) in a mixing auger in varying percentages depending upon the desired end weight of the finished product, transferred to a secondary rotating drum mixer, then to a rotating drum dryer, and from the dryer to a screening process. The finished product is a granule weighing between 20 lbs./cubic foot and 50 lbs./cubic foot. The granule is highly absorbent and capable of forming a distinct clump that can be separated from the surrounding granules without falling apart. A unique characteristic of the process is the combination of heavy clay particles with light weight cellulose particles to form a new composite particle.
