Patent number: 10377093Abstract: A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.Type: GrantFiled: December 16, 2015Date of Patent: August 13, 2019Assignee: Gear BoxInventor: Rafael G.

Patent number: 4993276Abstract: A drive assembly brake is mounted in the gearbox connecting a motor driven input shaft to an output shaft, the output shaft being connected by a tubing string to a submersed rotary pump. The gearbox includes an output shaft housing portion defining an oil chamber and an input shaft housing portion defining an oil-free centrifugal brake chamber. The relatively faster moving input shaft carries a centrifugal brake having weight members frictionally engageable with the brake chamber wall when the rotational speed of the input shaft reaches a sufficiently high degree, and the resulting braking action retards the rotation of the input shaft.In one embodiments a split casing gearbox is used having matched passage portions in the faces of the connected gearbox portions to form a lubrication passage system for the shaft bearings.Type: GrantFiled: March 13, 1987Date of Patent: February 19, 1991Assignee: Superior Gear Box CompanyInventor: Wallace L. Edwards

Patent number: 4434606Abstract: This compact gear box is intended for a corn harvesting unit having a pair of harvesting rolls and a pair of gathering chain assemblies. The gear box includes a drive shaft and first and second pairs of shafts connected to the harvesting rolls and the gathering chain assemblies respectively. The drive shaft includes a bevel gear driving a bevel pinion gear mounted to the end of each of the first pair of shafts to rotate the harvesting rolls. The first shafts each include worm gears and the second shafts each include worm wheels engageable by associated worm gears of the first pair of shafts to rotate the gathering chain assemblies.Type: GrantFiled: May 4, 1982Date of Patent: March 6, 1984Assignee: Superior Gear Box CompanyInventors: Lawrence G. Rhodes, John W. Carter
