Patent number: 4512586Abstract: A packing arrangement for sealing an area about a shaft in a structural body includes a plurality of V-shaped packing rings in stacked alignment. The packing rings are made from a memory retainable material and preformed into the V-shaped configuration with a forming die. After being preformed, the V-shaped packing rings are compressed beyond their preformed configuration and placed in a packing chamber. The memory characteristics of the packing ring material are such that the rings are urged toward their preformed V-shape to compensate for any dimensional instability of the rings during thermal cycling. The packing rings also have a very small stack height and provide an increased number of sealing surfaces within a predetermined sealing area.Type: GrantFiled: May 18, 1984Date of Patent: April 23, 1985Inventor: Russell G.

Patent number: 4367149Abstract: Iodine has long been known for its bactericidal, viricidal and cysticidal activities. Recently it has been attracting attention as an agent in water purification. Water purified with iodine is nevertheless subject to some objections. Because of its displeasing appearance iodine treated water is esthetically unacceptable. In the case of drinking water, color, odor and taste of water purified with iodine are even more detracting. The process herein overcomes these disadvantages, yet iodine, with its germicidal advantages, can still be used.Type: GrantFiled: April 8, 1981Date of Patent: January 4, 1983Assignee: R.N.K.

Patent number: 4074467Abstract: A multimodal cycle for a grinding machine is modified as the function of the grinding force and the mode of operation. The grinding force is monitored by measuring the electrical load value upon the grinding wheel motor during operating conditions and biasing this value by a stored value representative of the nongrinding idle load. The idle load bias is updated with each grinding cycle and the grinding force signal is used to control a variety of machine operations. If the grinding force signal exceeds a predetermined threshold during an early portion of the grinding cycle, the wheelhead advancement is terminated; while the same situation in a later portion of the cycle permits continued wheelhead advancement but at a reduced rate. The grinding force signal is also used to count parts and detect part absence. It is further used to regulate rough and finished spark-outs as well as a peak load limit for the grinding cycle.Type: GrantFiled: March 14, 1977Date of Patent: February 21, 1978Assignee: Cincinnati Milacron-Heald CorporationInventor: Edward George Robillard
