Title: Powder coating system
Inventor: SALISBURY RICHARD
IPC: B05B5/08
Filed: 1991-02-28
Granted: 2000-11-21
Abstract: An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is tranferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor. During the subsequent pass of the article through the coating zone, the uncoated surface of the article is then covered with powder which is subsequently cured during the second pass of the article through the curing zone. The second coating step for the article may be accomplished by passing the article through the same apparatus as for the first step or by passing the article through a second identical apparatus.
Patent CA-2084999-C (CA)
Inventor: TROKHAN PAUL DENNIS
IPC: B29C59/00
Filed: 1991-06-14
Granted: 1997-05-27
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensi-tive resinous material to the reinforcing structure and pressing the reinforcing structure into a deformable surface, so that the de-formable surface forms protrusions which exclude resin from certain areas which when cured will lie along the backside of the belt, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has trans-parent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure dif-ferential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the em-bryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Abstract: A tightening fixture (10) for tightening a lock nut (165) on a chuck (150) including a torque readout device (240) for measuring the torque applied to tighten the lock nut. The tight-ening fixture includes a stationary support block (12) having a torque transmitting collar (40) rotatively mounted therein. The torque transmitting collar is designed to receive and hold the chuck so that the chuck is held nonrotatable with respect to the collar. When torque is applied to tighten the lock nut on the chuck, the chuck and collar rotate as a unit. A torque indicator (200) is mounted in the stationary block and is responsive to the rotation of the torque transmitting collar to provide an indi-cation of the torque applied to tighten the lock nut.
