Title: Process and reactor for continuously extracting copper from lead
Inventor: BOWERS JOHN EDWIN
IPC: C22B13/08
Filed: 1981-06-18
Abstract: A continuous method and apparatus for removing copper from lead comprises introducing molten lead and sulphur to the upper end of a vertical stirred reaction vessel, maintaining a dispersion of sulphur in the lead without substantial back-mixing and thereafter recovering the dispersion and allowing the formed copper sulphide to float to the surface. The process is suitable for continuous operation on a small scale, e.g. 3 tons per hour, is environmentally acceptable and requires a lead inventory only about one third of that required by conventional batch processes.

Abstract: A thin profile drawer slide apparatus for slidably supporting a heavy drawer in furniture, comprising symmetrical, identical channel members for slidably attaching the apparatus to a drawer and an article of furniture, a plurality of bearings slidably retained in the channel members by bearing retainers, and by an intermediate slide member. The intermediate slide member comprises the unitarily formed combination of a generally vertical central wall, a first bearing raceway joined to an end of the central wall, and a second bearing raceway joined to an arcuate wall extending angularly outwardly from the first bearing raceway, whereby the first and second bearing raceways are vertically and angularly separated. The ball bearings are arranged in four linear, slightly offset sets. Use of a single intermediate slide member with raceways for four separate sets of bearings provides a thin, strong drawer slide for carrying heavy loads. In an alternate embodiment, the central wall of the intermediate slide member comprises a generally rectangular window with a progression roller mounted therein on a vertical axis of rotation. The roller exerts friction on the inner faces of the channel members by compression against the inner faces when the roller is moved. Edges of window act as a detent on the roller and also urge the slide closed when the slide is brought to rest with the roller against one of the edges. The windows relieve compression of the roller when the slide is fully closed. <IMAGE>

Abstract: A method of processing a solid foodstuff by a heating and cooling cycle in which the environmental pressure applied to the foodstuff is controlled during heating so that, at a maximum target temperature, all parts of the body of the foodstuff are conformed to this target temperature due to flow of water, transiently in the vapour phase, from hotter regions to cooler regions. In particular, at least when the target temperature is nominally attained, the pressure is set to the saturated vapour pressure of the foodstuff at the target temperature.

Title: Coded marking on an interior surface of a CRT faceplate panel and method of marking same
Inventor: PEARLMAN SAMUEL
IPC: H01J29/86
Filed: 1995-03-30
Granted: 1999-05-11
Abstract: The novel method for producing a coded marking on a CRT faceplate panel having an exterior and an interior surface with a viewing area surrounded by a periphery and having a luminescent screen with a plurality of different light-emitting phosphors separated by light-absorbing material includes the steps of: depositing a suitable photoresist on the interior surface of the panel to form a layer that extends across the viewing area and onto the periphery; illuminating areas of the photoresist on both the viewing area and the periphery with actinic radiation to selectively change the solubility of the photoresist; developing the photoresist to remove the more soluble areas, thereby exposing underlying portions of the interior surface of the panel, while leaving retained area of less soluble photoresist. The retained areas of the photoresist and the exposed portions of the interior surface of the panel are then overcoated with a light-absorbing material which is dried to form a coating. The light-absorbing coating is developed by removing the retained areas of the photoresist having the overlying light-absorbing coating thereon, while leaving the coating of light-absorbing material adhered to the exposed portions of the interior surface of the panel. The developing step forms openings in the light-absorbing coating on the viewing area and a coded marking, including a pattern of light-absorbing material and open areas, on the periphery of the panel.

Abstract: An extruded scrim having a diamond-mesh pattern is used to construct a personal cleansing implement. The diamond-mesh material is produced from a hydrophobic flexible polymer. The implement comprises a piece of tubular scrim having a longitudinal axis. The tubular scrim is stretched transversely to the longitudinal axis and is gathered parallel to the longitudinal axis to form circumferential pleats. In one embodiment the stretched and gathered tubular scrim is heat set in its expanded and pleated condition. A second piece of tubular scrim is placed inside the pleated and expanded scrim tubing. One end of the second piece is inverted over the outside of the pleats and connected to the other end to envelop the pleated and expanded scrim tubing. In another embodiment the pleats are not heat set and remain resilient. This embodiment has a means for confining the circumferential pleats from axial expansion. A band of material is looped through the scrim tubing and around its outer surface. Pleats are then evenly distributed around the loop to form a toroidal shaped implement. The personal cleansing implement of the present invention has a high open area, without a dense center core to inhibit rinsing and drying.

Title: Cartridge-loading apparatus and method
Inventor: DAVIS MARVIN B
IPC: G11B17/028
Filed: 1995-08-23
Granted: 2000-08-11
Abstract: The mechanism for loading and unloading a disk cartridge uses two sliders (one on each side of a base plate), which move in opposite directions under the influence of a tiller. Each slider has a slot to receive one of the two lifting pins provided on the cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. In this system, the dust door is attached to the cartridge receiver, and the label end of the loaded cartridge remains visible when the disk is loaded. This system may include a bias coil assembly rotatably mounted on an arm so that the bias coil assembly may be loaded into or extracted from the disk cartridge and placed out of the travel path of the disk cartridge. The rotation of the bias coil arm is effected by one of the sliders.

Title: Blanket-selective deposition of CVD aluminum and reflectivity improvement using a self-aligning ultra-thin layer
Inventor: GUO TED-TIE
IPC: H01L23/50
Filed: 1997-03-04
Granted: 2000-04-01
Abstract: The present invention realtes generally to an improved apparatus and process to provide a thin self-aligning layer prior to forming a conducting film layer there over to improve the film characteristics and deposition coverage. In one aspect of the invention, a dielectric layer is formed over a conducting or semiconducting layer and etched to form an aperture exposing the underlying conducting or semiconducting layer on the aperture floor. An ultra-thin nucleation layer is then deposited by either vapor deposition or chemical vapor deposition onto the field of the dielectric layer, A CVD metal layer is then deposited onto the structure to achieve selective deposition on the floor of the aperture, while preferably also forming a highly oriented blanket layer on the field. In another aspect of the invention, a thin , self-aliging layer is formed over a barrier layer prior to deposition of a conducting film there over. It is believed that the self-aligning layer enhances the reflectivity of the films by improving the crystal structure in the resulting film and provides improved electromigration performance by providing <111> crystal orientation. The process is preferably carried out in an integrated processing system that includes both a PVD and CVD processing chamber so that once the substrate is introduced into a vacuum environment, the process occurs without the formation of oxides between the layers.
