Title: Fuel machine delivery system for wet scrape whilst maintaining tool orientation
Inventor: HENRY PATRICK THOMAS
IPC: G21C19/20
Filed: 1990-09-27
Granted: 2000-11-14
Abstract: Apparatus for remotely obtaining sample scrapings from the inner surface of a fuel channel of a nuclear reactor with coolant in the fuel channel. A sampling tool is introduced into a fuel channel. The sampling tool has a cylindrical casing in which are mounted cutters for obtaining the scrapings. Forward movement of a central shaft in the sampling tool actuates the cutters in sequence to project through a slot as they move forwards and the sample scrapings fall into sample receiving pockets in the sampling tool. A pusher having a cylindrical casing of substantially the same inner diameter as the inner diameter of the fuel channel has a floating plunger mechanism with a sliding internal housing mounting a plunger rearwardly biased in the housing. The ram head of a fuelling machine engages the trailing end of the plunger, moves the housing forwardly until it stops against the casing of the sampling tool and then advances the plunger to cause forward movement of the central shaft of the sampling. tool to obtain the scraping.      A preferred form of the apparatus obtains sample scrapings at desired orientations. For example, it obtains scrapings at desired ones of a 11:00 o'clock, 12:00 o'clock or 1:00 o'clock orientations. An orientation device is installed in the end of a fuel channel and it has a rotatable ring which may be rotated to one of three selectable positions corresponding to respective ones of the 11:00 o'clock, 12:00 o'clock and 1:00 o'clock orientations: A ring key on the orientation device cooperates with a keyway in the sampling tool to orient the sampling tool.

Abstract: Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame of them are intraframe coded and then transmitted.      Remaining digital video signals are interframe coded with reference to the digital video signals, intraframe coded, and the digital video signals, intraframe coded, of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a frame which is frames away from the reference frame is converted to motion vector per one frame between the reference frame and the frame, is optimized, and is then transmitted.

Granted: 2000-02-01
Abstract: 1. Process and apparatus for producing (cigarette) packs. 2.1. In the production of packs made of (thin) cardboard such as cigarette packs, complex folding processes may cause problems when blank portions are moved to the proper pack position, especially when blank portions are "too long" for the folding process.      To remove this problem, the respective blank portion is, during the folding process, temporarily deformed in a way which shortens its effective length, especially curved in an arched manner. 2.2. In the production of hinge lid packs having a collar (11) attached to a front wall (12) thereof in a single piece, this blank portion is, while being folded from an upright to a horizontal position, temporarily curved by a folding leaver (58) applying pressure until the blank portion reaches the horizontal folding position.

Granted: 1997-10-28
Abstract: A composition for removing organic contaminants, such a flux residues, from a solid substrate comprises: (a) hydrogen peroxide in the amount of about 3 to 5 percent by weight of the composition; (b) an alkaline compound in sufficient amount to provide a pH of at least 10.5 in the composition; (c) about 0.1 to 0.3 percent by weight of a chosen wetting agent which is unreactive with the hydrogen peroxide and the alkaline compound; and (d) purified water as the balance of the composition.  Optionally, the composition may further comprise about 0.5 to 2.0 percent by weight of a chosen metal protective agent.  The solid substrate having organic contaminants thereon is exposed to the above-noted composition whereby the organic contaminants are removed from the substrate and are converted into non-toxic and non-hazardous products.  Thus, negative environmental impact is avoided by the present process. In an alternative embodiment, the organic contaminant removal is further enhanced by exposing the composition and the organic contaminants on the substrate to ultraviolet radiation.

Abstract: A method for preparing an engine block casting having integral cylinder bore liners (10). A barrel slab core (14) includes barrel cores (18).   Bore liners (10) surround the barrel cores (18) and are fixed in relation to the barrel slab core (14). A cylinder block mold core package (22) is assembled from the barrel slab core (14), and other cores (24, 26, 28). The liners (10) are heated while they are within the cylinder block mold core package (22) by induction heating. Access holes (30) are defined within the barrel slab core (14), each access hole (30) communicating with the interior of one barrel core (18). A heater (82) is inserted through each access hole (30). Thermal energy is thus transferred across the barrel core (18) to the cylinder bore liner (10) to assure optimum integrity of bonding between a solidified cylinder block casting and the cylinder bore liners (10). The heaters (32) are then retracted before adding the molten metal.
