Abstract: A method and article for microwave bonding of thermoplastic gipe such as that used in the distribution of natural gas. The article is a composite bonding material (CBM) having a thermoplastic matrix (14) (preferably polyethylene) which is miscible with the thermoplastic material of the pipe (20) and a plurality of microwave susceptor particles (11) dispersed throughout the matrix (14). The preferred susceptors have unproved heating properties whereby the total amount of metal oxide material in the CBM is about 1/10 of 1 % by weight. A strip or sleeve (24) is fashioned from the CBM and may be used, with or without a coupling, to join two pipes (20) or repair ruptures. The method includes positioning of the article at the pipe joint or rupture, and application of microwave energy in an amount sufficient to heat the susceptors and cause both the CBM matrix and the adjacent portion of the pipe to melt and flow together, thereby producing a fusion bond.

Abstract: A buffer/brake system is provided for carriers used in an automated assembly system.  The rear ends of the carriers are equipped with a flexible ring that is compressed when the queued carrier is struck by an oncoming carrier.  Compression of the flexible ring engages the sidewalls of the track support that accommodates the conveyor and the frictional engagement of the ring against the sidewalls of the track support act as a brake for the queued carrier.  The ring also acts to absorb the shock resulting from the collision between the queued carrier and the oncoming carrier.  The buffer/brake system is fully incorporated in and fixedly attached to the carrier and is not placed on the conveyor separately.

Filed: 1994-09-13
Granted: 1999-03-09
Abstract: Extra printing is made possible during a set of ordinary processing operations such as film development and printing.  A film is developed and dried while being fed by a leader attached thereto.  After cutting the leader from the film, it is fed to the printing unit to print the images on the film onto photographic paper.  A plurality of film stocking units are provided in a path from the film drying unit to the printing unit.  Each stocking unit can selectively stock a single film or leave it pass without stocking.  The second film stocking unit can move laterally to change the film track.  If a film requiring a long exposure time is present in the printing unit, the subsequent films that have been developed and dried can be stocked in the other film stocking units.  Thus, continuous film developing operations are not interrupted.

Title: Process for preparing ammonium zeolites of low alkali metal content
Inventor: COOPER DAVID A
IPC: B01J37/30
Filed: 1994-07-20
Granted: 2004-12-14
Abstract: Ammonium zeolites of extremely low alkali metal content are prepared by a process of potassium ion exchange followed by ammonium ion exchange. Zeolite X or zeolite Y that contain a significant amount of sodium are contacted with a potassium salt solution under conditions that provide a substantial exchange of potassium for sodium. The potassium enriched zeolite is then contacted with an ammonium salt solution so that the ammonium ion replaces the sodium and potassium ions. The resulting ammonium zeolite X or Y contains considerably less than 1 % alkali metal calculated as Na2O.

Abstract: A vacuum generating device, such as a wet/dry vacuum, is attached to a faucet by an attachment member. The attachment member includes a faucet connector, for connecting to the faucet, and a vacuum connector, for connecting to the vacuum generating device. The faucet connector and vacuum connector are fluidly connected by a conduit. The method for draining plumbing lines includes the step of shutting off the external supply of water to the plumbing lines. The vacuum generating device is then connected to a first faucet, and the valve to the first faucet is opened. The vacuum generating device is then activated and the valves to the remaining faucets are opened in order to create a pressure differential in the plumbing lines. The pressure differential causes water in the lines to flow into the vacuum generating device.

Abstract: A portable device as disclosed for threshing grain to obtain a sample to be tested, for example, for its moisture content, disease, and protein content.  The grain sampling device includes a housing with a handle enabling the device to be carried, an inlet for sampled grain, a chaff outlet and a collection drawer for the threshed grain kernels. Grain entering the inlet first passes through a declustering device consisting of a first group of stationary, transversely disposed pins and a second plurality of transversely disposed pins that are carried on a rotating first gear wheel. The threshing function is performed between a vertically disposed, stationary surface having a layer of resilient, frictional material, and a second gear wheel disposed in substantially parallel, spaced relation to the stationary surface, and which includes a layer of resilient, frictional material in disk form that defines a movable threshing surface. The space between the two surfaces is adjustable and chosen as a function of the type of grain to be threshed. The threshed grain sample falls into a set of transversely disposed, angular vanes that are continuously reciprocated or shaken to facilitate sifting of the chaff from the grain kernels. A blower emanates a steam of air that passes from below the angular vanes on one side angularly through to the top of the vanes and toward the chaff outlet, carrying the chaff with it for discharge. The grain kernels are of sufficient density to fall through the angular vanes into the collection drawer. A sensor can be disposed in the drawer to determine the moisture content or other parameter of the grain sample.

Granted: 2004-08-17
Abstract: An apparatus and method for a passively Q-switched microlaser (10) for producing high-peak-power pulses of light of extremely short duration are disclosed. The apparatus comprises a gain medium (12) and saturable absorber (14) disposed within a laser cavity (16, 18). When the cavity (16, 18) is pumped, the saturable absorber (14) prevents the onset of lasing until the inversion density within the cavity (16, 18) reaches a critical value. The length of the cavity (16, 18), the material parameters, and the reflectivities of the mirrors (16, 18) are selected such that pulses of duration less than about 1 ns and of peak power in excess of about 10 kW are obtained. The invention has application in high-precision optical radar, nonlinear optics, micromachining, microsurgery, robotic vision, and other technologies requiring high-peak-power laser pulses of extremely short duration.

Abstract: Un procédé pour placer une image couleur dans une structure de glace nécessite un support en matériau approprié à une méthode d'impression à quatre couleurs (CMYK), qui conserve généralement sa forme quand il est exposé à l'eau ou à une solution aqueuse, et qui est perméable à l'air. Un décalque est produit par impression de l'image sur le support au moyen de la méthode d'impression à quatre couleurs. On place le décalque sur une surface de la structure de glace et on le recouvre d'eau qui, une fois gelée, scelle le décalque et l'image qui s'y trouve dans la structure de glace. Le support devrait devenir transparent ou se dissoudre une fois scellé dans la structure de glace. Le procédé convient aux patinoires de hockey, aux pistes de curling, aux sculptures sur glace décoratives, etc.
