Title: Systeme permettant de separer debris et milieux de grenaillage
Inventor: PITTMAN JAMES
IPC: B24C9/00
Filed: 1999-05-07
Abstract: L'invention se rapporte à un système (1) conçu pour le grenaillage d'une surface, qui récupère le milieu de grenaillage utilisé ainsi que les débris et qui sépare les débris dudit milieu. Ce système comporte au moins une tuyère de grenaillage (105) pourvue d'un capuchon (100) relié à un tuyau d'aspiration (110). Il comporte également une chambre de refoulement (200) dont une entrée est reliée au capuchon par le tuyau d'aspiration, un déflecteur d'entrée (220), une zone de collecte et d'évacuation des matières solides (205) conçue pour recevoir les matières solides qui tombent du flux gazeux dans la chambre de refoulement, un déflecteur de sortie (225), une sortie (226) pour le courant gazeux et une vanne à boisseau tournant (510) destinée à l'évacuation des matières solides. Une première unité de filtrage (300) et une seconde unité de filtrage (310) sont reliées à la chambre de refoulement par l'intermédiaire d'un premier conduit (230). Un contenant (600) pour le milieu de grenaillage est relié au tuyau (120) pour l'alimentation en milieu de grenaillage, ce tuyau étant lui-même relié à la tuyère de grenaillage. Par ailleurs, une soufflante (400) provoque l'aspiration du courant gazeux, depuis la tuyère de grenaillage vers la chambre de refoulement, à travers la première unité de filtrage et la seconde unité de filtrage. Un séparateur à tamis vibrant (500), qui est disposé en position adjacente à la vanne à boisseau tournant, permet la séparation des grosses particules et du milieu de grenaillage. Un filtre à poussières et à peinture (700) est relié à la première et à la seconde unité de filtrage d'une part et à la chambre de refoulement d'autre part, de manière à filtrer les produits issus des unités de filtrage. Le filtre à poussières et à peinture utilise l'aspiration de la soufflante à partir de la chambre de refoulement pour aspirer les produits de filtrage provenant des deux unités de filtrage.

Abstract: A paperboard carrier (1, 101, 101', 301) is provided. The carrier includes a two ply top panel (11, 111'), side walls (7, 9, 107, 109, 107', 104', 207, 209, 307, 309), and a bottom panel (5, 105, 105', 205, 305). Apertures in the top (31, 33) and bottom (17) panels allow for the carrier to be applied to a set of bottles. Tabs (37, 39) are formed in the top panel to support the bottles in the carrier. The carrier is provided with many different features, including a tongue (19a, 19b, 24) which extends upwardly from the edge of the bottom panel apertures. The tongues engage the underside of the top panel to help prevent racking of the carrier relative to the bottles and to help space the top and bottom panels apart. The base of the tabs in the top panel top ply (13) define a circle greater in diameter than the top panel bottom ply (15) apertures (33), and the tabs engage the bottle at an angle of less than 45~.  The tabs surrounding the top panel aperture can be of varying lengths. End panels (316) are provided. The end panels are held substantially perpendicular to the top, bottom, and side panels by locking panels (318). The locking panels include apertures (320) which are aligned with the bottom panel apertures (317) and are sized to allow a bottle to pass therethrough, so that the bottle will hold the end panel in its position. The side panels can be of multiple plies.

Filed: 1999-05-18
Abstract: A low differential check valve is provided for a fire control system, having particular adaptability in a dry system. The check valve is maintained in its closed position by a latch which is controlled by a plunger. The plunger is activated, and moved to release the latch, upon the sensing of drop in system air pressure by a higher differential mechanism external of the check valve. The check valve may then be reset, with its clapper moved to its closed condition, without requiring internal access of the check valve to release a clapper latch.

Inventor: CHOUDHARY VIKAS
IPC: H04L7/033
Filed: 2001-06-27
Abstract: Over-sampled timing signal jitter tolerance is improved in a q-times over-sampled architecture by phase-sampling the timing signal to produce a plurality of input phase samples ~in, where ~in .epsilon. {~1,~2,...,~q). An output phase value ~out = ~in is initialized for each input sample ~in. A difference vector d i is derived for each input sample ~in, where d i = F j(n,k). F denotes a vector operation, n is the number of input samples, k is a pre-defined threshold value, and j represents a filter order value. A predefined scaling coefficient ai is applied to each difference vector d i to produce a corresponding set of scaled difference vectors a i d i. The scaled difference vectors are summed:   The output value ~out is incremented by 1 if d j > k; decremented by 1 if d j < -k; and maintained unchanged if -k <= d j <= k. Finally, the output value ~out is selected to represent the input sample ~in.

Title: Virtual waveplate and optical channel interleaver formed therewith
Inventor: DUCELLIER THOMAS
IPC: G02B5/30
Filed: 2001-07-31
Abstract: A conventional interleaver, based on a stack of waveplates, relies on the orientation and the birefringence of the waveplates to differentiate the polarizations of one set of channels from another, so that the one set of channels can be separated from the other. The present invention relates to a virtual waveplate that is used to replace a birefringent waveplate. A virtual waveplate imposes a phase delay between the extraordinary ray and the ordinary ray by separating one from the other and differentiating the actual path lengths taken thereby, before recombining them. An interleaver constructed with the virtual waveplates of the present invention can be substantially a-thermal and potentially chromatic dispersion free.

Filed: 2000-10-25
Abstract: The invention concerns an optical transmission system, wherein the energizing signals are transmitted in the form of synchronous digital hierarchy (SDH) signals or forward error correction (FEC) signals. The transmission system comprises a transmission channel, typically a supervisory channel, having a lower rate than that of the energizing signal; said channel is transmitted by over-modulation of a subcarrier. The frequency of the subcarrier is selected so as to limit demodulation errors in the subcarrier due to the energizing signal harmonics.

IPC: F16H29/00
Filed: 2000-01-06
Abstract: Flexible link drive apparatus having a housing (100) rotationally supporting an eccentric input shaft (116) and an output shaft (118). An eccentric roller assembly (216) is coupled to the eccentric input shaft, and the eccentric roller assembly comprising at least one input roller (238, 240). Additionally, a clutch member (260) is coupled to the output shaft (118). The present disclosure further relates to a flexible connection member (282) that has a fixed end coupled to the housing through a flexible connection member anchor, and a free end coupled to the housing through a biasing member (268). The input roller (238, 240) intermittently contacts the flexible connection member and rotates the clutch member and the output shaft.  The coupling of the free end of the flexible connection member to the housing by the biasing member causes a greater angle of travel for the clutch member and produces a greater output shaft rotation.

IPC: G06F9/35
Filed: 2000-03-09
Abstract: A double indirect method of accessing a block of data in a register file (81 8) is used to allow efficient implementations without the use of specialized vector processing hardware. In addition, the automatic modification of the register addressing is not tied to a single vector instruction nor to repeat  or loop instructions. Rather, the technique, termed register file indexing (RFI) (820) allows full programmer flexibility in control of the block data operational facility and provides the capability to mix non-RFI instructions  with RFI instructions. The block-data operation facility (814) is embedded i n the iVLIW manArray architecture allowing its generalized use across the instruction set architecture without specialized vector instructions or bein g limited in use only with repeat or loop instructions. The use of RFI (820) i n a processor containing multiple heterogeneous execution units (852 and 854) which operate in parallel, such as VLIW or iVLIW processors, allows for efficient pipelining of algorithms across multiple execution units (852 and 854) while minimizing the number of VLIW instructions required.
