Patent CA-2277035-A1 (CA)
Title: Tdm/tdma distribution network
Inventor: STACEY DAVID JOHN
IPC: H04L12/70
Filed: 1998-01-16
Abstract: Communicative services are transported over a TDMA or TDM access network by packetising the services into minicells which minicells are transported within minislots created by subdivision of the TDM time slots. For low bit rate communicative services only, minislots are allocated periodically rather than in the blocks that are allocated to high bit rate services. The packetisation delay inherent within the transport layer can be significantly reduced for these low bit rate services.

Abstract: The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aesthetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90 % of the composition and contains a deodorant or antiperspirant effective amount (e.g.  about 3 to 25 %) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25 % of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent. The silicone oil comprises a mixture of a non-volatile silicone, preferably a non-volatile linear silicone, and a volatile linear silicone. It has been found that reducing the amount of non-volatile silicone in the known gel composition to a relatively low level (e.g. below about 5 %) and adding an amount of volatile linear silicone to the composition (e.g. above about 2 %, preferably above about 5 %) substantially improves the non-staining properties of the composition.

Abstract: This invention relates to a system where chemicals are to be mixed, heated and circulated for de-scaling, degreasing and passivating. The inventor has worked in marine, shipping and oil-field for nearly 35 years. He had the opportunity to attend more than one thousand four hundred ships from all over the world but, never came across any such equipment that could carry out the intended work with expected result. There have beep times when 2000 - 3000 kgs. of flaked chemical had to be mixed manually.  Normally twa ways to de-scale and degrease the boilers, heat exchanger, chemical tanks etc.  are utilized. (1) Manual and (2) Chemical. With chemical cleaning process, the cleaning period is reduced to about 20% of time required by manual cleaning but, the expected effect is still not accomplished because all the manufacturers requirements are not met with. This invention overcomes almost all the shortcomings. This has application in many fields such as marine, shipping, oil-field, refinery, chemical transportation, air-conditioning plants and power generating plants; just to name few. This will provide a very quick and effective means of cleaning with less labor, less expense and with less hazardous environment to the workers. The wastage of the unused chemicals will be reduced. The system is so simple that No special training will be required to operate and manage it.

Title: Removable vehicle seat assembly
Inventor: VANDOREN FOSTER
IPC: B60N2/015
Filed: 1998-07-07
Abstract: The present invention is a removable vehicle seat assembly for use with a motor vehicle having an interior floor structure with at least a portion thereof covered by a yieldingly deformable material. A latch and release assembly is operatively associated with a riser support structure. The latch and release assembly engages with front and rear anchor members of the interior floor structure and releasably locks in one of a range of releasably locked positions. The latch and release assembly engages with the front and rear anchor members and is releasably locked in an initial one of the range of releasably locked positions. The removable vehicle seat assembly is moved downwardly towards the interior floor structure in response to an application of a downwardly directed force thereto when the latch and release assembly is releasably locked in the initial one of the range of releasably locked positions such that the yieldingly deformable material is yieldingly compressed to a decreased thickness. The latch and release assembly moves progressively from the initial one of the range of releasably locked positions to a subsequent one of the range of releasably locked positions corresponding to the decreased thickness of the yieldingly deformable material during downward movement of the removable vehicle seat assembly. The latch and release assembly is engaged with the front and rear anchor members and releasably locked in the subsequent one of the range of releasably locked positions to thereby prevent upward movement of the removable vehicle seat assembly away from the interior floor structure and to maintain the yieldingly deformable material at the aforesaid decreased thickness.

Title: Extended piggyback dispensing device with interchangeable application guides
Inventor: CHANG PETER J
IPC: B05C17/01
Filed: 2000-02-08
Abstract: An improved piggyback dispensing feature for extended dispensing devices. The piggyback feature may be incorporated in any conventional extended dispensing device of the type having a housing with a downwardly extending handle, a trigger pivoted to the handle, an extension bracket attached forwardly of the housing, a barrel assembly attached to the extension bracket opposite the housing, a piston rod slidably supported in the housing and extension bracket and protruding into the barrel assembly. The improvement comprises an interchangeable push-disk piston mounted on the distal end of the piston rod, and a smaller barrel assembly adapted to be seated inside the other larger barrel assembly to accommodate a smaller-sized cartridge. The smaller barrel assembly piggybacks in the larger, and the push-disk piston swaps out, thereby making it possible to use one extended gun for at least two different--sized cartridges, such as the typical 1/4 gallon cartridges and 1/10th gallon cartridges. A variety of interchangeable/adjustable guide assemblies are also shown for attachment to the dispensing gun for guiding the application of a bead of caulk or adhesive along trusses, joists and other structural components. The guide assemblies include a quick- change and an adjustable guide both with opposing legs attached to a T-shaped undercarriage. In the latter case, the legs are readily adjustable by hand on-the-fly to accommodate large- width and double--trusses and joists. A quick-change detent-locking guide assembly for the above- described dispensing gun is also shown to allow a quick-change reversal to accommodate single joist, double joist, and other structural components.

Abstract: The purpose of the present invention is to provide a datagram transfer network that can operate stably by avoiding a state of congestion collapse by utilizing information derived from evaluating the impact of datagrams on the operation of the network. To achieve this objective, the results of evaluation is expressed as a preference value related to datagrams, and are inserted in the header in each datagram so that the datagrams are processed by an approach other than the methods based on arrival sequence of datagrams, when derived to the destination indicated in the header. In this approach, forwarding of datagrams is controlled by priority order derived from the preference value which reflects traffic information obtained by a traffic monitoring equipment.

Abstract: Un article absorbant caractéristique comporte une partie centrale absorbante à couches absorbantes multiples, les couches absorbantes interagissant de manière à transférer de préférence le liquide absorbé dans une couche d'imbibition haute saturation désignée. Le fait que le liquide se trouve dans cette couche d'imbibition permet d'accroître le potentiel de cette couche à déplacer le liquide par capillarité en raison du taux de saturation élevé et d'une quantité croissante de liquide disponible. On maintient ou on améliore la capacité d'absorption du système absorbant par rapport à des systèmes actuels en maintenant des taux de saturation faibles dans une deuxième couche du système absorbant lors de salissures aussi fréquentes que possible, tout en assurant des performances d'absorption optimales par un ajustement approprié des propriétés du composite. Le faible taux de saturation de cette couche permet d'assurer un volume de vide pour les salissures entrantes ainsi qu'une grande perméabilité, ce qui permet d'accroître le taux d'absorption du système absorbant dans son ensemble; mais la structure de la couche à faible taux de saturation est aussi équilibrée en vue de conférer un taux suffisamment élevé de tension capillaire pour obtenir assez de rétention de liquide afin d'empêcher des fuites.
