Patent CA-2071768-C (CA)
Inventor: KAPLAN VLADIMIR
IPC: F24F3/14
Filed: 1992-06-22
Granted: 1994-10-18
Abstract: The present invention describes a method and apparatus for conditioning air utilizing a desiccant based air conditioning system  requiring  substantially  less  regeneration  energy  than typical  systems.     This  regeneration  energy  reduction  is accomplished through the use of two separate desiccant devices and an indirect evaporative cooler having both a wet and dry side for air flow-through.  The first desiccant device regeneration air is first passed through the wet side of the indirect evaporative cooler wherein it is humidified and heated.   This air is then dehumidified by passing through the second desiccant device which operates at a high moisture content.  This results in a substantial amount of moisture being adsorbed from the first regeneration air stream causing a substantial air temperature increase and thereby, reducing the auxiliary heat required.  The second desiccant device may be regenerated with ambient air.

Filed: 1992-07-22
Granted: 1996-10-22
Abstract: A container for packaging vials containing diagnostic specimens, or the like, which are to be mailed or transported. The container includes an open-topped plastic cylinder with an integral bottom wall having an upper section of the sidewall which is of a reduced diameter and includes opposed outwardly projecting lugs for engaging complementary slots in a cylindrical cap for the container. The upper section of the sidewall further includes a radial groove which accommodates an elastic O-ring for providing a leak-proof seal for the container. The cap slides over the upper section of the sidewall and sealingly engages the O-ring to provide a leak-proof seal. The container is further provided with an absorptive insert which is die-cut to accommodate up to three vials. The advantage of the container is that an easily manufactured, inexpensive readily packed transport container is provided which is capable of passing the drop, puncture and leakage test set forth by the UN Committee of Experts on the Transportation of Dangerous Goods.

Abstract: A biodegradable plastic composition, which may be in the form of a molded body, includes gelatinized starch and a biodegradable, aliphatic polyester resin having a melting point of 45-130 °C. The plastic is produced by kneading a blend containing a starchy substance selected from non-gelatinized, granular starch and gelatinized starch and the aliphatic polyester resin at a temperature higher than the melting point of the aliphatic polyester in the presence of water in an amount of 1-45 % based on the weight of the starchy substance.
Patent CA-2082512-C (CA)
Title: Tipping paper and cigarette using the same
Inventor: MURAMATSU MOTOHIKO
IPC: A24D1/02
Filed: 1992-03-09
Granted: 1996-11-12
Abstract: The vented filter cigarette is produced by combin-ing a filter having a highly air-permeable circum-ferential surface and a tipping paper having a plurality of pores.  The tipping paper has an embossment in the area of the pores formed therein.  The embossment serves to create a slight gap between the tipping paper and the circumferential surface of the filter, by which the tightness therebetween is loosened.  Thus, the filter ventilation is increased, and the variation in the degree of the ventilation can be reduced.

Title: Fire-retardant compositions
Inventor: CHAPLIN DOMINIC
IPC: C08K3/24
Filed: 1991-07-29
Granted: 2002-02-12
Abstract: This invention relates to fire-retardant polymer compositions, and preferably, but not exclusively, to fire-retardant polya-mide compositions. It has now been found that the combination of a zinc borate and a divalent metal stannate, particularly zinc stannate, in halogen-containing polymeric compositions provides an increased fire-retardant effect, which is greater than that ex-pected from the use of either zinc borate or the stannate alone. The combination also suppresses smoke production. Preferably the stannate is zinc stannate.

Granted: 1998-06-30
Abstract: Dans l'exécution de travaux d'excavation ou autres travaux du genre à l'aide d'excavatrices et de chargeuses, il devient de plus en plus courant d'utiliser différents équipements à commande hydraulique. Il est souvent nécessaire de changer d'équipement plusieurs fois au cours d'une journée de travail, ce qui oblige le conducteur à intervenir manuellement pour accoupler et désaccoupler les boyaux hydrauliques, ce qui exige beaucoup de temps et comporte le risque de pertes d'huile qui vont généralement souiller les vêtements du travailleur, les outils et le sol environnant. Les boyaux hydrauliques qui pendent librement des équipements enlevés sont facilement endommagés, et des particules étrangères et contaminantes peuvent s'introduire dans les accessoires non protégés. Dans le but d'assurer une meilleure protection et pour simplifier la pose des raccords de boyaux hydrauliques (8, 9) sur les différents équipements à fonctions hydrauliques quand on utilise des équipements qui s'accouplent par dispositif de couplage rapide (1) à une excavatrice, une rétrocaveuse ou autre machine du genre, les raccords ont été placés en un endroit protégé dans le dispositif de couplage rapide (1) lui-même et l'accouplement est arrangé de manière que, lorsque la partie mobile (6) du dispositif de couplage rapide se déplace dans le sens d'accouplement ou de désaccouplement de l'équipement, les raccords hydrauliques qui alimentent le mouvement de l'équipement sont accouplés ou désaccouplés en même temps.

Abstract: The plug-in socket joint secured against sliding movement is intended for socket pipes manufactured by centrifugal casting, in which the spigot end of one pipe may be inserted with radial play into the socket end of the other pipe. In this joint, a sealing ring and a clamping ring structurally separate therefrom are arranged, said clamping ring being composed of a plurality of clamping segments spaced from one another in peripheral direction. The latter have a spherical outer shell surface, are connected to each other in peripheral direction by means of a moulded-on intermediate layer of rubber or similar and each have a toothing on their inner surface. A holding part, which may be fixed in the area of the socket face end and supporting same, is formed on the clamping ring and comprises a connecting section extending to the clamping ring and tapering approximately conically, and may be expanded together with the clamping ring in dependence on the outer dimensions of the spigot end to be inserted and may thus be extended in axial direction. To prevent the toothing of the clamping segments from corroding as a result of penetrating moisture and oxygen, the connecting section is provided in its area extending from the clamping ring with the clamping segments to the holding part with at least one ring-shaped sealing edge protruding radially inwards and elastically enclosing the spigot end of the inserted pipe.

Abstract: An arrangement for reducing the possibility of switching telephone users to another preferred carrier without the intent of the telephone user.  When a record has been made in a data base indicating a change of preferred carrier, the telephone user is provided with an announcement indicating the change when the user makes a toll call.  In accordance with one embodiment of the invention the user simply is informed and if the user wants to undo the change the user contacts the local carrier.  In accordance with another embodiment the user is provided with a validation code and must enter the validation code in order to effect the change of carriers.  In accordance with another embodiment the user is provided with a number of options including the keying of a request to effect the change of carrier, or cancel the change of carrier.  Advantageously, users are informed of a change of carrier before they make any calls using the new carrier and before they receive any telephone bills identifying the change.
