Title: Cation exchange resin preparation
Inventor: IMAI HIROMI
IPC: A61K9/16
Filed: 1999-07-30
Abstract: A cation exchange resin preparation in the dosage form of dry syrups and the like which comprises a cation exchange resin such as polystyrene calcium sulfonate and a gelleing agent such as carboxymethylcellulose sodium (CMC-Na), and may further comprises a binder such as hydroxypropyl cellulose (HPC). The preparation gelates and/or swells without disintegration for a few tens seconds to a minute or so when taken as suspensions in water or the preparation, per se. Therefore, the sandy feel in the mouth and throat, which is a problem in taking the preparation comprising a cation exchange resin alone, is reduced and the taste and easiness in oral administration are both improved. In addition, the efficacy of a cation exchange resin is never impaired through manufacturing processes

Inventor: WILSAK RICHARD A
IPC: B01J20/08
Filed: 1998-02-26
Abstract: Processes using heterogeneous adsorbents are disclosed for purification of olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a steam of olefin having from 2 to about 8 carbon atoms, containing acetylenic impurities having the same or similar carbon content, and optionally saturated hydrocarbon gases, through a particulate bed of adsorbent comprising predominantly a support material having high surface area on which is dispersed at least one metallic element.  Adsorption is carried out in an essentially dihydrogen-free atmosphere within the bed, selective and reversible adsorption and/or complexing of the contained acetylenic contaminants with the adsorbent, and thereby obtain purified effluent which contains less than a predetermined level of the acetylenic impurities. Selective and reversible adsorption and/or complexing of the contained acetylenic impurities with the adsorbent is continued until levels of acetylenic impurities in the effluent stream increase to a predetermined level. Thereafter the resulting bed of adsorbent is regenerated in the presence of a reducing gas containing dihydrogen to effect release of the contained acetylenic impurities from the adsorbent.

Title: Decoupling service creation environment from service logic execution environment
Inventor: FUNNELL PATRICIA
IPC: H04Q3/00
Filed: 1998-03-10
Abstract: A service creation environment (SCE) (10) generates generic service creation information defining a certain service. The generic service creation information is then processed by a service execution agent (14) for mapping (102) onto service creation information that is specific to the service logic execution environment (SLEE) (12) of a service control point (SCP) upon which the service is to be executed and provided. This SLEE specific service creation information is then down-loaded (104) to the service logic execution environment, and converted in a conventional manner to service execution related information. The generic service creation information comprises only a certain limited number of primitives (instructions or commands) operating on a certain limited number of service independent building blocks (SIBs). The mapping operation (102) is made from these limited primitives and service independent building blocks to SLEE specific primitives and service independent building blocks, or SLEE specific general programming language commands, or SLEE specific specification description language (SDL) commands

Patent CA-2287954-A1 (CA)
Inventor: BRUCKERT EUGENE J
IPC: H04W28/22
Filed: 1998-03-13
Abstract: In a communication system where a continuous reverse channel transmission is utilized by redundant transmission of Walsh codes, a current transmission rate is modulated onto Walsh code polarity. In particular, a remote unit operating at a particular transmission rate utilizing a continuous reverse channel transmission modulates the transmission rate by setting the polarity of each Walsh code depending upon the current or future data traffic channel rate. In communication systems where a Reference Coherent (RC) type transmission is utilized, the particular transmission rate is modulated onto the reference symbols (501-517) by setting the reference symbols (501-517) equal to a binary "1" or "0".

Title: Decorative automotive interior trim articles with cast integral light stable covering containing an invisible tear seam and process for making the same
Inventor: WILSON PHILIP S
IPC: B60R21/2165
Filed: 1998-06-09
Abstract: An article including a panel-like structure mountable in an automobile vehicle to form a part of the interior thereof and conceal a secondary restraint system, and a process for making the same are disclosed. According to this process, an outer layer is established on a first mold surface, with the exterior surface of the outer layer having an opaque visual appearance and a configuration complementary to the first mold surface. A casting composition is then rotationally casted onto an inner surface of the outer layer to create an inner layer of a predetermined thickness while restricting the gel thickness along an elongated structurally weakened tear seam. The casting composition is then fused. The outer layer and inner layer collectively define a layered composite structure, with the outer layer presenting the same opaque visual appearance to the exterior surface thereof unaffected by change in the inner layer thickness so that the structurally weakened tear seam is hidden from view. The composite structure is united with areinforcing substrate including at least one door so that the structurally weakened tear seam is in cooperative association with the door so as to fracture when the door is actuated.

Patent CA-2299301-A1 (CA)
Inventor: HENRIKSSON PAR
IPC: A01M21/04
Filed: 1996-08-15
Abstract: For many years the use of pesticides have, beside purely mechanical methods, dominated. An increasing concern has led to an increasing interest in alternative methods. The invention is based on high voltage pulses with short duration for electropermeabilizing of the cell membranes of weed seeds in the ground. The device is selective and damages only germinating weed seeds and plants early in the life cycle. The required amount of energy is small; with rectangular pulses the optimal field strength is between 100-300 kV/m with a duration of (10-100 microseconds). A transformer (2) for instance placed on a sowing machine transforms electrical or mechanical energy to high voltage pulses. The energy is for instance taken from the pulling tractor via a transmission (1) or from a local power source. The high voltage pulses are applied electrically conducting via applicators (3), two or more, with permanent relative distance to the soil around the newly sown seed in form of pulses with short duration.
