Inventor: STOCKMAN ROBERT M
IPC: H01G4/22
Filed: 1999-10-08
Abstract: A metallized film capacitor is provided with a polyurethane oil insulating fluid. The insulating fluid has a viscosity in the range of about 500 to 3000 poise at 25°C. The polyurethane oil insulating fluid is produced by reacting an organic polyisocyanate with a primary polyol selected from the group consisting of castor oil, ricinoleic acid derivatives of castor oil and mixtures thereof. The reaction may be carried out in the presence of a secondary polyol chain extender such as a hydroxy-terminated polybutadiene diol. The reaction to produce the insulating fluid is carried out under conditions wherein the ratio of NCO groups of the organic polyisocyanate to OH groups of the primary and secondary polyols, if present, is in the range of about 0.1 to 1 to about 0.6 to 1. The ratio ensures that there is no excess of unreacted NCO groups in the insulating fluid and that the reaction produces a viscous fluid, not a substantially solid elastomer.

Title: Capacity data monitor
Inventor: MAGOTO DANIEL C
IPC: B66F17/00
Filed: 1998-07-01
Abstract: A fork lift truck (100) capacity monitor or alerting device informs operators of the weight on the forks (150) and fork height and alerts operators whenever truck speed is above creep with the forks raised above a collapsed height (34) or whenever the forks are raised above a recommended height for a given load.

Title: Cryptographic token and security system
Inventor: LARAYA JOSE LUIS R
IPC: H04L9/32
Filed: 2000-01-17
Abstract: A secure internet telecommunications system for transmitting, data has a security module which is positioned between a first computer and a a network. The security module has a cryptographic logic device that encrypts and decrypts data transmitted from the first computer in accordance with known standard encrypting and decrypting protocols. The security module is actuated by the insertion of a cryptographic token bearing a user's cryptographic key information and/or other user information. This token is first enabled to make this information available to the security module. The cryptographic token is preferably a PC card, an IC card or a Smart Card having a contact sensitive graphical user interface. The token captures through the interface a template associated with a user's ideogram signature information and stores this template and other information in memory. The template is then compared with subsequent inputs of this ideogram signature information from the user and verified to enable the cryptographic token to function with the security module. The cryptographic token may have either an independent power source permitting the token to be enabled off line from the security module or alternatively relies on the power supply of the security module. The present invention has advantage in that user information is stored on a token device which must be enabled by a user and temporarily connected with the security module to permit the use of the user information.
Patent CA-2299098-A1 (CA)

IPC: G01N33/10
Filed: 2000-02-22
Abstract: A method and an apparatus are provided for estimating a quality of grains to be harvested from a grain plant in the future, during a growth period prior to the harvesting. The method comprises the step for establishing a quality conversion coefficient for estimating a specific quality of grains after the harvesting based on absorbencies relating to the specific quality of the grains obtained by irradiating light having predetermined wavelength regions on a leaf of a grain plant in growth at a predetermined time during the growth period of the grain plant and the specific quality obtained from the same grains after the harvesting, and the step for estimating the quality of the grains to be harvested in the future based on said quality conversion coefficient and absorbencies relating to said specific quality obtained from a leaf of the grain plant presently growing at the predetermined time. The measurement for estimating the quality of the grains can be carried out in an easy and simple manner during the growth of grain plants.

Title: Oxazolidine hardeners for bonding wood articles with resorcinol resins
Inventor: WU GAOMING
IPC: C08G8/26
Filed: 1998-08-14
Abstract: An improved oxazolidine-based hardener to be used with a resorcinol resin or a tannin resin as the adhesive for the bonding of wood articles. Preferably, an oxazolidine is combined with particulate silica, and the resin is combined with a base such as NaOH. The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength requirements after the glue is cured at room temperature for under 24 hours. The improved hardener composition is storage stable; it can be prepared anytime before its use and, thus, eliminate the need to prepare a hardener immediately prior to the glue use. Since it is formaldehyde-free, it eliminates the safety issues associated with handling formaldehyde or paraformaldehyde. Also, the hardener provides flexible gel time or working time. Since the resins can be cured at room temperature, heating in an oven is not needed but could be used to reduce curing time. If radio frequencies are used to cure the resins, the exposure time can be reduced.

Patent CA-2302006-A1 (CA)
Inventor: HESCH ROLF
IPC: D04H1/68
Filed: 1998-06-29
Abstract: The invention relates to a long fiber-foam composite material, in which the long fibers are bonded to form a loose but dimensionally stable structure with good recovery properties. The long fibers are only partially bonded by foam particles in the shape of nodal points. The foamed or unfoamed foam particles are applied to the structure when the latter is being formed. The unfoamed foam particles applied to the structure are foamed by reacting or reactivating the blowing agent previously applied to the bonding agent to be foamed. The expansion can freely take place without limiting the volume so that a minimal possible thickness can be obtained by complete expansion or in a predetermined volume having a predetermined thickness, for instance, by expansion in a double wall press or a mold.

Title: Notifying device and wireless communications system incorporating same
Inventor: GENNO HIROKAZU
IPC: B06B1/04
Filed: 1998-12-28
Abstract: An alerting device which has an alerting unit (2) with a built-in vibrator resonated when receiving a driving signal and a signal generating circuit (5) which supplies a driving signal to the alerting unit (2). The signal generating circuit (5) generates the driving signal Dv whose frequency varies within a certain frequency range containing the resonance frequency of the vibrator and supplies the driving signal Dv to the alerting unit (2). The variation width of the frequency of the driving signal is predetermined in accordance with the variation width of the resonance frequency which is caused by the tolerances of the factors determining the resonance frequency.  Further, the driving signal has an alternating rectangular or sinusoidal waveform and its frequency varies within a range of 1.37 - 2.98 Hz periodically. By the alerting device, a sufficient alerting effect can be obtained regardless of the variation of the resonance frequency of the vibrator.
