Filed: 1991-06-28
Abstract: A dental composition, such as a paste or gel dentifrice containing triclosan, as an antibacterial agent which acts to decrease plaque on the teeth, and polyphosphate for anti-tartar actions, is packaged in a finger actuatable pump-type plastic dispensing container which is made of or includes a solid poly-meric material, such as a polyfluoroethylene, which is compatible with triclosan, so that excessive loss of its anti-plaque activity on storage is avoided, which losses have been noted when various other plastics have been employed as dispensing container component materials. Alternatively, others of such plastics may be employed for dispensing container parts when a stabilizer, such as a terpene, e.g., limonene, is present in the dentifrice.      The dentifrice preferably also contains a tooth hardening propo-tion of a source of fluoride ions, a stabilizing proportion (in conjunction with the fluoride source) for the polyphosphate, of a polyvinyl methyl ether-maleic anhydride copolymer, and normal dentifrice adjuvants.
Patent CA-2048782-A1 (CA)
Inventor: KING KEVIN F
IPC: A61B6/03
Filed: 1991-08-08
Abstract: 15CT03549 An x-ray CT system has a detector which revolves about the object being imaged to acquire attenuation data from many different angles through a range of at least 180.degree.. The response of the detector has a time lag which as the detector revolves tends to blur the attenuation data. The acquired data is compensated for the resolution degradation by convolving the data with a function that is the inverse of a response function of the detector. An image can be reconstructed from this compensated data. However, this compensation process tends to reintroduce noise that was reduced by the blurring. As a result, a modified version of the detector response function is applied to the compensated data to reduce the noise without degrading the image resolution to an unacceptable level.

Title: Method of and apparatus for automatically wrapping cover material about steering wheel
Inventor: ITAGAKI TOSHIO
IPC: B62D65/00
Filed: 1991-10-11
Abstract: In an apparatus for automatically wrapping a cover material about a steering wheel of a vehicle, a support arrangement is provided for supporting the steering wheel covered with the cover material, in a first plane extending perpendicularly to an axis of the steering wheel. A clamp arrangement clamps an annular strip body of the cover material to an outer peripheral section of the steering wheel supported by the support arrangement. A wiper arrangement urges one of a pair of side skirts extending respectively from side edges of the annular strip body, against an inner peripheral section of the steering wheel.      In a method, the steering wheel is covered with the cover material such that free edges of the side skirts can be abutted against each other at the inner peripheral section of the steering wheel. One of the pair of side skirts is adhered to the steering wheel while the one side skirt of the cover material is wrapped about the steering wheel from the free edge of the one side skirt to a location adjacent to the recesses. An urging tool having an urging surface following a concave surface of each of the recesses in the steering wheel is used to urge each of non-adhering portions of the other side skirt of the cover material against a corresponding one of the recesses along an urging direction, thereby adhering the non-adhering portion to the recess.

Abstract: A VLSI ARCHITECTURE FOR THE COMPUTATION OF RUNNING DISCRETE COSINE AND SINE TRANSFORMS          N. Rama Murthy and M.N.S. Swamy, Fellow IEEE Centre for Signal Processing and CommUNications Department of Electrical and Computer Engineering Concordia University 1455 de Maisonneuve Blvd. W.   Montreal, Quebec H3G lM8 ABSTRACT Despite the fact that several algorithms are available for the reduction of computation, the computation of some of the orthogonal transforms is still a computationally intensive taslc especially when one has to perform the computation in real-time. This problem is all the more significant in the transform (frequency) domain implementation of Least Mean Square (LMS) adaptive filters where a new set of transform coefficients of a block of sampleshave to be computed everytime the block gets updated with the arrival of a new sample(s). In this invention, we give an algorithm for computing updated running transform coefficients for Discrete Cosine Transform-II (DCT-II), Discrete Sine Transform-II (DST-II), Discrete Cosine Transform-IV (DCT-IV), and Discrete Sine Transform-IV (DST-IV) that is computationAlly attractive for real-time implementation. An architecture for the VLSI implementation of the proposed algorithms is also given.

Filed: 1991-06-04
Abstract: A fluid discharge apparatus for imparting a stream configuration to a current of fluid. The apparatus will allow a fluid dispenser, such as pump bottles or spray bottles that dispense lotions and cleaners, to provide the user with the ability to choose a spray configuration. The fluid discharge apparatus includes a nozzle (1) containing a passageway (2) having at least a receiving portion (3) with a substantially rectilinear cross-section and an issuing portion (4) with a substantially curvilinear cross-section, such that a fluid current passing through the passageway emerges therefrom in a stream configuration. The nozzle (1) may be pivotably connected to a second nozzle (7). The second nozzle (7) is adapted for incorporation into a sprayer-type fluid dispenser, and contains a second passageway (8). Pivoting of the first nozzle (1) towards, and its consequent attachment to, the second nozzle (7), brings the first and second passageways (2, 8) into sealed communication. This permits the fluid current generated by the sprayer apparatus to be dispensed as either a spray, when the first nozzle (1) is not attached to the second nozzle (7), or as a stream, when the first nozzle (1) is so attached.
