Patent CA-2119717-C (CA)
Inventor: OLIVE RAYMOND GUY
IPC: A47K10/38
Filed: 1994-03-23
Granted: 1999-04-27
Abstract: The invention provides an inexpensive unit for removable attachment to the spindle of a roll holder for a roll-type paper product such as toilet tissue of paper towelling.  The unit is formed from a flexible plastics material and includes a centre section having an arcuate bight portion and a pair of wall portions that converge from the arcuate portion and are joined together along the free edges thereof.  An arm extends laterally from each end of the joined free ends of the walls.  The unit is slid onto a spindle and when a roll of paper material is in turn slid onto the unit-carrying spindle the joined free ends of the walls will forcefully-engage the inner surface of the roll core. When a user pulls the free end of the paper material wound on the roll the unit of this invention will rotate with the roll until the laterally extending arms engage or abut the edges of the roll holder.   This signals the user that an appropriate length of material has been pulled from the roll and that that length may now be torn from the roll.  If more material is required the user continues to pull on the free end of the paper material, causing the arms to flex inwardly and to be drawn through the roll holder until they emerge, flex outwardly again and are then available to once more abut the edges of the roll holder, signalling that another revolution has been completed and that the pulled length may be torn from the roll.  The invention is particularly useful for people on a  fixed  income and  for people  that may  be physically challenged in their motor functions.

Title: Use of selected inhibitors against the formation of solid organic-based incrustations from fluid hydrocarbon mixtures
Inventor: VON TAPAVICZA STEPHAN
IPC: E21B37/06
Filed: 1992-12-22
Granted: 2004-09-14
Abstract: A method is provided herein for inhibiting the formation of solid hydrocarbon incrustations from hydrocarbon mixtures which are fluid and prone to form such incrustations. The method includes the step of contacting the hydrocarbon mixtures with an inhibitor mixture comprising esters of phosphoric acid or salts thereof and alkoxylated aliphatic alcohols, alkoxylated cycloaliphatic alcohols or alkoxylated aromatic alcohols, and fatty acid oligo-dialkanolamides. These inhibitor mixtures preferably have a surface-active character and are capable of wetting, and especially of spreading on, solid work material surfaces in the presence of the fluid hydrocarbon. These inhibitors are especially useful for the protection of pipelines, pumps, filters, tanks and metal surfaces against the formation of incrustations thereon.
Patent CA-2133380-C (CA)

Granted: 1999-05-25
Abstract: A drive system for producing agitation and spin in an automatic washing machine incorporates a transmission assembly including a plurality of interengaged transmission elements located within a transmission housing. During agitation, the transmission housing is braked and the transmission elements convert input rotary drive from a motor to oscillatory drive of an output shaft. During spin, a cam member carried by one of the transmission elements automatically shifts a stop element into engagement with the transmission housing. This maintains the transmission elements in a predetermined orientation, prevents relative rotation between each of the transmission elements and the transmission housing and causes the entire transmission assembly to rotate in unison which results in rotation of the output shaft. Since the transmission elements are maintained in the same predetermined orientation during each spin, the entire transmission assembly can be effectively counterbalanced to minimize unbalancing of the system and reduce vibrations during operation.

Granted: 2000-09-19
Abstract: In a method of detecting motion vector data indicative of motion of a partial area in an input picture from any area on a reference picture, a first distortion between a partial area constructed by fields of the input picture and a partial area constructed by fields of the reference picture is calculated as a  first evaluation value;  a position of the partial area constructed by the fields of the reference picture at which the first evaluation value becomes the minimum value is detected; a search windowon a frame of the reference picture is set on the basis of a detected position of the partial area constructed by the fields of the reference picture previously detected; and a second distortion between a partial area constructed by a frame in the set search window and a partial area con-structed by a frame of the input picture is calculated as a second evaluation value, and a position of the partial area constructed by the frame of the reference picture at which the second evaluation value becomes the minimum value is detected.  Therefore, the frame vectors can be detected on the basis of the field vector detection positions, so that the amount of calculations required to retrieve frame vectors can be reduced markedly,  without degrading the detection precision of the frame vectors.

Abstract: This tone detector which is suited for dual tone multifrequency (DTMF) digit detection, separates the pairs of tones into a low frequency and high frequency group in which the other frequency group is attenuated by filtering.  The amplitude of the low and high frequency groups serve as separate variable threshold reference signals.  Individual tones are bandpass filtered with their corresponding outputs converted into an amplitude signal.  The amplitude of the individually bandpass filtered tone signals are compared against the corresponding low or high frequency variable threshold signal for a determination of whether a tone is present. Preferably, additional validation steps are applied to the preliminary tone decisions to provide improved digit detection accuracy, especially in the presence of other signals such as speech.
