Patent CA-2249055-A1 (CA)
Inventor: DURBIN MARTIN J
IPC: B60R16/03
Filed: 1998-09-29
Abstract: A time-division multiplexing system includes a control unit and multiple I/O units. The control unit generates timing signals that select one of the I/O units to be enabled at any time, and the timing signals include clock signals that index selected channels within the enabled I/O unit. The control unit stores both Boolean logical relationships among the channels of the multiplex system and functional names for the channels of the multiplex system in a reprogrammable memory. The control unit can be programmed with a programming system that uses a graphical user interface to make the programming operation simple and reliable.
Patent CA-2249731-A1 (CA)
Title: Audio signal processor with pitch and effect control
Inventor: IWAMOTO KAZUHIDE
IPC: G10H1/36
Filed: 1998-10-29
Abstract: An audio processing apparatus is constructed for generating an auxiliary audio signal based on an original audio signal and mixing the auxiliary audio signal to the original audio signal. In the apparatus, a control section designates a pitch of the auxiliary audio signal. A processing section processes the original audio signal under control of the control section to generate the auxiliary audio signal having the designated pitch, and applies a first effect to the generated auxiliary audio signal. An effector section applies a second effect different from the first effect to the original audio signal. An output section outputs the original audio signal applied with the second effect concurrently with the auxiliary audio signal applied with the first effect. The control section may control the processing section to alter the first effect dependently on a difference between a pitch of the original audio signal and the designated pitch of the auxiliary audio signal.

Title: Hydraulic pump jack drive system for reciprocating an oil well pump rod
Inventor: SCHULTZ GLENN
IPC: F04B47/04
Filed: 1998-05-27
Abstract: A hydraulic pump jack drive system (1) for reciprocating an oil well pump rod (6). The drive system comprises at least one hydraulic well head cylinder (2), a reversible flow hydraulic pump (7), and a master cylinder (8). The master cylinder has a free floating master piston (11) and at least one fixed bulkhead. The master cylinder also has a working fluid chamber (16) hydraulically connected to the hydraulic well head cylinder and at leat two master piston drive chambers (17, 18) hydraulicallly connected to the hydraulic pump. The hydraulic well head cylinder and the working fluid chamber are filled with a working fluid and define a working fluid system while the master piston drive chambers and the hydraulic pump are filled with hydraulic fluid and define a hydraulic drive system. Reversing the flow of the hydraulic pump causes the master piston drive chambers to be pressurized and de-pressurized on an alternating basis to reciprocally move the master piston within the master cylinder. The reciprocating master piston causes an alternating pressurizing and de-pressurizing of the working fluid chamber and the well head cylinder thereby causing the pump rod to reciprocate within the oil well.

Patent CA-2257597-A1 (CA)
Inventor: KLOFTA THOMAS JAMES
IPC: A61K8/97
Filed: 1997-05-30
Abstract: A lotion composition for killing such viruses as rhinovirus and influenza in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 2 to about 20 %  by weight, and tissue paper treated with such lotion compositions are disclosed. The anti-viral action of the lotion is due to the addition of an organic acid such as citric acid or a mixture of adipic acid, glutaric acid, and succinic acids. The solubilization of the organic acids within the lotion matrix and with the infected mucus is aided by the addition of such hydrophilic solvents as propylene glycol and polyethylene glycols. The lubricious lotions also contain a plastic or fluid emollient such as petrolatum, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emollient on the surface of the tissue paper web and optionally a non-ionic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided. The anhydrous nature of the lotions also aids in the maintenance of such physical properties as tensile and caliper.

Title: Power supply apparatus and method for mobile communication terminal
Inventor: PARK JAE-SUN
IPC: H04M1/73
Filed: 1999-03-05
Abstract: A compact power supply apparatus is favorable for a reduction in size of a mobile communication terminal having a transmitter and baseband signal processor, a transmitter and a power amplifier. The power supply apparatus includes a DC/DC converter for converting a DC voltage from a battery. In a reception mode of the mobile communication terminal, the power supply apparatus regulates the DC voltage converted by the DC/DC converter and supplies the regulated DC voltage to the receiver and baseband signal processor. In a transmission mode, the power supply apparatus converts the DC voltage converted by the DC/DC converter to a DC voltage corresponding to a transmission AGC (Automatic Gain Control) voltage determined depending on a transmission power and supplies the converted DC voltage to the receiver and baseband signal processor, the transmitter and the power amplifier. Since the power supply apparatus uses a single DC/DC converter and adaptively varies the output voltage of the DC/DC converter according to the transmission power in the transmission mode, it is favorable for a reduction in size of the mobile communication terminal and for a reduction in power loss of the voltage regulators and the power amplifier, thereby maximizing the power efficiency and extending the battery life.

IPC: B65B67/12
Filed: 1999-05-28
Abstract: L'appareil de support et de manutention de sacs de plastiques est un outil servant à faciliter l'utilisation et la manutention de sacs flexibles. Cette invention a principalement été conçue pour permettre l'ensachage, le rangement et la. distribution de sacs d'épicerie en plastique en vue de leur réutilisation. Avant d'aller plus loin dans la description abrégée de cet outil, il est nécessaire de faire la mise au point suivante pour éviter toute ambiguïté «le contenant ou sac porteur avec ou sans poignées est un sac flexible et le contenu est également composé d'un ou de plusieurs sacs flexibles et plus spécifiquement de sacs communément appelés sacs d'épicerie ». Le sac de plastique est un réceptacle qui a beaucoup de qualités mais à cause de sa légèreté et de sa grande volatilité il est plutôt difficile à manipuler et à utiliser. L'appareil de support et de manutention est un outil, fait d'une seule pièce, s'intégrant sur le pourtour à la gueule du sac porteur, les autres sacs étant ensachés par l'ouverture pratiquée en son centre. Lorsque les sacs sont ainsi ensachés, ils ne peuvent en ressortir sans intervention extérieur. Compte tenu du genre d'objets ensachés et plus spécifiquement poux les sacs de plastique, ce contenant peut être renversé ou bousculé en tout sens sans que son contenu ne soit répandu grâce à cet appareil de support et de manutention qui en bloque partiellement l'issue. Lorsqu'il sera nécessaire de retirer les sacs pour être réutilisés, ils pourront être extraits à l'unité et de façon ordonnée grâce à la cet appareil de support et de manutention. Dans une application dérivée du modèle de base, le dit appareil pourra aussi être utilisé avantageusement pour le ramassage d'ordures, de feuilles, de détritus ou d'autres matériaux. Cet appareil de support et de manutention est simple à utiliser et peu coûteux à fabriquer, il est également facile d'y installer rapidement un sac grâce à un système d'insertion original.
