IPC: G07F11/24
Filed: 2000-08-11
Abstract: A cigarette package vending machine for selectively dispensing cigarette packages on actuation by a user includes at least one cigarette package storage and dispensing container. The container includes a storage region for storing a plurality of cigarette packages, a holding region communicating with a storage region to receive the first cigarette package from the plurality in the storage region and an output region communicating with the holding region to receive the first cigarette package from the holding region for dispensing the first cigarette package from the output region to the user. A dispenser is provided which is moveable between a rest position and an open position. The dispenser holds the first cigarette package in the holding region when the dispenser is in the rest position on actuation by a user the dispenser first moves to its open position from its rest position to cause the first cigarette package to move from the holding region to the output region. Simultaneously, the dispenser moves behind the second cigarette package of the plurality. The dispenser then moves from its open position to its rest position to dispense the first cigarette package from the output region to the user and simultaneously move a second cigarette package of the plurality from the storage region to the holding region.

Title: Method for developing answer-options to issue-questions relating to child-development
Inventor: NOCERA TINA M
IPC: G09B7/04
Filed: 1999-11-19
Abstract: Information concerning child development is developed and stored in first and second data sets containing topics and issue-questions related thereto. The information is accessed from these data sets by selectively combining an issue-question with at least one topic to produce a primary information product. A program means associated with the data sets modifies the primary information product by imposing thereon a plurality of answer-options to the selected issue-question. Each of the answer-options comprises at least one expert opinion and one parent-expert opinion, stored in third and fourth data sets. The imposition of answer-options on the information product produces a polycentric information product, which is readily communicated by oral, written or electronic means. Advantageously, the method provides to a parent, grandparent, child, teacher, nurse, caregiver, baby-sitter, or other user or viewer, an information product that is directed specifically to the concerns of that user.

Title: Ear marks for livestock registration, printing method for ear marks, and identification method using the ear marks
Inventor: MIYAWAKI YUTAKA
IPC: A01K11/00
Filed: 1999-12-09
Abstract: Conventionally, the last some digits of the Animal Registration Number printed on ear tag for identifying an individual animal in a wide area like a nation are simply enlarged for farm use. However, the simply enlarged farm use number is not a desirable number for the farm to use and is inconvenient for the farm to control animals on the farm. The present invention provides the improvement of making the ear tag, containing an Animal Registration Number CN controlled by the specific management department consisting of codes including numerals, letters, or barcodes, to be used by attaching it to an ear of an animal, in order to identify an individual animal. The Animal Registration Number CN having multiple digits prepared at the specific management department is printed at least on one of the sides of the ear tag. Some part of the Animal Registration Number CN is enlarged and printed on the ear tag as a farm use number FN in accordance with a request from an individual farm by using a minimum number of digits. The enlarged farm use number FN is generated by selecting some digits from the Animal Registration Number CN and is printed on the same or a different side of the ear tag where the Animal Registration Number is printed, so that the farm use number can be effectively created from the Animal Registration Number CN.

Patent CA-2326286-A1 (CA)
Inventor: ROTTENKOLBER HANS
IPC: G01B11/16
Filed: 2000-11-20
Abstract: With a method for determining shape changes of toroidal test objects, preferably of pneumatic tires, the test object is illuminated with coherent light. Radiation reflected by the test object during two deformation conditions of the test object is divided in an interferometer into two partial rays, which are offset from one another, the phase of one partial ray being displaced in phase steps compared to the other partial ray. The two partial rays are depicted on an image sensor system with the help of optical imaging components, and the signals that are generated from depiction on the image sensor system are digitized. The digitized signals of the phase steps of both deformation conditions of the test objects are subsequently processed to a modulo-2pi image in an image processing system. In order to be able to determine shape changes on toroidal test objects in a single test cycle with little or no interference, the test object is illuminated in a coaxial annular manner, and a partial ray is shifted on an orbit relative to the other partial ray in order to offset the partial rays from one another. The modulo-2pi image is directly filtered optically, and the filtered modulo-2pi image is processed in such a way that a deformation value is determined, which is compared to a specified threshold value.

Title: Improvements in or relating to separation processes
Inventor: LOVHAUG DAGFINN
IPC: B03D1/14
Filed: 1999-04-28
Abstract: Separation of target material from a liquid sample is achieved by coupling the target to targetable encapsulated gas microbubbles, allowing the microbubbles and coupled target to float to the surface of the sample to form a floating microbubble/target layer, and separating this layer from the sample. In a positive separation process the microbubbles are then removed from the target, e.g. by bursting. In a negative separation process target-free sample material is recovered following separation of the floating layer. The method may also be used diagnostically to detect the presence of a disease marker in a sample. Novel separation apparatus is also described.

Inventor: ANDERSON DAVID L
IPC: F16K31/06
Filed: 2001-04-24
Abstract: Method and apparatus are described for a variable force solenoid for controlling the flow of a fluid in a housing having a bore for receiving the fluid flow, at least one port for exhausting the fluid flow, and a seat extending between the port and the bore. The solenoid includes a valve member disposed in the housing. In a closed position, the valve member is engaged with the seat, preventing fluid flow from the bare to the port. In an open position, the valve member is not engaged with the seat, allowing fluid flow from the bore to the port. A subassembly is disposed in the housing and surrounds a portion of the valve member for moving the valve member to its closed position. The subassembly has a movable armature for engaging the valve member, an annular member for attracting the armature, and a gap defined between the armature and the annular member. The gap is maintained by engagement of the armature by the valve member. A coil is disposed in the housing radially outward from the subassembly. Reception of electric current by the coil produces magnetic flux, thereby attracting the armature to the annular member, and thus moving the valve member to the closed position.

Abstract: A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps, the liquid in the return line may be cooled to a temperature at which it will not flash during handling. Recirculation loops may be established associated with one or all of the slurry pumps to facilitate startup. A static flow splitter may be provided to split the flow from the last pump to two or more digesters.

Abstract: A passenger detection system is provided. The passenger detection system utilizes an oscillation circuit (10) that causes an antenna electrode (E1) to emit an electric field that is disrupted by the electrical characteristics of an object placed on the seat (1).
