Title: Automatic tree and/or plant waterer
Inventor: MCDOUGALL DALE
IPC: A01G27/00
Filed: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE A novel  automatic tree and/or plant waterer  is provided herein.  It is adapted to be connected to a stand which holds a tree, e.g. a Christmas tree, in an upright position.  The waterer includes a hollow base and a hollow body section.   Means are provided for locking the hollow base in a water tight sealed manner to the hollow body section.  A cover is selectively secured to the hollow body section in an airtight manner.   A water outlet is provided from the interior of the body section.  A flow controller unit is provided from the interior of the body section to the flexible hose in order to allow for easy filling and refilling of the interior of the body section.  A flexible hose is adapted to be connected between the water outlet of the hollow body section and the stand which holds the tree.   Once the flow of water is commenced, a cyclic automatic flow of water ensues.  The water will not flow unless air is allowed to enter through the tube.  Thus, when the end of the tube is submerged in water, no water can flow.

Patent CA-2056294-A1 (CA)
Inventor: WATANABE TAKAO
IPC: G10L15/193
Filed: 1991-11-27
Abstract: On carrying out connected word recognition in compliance with a regular grammar and in synchronism with successive specification of input feature vectors of the input pattern, one of an n-th word (n) of first through third occurrence (n(1) to n(3)) is selected as the n-th word of selected occurrence in an i-th period in which an n-th input feature vector is specified.  The n-th word appears as the first through the third occurrence in transition rules specified by the grammar.  In the n-th period, distances are calculated, only for the n-th word of the selected occurrence, between the input feature vector assigned to the i-th period and reference feature vectors for the n-th word.  In the i-th period, a recurrence value g(n, i, j) is calculated only for the n-th word of the selected occurrence under a boundary condition T(p, i-l) iteratively in correspondence to the reference feature vectors by using the distances calculated for the n-th word of the selected occurrence before the i-th period, where j represents each feature vector.  The recurrence value for the n-th word of nonselected occurrence is estimated by using the recurrence value for the n-th word of the selected occurrence and the boundary conditions T(p, i-l)'s for the n-th word of the selected and the nonselected occurrence.  The above-mentioned one of the n-th word of the first through the third occurrence is selected so as to have a minimum value of the T(p, i-l)'s.

Filed: 1992-01-28
Abstract: Abstract of the Disclosure A method for removing and recovering hydrocarbons contained in hydrocarbon/water mixtures.   Hydrocarbons are stripped from nonflowing hydrocarbon/water mixtures in a tank by bubbles of inert gas, such as air, introduced under pressure.  The air and hydrocarbons are vented from the tank and the water is removed from the tank when satisfactorily purified.  The material in the tank preferably is heated.  A two-tank process may be used wherein the second tank is filled while the stripping process in the first tank is taking place. The rate of flow of the inert gas is maintained at a low enough rate to allow recovery of product.          RH
