Title: Holo-information code of chinese characters
Inventor: DU BINGCHAN
IPC: G06F17/22
Filed: 1990-09-26
Abstract: ABSTRACT     The present invention relates to the coding of Chinese characters and more specifically, to the Holo-Information code of Chinese characters.  The said Holo-Information code is based on the radicals and the order of strokes of Chinese characters, wherein the radicals are classified, and grouped together according to the order of their first phonetic letter in the phonetic alphabet or according to their number of strokes, and finally, Chinese characters are encoded according to the representative codes of the radicals into which Chinese characters are to be broken up.  Without resorting to any pity formulas, the invention uses 100 radicals which first grade pupils can learn to read and which are the most powerful in forming characters.  The said radicals, into which Chinese characters are to be broken up according to the order of strokes in calligraphy (handwriting), are arranged according to the order of the first phonetic letter of Chinese characters' phonetic transcriptions in the phonetic alphabet or the number of strokes, thereby two Tables of 100 radicals-Holo-Information Code I and Holo-Information Code II are formed to meet the different needs of users.  This code features universality, low cost, fewer number of key striking, low repetition code rate, wide fields of potential applications, and has the advantage of being able to be operated on general-purpose machines.
Patent CA-2027766-A1 (CA)
IPC: H04Q1/453
Filed: 1990-10-16
Abstract: A multi-frequency signal receiver, and in particular a push-button signal receiver, is provided having a detector circuit and an amplitude variation supervisory circuit.  The detector circuit has a group of band pass filters, each having a pass band corresponding to each elemental signal in the multi-frequency signal.  The detector circuit also has a logic circuit for receiving each output from the band pass filters and outputting detected data of the multi-frequency signal.  The amplitude variation supervisory circuit monitors the amplitude of an input signal for a predetermined duration and detects and holds the maximum value of the monitored amplitude.  Then, the amplitude variation supervisory circuit detects when the amplitude of the input signal exceeds the maximum amplitude value to determine if the input signal is not the multi-frequency signal.

Title: Identifying earth stresses in acoustic well logging
Inventor: MEDLIN WILLIAM L
IPC: E21B49/00
Filed: 1991-01-16
Abstract: An acoustic logging tool traverses a fluid-filled cased well with a monopole acoustic energy source.  Pressure waves in the well fluid by the source generate symmetric tube waves in the well casing immediately adjacent the source.  At least one spaced-apart receiver detects these tube waves after they have traveled directly to the receiver through the well casing. Asymmetry imparted to said tube waves as they travel along the well casing by the maximum and minimum earth stresses behind the well casing are identified and used to predict the azimuthal direction of subsequent hydraulic fractures.

Patent CA-2036788-A1 (CA)
Inventor: KOENIG ROBERT H
IPC: H04B17/20
Filed: 1991-02-21
Abstract: A clock-driven pulse source is used to apply repetitive short pulses to the squelch control connection point of the squelch circuitry of a radio receiver to deactivate momentarily the squelch circuitry at regular intervals. This provides periodic noise bursts of "de-squelch" pulses on an otherwise silent radio in order to inform the radio operator that the radio is live and that the volume is adequate. A light may also be connected to the system to provide a second, visual, indicator of the operational status of the radio.    This radio receiver operational checking system may also be utilized where there are two or more radios in use by providing an additional clock-driven pulse source for each radio in use. The system may be arranged so that the status of individual radios may be quickly ascertained by sound and/or by light indicators.

Patent CA-2040445-A1 (CA)
Title: Motion display
Inventor: GIBEAULT THOMAS A
IPC: G09F11/02
Filed: 1991-04-16
Abstract: ABSTRACT            This invention is a MOTION DISPLAY to be used in advertising or promoting products or ideas. It has an unspecified quantity of triangular columns with equal length sides that rotate about their centres. Pictures are placed on these columns and as the columns rotate the picture changes. This allows the advertiser to promote three products or ideas in the same space that it would normally take to do one. The triangular columns are held in a rectangular housing and are supported at both ends with locating plates.          The locating plates or end supports act as the supports for the triangular columns, the triangular column locators and a means of rotating the columns.The columns are rotated in 120 degree intervals with a pause between each movement to give the viewer time to read or look at the picture.  The pictures are printed on a self adhesive material with a protective backing. An alternative to self adhesive material could be double sides tape or printing the pictures directly on the triangular columns. The protective backing is removed and the triangular columns are placed on the back of the picture. After all the columns are placed on the picture, the solid picture is separated into individual segments by cutting the picture with a sharp knife (razor) in between each column. This process is repeated on all three pictures. The columns are then installed into the frame. There are no special tools or processes required for this operation other than a razor blade. 1 of 5

Patent CA-2049502-A1 (CA)
Inventor: WEBER JAMES L
IPC: F04C11/00
Filed: 1991-08-19
Abstract: ABSTRACT A progressive cavity pump is used as part of the production string in an oil well. A pump stator is coupled to the production tubing string, while the rotor is driven by a sucker rod. To ensure proper placement of the rotor in the stator, the rotor is driven by a drive shaft with two universal joints with the upper end of the drive shaft held in position by a thrust bearing on the drive shaft and engaging a bearing seat connected to the production tubing. This ensures proper vertical placement of rotor in the stator. It also prevents eccentric motion of the upper end of the drive shaft, so that the sucker rod is no longer subject to whipping action that may damage the production tubing and the sucker rod string.

Title: Apparatus for comminuting solid waste
Inventor: FLAMENT GREGORY J
IPC: B02C18/18
Filed: 1991-09-10
Abstract: Apparatus for crushing, grinding and shredding solid waste material in which two interacting stacks of cutting and shredding elements are positioned on two substantially parallel shafts and mounted transversely with respect to the directions of waste material fed into the apparatus. Cutting members on one stack interact with cutting members on the other stack. In each stack adjacent cutting members are spaced from each other by a spacer. The spacers in the apparatus differ from those used in prior comminutors of this type in that they also have cutter elements on their periphery and thereby serve as cutters or shredders as well as spacers. This double function of the spacers increases the efficiency of the comminuting apparatus.      Most importantly there are cutting edges from the bottom to the top of each stack so that there are no intermediate elements on which strings or wires can be wrapped without encountering a cutting edge. While this is important in the shredding of relatively soft or easily shredded material, this is even more important in the comminuting of tires which have been reinforced with nylon cord or steel wire which have a tendency to wind around sections not having cutting edges. The process of effecting the difficult task of comminuting automobile and truck tires is also described.
