Abstract: In word games, words are usually formed across the board from left to right, and across the board from top to bottom.  Tiles are placed such that every contiguous group of tiles, when read either left to right or top to bottom, as appropriate, represents an acceptable word.  Also the values of the letters may be fixed, and scores are calculated with respect to the ordinariness or else specialness of the squares they occupy on the board.  In this invention, words are formed across the board from left to right, but the constituent letters are three squares apart; across the board from top to bottom, but the constituent letters are three squares apart; along a winding path like a stairway, with the constituent letters contiguous from one step to the next step.  The value of a letter depends on its distance from a reference point for that letter.  Scores are calculated by multiplying letter values that have a special line between them, and adding groups of multiplied letter values.  Players' access to specific tiles is controlled by keeping a recording sheet for rate of use of the letters, and of the tiles, generally.  Charts are provided to facilitate preparation of three-dimensional crossword puzzles based on this invention.

Title: Two stage pressure control valve
Inventor: STOBBS THOMAS J
IPC: F15B13/043
Filed: 1994-04-01
Abstract: A two stage pressure control valve (10) has a poppet (66) movable toward and away from a valve seat (70) to vary the cross-sectional area of a passageway from an inlet (72) to an outlet (52). The position of the poppet (66) is dependent in part on the difference in pressure between a fluid pressure at the inlet (72) which exerts a force on the poppet (66) in one axial direction and a control pressure which is produced by a fluid flow from the inlet (72) in a chamber (94) downstream from the inlet (72) and which exerts a force on the poppet (66) in the opposite axial direction. The control pressure is controlled by an electromagnetic coil (22) which can be variably energized to move an armature (30) so as to vary a variable, restriction downstream from the control pressure so as to vary the control pressure. A tube (80) extends through and forms an axial sliding seal with the poppet (66) and communicates a flow of fluid from the inlet (72) to the variable restriction and the chamber (94) is positioned adjacent to an exterior surface of the tube (80). An orifice (90) through a wall of the tube (80) communicates a lumen (92) of the tube (80) with the chamber (94).

Patent CA-2170981-A1 (CA)
Title: Embossing with reduced element height
Inventor: BROWN JOSEPH WILLIAM
IPC: D21H27/02
Filed: 1996-03-04
Abstract: High sheet count rolls of spot-embossed, soft bathroom tissue suffer from embossing patterns becoming pressed out by the high winding tension necessary to confine the size of the roll to a diameter of about 5 inches.      This size is necessary in order for such high sheet count rolls to fit within the bathroom tissue dispensers found in most households. However, by embossing the tissue between a resilient back-up roll and an engraved embossing roll having short male embossing element heights of only from about 0.005 to about 0.035 inch, the tissue sheet becomes simultaneously calendered, which lowers the sheet caliper (as measured under a compressive load). Because of the resulting lower caliper, the embossed sheet can be wound into the required roll size with less tension on the sheet, such that the embossing pattern for tissue sheets within the roll remains well defined.

Title: Hands-free communication method for a multichannel transmission system
Inventor: WALKER MICHAEL
IPC: H04M9/08
Filed: 1996-05-10
Abstract: With hands-free communication methods for stereophonic hands-free communication to transmit room acoustics, and with multichannel hands-free communication to reproduce different speaker locations at a conference table, the acoustical couplings between loudspeakers and microphones located in the room must especially be taken into consideration, in addition to the influence of ambient noise and the control of duplex communication situations. The n2 couplings take place in n-channel transmission systems.  According to the invention, for each coupling, a coupling factor (dlm) is formed from the quotient of a short-term average value of the transmitted signal (ysam) assigned to a microphone, and the short-term average value of the received signal (xsam) assigned to a loudspeaker.  With the coupling factor (dlm) weighted with the short-term average value (xsam), the transmission curve of a compander (1.1, 1.2) is automatically and briefly shifted in a way, so that ambient noise and echoes are suppressed in each transmission channel, and only the speech signal is transmitted.
