Patent CA-2026484-A1 (CA)
Inventor: FAHY ARTHUR J
IPC: F16H25/04
Filed: 1990-09-28
Abstract: ABSTRACT                            (Figure 1 refers) A drive mechanism has two parallel shafts (2,3) provided with overlapping circumferentially-extending spiral teeth (4,5) of the same hand. The shape and positioning of the teeth is such that when one of the shafts is rotated, the steep flank surfaces (7,9) of its teeth engage the steep flank surfaces (9,7) of the teeth of the other shaft and force it to rotate in the same direction. Unidirectional drive may be obtained by providing each tooth with a gently sloping flank surface (8,10) on one side. The engagement of the gently sloping flank surfaces prevents rotation of the shafts if the driving torque is reversed.

Title: Method for controlling tension in a metal rolling mill
Inventor: FAPIANO DONALD J
IPC: B21B37/52
Filed: 1991-04-30
Abstract: PATENT     ABSTRACT  A method is provided for controlling interstand tension by roll gap adjustment to reduce gage variations caused by unplanned rolling velocity changes wherein a signal proportional to the tension changes produced by deviations from the desired speed ratio of adjacent stands is used to modify the conventional tension error signal before the latter signal is used to control roll gap thereby discriminating between tension changes caused by mill stand or strip physical changes, which it corrects, and tension changes caused by unplanned speed disturbances, which it ignores instead of maintaining constant tension.  The resulting system exhibits improved tolerance for imperfect stand speed control.

Patent CA-2043719-A1 (CA)
IPC: B29C65/02
Filed: 1991-05-31
Abstract: A fabric light control window covering in which fabric vanes are adhesively bonded between two sheer fabric sheets such that relative movement between the sheer fabric sheets  in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade.  The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the nonlight admitting position.          Also, disclosed are methods and apparatus for manufacturing the above window covering.  The method features linear application of adhesive  to  the vane material  which provides  for  a  uniform appearance in the finished product.  A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure. This provides for heat setting of the layers of the window covering to a uniform temperature-size relationship without inducing wrinkles or distortion into the fabric during heat setting.

Abstract: ABSTRACT OF THE DISCLOSURE:     The present invention contemplates a method and apparatus for simulating the management of a financial portfolio wherein various financial events are represented by fields on a game board.  Each player selects a token which is advanced around the game board based on random criteria such as rolling dice wherein each circuit around the board corresponds to a single year.  As each player's token is advanced about the board,  a player receives a salary and other income based on investments, receives the opportunity to make further investments and is faced with the prospect of financial setbacks, such as reduction in income and/or loss on investments.   The process continues for a predetermined period (corresponding to all or a portion of a person's lifetime) wherein the effectiveness of the player as a financial manager is measured by accumulated net worth at the end of the predetermined period.  The apparatus comprises the game board, return tables, game pieces representing the investments, the token for each player, a simulated currency, the dice, bond facsimiles, bank note facsimile, and a financial statement for each player.

Filed: 1991-06-17
Abstract: EXTENDABLE RAIL SYSTEM                          ABSTRACT           An extendable rail system is comprised of a support beam, a slide beam and a storage beam. The slide beam and storage beam extend horizontally and are supported by load rollers at one end and by a grooved roller at the other end. The grooved roller of the slide beam mates with an extension of the support beam. The grooved roller of the storage beam mates with an extension on the slide beam.           The slide beam includes first and second lateral flanges in parallel spaced relation extending from opposite sides of the slide beam to form opposite tracks along the inner sides of the flanges. A first set of roller members attached to the support beam, roll along the inner tracks of the first flange to hold the slide beam adjacent the support beam. A second set of roller members, attached to the storage beam, roll along the inner tracks of the second flange to hold the storage beam adjacent the slide beam. A brake is provided comprising a tube extending the length of the storage beam, a first member connected to the storage beam having first opening therethrough for slidable movement of the first member along the tube through the first opening and a second member having a second opening therethrough for slidable movement of the second member along the tube through the second opening. The second opening has an axis offset from the axis of the first opening. Twisting means rotatably attach the first and second members and twists the second member with respect to the first member to a position where the openings are in co-axial alignment. The first and second members are then slidable along the tube. The members are prevented from slidable movement along the tube through the openings when the openings are not in co-axial alignment.
