Patent CA-2057384-A1 (CA)
Inventor: DROGO DE JACOVO ROSARIO
IPC: G10L19/12
Filed: 1991-12-11
Abstract: The set of possible excitation signals is subdivided into a plurality of subsets, the first of which provides the contribution to the coded signal necessary to set up a transmission at a minimum rate guaranteed by the network, whilst the others supply a contribution which, when added to that of the first subset, causes a rate increase by successive steps. At the receiving side, a decoded signal is generated by using the excitation contribution of the first subset alone if the coded signals are received at the minimum rate, whilst for rates higher than the minimum rate the contributions of the subsets which have allowed such rate increase are also used. <IMAGE>

Title: Rear motor vehicle alerting bright light dimming signal and control system
Inventor: ADELL ROBERT
IPC: B60Q1/50
Filed: 1992-01-27
Abstract: A rear motor vehicle alerting bright light dimming signal and control system for alerting a driver of a vehicle behind a signalling vehicle to dim his bright lights.  The signalling system is low in cost, improves vehicle safety, promotes driver courtesy and is adaptable to all motor vehicle styles and models.  A control system permits the signalling system to operate only when the stop lights and turn signal lights of a signalling vehicle are inoperative.  The signal system comprises one or more flashing lights mounted at the rear of a vehicle and a control circuit for operating the lights.  In one aspect of the invention, a signalling light is mounted on a rear package tray in a common housing with an "eye level" stop light and, when operative, transmits a flashing high intensity beam of colored light to alert the driver of the rear vehicle.   The control system has two states, a normally off state and an operating state wherein the signal light flashes for a predetermined time.  In an alternate embodiment the signal lights are automatically activated by a bright light from a rear vehicle.

Inventor: HUNTER KEVIN D
IPC: G07B17/00
Filed: 1992-10-23
Abstract: A method and system for analyzing the usage of postage meters with respect to the history of meter recharges for the purpose of detecting fraudulent or improper usage of the meters. The apparatus includes an optical character recognition system which scans mail pieces in a stream of mail pieces to recognize postage amounts and meter identification numbers imprinted on the mail pieces. The apparatus also includes inputs for input of data representing the recharge history for postage meters which correspond to authorized identification numbers and thresholds, i.e. parameters against which expenditures arid the refill history of a particular meter will be tested. A data processing system compares cumulative amounts of postage expended by a particular meter to determine if the difference between totals expended and total recharges exceeds the thresholds, indicating the possibility of fraudulent or improper use of that meter. When such possible fraudulent or improper use is detected the apparatus diverts the suspect mail pieces from the mail stream. Tn one embodiment the apparatus may include an input for input of particular meter identification number to be diverted. In another embodiment the apparatus may check for incorrect dates on mail pieces.

Title: Dispenser for a small stack of note paper
Inventor: BODZIAK DOUGLAS P
IPC: B42D5/00
Filed: 1991-12-05
Abstract: The combination of (1) sheets (11) of note paper in a stack with each of the sheets having a narrow band of adhesive coated on its bottom surface along one edge by which the sheet is adhered to the top surface of the adjacent sheet in the stack, the sheets being stacked with the band of adhesive of adjacent sheets at alternate opposite sides of the stack, and (2) a dispenser comprising a housing (20) closely receiving the top, bottom and first side surfaces of the stack of sheets (11). The housing includes a top wall (22) of flexible material adjacent the top surface of the stack, which top wall has through flanking slits (24) parallel to and flanking side surfaces of the stack and generally centered along those side surfaces, and spaced edge surfaces (26) extending between the flanking slits. The flanking slits and edge surfaces define two opposed flap like portions (28) of the top wall and a slot (30) through the top wall between the flap like portion through which slot projects a portion of the uppermost sheet (11) in the stack. When the uppermost sheet in the stack is withdrawn through the slot the flap like portion adjacent the band of adhesive on the uppermost sheet will flex away from the stack to form a convex arcuate surface adjacent the stack along which the sheet being withdrawn and the end of the second uppermost sheet in the stack to which the band of adhesive is adhered can slide to thereby restrict curling of the sheets, and the flap like portion opposite the band of adhesive on the withdrawn uppermost sheet will place drag on the second uppermost sheet in the stack so that the force applied to withdraw the uppermost sheet will peel the uppermost sheet away from the end of the second uppermost sheet in the stack after it is withdrawn through the slot rather than fully withdrawing the second sheet through the slot.

Inventor: REVYN RONALD M
IPC: F16D65/10
Filed: 1993-06-16
Abstract: A composite brake drum particularly adapted for motor vehicle applications.  The brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum.          The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular rings or loops spaced axially within the brake drum cylindrical portion.  Axially extending locator wires are mechanically fastened to the reinforcing loops and serve to locate the loops.  End portions on the locator wires contact only one of the mold halves forming the mold cavity and enable the device to be essentially self-locating without crossing the parting line of the mold.  The end portion of the locator wires contacting the radially outer side of the mold cavity is formed with a spring bar to enable the locator wires to move outward as the reinforcing loops are thermally expanded during the casting process.  By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.  The composite brake drum is fabricated by pouring molten iron into the mold and then performing finish machining operations.

Title: Process for the production of a fiber material and process for the dyeing of the modified fiber material with anionic textile dyes
Inventor: SCHRELL ANDREAS
IPC: D06P3/82
Filed: 1993-07-23
Abstract: Abstract of the Disclosure:            Process for the production of a modified fiber material and process for the dyeing of the modified fiber material with anionic textile dyes.            Fiber materials can be modified by applying heterocyclo-aliphatic compounds containing at least one primary, secondary or tertiary amino group or quarternary ammonium group,  the hetero portion of which in the ring is a carbonic   ester radical of the formula -O-CO-O- or a carbamic  acid  radical  of  the  formula  -O-CO-NH-,  in aqueous alkaline solution by exposing the fiber material to these compounds at a temperature of between 60 and 230°C. The characteristic of the modified fiber material is that it can be dyed with dye solutions of water-soluble, anionic textile dyes which are low in electro-lytes or entirely free of electrolytes and/or are low in alkali or entirely free of alkali. The advantage of a dyeing process carried out in this manner, in particular for fiber-reactive dyes, is that fixation of the dyes under alkaline conditions is unnecessary.
