Patent CA-2295099-A1 (CA)
Inventor: MINTEL THOMAS EDWARD
IPC: A46B9/04
Filed: 1998-06-24
Abstract: A toothbrush having a bristle-bearing head divided into at least two sections (14, 16) is disclosed. The free end section (16), when unstressed, is normally biased to assume an angle of about 15° with respect to the other, to thereby define an articulated head.      The two sections of the head have facing ends joined by a thin bridge (30) or hinge section integral with the two head sections, the bridge or hinge forming a groove between adjacent head sections. The upper surface of the bridge section is substantially flush with the upper surface of the head (opposite to the bristle-bearing surface). The space between the two facing ends is filled with a soft elastomer of about 5 to about 30, preferably about 13 to about 30 Shore A hardness. This hinge construction defines an articulated head of limited flex motion, wherein, when utilized by the average adult brusher, who applies an average brushing force of 0.5 pounds, flexes to a substantially flattened position. According to a second aspect of the invention, each end of the groove terminates in a flange at its extreme outer edge, and the groove, including the flange (32), is filled with an elastomer, which, due to the presence of the flange, is resistant to peel stresses caused by flexing of the hinge or joint.

Abstract: To provide a receiver not requiring any large circuit. A carrier-wave-phase-error table 15-1A for BPSK modulation in which a range equal to or more than 0 of I-axis is defined is prepared for a carrier-wave regenerating circuit 10A of a demodulating circuit 1A for orthogonally detecting a received signal in which digital signals according to BPSK, QPSK, and 8PSK modulations are time-multiplexed and outputting I and Q symbol-stream data I t and Q t for each symbol. When a remapper 7A outputs I0t and Q0t obtained by inversely phase-rotating I t and Q t by -~ against a received-signal-phase rotation angle ~ and generating an absolute phase of I t and Q t, a phase-error detecting circuit 70 obtains a shift angle ~' up to a target phase convergent angle of a received-signal point shown by I0t and Q0t viewed in the positive direction of I-axis according to a modulation system currently demodulated, reads phase error data corresponding to I1t and Q1m obtained by phase-rotating I t and Q t by -(~+~') by the remapper 7A through time sharing out of the table 15-1A, and corrects a phase of a reference carrier wave so that the phase error data becomes zero.

Title: Method and device for exchanging shears in the cutting to length of strips or sheets in the rolling or transport line
Inventor: MUNKER MAX
IPC: B23D1/00
Filed: 1999-07-17
Abstract: The invention relates to a method and a device for cutting to length strips (1) or sheets in the rolling or transport line (x-x), notably on a rolling table (2), using shears (3) having one blade holder (4, 4') each arranged above and below the strip (1), which blade holders are guided by means of fixing elements (5, 5';6, 6'). The invention is characterized in that the shears (3) with the blade holders (4, 4') and their fixing elements (5, 5';6, 6') are displaced sideward out of the rolling line (x-x) into a neutral parking position after each cut when a strip (1) or sheet is located in the rolling or transport line. Before displacement of the shears (3) the frontal joint between the blade holders (4, 4') or between the fixing elements (6, 6') overlapping the rolling line (x-x) is opened. For a subsequent cut the shears are moved into the rolling line such that they overlap same in a U-shape. Before the next cut the frontal joint between the blade holders (4, 4') or between the fixing elements (6, 6') overlapping the rolling line (x-x) is closed. Said joint is coupled in a positive and non-positive manner by means of a clamping element (7).
