Title: Two-stator induction synchronous motor
Inventor: SATAKE TOSHIHIKO
IPC: H02K21/46
Filed: 1991-03-18
Abstract: A two-stator induction synchronous motor includes a unitary rotor having a first rotor assembly and a second rotor assembly each of which is formed by a permanent magnet and a rotor core. The first rotor assembly and the second rotor assembly respectively have first and second respective pairs of magnetic poles of the permanent magnets disposed in relative relation such that the former and the latter are displaced by 180° or 0°, respectively, to each other. The motor also includes a phase-shifting means which produces a phase difference of 0° or 180° between a voltage induced in rotor conductive members by a rotating magnetic field generated around the first rotor assembly and a voltage induced in rotor conductive members by a rotating magnetic field generated around the second rotor assembly.The two permanent magnets are disposed in such a relation that the attracting orrepelling action of one permanent magnet and the repelling or attracting action of the other permanent magnet cancel each other, so that starting operation is not interfered with. The starting operation is the same as in an induction motor, and the running operation is as in a synchronous motor.

Patent CA-2050173-A1 (CA)
Inventor: SCHOENEBERG RAINALD
IPC: H04L27/24
Filed: 1991-08-28
Abstract: A system and method for encoding and decoding a frequency-shift keyed data signal for transmission over a non-ideal communications channel that utilizes phase-coherently  combined  halfwave   segments   of sinewaves  with  a  finite  number  of  different frequencies and equal amplitudes.  A stream of data characters is encoded into a transmit sequence {S(n)} of positive numbers which defines an ac signal of halfwave segments of sinewaves of fixed, preselected amplitude.  The ac signal encoding the stream of data characters  is  transmitted  over the communications channel and received as a perturbed ac signal.  The received  signal  is  identified  by  consecutively determining the time durations between peak values or between zero crossings of each segment yielding a receive sequence {E(n)} of positive numbers.  All or parts of this receive sequence are then compared with each of a set of preselected, stored sequences, each representing  a  stream of  none,  one  or more data characters.   The actual stream of data characters transmitted is selected as the stream producing the smallest  errors,  within  a  preselected  bound,  in comparing the stored stream-representing sequences to all or parts of the receive sequence.

Abstract: An operator for an awning type window having a sash pivotable about its top side relative to a window frame, with the operator controlling opening and closing movement of the sash relative to the frame. The operator includes a drive gear pivotally mounted to a base on the frame, a primary arm pivotable about an axis on the base, a sun gear pivotable about the axis on the base and drivably engaging the drive gear, and a secondary arm pivotally mounted to the primary arm with a planetary gear fixed thereon and drivably engaging the sun gear. A bracket is fixed to the sash side opposite the one sash side, a first connecting arm is pivotally connected at one end to the primary arm and at the other end to the bracket, and a second connecting arm is pivotally connected at one end to the secondary arm and at the other end to the bracket, where all of the arms cooperate to move the sash bottom side toward and away from the frame to control opening and closing of the sash in response to rotation of the drive gear. The base includes a fixed primary arm stop which engages the primary arm to prevent lateral shifting of the window when the sash is closed against the frame. A spacer is disposed between the first connecting arm and the sash bottom side to maintain the primary arm and first connecting arm in a sash opening configuration during initial opening of the sash from a position closed against the frame.

Title: Self-releasing lift hook
Inventor: JORRITSMA JOHANNES N
IPC: B66C1/26
Filed: 1992-01-21
Abstract: A self-releasing lift hook includes a main cylinder with a main piston slidable in the cylinder and defining a main chamber above the piston and a main chamber below the piston.  A hook is connected to one of the cylinder and the piston, and a lift ring is connected to the other.  A coil spring biases the piston in a direction which causes the hook and the ring to approach each other, so that when a load is placed on the hook, the hook and ring move apart and cause energy to be stored in the spring.  A main passage through the piston, incorporating a check valve, allows fluid to flow between the main chambers when the hook and ring are moving apart, but restrains such fluid flow when the hook and ring approach each other.  A bleed passage is provided through the piston to allow slow transfer of fluid from one side to the other of the piston.  A hydraulic accessory is activated by an increase of fluid pressure in the chamber that decreases in volume when the hook and ring approach each other, and a mechanical connection, activated by the hydraulic arrangement, causes a load attachment to be disengaged from the hook.

Title: Apparatus for determining an area coverage rate
Inventor: RENCH QUENTIN H
IPC: E01H1/00
Filed: 1990-06-25
Abstract: An apparatus (10) for determining an area of a surface which is traversed and treated by an object during a unit of time is configured for use with a movable object (11) that has a first axis (17) of a known length. The object is capable of movement along a second axis (19) and the first and second axes (17, 19) define an angle between them which is other than 0·. A signalling means (28) includes a sensor (27) which may be mounted in a motion-sensing relationship to the object (11) for providing a motion signal when the object (11) moves a distance along the second axis (19).  The motion signal has a predetermined relationship to that distance. A timing means (45) repetitively provides a plurality of timing signals, each sequential pair of which defines an interval of time of known duration. A computing means (43) is coupled to the timing means (45) and to the signalling means (28) for receiving at least one sequential pair of timing signals and at least one motion signal. The computing means (43) thereby initiates a display of the area of the surface which is traversed by the first axis (17) per unit of time and therefore treated as the object (11) moves along the second axis (19).

Title: Method and apparatus for the generation of smoothness and gloss
Inventor: LINK CHRISTOF
IPC: D21G1/00
Filed: 1992-08-06
Abstract: The invention has as its object the provision of a method and an apparatus for the generation of smoothness and gloss on paper which essentially precludes a re-erection of the surface fibers after the smoothing process. This is achieved in that the surface of a paper web (1) to be smoothed is heated to a temperature above the glass transition temperature of the fibers at the surface of the web and these fibers are deformed and fixed in the deformed state in a subsequent process step under the simultaneous action of pressure with shock cooling.  Accordingly, there is associated with each surface of the paper web (1) to be smoothed a heating device (2) and also a subsequent cooled body (5, 9, 10) which presses against the surface.
