Abstract: ABSTRACT           A radiator for an automotive engine has a filler neck having a coolant pass therein.  The filler neck has both an inner tubular member and an outer tubular member so that the coolant pass is formed between the inner surface of the outer tubular member  and  the  outer surface  of  the  inner tubular  member.   The  coolant  pass  is  connected  with  a connecting pipe in order to introduce the coolant within the coolant  pass  toward  the  connecting  pipe.   The coolant introduced into the connecting pipe is, then, flows toward a reserve tank.         Since  all coolant  flowing toward the  connecting pipe  is  orientated  its  vector while  passing  through the coolant  pass,  the  coolant  can  be  introduced  into  the connecting pipe smoothly.

Patent CA-1334490-C (CA)
Inventor: BRUEGGEMANN HARRY P
IPC: H04N1/23
Filed: 1988-07-14
Granted: 1995-02-21
Abstract: This invention relates to a pyramid polygon scanner without cylinder optics wherein the effects of jitter are reduced by the use of a start of scan detector situated at a predetermined angle from the normal (vertical) position. The start of scan detector is rotated about an axis through the nominal scan line. Thus, if tilt (not the draft angle) is present in the rotating polygon system and jitter is generated, the rotation angle of the split detector moves the jitter to the beginning and end of scan, leaving the center of scan free of the effects of jitter. The angle of the split detector is in approximate relation to the angle of incidence at the first reflection on the rotating polygon.

Granted: 1992-12-15
Abstract: ABSTRACT             A method and apparatus for controlling the ripening of fresh produce.  The device comprises a chamber having a ceiling and floor and four walls.  Positioned in the chamber is a frame adapted to support two rows of palletized produce each of said rows having two tiers.  The two rows are spaced apart from one another to form an intersitial volume therebetween and the two rows are spaced from the walls and ceiling to form a circulation space.  An end tarpaulin, a ceiling tarpaulin and a false end wall together with rails and sealing strips seal the top and ends of the palletized produce as well as the top spacing therebetween define a sealed intersitial volume between the rows.  An air handling unit introduces air into the fluid circulation space and exhaust fans remove fluid from the intersitial volume.

Title: 12-step commutation device for an electric motor
Inventor: HENDRICKS HOWARD F
IPC: H02P6/14
Filed: 1988-09-23
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE   12-step commutation in a brushless DC motor is achieved by six shaft-mounted commutation sensors and circuitry which permits inexpensive shaft-angle decoding for coil excitation. The commutation signal devices are Hall sensors arranged in two sets.  A first set is arranged to produce the desired switching signals every 120 electrical degrees; a second set of three Hall sensors is similarly arranged equally spaced between the electrical switch points of the first set, however, the second set of sensors is wired together through the process of EXCLUSIVE-ORing to form a single, fourth output.  Thus, the six Hall sensors are configured to produce four output signals which may be inexpensively decoded using a standard 32 X 8 PROM.  A further refinement includes current modulation to the field coils in order to equalize the torque output of alternate steps.  In one embodiment, this is accomplished by reducing the gain of the motor's servo amplifier so that the desired current shift is achieved by changes in the motor's load impedance.

Abstract: In a digital radio transmission system for transmitting independent dual data by using cross polarization, an interference canceller detects cross polarization interference either directly or indirectly.  An interference compensating signal is generated and applied to the main signal to cancel the interference element.  In a case where no interference element is present, deterioration of cross polarization discrimination from an interference cancelling circuit is prevented by first determining whether an interference element actually exists and applying the interference compensating signal only when it does exist.  The interference compensating signal can be attenuated based on the value of interference element so as to prevent undo deterioration of the cross polarization discrimination when the interference element is minimal.

Abstract: Abstract A video signal is coupled from the output of a display driver amplifier to an image display device via a coupling network including cascaded emitter follower transistors of opposite conductivity type.  First and second diodes are respectively connected across the base-emitter junctions of each transistor and are poled for forward current conduction in a direction opposite to that of the associated base-emitter junction.  The coupling network significantly reduces the value of capacitance of the display device as presented to the output of the driver amplifier, thereby improving positive and negative video signal transient response.

Abstract: OPTICAL FEEDBACK ISOLATOR            Abstract of the Disclosure Method and apparatus for isolating optical feedback in a laser interferometer having a laser light source from which a linear polarized outgoing laser beam of certain polarization orientation is derived.  The interferometer also redirects the outgoing laser beam to form a return laser beam directed to a receiver.  The outgoing laser beam and the return laser beam are physically close and are substantially parallel.  The linearly polarized outgoing laser beam is converted to circular polarization.  A portion of the circularly polarized return laser beam directed toward the laser light source is converted back to linear polarization with polarization orientation orthogonal to the polarization orientation of the outgoing laser beam.  A portion of the circularly polarized return laser beam directed toward the receiver is converted back to linear polarization with polarization orientation being substantially the same as the polarization orientation of the outgoing laser beam.  The portion of the return laser beam with polarization orientation orthogonal to the polarization orientation of the outgoing laser beam is directed away from the laser light source, and the portion of the return laser beam with polarization orientation substantially the same as the polarization orientation of the outgoing laser beam is directed toward the receiver.
