Abstract: METHOD AND APPARATUS FOR SOFT REJECTION         OF A CLUTCHED LOAD ABSTRACT OF THE DISCLOSURE           A system for coupling a large load to at least one electric motor through a respective friction clutch and for uncoupling the load from the motors in a manner which reduces the disturbance on the supply line which provides power to the motors.  The system has a control which is responsive to a start signal to operate each clutch from its disengaged condition to its fully engaged condition at a predetermined rate selected to avoid overheating of the clutches while providing a minimum disturbance to the supply line. The time interval for operating the clutch from its disengaged condition to its engaged condition is a first time interval.  The control is also responsive to a stop signal to operate each clutch from its fully engaged condition towards its disengaged condition at a predetermined rate, slower than an abrupt rate, for a second time interval, and at the end of the second time interval at an abrupt rate.  The time interval for the abrupt rate of change following the second time interval is a third time interval.  The sum of the second and third time intervals is less than the first time interval.

Abstract: ABSTRACT : "Method of encoding n-bit information words into m-bit code words, apparatus for carrying out said method, method of decoding m-bit code words into n-bit information words, and apparatus for carrying out said method".           A method of encoding n-bit information words into m-bit code words and the other way round is described, which code words have a specific disparity d and a digital sum value which is limited to values p and q. In order to enable encoding and decoding without the use of an extens-ive look-up table use is made of a series of numbers which is a modified version of numbers in conformity with the Newton binomial. By means of this modified series the n-bit information words, which are arranged in conformity with their binary weights, are mapped lexicographically and unambiguously onto code words with limited digital sum value, and the other way round.

Abstract: ABSTRACT     An improved dual layer anti-reflective coating for use in a photoresponsive semiconductor device is disclosed. The coating has a low parasitic absorbance in the range of about 475 to 600 nanometers.  The dual layer has an incident light layer and an intermediate layer. The light incident layer may be a transparent conductive oxide.  The intermediate layer is formed of a silicon alloy including at least one band gap energy widening element and may be the outermost layer of the device.  The intermediate layer has an index of refraction between the indexes of refraction of the incident light layer and the underlying photoresponsive semiconductor device. The relative thicknesses of the incident light layer and intermediate layer are chosen to maximize the amount of light transmitted to the photoresponsive device.

Abstract: ABSTRACT OF THE DISCLOSURE An optical recording and reproducing apparatus having an erasing function provides a practical apparatus which can effect recording, reproducing and erasing of signals in an erasable recording film by applying laser beams thereto.  A substantially circular first fine beam spot is formed by a beam source such as a laser, while an elliptical second beam spot for erasing purpose, having longer axis extending in a direction tangential to the guide track on the recording medium, is formed by another beam source such as a laser, so that both beam spots are disposed in close proximity of each other on the same guide track.  The power of the intensity profile of the erasing beam spot is so controlled that the highest intensity is obtained in the leading end portion of the erasing beam spot as viewed in the direction of the scan, so that the signal can be erased stably and reliably with minimal erasing power.   The portion of the recording medium scanned by the erasing beam spot is scanned by the recording beam spot so that the erasing and recording are carried out substantially simultaneously.

Abstract: ABSTRACT     A method and apparatus for pressure testing containers in peripheral cells in a rotating turret is disclosed in which high pressure air in tested containers is initially discharged into a low pressure reservoir down to a predetermined low pressure and the residual air at the low pressure then discharged to the atmosphere with little sound generation.          Incoming containers to the testing apparatus are initially supplied with pressurized air at a low pressure from the low pressure air reservoir and then supplied with pressurized air from a high pressure air supply, preferably a high pressure air reservoir, to achieve the desired test pressure.  The low pressure reservoir and the high pressure reservoir are incorporated in the rotating turret structure and are in communication with a closure cap for each cell by distribution means including a double-acting valve during selected portions of rotation of the turret.

Abstract: Abstract of the Disclosure A  pair  of  elongated,  generally  trans-versely triangular deflector members are attachable to opposite, upstanding sidewalls of the foraminous, platform-like cleaning shoe of a combine for the purpose of preventing disproportionate accumulation and build-up of crop materials on the downhill side of the cleaning shoe when the combine is performing harvesting  operations  on  sidehill  slopes.    The deflector members are fixed to such sidewalls for reciprocation with the shoe during agitation thereof and are provided with upwardly and inwardly ex-tending baffle surfaces having the ability to re-direct crop materials and air currents back toward the central portion of the shoe to counteract the effective gravity tending to cause  the dispropor-tionate accumulation of materials against the down-hill sidewall.  Through the inclined baffle surfaces and oppositely inclined feeder plates on downwardly and inwardly inclined surfaces of the members, the materials tend to be spread more evenly over the entire surface area of the shoe than would otherwise be the case in sidehill slope situations, to the end that grain loss is reduced and cleaning efficiency is increased.

Title: Bit interleaved multiplexer system providing byte synchronization for communicating apparatuses
Inventor: MANNING DAVID J
IPC: H04J3/16
Filed: 1987-06-15
Granted: 1990-01-30
Abstract: ABSTRACT       A bit interleaved multiplexer system permitting byte synchronization of apparatuses communicating thereon without the consumption of additional aggregate bandwidth is provided. The system comprises a multiplexer, a demultiplexer, and an aggregate line.  The multiplexer includes a transmit frame which includes a memory means and at least one recirculating counter which is programmed according to a framing algorithm, and a transmit data buffer and transmit mark buffer for each terminal which is to be connected to the system.  Every time the transmit frame requests a predetermined bit of a byte (e.g. an MSB), a "1" is marked in the mark buffer.  When a bit leaves the mark buffer it causes the terminal to write a bit into the transmit data buffer, with the written bit being an MSB when the bit leaving the mark buffer is a "1".  By arranging the delay through the transmit mark and data buffers to be equal to I(L) + C, where I is an integer greater than zero, L is the length of a byte, and C is a contant phase shift, when the transmit frame requests an MSB, an MSB will be sent by the transmit data buffer C requests later.  If C is set to zero, an MSB will be sent when the transmit frame so requests.  The demultiplexer of the invention includes a receive frame which is synchronized with the transmit frame and which includes a memory means and at least one recirculating counter, and a receive data buffer and receive mark buffer for each terminal which is connected to the system.  Every time the framing algorithm indicates that an M&B is being received by the receive frame, a "1" is marked into the receive mark buffer while the bit is forwarded to the receive data buffer.  Because the receive mark and receive data buffers are equal in length, the terminal receiving information from the buffers will be provided with the information as to whether the received bit is an MSB.
