Abstract: TITLE          Pivot Pin Assembly ABSTRACT OF THE DISCLOSURE         A pivot pin assembly according to the teachings of the present invention is shown in use in a mobile tree felling and handling device.  A pivot pin is held between first and second support members.  In the preferred embodiment, the pivot pin assembly includes firs  and second bushings having an outside male tapered surface and having an internal bore for slidable receipt on the pivot pin.  The bushing in its most preferred form includes a cut which extends through the outside male tapered surface and terminates in the internal bore to split the bushing along a radius to form a caliper-like member having first and second legs with their free ends in a spaced relation.  The support members include a female tapered opening having a size and shape complementary to and for receipt of the outside male tapered surface of the bushing.          The bushing in its most preferred form further includes a flange through which bolts threadably received in the support member pass so that the outside male tapered surface of the bushing can be drawn into and removably secured in the female tapered opening of the support member.  As the bushing is drawn within the female tapered opening of the support members, the first and second legs of the bushing move together such that the outside surface of the pivot pin is gripped by the internal bore of the bushing.

Abstract: Abstract of the Disclosure: The invention provides a process for the isolation of crystalline 1,3-cyclohexanedione from the crude product formed in the catalytic gaseous phase cycliza-tion of 5-oxohexanoic acid. Before or directly after condensation an auxiliary component consisting of at least one compound selected from the group consisting of cyclic hydrocarbons, chlorinated aliphatic hydrocar-bons and monoethers is added to the crude product, sub-sequently the mixture of crude product and auxiliary component is distilled under normal or reduced pressure until the reaction water is removed and the residual content of auxiliary component in the remaining concen-trate has attained a defined value, and the precipita-ted crystalline 1,3-cyclohexanedione is filtered off. Alternatively, the auxiliary component added may be di-stilled off substantially completely. In this case, ei-ther the same or another of the compounds or compound mixtures indicated as auxiliary component must be added subsequently to the remaining concentrate interspersed with crystals in order to obtain a substantially com-plete precipitation of the 1,3-cyclohexanedione in the form of crystals and formation of a filterable crystal pulp.     Alternatively, the crude product may be heated af-ter condensation and the crude crystallized product ob-tained optionally after cooling be mixed with the auxi-liary component. The further work-up is as described above.

Abstract: ABSTRACT           A system for transcoding signals for a 12 x 10 dot matrix into signals for a 8 x 10 dot matrix uses a two phase conversion process.  In the first phase, the pixels of each line are arranged in groups of three and in their natural order. Each group of three pixels is logically processed to obtain a group of two converted pixels.  In the second phase, the configuration of the initial four pixel block which straddles the limit or interspace between two three-pixel groups are analyzed.  Depending on the difference found during the analysis, the two pixels which are converted in the first phase are kept on either side of the limit, or are replaced by either the corresponding converted pixels of the former line or the pixels that are calculated in the second phase.

Abstract: ABSTRACT OF THE DISCLOSURE     A continuously variable multi-focal  soft contact lens wherein a continuous optical gradient in a region smaller than the maximum pupil opening is provided. The concave surface is aspheric with a desired optical power for distant viewing at the center which increases to the desired near vision power. The increase is usually about 3 to 5 diopters within 6 mm of the anterior optical zone (AOZ) which is approximately 9.7 mm in diameter when wet.          Outside this 6 mm zone the concave surface is essentially spher-ical.  The concave surface is an aspheric curve having a steeper curve in the middle than a base curve r2.  The curve at the center is the steepest and is designated as r2'.  Once r2 and r2' curves are determined, the thickness of the lens (t) and the radius of curvation for AOZ designated r1 is calculated using the desired optical power at the apex of the lens (Pw) and desired thickness at the junction (JTK) of the AOZ, based on the following equation:                     wherein Exp is the expansion factor and n is the index of refrac-tion of the lens when wet, all other dimension in the dry state, before expansion.  The lenses may be manufactured by lathe cut and polish means using the squeeze method or may be duplicated by molding and casting.

The integral assembly de-fines a number of socket areas arranged in two parallel rows which communicate with a flux rinsing drainage system comprising a plurality of drainage paths of two different configurations which lead to orifices in the assembly exterior located away from the contacts. Drainage paths of the first type include a drainage chute in the socket area floor which lead directly to the exterior via an opening in the bottom of the drain-age chute. The second type of drainage path includes a similar drainage chute leading to a large drainage opening that communicates with an extended oval-shaped centered recess which contributes a dual function of effecting a snap-on locking assembly arrangement.  The drainage system includes a large interconnecting space which enables each pair of adjacent contacts to be served by both configurations of drainage paths.  The contacts have question-mark-like configuration in which the upper portion is arranged in the respective socket area to effect a spring-loaded contact with the lead of an integrated circuit such that a gas-tight high pressure connection is achieved there between.  The contact structure itself precludes permanent deformation of the upper free end during insertion of the IC lead and the socket area housing is shaped to prevent its dislodgement during IC lead removal.

Abstract: ABSTRACT         An error correction code data communication system of the present invention has a transmitter and a receiver. The transmitter includes an encoder for adding a correction code to a data signal to be transmitted and a scrambler for randomizing the data signal.  The receiver includes a descrambler for descrambling the data signal randomized by the scrambler, and a decoder for correcting a code error by means of the error correction code.          The transmitter in accordance with the present invention comprises a random signal generator for generating a random signal in a repetitive pattern having a predetermined period.  The scrambler includes circuitry which modulo 2 adds an output of the random signal generator to both a data signal inputted to the encoder and a data signal outputted from the encoder.  The receiver comprises a random signal generator for generating a random signal in the same pattern as the signal generated by the first-mentioned random signal generator.  The descrambler includes circuitry which modulo 2 adds an output of the second-mentioned random signal generator to both a data signal inputted to the decoder and a data signal outputted from the decoder.  The receiver further comprises moni-toring circuitry for monitoring a code error in the decoder, and circuitry for setting up synchronization of the second-mentioned random signal generator in response to an output of the monitoring circuitry in such a manner as to reduce the code error.  The inven-tion dispenses with the need for a special synchronizing bit and permits descrambling without enhancing data errors developed in the transmission path.

Abstract: Abstract of the Disclosure Multiple Threshold Wheel Slip Control Apparatus and Method Anti-wheel spin control systems are useful, for example, in industrial off-road vehicles.  It is desirable that such systems operate automatically and not be unduly influenced by false slip signals caused by steering of the vehicle.  It is further desirable that the operability of the control be readily determined by the operator.  The instant anti-spin control in one embodiment includes apparatus for producing a slip signal having a value responsive to the difference in rotational velocity between the vehicle wheels, and means for producing a test signal.   Processor apparatus receives the slip signal and test signal, compares the slip signal value with a first predetermined reference value in response to receiving the slip signal in the absence of the test signal, and compares the slip signal value with a second predetermined reference value in response to receiving both the slip signal and the test signal.  A brake control signal is produced in response to the slip signal value exceeding the compared reference value, and the braking mechanism corresponding to the slipping wheel is activated.
