Abstract: ABSTRACT OF THE DISCLOSURE For effective use of the optical energy and yet proper operation of an automatic gain or threshold control circuit comprised by a receiver of an opti-cal data transmission system, a transmitter of the system produces an optical binary signal with at least one optical pilot pulse inserted between two se-quences of optical data pulses only when the two sequences are spaced wider from each other than a predetermined interval that would render the control cir-cuit no more operative and would thereby adversely affect correct reproduction of the data from an electrical binary signal derived from the received optical binary signal through the control circuit.  By making the pilot pulses appear more than a first prescribed duration after the last data pulse of the preced-ing sequence and a second prescribed duration before the first data pulse of the succeeding sequence, electrical pilot pulse or pulses present in the electrical binary signal are removed without deforming the reproduced data  if each pre-scribed duration is longer than the pulse width of the electrical pilot pulse and furthermore a sum of the prescribed durations and the pulse width is not longer than the predetermined interval.  The removal is possible by providing the electrical binary signal with successive delays decided in consideration of the prescribed durations and the pulse width and carrying out logic operation on the electrical binary signal and the successively delayed signals if each opti-cal data pulse lasts longer than a sum of the delays.

Abstract: TITLE       CONTROLS FOR AERIAL LIFT PLATFORM APPARATUS     INVENTOR          John L. GROVE, Ernest J. MERZ, AND Charles W. WALTERS     ABSTRACT     The present invention provides a control arrangement for the control members to control an aerial lift platform apparatus.  A control console is provided which has a first surface which is slightly inclined to the horizontal and a second surface which is slightly inclined to the vertical.  The control members which control vehicle movement, that is, drive and steering control members, are mounted on the near-horizontal surface, and extend generally vertically upwardly therefrom, although at a slight angle, for convenience.  Movement of the upper end of the drive control lever in the forward direction causes the chassis to drive forward, and movement in the rearward direction causes movement of the chassis in the rearward direction.  The steer control lever may be swung to the left to cause left steering of the chassis and swung to the right to cause right steering of the chassis, thereby providing a correspondence between lever movement and vehicle movement.          All of the upper works control members are located in close physical proximity.  The swing control lever swings about a near-vertical axis and thereby simulates and corresponds to the swinging movement of the upper works, left and right.  A boom luffing control lever is provided which is mounted for vertical swinging movement, just as is the boom, with the lever extending from the near-vertical surface, in a generally horizontal manner, so as to generally simulate the position of the boom, with resulting movement of the boom luffing control lever resulting in movement of the boom in the same direction as the lever is moved.  A boom extension control member is provided which is pulled toward the operator in order to cause extension of the boom, and is pushed away from the operator in order to cause retraction of the boom, these movements corresponding to the direction of movement of the workman's platform when the boom is extended and retracted.  There may be provided, also, a platform rotate control lever for controlling platform rotation mounted for movement so that its free end moves in an arc, in the direction of movement of the platform, left or right.  There is provided, also, a platform level override lever for controlling rotation of the platform about a horizontal axis adjacent the end of the boom, this lever being mounted on the near-vertical surface, and having up and down movement in a vertical plane in correspondence with the up and down rotation of the platform in a vertical plane.

Abstract: ABSTRACT OF THE DISCLOSURE The specification discloses a seat pitch adjustment assembly which a user can adjust upwardly or downwardly with basically the same applied force.  A seat support is pivotally mounted with respect to a supporting assembly at one point and is joined thereto at another point through a pivot bracket. The pivot bracket is pivotally mounted to the support assembly on one pivot axis and to the seat support on a second pivot axis.  The pivot bracketing includes a cylindrical wall defining at least a portion of the wall of a right circular cylinder whose axis of revolution lies on the aforesaid second pivot axis.  The cylindrical wall includes at least one helically oriented slot receiving a projection from a slide slidably mounted on the seat support member whereby movement of the slide one way or the other rotates the pivot bracket about said second pivot axis and thereby changes the relative elevation of the first pivot axis with respect thereto.  This in turn changes the pitch of the seat support with respect to the underlying support assembly and thereby changes the pitch of a seat mounted thereon.

Abstract: ABSTRACT A piston intended for use in refrigeration compressors and other applications wherein a heat barrier is provided in the piston skirt between the head of the piston and the wrist pin.  The heat barrier substantially reduces the conduction of heat from the higher temperature piston head to the wrist pin bearing surfaces, which would otherwise result in rapid wear of the wrist pin bearings and ultimate failure of the compressor.  The heat barrier preferably comprises a pair of openings extending through the wrist pin bosses in close proximity to the wrist pin holes thereby partially thermally isolating the wrist pin holes from the head of the piston.  The openings are spaced on opposite sides of an axial line extending from the piston head to the wrist pin holes so that there remains a bridge of the piston skirt material to provide the necessary support for hydraulic loads that occur when the compressor slugs.  The openings in the wrist pin bosses also provide a passage for lubricant which is pumped through them by the ram pressure that is developed on the piston return stroke. The lubricant acts as a cooling medium to cool the wrist pin bearing surfaces.
