Abstract: ENGINE-SENSING DRAFT CONTROL SYSTEM WITH MULTIPLE FEEDBACK COMPENSATION MECHANISMS                   ABSTRACT OF THE DISCLOSURE     An automatic feedback control system for use with an off-road vehicle having an adjustable-elevation, ground-engaging implement, such as an agricultural tractor with a three-point hitch and a plough or cultivator, is disclosed. The automatic control system provides an engine-sensing draft control system which adjusts the height or elevation of the ground-engaging implement so as to maintain the draft or load forces experienced by the vehicle at a substantially constant level. The determination of the draft being produced by the ground-engaging implement is determined by the engine speed deviation from a target point speed which is indicated by an operator-set desired no-load engine speed and an operator-set engine lug-down value or load. To provide proper operation of the engine-sensing draft control system, multiple feedback compensation mechanisms are provided, including a throttle compensation function, an electrohydraulic valve compensation function, a slip-sensing function, a sensitivity (deadband) adjustment, a maximum implement-lowering rate function, and an automatic downshift signal function to cause the transmission of the tractor to downshift to a lower speed to avoid engine stall under certain conditions.

Abstract: ABSTRACT OF THE DISCLOSURE      A sealed, air-containing vehicle suspension assembly. The assembly includes an endless track unit trained over a pair of wheel units each supported by the end portion of an axle, a pair of side plates, and a pair of dynamic seal assemblies.  The dynamic seal assemblies each include a diaphragm portion with its outer margin secured to outer margins of the track unit and its inner margin carried by support units extending inwardly from the track.  The primary  seal unit has a tubular cross section and its inner sidewall affixed to the inner diaphragm margin.  A part of the primary seal outer sidewall has a smooth sidewall sealing surfaces which engages an inwardly facing surface of its associated end plate along a path generally parallel to the travel path of the track.  The primary seal unit also includes spaced apart air inlet openings between its sidewall sealing surface and the inner margin along which it is joined to the diaphragm, whereby the air within the support seal assembly may enter the primary seal unit to maintain an inflation and sealing pressure.

Title: Apparatus for controlling linear motors
Inventor: MAC MUNN GEORGE D
IPC: G05B19/416
Filed: 1988-08-15
Granted: 1993-05-11
Abstract: ABSTRACT         A reciprocatable shuttle employed to advance a variable number of article carriers through successive work stations is driven on forward and return movements by a plurality of energizable linear motor stators for which the shuttle forms a common reactor.  Energization of the stators is controlled by a programmable logic controller in response to inputs from velocity measuring circuits which determine the difference in the actual velocity of the shuttle rela-tive to a desired maximum forward velocity, return velocity and creep velocity; to inputs from distance measuring cir-cuits which determine the distance travelled by the shuttle relative to a forward deceleration point and to a return deceleration point; to inputs which establish the return or forward position of the shuttle; and, to inputs which count the number of article carriers to be advanced.  The pro-grammable logic causes the stators to be progressively energized at timed intervals in response to a velocity ON signal to accelerate the shuttle to that velocity; to main-tain the shuttle at that velocity; and, in response to a distance signal, to reversely energize the stators until the shuttle reaches the creep velocity.  The maximum number of stators energizable is limited in accordance with the ar-ticle carrier count,  and the sequence in which the stators are energized is rotated on each forward-advance movement cycle of the shuttle.

Granted: 1993-09-07
Abstract: Controlled Ink Drop Spreading in Hot Melt Ink Jet Printing Abstract In the particular embodiments described in the specification, a hot melt ink jet system includes a temperature-controlled platen (16) provided with a heater (25) and with a thermoelectric cooler (28) electrically connected to a heat pump (26), and a temperature control unit (22) for controlling the operation of the heater (25) and the heat pump (26) to maintain a substrate (10) on the platen (16) which receives the ink (15) at a temperature which provides a desired spot size without causing print-through.  In certain embodiments, the substrate temperature is from about 20°C above to about 20°C below the melting point of the ink and is determined by subtracting half the difference between the jetting temperature and the temperature at which the ink has a viscosity of about 200-300cp from the latter temperature.  The apparatus also includes a second thermoelectric cooler (35) to solidify hot melt ink in a selected zone more rapidly to avoid offset by a pinch roll (12) coming in contact with the surface of the substrate (10) to which hot melt ink (15) has been applied.  An airtight enclosure (17) surrounding the platen (16) is connected to a vacuum pump (21) and has slits (18,19) adjacent to the platen to hold the substrate (10) in thermal contact with the platen (16).

Abstract: ABSTRACT OF THE DISCLOSURE         An integrated accounting system is applied to a network structure which includes a telephone network and a packet network.  A packet exchange in the packet network includes a circuit for measuring a communication data quantity within the packet network during a communication between a first terminal which has an advance payment function and is connected to a telephone exchange in the telephone network and a second terminal which is a packet mode terminal connected to the packet exchange.

The telephone exchange includes a circuit for generating a control signal for every predetermined accounting unit which is dependent on a duration and distance of a communication within the telephone network, a circuit for sending the control signal generated therein and the control signal received from the gate way to the first terminal, and a circuit for initially sending the control signal when a call out from the first terminal is detected.  The first terminal collects an amount of money responsive to the control signal received from the telephone exchange.

Abstract: Abstract of the Disclosure A predetermined unsymmetry of a bipolar waveform is  detected  by  apparatus  which  includes  a  circuit  which generates a pulse for each zero crossing of the waveform. Each zero crossing pulse triggers a first retriggerable one-shot for a first interval T1.  Timing out of the first one-shot triggers a second retriggerable one-shot for a second interval T2.   If both the first and second one-shots have timed out a third one-shot is triggered for a third interval T3.   The intervals are selected such that twice T1 plus T2 is equal to the period of one cycle of the bipolar waveform so that triggering of the third one-shot is an indication of a predetermined unsymmetry determined by relative values of T1 and T2 of the bipolar waveform.  T3 is selected such that two symmetrical cycles of the bipolar waveform are required to  clear  the  unsymmetry  indication.    The  apparatus  is applied  to  blocking  a  false  trip  signal  from  a  reverse current  relay  in  response  to  the  in-rush current when a transformer is energized with little or no load.
