Abstract: POLLING COMMUNICATION SYSTEM                  WITH PRIORITY CONTROL                  ABSTRACT OF THE DISCLOSURE       A communication system containing: a master station, a plurality of slave stations each for communicating with the above master station, a two-way transmission line connecting the above master station and the above plurality of slave stations. Each of the above slave stations sends a request for a further communication with the above master station, to the master station when its own slave station is allowed to communicate with the master station and its own slave station has the above request. The above master station detects the request for a further communication with the above master station in a signal sent from a slave station, and memorizes a slave station from which a request for a further communication with the master station is detected, until an allowance is sent to the slave station from the master station corresponding to the memorizing of the slave station. The master station has a cyclic address pointer which points out an address of a next one of the above slave stations in a cyclic order when no slave station is memorized in the master station. m e master station outputs an allowance to communicate with the master station: to a slave station which is memorized in the master station; or to a slave station the address of which is pointed out by the above cyclic address pointer when no request is memorized in the master station.

Title: Short dwell coater apparatus for coating a web with a coating material
Inventor: BUSKER LEROY H
IPC: B05C11/04
Filed: 1990-09-24
Abstract: A short dwell coater apparatus is disclosed for coating a web with a coating material, the web moving contiguously with a rotating backing roll.  The apparatus includes a housing which is disposed on the opposite side of the web relative to the backing roll.  The housing defines a coating chamber having an upstream and a downstream end.  The chamber is connected to a pressurized source of coating material.          The chamber is exposed to the web such that the web supported by the backing roll is coated with the coating material during passage of the web past the coating chamber.  The upstream and downstream ends of the coating chamber define first and second weirs respectively.  Each of the weirs extend in a cross-machine direction such that the coating chamber is bounded by the weirs and the web moving between the weirs.  The first and second weirs define respectively first and second overflow gaps.  The arrangement is such that during use of the apparatus, when the web moves past the coating chamber, coating material is coated onto the web while excess coating material overflows through the first and second gaps for recirculating through the coating chamber.  A resilient blade is disposed downstream relative to the second weir.  The blade cooperates with the coating material coated onto the web such that the pressure exerted by the coating material on the blade is less than the pressure of the coating material within the coating chamber, so that mottling and streaking of the resultant web is inhibited while maintaining minimum pressure on the blade.

Abstract: ABSTRACT   A portable livestock barrier is disclosed which includes a rigid metal panel of open grid construction that is arranged to rest in a normal operational position that is parallel to the ground to thus form a raised grid which livestock will not cross but which can be flattened to the ground against a resilient return force when a vehicle is driven across it.  The rigid metal panel is supported by a resilient suspension which permits the panel to tilt with respect to its normal operating position and to be forced flat against the ground when the weight of a vehicle is applied to it.  The livestock barrier does not require a pit or special surface preparation for its installation.  It may be quickly installed on any solid, relatively level surface.  The unit is transportable and it can be readily moved from one location to another without disassembly.

Patent CA-2036757-A1 (CA)
IPC: H03H15/00
Filed: 1991-02-20
Abstract: A transversal equalizer is realized by employing variable gain and delay in the amplification branches of a traveling wave amplifier. Specifically, by adjusting the gain and delay in each branch, the traveling wave type transversal equalizer may be adjusted to have a complementary frequency response in order to compensate for linear channel gain and phase ripples. This approach permits the transversal equalizer to be designed without the use of resistive splitter and combiner networks and, therefore, without the use of high gain amplifiers. Without such amplifiers, splitters and combiners, the smaller physical size, which is afforded thereby, allows the transversal equalizer to be easily assembled as a hybrid integrated circuit.
