Title: Clock recovery system capable of automatically switching a direction of a clock pulse sequence from one to another
Inventor: KISHI KAORI
IPC: H04L69/40
Filed: 1992-06-23
Abstract: Abstract of the Disclosure:         In a clock recovery system for use in a ring-shaped synchronization network which comprises a master transmission device and a plurality of slave transmission devices, a clock pulse sequence is circulated in a predetermined direction from the master transmission device through the plurality of the slave transmission devices in a normal state and a fault indication signal is transmitted in the predetermined direction from one of the slave transmission devices that detects interruption of the clock pulse sequence.          Responsive to the fault indication signal, the master transmission device transmits a switch indication signal in a reverse direction to the one slave transmission device so as to switch the direction of the clock pulse sequence in each slave transmission device.  Responsive to the switch indication signal, the one slave transmission device transmits a switch completion signal to the master transmission device in the predetermined direction.  Thus, the direction of the clock pulse sequence is automatically switched from the predetermined direction to the reversed direction.

Patent CA-2103326-A1 (CA)
Inventor: RICKETTS JONATHAN E
IPC: A01F12/10
Filed: 1993-11-17
Abstract: ABSTRACT OF THE DISCLOSURE An axial-flow combine including a feeder mechanism and an axial flow rotor assembly having an impeller assembly arranged at a forward end of a rotor. The feeder mechanism includes a housing which is pivotally connected to the combine about atransverse axis. The feeder mechanism housing envelops a conveyor assembly used to impart linear movements to the crop materials as they are advanced toward the rotor assembly. Prior to their introduction to the rotor assembly, the linearly advancing crop materials are discharged from a rotary member. A salient feature at the present invention involves the communicative relationship established between the rearmost rotary member from which the crop materials are discharged and the foremost end of the impeller assembly. The longitudinal spacial relationship therebetween is such that the crop material flow is permitted to transmute from the linear flow imparted thereto as the materials moved toward the rotor assembly and a rotary or circulatory flow imparted thereto as the materials are introduced to the whirling blades of the impeller assembly.

Filed: 1993-08-06
Abstract: ABSTRACT      A  quarry  pulverizer  for  use  as a reduction process machine  for  rocks and mineral bearing ores is provided for use.  The purpose of the quarry pulverizer is to enhance the ability  to meet product grading requirements without adding cost  or  time to the operation, to reduce maintenance costs associated with these types of machines, to increase feeding capacity, to demonstrate how a centrifugal reduction machine can  eliminate  wear  to its central rotor, and to present a pulverizer  with  an  overall  modular  design  that  can be tailored  to  meet  a  customer's needs.  The invention also introduces  the  concept  of how a static impact area may be changed into a dynamic impact area and subsequently increase reduction  efficiency.  A  quarry pulverizer is provided to act  as  a  reduction  process  machine for rocks or mineral bearing  ores.  It consists of a top cover with a collecting hopper  to  accept  material  feed  stock,  together  with a vertically   mounted  cup-shaped  rotor  that  receives  the material  feed  stock  from  the top cover and centrifugally accelerates  the  material  upwardly  and  over  its rim.  A modular system of shelves surrounds the rim of the rotor cup that  bank  up with the material or inlaid with metal/blocks and  act  as an impacting area for the oncoming of material, chutes  where  the  material may gravity discharge.  A motor turns  the  rotor cup by means of a shaft running vertically along the longitudinal axis of the pulverizer.
