Title: A primal meet cut processing system
Inventor: MCDONNELL DECLAN ARTHUR
IPC: A22C18/00
Filed: 2009-07-20
Abstract: Boneless beef primals from a paced de-boning system 2 enter a primal trimming system 3. Primals are weighed on a dynamic scale 60 so that the de-boning yield can be derived. Weighed primals are transported on an intelligent conveyor 42 and diverted into one of eighteen trimming stations 61 using pneumatic gates 62. At each trimming workstation 61, the operator recieves cut identification and butchery information via the interface 69. The operator trims the primal to the identified specification. Trimmed primal(s) 66, low visible lean trimmings 64, high visible lean trimmings 65, fat 63 and bone 67 are placed into individual buffers for that primal. Successful completion of the task is confirmed by the operator using the interface 69. All products (except bones) are then automatically released from the buffers onto a take away intelligent trimmings conveyor 90 so as to maintain traceability of all products from that primal. The delivery of the products onto the trimmings conveyor 90 is timed to maintain gaps between the products on the conveyor 90. Individual products from the trimming station 61 are weighed on a dynamic weigh scale 95 and registered into the line control system to provide real time yield and production speed control to a quarter. Trimmed primals are diverted to a membrane skinning line 80. Cuts are diverted by a gate 86 and diverted cuts are automatically fed into a continuous skinning machine 81. Cylindrical shaped primals are fed to a manual skinner 82. Skinned pieces exit the skinner and are led by a conveyor 81a to a main conveyor 83 to workstations 85 where the lean cuts are inspected and final trimming such as removal of any membrane not removed by machine is performed. Skinned cuts are delivered onto an overhaul conveyor 84 to the final packing station 88. <Figure 1>

The valve housing is further provided with at least one valve ( 23 ) arranged to open and close to the flow of drilling fluid based on measured values of downhole physical parameters or on signals from the surface in order to permit the through-flow of a sufficient volume of drilling fluid necessary to adjust and maintain the annular fluid velocity of the drilling fluid and the wellbore pressure within optimal operating conditions.

Abstract: A selective optical actuation system for a plurality of electrical devices (20) comprises a variable pulse frequency pulsed light source (10) and an optical fibre network (12, 13, 14) distributing the light pulses to actuation gateway for each device, comprising a photovoltaic converter (16) whose correspondingly pulsed electrical output is applied to a ferroelectric transformer (18). Only if the pulse frequency is within the resonant band for a given transformer will the voltage be raised above a threshold value required to actuate that device. Choice of light pulse frequency thereby determines the device(s) to be actuated.
