Abstract: ABSTRACT OF THE DISCLOSURE A  low  cost,  multipurpose  digital  integrated circuit  (IC)  is  used  as  the  basic  building  block  in establishing a network communication system over a desired communication link.   The digital  IC can function as an addressable microcomputer  interface between  the network line and a remotely located microcomputer which may, for example,  comprise  any  microprocessor  based  controlled product.   In such mode, the digital IC's function is to take data from the network and pass it on to the remotely located  microcomputer  upon  command  from  the  central controller and to transmit data from the microcomputer to the central controller.  The digital IC may also function as a nonaddressable microcomputer interface between the central or master controller and the network line,  In such case the digital IC's function is to continuously take data from the central controller and place it on the network and take data from the network and pass it back to the central controller.   The  digital  IC  may  also  function  as  an addressable lead controller associated with an individual remote controlled device and responding to shed or restore load commands from the central controller over the network line.  When so used the digital IC may also be commanded to transmit a reply message back to the central controller giving information  as to the status  of the  controlled device, thus enabling the central controller to monitor a large number of remotely located controllable devices.

Abstract: In a machine for the fine comminuting and/or emulsifying of e.g. forcemeat with a conveyor worm (2) and a cutting device (6) comprising at least one cutter or knife set and at least one perforated disc, the diameters of the exit section (11) of the conveyor worm (2) and the surrounding section (9) of the housing of the cutting device (6) increase in the direction of conveying, and the machine is adapted to be driven by a motor (13) with at least one relatively high speed of rotation. 
<??>When operating with a high rotational speed, this arrangement results in that the exit end of the conveyor worm (2) together with the surrounding section (9) of the housing of the cutting device (6) act as a centrifugal pump with axial entry and exit, so that the pressure, with which the material is fed to the cutting means, is increased, and the throughput capacity of the machine is also increased due to the higher pressure produced. 
<??>Sealing problems due to the increased pressure are avoided by placing the seal (17) for the drive shaft (3) of the conveyor worm (2) in the inlet hopper (1) on the side opposite the cutting device (6), where the pressure is relatively low due to the worm carrying the material away. Thus, a simple lip seal or the like may be used.
