Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
A weighing system comprising a plurality of weighing devices, characterised by a plurality of computer units respectively associated with said weighing devices, each of said computer units including a central processing unit (CPU), read-only memory means (ROM) and read-write memory menas (RAM), said read-only memory means (ROM) containing an operating system program which causes said central processing unit (CPU) to receive and store in said read-write memory means (RAM) processing programs and parameters and to control corresponding ones of said weighing devices by carrying out said processing programs with said parameters.
Claim 2
Dependent Claim
91 words
A weighing system comprising a plurality of weighing devices, characterised by a plurality of computer units respectively associated with said weighing devices, each of said computer units including a central processing unit (CPU), read-only memory means (ROM) and read-write memory menas (RAM), said read-only memory means (ROM) containing an operating system program which causes said central processing unit (CPU) to receive and store in said read-write memory means (RAM) processing programs and parameters and to control corresponding ones of said weighing devices by carrying out said processing programs with said parameters.
Claim 3
Dependent Claim
23 words
A system as claimed in Claim 1, characterised by a main computer unit which includes a program-storing memory means containing said processing programs.
Claim 4
Dependent Claim
27 words
A system as claimed in Claim 2, characterised in that said main computer unit includes input means for receiving programs and parameters from an external memory medium.
Claim 5
Independent Claim
22 words
A system as claimed in any preceding claim, characterised by a communication line to which all of said computer units are connected.
Claim 6
Independent Claim
53 words
A system as claimed in any preceding claim, characterised in that said weighing devices are parts of article batch handling units of a combinational weighing system, each of said article batch handling units including a feeder to transport articles to be weighed and hoppers for temporarily holding, weighing and discharging an article batch.
Claim 7
Dependent Claim
36 words
A system as claimed in Claim 5, characterised by a dispersion feeder for supplying said articles to be weighed to said article batch handling units, one of said computer units serving to control said dispersion feeder.
Claim 8
Dependent Claim
38 words
A system as claimed in Claim 5 or Claim 6, characterised by a discharge unit with intermediate hoppers and timing hoppers, one or more of said computer units serving to control said intermediate hoppers and said timing hoppers.
Claim 9
Independent Claim
31 words
A system as claimed in any preceding claim, characterised in that said weighing devices include hardware components, and said read-only memory means stores hardware-related programs directly related to said hardware components.
Claim 10
Dependent Claim
36 words
A system as claimed in Claim 8, characterised in that said operating system program causes said central processing unit to jump from one of said processing programs to one of said hardware-related programs by an interrupt.
Claim 11
Dependent Claim
67 words
A weighing system comprising a weighing device, a computer which controls the operation of said weighing device and receives signals from said weighing device, and memory means storing programs for said computer, characterised in that said memory means includes first memory means which stores programs directly related to hardware components of said system, and second memory means which stores programs not directly related to said hardware components.
Claim 12
Dependent Claim
67 words
A weighing system comprising a weighing device, a computer which controls the operation of said weighing device and receives signals from said weighing device, and memory means storing programs for said computer, characterised in that said memory means includes first memory means which stores programs directly related to hardware components of said system, and second memory means which stores programs not directly related to said hardware components.
Claim 13
Dependent Claim
18 words
A system as claimed in Claim 10, characterised in that said first memory means includes a read-only memory.
Claim 14
Dependent Claim
22 words
A system as claimed in Claim 10 or Claim 11, characterised in that said second memory means includes a read-write memory means.
