Abstract
Abstract A data storage means for an electrical control system such as is used with a textile, e.g. knitting, machine which produces webs of material, is provided which comprises a plurality of modules each forming a part memory, the modules, each of which includes a memory in the form of a rotary shift register, being selectively combinable to form a whole or complete memory of a desired capacity. The individual modules are detachably received in, e.g., inserted in, a carrier which includes data input(s), a data output and control input(s). The modules further include an intermediate storage device (memory) connected to the rotary shift register through a read-out device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
Data storage means for an electrical control system such as used with a textile machine which produces webs of material, said data storage means comprising a plurality of like modules each forming a part memory, said modules each including at least one memory comprising a rotary shift register, an externally controllable read-out device and an intermediate storage device connected to said rotary shift register, said read-out device including a synchronizing counter connected to said rotary shift register, an externally controllable address counter and a comparator means having first and second inputs respectively connected to the outputs of said synchronizing counter and said address counter and an output connected to said intermediate storage device, and said modules being selectively combined together to form a whole memory of a desired capacity.
Claim 2
Dependent Claim
129 words
Data storage means for an electrical control system such as used with a textile machine which produces webs of material, said data storage means comprising a plurality of like modules each forming a part memory, said modules each including at least one memory comprising a rotary shift register, an externally controllable read-out device and an intermediate storage device connected to said rotary shift register, said read-out device including a synchronizing counter connected to said rotary shift register, an externally controllable address counter and a comparator means having first and second inputs respectively connected to the outputs of said synchronizing counter and said address counter and an output connected to said intermediate storage device, and said modules being selectively combined together to form a whole memory of a desired capacity.
Claim 3
Dependent Claim
46 words
Data storage means as claimed in claim 1 wherein said synchronizing counter counts at a rate equal to the shift rate of said rotary shift register and said address counter counts at a rate which is a function of an operating rate of the textile machine.
Claim 4
Dependent Claim
47 words
Data storage means as claimed in claim 1, further comprising a carrier for detachably receiving a desired number of said modules to form a whole memory of a desired capacity, said carrier comprising at least one data input, a data output and at least one control input.
Claim 5
Dependent Claim
34 words
Data storage means as claimed in claim 3, wherein each said carrier is divided into a plurality of carrier sections adjoined to one another, and said modules are combined to form groups of modules.
Claim 6
Dependent Claim
23 words
Data storage means as claimed in claim 1, wherein each said rotary shift register comprises a plurality synchronously rotating, parallel connected shift registers.
Claim 7
Dependent Claim
35 words
Data storage means as claimed in claim 1, wherein each said module includes switching means connected to at least one control terminal of the said module, for controlling the output of said intermediate storage device.
Claim 8
Dependent Claim
51 words
Data storage means as claimed in claim 1, for an electrical needle selector arrangement of a knitting machine, the said rotary shift registers of each said module including a number of stages corresponding at least to the total number of knitting needles contained in a needle carrier of the knitting machine.
