Abstract
Abstract A multiple operating head machine, such as a multiple spindle textile spooling machine has apparatus connected thereto to determine the operating overall efficiency of the machine by analyzing the down-time of individual spindles. Each spindle is connected to a switch which is closed when the spindle is operating, placing a resistance in series with the switch. All switches of all spindles are connected in parallel so that, when all spindles are operating an equivalent resistance is placed in a time integrating and pulse generating circuit, the pulse sequence of which supplies an indication of the integrated overall operating time of the spindles of the machines.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
202 words
Multiple operating head machine in which each machine head has an individual switch (S1-Sn) indicating, by its position, whether the machine head is running or stopped, said machine having supervisory apparatus comprising a plurality of like individual resistances (RO), one each connected in series with an individual switch (S1-Sn), a switch and a series connected resistance forming a machine head circuit; means connecting the individual machine head circuits all in parallel, whereby the equivalent instantaneous impedance (R) of the parallel circuit will be an indication of the number of operating heads at any instant of time and form a load resistance; a condenser (C), and a charging and discharge circuit therefor connected to said condenser, the charging circuit including said load resistance and having a time constant to charge said condenser which varies with the value of said equivalent impedence (R), the discharge circuit including a threshold detector discharging the condenser when a predetermined charging level is reaChed and supplying, upon each such discharge, an output pulse to provide a series of pulses which are spaced from each other in dependence on the number of switches (S1-Sn) being closed, to form a measure of the time integral of the heads in operation.
Claim 2
Dependent Claim
202 words
Multiple operating head machine in which each machine head has an individual switch (S1-Sn) indicating, by its position, whether the machine head is running or stopped, said machine having supervisory apparatus comprising a plurality of like individual resistances (RO), one each connected in series with an individual switch (S1-Sn), a switch and a series connected resistance forming a machine head circuit; means connecting the individual machine head circuits all in parallel, whereby the equivalent instantaneous impedance (R) of the parallel circuit will be an indication of the number of operating heads at any instant of time and form a load resistance; a condenser (C), and a charging and discharge circuit therefor connected to said condenser, the charging circuit including said load resistance and having a time constant to charge said condenser which varies with the value of said equivalent impedence (R), the discharge circuit including a threshold detector discharging the condenser when a predetermined charging level is reaChed and supplying, upon each such discharge, an output pulse to provide a series of pulses which are spaced from each other in dependence on the number of switches (S1-Sn) being closed, to form a measure of the time integral of the heads in operation.
Claim 3
Dependent Claim
79 words
Machine according to claim 1 comprising a current generator circuit including a transistor (T1), said equivalent resistance being connected to form the emitter resistance for the transistor (T1) and means (T3) compensating the base-emitter voltage (UBO) to provide a constant emitter voltage (Uo); the condenser (C) being connected in the collector circuit of said transistor (T1) to provide a collector current to charge said condenser which is proportional to the number of closed switches (S1-Sn) forming said equivalent resistance.
Claim 4
Dependent Claim
39 words
The combination of multiple spindle textile spooling machine in the apparatus of claim 2, wherein each spindle forms an operating head and has one of said switches associated therewith, said switch being closed when the spindle is delivering thread.
Claim 5
Dependent Claim
78 words
Machine according to claim 1 including a clock trigger circuit (Um) connected to have the output pulses applied thereto and supplying a predetermined number of trigger pulses (e.g.: 1, 000) per unit time (e.g.: 1 hour) when the pulse rate of the output pulses is a maximum and corresponds to the equivalent resistance indicative of the switches being closed to indicate that all machine heads are operating; and means indicating, per unit time, the number of trigger pulses.
Claim 6
Dependent Claim
49 words
Machine according to claim 4 including timing means indicating elapsed units of operating time; and means (V, 20) comparing the time integral of operating heads, as determined by the number of trigger pulses, with units of elapsed operating time as an indication of operating efficiency of the machine heads.
Claim 7
Dependent Claim
108 words
Machine according to claim 4, wherein said clock trigger circuit comprises a single resistance of fixed value to form a predetermined load resistance; a condenser (C) and a charging and discharge circuit therefor connected to said condenser, the charging circuit including said load resistance and having a predetermined time constant to charge said condenser, as determined by the value of said resistance; the discharge circuit including a threshold detector discharging the condenser when a predetermined charge level is reached and supplying, upon each such discharge, an output pulse, to provide a series of pulses which are spaced from each other in dependence on the value of the resistance.
Claim 8
Dependent Claim
43 words
Machine according to claim 1 wherein said machine is a textile spooling machine and said operating heads are spooling spindles; and wherein said switches are associated with said spindles, the switch of any one spindle being closed when the spindle is delivering thread.
