Title: Improvements in or relating to arrangements for metering telephone calls
Inventor: GREENAWAY JOHN FRANK
IPC: H04M15/04
Filed: 1957-03-12
Abstract: 876,538. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Feb. 12, 1958 [March 12, 1957], No. 8052/57. Class 40 (4). A digit indicative of the duration between metering pulses appropriate to the call is entered in a register on a magnetic drum. The digit is translated into a larger number which is entered in another part of the register and is then reduced by one at each rotation of the drum. When the number is exhausted a metering pulse is sent to line and the cycle repeats. Two embodiments are described. First embodiment, Figs. 2 and 3. Registers on the drum, of the type described in Specification 717,687, are allotted to trunk relay sets as described in Specification 831,188. The register allotted to a call detects a train of impulses PIA from the common translator. This train represents the meter digit and by repeated operation of electronic relay MAN is entered in block TYI of the register. When the called subscriber answers MAA is set and remains set if the apparatus is functioning correctly. MBA is then set during the same scan to return a metering impulse POM to the calling subscriber's meter over gate 12. MBA enables the meter digit to block TYI to set up electronic relays MCA-MFA according to the binary code. The outputs of these relays are translated (Fig. 4, not shown) to enter a corresponding number in the 11 elements of timing blocks TY2, TY3. At the end of the scan MBAMFA are restored. Also when the called subscriber answers electronic relay MGA is set whereby gates 20, 21 reduce by one at each scan the number entered in timing blocks TY2, TY3. When this number is reduced to zero MBA is again set to return another metering pulse and the cycle begins again. At the end of the call MHA is set and the register is cleared. Second embodiment, Figs. 5, 6. The apparatus functions in the manner described above except that translation of the meter code digit is effected by reference to five sections on three library tracks on the drum. The meter code digit is read simultaneously with all possible code digits permanently recorded on the library sections and the translation digits on the library sections are read at the same time as the corresponding elements of the timing blocks TY2. TY3 of the meter register are being scanned. Output from each of the library reading heads is controlled by an associated relay MG1-MG15. When the called subscriber answers, MAA, MCA set MBA, Fig. 6, MBA sets all the library gating relays MG1-MG15. The codes in the library sections are compared with the meter code in the register by gates 33 and 34 and discrepancy results in the related relay MG1-MG15 being restored, only that one corresponding to the meter code remaining set. During the scan of the remaining blocks of the library section the required translation is entered into the timing blocks by gates 35, 36. MBA sends out a metering pulse when first operated and again when the timing blocks have been zeroized, when the cycle begins again.

Filed: 1955-03-23
Abstract: 779,029. Knitting-machines. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES. March 23, 1955 [June 16, 1954], No. 8433/55. Class 74 (2). To reduce the speed of the friction bar of a straight-bar machine during the knitting of the heel, the draw bar 2 driven from the draw lever transmits its motion to the friction bar through a lever 4 and member 9 connected to the friction bar. The end of the lever 4 is pivoted at 5 on nuts 6 screwed on to spindles 7, 7<SP>1</SP>. A slide block on a stud 3 secured to the draw bar 2 engages between guide ribs 4<SP>1</SP> on the lever 4 and a similar slide block secured by a stud 8 to the upper end of the lever 4 engages between guide ribs 9<SP>1</SP> on the member 9. Rotation of the screws 7, 7<SP>1</SP> moves the lever to vary the distance between pivot 5 and slide block on stud 3 and to vary the distance between the slide block on stud 3 and slide block on stud 8, the slide blocks sliding in their respective guides on the lever 4 and member 9. As the pivot point 5 moves away from the slide block on the bar 2 when the lever 4 is lowered, the slide block engaging member 9 moves nearer to the slide block on bar 2 and the speed and traverse of the member 9 and the friction bar is reduced. Alternatively, the spindles may be aligned horizontally and links may connect the nuts to the pivot 5 on the lever 4. In either arrangement, only one screw-threaded spindle need be provided, the other spindle acting as a guide for a slide member which is coupled to the lever in the same manner as the nut it replaces.

Abstract: 816,171. Selecting threads from an end- and-end lease. WOOL INDUSTRIES RESEARCH ASSOCIATION. June 24, 1955 [March 24, 1954], No. 8547/54. Class 142(1) Yarns arranged in an end-and-end lease are selected by two mechanisms 9 (only one mechanism is shown in Fig. 1) reciprocating above and to each side of the line x of the lease and by a secondary machanism 34 positioned at a distance from one lease rod along the warp threads. When one mechanism 9 advances, a stop piece 18 (Fig. 2) restrains threads a1, a2, a3 and a thread a previously selected is being drawn back by the other, receding, mechanism 9. On further forward movement of the first mechanism 9, yarns a2, a3 are engaged by a recess 2 in a part 1, the stop piece 18 is lifted, and yarn a1 springs back towards a member 5. A part 3 is swung down by a roller 17 engaging a cam 16 and the parts 1 and 3 are latched together. The mechanism 9 now recedes and the yarn a1 is moved by a barb 4 on the part 3 towards a barb 7. The yarn a previously selected is moved back from barb 7 to barb 8 by a notch 6 on the part 1. The secondary mechanism 34 moves downwards and rearwards and also moves the yarn a at a point further from the lease crossing x. When the mechanism 9 reaches its rearmost position an edge 14 on part 1 engages a member 15 and part 1 is disengaged from part 3 and a spring 11. retracts the parts 1 and 3. The mechanisms 9 are reciprocated by arms 47 and cams 46 on a rotating shaft 23. The lower ends of the arms engage lugs 28 on the mechanisms 9. A further cam 38 on the shaft 23 moves the secondary mechanism 34 downwardly and rearwardly. The mechanisms 9 reciprocate on rods 25 mounted in a block 29 and rollers 31 carried by a framework 30 engage the lease rods and thereby locate the warp threads vertically.
