Title: Machine for covering a core element by winding
IPC: D02G3/36
Filed: 1971-12-03
Abstract: 1343503 Covering cores by winding M WALTER 3 Dec 1971 [11 Dec 1970] 56255/71 Heading B8G A machine for covering a travelling core A by winding layers of thread or ribbon thereon comprises a first annular flange plate C carrying, on the side facing downstream, reels El, E2 of the covering material ; and a second annular flange plate D carrying, on the side facing upstream, reels F1, F2 of the covering material. Mounted upstream of the plate D is a first annular member L and mounted downstream of the plate C is a second annular member L, there being means for driving the annular members in the opposite direction to that in which the associated flange plates are rotated. The annular members L carry means to which the ribbons or threads can be initially attached, said means serving subsequently to sever the thread. Mode of operation:- Whilst the plate C is rotating to wind thread or ribbon G1, G2 on to the core A moving in direction B, the threads or ribbons J1, J2 from the reels F1, F2 are secured to hooks on the associated annular member L. When the reels E1, E2 are nearly exhausted the annular plate D and its annular member L are brought up to speed. Thereafter the speed of the annular member L associated with the reels F1, F2 is retarded relatively to the speed of the annular plate D to cause progressive tension in the threads or ribbons J1, J2 and to bring them into eventual contact with the body being wound. When this takes place the threads or ribbons are wound on to the body A and the hooks on the annular member L sever their connection with the thread or ribbon. The rotation of the annular plate C is halted and fresh supply reels E1, E2 are placed thereon, the new threads or ribbons G1, G2 being attached to the hooks on the associated annular member L. When the reels F1, F2 are nearly exhausted the annular plate C and associated annular member L are brought up to speed and the speed of the annular member L is then retarded. This causes the new threads or ribbons G1, G2 to be brought into contact with the body A and winding on to the body A commences, the hooks on the annular member L serving then to sever their connection with the threads or ribbons G1, G2. The core covering operation is thus a continuous one there being no need to stop the operation when the reels on either of the annular plates C, D are exhausted.

Abstract: 1318490 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 13 Dec 1971 [29 Dec 1970 (2)] 57708/71 Heading G4H [Also in Division H4] Apparatus for deriving, from an input train of coded signals representing a text prepared in conformity with a first format, a revised train of coded signals representing the text after having been revised to conform to a revised format, comprises means for registering an input scale of stops which relate the text to the first format and a revised scale of stops which relate the text to the revised format, means for sensing each occurrence of a predetermined code in the input train and for providing, by reference to the input scale, an indication of a corresponding stop in the first format, and means for converting each such indication, by reference to the revised scale of stops, into a revised indication of a corresponding stop in the revised format and for inserting the revised indication into the input train. As disclosed, the predetermined code is a tabulation code, the input train coming from magnetic card or a keyboard into a processor and after conversion there to the revised format being recorded on to magnetic card for subsequent control of a typewriter. The two formats may differ in the escapement pitch, and columnar and tabulation requirements. The stops referred to are tab stops. Both scales can be displayed on a CRT display, together with text in the revised format, indicators for left and right line margins (i.e. boundaries) and paragraph beginnings, a text cursor, a tab cursor (associated with the scale displayed) and a pitch indicator. This pitch indicator permits the pitch to be changed by pressing a button repetitively until the pitch indicator has cycled to the required pitch. The input scale including its tab stop can be set up by the operator using keyboard buttons and the display (including its cursor facility, the cursors being stepped under control of some of the buttons). The system automatically sets tab stops in the output scale at inch positions corresponding (as near as possible) to the tab stops in the input scale. The left and right line margins are also set by the operator, the processor holding, for each line of the display, a word specifying the number of characters in the displayed line, the left margin setting, the line length allowed for characters on the line, and whether the line is associated with a paragraph beginning. Such alteration of the margins causes automatic consequential adjustment of the line contents. If a change of pitch causes tab positions (stops) to be overrun (i.e. the sequence of characters which is supposed to fall between two stops is now too long for this), the overrun position is flagged in the train of signals and an overrun character is displayed on the CRT. The operator can then move either of the adjacent columns under keyboard control to make room, using the text cursor. The operator can order justification to take place.

Abstract: 1403479 Automatic Control of Position INTERNATIONAL BUSINESS MACHINES CORP 19 Dec 1973 [27 Dec 1972 (2)] 58795/73 Heading G3N [Also in Division H2 ] Apparatus for controlling the position of a body, preferably the rotor of a stepping motor, moving into a desired position comprise, first and second driving means for supplying driving energy to the body in first and opposite directions respectively, means for initiating operation of the second driving means when the body has moved through the desired position in the first direction, means for subsequently initiating operation of the first driving means when the body is returning towards the desired position in the opposite direction, and means, for subsequently interrupting the operation of the second driving means before the body reaches the desired position. The control is generally digital and the desired position is loaded into a register for comparison with the count stored in a counter fed with pulses produced by a device indicative of rotation of the rotor. These pulses together with a pulse emitted when desired and actual positions coincide control operation of the apparatus. An overshot counter is enabled for the the rotor has passed the desired position for the first time and counts the emitted pulses with regard to the direction of movement of the rotor. A divide-by-two counter also counts the same input pulses as the overshoot counter and the two counts are compared, switch pulses being produced when equality is achieved. The switch pulse causes initiation of the first driving means and by this arrangement this initiation takes place when the rotor is approximately half-way between the desired position and its furthest from the desired position. Furthermore, the second driving means is not interrupted until the rotor has moved one movement further back towards the desired position. A fine positioning system is activated when the rotor moves through the desired position for the second time whereby an analog controller supplies the driving means with voltage dependent upon the distance from the desired position.
