Title: A digital electronic computer system
IPC: G06F9/46
Filed: 1966-03-31
Abstract: 1,097,449. Data processor. RADIO CORPORATION OF AMERICA. March 31, 1966 [April 16, 1965], No. 14240/66. Heading G4A. A digital electric data processor includes instruction execution registers 12 incorporating an operation code register OP, a plurality of sets of programme execution registers I, II, III, IV providing means for computer operation in any one of a corresponding plurality of different processor states, a processor state control register 30 to enable outputs to, and from, any selected one of the programme execution registers, a decoder coupled to the operation code register to detect privileged or prohibited instructions, gate means 54-57 responsive to the output of the decoder and to a prohibit bit in a register 61-64 in the energized one of the programme execution registers, and means responsive to the output of said gate means to change the contents of the processor state control register. In operation the computer is normally executing the user's instructions and is in state I, the processor state control register 30 and a " 1 out of n " decoder 34 passing an enabling signal on line 361. If, for instance, an " add " instruction occurs in the OP register, the operand address in register AR is used to fetch the operand in memory 6 and place it in a utility register UR. Thereafter the operand is applied to a logic arithmetic unit 15. At the same time the other operand located in a programme execution register in set I is also applied to the logic arithmetic unit. The resulting sum is then applied to a further register in set I in case it is required later in the programme. The sequential execution of the user's programme continues until a switch to another programme occurs. This may be caused by an interrupt such as machine error, request for service of an input-output device, data error &c., or by signals from a control unit 20. The new data is entered in processor state control register 30 which produces an enabling signal on a different line 36. Thus a new programme may be obtained without unloading the data in set 1 of the register into store and loading them with the new programme. The new execution occurs until a switch to a further or the original programme is required. Some instructions can only be executed with the computer in a particular one of its states. These are called privileged instructions and are first decoded by privileged instruction decoder 58 which then enables one, or some or all of the AND gates 54-57. A second input to the gates comes from the one of flip-flops 61-64 which is in the enabled set of registers I-IV. If the computer is in a state such that the new instruction cannot be processed then the AND gate is enabled to cause an interruption and a switch to a new processor state. If the instruction can be processed the AND gate is inhibited. For ease in working one of the registers II-IV3 may be used by more than one set I-IV. For instance (Fig. 3, not shown) register 13 may be connected to the input and output gates of set I and set II to secure transferring the same data from I3 to II3.

Title: Winding rolls of tape
IPC: B65H18/16
Filed: 1961-04-20
Abstract: 929,069. Winding fabrics. JOHNSON & JOHNSON. April 20, 1961 [April 20, 1960], No. 14350/61. Class 42 (2). A method of winding a plurality of strips of pressure-sensitive adhesive tape on a mandrel 50 comprises positioning the strips with their adhesive faces 12b towards the mandrel and winding the tape upon the mandrel while pressing the edges of the strips inwardly toward the mandrel to a position below the level of the tape extending between these edges. A pressure sensitive adhesive sheet 12 is fed from a supply roll 11 over a silicone-coated guide roll 17 and under a driven, metal anvil roll 18, the rolls 17, 18 being in driving connection. The sheet 12 is cut into strips by circular knives 34 each mounted at one of a pivoted lever 35 and normallyurged into contact with the roll 18 by a tension spring 38. The knives 34 can be depressed from the roll 18 by rotating a cam 42 by a handle 44 to raise the other ends of the levers 35. After slitting, the tape 46 passes over a rubber roll 47 to a roll 48 which is provided with depresser rings 49 to act on the edges of the strips. The roll 48 is driven by the roll 18 through a chain 26, a variable drive unit 29 and a chain 54a so that the peripheral speed of the rings 49 is equal to the peripheral speed of the roll 18. Four mandrels 50 are each mounted in a slot 65 in an arm 66 rotatably mounted by a pin 67 to a plate 61 fixed to a shaft 62 which can be rotated by a hand wheel 64 (Fig. 2, not shown). Each arm 66 is urged against a stop 68 by a spring 69 acting between the arm and a shoulder 72 on a sleeve 71 secured to the shaft 62. The mandrels 50 may be expandable either mechanically or by air pressure or may be knurled to receive cores 74, Fig. 5, on which the tape is to be wound and preferably having relieved edges 75. In operation, the strips are wound on the mandrel 50 positioned above the roll 48 and which is urged by the spring 69 into contact therewith to be driven thereby. The rings 49 contact the edge portions 77 of the strips and depress them, as shown in Fig. 5, so that adhesive edges of adjacent rolls do not contact one another. When the desired amount of tape is wound on a mandrel the rolls 18, 48 are stopped and the hand wheel operated to position the next mandrel above the roll 48. A spring- loaded detent 81 engages a recess 84 to hold the plate 61 in position. The tape is severed by an oscillatable knife blade 85. In a modification, the plate 61 is rotated automatically after a predetermined length of tape has been wound. In a further non-automatic modification, only two mandrels 50 are provided.
