Title: Microprogramme controller for data processor
IPC: G11C17/00
Filed: 1973-12-13
Abstract: 1457878 Microprogram controllers GENERAL ELECTRIC CO 13 Dec 1973 [14 Dec 1972] 57732/73 Heading G4A The addressing system 22b-22d of a microinstruction memory MPROM receives address and control data both from the memory MPROM and from a microprogram decode memory MDROM which stores at each location a word which is unique to each different type of program instruction and which is addressed by the instruction OP code. Memory MPROM is addressed by a counter 22d which may be incremented or may be parallel loaded from an address field of a word read from MDROM or a microinstruction read from MPROM. Each MDROM word, also includes a field specifying the memory location of an index value and an ALU function select field. There are three types of microinstruction, branch, procedure and I/O. The branch microinstructions have a bit test field specifying conditions to be met for the branch to be taken, a branch address in MPROM and a bit which when set specifies that the branch address is to be taken from the currently addressed MDROM word, e.g. for an unconditional branch to the start of a microprogram execution subroutine appropriate to the present program instruction. The procedure microinstructions include an ALU function select field, control bits which determine the operations of A and K registers of the ALU and of the instruction address register IAR. A further bit is used for resetting address counter MPCNT. The I/O microinstructions control transfer of data between a specified source and destination, e.g. between a store address given by a specified register and another register. The microinstructions are arranged in subroutines, extending over sets of sequential MPROM addresses, to perform address calculation (base-relative and indexed), instruction and operand fetch and execution (e.g. add/subtract, shift and branch on status) operations.

Patent GB-606900-A (GB)
Abstract: 606,900. Workmen's time recorders. LANDIS & GYR SOC. ANON. Aug. 8, 1945, No. 20265. Convention date, Aug. 18, 1944. [Class 106 (iv)] Stamping apparatus for workmen's time record cards is characterised in that the card guide serves to release the stamping mechanism. A card guide slidably and rotatably mounted on a shaft 6 is shifted laterally with respect to a printing mechanism 8 by known clockwork means through a crank 7 in accordance with regular working times, corresponding to which there are notches in a fixed bar 24 co-operating with a lever 23 pivoted to the card guide with a lifting rail 26 controlled through a rod 27 by the clockwork means. The weight of a card inserted in the guide 2 depresses a feeler 29 to rotate a double armed lever 31, 32 against a spring 40 which normally holds the bottom of a slot 42 against a pin 41 in a slide 34 mounted on the card guide and controlled in accordance with the day of the week by known clockwork means through a rod 35. Rotation of the lever 32 disengages a part 36 from behind an arm 37 which, being guided by a fixed rod 39 and rotatably but not slidably mounted on a tube 38 surrounding the shaft 6 and fixed to the card guide, remains in a vertical plane and when, engaged by the part 36, prevents the forward rocking of the card guide. However, when the card is inserted and removes the restraint the forward rocking of the card guide disengages a pawl 18 from a rail 17 to release a striking member 12 under the action of a spring 16. After the stamping a spring 19, stronger than the spring 16, restores the card guide to its mean position in contact with a spring 20, stronger than the spring 19, whose forward action is limited by a stop 22, pressing the striking member 12 back under the tension of the spring 16 till the pawl 18 again latches over the rail 17. To stamp a card at an intermediate time not automatically set, the card guide is pressed back against a spring 20 till a ramp 25 on the lever 23 rides up over the rail 26 to disengage the notch bar when the card guide can be moved to the appropriate time setting as indicated by a pointer 50. Ink ribbon feed. The tube 38 is guided by a slot 43 and pin 44 inserted in the shaft 6 upon which is fixed a lever 45 carrying a pawl 46 engaging a ratchet-wheel 47 which may be used for feeding an ink ribbon 10 past the printing mechanism 8 and for winding the driving spring.
