Filed: 1974-10-31
Abstract: 1480789 Magnetic bubble systems MONSANTO CO 31 Oct 1974 [11 Jan 1974] 47147/74 Heading H3B In a bubble propagation system having two paths defined by a ferromagnetic overlay, a pulsed magnetic drive field contains vector sequences exclusive to the respective paths. One path consists of a continuous permalloy "zig-zag" 34, 36, Fig. 2, along which bubbles are propagated by successive application of drive field vectors 1, 2 parallel to the limbs 34, 36. Three such paths forming an equilateral triangle Fig. 3 are operated by vectors 1, 2, 3 in that order to drive bubbles clockwise. For any one side 44, 46, 48 only two vectors are effective since the third is not parallel to a limb and has insufficient component in that direction to ensure saturation. This may be enhanced by selecting a permalloy of appropriate hysteresis property or by ensuring that the limbs have a natural magnetization across their width. Coupler re-entrant polygons based on the zigzag and triangle pattern may be employed on one chip and closed paths at different orientations are respectively driven by interlaced pulse fields parallel to their respective paths and operating in opposite senses.

Title: Data processing
IPC: G06F11/00
Filed: 1970-10-06
Abstract: 1326939 Data processing WESTERN ELECTRIC CO Inc 6 Oct 1970 [6 Oct 1969] 47390/70 Heading G4A A data processing system includes a number of stores 300-0, 300-n addressed over a common bus by a central processor and is arranged, on detection of an erroneous response over the bus resulting from addressing a predetermined location in an addressed store, each store containing at the predetermined location a unique identifying word, and to analyse the response to determine whether more than one identifying word has been received and thus whether more than one store is responding to the addressing. As described two central processors 200-1, and 200-2, e.g. as described in Specification 1,129,660, are provided, each being associated with a respective bus, BUS 0, and BUS 1. Corresponding stores on the respective buses contain identical data and are assigned the same identification word which consists of a single binary '1' in a field of '0's. Normally one of the processors is 'on line', e.g. controlling a telephone switching network, and the other is off-line. The stores-300 are of the magnetic twister type, each having a capacity of 2<SP>14</SP> words each of which includes 40 data bits and 7 error check bits. The bus contains conductors 331 which provide a 4-bit OP code designating read, write etc. operations, 341 which provide the 40 data and 7 check bits, 351 which provide a 5 bit store identification code, and 361 which provide 14 bit addresses. Each store is assigned its unique 5-bit code by means of a permanent store 303, the received 5-bit word being compared with the wired in address in circuit 302. A match sets flip-flop 305 and enables gate 306 allowing the selected store to be addressed. The 5-bit word received by the store may be immediately retransmitted via gate 320 and register 311 for verification. Error checking operations-If data accessed from the store fails any error checks a wired in interrupt device stops the off line processor and initiates a fault recognition sequence which is stored in one of the stores 300. To ensure that the sequence is not executed from a failed store the processors switch buses except where the duplicate store containing the fault recognition sequence has previously been disconnected when no recovery is possible. The on-line processor then sets a binary '1' in a register at a position corresponding to the '1' in the identifying word of the addressed store. The identifying word of the addressed store is then accessed and exclusive-OR masked with the contents of the register. Any remaining '1' bit thus identifies a suspect store which is disconnected. The disconnection is achieved by resetting 'Port' flipflop 312 to block AND 313 and prevent the store transmitting data. The process is then repeated and if the masked word is not all binary '0's the addressed store is assumed to be faulty. The Specification sets out a fault recognition program in some detail and states that it may be used as a part of a larger testing program executed either in response to faults or as preventive maintenance.

A cartridge ramming device for introducing cartridges into the breech of an automatic gun comprises a rammer member 2 having a ramming dent 1 pivoted at 15 thereto and biased by a spring 18 into an active position (as shown) wherein it engages the base of a cartridge to feed it into the breech on forward movement of the member 2. A cam 20 pivoted on a shaft 21 on which is also pivoted rammer dent actuating means 24 controls the positioning of the dent 1. The parts are in the position shown on forward movement of the member 2 so that the dent 1 can engage a cartridge. An abutment 29 is provided on the gun and the lever 24 rides over this on forward movement, being displaced through an angle less than that required to move the dent from the active position. However, on the return movement of the member 2 the lever 24 is caught by the abutment 29 and is rotated about pivot 21 to cause cam 20 to rotate and pivot the dent upwardly into an inactive position wherein it is clear of the path taken by an ejected cartridge case. The latter when it has passed the dent 1 actuates the lever 24 to return it to a position wherein cam 20 permits the spring 18 to return the dent 1 into the active position ready for the next forward movement. The member 2 in the form of a trolley is guided by wheels 3 engaging in grooves 4 in a reciprocating rammer member 8. The latter has pulleys 9 over which pass a chain 10 secured to a stationary lug 12 of the gun and the trolley 2 so that as the member 8 reciprocates under the action of piston motor 5 the trolley 2 will also reciprocate but at twice the speed.
