Title: Testing logic networks
IPC: G01R31/28
Filed: 1975-04-17
Abstract: 1478438 Testing electrical circuits INTERNATIONAL BUSINESS MACHINES CORP 17 April 1975 [8 May 1974] 15772/75 Heading G1U A method of testing logic networks which include a plurality of blocks having inputs and outputs inaccessible to test equipment includes simulating the logic network under test, applying a binary test pattern to the simulated network, determining whether that pattern will indicate a fault at a particular point in the network, determining what successive changes to the input pattern will propagate the binary value at the particular point to an accessible output of the network, applying the successive test patterns to the actual network and comparing the outputs of the actual and simulated networks. The central processing unit 20, Fig. 2, uses the description of the network under test stored in memory 11 to generate a list of faults which may occur in the network. By selecting a particular fault, and performing a backtracing programme, Fig. 15 (not shown) a series of input test patterns may be generated which propagate the fault to an accessible output of the network. The test evaluator 700 determines whether the output arrived at is capable of uniquely determining the particular fault. If it is, the test pattern series is applied also to the network under test and its outputs compared to the simulator outputs. The comparison results are fed back to the central processing unit 20 and stored for later printout. The simulator is controlled to compare the network under test with all outputs generated by patterns identifying all the faults in the computer list. The Specification contains detailed logic circuits embodying the various parts of the system, as well as flow diagrams indicating the backtracing, fault analyzing and test pattern generation.

Title: Improvements in or relating to machines for the manufacture of button and string-closures and attaching same to containers, wrappers, and the like
IPC: B65D27/24
Filed: 1920-06-10
Abstract: 144,711. Trenchard, H. Dec. 30, 1915, [Convention date]. Setting-eyelets.-Relates to machines for making " button - and - string " fastenings and attaching them to envelopes, boxes, &c., such fastenings comprising pairs of washers 52, 53 and 55, 56 secured by eyelets 57 to the envelope &c., with a length of string 58 attached to one pair of washers, as shown in Fig. 12. According to the invention, mechanism for setting an eyelet is combined with mechanism for automatically looping the string in position to be fastened by the eyelet, and with means for severing a length of string after it has been attached. The machine comprises two plungers 1, 2 operated from a main shaft 3 and adapted to be brought together once for each revolution of the shaft. A slidable spring-pressed pin 4 is mounted in the plunger 2, and in the operation of the machine a fastening washer and eyelet are placed upon the pin 4 whilst a reiuforcing washer is placed upon the plunger 1. The string is wound upon a pin 4, before the plungers come together, by a device comprising a hollow wheel 6 through which the plunger 2 can pass, the wheel being so geared to the main shaft 3 as to rotate at a greater speed. A U- shaped piece 10 passing through the wheel 6 is adapted to grasp the end of the string against the face of the wheel, the part 10 being thrust out against the action of springs to receive the string, and then freed so as to grasp the string, by the action of the end of a lever 15 on a cam 12 to which the member 10 is attached. The lever 15 is operated by a cam 16 on the shaft 3. The string is fed to the looping-device by a reciprocating member 17 carrying a finger 18 with a resilient side plate 19 to engage the string. The part 17 is moved between guides 20 by a. crank and link 21, 22, geared to the main shaft by a train 24 - - 28. When the string has been looped around the pin 4, and the string-carrying member 27 has receded to the bottom end of the guides, the string is severed by shears 29. The shears are mounted on a spring-controlled oscillating member 32 pivoted at 33, and comprise fixed and movable blades 30, 31. When a cam 36 on the member 32 is engaged by a roller 37 on the string- carrier 17, the shears are moved forward through an aperture in the guideway and cut the string, and are afterwards retracted by the spring 38. The movable blade 31 is actuated, to close and open the shears, by fixed cams 42, 43 respectively, Fig. 9.

Title: Attitude indicator
IPC: G01C23/00
Filed: 1969-03-27
Abstract: 1,224,825. Gyroscopic apparatus. AVIATION INSTRUMENT MFG. CORP. March 27, 1969 [May 29, 1968], No.16039/69. Heading G1C. An attitude instrument for an aircraft comprises a terrain reference 30 including a horizon line 32 fixed in position parallel to the transverse axis of the aircraft, an aircraft simulator 40, a gyroscope 60 for maintaining a stabilized reference direction in space and coupling means between the simulator and the gyroscope for indicating roll and pitch attitudes of the aircraft. The gyroscope, which is electrically driven is mounted in agimbal assembly 65 to one end of which is secured a gear 71. The gear 71 is coupled to a gear 73 by a spur gear 72. The simulator is supported by an arm 50 each end of which is pivotally mounted in a bearing block 101, 102 fixed to the gear 73. One end of the arm 50 is divided into legs 104, 105 between which a ball 107 is attached by a mounting 106. The ball engages a slot 110 in a gear 87 coupled to a gear 81 via a gear train 83, 85, 86, 88. If the aircraft rolls the gimbal 65 and the gear 71 remain fixed in space but relative to the instrument case, the gear 71 rotates thus rotating the gears 72, 73 so that the simulator 40 tilts with respect to the horizon line 32 to indicate the roll of the aircraft. Assuming the aircraft does not pitch, gears 81, 83 do not rotate, thus causing the gear 85 to rotate the gear 87 by the same amount that the gear 73 has rotated. The ball 107 remains in the slot 110 and no pivoting of the arm 50 occurs. However, if the aircraft pitches, the gear 81 rotates the gear 87 relative to the gear 73 and the ball 107 engages the leg 104 or 105 to pivot the simulator downwardly or upwardly. At a predetermined maximum pitch indicating angle the ball 107 pivots out of the slot preventing any further movement of the arm 50. On returning to level flight a pin 111 or 112 contacts the leg 104 or 105 to return the arm 50 to its level position. A zero adjustment for aligning the simulator on the horizon line 32 is provided by an external knob which adjusts the position of the gear 87 by a slight movement of the gear 88 on its support 89. In a modification, a three dimensional simulator is described.
