IPC: E06B3/22
Filed: 1971-07-20

Title: Digital computer simulation system
IPC: G06F11/22
Filed: 1970-07-14
Abstract: 1,271,595. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 July, 1970 [24 July, 1969], No. 34041/70. Heading H4K. [Also in Divisions G4-G6] A simulation system comprises one or more digital computers CPa, CPb having a program to be tested and a digital simulation computer CPd programmed to simulate peripheral units in activity wherein the computers CPa, CPb can be driven by the clock pulses MCX of computer CPd. This ensures that the simulation computer can operate at the same speed as the test computers while testing their programmes which is difficult to ensure if computers CPa, CPb are controlled by their own clock sources. Simulation.-The programme(s) to be tested are loaded into the or each computer CPa, CPb and a simulation programme is loaded into the computer CPd, which simulation programme sends data representing peripheral units in activity, e.g. for a telephone exchange system in real time, to the computer(s) CPa, CPb, receives output data from the computer(s) CPa, CPb, checks its correctness and sends further data. The computer CPd usually prints all the data.  Operation.-The computer CPd is controlled by clock pulses MCX which are also sent to an AND gate pt controlled by a bi-stable MA. When gate pt is enabled it sends clock pulses CK to AND gates pb, pc controlled by respective bi-stables MB, MC, and, if these are enabled, clock pulses are sent to control the computers CPa, CPb whose own clock sources HGa, HGb are cut off for the period of the simulation by switches ca, cb. The bi-stable MA can be set to 0, hence interrupting the computers CPa, CPb, by the computer CPd, by detectors DT and DS, or a counter CIG. The counter CIG can cause interrupt after a predetermined count (of clock pulses) set by computer CPd. Detector DT causes interrupt when either computer CPa, CPb provides an input/output and detector DS causes interrupt in case either computer itself has an internal interrupt. The bi-stables MB, MC are set by computer CPd so that one of the computers CPa, CPb can be interrupted while the other continues operation.

Title: Stamp feeding and affixing device
IPC: B65C11/04
Filed: 1962-09-07
Abstract: 1,012,140. Stamp affixing machine. STAMPLICATOR Inc. Sept. 7, 1962 [Oct. 9, 1961], No. 34352/62. Heading B8F.  A stamp feeding and severing machine comprises an actuating arm 4 pivotally mounted at 17 to a base 1 and containing a stamp supply and feeding device 6, a cut-off device 10 and a pad 14 for pressing the stamp against an envelope. The arm 4 contains a reel 5 of stamps, separated by perforated lines, resting on a threaded stud 30 with a strip of stamps 5a curved downwardly to impart rigidity to the stamp passing through the feed and guide mechanism 6 and the cutting mechanism 10 to emerge below the pressing pad 79. The base 1 contains a reservoir 83 containing bristles in a container 88 which carry water up to the brush 87. The envelope is passed between the bristles and the brush and the portion to which the stamp is applied is wetted. The cutting mechanism 10 comprises a blade 70 having flanged edges 71 slidably fitted in a guide block. A portion of the blade emerges beneath the guide block and contains a gap 75 through which the stamp strip 5a passes and which forms the cutting edges 76. Fixed in the guide block is a shear plate 77 having a shearing edge 78 which co-operates with the edges 76 to cut the stamp along its perforations. When the actuating arm 4 is pressed towards the base 1 the cutting blade 70 is brought into contact with the base and pressed upwards against the action of spring 72. This causes the stamp to be cut and pressed against the wet envelope by the pad 79 mounted at an angle to the base such that when the stamp is applied to the envelope and the pad is brought parallel to the base the stamp is moved slightly to cause better adhesion. In a modification to the cutting mechanism (Fig. 20) the presser pad and cutter are mounted on a mounting plate 110 secured to the arm 4. The shear blade 115 is urged outwardly by spring 116 and operates as previously described, the stamp being cut between edges 113 and 114. Feed mechanism. When the arm is allowed to return to its original position (Fig. 4) under the action of spring 16, the stamp feed mechanism advances the stamps. Fingers 54 (Fig. 14) engaging in the stamp perforations are attached by block 51 to a lever 61 which passes through a slot 65 (Fig. 4) in the arm case and is secured to a rod 64 secured to the base 1. When the arm 4 is depressed, the block 51 is retained in the same position with respect to the rod 64 while the arm and stamps are moved forwardly  and downwardly. Thus the block 51 appears to move backward with respect to the arm 4. When the arm 4 is released and springs back the fingers 54 engage in the stamp perforations and move the stamp forward one position with respect to the arm. The machine can apply perforated labels.

The motion has a steady component and a vibratory one. As shown, the arrangement is duplicated at each end of the mould. Each worm 67 is driven by an hydraulic motor 70 in response to the difference between a pressure transducer 25 (i.e. for compressive force) with an electrical output and a ramp signal generated at 21. The second, hydraulic, drive 12 is controlled by the difference between a displacement transducer 14 and a waveform generated (in respect of magnitude, frequency and shape) at 22 ... 24. 19 and 45 are electrical and hydraulic power supplies respectively. In Fig. 1 (not shown), which is not an embodiment of the invention, there is an additional displacement transducer for movement of the hydraulic valve 12, which in this case drives the sleeve directly. Fig. 2 (not shown) illustrates a machine complete with weight controlled filling hoppers; moulds are filled and then transferred to the compression station, which is surrounded by a suction box (130) to remove gases evolved during compression.
