Title: Memory Protection Circuit
IPC: G06F11/00
Filed: 1967-06-09
Abstract: 1,160,327. Memory protection circuit. RADIO CORPORATION OF AMERICA. 9 June, 1967 [30 June, 1966], No. 26683/67. Heading G4C. A data memory having read and write drive means and gate means providing selective addressing of the memory drive means includes a failure detecting means monitoring the operation of the memory drive means and enabling the gate means to allow the selective addressing only during proper operation of the memory drive means. A combination of memory address signals applied to NOR gates 5, 10 act respectively to energize a write or read driver which applies signals to the memory via transistors 4, 9 respectively. A return path for rewriting the data to a magnetic core memory is provided by a transistor 11. The output signals from the drivers 2, 7 are applied to a failure detector 15 which feeds a Stop flip-flop 16. If a malfunction occurs such as the driver remaining " on " after a read or write cycle the failure detector is triggered. This sets flip-flop 16 to a " one " state, the " one " signal being applied to inhibit a NOR gate 17. If the drivers are operating their output circuits are in a lowvoltage state and cause an input signal to be applied to a NOR gate (27) forming part of the failure detector (Fig. 2, not shown). A second input to the NOR gate is supplied by line 28 and line 14 which indicates correct operation and the presence of a cycle command signal. Since the cycle command signal terminates at the end of a read or write operation the inhibit signal on line 28 is removed at that time. If the voltage state of the driver remains low indicating a fault condition the high output signal from the failure detector switches flipflop 16 to a " 1 " state which thus closes NOR gate 17 to the cycle command signal and prevents any further memory operation. The reset signal to the flip-flop is also inoperative since the failure detector maintains the high signal until the driver is restored to correct operation. Separate failure detectors may be used for each driver.

Title: A method of separating single threads from a warp
IPC: D03J1/14
Filed: 1945-10-12
Abstract: 634,364. Yarns, warping and separating. KOEFOED, HAUBERG, MARSTRAND OG HELWEG AKTIESELSKABET TITAN Oct. 12, 1945, No. 26706. Convention date, May 9, 1944. [Classes 142 (ii) and 142 (iv))] A method of separating single threads from a warp without crossing more than two consecutive threads is characterized in that the threads are separated in two steps in such a manner that in the first step a separating member engages a single thread, or at the most two threads, at the edge of the warp, the thread or threads being moved to an inactive position at some distance from the edge of the warp, and another separating member for carrying out the second step engages the inactive thread, or one of these threads, and moves it to other members for subsequent treatment, e.g. threading through a heddle or tying to a thread of another warp, the tension of the thread or threads in the inactive position preventing further threads being transferred to that position until the thread or threads already in that position have been removed. In the device shown, a separating member 8 which has a circular motion imparted thereto by means of a crank 10 and a movable member 12, 13 engages threads 1, 2 at the edge of the warp and moves them to an inactive position where they are held by a spring-actuated. hooked member 15 formed with a catch 19 which, due to the tension of the threads 1, 2 in the inactive position, locks an arm 20 provided on the movable member 12, 13 thus preventing the member 8 from transferring further threads to the inactive position until the threads already in that position have been removed by means of a vertically movable separating member 21. In a modified device, the thread or threads separated by the separating member operating in the first step, is or are engaged by a spring-pressed oscillatory hooked member and moved to be engaged by a fixed hooked member in the inactive position, the tension of the separated thread or threads preventing the oscillatory hooked member from transferring further threads to the fixed hooked member until the thread or threads already held by the latter have been removed by a separating member operating in the second step.

[Classes 38 (ii) and 38 (iv)] [Also in Group XXXVII] In a control apparatus for varying the current supplied to a load (e.g. the primary of a welding transformer), " coarse " control is effected by tappings on a choke winding and " fine '' control by variation of an air gap in the choke core. In light work the contact arm 12 is initially placed on stud M so that the whole of the choke winding 4 is in series with the load 23 and variation of current through the load is obtained by movement of the arm over the contact set 19 and by variations in the air gap 5A. In heavy work, the contact arm is placed on any selected pair of the contact set 20, e.g. those connected to tappings d, e. The current from line L1 divides at tapping a flowing from a to d and from e to d, i.e. opposite directions, thereby decreasing the choke inductance and increasing the load current. The choke inductance is varied according to the selection of a pair of contacts in set 20, thus varying the lengths of the choke winding 4 placed in parallel. The system can be adapted for use on a supply of any number of phases and may be constructed in an oil-filled tank.
