Title: Electric bistable device
IPC: H03K17/84
Filed: 1960-11-18
Abstract: 930,119. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1960 [Dec. 2, 1959], No. 39678/60. Class 40 (9). [Also in Groups XIX and XL (c)] Shift registers have stages each comprising a combination of a tunnel diode and a saturable reactor or bi-stable magnetic core, at least one element of the combination having two stable states of operation. Fig. 2 shows a unidirectional shift register having a D.C. source 22 and a shift pulse source 23. (a) C 1  to C 4  are bi-stable cores; E 1  to E 4  diodes used with loadline 12 (Fig. 1) i.e. two stable states. Initially cores are at negative saturation and diodes in state P. Winding 21 is energized to switch C 3  to positive saturation. The voltage in winding 18 increases current through E 3 . Switching C 3  causes switching of E 2  to state Q. Most of the current through E 3  now passes through winding 18. A shift pulse sending C 3  to negative saturation increases current through Eg switching it to state Q. E 2  switches to point P via point S. As Eg seeks state Q current through E 4  (state P) shunted through winding 18 of C 4  switching C 4  to positive saturation. Since there is always current flow through the windings 18 saturable reactors may be used instead of bi-stable cores. (b) C 1  to C 4  bi-stable cores; E 1  to E 4  diodes having load line 14, i.e. only one stable state (P). C 2  in positive saturation. Shift pulse switches C 2  putting increased current through E 2  (point R of characteristic). When pulse ends Eg tends to point Q shunting current through winding 18 on C 3  and switching C 3  to positive saturation. While switching continues E 2  is held above point Q. With C 3  positively saturated Eg is restored to state P. (c) C 1  to C 4  bi-stable cores; E 1  to E 4  operating with load line 16, i.e. only one stable state (Q). This operation is similar to (b) but the state of the cores is shifted from right to left. (d) C 1  to C 4  bi-stable cores or saturable reactors; E 1  to E 4  operating with load line 12, two bi-stable states and initially in state Q. The operation is similar to (a) but shifting is from right to left. A reversible shift register is described (Fig. 3, not shown) in which two cores or saturable reactors are associated with each tunnel diode. The direction of shift depends on which set of cores is connected to a switchable pulse source.

Abstract: 1,247,054. Electric selective signalling; speech recognition. SANDERS ASSOCIATES Inc. 3 Sept., 1968, No. 41935/68. Headings G4H and G4R. [Also in Division H4] Apparatus for signal identification stores time-polarity samples of the signal then applies them to a correlation network using magnetic core elements with S-shaped hysteresis loop characteristics (term excludes square-loop). Up to 250 waveforms to be identified can be written into respective rows of a magnetic core storage matrix, each core being set or not according to the amplitude (polarity) of a respective portion of the waveform for its row. The rows can be read out in turn, parallel by bit, to the columns of a correlator matrix having 40 rows respective to different possible waveforms (i.e. different frequencies and/or phases) and magnetic cores (acting as transformers) at some row-column intersections oriented in one direction or the other. Each row wire in the correlator matrix sums the positive and negative pulses thus produced in it in response to the contents of a given row of the storage matrix, and this sum exceeds a threshold in the case of one row wire (or the correlator matrix) to identify the waveform. A second embodiment has only two rows of cores in the correlator matrix, oriented in one direction in one row and in the other direction in the other row, and each of 40 sense wires (corresponding to different possible waveforms) threads one or neither of the two cores in each column. A third embodiment has only one row row of cores in the correlator matrix, each of the sense wires threading each core in either or neither direction. Extra wires and/or cores can be provided in the correlator matrix to permit identification of time-displaced waveforms. The invention may be applied to speech recognition, measurement of frequency, e.g. of sinusoids, and in Doppler radar (the 250 input waveforms coming from respective range gates data processing, and number testing apparatus.

Abstract: 1,211,196. Rail systems. NATIONAL RESEARCH DEVELOPMENT CORP. 22 Dec., 1967 [22 Sept., 1966], No. 42284/66. Heading B7L. A transport system comprises in combination, a vehicle movable along a predetermined path, means to propel the vehicle along the path, the vehicle including a load supporting surface, means to mount at least the load supporting surface for tilting movement with respect to the horizontal about an axis transverse to the direction of the path, means to effect the tilting movement, and means to correlate the degree of tilt and horizontal component of acceleration or deceleration of the vehicle so that loads on the surface are subjected to substantially no net toppling moments by the horizontal components of acceleration or deceleration in the direction of the path. In the embodiment shown in Fig. 2, the vehicle comprises a chassis 3 provided with wheels 4 movable along rails 5 by drive cables 10 and a prime mover 11. The load supporting surface is the floor of a passenger compartment 1 pivoted, via a bracket at 2, to the chassis 3 on a transverse axis. An extension 9 of the bracket is pivotally connected at 8 to the reciprocable arm 7 of an actuator 6 mounted on the chassis and which effects the tilting of the compartment 1. A passenger entering the compartment 1 can operate a control 12 to set the prime mover 11 in operation. The actuator 6 is operated to the appropriate extent in the appropriate sense by a signal 13 from a comparator device 14, the signal 13 being the difference between a signal 15 representing the desired position of actuator 6, derived from an accelerometer 16, and a signal 17 which represents the achieved position of the actuator and/or the degree of tilt of the load supporting surface of the vehicle and is derived from a transducer 18. In another embodiment the control 12 operates the actuator 6 whereby the acceleration of the vehicle is arranged to match the degree of tilt of the load supporting surface, instead of matching the degree of tilt to the rate of acceleration as in Fig. 2. The vehicle may be slidable along the path or supported by fluid cushions and may be propelled by jet-reaction, conventional traction means or by linear electrical motors.
