Title: Improvements in or relating to information storage devices
Inventor: CHAIMOWICZ ADAM
IPC: G11C21/02
Filed: 1957-05-31
Abstract: 873,367. Pulse storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. April 22, 1958 [May 31, 1957], No. 17350/57. Class 40 (9). [Also in Group XIX] The storage device shown in Fig. 2 comprises a magnetostrictive wire 1 supported between damping blocks 2. The wire material is such that its hysteresis characteristic changes under mechanical stress from X-Y, Fig. 1, to a more rectangular form E-F. A pulse is initially applied to winding 3 of such amplitude as to saturate the wire to point X so that it is in a uniform remanent magnetic state corresponding to point A. An 8-bit word is written by applying a serial train of " 1 "-representing pulses to winding 3 while a stress wave is propagated along the wire, each pulse being of amplitude corresponding to point P whereby the remanent state of the wire is left substantially unchanged (point A(1)) in the unstressed portion but is reversed (point C) in the stressed portion. The stress wave is launched by applying a pulse to coil 5, or alternatively by a piezo-electric crystal, and passes successively through points P(1)-P(8) which are thus selectively magnetized to represent the word. The word may be read out by applying a further pulse to coil 5, the passage of the resultant stress wave along the wire causing a pulse to be induced in winding 3 for each point at which a " 1 " is stored. In a multiple storage device (Fig. 3, not shown), a stress-wave producing coil similar to 5 is common to a set of storage wires contained in parallel channels of a supporting block. The information stored in the different wires may be interleaved. The wires may be replaced by ribbons or tubes, and each coil such as 3 may be replaced by individual coils, one for each digit storage position. In a further modification, a word is written on to the storage wire 1 by applying a pulse train to coil 5, and a single pulse to winding 3. The wire may be pre-stressed so as to obtain the rectangular hysteresis characteristic, the stress waves obtained through coil 5, representing the complement of the information to be stored, changing the characteristic back to the original form. Alternatively, pre-stressing may be employed effectively to increase the difference between the two hysteresis characteristics. Specification 698,061 is referred to. Reference has been directed by the Comptroller to Specification 780,005.

Inductances.-In tuning and other wireless apparatus with two relatively rotatable members carrying coils &c,. one member being adjusted bv means of a longitudinally moving, screwthreaded, operating rod, the rod is formed' in two parts, each having a manipulating handle or knob, one part 11 surrounding the other part 13 and having screw-threaded engagement with a fixed nut 8 in the fixed member 4 whilst the part 13 extends at both ends from, and is in screwthreaded engagement with, the part 11 and is connected at its end to the moving member 18. The screw-threads between the parts 8, 11 are coarse and preferably of double or triple thread and the threads between the parts 11, 13 are fine and of single thread. Fine adjustment of the member 18 is made by turning the knob 14 on the part 13, the part 11 remaining stationary, and coarse adjustment by turning the knob 12 on the part 11, the parts 11, 13 moving together. The parts 11, 13 may be locked together by means of a nut on the screw-threads of the part 13 screwing against the end of the part 11 or the knob 12 so that the parts 11, 13 may be turned together for coarse adjustment by the knob 14.

Abstract: 1355354 Doppler radar TOYOTA JIDOSHA KOGYO KK 27 May 1971 [23 July 1970] 17693/71 Heading H4D  A velocity measuring system comprises an oscillator, a random noise source, means for  frequency modulating the oscillator output in response to the noise signal means for radiating the modulated signal and receiving reflected waves, means for mixing the radiated and received waves and means for low-pass filtering the difference frequency detecting the filtered frequency which is proportional to the velocity of a target. A Doppler radar mounted on an automobile for collision avoidance incorporates a Gunn effect oscillator 4 which is frequency modulated by a noise signal, band limited by filter 2. The echo signals are mixed with a portion of the transmitter signals and the resulting Doppler signals are low pass filtered and displayed on a frequency counter or integrating meter. By using a random frequency modulation the possibility of receiving interference from other vehicles is reduced. By a suitable choice of the maximum frequency deviation and the modulation index, a second peak in the frequency spectrum of the received signals is produced which is a function of the target range, due to the change in transmission frequency during the signal transit time. The two peaks can be separated by suitable filtering.
