Patent GB-1312706-A (GB)
Title: Keyboard operated transmitter
IPC: H04L17/04
Filed: 1970-07-07
Abstract: 1312706 Teleprinters MITE CORP 7 July 1970 [4 Sept 1969] 32971/71 Heading H4P A coding arrangement, particularly for a teleprinter keyboard, comprises a printed circuit board having a plurality of conductive areas with contact means, coupled to code bars, selectively engaging with the areas. Depression of any character key moves a code bar (28 &c.) laterally by means of a plug sliding into an angled notch 74 in the bars so that spring-loaded contacts 98 on arm 90 engage with appropriate ones of raised contacts 91, 93 &c. giving a coded signal, dependent upon the position of a bar, which may be transmitted. Certain switches (e.g. S3, Fig. 7, not shown) are operated by shift keys to reverse the signal combination, i.e. 0's for 1's and vice versa.  A parity bit may be added by an additional code bar to provide for example an even number of bits or an even number of 1's. An interlock is provided (60, Fig. 6, not shown) which is only closed when a key is fully depressed so that signals are not issued if a code bar is only partly shifted. A repeat key (166, Fig. 7, not shown) may be included on the keyboard. A mechanism (156, Fig. 1, not shown) is provided to multiply the motion of the spacer bar (12). Seven notched code bars, as disclosed in Canadian Specification 689,580, are provided normally to develop a seven unit code together with three shift keys. The latter described provides single current signals but may be adapted to provide polar switching. Codes having other than seven units may be employed.

Title: Magnetic thin film storage device
IPC: H01F10/06
Filed: 1975-08-07
Abstract: 1507566 Magnetic storage arrangements BASF AG 7 Aug 1975 [8 Aug 1974] 32988/75 Heading H3B Magnetic domains 27, Fig. 1a, representing the same binary digit are transmitted in parallel along a group of propagation channels 24 formed by adjacent stripe regions in a flat magnetic layer 20 of higher coercivity, each channel being terminated by enlarged read and write areas 26, 25 respectively associated with a read and a write conductor 42, 41 common to the group. With this arrangement a defective propagation channel does not significantly affect the signal read out. The magnetic layer may be a 64:15:21 Ni/Fe/Co alloy having an in-plane easy magnetization axis 21, the layer being deposited to a thickness of between 10 and 500 nm on a glass substrate 10. The lower coercivity stripe regions forming the propagation channels are defined by raising the coercivity of the remainder of the layer by diffusion, roughening or exchange coupling with a high coercivity overlay. Roughening to increase the coercivity is preferred, and is effected before formation of the magnetic layer by selectively depositing an ultra thin aluminium layer 22, Fig. 1b, on the substrate. In the arrangement shown binary digits represented by pulses in group write conductors 41 are selectively entered as domains in parallel groups each of four propagation channels, the domains being advanced in line from the write to the read areas by selectively pulsing drive conductors 81, 62, 83, 64, 62... separated into two planes by insulating layers 50, 70. In a modification, Fig. 3a, the groups of channels are of progressively increased length with domains created simultaneously in each group at the commencement of each propagation cycle. The binary digits to be transmitted are entered serially in the form of "no pulse" or "pulse" signals applied to a stepped common conductor 41, a pulse preventing transmission of the generated domains in a propagation group if the digit to be entered in that group is zero. A stepped common conductor 42 reads out the transmitted digits in serial form. A similar embodiment but with the groups of channels of equal length is also described, Fig. 5a (not shown), a total of eight digits being entered sequentially in eight groups of propagation channels, and the representative domains being advanced to a common starting position before the drive conductors are energized.

Filed: 1976-08-10
Abstract: 1524595 Converting L RUGGERI 10 Aug 1976 [13 Aug 1975] 33239/76 Heading H2F An electrical A.C. to D.C. conversion device comprises a conductor 21 having an elongated cross-sectional shape and disposed in a slot in a ferromagnetic laminated core 27, the walls of this slot being arranged to be just magnetically saturated by an external magnetic control field due to a control coil 20 so that when a positive half cycle of current flows through the conductor 21 the additional flux 31 due to this current aids the control field 30 and drives the walls further into saturation so that no eddy currents flow and the conductor 21 conducts a maximum of current, but when a negative half cycle of current flows through the conductor 21 the flux due to this current opposes the control field, the walls of the slot are unsaturated and eddy currents flow therein inducing back e.m.f., and thus current opposing the current in conductor 21 so that the current in that conductor is reduced to a minimum. The conductor 21 preferable has a T-shaped cross-section. Fig. lb not shown. In addition by changing the value of the no-load magnetic bias flux due to the control field regulation of current in conductor 21 is also achieved. Full wave forms of the conversion device having two conductors 21, 22 are also described, Figs. 6, not shown and Fig. 7, and in these embodiments the control field may be constant when one conductor conducts a maximum while the other conducts a minimum of current, or varying when both conductors are made to conduct a maximum or a minimum of current simultaneously. An embodiment of the device having a plurality of conductors with cyclic variation of the control field is described, Fig. 10, not shown, this device having a stator, carrying the control windings wound on poles, within which is a rotor carrying the conductors in slots.

Abstract: 1,213,028. Electromechanical delay lines; radar. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. 11 July, 1968 [11 July, 1967], No. 33240/68. Headings H3U and H4D. A delay line intended to function as a radar echo simulator by producing a signal identical to that received from a moving target illuminated by a radar using the Doppler effect, comprises a piezo-electric transducer 1 having electrodes 2, 3 and mechanically coupled through a dielectric element 7 to a rod 4 of piezo-electric material. Electrodes 5, 6 at the rod ends enable a modulating signal S 2  to be applied to the rod. The input signal S 1  is applied to the electrodes 2, 3 through an input-output separator 8, an acoustic wave being propagated along the length of the rod 4, reflected from the remote end, and received back as a delayed output signal S 3 . The Doppler frequency shift is introduced by the modulating signal S 2  which applies a sawtooth waveform during the whole period of the input signal S 1 . The change in the rod length due to the signal S 2  causes the frequency to be shifted by an amount dependent on the slope of the sawtooth waveform.
