Title: Shift register
IPC: G11C19/08
Filed: 1972-01-14
Abstract: 1342694 Magnetic storage arrangements TECSI TECHNIQUES ET SYSTEMES INFORMATIQUES 14 Jan 1972 [14 Jan 1971] 1951/72 Heading H3B In a shift register, Fig. 5, magnetic domains are propagated along a thin film strip of magnetic storage material which comprises an inner zone of relatively low coercivity (denoted by cross-hatching), and an outer zone of higher coercivity, the strip having a transverse easy axis of magnetisation and the boundaries between the two zones lengthwise of the strip being in the form of two groups of regular sawteeth 10, 12, 14 and 11, 13, 15 with one group off-set relatively to the other. The edges of the teeth facing the direction of propagation are normal to the strip direction, and the teeth are triangular in form preferably with their tips extended by the trapezoidal extensions shown. Propagation of domains is effected by pulsing a strip conductor A and a U-shaped conductor B with currents iA and iB, the pulse time positions and polarity being shown in Fig. 7. Writing into the register is effected by a current iC in a transverse strip conductor C overlying an extended region of lower coercivity 19. A further extended region 20 couples the propagated domains with an output conductor D or a magnetoresistive detector. A modified writing arrangement, Fig. 6 (not shown), has a conductor C<SP>1</SP> coupled with the tip only of region 19. Fig. 8 shows a further modification in which the conductor C is dispensed with and writing is effected by applying a pulse to conductor B at the same time as a positive pulse is applied to conductor A. The magnetic thin film is deposited by evaporation on a glass substrate and consists of a relatively low coercivity layer of iron, nickel and cobalt alloy comprising 5% to 25% Fe, 50% to 75% Ni and 10% to 30% Co, with a preferred composition of 15À5% Fe, 62% Ni and 22À5% Co. The relatively higher coercivity layer may be obtained by the deposition of aluminium layers or use of areas of bare glass as the low coercivity zone, or by depositing a layer of high coercivity cobalt phosphorus film over the nickel iron and cobalt alloy layer.

Title: Improvements in or relating to signal modulating devices for radio telegraph transmitters
IPC: H03F1/06
Filed: 1943-02-05
Abstract: 563,385. Valve modulating circuits. FFENNELL, H. S. MOLYNEUX-, and VACUUM-SCIENCE PRODUCTS, Ltd. Feb. 5, 1943, No. 1980. [Class 40 (v)] In a tone-modulated radio telegraphy system, the tone frequency comprises pulses of which at least the positive halves are of square form, the pulses being generated in a multi-vibrator circuit, and applied to a grid of the carrier wave generator valve, or to a grid of an output valve following that generator, so that the output valve passes current only during the positive halves of the pulses, and operates with increased efficiency. As shown, the pulses are generated in a multi-vibrator V1, and the carrier wave in a back-coupled oscillator valve V2. Both outputs are fed to the control grid 26 of the output valve V3 which grid is negatively biassed at GB - through a leak resistance 32 and radio frequency choke 25. The bias is such that only the positive halves of the pulses allow current to pass in the valve V3. Keying is effected by a switch 42 in the cathode lead of the valve V3. In a modified circuit, the pulses from V1 are applied to a grid of the generator valve V2 so as to suppress or reduce oscillation during the negative halves of the pulses, the output valve being biassed so as to be non-conducting during the negative halves.

Title: Improved devices for rotating a rotary member from a location distant from the member
IPC: F16H27/04
Filed: 1949-01-26
Abstract: 656,995. Electric selective signalling. WILLIAMS, H. M. Jan. 26, 1949, No. 2084. [Class 40 (i)] [Also in Group XXIV] Two electromagnetically operated ratchet devices (see Group XXIV), are interconnected by a system of electrical relays so that stepby-step operation of one device is transmitted to the other at a distance and vice versa. The device at the top of Fig. 7 comprises a rotatable disc 78 with operating electromagnets 77, 77a, and holding magnets 71, 71a for actuating bars 72, 72a carrying pawls 715. Relay coils 731 and 731a operate a switch arm 734 controlling the energization of magnets 77, 77a and 71, 71a through contacts 735 and 736 from a supply source 732. Switches 720 and 720a are also provided adapted to be actuated on manual operation of the disc 78 to control a pair of relays 831, 831a of the device shown at the bottom of Fig. 7. This device is a duplication of the first device and has switches 820, 820a which control the relays 731, 731a of the first device. Thus, step-by-step manual operation of one disc 78 or 88 in either direction effects through the appropriate relay on operation of the electromagnetic ratchet mechanism of the other in corresponding single steps. In Fig. 8 an arrangement is shown in which the operation in corresponding single steps only is not necessary and two shafts 99 and 109 are maintained in the same angular relation by means of a bridge circuit comprising resistors 943 and 1043, sliding contact arms 942 and 1042 coupled to the shafts 99 and 109 and relays 941 and 1041. In a condition of balance of the bridge equal currents flow through all of the relays but if one shaft is rotated through an angle the bridge is unbalanced and either of the actuating electromagnets 97, 97a and 107, 107a of both devices will operate in reverse directions to bring the shafts back to the same angular relation and to adjust the resistors 943, 1043 to restore the condition of balance. The electromagnets will continue to operate in a succession of steps by virtue of make-andbreak switches 939, 939a and 1039, 1039a in the circuits of the electromagnets controlled by the armature movements until the balance is restored. One or the other of the shafts may be held manually against the operating forces in which case the other shaft only will be actuated until it resumes the previous angular relation. Alternatively one of the relays, for example, 941 could be omitted and the shaft 109 would then follow the movements of shaft 99 but not vice versa.

Abstract: 310,438. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 23, 1928. Mineral and tar oils.-Oils comprising oxygenated organic compounds are obtained by treating aliphatic or hydroaromatic hydrocarbons or their derivatives with carbon monoxide under pressure in the presence of anhydrous halides of aluminium and/or boron. The reaction may be applied to individual hydrocarbons or to hydrocarbon mixtures such as petroleum ether, ligroin, benzine, lamp oil, purified petroleum jelly, paraffin wax, brown coal tar oils, cracking products, and the destructive hydrogenation products of coal, tar, and mineral oils. The preferred reaction conditions are a pressure of 80-150 atmospheres and a temperature of 30-60‹ C. Two of the examples describe the treatment of a heavy benzine boiling at 150- 200‹ C., whereby oily oxygenated producted are obtained, and of a petroleum fraction boiling at 150-300‹ C. and free from olefines. In the latter case an oil product is obtained, the constituents of the product which are not volatile in steam being suitable for lubricating.
