Abstract: 823,748. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 13, 1957 [May 14, 1956], No. 15129/57. Class 106 (1). In a digital data storage device storing data magnetically on a number of concentric tracks on both sides of each of a plurality of coaxially mounted discs, the transducing heads, one for each side of each disc, are ganged for simultaneous movement. The heads (not shown, but being of the air-bearing type described in Specifications 764,434, [Group XXXVIII], and 804,648, [Group XVI] both of which are referred to), are mounted on the ends of arms 21, Figs. 1, 2, which are fixed to a vertical pillar 22. The heads are positioned in accordance with an externally applied digitally coded track selecting signal, which by means of appropriate solenoids and half-rotation clutches causes one or more of the digitally weighted eccentrically mounted pulleys 32 to make half a revolution thereby approximately positioning the heads in the desired position. Once this course positioning is complete a further solenoid is energized to cause the homing of the heads on to the nearest track. This is achieved by a null-seeking servo system comprising a special set of timing tracks on one of the discs, each track having recorded along it two sine waves 180 degrees out of phase with each other and being read by a wide head having two reading coils on it, a motor 89, Fig. 2, which rotates the pillar 22 through the gears shown, and an appropriate balanced amplifier (Fig. 7, not shown).

Title: Improvements in carrier-wave telegraphy
IPC: H04B1/66
Filed: 1954-05-27
Abstract: 746,726. Multiplex systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 27, 1954 [May 30, 1953], No. 15735/54. Class 40(4). In a carrier telegraph system the channels which occupy a speech frequency band, i.e. 420- 3180 c/s., on the transmission medium are divided into four groups, the centre two (1140-1740, 1860-2460) of which comprise in each channel an oscillator supplying the transmitted channel frequency, and the two outside groups (420-1020, 2580-3180 c/s.) comprise channel oscillators having frequencies which are identical with the more remote of the centre two groups (1860-2460, 1140-1740) respectively, a second modulator being provided to transpose each group to its position in the transmitted spectrum. With this arrangement the bulky filters normally necessary for very low frequencies of the order of 400-600 cycles and the complicated filters necessary to obtain a desirable selectivity at frequencies above 3000 cycles, are avoided. The 24-channel system, Fig. 1, occupies a frequency band of 420-3180 cycles on the cable 23, and carrier frequencies 1140-1740 and 1860-2460 cycles are generated for direct application to the line in oscillators 12, 13. The sending keys 16, 17 cause, for example, frequency shift signals to be transmitted. The oscillators 11 in group 3 generate frequencies corresponding to group 5, i.e. 1860-2460 cycles and the group output is modulated by a frequency of 2880 cycles to transpose the group to the lower end of the band, i.e. 420-1020. The group 6 in which the channel oscillator frequencies correspond to those of group 4 is similarly shifted to a band 2580-3180 cycles to fully utilize the speech band available in the transmission medium. At the receiving end 2 the 420-1020 cycles band is transposed to 1860-2460 cycles in group modulator 58, the 2580-3180 cycles band is transposed to the 1140-1740 cycles band in modulator 61 and the centre bands are directly received. The application of the invention to a two-way system is described with reference to Fig. 2 (not shown), and in this application the highest frequency channel of the lower centre group 1620-1740 cycles and the lowest frequency channel of the higher centre group 1860-1980 cycles are omitted to facilitate directional filtering. Further applications to a diversity reception radio telegraph system using channels spaced by 600 cycles and to a system in which branch stations are taken off from a main route are described with reference to Figs. 3 and 4 (not shown), respectively.

Abstract: 134,264. Acetylene Equipment Co., and Stephenson, A. Sept. 30, 1918. Blowpipe burners.-In a welding blowpipe burner, additional oxygen is supplied at the base of the flame envelope symmetrically round the flame so as to make the burner more independent of the atmospheric air, increase the rate of combustion, and reduce the size of the flame. The additional oxygen is supplied through a pipe B<2>, to a cavity B<1> communicating with an annular passage b merging into a smaller annulus b<1> which directs the oxygen on to the envelope of the flame. In a modification, the annular passage b is replaced by a series of holes arranged round the central passage. In the form shown in Fig. 10, the additional oxygen from the pipe B<2> passes partly to an annular passage B<3> surrounding the main annular passage A<1>, and partly to the central tube b<x> and through holes B<4> surrounded by the passage A<1>, thus impinging on both the outer and inner portions of the annular flame. In the form shown in Fig. 12, the additional oxygen is supplied to the combustible mixture before it leaves the tip, by being supplied from the pipe B<2> to holes b<2> which communicate with the outlet at a small distance behind the face of the tip. The amounts of oxygen supplied to the main jet and the additional supply are automatically controlled by a device comprising a casing C divided into two compartments C<1>, C<2> by a flexible diaphragm C<3> operating, by means of spring-pressed rods C<3x>, bell-crank levers C<4>. These levers actuate valves C<5> in each compartment and control the apertures through which the oxygen is admitted to each of the compartments which communicate, by outlets C<7>, with the respective oxygen supplies. In a modification, the rods C<3x> are replaced by spiral springs, the inner ends of the bell-crank levers C<4> being held between two springs in tension.
