Title: Angular modulation transmission systems
Inventor: RAVENSCROFT IVOR ALBERT
IPC: H04B14/00
Filed: 1961-02-03
Abstract: 985,807. Frequency or phase modulation; automatic frequency control systems. POSTMASTER-GENERAL. Feb. 2, 1962 [Feb. 3, 1961], No. 4245/61. Headings H3A and H3R. In an angle modulation system the carrier frequency component is reduced by a filter at the transmitter after the modulation stage and restored by a complementary equalizer network at the receiver, to increase the effective modulation index, apart from any pre-emphasis or deemphasis of the frequency or phase modulation signal respectively. An exploring oscillation of frequency e.g. 100 kc./s., below the modulation baseband, may be added to the latter before the modulation stage so that if any mean frequency drift of the modulated oscillator occurs the exploring frequency detected as rectifier output of the carrier filter acting as a frequency discriminator is phase shifted due to the carrier filter and after detection of this phase shift relative to the exploring frequency in a phase discriminator an A.F.C. mean frequency correcting voltage may be applied to the oscillator. At a receiver an exploring frequency (e.g. around 100 kc./s.) frequency modulates by a small amount a local oscillator and any frequency drift of the I.F. produces from an amplitude detector at the output of the complementary filter a phase shift of the exploring frequency which detected in a phase discriminator, relative to the original exploring frequency, produces an A.F.C. voltage for the local oscillator. Alternatively, at a receiver the transmitter exploring frequency may be detected in a frequency discriminator energized from the input to the receiver filter and also detected from an amplitude detector at the filter output, and phase variation is detected in a phase discriminator as an A.F.C. voltage for the receiver local oscillator.

Title: Improvements in or relating to production of ammonia and oxides of sulfur from ammonium sulfate
IPC: C01B17/50
Filed: 1954-02-15
Abstract: Ammonium sulphate or acid sulphate is decomposed into amonia and oxides of sulphur by mixing the sulphate with nickel, strontium, or zinc oxide, heating the mixture to between 300 and 500 DEG C. until substantially all the ammonia has been recovered, subjecting the residue solids to heating between 850 and 1200 DEG C. and recovering gaseous oxides of sulphur.  The resultant metal oxide solids may be recycled to the mixing step, and the heating steps may be carried out batchwise or continuously.  In the example ammonium sulphate is ground with a stoichiometric excess of zinc oxide and the uniform mixture is calcined at 440 DEG C. with recovery of ammonia.  The zinc sulphate is then heated at 1000 DEG C. with recovery of a mixture of sulphur dioxide and trioxide.  The zinc oxide may be diluted with zinc sulphate or inert solid such as alumina or aluminium silicate. Specification 124,842 [Class 1(ii)] is referred to.

Abstract: 102,660. Perry, F., and Metalloids, Ltd. March 25, 1916. Annealing.-In annealing metal articles in an atmosphere of Mond or other producer gas, the saturated hydrocarbons such as methane, in addition to other constituents such as water vapour, sulphur compounds and insaturated hydrocarbons, are removed from the gas prior to its passage into contact with the metal articles.

Title: Improvements in and relating to data retrieval apparatus
IPC: B42F17/34
Filed: 1960-02-09
Abstract: 918,582. Digital data storage apparatus; statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 9, 1960 [Feb. 9, 1959 ; Feb. 16, 1959], No. 4492/60. Class 106 (1). A flexible record carrier, e.g. a magnetic tape or wire strip or a punched card is selected from a store of such carriers and positioned on a support member which then moves the selected carrier in a closed path past a data reading or writing unit to a position from which the carrier is returned to the store. As shown, magnetic tape strips 20 are identified by tabs 21, one to a strip, and a strip 20s is selected by separating adjacent strips from strip 20s as by members 23a, 23b (Fig. 1a) fingers 74 (Fig. 1) or jets of air directed at the tabs. A tooth 59 on latch member 57 mounted in a picker body 56 is then brought into engagement with a slot either in the tab 21 or the body of the selected carrier 20s. There may be more than one latch and slot. The body 56 is supported on a drum 42 or a pulley and belt arrangement which is then rotated to latch the carrier 20s in a cut-out portion of the drum surface and to move the carrier past a transducer 44 and guiding rollers 90. Anticlockwise rotation continues for the number of revolutions necessary to complete the reading or writing operation after which the drum is stopped the carrier unlatched from the drum and returned to store by clockwise drum rotation. The latch 57 and fingers 74 are then released. The fingers 74 are slidable on rods 71 and are moved to position of use by any suitable means acting on yoke 75. The rotation of the fingers may be derived from the motion of the drum carrying the descending picker body 56. The fingers, spaced apart about one tab's width, are initially in a horizontal position and are rotated outwardly to engage the tabs. Specification 918,581 is referred to.

Title: Improvements in and relating to the manufacture of porous artificial stone
IPC: C04B28/22
Filed: 1935-02-12
Abstract: Building-blocks and the like are made by moulding a wet mixture of siliceous and/or argillaceous material, quick-lime, and a compound of an oxy-acid of sulphur, allowing the lime to hydrate, and hardening by steam under pressure.  Calcium sulphate may be employed as the sul hur-containing compound, or a material rich in sulphur, such as colliery shale may be used.  The composition should not be so rich in quick-lime that the temperature of hydration rises to the boiling point of the solution, to avoid undue expansion.  However, setting is accelerated by raising the temperature, 35-40 DEG  C. being suitable. According to an example, 7 parts of sand are mixed with 1 part of quick-lime; 3 per cent of ground gypsum is added.  This is mixed with 15-40 per cent of water and the mass is moulded and allowed to hydrate and set (2-4 hours or longer).  The blocks are removed from the moulds and hardened in steam at 120 lbs. for 8 hours.  Porous blocks may be obtained by adding aluminium powder or the like to the mix, the porosity being controlled by the amount of powder added, and by the temperature of the water.

Immunizing and like serums; medicines for internal use.-Medicinal substances for the prevention or treatment of bacterial and like diseases are obtained from the glands or other organs, or the blood, of a healthy animal which has been treated, by injection or otherwise, with chemical compounds of the pyridine, quinoline, or isoquinolene series capable of acting upon the causative agents in question, such as spirilla, trypanosomes, or cocci. In conjunction with the treatment with chemicals, the animal may be inoculated with an attenuated or virulent culture of the bacteria of a particular disease, so as to produce specific immunizing serum at the same time as the general or group immunizing substances are produced by the chemical treatment. The chemical compounds used are pyridine, quinoline, and isoquinoline substituted, preferably in the ortho position relative to the hetero atom, with biologically active elements or groups such as arsenic, antimony, halogens, hydroxyl, carboxyl, or phenyl, for instance those described in Specification 250,287, [Class 2 (iii), Dyes &c.], such as the disodium salt of 2 oxy-pyridine-5-arsinic acid. Other examples are 2-oxy-5-iodopyridine, 2-chloro- 5-iodopyridine, and other iodized pyridine derivatives described in Specification 251,578, [Class 2 (iii), Dyes &c.]. Reference is made to known methods of obtaining serums, toxins &c. by treatment of animals with organic substances in conjunction with bacteria, with lipoids such as lecithin, or with lipoids in conjunction with spirochµtae and gall, or by treatment of tuberculous animals with sodium cinnamate. The Specification, as open to inspection under Sect. 91 (3) (a) is not limited to the use of particular classes of compounds, but refers also to the use of compounds of the pyrrol series, of com. pounds containing selenium or cyanogen as substituents, and to the simultaneous use of more than one chemical compound.

In these cases, the converter may include switching means responsive to the code, and a clipper for removing such modulation before applying the pilot to the means 28, Fig. 4 (not shown). In order to avoid interference with the output i.f., the pilot is transmitted at a subharmonic of the i.f. and is fed to the means 28 via a selector 32 and frequency multiplier 34.
