Patent GB-146893-A (GB)
Abstract: 146,893. Optische Anstalt C. P. Goerz Akt.-Ges. Oct. 15, 1918, [Convention date]. Printing totals and sub-totals.-Relates to means for controlling the engagement, in key-set independently-operated calculating machines, of the totalizing-counter wheels and the type-setting elements so as to print a sub-total or a total on operation of the corresponding key. The counter is supported by a part having a pin bearing against a cam 2, Fig. 1, which is rocked at the proper time for adding the item set by the keys, or for transmitting a total from the counter to the type elements and restoring it, or not through a pair of links 8, 9 pivoted to a pair of rocking-plates 11, 12 engaged by a pair of cams 14, 15 on the main crank spindle. The links 8, 9 have L- shaped slots to engage a pin 5 on the cam-plate 2 and rock it, and are set by levers 21, 21<1> and links 22, 22<1> controlled by the sub-total and total keys respectively. In Fig. 1 the links are shown set for printing items set by the keys, which are added when the supporting-pin is lowered. The sub-total key rocks a plate 23, thereby sliding the link 22 to rock the lever 21 forward and dip the link 8, at the same time a link 27 is ungeared from a pin 26 on lever 11 and thus disables the key-set stops, enabling the segments to travel till the counter wheels meet their zero stops, and to pick up the total therefrom. For a grand total the link 22<1> is moved by its key, carrying along with it the link 22, though the engagement of extensions 50, 51, whereupon the key stops to the segments are disabled as for the sub-total, but the second link 9 is positioned to move cam-plate 2 and lift the counter out of gear while at zero. The levers 21, 21<1> engage spring-controlled one-way pawls 29 on the links 8, 9 to permit correct movement of the links. Special stops are set for thus zeroizing the counter wheels by the sub-total and total keys through a lever 36, Fig. 7, fast with the rocking-plate 23, which rocks, by a link 37, an arm 40 into position to engage a slide 43, when the counter frame descends. The slide thus raises a set of arms 34 pivoted at 33 to bring stops 32 into the path of ears 31, one to each counter wheel. The position of the parts 40 in or out of action is maintained by a lever 45 geared to the link 37, and having a roller 46 to lie inside or outside a locking flange 47 on a plate 48 on the main spindle.

Filed: 1972-12-01
Abstract: 1414978 Electrets SONY CORP 1 Dec 1972 [2 Dec 1971] 14703/75 Divided out of 1414977 Heading H1M An electret comprises an electrically conductive substrate having on one surface thereof superposed, contiguous first and second layers of different inorganic insulating materials, said layers of inorganic insulating material carrying a permanent charge. After being deposited, the inorganic material is charged, preferably by subjecting it to electron beam radiation or other charged particle radiation, or by diffusion of sodium or potassium into it, or by applying a direct voltage between the substrate and the exposed surface of the insulating layer. Preferably the electret structure is made using aluminium sheet 24, thickness 2 mm. (Fig. 6c) on which is vapour deposited gold of thickness 0À1 Á. On top of this layer is deposited an inorganic insulator 27 in two layers, e.g. of silicon dioxide, aluminium oxide, titanium dioxide, silicon nitride, or an adduct of phosphorus pentoxide and silicon dioxide, layer 27 is then exposed to an electron beam to permanently charge it. For example, a layer of aluminium oxide of thickness 1500 Š to 2000 Š and a layer of silicon dioxide of thickness 100 Š to 300 Š are successively vapour deposited, whereupon the two layers are charged. Another combination of two layers consists of silicon nitride and silicon dioxide. After the layer 27 has been charged, a further layer 28 of metal (e.g. aluminium of thickness about 10 Á) is vapour deposited. Subsequently holes 29, 31 (Figs. 6D) are etched chemically through the metal layers 24, 28 to leave a deformable central area consisting of electret material 27 and gold 26. Thereafter, individual electret structures are cut out of a large sheet by cutting along lines 32 to form circular structures of diameter to suit an electret transducer such as a microphone. Remainder portions 24, 28 support the diaphragm layers 26, 27. Microphones utilizing the electrets are claimed in Specification 1,414,977.

Patent GB-815193-A (GB)
Title: Process for removing sulphur compounds from a mixture of hydrocarbons
IPC: C07C7/171
Filed: 1957-05-09
Abstract: Sulphur compounds are removed from a mixture of hydrocarbons containing mono- and/or di-olefins, by stirring the mixture in a mixer with an acid phase containing sulphuric acid, separating the hydrocarbon phase from the acid phase and distilling the hydrocarbon phase.  The acid phase consists of 15-60 per cent by weight of organic oxygen, nitrogen and sulphur compounds such as can be extracted from mineral oil by sulphuric acid, and of water and sulphuric acid, the concentration of acid being 60-93 per cent based on the weight of acid and water.  The stirring is effected in such a way that the mechanical power transferred by the stirring elements to the mixture of both phases is at least 0.1 kw/m3 of mixture.  The ratio of acid phase to hydrocarbon phase in the mixture is at least 10/100 in parts by volume.  After separation of the phases, the hydrocarbon phase is freed from acid, e.g. by washing with caustic alkali and water; caustic alkali or ammonia may also be injected into the hydrocarbons during distillation and the distillate may be washed with caustic alkali solution.  The treatment may be carried out batchwise, or preferably continuously, wherein the acid phase is recycled and fresh acid is introduced into the recycle line. Propeller mixers and centrifugal mixers of the turbo-mixer type may be used.  The acid phase may be prepared by continuously mixing mineral oil, e.g. cracked gasoline, with sulphuric acid (of at least 90 per cent concentration), or oleum, separating the hydrocarbon phase, and recycling the acid phase containing oxygen, nitrogen and sulphur compounds extracted from the oil.  The fresh acid added to the recycled acid may be sulphuric acid or oleum or a recycled acid phase waste acid from other sulphuric acid treatments, with or without fresh sulphuric acid or oleum. Isoparaffins having not more than 6 carbon atoms, e.g. isobutane, may be added to the oil before treatment.  The treatment may be carried out at 0-100 DEG  C.  The hydrocarbons may be separated into a fraction boiling up to 200 DEG C. which is acid treated and a fraction boiling above 200 DEG  C. which is catalytically hydrogenated, and the two fractions then combined.  The process may also be carried out in two stages. Hydrocarbons which may be treated are thermally or catalytically cracked hydrocarbon oils, e.g. cracked gasoline, thermally reformed naphthas, heavy straight run gasolines and light tar oil distillates, e.g. benzene-containing distillates, and shale oil distillates.  In the examples, the treatment of cracked gasolines of B.P. 130-200 DEG C. and 100-220 DEG  C. and of raw benzene (which may be first treated with sodium bisulphate to remove nitrogen bases) is described; and in another example cracked gasoline of B.P. 40-205 DEG  C. is distilled; the fraction of B.P. 40-100 DEG  C. washed with caustic alkali and treated with phenolic caustic alkali solution in the presence of oxygen; and the fraction boiling above 100 DEG  C. is treated according to the invention.

Abstract: 291,012. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Peterson, H. 0.). May 23, 1927, [Convention date]. Thermionic heterodyne receivers.-In order to prevent re-radiation from the local oscillator in a heterodyne or superheterodyne set, the signal energy and the local oscillations are applied across conjugate points on a Wheatstone-bridge arrangement, to which the combining circuit or detector valve is connected asymmetrically. As shown in Fig. 1, the aerial inductance 6 is coupled to a split inductance 24, 26 tuned by a condenser 28 to the signal frequency, so that induced currents flow through the coils 24, 26. in series. The local oscillator 12 is enclosed within a double copper shield 10, and feeds energy through a coupling circuit 32 to the midpoint of the input so that current flows through the coils 24, 26 in parallel and is not therefore transferred to the aerial. The condenser 30, which is made equal to the overall grid-tocathode capacitance of the valve 16 including the shielding and earth, serves to introduce sufficient reactance to upset the balanced input from the oscillator 12 upon the valve 16, so that a rectified beat effect due to the incoming signals and local oscillations appears in the output 37. The valve 16 is biased to the rectification point by means of a battery 36. When the resultant beats are of supersonic frequency they are passed through an intermediate frequency amplifier 40 for final detection. Fig. 2 shows the equivalent balanced-bridge arrangement, the aerial signals being in effect applied across the points A, B and the local oscillations across the conjugate corners, whilst the valve input is represented by the grid 20 and filament 18. The combining valve mav be replaced by any equivalent asymmetric device, such as a saturable iron-cored inductance.
