Abstract: 350,655. Aligning bearings. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Brueshaber, M. W. ; 1122, Jackson Avenue, River Forest, Illinois, U.S.A.) April 16, 1930, No. 12107. Convention date, Sept. 28, 1929. [Class 12 (i).] The antifriction bearings of printing and impression cylinders are so constructed that they are held rotatably in position without tolerance or play relatively to the other member of a printing-couple, so that the positions of the cylinders are not affected when the impression surface and forme pass into and out of operative engagement at the margins of the pages. As applied to a rotary printing-couple in which gravity assists the printing pressure between a forme cylinder 11 and an impression cylinder 12, the shafts 13, 14 of these cylinders are mounted in split bearings comprising two sets of rollers 18, 15, between which are mounted bearer rings 19, 16 on which act other antifriction bearer members in the form of rings or rollers 30 mounted on roller bearings 31. The shaft 13 is mounted in eccentrics 17 held in place by a cap 20, and by means of a worm 22 the eccentric can be rotated to adjust the printing pressure. One of the antifriction rollers 30 is mounted in lugs 24 on the eccentric member 17, so that adjustment of the printing pressure does not affect the relative position of the roller 30 to the shaft 13. The rollers 30 are adjustable to and from the shafts 13, 14 by means of a shaft 25 with an eccentric part 28 for moving the rollers to and from the centres of the shafts 13, 14. The shafts 25 are fitted with square sockets to receive an operating-tool, and are held in adjusted position by set screws 26 accessible through slots 32, 33 in the spaced frames 10, in which the cylinders are mounted. The bearers 16 on the shafts 13, 14 may be replaced by bearer members on the ends of the cylinders.

Title: Improvements in and relating to electric power control systems employing electric power converting apparatus, particularly of the vapour electric type
IPC: H02M3/31
Filed: 1932-12-17
Abstract: 416,906. Converting ; systems depending on static transformers. FITZGERALD, A. S., 433, Warwick Road, Wynnewood, Pennsylvania, U.S.A. Dec. 17, 1932, No. 12189/34. Divided out of 413,671 under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 19, 1933. [Classes 38 (ii) and 38 (iv).] In an inverter of the type comprising a pair of uni-laterally conducting devices, e.g. vapour discharge tubes 5, 6, controlled, e.g. by grid control, so as to pass current alternately to charge and discharge a serially connected condenser 8 the charging period of which corresponds to a frequency of oscillation f the frequency of alternations in current flow through the rectifying devices being f2, the ratio f1.f2 is varied, by varying either f 1 or f2, to produce variation in the output power of the converter. The frequency f2 determines the output frequency of the converter and is arranged to be less than the frequency f1 corresponding to the charging period of the condenser 8. f2 may be varied by a control 33 on an oscillator 32 supplying grid excitation voltage to the inverter 3 and the charging period frequency f1 may be varied by varying the capacity 8 or a capacity 11 or reactance 7 or by other means controlling the charging period, the two controls functioning to vary the duration of each zero-current period and thus control the power output of the converter. The inverter may be supplied from an A.C. source 1 thus acting as a frequency changer and its output may be rectified at 12, 12 so as to obtain power at the original frequency or to provide D.C. for supply to a load 2. Two such frequency changing sets, such as 3 and 30 may be used to give an output frequency modulated by the input frequency wave-form and the corresponding rectifier arrangements 4, 40 may be arranged to provide D.C. or A.C. of the original frequency. The complete system allows of power control and filtering in an intermediateH.F.stage with corresponding reduction in size of the equipment. The arrangement is not limited to the use of vapour-discharge devices. Specification 347,474 and an article by O. Kiltie, on p. 802 of Electrical Engineering, Nov. 1932, are referred to. Reference has been directed by the Comptroller to British Specifications 15031/10, [Class 38 (ii)], 393,563, 395,425, and U.S.A. Specification 1,802,677.
Patent GB-611213-A (GB)
Title: Method for purifying naphthalene
IPC: C07C7/14
Filed: 1945-05-15
Abstract: Naphthalene is purified by centrifugally extracting the major part of the hydrocarbon oils occluded in the naphthalene crystals, washing the mass, preferably in the same centrifugal apparatus, with an auxiliary liquid or liquid mixture having a boiling point of not more than 190 DEG  C. and the surface tension of which is lower than that of the occluded hydrocarbon oil to be removed, purifying the raw washed naphthalene by treatment with soda and sulphuric acid, and separating commercially pure naphthalene from the auxiliary liquid or liquid mixture by fractional distillation. The substitution may also be effected by filtering under vacuum, suction, or successive diffusions and a suitable liquid is an oil fraction from coal distillation boiling between 160 DEG  and 190 DEG  C. Solvents for naphthalene are generally used, but alcohols may also be used.  When solvents are used, it is preferable to saturate initially with pure naphthalene in the cold.  After use the washing liquid is regenerated by distillation to extract therefrom the dissolved hydrocarbons and is then recycled.  In an example, crude naphthalene oil resulting from the distillation of coal tar is centrifuged and the product then washed in the centrifuge with commercial xylene having a boiling point of 140 DEG  C.  The washed naphthalene is then treated with soda and sulphuric acid and then fractionally distilled to remove the xylene.

Title: Improvements in or relating to escapement devices, particularly for printing telegraph apparatus
IPC: H04L19/00
Filed: 1940-07-26
Abstract: 542,778. Type-printing telegraphy. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. July 26, 1940, No. 12205. [Class 40 (iii)] Escapements, particularly in step-by-step printing telegraph receivers, are controlled by a mechanical relay device operated by the armature of an electromagnet. The power for operating the mechanical relay is derived from the power shaft driving the escapement. The type-wheel spindle 2, driven by a spring, is geared to the escapement spindle 5 having stop arms 6, 7 engaged by arms 10, 13 of three-armed levers 8, 9, the arms 12, 15 of which are connected by links 16, 23 to arms 17, 24 on rock-shafts 18, 25 bearing arms 19, 26 co-operating with an abutment 20 carried by the armature of magnet 22. Rollers 28, 29 on stop arms 6, 7 co-operate with arms 11, 14 of levers 8, 9 to tension springs 31, 32, the arrangement being such that when one stop arm 6 abuts against arm 10 roller 29 on the other stop arm 7 engages arm 14 to tension spring 32 and rock shaft 25 so that arm 26 is clear of abutment 20, against which arm 19 associated with lever 8 rests. If an impulse is received, abutment 20 releases arm 19 thus permitting spring 31 to withdraw arm 10 from the path of stop 6 leaving the type-wheel spindle free to rotate until stop 7 engages arm 13. A similar cycle of operations occurs when the magnet 22 is de-energized.

Title: Improvements in the process of desulphurizing iron and steel
IPC: C21C1/02
Filed: 1921-04-28
Abstract: 162,618. Koppers, H. April 28, 1920, [Convention date]. Drawings to Specification. Purifying and refining.-In a process for desulphurising iron and steel, the iron bath is freed in the usual manner from phosphorus, manganese &c. and the slag layer is removed and replaced by a new layer of highly basic slag into which carbon, having approximately the same specific gravity of the slag, is immersed for the purpose of converting in a neutral atmosphere the sulphur into calcium sulphide and at the same time removing the last traoes of oxygen in the form of carbon monoxide. The carbon is prepared by overheating coke, drying and burning, grinding finely and mixing it with tar, the mixture being formed under great pressure into blocks provided in some cases with perforations. When required the slag bath is regenerated, after the molten iron has been removed, by passing a current of air over or through the slag.
