IPC: H02P5/48
Filed: 1929-02-06
Abstract: 305,668. Siemens - Schuckertwerke Akt.-Ges. Feb. 10, 1928, [Convention date]. Differential governors.-Continuouscurrent motors 3, 4, and 5 driving different units of a paper-making machine are controlled for equal or proportional speeds by respective differential gears 9 and sections of a master shaft 10; the respective sections of the master shaft being connected end to end through differential gearing 20, and driven by a motor 6. Auxiliary motors 21 are geared to drive the housings of the gears 20 so that an adjustable speed may be added or subtracted between the various sections of the master shaft. In a modification the motors 21 are not used, the housing of the gears 20 being driven by cone pulley gearing from a second master shaft which is driven by the motor 6. In a further modification the cone pulleys carried by the second master shaft in the first modification, are each carried on a separate shaft which is driven by a belt from the corresponding section of the main master shaft.

Abstract: 163,121. Cilley, I. J., and Cilley, V. I. Feb. 12, 1920. Rotary cylinder apparatus.- In a turning and stopping signal apparatus of the kind having a drum bearing the required symbols and rotatable within a casing to display the desired indication through an aperture, the stopping signal is given by a cam and lever transmission operated by the brake pedal, and a separate lever-operated control is provided to give the other signals independent of the brake pedal. The drum 17 bearing arrow or other indications, preferably in stencil or transparency form and illuminated at night by a lamp 16 which also serves to illuminate the number plate 38 through an aperture in the bottom of the casing 1, has end thimbles, on one of which is a spring 9 serving to return the drum to normal position, and round the other passes an operating-cable 8. This cable is connected through a turn-buckle 34 and cable 33 with a lever 24 pivoted at 25 and provided with a pin which passes through a slot 31 in a supporting bracket 18 and carries a roller 30 engaging the cam surface of a segment 20 pivoted at 21. The cam segment is connected by a rod 23 with the brake rod 44, so that when the pedal 43 is depressed, cam 20 and lever 24 are moved to display the " stop " signal through the window 3 of the casing 1. A separate lever 52, which may be hand-operated and passes through an adjustable gate slot in the floor 49, is pivoted at 27, and has an arm 26 with a pin-and-slot connection with lever 24, so that lever 52 can be used to operate the signal drum, but brake-operation of the lever 24 does not move lever 52.

Patent GB-600191-A (GB)
Title: Improvements in and relating to fuels used in internal combustion engines
IPC: C10L1/26
Filed: 1944-03-09
Abstract: Corrosion in internal-combustion engines is avoided by employing a fuel comprising principally petroleum hydrocarbons and containing dissolved or suspended therein an alkyl ester of a sulphur-free acid of phosphorus.  Suitable esters are the alkyl esters of phosphoric or phosphorous acid, such as trimethyl, triethyl or tributyl phosphates or phosphites or the corresponding mono- or di-esters.  Salts of the esters, particularly organic base salts such as diethyl amylamine phosphate may alternatively be employed.  The esters or their salts may be incorporated in a vehicle consisting of a glyceride, wax, ester or fatty alcohol, e.g. cetyl alcohol, cholesterol, lanosterol or mixtures thereof, and the composition added to the fuels.  Where the vehicle is suitable for use as an upper cylinder lubricant, small gaseous or vaporous inclusions may be incorporated in the composition, thereby producing a lubricant of the character claimed in Specification 460,345.  The fuel employed may contain tetraethyl lead with or without organic halides such as ethylene dichloride or ethylene dibromide.  Alternatively, the tetraethyl lead with or without organic halides may be added to the alkyl ester-vehicle composition.

Patent GB-415055-A (GB)
Title: Improvements in yarn manufacture
IPC: D01F2/28
Filed: 1933-02-15
Abstract: The process of the parent Specification for obtaining artificial filament yarns resembling staple fibre yarns, which consists of stretching a bundle of filaments in a softened state so that individual filaments are broken, is applied to the production of regenerated cellulose yarns.  The process may be carried out with filaments obtained by the viscose, cuprammonium, or nitrocellulose processes, or to filaments of organic cellulose derivatives by saponification of the yarns obtained by the process of the parent Specification or by saponification of continuous filament yarns of cellulose esters and stretching in a softened state during or subsequent to saponification.  The process may be carried out at any stage of the production of the filaments, or it may constitute a separate operation.  The yarns may be treated in hanks or other packages, or while travelling, or while in warp formation.  They may be treated before or after twisting.  The degree of softening is preferably such that the filaments undergo a high degree of elongation before the requisite breakages in the bundle have been attained.  The softening agent may be sulphuric acid, caustic alkali, zinc chloride, or a thiocyanate.  The yarn may be subjected to a gassing operation to remove superfluous projecting ends, or it may be passed over a roughened surface to produce increased hairiness.  The yarns may be subjected to after-treatments such as delustring, mordanting, or shrinking. They may be doubled together or with other yarns.  They may be employed in woven or knitted fabrics, and may constitute the whole or part of such fabric.  The warp or weft may comprise normal or imitation spun yarns of regenerated cellulose, the weft or warp comprising normal or imitation spun yarn of cellulose acetate.  In an example, cellulose acetate yarn is passed through an aqueous solution of dioxane and stretched between rollers.  The yarn is allowed to slip on the take-up roller so that individual filaments are broken, but not the yarn as a whole.  The yarn is washed, dried, twisted, and converted into regenerated cellulose yarn by passage through caustic soda solution containing sodium chloride. In another example, viscose yarn is passed through strong sulphuric acid solution and stretched.  In another example, cuprammonium cellulose solution is extruded into a precipitation bath and the thread obtained is stretched between the spinning funnel and the hardening bath by rollers so that individual filaments are broken.  The yarn is subsequently hardened, shrunk, washed, and twisted.
