Title: Means for controlling lifts, hoists and the like
IPC: B66B1/36
Filed: 1927-07-01
Abstract: 273,752. Siemens - Schuckertwerke Ges. July 2, 1926, [Convention date]. Electric push-button systems. - In a pushbutton lift system an, auxiliary regulator connected in series with the speed regulator and short circuited during normal starting and running is brought to the " off " position when the lift has been stopped in. order to make it possible to close the motor cut-outs by the starting pushbuttons and then brings the lift back to its normal speed by gradually short-circuiting again. The hoisting motor 11 is coupled to a starting dynamo 12, the field of which is in circuit with a speed regulator 13 positively controlled by the lift and an auxiliary regulator 14. When the constantly switched in regulator 13 is set to the smallest number of revolutions at 15, it closes contacts 16 which are connected in parallel to the contacts 17 of the regulator 14. The contacts 17 are closed in the " off " position of the regulator 14. The contacts 16, 17 close the circuit of the switching- in cut-out 18 from the bus-bar P through the switching-in push button E, cut-out 18, end switch 19 actuated by the lift, and the holding push-button H to the bus-bar N. The motor contacts 20 controlled by the cut-out 18 close the field circuit of the dynamo 12, and the contacts 21 close the holding circuit of the cut-out 18. In its working position the regulator 14 is shortcircuited so that when the button E is pressed, the cut-out 18 becomes operative and remains switched in through its contacts 21; the motor 11 starts and the regulator 13 varies the speed. If the lift is stopped between stopping places, the speed regulator 13 will be in some such position as 22 and the contacts 16 will be open. To start the lift the regulator 14 must be brought back to the " off " position to close the contacts 17. The cut-out 18 can then be switched in by the button E, but the lift will start only after the regulator 14 is moved into the working position and will be brought to the speed corresponding to the position of the regulator 13. The, auxiliary regulator may be controlled by the push-buttons in such a manner that at each stop outside a stopping place, it is brought automatically to the " off " position and at each start is brought automatically from the " off " position to the short circuiting position. The auxiliary regulator may be provided with slip rings through which passes the holding circuit of the motor cut-outs.

Title: Improvements in electric transformers
IPC: H01F30/10
Filed: 1934-10-26
Abstract: 442,282. Transformers. CLARK, H., Natal University College, Durban, South Africa. Oct. 26, 1934, No. 17575. [Class 38 (ii)] A transformer comprises a plurality of magnetic cores I ... 14, Fig. 1, arranged in one or more stacks and each carrying a winding, these windings being connected in series to form the high tension winding of the transformer, the low tension winding 18, 19, 20 linking with all the cores. The cores are insulated from one another and their potential is regulated by connecting each core with a winding 15, Fig. 3, associated with it. Alternatively, each winding 15 may be connected to a split metallic cover insulated from and enclosing the core or the portion of the core beneath the winding 15. Capacitances 27, Fig. 4, may be connected between the cores 1 .. 10 to regulate their potential under surge conditions, the core 1 being connected to terminal T1 directly or through a further capacitance. The capacitances 27 may be the inherent capacities between the cores 1 .. 10 and may be adjusted by adjusting the core spacing, core dimensions and the nature of the dielectric path between the cores. Alternatively, they may be separate added capacitances and may be provided by arranging a thin suitably insulated metallic sheath around each core, the sheath being so arranged that it does not form a short-circuited turn. If the high tension winding is connected between a transmission line and earth, the cores carrying the windings in nearest connection to the transmission line may be made larger than the remaining cores to provide greater clearance between the high and low tension windings. The flux density in these large cores may be made the same as that in the normal cores by adjusting the number of winding turns linking with the large cores. The low tension winding may be circular, the cores being arranged around and perpendicular to its circumference.

Title: Improved Process of Producing Alkali Carbonate and Hydraulic Cement from Alkaliferous Silicate Minerals.
Inventor: JUNGNER ERNST WALDEMAR
IPC: C01D7/00
Filed: 1916-12-08
Abstract: 103,290. Jungner, E. W. Jan. 7, 1916, [Convention date] Alkali carbonates.-Relates to a process for preparing alkali carbonates, in which Portland cement also may be obtained if desired, by heating an intimate mixture of a powdered alkaliferous mineral silicate, such as feldspar.or alkaliferous clays or slate, a powdered calcareous material, and finelydivided carbon or carbonaceous matter in an atmosphere containing carbon dioxide. The amount of carbon used is 4-10 per cent. of the weight of the raw mixture. If a large quantity of free silica is present in the raw materials, small quantities of iron oxide, for example iron ore, or substances containing a large percentage of alumina, for example bauxite, are added. A temperature of 1250-1400‹ C. is required, and whether or not cement is desired as a product, the operation is preferably conducted in a cement furnace. If a shaft furnace is employed, the mixture is briquetted, for example by moistening with slaked lime which has been puddled in water; and if the furnace is an electric one, it is necessary to supply carbon dioxide, or air if the amount of carbon in the charge is sufficient. Specifications 26497/12 and 28970/12 are referred to.
