Title: Improvements in and relating to electro-magnetic motor devices
IPC: H02K33/00
Filed: 1926-08-27
Abstract: 279,974. Moller, C. Gleerup-, and Baxter, P. Aug. 27, 1926. Motors with unwound iron armatures; brushholders. - A phonograph or other motor of the type in which either the rotor or stator consists of unwound iron with .projections which are attracted by intermittently energized and shortcircuited magnets is provided with switching means for connecting its magnet coils in series or parallel for running on continuous and alternating-current supplies respectively, a series resistance being included for alternating running. Means are also provided for altering the moment in the revolution at which the magnet coils are short-circuited to reduce sparking on the alternating-circuit supply. Fig. 2 shows a motor in which magnets 1 rotate within an unwound iron stator 2 and are intermittently short-circuited by a switch 5 rotating with the magnets and working in conjunction with a change-over switch connected as in Fig. 6 for grouping the magnet coils 4, 4 in series or parallel. The alternating or continuous-current supply is brought to terminals 10, 11 which are bridged by the short-circuiting device 5. In the position of the arms 7, 8 shown, the coils 4, 4 are in parallel for alternating-current running and the short-circuiter 5 is connected in series with a resistance 22 in shunt to them. With the switch as shown in dotted lines, the coils 4, 4 are in series for continuouscurrent working and are shunted by the shortcircuiter 5 without the resistance 22. The switch may be coupled to the brush-carrier 27, Fig. 7, to alter the short-circuiting axis for alternating current running or a similar effect may be obtained by working with fixed brushes and rocking the short-circuiting switch 5 on its shaft. This may be done by mounting the change-over switch on the disc 58, Fig. 2, of the rotor so as to rotate therewith and moving the short-circuiter 5 on its shaft by means of a pin 56 carried by one of the arms of the change-over switch and engaging the short-circuiting switch 5 so that the latter switch is turned on the shaft when the former is thrown over. An alternative method involves the use of three fixed brushes 42, 43, 44, Fig. 8, and connections to a 3-pole switch such that one pair of brushes functions for continuous and another for alternating-current working. The circuit leads terminate at 34, 36 and in the switch position shown the magnet coils 4, 4 are energized in parallel with alternating-current and the shortcircuiting is intermittently done by the brushes 42, 43 through the resistance 52. For continuouscurrent working, the switch is moved to the position shown in dotted lines and the brushes 42, 44 operate without the resistance 52. The magnet coils may be divided into two groups, one of which is permanently energized and the other intermittently short-circuited and the coils in each group and the groups themselves may be connected in series or parallel by a switch of the type shown in Figs. 6 and 8.

Patent GB-401627-A (GB)
Title: Improvements in the manufacture of alkali cyanides
IPC: C01C3/02
Filed: 1933-08-03
Abstract: Alkali cyanides are obtained by heating a mixture of an alkali thiocyanate with an oxide or carbonate of an alkaline-earth metal or heavy metal in the presence of carbon monoxide or gases containing carbon monoxide at 400-800 DEG  C.  The carbon monoxide may be employed in the form of producer gas, water gas, or a mixture of carbon monoxide with a hydrocarbon or ammonia.  The carbonates or oxides with which the alkali, e.g. sodium, thiocyanate may be mixed include zinc oxide, ferrous carbonate, burnt lime, and chalk.  The crude product obtained may be treated with a suitable solvent for alkali cyanide such as anhydrous ammonia or an amine, then another less volatile liquid capable of maintaining the accompanying impurities in solution, preferably a non-aqueous liquid such as alcohol, may be added.  Thereafter by evaporation wholly or in part the first-mentioned more volatile solvent, the pure alkali cyanide, may be obtained.  Alternatively, the second solvent may be mixed with the first more volatile solvent before or during extraction.  The extraction may also be carried out as described in Specification 382,372, a mixture of anhydrous ammonia with concentrated ethyl or methyl alcohol being used.  On evaporating off the ammonia, alkali cyanide crystallizes.  The mother liquor after resaturation with ammonia may be used for further extraction.

Filed: 1922-08-15
Abstract: 207,232. Hirst, J. A., and Brook, Hirst, & Co., Ltd. Aug. 15, 1922. Controllers, actuating; controllers with no-volt and overload release; controllers, multiple rocking bar.-In a motor starter comprising a circuitbreaker and separate accelerating switches operated in succession by a handle mechanism, the circuit breaker is held closed against springs or the like by a detent having mechanical connection with an overload device and also with a novolt device. The detent is also tripped automatically if the operating handle is released before it reaches the full-on position. Figs. 3, 4, and 7 show the invention embodied in an alternating current motor starter of the star-delta type having contacts in oil. Three vertically movable contact members, of which only the circuit breaker member C is shown in Fig. 3, are raised and lowered in succession by cams c<14> on a shaft F which is intermittenty advanced by a handle and ratchet mechanism, Fig. 4. The circuit breaker is closed by the first stroke of the handle, and is then held from falling open by a detent J catching a pin c<12>. A tripping-frame M, m<1>, Figs. 3 and 7, extending over three overload magnets o<1>, o<2>, o<3> is knocked up when any one of the magnets lifts its plunger o<4>, and is also knocked up by the fall of a plunger-rod n<1> of a no-volt magnet N. A further tripping action is obtained by spring- pressure through a bell-crank lever r<1>, r<2>, Fig. 4, which bears down upon an arm P mounted on the spindle K opposite to the frame M. The tripping action is prevented while the handle G is held in an operative position owing to a cam g<9> pushing out a rod g<10>, and is also prevented, irrespective of the position of the handle, when the revolving parts have reached full-on position, owing to a sprocket-wheel g<1> carrying a stud g<12>, where it blocks the throw of the bell crank lever r<2>. The tripping action due to the handle may be obtained in a different manner, e.g. by allowing the handle to actuate a switch in the, circuit of the no-volt magnet. Apparatus of like construction may be adapted to starters dependent upon tapped transformers and those dependent upon resistances in the rotor circuit. Diagrams of electric connections are given in the Specification. Modified apparatus in which air-break switches replace the oil-break switches is also described. Specification 166,256 is referred to.
