Title: Improvements in or relating to paper reeling machines
IPC: B65H19/22
Filed: 1926-10-07
Abstract: 271,710. Okuura, W. Oct. 7, 1926. Feeding webs.-In a paper-reeling machine provided with winding-reels 1, Fig. 1, mounted on a rotatable frame 4 so as to be brought successively into the working or winding position, each of the reels is directly coupled to an induction motor 6, the rotor of which is electrically connected to the stator of a braking or balancing motor when the reel comes into the working position, thereby regulating the winding speed and the tension of the web. The reels 1 consists of perforated hollow cylinders on shafts 2 mounted on the frame 4, which also supports the motors 6, and the ends of the reels opposite to the motors are adapted to be connected to an air suction pipe when brought into the winding position, so that the free end of the web severed from the preceding reel is caused to adhere to the reel to start a fresh roll, the severing of the web being effected automatically in known manner. The shaft 3 carrying the frame 4 is geared to an intermittently running motor 12, which is automatically switched on in known manner when a wound roll reaches a predetermined size, thereby rotating the frame to bring the next reel into position. Since the vacuum is required only when a new reel begins to rotate, the motor 12 may also be used to drive the vacuum pump 20. A series of stationary rings 14 concentric with the shaft 3 connect the stators of the reel motors 6 to the current supply and connect their rotors to the stators of the balancing or braking motors 13a, 13b, the arrangement being such that the motor 13<a> is connected to the rotors of the motors A-A<2>, Fig. 3, by a set of three slip rings c, and the motor 13b is connected to the rotors of motors B-B<2> by slip rings b. Slip rings a connect the stators of all the reel motors to the three-phase supply i. Five-sixths of the periphery of each slip ring has an insulating coating, the uncovered portions of the surfaces of all the rings being disposed in the same axial. direction to make contact with brushes on the connecting leads of a reel motor when it is in the winding position W. The motors 13<a>, 13b are loaded by friction brakes 10 and blowers 9, the load of which can be varied according to the winding speed desired.

Title: Improvements in morpholine emulsifying agents
Filed: 1937-09-16
Abstract: Emulsifying agents particularly for making aqueous emulsions comprise the reaction products of morpholine, or highly basic, water-soluble addition and substitution products thereof, with fatty acids or aliphatic derivatives having an acid reaction.  The morpholine derivatives are those of which the boiling points or the boiling points of their aqueous solutions lie between 90-150 DEG  C., e.g., N-methyl morpholine; N-ethyl morpholine; 2.6 dimethyl morpholine; N-ethoxy ethyl morpholine and N-vinoxy ethyl morpholine, and they may be combined with oleic, palmitic, stearic, ricinoleic and other fatty acids and the higher alkyl derivatives of acetic and sulphuric acids. On standing, especially in the presence of water, the morpholine base is gradually released from the products.  The common waxes, oils, fats, hydrocarbon liquids and substituted hydrocarbons are readily emulsified preferably in a volatile aqueous phase.  Examples (1) and (2) describe emulsions of, paraffin olive oil, naphtha, ethylene dichloride kerosene, beeswax and carnauba wax, which are prepared either by dissolving the amine in water and adding the mixture of oil and fatty acid with agitation or by heating together the amine, water and fatty acid and then adding the oil or melted wax.  Examples (3) and (4) describe rubless polishes formed by emulsifying carnauba wax with oleic acid, morpholine or N-methyl morpholine and water, with the addition of a little borax if desired and then adding shellac, morpholine and additional water to the hot emulsion which is then allowed to cool.ALSO:Emulsifying agents comprise the reaction products of morpholine, or highly basic water-soluble addition and substitution products thereof, with fatty acids or aliphatic derivatives having an acid reaction.  Suitable morpholine p derivatives include N-methyl morpholine ; N-ethylmorpholine ; 2,6 dimethylmorpholine ; N-ethoxethylmorpholine, and N-vinoxyethyl morpholine, and they may be combined with oleic, palmitic, stearic, ricinoleic and other fatty acids, and the higher alkyl derivatives of acetic and sulphuric acids.  On standing, especially in the presence of water, the morpholine base is gradually released from the products.

Title: Chopper circuits

Filed: 1971-04-19
Abstract: 1342514 DC-DC converters HITACHI Ltd 19 April 1971 [27 March 1970] 25431/71 Heading H2F [Also in Division H3] A chopping circuit (Fig. 2) comprises a first compound thyristor (Fig. 1a) MCRf connected in series with a saturable reactance SLM and a further compound thyristor ACRf, connected in series with a further saturable reactance SLA and energy storing means to commutate said first thyristor (A compound thyristor is similar to a normal thyristor 1 in that it has four layers P-N-P-N, the inner two of which pB and nB (Fig. 1a) are extended and respectively connected to the anode A and cathode K electrodes of the thyristor. Thus the thyristor 1 has a diode 2 of opposed polarity in parallel with it.) Although the compound thyristor switches off quickly due to current flowing through the diode causing the withdrawal of residual carriers in junction J 3  of the compound thyristor, stored charge in the diode causes the thyristor 1b turn on again when forward voltage is reapplied. The saturable reactors overcome this by limiting the rate of charge of current through the diode region 2 and the rate of change of applied forward voltage to the thyristor. When voltage is applied to the circuit of Fig. 2, the capacitor Co charges to the polarity shown via the diode region of thyristor ACRf. Thyristor MCRf is then fired, saturable reactance SLM saturates positively and current flows through MCRf. Thyristor ACRf is then fired and capacitor Co discharges through a linear reactor Lo, positively saturates saturable reactance SLA and eventually discharges around the loop Lo, ACRf, SLA, SLM, MCRf and recharges to the opposite polarity. Co then discharges, SLA saturates negatively as the current through ACRf goes negative and eventually the current equals the load current through MCRf and the thyristor region of MCRf stops conducting, the diode region now passing the reverse current which causes SLM to saturate negatively. As the capacitor recharges positively, first SLM and then SLA change to nearly positive saturation and the sequence is then repeated. Surge absorbers CM, RM and and CA, RA help to limit across the thyristors and linear impedances  ZM and ZA, which may be either resistive or inductive, modify the B-H curve of the saturable reactances to simulate a larger value of H. The compound thyristor ACRf may be reversed, in which case it is fired first in order to charge Co and suitably for Co to discharge postively in the above sequence of events. Current sharing of several thyristors MCRf is accomplished by using a balancetransformer AB, Fig. 9, and individual saturable reactances SLM<SP>1</SP>1, SLM<SP>1</SP>2 and SLM. If the balance transformer is adequate for balancing, either SLM or SLM<SP>1</SP>1 and SLM<SP>1</SP>2 may be dispensed with. A plurality of such choppers may be used in series.
