Inventor: ROHDE LARS
IPC: G06Q40/00
Filed: 1996-02-15
Abstract: Method and data processing system for determining the type, the number and the volume of financial instruments for funding of a loan with an interest rate adjustment with an equivalent proceeds to a debtor, the loan being at least partially refinanced during the remaining term to maturity of the loan. In the data processing system, data are loaded, which data indicate the principal of the loan, the term to maturity of the loan, the profile of repayment, and a desired/intended profile of refinancing. Furthermore, data are loaded, which data indicate requirements as to maximum difference in proceeds, maximum difference interest rate, and maximum difference in balance between on the one side the creditor and on the other side the debtor. On the basis of these data as well as a first guess at an interest rate, the volume of a number of financial instruments to be applied for funding of the loan is calculated. The results of the calculations can be applied by the debtor, for instance a financial institution such as a mortgage credit institution, to secure that the loan is funded in such a way that interest rate risks such as imbalance in the payment flow is avoided or minimized. By applying the results of the method according to the invention, the creditor has the possibility of creating a hedge between lending and funding.

Filed: 1936-08-04
Abstract: 479,485. Automatic volume control. JOHNSON, G. W. (Philco Radio & Television Corporation) Aug. 4, 1936, No. 213/38. Divided out of 479,440, [Group XL]. [Class 40 (iv)1 [Also in Group XL] In an audio-frequency amplifier with degenerative feedback from the output to the input, the feedback path includes impedances, one of which is variable slowly with time in dependance on current flow. The Figure shows an amplifier V2 with the tungsten filament of an incandescent lamp R3 in series with resistances Rl, R2 so that volume expansion is obtained. Since feedback is taken from resistances R1, R2 volume expansion is obtained. If the lamp is used in place of R] volume contraction is obtained, or if a lamp with a negative temperature coefficient is used in place of R1 volume expansion is obtained. Alternatively, both types of lamp may be used, one for R1 and the other for R3 to give expansion or contraction of volume. The amplifier may be frequency selective by including impedances varying with frequency, e.g. condenser C1 in the feedback path, and be associated with a detector to which feedback is applied as described in Specification 479,440.

Patent GB-826557-A (GB)
Title: Production of aminodiboranes
Inventor: HUFF GEORGE FRANKLIN
IPC: C07F5/00
Filed: 1956-01-10
Abstract: Aminodiboranes R2NB2H5 are prepared by reacting an amine-borine of the formula R2NH : BH3, where R is an alkyl radical or hydrogen, and both R's may be the same or different, and a non-protonic acid of the Lewis type in proportions of 2 mols. of the former to 1 of the latter, and then separating and recovering from the reaction products the aminodiborane thus formed.  The amine-borines used may be primary amine-borines, e.g. CH3NH2 : BH3, secondary amine-borines, e.g. (CH3)2NH : BH3, and also diborane diammoniate which may be represented as NH3 : BH3.  The preferred Lewis acids are boron trifluoride and aluminium trichloride, but other examples mentioned are silicon tetrachloride, phosphorus pentoxide, sulphur dioxide, thionyl chloride and sulphuryl chloride.  The reaction conditions are not critical but it is preferred to effect the reaction under elevated temperature and pressure while avoiding temperatures which would cause decomposition of the product.  The amine-borine starting materials may be produced by reacting diborane and an amine at low temperatures.  Dimethyl amine-borine may be produced by electrolysing a solution of an ionic borohydride, e.g. sodium borohydride, in dimethyl amine, using an inert anode and a mercury cathode, as described in Specification 826,558.  In examples: (1) dimethylamine-borine and BF3 in a 2: 1 mol. ratio are held at 100 DEG C. for 12 hours in a sealed tube and the tube is then opened and the dimethyl aminodiborane separated from other products; (2) aluminium chloride is used to replace BF3 in the above example.  A comparative example describing the use of hydrogen chloride shows that no aminodiborane is formed.

[Classes 38 (ii) and 38 (iv).] In an inverter or frequency changer means are provided for maintaining the potential of the A.C. output equal to and in phase with the potential of a control circuit 21. A series type inverter connected to the A.C. mains 12 is supplied by a D.C. generator 11 the potential of which is controlled by means of a rheostat 33. The circuits 12, 21 are interconnected through the windings 31, 33 of differential potential and phase relays 32, 34. The relay 32 has a winding 35 connected to the leads 29, 30 through a condenser 36 so that the relay responds to phase difference to complete the circuit of a reversible motor 28 which adjusts a phase-shifting 'transformer supplying grid potential to the inverter. The relay 34 has a winding 38 connected to the leads 29, 30 through a resistance 37 so that it responds to difference of potential to complete the circuit of a reversible motor 50 which adjusts the rheostat 53. Fig. 2 shows a frequency changing arrangement in which an inverter 15 is supplied from a rectifier 62. The circuits 12, 21 are interconnected by a circuit 30 containing in series a condenser 94 of low impedance and a resistance 72 of high impedance shunted by transformers 91, 73. Difference of potential in the circuits 12, 21 causes a current to flow in the circuit 30 which by means of the valves 76, 77 controls the current supplied, by the valves 70, 71 to the saturating windings of a choke 68 in the grid circuit of the rectifier 62, so that the phase of the grid potential is altered to give correction for potential difference. Phase difference causes a current to flow in the circuit 30 which by means of the valves 85, 86 controls the current supplied by the valves 82, 83 to the saturating winding of a choke 81 in the grid circuit of the inverter 15 to give correction for phase difference.

[Class 35] [Also in Group XXXVII] In the speed control of A.C. commutator motors 5 by means of an induction regulator A, B, C: D, E, F, transformer or auxiliary stator winding for forward running, and the dynamic braking of the motor by a reverselyconnected additional winding D1, E1, F1 on the induction regulator, the supply circuit to the motor is broken at the main switch 1 by the action of the relay P1 when its operating coil 9, 21 receives full energization on the motor coming to rest after braking. Inadvertent reverse running of the motor is thus avoided. The arrangement without the relay is described in Specification 484,413. To stop the motor, the switch 7 is. moved to the open position thereby de-energizing the operating coil of the change-over switch 2 which moves over to disconnect the forward running regulator and to connect the braking regulator. At the same time the back contacts 20, 21 of the switch 2 close and when the motor slows up sufficiently, the potential across the coil 9, 21 of P1 becomes adequate to cause its operation, thereby breaking at 11, 15 the circuit (through the interlock contacts 1) of the operating winding 1 of the main switch.
