Title: Digital machine of the optimizer type
IPC: G06Q10/00
Filed: 1974-05-14
Abstract: 1451881 Optimum path determination CYBCO SA 14 May 1974 [14 May 1973 14 Dec 1973] 21287/74 Heading G4A In an arrangement for determining the optimum path between an initial system state D and a final point A a plurality of memory and computational cells are used to simulate the propagation of a backward wave from state A to state D the contents of each cell during the operation representing the difference in the number of steps required to reach a corresponding system state on the dummy backward wave with constraints (forbidden states) imposed as compared with a reference wave with no imposed constraints. The amount of storage required is reduced by providing only one cell per diagonal vector (2N cells instead of N<SP>2</SP>) and by storing differences instead of absolute values in the cells. In one embodiment the centre and lower diagonal address cells are initially set to 0 and the remaining cells for successive upper diagonals are set to increasing values 1, 2, 3 .... to represent the difference between the number of steps to reach each cell for a linear wavefront and a rectangular wavefront the apex of which travels along the centre diagonal. To process each constraint, the contents of cells within the bounds of the upper and lower diagonal for that constraint are given successively increasing values up to the value stored in the cell for the upper diagonal. The process is repeated for each constraint and the contents of the cells then represent the delay of the disturbed (constrained) rectangular wavefront with respect to the undisturbed wavefront. The first step on the optimum path is then taken from the final state A to one of the adjacent states A', A", A"' in the backward direction having the lowest stored value. The entire process is repeated taking the selected state A', A" or A"' as the starting point for the backward wave. In another embodiment a modified procedure is used whereby each cell stores a single bit which represents the incremental difference between the notional contents of the cell in the first embodiment and the notional contents of the cell corresponding to the preceding diagonal address. After all constraints have been processed the sum of the 1 increments up to the three states A', A", A'" represents the delay of the disturbed wave as before. Details of suitable micro-programmed hardware for the two embodiments are given together with an explanation of how the process can be extended to deal with problems in more than two variables. Application to air and rail traffic control is mentioned.

Title: A process for refining fats, fatty oils, waxes and the like
IPC: C11B3/06
Filed: 1932-08-02
Abstract: Fats, fatty oils and waxes are refined by treatment with alkylolamines mixed or not with liquid ammonia; an alkylolamine soap is preferably added to the amine when the free fatty acid content of the material treated is low.  Mono-, di-, and tri-ethanolamines or mixtures thereof are preferred for refining vegetable oils, may be by countercurrent treatment.  In an example, raw cottonseed oil is treated at 40 DEG  C. with \ba1/3\be vol. of monoethanol amine and the mixture allowed to settle.  The oil layer is separated and is freed from any amine by heating in vacuo and blowing an inert gas therethrough, or by washing with water.  The amine is recovered from the solution of fatty acids, colouring matter and other impurities by distillation, preferably under an absolute pressure of about 25-30 mm. and with steam at about 120 DEG  C., the vapours being passed through a rectifying column to separate the amine from condensed steam.  Coco nut oil is treated at about 35 DEG  C.

Convention date, Oct. 23, 1930. [Class 38 (iii).] The effect of variations of the power supply U on the phase of rotation of a television motor M, synchronized by currentfrom a separate source S, is decreased by supplying an electromagnetic braking couple from the power supply, which braking couple is large compared with the frictional resistances. The motor M, consisting of a synchronous motor supplied from the source S, and a driving motor supplied from the supply U, either combined or mounted as separate units on a common shaft, drives a metallic disc D, which may be the scanning disc, which disc is subjected to the action of an electromagnet B energized from the supply U. A converter C is provided if the nature of the driving element of the motor M, and the supply U are different, and an iron resistance R in hydrogen protects the system against slow variations of large amplitude. With an alternating current supply U, the coil B may be shunted by saturated inductances, or it may be replaced by, or combined with, a double winding which generates a driving torque below a certain speed and a braking torque above that speed, an adjustable resistance being connected in series with one part of the double winding for adjusting the phase.
