IPC: H04Q3/545
Filed: 1971-04-19
Abstract: 1304486 Automatic exchange systems SIEMENS AG 19 April 1971 [13 March 1970] 23725/71 Heading H4K In an alternative routing strategy the network centres are given co-ordinates x and y corresponding to the nearest integral valued co-ordinates of a rectangular grid on the geographical map of the network, the links between centres being given co-ordinate parameters indicating the co-ordinate displacement of the centre from the centre to which each link gives access, an originating centre to destination centre route being plotted by computing the co-ordinate values of the displacement of the originating centre from the destination centre and link-by-link for each projected available route computing the algebraic residual displacement co-ordinates from the destination, the scalar values of such residual displacement co-ordinates, x and y, being added together as an estimate of residual distance so that, in comparison of one projected route with another, a choice of shortest route may be made. As a further criterion in route choice, and as a means of choosing between equal least residual distance values, the co-ordinates of a last centre on a projected route, the co-ordinates of a next centre in a proposed extension of that route, and the co-ordinates of the destination centre, are used to compute the area of the enclosed triangle taking the centres in that strict order in the determinant for the calculation. Such a computation effected for each projected extension of a route by one more link, indicates by the sign of the calculated areas whether the extension effects a divergence to the left or right from the direct route to the destination centre. If three such computations on successive extensions proposed for a route all have the same sign, and the residual distance factor for the last centre is not higher than the lowest of all such comparable factors in all projected routes, such projected route is preferred. When an area calculation for a triangle produces a zero result because the co-ordinates lie on a straight line, or because the last link of the projected route reaches the destination centre, the sign of the calculation is taken as positive or negative whichever is required to make up a set of three consecutive results of the same sign. The inter-centre links may be radio links.

Title: Improvements in the manufacture and production of potassium bicarbonate
IPC: C01D7/18
Filed: 1931-08-24
Abstract: Potassium bicarbonate is obtained by the reaction of potassium chloride with carbon dioxide or compounds of carbon dioxide and ammonia in mixtures of ammonia and water containing at least sufficient water to hydrolyse the carbonate to bicarbonate, but more ammonia than can be dissolved in the water present at room temperature and atmospheric pressure, at temperatures at which potassium carbamate would be decomposed under the conditions of working.  Temperatures between zero and 80 DEG  C. may be employed depending in the amount of water present.  The pressure should be preferably between 5 and 10 atmospheres.  According to one example, liquid ammonia, water and powdered potassium chloride are placed in a pressure vessel to which carbon dioxide at 10 atmospheres and room temperature is introduced.  The solid component consisting of potassium bicarbonate with some potassium chloride is separated from the mother liquor and is washed with a mixture of liquid ammonia and water.  Ammonium chloride may be recovered from the mother liquor. According to a second example powdered potassium chloride and ammonium bicarbonate are placed in a pressure vessel and a mixture of liquid ammonia and water is led through at a pressure of 25 atmospheres at 60 DEG  C. with stirring. Pure potassium bicarbonate and a mother liquor containing ammonium chloride are obtained.  Other ammonia-carbon dioxide compounds such as ammonium carbonate or carbamate may also be used.

Title: Improvements in and relating to the manufacture and production of artificial threads, filaments and the like
IPC: C04B35/49
Filed: 1933-09-04
Abstract: In a process for producing a cake of artificial thread which has practically uniform dyeing properties, viscose is supplied to spinning nozzles at a constant rate, and the thread is drawn through the spinning bath at a constant rate by means of a godet rotating at constant velocity, and then the thread is passed over one or more further godets of which at least the last from which the thread descends into the spinning box rotates at an increasing speed either during the formation of the whole of the cake or at least during the formation of the latter part thereof.  The increase in speed is desirably greater when the cake is subsequently dried and treated as a cake than when it is rewound into the form of a hank.  For instance, when the cake is to be wound into a hank before drying, the speed of the godet may be increased by 1,5 or 2 per cent during the formation of the thread while the increase may be 5 per cent when the thread is to be dried in the form of a cake.  The increase may take place more rapidly towards the end of the spinning, and the increase may commence a short time after spinning has started.

A multi-lens optical system comprises a first sheet of transparent material 6 with lenticular recesses 9 in its surface, a second transparent sheet 7 of material defining cavities with the recesses 9 in the first sheet and a fluid 8 in the recesses forming lenses having a different refractive index from either of the sheets. The density of the lenses, which have a radius of curvature of about 25 microns or smaller, may be as great as 1 million per sq. in. The first sheet base member 6 may be composed of thermosetting or thermoplastic resins or preferably glass; examples are given of preferred glasses. Isolation of the lenses is achieved by means of an opaque apertured plate 11 which can be made of chromium or plastics. The fluids may be liquids or gases and may be clear or coloured to act as a filter. Examples are given of preferred liquids. The bottoms of the recesses 9 are spaced from a plane surface 26 Fig. 9, a distance FL substantially equal to the focal length of the lenses. The apertured plate 11 has openings AD with a diameter smaller than that LD of cavities 9 and centred over these cavities. The lens system is used for the manufacture of photographic masks and for the direct exposure of photo-resist coated semi-conductor wafers in the manner described in Specification 1, 003, 897. In another embodiment Fig.14A, 14B (not shown) a transparent base (6A) with recesses (9A) filled with refractive fluid (8A) is attached to a cover lens 7A which is coated with a chromium layer (170) by evaporation. This layer is treated to form apertures, or a developed photo-resist layer may be used as the apertured plate. In a further embodiment Fig.15 (not shown), a basic unit comprising a base member (6B) with an optional apertured plate (11B) and a cover lens member (7B) encasing lenticular recesses (9B) filled with a refractive fluid (8B), has a second optional apertured plate (7C) and a second base member (6C) with refractive fluid, fixed to the exposed face of cover lens (11B).

The member 11 and disc 12 are biased, in opposite directions, by weights 23 and 17 respectively, the switch 16 being almost immediately actuated when the disc 12 rolls on the bar 24. The switch 16 and arm 15 move together until the stop 19B comes on to abutment with an adjustable stop 20 on the mounting plate 1 whereafter the disc 12 slips on the bar until the expiry of a predetermined extent of drilling set by a timing switch (not shown). The latter initiates the withdrawal of the drill with subsequent reversal of the movement of the bar, the disc 12 rolling on the bar until the starting position is reached. A reversing switch (not shown) is actuated when the drill is completely clear of the workpiece and the fast approach is then effected until the switch 16 is once again operated. The successive movements of the drill are effected until the whole drilling operation is completed. The drill may be mounted in the turret of a lathe the traverse of which is controlled by the mechanism described.
