Title: Layout data processor for integrated circuit
Inventor: OE RYOICHI
IPC: G06F17/50
Filed: 1989-01-04
Abstract: PURPOSE:To easily convert even the line data of an optional angle into the loop data by providing the 1st and 2nd line shift means and an intersecting point calculation means. CONSTITUTION:A 1st line shift means 1 shifts a straight line Lij passing through the dividing points Pi and Pj in the vertical direction by the line width S1 and a straight line Ljk passing through the dividing points Pj and Pk in the vertical direction by the line width S1 respectively. An intersecting point calculation means 3 calculates the intersecting point Qj of two straight lines. A 2nd line shift means 2 shifts a straight line L12 passing through an end point P1 and a dividing point P2 by the width S1 and produces a virtual segment LX1 which is orthogonal to the straight line via the point P1 to shift the line LX1 in the vertical direction by the projecting width S2. Then the means 3 calculates an intersecting point Q1 between the shifted straight line and virtual segment. The line data is converted into the loop data when those calculated intersecting points are connected to each other.

A control arrangement for a stator winding machine having an evaluation device 14 connected to a drive 5 and a winding control device 6 such that signals are transmitted to the drive 5 and device 6 from a programmer 10 and a meter 11 each connected to the evaluation member, is characterized by at least a part of the signals being transmitted from the evaluation device to the programmer and to the meter. In operation the number of turns and the winding speed for the first winding step are selected and the drive 5 is switched on, whereupon the meter 11 begins to register. Before all the turns of the first winding step are inserted the drive 5 is switched to a lower speed. When the full number of turns have been wound, the winding step is changed by a regulator 7 and the turns are registered by one of one or more additional meters 18. Selection of the number of turns and winding speed and the change of drive 5 to full winding speed are then effected. The second and third winding steps are then similarly carried out in succession and on completion of the third step, the drive 5 is stopped. The winding step is changed again by the regulator 7, the winding plane and winding stroke adjusted by means of regulators 8, 9 respectively, the plane being registered by the other additional motor 18, and the number of turns and the winding speed selected for the first winding step in the second winding plane. When the third winding step is completed, the drive 5 is stopped, the winding step, plane and stroke are changed by the regulators 7, 8, 9 respectively and the control arrangement switched off.

Abstract: 1,199,011. Testing circuit breakers. ENGLISH ELECTRIC CO. Ltd. March 8, 1968 [Jan. 3, 1967], No.213/67. Heading G1U. A circuit breaker 14 is tested on making and breaking by a series current injection technique, in which high voltage from a charged capacitor 21 is applied to the breaker in addition to a low alternating voltage from a source 10 (applied through transformer 11). The breaker is closed at the maximum value of the resultant test voltage with the capacitor charged in one polarity and is opened at the opposite maximum value, after the capacitor has been charged to the opposite polarity by being temporarily connected across the inductor 18 by firing the spark gap 16 and then closing the breaker 15. The test breaker is subjected while closed to a heavy current at the low voltage through the closed breaker 15. When the breaker 15 is closed the voltage on the capacitor 21 reverses by oscillation with the inductor 18. At the appropriate point in the cycle, the breaker 19 is opened so that the capacitor remains charged in the reverse direction. Breaker 19. is subsequently closed and the test breaker is then opened at a reverse voltage maximum in the test voltage cycle. Prior to this make-heavy current-break test, a heavy current may be fed through the test breaker under low voltage condition from the source 10.

Title: Production of benzene hexachloride
IPC: C07C17/02
Filed: 1948-01-07
Abstract: Benzene hexachloride enriched in g -isomer is prepared by treating liquid benzene with chlorine in presence of actinic light at a temperature in the range 15-40 DEG  C., discontinuing the chlorination after 20-50 per cent by volume of the benzene has been converted to benzene hexachloride, separating solid phase material from the solution at a temperature which is correlated with the extent of chlorination, and then recovering the g -isomer enriched product from the solution without further chlorination. When the extent of chlorination is 20 per cent the separation temperature used is 0 DEG  \sB 10 DEG  C., when the extent is 50 per cent the separation temperature is 30 DEG  \sB 10 DEG  C., and these two conditions should be maintained in a linear relationship for intermediate values.  In the examples: (1) the extent of chlorination was 43-45 per cent and the separation temperature about 25 DEG  C.; (2) the extent was 20 per cent and the separation temperature 0 DEG C.; the chlorination temperature in both cases was just below 40 DEG C.  The Specification as open to inspection under Sect. 91 comprises a process in which an inert solvent may be present in the reaction and in which higher separation temperatures and lower chlorination temperatures may be employed.  An example is given of the process employing acetic acid as solvent.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,204,181. Separating propylene and propylene oxide. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 Dec., 1967 [4 Jan., 1967], No. 576/67. Heading B1L. Propylene oxide is recovered from mixtures thereof with propylene by preferentially absorbing the propylene oxide in propylene glycol, or in a liquid ester or ether thereof, and subsequently recovering the propylene oxide from the liquid phase. Thus, propylene, air and acetaldehyde are passed by lines 11, 12, and 13 respectively to reactor 1, from which there leaves a gas stream 15 comprising 1% propylene oxide and 58 % propylene, and a liquid stream 16 comprising 13.5% propylene, 1% propylene oxide and 76% propylene glycol and derivatives thereof which are also formed in the reaction. The gas stream passes to condenser 2 where a liquid stream 22 comprising an aqueous solution containing inter alia 1.5% propylene oxide is recovered and distilled to yield propylene oxide. The gas stream 21 passes to scrubber 3 where it is contacted in countercurrent with reaction products which boil above 140‹C. The bottoms pass with the liquid stream 16 to still 5 where propylene is distilled off at 23, leaving propylene oxide to be recovered in known manner from bottoms 24. Overhead from scrubber 3 passes to similar scrubber 4 operated at high pressure e.g. at 75 atmos and at 20‹C., waste gas being vented at 20 and propylene recycled by 19.
