Title: Electrical discharge machining
IPC: B23H7/16
Filed: 1974-02-28
Abstract: 1449385 Electro-erosion INOUR-JAPAX RESEARCH Inc 28 Feb 1974 [3 March 1973 17 May 1973 12 Sept 1973] 9128/74 Heading B3V The duration of an electrical discharge machining pulse is dependent on the current across the machining gap defined by the workpiece 2 and the electrode 1. In one embodiment, the current across the gap G is monitored by a circuit 5, 5a which supplies an analog signal representing the magnitude of the current to a converter 7 (Figs. 2 or 6, not shown) which produces pulses of a frequency proportional to the analog signal. When a preset number of pulses has been counted by a counter 8, a gate circuit 10 is set causing a multivibrator 12 to be triggered and a power switch 4 supplying machining current to the gap G from a power source 3 to be turned off for the duration of operation of the multivibrator 12. If the gap current is high indicative of a short circuit, the pulse frequency will be high and the counter 8 will reach its preset count before a counter 14 counting pulses from an oscillator 13 reaches its count. As a result, a signal is applied to a delay circuit 17 to delay the reset signal to the gate circuit 10 so as to increase the erosion pulse interval. In another embodiment (Fig. 4, not shown) when the counter (108) reaches its preset count, a signal is applied to a flip-flop (110) to turn off the switch (104) and to a timer (112) which subsequently sets the flip-flop (110) to commence another discharge. In a further embodiment (Fig. 5, not shown) gap breakdown is effected by a high voltage power source (205) followed by a machining discharge from a source (203). When the counter (208) reaches its preset count, the power switch (204) is turned off and a signal applied to a counter (212c) to permit it to count pulses from a generator (212a). The switch (204) is held off until the counter (212c) has counted a preset count. The high voltage source (205) may be shunted from the machining gap G if the gap voltage falls below a predetermined value (Fig. 7, not shown).

Title: Organic isocyanates
Inventor: JOLLES ZVI ENRICO
IPC: C07C265/12
Filed: 1961-03-17
Abstract: The invention comprises diisocyanates of the formula:-<FORM:0971168/C1/1> in which X1 and X2, which may be the same or different, are hydrogen, chlorine or bromine. Preferred compounds are the 3,31-dibromo-, 3,31,5,51-tetrabromo-, and 3,31-dibromo-5, 51-dichloro-4,41-diisocyanato-diphenyl methane. The isocyanates may be made by brominating the corresponding 4,41-diisocyanatodiphenyl methane in the absence of actinic light to introduce at least one bromine atom into each of the aromatic nuclei. They may also be obtained by brominating the corresponding 4,41-di-amino-diphenyl-methane, the amino groups being protected by acylation during bromination, and then, after removal of the protective groups by hydrolysis, converting the amino groups to isocyanate by reaction with phosgene. Bromination is preferably effected in the presence of a halogen carrier, such as iodine, and an inert solvent, such as carbon tetrachloride at temperatures up to 100 DEG C.  The bromine-substituted product may be chlorinated or chlorination may precede the bromination.  The chlorination may be effected at temperatures up to 80 DEG C., preferably 10-30 DEG C.  An example describes the bromination of 4,41-diisocyanate diphenyl methane in carbon tetrachloride in the presence of iodine to give 3,31-dibromo-4,41-diisocyanato-diphenyl methane.ALSO:Polyurethane materials may be made from a mixture of diisocyanates including one or more of the formula: <FORM:0971168/C3/1> in which X1 and X2, which may be the same or different, are hydrogen, chlorine or bromine, in admixture with unbrominated diisocyanates for example by adding such a mixture to a polyol catalyst system together with antimony oxide and water. The proportion of brominated diisocyanate may be up to 50%, usually 20 to 25% by weight of the unbrominated diisocyanate. The resultant composition, after stirring is poured into a mould and cured, either at room or an elevated temperature.
