Title: Improvements in the manufacture of methyl methacrylate
IPC: C07C67/327
Filed: 1958-12-23
Abstract: Methyl methacrylate is prepared by acid hydrolysing acetone cyanohydrin to methacrylamide, esterifying the amide with methanol in the presence of water while distilling off and condensing the resulting ester in the form of its methanol/water azeotrope, mixing the condensed azeotrope with a quantity of water having a weight less than that of the condensate, at a temperature not exceeding 20 DEG C., and thereafter decanting in order to obtain an aqueous phase containing the major portion of the methanol and an organic phase containing the major portion of the ester and recycling the aqueous phase directly to the second p  stage (esterification) in a subsequent operation of the synthesis.  The azeotrope is preferably treated at below 10 DEG C. and with 10-50% by weight of water. Suitable apparatus for this stage is described.  In examples, acetone cyanohydrin is reacted with sulphuric acid at 90 DEG -100 DEG C., the mixture is then refluxed with methanol and water while removing an ester-methanol-water azeotrope; the condensed azeotrope is mixed with 15-25% water at -10 DEG  to 20 DEG C., and the resulting aqueous alcohol phase is removed by decantation and recycled to the esterification stage in a subsequent operation of the synthesis. Example 6 illustrates a continuous synthesis.

Filed: 1976-10-13
Abstract: 1535342 Electronic timepieces DAINI SEIKOSHA KK 13 Oct 1976 [15 Oct 1975] 42537/76 Heading G3T An electronic timepiece with digital display, e.g. liquid crystals, is arranged to display time of day in hours, minutes and seconds and, on the same display devices, chronograph time in either hours minutes and seconds or tenths and hundredths of seconds in dependence upon the state of a manual selector switch means. For chronograph operation, a switch SW1 Fig. 1 is closed, and transmission gates 13-18 are controlled to select the contents of counters 3 and 4 or 5 and 6 for display. With a switch SW2 open, the count in seconds counters 5, 6 is applied via transmission gates 14, 16, 18 to a decoder-driver 19 which causes the seconds and tens of seconds indication. In addition, a driver circuit 26 causes the display of the count in minutes and hours counters 7-10. In the driver circuit 26, AND gates 24 receive a 32Hz pulse train derived from oscilator circuit_1, and AND gates 23 receive the pulse train (i.e. 32 Hz) via an inverter and transmission gate 21. The common electrode of the display receives the 32 Hz pulse signal. If an output of decoder 22 is logic "I", a respective AND gate 23 is open to pass the 32 Hz pulses via an OR gate 25 to an appropriate display segment so that a potential difference exists between that segment and the common electrode. If switch SW2 is closed, with switch SW1 still closed, the transmission gates 14, 16, 18 will be blocked and transmission gates 13, 15, 17 opened to pass the output of the 1/100 seconds and 1/10 seconds counters 3, 4 to the decoder-driver 19 for display on the same devices previously used for seconds display. In addition, gate 21 is blocked and gate 20 is opened to pass the 32 Hz pulses to AND gates 23 instead of the 32 Hz pulses, the AND gates 24 receiving the 32 Hz pulses as before. Therefore the OR gates 25 will pass the 32 Hz pulses to the display segments whether the decoder 22 outputs are high or low. Consequently there will be no potential difference between the common electrode and segments and hence no display of hours and minutes.

Abstract: 1359723 Cutting apparatus GERBER GARMENT TECHNOLOGY Inc 15 Sept 1971 [1 March 1971] 42937/71 Heading B4B An apparatus for cutting sheet material, e.g. fabric material, comprises a cutting blade 38 adapted to be reciprocated by a mechanism 36 which is movable over a penetrable surface 28 for supporting the material, the blade having a downwardly facing cutting edge 40 and means for simultaneously reciprocating the blade and moving it forwardly along a desired line of cut, such movement taking place when the blade is clear of the material. The mechanism 36 for reciprocating the blade is mounted on a carriage 16 which is movable transversely of the material on a carriage 21 movable longitudinally of the material, the driving motors therefor being under the control of a computer. During operation, the blade is raised above the surface of the material as shown in Fig. 4, by an amount such that the horizontal distance through which the blade moves is substantially larger than the horizontal distance moved by the blade while in the material. This effect enables the portion 52, Fig. 4, of the material to be cut with a chopping action, the portion 54 being cut by a forward facing cutting edge 38 when the blade is in the material. In a modification, the cutting edge 40 may be inclined such that the cutting point 42, Fig. 4, is formed at the rear edge of the blade. In a further modification, Fig. 8 (not shown), the drive to carriage 21 is stopped during the time the blade is within the material so that the cutting is carried out entirely by a chopping action with the cutting edge 40. The mechanism for reciprocating the blade may be arranged to give the blade an additional orbital motion (Fig. 10, not shown).
