Title: Preparation or ortho-methyl anilines from ortho-amino benzyl sulfoxides
IPC: C07C209/00
Filed: 1983-03-15
Granted: 1985-01-23
Abstract: This invention relates, in one of its aspects, to a process for the preparation of ortho-methyl anilines from ortho-amino benzyl sulfoxides. An ortho-amino benzyl sulfoxide is converted to an ortho-amino benzyl halide by reaction with a nonoxidizing acid halide and is converted to a stable quaternary salt by reaction with a tertiary amine preferably in the presence of an alcohol. The quaternary salt may be cleaved by hydrogenation to form ortho-methyl anilines. Other aspects of the invention relate to novel intermediate quaternary salts and to a process for forming those quaternary salts.

Abstract: A chopper has a housing centered on an axis and having a radially open input and a radially open output spaced angularly therefrom as well as a pair of axially oppositely open intakes, and a cutter drum rotatable in the housing about the axis and having a pair of end plates transverse of the axis and having axially oppositely directed faces confronting the respective intakes and a plurality of blades secured to and between the end plates and having cutting edges defining on rotation of the drum an orbit centered on the axis. Respective pluralities of vanes at the end plates can be secured either to the respective end plates in in-service positions extending generally radially thereon so that rotation of the drum moves the vanes to draw air in the axial intakes and expel it through the radial output or in an out-of-service position in which they do not move appreciable air. The vanes can be secured in the out-of-service position also to the respective end plates but extending generally only angularly. In particular the vanes form a radially closed cylindrical annulus in the out-of-service position. This annulus generally blocks flow from the intake to the output in the out-of-service position. The vanes can also be secured in the out-of service position so as not to rotate with the drum.

Abstract: A machine for manufacturing a unitary glass fibre reinforced body shell includes a carriage which is movable along the mold and a turntable which is mounted on a carriage for rotation about a first axis extending in the direction of longitudinal movement of the carriage. An arm is slidably mounted on the turntable for radial movement and a dispenser is located on the arm for dispensing glass fibre reinforced resin onto the surface of the mold. A guidance system is provided which interconnects the turret and the slidable arm and is operable to cause the arm to reciprocate with respect to the turret in a radial direction to maintain a substantially constant length of trajectory extending between the dispenser and the wall of the mold. A drive system is provided for rotatably driving the turret about the axis. The carriage is normally stored on a mobile end cap which may be moved from one mold to another and serves to close one end of the mold. A canopy is mounted with one end connected to the mold and the other end connected to the dispenser carriage such that as the dispenser carriage moves along the mold, the canopy is deployed to cover the open upper end of the mold to form an enclosed chamber from which fumes may be extracted.

Abstract: The conductive state of a transistor in a semiconductor integrated circuit is determined by irradiating the transistor with a radiation beam and measuring changes in load current, thereby indicating whether the transistor was conducting or non-conducting prior to irradiation. A correlated double sampling method is employed in measuring changes in load current. A load resistor in series with the device under test is capacitively coupled to a differential amplification means including a plurality of differential amplifiers with buffers connected between successive amplifiers. A system clock is stopped at a predetermined time period prior to irradiating the transistor. A bypass switch shunts the load resistor until the clock is stopped.

Abstract: Disclosed is a control device and process for aligning, in the running direction, an endless belt. The device comprises a lifting cylinder with a ram which is retracted or extended as a result of switching signals received from microswitches via a control circuit. The device further includes a pivotal wing which is pivoted by the extending ram in the running direction A of the belt, and a deflecting roller having an axle, the ends of which are mounted in the eyeparts of eyebolts. During pivoting, the wing presses one eyebolt, resting at its bolt end against the front side of the wing, in the running direction A of the belt. The axle, mounted at its axle end, with a certain play in the eyepart of the other positionally fixed eyebolt, is pivoted as a result. As soon as the belt runs out of alignment, that is to say deviates from the running direction A, one of the belt edges actuates the associated microswitch and consequently the lifting cylinder. As a result of the pivoting of the axle of the deflecting roller, the non-aligned running of the belt is constantly counteracted and the belt is deflected counter to the nonaligned direction until it actuates the other microswitch.

Abstract: A composite glass/plastic ophthalmic lens consists of a thin layer (40) of glass, preferably photochromic, adhered to the front of a plastic layer (30), by a highly elastic adhesive (36). The rear surface (42) of the glass (40) has a different radius than the front surface (32) of the plastic (30) so that the space between the lenses forms a tapered gap which is filled by the elastic adhesive. The edge thickness of the elastic adhesive is sufficient to insure that the increase in diameter of the plastic layer with respect to the diameter of the glass layer due to differences in the thermal expansion characteristic of the glass and the plastic will not damage the lens even over a temperature range > 300°F (170°C).The glass layer (40) is shaped to have a power which compensates for differences in the index of refraction of the glass (40), adhesive (36) and plastic layer (30), and which compensates for the optical powers produced by the tapered adhesive layer, so that the composite lens can be finished to prescription as though it were an all-plastic lens.

Abstract: A missing pulse detector in which the absence of a pulse in a variable frequency periodic pulse train (30) is detected and distinguished from a reduction in the pulse repetition rate. Between successive pulse train pulses a first counter (46 or 70) counts clock pulses at a first rate (3f1) and develops a maximum count related to the time duration between successive pulse train pulses. This maximum count is effectively maintained by a latch circuit (47 or 71) during the next time duration between successive pulse train pulses and is effectively compared with the count of a second pulse counter (49 or 71) which counts clock pulses during successive pulse train pulses at a second rate (2f1) normally less than the first incrementing rate (3f1). When the count of the second counter (49 or 71) exceeds by a predetermined amount the effectively latched count of the first counter (46 or 70), this indicates the occurence of longer time duration and a count comparator (48 or 71) and logic circuit (55) provides an arming output signal (64). In response to the arming output signal, the incrementing rate of the second pulse counter (49 or 71) is increased to a third rate (4f1) which exceeds the first incrementing rate (3f1). If after the arming output signal (64) the maximum count of the second counter (49 or 71) between successive pulse train pulses is less than the maximum count achieved by the first counter (46) between preceding succesive pulse train pulses, then a missing pulse detection signal (66) is produced.
