Abstract: The invention relates to a process for the preparation of S(+)-6-methoxy-α-methyl-2-naphthaleneacetic acid by resolution of R,S-6-methoxy-a-methyl-2-naphthalene-acetic acid. According to the invention R,S-6-methoxy-a-methyl-2-naphthalene-acetic acid and R(-)-2-amino-1-butanol are dissolved in water at 40-60 C. Then the solution thus obtained is cooled to 25-35 °C. Subsequently the obtained solution is grafted with a salt of S(+)-6-methoxy-a-methyl-2-naphthalene-acetic acid and R(-)-2-amino-l-butanol, further it is cooled to 5-15 °C. The thereby formed crystals are separated from the solution and washed with water and subsequently hydrolyzed by adding a strong acid, whereby S(+)-6-methoxy-α-methyl-2-naphthalene-acetic acid crystallizes and the obtained crystals are separated from the mother lye and the R(-)-6-methoxy-a-methyl-2-naphthalene-acetic acid present in the crystallization-mother lye is racemized by heating, which racemate solution can be reused as starting material.

Abstract: A package housing (52) for hermetically enclosing an optoelectronic component (56) is formed with a tubular extension (54) which extends outwardly from a wall (52a) of the housing (52) and communicates with the interior of the housing (52) through an opening (52h) formed through the wall (52a). The axis of the extension (54) is self-aligned with a light propagating (transmitting or receiving) portion (56a) of the component (56) as mounted in the housing (52). A piece of optical fiber (60) has an end portion (60c, 60d) which is fittingly retained in the extension (54), and extends substantially from an outer end (54a) of the extension (54) to the light propagating portion (56a) of the component (56). A metal jacket (60b) is stripped from a portion (60c) of the optical fiber (60) which fits in a small diameter outer portion (54b) of the extension (54), whereas a portion (60d) of the optical fiber (60) covered with the jacket (60b) fits in a larger diameter inner portion (54c) of the extension (54). A cap (64) is fixed to the outer end (54a) of the extension (54), and has a central hole (64a) through which the optical fiber (60) extends, to constitute an integral connector (62). The optical fiber (60) is automatically self-aligned with the light propagating portion (56a) of the component (56) by insertion of the end portion (60c, 60d) of the optical fiber (60) into the extension (54).

Abstract: Method for calibration of a particle counter, characterised by the following steps: 
 
  - An aerosol of particles of like particle size is formed in a vector gas stream; 
  - this aerosol is subjected to a bipolar charger (32) comprising an ionising radioactive source; 
  - the aerosol thus charged is passed into a mobility selector (42) which, on the one hand, fixes the charge particles to the electrodes thereby classifying them as a function of the number p of their elementary electrical charges e and allows, on the other hand, the electrically neutral particles to escape; 
  - these neutral particles are collected and they are sent to be calibrated into the particle counter (58) which displays a value N'o; 
  - the values Np and N(p+1) of the number of particles of charges pe and (p+1)e fixed by the selector are calculated and the number No of neutral particles actually sent into the counter is deduced therefrom; 
  - N'o and No are compared.

Abstract: A compound objective lens is composed of a hologram lens for transmitting a part of incident light without any diffraction to form a beam of transmitted light and diffracting a remaining part of the incident light to form a beam of first-order diffracted light, and an objective lens for converging the transmitted light to form a first converging spot on a front surface of a thin type of first information medium and converging the diffracted light to form a second converging spot on a front surface of a thick type of second information medium. Because the hologram lens selectively functions as a concave lens for the diffracted light, a curvature of the transmitted light differs from that of the diffracted light. Therefore, even though the first and second information mediums have different thicknesses, the transmitted light incident on a rear surface of the first information medium is converged on the its front surface, and the diffracted light incident on a rear surface of the second information medium is converged on the its front surface. That is, the compound objective lens has two focal points.

Abstract: A dynamic strobe compensation control for a battery powered barcode printer varies the strobe time for the thermal printhead of the printer during the printing of a line of data to compensate for internal resistance losses in the thermal printhead. The control varies the strobe time based upon the measured voltage of the battery powering the printhead when the battery is not loaded by the thermal printhead and when the battery is load by the thermal printhead. The print quality is thus maintained across the width of a line of print data as well as over multiple lines of print data.

Abstract: An assembly and method provide a continuous supply of packaging film (14) to a form, fill and seal packaging machine (M) with two spindles (20, 24) alternately operating as the active spindle (20) to feed the film (14) from one roll at a time. Opposed pneumatic manifolds (32, 34) are operative to splice the tail-end (E 1 ) of the film (14) from the active roll (12) to the head-end (E 2 ) of the film (18) from the standby roll (16). The opposed manifolds (32, 34) pivot in opposite directions away from the machine (M) to provide easy access for loading. A programmable controller (48) controls the splicing operation. Valves (44) operated by the controller (48) connect a vacuum source (35) to one of the manifolds (32, 34) to hold the head-end (E 2 ) at a splicing station (11) and to the other to maintain tension on the active film (14) after the tail-end (E 1 ) leaves the spindle (20). An end-of-roll detector (45) near the spindle (20) triggers the tensioning function. The width of the manifold (32, 34) is adjustable to accommodate different width film (14). A photocell detector (80, 100) and encoder (85) in the circuit (C) allow tracking of the tail-end (E 1  When it arrives at the splicing station (11), the appropriate control valve (44) rapidly switches to apply an air blast generated by positive pneumatic pressure to blow the tail-end/head-end (E 1 , E 2 ) together so that adhesive tape (T) pre- applied to the head-end (E 1 ) is securely attached to the tail-end (E 1 ) to complete the splicing operation. The programmable controller (48) continues to track the splice through the packaging machine (M) to initiate a dry cycle and removal of the splice section.
