  • 5,6,-0-Isoalkylidene ascorbic acid derivatives
    Patent number: 4423236
    Abstract: Novel condensation products between enediol ketolactones such as 5,6-0-isopropylidene ascorbic acid and 2-chloroethyl isocyanates are shown to have potent antitumor activity probably without the release of alkylating agents in vivo. While the structures of the products are not readily elucidated, activity is found to exceed that of BCNU (bis-(2-chloroethyl)-N-nitrosourea) and parallel that of the toxic and highly effective nitrosourea, MeCCNU (1-(4-trans-methylcyclohexyl)-3-(2-chloroethyl)-3-nitrosourea). Preferred compounds are condensation products of ##STR1## wherein R.sub.2 and R.sub.3 are a lower alkyl group containing 1 to 3 carbon atoms or H andhal--CH.sub.2 --CH.sub.2 --N.dbd.C.dbd.O (B)wherein hal is I, Br or Cl.

  • Stepped-down mechanical counting mechanism
    Patent number: 4419571
    Abstract: Stepped-down counting mechanism with number wheels drawn on a locking shaft, with a control disc and with a slotted link. The number wheels and the control disc are moved by a ratchet shaft which is located in the interior of the locking shaft and to which are articulated pawls each acting on one pair of wheels. The switching mode with single or multiple stepping-down can be selected by adjusting the slotted link. The control disc is moved by means of an idle-stroke pawl subjected to the action of the slotted link and, independently thereof, by means of an advancing pawl acting between the control disc and the units wheel.

  • Insertion head for high speed radial lead component sequencing and inserting machine
    Patent number: 4403726
    Abstract: Under direction of a machine controller, an endless chain conveyor is incrementally passed by a plurality of loader heads. The loader heads receive a series of components taped on a reel supplied substrate, sever individual taped components from the supply, and load the individual taped components onto clip carriers of the endless conveyor, on command, in a preferred sequence. The clip carrier mounted components are then indexed past a cutter assembly for trimming the lengths of the leads and removing the substrate, and a positioning disc assembly for positioning the components in the clip carriers before being passed to a rotary transfer assembly. The rotary transfer assembly removes individual components from the conveyor and rotates to an unload position above a linear loader, which laterally transfers the components from the rotary transfer to an insert head assembly.
