摘要:
A camera system for the simultaneous and substantially exact capturing of images of a subject on separate image reproduction mediums wherein an optical member is interposed between a lens group and a pair of separate, discrete image receiving mediums. One of the mediums is a photographic film and the other is a viewing screen for personal viewing or, alternatively, an electronic system for electronic signal generation, electronic viewing and electronic capture of the image. The optical member allows light rays emanating from the object to pass therethrough to impinge upon one of the mediums while simultaneously reflecting light rays to the second medium. This system allows for the simultaneous transfer and reproduction of the object image onto more than one medium without degradation of the image or depth of field. The system accomplishes the multiple image transfer through a stationary device, thereby eliminating the necessity of moving parts. The system also eliminates problems resulting from refractions of light normally accompanying light ray direction control devices.

A method is provided for treating a drug-dependent individual so as to effect withdrawal from a drug of abuse, e.g., an opiate such as heroin or oxycodone, a stimulant such as cocaine, or alcohol. The method involves substitution therapy wherein a substantially nonaddicting normorphine or norcodeine derivative is substituted for the drug of abuse. The active agent has the structure of formula (I) wherein: R is H, alkyl, or acyl; X is CH(OR′) or C═O, wherein R′ is H or acyl; α is an optional double bond, with the proviso that when α is present, then X is necessarily CH(OH), or an acid addition salt thereof, wherein preferred such agents are in a stereoisomerically pure form that corresponds to that of N-[(1R)-1-cyclopropylethyl]-normorphine (1) which melts at approximately 188° C.-189° C.

摘要:
Stereoisomerically pure forms of normorphine analogs which have superior analgesic and nonaddicting qualities are described. In addition, a method of separating diastereomeric forms of N-sec-alkyl-substituted analogs utilizes the hydrocarbyl(1-8C) diesters of the normorphine derivatives. A new method for preparing the N-methylalkylmethyl derivatives of normorphine and norcodeine and their conventional analogs is also disclosed. This method employs the corresponding methyl alkyl ketones and a reducing agent.
摘要:
Novel N-sec-alkyl derivatives of norcodeine and normorphine wherein the sec-alkyl group contains either four or five carbon atoms. Specifically included are those derivatives of norcodeine and normorphine wherein the sec-alkyl group is 2-butyl, 3-pentyl, .alpha.-methylallyl and .alpha.-methylcyclopropylmethyl. The normorphine derivatives have strong agonist potency combined with strong antagonist qualities and indicated low addiction potential. The norcodeine analogs are useful as intermediates in preparing the corresponding normorphine compounds.

摘要:
A light beam scanning device and method comprises a first input source for providing a scanning light beam and a flat stationary scanning surface to be scanned by the beam. An f sine theta lens system focuses the light beam onto the flat stationary scanning surface. A galvanometer mirror provides for repetitively scanning the light beam across the flat stationary scanning surface in a first fast scan direction while a pivoting mirror provides for receiving the light beam and scanning it onto the galvanometer mirror in a second slow scan direction perpendicular to the first direction. The cooperative operation of the galvanometer mirror and the pivoting mirror raster scan the light beam onto the flat stationary scanning surface. A second light source generates a reference light beam which is directed onto a rear mirror surface of the galvanometer mirror from which it is directed to a nonlinear grating having line spacing proportional to 1/(sine theta) for defining the position of the scanning beam in the first direction. The grating is scanned by the reference beam as is reflected from the galvanometer mirror and passes from the grating to a detector for generating a control signal representative of the position of the scanning light beam in the first direction. The grating may be reciprocally moved relative to the galvanometer mirror to compensate for distortion of the image scanned in the flat stationary scanning surface.
