Abstract: A training device comprising a target member, having a target face, a target arm and target support facilitates a training regiment for soccer, baseball, football and hockey players. The target support is coupled to a goal post or cross-bar of a goal. The target member is adjustably joined to the target support such that the target member and corresponding target face may be positioned in a plurality of locations without uncoupling the target support. The target face can be positioned in a plurality of positions throughout a vertical plane and may also be adjusted in a direction parallel to the target arm. The adjustability of the target face provides a versatile training device which can be arranged in numerous configurations to maintain fresh training regiments. In practice, multiple training devices maximize the effectiveness of the training. Other features include target face illumination means, counters and speakers for transmitting audio outputs.

Abstract: Laser capture microdissection occurs where the transfer polymer film is placed on a substrate overlying visualized and selected cellular material from a sample for extraction. The transfer polymer film is focally activated (melted) with a pulse brief enough to allow the melted volume to be confined to that polymer directly irradiated. This invention uses brief pulses to reduce the thermal diffusion into surrounding non-irradiated polymer, preventing it from being heated hot enough to melt while providing sufficient heat by direct absorption in the small focal volume directly irradiated by the focused laser beam. This method can be used both in previously disclosed contact LCM, non contact LCM, using either condenser-side (or beam passes through polymer before tissue) or epi-irradiation (or laser passes through tissue before polymer). It can be used in configuration in which laser passes through tissue before polymer with and without an additional rigid substrate.

Abstract: A method of microdissection which involves forming an image field of cells of the tissue sample utilizing a microscope, identifying at least one zone of cells of interest from the image field of cells which at least one zone of cells of interest includes different types of cells than adjacent zones of cells, and extracting the at least one zone of cells of interest from the tissue sample. The extraction is achieved by contacting the tissue sample with a transfer surface that can be selectively activated so that regions thereof adhere to the zone of cells of interest to be extracted. The transfer surface includes a selectively activatable adhesive layer which provides, for example, chemical or electrostatic adherence to the selected regions of the tissue sample. After the transfer surface is activated, the transfer surface and tissue sample are separated.

Abstract: A tissue sample is conventionally visualized in a microscope. A selectively activated convex surface is provided, preferably at the distal end of a rod. This selectively activated convex surface when activated, typically with a laser through an optic light path in the microscope, provides the activated region with adhesive properties. At least one portion of the tissue sample which is to be extracted is identified. This identified portion is contacted with a portion of the selectively activated convex surface on the end of the rod. When the convex surface is activated, typically by exposure to laser light in the footprint of the desired sample, an adhesive transfer surface on the selectively activated convex surface is provided which adheres to the desired cells in the footprint of the desired sample. Thereafter, the adhesive transfer surface is separated from the remainder of the tissue sample while maintaining adhesion with the desired cells. Thus the desired portion of the tissue sample is extracted.

Abstract: An apparatus and process for the micro juxtaposition is set forth where a selectively activatable surface is maintained spaced apart from the tissue sample and juxtaposed to the tissue sample by activation. In the typical case, activation occurs by laser radiation with the material of the activatable surface thermally expanding and bringing about the desired micro juxtaposition. The disclosed micro juxtapositioning can cause locally and microscopically pressure on tissue sample, insertion to the tissue sample, or contact of an activated or prepared surface to the tissue sample.

Abstract: A method and apparatus of gathering by LCM identified cellular material from randorn locations on a tissue sample to designated locations on a transporting substrate enables convenient further processing. A transporting substrate has an identified mapped location for receiving identified cellular material. At least a segment of a selectively activatable coating is placed on the side of the transporting substrate in apposition to the tissue sample at the mapped location. The transporting substrate and sample are relatively moved to place the selectively activated coating at the mapped location in apposition to identified cellular material of the tissue sample which is to be extracted. Thereafter, the selectively activatable coating is activated and impressed or impressed and activated to form an adhesive region on the transporting substrate for adhering to the identified cellular material.

Abstract: Laser capture microdissection occurs where the transfer polymer film is placed on a substrate overlying visualized and selected cellular material from a sample for extraction. The transfer polymer film is focally activated (melted) with a pulse brief enough to allow the melted volume to be confined to that polymer directly irradiated. This invention uses brief pulses to reduce the thermal diffusion into surrounding non-irradiated polymer, preventing it from being heated hot enough to melt while providing sufficient heat by direct absorption in the small focal volume directly irradiated by the focused laser beam. This method can be used both in previously disclosed contact LCM, non contact LCM, using either condenser-side (or beam passes through polymer before tissue) or epi-irradiation (or laser passes through tissue before polymer). It can be used in configuration in which laser passes through tissue before polymer with and without an additional rigid substrate.

Abstract: The invention is a process to manufacture the intermediate secondary amine N-ethyl-2-chloro-6-fluoro-benzylamine, and then the process of reacting this intermediate to manufacture the herbicide flumetralin. Equimolar quantities of monoethylamine, sodium hydroxide, and 2-chloro-6-fluorobenzyl chloride are reacted at a temperature between about 70.degree. C. and about 100.degree.
