Abstract: N-[N-(Tetrahydropyrido[2,3-d]pyrimidinylmethyl)aminomethylbenzoyl]glutamic acid derivatives of formula 
 are anti-neoplastic agents with an effect on one or more enzymes which utilize metabolic derivatives of folic acid. The compounds can be prepared by allowing a protected aminomethylbenzoylglutamic acid derivative to react with 2-amino-4-hydroxy-6-formylpyrido[2,3-d]pyrimidine, reducing the intermediate Schiff base, and subjecting the intermediate to catalytic hydrogenation. A typical embodiment is (S,S) N-[N-(2-amino-4-hydroxy-5,6,7,8-tetrahydropyrido-[2,3-d]pyrimidin-6-ylmethyl)-4-aminomethylbenzoyl]-glutamic acid.

Abstract: Tubular (22) parts are delivered to a rotary positioner (46), or preferably in successive pairs to separate rotary positioners, where they are held for laser machining: in the preferred arrangement, the pairs of parts are machined in parallel by twin laser cutting beams directed thereat by a commonly mounted pair of focussing heads (42). The rotary positioners (46) are commonly rotated through a programmed series of angular motions in conjunction with a programmed series of joint X and Y axes linear motions of the focusing heads to scan the cutting beam over the surfaces of the parts and thus machine identical feature cuts in the sidewall of each part. Machining is performed under an inert gas atmosphere, and cuttings are vacuumed from the machining sites through apertured mandrels (86) inserted into the part bores.

Abstract: A device is described for separating the fillets from fish rumps, in which cutting tools (2, 3 and 4), in each case consisting of pairs of circular blades, are used for cutting free the abdominal fins, the dorsal fins and the ribs or lateral extensions of the spines. The last-mentioned cutting tool (4) has in this case a double function, which is based on the fact that each cutting blade (7) of this tool is allocated guide element (35) bearing, in the rest position, with its guide surface (37) on the inner surface of the circular blade (7). These are provided with guide edges (36) for supporting the vertebrae of the spinal column and can be displaced in the cutting planes of the circular blades (7) and, in the displaced position, can be guided in such a position in which there is opened out, in each case between the inner surface of the circular blades (7) and the guide surface (37), a gap for the passage of the ribs or lateral extensions of the spines. The guide elements (35) are displaced by the action of conveyor discs (43) which support the vertebrae of the spinal column on the opposite side. …<IMAGE>…

Abstract: An image-forming method including the steps of forming a thin layer of a photosensitive toner charged to have a given polarity on a conductive drum (43), exposing the thin layer to light according to image information, and transferring a part of the photosensitive toner onto a transfer material (63). The transferring step includes contacting the transfer material with the thin layer after the exposing step as applying a pressure to the transfer material, and irradiating a corona ion from a back side of the transfer material to the thin layer by using a corona charger (45). Thus, the transfer material is maintained in pressure contact with the thin layer of the toner during the transferring step, thereby improving a transfer efficiency of the toner to the transfer material to obtain a satisfactory image having a high density and no void.

Abstract: An energy subtraction processing method for radiation images comprises the steps of irradiating radiation, which has a predetermined energy range, to an object, and irradiating the radiation, which has passed through the object, to a recording medium capable of recording a plurality of radiation images during its exposure to radiation with different energy distributions. A plurality of radiation images of the object are thereby recorded on the recording medium. From the recording medium on which the radiation images have been recorded, a plurality of image signals are obtained which represent the radiation images of the object. An MTF correcting process is carried out on the image signals such that differences between MTF's of the radiation images of the object may be eliminated. Subtracting operations are then carried out on image signals, which are obtained from the MTF correcting process.

Abstract: An amplification circuit comprising a differential amplifier is disclosed. An npn transistor (20) composing the differential amplifier having its base provided with negative feed back, the base potential is brought to a constant potential, i.e. a virtual ground potential. The voltage between the base and emitter of the transistor (20) is thus kept constant, and the internal resistance of the emitter does not change in accordance with the change of the emitter current. As a result, since the transistor (20) responds only to an input signal current converted by a resistor (23) and operates, the linearity between the input and the output of the differential amplifier is improved.

Abstract: A computer implemented system analyzes shop dispatch rules using current status and a simulation system for the shop floor to establish the dispatch rules to be used to mini­mize tardiness. When re-work orders are introduced into the system, the shop floor orders have to compete for the same resources, and so the sequence for dispatch may have to be modified to meet the new demands on the shop floor resources. The system provides the capability such that minimum impact is felt on existing orders while maintain­ing management objectives. The system provides feedback to the user and the up-stream planning system if major changes need to be made on the shop floor schedules. The system develops revised dispatch rules to be followed and the associated sequence of operations to be followed after the introduction of re-work shop orders. The approach taken is repeated interactively and forms what may be characterized as a "bottoms up" approach to analyze the floor schedule taking into consideration the re-work orders and feeds the information to the original planning process. The system automatically creates a list of alternative processes that any production order can follow and establishes optimum process flows in the event of introduction of re-work shop orders. The system automati­cally passes the information to the planning system which then re-calculates the revised order release sequence for the remaining orders in the release process.
