Abstract: A method and apparatus for computerized axial tomography (CAT) image reconstruction applicable to X-ray scanning of the human body. Successive series of calculations determine the values of a characteristic in defined eegmented areas of an examination plane. A reduction in the time and equipment requirements for reconstruction calculations may thereby be effected. 
     Images representative of the difference between the value of the characteristic at a reconstruction point and the average value of the characteristic in adjacent regions (Δµ) may be calculated and displayed from measurements taken within a localized contiguous region of the examination plane. Radiation dose to patients and computation time in X-ray computerized axial tomography scanning systems is thus reduced. Differential displays of the type described may be adjusted to image boundaries, in which case they do not suffer from gray scale resolution problems which are typical of prior art displays. 
     Image artifacts attributable to interpolation errors may be reduced with negligable effect on resolution by incorporating a weighting function, preferentially a Gaussian function, in the image reconstruction.

Abstract: The invention relates to a subscriber station with a base set (1) and a cordless handset (2), between which a transmission occurs by means of short PPM or PCM RZ pulses in a band of infrared radiation, possibly via a relay station (17) attached, for example, to a room ceiling. For this purpose, the invention provides an infrared pulse transmitter (4, 7) and infrared pulse receiver (5, 8). For transmission by means of PPM, further AF/PPM and PPM/AF converters are provided (20, 25; 29, 26) and for transmission by means of PCM a PCM NRZ/PCM RZ converter (20'), a PCM RZ/AF converter (26'), an AF/PCM RZ converter (25') and a PCM RZ/PCM NRZ converter (19') are provided. In this connection, NRZ means non return to zero and RZ means return to zero. Due to the use of a discrete-value type of modulation and short pulses, only a low transmitting power is required (Figures 1 and 2). Dialling and special characters are transmitted in accordance with the dual-turn multi-frequency method (DTMF). Ringing signals are transmitted by changing the pulse frequency transmitted between handset (2) and base set (1). The connection is continuously monitored by a monitoring circuit (UE). A diversity circuit of IR photodiodes with subsequent regulated receive amplifier (EV) is used as IR pulse receiver (5, 8). <IMAGE>

Abstract: in a static inverter for providing a low-frequency output (e.g. 60Hz) from a d.c. supply (Q), the passage of low-frequency currents through the inverter transformer (P) is avoided by producing a train of high-frequency pulses (e.g. 40kHz) which represent, for example by their pulse widths (4), the successive instantaneous amplitudes of the required low-frequency voltage. These pulses cause a train of corresponding pulses (7) to be produced at the secondary of the transformer, and this train is filtered (H) to produce a unidirectional voltage (9) having the desired instantaneous amplitudes. This voltage is fed to a transistor switching bridge (1) which changes the unidirectional voltage into an alternating voltage (12) having the required low-frequency. Means (N, E, L, M) is preferably provided to allow regeneration of power from the load back into the d.c. supply (Q).

Abstract: Systeme de commande logique numerique pour un moteur a courant continu alimente par batterie ayant un induit (20) et un champ excite separement (21). La vitesse requise par l'operateur et la vitesse reelle du moteur sont comparees continuellement pour determiner si le moteur doit fonctionner en mode puissance ou mode freinage, et egalement le degre d'acceleration ou de deceleration du moteur par rapport a la vitesse demandee. Dans le mode puissance: le courant de champ est commande comme une fonction inverse des vitesses demandee et reelle sur toute la gamme de vitesse; aux petites vitesses, le courant de l'induit est commande comme une fonction de la vitesse demandee; aux hautes vitesses, l'induit (20) est connecte continuellement a la batterie (22), jusqu'a ce que la limite superieure de haute vitesse soit atteinte lorsqu'on permet ou empeche le courant de l'induit de passer de maniere intermittente pour maintenir la vitesse a une telle limite. Dans le mode freinage: a vitesses elevees, l'induit (20) est connecte a la batterie (22) pour le freinage par recuperation; aux petites vitesses, l'induit (20) est court-circuite pour un freinage resistant; la direction du courant de champ est inchangee et son niveau est commande pour maintenir le courant de frein de l'induit a une limite maximum possible. Lors du branchement, le moteur fonctionne dans le mode freinage et le fonctionnement des contacts d'inversion de champ (40, 41, 44, 45) est retarde jusqu'a ce que le courant de champ tombe a une valeur basse. Dans le circuit a hacheur SCR unique, la conduction du SCR principal (SCRMA) est commandee comme une fonction a la fois de la frequence d'impulsion et de la longueur d'impulsion d'un multivibrateur monostable (226).

Abstract: An injection-molding apparatus has a nozzle extending along an axis and formed with an axially forwardly opening outlet, an annular port fixed immediately axially behind or upstream of the outlet, and a central axially forwardly opening port axially fixed behind the annular outlet. Respective plastifiers for feeding respective plastified synthetic resins, normally thermoplastics, are connected to the respective ports. An axially displaceable valve body in the nozzle is displaceable from a fully forward position blocking both of the ports, through a partially back position blocking only the central port, to a fully back position clear of both of the ports. Thus in the fully forward position no resin can enter the nozzle, in the partially back position resin can enter the nozzle only from the annular port, and in the fully back position resins can enter the nozzle through both of the ports.
