Abstract: Un systeme a deux etages (u) ameliore l'uniformite d'image d'une camera a scintillation nucleaire. Le systeme compense l'imprecision de l'indication donnee par la camera a la fois pour la densite des comptages locales de radiation et pour le niveau d'energie. Un premier etage (30, 32) situe et emmagasine une representation des cretes respectives de la distribution en hauteur des impulsions d'energie detectees pour chacune des regions du champ de vision de la camera. Cette representation est utilisee pour realigner successivement pour chaque comptage la fenetre d'energie respective pour chaque comptage la fenetre d'energie en hauteur de l'impulsion, pour aligner la fenetre sur la crete d'energie respective pour chaque comptage en fonction de la situation de celui-ci dans le champ. Un second etage de correction de flots (40, 42, 44) produit en emmagasine un profil de variations locales de la densite de comptages d'images indiques par la camera en reponse a un champ de flots de radiations uniformes. L'information emmagasinee est utilisee pour calculer les facteurs de correction de densite de comptage locaux pour les differentes regions du champ de la camera. Les facteurs de co-actions sont appliques pour commander le taux de comptages de radiation correspondant a chacune des regions prises en image.

Abstract: A light source includes a high pressure discharge lamp (26) and incandescent filaments (24 and 30) which provide illumination during the warm-up and hot restart periods associated with the discharge lamp (26). A current regulator (22), which provides dc power to the discharge lamp (26), draws sufficient current through one filament (24) to energize the filament (24) only during discharge lamp (26) warm-up. A second filament (30) provides illumination during the period after the occurrence of a momentary power failure or power transient which is required by the discharge lamp (26) to cool down to its maximum starting temperature. A bimetal switch (32) permits current flow through the second filament (30) when the discharge lamp (26) is above the maximum starting temperature. An electronic switch (34) permits current flow through the second filament (30) when a current sensing resistor (28) senses a lack of current through the discharge lamp (26).

Abstract: A method and an apparatus is decribed for sensing the extent of actual wear of a grinding wheel (22) at an area where the wear will be the greatest during the grinding of a workpiece (30). The grinding wheel (22) is dressed by removing material from the grinding wheel (22) to an extent which is a function of the extent of sensed wear at the location where the wear is the greatest. The apparatus includes a probe member (54) which is movable toward the circular working surface or side (26) of the grinding wheel (22) from a retracted position and a detector assembly (70) which detects when the probe member (54) initially engages the circular side (26) of the grinding wheel (22). In some embodiments of the invention, the probe member (54) is moved toward the grinding wheel (22) in incremental steps with sufficient time between the steps to enable the grinding wheel (22) to rotate through slightly more than one complete revolution. In one embodiment of the invention the detector assembly (70) includes a mass which is connected with a probe member (54). Upon initial engagement of the probe member (54) with the circular side (26) of the grinding wheel (22), relative acceleration occurs between the mass and probe member (54). In another embodiment of the invention the detector assembly (70) includes a load cell which detects the occurrence of deflection upon initial engagement of the probe member (54) with the grinding wheel (22). In still another embodiment of the invention, the probe member (54) is moved with a wheel dressing tool (42) to detect when a wheel dressing operation has been completed. After a wheel dressing operations has been completed the rotational speed of the grinding wheel (22) is increased to maintain a desired surface speed even though the diameter of the grinding wheel (22) has decreased.

Abstract: A drip irrigation system provides drip action of water flowing under pressure in an irrigation supply pipe (12). A drip emitter unit (10) secured to the exterior of the supply pipe (12) receives water from the supply pipe (12), passes the water through a labyrinthine channel (27) formed internally between the drip emitter (10) and the exterior wall of the supply pipe (12), and discharges the water from the internal channel at a greatly reduced pressure drop so that water drips at a slow rate. In one embodiment, the drip emitter (10) is bonded to the exterior wall of the irrigation supply pipe (12) by magnetic induction heating techniques. A region of fusible bonding material (38) is disposed around the outside boundary of the labyrinthine channel (27). The emitter (10) is placed over the supply pipe (12) so the fusible bonding material (38) overlies the exterior wall of the pipe (12), and the bonding material (38) is fused by magnetic induction heating techniques to weld the inside of the emitter (10), around the exterior of the labyrinthine channel (27), to the exterior wall of the pipe (12).
