Title: System and method for administering radiation
IPC: G21K5/10
Filed: 1974-10-10
Abstract: 1481077 Administering radiation doses VARIAN ASSOCIATES Inc 10 Oct 1974 [12 Oct 1973] 44017/74 Heading G1A A radiation detector is used to monitor the radiation emitted by a source as it moves relative to a target, the source being disabled when, during any increment of its motion, it emits more than a predetermined dose towards the target; emission recommences at the start of the next increment of motion. The source may emit x-rays and move in a circular path around a patient. In Fig. 1 the source is carried on a gantry (not shown) and its output is monitored by an ionization chamber (not shown). The chamber signal is integrated at 20, and because the system is to monitor increments of 2 degrees of source motion, the integrated signal is divided by two at 30. The divided signal is counted at 40 and the total is compared at 60 with a value pre-set at 50. When the pre-set value is reached, comparator 60 operates switch 70 to disable the source, and at the same time resets counter 40. The gantry position is sensed at 80, and a circuit 90 gives a pulse every 2 degrees increment of motion; when such a pulse occurs at the end of an increment it operates switch 70 to restart the source for the next increment. Several safety systems are incorporated. The counter 40 is reset when the source is switched off, so that if for any reason the source emits radiation after switch-off, this will be registered in the counter and will contribute towards the count in the next increment. Also, a counter 100 registers the total radiation emitted when the source is nominally off, and disconnects the power to the source and gantry motor via OR gate 110 if the total is too great. Also provided are a timer 130 which similarly cuts off the power if the gantry moves too slowly, and a counter 140 which cuts off the power if an increment is completed before the source is switched off by comparator 60. A second electrode may be provided in the ionization chamber and connected to its own integrator, divider, counter and comparator to cut off the power via gate 110 in event of failure of the above system, Fig. 4 (not shown). The pre-set switch 50 may also be used to control the gantry motor 180 so that high dose settings result in slow gantry motion; it is also possible to control the source output so that a high dose setting at 50 results in a higher source output. In both cases the object is to make the source radiate during most of each 2 degrees increment.

Title: Methods and arrangements for use in producing continuous patterns
IPC: G03F9/00
Filed: 1971-09-23
Abstract: 1376610 Photographic originals; exposure apparatus MISOMEX AB 23 Sept 1971 [8 Oct 1970] 44412/71 Headings G2A and G2X A method of producing a printing master having first and second members comprises applying a masking sheet 2 to an original 1 bearing a pattern and severing the original and masking sheet together along a non-straight line 8, and using the severed parts to produce the members, the first member 10 having a patterned region and a masking portion which defines a non-straight edge and the second member 11 having a masking portion which defines an opposite edge of the patterned region, both members having registration means e.g. holes for positioning the members for copying. The first member is produced by exposing photosensitive material through a severed portion of the original to give the patterned region separated from a dark masking portion by the non-straight line corresponding to the cutting line 8, see Fig.5. The second member is produced by exposing a photo-sensitive material through a severed portion of the masking sheet to give a transparent region corresponding to the masking sheet separated from a darkened region by a non-straight line corresponding to cutting line 8, see Fig.5. Apparatus for mounting the first and second members on a printing cylinder 14 comprises a frame 18 having location pins 20. The pins engage in the holes in the first member and the frame 18 is rotated from position A to position B to locate the first member or film 10 against the printing cylinder. The lower edge of the film is attached to a screen pattern 16, and the first member is released the pins so that the leading edge of the film is attached to the screen pattern 16. Initially the leading edge with the masking portion is positioned under the light source 17. The cylinder is then rotated and its photo-sensitive surface exposed to the patterned region. When the cylinder has completed a revolution it is stopped and the light source extinguished. The leading edge of member 10 has already been removed and the second member 11 is now positioned in the frame by pins 20 and placed on the cylinder over the trailing patterned edge of member 10, see Fig.5. The light source is again illuminated and the cylinder rotated until the light falls within the masking area of the second member 11. Thus the edges of the exposed pattern exactly coincide so that the cylinder is fully exposed. In an alternative embodiment the frame 18 is replaced by a cylinder with pins for locating the members.

Abstract: 1391892 Pneumatic classifiers MURSKAUSKONE OY 26 Sept 1972 [27 Sept 1971] 44511/72 Headings B2H and B2P A pneumatic classifier for finely divided solids, e.g. cement, talc or kaolin, comprises a housing 1; means 6 to produce a circulation of classifying air within the housing; means 2 for feeding material to be classified to the housing; primary dispersion means 7 located within the housing at a given reference level and using part of the classifying air to effect dispersion of the material therein in a primary dispersion zone 12 in the housing; a horizontal centrifugal classifier 8 located in the housing above said reference level and connected to the primary dispersion zone; secondary dispersion means 18 located within the housing below the said reference level and using the remainder of the classifying air to effect dispersion, in a secondary dispersion zone 21 in the housing, of solids settling out by gravity from the primary dispersion zone, the secondary zone 21 being in communication with the primary zone 12 and with the centrifugal classifier 8; a cyclone 3 connected to the centrifugal classifier 8 to collect the final fine product; and a hopper 4 connected to the secondary dispersion zone 21 to collect the final coarse product. The classifying air consisting of clean air derived from the cyclone 3 via a pipe 5 is circulated through the housing by a blower 6. Part of the air is fed past a control flap 14 through an ejector 7 to which the feed channel 2 is connected so that the solids are dispersed in air in the zone 12. The fraction of solids entrained in the air stream flows via guide plates 13 into the horizontal classifier 8 which is of the cyclone type and from which the fine product is discharged with air through an opening 16 tangentially connected to cyclone 3 while coarse middlings with some fines are returned via a discharge slot 17 to the zone 12. The fraction of solids settling out by gravity from the zone 12 down a funnel 20 are redispersed by the ejector-like means 18 into the zone 21 in which the coarse product settles downwards and is collected in the hopper 4 and the fines are entrained with the air upwards via a channel 22 into the classifier 8. In a modification, Fig. 2 (not shown), the classifier 8 is connected in series with a second classifier of the same type disposed at a higher level. The coarse middlings from the second classifier are directed either to the primary dispersion zone 12 or to a separate collecting hopper and the fines pass with the air into the cyclone 3. Secondary dispersion means in the form of rows of grid bars are disposed downstream of the ejector 7. In Fig. 3, a rotating dispersion drum 29 having circumferentially spaced rods is disposed downstream of ejector 7 and upstream of a stationary dispersion grid 30. The centrifugal classifier 8 consist of a horizontal rotary drum 31 made of spaced parallel rods or, as shown, of triangular shaped ribs.

Abstract: 1,129,847. Control of D.C. motors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 28 Sept., 1967 [7 Oct., 1966], No. 44880/66. Heading H2J. When a triggering signal is applied to a controlled rectifier 2, current is passed from battery 1 to traction motor 3, a controlled rectifier 7 being rendered conductive at the same time so that capacitor 5 is charged through inductance 8. When rectifier 6 conducts, the capacitor 5 renders the rectifier 2 non-conductive, the load current being supplied from the capacitor momentarily. Pulse generators 9-11 are associated with the rectifiers and are connected to a unit 12 to provide triggering signals in the appropriate sequence, the unit 12 comprising a multivibrator which is controlled by a pedal unit 13 to vary the instants at which the rectifiers 2, 6, become conductive in relation to one another. Hence, the mark-space ratio of the motor voltage is varied. When the pedalposition calls for maximum motor voltage, and the operating conditions are otherwise favourable, a unit 15 energizes contactor unit 14 to short-circuit the rectifier 2 which is rendered non-conductive after a delay period. When the mark-space ratio control is to be restored, the rectifier 2 is triggered a short interval before the contactor is opened. A shunt 4 provides a signal to prevent closure of the contactor if this operation would lead to excessive motor current. In addition, the current signal derived from the shunt 4 prevents opening of the contactor if the motor current is greater than that which can be satisfactorily handled by the commutation system associated with the rectifier 2.
