Abstract: 1,060,639. Disc brakes. T. CAMPAGNOLO. Dec. 6, 1963 [Dec. 7, 1962], No. 48372/63. Heading F2E. A disc brake assembly comprises a caliper housing made up of two parts 1, 2 interconnected by bolts 3, the part 1 being provided with one pair of friction pads 5 adapted to be actuated by opposed hydraulic piston-andcylinder mechanisms 9, 1 (Fig. 2, not shown), and the other part 2 being provided with a second pair of opposed friction pads 6 adapted to be actuated by mechanical means. Operation of the mechanically applied friction pads 6 is effected by operation of a lever or pedal which exerts a pull on a pin 31 of a forked lever 21 to cause rotation of the latter and thereby rotate two integral,cam-plates 23 so that balls operating in inclined conical ramps are actuated to move plates 20 along the axes of cylindrical seats in the caliper body 2 and, as the plates 20 are shifted, sleeves 18 and pins 17 are carried along to urge the friction pads 6 against the brake disc. On release of the mechanical control, springs 19, which have been compressed during the braking action, return the camplates 20 through the pins 17 and sleeves 18 to cause the balls 24 to descend the conical ramps until they are brought into a central position and the friction pads 6 are thereby moved away from the disc 4 under the influence of the rotary movement of the latter and through the restoring action of flexible rings (not shown) which are provided in backing plates 15. Adjustment for wear of the friction pads 6 can be achieved by adjustment of the screwed pins 17 in their sleeves 18 and locking these two elements to one another by means of lock-nuts 30. The hydraulically operated friction pads 5 are carried by plates 7 which are mounted to rock on central projections 8 of pistons 9 formed with an annular cavity 10 and sliding in opposed cylinders 11 of the caliper part 1 (Fig. 2, not shown).

Title: Reducing the Corrosion of Graphite in Nuclear Reactors
Inventor: POINTUD MARIE-LOUISE
IPC: G21C1/12
Filed: 1967-10-27
Abstract: 1,166,001. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 27 Oct., 1967 [7 Nov., 1966], No. 48978/67. Heading G6C. A method for reducing the graphite corrosion in a graphite - moderated, CO 2 -cooled nuclear reactor is characterized in that a flow of coolant containing a gaseous corrosion inhibitor is forcibly circulated inside the pores of the graphite. Suitable inhibitors include CO, H 2 , light saturated hydrocarbons (e.g. methane) and oxygenized hydrocarbon derivatives (e.g. acetone). In one embodiment, a reactor core is formed of graphite blocks 6 assembled in columns connected by keys and separated by clearances. Each block 6 has a vertical channel 4 opening at its lower end in a debris collector 10 having openings 12 for the CO 2  which flows along the channel as indicated by the arrows f. Each channel 4 locates a set of fuel cartridges 16 each having a graphite sleeve 18 and a fuel element 20, the latter consisting of a tubular slug of slightly alloyed uranium with a protective coating on its inner and outer surfaces, being retained in the sleeve 18 by an annular saddle 22 connected to the sleeve by retaining wires. Partitions 24 centre the fuel element 20 in the sleeve 18. The local head loss #P due to the collector 10 is so selected as to avoid excessive aerodynamic forces on fuel elements during the unloading of a channel. By-pass ducts 26 parallel to the channels 4 are formed between adjacent blocks 6 and open into the coolant collecting space downstream the core through nozzles 28 providing a head loss #P considerably higher than #P. At any predetermined level, a pressure difference exists between the channels 4 and the ducts 26 resulting in a small flow of CO 2  loaded with inhibitor through the pores of the graphite blocks, as shown by arrows f<SP>1</SP>. This flow tends to maintain the inhibitor content of the CO 2  in the graphite pores at a value near that which prevails in the remainder of the coolant circuit. Protection of the sleeves 18 against corrosion is not always necessary since they stay in the reactor for a relatively short time. If, however, it is preferred to force a coolant flow radially through the sleeves, an annular space between the sleeves and the channel wall is connected to the space downstream the core by restricted passages 34 providing a head loss #P<SP>1</SP> whose value is between #P and #P. The invention may be used in reactors other than those employing non-enriched uranium metal as fuel, in particular it may be used in reactors in which the fuel elements comprise bundles of fuel pins employing enriched UO 2  as fuel.

Title: Optical tracking apparatus
IPC: G01S3/78
Filed: 1977-12-01
Abstract: An image of the target object is produced, by means of an objective lens (1), in the visible light band in a first imaging plane (F1). The same lens produces the image of a beam source, for example a laser diode, which is arranged on the target object, in a second, advanced imaging plane (F2). The radiation from said beam source is separated from the rest of the beam path by means of a prism (3) while the visible light is passed to an eyepiece (4) through which the operator aims at the target object with the aid of an aiming symbol which is arranged in the first imaging plane (F1). The separated radiation, which has passed through a measurement mask arranged in the second imaging plane (F2), is supplied to a photodetector (7). The evaluation of the signals of the photodetector allows the respective angular deviation of the target object from the line of sight to be determined. The unit allows the target object to be aimed at and allows its angular deviation with respect to the line of sight to be determined by means of a single optical system, as a result of which adjustment devices are rendered superfluous. <IMAGE>
