Title: Improvements in or relating to nuclear fuel elements
IPC: G21C21/02
Filed: 1962-06-05
Abstract: 971,930. Moulding refractory materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 5, 1962 [June 12, 1961], No. 21682/62. Heading B5A. [Also in Division G6] Nuclear fuel pellets are made by mixing a powdered refractory fuel material, e.g. uranium oxide, carbide, nitride or silicide, with a suitable binder and lubricant to form a paste which is granulated, the grains being dried and screened and then compressed in a press provided with two monobloc stamps of truncated conical shape to form male and/or female end parts on the pellets. Alternatively, as shown in Fig. 8, the press may have one monobloc and one multiple stamp, the latter comprising two coaxial cylindrical stamps 18, 19 slidable in relation to one another and shaped to form a male end part. The monobloc stamp 17 forms a female end part. The head 21 of the inner stamp 18 is attached to a plate 23 by means of a screw 24 whereas the head 22 of the outer stamp 19 rests on three equi-spaced stops 25 spaced from one another at angles of 120 degrees around the head 21, a rubber ring 20 being located between the heads 21, 22. Compression of the granules 15 is effected by lowering the stamps 18, 19, the outer stamp 19 stopping on touching the granular mass while the inner stamp 18 slides within the stamp 19 until the heads 21, 22 abut, whence the stamps 18, 19 apply equal pressure to the granules 15. The compression should be bilateral if the pellet is to have equal densities in two cross-sections symmetrical in relation to the median plane of the pellet and this may be achieved by mounting the press block on springs, this causing the stamp 17 to have a relative upward movement with respect to the granular mass. A press having one monobloc and one multiple stamp as described above provides for the manufacture of larger pellets than a press having two monobloc stamps. After compression is applied, the pellet obtained is ejected by returning the stamps 18, 19 to their initial high position and raising the stamp 17.

Title: Test equipment for a radar set
IPC: G01S7/40
Filed: 1957-07-12
Abstract: 808,891. Testing radar systems. SPERRY RAND CORPORATION. July 12, 1957 [July 12, 1956], No. 22148/57. Class 40 (7). Relates to test equipment for radar set in which an echo box.21 is associated with the feed to the radar antenna so as to cause the production of an exponentially decaying echo pulse which may be limited in the receiver video amplifier 24 to provide a pulse B the width of which is a measure of the radar set performance in respect of receiver gain and alignment and transmitter power output. According to a first-feature of the invention, a pulse E is derived from the transmitter trigger pulse A by means of a chain of circuits 27, 28, 29, 31, 32, 33, including an adjustable delay device 32 and is combined with pulse B is network 26. Delay device 32 is adjusted so that, with the radar set operating at the correct level of performance, pulse E is located on the flat top of pulse B at the right-hand extremity. Any reduction of performance reduces the width of pulse B and causes pulse E to ride on the exponential trailing edge. The resulting fall in amplitude of the combined pulses is detected by means of a trigger circuit 34 whose triggering level is adjusted appropriately by a bias control 36 and whose output controls indicating lamps via. a circuit 37. According to a second feature of the invention, trigger circuit 34 is rendered inoperative by means of an inhibiting potential when the level of noise at the output of the receiver exceeds a predetermined amplitude. The output of the video amplifier 24 is applied to a circuit 39 which suppresses signal components of the lower frequency range occupied by radar pulse components and passes the higher frequency components comprised of noise. These components, after amplification are rectified at 38 to provide the inhibiting potential. Fig. 2 (not shown), gives a detailed circuit for units 34, 36, 38 and 39.

Title: Formation of soldier joints across gaps
IPC: B23K1/00
Filed: 1970-05-11
Abstract: 1298399 Soldering; continuous casting; assembling components to circuit boards BURROUGHS CORP 11 May 1970 22663/70 Headings B3A B3F and B3R [Also in Division H2] In establishing a solder connection between a conductive pin 1 and a conductive plate 4, a preform bridge 6 of material which will not melt at the soldering temperature is used to span the gap between the pin and plate and heat is applied to solder in contact with the bridge 6 to form the connection without melting the bridge. A ready-made bridge structure can be used. In the form shown, this comprises bridge preform 6 sandwiched between solder layers 7, 8. In other forms, a bridge preform has a layer of solder on one side only (Fig. 2C, not shown); or bridge preform supports a solder layer on one or both wides through intermediate flux layer(s) (Figs. 2B, 2D, not shown). The material of the bridge is easily wetted by solder; it can be conductive, e.g. copper. A hole suitable to receive the pin 1 is punched through the structure prior to its use. Where the bridge structure comprises one or more solder layers directly on the bridge preform, it can be made by electro-plating. Alternatively, it can be made by a continuous casting process followed by rolling (Fig. 4). A copper wire 20 is fed through a solder-filled funnel 16 the outlet of which is supplied to a cooler 18, e.g. for cooling to -43‹ F. Forming rolls 19 then produce the sandwich structure. Flux can be introduced, if desired, between the wire and solder, e.g. Sn-Pb alloy, in the funnel. It is not necessary to use a ready-made bridge structure; instead the bridge preform, after positioning over the pin and plate, can be contacted by solder to which heat is then applied to form the joint. Solder of 63% tin, 37% lead can be used.

Patent GB-228059-A (GB)
Abstract: 228,059. Schlage, W. R. June 16, 1924. Latches, sliding.-In a mortise latch in which the bolt is contained in a casing at right angles to the casing containing the operating mechanism, the tail of the bolt has a pair of projections engaged by the retracting mechanism when the casings of the bolt and operating mechanism are engaged. All the component parts are made of stamped sheet metal. The latch bolt 45 slides in a cylindrical casing B inserted into a hole in the door and secured by screws passed through an endplate 43. The casing has lugs 44 engaging with edges 7 of the cylindrical casing a of the actuating mechanism when this is inserted into its hole in the door at right-angles to the latch polt casing B. The casing B is closed with a disc 49 through which passes the bolt shank 46 and upon which abuts the latch-actuating spring 48. The bolt shank has lugs 47 engaged by fingers 31 of a member 30 upon which the followers act. The member 30 slides in a guide member 18 attached to the disc 13 by hooks 25 engaging slots 15. A spring 33 between a lug 26 on the guide member and a lug 32 on the member 30, keeps the member 30 in its latch-shooting position. The springs 33, 48 therefore work together and the latch can still function if either is broken. The disc 13 with the guide member 18 containing the member 30 is provided with handle spindles 34, 35 which each have a lug 37 strengthened by back-turned parts 38. The spindle 35 is retained by the lug 39 engaging behind the disc 13 after passing through the bearing 12, slots 16, 17 being cut in the disc 13 to allow the passage of the lugs 38, 39. The lug 39 of the similar spindle 34 engages behind the face of the guide 18, no recesses 38, 39 being necessary on account of the fact that the spindle can be tilted in assembly. The assembly is then fitted into the casing a, the spindle 34 passing into the bearing 8 and the flanged edge 11 bent over the edge 5 to secure the parts together. Lugs 23 on the guide member have tapped holes 24 which come opposite holes 51 in the casing a so that when a clamping plate C is fitted over the bearing 8 from the opposite side of the door and screws passed through holes therein into the holes 57, the whole can be tightened up. A rose plate 40 can then be fitted.
