Title: Improvements in or relating to photo-type composing machines
Inventor: WILLIAMS JOSEPH HENRY
IPC: B41B27/32
Filed: 1958-02-11
Abstract: 852,991. Photo-type composing machines. MONOTYPE CORPORATION Ltd. Feb. 11, 1959 [Feb. 11, 1958], No. 4475/58. Class 98(1) A photo-type composing machine employing a record strip having space signals in the same line as the character signals for the next character, has mechanism for determining the positions of the character images on the sensitized sheet comprising first, second and third racks which drive first, second and third pinions, driving means for operating the first rack for character signals and another driving means for operating the other racks for space signals, stroke varying means for the first rack operable in accordance to the required character width and stroke varying means for the second and third racks operable in accordance with the justification signals to give coarse and fine adjustments of the interword spaces, and differential gearing for combining the rotations of the pinions, changeable in its ratio to allow alteration of the character and interword spacing sizes. In the machine shown character images are formed by a lens 33 and mirror pair 32 on a sensitized sheet mounted on a drum 35. The mirrors 32 are movable unidirectionally by means of a rack 31 through skew gears 27 and change gears 25 by pinion 15c and/or pinions 15a, 15b. Pinion 15c is rotated by a rack 14c carried on a shaft 12c (Fig. 6). When shaft 12c is depressed the rack 14c is disengaged from pinion 15c by rotating arm 56 on a rocker 45c and the pinion is held in place by a locking rack 57c and a pawl 70 (Fig. 1). The amount shaft 12c is depressed is determined by which projection 41c of a number staggered circumferentially round a cylinder made of rings 39c. (each ring having one projection), engages the top of a post 44c. This is determined by a pinion 46c attached by a sleeve to pinion 49c operated by the rack bar 51c which is biassed rearwardly and movable in response to the character signals from a record strip. Pinions 15a, 15b are similarly operated by racks 14a, 14b (not shown) respectively, rack bars 51a, 51b (not shown) being movable in response to justification signals from the record strip. The rockers 45a, 45b, 45c are coupled together (Fig. 3) by a link member 56 as are the rockers of racks 57a, 57b, 57c by link 61 and both links are indirectly coupled to an arm 67 which is moved in a predetermined time relation with the driving means for slide members 17a (not shown), 17b, 17c of the racks 14a, 14b, 14c. The driving mechanism for reciprocating the slide members 17a, 17b (partly shown in Fig. 7) acts through a cam lever 69 which is connected to a lever 71 which is indirectly connected at 75b to the neck of sleeve 17b and (not shown) to sleeve 17a. A similar cam lever is similarly connected to sleeve 17c and both levers are operated by perforations in the record strip. The rack bar 31 is returned at the end of each line to the starting point for the next line by a cam-operated lever acting on a projection. Specifications 563,331 and 801,873 are referred to.

Title: Improvements in or relating to the fabrication of nuclear reactor fuel elements
Inventor: JONES HERBERT NOEL
IPC: G21C21/12
Filed: 1960-02-10
Abstract: 957,605. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 26,1961 [Feb. 10, 1960; June 2, 1960], Nos. 4788/60 and 19526/60. Heading G6C. In the manufacture of fuel elements comprising fissile material enclosed in a protective sheath, in which the sheath is subject to external pressurisation at an elevated temperature in order to form it into intimate contact with the fissile material, a longitudinal compressive stress is applied to the sheath by a clamp made of two or more materials in composite form so as to be matched in thermal expansion with the fissile material, the sheath thus being allowed to elongate by approximately only the same amount as the fissile material on heating during pressurisation. In the embodiment shown in Fig. 1, a fuel element 1 comprising a cylindrical uranium rod 2 enclosed in a magnesium alloy sheath 3 having external helical fins 4 is held in a clamp 8 formed of two tubular sections 9, 10 joined by a circumferential butt weld 11. Section 9 is of mild steel and is three times the length of section 10 which is of stainless steel. A screwed end cap 12 is fitted at the lower end of the clamp 8 and a quick-release end cap 13 at the upper end, the latter carrying a clamping screw 18 having an end flange 20 with an integral skirt 21. The fuel element 1 is clamped between rings 22, 23 which bear against the ends of the fins 4, clamping pressure being applied by turning down the screw 18 to finger tightness. The body of the clamp 8 is perforated by longitudinal slots 24 while the end caps 12,13 are perforated by holes 25, 26 respectively. Pressurisation may be carried out hydraulically by preheating in oil at 250C. and 100 psi for 15 min., the pressure then being increased to 12,000 psi and maintained for 30 min. Strain due to the clamp initially cooling faster than the fuel element on withdrawal from the oil is avoided by releasing the end cap 13 before cooling starts. When gas pressurising at 500C. is employed, the clamp should consist of half mild steel and half stainless steel. Where the sheath has circumferential fins, multistart helical fins of short pitch or a single start helical fin of short pitch, the loading cannot be applied in the above manner because it would then be localised on one fin at each end of the sheath. In such a case end fitments for applying the load to several fins at each end of the sheath where these are circumferential, or to several turns of the fin or fins where these are helical are used, an end fitment 6 formed in two complementary halves 7, 8 for use with a single start helical fin 10 being illustrated in Fig. 4.
