Filed: 1944-06-08
Abstract: 582,586. Wiring packages &c. POWER & SONS, Ltd., F. A., WALLIS, A. R., and PADMORE, J. N. June 8, 1944, No. 10974. [Class 45] A package strapping machine has a movable wire gripper 9 mounted on an arched carrier plate 21, itself mounted on the tensioning hand lever 10 of the machine by a pivot 21a above the pivot 10a of the latter on the base casting and pivotally connected to the base casting by an arm or radius rod 23 so that the carrier plate 20 is moved as it were on parallel links, when the hand lever 10 is moved. The carrier plate 21 carries a pivoted cranked plate 27 which supports the upper jaw b of the gripper 9 and a stop formed by the pivot 25 of the arm 23 engages a cranked end 29 of the plate 27 on the return of the hand lever 10 to the left. This action tilts the plate 27 in the direction of the arrow x and permits insertion of the wire in the gripper 9 when placing it around the package without separate manipulation of the gripper. On the wire tensioning stroke (to the right) of the lever 10 the wire is held in the gripper 9 by the action of a spring plunger 30 which is located in the carrier plate 21 and bears against the flange 29 thus tending to rotate the plate 27 in the direction of the arrow x so urging the upper jaw 9b of the gripper against the lower jaw 9a which is integral with the carrier plate 21. The lower jaw 9a is rounded on its upper face to guide the wire into position when it is being passed round the package. The carrier plate 21 and handle 10 are returned to the left by a spring pressed plunger 32. Specification 489,728 is referred to.

Title: Method and apparatus for stamping out a strip of synthetic plastic material
IPC: B29C53/48
Filed: 1958-04-10
Abstract: 870,338. Moulding sliding-clasp fasteners. INDUSTRIEHOLDING UND HANDELGESELLSCHAFT. April 10, 1958 [April 12, 1957], No. 11418/58. Class 87(2). Sliding-clasp fasteners are stamped out and moulded from strips of synthetic plastic materia carried between reciprocable transport elements by a process in which the stamping and moulding are effected during forward movement of the strips by dies moving with said elements and the strips are maintained stationary during the return movement of the dies and elements. Bars 4 and 5 are so mounted on eccentrics that the resulting in-phase oscillatory motion causes them to act as transport elements for strips 17 which are fed through a guide 16. Each strip is gripped by a spring-loaded stripper 10, pressed against cutting plate 14 and pierced by stamping die 9 which travels forward with it. The stamped out strip 18 is then held stationary by the stopping of feed wheels 36 while the die 9 and plates 4 and 5 move back and outwards, and then passes to a moulding section where it is moulded in three stages by dies 26, 27 and 28 with the aid of a spring-loaded lifter 29 between each stage. The dies are carried in forming members 19 and the process is similar to the stamping stage with the oscillatory motion being transferred from bars 4 and 5 via joints 23 to one end of actuators 22 which are connected to members 19 by springs 20 and pins 21. The other ends of actuators 22 slide in guides 24. The strip 18 is then bent by a pincer-like tool 30 into the shape 34, moved past a cooling stage 35, and then engaged by intermittent feed wheels 36.

The top closure of a reactor vessel comprises an outer rotary shield carrying an inner eccentrically mounted rotary shield, the axis of the outer shield being adjacent to both the peripheries of the reactor core and the inner shield, such that the inner shield is rotatably displaceable substantially clear of the core zone. The fast reactor is surrounded by a steel lined concrete biological structure 11, 13, 18, housing four heat exchangers 16 with pumps 17 (liquid sodium primary and secondary coolant), and a boronated graphite neutron shield 25 separating them from the reactor vessel 15. Outside pressurized containment vessel 12 is a fuel handling facility 26, connected through a stopvalved charge shoot 33 to reactor top handling facilities. The stainless steel reactor vessel 15 is suspended from the top section 18 of the biological shield, and is interconnected with the heat exchangers through radial coaxial ducts 35. Upward movement of the outer rotary shield is restrained by energy dissipation devices 46, which prevent a pressure surge in the reactor vessel lifting the suspended rotary shield. Core support structure 36 comprises (Fig. 3) a cylindrical core zone 37 surrounded by an annular breeding zone 38, and a storage zone comprising a cylindrical charging zone 39 and a decay storage zone 41. Upper and lower breeding zones are provided by means of fertile material carried in the end portions of the fuel elements. Fuel handling and control rods.-Control rods 48 and drive motors are mounted on the inner rotary shield 44 and consequently the control rods must be inserted and disconnected (shutting down the reactor) before either of the inner and outer rotary shields are rotated. The outer rotary shield carries a second eccentric rotatable shield 45, the charge plug, located, during normal operation, over the changing zone 39. The charge plug contains four charge tubes located on different radii, each tube including an isolating valve; thus during reactor operation, fuel elements may be transferred to and from the charging zone and rotary fuel magazine 32 by charging machine 22. When the reactor is shut down, fuel and fertile elements may be transferred between the various zones in the support structure 38 by rotation of both the inner and outer plugs to position a fuel handling machine 53 carried on the inner plug. In a modification (Fig. 4, not shown), the control rods are carried on the outer rotary shield, and the inner rotary shield, carrying change tubes and charging machine, is normally positioned over the charge zone 39.
