Patent ES-371417-A1 (ES)
Title: Nuclear fuel retainer
IPC: G21C3/18
Filed: 1969-09-11
Abstract: A fuel element has a cup-shaped retainer between the fuel and a space for accommodating fission product gases, the retainer having a bottom portion abutting the fuel and an upstanding portion resiliently engaging the fuel element casing so as to resist axial movement of the fuel. The resilient force of the retainer is such as to prevent displacement of the fuel during shipping and handling operations, while allowing axial displacement of the retainer in response to longitudinal expansion of the fuel during operation. There is at least one opening in the bottom portion of the retainer for passage of fission product gases. The retainer may be split by a slot down one side and across the bottom, or by two pairs of opposed longitudinal slots, in order that the resilient force will be more constant over larger changes in diameter than with a retainer of plain cup form.
Patent ES-382601-A1 (ES)
Title: Ignition distributors
IPC: F02P7/06
Filed: 1970-08-08
Abstract: A method of assembling an ignition distributor includes the steps of engaging an annular timing plate with an annular base plate. Mating surfaces on the two plates locate the timing plate for angular movement on the base plate when the two plates are engaged. A deforming tool is engaged with three ears or tags formed on the base plate, and the ears are deformed into contact with the surface of the timing plate remote from the base plate. The physical properties of the ears are such that when the deforming tool is removed, the inherent resilience of the ears causes the ears to flex away from the timing plate through a predetermined distance so that a predetermined clearance exists between the timing plate and the ears. The predetermined clearance permits a predetermined axial freedom between the timing plate and the base plate. In a modification the timing plate is provided with upstanding projections into engagement with which the ears are deformed, the ears then flexing away from the projections when the deforming tool is removed, so that the clearance is equal to the heights of the projections plus the mount by which the ears flex.
