Title: Fuel bundle with removable rods
IPC: G21C3/33
Filed: 1971-04-19
Abstract: 1350628 Fuel elements GENERAL ELECTRIC CO 19 April 1971 [30 March 1970] 25466/71 Heading G6C In a removable rod arrangement for a nuclear reactor fuel bundle providing ready insertion and removal of the removable rods without disassembly of the fuel bundle, the removable rods  are accurately positioned by complementary positioning surfaces and retained in position by a spring-loaded, tapered pin and pin seat. The upper end of a removable rod 11 (1) located in the interior of the fuel bundle is shown in Fig. 3, this rod including a hollow body portion 38 which may contain fuel material, neutron absorber or poisons. or mixtures of these, with or without diluent material. The usual rod retaining fitting or receptacle 16 of the upper tie plate is omitted to provide a passage for the rod 11 (1) and a shoulder 24 with a rod positioning surface 26 and a pin seat 27 is formed on an adjacent receptacle 16. An extension 22 (1) of the upper end plug 18(1) of the rod is fitted with a slidable sleeve 28 formed with a rod positioning surface 29 abutting the rod positioning surface 26 of the shoulder 24. A headed retainer pin 30 fixed to the sleeve 28 engages the pin seat 27. The sleeve 28 is spring-loaded by a coil spring 31 between the sleeve 28 and the upper end plug 18(1). The retainer pin 30 and the pin seat 27 are formed with tapered surfaces 36, 37, respectively, to provide a component of the force of spring 31 in a direction to urge the surfaces 26, 29 together. The angle of taper of the pin seat 27 is slightly less than that of the pin 30 to provide a line contact between the pin and seat. This is an aid to disengagement in the event of build-up of corrosion deposits. To insert the rod 11 (1), it is passed through the upper tie plate until its lower end plug engages the lower tie plate and the spring 31 is compressed by moving the sleeve 28 downwards until the pin 30 is below the shoulder 24. The rod is then moved towards the shoulder 24 to place the surfaces 26, 29 in contact, whereupon the sleeve 28 is allowed to move upward under the force of spring 31 as the retainer pin 30 enters and engages the pin seat 27. Where a relatively large number of removable rods are desired in the peripheral rod positions it is advantageous to employ peripheral bars (40) (Figs. 5 and 6, not shown), to provide rod positioning surfaces and retainer pin seats for these peripheral rods. To provide passage for the rods, the receptacles 16 of the rod positions to be occupied by the removable rods are omitted and the peripheral bars are fixed to the corner and/or any remaining peripheral receptacles 16.

Filed: 1959-07-29
Abstract: 917,216. Obstetric appliances. HEYNS, O. S. July 29, 1959 [July 31, 1958], No. 26053/59. Class 81 (2). A device for applying reduced pressure to the abdomen during the early stages of childbirth comprises a flexible sack-like enclosure 10 which, at its upper end 12, closely engages around the patient's chest and back and has stiffening means 24 which holds it clear of the abdomen. The interior is connected through a tube to an evacuating pump and this causes reduced pressure to be applied to the abdomen while the remainder of the enclosure collapses on to the legs &c. and prevents these parts being subjected to the low pressure. The stiffening means may be in the form of hoops, as shown, a rigid frame comprising a backing plate coacting with an arched front section or an annular hollow cushion which is rendered substantially rigid by fluid pressure. In a simplified form of the apparatus, which avoids the use of an external pump, the stiffening member is made from stout rubber, with its front part of domed shape. This is forced inwards to expel the enclosed air through a non-return valve and is then allowed to return to its original shape, so inducing the desired degree of vacuum. Specification 839,965 is referred to.
