Abstract: 874,623. Thermal regenerators. GENERAL MOTORS CORPORATION. Aug. 25, 1959 [Sept. 10, 1958], No. 11205/60. Divided out of 874,622. Class 64(1) In a thermal regenerator having an annular matrix 33, a rim seal comprises an arcuate seal support coaxial with the axis of rotation of the matrix and having a circumferential succession of flat faces, and seal blocks loosely held against the flat faces and spring-urged against a radial edge surface of the matrix. Each flat face preferably terminates in a step against which one end of a seal block abuts, successive seal blocks being overlapped. In the form shown, in which the regenerator is associated with a gas turbine engine, an axialy extending seal 370 separates the higher pressure air and lower pressure heating gas sides of the matrix 33. On the air side (see Figs. 3 and 4) in which the air flows radially inwardly, each seal block 587 of the rim seal is loosely held in position on the arcuate support 580 by the radial abutment 589 and by a retainer 584, the retainers and support being secured by studs 582 and nuts to a wall 51 of the'regenerator housing. Each retainer embodies a spring finger 586 which engages in a cavity in the block to prevent it from falling out of place. Each seal block is chamfered at one end 591 where it overlaps an adjacent block. Leaf springs 596 urge the block against the radial end face of the matrix, and the radially inward air pressure biases the block against the face the arcuate support 580. On the gas side (see Figs. 3 and 6) where the flow is radially outwardly, each seal block 558 of the rim seal is loosely held in position on one of the faces of the arcuate support 551 by a retainer 556 again provided with a spring finger engaging in a cavity in the block to prevent it falling out of place. The pressure differeritial across the matrix biases the seal block against the face 559 of the arcuate support 551. One end of each seal block abuts one of the radial abutments 561 on the arcuate support 551 and this in conjunction with a lip 566 formed on one end of the retainer restrains circumferential movement of the block. Springs 572 supplemented by the gas pressure urge the seal blocks towards the radial edge of the matrix 33.

A current-limiting cartridge fuse having a casing i, Fig. i, and end caps 4a, 4<SP>b</SP>, has a silver link 3, perforated at 3a and a tin rivet 5 secured in one of the perforations. The cartridge is filled with pulverulent arc-extinguishing material, such as quartz sand, having a grain size falling within the range 7-34 mesh/cm., preferably between 11 and 15 mesh/cm. A mixture of grain sizes within the said range may be employed. The internal volume of the casing I is in the order of I/4oo to I/5oo of a cubic inch per kVA capacity and the link is adapted to limit the maximum continuous current of the fuse to less than 36 amps. Fig. 3 shows a modification wherein a filling of chalk 6 at one end of the casing surrounds the rivet 5 and is separated from the arc-extinguishing material by a loose fitting washer 7. At low current interruptions carbon dioxide formed from the chalk is mixed with the arc products which mixture permeates through the arc-extinguishing material. It is stated that the fact that this mixture has a high heat conductivity and tends to increase the pressure inside the cartridge, increases the dielectric strength of the mixture within the casing in conformity with Paschen's law. A number of fuses constructed as above may be assembled in a single casing, Fig. 4, (not shown), to form a composite fuse similar to that described in Specification 7o3,3o3. Specification 7o2,582, also is referred to.
