Class 64(1) [Also in Group XXXIV] A rotary regenerator comprises a rotor 52, Fig. 1, a stationary casing 40 and a bearing 46 for rotatably supporting the rotor at its outer periphery, the rotor comprising a plurality of sector shaped baskets 54, Fig. 2, positioned in abutting relationship so that the radial sides 56 of the baskets define partitions extending between the inner and outer peripheries of the rotor while the transverse ends 58, 60 of the baskets form the inner and outer rotor walls. The baskets are filled with spaced vertical plates 64 of heat absorbing material and are connected by bolts or rivets 62 to form an integral assembly. This assembly may be supported on the bearing 46 by radial brackets 68 provided on the baskets or it may rest on a framework (not shown), made up of T-section beams welded into the form of a polygonal spoked wheel, the spokes extending beyond the outer periphery of the wheel to rest on the bearing 46. Alternatively, the assembly may be suspended from the spokes 92, Fig. 7, of the framework by angles 96 and bolts 98. The framework may be filled with heat absorbing plates of different material. As shown in Fig. 8, the bearing 46, which may be arranged at the lower end of the rotor 52, comprises a fixed lower member 74 and an upper rotatable member 48 each of which preferably consists of a number of arcuate elements 108, Fig. 2. Balls 106, Fig. 8, held in evenly spaced relation by a retainer 116 run on arcuate lengths of piano wire 104 mounted in recesses 102, 110, the joints between the lengths of wire being staggered. The elements of the member 48 are connected by arched springs 118 provided with guide means 120 in which extensions 100 of the side walls of the baskets are free to slide radially and carry pins 112 for engagement by a driving gear 114. Alternatively, the baskets may have arcuate end walls provided with horizontal flanges which rest on the member 48 and carry the pins 112 or a friction drive may be used. To facilitate maintenance, the casing 40 may have a door to permit replacement of a basket while a ring 50 surrounding the bearing is made up from detachable segments. Peripheral and radial seals 124, 126 are provided between the rotor and fixed end plates 12 and 14 which have sector-shaped ports 16, 18, 24 and 26 connected to ducts 20. 22, 28 and 30. Specification 829,904 is referred to. Reference has been directed by the Comptroller to Specification 733,728.

Abstract: 1,058,165. Photo-electric tracking systems. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). Feb. 28, 1964, No. 8374/64. Heading H4D. In a radiation detection system (e.g. for tracking aircraft or missiles) a rotating reticle (2, Fig. 4) is followed by a spectral filter (6). which may be a wedge of fused silica, cyclically traversed with a small movement across the radiation path to a cell (7) and adjusted to its mean position by a servo system controlled from the detected output of the cell. The ensuing reduction of background radiation is explained (Figs. 2, 3 and 6). In the first embodiment (Fig. 4) the output of an amplitude-modulation detector (10) is fed to a phase-sensitive detector (14) the reference signal input to which is from an oscillator (13) which also energizes means producing the " jitter " of the spectral filter (6). In another embodiment the servo system is jittered about its mean position (Fig. 5). The radiation may be infra-red, visible light, or ultra-violet.
