Title: Rotary heat exchanger
IPC: F28D19/04
Filed: 1967-12-20
Abstract: 1,146,228. Thermal regenerators. FORD MOTOR CO. Ltd. 20 Dec., 1967 [21 Dec., 1966], No. 57853/67. Heading F4K. A rotary-disc type axial-flow, rimless, ceramic matrix for a thermal regenerator is rotated by a drive arrangement consisting of a ring gear 26 coupled to the matrix 10 by a plurality of resilient members such as spring clips 28, each having a part 42 engageable with the ring gear and another part engaged in a recess 30 in the matrix periphery thereby transmitting a drive from the ring gear to the matrix. As shown, the parts 42 of the clip comprise hooked portions which each engage the rounded end of a flange 46 projecting laterally from the ring gear (see Fig. 4). The arrangement is such that if for some reason rotation of the matrix itself is prevented, the clips 28 can ride out of the recesses 30 on to the outer peripheral surface 22 of the matrix thus preventing damage to the matrix structure by reason of a forced rotation of the ring gear.

Title: Valve for series connected radiators
IPC: F24H9/12
Filed: 1970-12-07
Abstract: 1331615 Valves V REATO 7 Dec 1970 [19 Dec 1969] 57951/70 Heading F2V A valve for series connected radiators in heating systems with a single feed tube comprises, a body 1; a member 9 for sealing against the first element 12 of the radiator; and a rotatable cylindrical member 2 formed with passages 3, 14 and 15. In the operative position shown, water entering the valve from an inlet pipe 5 flows through the passage 3 and a conduit 6 into the radiator and returns to an outlet pipe 7 via the first radiator element 12, and passages 13, 14. To shut the radiator off from the supply, the cylindrical member 2 is rotated so that passage 14 is closed, whilst passage 15 directly connects the inlet pipe 5 to the outlet pipe 7. A screw 18 can be adjusted to throttle the flow in passage 15 to produce a loss of head equiva-  lent to that of a radiator. A groove (21, Figs. 2 and 3, not shown) in the rotatable member 2 enables rotation thereof whilst the screw protrudes into the passage 5. The rotatable member 2 can be set to a position intermediate the fully open and fully closed position, whereby some of the flow passes to the radiator whilst the remainder passes directly to the outlet pipe.

Filed: 1978-11-17
Abstract: A device for automatically compensating for wear in a friction clutch of the kind which is released by a pedal-operated control lever (6) acting on a cable (5) through an intermediate element (9) articulated to the control lever, has a toothed sector (10) on the intermediate element which meshes with a pinion (15) carried by structure (11) which is pivoted on the intermediate element about the axis of the toothed sector. When the control lever (6) is depressed to disengage the clutch the pinion is engaged by a stop surface (18) which prevents rotation of the pinion, so that the intermediate member moves with the control lever; when the control lever returns to its rest position, however, the stop surface disengages from the pinion, allowing the latter to rotate, so that the intermediate member (9) can assume a new position relative to the control lever, thereby taking up wear in the clutch (1). <IMAGE>
