Patent GB-803677-A (GB)
Abstract: 803,677. Regulating air supply. CARRON, CO., and PHILIP, A. R. July 1, 1957 [March 29, 1956], No. 9913/56. Class 126 A duct 4, Fig. 1, supplying primary air to the firebox 3 of a solid fuel cooker, extends beneath a heat accumulator 2 forming part of the base of the oven 1 to the ash box 5. A damper 6 in the duct is operatively connected by one end of a lever 7, Fig. 2, to a thermostat 8 fixed to the wall of the oven, the other end of the lever being mounted on a pivot 9A for movement on a horizontal axis. The compression of a spring 10, mounted between the damper and the lever 7 is altered by movement of a vertical rod 11 depending from the top plate 12 of the cooker, so that expansion of liquid in the bellows (not shown) of the thermostat in response to a rise in oven temperature sensed by a bulb 13 in a housing 14 within the oven, swings the lever 7 about the pivot 9A in opposition to the spring 10 to move the damper 6- to the open position.

Title: Method of welding
Inventor: HAGAN DENNIS
IPC: B23K11/04
Filed: 1982-03-04
Abstract: When two components 1, 2 are welded together, e.g. by magnetically impelled arc butt welding, at two abutting faces, tolerance "stack-up" is avoided by determining a dimension (a+b) corresponding to a length measured across the two components when the faces are in abutment, and comparing it with a desired value or range of values for the dimension. The welding conditions are then selected so that the value (d) of the dimension in the finished article is equal to the desired value, or falls within a desired range of values. <IMAGE>

Title: Mechanism for retaining two members in two different relative positions
Inventor: RICHMOND ALAN JOHN
IPC: F16H35/14
Filed: 1982-03-25
Abstract: A push-push mechanism for retaining first and second members, which are movable relative to each other against a bias, in two different relative positions, such that application of external pressure moves the two members from a first position to a second position against the bias. Upon release of this pressure the members are retained in this second position until further external pressure is again applied and released, at which time the members are urged by the bias to resume the first position. The mechanism comprises a cam follower (8), attached to the first member (1), a cam track (9) having first and second cam follower retaining parts, at least one guide path for the cam follower interconnecting the first and second retaining parts connectable to the second member, and biasing means (3), for biasing the first and second members such that the cam follower is urged into either one of the cam follower retaining parts. The guide path or guide paths are constructed such that the cam follower is constrained to move alternately between the cam follower retaining parts as the two members are moved relative to each in a reciprocating manner by the intermittent application of external pressure. <IMAGE>
