Abstract: A bird feeder (10) for all seasons having a seed reservoir (12) for gravitationally delivering food in pellet or seed form to an inner bell (20) positioned within an outer bell (22). The inner bell (20) and the outer bell (22) rotatably mate with each other and are shaped to provide a closed mode for storage and an open mode for food access. In the open mode the outer bell (22) is rotated so that arch apertures (44) in the inner bell (20) align with inverted arch apertures (66) in the outer bell (22). In the closed mode the arch apertures (44) of the inner bell (20) align with the outer cylindrical wall (54) of the outer bell (22). A damper (24) controls seed flow, and a cover structure (18) with a sloping roof (74) retains the inner bell (20) and outer bell (22) in a rotatable position relative to each other.

Abstract: A disc drive arrangement 10 for accessing information from and recording information onto a disc 25 to be retained in a cartridge 27 which comprises a carriage 24 for mounting and transporting the head 26, 28 accurately relative to the cartridge 27. The carriage 24 includes a base 100 upon which is mounted the head 26, 28 and cylindrical roller bearings 214, 216, 218, 220 and 222. The roller bearings 214, 216, 218, 220 and 222 roll on a plurality of hardened rods 228, 230 which are mounted on a track 102 which is affixed to the floor 16 of the disc drive 10. At least one of the roller bearings 214, 216, 218, 220 and 222, is resiliently mounted relative to the base 100 in order to evenly distribute the load placed by the base 100 on the track 102. Further any potential contaminants collecting on the rods are urged to one or the other side of the rods 228, 230 as the cylindrical rollers 214, 216, 218, 220, 222 roll on said rods thereby insuring accurate position of the head 26, 28.

Abstract: A disc drive arrangement 10 for accessing information from and recording information onto a disc 25 retained in a cartridge 27 comprises a linkage 22 operatively connecting a door 18 to a head 26, 28 mounted on a carriage 24 for urging the head 26, 28 away from the cartridge 27 when the door 18 is opened. The linkage includes an arm 154 with a cam surface 158 which urges the head 26, 28 away in an accelerated manner. A dashpot 188 operably connected to the head 26, 28 and linkage 22 allows the head 26, 28 to dampingly settle on the disc 25 after the dome 18 is closed.

Abstract: The invention is a unitary solid interface adapter for placement at the bottom of a wok. The adapter is made from a thermally conductive material and has an exterior shape substantially in the nature of a frustum of a cone. The upper surface of the adapter is concave in the shape of a sector of a sphere such that a traditional wok will nest therein with approximately equal contact over the entire interface therebetween. The bottom surface of the adapter is substantially flat for maintaining a solid stable perch on either electrical stove elements or gas range lattice support structures. The bottom of the adapter may be provided with anti-slip protrusions which prevent the adapter from sliding on the top of the range element. The side of the adapter is angled outward in a conical fashion such that the heat generated by a smaller area of element at the bottom surface of the adapter may be delivered to a greater area of the wok surface for maximum usable cooking area.

Abstract: A disc drive arrangement for accessing information from and recording information onto a disc retained in a cartridge comprises a housing, a door, at least one reading and recording head, a carriage for mounting and transporting the head, and linkage operatively connecting the door to the carriage for urging said head away from the cartridge when the door is opened. As this linkage is mechanical, the head can always be urged from the disc even during power failure so that if the cartridge is removed, the head and the information on the disc are not damaged.
