Patent DE-2406916-A1 (DE)
Title: Double seating valve for spherical nuclear fuel element supply - with cam operated seals to expand against seatings when closed
Inventor: CRAMER HEINZ DIPL ING
IPC: G21C19/20
Filed: 1974-02-14
Abstract: A double-seating cut-off valve for pipelines conveying solids entrained in gas, esp. for feeding spherical nuclear fuel elements to a reactor, is a rotary valve comprising a functioning component (I), a bearing plug (II) and a drive shaft (III) (for rotating the functioning components) passing through (II); all these are incorporated in a blind hole in a block acting as the valve housing. (I) has a passage through it, which is aligned with the two seatings to provide an open state and rotated, esp. through 90 degrees, for the shut-off position. (I) two seals on a line perpendicular to the passage which can be pressed by expanding elements against the valve seatings when the valve is closed. The drive for (III) is provided from an external motor with a gas-tight shaft seal. An integrated fail-safe device is incorporated and the valve can be dismantled even when the seals are in the expanded positions. The blind end of the hole acting as the valve body pref. has an abutment which co-operates with a projection on (I) to limit the rotation to 90 degrees. The seals are pref. expanded outwards by expanding jaws, esp. with plates between the jaws and seals. The expanding action may be provided by rollers at the end of each jaw running on spiral cam paths on (III) so that they move radially inwards or outwards as the shaft rotates. The valve thus fulfils both operating and safety functions, and even if the valve seals are not applied to the seatings, the closed position will prevent the passage of any solid articles, although gas may pass.

Title: Heat exchanger with closely packed seats tubes - modified to facilitate and in-service adjustments
Inventor: ECKER HANS
IPC: F28D7/16
Filed: 1975-04-22
Abstract: The main patent concerned a heat exchanger made up of tubes in narrow bundles with somewhat wider caps at each end: to save space the bundles were set at varying heights so that each cap rested against the shank of a bundle rather than against another cap. The finished unit was to be put inside the concrete shielding of a nuclear power plant, and as designed it would have been impossible to disconnect it wholly or partly had it developed a fault. By this patent of addition, therefore, one or more of the central bundles will be replaced by a single wide open tube to give access (a) to the joint by which the unit is connected to the rest of the plant and (b) to the ends of the pipes that connect with the individual bundles (so that a faulty bundle can be plugged off - by the design of the unit it cannot be withdrawn).

Title: Composite castor for household appliances - has rollers of different flexibility for working stability and free travel
Inventor: HUBER HEINRICH
IPC: B60B33/00
Filed: 1975-06-10
Abstract: The caster for domestic appliances especially for washing machines, has rolling elements (3, 4, 5) made from materials with different compressibility. The dia. of the roller (5) made of compressible material, is larger than those of the rolling bodies (3, 4) made of more flexible material, or vice versa. This caster ensures low rolling resistance and ground loading. When the loaded machine is operated, then the resistance to rolling and the friction on ground are high. The machine is readily moved about due to the harder part of the roller however, the flexible parts engage more firmly with the ground when the machine is loaded. This ensures high stability in operating e.g. a spin drier.
