Title: Fire damper for ventilation ducting - has fusible plug holding sprung cranked lever for automatic or manual operation
Inventor: KIZAOUI JASSIEN DR ING
IPC: A62C2/24
Filed: 1975-12-02
Abstract: The damper blade (14) pivots on a shaft (13) within a casing (10) in a run of ventilation ducting. The shaft projects outside the casing and is linked to an operating lever (18). a spring (19) tends to close the damper. A knob (40) on the other end of the lever (18) rests against a cranked lever (30) which holds the operating lever (18) in the open position. The cranked lever (30) pivots on a pin (29) which is kept in place by a fusible plug against the force of a spring. When the plug melts the pin moves axially and frees the cranked lever which allows the operating lever to close. Manually the cranked lever can be pivoted out of the way to allow the operating lever to close.

Title: Wet steam vertical dryer with superheater - has inclined superheaters for reducing pressure drop and vessel deformations
IPC: F22B37/26
Filed: 1977-01-26
Abstract: The wet steam dryer has also superheater for dryed steam. The plant for this purpose has uniform temperature which eliminates thermal stresses and distortion of the vessel walls.

Title: Telephone equipment push button key - uses injection moulded synthetic material button with attached synthetic material spiral spring
Inventor: NIEDERHOEFER KARL-HEINZ ING GR
IPC: H01H13/52
Filed: 1977-04-29
Abstract: The pushbutton (1) has a flexible arm (5) whose end (6), hooks under a projection (7) in the button housing (8). The contact (4) is a curved rectangular spring which flexes when certain pressure is applied to the button. The ends (11 and 12) of the contact spring flex upwards and make contact with terminals (13, 14). The movement of the pushbutton in the case of a rigid construction is about 1mm. To increase the movement of the button when pressed the lower part (2) is in the form of a spring (16). At the moment the button is pressed the spires of the spring (16) are compressed so that the movement of the button is increased until the contact spring (4) is actuated. The characteristic of the point of critical pressure does however remain the same. The button (1) had its lower part (2)(16) are made from an injection moulded synthetic material.

Title: Pebble bed reactor core supported on graphite block structure - with hollow columns below discharging hot gas through numerous ducts
Inventor: HENSSEN JOHANNES
IPC: G21C1/07
Filed: 1977-09-23
Abstract: A support structure for the core of a gas-cooled, high-temp. reactor housed in a cylindrical pressure vessel vault, esp. a pebble bed reactor, consists of a bed of graphite blocks arranged in stacks, each supported on a circular column, the stacks of blocks are linked together to form a solid base for the pebble bed, while the support columns stand separate from one another in an open space beneath the core support structure. This open space serves as the hot gas header chamber leading to the gas discharge ducts. The graphite blocks of the core support structure contain a large number of ducts for hot gas flowing down from the core; each column is a hollow cylindrical column, the central duct of which receives the gas descending through the adjacent blocks from the core and discharges the gas through a large number of radial ducts uniformly distributed in different vertical planes. Due to the large number of outlets for the gas from the hollow support columns, thorough mixing of the hot gas within the header chamber takes place, partic. the hotter gas from the central region of the core with the cooler gas from the outer regions. In this way the gas is thoroughly mixed before it reaches the outlet ducts from the vessel.
