Title: Rapid action clamp for circuit board - consists of clamping roll brought into open position by manual depression of support against spring pressure
IPC: H05K13/00
Filed: 1979-12-06
Abstract: A clamping element can be pressed against a clamping body for the circuit board. The clamping element is in the form of a clamping roll (3), movable manually against a support (5) on the clamping body (2), in order to provide an open position for reception of the circuit board. The manual setting is actuated against a pressure of a spring (8) on the clamping body. The resetting force of the spring provides the clamping roll retraction against an inclined guide face which defines an upwards tapering retention gap in the clamping body. Pref. the support for the clamping roll is a bracket, straddling the roll by its two shanks and supporting it by its free ends. The middle part of the bracket is screwed to a guide bolt (7), which may be inserted into a vertical bore (9) of the clamping body. The inclined guide face (4) may extend horizontally and may define the max. thickness variation of the board.

Title: Coke oven door seal - with horizontal and stronger vertical springs acting on knife edge
Inventor: DIX KURT
IPC: C10B25/16
Filed: 1980-04-26
Abstract: A coke oven door for coke ovens of the horizontal chamber type is sealed against the door frame by a knife edge which is first adjusted roughly by hammer blows. Short thrust bars, held by hook bolts to the door periphery, contain horizontal spiral or disc springs which urge the knife edge against the door. Longer and stronger vertical spiral or disc springs act on a stem which urges the knife edge against the door frame. This ensures an automatic fine adjustment of the knife edge seal and a compensation for dimensional changes between door and door frame during the carbonizing period. The new seal can be subsequently added to existing doors.

Title: Heat energy storage system by thermal decomposition of hydroxide - in conjunction with hydrous hygroscopic substance
Inventor: GATH NICOLAS
IPC: F24J3/00
Filed: 1980-06-30
Abstract: Heat energy storage utilises the thermal decompsn. of a hydroxide, e.g. Ca, Mg or Ba hydroxide, into an oxide and water vapour, which are sepd. and contacted again later. The water is removed by the oxide from a hydrous hygroscopic substance, e.g. NaOH, KOH or KCl, and the hydroxide formed is reconverted to the oxide by heating. This procedure is repeated until the hygroscopic substance is in the form of a highly conc. soln., solid hydrate or in the state free from water of hydration, then heat is recovered from this dehydrated hygroscopic substance by exothermic reaction with water and/or water vapour. The hydroxide is heated above 300 deg. C by conc. sunlight. The reaction takes place in a closed system under partial vacuum. The material input and heat loss are slight. The system can be used in central heating.

Title: Pneumatic proportional regulator with manual and automatic modes - has balanced pneumatic stage that responds to pressure differential to control output
Inventor: ROTH GUENTHER ING GRAD
IPC: G05B7/04
Filed: 1980-07-02
Abstract: A pneumatic proportional regulator includes facilities for manual and automatic modes of operation. Typically, a reference pressure is used to define, for example, a temp. A monitored pressure is proportional to the actual temp. By pressure comparison, a differential value is generated to control the process. In the fundamental system, the reference (Soll) and actual (Ist) pressure operate on a balanced mechanical system. When the demand exceeds the output a nozzle (16) is constricted to increase the pressure in the line to the regulating stage (24). A changeover switch (22) allows the unit to be operated in either the manual or automatic mode.

Title: Environment-sealed interrupter chamber for electrical contacts
Inventor: SAUER HANS
IPC: H01H45/04
Filed: 1982-01-08
Abstract: The invention relates to an environment-sealed interrupter chamber containing electrical contacts and at least one porous getter. The gettering substance used is a substance which has the power to adsorb substances which form contaminating films on the contacts. The purpose of using getters in tightly sealed interrupter chambers for relays and switches is to keep molecules, such as organic compounds, which form contaminating films away from the contacts and to bind them for a long time and selectively to themselves. The invention takes this into account in that the chosen pore size of the getter in the interrupter chamber is predominantly larger than 3 nm and smaller than 100 nm and in that the mean value of the pore diameter is approximately in the 7-20 nm range.

Title: Vacuum shaft furnace
Inventor: SCHMETZ PETER DIPL-ING
IPC: F27B5/06
Filed: 1982-03-10
Abstract: The vacuum shaft furnace serves for the heat treatment of workpieces and is provided with means for cooling the heat-treated charge by means of a stream of gas which is conducted via openings through the inside of the preferably cylindrical heating chamber and is circulated outside the heating chamber within the closed furnace housing by a gas blower over a gas cooler. In order to be able to adapt the flow of gas in optimal manner to the specific nature of the batch and to obtain a uniform cooling rate within a charge, closable openings (27, 30) are arranged on the one hand in the bottom (7) and in the cover (6), for a vertical flow in the heating chamber (4), and closable openings (23) are arranged on the other hand at opposite places in the side wall (5) of the heating chamber (4) for a horizontal flow, said openings (23) lying above one another over the entire height of the chamber. For further assistance in achieving this goal, the bottom (7) of the heating chamber is rotatably mounted around the vertical axis of the chamber and provided with a rotary drive (14, 15, 16). As a result of this design, the circulated cooling agent can flow vertically or horizontally within the heating chamber (4) or else alternately in both directions during the cooling process. <IMAGE>
