Title: Spiral in chimney extracts heat from coal fire flue gases - warmed air returns to same room, supplementing fire
Inventor: ESSIG KLAUS
IPC: F24C15/00
Filed: 1974-10-30
Abstract: Air from a living room heated by a coal fire or an oil-burner stove is drawn through a metal tube, which takes the air up inside the chimney, where a temperature of 180 - 230 deg.C must be obtained if the fire is to burn properly. The air in the tube takes up heat from the flue gases and is brought back again into the room as warm air, supplementing the heat of the fire. The metal tube forms a conical spiral in the chimney; air is drawn into it by convection or forced in by a blower. The air passing through the spiral is always to be returned to the room it was drawn from.

Title: Mixer valve for water heating system - has spring loaded valve in by pass working in conjunction with valve in heater element circuit
Inventor: EBERT EBERHARD
IPC: F24H9/12
Filed: 1974-12-06
Abstract: The valve is used in the connection between a heating element and a single pipe hot water heating system. The housing has an inlet and outlet to the hot water connection and a common flow and return control for the heater element. The valve is hand and/or thermostat operated and diverts water from the heater circuit through the by pass connection. The system overcomes difficulties with the by pass unit. There is one spring loaded valve in the by pass at an angle of 120 deg.-135 deg. to the valve (11) that controls flow to the heater element. The two valves work together and the minimum spring force in the by pass valve (10) is determined so that it fully closes when there is slight movement of the second valve (11) due to thermostat operation.

Title: Bonding resin vulcanised rubbers to metallic load bearers - in the presence of sulphur or sulphur donors
Inventor: DROESSLER HEINZ-GUENTER DR
IPC: B32B15/06
Filed: 1975-11-27
Abstract: The bonding of rubber mixtures to metal load bearers esp. brass coated steel cables is improved. The rubber mixts. are based on natural or synthetic rubbers which are normally have fillers esp. active fillers, manipulative aids, etc. and also have vulcanisable resins, such as phenol-formaldehyde resins as vulcanising additives. Additional sulphur and/or compounds breaking down to release sulphur are mixed in with the blended rubbers. The improvement in the bonding is such that the separating limit is about the tensile limit of the separate components. This is easily recognised when a load bearer vulcanised into an assembly is torn out by force and remains of the vulcanised material are still adhering to the load bearer, or even that the metal itself is broken under the load.

Title: Eccentric press accident prevention switch - has time duration for two handed switch variable by return spring tension
Inventor: HERRMANN HERBERT
IPC: F16P3/20
Filed: 1976-04-06
Abstract: The double handed switch for accident prevention in eccentric presses incorporates two press buttons functioning with a short duration switch which cuts out after a short period. The time duration of the switch function can be adjusted and varied by modification of a return spring tension. The switching on function occurs via an inertia component, such as a silicon brake or an air cushion. This inertia is overcome slowly by a draw or torsion spring, thus causing a delay in the switching off process. The sudden release of the switch arrangement causes the circuit to be immediately broken.
Patent DE-2617972-A1 (DE)
Title: Filter clogging indicator esp. for automobiles - has guided piston and crank lever to actuate indicator slide
Inventor: HEROLD BRUNO
IPC: B01D46/42
Filed: 1976-04-24
Abstract: An indicator device for the degree of clogging of a suction air filter comprises a pot-shaped vessel with transparent indicator window and a piston acted upon by the differential pressure across the air filter, which actuates an indicator device moving across this window. The piston is biased by a compression spring towards the high pressure chamber of the pot. The piston, sealed by a flexible diaphragm to the cylinder wall of the pot actuates a cranked lever mounted on a pivot bearing offset from and perpendicular to the axis of the piston; one arm of this cranked lever is connected to the indicator device or strip, while the other arm of the lever is biased by a spring so that it always bears centrally on the piston face by a pivot bearing. Used in partic. for filter clogging indicators for mounting on the dashboard of an automobile. The piston cannot tilt sideways thus distorting the reading on the viewing face and the distance to be travelled between the at-rest position and the indicator position by the indicating device is not excessively large requiring large components. The whole apparatus is thus considerably simplified and more compact by comparison with previous designs.
