A filter element has a support plate (10) with a mounting groove (24) which runs round a filter chamber recess (12). A fitted filter cloth (28) which covers said recess (12) has an integrally moulded mounting frame (26) which is seated in the mounting groove (24). Thus the filter cloth can be installed on the supporting plate (10) simply, rapidly and without folds or creases, and a barrier to the ...

The outlet end (9) of a rotary drum furnace (8) for the heat treatment of free-flowing materials, in particular bulk materials, is essentially subjected to stresses which occur simultaneously and in different proportions. Various embodiments of the outlet end (9) of rotary drum furnaces (8) are therefore known from practice, where it has proved to be particularly successful to design the outlet en...

The invention relates to a curved conveyor with an endless belt, two rollers serving for its deflection, a drive means, a guide device with castors running on it, and a frame, the drive means being a toothed belt (2) fastened to the inside of the endless belt (1), the rollers (5) each being provided with a toothed ring (4) which is in engagement with the toothed belt (2), the guide device being a ...

A burner for burning pulverulent fuel with combustion air divided into concentric partial flows has a primary-air tube (6) which carries primary air or primary gas and fuel and is surrounded by a secondary-air tube (12) carrying secondary air. The primary-air tube (6) is surrounded by a flow-directing device (26) at the discharge end inside the secondary-air tube (12) while forming an annular gap ...

The coating of rotating members (1) with a reaction mixture forming polyurethane can be improved by using as the application nozzle a slot die (3) which is set at an angle alpha parallel to the axis of rotation of the member (1), and by the reaction rate of the reaction mixture and the relative movement being coordinated with the circumferential speed of the rotating member (1) in such a way tha...

Organic polymers or copolymers containing pendant, optionally protected carbonyl groups and pendant, optionally protected diol groups in the same polymer molecule or in different polymer molecules are crosslinked in the presence of acidic catalysts with formation of 1,3-dioxane or 1,3-dioxolane groups. Similar crosslinking bridges can be formed from said pendant groups with the corresponding corea...

The invention relates to a process for producing an almost water-free pressing mortar and is characterised in that finely divided substances which either decompose or irreversibly adsorb water are added to the conventional pressing mortar, but with these substances being encapsulated in such a way that they cannot react immediately with the make-up water but rather that the encapsulation only lose...

The invention relates to a connection block for high transmission rates in telecommunications and data technology. The connection block 1 consists of a plastic housing 2 and of metallic insulation piercing terminal contact elements 10 which are inserted in pairs, in at least two parallel rows, into the housing 2 and have connected contact fingers 15 forming spring contacts 16. In order to reduce t...

Method for manufacturing electrodes, in particular ECG (electrocardiogram) electrodes, in which labels (4) are bonded onto the upper side of a cyclically moved carrier material (1) in the form of a web, whereupon metal connection elements (6a, 6b) are joined to the labels (4) and, finally, individual electrodes are stamped out of the carrier material (1), in the form of a web, with the labels (4),...

The transistors used in self-commutated converters having an impressed DC intermediate circuit voltage, or other electronic switches which can be turned on and off, and also the diodes have undesired switching losses. The known circuits for reducing or avoiding the said losses manifest other disadvantages such as, in particular, situations in which the said power semiconductors are loaded with add...

A medical material of the present invention comprises a polymer or copolymer of a vinyl derivative having a polar group, said polymer or copolymer containing an antiplatelet agent. Since the antiplatelet agent can be continuously dissolved in the active concentration, the material has high anticoagulant activity and inhibition action of platelet loss due to activation of platelet.

A steel tire cord is composed of three to five strands twisted closely with minimum gaps between the strands. The steel tire cord is easy to handle in embedding the same in rubber to form a tire, free from corrosion and highly durable. A tire incorporates the steel tire cords which are bonded firmly to rubber in a belt layer. Tires thus fabricated are uniform in quality and highly durable. The ste...

A chlorine-free refrigerant comprised of bis (difluoromethyl) ether; CHF2OCHF2. The refrigerant may be used alone or in combination with other refrigerants. The bis (difluoromethyl) ether refrigerant is environmentally safe, non toxic, non flammable and has the desired physical, chemical and thermodynamic properties necessary for a refrigerant.

An instruction fetch control method is generally arranged so as to have a plurality of instruction buffers, issue an instruction read request to a memory when a part of the instruction buffers becomes in an empty state and store a fetched instruction in the instruction buffer in an empty state. A flag is provided for specifying another instruction buffer which becomes in an empty state after the i...
