Patent DE-3641351-A1 (DE)
Title: Chimney head
Inventor: ANFOSSY ALAIN M
IPC: F23L17/14
Filed: 1986-12-03
Abstract: In multi-leaf chimneys comprising an inner pipe and an outer casing, the inner pipe is subjected to heat expansion as a result of the heat loading. In particular, the longitudinal expansion of the inner pipe at the chimney head results in displacements of the inner pipe with respect to the outer casing. The known expansion-joint sleeves for spanning the joint between inner pipe and outer casing are very susceptible to corrosion and span the joint only to an insufficient extent, with the result that condensation can penetrate even into the interspace between inner pipe and outer casing. In order to reduce the formation of condensation and to prevent the penetration of condensation into the interspace between inner pipe and outer casing, the invention provides a covering plate, which can be positioned on the upper end of the outer casing, a guide body, which can be connected to the covering plate and encloses the inner pipe, which projects beyond the covering plate, and a covering hood which can be placed on the upper end of the inner pipe and has a peripheral extension which projects downwards and engages over the outer side of the guide body. Chimney head for a multi-leaf chimney having an inner pipe and an outer casing.

Title: Connecting rod blower with pre-scavenging for internal combustion engines
Inventor: WOLLENHAUPT HORST DIPL ING
IPC: F02B25/22
Filed: 1987-02-12
Abstract: The connecting rod blower comprises the crankcase, the lower sectoral big end and the curved connecting rod shank, and is designed so that the connecting rod divides the crank chamber into a suction side and a pressure side. Due to this division during an entire rotation of one crankshaft revolution, scavenging air is induced on the lefthand side on the downwards stroke of the piston when the crankshaft rotates anticlockwise and the scavenging air forced into the transfer ports on the righthand side, the volume from the crank chamber and the volume which is produced by the piston stroke being added together for the cylinder charge. The prescavenging is achieved in that the scavenging air from the connecting rod blower flows through a plurality of transfer ports, of which only one port is fitted with a carburettor, the ports being controlled so that scavenging air can flow in advance and in various scavenging processes into the cylinder and flushes out the exhaust gases before these come in contact with the charge flowing in somewhat later.
Patent DE-3710415-A1 (DE)
Title: Fully automatic injection moulding process and the corresponding installation for volume-reducing conditioning of toxic and radioactive powdered and nodular resins from nuclear facilities, in the form of injection-moulded parts for waste removal and disposal of packing drums to intermediate and ultimate storage facilities
Inventor: ALTMEYER EGON
IPC: B29C45/00
Filed: 1987-03-28
Abstract: The various solidification techniques all function essentially on the same principle. The radioactive wastes are stirred into a pasty mass. After a certain time, this mass hardens together with the radioactive wastes to a solid monolithic block. The hardening time ranges from one hour for plastic with an accelerator, to one month for cement, or the stirring-in occurs in the case of bitumen by means of an extruder or thin-film evaporator. However, all methods show an increase in volume of the waste matrix. The injection-moulding method for nuclear facilities is different; here, a volume-reducing fixing and compaction of radioactive, toxic powdered and nodular resins (ion-exchange resins) is employed. Finished mouldings (pellets) are produced for the disposal of waste drums as solid, non-leachable, non-swelling, flame retardant mouldings (pellets) of colour and form depending on the qualified types of container according to the different dose rates of the pellets. The employment of operating personnel of the installation exposed to radiation is reduced to a minimum, and safe handling and transport and safe... Original abstract incomplete.
Patent DE-3724811-A1 (DE)
Title: Contact arrangement for a vacuum switch
Inventor: GELLERT BERND DR
IPC: H01H33/66
Filed: 1987-07-27
Abstract: The contact arrangement for the vacuum switch has two contact pieces (1, 2) which interact along an axis (3) and have flat contact surfaces (4, 5) which are opposite one another. Current paths (12) which extend from the contact piece interior to the envelope surfaces of the contact pieces (1, 2) and into the region of the contact surfaces (4, 5) and are inclined in the same direction with respect to the axis (3) are formed in rotationally symmetrical contact carriers (10, 11) of the contact pieces (1, 2). During switching off, those current paths (12) which are inclined in the same direction with respect to the axis (3) produce an axially directed magnetic field. This contact arrangement is intended to be distinguished by high mechanical strength and low wear. This is achieved in that the current paths (12) are bounded by holes (13) which are guided through the contact carrier (11), obliquely with respect to the axis (3). In this case, the holes extend from the contact surface (5) or the end surface (9) of the contact carrier (11) to the envelope surface of the contact carrier (11). <IMAGE>

Title: Subtraction circuit in 51111 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-08-22
Abstract: The subtraction circuit according to the subject of the invention is a true subtraction circuit, because it has a main circuit (2), which is a true subtraction circuit. This main circuit (2) processes only the value 2, because this reduces the size of the main circuit (2) to a quarter. The value 1 is processed in the dual full subtractor (6). The value 5 is processed in the dual full subtractor (7). Circuit (3) is a blocking circuit, which passes on only the high potential with the lowest value of the high potentials which occur in the output area of the main circuit (2). Circuit (4) is not a one-downwards shift circuit but a one-upwards shift circuit, because no possible subtrahend with the value 1 is processed using this circuit, but a possible partial minuend with the value 1 is processed. <IMAGE>
