Patent DE-2630438-A1 (DE)
Inventor: KUEPPER WILHELM
IPC: B65H67/06
Filed: 1976-07-07
Abstract: In order largely to eliminate the possibility of faults, the textile bobbins (12) are controlled, at the end of the transport track (13) of the oscillating conveyor (11), in conformity with the bobbin extraction by the bobbin conveyor (19). For this purpose, the bobbins (12) are retained by a retaining device (23), specifically so that a particular individual bobbin (12) is maintained in a stand-by position, until a transport pocket (22) of the bobbin conveyor (19) can receive the bobbin (12). To this effect, the retaining device (23) has blocking elements (24, 25, 26, 27) which are activated successively in time and which are controlled according to the conveying speed of the oscillating conveyor (11). The blocking elements (24, 25, 26, 27) are arranged one behind the other in the conveying direction, specifically so that a textile bobbin (12) is just accommodated between them. Ideally, therefore, behind the textile bobbin (12) ready for delivery there is already at least one further textile bobbin (12) which is to be delivered next. Compartments are to some extent formed between the individual blocking elements (24, 25, 26, 27), and these compartments can each receive one bobbin (12) or, if two or more bobbins (12) are to be delivered into a respective transport pocket (22) at the same time, even two or more bobbins (12). <IMAGE>

Title: Fuel injection valve for IC engine - has cylindrical lug fitting tightly in cylindrical bore below valve seat
Inventor: BOLZMANN JOERG DIPL ING
IPC: F02M61/18
Filed: 1977-02-15
Abstract: A fuel injector valve has a needle (5) working in a body (29). The needle has a conical face (7) closing on a conical valve seat in the body. A cylindrical lug (8) projects below the conical face of the needle and slides in a cylindrical bore in the base of the body. The fuel outlet nozzles (12) are drilled in this bore. The cylindrical lug (8) is a tight fit in its cylindrical bore to form a second seal to fuel flow. When the needle lifts the conical valve opens but fuel cannot flow until the needle has lifted sufficiently for the cylindrical lug to clear its bore. This prevents valve bounce due to oscillations in the fuel supply pipes upsetting the quantity of fuel delivered.

Title: Concrete mixer dust extraction - with two exhaust tubes leading to aggregate silo stand:pipe and filter
Inventor: GILLE HERBERT
IPC: B28C7/00
Filed: 1977-03-03
Abstract: Dust extraction plant for concrete mixers, e.g. for those arranged underneath concrete mixing towers, include two exhaust pipes to carry away air displaced by the filling operation. These lead to a main exhaust pipe which is also joined by a duct from the tank of the cement weigher. The displaced cement laden gases are taken to the standpipe of the aggregate silo and leave it at the top through a duct for a filter. This prevents any dust emission into the atmosphere even with the greatest sizes of mixers. The silo standpipe can absorb all air displaced by the feed of large amounts of aggregate into the mixer. The deposited cement is recovered and the ducting also acts as air intake into an empty mixer.
