Title: IC engine fuel injection control - has injection timing and quantity entirely pneumatically controlled by vacuum above inlet valve and in manifold
Inventor: HOFFMANN RUEDIGER DIPL ING
IPC: F02M69/20
Filed: 1977-09-26
Abstract: The pneumatically controlled fuel injection system is partic. for a reciprocating piston engine in a motor vehicle. The injection process is entirely controlled and powered by pneumatic parameters of the engine without mechanical or electric drive. The pressure is sensed in each inlet duct (5) immediately upstream of the inlet valve (3) of the cylinder (1), and in the manifold (4), and used in a metering unit (10) which controls the injection timing and quantity. The vacuum above the inlet valve may be sensed by a suction nozzle (7) which is so arranged that the high inlet flow velocity produces an ejector action at the nozzle.

Patent DE-2902913-A1 (DE)
Inventor: TABEL ROLF
IPC: A24C5/47
Filed: 1979-01-26
Abstract: The manufacturers of tip wrapping papers offer highly air-permeable grades of paper which, as a consequence of their high air permeability, are particularly suitable for the manufacture of ventilated filter cigarettes. Filter cigarettes manufactured with this paper exhibit unacceptably high fluctuations in respect of their degree of ventilation. The provision of the disclosed method makes it possible to manufacture filter cigarettes, on conventional or slightly modified cigarette machines, which despite the highly permeable tip wrapping paper used have a hitherto unmatched constancy in respect of their degree of ventilation. To this end, the degree of ventilation of these filter cigarettes is measured continuously, and discrepancies in the degree of ventilation as compared with a predetermined theoretical value are compensated by an increased or reduced application of glue for gluing the wrapping to the filter core or the wrapping to itself. In this arrangement, the application of glue can be regulated by continuously changing the wrapping angle of the tip wrapping paper on a conventional glue transfer roller.

Title: Core insert for mouthpiece of extrusion press - where numerous cores on welded structure are used in mfg. hollow mouldings, esp. perforated or ventilating bricks
Inventor: RANK HORST
IPC: B28B3/26
Filed: 1979-07-19
Abstract: The insert consists of a welded structure using two suspension rails each contg. a row of slots in which straps are located and welded.
