Abstract: A nozzle device includes an axially extending tubular, cylindrical outside part; and a cap threaded on the outside part at the front or discharge end of the device and having a discharge bore composed of a rearward cylindrical portion having a first diameter; a frontal cylindrical portion having a second diameter less than the first diameter; and a frustoconical portion connecting the rearward and frontal cylindrical portions with one another. An axially extending inside part is coaxially received in the outside part and has an outer wall defining, with the inner wall of the outside part, an annular space for guiding gas therethrough. The annular space is axially adjoined by the discharge bore of the cap.

Abstract: An inline macerating method and apparatus for treating pieces of meat with a liquid wherein the pieces of meat are first injected with the liquid and then drawn by suction through a duct in which the piece of meat is incised by cutting edges extending into the path of the pieces of meat as they traverse the duct. The pieces of meat then pass into a paddle massager or tumbler in which the liquid is massaged into the tissue.

Abstract: A manually operable tool, such as a hammer drill, for drilling and/or removing material in at least one of brittle material and low ductile material, has a continuously rotatable chuck (8) and a motor driven striking mechanism (1) for transmitting impulse-like blows to a tool bit (9) held in the chuck (8). The tool includes members (5) for transmitting impulse-like blows composed of superimposed axially-directed blows and torsional blows to the tool bit (9) in the chuck for forming drilling blows. Further, an adaptor can be provided for attachment to the hammer drill containing the members (5) for affording the superimposed blows.

Abstract: A tool for driving fastening elements (40) into a receiving material (U) includes a housing (1) with a throughbore (3), a channel (5) extending transversely and opening into the throughbore, and a guide (8). A driving device (2) is axially displaceable through the guide (8). The driving device (2) has an axially extending guide tube (9) in which a ram (7) is axially displaceable. Axial displacement of the driving device (2) is converted by control elements (10a, 10b) into transverse movement of a slide (6) located within the channel (5). The slide (6) cooperates with a separation device (12) in the form of a spring-loaded pawl at a magazine (11) holding the fastening elements (40). The magazine is mounted on the housing by a quick disconnect fitting.

Abstract: A massaging machine has a tank inclined to the horizontal and pressure-tight chute at the upper end for loading pieces of meat into the vessel and a chute at the lower end for discharging the massaged meat. The tank is supported by load cells on respective legs of a support and the paddles are designed, upon rotation, to urge the pieces of meat away from the discharge chute until the direction of the paddle shaft is reversed to allow discharge of the meat.

Abstract: In an arrangement for laying rail in a railroad track over which railway cars travel, the rails (1) include a lower base flange (1a) and an upper rail head (1b). A molded elastic bearing part (5) is positioned between the lower support member (4) and an upper support plate (3). The elastic part (5) has at least two elements each inclined in the same direction but at different angles to the plane of the track. Extensions of the elements have a common intersection (S) located above the rail flange (1a) on an outer side of the track. As a result, when a load is applied to the track, a circular pivoting motion of the rail takes place about the common intersection (S). Due to the circular pivoting motion the rail head (1d) moves essentially only in the vertical direction, whereby gauge widening does not occur in the rail track when railway cars travel over curved sections of the track.

Abstract: Device for supporting rails in a railroad track for rail-borne vehicles includes a support plate (3) positioned on a support bed (6) with profiled surfaces on the support plate and the support bed having upwardly extending flanks (4a, 7a, 5a, 8a) forming different angles. The flanks extend in the long direction of the railroad track. Elastic elements (9a, 9b, 9c, 9d) are disposed between the flanks (4a, 7a, 5a, 8a) of the support plate in the support bed, whereby the support plate can pivot relative to the support bed when a load (P.sub.H, P.sub.V) acts on the rails. The support plate pivots toward the center of the railroad track. As a result, the rail head (1d) of the rail attached to the support plate (3) is essentially offset vertically during the pivoting action, so that the rail gauge of the railroad track remains unchanged.

Abstract: A layer of viscous material is applied to a substrate by constricting a stream of pressurized viscous material prior to entry into a chamber wherein the constricted filament-shaped stream is acted upon by radially inwardly and forwardly oriented currents of compressed air which reduce the thickness of the stream and issue with such stream from the chamber through an orifice. The orientation of air currents in the chamber is such that the filament is not imparted a swirling movement. The flow of air issuing from the chamber through the orifice forms a hollow cone which surrounds the filament of viscous material on its way toward contact with the substrate.

Abstract: Two axially bored tappet valves 11, 12 are rotatably mounted in a mixing head housing 10. Primary fluid components A and B are supplied to the respective bores through radial passages 21, together with fluid additives C and D supplied through longitudinally displaced radial passages 22, whereby these components A, C and B, D undergo preliminary mixing in collection chambers 19, 20 defined by the bores. The pre-mixed components are then supplied to a final mixing chamber bore 13 defined in the housing, through nozzles 23, 24, from which they may be expelled by an axially reciprocable push rod 14. Prior to expulsion the valves are rotated in unison, which blocks the inlet passages 21, 22 and communicates the pressurized fluid components with respective tangential return passages 25, 26 via partial circumferential grooves 27, 28 in the valves. Such rotation also aligns recesses 29 in the valve bodies with the chamber 13 to allow the push rod to travel freely therethrough.
