Abstract: The present invention provides an apparatus and method for the separation of solids entrained in fluid streams. The apparatus consists of a pipecross chamber which is divided into two regions (30, 32) by a perforated deflector/separator plate (20) angularly disposed within the chamber. A shear jet (22) is disposed perpendicular to the flow path and higher pressure fluid is thereby injected into the chamber to deflect and separate entrained solids. Embodiments are disclosed in which no deflector/separator plate is disposed within the chamber, separation being effected by the shear jet alone. In preferred embodiments the apparatus and method are used to protect a centrifugal pump impeller from damage by the solids. While conventional pipe joints and parts can be used, an alternate embodiment provides removable side plates and a removable deflector/separator plate for ease of installation and maintenance. Further enhancements include pipe elbow means having a jet in the direction of fluid flow through the elbow.

Abstract: In order to reduce the running noise of a diesel combustion engine expensive pump designs have in the past been proposed which were aimed at reducing the duration of fuel injection in the idling range of the internal combustion engine. By shifting the fuel injection delivery to the final part of the lift of the cam driving the piston of the fuel injection pump for idling operation by means of an injection start adjustment device in combination with an injection duration determined via the closing phase of an electrically controlled valve relieving the pump working chamber, a gentle combustion sequence can be easily obtained in idling operation, particularly on distributor-type fuel- injection pumps, without affecting the basic design of the fuel injection pump.

Abstract: Despite the use of a reflector (5) for directing the light, it is the aim in an outdoor-lighting fitting having a transparent lighting fitting housing (1) to obtain the visual outward appearance when the light source (3) is switched on in a manner adapted to the outward appearance in daytime, and to obtain in the event of a sufficiently high proportion of light directed onto a working surface as uniform as possible a distribution of brightness on the surface of the lighting fitting housing (1). This is achieved by using for the body of the reflector (5) a cloudy, translucent carrier material which is evaporated on with a partially transmitting reflective layer in the visual wavelength region. It is thus possible, in particular, for light fittings in pedestrian zones to be attractively styled and at the same time optimised in terms of lighting technology. <IMAGE>

Abstract: To improve the picture quality in a television receiver which displays the received television signal in accordance with the line interlace method, frame stores are increasingly used. The remaining system-related flicker disturbances caused by the line interlace method require different signal processing for stationary and moving frame sequences in known flicker reduction processes, in which the receiver switches from flicker-free to motion-correct 100-Hz field repetition rate even with a relatively slight movement. To reduce system-related line flicker disturbances with line interlace reproduction, the signals contained in the frame store are in each case divided by vertical filtering in the television receiver into a vertical high-frequency and low-frequency signal as determined by the position frequency, these signals are differently processed in dependence on movement and the processed high-frequency and low-frequency signals are reproduced with twice the vertical frequency in line interlace. The flicker reduction method according to the invention can be used in all television receivers in which the television signal is reproduced at twice the vertical frequency in line interlace. <IMAGE>

Abstract: A barrel assembly (2) includes a housing for attachment to a conventional driving tool (8). A barrel member (6) having a through bore is slidably attached at one end to the housing and carries a stress plate retaining pad (30) at the other end. A pre-assembled elongated headed fastener and stress plate combination (40) is inserted into the barrel assembly whereby, during driving, the head of the fastener is slidably guided by the barrel bore while the shank portion of the fastener is rigidly held by the locked stress plate assuring a perpendicular driving alignment between the fastener and the workpiece, such as a roof deck plate. Biasing means normally forces the barrel in an extended position relative to the housing and also permits the barrel and stress plate retaining pad to retract during a plate tapping sequence of the fastener to prevent thread stripping of the stress plate.
