Granted: 1995-07-10
Abstract: Delicate webs of a motif are to be embossed in a sheet of film (1) at a predetermined motif interval by means of a rotating embossing cylinder (7). The embossing cylinder (7) rolls off on a back pressure cylinder (8) and has a recess (10) for attaching the embossing stencil (12). With each revolution of the embossing cylinder (7), a gap (14) is produced relative to the back pressure cylinder (8) during a free phase, which gap is used for a relative movement between the sheet of film (1) and the embossing stencil (12). A control device (24) produces the relative movement with an adjustable amplitude which is predetermined by the motif interval on the sheet of film (1). This relative movement allows embossing at the predetermined motif interval on the sheet of film (1) irrespective of the diameter of the embossing cylinder (7). The usable length of the embossing stencil (12) is more than 50% of the circumference of the embossing cylinder (7).

Abstract: The invention relates to a method for removing liquid from a mixture of liquid and solid matter. Said mixture is led over one or more casings by means of a conveyor belt which is pervious to liquid. In use a sub-atmospheric pressure is generated in the casings during a first period, in which said casing(s) and said conveyor belt are stationary with respect to each other, whilst at the same time a pressure is exerted on the mixture by means of rollers. During a period following on said first period a relative movement takes place between the conveyor belt and the casing(s), whilst during this period no sub-atmospheric pressure is exerted in the casings and no compressive force is exerted on the mixture by means of the rollers. <IMAGE>

Title: Flushing means for drilling tools
Inventor: LOEF STIG UNO
IPC: E21B11/02

Granted: 1995-10-10
Abstract: A flushing means for drilling tools comprises a guide member (10) carrying a drill bit (20) and being rotatably centered by the mouth of a casing tube (11) which is adapted to follow the drilling tool downhole during drilling. The drill bit (20) has a bit portion (22) that projects laterally beyond and is spaced axially in front of the casing tube (11) so as to drill a hole larger than the casing tube (11). There are external flushing grooves (70,71) on the guide member (10) adapted to lead the outflow of flushing medium and debris from the hole during drilling into the casing tube (11). At least one of these grooves (70) extends from front to rear of the guide member (10). One or more further grooves (71) are open towards said rear while ending blindly into the peri-phery of the guide member (10) spaced from its front. By re-traction of the guide member (10) its front enters the casing tube (11). That closes the blind grooves (71) and an intensi-fied flushing is thus possible via the remaining open grooves (70) that extends from front to rear of the guide member (10). The cutting front (40) of the bit portion (22) is flushed rotatively in counter flow to the rotational drilling direc-tion (8) towards the full length groove (70).

Abstract: A process for making acid-activated bleaching earth from a crude attapulgite clay. A crude is selected which is mildly acidic and contains at least about 90% attapulgite. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower production costs (no washing, filtering, or waste treatment steps) and environmental soundness (no harmful environmental waste products are produced).

Title: Integrated services digital network multimedia communications system
Inventor: ANZAI MASAKI
IPC: H04N21/434
Filed: 1991-02-04
Granted: 1996-07-02
Abstract: In a multimedia communication terminal, a CPU generates a mode identifier and subsequently a switching signal in response to a command input as well as in response to receipt of an incoming mode identifier.  Frame synchronization circuitry multiplexes an outgoing digital video signal from a video codec with the mode identifier into an outgoing composite video signal, and demultiplexes an incoming composite video signal from a distant terminal into a mode identifier and a digital video signal. In response to the switching signal, the terminal is switched from video to data communication mode by coupling a LAPB (link access procedure balanced) controller to an ISDN (integrated services digital network) interface so that the CPU can exchange computer data and/or a mode identifier with the distant terminal without frame sync.  Due to the elimination of frame sync, the terminal can access a database through the ISDN network.  The terminal is switched from data to video communication mode by coupling the LAPB controller to the interface via the frame synchronization circuitry so that the video codec exchanges composite video signals with the distant terminal.  During the video mode, the synchronization circuitry supplies an incoming data mode identifier to the CPU via the LAPB controller and the CPU supplies an outgoing data mode identifier to the synchronization circuitry via the LAPB controller.

Abstract: The invention is a method for improving quality of seismic data generated with a source (34) positioned substantially at the lower end of a drill string within a wellbore. A pilot signal is detected at the upper end of the drill string for cross-correlation with signals detected by field sensors (8, 9) positioned at the earth's surface displaced from the wellbore. Noise is reduced in the pilot signal by detecting the noise with a sensor (7) positioned to be sensitive to the noise but substantially insensitive to the acoustic signal transmitted up the drill string from the source. The frequency band within which there is high coherence between the energy in the noise signal and the pilot signal is determined. The noise signal is then amplified by a factor equal to the average ratio of the energy amplitude of the pilot signal to the noise signal within this frequency band, and this weighted noise signal is substracted from the pilot signal to reduce the noise in the pilot signal.
