Patent SE-8302343-L (SE)
Inventor: MAURANEN P
IPC: B26D1/02
Filed: 1983-04-26
Abstract: A method and apparatus for cutting a lead-in strip from a paper web in a multiple cylinder dryer section of a paper machine and for increasing the width of the lead-in strip by a so-called oblique draw. A cutting device for cutting the web is situated alongside a region of an unsupported draw of the web in the dryer section. According to the method and apparatus, a guide surface which extends in substantially parallel relationship to the plane of the web is associated with the web cutting device. A gas flow is directed over the guide surface to stabilize the run of the web during the cutting operation performed on the web by the cutting device. The gas flow is directed onto the guide surface from a nozzle opening situated adjacent to the leading edge region of the guide surface into a space between the guide surface and the web to produce an underpressure in the space which stabilizes the web run. Alternatively, two gas flows are directed from respective leading and trailing edge regions of the guide surface toward each other onto the guide surface into the space between the web and the guide surface to stabilize the web by means of an overpressure created in the space.

Date Jun. 6, 1985.Implant intended to facilitate attachment of dental prostheses against a jaw-bone (2), including an externally threaded screw-shaped member (1), intended to be attached against a threaded hole taken up in the jaw-bone (2). In difference to previously known types of implants, the screw-shaped member (1) includes a blind hole directed from the jaw-bone (2), the first portion of which is a conically tapering portion (4), which is transformed into an internally threaded hole (3). Since the conical portion (4) adjacent to the end surface of the screw-shaped member (1) preferably is arranged with a diameter smaller than the outside diameter of the end portion, and since a cover screw with a conical head which is substantially enclosed by the conical portion (4) is utilized during the osseointegration process, the jaw-bone (2) can be permitted to enclose and encapsulate this end portion of the screw-shaped member (1) during the osseointegration process. A pillar (6) can be attached against the screw-shaped member (1), at an opposed end portion supporting a conical tubular member (7), arranged to facilitate a resilient movement in relation to the pillar (6), whereby a dental prosthesis can be attached having a restricted movement in relation to the jaw-bone (2).

Abstract: Method and apparatus for separating, from a liquid flow (60), solid particles entrained in the flow. A grid screen (10) is disposed in the liquid flow and is provided with spaced-apart bars which trap the particles, there being thereby formed so-called screenings. A first, lower scraper member (40) is disposed for a reciprocal vertical movement along the screen grid and abuts, during its upward stroke, against the grid, screenings collected against the screen grid conveyed to a shoulder like portion (22) for temporary storage of the screenings. A subsequent, upper scraper member (50) conveys the screenings in a direction towards a receptacle (70). The screenings are de-watered when in position on the shoulder-like portion and, as a rule, also as a consequence of being moved in a direction towards the receptacle along a slip plate (21). The construction comprising more than one screening members reduces vertical space requirements and makes possible the individual adaptaton of the scraper members to meet prevailing functional demands.

Abstract: A three-edged tool (12) for a woodworking machine. The edges (18,19,20) of the tool are arranged with equal angular spacing about a tool body and protrude therefrom. In the surfaces (24,25,26) between the edges are recesses (27,28,29) so shaped as to retain the tool by mating engagement with a correspondingly shaped protrusion (30) provided on a tool carrier (10), and to act as a kerf in order to guide a break in case of overload of an edge (18) to the area between two recesses (27,28). Fastening means for the tool include a support part (14) provided on the tool carrier and a clamping part (15). The support part (14) carries the protrusion (30), which is shaped to engage in a recess (28) of the tool, and has a support surface (14') for supporting a clearance surface of an edge (19) which is inactive when the tool is mounted on the tool carrier. The clamping part (15) has a clamping surface (22) which is adapted to press against the clearance surface of the second inactive edge (20) of the tool.

Abstract: In order to be able properly to connect together two three-phase power systems or to be able to connect a generator to the three-phase power system, there must be synchronism. This is given when the voltages, the frequencies, the phase angle and the phase sequence of the voltages are equal. Since the frequencies always have a slight difference, a beat occurs. Thus, synchronization is in each case only possible at a certain time. The known synchronization methods and devices have the disadvantage that switching does not occur optimally at the synchronization time. The method according to the invention is based on a cyclic digital detection of the duration of the period (F0, F1) and the phase shift (P0, P1) between two square wave signals (1, 2) which have the same phase as the alternating voltages. In each cycle (8), a counter (23) counts from one to the next but one edge of one square wave signal (1), then from this edge to the next equivalent edge of the other square wave signal (2). Then counting takes place from this edge to the next but one edge of this square wave signal (2) and lastly to the next equivalent edge of one square wave signal (1). The next synchronization time is calculated by means of a program in the process computer from the stored counts. The novel method can be used for switching more accurately at the synchronization time when the switching delay times are included. <IMAGE>

Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages. The remote storage device identifies the appropriate video still frame, stores it, combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel. By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on one television channel to 30 (or 25) different remote storage devices for retransmission to home subscribers. Thus, if a home subscriber sees a given still video frame for 10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system to transmit 300 (10 secondsx30/second) different video frames to 300 other remote storage devices, thereby serving 300 concurrent users.
