Abstract: The invention concerns an arrangement for damping of valve stroke in an internal combustion engine and control of valve functions. In the arrangement damping is produced of a powerful stroke between the valve and seat, which is caused by discharge of oil, said damping being based on an increase in the oil's flow resistance. The oil's flow path diminishes when the valve approaches its closed position and the end 48 of a piston 6 situated against the valve approaches a diameter change 18A of a cylinder 18 and its play 48A. How deeply into a cylinder of smaller diameter a control screw 4S on a rocker arm advances the end 48 of piston 6 under the pressure of the valve spring can be controlled with said control screw 4S. As feed device for oil the arrangement also has an output opening 20 which is closed by a piston 4 situated against the cam of a camshaft and outlet openings 13A, 11A, 11B which are opened by the piston 6 situated against the valve. When discharge is permitted through the first outlet opening, opening of the valve is delayed and the time adjustment is set later than when discharge is permitted through the last discharge opening, since closure of the valve then occurs sooner.  In certain variants of the arrangement, it is possible by means of an open channel 16 to keep the valve's opening zone almost the same regardless of the control valve's 20D position. It is also possible to temporarily remove the valve from use. <IMAGE>

Abstract: In general, this invention concerns speech encoding and decoding used in digital radio systems and a method by which the processing capacity required can be reduced in a telecommunication system using discontinuous transmission between a transmitter and receiver. In particular, the method according to the invention is used to match two telecommunication systems using different encoding methods between the transmitter and receiver. In the method, the signals transmitted by the transmitter are made suitable for the receiver in the signal path so that in the first step, at least one information parameter comprising at least two content identifiers is formed for each data frame of the data parameters ( 101 ) received. In the next step, data corresponding to the original data is synthesized from the data parameters ( 101 ) of the received frames, after which the synthesized data is transmitted for recoding with an encoding method suitable for the receiver. In the final step, during recoding, at least some data parameters ( 107 ) of the frames are updated on the basis of at least one value of said content identifiers of the information parameter, and the frames to be transmitted to the receiver are selected from all the recoded data frames on the basis of the value of at least one other content identifier of the information parameter. In addition, the invention concerns a network element, which is arranged to implement the method described above.

Abstract: 577,820. Projecting stereoscopic images. SAVOYE, F. Jan. 29, 1942, No. 1247. Convention date, Jan. 29, 1941. [Class 97 (i)] In an installation for projecting stereoscopic images by the parallax stereogram method, the projection screen and the seats are so arranged that the mean plane in which the eyes of the spectators lie is parallel to that of the screen, so that stereoscopic vision is obtained by all the spectators. In the installation shown, the screen E and the plane S of the seats are both inclined at the same angle to the horizontal. Cylindrical projection and viewing gratings G<1>, G<2> respectively extend between discs g', g<2> mounted on axles carried by the wall and ceiling of the hall, so that the gratings may be rotated about an axis parallel to the plane of the screen, which lies within the, projection grating. The gratings are rotated by a belt c<2> driven from the motor M which also drives the projector. The right and left eye images are projected from spaced points, by means of a known arrangement of shutter and prisms, through the rotating grating G<1>, resulting in the formation on the screen of alternate strip elements of the two images, which are represented in the Figure as shaded and unshaded areas, and as they would appear viewed from the back of a translucent screen. The strips of the viewing grating G<2> may be made in known manner, wider than the interspaces, so as to allow a degree of lateral movement of the spectator's eyes without impairing the stereoscopic effect.

Abstract: 1306632 Photo-electric measurement of displacement ERNST LEITZ GmbH 12 Jan 1971 [27 Jan 1970] 1367/71 Heading G1A [Also in Division G4] In photo-electric apparatus for measuring the relative displacement of the photo-electric measuring head with respect to a diffraction grating, light of different orders of diffraction emerging from the grating, is monitored. The grating may be attached to an object the position of which is to be determined. In one arrangement, Fig. 1, light from a gallium arsenide diode 10, a lamp plus filter or a laser 57, is passed via mirror surface 12 to the phase grating 13 attached to the object. The + 1 and - 1 diffraction orders are directed to the right and left respectively and collected by part 16 of prism construction 14-16. A phase difference between the vertical and horizontal components of polarisation for the +1 order is set by the refractive index of prism 14 and the thickness of dielectric coating 14'. The beams are combined at semi-reflective surface 17 and emerge, as interference modulated phase-opposed fluxes via surfaces 18, 19, for application to polarizing beam-splitters 20, 21 and photo-cell pairs 22, 24 and 23, 25, which provide an electric rotating field when the phase displacement between the polarization directions is chosen at 90 degrees. Mirror 12 stops the 0 diffraction order. Plane parallel plate 27 is for zeroing purposes. The arrangement of the source should provide two components of equal strength or circularly polarized light to fall on grating 13. Alternatively, modulator 56 may provide alternately differently polarized light, when the polarizing beamsplitters will not be required, being replaced by means for switching in synchronism with the modulation frequency in the detector circuitry. In the arrangement of Fig. 2, a light source is, located beneath grating 13, attached to the object, and the + 1 and - 1 diffraction orders pass via prims 36, 35, provided with respective coatings for phase displacement of the polarization components for each order in opposite directions; to a beam-combining phase grating where further diffraction occurs for both + 1 and - 1 beams. The detection arrangement comprises three polarizing beam-splitters and photo-cell pans and which receive the interfering sub-beams (which include the + 3 diffraction order) develops signals in phase coincidence from 39, 40 and 41, 42 which are in opposition to that from 37, 38, providing a four-phase rotating field. Angular adjustment of prism 36 is for correction, modulation purposes. Grating 33 may also be movable and relative movement of it and 13 determined. Alternatively, the gratings may be rigidly attached one to the other or form parts of the same e.g. radial grating, Fig. 3, (not shown). An electro-optical or elasto-optical component 55 is provided in one of the diffracted beams for phase difference control. By provision of a cross-grating system and duplication of optical and detector arrangement, measurements in two co-ordinate directions are possible.

In an arrangement for determining which height zone a cloud 18, Fig. 1, falls within, a vertical beam 11 of electromagnetic radiation is emitted and a group of receiving devices at a spaced point 13 have adjacent directivities I . . . IV in the vertical plane, the directivities being wider than the width of beam 11. In the particular embodiments the radiation is visible light and may be amplitude-modulated to permit differentiation from daylight; it is mentioned that 1 cm. radio waves may be used. In a simple indicating arrangement the receiver outputs are connected to corresponding indicating lights; a " single-field " height zone causes a single light to be energized and an " over-lap " height zone causes two lights to be energized, the operator noting the height zone marked between the two lights. In Fig. 2 a logic circuit arrangement is utilized between the outputs of photo-cells I . . . IV and seven height zone indicators, e.g. 22, 24, 26; in the example illustrated photo-cells I and II produce outputs which thereby cause illumination of indicator 22 corresponding to the " over-lap " height zone 95 to 105 metres. The logic circuit of Fig. 2 may be effected as illustrated in Fig. 3 (not shown). An alternative logic circuit may be employed, Fig. 4 (not shown).
