Patent FI-981564-A (FI)
Inventor: VERKAMA MARKKU
IPC: G06F21/00
Filed: 1998-07-07
Abstract: The invention relates to an authentication method intended for a telecommunications network, especially for an IP network. From a terminal (TE1) in the network a first message (RR) containing an authenticator and a data unit is transmitted to the network, the data unit containing information relating to the manner in which the authenticator is formed. For carrying out authentication in the network, the data unit contained in the first message is used for determining a check value, which is compared with the said authenticator. To make it unnecessary for the terminal to perform any complicated and heavy exchange of messages when attaching to the network and for still obtaining the desired security characteristics for use, such an identification unit is used in the terminal which receives as input a challenge from which a response and a key can be determined essentially in the same manner as in the subscriber identity module of a known mobile communications system, a set of authentication blocks is generated into the network, of which each contains a challenge, a response, and a key, whereby the generation is performed in the same manner as in the said mobile communication system, at least some of the challenges contained by the authentication blocks are transmitted to the terminal, one of the challenges is chosen for use at the terminal, and, based on it, a response and key for use are determined with the aid of the terminal's identification unit, in the said first message (RR) the network is notified with the aid of the said data unit of which key corresponding to which challenge was chosen, and the authenticator of the first message and the said check value are determined with the aid of the chosen key.

Title: Improved method of and means for projecting images with the effect of movement
IPC: G09F19/18
Filed: 1938-01-19
Abstract: 509,887. Optical-projection apparatus. KONIG, J. Jan. 19, 1938, No. 1764. [Class 3 (i)] [Also in Group XX] A method of projecting stationary pictures on a screen in which certain parts of the projected pictures have a flickering effect, consists in projecting two pictures from two transparencies to be superimposed to produce one picture, the part of the picture which is to flicker being provided on one of the transparencies and being projected by a flickering beam of light, while the whole picture or the part complementary to the flickering part is provided on the other transparency and is projected by a steady beam of light. A double slide H, Fig. 1, carries both transparencies. H<1> is the stationary part of the picture with the flickering parts blacked out. These parts are represented separately at H<2>. A number of such slides are contained in frames g, Fig. 2, pivoted on the circumference of a disc h on a shaft i and are normally held vertical by springs g<11>, but can be forced downwards by the impact of the lever t on the projections g<2>. Their return movement is arrested by a disc k with a rubber ring k<1>. The lever t is operated against the tension of a spring t<6> by a cam t<1> on a shaft w. This shaft also carries a disc u engaging teeth on a disc j. An annular tongue u<1> bent up from the disc engages adjacent teeth as the disc is rotated and thus feeds the disc j forward tooth by tooth. This feeding operation is intertirned with the action of the cam t<1>. As each slide is moved down for projection, a roller g<1> on the frame g moves in a guide o. During slide changing, the projecting light is obscured by a shutter s<1> operated by a lever v controlled by the cam v<3>. Two orthodox projection systems with lamps with reflectors and condensers are used and one projection lens has a prism for securing register of the two images on the screen. The means for flickering one of the beams comprises a glass disc n, Fig. 5, covered with projecting refracting elements and a similar rotating disc n<5> mounted in an annular frame driven by a chain passing over the sprocket n<3> and another on the shaft w. This device may be replaced by a rotating shutter. The apparatus is driven by an electric motor which also drives a cooling fan in the lamp house.

Title: Improvements in or relating to a method or apparatus for facing and truing abrasive articles
IPC: B24B53/053
Filed: 1948-01-22
Abstract: 637,143. Trueing. CARBORUNDUM CO. Jan. 22, 1948, No. 2030. Convention date, Aug. 1, 1946. [Class 60] A method of trueing a rotatable abrasive member 20 consists in introducing the member between the grinding-wheel 9 and the feedwheel 10 of a centreless-grinding machine and holding it against radial movement at the beginning of axial feed until its continued centring is ensured. The spindle of the member, which may be a grinding-wheel to be trued, is received in a cup chuck lined with a bonded, tungsten-carbide material. A number, say four, of these chucks is mounted on a turret 14 and each of them is provided with a shank 22 to support a spring 21 biassing the chuck away from the grinder. The turret 14 is journalled in a frame 13 arranged for adjustment with respect to the grinder and is formed with a toothed portion 35 in mesh with a free-wheel drive which is actuated by a rack 33 connected with the piston of a reciprocating air motor 32. The admission of air to the latter is controlled by a valve 31 which is opened by engagement with a lever 26. Two stops 24, 25 carried by the lever are positioned to engage the shanks of two of the chucks. In operation, an abrasive member 20 is placed in the uppermost chuck and the lever 26 is moved rearwardly to open the valve 31 and index the turret so that the member 20 is brought opposite to the side face of the grinding-wheel. Forward movement of the lever 26 now advances (a) a spring-biassed rod 38 having a tapered gear-tooth top face which engages the portion 35 ensuring that the turret has been accurately indexed ; (b) the left-hand chuck, Fig. 1, to face the member 20; and (c) the lowermost chuck to insert a previously-faced member into the grinding throat. The axial thrust imposed by the feedwheel releases the member from its chuck and traverses it through the throat. The lever is now moved rearwardly again to repeat the operation. The stop 24 is made adjustable in order that the extent of the end-facing operation may be controlled. A simplified construction employs only one axially-displaceable chuck mounted on a pivoted arm, no turret being necessary. Specification 562,851 is referred to. The Specification as open to inspection under Sect. 91 comprises also a conventional centreless grinder equipped with trueing mechanism and illustrates, in cancelled figures 10 and 11 (not shown), the simplified construction referred to above. This subject-matter does not appear in the Specification as accepted.

Abstract: 639,187. Ordnance. JANUSZEWSKI, K., and MITCHELL, S. S. C. Jan. 21, 1946, No. 2052. [Class 92 (ii)] Relates to cartridge extractor mechanism of the kind in which the arm 4 on the pivoted extractor 1 is operated, on opening the breech, by a projection 7 on a cam 2 rotatable with the breech-block A about the axis 3 of the hinge-pin of the breech-block carrier. According to the invention, the cam 2 is mounted as a strap on an eccentric sheave 5 on the carrier and is retained by a catch (not shown) during the initial opening of the breech so as to move bodily to bring its projection 7 into contact with the extractor arm 4. As the breech continues to open, the cam 2 is positively rotated by projections 10, 11 on the carrier and the retaining catch is forcibly released. The projections 10, 11 engage projections 8, 9 on the cam and the projection 7 first acts on the surface x of the extractor arm 4 to extract the cartridge case and then on the projection 14 to eject the case. The extractor may have two arms 4 each operated by a separate eccentric cam device.
