Abstract: A linkage system is provided on a bicycle for displacing a bicycle chain between chain wheels mounted on a common axis. The linkage system includes a first linkage head fixed to a support attached to the bicycle frame and a movably positionable second linkage head connected to a device for moving the chain. An articulated lever and a guide member are connected together by a pivot joint intermediate their ends with the ends of the lever and guide member being pivotally connected to the two linkage heads. The joints connecting the lever to the linkage heads permit the lever to effect a sliding movement not available to the guide member. A mechanism for deforming the linkage system is connected to the pivot which mounts the guide member on the first linkage head.

Abstract: A process for the production of urea from ammonia and carbon dioxide in an NH3:CO2 molar ratio of from 5:1 to 8:1 comprises the synthesis of a urea solution in a synthesis reactor and the decomposition of ammonium carbamate contained in the resulting urea solution in two stages in decomposers, the first stage using ammonia as the stripping agent and the second stage using carbon dioxide as the stripping agent. The synthesis and the first decomposition stage are carried out under a pressure equal or substantially equal to each other, which pressure is from 180 to 250 bars, whereas the second decomposition stage is carried out under a pressure of from 30 to 50 bars lower than the pressure used in the first decomposition stage.

Abstract: An identification element in the form of an integrated circuit, for example for identification cards and similar data carriers. The element contains a confidential code which is known only by the lawful owner of the card and is compared in the integrated circuit with a typed in code. To prevent the unauthorized use of the card, an independent circuit (1), which is isolated from the rest of the circuit, is provided in the element to detect incorrect code inputs and then render the card inoperable for a certain period of time. The off-period can be set as a function of the possible code permutations in such a way that it is practically impossible for the fraud to find out the correct code within the normal period of validity of the card. The circuit (2) can also be used to maintain the operability of the card for a predetermined period of time when the correct code has been typed in and without any further inputs. Thus the lawful owner has the possibility of typing in his code undisturbed by other persons before the actual use of the card.

Abstract: A method of making mould cores by means of a coremaking machine consists in preparing a core compound (7) with subsequent manufacturing of a compound specimen to determine the core compound hardening duration by measuring its electrical conductivity before and after its hardening. The value of its electrical conductivity is then measured by means of a measuring logical unit (29) receiving the corresponding signal from a pick-up (13), that value being determined simultaneously with the value variation range during the core compound (7) hardening process in the core box (3). When the electrical conductivity reaches the level corresponding to a hardening degree ensuring the required strength quality of the mould core, the latter is removed from the core box (3).

Abstract: Arrangements for ultrasonic sealing comprising a sealing jaw (17) which is combined with an ultrasonics source (15) and a counterjaw (8). During the sealing the parts which are to be sealed to each other are pressed together between working surfaces (18, 19) of the jaws with simultaneous activation of the ultrasonics source as a result of which the parts are welded together. In the sealing of thin material layers it is very difficult to obtain a uniform compression over the whole surface which means that the risk of burning asunder or unsatisfactory sealing increases. In accordance with the invention this is prevented with the help of supporting elements (20) which engage with two stop faces (25) located in the nodal plane of the sealing jaw (17) and on the one hand determine the minimum distance between the working surface, on the other hand orientate the flexibly suspended jaw so that the working surfaces are parallel.

Abstract: A rapid-fire automatic gun is provided with a first magazine (6a, 6b) for a lesser number of rounds, and a second magazine (7) for a greater number of rounds. These magazines include first and second round advancement members (15, 16, 17; 21, 25, 26), respectively. The first of these round advancement means are controlled by the automatic gun proper, such that a round advancement speed depending upon the firing rate of the gun prevails in the first magazine. The second round advancement means (21, 25, 26) are drivable by drive means which realize a maximum round advancement speed in the second magazine which is considerably less, for example of the order of magnitude of 100 rounds per minute, than the maximum round advancement speed in the first magazine. Transfer means transferring rounds from the second magazine to the first magazine realize gap formation in the row of rounds in the first magazine when there is a difference in the advancement speeds of the first and the second magazines, these being successively filled during and after firing.

Abstract: The device comprises a gyro rotor shaped as a spherical ball (16) and rotating about a spin axis . The ball is supported in a spherical recess (15) in a housing or seat (14) fixedly connected to the envelope (10). The transmitted or received radiation passes through central parts (23, 20) of the ball and seat. The parts for this purpose are transparent for the radiation. The parts (23, 20) of the ball and seat form an adjustable diffraction prism similar to an 'optical wedge' for the transmitted radiation so that a plane wall (44) of the ball can be set in any desired angle relative to a plane wall (45) of the seat. - The direction (L') of the radiation lobe for outgoing and/or incoming radiation energy is then determined by the refractive index for the parts of the ball and seat, where the radiation passes, possibly in combination with the diffraction produced by a lens (12) arranged in series. The refractive index is so selected that, at an angular change of the gyro rotor or ball (16), the radiation lobe (L') will undergo an equally large angular change so that it always coincides with the spun axis (03).

Abstract: The stapling machine has a support (2) for a workpiece, a driving-in part (8) contg. a magazine (9) for staples (10) and a driver (11) for delivery of staples from the magazine. The driver is movable reatively to the support against the effect of a first return component (13) from a loading position in which the object is fitted on the support to one for driving in with the magazine located on the workpiece. A circuit (17) produces a locating impulse to the electromagnetic device sufficient to provide a magnetic field to move the armature (7), driving the driving-in part from the loading position to that for driving in a staple. This impulse is, however, inadequate for moving the driver from the starting to expelling positions. A second impulse provided by the circuit gives a magnetic field which during the final phase of the driving-in stroke gives the armature sufficient energy to move the driver from the starting to the expelling positions, thus feeding a staple from the magazine and inserting it in the workpiece.
