Abstract: A variable-width friction-feed paper handling apparatus includes a rotatable drive shaft and a stabilizing shaft spaced therefrom and parallel thereto. Two carriage assemblies bridge the drive shaft and stabilizing shaft and are supported thereby and are adapted for sliding movement longitudinally therealong for accommodating varying widths of paper therebetween. Each carriage assembly includes a drive roller coaxial with the drive shaft for rotation thereby and a pivoting gate which rotatably carries a pressure roller, the gate being movable between a loading position accommodating placement of paper between the carriage assemblies and a feeding position wherein the pressure roller is in parallel cooperation with the drive roller frictionally to feed paper therebetween. Over-center springs hold the gate in its two positions and leaf springs resiliently mount the pressure roller. Each carriage assembly carries paper guide device.

Abstract: The present invention concerns a lifting appliance consisting of a chassis and a vertical column resting on the chassis and having two tubes telescopically displaceable one inside the other, one of which is firmly connected to the chassis. In addition, the appliance contains arrangements which are constructed in such a way that they give rise to a mutual displacement of the tubes and consequently to a lifting or lowering movement. The invention is distinguished by the fact that the inner tube is firmly connected to the chassis. In addition, the outer tube is provided with a slit running over its entire length. A runner carrying a lifting table or the like is attached in a sliding manner to the outer slit tube. The said arrangement consists of a pull rope, one end of which is connected to the runner and runs over deflection pulleys, attached to both ends of the slit tube, to a winch fastened to the inner tube via the slit.

Abstract: A self-emptying centrifuge drum has a piston slide that controls openings in the jacket. The piston slide is fastened without play and without axial motion to the drum in the vicinity of the inner centering surface. The requisite axial motion of the slide in the vicinity of the outer centering surface is ensured by an elastically deformable area with an axial spring coefficient that is low in relation to its radial rigidity. This novel way of guiding the piston slide, prevents one-sided frictional forces in the vicinity of the centering surfaces with concomitant wear as well as irregular opening of the slide.

Abstract: The system uses a multiplexing system to receive analog signals from devices such as temp. or humidity sensors, potentiometers etc. and passing them to an A/D converter. The digital output signals are passed to a microcomputer. A second multiplexing system receives binary signals which indicate e.g. the open or closed state of contacts and connects them also to the microcomputer. - The microcomputer performs algorithmic control functions based on the received signals, using digital address output signals carried by a two wire bus. This is carried out so that digital return signals are also received. A third multiplexing system is used for a further group of potentiometers. The computing system produces both command and interrogating output signals.

Abstract: PURPOSE: To save an extra driver, e.g. a motor or a magnet, by an arrangement wherein a motor can drive a further function, e.g. ink ribbon advance, through an eccentric ring and a rotary lever and a motor for printing a selected character functions separately. CONSTITUTION: A cam 5 and an eccentric ring 12 are secured to the motor shaft 4. The roll 13 of a turnable lever 14 abuts against the eccentric ring and the pivot shaft 15 of the lever 14 is fixed similarly to a stand 2. When the motor turns, a hammer 6 is moved toward a platen 9 by means of the cam 5. The eccentric ring 12 is turned simultaneously with the cam 5. Since the eccentric ring turns the lever 14 while resisting against the action of a spring 16, a ratchet wheel 18 is turned. The rotational motion is transmitted through a coupling part 20 to an ink ribbon. According to the structure, many functions can be driven by a same motor in addition to a print hammer and an ink ribbon.

Abstract: The present invention relates to methods and to arrangements for monitoring an object which emits a rotating or oscillating beam whose angular velocity is unknown. The time points at which the beam passes a predetermined number of measuring positions are determined. An angular velocity start value is generated and a predetermined number of object position determinations (at least two independent determinations) are made on the basis of the determined time points, the measuring positions and the start value. It is determined whether or not the position determinations can be considered to be sufficiently in agreement with one another. When agreement is considered sufficient, the start value is accepted as an approximate value, this value approximating the angular velocity of the beam with an acceptable degree of accuracy. If the position determinations are not found to be sufficiently in agreement, the start value is modified and new position determinations are made. This procedure is repeated as often as is required for the position determinations to become sufficiently in agreement with one another, wherewith the start value is accepted as a approximate value of the angular velocity. Subsequent to having obtained the approximate value of the angular velocity, a final position determination of the object can be made.

Abstract: The present invention relates to a method and an arrangement for performing a paging procedure in a radio communication system comprising a radio communication network and at least a first mobile station. Upon receiving a request for establishment of a call to the first mobile station, the radio communication network initiates (201) the paging procedure. A page signal is transmitted (202) to the first mobile station. Upon detecting (203) a deficiency in the paging procedure which potentially is due to radio signals transmitted between the first mobile station and the radio communication network being subject to excessive propagation loss, an alert signal is generated (204) to the user of the first mobile station. After performing redeeming actions aming at providing more favourable conditions for radio communication, the user triggers (205) the first mobile station to transmit (206) a manual page response signal to the radio communication network.
