Abstract: ABSTRACT OF THE DISCLOSURE           A microcomputer is used in the invention for control of the ignition functions of an ignition system of an i.c. engine.  A switch in an operating handle or the like is connected via a transistor to a digital input of the computer.  This reads the status of the switch once every revolution of the engine and as long as the switch is closed the ignition is delayed at an r.p.m. above a predetermined, programmed value (e.g. 3000 r.p.m.) and the r.p.m. of the engine is restricted.  When the engine shall work the switch is opened and the ignition is normal.  The restriction is used at start in order to avoid speeding during the start procedure.  As a complement to said switch a parallel switch can be connected and operated by a brake device of the engine.  During braking the r.p.m. of the engine is thereby restricted to the same value as the r.p.m. during the start.

Abstract: AUTOMATED SIZING SYSTEM CONTROLLING                      ABSTRACT          Size formulations are supplied to slasher size boxes in an efficient manner allowing nearly unlimited variation in size formulations, minimizing the floor space of size formulation equipment, minimizing energy waste, and providing reclamation of used size.  A number of size formulation components are mixed and heated to produce a size formulation having a predetermined composition and temperature. The size formulation is circulated in a closed loop past each of the size boxes.  The amount of size in each size box is sensed by a level control, and the size formulation is withdrawn from the closed loop and supplied to a size box in response to the level sensing.  A plurality of formula stations are provided, at least one adjacent and in operative communication with each size box, and additional size formulation components are added to the size formula-tion at each size formula station, and mixed with the size formulation prior to introduction into the size box.  Heating of the size formulation is accomplished utilizing an interfacial surface generation (ISG) heat exchanger, and mixing at the formula stations is accomplished utilizing an ISG mixer.  A single mixing tank, in communication with a holding tank disposed in the closed size formulation recirculating loop, can supply all the size boxes.

Abstract: ABSTRACT                   Length Measurement Apparatus for measuring the length of a moving elongate element (1), such as a cable, comprises first and second rotative members (2), (3), rotatable by frictional contact with the element.  The second member (3) responds to changes in the velocity of the element (1) to a differing extent to that of the first member (2).  The rotation of each member is measured by detectors (11), (12), and data fed to a microprocessor (13) which compares the rotation of the two members to give an indication of the amount of slippage between one or both members and the element (1).  The slippage is taken into account in determining the length of the moving element.    The differing response to changes in velocity can be achieved by the second member (3) being of a different inertia to that of the first member (2).          Alternatively the members frictionally contact the element to a different extent.

Abstract: Abstract A power unit of the type varying its length comprises three members movable in relation to each other. The power unit is used for transferring load from a first load carrier to a second one. In order to make this transfer possible in a satisfying manner, the power unit has to be constructed so that it can be extended to at least two times its length in the contracted state. For this reason it is a necessity that trans-missions comprising wheels (13) and a loop (15) laid around these are so arranged, that  when the third member (3) is displaced with respect to the first member (1) fixed in the room, at the same time the second member (2) is displaced in the same direction and the same distance with respect to the third member (3). In order to solve this problem in an appropriate manner the invention proposes to design the first member (1) with at least partly the character of a housing for the power unit, with an elongated shape in cross section. The power device (6, 7, 8, 9, 10, 11) for displacement of the members (1, 2, 3) is disposed generally in the central region (22) of this housing. The transmissions are two in number and they are generally symmetrical in a mirror image relation to each other with respect to a plane comprising the longitudinal axis of the power device and being perpendicular to the greater dimension of the cross sectional shape of the housing (S-S plane). (Fig 1, 2 and 3).

Abstract: BUCK BOOST SWITCHING REGULATOR WITH         DUTY CYCLE LIMITING            Abstract In a buck-boost, switching regulator, separate signals are developed to control duty cycles of regulator switches.  Control exercised by a pair of feedback-determined reference signal voltages through which a ramp signal is swept at inputs of separate comparators, comparator outputs control respective switches.  A predetermined maximum voltage difference is permitted between the reference signal voltages.  The reference used to control switching of one end of the regulator inductance is limited to a minimum voltage corresponding to a minimum duty cycle greater than 0% while the other reference is used to control the other end of that inductance and is limited to a maximum voltage corresponding to a minimum duty cycle less than 100%. A current limiting feedback from one of the switches is operated in response to current in excess of a predetermined level to force the ramp signal to a level corresponding to 0% duty cycle for both switches at the same time.

Abstract: ABSTRACT In a power-up mode, the power supply of a televison receiver generates the normal operating level of an energizing voltage.  An overload detector generates a first control signal to shutdown the power supply and remove the energizing voltage when an overload condition occurs.  A control circuit periodically samples the level of the energizing voltage.  When the level is lower than normal, the control circuit generates a second control signal that maintains the power supply in the shut-down mode so as to prevent the power supply from attempting to restart. A third control signal inhibits the generation of the second control signal when an input alternating current voltage that supplies the power to the power supply suffers a voltage drop or blackout for only a short duration.
