Abstract: A mixture (20) of the separated soap and some of the filtrate from the filtrate vessel (14) is altered to a temperature of 10-80 deg.C before separating the soap from this mixture, and then the remaining filtrate is returned to the filtrate vessel.  A method for improving an alkali pulping process comprises supplying some of the filtrate (12) from the pulp washing step (8) to a filtrate vessel, where soap is separated from the filtrate before the latter is returned to the pulping process (2, 4). A mixture of the separated soap and some of the filtrate from the filtrate vessel is altered to a temperature of 10-80 deg.C before separating the soap from this mixture, and then the remaining filtrate is returned to the filtrate vessel. An Independent claim is also included for the apparatus used, which includes a heat exchanger (18) between the filtrate vessel and a vessel (22) for the soap/filtrate mixture, which is used to control the temperature of the mixture.

Abstract: A device for mechanically guiding components in a lock arrangement, preferably for guiding a follower unit, comprising an electrically actuable manoeuvring element (21) preferably a motor. A first engagement element (23,24) is coupled mechanically to the manoeuvring element for linear movement along a movement axis between a first and a second end position. A first arm (25) which is rotatable about a rotatable shaft (A) includes a second engagement element (27) located in mechanical engagement with the first engagement element. Because each of the first and second engagement elements (23,24,27) includes a groove (27) which extends at least partially out of parallel with the movement axis of the first engagement element, the first arm is caused to rotate when the first engagement element moves linearly. This results in a simple and flexible guide device.

Abstract: A piston ring has a wear-resistant band (38) disposed between two lands (40, 42). The piston ring is split, the division including two oppositely disposed surfaces (52, 70) which are radially and axially inclined and which terminate in one of the lands (40). This construction means that the wear-resistant band (38) terminates at axially extending edges (80, 62) but does not have exposed circumferentially extending edges, which would be prone to damage during manufacture. In one embodiment the band is nearer one edge of the ring than the other and the outer surface of the ring is barrelled assymetrically so that the widest part of the ring is in the centre of the band. <IMAGE>

Abstract: The invention relates to a time sequence control for electronically controlled breathing apparatus, using integrated circuits of sensor technology, in which breathing rate and ratio of breathing time are to be set in a calibrated manner and varied independently of one another. It essentially consists of two shift register chains, known per se, which are in each case formed by connecting together two 3-bit counters and two binary 1-of-8 decoders. The clock inputs C of the 3-bit counters of the first shift register chain are connected to a squarewave generator via a frequency divider and are acted upon by a clock signal fT/1. Various clock frequencies fT/2 are generated for the second shift register chain by variable resetting. A flip flop is connected to the output of the second shift register chain in such a manner that it is set by the first output pulse and reset by a later variable output pulse. The last output pulse resets the 3-bit counters of the second shift register chain so that a breathing time ratio can be set independently.

Abstract: A boat propeller drive unit, a so-called inboard-outboard drive unit, has a sensor which senses the trim/tilting angle of the drive unit and is designed to be connected to an electrical indicator instrument on the boat instrument panel. The sensor is a potentiometer mounted in a recess in the drive unit steering shaft. A shaft mounted in a bore in the steering shaft engages the potentiometer and is joined at its lower end to a gear, which engages a toothed segment on the helmet of the drive unit. When the drive unit is tilted, the gear is rotated by the toothed segment, and the output signal of the potentiometer varies.

Abstract: The chain drive tensioner has a piston (29) thrust by pressure in a housing (13) against the chain in the transverse direction. The piston is fixed to a central axial rod (32), around which are locking bodies (39) with an axial spring (35) working on them. This wedges them between a seat (37) in the housing and the rod. The rod is locked in the housing so that it cannot retract, but can move in the opposite direction, as the piston moves out of the housing. Thus the piston cannot move back inwards and tension is maintained when the drive stops. On restarting, the chain is at the correct tension.

Abstract: The method generates the ignition voltage at a first time point for each engine speed that corresponds at a first engine loading to a first electrode spacing whilst at a second engine loading higher than the first the ignition voltage is generated at a second time point corresponding to a second electrode spacing shorter than the first. The ignition time point is controlled over the whole loading range of the engine such that the ignition voltage level of the spark formation, which depends on engine loading and electrode spacing, fluctuates within relatively narrow limits. The voltage fluctuates by 20 per cent about a given mean.

Abstract: A reluctance motor comprises a stator having two salient poles (11, 12) and a rotor (16) also having two poles (26, 27) and being of soft magnetic material. The stator poles (11, 12) support windings (13, 14) which when being supplied with current generate a magnetic field which strives to set the rotor in a stable position of equilibrium in which the rotor and the stator poles coincide. Either or both of the stator poles (11, 12) and/or either or both of the rotor poles (26, 27) are designed so as at high flux density to cause a constriction in a part of the cross section of the flux path in order to displace the position of equilibrium and when the flux density is moderate to distribute the flux generally uniformly over the said cross section. The constriction of the flux is formed by two recesses (17-20) or the like which are symmetrically located in a pair of stator poles and rotor poles (11, 26; 12, 27), one recess (19, 20) or the like being located in the rotor pole (26, 27) at its front or rear edge, as seen in the direction of rotation, while the other recess (17, 18) or the like is located in the stator pole (11, 12) at the opposite edge.

Abstract: Each node in the network comprises a receiver permanently connected to an input in the line and a signal transmitter connected to an output in the line via a changeover switch. This switch is activated by a specific signal, and in one position directly connects the input of the line to its output. The node which commences to form a connection for the requisite type of transmission firstly connects its own transmitter to the output of the line, and at the same time breaks the line closed loop. It thus transmits signals with its own code and a destination code, which signals after having pass through the whole loop is received by the original node receiver which confirms reservation of the line. - The destination node, after having received the original signals, connects its own transmitter to the output of the line, and at the same time breaks the closed loop, so that the original node is activated to transmit signals with its own code and an original code.
