Abstract: Apparatus for controlling the starting of a three-phase, salient pole, synchronous motor employs a signal representing slip frequency obtained from a power sensor connected to the motor supply. It requires no connection to the field coil or to other motor component. Since the signal can be obtained from a power sensor, the starting can be controlled from a location remote from the motor, for example at the motor control switchgear. A detector determines when the signal has decreased in frequency to a point representing a rotor speed where field excitation should be applied and it provides an output control signal. This control signal causes field excitation to be applied. In its broadest sense the apparatus may be used to indicate slip frequency remotely.

Abstract: When manufacturing components by means of injection moulding an elastomer material is injected in a plastic state into a mould 4, in which the transfer of the material to an elastic state by means of vulcanization is initiated. The material is removed from the mould 4 when it is stable with regard to its shape and substantially free from pores, and the required retention time in the mould for obtaining this result restricts the capacity of the injection moulding machine. In accordance with the invention the elastomer material is subjected to the influence of a negative pressure generated by a vacuum pump 30 while in a plastic state in an injection unit 6 by means of which the elastomer material is injected in the mould. Thereby, the required retention time in the mould 4 is substantially reduced. The injection unit may be used in conjunction with a series of moulds mounted on a turntable. <IMAGE>

Abstract: A spray device having a body member including a nozzle at one end thereof formed with an orifice and a pressure chamber formed in the other end thereof. The body member is provided with a first passage which serves to deliver sprayable liquid to the orifice under the control of an axially movable needle valve which is adapted to open and close the orifice. A second passage is formed in the body member for simultaneously directing pressurized air to the pressure chamber and to the nozzle for atomizing the sprayable liquid as it flows through the orifice. An actuator mechanism is provided in the pressure chamber and is operatively connected to one end of the needle valve for controlling flow of the pressurized air between the second passage and the pressure chamber so as to automatically maintain a closing force on the needle valve that is substantially equal to but less than the force required to open the needle valve so as to insure that after initial use of the spray device the needle valve will not open to allow the sprayable liquid to flow to the orifice until the pressurized air is at a pressure sufficient to atomize the sprayable liquid.

Abstract: The invention relates to a method and apparatus for feeding lumber, especially in connection with a four-band saw for separating and feeding side boards. The problem in four-band sawing is how to separate the boards of a pair of side boards sawed off from the sides of a log or block for further processing such as trimming. This problem is solved so that the side boards that are sawed off from the log are dropped by opening side guards and then directed the side boards by means of adjustable dropping flaps onto a transverse conveyor so that they remain on the conveyor with the cant edge focus up. The boards are then piled on top of each other and/or in a laminating fashion. The side boards are arranged, by shifting them against transient stops of the transverse conveyor, into a pile wherefrom the side boards can be suitably fed further by means of stopping members arranged in connection with the conveyor on a sloping plane. The stopping members can be adjusted into at least two different positions. In the first position the uppermost board of the pile of boards continues its movement but the rest are stopped. In the second position the next side board is released, and the rest are held back. This continues until all the boards are fed.

Abstract: The invention relates to a method and a device for signaling to a vehicle operator that a higher gear should be selected. A microprocessor (1) is connected so that it can sense the rotational speed of the engine (via 3) and the vehicle road speed (via 2). The quotient of the road speed and the engine speed is determined and is commpared with a series of predetermined quotients, one for each of the gear selector positions, and the engaged gear is thus determined. For each gear there is registered the quotient of its own gear ratio and that of the next higher gear position, the quotient being zero for the highest gear. The engine speed signal is multiplied by this gear ratio value for the gear engaged and is compared with a maximum value, and if the result exceeds the maximum value, a signal is sent to indicate that a gear change should be made. In accordance with a preferred embodiment, the fact is utilized that the generator, if the generator belts slips, will produce an engine speed value which is too low, so that the first mentioned measured quotient will not agree with the predetermined quotient. An error indication is then sent indicating the need for service.

Abstract: Aminoglycosidic antibiotic comprising a 6-0-(3''-aminoglycosyl)-2-deoxystreptamine optionally having a 4-0-(aminogycosyl) group, such as kanamycins, gentamicins, sisomicin, forms reversible complex with zinc cations by association of the zinc cations with some pairs of aminohydroxyl groups in the aminoglycoside, and the zinc-complexed amino groups are blocked from acylation. Reaction of this zinc complex with an acylation reagent having an amino-blocking acyl group brings about acylation of the non-complexed amino groups to give an N-acylated zinc complex, namely a complex of zinc cation with an N-acylated aminoglycosidic antibiotic derivative. Removal of zinc cations from N-acylated zinc complex yields a partially N-acylated aminoglycosidic antibiotic where 1- and 3''-amino groups are unprotected but all other amino groups protected with acyl group. Further reaction of this partially N-acylated product with a certain alkanoic acid or N-formyl-imidazole results in preferential acylation of 3''-amino group without 1-amino group being acylated, affording a 1-N-unprotected and other N-fully-protected derivative of the aminoglycosidic antibiotic which is valuable to be 1-N-acylated with  alpha -hydroxy- omega -aminoalkanoic acid for high-yield production of known semi-synthetic 1-N-( alpha -hydroxy- omega -aminoalkanoyl)-aminoglycosidic antibiotic.
