Abstract: A gasolene fuel injector in which the valve member (24) is in the form of a plate which is attracted towards a pair of pole faces when a winding (17) is energised. The extent of movement of the valve member is limited by a non-magnetic spacer member (27) which is of annular form. In order to reduce the possibility of the valve member sticking to the spacer member the contact area between the valve member (24) and spacer member (27) is minimised by the provision of inwardly extending tongues (28), the tongues being engaged by the valve member.

Abstract: The evaluation system defines the position and amplitude of the required imbalance correction in a given correction plane, with continuous evaluation of the correction position and discontinuous evaluation of the correction amplitude.  The effect of different corrections for each correction plane on the static and dynamic residual imbalance are evaluated, to select that providing the smallest residual static imbalance, until the residual weight for each correction plane lies within given limits.  Pref. the different corrections are defined by the two detected imbalances for the next balancing stages for each correction plane.

Abstract: This invention applies the linkage connected between the interaxle yokes(16,18) of a truck and a railroad vehicle car body so as to create radially steered alignment of wheelsets(12,14) on circular curves without reference to the truck frame. Forces exchanged between the wheelsets and the car body are essentially longitudinal and no significant lateral forces are created on the truck frame or car body from the steering action. The steering linkage (34,40,46) utilizes the longitudinal component of relative motion of a point on the car body with reference to the vehicle truck to cause relative pivotal movement of the interaxle yokes thereby guiding the wheelsets to a radial alignment. Radial alignment is achieved by suitable proportioning of the links of the mechanism.

Abstract: An automatic application device 10 for dispensing an adhesive transfer tape T with the liner L removed includes a hub 14 for rotatably supporting a roll 12 of adhesive transfer tape and an application head 34 for pressing the adhesive transfer tape unwound from the roll onto a product 70 to which it is to be applied. An idler roller 36 is disposed above the application head to pull the liner away from the application head. A motor driven take-up roller 40 and corresponding nip roller 42 are provided to pull the liner along its path over said idler roller away from the application head. A brake roller 30 is provided along the path of the transfer tape between the roll and the application head to selectively stop the tape's advance. When the brake roller is released, the product to which the adhesive is applied pulls the tape underneath the application head, unwinding it from the roll. When the brake roller is stopped, the tape stops advancing and the adhesive strip carried on the liner is broken. A compensation roller 32 provides that when the head is lifted the tape is maintained in a fixed position relative to the head so that the leading edge of the adhesive on the tape liner returns to the proper position when the head is lowered.

Abstract: A method for determining the position of a shaft of a commutated direct current (DC) motor based on the current ripples contained in an armature current signal includes digitally sampling the armature current signal to generate signal values at sampling points. The signal value corresponding to a current sampling point and selected signal values corresponding to previous sampling points in a time interval containing the sampling points are compared. Either a rising or falling slope detection signal is generated if the comparison is indicative of either an increasing or decreasing tendency in the magnitudes of the signal values. The rising and falling slope detection signals are respectively indicative of rising and falling current ripple slopes. A current ripple signal is generated if rising and falling slope detection signals are generated one after the other in a given period. The shaft position is determined based on the current ripple signal count.
