Abstract: A linear electric motor comprises a hollow cylindrical frame 11 of magnetizable material, an elongated armature 20 provided with a permanent magnet 21 having a pair of magnetic poles 22, 23 supported for linear axial movement in the frame, and a stationary winding 30 circumposing the armature 20, the winding comprising a pair of coils 32, 33 wound on a pair of axially spaced bobbins 42, 43 secured to the frame. The bobbins supporting the coils are disposed adjacent to respective end portions 13, 14 of the frame serving as stationary poles. Each coil circumposes a respective pole piece secured to an end of the magnet 21 and each of the coils is disposed between one of the magnetic poles and the frame. Energization of the coils of the stationary winding exerts a force on the coils with respect to the armature resulting in linear motion of the armature.

Abstract: The application of liquid to a moving fabric is effected by delivering same to a rotatable spinning disc which centrifugally impels the liquid against the fabric. This action overcomes surface tension causing the liquid droplets to break up into a fine mist so that a large area of fabric is wetted with an amount of liquid which is substantially less than the fabric weight. Also, the velocity imparted to the liquid droplets in mist forms enhances absorption of the liquid by the fabric.

Abstract: The method and apparatus may be used for copying a reference winding in order to produce a production winding similar to a reference winding. With regard to making spools of sewing thread, the production winding may have the same length of thread and winding cross-section as the reference winding. Alternatively, the main aim may be to make production windings having the same cross-section as the reference winding. According to the invention, reference data is stored in a microprocessor system whilst making the reference winding. Production data is the derived whilst making the production winding. Corresponding instantaneous values of the reference data and the production data are compared in order to derive an error signal. The error signal is supplied to an adjustable tensioner, whereby the tension of the material is adjusted, whilst making the production winding, so that a production winding is made which is similar to the reference winding. One arrangement uses a measuring wheel and a revolution counter to provide the data. Another arrangement uses a revolution counter and an arm which pivots in response to an increase in the cross-section of the winding to provide the data.

Abstract: A friction clutch driven plate for motor vehicles is of the kind in which a friction facing carrier assembly (15) is mounted for limited rotation relative to a hub (11), such limited rotation being controlled by damping springs (18A,18B,18C) and a friction damper (25,26,27,28,28A). Centrifugal control of the friction damper is by a pendulum device in the form of eccentric collars (29) pivoting on stop pins (17) and engaging apertures (33) in an intermediate plate (25) frictionally engaged with the hub. At low rotational speeds the stop pins can move within the collars which can also tilt to allow limited relative rotation between the carrier assembly (15) and the hub with low friction damping. At higher speeds the collars are effectively locked in place to give high friction damping. By suitable arrangement of windows for the damping springs this also has the effect of reducing relative rotation controlled by a low rate spring (18A) only required to damp transmission noise during engine idling.
