Title: Method of handling bars
IPC: B65G47/252
Filed: 1977-03-21
Abstract: A method of disposing a bar of rectangular cross-section includes firstly placing the bar on a first substantially cylindrical surface which is connected to a second cylindrical surface along a common generatrix. Two tangential planes along the generatrix form a dihedral angle, preferably 145 DEG . The first surface is then tilted to cause the bar to slide toward the common generatrix until it abuts against the apex of the dihedral angle. The tilt is increased until the bar either slides or tips onto the second surface. Thereafter, the bar, which rests on the second surface on one of its wider sides, is collected. An apparatus for carrying out the method includes at least two substantially cylindrical surfaces connected along a common generatrix. Two tangential planes along the generatrix form a dihedral angle, preferably 145 DEG . The cylindrical surfaces are formed on the edges of at least two rotatable members of cruciform shape.

Patent ES-480031-A1 (ES)
Title: Electromagnetic band clutch
IPC: F16D27/02
Filed: 1979-04-27
Abstract: An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member. The driven member carries the engine cooling fan. One end of a metal band is connected to the driven member, and wraps circumferentially around the driving member in the direction of rotation of the latter. An electromagnetic coil comprising windings wound circumferentially around the driving member and rotatable therewith exert an electromagnetic force on the band when current is transmitted to the coil, drawing the band into engagement with the outer circumferential surface of the driving member, to thereby engage the clutch and cause the engine cooling fan to be rotated with the driving member. Because of the wrapping effect of the band when it engages the outer circumferential surface of the driving member, the electromagnetic force necessary to actuate the clutch is multiplied as the clutch is engaged through the servo action caused by the band wrapping around the driving member. The electrical signal is transmitted to the coil through a slip ring, and is controlled by conventional engine temperature and/or pressure sensors.

Title: The production of knitted fabric on a circular knitting machine
IPC: D04B9/46
Filed: 1980-10-02
Abstract: A knitted article such as a pair of tights is knitted in two parts on a circular knitting machine, with the two parts being joined directly by the machine. During the knitting of the body area of the first part, successive pairs of hooks of a welt dial engage stitches formed on two needles adjacent to, and on opposite parts of a longitudinal cut line. After each pair of hooks have taken the stitches, the welt dial is displaced angularly relative to the needle cylinder, for a multiple of the pitch between the needles. During the initial knitting of the second part of the article in the body area, the stitches are transferred progressively from the pairs of hooks to the needles and therefore to the fabric, the wet dial being displaced angularly relative to the needle cylinder between the stitch transfer from successive pairs of hooks.

Title: Phase compensated controlled oscillator
IPC: H03B5/00
Filed: 1980-10-08
Abstract: A controlled oscillator comprises an amplifier including an active device, a filter network arranged in a feedback loop of the amplifier for providing regenerative feedback to sustain oscillation of the amplifier, and a source of control signals. Output oscillatory signals from the amplifier and output control signals from the control source are summed by a combining network to produce a resultant controlled signal, which is coupled to the filter network. Parasitic capacitances associated with output terminals of the amplifier and control source impart an unwanted phase shift to the controlled signal. A compensation signal derived from the oscillator is supplied to the combining network with a magnitude and phase to offset the unwanted phase shift, to thereby produce a phase compensated resultant controlled signal.
