Abstract: An energizing circuit for an electric motor, driving a clockwork of a timepiece, includes a stator coil coacting with one or more magnet pairs on an associated rotor whose periodic alignment with the coil induces therein a train of monitoring pulses with a frequency proportional to the motor speed. The monitoring pulses are amplified and fed back to the coil, as driving pulses, through a coincidence gate which is opened or closed under the control of a speed-sensing network including a crystal-controlled oscillator whose output wave, stepped down in a frequency divider, is a series of timing pulses fed to a pulse counter which is reset by the monitoring pulses and whose count, therefore, varies inversely with the motor speed.

Abstract: A power steering mechanism comprises distributing means for communicating fluid pressure to the compartments of a fluid motor associated with the steering linkage of the vehicle. Each distributing means comprises a ball valve member disposed in a chamber of a housing. The valve member is urged towards a first valve seat defined in a low pressure supply passage, by means of spring means, and towards a second valve seat defined in a high pressure supply passage by means of an extension of an actuating piston, said extension extending through the low pressure passage. The piston is moved by way of a sleeve disposed intermediate between the input and output members and connected thereto by means of a spline and screw arrangement. In response to a torque applied to the input member, the sleeve is allowed to move axially for displacing the piston and modifying the position of the valve member, thereby changing the value of the pressure transmitted to the associated compartment.

Abstract: A system for connecting n cigarette manufacturing machines by a cigarette container feeding apparatus to the loading mechanism of the grouping hopper of a packeting machine. Each manufacturing machine has means for filling single successive containers. Empty containers are rythmically supplied and removed, and full ones removed and supplied, by stepwise moving conveyor devices, with the aid of storage conveyor devices to compensate for output unbalances between the several machines. The speed of the packeting machine is substantially equal to the sum of the operating speed in the time unit of the n manufacturing machines and the speed of each of said n machines is equal to v/n.

Abstract: A disc brake comprising a caliper carrying a pair of friction pads and including a hydraulic fluid motor which directly applies one of said pads against a corresponding face of a disc and, by reaction through a sliding connection between the caliper and a fixed support, the other pad against the other face of the disc is disclosed. Extraction of the pad adjacent of the fluid motor is possible through a radial aperture in the caliper by moving the pad in front of a recess provided in at least one of circumferentially spaced edges of the aperture, said aperture being offset towards the fluid motor. A removable heat shield is normally inserted between the fluid motor and its adjacent pad to avoid escape of the latter and to avoid boiling of the hydraulic fluid in the fluid motor due to heating of the brake.

Abstract: A combustion chamber for, for example, an aircraft gas turbine engine, has n upstream end wall protected by a plate serving as a heat shield, the shield-plate being spaced from the dome and cooled by fluid flowing through orifices in the dome. The shield plate is itself formed with a plurality of small dimension orifices which create fluid jets of considerable velocity which serve to atomize any liquid fuel which may stream over the shield-plate and to increase turbulence.

Abstract: An hydraulic cylinder head is disclosed having a plurality of arcuate locking segments which engage a plurality of closely spaced circular grooves of approximately trapezoidal transverse cross-section in the internal wall of the cylinder and which abut the perimeter of the head to retain it in the cylinder. A truncated conical taper is provided in the internal wall of the cylinder beyond these grooves to aid in the installation of the piston packing.

Abstract: A power steering device has a distribution valve inserted between a high pressure source formed by a pump and a reservoir for creating a pressure difference in a fluid motor connected to the steering linkage, in response to application of a torque to the steering shaft of the vehicle, thereby providing assistance to operation of the steering linkage. A by-pass passage connects the high pressure output from the pump with the reservoir and the cross section of the by-pass passage is controlled as a function of the pressure difference between the chambers of the fluid motor. The means for controlling the cross section of the by-pass passage comprise a slidable piston disposed substantially transverse in the path of the fluid flow. The piston comprises grooves and lands for respectively allowing and interrupting fluid flow in the by-pass passage. The axial position of the piston is a function of the pressure difference.

Abstract: Magnesium oxide cements are formulated to contain microfiber fillers multidirectionally oriented throughout. Secondary reinforcing fillers may also be incorporated into these inorganic cements. The use of the microfiber fillers significantly increases the modulus of rupture and tensile and impact strengths of the magnesium oxide cements thus making them available for a wide range of uses including many now presently served by reinforced synthetic organic resins.
