Abstract: The device comprises a distributor with switching valves and individual circuits of hydraulic fluid under pressure and of vacuum, the switching valves permitting to connect the guiding tubes either to the circuit of fluid under pressure or to the circuit of vacuum. The guiding tube which encloses a remnant of a bar stock in which a last piece is machined is set under vacuum for retracting the feeding piston of this guiding tube toward the rear part of the device in an extension tube during the indexing of the barrel at the time of machining the last piece. This permits to supress the unproductive time normally necessary for retracting the feeding piston of the guiding tube in which a new bar stock to be machined must be introduced.

Abstract: A process for loading a lathe in which a new bar to be machined is introduced laterally into a guide-bar device in form of a tube during the machining of a last piece at the end of a preceding bar. The new bar causes the ejection of the remnant of the preceding bar by pushing against the rear of the preceding bar. A device for loading a lathe with bars to be machined comprises a guide-bar device in form of a tube having two parts which can be opened for laterally introducing a new bar to be machined into the tube. The bar in the tube is fed by a hydraulically controlled push-piston. Pressure pistons press the two parts of the tube against each other in order to ensure a fluid tight seal. Return pistons are utilized radially move the upper part of the tube at the time of loading.

Abstract: A rotary internal combustion engine includes a housing having a pair of communicating rotor chambers and a pair of parallel axis rotors provided in each chamber. The rotors each have outer gear teeth and an inner chamber having a mixer. A fuel/air mixture introduced into the inner chambers is homogenized by the mixer and the resulting fuel/air mist is introduced into the areas between the outer gear teeth. Rotation of the rotors compresses the fuel/air mist between the outer gear teeth and, following ignition at a point proximate engagement of the teeth, the expanding exhaust gases create a rotational force driving the rotors. The exhaust gases are extracted via ports in the housing position immediately before the inlets for the air/fuel mist. Alternatively, the inner chamber may be used to compress air which is then directed toward a fuel injector nozzle.

The lower piece comprises an insert for forming interlocking means.

Abstract: The device comprises a barrel which is indexed by a multi-spindle lathe at each machining operation. The barrel comprises guiding tubes for the bars to be machined which are in rotation in a fluid delivered between the guiding tube and the bar by pipes connected by tubular shafts to a fluid distributor having inlets connected to different sources of pressure. The feed of the bar is controlled exclusively by a feeding piston under the action of the pressure of the fluid delivered by extension tubes located at the rear of the guiding tubes and maintained in alignment with the latter by sliding rings which ensure the tightness between the tubes.

Abstract: A power supply for small integrated circuit devices which utilize a nominal supply voltage of 1.5 V but which are energized by a long-life lithium-iodine battery having a terminal voltage of 2.8 V. The power supply reduces the voltage to the integrated circuit to the required 1.5 V and also provides a means for delivering current peaks to a device operated by the integrated circuit, such as a stepping motor or LED display, while maintaining a relatively constant supply voltage to the integrated circuit.

Abstract: The invention discloses a razor connector for affixing a razor handle (10) to a razor head (12) having a base (16) disposed on the razor handle. A pair of opposed upstanding spaced members (20) are attached to the base between the base ends and each member has a flange (24) for engagement with a bar (40) of the razor head. The connector also has a pair of outriggers (36) attached to each end of the base (16) and one outrigger is on each side of the opposed upstanding members (20). The connector also incorporates means for biasing the base (16) in a beam-like fashion so as to increase the gap between opposed upstanding members (20) distal the base, which allows release of the connection between the flanges (24) and the bar (40). The means for biasing the base can be a second pair of upstanding members (46), which are squeezed in an inwardly direction.

Abstract: A sleeve for a safety razor having a handle with a blade-carrying head pivotably attached thereto includes a body portion generally elliptical in cross-section formed by two inwardly-curved opposing side walls joined along one pair of opposing edges by a flat top wall with an aperture between the other pair of opposing edges, further including flanges connected to the edges of the side walls adjacent the aperture and a set of tabs extending laterally from the outer surface of one of the curved side walls. In use, the sleeve is slid over the razor head and held in place by engagement of the flanges with the portion of the handle extending through the aperture. When a plurality of sleeve-bearing razors are stacked vertically atop one another such as during shipping, storage or sale, the tabs interlockingly engage the handle portion of the adjacent razor and thereby prevent premature removal of the sleeves from the razors.

Abstract: The accelerometer comprising two piezoelectric transducers. A common outer seismic mass acts on both transducers and an additional seismic mass acts only on the inner transducer. The sensitivity of the two transducers and the inertial forces acting thereof are so selected that the two transducers, under the action of an acceleration force, each deliver equal output signals. Both seismic masses are accessible for being tuned, in their assembled condition, prior to being mounted in a housing of the accelerometer. The accelerometer requires less material, is of small volume and lightweight, and is particularly suitable for being mounted in aircraft engines. It is also easy to manufacture.

Abstract: A foot control of the sewing machine can be actuated from a neutral position in two directions. In one case, a variable resistance becomes effective which produces regulating voltages within a determined range. A logic circuit with comparators produces for this voltage range a condition in which the driving motor of the sewing machine is controlled to operate with a number of turns corresponding to the voltage range. When the machine is stopped the needle is automatically positioned in its upper stop position. By repetitive actuation backward of the foot pedal the needle may be positioned in its bottom stop position and again in its upper stop position and so on. The logic treatment of the control signals from the foot control permits to transmit these signals for all required instructions through a two wire cable which is already required for the speed control.

Abstract: An electric door lock having a return means comprising a pair of locking members, a return member, rod guides, and leaf springs which eliminates the disadvantages of roller type pivot member locks. The lock is thinner to provide improved appearance. The locking members and return member may be connected to each other to ensure more reliable operation. A biasing force is applied to the locking members in the same direction as the pivotal movement of the locking members, and the engaging surface of the locking members does not apply force to the locking levers thereby making it possible to disengage the locking lever from the locking members using only a minimum of magnetic force and consuming only a small amount of electric power which can be conveniently supplied by a small DC battery.

Abstract: An ice warning system comprising a diaphragm set into vibration at one of its frequencies of resonance by a piezoelectric cell. The diaphragm is coupled thermally to a metallic plate alternately cooled and heated respectively below and above the ambient temperature by Peltier elements connected to a reversible DC current generator. A microprocessor measures any variation of the resonance frequency caused by a deposit of ice on the diaphragm during the cooling or heating periods and delivers an alarm signal if this variation of frequency reaches and/or exceeds a predetermined value. The microprocessor controls the period, intensity and direction of the current delivered by the DC current generator as a function of the ambient temperature and the temperature of the diaphragm. The ice warning system is preferably utilized in the aeronautical field for indicating the likelihood of natural ice formation on the engines and the wings of aircraft.
