Abstract: Quick-freezing of food products in liquid or paste form is achieved by mixing the food with an excess of carbon dioxide snow. A finely divided carbon dioxide snow bed is formed in situ by stirring and then there is brought into contact with the resultant bed of carbon dioxide snow particles the food product in a paste or liquid state, divided on contact with the snow, until the granules of the food product are formed. The process can be used in various apparatus and is applicable in the industrial food field and for making of products intended for home consumption.

Abstract: This apparatus comprises a device for illuminating in a permanent manner a zone in which the band travels, a television camera having a high luminous sensitivity and a low remanence controlled for exposure during constant periods of time which are short relative to the speed of travel of the band with a frequency of recurrence which is substantially equal to the speed of the band divided by the length of said zone in the direction of travel of the band. In this way, said successive images detected constitute a substantially continuous representation of the band. An electronic circuit is provided for analysing the images received by the camera.

A welding chamber is positioned at each welding position, and all of the chambers are located under a buffer vacuum enclosure. Preferably each chamber is associated with an individual vacuum pump. During the time the welding gun is operated at one position, the welded pieces are discharged and a set of pieces to be welded is placed at another position.

Abstract: In an internal combustion engine ignition system having a knock sensor to back-off the ignition advance at the onset of pre-ignition knocking in the engine, the sensor is activated only during a fraction of the power stroke of each piston and the activation is achieved by processing of the ignition triggering signal rather than by incorporation of position sensors on the drive shaft of the engine/gearbox combination. The signal-processing device includes first stage means to generate a signal which is shifted by a constant time relative to the signal which it receives, and second stage means which generates a signal which is shifted relative to the incoming signal by a time corresponding to a constant angle of rotation of the engine (to take into account engine rotation speed) and these stages define the beginning and the end of the periodic signal required for control of the vibration sensor.

Abstract: The present invention relates to internal and shaft outlet seals of a pump. On both sides of a paddle-wheel are arranged a pair of coaxial discs (22-23) and (24-25), the face of one disc being smooth and the face of the other disc having spiral grooves, one of the discs of each pair being interlocked in rotation with wheel 5, whereby the liquid between two discs is subjected to a pressure increase radially outwardly compensating at least for the pressure increase due to pumping by wheel 5.

Abstract: A method of and apparatus for regulating an electron-beam welding generator of the kind having three electrodes viz: a cathode, a Wehnelt electrode and an anode. The method is characterized by a suitable combination of two methods of regulating an electron beam welding gun. One of these methods includes varying and regulating the very high voltage while maintaining the voltage applied to the Wehnelt electrode at the potential of the cathode (operation of the "diode" kind). The other method includes holding the very high voltage constant while regulating or programming the welding current by means of the voltage to the Wehnelt electrode (operation of the "triode" kind). The variations in and regulation of the very high voltage are controlled by an induction regulator associated with a thyristorized regulator.

Abstract: A magnetic interrupter type transducer for providing an ignition signal with alternating peaks and varying progressively between the peaks. The shape of the signal is a function of the configuration of the opposed surfaces between a rotor and an adjacent pole tip of a magnetic circuit which generates the ignition signal by electromagnetic induction. The variation in volume of the air gap produced during rotation of the rotor provides the signal of the desired characteristics.
