  • Patent number: 4147144
    Abstract: A disclosure describes a carburetion system for an internal combustion motor which operates wih a mixture of vapor fuel and air. The system comprises: a carburetor which is characterized by operating as a continuous injection system, and a removable heat exchanger which is incorporated into the admission system before the exhaust system, in order to heat the admission system. The carburetor is supplied under constant pressure through a pressure regulator which enables to vary the pressure of the fuel depending on the operating conditions and the behavior of the motor in general; moreover, the carburetor is provided with automatic control means to regulate the proportion of the quantities of air which accompany the formation of vapor fuel and the heat exchanger; finally, this system enables to limit the premature expansion of the combustible mixture which is introduced into the combustion chambers.

  • Patent number: 4105201
    Abstract: The disclosure describes a gymnastic balance beam which is provided with several standing or walking faces. The beam itself is in the form of an elongate body whose ends can be locked in various positions which are selected by axially rotating the body and fixing the ends. Each end of the elongated body includes a portion which has four flat faces with a bore in each face to receive a dowel which is positioned in each seat that receives the elongate body. The main walking section of the elongate body which is intermediate the ends thereof has as many different walking surfaces as there are positions which can be selected.

  • Patent number: 4085484
    Abstract: In the present invention, there is provided a pair of pressure rollers mounted on a frame for removing the excess liquid from the fabric at the nip formed between the rollers. A predetermined planar path passes through the nip of the rollers coincidental with the path of the tubular fabric, and a blade having a first flat elongated surface extends laterally of the path upstream of the squeeze rollers below and adjacent the path of the tubular fabric such that the tubular fabric is in contact with the surface. A second surface upstream of the first surface merges therewith and at an angle sloping downwardly from the first surface. A third surface downstream of the first surface merges therewith and is at an angle to the plane passing through the path of the fabric, such that the blade causes liquid and air to be drained from the tubular fabric as it passes over the first surface in contact therewith at relatively high speeds.

  • Patent number: 4068501
    Abstract: A continuous washing machine has an impregnation bath and a rinsing chamber. The rinsing chamber includes three successive sieve drums over which the tubular fabric is made to pass. The fabric passes over the second downstream sieve drum in a reverse direction so as to overturn the fabric and expose the other surface thereof and to retain the fabric over the sieve drum. A sump area is maintained in the bottom of the chamber, and the liquors from the sump are recirculated by means of spray pipes spraying rinse liquor onto the fabric. The spent rinse liquor coming from the fabric over the first sieve drum is drained out of the chamber.

  • Patent number: 4055460
    Abstract: The invention is to shake the upper run of a Fourdrinier forming fabric of a paper machine by imparting vibratory motion, in a direction transverse to the machine direction, to light-weight foil blades mounted at the dilute end of the Fourdrinier section. The foils, which are in contact with the fabric, cause the upper run to vibrate in the same transverse direction, thereby shaking the stock and improving paper formation. It is preferred to vibrate the foils at a frequency close to the resonant natural frequency of the upper run of a fabric or a harmonic thereof. All or part of the top surface of some of the foils, which contact the upper run of the forming fabric, may be coated with a material having a relatively high coefficient of friction to increase the frictional contact between the upper surface of the foil and the forming fabric.

  • Patent number: 4045202
    Abstract: This invention relates to a fusion and casting machine for the preparation of glass buttons for analysis.The machine contains an assembly of several heaters which moves with a precession motion imparting agitation to the content of the molten materials. When the materials are fused, agitation stops, flame goes out, moulds which were intially above the crucibles move under the crucibles, and the crucibles turn over and transfer their content into the moulds where solidification takes place. Perfect glass buttons are produced: these are stable, homogeneous, flat, smooth, bubble-free and need no further processing before the anaylsis.

  • Patent number: 4035872
    Abstract: The respective ends of a heavy fabric, for example, a woven dryer fabric or felt each provided with an array of connectong loops are joined with the help of a gap closing device. The gap closing device is detachably attached to the fabric when the latter is supplied to the user. When the fabric is being installed on the machine, the ends are pulled together by the gap closing device so that the arrays of loops are held in proximity and easily intermeshed to form an elongated tubular passage. A pintle wire is inserted into the passage to complete the joint. The gap closing device is then removed. A preferred gap closing device is a slide fastener, of which one tape is detachably attached to each end of the heavy fabric.

  • Patent number: 4030485
    Abstract: The invention relates to a method and apparatus for continuously monitoring systolic blood pressure of a subject. The instrument includes a light transducer for detecting variations in light intensity corresponding to variations in blood volume of tissue of the subject under the transducer and for converting the changes in light intensity to changes in voltage. In one embodiment, a heater is provided to dilate the tissue under the transducer. The voltage signals are differentiated with respect to time, and the differentiated signal is sampled once every heart beat of the subject at the beginning of diastole, or at the maximum value of the differentiated signal sampled during diastole, to produce a sampled voltage signal. To this sampled voltage signal is added a voltage representative of a steady pressure, and the sum is a voltage representative of systolic pressure.
