Filed: 1980-01-25
Abstract: The device comprises two chambers (1, 11) each comprised of a cylinder (2, 12) wherein a piston (3, 13) slides. The revolution axises of the cylinders (2, 12) and of the pistons (3, 13) of these two chambers (1, 11) are in register. The two pistons (3, 13) or the two chambers are integral and transmit their reciprocating linear motion to the motion transforming system of the engine via a rigid rod (6). The device allows to dissociate the cycle phases of internal combustion engines so as to obtain more power and a better efficiency.

Abstract: The present invention relates to the purification of polymers. 
     Purification of a polymer requires to separate the polymer from relatively low or relatively high molecular weight fractions of this polymer. Separation processes are complex and expensive and need to be simplified. 
     The process of the invention permits to obtain a high molecular weight fraction from a polar polymer, by dissolving this polymer in a solvent, mixing with the solution a cross-linking compound and separating the resulting solid cross-linked fraction from the solution; the cross-linking compound is soluble in the solvent, has at least two proton donating or proton receiving groups which are opposite the polarity of the polar polymer and is used in an amount sufficient to crosslink only the high molecular weight molecules of the polar polymer to form cross-linked high molecular weight polymer solids. The cross-linked polymer may then be dissolved and the cross-linking compound removed by precipitation.

Abstract: A multiwall, gusseted, stepped end, pinch bottom bag is disclosed which includes a sleeved valve in a corner of one end for receiving a filling spout from a product dispensing machine. The valve is completely sift-proof and is constructed without making changes in the cut shape and relationship of the various plies of the bag to accommodate the valve sleeve. The bag is made from a plurality of plies (13-19) of flexible material, such as kraft paper, which are cut and scored to permit a multiwall, gusseted, stepped end, pinch bottom bag to be formed and to further permit a valve area to be formed at one corner when the front wall (41), rear wall (21) and gusset panels (29, 37) in that region are infolded. The valve sleeve (71) which is inserted into the valve area includes a tuck-in flap (79, 81) which is sized and shaped to correspond to the pocket formed when the wall and gusset panels are folded back against the inside walls of the bag. When the bag is being assembled, the tuck-in flap (79, 81) is inserted into the pocket, aligned with the fold lines (47, 49, 51) defining the bottom and side edges of the pocket and secured therein by a suitable adhesive.

Abstract: In order also to be able to detect on rotationally symmetrical bodies superficial areas situated in the shadow of the line of vision on a television camera, the light beams reflected at the surface are firstly reflected twice at a different angle symmetrically with respect to the axis of rotation of the body, and projected at the second reflection into a plane lying perpendicular to the axis of rotation. The reflection is performed with the aid of a mirror system, which is rotationally symmetrical intrinsically and with respect to the axis of rotation of the body (2), and consists of a conical mirror (14) and a concave mirror (16) in the shape of a conical frustum. The reflecting surface (15) of the conical mirror faces the television camera (4, 5) and is more steeply inclined ( beta ) with respect to the axis of rotation of the body than ( alpha 1) the reflecting surface (17) of the concave mirror (16) in the shape of a conical frustum, which faces the rotationally symmetrical body (2). It is especially the mouth of a bottle (1) provided on the outside with a thread (3) that comes into consideration as the rotationally symmetrical body. <IMAGE>

Abstract: @ Apparatus for detecting, in advance, by a desired length of time, the imminent failure of electric output power provided by an electric power supply due to the reduction or loss of input power. The magnitude of the voltage on an energy storage reservoir capacitor is monitored for deriving a voltage signal proportional to the rate of change thereof. The rate of change voltage (Vc) is multiplied (35) by a voltage (VWT) proportional to a desired early warning time interval and this product is added to a voltage (Vm) proportional to a minimum vlaue of voltage on the capacitor, thus representing an amount of stored energy sufficient to sustain normal output power for a desired time interval. The voltage derived by the adding means is compared (38) with the voltage on the energy storage capacitor for signalling imminent power supply failure when the compared voltages are equal.

Abstract: An electric toaster having a bread carriage which is movable from a rest position to a toasting position at the beginning of a toasting cycle. When moved to the toasting position, the carriage closes a switch which energises heating means. A voltage is then supplied to a power supply unit for a control circuit containing an oscillator (0) and a counter (C). The oscillator generates a sequence of pulses whose frequency is varied to compensate for changes in the supply voltage or changes in temperature at a location in the toaster remote from the heating means or, by means of a manually operable control, to suit the degree of browness required for the toast. Pulses from the oscillator are applied to the counter. When a predetermined count is reached, the counter provides an output which causes the carriage to be released from the toasting position and returned to the rest position.
