Abstract: AN APPARATUS FOR INJECTION            ABSTRACT OF THE DISCLOSURE     An apparatus for injection especially for hypodermic injection by diabetics chiefly for self-treatment and in medical practices and clinics for the hyposensibilization treatment and heparinization in connection with the preparation for operations.        The apparatus comprises cm upper chamber with negative pressure which is accumulated during the manufacturing process ; it comprises further a covering lid with a central funnel for the insertion of a syringe. Said funnel is airtightly fastened to said covering lid and a cannula shaft continues spa-tially said funnel, the lower end of which has its tip extending into a suction cup, which is airtightly sealed against said upper chamber with stored under-pressure.  From inside of the rim of said suction cup through a pipe socket inside of said upper chamber next to said cannula shaft expands a valve pin with a wax seal on its upper end. If the suction cup is posi-tioned on the skin, this effects by its one elasticity a lifting of said valve pin. If the wax is broken, the air enters from the suction cup to the upper chamber and the skin will be sucked into the cannula tip.

Abstract: ABSTRACT: Apparatus for reproducing video signals with a speed which deviates from a nominal speed.          A video recorder which 19 adapted to reproduce video signals recorded on a record carrier in the form of a tape in tracks which are parallel to each other and which are inclined relative to the longitudinal axis of the record carrier with a speed which deviates from the nominal speed. The video recorder comprises tracking-error detection means for detecting the deviation of the read head from the centre of the track to be followed. The generated tracking-error signal is applied to the tape-transport control loop. For the purpose of tracking-error detection a reference-signal generator generates reference signals which form an identification for the track to be followed. For reproduction with a deviating speed these reference signals are generated in such a pattern that this pattern corresponds to the sequence of tracks which the head would scan in the case of a free uniform motion with a constant-tape transport speed which deviates from the nominal speed, so that when such a pattern is generated the tape-speed control will establish a tape-transport speed corresponding to this pattern.

Abstract: Abstract The present invention relates to exterior thermal insulation for a detached house, a row house, a small block of flats, or a similar building, and its object is to provide a supplementary insulation panel easily installed by a small team (two people). The panels are also usable as such for exterior cladding in new construction.     The fastening of the panel can be chosen freely as regards both the fastening method and, in the direction of the fastening strip, its location.     The location of the fastening strip in relation to the thermal insulation enables the unevenness of the wall to be taken into account by compression, and thus the insulation settles tightly against its base.     The same property is present in the joints between the panels.          The fastening strip comes against the wall to be insulated, the elevations fixed to the fastening strip pass through the thermal insulation, and the strip required by the installa-tion of the facade is fastened to the elevation.     The facade-fastening strip is situated in the ventilation slot, and for this reason only the elevations form cold bridges in the wall structure. The thermal insulation presses against the wall to be insulated, and at the joints between the panels the thermal insulations directly adjoin each other - thus the insulation is uninterrupted over the entire wall.

Abstract: ABSTRACT OF THE INVENTION     A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning.     The sensors comprise detectors which include an electrically conductive housing, and one wall of the housing is substantially flush with the inside wall of the tank.  Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position.  The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall.  When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus.  A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate.  When concentrate no longer covers the detector in the sidewall, the current doesn't pass, thus indicating that concentrate needs to be added to the tank.
