Abstract: An apparatus is disclosed for the control of brake pressure in a trailer pulled by a tractor. The apparatus includes a two-circuit controllable relay valve as the trailer control valve. The first circuit is controlled by the brake valve of the tractor with the pressure from the brake apparatus of such tractor. The second circuit can be optionally-connected to a distribution valve with a pressure medium source with a specified pressure or with atmosphere. Activation of the distribution valve is controlled so that the distribution valve connects the second circuit with the pressure medium source before or at the beginning of the activation of the first circuit. With this apparatus, the brake pressure can be increased in the brake apparatus of the trailer prior to increase of the brake pressure in the brake apparatus of the tractor. The level of brake pressure increased first in the brake unit of the trailer can be regulated by a set screw acting on the trailer control valve.

Abstract: The invention relates to an arrangement for influencing, particularly blocking, a switching apparatus, preferably a remotely controlled switching apparatus, in dependence on mains condition data by means of feeding in an external voltage and a subsequent evaluating circuit with setpoint and actual-value comparison. For the purpose of feeding in the external voltage, an impulse generator for generating test pulses and an evaluating circuit is provided here which determines the peak value of the instantaneous electric power converted in the motor. This allows short circuits, inter-turn shorts and interruptions in the feedline to be detected reliably and rapidly in a motor. <IMAGE>

Abstract: The sauna heater has, in a side wall, a thin shaft (35) extending over a part of the width of the side wall. This shaft has approximately the thickness of the conventional insulation. In the area of its lower end, a fan (40) is provided. This is allocated an adjustment slide (55.1 to 55.3) which determines the cross-sections of the air inlet openings and thus the proportions of the air to be reheated (54.2) and fresh air (54.1). At the upper end (68) there is a deflection arrangement (70), which conveys the air forced up by the fan (40) into the heating arrangement. Electrically heated heat registers (81) are provided there. These are provided with aerated sheet-metal coverings, through which there flow currents of cool air diverted from the cold air current. The air heated in the heat registers and the cool air together pass through a suitably shaped flat distribution nozzle (85) directly under the ceiling of the sauna cabin and flow out slowly and equally noiselessly. <IMAGE>

Abstract: A detachable opening and closing structure for stool seat and cover, wherein a resistance mechanism is not actuated when opening the seat and cover, but turns them quickly within a predetermined range of angles and then operates slowly for closing, and an erection mechanism applicable preferably to such mechanism is provided further thereto. Accordingly, when opening the seat and cover, these can be handled lightly as in the case of normal seat and cover, and closed within a short time despite being loaded with a resistance. Shocks from the opening and closing mechanism to the stool side are relieved, thus preventing members from damage, loose work and the like. Further, it is not necessary to provide the erection mechanism separately from the opening and closing mechanism, a structure can be compact, the mechanism is detachable easily to simplify the maintenance work, and sanitary use is ensured.

Abstract: Very potent, stable, odorless, and phenol-free virucidal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses. Because of the low concentration of active ingredients, these solutions exhibit a very low toxicity, making them suitable for topical applications as antiseptics.
