Abstract: The extruded aluminum spacer frame for insertion between the light-transmitting plates of an insulating-glass pane is formed with one or more pairs of transversely extending aligned openings for admission of a gas into the space within the confines of the frame, for evacuation of a gas from such space, or for regulation of the pressure within the space. If the openings are to be sealed, a tough elastic sealing compound is introduced by way of one opening of each pair so as to form in the internal space of the frame a block which sealingly contacts the inner side of the frame all the way around both openings of the respective pair. A plug is thereupon threaded or driven into one of the openings and close to or even into the other opening in order to urge the mass of sealing compound into sealing contact with the frame around both openings as well as to be maintained in sealing contact with the adjacent material of the compound.

Abstract: Apparatus for administering known quantities of medicaments by iontophoresis while avoiding burns caused by extremes in the pH of the medicament medium during passage of an electric current is disclosed. It has been found that, as iontophoresis progresses in conventional iontophoresis systems, the electrolysis of water occurs to produce hydrogen or hydroxyl ions at the interface of the electrode and medicament medium. Since these ions are inter highly mobile. they are transported directly into the skin of patient in preference to the larger medicament ions. Thus, extreme changes in pH are experienced which result in burns due to the acidification of alkalinization of the medicament medium and passage of electric current through the skin. The present invention also avoids the production of other competing ions by employing a reactive electrode. The electrode and the medicament are chosen such that the electrode will react with the complementary ion (the ion which forms upon the dissociation of the medicament in solution) to form an insoluble material.

Abstract: The spirit of the invention is a rotary-head wet shaver with a shaving head 2 which has single or double razor blades 7 and which is arranged at the front end of a handle 1, a plurality of razor blades 7 being arranged on a common blade carrier 6, rotatable about an axis A, uniformly over the circumference of the latter. The cutting edges 8 of the razor blades 7 extend parallel to this axis A, and the blade carrier 6 together with the razor blades 7 can be rotated by means of a rotary knob 11 lying in the axis A and located on the blade carrier 6, into the respective shaving position and be locked there. To improve the handling of the shaver, it is proposed that it be possible for the rotary knob 11 to be pulled out. It is proposed, furthermore, that the blade carrier 6 be attachable on to the free end of a rotary axle 4, whilst the blade carrier 6 can additionally be equipped with a cover cap 16 and with a wire coil. This wire coil can likewise be used for all conventional razor blades and is not restricted to those blade carriers on rotary-head shavers.
