Abstract: ABSTRACT OF THE DISCLOSURE     An improved air-bubble massage appliance having a control unit which may be placed anywhere within reach of the person in a bathtub, without danger to him, such that he can operate the appliance without getting out of the bathtub.          Known similar appliances have the control-unit connected directly to a power outlet.  As a result, the control-unit must be placed out of the reach of the person in the bathtub for safety reasons, thereby preventing adjustment of the appliance during use.         These drawbacks are overcome according to this invention by pro-viding a mains transformer producing a low-voltage, the trans-former being accommodated in a separate mains-supply unit in such a manner that the said transformer is shielded from spray.          The housing of the said mains-supply unit, enclosing the said mains transformer, is adapted to be connected, by means of a power cable, to a power outlet.  The low-voltage is adapted to be transferred, through a connecting cable, from the housing of the mains-supply unit to the control-unit housing.  The devices accommodated in the said control-unit housing are adapted to be driven by this low-voltage.  Since only this low-voltage is applied to the control-unit housing, even if the unit falls into the bath, there is no danger to the person therein.  Nor is it necessary, for safety reasons, to have the control-unit housing permanently installed.  Only the small mains-supply housing, with the transformer, must be permanently installed out of reach of the person in the bath.

Abstract: ABSTRACT OF THE DISCLOSURE        The low pressure braze bonding of members comprised of, for example, titanium and zirconium alloys is accom-plished with the use of foil-type braze alloy preforms.   The braze alloy preforms comprise a titanium-zirconium foil which has been coated on at least one side with a layer of nickel which functions as a eutectic depressant alloying agent.  Upon heating, at a temperature below the beta transus of titanium, a liquid phase will form and the nickel will partially alloy with and migrate into the foil and workpieces and solidification of the resulting joint may thereafter be obtained.

Abstract: ABSTRACT      Conventional Boots, Shoes and Slippers come in many de-signs, shapes and sizes, and are made of a considerable var-iety of leathers, rubber, and synthetic materials.  Too often the footware does not fit the wearer properly, being too nar-row, rigid, not conforming properly to the shape of the wear-ers foot, resulting in discomfort to the wearer.      By literally allowing the wearer to walk on air, I feel that the problem of individual weight, gait, length of step and style of walking would be taken care of.     Since air is a good insulator, a shoe having an air space between the liner and the sole would be cooler in summer, warm-er in winter, absorb the shock of the impact of the wearers footsteps, be more resistant to dampness, especially in beach footwear.  An Air-sole would be a boon to people who walk on hot pavements, workshop and super market floors.
