Abstract: A RINGING GENERATOR TESTING ARRANGEMENT    FOR A DIGITAL TELEPHONE NETWORK    ABSTRACT OF THE DISCLOSURE A ringing generator testing arrangement for a digital telephone network is shown comprising a zero crossing detector connected to the ring lead of a line circuit under test.  The zero crossing detector gates a clock signal into a counter circuit during the negative to positive transition of the ringing generator signal positive half cycle.  The counter circuit advances until the next positive to negative transition of the ringing generator signal. At this time, the zero crossing detector cuts off the clock signal and the counter circuit transmits to a central control complex a count representing a measured interval of the ringing generator positive half cycle.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention provides a process for tanning hides for soles or insoles with ammonium titanyl sulphate.  The hides, subjected to soaking, liming, fleshing and deliming, are first treated with ammonium sulphate.  Successively, ammonium titanyl sulphate as well as citric acid or an alkali metal citrate are gradually added to the bath, while maintaining the temperature of the bath at a value not exceeding 37°C and its pH at values ranging from 1.7 to 2.5.  After each addition, the hides are treated until they have absorbed at least 90% of the soluble Ti (IV). Sodium sulphite and hexamethylenetetramine are then grad-ually added: this addition is such as to bring the final pH of the bath to 3.8-4.5 and to exhaust the bath in soluble Ti (IV).          NaHCO3 is successivley added till reaching a pH value of the bath ranging from 4.0 to 5.0, such pH being maintained for at least 2 hours.  At least one tanning treatment with a tannin, either prior to the treatment with ammonium titanyl sulphate (pretanning), or after the treatment with NaHCO3 (additional tanning) is carried out, said tanning being accomplished with a synthetic or vegetable tannin in the former case, and with a synthetic tannin in the latter case.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a method and in a slide-casting machine both for the casting of hollow precast units of concrete by means of slide-casting,  concrete mix is extruded onto a base by using one or several shaping members that form a cavity and the mix is compacted by moving the shaping members.  The outer face of the shaping members is provided with a projection or projections,  or a projection or projections are formed at the outer face of the shaping members from time to time.  The locations of the projections are changed relative the longitudinal axis of the shaping members. Thereby the shaping members produce forces compressing the mix in the surrounding mix, i.e. forces that compact the concrete.   It is possible to use shaping members in which the shape of the mantle portion can be changed so that the distances of the different points at the outer face of the shaping member from the longitudinal axis of the shaping member vary.  The shape of the mantle portion of the shaping member can be changed, for example, by displacing a moving member placed inside the mantle portion.

Abstract: DUAL VOLUTE MOLTEN METAL PUMP AND SELECTIVE                OUTLET DISCRIMINATING MEANS     ABSTRACT    This invention relates to improvements in molten metal pumps for the transfer of principally molten aluminum and zinc  from specialized molten and holding furnaces through fluidics control means downstream of the pump to control the direction of flow of molten metals at 1200° - 1600° tempera-tures.    The molten metal pump is characterized by both upper and lower dual volute pumps driven by the same shaft, each having separated intake filtering means adjacent the top and bottom of the pump unit.  Separated and extended molten metal intake means permit molten metal flow from a submerged environment through restricted peripheral ingress slots both about the top and bottom and into both top and bottom independent voluted pump impellers,  The invention permits direct use of the novel pump with aluminum metal, whose oxide impurities settle and/or zinc metal whose oxide particles float, in the molten state without pump modification.    Separate dual peripheral filter ingress zones lead into separated dual volume pumps removing hard particulates suspend-ed in the melt, illustratively; spalled fire brick refractory chunks, scraps of unmelted metal and other foreign inclusions from causing excessive wear and tear or total destruction of the interior volutes and their related impellers of the pumps.    The combination of the so-improved pump in cooperation with the divergent stream transition control provides an im-proved portable means of selectivity of one egress means out of two diverging exit channels through molten metal flow control means remote from the melt.

Abstract: MEASURING THE THICKNESS OF A NON-METALLIC    COATING ON AN ARCUATE METAL SURFACE                     ABSTRACT OF THE DISCLOSURE         Measuring the thickness of a non-metallic coating on an arcuate metal surface of an article by engaging the coating with a measuring head which carries a sensing member of a reactance monitoring means, and creating an electromagnetic field in the region of the head and in adjacent regions of the coated surface.  The reactance which is affected by the position and degree of curvature of the metal surface is then measured and produces a first signal indicative of the apparent thickness of the coating in the regions adjacent the head for a given degree of surface.  The degree of curvature of the metal surface is also monitored for the regions adjacent the head to provide a second signal indicative of the actual degree of curvature.  A correction factor which is dependent upon the second signal is then caused to influence the first signal and produce a modified signal which more accurately represents the true thickness of the part of the coating being measured.                             - i -
