Abstract: A composition which forms a firm, bound aggregate-water support for floral arrangements with 60%-80% by weight water. The composition comprises a water-insoluble, water-retaining binder, such as a particulate, water-insoluble, water-swellable, cross-linked polymer, and inert non-packing, highly porous water-trapping, aggregate particles dispersed throughout, the particles being present in an amount and having a bulk density and surface area effective to disperse the composition through-out the water as the composition is added to it without hand kneading or stirring. Only sufficient binder, 0.1% to 5.0% by weight, is present to firmly bind the aggregate particles together. Rice hull ash is prefered as the aggregate and the preferred binder is acrylonitrile-starch graft copolymer. The composition can be added to water in a container of any size or shape in an amount sufficient to form the bound aggregate and the composition sinks in and disperses throughout the water and forms a support without the need for mixing with a mixer or kneading with the hands. The aggregate-water support is also used for rooting of some plants and transporting cut flowers.

Abstract: Modified inorganic polymers represented by the formula <CHEM> wherein P/ &cir&  is an inorganic polymer linked to the 3 min  or 5 min  -0- of the nucleoside through a base hydrolyzable covalent bond; R is H or a blocking group; R1 is a hydrocarbyl radical containing up to 10 carbons; each B is a nucleoside or deoxynucleoside base; and each A is H or OR. Said inorganic polymers are chemically bound to a nucleoside. The chemical bonding of the nucleoside moiety to the inorganic polymer is by means of reactive groups on the polymer which react with reactive groups of the nucleoside molecule. Such modified inorganic polymer supports are useful in the stepwise addition of nucleosides or oligonucleotides to the original nucleoside moiety of the support by a series of process steps. The starting nucleoside which is blocked in either the 3 min - or the 5 min -OH and the nucleoside is coupled through the unblocked hydroxy group to the polymer support by the coupling agent. Furthermore an automated apparatus for producing a modified silica gel which is an example of a modified inorganic polymer is shown.

Abstract: A system for recovering waste heat from a stream of heated gas is disclosed. The system includes a convection heat transfer chamber, a boiler tank, and a plurality of heat pipes thermally interconnecting the convection heat transfer chamber with the boiler tank. Each of the heat pipes includes an evaporator section which is disposed in heat transfer relation with a stream of heated gas flowing through the convection heat transfer chamber, and a condenser section disposed in heat transfer relation with a volume of water contained within the boiler tank. The boiler tank is provided with a header plate having an array of heat pipe openings through which the heat pipes project. A heat pipe support sleeve is received in each heat pipe opening in sealed engagement with the header plate, with the heat pipes projecting through the support sleeves and thermally interconnecting the convection heat transfer chamber with the boiler tank. An intermediate portion of each heat pipe is received in sealed engagement with its associated support sleeve. In a preferred embodiment, heat transfer through the support sleeve is minimized in an arrangement in which each heat pipe opening is reduced by a stepped bore with the support sleeve connected in threaded, sealed engagement with the stepped bore. Furthermore, in this arrangement, the support sleeve has swaged end portions which project beyond the header plate and engage the heat pipe on opposite sides at points which are remote with respect to the support sleeve/header plate interface. One of the swaged end portions is sealed against the heat pipe in a fluid-tight union within the boiler tank. The support sleeve is radially spaced with respect to the heat pipe, and is also radially spaced with respect to the heat pipe opening whereby heat transfer through the walls of the heat pipe to the support sleeve and to the header plate is minimized by concentric annular air gaps.

Abstract: A two-piece two-chamber self-activating dental amalgam capsule is signed to have mercury in one chamber (7) and metal powder in the other chamber (8). One section [30) of the capsule contains a chamber (15) comprising inner and outer bore portions (14b, 14c) and the other section (31) of the capsule contains the chambers (7) and (8) preferably arranged concentrically and separated oy an annular wall (9). With the capsule closed, the free end of the wall (9) fits into the inner bore portion (14b) and seals the mercury in its chamber (7), the metal powder being sealed in a mixing compartment formed by the chambers (8) and (15). In use, the capsule is shaken and the resulting force due to the inertia of the mercury opens a normally-closed valve formed by a thinner and more flexible area of the wall (9). The mercury passes into the mixing compartment and becomes triturated with the metal powder due to the shaking and forms the dental amalgam required.

Abstract: For the precision adjustment of machine tools there are used mechanical or electromechanical feeler apparatuses, for example optical indicators which are lit when contacting the surface to be machined. The precision of the adjustment by means of said apparatus does not always correspond to the precision requirements. According to the present method, the feeler approaches slowly the surface or the edge to be feeled until the contact of the feeler rotating with the surface or the edge corresponds to a rotation angle ( alpha ) of the feeler which exceeds 180<o> by a security value, but is smaller than 300<o>. The device for implementing said method comprises a casing with an electric current source and switching members for optical indicator elements. The casing is traversed by a hollow shaft connected to one pole of the current source. The hollow shaft carries at its end, on the machine side, a recording area ground with precision and, at its free end, a feeler which is electrically insulated and connected to an amplifier.
