Abstract: FIRE RESISTANT CONNECTIONS AND T-LIKE SEALING MEANS THEREFOR          ABSTRACT OF THE DISCLOSURE        A fire resistant connection (12) that embodies a T-like sealing means (44) and that is operable for purposes of effectuating the establishment of a fire resistant seal between mating surfaces (18, 26), and in particular mating surfaces (18, 26) of the type that commonly are found to be present in wellhead and valve equipment (10).  The subject fire resistant connection (12) includes mating seal surfaces (18, 26) and the aforementioned T-like sealing means (44).          The T-like sealing means (44) comprises a T-shaped seal ring (44), which includes a plurality of seal lips (46, 48) and a rib (50), the latter (50) being formed on the seal ring (44) so as to be located in interposed relation between a pair of adjacent seal lips (46, 48).  Each of the plurality of seal lips (46, 48) is suitably configued so as to be positionable in sealing engagement with a corresponding one of the mating sealing surfaces (18, 26), the latter (18, 26) embodying a configuration that is complementary in nature to that of the seal lip (46, 48) engaged thereby. Likewise, the rib (50) is suitably configured such that when the seal lips (46, 48) are in sealing engagement with the mating sealing surfaces (18, 26), the rib (50) is also engaged by the mating sealing surfaces (18, 26) and is locked in position thereby.

Title: Cementitious composition comprising particulate silica
Inventor: BREEN THOMAS E
IPC: C04B28/26
Filed: 1986-10-29
Granted: 1992-03-10
Abstract: ABSTRACT A cementitious composition and, by extension, an article  of  manufacture  and  a  curable  composition  of particulate or comminuted silica, an alkali-metal silicate and, optionally, an alkyl silicate and/or ester catalyst is disclosed.   The silica,  (80-75%, 80-95%, 80-92.5%), is preferably sand, either pure silica sand for a white effect, or naturally/artificially coloured for colour effects.  The alkali metal silicate, (20-25%, 20-5%, 20-7.5%), may be either sodium and/or potassium.   The alkyl silicate is preferably  ethyl  silicate  and  the  ester  catalysts  are generally  esters  of  long  chain  organic,   (preferably unsaturated aliphatic), carboxylic acids.  Ester catalysts usually employed in foundry sand moulding may also be used. The addition of an alkyl silicate and/or ester catalyst (5-15%) appear(s) to give added strength to the product over that by the alkali-metal silicate alone.   The alkali-metal and alkyl silicate combination, moreover, is useful for the prevention  of  rough  surface  texture.    The  preferred compositions shown in parentheses above for silica and alkali-metal silicate indicate the amounts used in the absence of an additive and in the presence of the alkyl silicate and/or ester catalyst(s) respectively.  The curable composition/article of manufacture is prepared by mixing an amount of 5-20% of finely ground or comminuted "flour" of silica   with   the   balance   of   the   mix   to   exclude voids, occlusions or rough surface texture. The alkali-metal silicate may be added or prepared in situ by mixing the sand with caustic alkali. After mixing all the constituents together and reaction, if any, has ceased, the mixture is then allowed to cure for several hours at temperatures up to 200°C.  to  stabilise  and  increase  the  strength  of  the composition.   Cementitious compositions of the above type have particular advantages,  as they are resistant to the acid   constituents   in  the   urban   atmosphere,   finding applications in the manufacture of building units, such as various  tiles,  paving  materials  and  special  plastering compounds.

Title: Continuous casting method and apparatus
Inventor: LORENTO DONALD P
IPC: B22D11/07
Filed: 1988-02-12
Granted: 1993-03-09
Abstract: ABSTRACT           A continuous casting apparatus has a continuous casting mold which defines a casting passage.  The walls of the mold are provided with conduits which are connected with a source of pressurized gas and open into the casting passage at locations downstream of that where the meniscus is normally established.  During withdrawal of a continuously cast strand from the mold, gas is injected into the casting passage at a pressure sufficient to force the meniscus away from the walls of the mold.  This eliminates the friction which normally exists between the mold and the meniscus so that the mold need not be oscillated during strand withdrawal.  The continuous casting apparatus accordingly does not require an oscillating mechanism for the mold.

Title: Heel molder
Inventor: BECKA MICHAEL M
IPC: A43D21/16
Filed: 1989-02-21
Granted: 1992-11-03
Abstract: ABSTRACT            A heel molder to form the heel part of a footwear upper assembly.  The heel part includes a thermally-activated material that is deformable when heated above a threshold temperature; it is non-deformable below that threshold temperature; it is non-deformable at room temperature.  The material preferentially includes a thermally-activated adhesive, that is, an adhesive that becomes tacky or sticky at or about the temperature at which the material becomes deformable.  The heel molder receives the upper assembly, forms the same at the heel region while the material is above the threshold temperature, cools the material whereby the thermally-activated material - and the upper itself and liner - takes a permanent preformed set as a laminate for later operations.  According to the present teaching, the thermally activated material or counter, the upper and the lining of the upper typically form, when cooled, a laminate that retains its geometry for subsequent operations thereon.

Granted: 1993-05-25
Abstract: ABSTRACT      A programmable controller includes a processor module and a number of input/output modules housed in a rack.  Each input/output module contains a circuit that identifies characteristics of the module to the processor module.  The circuit has a parallel input port and a parallel output port.          The outputs and inputs of the two ports are interconnected in a predefined manner according to the module characteristics.  In addition, inputs of the input port are coupled to either a positive or negative voltage source to identify other module characteristics.  By sequentially sending data to the output port and then reading data from the input port of each input/output module, the processor can identify the characteristics of the modules in the programmable controller.

Abstract: This invention relates to organopolysiloxane composi-tions and, more particularly, to such compositions that can be cured to produce pressure-sensitive adhesives.  While the hydro-silation reaction of alkenylsiloxanes with hydrosilanes in the presence of a suitable catalyst has been used to prepare potting, molding, and elastomeric products as well as materials useful for providing substrates with a release surface, the reaction has not been used to a great extent to provide pressure-sensitive adhesives.  The present invention provides pressure-sensitive adhesive composition comprising (a) a benzene soluble, resinous copolymer, (b) a diorganoalkenylsiloxy endblocked polydiorganosiloxane, (c) a diorganohydrogensiloxy endblocked polydiorganosiloxane, (d) a crosslinking agent, and (e) a hydro-silation catalyst in an amount sufficient to effect curing of the composition.  The major advantage of the present invention is that solvent need not be used to apply the composition.  This non-use of solvent results in savings of material, time, and energy, and reduction in health and safety hazards.
