Abstract: A replaceable cartridge valve assembly adapted for use in a sanitary fitting which includes a pair of discs, each disc having at least one opening or orifice therein to provide the valving function and an auxiliary valve means is disclosed. The valve assembly is made in the form of a removable cartridge and includes an arrangement of the valve stem which cooperates with an opening in the cartridge housing to provide the auxiliary valve means for throttling downstream from the at least one disc orifice of the disc valve means to provide a stepdown in pressure drop and thereby inhibit and/or reduce cavitation and other objectionable noises.

Abstract: A kiln car which permits a substantial increase of product throughput per car per day through a kiln is disclosed. The kiln car includes a carriage for conducting the car through the kiln and a superstructure made of reduced mass of dense refractory components. A lower load-bearing base is arranged and constructed so that the load-bearing surface lies in a plane below the plane of the bench of the kiln to provide an increased cross-sectional area for product firing. The low-mass, load-bearing base includes a plurality of spaced, parallel, dense, refractory blocks which are resistant to thermal shock and capable of withstanding temperatures of about 1300.degree. C., and are positioned transversely on the carriage. Each block is formed having aligned and spaced bores or sockets for mounting a column of dense refractory in each bore.

Abstract: A sanitary water valve of the disc valve type is provided with a noise damping assembly which is arranged in the recess of a disc is disclosed. The noise damping assembly is preferably in the form of a screen, is arranged and constructed to be self-retaining or self-clipping and requires no latching members for mounting the noise damping assembly with the recess of the disc.

Abstract: An apparatus for casting toilet tanks from ceramic material in slip form is disclosed. A plurality of mold parts which include two side mold parts which when assembled define a casting cavity and a core part which is positioned in the mold cavity and is spaced from the mold surfaces of the two side parts to define the front back and side walls of the toilet tank. One of the side mold parts includes an integral base for forming the bottom wall of the tank. Each side mold part arranged in a general horizontal line and are shiftable longitudinally to open and close the mold unit.

Abstract: Method for slip casting toilet bowls and as mould for casting ceramic material in slip form, including a compartment having an air impermeable wall and arranged, in the casting position of the mould, so that when the mould is filled with slip air is trapped in the compartment. The compartment is located at a region where casting is not to occur and the trapped air not only achieves this but also prevents the surface of the compartment from becoming wetted, thereby making subsequent cleaning easier. The compartment may be formed either in a plaster mould part and its surface rendered air impermeable, or in a separate part made of air impermeable material, and assembled with the plaster mould parts. The mould is particularly suitable for casting a water-closet bowl, the compartment being located at the region where the open top of the bowl is formed.

Abstract: A typical embodiment of the invention described herein discloses a prepared and packaged food delivery system that permits one attendant to serve several car ports. An electrically driven carrier for transporting a gimballed tray for money and foodstuffs has a dynamic brake that permits the carrier and tray to coast to a stop and, if desired, reverse direction after a brief delay. This feature prevents spillage. An additional feature of the invention provides advertising space illumination on the carriage with adjustable illumination time.

Abstract: A mold having an integral piece for casting a hygienic-sanitary appliance is disclosed. The mold includes a lower mold piece, at least two lateral mold pieces which are mounted on the lower mold piece to define a molding cavity for an article to be cast. An upper mold piece is mounted in position on the lateral mold pieces to close the mold cavity; the lateral and upper mold pieces being separable from the lower mold piece and the cast article to leave the latter resting on the lower mold piece. Below the cavity of the mold there is provided an annular or partially annular shaped base to support the cast article.

Abstract: The invention is directed to a non-clogging flow restrictor for use in a faucet. The flow restrictor is slotted with the sides of the narrow slots either parallel to each other or divergent from each other relative to the entrance side of the respective slot. However, the length of the slots on the entrance side is considerably longer than the length of the slots on the exiting side of the restrictor. Because of this, the invention can tolerate a substantial collection of particles at the leading or flow entry edges of the slot or slots without affecting the designed flow rate.
