  • Patent number: 10646079
    Abstract: A ligature resistant holder for a roll of material that is to be disposed within a wall. The holder includes a housing of which at least one side walls has an aperture with which a support assembly is associated. The support assembly includes a support member, a biasing member, a retainer and a support housing. The retainer extends through the aperture and includes portions defining a passage through the retainer. At least partially disposed within the passage of the retainer is the support member. The support member includes an actuation portion, which extends into the chamber, and a stop portion that extends radially relative to the actuation portion and engages the retainer such that axial movement of the button through the passage is limited. The biasing member is at least partially disposed within the support housing and biases the support member for movement within the chamber.

  • Patent number: 10474170
    Abstract: Embodiments include thermostatic valves for showers and tubs in which the temperature is regulated by a thermostatic motor/element. Both the flow from the valve and the temperature are controlled by a rotary stem. Hot and cold water is pre-mixed by passage through the coils of a return spring into a mixing chamber and a ceramic valve at the top of the mixing chamber controls flow of mixed water from the mixing chamber into an outlet chamber where fluctuations in the water temperature are eliminated before the water is conveyed to the shower or tub.

  • Patent number: 10292457
    Abstract: A warming rack for holding footwear includes a base and an array of support posts supported by the base. The base defines a length extending between a first end and a second end and a width between a pair of opposing side edges. The array of support posts is configured to retain multiple articles of footwear above the base. Each support posts includes a first portion extending from a proximal end in a first direction substantially perpendicular to the base to a bend line, and a second portion extending at an angle relative to the first direction from the bend line to a terminal end. The second portion is configured to retain a corresponding article of footwear in a fixed position when the second portion is received by an interior void of the footwear.

  • Patent number: 10288189
    Abstract: A pneumatic controller for connecting to a vacuum source and providing a vacuum output signal. The pneumatic controller includes a valve body defining a number of different chambers. At least two of the chambers that are separated by diaphragm and one of these chambers is maintained at vacuum pressure. In response to a pressure differential between the two chambers, the diaphragm deforms causing a valve to move from a first position, where an output port is coupled to atmospheric pressure, to a second position, where the output port is coupled to vacuum pressure. The valve is inhibited for moving between the first and second positions unless a sufficient vacuum pressure is present. Movement of the valve from the second position to the first position is also delayed until the two chambers are substantially equalized.

  • Patent number: 10052000
    Abstract: A toilet includes a bowl and a seat. The bowl includes a base and a rim. The base includes an inner surface and an outer surface. The rim includes an upper surface and an inner surface. The inner surface of the rim extends from the inner surface of the base. The seat includes a plate portion, a neck portion, a skirt portion, a first fastening tab, and a second fastening tab. The plate portion includes an inner edge and an outer edge. The neck portion extends axially from the inner edge of the plate portion. The first fastening tab extends from the neck portion and includes a first aperture having an axis configured to intersect one of the inner surface of the rim and the inner surface of the base. The second fastening tab extends from the neck portion and including a second aperture.

  • Patent number: 10030377
    Abstract: A refill and wash down assembly for a vacuum toilet. The refill and wash down assembly includes a manifold having a left side, a right side and an inlet configured to be connected to a water source, a slot defined through the manifold and extending from the left side to the right side. The manifold further includes a plurality of left side ports defined on the left side and a plurality of right side ports defined on the right side. A first array of refill tubes extends from the ports on the right side of the manifold and a second array of refill tubes extends from the ports on the left side of the manifold. Each refill tube also has a nozzle on its distal end and is of a different length different than the other refill tubes in the same array.
