Abstract: A movable toilet seat, the seat portion of which remains horizontal while raising and lowering. An upper frame capable of having a common toilet seat attached raises and lowers with respect to a lower frame. The lower frame provides support for the upper frame and is attached to the toilet. When the upper frame is raised, it also travels forward to allow more clearance from the toilet for the user. When the upper frame is lowered, it travels back to situate the user directly over the toilet bowl. Preferably, a reversible motor is used to raise and lower the upper frame. However, alternative embodiments encompass the use of an air shock absorber and a manual jack.

Abstract: A remotely operable exhaust blower is operatively associated with the upper discharge end of the vent pipe of a recreational vehicle holding tank. A vent line including an inlet end and an outlet end is provided with its outlet end opening downwardly into a closed passage which communicate the waste outlet of the toilet with the inlet of the holding tank. The inlet end of the vent line is communicated with the flushing water supply passage for the toilet bowl through the utilization of a float-type liquid flow preventing valve which allows downstream flow of odors and gases therethrough, prevents downstream flow of liquid under pressure therethrough and prevents upstream flow of gases therethrough in the absence of water pressure in the flushing water supply pipe upstream from the valve.

Abstract: An optical temperature sensor has an outer probe with a sapphire element at its forward end within a stagnation chamber through which hot gas flows and heats a thermally-emissive coating on the element. A lens focusses radiation emitted by the coating onto one end of a fibre-optic cable that extends within the rear of the probe. A gas passage along the probe enables cooling gas to flow from an inlet at the rear end, around the fibre optic cable, lens and through an outlet rearwardly of a transparent thermal barrier which protects the sapphire element from the cooling gas.

Abstract: Disclosed is a brake adjustment indicator which is suited for the retrofit installation on pneumatic or the like brakes systems. The indicator comprises of a plastic scratch resistant sleeve that is of three colors and fits securely over the push rod of the pneumatic actuator between the push rod attachment at the diaphragm and the clevis locking nut at the slack adjuster. The sleeve has an outside diameter permitting it to be received in the aperture of the ambient brake chamber which receives the push rod. The inside diameter of the sleeve is that of the outside diameter of the push rod. The memory of the plastic material holds the indicator on the push rod. The length of the indicator is that of the push rod between the attachment at the diaphragm and the locking nut of the clevis at the slack adjuster, with color lengths corresponding to type of application and design. When the brake is applied the sleeve travel observed outside the brake chamber is the same as that of the push rod.

Abstract: This invention relates to a novel means for detecting a low level of liquid in a reservoir. One application for the invention is to provide a way to indicate when the level of windshield washer fluid for a vehicle is at a low level. According to one of its broad aspects, the windshield washer fluid noticeable changes color on the windshield, when it is running low in the reservoir; for example, changing from very light blue to an intense red. There are known electrical and mechanical means for indicating the level of a fluid in a reservoir. However, these indicators of fluid level rely on special equipment such as floats and electrical contacts. An advantage of the present invention, is that it can be used with existing windshield washer reservoirs without the need for additional equipment and/or gauges in the interior of the vehicle.

Abstract: A household-type spa is presented which is based upon one single, major mold for manufacturing the water-containing vessel. The spa has attachment points over its walls and floor for mounting furniture such as benches and bucket seats. All furniture, regardless of type, has mounting points which correspond to those in the spa walls. Also, water and water/air jets can be directed from the spa walls outward to the person in a given seat which is spaced some distance from the spa wall, itself. The result is a spa concept which allows customers to chose a large variety of seating arrangement and jet-effect arrangements, all for a single vessel wall design.

Abstract: A calorimeter comprises a laminar flow type flowmeter for measuring the volume of flow of a fuel gas as a value proportional to the difference between the pressures of the laminar flow elements and a stream pipe serially connected to the laminar flow type flowmeter to create a laminar flow therethrough. The stream pipe is provided with a heating means, a temperature sensing means for detecting the difference between the temperatures of the fuel's flow to and from the stream pipe portion heated by the heating means, and a thermal-type flowmeter for measuring a mass flow proportional to the differential temperature sensed. A computer unit calculates the outflow pressure and the volume of flow of the fuel gas in its normal state from the measured values of the absolute pressure, the differential pressure and the temperature of the fuel gas flowing into the laminar flow-type flowmeter and calculates the calorific value of the fuel gas as a value that is negatively proportional to the differential pressure.

Abstract: Apparatus and method for determining and tracking dew point temperatures. The dew point is measured by lowering the temperature of a condensing surface that is associated with a heat flow sensor. After condensation occurs the heat flux across the condensing surface is maintained at a preselected value by adjusting the temperature of the condensing surface. As long as a positive heat flow is maintained into the condensing surface, the temperature of the condensing surface is maintained at a slightly lower temperature than the saturation temperature which is by definition the dew point. The dew point temperature calculation is based on the relationship that when condensate forms on the condensing surface, the temperature of the condensing surface approaches the dew point temperature as the heat flow rate across the condensing surface approaches zero, i.e., at adiabatic conditions.
