摘要： A programmable thermostat for an air conditioning system for a predetermined volume of space is provided which includes a digital memory for storing a plurality of program times and program temperatures corresponding to the program times, a sensor for sensing the ambient temperature within the predetermined volume of space, a timer for generating the current time of day, and a controller for controlling the on/off switching of the air conditioning system in response to (1) a comparison of the current time of day with the program times stored in the digital memory to access the corresponding current control temperature stored in the digital memory and (2) comparison of the current ambient temperature sensed by the sensor with the current control temperature stored in the memory. A temperature recovery system activates and controls the air conditioning system prior to a given program time so as to bring the ambient temperature of the predetermined volume of space to the control temperature corresponding to the given program time by the given program time. The programmable thermostat includes one or more display devices which provide a visual indication when the temperature recovery program has activated and is controlling the air conditioning system. The display device may also include a graphic display for visually indicating the extent to which recovery has been effected.

摘要： A method of controlling a multistage heating system so as to minimize the energy required to bring the temperature of a predetermined volume of space to a predetermined temperature level is provided. The multistage heating system includes an energy efficient first heating mechanism and at least a less energy efficient second heating mechanism. First, a time period for the multistage heating system to bring the temperature of the predetermined volume of space to the predetermined temperature level is calculated. This calculated time period is provided into a plurality of zones, each of the plurality of zones having an associated temperature limit. The first and second heating mechanism are controlled in each of the plurality of zones according to a switching logic associated with each respective zone such that the temperature within each zone does not exceed the associated temperature limit.

摘要： A programmable thermostat is integral with an air conditioning unit and includes a remote temperature sensor. The thermostat further includes a memory 11 for storing a plurality of program times and a plurality of control temperatures corresponding to the program times. A controller of the thermostat selectively controls the on/off state of the individual air conditioning unit in response to (1) a comparison of the current time of day with the program time stored in the memory to access the corresponding current control temperature stored in the memory and (2) a comparison of the current ambient temperature sensed by the sensor and the current control temperature stored in the memory to generate a control signal for the individual air conditioning unit. The thermostat may be programmed by a hand held remote control. The thermostat may incorporate a second, built-in temperature sensor (51, Fig. 8) which is disabled when the remote sensor is plugged in.

摘要： A programmable thermostat for an air conditioning system having a heating system and a cooling system includes a sensor for sensing the ambient temperature, a timer for generating the current time of day, a memory for storing a plurality of program times, and a heating and a cooling control temperature corresponding to each program time. The memory also stores a first temperature span associated with the heating control temperatures and a second temperature span associated with the cooling control temperatures. The programmable thermostat controls the on/off state of the heating and cooling systems in response to (1) a comparison of the current time of day with the program times and (2) a comparison of the current ambient temperature with the current first and second temperature spans. These comparisons generate a switching control signal for controlling the on/off states of the heating and cooling systems. An alternation controller includes a first adjustor for adjusting the first temperature span prior to a changeover from the cooling system to the heating system. A second adjustor adjusts the second temperature span prior to the change-over from the heating system to the cooling system. Cycling of the air conditioning system between the heating system and the cooling system is thereby prevented if the heating control temperature is near the cooling control temperature.

摘要： A programmable thermostat 45 is disposed at a location remote from a window air conditioning unit 10 controlled thereby. The thermostat has a temperature sensor 35 which itself is optionally remote from the thermostat. The thermostat may be programmed by a hand held remote control. The thermostat has a controller which selectively controls the on/off state of the air conditioning unit 10 in response to (1) a comparison of the time of day with program times stored in the memory to access a corresponding control temperature stored in the memory and (2) a comparison of the ambient temperature sensed by the sensor 35 and the control temperature stored in the memory. The system may log use of the air conditioner and indicate when the filter needs changing.

摘要： HO CHOW and JOSEPH E. TESTA ASPIRATION-TYPE SPRAYER WITH IMPROVED SAFETY FEATURE In an aspiration sprayer comprising a head permanently attached to the container in which the additive material is received and rotatable between operative positions one of which seals the interior of the container and the other of which unseals said interior and enables aspiration to occur, the container is provided with a plurality of recesses facing the head and the head is provided with a positioning and locking part resiliently urged toward those recesses, location of the part in a recess positioning the head in an operative position, at least that one of the recesses corresponding to the sealing position of the head and the locking part being so cooperatively shaped as to prevent rotation of the head until the part is manually removed from the recess, another of the recesses preferably being cooperatively shaped with respect to the part so that the head can be rotated relative to the container upon the application thereto of an appreciable rotational force without having to manually remove the part from the recess.

摘要： A pulsating sprinkler incorporating a three-position trip mechanism facilitating forward/reverse rotation and continuous rotation. The trip mechanism includes a trigger for reversing direction of rotation of the sprinkler, a latch for engaging an impact arm, and a control arm for maintaining the trigger in a fixed position. The trigger, latch and control arm are joined to a common pivot on the sprinkler body. A multiple position diffuser and deflector lever is adjustable for various degrees of diffusion or deflection of a water stream. The sprinkler body is easily removed from the bushing assembly by compression of snap fingers located at a terminal end of the spring body. Further, an O-ring radially seals a space between the bushing assembly and the sprinkler body. An impact arm having two plates with separated vanes extending between the plates or an impact arm with a single plate with two downwardly projecting vanes may be used for ease in molding and increasing manufacturing efficiency.
