摘要： A fluid dispenser can include a body defining a passageway from an inlet to an outlet, a fluid container configured be received by the body such that the fluid in fluid communication with the inlet, and a contactless valve in fluid communication with the outlet and configured to selectively dispense fluid from the fluid container. A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor.

摘要： A heavy duty contactor mechanism for refrigeration compressor motors is directly actuated by a timing mechanism controlled by a thermostat. The timing mechanism protects against false starts from thermostat vibration, and interposes a delay between stopping and starting of the compressor sufficient to allow pressures to equalize. Power for operating the contactor switches is stored in a spring while the timer motor is running through the delay period.

摘要： A fast operate-fast release direct current solenoid includes a main winding and an auxiliary winding having equal turns. The windings are connected in parallel to a control switch. A capacitor is connected in series with the auxiliary winding only and a diode is interposed between the control switch and both windings. When the control switch is closed, both windings are energized, causing fast pull in. The capacitor then charges and stops current to the auxiliary winding. When the control switch opens, the capacitor discharges through both coils.

摘要： Protection against refrigeration compressor burnout by short cycling is provided by a time delay switching mechanism having a motor and a solenoid controlled by a room thermostat. The motor runs continuously and the solenoid stops and starts the timer by stalling or releasing the timer gear. The timer gear has teeth omitted at the stalling points to allow the motor to run free. A starter cam follower bearing on a starter cam serves to start the timer gear when released by the solenoid. The solenoid operates the stalling and switch control mechanism through a compound leverage and camming system compensating for the non-linear pull curve of the solenoid. The device also includes a combination cam and latch operated switch in which one switch blade carries a follower lifting another blade which is then held by the latch when the follower drops to close the switch. A manual operator is provided for closing the switch independently of the timing mechanism. This manual operator is released automatically by the solenoid dropping out when the thermostat becomes satisfied. The timer also includes an arrangement for locking the compressor switch closed for a period of time when it first closes to allow the system to settle down and thus avoid short cycling.

摘要： Protection against refrigeration compressor burnout by short cycling is provided by a delay timing mechanism having a motor and solenoid. The motor is constantly energized and the solenoid controlled by a thermostat stalls or releases the mechanism causing timer operation through its cycle. The timer runs through its delay period during the normal off period, allowing fast restart of the compressor. Also the timer provides a longer delay following a short cycle then following a normal cycle. This is accomplished by operating the timer for a period of time after the compressor is started.

The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor. The controller can be configured to switch the presence sensor into the activated state in response to the detection of the prerequisite condition by the activation sensor, and to control the actuator to move the plug from the closed position to the open position in response to the detection of the object in the upper detection zone by the presence sensor.

摘要： An adjustable automatic reset pushbutton timer in which a knob is rotated to set the timing and is pushed to start the time cycles. The knob shaft carries a spring return timing cam and an adjustable stop which sets the starting point. At the end of the cycle a lobe on the cam raises a pair of switch blades with the contacts closed and then drops one while holding the other, opening the contacts. Pushing the knob in first releases a sliding gear type clutch and then moves the cam off the sides of the switch blades, allowing them to drop, and the cam to reset. Closure of the contacts is delayed until the pushbutton knob is released by an axial latch which moves under one blade when the knob is pushed.

摘要： A timing device controls a group of electric heaters, turning them on in sequence in response to call for heat by a thermostat and turning them off in sequence when the call for heat is satisfied. The timer has two stopping points, one with the heaters off and the other with the heaters on. A single switch controls the timer motor and is opened by a timer can at the off and on positions. The switch is held open at the off position by an off latch and at the on position by an on latch. These latches are released by a solenoid controlled by the room thermostat. The latches are also controlled by a timer cam, the off latch being held released when the timer is in the on position, and the on latch being held out at the off position. The load switches for the heaters are also opened instantly by a second solenoid responding to an unfavorable condition. This same action releases the on latch to cause the timer to return to the off position.
摘要翻译：定时装置控制一组电加热器，响应于恒温器的加热而按顺序打开它们，并且当满足热量调用时按顺序关闭它们。定时器有两个停止点，一个加热器关闭，另一个加热器打开。单个开关控制定时器电机，并在断开和关闭位置由定时器打开。开关通过关闭闩锁在关闭位置保持打开，并在开启位置通过闩锁保持打开。这些闩锁由室内恒温器控制的电磁阀释放。闩锁也由定时器凸轮控制，当定时器处于打开位置时，关闭闩锁被保持释放，并且开启闩锁被保持在关闭位置。用于加热器的负载开关也由响应于不利条件的第二电磁阀立即打开。同样的操作会释放开锁定器，使定时器返回关闭位置。
