Alarm signals are processed in a security system in which an on-site detector is connected by a communications link to a central station. A time delay circuit is connected at the site being protected, to the detector, with the time delay means being turned on and off by a time clock. The time delay period permits the alarm system to be activated and deactivated by predetermined procedures to prevent the central station from receiving unnecessary alarm signals.

An indicator system having an electrical timer which becomes actuated after a preselected interval for connecting a source of voltage to a motor. An extension of the motor shaft mounts an actuator that travels between the ends of the extension. After sensing actuator travel at one end, switching means cause the actuator member to reverse its direction to the second end of the extension. At one end of the extension an electrical switch closes a circuit between the voltage source and an electrical...

An alarm circuit is interlocked with the start circuit of power driven industrial machinery such as a coal tipple so that before the machinery can be started, an alarm must be energized for a predetermined time to alert personnel that the machine is about to start. In the event that the machinery is not started within a predetermined time after termination of the alarm, the whole cycle must be repeated.

A method of and apparatus for controlling the selective performance of a plurality of predetermined functions at preselected times. Time and function data representing functions to be performed and the times at which such functions are to be performed are generated. This time and function data are stored in a memory at available storage locations. The stored data is compared to data which is produced by a clock and which represents the time of day then obtaining. If the actual time of day compar...

Apparatus is disclosed for controlling and monitoring the operation of load means that cyclically operate a load device, such as the dosage supply means of a clinical analyzing system. The load means includes a load motor the operation of which is initiated by an actuating switch that is operated by synchronously-driven program means to initially energize the load motor, whereupon a self-latching holding switch is operated from a first condition to a second condition to maintain the load motor e...

An alarm system for detecting and recording the time of arrival home of a young person who has a definite curfew for his or her return. The system allows the parents of the young person to reture for the evening with the assurance that they will be awakened if their son or daughter does not return on time, but will not be disturbed if he or she arrives home on or before the appointed time.

An improved Taguchi Gas Sensor type detection and alarm system for smoke, gases or the like, which is particularly adapted for use in environments where the only available source of electrical operating power is an ordinary storage battery, is provided and employs an electrical oscillator coupled with the storage battery for providing both the low voltage high current electrical power required for activating the Taguchi Gas Sensor and an audio frequency output signal for operating an audible war...

A solid-state delay timed switching circuit includes a delay timing means for delaying the start of an operational sequence. A function timing means is provided for timing the operational sequence, an alarm timing means for timing an audible alarm at the completion of an operational sequence, a power switching means, a power supply and a power turn-off means to de-energize the power switching means.

A security device includes an alarm that is actuated after a predetermined period of no human physical activity, which device includes a clock set to actuate the alarm after a predetermined period of inactivity, an activity sensor that resets the clock when human activity is sensed, and a means to sense an inanimate object, such as a set of keys, and which, when the inanimate object is absent, will not actuate the alarm when the predetermined time period has passed. There is also disclosed means...

A device and method for holding a container in an inverted position to assist in dispensing the contents of the container. A bracket and retaining band are doubled along the length of the container. The retaining band holds the bracket into abutment with the container. The bracket has a mounting portion or mechanism that allows the bracket to be hung from or mounted to a supporting structure. The bracket also includes a portion towards the opposite end of the bracket which stabilizes the bracket...
