A folding, collapsible playroom adapted for compact storage which is designed to encourage active and creative play by children as opposed to passive activities such as watching television. The playroom has first and second frames having transversely spaced apart top and bottom walls and opposite side walls all having front and rear surfaces, thereby defining inner and outer frame faces respectively. The frames are pivotally connected such that they may be pivoted from an open, upstanding position to an abutting, closed storage position. Play accessories are included which may be pivotally mounted on one of the frame inner faces and adapted to be moved from a secured stored position to a deployed, play position protruding substantially forwardly from the frame, upon movement of the frames from the closed storage position to the open, upstanding position. The play accessories having a width greater than the width of either of the two frames individually may be releasably secured to one of the frames for storage and removable for play when the frames are opened.

Collapsible playroom

A gasoline dispenser control and data system comprising a central office and a plurality of local stations, each station having dispenser control functions, data storage functions and communication functions. The station has a dispenser control mode and data entry mode. In the dispenser control mode a dispenser may be set to dispense gasoline, such dispensing of gasoline resulting in the production of pulses which are accumulated in a counter. The dispenser may then be reset for the next sale. Upon reset the counter is returned to zero, and the previous sale is stored in a temporary memory for recall and display, also being stored in two separate permanent memories, one of which is accessible to the station operator and the other of which is not accessible to the station operator. In the data entry mode the station operator can enter data into some but not all permanent memories. The station data system may be telephoned by the central office and each memory interrogated. The central office may also enter new data in the station data system. Means are provided for interrupting transmission for a limited time for operation of dispensers on a limited basis. Means are also provided for automatically entering data such as the amount of gasoline in storage tanks in the station memory, for 'in use' and 'ready' signals for each dispenser, and for an emergency off function.

Control and data system

A storage tank liquid level sensor for indicating levels of two immiscible liquids in the tank wherein a first magnet is carried by a float on top of one liquid and a second magnet is carried by a float on top of the other liquid, the first magnet operating a switch to indicate when the one liquid reaches a predetermined level and the second magnet moving a coded tape with respect to a read head in accordance with changes in the level of the other liquid, a transmitter to transmit data from the read head, a receiver for such data, an arithmetic logic unit to convert the data to binary coded decimals, a memory unit for storage of BCD data, and a display unit for selectively addressing the computer and displaying selected data.
