A check-out counter for use in retail stores and including an automatic bag opening mechanism. The check-out counter consists of two counters arranged in a generally T-shaped configuration. A bag loading recess is formed in one of the counters at the intersection of the two counters and the bag opening mechanism is adapted to locate an open bag in the bag opening recess. The counter also includes a cash register support which is mounted for movement between two positions relative to one of the c...

The grate is supported in raised, operative position by a raising and lowering mechanism. For cleaning, the grate is lowered onto track rails in an air chamber below the grate. By opening a door in the furnace air jacket the grate may be pulled out onto exterior track rails for cleaning. The grate is equipped with a water cooling coil and flexible hose connections which accommodate travel of the grate into and out of the furnace without disconnection of the water supply. When the grate is pulled...

The specification discloses a merchandise check out system in which a cart in which the customer has collected the merchandise is presented to a check out station so that a check out clerk in the station can pick up the articles of merchandise from the cart directly, while a second cart in end to end relation with the first cart has bags therein into which the merchandise can be placed directly by the check out clerk, thereby eliminating the counters and conveyors. The basket of the cart is open...

A solid disc is attached to a hinged, split cylinder. A lock is on one hemicylinder so the device may be secured over a door knob to shield the keyhole of a knob lock with the solid disc. A steel spring on the inside of the disc provides a holder for a key to the knob lock and a lining of sponge rubber inside the hemicylinders makes the device adaptable to several size knobs.

A servomechanism system coupled to a spectrophotometer provides direct and simultaneous read out of the transmittance, optical density, concentration and rate of chemical reaction of a solution being analyzed. To calculate rate of chemical reaction, a circuit differentiates an optical density signal modified by a circuit which selectably limits the maximum rate of change of the signal. Circuits associated with the servomechanism control as adjustable and dynamic deadband compensation network, an...

The roll out stand for a paperboard corrugator is an L-shaped vehicle which eliminates the need for manually pushing rolls into position for elevation by arms on the vehicle.

A brown out detector includes a first resistive element connected to a first voltage and a first node. A capacitor is connected to the first node and a second voltage. The detector also includes a second transistor and a third transistor. The second transistor has a drain connected to a second node, a source connected to the first node, and a gate connected to the first voltage. The third transistor has a source connected to the second voltage and the capacitor, a drain connected to the second n...

A constant stream of liquid per unit of time is dispensed under normal pressure from a storage vessel by means of a metering element which is rigidly connected to a float and whose diameter is smaller than the internal diameter of the outflow pipe or tube, the vertical position of the metering element changing with the liquid level in the storage vessel.
