Embodiments described herein pertain to checkout stands and related components. Checkout stands illustratively include scanners and cash drawers. In some embodiments, cash drawers are located downstream from scanners. In some embodiments, checkout stands include item entering and exiting sides. Scanners are illustratively positioned between an entering side and a cash drawer, and cash drawers are illustratively positioned between a scanner and an exiting side.

A cash drawer housing holding a cash drawer for use in a check stand and placed over a scanner is disclosed. The cash drawer housing has a moveable base member that is located above the scanner. The moveable base member allows the scanner to be moved without moving the cash drawer housing. The base member rotates or moves in response to contact from the scanner below during removal. The moveable base member can be scanned during removal by a latch to hold the base member out of the way to permit easier scanner removal and reinstallation.

A speed controlling arrangement for an electric motor is provided with a pneumatic foot controller which includes a bulb that is opened to the atmosphere between operative periods to equalize pressure in both the bulb and a transducer, but is closed when foot pressure is applied to the bulb to actuate the transducer.
摘要:
An SCR motor speed control system having a capacitor for triggering the SCR into conduction is provided with circuitry for limiting the top speed of the motor by sensing the armature back EMF generated during the non-conducting period of the SCR to determine the motor speed. When the speed is above a predetermined threshold value, a transistor is turned on to short circuit the charging path of the capacitor.

The present disclosure includes a method for providing pricing information. In some implementations, a method for providing pricing information includes receiving, from a first subscriber, a request for pricing information of one or more retailers. The request is associated with a unit provided by a retailer different from the one or more retailers. Pricing information associated with the unit is identified based on mapping information. The pricing information is provided by the one or more retailers. The mapping information maps the unit to one or more units sold by the one or more retailers.

An electronically controlled sewing machine having the capability for lateral feeding in addition to longitudinal feeding is provided with an arrangement for effecting closed path pattern stitching. Selector switches having indicia thereon representative of the direction of sewing effected by operation of the respective switches are positioned so that the indicia visually simulates the closed path pattern.

An operator manipulating means for a programable electronically controlled sewing machine. The operator manipulating means provides an array of switch points, each related in a row, to discrete needle positions attainable by the electronically controlled sewing machine; and in a column, to the least feed increment attainable thereby. The switch array is fabricated using a pair of printed circuits, one of which must be flexible and each having spaced, parallel conductors, and arranged with respect to each other so that the conductors of one are substantially perpendicular to the conductors of the other and are in facing relationship. The printed circuits are separated in a first embodiment by a pair of insulating sheets, each having an array of apertures in spaced registry with each other and aligned in rows and columns with the conductors on the printed circuits. The pair of insulating sheets are separated by a flexible conducting sheets which may be used as a common conductor. Depression of a conductor on the flexible printed circuit through an aperture of an insulating sheet will establish a connection to the flexible conducting sheet, which conducting sheet will be deflected through the aperture in spaced registry to establish a connection with a conductor of the other printed circuit.

Means are disclosed for permitting entry of operator selected stitch points in a switch array which exceeds the capacity of the switch array. In a switch array for a programmable memory of a sewing machine, the columns of switches are representative of the needle position and the rows of switches are representative of fabric position determined by accumulation of feed increments. Each required feed increment is determined by the change of the present stitch position coordinate for feed over the just prior stitch position coordinate for feed. In order to provide for feed increments in the forward direction beyond the number of rows provided, an artificial signal is generated for the just prior stitch position coordinate for feed representative of the first row of switches. To provide for feed increment in the reverse direction, an artificial signal is generated for the just prior stitch position representative of the last row of switches. Feed increment is thus calculated from a new starting point permitting continued operation in a selected direction.

An improved process for making 5,11-dihydro-11-ethyl-5-methyl-8-{2-{(1-oxido-4-quinolinyl)oxy}ethyl}-6H-di pyrido[3,2-b:2′,3′-e][1,4]diazepin-6-one.
摘要:
In an electronically controlled sewing machine having an arm shaft position sensor signalling release of feed data and of needle position data at opposite extremes of endwise reciprocation of a needle bar, depression of a needle up or needle down position button will implement a slow speed drive circuit, and a fast stop brake circuit will stop the needle bar immediately upon the occurrence of a signal from the arm shaft position sensor corresponding to the selected needle position button.
