US Patent:

54295505, Jul 4, 1995

Filed:

Sep 1, 1993

Appl. No.:

8/115319

Inventors:

Richard A. Mazur - Naperville IL
Gary Watts - Buffalo Grove IL
Donald E. Raterman - Deerfield IL
Robert J. Crawford - Palatine IL

Assignee:

Cummins-Allison Corp. - Mt. Prospect IL

International Classification:

G07D 316

US Classification:

453 10

Abstract:

A coin sorter for sorting mixed coins by denomination. The apparatus comprises a rotatable disc which has a resilient surface for receiving coins and imparting rotational movement to the coins. A stationary sorting head has a contoured surface spaced slightly away from and generally parallel to the resilient surface of the rotatable disc. The stationary sorting head sorts and discharges coins of different denominations at different exits around the periphery of the stationary sorting head. The sorting head includes a separate exit channel for each denomination of coin, and a sensor for each coin denomination within the exit channel for that denomination. An encoder monitors the movement of a sensed coin on the rotating disc downstream of the sensors by monitoring the angular movement of the disc. Further, a coin discriminator is used to detect foreign and counterfeit coins and to prevent the detected invalid coins from being discharged with the valid coins.

International Classification:

G06F 738
G06F 1531

US Classification:

364724

Abstract:

A circuit arrangement for filtering input signals carried on PCM channels. The circuit arrangement includes a plurality of digital signal processors arranged in a parallel manner each having a set of filtering operations, a multiplexer for distributing the input signals to each digital signal processor, a processor for analyzing frequency characteristics output by the digital signal processors and an addressing PROM for controlling a correspondence between the PCM channels and the filtering operations in each of the digital signal processors.

H04M 1108

US Classification:

379 67

Abstract:

A telephone system employs a novel message system for calling parties. The switch controller includes selectable and programmable announcement machines, while the telephone devices include indicators which allow call transferees the ability to determine the reason the call was transferred, e. g. , the called telephone was busy, did not answer or the called telephone party is in conference. When desired, a telephone party is capable of programming the switch controller to reply to any particular incoming phone calls with one of a number of customized or preselected messages.

International Classification:

G07D 314

US Classification:

194318

Abstract:

A coin sorter for sorting mixed coins by denomination includes a rotatable disc, a drive motor for rotating the disc, and a stationary sorting head having a lower surface generally parallel to the upper surface of the rotatable disc and spaced slightly therefrom. The lower surface of the sorting head forms a plurality of exit channels for guiding coins of different denominations to different discharge stations around the periphery of the disc. A plurality of coin sensor/discriminators are mounted in the stationary sorting head over the rotatable disc for discriminating between valid and invalid coins guided by said stationary sorting head. At least one coin sensor/discriminator is mounted in each of the plurality of exit channels.

International Classification:

G08B 2100
D06F 3300
G04B 4700

US Classification:

340679

Abstract:

Disclosed are two arrangements for remotely indicating the status of a washing machine and/or a dryer. In one arrangement, a current sense circuit is employed along with an optional vibration sense circuit to detect whether or not the washing machine or the dryer are on or off. At a change from on-to-off or from off-to-on, the status of the washing machine or dryer is transmitted over the air to a receiver for status display to the operator. In the second arrangement, detection of the status is internal to the washing machine and the dryer and the status includes additional information such as the type of cycle and the amount of time left before the cycle finishes. To avoid constant transmission of such information, the receiver includes a timer which is synchronized to the washing machine/dryer timing circuits.
