Title: Chord progression finder
Inventor: BEZEAU ROBERT A JR
IPC: G10G1/02
Filed: 1991-01-25
Abstract: ABSTRACT OF THE DISCLOSURE      A chord progression finder for determining each and every tone of a selected musical scale in a selected key note and each and every tone of its relative musical scales, as well as the various chords playable for the selectedmusical scale and its relative scales, while simultaneously providing information on which keys or frets of a musical instrument are to be played for producing the indicated tones. A base has printed information pertaining to a particular musical instrument and also fingering patterns for playing toneson that instrument arranged in a predetermined sequence indicative of any number of desired musical scales. A slidable, transparent first overlay is slidably connected with the base, and has printed thereon the letter designations for the musical tones arranged in a predetermined sequence so as to cooperate with the fingering patterns on the base in order to selectively indicate to a user the finger positions on the subject musical instrument that will produce the tones of a selected musical scale and its relative scales. A slidable, transparent second overlay is also slidably connected with the base, and has thereon indicia indicative of chord numbers arranged in a predetermined numeric sequence. The base and the first overlay cooperate with the second overlay to indicate to the user the tones and finger positions on the subject musical instrument that will produce the specific chord voicings of the selected scale and its relative scales. These chords can then be used to form chord progressions, as the user may thereupon select.

Abstract: Routing logic means (RL) for a communication switching element (ISE) of a self- routing multi- stage switching network and able to transfer cells or packets of information from any of its inlets (I1-32) to any of its outlets (O1-32).  The outlets of the switching element are arranged in routing groups containing one or more of them and of which the identity is derived by the routing logic means from an output- port- address (OPA) identifying an output of the switching network and contained in the self-routing- tag (SRT) associated to the cell.  This cell is then transferred to one of the outlets belonging to the selected routing group.       The routing logic means (RL) are also able to control the transfer of a cell through the switching element according to the execution of a predetermined routing function selected amongst a plurality of routing functions (RS, DI, MC, BH, IS).  This routing function to be executed is selected by the routing logic means according to a routing- control- code (RCC) also contained in the self- routing- tag (SRT) and each value thereof identifies a specific transfer pattern constituted by a predetermined sequence of routing functions to be executed in the switching elements (ISE) through the switching network (SN).

Title: Electronic control of clothes dryer
Inventor: JOSLIN DAN F
IPC: D06F58/30
Filed: 1991-04-04
Abstract: ABSTRACT      A control system for a clothes dryer is disclosed.  A microprocessor monitors the heated inlet air temperature and the exhaust temperature.  If the inlet temperature exceeds a high limit value a given number of times, an air blockage indicator is activated.  Degrees of dryness are measured by the number of times the inlet temperature has dropped below a threshold value while the heater is off because the exhaust temperature has exceeded a desired value.  An estimated drying time is calculated and displayed to the user based on a linear function of the inlet and exhaust temperatures measured at the beginning of the cycle and again a short time later.

Patent CA-2040944-A1 (CA)
Inventor: BASS RONALD MARSHALL
IPC: G01F1/86
Filed: 1991-04-22
Abstract: The suspension density of a pneumatically transported solid, such as coal, is obtained by using a combination of a radial gamma ray densitometer and a second, fast-response density metre. The combination is required to get the desired combination of accuracy and response time. The second measurement is used for its fast response time and may be used to control operating conditions of a gasifier. The slower, but more accurate, radial radiation measurement is used to recalibrate the second measurement approximately every 10 seconds and correct for drift thereof. The drift in the second measurement is sufficiently slow that high accuracy can be maintained by the recalibration technique.

Abstract: A trash shredding device (10) includes an annular drum (41) which carries vertically spaced segmented blade members (47) in tracks (48) formed therein. A paddle (44) rotates within the drum (41) with its radially outer end (46) being adjacent to the blade members (47). Trash is introduced at one axial end of the paddle (44) and is forced against the blade members (47). The trash shredded by this action is discharged from the device (10) at the other axial end of the paddle (44). The average overall sharpness of the blade members (47) is maintained by placing a new blade member (47) in the first of the tracks (48) while at the same time removing the oldest of the blade members (47) from the last of the tracks (48).

Title: Process and apparatus
Inventor: HARRISON GEORGE EDWIN
IPC: C07C67/08
Filed: 1990-01-16
Abstract: Esterification is carried out in a column reactor (14) in which there is a plurality of esterification trays (15) each having a predetermined liquid hold-up and containing a charge of a solid esterification catalyst thereon, e.g. an ion exchange resin containing -SO3H and/or -COOH groups. A liquid phase containing the carboxylic acid component, e.g. a fatty acid mixture, flows down the column reactor from one esterification tray to the next downward one against an upflowing alcohol vapour stream, e.g. methanol vapour. Relatively dry alcohol vapour is injected (21) into the bottom of the column reactor. Water of esterification is removed from the top of the column reactor in the vapour stream (26), whilst ester product is recovered (23) from the sump of the reactor. As the liquid flows down the trays it encounters progressively drier alocohol and the esterification equilibrium reaction is driven further and further towards 100 % ester formation. A polishing reactor (304) operated under liquid phase conditions may follow the column reactor, the ester-containing product from which is mixed with further alcohol before admission to the polishing reactor.

Title: Method for reducing lost motion and wire distortion in spring clutches
Inventor: RUDE EDWARD T
IPC: F16D41/20
Filed: 1991-02-20
Abstract: ABSTRACT A spring clutch for limiting lost motion during release is provided.  The spring clutch includes a shaft, a helically wound coaxially mounted spring for making frictional contact with the shaft, and means, such as a tang element, for selectively applying a loosing force to at least one end of the spring for rotation thereof with respect to the shaft.  The inventive spring clutch further includes means for urging the spring toward the shaft when the spring is rotatably loosened.  As a result, radial movement of the spring away from the shaft is substantially prevented.  The urging means may be retained by a housing coaxially mounted about the shaft and may be chosen from a boss or an auxiliary spring.  Preferably, the urging means is located at about 90 degrees along the outer radial surface of the shaft from the end of the spring at which the tang element is located. In another embodiment, a core is coaxially mounted within the shaft such that the spring is located between the shaft and the core and the urging means is retained by the core.

Abstract: ABSTRACT OF THE DISCLOSURE   An electrically heatable transparency such as may be employed in a vehicle for defogging, defrosting or deicing the windows of the vehicle has the capability of being powered from either an internal or external power source.  The transparency includes an electroconductive member in the form of a transparent conductive coating on a major surface of a glass sheet of the transparency.  Bus bars contact the coating along opposed edge portions of the transparency and extend to an outer peripheral edge portion of the transparency via extensions of the bus bars for electrical connection to the power source.  Connection to the external power source may be accomplished by use of a plug which is inserted into a household outlet connected to a utility supplied alternating current power source.  A diode along the connecting wires acts to reduce the amount of power supplied to the transparency from the alternating current power source.
