39567052, May 11, 1976

Filed:

Mar 15, 1974

Appl. No.:

5/451720

Inventors:

Robert Mayer - Ardmore PA

Assignee:

Sun Oil Company of Pennsylvania - Philadelphia PA

International Classification:

H03D 1300
H03K 520

US Classification:

328133

Abstract:

Pulses produced by a stream flowmeter, at a repetition rate proportional to the actual flowrate of a liquid, are compared in a counter arrangement with pulses whose repetition rate is the demand flowrate for this liquid. The circuit produces an alarm whenever the difference between the actual flowrate and the demand flowrate is greater than 6%, or 10%. The alarm is inhibited until after 45 seconds subsequent to startup of the blending system for which the said liquid serves as one component.

International Classification:

G05D 1113

US Classification:

13710121

Abstract:

A system for injecting a predetermined amount of additive fluid into a main stream of fluid which controls the amount of additive injected by a timing circuit. A pump continuously circulates the additive through a circuitous path having a valve which diverts the additive into the main stream. A control system receives signals from a turbine meter in the main stream and opens the valve a predetermined length of time at a frequency depending on the signals received from the turbine meter, thereby maintaining a constant concentration of the additive in the main stream.

US Classification:

235 92FL

Abstract:

In a liquid dispensing apparatus, a train of control pulses are produced at a rate representative of equal fractional parts of a unit volume of the liquid being dispensed, and for each of these control pulses a divider gates to an output circuit a number of pulses (derived from a continuously-operating generator) digitally equal to the price per unit volume of the liquid being dispensed. The gated pulses appearing in said output circuit are counted in continuous fashion by a counter which, during a sustained operation, produces a resultant output pulse at the conclusion of every one thousand pulses fed to its input. These latter output pulses are fed to decade counters which drive the final display devices for exhibit or indication of the total price.

International Classification:

G05D 706

US Classification:

137486

Abstract:

In order to obtain very close control of the flowrate of a fluid through a conduit against a predetermined desired flowrate, a pulse generator is employed to produce pulses at a frequency representing the desired flowrate, and a flowmeter issues similar pulses representing the actual flowrate. First and second difference pulse streams are digitally derived to represent the difference by which the actual flowrate either exceeds or falls short of the desired flowrate, and these difference pulse streams are applied, respectively, to count down and count up inputs to an up/down counter. The instantaneous count held within the up/down counter is translated to an analog signal by a digital-to-analog converter, and the analog signal is applied to the input of a two-wire transmitter. The two-wire transmitter drives a valve-actuating motor, such as a d-c torquemotor, to correct the valve position as necessary to obtain and maintain the desired flowrate.

US Classification:

244 7R

Abstract:

A tiltrotor aircraft includes a spanwise-flow redirector having a pair of flow-redirection panels respectively mounted on the aircraft's mid-fuselage area for rotation about a panel pivot axis between a stowed position and a deployed position. In the stowed position, each panel is substantially flush with an adjacent surface of the mid-fuselage area. In the deployed position, each panel is raised into the path of one of the inbound spanwise flows generated by the aircraft's rotors during hover operation, whereupon each panel redirects the respective one of the inbound spanwise flows either forward or aft of the other inbound spanwise flow. In this manner, the deployed panels prevent stagnation of the inbound spanwise flow atop the mid-fuselage area while further serving to minimize re-ingestion of merged spanwise flow into the rotors, resulting in decreased airframe download forces, increased rotor thrust, and reduced noise levels during hover operation.

Assignee:

Suntech, Inc. - Wayne PA

International Classification:

G05B 1118

US Classification:

62171

Abstract:

A control system for automatically controlling the operation of a plurality of fans for a cooling tower so that the minimum number of fans and the lowest speeds are used to provide the required cooling necessary at any one time. The fans are individually controlled in response to the temperature of the working fluid, to be either off or operated at a low or high speed so that as the temperature of the working fluid increases, more fans are turned on first to their low speed and then to their high speed. Safety features are provided for starting the system and for changing the speeds of the fans to prevent damage to the control system and unnecessary wear on the fan motors.

International Classification:

B67D 522

US Classification:

222 28

Abstract:

A blending-type motor fuel dispensing apparatus operates to blend together, in various proportions, two liquid motor fuels (gasolines) of different octane ratings, to produce various grades of product. The quantity and cost displays, and also the automatic control of the blend during dispensing, are based upon the summation of two sets of pulses, the number of pulses in each set being proportional to the integrated flow rate of a corresponding one of the two fuels. The pulses are counted and multiplied by a price per gallon, which has been previously set for the grade being dispensed, to provide a cost display. A pulse comparison circuit, which compares pulses representative of the flow of one fuel with a percentage (settable for each blend) of the summed pulses, is used to control the proportioning of the two fuels. Selection of a desired product for dispensing (one out of five products, for example) is made by operating an appropriate pushbutton; when this is done, the proportioning control valves are automatically pre-positioned to a setting corresponding to the particular selection that has been made.

Abstract:

A circuit for detecting flow pulses in a fluid stream includes a thermistor placed in the fluid stream for sensing changes in the flow rate, an R-C filter in circuit with the thermistor for passing pulses having a specified minimum flow rate change, and a square wave generator for producing an output signal when the filter passes a pulse.
