Abstract: ABSTRACT OF THE DISCLOSURE      A fan for moving a gaseous fluid, e.g., air, is described in which the high audible frequency noise resulting from the phenomenon occurring at the trailing edges of the blades, known as vortex shedding, is reduced.  This is accomplished by notching an edge of each of the blades so that the pattern of vortices leaving the blade, which causes the noise, is disturbed and a turbulence condition engendered.  The turbulence distributes the pressure fluctuations resulting from movement of the blades through the fluid over a relatively broad band of frequencies and reduces the annoying noise frequencies.  Various notch configurations are disclosed.

Title: D.c. motor position control
Inventor: TURINI GERHARD
IPC: H02P3/10
Filed: 1978-02-08
Granted: 1981-06-23
Abstract: Abstract of the Disclosure According to the invention, the angle through which a d.c. motor rotates is determined by two position-sensors.  The outputs of the position-sensors are connected with a control circuit, to which is also passed a correction signal determining the direction of rotation of the motor.  The control circuit produces control signals which are passed to the motor drive arrangement of the d.c. motor.  For accomplishing the rotation of the motor from a first position to a second position, the motor drive arrangement produces first an acceleration current, then a deceleration current and, when the motor has arrived in the range of the position-sensors, a correcting current in either one direction or the other.  The motor is placed in the desired position with the aid of the correcting current and the motor is then switched off.  In case the motor should stray from the desired position, it may be returned to that position by once more switching on the correcting current for the required direction.  The position-sensors comprise a timing disc having an aperture and two light sensors, adapted to be either interrupted or not interrupted by the sides of the aperture.  The invention is useful in non-mechanical printers, e.g. for controlling the movement of pivoting roller between two positions.

Abstract: METHOD OF RECOVERY OF TAR SANDS MATERIAL          Abstract of the Disclosure A method of recovery of tar sands material from a subterranean layer of such material underlying an overburden comprises floating a surface rig on an artificial lake and sinking a mining string from the rig down through the over-burden and into the material.  A jet of water is projected from the string into the material to soften and erode it whereby to form a cavity and generate a slurry of the material and the water.  The slurry is forced to the surface for recovery of the material, including separating bituminous components from the material to yield sand tailings.  These tailings are then discharged into the lake to form a surface layer and/or to form dikes for assisting in retaining water on the overburden.          By this procedure the tailings effectively add to the overburden to compensate for the subsidence of the overburden caused by removal of the material of the subterranean layer.

Abstract: Abstract Disclosed is a tablet dispenser for fumigating agricultural commodities, such as grain, animal feed, and the like, comprises a container shaped to receive a plurality of pesticide tablets therein, and  including a base with a dispenser aperture therethrough.  A rotor is rotatively mounted in the container base, and includes an upper portion, a medial portion, and a lower portion.  The medial portion of the rotor is spaced apart from the container sidewall, and forms an annularly shaped channel therebetween which is proportioned to receive therein a single file ring of the pesticide tablets, each oriented on a circumferential edge thereof.  The lower portion of the rotor extends outwardly of the medial portion to form a base surface of the channel on which the tablets are supported, and includes a dispensing aperture therethrough positioned for selective alignment with the container base aperture.  The upper portion of the rotor is shaped to urge the tablets toward and into the channel, whereby relative rotation between the container and the rotor regularly dispenses the pesticide tablets from the dispenser.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a method of pro-ducing an optical waveguide by melt-drawing a transparent glass rod which has been produced by collapsing a porous glass rod after being doped with a dopant material by depositing said material at the surface of the micro pores in order to increase the refractive index of the collapsed glass rod.  A waveguide having higher mechanical strength and lower trans-mission is obtained by drawing the glass rod at a temperature very close to the melting point of the outermost portion of the fiber without causing any overmelting or bubbling in the core portion.  The drawing process is made possible by match-ing the viscosity and characteristics of the outermost lower-refractive-index portion to those of the central higher-refractive-index portion.
