Abstract: The quantitative supply apparatus of powder coloring agent can measure the powder coloring agent through a measuring groove provided on a rotary shaft and supply it directly to the raw material inlet opening of an injection moulding machine. The measuring groove on the rotary shaft can be adjustably changed properly in volume along a length direction. A container for the coloring agent is disposed on the top portion thereof and a hole in the bottom portion of the container is in contact, in a location covering the measuring groove, with the top portion of the rotary shaft. The coloring agent which has dropped from the measuring groove through the rotation of the rotary shaft is adapted to be introduced to the inlet opening of an ejector, and furthermore to the be supplied out of an exhaust side of the ejector to the inlet opening of the injection moulding machine through compressed air.
Abstract: Method and apparatus for heating ladles of the type commonly used in the foundry and steel industry is described whereby fluidized bed technology is employed to achieve greatly improved fuel efficiency. In the method, the particles forming the substance of the bed are drawn directly into the ladle from a mother fluidized bed unit wherein a flow balancing is effected to establish a relatively steady state, simultaneously as the flow to various ladles under treatment may be changed. The invention is particularly adapted to the use of coal as a fuel.

Abstract: Manual and/or accelerator pedal auxiliary controls for conventional vehicular braking systems. The manual control is adapted to the steering column of the vehicle and is mounted for auxiliary actuation, relative to the conventional brake pedal system of the vehicle. The accelerator pedal control which may be used in supplement or in auxiliary relation to both manual and conventional brake pedal control, is adapted to simultaneously prevent inadvertent acceleration during the braking function.
Abstract: A device is provided which permits the simultaneous cutting or bisecting of a plurality of tires. Large, vertically mounted, circumferentially slotted wheels each adapted to receive a circular cutting blade in each slot, receive the tires. The cutting blades are mounted overhead on a shaft which traverses a pivotally mounted beam which is raised and lowered by a piston. A brake is provided for engaging the tread of the tire, and tensioning means engages the lower rim of the tire to exert a downward pressure when the overhead beam is lowered. Turning power is provided to the cutting blades by means of belts or chains which connect a motive source with the shaft on which the blades are mounted. Collars on either side of the cutting blades engage the tire tread when the blades are lowered to turn the tire. A plurality of slots and corresponding cutting blades can be provided for each wheel with spacers to determine the width of sections cut from the tire.
Abstract: A friction material composition comprising asbestos fibers, mineral fillers which are heat stable, friction modifiers such as metal particles, abrasives, elastomer and ground polymerized and cured cashew nut shell oil wherein compositions are added which will favor the deposition of carbon at elevated temperatures and reduce the amount of intermediate decomposition products such as may cause fade. The invention is such as to permit the use of higher bond ratios and consequently produce better wearing, quieter friction materials which are more constant in action and kinder to the drum or disc against which they operate, maintaining a desirable high static friction when cold without an attendant fade condition when used under high energy conditions.
Abstract: Combined Lighthouse and Wind Direction Indicator including a tower wherein the tower houses a light source and a signal target in coactive relationship, the target preferably consisting of a luminescent globe, the globe being ring mounted for a semi-floating, reactive positioning in response to the vectors of prevailing winds. The light source is adapted to present a diffused/suffused aura about the globe, the aura being of less intensity than the intensity of the light which may be focussed within the globe, per se.
Abstract: Fuel feed apparatus for internal combustion engine characterized by the coactive disposition of fixed injectors and valves, interposed between fuel tank, pump, and carburetor of the engine. The principal component of the invention comprises plural fixed injectors in the fuel feed line, having the effect of substantially fully atomizing the fuel under control of in-line valves, whereby to feed the carburetor with a prepared mist of fuel under constant pressure thereby creating a substantial economy in the operation of the engine and a great saving in fuel.
Abstract: An obstruction safety detector having coactive spokes and flexible electrical conductors, mounted relative to dual tires of a vehicle for flash signalling the presence of an obstruction such as a stone, between adjacent tires forming the duals or tandem duals, including a chassis-mounted flexible detector adapted to deflection by the obstruction between rolling tires. The detector, upon deflection, closes an electrical switch in an electrical signalling circuit, which when thus closed, transmits intermittent current to a signal on the instrument panel of the vehicle, thereby warning of the obstruction.
Abstract: The apparatus provides for the rotation and precise positioning of miniature train turntables so as to allow miniature locomotives and/or other miniature railroad rolling equipment to roll onto, or off of, the miniature turntable from, or to, the track to which the said apparatus has positioned the miniature turntable. Additionally, the apparatus provides electrical circuitry for the determination of the phase relationship between the miniature train turntable and the position of interest; in the case of electrically driven miniature trains, it provides circuitry for the electrical activation of the track to which the apparatus has positioned the miniature turntable; it provides circuitry for maintaining the polarity of tracks peripherally related to the miniature turntable so as to allow the movement of miniature locomotives and/or other miniature railroad rolling equipment onto, or off of, the miniature turntable from, or to, said tracks peripherally related to said turntable.
Abstract: Liquid rheostat system especially a water rheostat, employing the principle wherein electrical energy may be dissipated in the form of heat, by passing the electrical current through a liquid resistor or electrolyte, and wherein the apparatus is reasonably portable, inexpensive, and economical to operate and maintain. The invention readily compensates in use for variations in respective resistivity of fresh and/or brackish waters in a test mixture whereby to provide sufficient initial resistance as well as an adequate range of control of resistance, while maintaining current density within the desired limits. In use the heat energy developed is absorbed and removed by the controllable water mixture which in operation of the rheostat system continuously flows out of the rheostat.

Abstract: A device for automatically focusing an image in an optical system such as a camera wherein a photosensitive array having a plurality of discrete sites is positioned in the focal plane of the optical system to dissect the image into segments and determine the light intensity at each segment. Means are interposed in the focal plane to vary the focus of the image, the illumination of the photosensitive array being dependent on the degree of focus of the image. The discrete sites have a charge produced thereon depending on the degree of illumination. Address means scan the photosensitive array and read out the charges on the discrete sites to form a pulse train. Discrimination means are connected to the address means to determine when the frequency of the pulse train is maximized to indicate sharp focusing of the image, as the focus of the image is varied.
