Abstract: Stirring apparatus for stirring particles in a liquid medium comprising a cylindrical stirring vessel having a stirring rod extending within the vessel to stir its contents. The rod has a bulbous tip which describes an orbital path in the vessel to sweep out an annular trough or channel formed in the bottom of the vessel. The annular trough or channel is contoured in section to follow the flow lines set up in the medium by secondary motion stirring effects. In this way accumulation of particles due to the secondary motion, which would otherwise occur at the corners and center of the bottom of the vessel, is avoided. The apparatus is advantageously useful in cell culture research particularly for stirring microcarriers in a liquid culture medium because it becomes possible to maintain the microcarriers in uniform suspension at lower stirring speeds than heretofore possible thus avoiding damage to the growing cells and improving overall cell yield.

Abstract: For the improved combustion of hydrocarbon compounds, for example those contained in gasoline, diesel fuel etc., in internal combustion engines a liquid composition comprising hydrogen peroxide, water, aliphatic alcohol having 1-4 carbon atoms, and preferably thin lubricating oil and anticorrosive is admixed with the fuel air mixture in the internal combustion engines.

Abstract: A workman's lift platform apparatus has a vertically swingable and extensible boom with a workman's platform at the outer end. A color coding indicating the amount of boom extension is provided on the fly section of the boom, visible to the workman in the platform, and an indicator plate having corresponding color coding is provided adjacent the controls on the platform. The indicator plate in the form of a drum is driven proportionately to the angular movement of the boom by a pair of sheathed, push-pull cables, or by a sheathed torsion cable. In other embodiments, the indicator plate is tilted in proportion to the angular movement of the boom by a sheathed push-pull cable or by a parallel bar linkage. A cursor is provided adjacent the indicator plate, and is part of a gravity-operated pendulum.

Abstract: Mulit-mode voltage and continuity testing apparatus is disclosed for effecting a single pole phase mode of testing, and comprises first and second testing terminals, a loudspeaker, a battery energized oscillator having a control input, a control transistor, and first and second resistances. Circuitry is provided for directly connecting the battery through the emitter and collector of the control transistor to the control input of the oscillator circuit, and the first testing terminal to the base of said control transistor, whereby the testing apparatus effects a single pole phase mode in which a voltage source to be tested is connected to said first testing terminal.

Abstract: A dental care device which encourages more frequent tooth cleaning. The device comprises a brush body consisting of a brush core provided with bristle members, which brush body is surrounded in full or in part by a solid, palatable mass of physiologically acceptable materials. The device has the appearance of, and is to be treated as, a sweet.

Abstract: A dispensing and weighing system for multiple ingredients, including a plurality of individual ingredient batch weighers. Each batch weigher includes apparatus to store and dispense a particulate material to a scale from which the weighed portion of the material is intended to be delivered to a pneumatic ingredients delivery conduit. The pneumatic conduit discharges into a weighing hopper, where the weight of all of the batches delivered to the hopper is determined. A method for dispensing individual, weighed batches of particulate material, and for determining the total weight of the material actually delivered to a receiver.

Abstract: Method and apparatus for preparing a specimen for observation under the electron microscope by ion erosion. A saddle-field ion source is employed to irradiate the specimen with the specimen held in close proximity spacing with respect to the cathode aperture of the ion source. Such close proximity spacing ensures that the specimen is thinned at a rapid rate comparable with the rates attained with chemical etching.

Abstract: Controls for an aerial lift platform apparatus which has a steerable mobile chassis, a rotatable upper works, and an extensible boom pivoted on the upper works for luffing movement. The controls are grouped to provide a first group of control members in physical proximity to each other for controlling upper works movement and a second group of control members for controlling movement of the chassis. Each of these control members is mounted for movement substantially to simulate the movement which is controlled. A third group of control members is for controlling the engine, and are in physical proximity to each other. The control members are mounted on a control console having near-horizontal and near-vertical surfaces from which the control members extend, the vehicle control member for drive and steering extending upwardly from the near-horizontal surface.

Abstract: A hitch is disclosed which readily attaches itself via hitch assemblies to the bumper of an automobile and simultaneously secures the cross bar or draft bar of the hitch in a manner which requires no threading devices to obtain the securing action. In fact the securing action is by the simple movement of a lever into an over centered position on the hitch assembly and this in cooperation with two chains thereof, one attached to the upper margin and the other attached to the lower margin of the bumper or possibly the frame of the car securingly clasps not only the hitch assembly to the bumper but the draft bar to the hitch assembly. Preferably, two hitch assemblies are provided one located near each end of the cross or draft bar. Thus with "snaps" of each lever into over center position the bumper hitch is secured to the automobile awaiting for connection of the trailer tow bar thereof for coupling to an awaiting trailer.
