Abstract: Extracts which were recovered with aqueous extraction media from the pollen of plants inhibit the growth of tumor-cells and stimulate at the same time the metabolism of normal healthy cells. Said extracts of pollen which do not contain more than 5% by weight of proteins having a high molecular weight or which are completely free of such proteins of high molecular weight, are used as active ingredient of corresponding pharmaceutical preparations and they are used for treating cancer, tumors and leukemia in human beings or warm blooded animals. Living leukemia cells are rapidly killed by said extracts. The pollen extracts in question are a yellowish-white product and they usually contain, referred to the dry weight of the pollen extracts, at least 70% by weight of carbohydrates, 5-12% by weight of amino acids, peptides and/or proteinous substances and furthermore water soluble vitamines of the group B and mineral constituents.

Abstract: Apparatus for feeding sheets from a plurality of supplies to an output location in which a toggle linkage normally releasably positions the conveyor in an operative position from which it may be moved around an axis adjacent to one of its longitudinal edges to permit access to the feed path.

Abstract: A turret unwinder in which a carriage mounted on the turret for movement between limit positions respectively adjacent first and second diametrically opposite winding axes supports a bumper roll for movement from a neutral position to respective fired positions in engagement with rolls on the winding axes and first and second knife bars adapted to be fired respectively to sever webs being unwound from rolls on the two axes.

Abstract: A sheet length detector with skew compensation for use in apparatus for batching and counting currency, food stamps or the like. Sheets are advanced past a pair of sheet sensors which are disposed at transversely spaced locations on the feed path on either side of the nip formed by a pair of opposing feed members. A timing interval is begun upon the actuation of both sheet sensors and ended upon the deactuation of both sensors following their initial actuation. The duration of the timing interval provides a measure of sheet length. This measure is then corrected for skew, which is determined from the time lapse, if any, between the deactuation of one sensor and the deactuation of both sensors. The corrected measure may be compared with an absolute reference or with the results of a previous length measurement.

Abstract: An aqueous solution of acrylamide is mixed with an aqueous solution containing a polymerization trigger. Firstly at least one of the solutions contains a color indicator having a given color in the solution based on acrylamide and a different color in the solution contained in the trigger, and whose color changeover zone corresponds to the optimum proportions of the reagents in solution. Secondly, during mixing, the respective quantities of the two solutions are adjusted to occupy the changeover zone of the color indicator such that the mixture takes up the color corresponding to the color of the indicator in the solution based on acrylamide. The mixture preferably contains acrylamide, methylenebisacrylamide, and triethanolamide glycol, using ammonium persulfate as the trigger and using bromophenol blue as the color indicator, with the color thereof disappearing after polymerization.

Abstract: Skew-correcting apparatus in which first and second sets of opposing feed rollers each comprise a pair of end rollers and a center roller between the end rollers. The first center roller has a sheet-gripping portion of limited circumferential extent forming a nip with the second center roller, while the first pair of end rollers engage the second pair of end rollers. The second set of rollers are coupled for common rotation; the first pair of end rollers are mounted for rotation relative to the first center roller. The first center roller is driven while the remaining rollers are retarded so that the remaining rollers are normally stationary to align the leading edge of a sheet but are driven by the sheet-gripping portion of the first center roller to advance the sheet through the nip. A downstream feed roller driven synchronously with the first center roller and also having a sheet-gripping portion of limited circumferential extent is used to advance a sheet to the opposing sets of feed rollers.

Abstract: A system for shaping a food product which is initially in the liquid state, such as fresh liquid egg white or yolk, while it is hardening, in which the liquid product is fed to a continuously unwinding band of flexible material, such as Teflon-coated paper which is deformed while in motion from a flat state to the shape of a continuous container and in which the product is treated as by heating until it is hard. After the product is hard the band is restored to its flat state and is drawn in a direction opposite to its original direction while the shaped and hardened product is carried away. Specifically, the means for deforming the band comprises a pair of press rollers having male and female molding parts for marking longitudinal folding lines on the band and flanges for raising the edges of the bands along the longitudinal folding lines. Preferably, the product is heated in a microwave cavity and, during heating, a second band is applied on top of the shaped band to form a steam-tight cover.

Abstract: A buckle assembly in which a base having upstanding sidewalls defines a passageway for receiving a tongue having a recess formed therein. A latch pivotally supported by the base sidewalls above the passageway has a catch portion adapted to extend downward into the tongue recess to prevent withdrawal of the tongue from a passageway and a clamping surface adapted to bear against the upper surface of the tongue upon attempted withdrawal of the tongue from the passageway. The latch is resiliently biased to a limit position defined by stops in which the catch portion extends into the passageway while the clamping portion remains substantially clear of the passageway and the latch handle remains recessed within the sidewalls.

Abstract: The invention consists of the following steps:(a) continuously feeding n1 containers with fresh liquid egg white and n2 containers with fresh liquid egg yolk, the containers having the same shape and being made of a material inert to microwaves, the sum of n=n1+n2 being equal to at least two and n1 being either equal to n2 or different from n2 by one unit,(b) subjecting each liquid egg product to the action of microwaves so that it coagulates in the container, in the form of a homogeneous layer, without however reaching the hard cooked state,(c) extracting the layers from the containers and superposing the extracted layers so that a layer based on liquid egg white alternates with a layer based on liquid, egg yolk, and(d) subjecting the superposed layers to a complementary heat treatment to achieve the desired degree of cooking while at the same time ensuring the complexing of the different layers.

Abstract: The invention consists in making an emulsion of a fluorinated product, in the presence of a derivative of morpholine. The derivative of morpholine may be the morpholine itself, a saturated derivative or a non-saturated derivative, for example morpholinoethyl methacrylate. The fluorinated product may be a fluorinated monomer, for example 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate. Placing in emulsion is effected by adding to the fluorinated product the derivative of morpholine in the presence of a surface-active agent, and by adjusting, with mechanical stirring, the desired quantity of liquid.

Abstract: Documents such as checks, food stamps or the like are successively advanced along a path between a transversely spaced pair of light-emitting diodes (LEDs) and a correspondingly spaced pair of photodiodes to generate signals for counting and misfeed detection. Various error detectors detect sheet misfeed by integrating signals derived from one or more sheet sensors and comparing the integrated signal with reference signals that vary with the drive speed. A doubles detector generates a signal indicating a double feed if the integral of an analog optical density while below a predetermined threshold lies beyond a predetermined limit. A potentiometer permits adjustment of the threshold optical density at which the integrator becomes operative. An LED coupled to the output of a spare amplifier on the chain note board permits detection of the momentary presence of an output signal from a particular error detector.

Abstract: A sheet feeder in which a picker member engaging an end sheet of a stack is actuated to drive the end sheet through a feed nip formed by a feed member and a cooperating member. The picker member is actuated in advance of the feed member to prevent other sheets from entering the nip. Preferably, the picker member is preactuated by coupling it directly to the drive source while coupling the feed member to the same drive source through an electrically actuated clutch.

Abstract: A ballistic helmet body made up of a plurality of plies formed from flat hexagonal blanks of ballistic fabric. Before being formed to the shape of the helmet body each blank is slit along lines extending from spaced points around the periphery thereof toward the center to form a generally circular central area and a plurality of contiguous segments extending outwardly from the central area. When the blanks are formed to the shape of the helmet body, adjacent segments overlap over first portions to leave second portions which do not overlap. As successive plies are laid up they are relatively oriented so that second portions of one ply are covered by first portions of another ply.

Abstract: Apparatus for counting and endorsing documents in which a motor drives respective pairs of feed rollers to move documents along a feed path from an input location and along the feed path to an output location. Movement of an endorser adjacent to the feed path from an inoperative position to an operative position reduces the motor excitation to cause the rollers to move the documents along the path at a slower rate.

Abstract: An energy-absorbing sound-attenuating earcup comprises a rigid shell of an ABS terpolymer that is about 0.090 inch thick so as to crush upon impact at an applied force less than that required to crush the skull of the wearer. The shell has an inner coating of a sound-deadening rubber material to compensate for the reduced sound-attenuating capability of the thinner-than-normal shell. Spaced flanges defining a peripheral channel for receiving a cord of a helmet suspension are formed as staggered series of tabs rather than as circumferentially continuous members to facilitate crushing of the shell upon impact. Resilient earseals disposed between the shells and the wearer's ears comprise first thicknesses of standard polyurethane foam and second thicknesses of slow-recovery polyurethane foam to provide additional impact absorption while permitting the earseals to conform to the wearer's head in cold weather when the helmet is first put on.
