Abstract: An improved pillow having a head supporting portion and a neck supporting portion. The neck supporting portion having a firmness greater than the head supporting portion. The neck supporting portion is of lesser transverse dimension than the head supporting portion to allow freedom from interference of the pillow with the sleeper's jaw and mouth. In an alternate version, the pillow includes two reversible neck supporting portions of different firmness.

Abstract: A container filling machine is provided with easily demountable nozzles or valves capable of being clamped in position in openings through which fluid product passes from the reservoir to containers. Clamping assemblies, pivotable into engagement with flanges on the nozzles, are fixed to the machine between the nozzles and a single assembly either clamps two of the nozzles in operating position or frees them for removal.

Abstract: A valve mechanism for positive displacement, rotary receptacle filling machines having vertically movable valve stems operable by fixed cam tracks employs cam followers pivoted on the valve stems for movement in a vertical plane and horizontally settable means for locking them against such movement.

Abstract: A positive displacement rotary receptacle filling machine employs a receptacle detecting mechanism which detects the presence or absence of a receptacle in the file being fed to the machine at a point ahead of the filling position of such a receptacle and effects a presetting of the valve operating mechanism of such a machine at a point correspondingly ahead of the initial filling position, utilizing a settable trip shoe separate from the settable valve operating mechanisms of the machine for this purpose. The arrangement described results in a significant extension of the filling arc of the machine, making possible a corresponding significant increase in its speed.

Abstract: Patterns to be applied to a needlepoint design outlined on a canvas panel are first traced in stitch-length markings on a grid of the same mesh size as the canvas mesh size, delineated on a transparent sheet. This sheet is then laid over the canvas panel with its grid aligned with the threads of the panel and the pattern in the desired position thereon. Threads are then embroidered into the panel in alignment with traced pattern. Spacing of repeats of the pattern is effected by tracing at least two delineations of the pattern on the transparent sheet in their intended spacing.

Abstract: A device is provided for sensing the magnitude and direction of angular departures of a towing vehicle from a path which will bring a hitch mounted thereon into engageable relationship with a hitch mounted on a trailer, for registering the changing distance between such hitches, and for indicating the angular values and direction of such departures and the distance between hitches to an operator of the towing vehicle. The construction permits approach of the towing vehicle toward the trailer from any access angle without requiring adjustment of the device for different angles of approach and without introducing error. Automatic scale expansion of the distance indication occurs as the distance between the vehicles shortens.

Abstract: A novel crystal holder for the wavelength dispersive spectrometers of electron microprobes arranges four crystals as a cylinder segment which may be moved to a position in which it partially encompasses the viewing optics assembly so that low Bragg angle settings may be obtained without mechanical interference, while at the same time the interchanging of crystals by oscillation of the cylinder segment on its axis is possible at any position of the crystal holder.

Abstract: An X-ray spectrometer is provided with two channels for detecting characteristic lines of the X-ray source after being scattered by a sample undergoing analysis, in addition to means for detecting electric signals primarily representative of the concentrations of analytes in the sample. In this way, data is collected which facilitates corrections of the measurements corresponding to individual analytes for deviations from linearity of intensity caused by variations in interelement effects, and by variations in total-solids concentration, or density, of the slurry, or matrix, in which the analytes are distributed, and by variations in particle size of the total-solids in the sample. Correction of measurements of total-solids concentration and average particle size of the matrix for each other and for effects of analytes, may also be made.

Abstract: In an industrial dry cleaning operation in which wrinkles are removed from the cleaned garments by suspending them in a heated atmosphere, the garments are rendered soil-resistant by spraying them with a liquid containing a dilute polyfluoroalkyl stain repellent after cleaning and prior to suspending them in a heated atmosphere in which they are heated for a time period and at a temperature sufficient to first evaporate said liquid and then to set the stain repellent concurrently with the removal of wrinkles.

Abstract: Controlled-distortion photocopying apparatus comprises a bifurcate drive mechanism the forks of which are angularly adjustable with respect to each other. Each fork propels a film carriage along a path normal to an exposure slit provided in a film mask disposed between the film carriages and a light source. A transparency to be copied is carried beneath the exposure slit by one carriage and a sensitized film carried beneath the transparency by the other carriage. The dimension of the photocopy normal to the long dimension of the exposure slit is either decreased or increased according to which carriage carries the sensitized film and which the transparency; the magnitude of the dimensional change depending upon the angle between the forks of the drive mechanism.

Abstract: The outer zone or cortex of carrot root, separated from the central zone of wood and pith, is subdivided and roasted, providing a material useful for brewing a beverage simulating coffee and devoid, even when brewed, of identifiable carrot odor.

Abstract: A skate board comprising an elongate body having roller trucks adjacent its ends is moulded of thin flexible plastic and reinforced by an adjustable shock absorber attached to the underside of the body between the roller trucks.
