Abstract: An infant safety seat for use in a motor vehicle, having a rigid seat back (12), is adapted to be mounted in a vehicle so that a seated occupant faces rearwardly. The side of the seat back (12) facing away from the occupant has a guide (30) for receiving a shoulder portion (24) of an adult seat belt and a clamp (28, 32) for inhibiting movement of the shoulder portion (24) of the adult seat belt relative to the seat back (12). A cover (40) is arranged, when in a closed position, to enclose the guide (30, 32) and to cause engagement of the clamp (26 28).

Abstract: A sampling mill for grinding discrete materials to obtain a representative sample is provided by this invention. The mill is particularly useful for grinding various foodstuffs such as corn, peanuts, animal foods and the like. The material to be sampled is fed to a rotary worm gear of substantial length connected to a burr plate to feed the material between a second plate. By varying the worm gear with comminuting means, the placement of burrs on the burr plate and the distance between the burr plates, the size of the ground sample can be varied and different types of foodstuffs can be ground and sampled as compared to a grinder with limited adjustability. The ground sample is distributed to a main discharge chute and a sampling chute with an adjustable valve to provide a selected small percentage of the total ground foodstuff.

Abstract: The contact sensor of the hinged arm of a measurement machine for taking measurements in three dimensions is replaced by a light sensor secured at the same position. A first position-marking axis defined by a light beam emitted by an emitter disposed in a first position is used to determine a first vector by two measured points. The emitter is moved in a plane so as to take up a second position, and a second position-marking axis defined by the light beam of said emitter is used by measuring a point on the second axis. The projection [O.sub.1 ] of the second axis point onto the first position-marking axis is then used to enable a frame of reference [O.sub.1 X, O.sub.1 Y, O.sub.1 Z] to be established.

Abstract: A car bed for an infant comprises a cot body having a generally rigid rim providing support for rigid end portions, side portions and a bottom portion. A U-shaped handle has the ends of its limbs pivotally attached to the end portions of the cot body for angular movement about an axis extending longitudinally above the center of gravity of the cot body, between a position in which said limbs are perpendicular to said bottom portion and a position in which the handle is located to one side of said opening. In use, a seat belt is received in guide formations on the handle. Since the handle is located above the center of gravity of the car bed as a whole, the cot body will rotate as a unit deceleration, so that the bottom portion of the cost body is displaced forwardly in an arcuate path to a forwardly and upwardly inclined position.

Abstract: A child safety harness has a pair of lap straps and a pair of shoulder straps interconnected by an impact pad which comprises an upper portion and a lower portion. Coupling means connects the upper portion to the lower portion in a plurality of alternative mutually overlapping positions so as to vary the distance between the upper edge of the upper portion and the lower edge of the lower portion.

Abstract: A method and apparatus for adsorption and detection of adsorbents or analytes. The method and apparatus can be employed in the field for rapid adsorption of analytes and is particularly useful for detection of mycotoxins. A sample to be analyzed is prepared in solution and placed in a test tube. A tube-like adsorption column having a seal and a valve member is forcefully fed into the test tube to force solutions through the valve member into the columun and through a filter and adsorbent to trap interferences. The semi-purified solution may then be analyzed for the presence of analytes. The column with the purified solution may be further employed with a second smaller adsorption column similarly equipped with a seal and valve member fitting within the first column. In similar fashion the second column may be forced into the first column to expel the solution therein into the second column and through one or more selective adsorbents for different analytes such as one or more mycotoxins.

Abstract: A tubular membrane-tight flow valve features a waisted support body for the membrane which seals against an annular sealing surface at the waist of the support body. This special shape of the support body is effective in avoiding closing hammer. In the preferred embodiment the membrane is made fractionally longer than the waisted support body and this results in extremely quiet operation of the valve.

A planetary grinder is employed having for example three peripheral discharge outlets, two of which are of uniform size and the third of which has a restricted outlet to discharge a test sample, such as 6% of the entire lot being ground. The test sample has been found to have a closely similar composition to the entire lot and can be subjected to analysis of one type or another with confidence of its representative composition.

Abstract: The child-passenger safety restraint for a seat of a vehicle comprises a safety seat positioned on the vehicle seat and a restraining body securable by a safety belt of the vehicle seat, the restraining body being held on the safety seat with its relative height and horizontal position adjustable according to the size of the child seated. The restraining body and the safety seat are attached to each other by a coupling mechanism that includes at least one member adjustable in itself and/or relative to the safety seat and/or relative to the restraining body and securable in a particular position, with whose help the optimum position of the restraining body for safe restraint is adjustable and securable relative to the safety seat and the child.

Abstract: A protective helmet, e.g. a motorcycle helmet has a chinpiece below its visor which defines an air passage with a member behind this chinpiece, permitting air to flow from an opening in this chinpiece uniformly over the interior of a visor to prevent fogging thereof by moisture.

Abstract: Safety apparatus for restraining a seated occupant in a vehicle may comprise a tunnel-shaped body to restrain the lower torso of a large child or an adult, the body providing a base on which a movable chest-restraining panel is pivotally mounted. In the case of a small child, the lower torso restraining means includes an additional seat providing a base, for example, with a separate fixed panel and/or side portions, on which the chest restraining panel is pivotally mounted. The straps at each side of the occupant's body anchor the lower torso restraining means to the vehicle while enabling limited inertial movement relative to the vehicle seat. If the vehicle decelerates suddenly, the occupant's inertia moves the lower torso restraining means away from the seat until the straps are tensioned and act on lever means to pivot the chest restraining panel into its operative position. Either the lever means, or other locking means, may act as a stop to prevent return movement of the chest restraining panel.
