Abstract: MANIFOLDS FOR INTERNAL   COMBUSTION ENGINE        ABSTRACT OF THE DISCLOSURE         A manifold for an internal combustion engine comprises a plurality of body parts each formed as an inte-gral casting by pressure casting.  A first body part has a mounting flange for the manifold, a plurality of open channels communicating with respective apertures in the mounting flange, and a water  chamber communicating with a port in the flange and a further port in the first body part.  A second body part overlies the channels so that the first and second body parts define a plurality of gas conduits effecting communication between the apertures and a common orifice.  The first and second parts are sealed together along opposed side faces adjacent their outer peripheral edges.  The seal along oppos-ing sides allows access to the joints from the exterior of the assembly, permitting connection by electron beam welding or an adhesive, since all the joints are located on the exterior of the assembly a smoother interior surface is preserved and visual inspection of each joint is possible as it is made.

Abstract: ABSTRACT OF THE DISCLOSURE Electrically-conducting particles may be separated from mixtures thereof containing non-conducting particles by conveying the mixture through a magnetic field oriented angularly with respect to the path of conveyance.  The magnetic field induces magnetic poles in the conducting particles, causing them to deflect from the path of movement of the mixture as they attempt to move in the angular orientation of the magnetic field.  The non-conducting particles are unaffected, so that a separation may be achieved.  The invention is applicable to a wide variety of materials, such as ores or tailings which contain desired electrically-conducting particles, such as, iron oxide, and unwanted gangue constituents.

Abstract: ABSTRACT            A system intended for the transport and storage of product carriers, comprising a plurality of elongated transport units, adapted to be connected to each other so as to form a transport network. The transport units comprise a frame with carrier rollers for the product carrier and an elongated transporting screw provided with driving members, the threads of which are adapted to cooperate with engagement members provided at the bottom side of the product carrier in such a manner that upon operation of the screw the product carrier is advanced along the transport unit, the transporting screws being driven in such a manner that they are always started and stopp-ed in a predetermined position of the transporting screw. By means of a computer apparatus counting and registering the number of revolutions of the transporting screws a permanent and exact control of the position of each product carrier in the system is made possible The engagement members of the product carriers may be formed by ridges, spaced mutually along the transporting screw with the same cross-sectional thread profile as the thread groove of the trans-porting screws, said rims each meshing with the transporting screw during the transport.

Abstract: ABSTRACT OF THE DISCLOSURE     A tube-and-plate heat exchanger comprises a plura-lity of plain tubes intended for one of the heat carriers to pass therethrough, which tubes are arranged in paral-lel rows and are received in broachod holes of cooled plates. In cross section the plates are pro-filed so as to form, in the flow direction of another, for example, gaseous heat carrier, continuous symmetric wave line, thereby forming a passage of undulatory shape for the gaseous heat carrier to flow therethrough. Projections and depressions of one plate face respective projections and depressions of another adjacent plate, thereby for-ming continuously alternating divering-converging sections of passages. The projections and depressions of the cooled plates mate with rectilinear sections which have the same angle of inclination to the axis of symmetry of the cross-sectional wave line, ranging from 8 to 45 deg.          The bending radius at the mating place  of projections and depressions is not more than twenty times the thick-ness of the cooled plate material. To ensure good ther-mal contact between the plain tubes and the cooled plates, which is obtained by sintering, edges of the broached holes are formed throughout their surfaces around the periphery of each tube. The heat exchanger of the in-vention, intended for use as a water-air cooler, is smal-ler m size and weight, being, all other conditions equal, highly resistant to contamination, preventing air-suspended particles of dust and dirt from penetrating to the air space thereof.

Abstract: ABSTRACT OF THE DISCLOSURE    A deskewing document transport device delivers individual documents one at a time into the nip of a pair of pickup rollers.  The documents are gravity fed from an angled panel into the nip.  A curved guide finger is positioned near the bottom of the angled panel and confronting one of the pickup rollers in order to form a curved gap which causes the docu-ments to curl slightly as they approach the nip.  A horizon-tal table is positioned under the curved gap so that, if the document is skewed, the leading edge of the curled document is lightly pressed against the table for deskewing the docu-ment as it passes through the gap.  The inventive transport device is particularly well-suited for use with a microfilm-ing camera.
