Abstract: A list finder, for example, a telephone index, is provided in which all of the main parts can be integrally moulded of plastic mostly by simple moulds which do not require undercut moulding; the only essential non-plastic parts being a hinge pin pivotally connecting a base and a cover, and a spring. The base has two spaced apart pedestals each of which has laterally spaced upwardly facing and downwardly facing hinge pin seats, with a clear space being provided below the downwardly facing hinge pin seat so that this can be moulded by a unitary mould member which also moulds the underside of the base. The cover includes a planar portion and two downwards projections having a central web and a cylindrically curved flange, the flanges being engageable in T-shaped slots in the sheets of the index. The web member has an upwardly facing hinge pin seat, and an aperture is provided above this seat and the flanges so that these can be moulded by a unitary mould member which also forms the top of the cover.

Abstract: A mill lining is disclosed, intended for e.g. a primary or autogenous mill in the mining industry. The lining comprises shell plates and lifter bars made from elastomer material and mounted in a mill drum. The lifter bars extend substantially in the axial direction of the mill drum and project into the mill drum beyond the inner surface of the shell plates. At least some of the lifter bars, preferably every second, are designed to act as elastomer springs by having a longitudinal recess or slot in their impact front side facing forwardly in the contemplated direction of rotation of the mill drum. The recess or slot is inside the inner surface of the shell plates and serves as a strain concentrator concentrating the tensile strain of the lifter bars to an area relatively unexposed to sliding abrasion of the material being ground.

Abstract: A reinforced bitumen pipe has an inner, strength-providing, reinforced thermosetting resin layer which is coated on its inner and outer sides with a bitumen layer. The bitumen layer on the inner side, and preferably also the bitumen layer on the outer side, is separated from the strength-providing reinforced thermosetting resin layer with the aid of an insulating glass fiber layer into which the thermosetting resin and the bitumen partially penetrate without finding their way up to each other.

Abstract: A device for the treatment of a fluid with magnetic lines of force comprises an elongated non-ferromagnetic outer casing and at least three spaced-apart elongated magnet assemblies positioned therein to form laminar passageways for said fluid. Each magnet assembly comprises at least one tier of at least two permanent magnets encased in non-ferromagnetic jackets and arranged in coaxial line in N--N and S--S relation. The polar ends of the magnets are received in ferromagnetic support members having opposed surfaces to magnetize the support members with the polarity of said polar ends and to distribute the magnetic energy therefrom to the opposed surfaces. The magnet assemblies are positioned so that the polarities of the support members in one of the magnet assemblies are unlike the polarities of the oppositely disposed support members in an adjacent magnet assembly. Means are provided for positioning the magnet assemblies within the outer casing.

Abstract: A transmission unit for coupling the engine of a motor vehicle to either a manual-shift gearbox or an automatic gearbox includes a differential having a crown gear, pinions for coupling the crown gear to the output shaft of the gearbox and a housing for enclosing the differential, the pinions, and either a mechanical clutch or a torque converter. The housing has a first coupling face portion for attaching the transmission unit to an engine, a second coupling face portion for attaching the transmission unit to a manual-shift gearbox or to an automatic gearbox, and bearings supported to engage the pinion and the input and output shafts of the engine, the gearbox and the differential, with the gearbox of either shafts in substantially the same position relative to the housing. The housing can be a one-piece construction or a two-piece construction. A bearing support housing can be utilized with the main housing when coupling the transmission unit to an automatic gearbox.

Abstract: A corner joint formation for pre-shaped building logs of the type in which the flanks of a notch in the top of one log fit against the sides of a neck formed by a notch in another log forming a corner with the first log, wherein the mating side faces of the neck and notch are tapered so as to fit closely together when the logs are fully engaged. The tapered flank faces of the notch stand proud of an outer shoulder which conforms closely to the outline sectional shape of the mating log and forms an interference fit with a similar shoulder of this mating log. The neck of the joint formation is preferably ridged to inhibit flow of water across the joint, and in addition a weather strip may project from the upper edge of the neck ridge to inhibit flow of air across the joint.

Abstract: An apparatus for unloading bulk material from a storage space includes an upward conveyor (14), in particular a screw conveyor. For scraping the bulk material to the inlet end (22) of the upward conveyor (14), there is a scraper conveyor (27, 28) which is pivotally movable up and down and is telescopically extensible. The scraper conveyor is pivotally connected to a protective tube (24) which is rotatable and extends about the upward conveyor (14). The protective tube is located within a pressure-absorbing pipe which prevents the bulk material from impeding the rotational movement of the protective tube. This arrangement makes it possible for the scraper conveyor to remove bulk material from different regions of the storage space, including corners.

Abstract: Longitudinally spaced sections of a collapsible plastic tube are supported on vertically spaced support surfaces. The supported sections of the tube serve as liquid reservoirs, these reservoir sections being laterally supported at their outlet ends by an overflow support. When the depth of liquid exceeds the height of the overflow support, the liquid flows downwardly through an overflow section of the tube into the succeeding reservoir section. Air is heated or cooled by flowing it through spaces which are bounded by the reservoir sections. A solar collector has its inlet connected to the lowermost reservoir section, and its outlet connected to the uppermost reservoir section.

Abstract: A kite-like flying device includes a sail, a keel stick with a larger resilient member at its leading end, and wing sticks connected to the opposide ends of a smaller resilient member the midportion of which extends laterally through the larger member to provide a resilient resistance to forward movement of the keel stick. A cross stick is flexed and received by sockets which are slightly inclined relative to each other in connector blocks slidably mounted on the wing sticks. Two strings extend from the operator to a control rod which is connected by a string harness to the kite. The connectors for connecting the strings to the control rod each include three bores through which the strings pass back and forth to provide on each side thereof a loop and an extending string portion which passes through the loop so as to be frictionally retained when tension is applied to the opposite extending string portion.

Abstract: A plurality of coplanar belt conveyors extend in parallel spaced relationship to each other to feed successive sheets to be stacked into a stacking compartment formed on the conveyors. Just upstream of the stacking compartment, one or more endless belts are loosely engaged about pulleys so as to provide free, deformable loops normally lying crosswise with the belt conveyors. Pressed by each sheet being transported by the belt conveyors, the free belt loops engage the upstream edge of an existing stack of sheets in the stacking compartment and raise same away from the conveyors, thereby permitting the new sheet to be fed under the existing sheet stack. The free belt loops can be subsequently withdrawn from between the sheet stack and the new sheet as the belts are revolved about the pulleys in a specific direction. In another embodiment the belts are nonrotatably supported, and a pullout rod extends through their free loops.
