Abstract: A rafter cutting template and guide for laying out each type of roof rafter for a selected roof pitch given the zero pitch length of the rafter. The template includes a body portion and wing means attached thereto. The body portion is shaped so that each end includes the necessary angles so that its edges can be used for marking the plumb cut line, seat cut and tail lines for each of the types of rafters that that end is designed to lay-out for the selected roof pitch. The body portion also includes means for converting the zero pitch length of each type rafter to the actual length for the selected pitch of the roof. The wing means is affixed perpendicularly to the top edge of the body portion and fulfills two functions.

Abstract: A roll stand has a frame and a pair of small-diameter and substantially parallel working rolls defining a workpiece nip. Thus a strip to be rolled passes in a horizontal upstream-to-downstream direction through the nip. Respective pairs of upper and lower upstream support levers have outer ends pivoted on the frame and inner ends downstream therefrom and respective pairs of upper and lower downstream support levers have outer ends pivoted on the frame downstream of the nip and inner ends pivoted on the inner ends of the upstream levers. Respective pairs of journal blocks mounted on the inner ends of the levers support the working rolls for rotation about substantially parallel axes flanking the nip. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls and are rotatable in the frame about substantially parallel axes flanking the working-roll axes and offset therefrom in the direction.

Abstract: The calender comprises a predetermined number of rolls and at least one of the rolls, for example, the outer roll or the lowest roll of such predetermined number of rolls is structured as a tubular roll or controlled deflection roll comprising a stationary roll support member or beam and a roll shell which rotates about the stationary roll support member and is supported thereat. A position sensor determines the position of the roll shell which is regulated with respect to predetermined reference values by a regulating device. A pre-selected number of different reference values for the position of the roll shell are provided and by selecting an appropriate one of these reference values there is achieved the result that different numbers of the predetermined number of rolls are operative while the remaining rolls of such predetermined number of rolls bear against related stops so that their related roll nips or gaps remain open.

A refractory shot barrel is removably positioned in the shot barrel chamber in communication with the molten metal in the heated container, and two refractory insert halves are removably positioned in the gooseneck chamber and coact to define a gooseneck passage at their parting interface providing fluid communication between the outlet of the shot barrel and the inlet of the nozzle.

Abstract: A stack of detachably-connected, individually carryable bags of a plastic material, preferably plastic foil. Each bag has a front wall, a rear wall and an upper bag opening. The bag walls of each bag are provided with centrally positioned punch-out pieces positioned opposite each other adjacent the upper bag opening. The punch-out pieces may be removed by hand to form handle grips. The punch-out pieces of each of the bags in the ones of the bag walls that are on one and the same side of all of the bags in the stack are removed. Uniting the individual bags into a single stack without additional structural members is possible, when the punch-out pieces remaining in the stack and constructed as oblong perforations are interlocked with each other.

Abstract: An installation for processing unlimbed or delimbed trees in a terminal landing comprises a processing unit (14) which is movable on a track (13) running along a storage of unlimbed or delimbed trees (12). The processing unit (14) includes a loading crane (23) for taking trees from the storage (11) and feeding them, butt end foremost, into a processing assembly (24). The processing assembly (24) cuts the trees to logs which are allowed to drop onto a log receiving bed (15) having an inclined plane on which the logs are parallelized with the track (13) and caused to be uniformly directed, whereupon they are transported to a sorting installation by a horizontal conveyor (16) positioned along the lower edge of the inclined plane.

Abstract: A method of reducing the thickness of a slab of metal under conditions that tend to produce alligator defects in the ends of the slab, the method comprising the steps of tapering at least one end of the slab and directing the same into a rolling mill. The tapered end of the slab is reduced in thickness in the mill, the amount of reduction increasing as the tapered end passes through the mill. The slab continues through the mill to reduce the thickness of the same. The end of the slab is again tapered and directed again through a rolling mill, with each of said tapers providing combinations of entry thickness to thickness reduction such that the reduction taken in the area of each taper is in an entry thickness to thickness reduction zone that does not produce alligatoring in the ends of the slab. The remaining untapered portion of the slab is reduced in thickness in the mill in an entry thickness to thickness reduction zone in which alligator formation tends to occur.

Abstract: Apparatus for chunking wood slabs and the like. The apparatus includes a rotary drum mounted on a frame for powered rotation thereon. The drum carries two linear arrays of teeth at diametrally opposed drum positions, the teeth in the two arrays being disposed at alternate, axially offset positions. A notched anvil in the apparatus is mounted on the frame for reciprocating between first and second positions where the anvil is positioned to intermesh with one and then with the other tooth arrays. The anvil is shifted between its first and second positions, in synchrony with drum rotation, by a pair of flanges carried at opposite ends of the drum, parallel to one another and in planes non-normal with respect to the drum's rotational axis, and a pair of rollers mounted adjacent opposite ends of the anvil for engaging the inner surfaces of the associated flanges.

Abstract: In a positioning control device for guiding the side edges of an elongated strip at the entrance into a hot-rolled wide strip finish rolling mill train, guidance feed members are displaced transversely of the rolling direction by piston-cylinder assemblies. Appropriate displacement of the guidance feed members depends on continuously transmitted measured actual values of the strip position within the rolling train which are compared with preset required values. If the width of the strip exceeds a nominal width then large deformation of the strip side edges occurs along with axial reaction forces in the roller supports of the first rolling stand in the finish rolling mill.

Abstract: This invention relates to a dado cutting circular saw arrangement and more particularly to an arrangement comprising a pair of saw blades which are adjustable from a minimum dado width cutting position wherein the blades are juxtaposed relative to a plane perpendicular to the rotational axis of the blades. A cam arrangement adapted to be interposed between the saw blades is employed for selectively adjusting the position of the blades to cut dados of varying widths. The cam arrangement causes the blades to pivot from their minimum dado position, juxtaposed to the plane, about adjacent peripheral pivot points in a manner that selectively adjustably positions the peripheral edges of the blades diametrically opposite from those adjacent pivot points outward relative to the plane and, thus, provide a range of dado cutting widths.

Abstract: A folding and tucking apparatus for a container end closure forming and sealing machine where a pair of oppositely rotating arms, each having a freely rotatable roller mounted on its distal end, are adapted to engage and move a heat-activated, plastic coated carton end closure panel around a score line from a vertical to a horizontal attitude. The result is that, while the rollers thus move the panel, the relative movement between the rollers and the panel is minimal, thereby preserving clean, unmarred surfaces on end panels of cartons which will be characteristically observed by consumers in the marketplace.

Abstract: Process and apparatus for preventing defects in the symmetry of rolled H-beams or I-beams, i.e., a faulty position of their webs (4) in relation to their flanges (5), by correcting such defects in situ. The differential between the torques applied to the upper and lower rolls (1,2) of the rolling stand is determined and compared to a predetermined threshhold value (.delta.). Any excess of the measured value over the threshhold value is eliminated by correction of the elevation of the inlet table of the rolling stand so as to reduce the measured value to below the threshhold value.

Abstract: A wire forming apparatus for making springs with coiled body portions and end loops is modified by providing a digital controlled wire feeding accessory. The accessory permits the normal mechanical feeding of the wire and tooling to be interrupted for desired intervals during the spring forming process thereby allowing digital controlled wire feeding to occur. The digital controlled wire feeding enhances the normal operation of the apparatus by allowing specified lengths of wire to be added to the coiled body portions and/or end loops of the manufactured spring.

Abstract: A method of reinforcing timber beams (15) by fixing sheet metal plates or strips (10) to the top and/or bottom of the beam (15) so that the plates or strips (10) are placed in tension after compression when a load is applied to the beam (15). Teeth (11) pressed out of the plates or strips (10) are fixed into the beam (15) by passing the assembly between pressure rollers or pads (16). The plates or strips (10) may extend over 40%-70% of the length of the beam (15) in the area of maximum deflection of the beam under the applied load to increase the stiffness of the beam by 50%-80%.
