Abstract: A solar heat system is comprised of a panel or bank of heat collector modules each of which has a fluid-carrying tube of an elongated triangular shape in transverse cross section formed with longitudinally extended inwardly projected heat radiating fins. A tube is mounted within a concavo-convex reflector of a hyperbolic form such that the side walls of the tube are subjected to reflected rays of solar radiation over an effective range of solar exposure of about one hundred and fifty (150.degree.) degrees. The reflected rays are concentrated in a longitudinally extended focal zone on each side wall of the tube and these zones of concentrated solar radiation move transversely of a side wall in response to the angle of the solar rays falling upon the reflector.

Abstract: A sealing device for a receptacle such as a heavy cloth bank bag for containing money or currency in which a single strip or band of material formed of metal or plastic is stamped with projections or serrations extending from one side of the band and wherein a pair of locking projections in the form of raised panels are stamped in the material near one end of the band, so that the other flat end thereof may be inserted through slits formed by the stamped panels, whereby one or preferably more of the serrations are engaged and locked by the edges of the panels when the strip is tightened around the neck of the bag. Movement of the ends of the strips are thereby prevented in a direction which would unlock the seal but is freely permitted in the other direction for the extent of the serrations so that a tight seal may be accomplished.

Abstract: An open end type of slide fastener has an end stop comprising a pair of lugs formed from a plastic material and secured to the longitudinal edges of respective stringer tapes, each lug having an oblique inner edge extending divergently with respect to the longitudinal axis of the fastener such that the lugs define therebetween a substantially V-shaped opening complementary in shape with the diamond of a slider. One of the pair of lugs has at least one projection continuous to the oblique inner edge and the other lug has a recess receiving the projection. The projection extends transversely beyond the central longitudinal axis of rows of interengaged fastener elements and is disposed for abutting engagement with the slider diamond. When the diamond moves past the projection and spreads the lugs apart, the uppermost opposed coupling elements become disengaged to allow smooth movement of the diamond therebetween.

Means are provided for circulating a lubricating fluid between the rotating sleeves and the shaft.

Abstract: Tubular knitted high pile fabric of indefinite length is formed in a novel manner so that after walewise split lengths of the tubular fabric are coursewise seamed together to form an indefinite length of flat high pile fabric, the seam can be so formed that the flat fabric is able to pass through the fabric finishing apparatus without damage to the apparatus by the seam and without special control of the apparatus to permit the seam to pass therethrough. The novel tubular knitted high pile fabric is specially formed with the pile omitted at walewise spaced courses thereof to form walewise spaced bands of non-pile fabric, and the seam is then formed in the non-pile fabric.

Abstract: A coupling ring is bonded onto the opposite ends of a ferroelectric stack ving substantially the same thermal expansion coefficient as the stack. A thin film of silicone compound is wiped onto the axially exposed surfaces of the rings and surfaces provided in a head and a tail mass are configured to mate with them. A plurality of microspheres are mixed uniformly through a liquid adhesive and this mixture is coated onto the suitably shaped surfaces on the head and tail mass. A stress rod reaching between the head and tail mass axially compresses the ferroelectric stack and excess adhesive mixture is squeezed from between the mating surfaces. The thickness of the liquid adhesive is restricted to the diameter of the microspheres to ensure a high impedance match and upon applying the proper amount of heat, rigid joints are set up between the now hardened adhesive and the head and tail mass.

Abstract: A process for bonding together into a composite structure parts having different coefficients of thermal expansion by use of an adhesive which cures at a curing temperature different from the use temperature at which the structure is to be used, including the steps of applying the adhesive in an uncured state to the parts, then affixing the parts together rigidly at the use temperature to form the composite structure prior to during the adhesive, then curing the adhesive at the curing temperature while keeping the parts affixed together and simultaneously permitting the composite structure to change shape in accordance with the different coefficients of thermal expansion of the parts, the latter step being accomplished by holding the composite structure in a fixture which includes clamping plates which prevent twisting and buckling of the composite structure as its temperature is changed and in which the clamping plates are mounted so as to permit them to shift position to accommodate the bowing of the compos

Abstract: Several courses of random width, low-grade tapered wood shingles are stacked in an elongated trough with the butts of shingles of adjacent courses disposed at opposite sides of the trough to form a substantially continuous stacked shingle lay-up. A cutoff saw consecutively cuts loose packs of shingles from an end portion of the lay-up. After each pack-cutting operation, the lay-up is shifted lengthwise of the trough to a position for the saw to cut another pack from the lay-up. Each severed pack is banded about its center to form a bundle, moved lengthwise partway through a gang saw to form a set of parallel kerfs spaced apart uniformly widthwise of the bundle and extending from an end of the bundle almost up to the band and then turned end-for-end and moved lengthwise partway through the gang saw to form another set of kerfs extending from the other end of the bundle almost up to the band. The kerfs of the two sets of kerfs are in registration.

Abstract: A metal rivet, a two-piece rivet assembly, and a joint including the assembly. The metal rivet includes a preformed head at one end of a solid shank. At the other end there is a tubular upsettable portion which is circularly cylindrical with a recess which terminates at a base opening at said other end of the solid shank. The tubular upsettable portion is so proportioned as to form a proper upset head. At least a part of a core pin fits in the tubular upsettable portion and is retained therein after the rivet is set. During setting it prevents internal buckling of the tubular upsettable portion, and after setting it reinforces the upset head to prevent rollout as a consequence of axial separative forces. As an optional feature, at the terminal part of the forming of the upset head, the core pin can be pressed against the base to swell the solid shank and create a closer, or even an interference, fit for the shank in a workpiece.

Abstract: A method for manufacturing flexible Nb.sub.3 (Al,Ge) multifilamentary superconductive material in which a sintered porous niobium compact is infiltrated with an aluminum-germanium alloy and thereafter deformed and heat treated in a series of steps at different successively higher temperatures preferably below 1000.degree. C. to produce filaments composed of Nb.sub.3 (Al,G3) within the compact. By avoiding temperatures in excess of 1000.degree. C. during the heat treatment, cladding material such as copper can be applied to facilitate a deformation step preceding the heat treatment and can remain in place through the heat treatment to also serve as a temperature stabilizer for supeconductive material produced. Further, these lower heat treatment temperatures favor formation of filaments with reduced grain size and, hence with more grain boundaries which in turn increase the current-carrying capacity of the superconductive material.

Abstract: The present invention provides an apertured circuit board having self-locking terminals which partially cover at least some of the apertures.
