Abstract: First and second tabs are affixed to the surface of a body in close proximity with each other and in partially side by side relation. First and second optical fibers are affixed to the first and second tabs, respectively, and are movable therewith. The optical fibers are positioned transverse to the tabs and in alignment about a mechanical quiescent point in the absence of strain in the body. A source of light produces and directs light through the first and second optical fibers. A light detector detects light transmitted through the first and second optical fibers and determines the intensity thereof, which is proportional to the magnitude of compression and tension strains in the body.

Abstract: As a substitute for brazing conventionally employed for attaching curved pad holders to rims of an eyeglass-frame, casting is used for formation of an eyeglass-frame including, in one body with its rims, straight pad holders which should thereafter be bend to a required configuration. Conventional troubles arising from use of brazing are fully removed.

Abstract: For forming a fluid tight removable connection between a high pressure tube and a sleeve, an olive is sealingly secured to an end portion of the tube by electromagnetic forming. Then a nut is threaded on the sleeve for deforming the olive and forcing it sealingly against an internal face of the sleeve. When the olive is at least partially of electrically conducting material, it is shrunk onto the tube by magnetoforming after a removable forming die has been inserted into the tube.

Abstract: A projectile for a centerfire cartridge that achieves maximum energy transfer with limited target penetration when fired from snub-nosed pistols. A hollow point lead bullet is provided with an aluminum jacket of sufficient hardness to avoid fouling the pistol barrel and which allows the cartridge containing the projectile to feed reliably in auto-loading pistols and yet does not restrict normal expansion of the bullet upon impact with the target. The jacket extends into the nose recess of the bullet and covers the peripheral portion of the bullet base, whereby the jacket is securely fastened to the bullet and separation subsequent to impact is prevented. The jacket is uniformly notched at the nosetip annulus to weaken the aluminum jacket and promote upset at surprisingly low impact velocities.

Abstract: A ribbon blender for a development station of an electrographic copier/duplicator is formed using a plurality of flat blanks stamped from a strip of sheet material. Each blank has three substantially concentric rings joined by two spaced strips. The outer ring and the middle ring are cut to form ribbon segments and then the segments are bent out of the plane of the blank. A plurality of the resulting bent blanks are assembled on a shaft alternately with spacers to form a ribbon blender. The free ends of the ribbon segments of adjacent blanks are in substantially end-to-end alignment to joints form ribbons.

Abstract: In a method for automatically attaching successive fly strips to a continuous slide fastener chain, the successive strips are fed to a standby point one after another by a conveyor horizontally spaced from a sewing machine by a gap in which the standby point is disposed. A preceding strip is supplied from the standby point to the sewing machine with its trailing end portion hanging in the gap, while a succeeding strip is kept waiting at the standby point for a subsequent supply. When the trailing end of the preceding strip has passed a fixed point downstream of the standby point in the gap as the sewing of the preceding strip progresses, the succeeding strip is supplied at a speed higher than the rate at which the sewing of the preceding strip progresses.

Abstract: The ballast box of a power mining shovel is coupled to the rotating frame by two pins installed through orifices in parallel plate projections extending from the ballast box and corresponding eye projections on the main rotating frame. In addition, the feet of the gantry rear legs are pinned through second orifices in the same parallel plate projections from the ballast box such that the force generated down the center of the longitudinal axis of the gantry rear leg is coupled through the centers of both of the orifices in the parallel plate projections.

Abstract: A method of forming a connection between a tubular member and an annular collar which has at least one internal annular recess. The method includes positioning the collar over portion of the tubular member to define an axially extending connection zone embracing the annular recess, positioning a solid deformable transmitting material in the tubular member in alignment with the connection zone, confining the transmitting material axially to the connection zone, and applying a deformation force gradually to the transmitting material to deform its radially outwardly and thus deform the tubular member into the recess of the collar to form a connection.

Abstract: A swaging mandrel is inserted in a tube confined by a tube sheet or other surrounding structure. A pair of seals define the axial limits of a hydraulic pressure zone within the tube sheet in which radial expansion of the tube takes place in response to fluid pressure. At the secondary side of the tube sheet, an elastomeric ring extends beyond the tube sheet and, in response to the fluid pressure, produces an attenuated radial expansion force that bulges the tube to produce a tight seal at the tube sheet surface and a positive mechanical interlock between the tube and the tube sheet.

Abstract: The disclosure relates to a slat alternation apparatus in a machine for the manufacture of venetian blinds and the like, for optional alternation of slat belts (2-6) of different colors during the manufacture of a venetian blind, a magazine (1) with a number of different slat belts (2-6) being laterally shiftable at the infeed end of the machine, for positioning of the desired slat belt (2-6) in a position for infeed into the machine.

Abstract: A curved slide fastener chain and a method for producing a curved slide fastener are disclosed. The curved slide fastener chain comprises a pair of fastener tapes and a plurality of fastener element rows planted on each of a pair of the fastener tapes. Each of the element rows includes a straight and a curved inter-engagement portion. The curved inter-engagement portions are dis-inter-engaged while the straight inter-engagement portions are inter-engaged, so that each of the pair of fastener tapes are able to extend in a straight line. Therefore, deformation of the curved inter-engagement portions due to heat and tension applied thereto during the washing, dewatering and drying steps in producing a curved slide fastener can be prevented.

Abstract: The method starts with bringing the stack of slats to be assembled into a standby position. The slats are then removed from the bottom of the magazine and stepwise provided with connecting elements having hooks which are then engaged with loops provided on carrier strips of the shutter. Thereupon, the hooks are bent to close and the slats are moved downwardly by steps. After suspending the last slat, the carrier strips are cut through above the last slat, so that on a conveyor provided below, the assembled shutter forms a stack to be removed. This process is continuous, so that in immediate succession, the assemblage of a further shutter begins.

Abstract: A pair of separable slide fastener stringers is fed along in one plane along parallel spaced paths, respectively, toward throats of a Y-shaped guide channel in a slider fixed in position. Pins of the stringers are inserted into the guide channel through the throats, respectively. The pins as they emerge from a rear end of the slider are stopped when rows of coupling elements start intermeshing with each other within the guide channel. The separable slide fastener stringers are moved again at the same speed to bring the rows of coupling elements into intermeshing engagement.

Abstract: A cam follower shoe for a fuel injection pump is constructed to hold captive the roller of the cam follower. Two shoes are constructed at the same time from a single block of material which is bored to produce a bore and is then divided into two parts by a pair of cuts which extend axially crossing from one side of a diametral plane to the other, the plane being normal to the direction of movement of the shoe in use. At one end of each shoe the surface subtends an angle of less than 180.degree. but at the other end of the shoe when the cuts are straight, the surface subtends an angle of greater than 180.degree..

Abstract: In a method of and apparatus for forming element-free spaces in a continuous slide fastener chain at ends of successive fly strips sewn to the slide fastener chain, the chain having a pair of intermeshed rows of coupling elements, portions of the intermeshed rows of coupling elements to be removed are detected by a sensor assembly disposed at a fixed position spaced a first distance upstream from a gap-forming device before such portions arrive at the gap-forming device. The sensor assembly first determines whether the longitudinal extent of a space provided between the confronting ends of an adjacent pair of the fly strips is larger than a predetermined distance, and then on the bases of the determination, controls the feeding of the chain and the operation of the gap-forming device so that the element-free spaces can be provided accurately at the ends of the respective fly strips regardless of the spacing between adjacent fly strips.

Abstract: In a method and apparatus for the height adjustment and installation of a slidable and/or raising, rigid roof member, to be built into a roof opening of an automobile roof, which roof member, after its height adjustment, is screwed to elements of the roof construction which do not participate in the height adjustment movement, a rapid and reliable height adjustment and installation are achieved in that, first the actuating elements are moved into the closed position, whereupon the roof member is inserted, by means of an installation template engaging over the roof opening and to be positioned onto the automobile roof, into the roof opening in a defined position with pressing of the roof member front edge onto the associated roof opening edge and simultaneous height adjustment, whereafter finally the screwing of the roof member in this position takes place.

Abstract: A method and a device for attaching a rail on a timber support. The device includes a helically threaded fastener adapted to be screwed into a helically threaded borehole in the support after a rectangular metal insert is positioned in a rectangular opening at the periphery of the borehole. The borehole is sufficiently large that the fastener only contacts the timber support via contact with the insert. The rectangular opening is longer than the insert so that there is radial play between the insert and one end of the insert. The other end of the insert is adapted to contact a sloped side of the thread of the fastener. As the fastener is screwed into the borehole, the sloped side of the fastener presses the insert parallel to and perpendicular to the screwing axis of the fastener. As a result, the insert elastically expands parallel to and perpendicular to the screwing axis. Because the expansion perpendicular to the screwing axis is less than the radial play, no radial forces act on the timber support.

Abstract: A process is provided for the construction of a composite tube comprising a metal tube, in particular a tube of copper, and a cladding of tubular form into which the said tube is inserted, the material of the said cladding being constituted by a deformable foam material, in particular foam rubber, characterized by the fact that it comprises at least a first phase in which a section of said cladding of predetermined length is disposed in a configuration with its axis substantially rectilinear, a second phase in which a fluid under pressure is fed from a first end of the said cladding to the interior thereof, while at the other end there is introduced one end of the said tube in such a way as to cause, by the action of the said fluid under pressure, a radial deformation of the said cladding, and a third phase in which the said copper tube is introduced axially into the interior of the said cladding while it is deformed radially.

Abstract: A two component cartridge case which may be of dissimilar materials including a tubular casing component with a mouth for receiving a projectile and reduced diameter shank with male threads to be received by the base component with corresponding female threads, recessed pocket on its centerline for holding a primer and a flange for engaging a firearm extraction mechanism.The components, both tubular casing and base, are carefully proportioned to allow only a minimum of the base to enter a sizing die during sizing operations thus permitting ease of sizing using conventional (ordinary) sizing dies, while using a hard material in the base component for added strength.The components are shaped to permit manufacture of the tubular casing component from existing conventional cartridge cases or from specially headed two diameter cartridge cases.
