Abstract: A breaker reinforcing tape for belted pneumatic tires, a method of making such tape, and a method of constructing such tires therewith, are disclosed. The tape includes a generally sinusoidally crimped strip of uncured rubber and a plurality of similarly crimped parallel cords having their undulations following and nesting in the undulations of the crimped strip, the cords at successive apexes being secured to successive apexes of the strip. A second uncured rubber strip in a flat condition is secured to alternate ones of the apexes of the undulations of the array of cords and the crimped strip at one face of the latter. At least one frangible element is interposed in a fixed and substantially flat condition between the crimped and flat strips for releasably reinforcing and stabilizing the flat strip against inadvertent expansion that would prematurely reduce the amplitude and frequency of the undulations of the crimped strip and its associated cords.

Abstract: In the disclosed motor arrangement, a single stator operates with one of eight rotors having a number of teeth equal to Z.sub.R = 5u(n + 1) .+-. gu. In the equation, n is one less than the number of teeth on each pole of the stator, u is equal to the number of pole groups, and g is any integer varying from 1 to 4. Energizing the poles of the motor is one of five winding arrangements. The motor, with a single stator, is capable of stepping at one of 40 stepping angles.

Abstract: Machine for making crayons or the like comprising means for supplying fluid material to a series of mold cavities in a horizontally rotatable mold table, means for controlling the temperatures of the cavities, means for ejecting the molding products from the cavities, means for receiving the ejected products and conveying them to one or more delivery points and means for removing excess material from the mold table and recycling it, with suitable controls for operating the several elements according to a desired program and with specific improvements in the apparatus and in the method of operation.

Abstract: An apparatus for a single feeding of an unattended pet out of an initially hermetically sealed can of pet food is disclosed. The apparatus includes an electric motor-driven can opener arranged in a housing, and a presettable timer which operates a switch to close the energization circuit for the motor at the time the feeding is to take place. The can-opening mechanism includes a cutter blade and can-turning gear combination, a vertically reciprocatable slide member supporting the cutter blade and a cam follower, and a power gear and box cam combination driven by the motor for vertically displacing the cam follower. In operation, when the motor is started to effect rotation of the gear, the cam forces the cam follower and therewith the slide member downwardly slightly, so that the cutter blade is forced through the lid of the can at the beginning of the cycle and is then held there while the can turns to sever the lid from the body of the can.

Abstract: A novel two-stage submerged fermentation process for producing vinegar with an acetic acid concentration of more than 15% is disclosed. In the first fermentation stage, the total concentration (i.e. the sum of the alcohol and acetic acid concentrations) increases from a starting level between 12 and 15% to a level above 15%, generally between 15 and 17%, but the acetic acid concentration is not permitted to exceed 15% while the alcohol concentration is maintained between about 1 to 5%, whereby both bacteria multiplication and acidification take place in the fermenting liquid. In the second fermentation stage, the total concentration is maintained constant but the acetic acid concentration is permitted to rise above 15% while the alcohol concentration drops almost to zero, whereby mainly acidification will occur while bacteria multiplication decreases and stops. The second stage is terminated when the desired acetic acid concentration above 15% is reached.

Abstract: An air deflector, which is adapted to be mounted on the roof of a cab of a tractor pulling a trailer and has a frontwardly facing totally curved air deflecting surface that is symmetrical about a vertical center plane and is forwardly convex in all horizontal and vertical cross-sectional planes, is disclosed. To define the deflecting surface, the deflector has a central portion and a pair of symmetrical rearwardly turned wing portions at the opposite sides of the central portion and includes a top edge of substantially circular curvature and a base edge of substantially elliptical curvature.

Abstract: A contact exposure unit having a transparent contact surface and a liquid development unit having means for preventing leakage of a developer are, respectively, constructed as independent units. The exposure unit and the development unit are adapted to be releasably combined with each other thereby to form a portable copier. Outer housings of the exposure and the development units constitute in combination the housing of the portable copier.

Abstract: The single-stage building of 0.degree. belted pneumatic tires completely in flat band form on standard building drums, is disclosed. The feasibility of the process rests on the provision of the substantially inextensible metallic or non-metallic belt cords in the form of longitudinally extensible high "soft stretch" tapes. In a preferred version of the invention, the tape is composed of a plurality of cords each having formed therein a multiplicity of undulations which in any given straight length of the tape are substantially planar, the cords being disposed in side by side relation so that the planes of the undulations of each cord are generally parallel to the planes of the undulations of each adjacent cord, and the cords together with a relatively weak and frangible but only minimally undulated stabilizing yarn for the tape being secured to each other and held in their undulating state by a relative weak, chain stitch knitted, frangible stitching yarn or thread.

Abstract: Aerodynamically profiled ring travelers of generally ear-shaped configuration and designed for movement in only one direction along the inside of a ring of a yarn twister or like machine with minimized aerodynamic resistance and ring to traveler friction, are disclosed. Any such traveler is characterized by transverse cross-sectional configurations which have, as viewed in the intended direction of movement, an oblong shape with a relatively wider or more blunt leading edge and a relatively narrower or less blunt trailing edge, and which further have an airfoil shape in certain sections of the traveler that are so oriented as to cause lift forces to be generated at those sections in opposition to the centrifugal force and, if desired, also the yarn force, acting on the traveler when the same is in use.

Abstract: An electric motor-driven can opener having a push button-operated switch to close the energization circuit for the motor is disclosed. The can-opening mechanism includes a cutter blade and can-turning gear combination, a vertically reciprocatable slide member supporting the cutter blade and a cam follower, and a power gear and box cam combination driven by the motor for vertically displacing the cam follower. In operation, after a can to be opened has been loaded into the cutting mechanism without the lid being penetrated by the cutter blade, the motor is started by depression of the push button to effect rotation of the gear, the switch being held in its "closed" position by a latch even after the button is released. The cam initially forces the cam follower and therewith the slide member downwardly slightly, so that the cutter blade is forced through the lid of the can at the beginning of the cycle and is then held there while the can turns to sever the lid from the body of the can.

Abstract: The processing of uncured rubber or like raw material, which is normally produced, stored and shipped in sheet form but which is to be subjected to a continuous and uniform strip feeding into an extruder, mill or like treating apparatus, is disclosed. For this purpose, there is provided in a sheet of such material a plurality of slits extending across the sheet and spaced from each other longitudinally of the sheet, the slits in an alternating sequence starting at the opposite side edges of the sheet and each terminating short of the respective other side edge of the sheet. When one end portion of the slit sheet is introduced into the bite of the apparatus, the sheet is subjected to a pulling force and separates along the slits into a continuous zig-zag strip. Apparatus for slitting the sheet in the indicated manner is also disclosed.

Abstract: A generally ear-shaped ring traveler, designed for movement with minimized ring to traveler friction and aerodynamic resistance along the inside of a ring of a yarn twister or like machine, is disclosed. The cross-sectional configuration of the traveler at any given transverse plane is characterized by an oblong shape having a relatively wider or blunt leading edge and a relatively narrower or less blunt trailing edge, with the cross-section being airfoil-shaped in the main body section and in each of the upper and lower transverse arms so as to cause lift forces opposing the yarn forces and the centrifugal force to be generated, and generally drop-shaped in the transition regions between the arms and the main body section so as to provide a generally neutral streamlining effect. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: Rivets to be used for securing end connectors to cord-reinforced conveyor belts and having a body with a head at one end and a bore at the other end, are disclosed. To facilitate driving such a rivet through the belt, a sharp-pointed elongated mandrel is loosely fitted at one end of the body thereof into the bore at the end of the rivet and is releasably secured to the rivet body by a strip of adhesive tape. The mandrel body is thinner than and at least as long as the body of the rivet and has a conically flaring portion adjacent the end connected to the rivet. When the rivet and mandrel combination is driven through the belt, the mandrel forms a pilot hole which facilitates subsequent entry and passage of the rivet, and the tape is automatically stripped off as the rivet/mandrel juncture reaches the belt body, so that the mandrel self-releases from the rivet as soon as the bored end of the latter has fully passed through the belt.

Abstract: Generally ear-shaped ring travelers, designed for movement along the inside face of a ring of a yarn twister or like machine and having streamlined cross-sectional contours at all essential transverse planes for minimizing aerodynamic resistance, are disclosed. The cross-sectional configuration is characterized by an oblong shape having a relatively wider or blunt leading edge and a relatively narrower or less blunt trailing edge. The shape may be symmetrical or asymmetrical with respect to a given longitudinal dividing line of the section, and the dividing line may be either generally parallel to the ring or diverging therefrom, as viewed in the normal direction of movement of the traveler, at an acute angle of not more than about 30.degree.. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
