Abstract: A hose clip which comprises a flexible strap adapted to be placed around a selected portion of a hose and to be tightened around such selected portion by turning a bolt or screw. An elongated concavo-convex strip-shaped resilient insert is adjacent a portion of the internal surface and extends in the circumferential direction of the strap opposite the mechanism which serves to increase or reduce the effective length of the strap. The convex external surface of the insert is biased in a direction away from the adjacent portion of the internal surface of the strap by one or more springs which are disposed between the insert and the strap and are of one piece with the insert. At least one end of the insert is slidable along the strap. The spring or springs ensure that the strap does not become loose as a result of aging of the material of the adjacent portion of the hose.

Abstract: A coupling for pipes having confronting ends with conical or flat outwardly extending flanges utilizes an elastomeric sealing ring which is placed between the flanges and a variable-diameter clamping device which is positioned to surround the flanges and has two radially inwardly divergent sidewalls each of which is adjacent the exposed side of one of the flanges. The conical radially inner portions of the sidewalls engage and penetrate into the external surfaces of the pipes in response to a reduction of the diameter of the clamping device, and any further reduction of the diameter entails a movement of progressively larger parts of radially outer portions of the sidewalls into engagement with the exposed sides of the adjacent flanges to bring about radial compression of a large portion of the sealing ring.

Abstract: A press platen, for bonding ends of a conveyor belt, having both heating and cooling means, the heating means being electrical resistance elements positioned in grooves bars, within the platen, which bars also define cooling channels therein.

Abstract: The non-profiled end portions of two pipes can be coupled to each other by a ring-shaped band which has at least one axially parallel gap and circumferentially extending corrugations defining two outer chambers and at least one median chamber. Each chamber is open toward the peripheries of the pipes and each outer chamber surrounds a different pipe. Such outer chambers contain arcuate safety devices with radially innermost portions in the form of claws serving to penetrate into the material of the respective pipes when the band is tightened around the end portions of the pipes by a clamping unit which is designed to reduce the width of the gap. The median chamber of the band confines a deformable annular insert which has marginal sealing lips and serves to establish a seal between the internal surface of the band and the peripheral surfaces of end portions of the pipes when the clamping unit is actuated to reduce the diameter of the band.

Abstract: A disposable syrup package for use in a post-mix beverage dispenser including a collapsible bag for containing the syrup; a discharge spout extending from the bag; and a break-away proportioning insert in the spout, which is broken when a dosing valve assembly is attached to the spout. The package structure substantially precludes the refilling and reuse thereof.

Abstract: In a device (1) with a plug portion (2) and a socket portion (3) for the detachable connection particularly of the ends of high-voltage transmission lines and of the ends of low-voltage control lines, and with a mechanism for fixing the connection to prevent unintentional separation, a solution is to be provided through which the manipulation of such a coupling (3) is simplified and, particularly, a device (1) of the above-described type is made suitable also for voltages exceeding 500 volts. This is achieved by constructing the fixing mechanism as a drive element (8) which moves the device portions (2,3) relative to one another into the coupled and uncoupled positions and which locks them in the coupled position.

Abstract: Method and device of automatically controlling the drying process of a laundry drying system until a given desired degree of dryness is reached, including heating means, a drive for the drying system, a control device for controlling the drive and heating means, and means for supplying system-related fixed data concerning the drying of particular laundry, which includes determining the gradient of rising temperature in the drying system during a given early phase of the drying process, calculating a required operating time for the heating means and the drive from the determined gradient and the system-related fixed data, and feeding the calculated operating time as an input to the control device.

Abstract: A low-voltage circuit breaker has a fixed contact and a movable contact which is attached to a pivoted contact carrier. Between the contact carrier and the movable contact, a contact pressure spring is arranged, which is designed as a coil compression spring. The contact carrier has an arm which extends to the vicinity of the contact-making end of the movable contact. The arm carries a setscrew which is positioned to act centrally with respect to a contact overlay of the movable contact. The setscrew limits the lifting of the movable contact or the contact overlay to the desired small extent, when a large current flows through the circuit breaker and exerts electrodynamic force on the movable contact.

Abstract: There is provided a continuous process for the production of water free or substantially water free peralkanoic acids with 2 to 4 carbon atoms by reaction of aqueous hydrogen peroxide with an alkanoic acid having 2 to 4 carbon atoms in the presence of acidic catalyst at a mole ratio of hydrogen peroxide to alkanoic acid of 0.5 to 30:1, preferably from 0.
