Abstract: A dual-chamber package comprising a substantially dimensionally stable outer container (1) with a dispensing valve (2) for accommodating liquid or pasty contents and an inner container disposed within the outer container (1) for receiving a pressurized gas such as pressurized air or the like, wherein the inner container (3) is a flexible bag and wherein the dispensing valve (2) comprises a dispensing tube (17) disposed within a valve body (14) for movement from a closed position to an open position and vice versa. To simplify the design, increase the operational safety and attain improved ecological compatibility, the inner bag (3) is connected to the dispensing valve (2) and adapted to be filled therethrough with pressurized gas when the outer container (1) has been filled and closed, so that with the dispensing valve (2) in the open state the contents can be ejected from the outer container (1) while the inner bag (3) expands correspondingly.

Abstract: Apparatus and method for using a compressed gas in an aerosol spray system to produce and maintain an effective aerosol spray includes the use of an aerosol spray valve 4 for emitting the aerosol spray. A dip tube 18 is coupled to the valve 4 and extends into the spray system. The tube 18 has an upper portion which is substantially airtight above an initial liquid level 14. A lower portion of the dip tube 18 extends below the initial liquid level 14 and has a liquid entrance hole 24 substantially at the bottom thereof. A vapor tap hole 26 is provided in the dip tube 18 above the liquid entrance hole 24 and below the initial liquid level 14. The vapor tap hole 26 allows compressed gas 16 to enter the tube 18 and mix with the liquid 20 therein when the liquid level 28 has fallen below the vapor tap hole.

Abstract: An improvement in a sealed pouch made of molecularly-orientable polymeric film that is sealed along peripheral edge margins is disclosed. The pouch defines a sealed cavity for containment of a fluid. The pouch also defines a sealed fluid-discharge spout that is in fluid communication with the fluid cavity. The pouch further defines a seam disposed between the fluid cavity and the spout. The improvement comprises at least three essential features. One such feature is that a portion of the polymeric film which defines a fluid-discharge end of the spout is molecularly-oriented in a preselected direction. Another such feature is that a portion of the seam defines a slit disposed transverse to the preselected direction. Still another feature is that a portion of the sealed pouch peripheral edge margin in the vicinity of the fluid-discharge end of the spout defines a tear-initiating notch oriented in the preselected direction.

Abstract: A device for preparing a very homogeneous and finely divided fine-ceramics mass from ceramic raw materials, liquids, aggregates, and similar materials, whereby the starting materials are finely ground, and liquid is added and later partly removed. The starting materials are ground dry or moist and all or some of the starting materials are first allowed to fall free in and through an upright container while being contacted with all or some of the liquid, which is injected in subject to turbulence, and then agglomerated into a granulate.

Abstract: A method and apparatus for closing or sealing the gap space defined between a tunnel support frame and the ground during the tunneling formation of adits in connection with underground mining operations and the construction of underground tunnels, wherein backfill concrete is introduced into the gap space, comprises the disposition of inflatable bags within the gap space so as to be in abutment with the backfill concrete. In this manner, proper and complete backfilling is able to be achieved whereby the cured backfill concrete will exhibit proper structural integrity. The bags may be fabricated from a suitable plastic foil and are provided with an inflating-deflating valve. The bags can be reused upon subsequent support frame sections as the tunneling operation progresses.

Abstract: Water supply in aircraft for on-board use in conjunction with water outlets in lavatories and a galley, includes a waste water tank connected to at least some of the waste discharge outlets on board of the aircraft; a water purifying plant connected to and receiving water from the waste water tank; and a fresh water tank having outlet means, connected at least to some of the water outlets, and having an inlet connected to said water purification plant, for receiving therefrom purified waste water; an additional tank for drinking water may be provided as well as a separate supply line therefrom leading to drinking water outlets on board of the aircraft.

Abstract: A valve cup for use in an aerosol dispenser is configured to provide an anti-seating feature. In one embodiment, dimples are impressed in the sidewalls of a valve cup to inhibit seating of the valve cup flange on the circular shaped ring around the periphery of an opening at one end of the aerosol dispenser. In a second embodiment, detents are placed on the edge of the flange in which the sidewalls of the valve cup terminate to inhibit the seating of the flange on the circular shaped ring.

Abstract: A railroad track including rails and transversely extending ties. The end portions of the ties are placed on a rigid substructure. For reducing the sound emission, loading members are placed on the ties between the rails. These loading members have an essentially T-shaped cross-section, wherein the horizontally projecting portions are placed on adjacent ties. Sound-insulating elastic inserts may be provided between the ties and the loading members. Consequently, no fittings for fastening the loading members are required. In addition, the space existing between the ties is utilized in an optimum manner by filling it with sound-insulating material.

Abstract: A one piece tamper-evident paperboard carton having overlapped end flaps secured to each other in such a way that the ends of the carton cannot be opened without tearing the paperboard so that observation of the carton would indicate that it had been previously opened.

Abstract: A paperboard carton having a top wall structure with a reinforced handle arrangement for grasping and lifting the carton. The top wall structure and handle arrangement include a pair of overlapping inner and outer panels secured to each other and having thumb and finger receiving openings spaced from each other and separated by three plies of carton material to provide additional strength in the handle area of the carton top wall.

Abstract: A liquid-tight, automatically erectable, self-supported, composite paperboard and plastic tray structure.

Abstract: A tubular carton containing automatically self erecting internal longitudinal and transverse partition structures.

Abstract: A tray having tab, bottom, side and end walls arranged and disposed so that by pushing inwardly on the end walls, a tray will be formed from a flat tubular structure and the end walls will snap into interlocking engagement with the top wall.

Abstract: A six celled collapsible carton formed from a single cardboard blank which includes an automatic locking bottom and dividers which extend the entire height of the box. The carton is provided with four L-shaped dividers, two of which further include a central tab, spaced from both the top and bottom edges of the divider, for fixedly connecting an associated alternate divider to form a pair of cross-shaped divider members. One section of each pair of cross-shaped divider members overlaps to form a central wall. The side edge of each overlapping section is provided with a notch for creating an interengagement between the sections to add structural rigidity to the central wall. The side edges of the overlapping sections further include an arcuately shaped portion above the notches to facilitate the interengagement between the sections. The carton can be shipped in a flattened configuration and can be readily erected.

Abstract: VOR receiver which operates in known manner when receiving from normal VOR ground stations, SSB-DVOR and DSB-DVOR ground stations, and with substantially improved accuracy when receiving ASB-DVOR ground stations. When the receiver receives ASB signals, one sideband is suppressed, and the phases of the half-wave-shaped signals present after demodulation of the other sideband are measured. The azimuth is determined from the measured phase values of each complete antenna cycle by Fourier integration.
