Abstract: A diving and swimming mask, comprising a mask body made of a soft material which has at least one front opening around the eye region, which opening is closed by a transparent member, particularly a lens and there being provided, at each lateral side of the mask, attachment points for attaching an end of a strap and/or a buckle element for engagement of an end of a strap for fastening the mask against the user's face. According to the invention, when worn by the user the transparent member is positioned inclined or may be positioned inclined against the face of the user at the lower edge of the said transparent member, i.e. at the edge nearest to the user's mouth so that the upper edge of the transparent element is nearer to the user's face at the said lower edge, than at the opposite upper edge of the said transparent element.

Abstract: A corner support element for paving slabs has stackable plate elements to facilitate transport and for height adjustment. The guide and support elements for corner parts of paving slabs, namely plate elements, have cruciform upright support and distance providing projections. The projections are shaped as upwardly tapering elements with open cavities downwards for accommodating corresponding underlying projections. The elements are modular and can be separated along radial rows of projections to form semicircular segments for supporting two adjoining slab corners or quarter segments for supporting only a single corner. The elements are stacked in columns without turning each of the modular parts mutually between them.

Abstract: It is an age-old problem that with time finge-rings can become difficult to remove, while in general they should not, after all, be all too easy to take off. With the invention there is provided an openable ring which, it should be noted, does not comprise irritating hinge parts or releasing means, in that the one of the four geometric main elements of the ring is configured as a substantially straight piece which can be turned outwards from the natural plane of the ring, while in the turned inwards position it is in snap-lock engagement with the opposite end of the remaining, substantially U-shaped ring element. For this releasable locking, use is thus made of the natural elasticity of the ring element, and it is the whole of the outwardly-pivotal piece in itself which is used as the operating element for the opening and closing of the ring.

Abstract: A drilling machine 1 with a drill pipe holder 10 to be operated automatically in boring as well as in pulling, disposes over a gripper 20, which is constructed rotatably about an axis 21 and beyond that also axially displaceably, and has a telescoping support arm 22. The pipes 8, 9 can be arranged, i.e. stored, inserted into one another in pipe depositories 11, 12, 13 forming a partial circle 15 and can also be pulled out of them and swiveled into the drilling axis 7 with the aid of the gripper 20. When pulling the drilling string, the pipes 8, 9 can then be individually fanned out into the pipe depositories 11, 12, 13 and then later on the outer pipes 8 can be slid over. The entire process is operated automatically with the gripper 20.

Abstract: The invention relates to a coating system in the form of a vehicle (3), which can travel in a pipe (1) or a duct. The coating system is pulled over an appropriately stabilised section of piping (4) in such a way that the inner wall (58) can be evenly coated by a rotating distributor (18) with an outlet opening (29). The various product and supply lines (20, 21, 22, 136) are securely accommodated inside the section of piping (4) by means of a highly resistant flexible tube (138) into which they are drawn. Said flexible tube is air-tightly sealed by covers (148, 149) or a terminal block (150) at the ends and is also configured to absorb tensile forces. The individual supply and product lines (20, 21, 22, 136) are thereby protected in the section of piping (4) without being subjected to excessive pulling or other forces. They are also prevented from interfering with each other.

Abstract: A pipe fitting element comprises a tubular fit-in sleeve (1) which can be fitted into an end of a pipe (2) to be connected, and a clamping ring nut (10), coaxial to the sleeve (1). The pipe (2) is arranged to be clamped by tightening the ring nut (10) on the sleeve (1) and translating it towards the pipe (2) while drawing two clamping surfaces (5, 13) mutually closer. One of the surfaces is situated on the outer surface of the sleeve (1) and the other situated on the inner surface of the ring nut (10). These clamping surfaces (5, 13) consist of progressive widening (105, 113) of the outside diameter of the sleeve (1) and of the inside diameter of the end of the ring nut (10) turned towards the pipe (2). A pipe joint, which has at each end a pipe fitting element of the above described type is also provided.

Abstract: The new Ground Fault Detection and Diode Fault Detection (GFD/DFD) Systems have rotating and stationary component assemblies. The rotating assembly has four interface modules, which are normally encapsulated, in a specially configured support ring. The GFD/DFD Systems support ring assembly is bolted to the brushless exciter. The brushless exciter is attached to a generator or motor. The GFD/DFD System support ring is provided power by an induction loop antenna attached to a stationary Induction Power Supply (IPS). A Receiver Control Unit provides power to the IPS and receives and conditions the RF (radio frequencies) data transmitted from the GFD/DFD System support ring assembly. These units together provide the means to detect ground faults, to detect diode faults, and to activate alarm lights and electrical control signals for normal and faulty operating conditions.

The invention is preferably used in connection with conveyor chains, in particular by the production of foodstuffs by freezing temperature.

Abstract: The invention concerns a tool for regulating the surface pressure on a blank constituting a metal plate which forms the starting item for shaping a finished item in a press. The blank is placed between a draw ring (23) and a blank holder ring (24). Besides, the tool comprises a shimming plate (1, 5, 10) provided with chambers (2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14) which are delimited by the shimming plate itself and by a flexible membrane (27). The shimming plate is placed between a tool bottom part (17), alternatively a tool top part (16), and the blank holder ring, alternatively the draw ring. A pressure medium like hydraulic oil may be led to the chambers. Thereby it is possible locally and individually to increase the surface pressure on the blank depending on the number of chambers, the design of chambers and the location of the chambers in the shimming plate. Furthermore, it is possible to regulate the pressure during the shaping process itself.

Abstract: An efficient method of cleaning various workpieces is the so-called wet blasting, by which the workpieces are exposed to a spraying of water with a content of hard macro particles. Optimally, this blasting medium should be recirculated, but this implies noticeable problems with respect to separation of cleaned-off dirt and worn-down blasting particles. The invention provides for a system for processing units enabling these problems to be overcome in a relatively simple manner for achieving a high efficiency and low costs of the combined system.

Abstract: The invention provided for a conveyor belt wherein chain links are assembled such that eye parts are inserted into the intervals between two eye parts in the opposite chain link, whereafter the transverse rod according to the invention is inserted from one side of the conveyor belt through the overlapping openings in both chain links. When the notches provided on the transverse rod adjacent the head portion come into contact with the end face of the chain link, i.e. the side of the chain link, the notches can be brought into engagement with slits provided in the outmost chain link by twisting the head portion and pushing it into the end portion of the chain link. When the notches are engaged in the slits the transverse rod is fixated such that it will not move sideward in relation to the longitudinal direction of the conveyor belt.

Abstract: The mixed oxide WxMo1-xO3, where preferably x can be in the range 0.01 to 0.9, is very useful for the detection of oxidizing gases and in particular is superior for the detection of ozone. The preferred composition is in the range of 1% to 21% Mo (i.e. 99% to 79% W). The present example in which the composition of the sensing material is in the range WxMo1-xO3 with x varying from 0.01 to 0.9, is clearly distinct from the device claimed in applicant's earlier patent. Precipitation of the material as a mixed oxide from an aqueous solution of the ammonium metallates in concentrations of the appropriate stoichiometric proportions yields a powder that can be screen-printed to give an ideal microstructure. Resistivity of the material may be tailored to a desired value by adjusting the Mo/W ratio within the single phase field. Varying this ratio adjusts catalytic properties of the material.

Abstract: A system of two fuel ampoules that can deliver a reactant by diffusion through one of the ampoule walls to the other, such that when said reactant enters the second ampoule, it reacts with another reactant in said second ampoule, making hydrogen gas as a product. Both ampoules are stored in a fuel impermeable container. These ampoules used with small low power fuel cells which need a steady controlled uniform delivery of vaporous fuel such hydrogen and alcohols. This fueling system provides a simple safe fuel interactive system for small hydrogen fuel cells that prevents inadvertent hydrogen production by any single ampoule being exposed to water or typical consumer environments.
