Patent DE-3144578-A1 (DE)
Title: Seal arrangement having two seals
Inventor: JEDAMZIK ERWIN
IPC: F16L23/18
Filed: 1981-11-10
Abstract: The invention relates to a seal arrangement having two sealing faces which form a seal gap and two seals arranged in series at a distance from one another in the seal gap. The invention relates especially to a flange seal arrangement. The seal gap has a width (s) which increases from the outer edge of the sealing faces towards the inner edge of the sealing faces as a result of deformation. This gap width varies by an amount ( delta  s) in the region of the installed seals. A control hole is connected to the interspace. In order to ensure that neither of these seals becomes leaky, one of the seals is designed as a hard seal and the other as a soft seal. The hard seal is provided as the main frictionally engaging seal and operates as the main frictionally engaging seal in the entire range of variation ( delta  s). The soft seal is in secondary frictional engagement, which is determined by the hard seal. The hard seal has a modulus of elasticity within the range of 10<4> to 10<5> N/mm<2> and the soft seal has a modulus within the range of 10<2> to 5 . 10<3> N/mm<2>. <IMAGE>

Title: Centre punch tool for the assembly of double-lobed pipe clamps
Inventor: BREMERICH MARTIN
IPC: B25D5/00
Filed: 1982-05-07
Abstract: The centre punch tool for the assembly of pipes by means of double-lobed pipe clamps permits accurate locating of the dowel holes to be drilled for attaching the pipe clamps. The tool consists of a centre part with transverse part and has a recess of the size of the pipe diameter, as well as two centre punches which are arranged at an angle of 90 DEG  to the centre axis of the recess and thus of the pipe to be laid. The centre punches are at a distance from one another which corresponds to the hole spacing of the pipe clamp. The device is pushed with its recess over the pipe, in the course of which the centre punches touch the wall or ceiling surface. By a light blow on the handle of the centre punch tool, the centre punches mark the holes to be drilled, so that the drilling machine can be accurately positioned.

Title: Device for the arranging of profile piece goods, preferably U-profile glass, in a way suitable for loading
Inventor: GOTTSCHALK HEINZ
IPC: B65G57/08
Filed: 1982-06-11
Abstract: The invention relates to a device for the arranging of profile piece goods, preferably U-profile glass, in a way suitable for loading. The aim and object of the invention is an effective solution to the transfer of profile piece goods from longitudinal conveyors to loading equipment, reduction of transport distances and improvement of working conditions. According to the invention the object is achieved by means of a positioning device and swivel device, to which an accumulator device is assigned, and a transport device between said positioning device and accumulator device. Especially U-like profile piece goods, lying in the starting position with the web on the roller conveyor, are transferred to the accumulator device such that in their final position they lie on the flanks, in multiple rows of two. The device is provided primarily for careful handling during the arranging of relatively sensitive profile piece goods and/or profiled piece goods made of non-magnetisable material in a way suitable for loading. The device is especially suitable for profile glass with U-like cross-section and larger profile lengths. Furthermore use is possible for rolled, pressed or bent profiles of breakable or unbreakable material.

Title: Tube assembly system for empty tubes and lighting tubes
Inventor: DIECKMANN DIETER DIPL ING
IPC: F21S2/00
Filed: 1982-06-24
Abstract: The invention creates a tube assembly system for empty pipes and lighting tubes, for the construction of exhibition stands and shops, and their fitment with shelves, tables, cloakroom stands, supports for advertising media, lighting systems, railings, seating furniture, cabinets and the like, in which the tube ends can be connected by means of two-piece plug-in pins which can be expanded by means of hollow-headed screws which are inserted into the two pin halves and can hence be clamped into the tube ends. In order that no holes need to be provided in the ends of the tubes to be connected, and to allow the tubes to be arranged such that they are protected against rotation before assembly, the pin is surrounded by two half-shells which have an external tooth system which can be latched into a corresponding internal tooth system on the tubes, and both half-shells have an external ring which, in the assembled state of the plug-in pin, is located between the tube ends and has a hole for actuating a hollow-headed screw which is inserted into the two pin halves.

Title: Method of reducing abrasion in static conveyor systems and conveyor system
Inventor: BEHRENS RALF
IPC: B65G53/52
Filed: 1982-11-26
Abstract: This invention is for use in the conveyance of very abrasive materials. Unlike other wear-reducing systems, this method permits wear of the actual side of the conveyor system. When this side has been penetrated, the conveyed material enters a pocket mounted outside, above the point threatened by wear. There is almost no forward movement in this pocket, and so the solid materials which have penetrated are deposited and halted. They form a layer which very quickly reseals the side which has been penetrated by abrasion. The new side of the conveyor system produced in this way regenerates itself. The conveyor system implementing the method has at least one pocket outside areas which are threatened by wear, which may also contain pronged inserts to impede forward movement and to improve deposition of the solid material. In addition, the invention describes a tube as a conveyor system, the pockets of which are formed by segments of tube and are closed at the joints of the tubes by a subsequent application of sealing caps. Conveyor systems as defined by this invention bring about a considerable extension of the period of time between replacements and therefore a reduction in the costs arising from repair work and loss of production.

Title: Elements for use in landscaping
Inventor: DOSE GEORG
IPC: E04F13/08
Filed: 1982-12-03
Abstract: Purpose: plants which hardly climb, or non-climbing plants, can be grown on any façade or fronts. Novel aspects in architecture, landscape architecture and gardening are opened up. Particularly suitable for sloping and steep areas. Solution: soil, together with additives and if desired seed, is enclosed between plastic sheets or in boxes, either loose or shaped into raised beds. The sides, or recesses, in the plastic sheets and boxes are slotted or perforated so that water can penetrate from the outside and the plants can grow through these slots or perforations without this resulting in too great an evaporation of moisture. This principle has a great range of variations, for example large raised beds in individual pockets, quilted mats, transparent webs containing individual, small raised beds, and transparent long webs containing a large number of small raised beds of soil, if desired on both sides, or interconnected fillings divided in a sausage-like manner, or like strings of beads, in the form of hanging columns to be covered with a vegetation on all sides and equipped with an internal irrigation hose, or boxes in the shape of letters, and the like. They are attached by means of clamps, hooks, nails, screws, behind tensioned wires, behind lattices, by means of ropes ... each variation being different. Fillings: 1. Container: 2. Slots: 3. Knotted rope as support: 5. Multi-armed support: 6. Plastic sheet: 7. Image, middle: Slots, possible original size. <IMAGE>

Title: Deflection unit for a digital light deflection device
Inventor: WENDT KLAUS ING GRAD
IPC: G02F1/01

Abstract: A deflection unit for a digital light deflection device comprises an alternating series of birefringent prisms and electrode pairs which project into a hollow body made of an insulating material, for example glass, which is filled with a polar liquid such as nitrobenzene. In order to keep the leakage current between the electrode pairs via the liquid at a stable low value during operation, the electrodes are coated with a layer of an ion-exchanging material. The ions occluded in this material act as a Faraday cage and prevent metal ions originating from the electrodes entering the nitrobenzene. <IMAGE>
