Title: Steel support member for buildings - is protected from fire by having cross=section with hollow spaces filled with protective material inside gas-tight bags held in position
Inventor: MARZOUKI TAIEB
IPC: E04B1/94
Filed: 1991-09-18
Abstract: A support member is used for a building, and partic. a frame member for a steel construction hall with columns, beams etc. which are pref. steel sections with a recess or hollow space in their profile; the columns and/or beams have fire-protective filling in those recesses/spaces. The filling is pref. enclosed in a gas-tight plastic film laminate of polyethylene/aluminium foil/polyester construction. The figure shows the cross-section of an example with an H-type profile. This has the two outer faces (15) and the connecting webs (16); between the webs (16) there are thus rectangular-section spaces (17) along the complete length of the members concerned. To provide the construction with fire protection it contains fire-protective material (18) inside a covering. The covering used is held in position by a double-sided adhesive strip (27) which keeps the filling on to the webs (16) when the members are being erected. The open sides are also covered (19) with a U-section cap which fits (21) on. ADVANTAGE - The products have fire protection which is simple, inexpensive and, above all, it itself protected from external factors. (Dwg.4/9)

Title: Stabilising aids for surfboard teaching
Inventor: PLAESIER RICHARD
IPC: B63B35/79
Filed: 1993-01-25
Abstract: The conventional surfboard is converted into a teaching board by strapping buoyancy aids (4, 5) to each side of the board near the mast fitting. The increased support prevents the board from capsizing during teaching. The buoyancy aids are secured by straps and can be removed to return the board to its original state.The buoyancy aids can be inflatable for a compact storage. The amount of buoyancy is adjustable to follow the progress of the pupil. This is achieved by separate buoyant shapes attached by the straps.

Patent DE-4307002-A1 (DE)
Inventor: BEATER PETER DR
IPC: B60T1/08
Filed: 1993-03-05
Abstract: During braking of a vehicle with a hydrostatic propulsion drive, an adjustable hydraulic motor (4) of the hydrostatic propulsion drive is adjusted in the direction of the greatest possible capacity and the kinetic energy of the vehicle is partly directed into a prime moved (1) and partly dissipated by pressure limiting valves (7, 8) in the closed working circuit of the hydrostatic drive. When the rotary speed of the prime mover (1) exceeds a limit during braking, the capacity setting reached by the hydraulic motor (4) is maintained, or the capacity is fixed at a defined level, until the rotary speed has dropped below the limit again. Then, the adjustment of the hydraulic motor (4) in the direction of the greatest possible capacity is continued. The capacity of the hydraulic motor (4) is set by a control pressure, and the control pressure is reduced to increase the capacity of the hydraulic motor (4) when braking. The control pressure is influenced when the rotary speed of the prime mover (1) exceeds the limit by a braking torque limiting device (B) operative according to the rotary speed of the prime mover (1). A modification (Fig 4) has a shuttle valve with two in lets in the motor control circuit. In a further modification (Fig 5), the spring side of a pressure limiting valve in the control circuit is additionally acted upon by pressure upstream of a measuring orifice. <IMAGE>

Title: Device for automatically controlling the incidence of light into a room
Inventor: KOESTER HELMUT DIPL ING
IPC: E06B9/264
Filed: 1993-04-01
Abstract: The invention relates to a device for automatically controlling the incidence of light into a room. This device has a plurality of similar light-guiding profiles which are arranged one on top of the other and consist of three reflecting (aluminised, silvered, metal-coated) and concavely domed surfaces. At least the underside of a deflecting profile has two reflecting surfaces, of which one surface is directed outwards and the other surface is directed inwards. The light-guiding profiles are miniaturised such that they can essentially be circumscribed by a circle having a diameter of 10 mm. The dazzling effect caused by direct incident solar light is thereby greatly reduced. In addition, the light-guiding profiles are arranged between two rows at such angles that the incident sun beams are reflected, at a steep angle, to the ceiling or to the floor of an interior space, while the reflection of these beams towards the outside is likewise deflected steeply downwards. <IMAGE>

Title: PWR fuel element lifetime extension - by inversion of fuel rod bundle after certain operating time
Inventor: NYLUND OLOV DIPL ING
IPC: G21C3/334
Filed: 1993-04-23
Abstract: (A) extension of the fuel element lifetime in a PWR is effected by the following steps, not necessarily carried out in the given order, (a) after a preset operating time, withdrawing the fuel element (1) from the reactor core, the connectors between the element lead (6) and one end of the control rod guide tubes (4) and between the element foot (7) and the other end of the control rod guide tubes (4) having compatible designs; (b) detaching the control rod guide tubes (4) from the head and the foot; (c) placing the fuel rod bundle (2) on the head (6) and connecting the ends of the guide tubes (4), which were previously connected to the foot (7), to the head (6) and vice-versa; and (d) introducing the fuel element (1) into a suitable location in the core, the foot (7) being at the bottom as previously. (B) Also claimed are similar processes and appts. for carrying out the processes. ADVANTAGE - Inversion of the fuel bundle, usually carried out after 3 operating cycles, provides more uniform corrosion along the fuel rods so that fuel element lifetime can be extended by 4 to 5 operating cycles.

Title: Production method for a storage space which is formed from an adhesive-free region of a label and a container surface and is fastened in a permanent manner on said surface by means of the adhesive regions of said label and is intended for storing an enclosure leaflet or the like, which can be achieved by means of an enclosure-leaflet supply device, a pressing-on device and a labelling machine
Inventor: LASKOWSKI SIGISMUND
IPC: B65B61/20
Filed: 1993-07-27
Abstract: The invention relates to the production method for a storage space which is formed from an adhesive-free region of a label and a container surface and is fastened on said surface by means of the adhesive regions of said label and is intended for storing an enclosure leaflet or the like, which can be realised by means of an enclosure-leaflet supply device, a pressing-on device and a labelling machine. As has been shown in practice, the conventional, folded enclosure leaflets are still the best and the most cost-effective means of information, which are used extensively, in particular, in the pharmaceutical and chemical industries. They are cost-effective and environmentally friendly and user-friendly. A single problem is posed by the storage space and its production method in order to store the enclosure leaflet in a secure, economically viable and user-friendly manner, since, for financial and environmental reasons, the future aim is to dispense with a folded box. This object is achieved according to the invention in that the folded enclosure leaflet is positioned on the surface of the container by means of an enclosure-leaflet supply device. <IMAGE>

Title: Dust-tight connection of transportable bulk goods containers which for their part have a sealing-off device
Inventor: LESK ADOLF
IPC: B65G69/18
Filed: 1993-08-31
Abstract: Dust-tight connection of transportable bulk good containers which for their part are provided with a sealing-off device, in that the discharge funnel of the container dips into a docking device which is provided with a rubber disc which for its part has a hole which is smaller in diameter than the discharge funnel. As a result, the rubber disc nestles in a dust-tight manner on this discharge funnel. Located in the discharge funnel there is a sealing-off cone with a ring whose lower edge, during closing, first cuts off the goods flow and then finally seals off the outlet at the oblique part of the discharge funnel. By using a second, smaller ring on the cone, a dust-tight sealing-off of the discharge in accordance with the same system as above is achieved via a further rubber ring.
