Title: Lifting gear to lift railway cartridge for maintenance - continuous track, and pairs of lifting appliances with supports for individual wheels
IPC: B66F7/00
Filed: 1991-06-08
Abstract: The installation is for railway vehicles. It has a track (10), extending continuously through it, and lifting appliances (30), located in pairs on either side of the track. These have projecting support (31), each formed to support a wheel, and moveable between raised and lowered positions. Additional supports hold a raised vehicle on the chassis/body, independant of the other supports. In the area of the lifting appliances, the rails (11, 12) have a profile, to support and guide the wheel flanges without help by the tyres. The rails are of width, so that the tyres project outwards over the rail edges. The wheel-supports are positioned close by the outer rail edges, when in lowered position. When raised, they support a wheel on its tyres.

IPC: B01D29/23
Filed: 1991-08-08
Abstract: A connecting adapter for filter candles having a tubular filtering part and a connecting sleeve arranged at one end of the tubular filtering part allows individual filter candles to be removed from and inserted into a filter candle package. The connecting adapter has a flat cylindrical base body (1) with a circumferential surface (2) having a first (2a) and a second (2b) steps. The diameter of the second surface step is smaller than the diameter of the first step, but is at least equal to, if not larger than, the largest diameter of the tubular filtering part of the filter candle. Sealing elements (4) are arranged on the first surface step and locking elements (5) are arranged on the second surface step. The locking elements lock the connecting adapter in the reception opening of a mounting plate and do not project beyond the first surface step. The connecting adapter with the filter candle can thus be inserted and secured into the reception opening of the mounting plate. It is not necessary to dismount the filter candle package.

Title: Monolithic refractory lining for aluminium melting furnace - contains aluminium oxide, silicon di:oxide and calcium oxide
Inventor: LE ROUX JOHAN HEINDRICH
IPC: C25C3/08
Filed: 1991-12-13
Abstract: Monolithic refractory lining for an Al melting furnace consists of 40-100% Al2O3; 0-60 SiO2 and 0-3% CaO. The fired coating has a max. thermal expansion coefficient of 7 x 10 power-6/deg.C.

Title: Rotary absorber for conversion of solar rays to heat energy - consists of hollow drum or column without base or cover rotating on its long axis in stream of hot air
Inventor: COST KARLFRIED
IPC: F24J2/04
Filed: 1992-03-02
Abstract: A number of drums (5) are exposed to the rays of the sun (1) and rotate on their long axes. Hot air flows through and around them (4).

Title: Application of dissolved polyurethane to plastic and glass vessels - enhances strength to permit weight reduction, lower cost manufacture and transport
Inventor: RANSMANN HEINZ
IPC: C03C17/32
Filed: 1992-03-05
Abstract: In a process to coat glass or plastic bottles with plastic, the novelty is that the bottle or other vessel is first coated with a polyurethane polymer dissolved in an aromatic or aliphatic-based solvent which is allowed to harden with heat if required. The bottle is dunked in the soln. one or more times and polymerisation takes place at 230 deg.C. and the coating is allowed to harden at between 180 and 230 deg.C.. USE/ADVANTAGE - The process facilitates the application of a plastic coating to glass vessels. The plastic so applied greatly improves the surface finish and in partic. the ability to withstand high pressure by sealing the so-called Griffith fractures. Further, the bottle wt. can be reduced by a half with no loss of strength, to reduce mfg. and transport costs. The resulting plastic coating resists scratching and adheres very well to glass surfaces.

Filed: 1992-06-17
Abstract: A method for manufacturing a package, a device for manufacturing the package, a package and a part for such a package are described. The package is preferably a blister package which consists of a cardboard back plate (11) and a plastic film hood releasably connected to the latter. The cardboard back plate (11) contains recesses, through which projections (20) of the film hood pass. The projections (20) have a floor section (26). The cardboard back plate (11) and the film hood are joined in such a way that the projections (20) pass through the recesses and project above them in sections.
