Title: Fire-retardant door leaf or window sash, and process for the production thereof
Inventor: SCHROEDERS THEO
IPC: E06B5/16
Filed: 1993-06-29
Abstract: A fire-retardant door leaf or window sash comprises a metal frame (1) and a laminated insulating glass pane (2). The metal frame (1) is assembled from two pieces which are formed from metal plates (3 and 4). L-shaped border strips (5) of one metal plate (3) and U-shaped border strips (6), which enclose the latter, of the other metal plate (4) form the connection of the metal plates (3 and 4), from which, in this manner, a flat box is produced. A cutout adapted to the dimensions of the laminated insulating glass pane (2) is provided in said flat box, with the result that all that remains of the sheet-metal box is the metal frame (1), which is filled with mineral fibres (9) covered by gypsum-plasterboard strips (8). Finally, the metal frame (1) is completed on its inner side, which is located opposite the laminated insulating glass pane (2), by a closure profile (9). <IMAGE>

Title: Process for the work-up of used plastics or mixtures of used plastics for use in refineries
Inventor: GEBAUER MANFRED DR
IPC: C10G9/00
Filed: 1993-09-01
Abstract: Used plastics were to be worked up in such a way that products containing no functional groups are obtained which can be mixed into the petroleum intermediates in an improved manner in the bypass in refineries without separation phenomena. The used plastics or mixtures of used plastics are degraded in an extruder under shear forces and at elevated temperature, a progressive temperature profile up to 475 DEG C being set up to 2/3 of the effective extruder lengths and subsequently a degressive temperature profile being set in the remaining 1/3 of effective extruder length, so that the temperatures at the extruder end are between 280 and 380 DEG C. From 10 to 50% by weight of an asphalt-free petroleum product are metered in there, and homogenisation in a static mixer having >/= 4 baffles is carried out.   The procedure can be carried out internally directly in a refinery or externally, in which case granules are produced which are metered into the refinery plant feed stream via a melting and metering unit. The products obtained are easier to handle, and the number of operational interruptions is significantly reduced through the use of used plastics.

Title: Determination of optimal exercise effort corresp. to desired pulse rate - using neural network or multi-variable analysis in modelling of relationship for evaluation of measurements from successive exercises
Inventor: MARUO KATSUHIKO
IPC: A63B24/00
Filed: 1993-11-15
Abstract: The method for determining the optimum effort corresp to a desired heart rate involves using a bicycle ergometer (1) with two pedals (2), a saddle (3), handlebars (4), a pulse ratemeter (5) and a pedal effort regulator (6).

Inventor: KONDO TOMOHARU
IPC: B01J35/02
Filed: 1993-12-14
Abstract: A honeycomb heater includes a honeycomb structure, a front end (16) and a back end (17), including a plurality of passages which are defined by partition walls and extend in an axial direction of the honeycomb structure, the honeycomb structure being electrically conductive, whereby fluid flows through the passages from the front end to the back end. Electric current is applied to the honeycomb structure to generate heat. Gaps (14) for obstructing flow of electric current extend through the partition walls from the back end (17) toward the front end (16) but do not reach the front end so that a front region of the honeycomb structure heats more quickly than a back region, and a catalyst composition loaded onto the front region is activated earlier. Slits 12 may extend between the front end and the back end. The heater may be used in a catalytic convertor as a preheater for controlling automobile exhaust emission. <IMAGE>

Abstract: A method is disclosed for uniform doping of polycrystalline silicon (30) with hemispherical grains, independently of the other layers of the semiconductor substrate (10). A semiconductor substrate (10), in which a silicon dioxide layer (20) is formed on top of a polysilicon layer (15), is provided in a chamber. A doped rough silicon layer (30) is formed in situ on the silicon dioxide layer (20). This is done by applying the silicon layer (30) on top of the silicon dioxide layer (20) and exposing the silicon layer (30) to a source gas, a doping gas and energy, this being preferably in situ, in order thereby to form a uniformly doped silicon layer and a roughened polysilicon layer (30), for which purpose fast thermal chemical vapour deposition techniques or a chemical vapour deposition carried out at low pressure can be used. As an alternative to this, a uniformly doped roughened polysilicon layer (30) is formed in situ on top of the silicon dioxide layer (20). This is done by applying a layer (30) of amorphous silicon on top of the silicon dioxide layer and by roughening the layer (30) of amorphous silicon in situ. The roughening is carried out by vacuum thermal treatment of the layer (30) of amorphous silicon with the use of fast thermal chemical vapour deposition techniques or a ...

Inventor: ALEFELD GEORG PROF DR
IPC: F25B17/08
Filed: 1994-10-27
Abstract: A cold or heat pump has a two-stage circuit running between three pressure levels (p1 to p3). Cold is delivered at one temperature (t1) and heat at three other temperatures (t2,t3,t6), with heat absorbed at two more temperatures (t4,t5). A single-stage circuit works between two other pressures(p4,p5) and delivers cold at a temperature (t7) that is no greater than the first cold delivery temperature. This also delivers heat at two other temperatures (t8,t10) and absorbs heat at a different temperature (t9). Both circuits are connected by a cascade circuit and at the temperature (t10), heat supplied by the single-stage circuit is used to drive the two-stage circuit at the temperature (t4).
