Title: Ventilation system for buildings - introduces cool air in summer and warm air in winter from natural sources to condition the room air
Inventor: BISPING FRANZ
IPC: E04B1/76
Filed: 1990-10-13
Abstract: The ventilation system for buildings conducts cool air from the cold side of the building to the interior of the room during the warm months.

Title: Fast and sensitive photodiode integrated with other circuits - features an etched trench in which the optical fibre is placed and pin-diode opposite the end of the fibre
Inventor: RICHTER RAINER
IPC: G02B6/42
Filed: 1990-10-17
Abstract: The photo-diode consists of a cathode (10) and an anode (11) contacting highly doped semiconductor regions, and an area of high resistivity for charge generation (9).  The semiconductor (3) is pref. Si.  The diode features at least on 2 sides vertical, or nearly vertical, parallel surfaces formed by trench walls.  Light enters the diode through one of these surfaces, pref. from an optical fibre which has a thickness equivalent to the depth of the trench and is contained at a right angle to the diode surface.  The diode wall next to the fibre pref. has an anti-reflection layer or layers, pref. a Si-dioxide/-nitride double layer.  The region between the surfaces of the diode has surface layers, pref. more highly doped than the generation region and pref. of opposite type on the 2 sides, electrically connected with at least one electrode. Also claimed is the use of a MOS-structure, without heavier doping than the generation region and a metal or pref. polysi electrode, instead of at least one of these layers. USE/ADVANTAGE - The diodes have high sensitivity because of the use of highly doped material for the detection part together with a high drift field.  The use of reflecting layers increases the apparent thickness of the region without requiring a high biasing voltage to maintain field strength, improving also the spectral response.  The lowly doped region, e.g. 2x10power 14 cm-3, used for generating charge carriers can be integrated with circuits such as differential amplifiers with good yield on large area wafers because of the use of epitaxy.  The diode has a low capacitance and therefore a short reaction time.

Title: Composite filter material - uses separate suspensions held apart during water extraction until their edges bond and then all water is drawn out
Inventor: HOFMANN HANS
IPC: B01D39/18
Filed: 1991-02-22
Abstract: To produce a filter felting material with differing filter performance, especially for wrap-around filter plugs for deep filtration, at least two different watery suspensions are used.

Title: High strength hot plate pressure butt welding of plastics profiles - by pinching molten flash after welding with blunt blades and forming upset material back on either side of the weld
Inventor: DILL GEORG
IPC: B29C65/20
Filed: 1991-09-21
Abstract: Plastics profiles are first welded by thrusting together the heated ends with free displacement of material to form flash. After a time delay, but before the flash solidifies, blunt knife-like blades are forced together, close to the outer surface of the profiles, leaving a small gap (m) for the flash, and forcing back the `upset' material either side of the weld flush with the original surface contour. This operation is completed during the time in which the material viscosity in the centre of the weld is less than that towards the inner surface,, so that the latter part supports the material displaced by the blades. The inner, unseen, surface is undistrubed. ADVANTAGE - Improves compaction of weld material. Increases weld strength but with min. finishing. Improves weld appearance and avoids sink marks
