Patent DE-3714771-A1 (DE)
Title: Arrangement of air-conditioning ducts in motor vehicles
Inventor: VOSS WERNER
IPC: B60H1/00
Filed: 1987-05-04
Abstract: In the circulating air operation of a vehicle air-conditioning device, the defroster nozzle for the vehicle windscreen assumes the function of a recirculating air suction opening. A further recirculating air suction opening is provided in the foot space region. The quantitative subdivision - just like the switch-over of the defroster duct to the recirculating-air suction duct according to the invention - takes place via a flap control. The recirculating air suction from the region of the vehicle windscreen improves the air-conditioning of the motor vehicle interior considerably, since by this means a large proportion of the incident solar energy is led away by the shortest path.

Title: Breathing mask for an inhalation device
Inventor: BADEWIEN REINHARD
IPC: A61M16/06
Filed: 1987-06-02
Abstract: A breathing mask for inhalation devices is universally applicable in that an integrally formed attachment for covering the nose and mouth is thin-walled in the nose-covering region and possesses a deforming element. The deforming element is a hinged U clip which is mounted on the outside of the attachment and engages over the nose-covering region. Depending on the pivoting position of the hinged U clip, the thin-walled covering region is deformed, and this permits adaptation of the breathing mask to the shape of the face of the inhaling individual and/or to the mode of operation, namely warm-air inhalation or aerosol inhalation.

IPC: B65B55/06
Filed: 1987-10-08
Abstract: In order to achieve quick and uniform heating-up of the inner and/or outer surfaces of glass vessels to the sterilisation temperature and to cool the vessels again thereafter without the glass breaking, the inner and/or outer surfaces of the glass vessels are briefly brought to a temperature of at least 300@C by means of burners and subsequently cooled again. For this purpose, the burners are repeatedly passed in timed fashion along the inner and/or outer surface, whereas cooling also takes place in timed fashion in several temperature stages by means of cooling air or by means of a cooling water aerosol.

Title: Cooling-bed approach roller table with distributing brake slides for the selective occupation of the cooling-bed rakes
Inventor: DEWES WOLFRAM DIPL ING
IPC: B21B43/00
Filed: 1987-11-06
Abstract: The patent application relates to a cooling-bed approach roller table leading to a rake-type (notch-type) cooling bed, consisting of an approach channel with sloping rollers, an apparatus for braking and ejecting the rolled bars via a sloping slide channel to a distributing brake-slide device which then transfers the rolled bars to the swinging rakes of the rake-type cooling bed, which place the bars in the first notch of the alignment plates of the cooling bed. According to the invention, the slide channel has, as a lateral extension, slide rails arranged at intervals and projecting over the area of the distributing brake slides, for the purpose of guiding the rolled bars ejected from the approach roller table to the distributing brake slides, and the individual distributing braking surfaces are placed in such a way in the area of the slide rails, by stepwise raising of the distributing brake slides, that they can each successively take up one rolled bar conveyed on to the slide rails. Significant advantages obtained are that a device has been created which treats the rolled stock gently, requires little expenditure on maintenance and servicing and requires less input power.

Patent DE-3834717-A1 (DE)
Title: Method for measuring the waviness of a milled surface
Inventor: BENDIG HORST DIPL ING
IPC: G01B7/34
Filed: 1988-10-12
Abstract: A method is proposed for measuring the waviness of a milled surface of a milled workpiece which can be applied as an in-process method. A three-dimensional wobbling movement of the milling cutter which occurs during the milling operation is used to derive an electric measuring signal, for example by extension (expansion, elongation, measurement) on the spindle housing of the milling machine (miller). The signal amplitudes in the case of the milling cutter speed and higher harmonics are estimated from the measuring signal. The signal amplitudes are summed up and the degree of waviness of the milled workpiece surface is determined from the sum of the signal amplitudes using a transfer function specific to the milling machine.

Title: Impression tray for preparation of an impression of a human jaw with teeth
Inventor: SCHREINEMAKERS JOSEPHUS PROF
IPC: A61C9/00
Filed: 1988-11-05
Abstract: Impression tray for preparation of an impression of a human jaw with teeth, comprising a shaped jacket provided with a U-shaped groove cross-section in the region of the row of teeth, the jacket having an edge at the side of the oral vestibule and an edge at the tongue side or on a palatinal edge. On making the impression the shaped jacket is filled with an impression composition having a high viscosity and is pressed onto the row of teeth, so that the edge at the side of the oral vestibule and the edge at the tongue side or the edge palatinal end at the movable mucous membranes of the jaw beyond the active border of the movable mucous membranes. The edge at the side of the oral vestibule and the edge at the tongue side or the edge palatinal are pressed onto the movable mucous membranes. The impression tray is chosen such that the shaped jacket surrounds the associated row of teeth and at the sides the immovable mucous membranes at a clear spacing of less than 5 mm when the edges are pressed onto the movable mucous membranes. At least in the side wall which leads to the edge at the side of the oral vestibule, the U-shaped groove cross-section has perforations which are arranged in the region of the movable mucous membranes. <IMAGE>
Patent DE-3840470-A1 (DE)
Title: Prosthetic components as replacement for the meniscus apparatus
Inventor: LIEKE MICHAEL DIPL ING DR
IPC: A61F2/38
Filed: 1988-12-01
Abstract: The invention relates to a prosthetic component intended as replacement for the natural meniscus and mounted as a buffer between tibia and femur. This component comprises displaceable cushioning elements which have a crescent shape in plan view and a wedge shape in cross-section. The conventional knee joint endoprostheses are predominantly made of relatively hard and unelastic material. In comparison, natural joints are much more resilient. The natural damping properties are largely absent in the conventional endoprostheses. Since the loads that occur in normal everyday use of the joints are nevertheless the same as before implantation of the prosthesis, the loads that occur must be absorbed and buffered at another point in the force flux. The menisci have the task of a dynamic acetabulum; they are intended to distribute the forces that occur over large areas, so that the load on the affected tissues remains within the tolerance limits. As displaceable elastic cushioning elements they increase the elasticity of the joint. The solution according to the invention resides in the fact that the physiologically-anatomically normal menisci are imitated as far as possible; predominantly as regards shape, points of attachment, ligamentous connections, elastic damping behaviour and fine structure - and this, above all, as regards fibres and the course thereof (etc.). This exact imitation results in optimisation of the elastic and ... Original abstract incomplete.

Patent DE-3841548-A1 (DE)
Title: Internal combustion engine
Inventor: HAAS ECKHARD DIPL ING
IPC: F02F1/42
Filed: 1988-12-09
Abstract: In those designs in which the valve axis lies in a plane which runs parallel to the cylinder axis, unevenly formed valve chamfers are produced, which on the lower-lying points of the valve seats form undesirably large clearances, which adversely affect the mixture formation and/or the combustion. The combustion chamber is designed so that the centre point of the resulting spherical surface is displaced from the cylinder axis by the same amount as the simply inclined inlet and exhaust valves from the geometrical centre of the cylinder, so that the axis of the inlet and exhaust valves lying in one plane passes through the centre point of the combustion chamber sphere. As a result geometrically minimised chamfers equal all round are produced on the valve walls. <IMAGE>
