Title: Glass facade or glass roof with drainage for hollow rebate spaces remaining between the rebates of the glass sections
Inventor: BAUERSACHS GERHARD
IPC: E04B2/96
Filed: 1987-02-06
Abstract: Under some circumstances, water can penetrate into the hollow rebate spaces (103), remaining between the rebates of the glass sections (12), of the roof or of the facade. Up until now, this water has been channelled away, if need be, by outwardly directed openings. In the case of roofs with a gentle inclination, additional water can, however, penetrate through these openings. According to the invention, the rebate spaces (103) are drained via lines (104, 5) on the inner side of the plane of the glass, the invention preferably providing that the said lines, just as the rebate spaces (103), are closed off in an essentially air-tight manner with respect to the inner side of the plane of the glass and communicate with the outer side of said plane, with the result that the same air pressure prevails in the said lines and in the rebate spaces (103) as on the outer side of the plane of the glass. Consequently, an otherwise possible pumping action in the region of leakage points on the outer-side seals of the glass section (12) as a result of air-pressure differences is avoided. <IMAGE>

Title: Process and device for storing, feeding and unwinding film rolls for/on a machine for the surface lamination of panel-shaped wood workpieces
Inventor: LANGMANN HEIKO
IPC: B65H16/06
Filed: 1987-06-29
Abstract: Process and device for storage, feeding and unwinding film rolls for/on a laminating machine. The film rolls have hitherto been accommodated in a complicated manner by means of bars in the unwinding station and the film roll changing is labour-intensive and time-consuming. In addition, the film rolls not required are deposited at any location and are thus not immediately readily accessible and require a long transport distance. Damage-free provision, rapid feeding over a short path of the respective film roll to the unwinding station and simple and automatic accommodation in the winding station are to be achieved. This is achieved by means of a magazine (4) receiving a plurality of film rolls (2) in a readily accessible manner, a gripper (5) moving the desired film roll (2) and by the clamping cone (8), receiving the film roll (2) in an automatically centred manner, in the unwinding station (7) (Fig. 2). This process and the device are suitable for an efficient operation for lamination machines. <IMAGE>

Filed: 1987-07-10
Abstract: In known bucket tappets of the said type, the pressure chamber is sealed off by means of diaphragms of elastomer materials, essentially flexible in an axial direction. Here the short service life, caused by high temperature differences and the large number of components, proves disadvantageous. In order to guarantee sealing of the pressure chamber (7) over a long service life, the diaphragm (8) of the new bucket tappet (1) is composed of a relatively deformation-resistant plastic. The bucket tappet is suitable for the timing of valves in internal combustion engines. <IMAGE>

Patent DE-3730093-A1 (DE)
Inventor: GAECHTER BERNHARD F DR
IPC: G01C15/00
Filed: 1987-09-08
Abstract: In order to acquire and compensate for turbulence effects when determining the direction between a target and a measurement station, a wave radiation with at least two selected frequencies is emitted. The incidence angles of both selected waves are measured practically at the same time at the measurement station. The difference between both measured angular values is then calculated, and on the basis of that difference the angular deviation between the apparent and the real direction of the target is calculated by means of a given algorithm. With this process, short-term non-homogeneity variations of the refractive index of a dispersable medium can also be taken into account when determining the direction of a target. Very precise and corrected angular measurements can thus be carried out very quickly, for instance in a matter of seconds, even in the presence of strong turbulences of the medium along the measurement section extending between the measurement point and the target.
