Title: Sealing strip for sealing gap-shaped intermediate spaces between the outside of window frames and adjoining masonry
Inventor: SCHMIDT HANS
IPC: E06B1/64
Filed: 1983-03-26
Abstract: A sealing strip for sealing gap-shaped intermediate spaces between the outside of window frames and adjoining external masonry consists of a profiled body which can be fastened on the rear side to the outside of the window frame and is provided with a front sealing lip opposite the external masonry. On its rear side, which is to be turned towards the outside of the window frame, the profiled body is provided with a locking and sealing lug which extends essentially parallel to its front sealing lip and which can be clamped firmly in the gap between the outside of the window frame and the masonry. Mounting is in this case very simple, as special fastening means, e.g. adhesive, are not necessary. At the same time, the sealing effect is increased so that high heat-insulation and sound-insulation values are achieved.

Patent DE-3319179-A1 (DE)
Title: Optical fibre system for, e.g., motor vehicle rear lamp groups
Inventor: SCHICK JOACHIM DIPL PHYS
IPC: G02B6/42
Filed: 1983-05-21
Abstract: The invention describes an optical fibre system for, e.g., motor vehicle lamp groups for producing powerful light signals in groups of different lamp bodies made from simple plastic parts which are connected by means of one optical fibre in each case via relatively long distances to a central light source in a light-distributing housing. The light of the central light source is fed into the optical fibres with the aid of optical systems such as, e.g., lenses or mirrors in the light-distributing housing. Optical shutters operated electrically or mechanically are used to interrupt the light flux at will, specifically independently of the other light fluxes. The central light source requires only one power line. By contrast, only light signal lines are required for the electrical operation of the optical shutters. As a result, heavy wiring harnesses and power switches are saved. The light source can be a commercial bulb, a halogen vapour discharge lamp, a rare gas lamp, a mercury vapour discharge lamp, a laser or another conventional lamp. Its light is introduced into the optical fibres either simultaneously or in rapid sequence. The inventor thus provides a novel and cost-effective method designed, in conjunction with low weight, for lighting up at little cost many illuminating elements which are easy to produce, and for repairing them or extending their number as required.
Patent DE-3326475-A1 (DE)
Title: Method for setting the wavelength of the zero crossing of the chromatic dispersion of compensated monomode fibres by rounding the refractive index profile
Inventor: TROMMER GERT DR ING
Filed: 1983-07-22
Abstract: The invention relates to a method which permits exact setting of the wavelength of the zero crossing of the chromatic dispersion of compensated monomode fibres to be carried out without placing strict requirements on the manufacturing tolerances. According to the invention, in a first operation a monomode fibre is produced in such a way that the compensation of the material dispersion by an oppositely directed waveguide dispersion leads to a zero crossing of the resulting chromatic dispersion which is at a wavelength slightly shorter than the desired wavelength. After a possible application of protective lacquer, a method which is suitable for controlled rounding of refractive index profiles is used in a subsequent operation to round the refractive index profile (homogeneously over the entire length of the fibre) until the wavelength of the chromatic dispersion zero crossing has shifted towards longer wavelengths onto the desired value, and this can be monitored by measuring during the rounding process, or else after the method has been terminated in the event of quantitative stipulation of the process parameters in order to influence the refractive index profile.

Title: Hydraulic three-way continuous valve for block fitting
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B11/08
Filed: 1984-03-09
Abstract: A hydraulic three-way continuous valve (10) for block fitting is proposed which is more universally operational by virtue of an integrated control function (27) and pressure areas (19, 28) of different size on the control spool (12). At its end located opposite the consumer connection (16), the control spool (12) has a piston section (18) which forms an enlarged pressure area (19) as well as a control edge (27) connected between two control connections (23, 26). Upon activation of the continuous valve (10) via a 4/4-way proportional pilot valve (39) with a spring-centred safety position (55) in which the control-oil feed to the continuous valve (10) is chocked via a first choke point (62) to a lesser extent than the simultaneously effective, considerably choked control-oil discharge via a second choke point (63) and during simultaneous pressure protection by a pilot pressure-control valve (66), the maximum brake pressure can be limited in the fail-safe case and full relief of the hydraulic motor can be controlled. An OR element (45, 47) permits the control-oil supply in normal operation and in the fail-safe case. <IMAGE>

Title: Control device for delaying an unhooking mechanism of a safety belt for vehicle occupants
Inventor: PATRIZZI OSVALDO
IPC: B60R22/32
Filed: 1984-06-22
Abstract: The automatic unhooking of the belt (2) takes place by means of a striking pin (9) loaded by a spring (10). The spring is connected to a plate (15) by means of a cable (11). The tensioning of the spring (10) is guaranteed by a spiral cam (17) connected positively to a wheel (19) which can be actuated by hand by means of a key engaging into a polygonal hole (23) of the hub (19a) of this wheel. The connection between the cam (17) and the plate (15) is reversible, and therefore the spring (10) tends to rotate the wheel (19) by means of the plate (15) and cam (17). The wheel (19) is retained by a part (28) which is subject to the effect of a mass (32) displacing it in the event of an impact releasing the wheel (19). The rotation of this wheel is slowed by a blocking mechanism (39, 40) which it drives via a driving gearwheel (37) with which it is in engagement. When this driving gearwheel (37) jumps out of the toothing (36) extending only over 240 DEG , the wheel (19) is released and executes a sudden rotation, thereby releasing the plate (15) which itself releases the striking pin (9) which is then activated in order to unhook the belt (2).

Inventor: FOERSTER HANS-JOACHIM
IPC: H03L1/02
Filed: 1984-07-12
Abstract: Spreads in the frequency/temperature characteristic of crystal oscillators require individual calibration of the oscillating crystals. The corresponding compensation values are stored in a memory array ready to be called up at a temperature address. The compensation values are generated using a phase locked loop having only one standard frequency as reference frequency. The frequency deviation of the oscillator at the respective existing temperature is converted into a voltage value and digitally stored. <IMAGE>

Title: Multi-cycle control of power actuating elements having a variable clock frequency
Inventor: VOLLMAR WILFRIED ING GRAD
IPC: H02M5/257
Filed: 1984-08-17
Abstract: In a method for multi-cycle control of actuating elements which are connected to an AC voltage network and in each case supply a load, and in which the power actuating elements are connected through in synchronism with the network voltage for full network cycles when the voltage (UC) on a capacitor which is charged with a control voltage reaches an upper threshold value (UH1), and are disconnected again when the voltage (UC) on the capacitor which is discharged by a load-dependent voltage reaches a lower threshold value (UH2), it is intended to ensure that the load of the AC voltage network during operation of the power actuating elements with a variable clock frequency is smoothed. For this purpose, the upper threshold value (UH1) is briefly reduced at uniform time intervals to a lower level (UH3), or the lower threshold value (UH2) is briefly raised. The time intervals of the reduction and raising, respectively, of the threshold values (UH1) and (UH2) for controlling the individual power actuating elements are offset uniformly with respect to one another.
