Patent DE-2834695-A1 (DE)
Inventor: LUBITZ KARL DR
IPC: G01R31/16
Filed: 1978-08-08
Abstract: A method and apparatus for inspection of ceramic parts for defects utilizes the application of an electrical test voltage to the part to be inspected, and at the same time subjecting the part to acoustic emission analysis. Use of the acoustic emission analysis allows discovery of not only defects which may arise because of the application of the electric current, but also defects or structural damage which are already existant in the part to be tested. An apparatus for carrying out the method on a high-volume basis allows rapid insertion and removal of a part between electrodes and clamps the part in place during testing.

Title: Switching system for vehicle lights - reacts to ambient light using photoelectric sensor and can also be used for lights in roadside marker posts
Inventor: ROTT JOACHIM ING GRAD
IPC: F21V23/00
Filed: 1979-01-13
Abstract: The switching system has a photodetector responding to ambient light levels and, after a given delay, alters the light level produced by the headlights of the vehicle. The same principle can be employed for lights along the roadside. The photodetector with its control circuitry and the light are located in a post (2) delineating the road and supplied from a battery, which may be charged by a solar generator (20). Lighting posts that mark roadsides in this manner ensure that the posts are clearly visible to an approaching vehicle - the light they emit is reduced when the vehicle headlights illuminate the posts.

Patent DE-2922581-A1 (DE)
Inventor: BAUMANN MANFRED
IPC: A47K10/36
Filed: 1979-06-02
Abstract: The device contains a roll of a paper web whose free end is wound around a cutting cylinder (1) in such a way that the latter is turned by the roll as a result of friction when the paper web is drawn off. In this process, a thread (2) attached to the measuring cylinder (1) winds onto the latter until a knot (3) comes up to an eye (5) and stops the measuring cylinder. The paper web is now pulled against the blade (8) by hand and a measured portion is thereby cut off. Behind the blade, the end (9) still connected to the roll of paper hangs down ready for gripping. The device can have a reserve roll of paper with a second measuring cylinder. <IMAGE>

Title: Monitoring concn. and temp. of reaction solns. - using small sample but with homogenisation by ultrasonic vibration
Inventor: FAUST UWE PROF DR
IPC: B01J19/10
Filed: 1979-06-15
Abstract: The concn. and temp.of reaction solns. involves measuring part of the soln. which is representative of the whole. The soln. is homogenised by means of ultrasonic vibration to produce turbulence. The vibration causes a temp. change in the soln. The concn. is monitored by measuring the absorption of light in a particular wavelength. The change of the extinction point with unit of time is used to monitor the reaction rate of a chemical reaction. The temp. can be monitored by the infra-red radiation it emits. Used for monitoring the progress of reactions esp. catalytic reactions and allows the measurement carried out on a small portion to be representative of the whole and also the vibration heats the soln.

Title: Curved optical fibre wavelength filter - selectively couples light from core to cladding to form high or low pass
Inventor: PETERMANN KLAUS DR
IPC: H04B10/2581
Filed: 1979-07-04
Abstract: A single mode optical fibre (1), with a core and cladding, is wound into a loop (3) to form an optical filter. The curvature of the fibre causes light to be coupled from the core into the cladding. The degree of coupling depends on the radius (R) and is greater the longer the wavelength. If light of two wavelengths is fed (e) into the core, the radius can be adjusted so that the longer is coupled into the cladding while the shorter remains in the core. For a low-pass filter, the output is taken by coupling the core of another fibre to the cladding. For a high-pass, the output is taken from the core and the curved postion is coated with light absorbing material having a refractive index equal to or greater than the cladding.

Title: Control for automatic transmission - uses torque-time curve with sections of different slope, to avoid jerking
Inventor: GROB FERDINAND DIPL ING
IPC: F16H59/38
Filed: 1979-09-21
Abstract: The control defines a torque curve for the gear's output, the curve having two or more sections of different slope. Control starts at a time defined by the point in time when the coupling laminae are applied when the gear is engaged. When the gear is disengaged, control starts at a time defined by the turbine's speed differing from the gear's output speed multiplied by the gear ratio before the beginning of the gear change. Each section of the curve has the rate of change of gear output torque constant so that a linear relationship exists between torque and time. The measured values for the throttle position and gearing output torque can be transmitted to a digital micro-computer via an a-d converter and multiplexer.

Title: Rotary-to-linear drive converter - comprises toothed belt lifted free of sliding rack by toothed driving wheel
Inventor: KUESPERT MAX
IPC: F16H19/00
Filed: 1980-02-16
Abstract: The drive mechanism converts rotary movement into linear movement without lost motion, using a toothed wheel meshing with a toothed belt. It is particularly for rapid and reproducible positioning of tools, work etc. The mechanism comprises a rack (4) extending in the direction of linear movement, and with which the toothed belt engages permanently (2) each side of the toothed driving wheel (3). The latter lifts it out of engagement with the rack, while a guiding pressure is applied to the back of the belt, at least where it passes round the wheel. This ensures that the portion of the belt out of engagement with the rack is always of constant length (A+2C).
Patent DE-3029919-A1 (DE)
Inventor: LOHNER GERD
IPC: A21C13/00
Filed: 1980-08-07
Abstract: The invention is referring to a storage carrier to be used in a fermentation interrupter for the production of rolls or similar products with a pattern. The first stage of such rolls are dough crudes in form of dough cuts whose ends are rolled or wrapped up towards the center, where they are forming a contact seam. It is necessary that during the later baking process this contact seam is ripping up or cracking and there is resulting the so called pattern (Ausbund). The possibility to produce such rolls from the dough crudes is depending on different effects during the procedure in the fermentation interrupters. For ensuring on the one side a sufficient raising effect and to prevent on the other side the access of too much air humidity, it is proposed to provide a storage carrier with a supporting framework having deepenings for taking up the dough crudes as well as a textile cover and a foam plastic layer between the supporting framework and the textile cover. Preferably the foam plastic layer and the textile cover are formed of one piece.
