Patent DE-3544241-A1 (DE)
Title: Method of cleaning edges on hollow ware of pasty or dried - formerly pasty - coatings
Inventor: KLUG JOCHEN
IPC: C04B41/53
Filed: 1985-12-14
Abstract: The invention comprises a method of cleaning edges on hollow ware, such as household dishes and the like, during the mechanised or automated application of pasty coatings such as enamel slip and the like to the surfaces of the hollow ware, the edges of which must be freed again of the coatings to avoid quality deficiencies and to ensure the success of subsequent operations. In contrast to previously known solutions, in which sufficiently accurate wiping results could not be achieved due to existing inaccuracies in preceding operations or due to relatively great production tolerances of the wiping devices, and extensive follow-up work was necessary, edge cleaning which is reliable and requires no follow-up work is accomplished by the method according to the invention. This essentially takes place by the hollow ware resting with the edge on the conveyor belt being subjected, in addition to the transporting movement, to a vibratory movement, which is suitable for removing the undesired coating in the edge region of the hollow ware. Since the hollow ware rests freely and no securing or arresting is necessary, the pasty coatings applied on the remaining surfaces of the hollow ware are not affected or damaged and the previously achieved quality of the products is fully retained.

Patent DE-3601299-A1 (DE)
Title: Method for controlling the applied ignition in internal combustion engines
Inventor: JOHANSSON SVEN HANS
IPC: F02P5/15
Filed: 1986-01-17
Abstract: For each engine speed the ignition voltage is generated at a firing point, which at low engine loads corresponds to a larger spark gap, whereas at higher engine loads the ignition voltage is generated at a retarded firing point, which corresponds to a smaller spark gap. At the same time, the firing point is controlled, essentially over the entire engine load range, so that the ignition voltage, varying in a known manner as a function of the engine load and the spark gap, fluctuates within comparatively narrow limits.

Patent DE-3619209-A1 (DE)
Title: Device for visually detecting foreign bodies
Inventor: DOMANN HELMUT
IPC: F21V15/00
Filed: 1986-06-07
Abstract: In the internal space (11) of a headlight system, an optical transmitter (12) and at least one receiver (14) are arranged. When the lens (10) is clean, the radiation emitted by the transmitter (11) passes the lens (10) almost undeflected. Only a small proportion is reflected at the glass/air boundary face and impinges on the receiver (14). The operability of the transmitter (12) and of the receiver (14) can be continuously checked with the aid of this small proportion. If there are dirt particles (17) located on the outside of the lens (10), a proportion of the radiation dependent on the degree of soiling is reflected and the proportion impinging on the receiver (14) increases. A cleaning system can be triggered. The device is of simple construction and is largely free of interfering influences. <IMAGE>

Title: Automatic plate release with automatic return mechanism, plate-opening mechanism with automatic raising mechanism
Inventor: ANAGNOSTU KONSTANTIN
IPC: A61N5/00
Filed: 1987-05-12
Abstract: The patent claim relates to an invention which has the object of simplifying the exchange of the lamps and/or cleaning and/or repair and maintenance. Aluminium profiles and/or plastic profiles have preferably been used for this. They form two frames lying one above the other (supporting frame and holding frame), the supporting frame receiving the entire electrotechnics as well as reflectors and fan and the holding frame enclosing the acrylic glass cover. The two frames are connected to the respective rear longitudinal part by means of hinges. In the front longitudinal parts, electromechanical or simply mechanical locks are integrated in the supporting frame, and the catches fitting the latter are integrated in the holding frame. A pneumatic spring is mounted in each case on the left-hand side and right-hand side on the side pieces (head pieces). The holding frame is moved downwards counter to the force of the pneumatic springs and snapped into the locks. When the locks are released the holding frame automatically rises. The required work can then be carried out quickly and without difficulty. This is very important for the commercial use of sunbeds since these have to be cleaned several times a week and lamps have often also to be changed.
