Patent DE-19540673-A1 (DE)
Inventor: LEMIRE BERTRAND
IPC: F01N11/00
Filed: 1995-10-31
Abstract: An exhaust fume probe (8) has a measurement electrode (3) with which the resistance of a metal oxide layer (4) may be measured. The metal oxide layer (4) has a reduced catalytic activity. For a predetermined air ratio, the resistance of the metal oxide layer (4) is dependent on the oxygen partial pressure in the exhaust fumes. The conversion rate of a catalytic converter (7) influences the oxygen partial pressure in the exhaust fumes downstream of the catalytic converter, and so the resistance of the metal oxide layer (4) depends on the conversion capacity of the catalytic converter. This exhaust fume probe with a simple design thus allows the operation of the catalytic converter to be tested by a simple resistance measurement.

Title: Brake drum piston adjustment for lining changes
Inventor: KEFERSTEIN HANS-GEORG
IPC: F16D65/14
Filed: 1996-02-07
Abstract: The axial orifice (21) on the lining side of the piston (2) has an inside thread (22) and is closed off by a stopper (23) remaining within the limits of the piston on the lining side. The thread-way of a return screw has a head end which projects beyond the piston when this is fully screwed in, thus indicating screw presence in lining changes. The stopper has its own ventilation hole (24). Brake piston adjustment is conventional though the nut (5) bears continuously on the friction cone (10,11). After braking, the elastic seal (20) draws the piston off the lining so that the piston has only to be drawn further out so as to lift the nut off the cone and twist it via spring (12) until the nut re-seats onto the cone, thus signifying that the piston has been adjusted to allow for lining wear etc. Re-lining calls for stopper removal to allow the return screw to be inserted in its place etc.

Title: Carbon dioxide control apparatus for aquarium
Inventor: BASTIAN ARNO
IPC: A01K63/04
Filed: 1996-06-18
Abstract: The apparatus includes a carbon dioxide bottle (6) which supplies the water of an aquarium with controlled doses of carbon dioxide. The controller regulates the release valves to provide a controlled gas injection via a bubble monitor (2) and an injector (3). When the supply bottle is empty the controller automatically switches to a smaller capacity reserve bottle (7). A warning unit (31) operates to show that the system is on reserve. When the main bottle is replaced the system automatically switches back to main feed. The dosing of the carbon dioxide is controlled by the gas pressure and by a timer (4) and a pH monitor. The pH-value is kept to a set value which promotes plant growth and which is suitable for the particular marine life in the aquarium.

Abstract: The invention concerns an electronic data processing circuit having an operating module (1, 101), such as for example a microprocessor, with at least one data memory (2, 3, 4, 5, 102, 103, 104, 105) and with a data bus (106) extending between a data memory (2, 3, 4, 5, 102, 103, 104, 105) and the operating module (1, 101). With electronic data processing circuits of the type in question the memory frequently contains information to which access should be limited as far as possible. Therefore it is necessary to take security measures to guard against manipulation of the electronic data processing circuit. Consequently the object of the invention is to produce an electronic data processing circuit of the type in question which affords better protection against undesired alterations. According to the invention, this object is achieved by an electronic data processing circuit of the type in question in which at least one coding module (20, 21, 22, 35, 107) is provided in the region between the data memory (2, 3, 4, 5, 102, 103, 104, 105) and the data bus and/or in the region between the operating module (1, 101) and the data bus. The coding module (20, 21, 22, 35, 107) is designed such that data traffic between the operating module (1, 101) and the data bus or between the data memory (2, 3, 4, 5, 102, 103, 104, 105) and the data bus (106) can be coded and/or decoded.

IPC: B29C67/02
Filed: 1997-02-26
Abstract: In a process for manufacturing thick-walled, plate-like components from plastic granules the total thickness is built-up by combining several thinner layers. Each layer is produced by feeding granules (3) onto two or more perforated conveyer belts (2), the combined depth of each layer being more than the final plate thickness, and passing each belt through its own melting station(1) where hot air flows through and melts the surfaces of the granules. After melting, the hot granulate layers (3) are placed on top of each other and passed through a forming station (6). In a process variation the heated layers of granules are fed onto a conveyer belt where they are mixed together before entering the forming station. Process equipment comprises a granulate storage container and two or more  melting stations (1) through each of which a perforated conveyer belt (2) passes and conveys granules through a hot air channel. Each perforated conveyer (2) runs parallel to a single conveyer belt (7) extending to or through the forming station (6) and ends above this belt (7) prior to the forming station.
