Title: Device for closing the circuit of brake lights for motor vehicles
Inventor: SCHLENKE HUBERT ING GRAD
IPC: B60Q1/44
Filed: 1981-03-13
Abstract: The invention relates to a device for closing the circuit of brake lights for motor vehicles. The essential feature of the invention is that the inertia of an inert mass at the moment of deceleration is to be used as a switching element, the intention being to exclude external influences acting on the vehicle, such as different degrees of slope of the road, vibration, different load state and the like. The invention achieves this object by means of a special movement dynamics switch whose switching elements are mounted in such a way that the previously mentioned external influences only slightly change, or do not change at all, the response characteristic of the switch. <IMAGE>

Title: Electrochemical corrosion-protection fitting for closed hot-water heating systems
Inventor: HAGEDORN WOLFGANG
IPC: C23F13/02
Filed: 1981-05-18
Abstract: Low-temperature heating systems, in particular with plastic pipes, have, as a result of the lower water temperature and by permeation of air oxygen, a high water oxygen content which is responsible for a greater corrosion risk as a result of a smaller steel surface. Detached corrosion particles are deposited, due to a lack of suitable settling places, in operation-threatening places and can by sedimentation be the cause of a reduction of the heat transmission. According to the invention, these problems are solved by the electrochemical reduction of the heating water oxygen content by means of a non-consumable electrode (2) which is acted upon with low voltage by a direct current source (3), while the negative pole is applied at the fitting outlet (5). Corrosion particles are deposited favourably in terms of settling in the lower fitting part as the vertically offset arrangement of inlet (4) in association with the guide plate (10) and the fitting wall guarantee precipitation. The use of the invention takes place in closed hot-water heating of any system, in particular in low-temperature heating systems with relatively small steel surfaces in contact with the heating water. <IMAGE>

Title: Process for drying humid gases, in particular air
Inventor: KNOBLAUCH KARL DR ING DR
IPC: B01J20/34
Filed: 1981-07-29
Abstract: In a process for drying humid gases, in particular air, with an adsorbent and regeneration of the adsorbent charged with moisture, humid gas is passed over a carbon-containing adsorbent packing impregnated with a hygroscopic salt. By applying an alternating voltage to the laden electrically conducting adsorbent packing, this is heated and the moisture is removed, whereupon the dried adsorbent is again charged with humid gas in the circulation. As a result, repeated use of the adsorbent is possible. A preferred adsorbent is activated charcoal which is impregnated with a 5 to 20% strength by weight, preferably a 10% strength by weight, solution of a hygroscopic salt. Good results are obtained after impregnation with a 10% strength by weight calcium chloride solution.

Title: Arrangement for controlling the air-fuel ratio of an internal combustion engine of a motor vehicle
Inventor: OHARA YOSHIAKI
IPC: F02D41/14
Filed: 1982-01-15
Abstract: An arrangement for controlling the air-fuel ratio of a motor vehicle driven by an internal combustion engine contains an emission control system with a three-way catalytic converter for controlling the air-fuel ratio according to the operation of the engine. A vacuum sensor for detecting the heavy load operation of the engine (an engine speed detection circuit and a circuit for supplying a predetermined voltage) are provided. The engine speed detection circuit is so designed that it generates an output signal when the engine speed is lower than a predetermined value. A feedback control circuit controls the air-fuel ratio to be at the stoichiometric air-fuel ratio in the normal operating state. A first switch device is activated by the output signal of the vacuum sensor, in order to connect the output of the circuit for supplying a predetermined voltage to the input of the feedback control circuit when heavy load operation is detected, and to deactivate the feedback control circuit. A second switch is activated by the output signal of the engine speed detection circuit in order to cease control of the air-fuel ratio in order to supply the engine with a rich air-fuel mixture by way of the carburettor. <IMAGE>

Patent DE-3216683-A1 (DE)
Title: Device for automatic expansion compensation during the clamping of a workpiece
Inventor: KIRCHEN REINHARD
IPC: B25B1/18
Filed: 1982-05-04
Abstract: The invention provides a device for automatic expansion compensation during the clamping of a workpiece on a machine tool, in particular a deep-hole drilling machine, in which the workpiece held in clamping elements undergoes thermal expansion during the machining, which thermal expansion is determined via at least one of the clamping elements by the force increase developing on this clamping element and is used for re-adjustment at the clamping element, which re-adjustment permits expansion compensation to any extent without the applied force in the clamping elements consequently increasing, so that the same applied force always prevails at the workpiece. This is achieved by virtue of the fact that the workpiece can be clamped in place by means of a hydraulically operable thrust piston with counterstay, and that a pressure regulator is connected to the hydraulic circuit of the thrust piston, which pressure regulator responds to a pressure rise at the thrust piston and reduces the pressure in the hydraulic cylinder of the thrust piston to the previous working pressure.
Patent DE-3219530-A1 (DE)
Title: Membrane for accumulators
Inventor: VOLZ PETER DR ING
IPC: F15B1/10
Filed: 1982-05-25
Abstract: Taking as a basis membranes for accumulators, in particular for hydropneumatic accumulators having a housing divided by the membrane into a space of variable volume which can be filled with pressure medium and such a space which can be filled with gas, in which means for reducing permeation are provided but which have the disadvantage that the adhesion between a barrier layer and a laminarly constructed membrane body is deficient and the deformability of the membrane is adversely affected, the present invention proposes arranging in certain regions in the neutral zone of the membrane a barrier layer of a material having a high permeation coefficient. Integral or interlocking connections are established between the barrier layer and the membrane layers. If normal operating stresses are assumed, the membrane layers are also durably held together by a combination of interlocking and integral connections. <IMAGE>

Patent DE-3225867-A1 (DE)
Title: Internal combustion engine with an exhaust turbocharger
Inventor: WEBER RAINER JOERG
IPC: F02M26/36
Filed: 1982-07-10
Abstract: In an internal combustion engine with an exhaust turbocharger, a bypass line is provided between the intake pipe connected to the charger and situated downstream of the throttle valve and the exhaust pipe opening into the turbine. Arranged in the bypass line is a valve which shuts off the bypass line only when the exhaust gas pressure in the exhaust pipe exceeds the charging pressure in the intake pipe by a certain amount and a connection is having a disadvantageous effect on the performance of the internal combustion engine. Below this pressure range, the valve is open and the connection between the intake pipe and the exhaust pipe is free. In the operating condition of the internal combustion engine in which the charging pressure is higher than the exhaust gas pressure, it is thereby possible for fresh gas from the intake pipe to pass into the exhaust pipe and for automatic supplying of secondary air to take place. If, on the other hand, the exhaust gas pressure is higher than the charging pressure, exhaust gas flows across from the exhaust pipe into the intake pipe, automatic exhaust gas recirculation thus taking place.
