Title: Swimming aid with muscle-power drive which is similar to a bicycle system
Inventor: MARCHNER OTTO
IPC: A63B35/10
Filed: 1985-06-19
Abstract: The subject matter of the invention is an aid for sport and/or play which in design and purpose corresponds to a bicycle to an appropriate extent and is adapted to the posture of a swimmer in the water. The said aid is intended to enable the swimmer to use the known rhythmical circular movement of the legs used in riding a bicycle as a natural source of power to generate rotary movement of a propelling screw (ships screw) or of other fins and the like which bring about natural locomotion in the water. The crucial difference from other means of locomotion in or on the water, such as boating etc., is that locomotion is produced by the posture of a swimmer and also that the whole body of the latter, apart from the head, is situated in the water.

Title: Method of determining the load on forms of transport
Inventor: DIJK JOHANNIS VAN DIPL ING
IPC: G07B15/02
Filed: 1985-09-02
Abstract: To carry out the method, tickets on which at least the machine-readable data of the issuing station is recorded are used. To check the validity of the tickets, portable devices are used, into which at least one entry relating to the route section in which the check is carried out is entered manually. For checking, the ticket is inserted in the device, which reads the recorded issuing station and stores it, with the entered route section, in an intermediate memory. When the checking is finished, the content of each intermediate memory is transferred to a main memory. The data collected in the main memory can be evaluated using a suitable data processing system.   The method makes it possible to determine the traffic flows almost continuously, with a precision which was not possible with earlier methods, and without additional staff costs.

Patent DE-3611221-A1 (DE)
Title: Internal combustion engine having inlet and outlet valves
IPC: F01L9/20
Filed: 1986-04-04
Abstract: A circuit of an electromagnetic load having a freewheel requires (for energy saving reasons) a high switching-on current and a relatively low, pulsed holding current. In order to save an expensive transistor, whose load capacity is matched to the high switching-on current, it is proposed according to the invention to control the switching-on current by a thyristor and to control the holding current by a transistor. According to the invention, use is in this case made of the fact that a transistor can be considerably overloaded briefly, without being damaged. A further embodiment uses a PTC element in order to prevent overloading of the transistor.

Title: Process for exhaust air purification and recovery of solvents from solvent vapours contained in the exhaust air and an adsorbent-containing vessel through which the exhaust air flows
Inventor: BIELER ERHARD
IPC: B01D53/04
Filed: 1986-12-23
Abstract: In a process for exhaust air purification and recovery of solvents form solvent vapours contained in the exhaust air, the exhaust air flows through a vessel containing an adsorbent, preferably activated charcoal. At predetermined intervals, a flushing vapour flows through the adsorbent for the desorption of solvents accumulated in the adsorbent during the exhaust air purification. To avoid condensation of flushing vapour on the cold interior wall surfaces of the vessel, before the beginning of each desorption process, these are heated to a temperature which is higher than the temperature of the flushing vapour used, but is not less than 100@C. The shell of the vessel is constructed as a heat exchanger which enables heating by heat introduced externally.
