Title: Brake for pedal bicycles - has freewheel with brake drive, brake force distributor on frame, and brake force limiter
Inventor: STRIEGNITZ ARIBERT
IPC: B62L5/00
Filed: 1992-05-21
Abstract: The brake has a brake drive, a brake force distributor, a brake force limiter, a brake load switch, two brakes: and two hand brake levers resp. twist grips. The brake drive may be variable, or may be associated with the crank. The brake drive is located on the bottom bracket bearing shaft, outside the crank housing, or may be integral with it, to form a freewheel. The control drive body has holder for Bowden cables. There may be a foot control. The brake force distributor is connected by the cable to the brake drive, for variable positioning of the frame. The brake force limiter is connected to the brake load switch, via a flexible shaft. The brake drive may operate mechanical cable pull brakes, or hydraulic oil pressure brakes. ADVANTAGE - More effective, large brake forces produced by foot control, for simultaneous braking of both wheels.
Patent DE-4221876-A1 (DE)
Title: Improved protection circuit for superconducting coils during quenching - uses shunting switch operated by controller reacting to current change in superconducting coil
Inventor: ISHIGAKI YUKIO
IPC: H02H3/02
Filed: 1992-07-03
Abstract: The circuit consists of a superconducting coil (2) which is powered by a supply (6) via a first switch (5) with DC bias. The circuit also contains a protection resistance (3) in parallel with the coil to dissipate the coil energy in the case of a malfunction. The circuit also contains a DC current interruptor (4) in parallel with the resistor (3) and a controller (7) which keeps the interruptor (4) normally opened but closes it when the current flowing through the coil (2) must be shunted. It also subsequently opens the switch (5) and opens the interruptor (4) again. The controller pref. operates following a signal from a DC-current detector (1). The circuit pref. also contains a DC current detector (8) which measures the current through the coil (2) under the failure condition and directs the controller (7) to open switch (5) if this current reaches or exceeds a limit value. USE/ADVANTAGE - The circuit avoids the problems occurring with multiple parallel connected interruptors due to non simultaneous operation, which is conventionally used. It avoids the use of a series resistance in the current supply circuit which under normal operation consumes energy continuously. The use of the switch (9) prevents excessive heat being dissipated in the protection resistance (3) during normal operation. The circuit is used together wherever superconducting coils are used, e.g. in accelerators, nuclear fusion reactors or energy storage devices.
Patent DE-4224958-A1 (DE)
Inventor: REICH WERNER DR ING
IPC: F01K23/06
Filed: 1992-07-24
Abstract: The invention concerns a method and device for the operation of a combined-process power station burning solid fuels, in particular lignite, the compressed hot air heated in a heat exchanger (7, 8) through which the exhaust gases from a boiler (1) pass being further heated by a separate combustion process (18) to give a hot-air/exhaust-gas mixture which is then fed to a gas turbine (28). The aim of the invention is to ensure that the power station can be operated efficiently and safely when burning solid fuels, in particular lignite. This is achieved by virtue of the fact that the hot air is further heated indirectly in a separate, series-connected, solid-fuel-fired combustion chamber (18) with facilities for liquid-ash removal and the exhaust gases from this series-connected combustion chamber are utilized, independently of or in conjunction with the exhaust air from the gas turbine, in the power-generation process or in separate processes to produce energy.

Title: Electrolysis cell for mfr. of ozone - comprises anode and cathode chambers sepd. by solid electrolyte membrane
Inventor: STUCKI SAMUEL DR PHIL
IPC: C25B9/19
Filed: 1992-08-21
Abstract: Electrolysis cell has a solid electrolyte membrane sepg. the anode and cathode chambers. The membrane is on the anodic and/or cathodic side with a planar porous electrode or an electrode of electrically conducting material and a porous coating in surface contact, esp. with outer actuation of the anode surface to mfr. ozone on overrunning the anode. The cell housing has an electrically insulated current feed to one of the electrodes and consists of two cell housing shells sealed to each other, of which one partially or completely encloses the cathode side and the other the anode side. The solid electrolyte membrane is held between front sides or sealing surfaces of the shells and sealed. The sealing pressure between the sealing surface of the shells and the surface pressure of both electrodes on the membrane is specified by outer pressure mechanisms. The novelty is that the bearing pressure of both electrodes (3,9) on the membrane (7) is adjustable, independently of the sealing pressure, by an outer device (4,5,10,13,14) for a pressure mechanism (5,8) leading through the cell housing wall (30) to the anode or cathode chamber (28,29). The end section (17) of a bolt (5,12) fed through the wall (30) is connected to a pivot (18) fitted to the back side (16) of an electrode pressure plate (8). The pivot allows centering and/or swivelling of the planar electrode (9) diagonally to the adjustable axis (22) of the bolt (5,12) in a parallel plane to the membrane (7). The bolt (5) is adjusted using the device (4,5,10,13,14). The electrode (3) is arranged on a flat section of a plate (27) or the inner wall of the cell housing (15) in a parallel plane to the membrane. USE - For mfr. of ozone.
Patent DE-4228776-A1 (DE)
Inventor: NOTAR ROBERT DIPL ING
IPC: B01F1/00
Filed: 1992-08-28
Abstract: A carbonator having a cooling system which is controlled by a controller responsive to input signals generated by an ambient temperature sensor, an ice thickness sensor and a water level sensor. After an initial ice build up following first turn-on of the system and depending on the ambient temperature sensed by the temperature sensor, the cooling system will turn on for a predetermined ON period followed by a predetermined OFF period. These ON and OFF periods are variable as a function of ambient temperature as sensed by the temperature sensor and will recycle in absence of any carbonated water removed. If, however, water removal takes place, the OFF period is interrupted and system turn-on will occur the next time a signal from the ice sensor is received and the ON and OFF cycle as determined by the system controller will resume unless it is again interrupted by another water removal signal from the water level sensor.

Patent DE-4311191-A1 (DE)
Inventor: BECKER MANFRED
IPC: E02F9/22
Filed: 1993-04-05
Abstract: A hydraulic system is described which has a variable-displacement hydraulic pump (10), the outlet pressure of which can be controlled as a function of a pressure applied to a load-indicating connection (18), a supply tank (22), a hydraulic function (12, 13, 14) with a feed line (34), and a valve arrangement (16) located between hydraulic pump (10), supply tank (22) and hydraulic function (12, 13, 14). In order to produce a load signal absent at the hydraulic function (12, 13, 14), by means of which load signal the hydraulic pump (10) can be regulated, it is proposed that a valve (24) be arranged between the feed line (34) and the load-indicating connection (18). A control spool (26) of the valve (24) is pushed by a spring (40) and a pressure acting on its first side into a closed position and by a pressure acting on its second side into an open position in which a control connection between the feed line (34) and the load-indicating connection (18) is open. Reversing valve means (42, 44) are provided, by means of which different pressures can alternatively be applied to the first and the second side of the control spool (26). When using a hydraulic function (12, 14) with a constant-flow hydraulic circuit, the first side of the control spool (26) is connected to the supply tank (22) and the second side of the control spool (26) is connected to the feed line (34) by the reversing valve means (42, 44), and, when using a hydraulic function (13, 14) with a constant-pressure hydraulic system, the first side of the control spool (26) is connected to the feed line (34) and the second side of the control spool (26) is connected to the pump outlet by the reversing valve means (42, 44). <IMAGE>
