Title: Bicycle with a small front wheel over which a platform-like carrier is mounted, which carrier has foldable walls which result in various, expedient, structural shapes by folding up
Inventor: SASU IOAN DR ING
IPC: B62J7/06
Filed: 1989-03-31

The novel bicycle makes possible an increased capacity for transporting goods and children with conditions which are optimal for stability and loading weight. The bicycle has a front wheel with a small diameter over which a carrier with foldable walls is mounted. Folding up the basket walls in different ways results in various, structural shapes, each depending on the cyclist's requirements. Transportation on the bicycle.
Patent DE-3912483-A1 (DE)
Title: Baking appliance door lock - with three possible door lock positions
IPC: E05C3/04
Filed: 1989-04-15
Abstract: The door for a baking or steaming appliance has a spindle (13) with a handle (14), a pin (16) and a detent groove (17).  The latter cooperates with a detent bar (9) loaded by two springs in a slot in a closure block on the appliance frame.  In the position(S) the door is closed and locked. In position, (Z) the door is free to open but is retained by the emergency detent after it has opened a slight gap. This relieves the pressure and heat before a full opening. In position (O) the door is open. ADVANTAGE - This guarantees a pressure-tight seal for the door and protects the operator from injuries when opening the door too quickly.

Patent DE-3924204-A1 (DE)
Inventor: DAUSEND AUGUST DIPL ING
IPC: B63B1/40
Filed: 1989-07-21
Abstract: The process of the invention and the associated device are designed to generate and maintain a gas/water mixture in the region of the bows of a ship under way. It has been shown that, to economize energy when a ship is under way, it is less important to reduce the resistance due to friction between the ship's hull and the water than to decrease the work done by the hull in displacing the water. In order to reduce the water-displacement work which has to be done by the ship, the invention reduces the displacement resistance by virtue of the fact that a gas/water mixture is generated in the form of a foam in a specified zone in front of the ship's bows. The installation used for this has metal plates or tubes (3, 4, 5, 6) extending out horizontally from the bow. Through openings in these, gas, in particular air, is blown into the water under pressure to form foam.

Title: Appts. for sensing adjustment of variable impedance device
Inventor: MOSELEY ROBIN C
IPC: H01C10/50
Filed: 1990-07-31
Abstract: The variable impedance device has an integral switch. As the variable impedance device is adjusted, a wiper alternately operates the switch between open and closed states. This is detected to indicate when the device is being adjusted. The device comprises an elongated resistive element and an elongated switching element mounted co-extensively and parallel to each other. A conductive sliding wiper is operable to electrically connect both elements at any point along their respective lengths to corresp. elongated conductive elements. The switching-element comprises a series of conductive areas that are electrically connected together and separated by an alternating series of non-conductive areas.  A variable impedance device with an end-of-travel return mechanism includes a movable actuator rigidly attached to the wiper and constrained to move between two endpoints. A spring engages the actuator near each end point such that when there are no other forces acting on the actuator the spring pushes the actuator back a predetermined distance from each end point. As the actuator traverses this distance, the integral switch pref. undergoes at least one state change.

Inventor: BERNHARDT WOLFGANG
IPC: B60T8/48
Filed: 1991-06-29
Abstract: The convenience of the brake system (1) is to be improved. The brake system (1) has a valve arrangement (19) for braking pressure modulation in the pressure accumulation, maintenance and release phases in a wheel brake (e.g. 8). The valve arrangement (19) has a restrictor (22) operative in the pressure accumulation phase. The restrictor (22) is circumvented by a by-pass line (27) in which there is a stop valve (28), which assumes its stop position (28b) in the pressure accumulation phases in anti-lock and/or drive slip control mode. Owing to the operation of the restrictor (22) in the pressure accumulation phase, the rate of pressure increase and hence the development of noise in the brake region are reduced. The brake system (1) is especially applicable to motor vehicles.
