Patent DE-4313763-A1 (DE)
Title: Open bicycle frame
Inventor: MICKENBECKER PETER
IPC: B62K3/06
Filed: 1993-04-27
Abstract: When transporting loads or children stable bicycle frames with a low opening are important in order for it to be possible to get on/off the bicycle, even when the rear luggage carrier is well loaded, without having to swing the leg over the latter. However, ladies' and Berceau frames are unstable. (Cross)mixed frames are sufficiently stable for conveying, for example, 2 children, but are often not sufficiently far drawn down. In addition, cross-mixed frames are expensive to manufacture. Berceau frames are unstable because the upper tubes are not supported upwards/downwards at the bend. According to the invention, Berceau frames are reinforced by reinforcements (8), (10) engaging on the bends of the upper tubes in the direction of the saddle pillar or bottom-bracket bearing. In this manner, bicycles can be manufactured which despite having a low opening are approximately as stable as men's frames but hardly more expensive/heavy than Berceau frames. <IMAGE>
Patent DE-4314009-A1 (DE)
Title: Circuit
Inventor: NEUBAUER GERALD DIPL ING
IPC: H01H47/22
Filed: 1993-04-23
Abstract: The invention relates to a circuit, comprising a relay made of a coil with a core and an armature which can move when current flows through the coil, and comprising a device which enables the circuit to be supplied with a voltage which is higher than the maximum permissible DC control voltage for the relay. The invention is constituted by the fact that the device comprises a converter (9a), which converts magnetic energy into electrical energy and is exposed to the magnetic field of the coil (3), and an interrupter (7), to which electrical energy can be applied by the converter (9a) and which can be controlled by the latter, is situated in the supply circuit (6) for the coil (3), interrupts the supply current for the coil (3), after said supply current has been turned on, shortly after the magnetic flux of the coil (3) has caused the armature (2) to move, and subsequently turns it on again when the magnetic flux of the coil (3) is just preventing any movement of the armature (2) in the opposite direction. Such a circuit is distinguished by simplicity. <IMAGE>
Patent DE-4324763-A1 (DE)
Title: Electrical snap-action switch having duplicated break and make contacts, and a lock which secures its operation (ensures its operation)
Inventor: EMKEN GEORG DIPL ING
IPC: H01H13/28
Filed: 1993-07-23
Abstract: In principle, switches of this type have a quality problem with respect to a reliable switching behaviour and must be produced in a costly and labour-intensive manner. It is necessary for both moving contacts to change over simultaneously and no undefined state of contact making is allowed to exist since this would result in the switch causing incorrect operations, such as a short circuit between two circuits, for example, in operation. In order to overcome the said quality problem and to be able to produce such switches automatically, a new switching system has been designed and, in this case, a fundamentally new function for these switches has been integrated, namely the locking of the moving contacts by means of a tooth system. This results in a greatly improved product, particularly in terms of quality and production.

Title: Method of reprocessing ash formed in the course of waste (refuse) incineration, particularly domestic waste incineration, for use in road construction
Inventor: KRAS KLAUS PROF DR
IPC: C04B18/10
Filed: 1993-11-05
Abstract: This is a method of reprocessing waste incineration ash in such a way that the waste incineration ash is suitable for use in road construction and in earthworks. For this purpose, the dominant, water-soluble calcium sulphate has to be bound in such a way that threshold values prescribed for water resources compatibility can be adhered to. This is achieved by the ash being stored with exclusion of air to prevent the formation of monocarbonate, resulting in complete binding of the calcium sulphate in ettringite.

Patent DE-4344696-A1 (DE)
Title: Oil cooling channel in cylinder head of air cooled IC engine
Inventor: TRENC FERDINAND DR
IPC: F01P9/04
Filed: 1993-12-27
Abstract: The cooling channel (1) has a rectangular cross section with height c (0.1 to 0.3 times the piston stroke) and width a (0.005 to 0.04 times the piston stroke). The entrance (2) into the cooling channel is on the axis (B-B) of the projection of the outlet valve onto the piston cross section. The exit (3) from the cooling channel is on the axis (C-C) of the cooling air stream and on the side the air hits the engine head. The position of entrance and exit to each other is not diametrically opposite each other, thus dividing the cooling channel into two segments of different length L1 and L2 where L2 is greater than L1 by 20-50%. The laminar oil stream hits the inside of the cooling channel being divided into two streams of different intensity. The oil stream along the short path will cool the head and the stream along the long path and will heat the part of the head where the fuel inlet valve is, keeping the temperature distribution uniform across the head. The distance d of the entrance from the front plane of the engine head is about where the position of the first piston ring in the top dead centre is. The exit is made flush with the bottom of the cooling channel.
