Patent DE-4034271-A1 (DE)
Inventor: ERICHSEN JOERGEN
IPC: B62L1/14
Filed: 1990-10-27
Abstract: A rim brake is disclosed, in particular a double jaw brake having one or several rubber spring elements (6) which restore the brake jaws (3) to their initial position or which prestress them in the initial position. These rubber spring elements allow a completely new braking performance, in comparison to the conventional, rigidly mounted brakes, such as the cantilever brakes, because the rubber yields to a certain extent, according to its Shore hardness, although it ensures the required stiffness. The design of a rim brake with a rubber spring element is substantially more simple and unproblematic, as no seals are required, and the user can mount such a rim brake without danger of mistakes.

Title: Arrangement of rinsing tanks for surface treatment processes - has several intermediate tanks replaced by one tank extending downwards through building
Inventor: KNOBLOCH MANFRED DIPL ING
IPC: C23G3/00
Filed: 1990-12-22
Abstract: Existing methods of computing the layout of tanks for rinsing a throughout of workpieces to attain a given small concentration do not fully exploir the possibilities for optimising variables such as floor area, production time, water consumption etc. A more efficient layout can be achieved by utilizing building height or space under the finishing plant floor. - In a typical proposed system a number of intermediate tanks is replaced by one tank (2) which is extended to occupy a pit dug in the floor under the tank installation (1, 2, 3). Alternatively, if the installation is on an upper floor, the intermediate tank can be of the same section as the other tanks but extended downwards through the floors.

Title: IC engine knocking detector for motor vehicle - measures periods for preset crankshaft angles to ensure correspondence with predetermined piston positions
Inventor: NAKAGAWA AKIHIRO
IPC: G01M15/11
Filed: 1991-09-20
Abstract: The time taken for the crankshaft to move over two preset angles is constantly measured and compared with programmed and previous value. Any misfires are immediately detected through the time shift. No pressure sensors are required. The programmed values are derived from the engine dynamics and the external conditions, e.g. air-flow, engine temp. etc. The first time period covers an angle of the compression stroke to before TDC. The second period covers the angle from the end of the first period to the start of the next first period. The control also computes the acceleration of the crankshaft in the different periods. ADVANTAGE - No separate pressure sensors required for each cylinder; simple electronic control.

Abstract: A process for producing conical bores on a work piece by means of a honing tool (1) which has a central carrying body (2) and is arranged, by means of said body, on the spindle (41) of a honing machine. Said process makes possible the production of continuously smooth cone surfaces by the honing surfaces being guided, essentially on spiral paths, in accordance with the predetermined cone inclination until the predetermined cone profile has been achieved. The average cutting speed is held at an essentially constant value by a computer-aided control of the displacement speed, of the speed of widening in the radial direction and the circumferential speed. A honing tool which is particularly suitable for carrying out the process has, distributed symmetrically on the carrying body (2), segments (5) which are mounted such that they can pivot in radial planes, carry radially outwardly pointing honing elements (20) and the pivoting movement of which can be controlled by means of a widening device (21). As drive of the widening device (21) there is provided a push rod (48), extending through the honing spindle (41), designed as hollow shafts, and drive rod (42), with a circulating-ball-screw mounting (50) in the region of the drive by an electric motor (56) and a reduction gear mechanism (52). <IMAGE>
