Patent DE-4243438-A1 (DE)
Inventor: ZAMPINI STEFANO DIPL ING
IPC: B02C19/06
Filed: 1992-12-22
Abstract: 2.1 The invention has the object of increasing the loading, with the material to be comminuted, of the gas or steam jets used for milling in a fluidised bed consisting of granular material, in order thus to obtain a better utilisation of the energy of the jets. 2.2 This is achieved in that, when the jet emerges from a nozzle, in the peripheral region of the nozzle cross-section, the size of the jet impulse changes at least twice between a minimum and a maximum value and, in the core region of the nozzle cross-section, it is equal to or smaller than the minimum values of the peripheral region.   2.3 In the regions having a low jet impulse directly after emergence of the jet from the nozzle, a negative pressure gradient forms, in this arrangement, from the environment to the core region of the jet, so that flow channels result transversely to the flow direction of the jet, through which flow channels the particles of ground material are sucked in as far as the centre of the jet and are accelerated here, in the further course of the jet, to the impact speed necessary for their comminution. <IMAGE>

Title: Transverse pull for rim brakes for bicycles
Inventor: LEITER BERNDT
IPC: B62L1/14
Filed: 1993-02-12
Abstract: The invention relates to a transverse pull for a rim brake for bicycles of the cantilever brake type. A transverse pull of this kind is fitted in inset eyelets of pivoted levers and to some extent forms an equilateral triangle which is formed by a holder which is connected to the brake lever by a Bowden cable. By virtue of their different lengths in the assembled condition, transverse pulls form triangles of different sizes which take the different types of bicycle, some of which have different mudguards, lamps or fork sizes, into account. The advantage of the invention is a transverse pull with more than two nipples which are fitted into the inset eyelets in the pivoted levers, in each case depending on the length of transverse pull required for forming a sufficiently large triangle.

Title: Simultaneous braking system for bicycle wheels - has freewheel in pedal mechanism with double control cone engaged by screw-thread with alternative bodies
Inventor: STRIEGNITZ ARIBERT
IPC: B62L3/08
Filed: 1993-03-10
Abstract: The braking force for the wheels is generated by the pedal mechanism, this having a freewheel locked by back-pedalling. The freewheel has a double control-cone (16), which is brought by a flat thread (15) into engagement with one of two freewheel bodies (6,7). The braking-force distribution unit forms a single assembly with a force-limiter. A brake-load selector acting via a flexible shaft and a screwed spindle limits working movement of the distribution-unit lever, this having three arms. The control ropes for the two brakes can be mounted alongside or one behind the other on one of the levers. USE/ADVANTAGE - Simple reliable simultaneous braking system for bicycle wheels generates both propulsion and braking forces.

Title: Low loss amplitude- and phase-control of audio loudspeaker
Inventor: HEINEMANN GERHARD DIPL ING
IPC: H04R3/04
Filed: 1993-11-29
Abstract: The method provides low loss amplitude and phase directed control of a loudspeaker (5), particularly for active noise compensation in the l.f. audio range of around 20 to 500 Hz. The frequency step ratio of the loud speaker (5) is compensated by signal processing. To achieve a small device size and a good resonance behaviour, the loud speaker (5) at its membrane reverse side, is closely encapsulated with a housing (6). Power is supplied to the loud speaker almost loss free via a high clock frequency operating switch unit (3,4) according to a regulation or control circuit. To compensate the resonance characteristics of the loud speaker (5), the control signal (1) proportional to the detected interference vibrations is multiplied with the inverse resonance frequency of the loud speaker (5) and a corrected control signal (7) for the loud speaker (5) is provided.

Title: Safe-condition monitoring unit for electrical load device
Inventor: LORENZ JOSEF DR
IPC: H01H37/04
Filed: 1993-12-02
Abstract: The monitoring of electrical load devices, such as road vehicle ventilation fans or windscreen motors, a unit is used that has a number of resistors (17 - 19) formed on a ceramic substrate (3). The resistors are supplied with power and produce a heating effect. This is countered by the action of a generated air-flow in a channel (10). The substrate is heated and serves as a temp. sensor. If the temp. exceeds a set level, the sensor causes an electromechanical contact breaker assembly (20) to open.  The resistors can be formed as thick film devices.
