Title: Method and circuit arrangement for the synchronisation of the data transmission between a transmitter and a receiver with the aid of a memory
Inventor: SCHIEMANN BJOERN
IPC: G06F13/40
Filed: 1993-07-12
Abstract: The invention presents a method and a circuit arrangement for the synchronisation of the data exchange between transmitters and receivers which operate with different speeds. For this purpose, the data arriving from the transmitter are essentially passed on to the receiver via a memory. Writing to this memory takes place under defined conditions:   - The transmitter emits a write request and the receiver does not emit a read request. - The receiver emits a read request and reads the data after expiry of a time delay, which makes it possible to write to the memory in a stable manner.   Areas of use for the invention are in computing systems with a plurality of processors (telecommunications, DP) and in the signal processing of measured value pick-ups. <IMAGE>
Patent DE-4326066-A1 (DE)
Title: Control for an electric car radiator fan
Inventor: LIN CHE-TZU
IPC: B60H1/00
Filed: 1993-08-03
Abstract: A control for an electric radiator fan of a vehicle contains a high-pass filter, an inverted comparator and a relay. The inverted comparator compares the signal received from the high-pass filter with a d.c. reference voltage signal which is generated according to a predetermined critical speed and, according to the results of the comparison, it outputs an output signal which is at a high or low potential. The relay is controlled in such a way that on the one hand it switches on the electric radiator fan of the vehicle if both the output signal of the inverted comparator and the output signal of the compressor of the vehicle are at a high potential, and that on the other hand it switches off the electric radiator fan if both the output signal of the inverted comparator and the output signal of the compressor of the vehicle are at a low potential or if one signal is at a high potential and the other signal is at a low potential. <IMAGE>

Title: Method and apparatus for sorting material particles of sheet-like, fibrous or granular consistency
Inventor: AROLD JUERGEN
IPC: B07B4/02
Filed: 1993-08-26
Abstract: In a method and an apparatus for sorting material particles of sheet-like, fibrous or granular consistency, the material to be sorted, having been comminuted into equal-size particles if necessary, is conveyed with the aid of an air flow generated by a suction fan (70) through a number of vertical chambers (2, 3, 4, 5, 6) connected one behind the other, which chambers are divided by vertical partition walls (23, 24, 25, 26) into an inlet channel and an outlet channel in each case, the outlet end, located at the top, of an outlet channel of one chamber being connected to the inlet end, likewise located at the top, of the inlet channel of the following chamber. The effective cross-section of the outlet channels of the chambers following one another in the flow direction is continuously increased, so that, starting from the first chamber into which the comminuted particles are conveyed, the flow rate in the outlet channels of the individual chambers becomes smaller and smaller, and the material collecting at the bottom of the individual chambers is removed separately from the individual chambers. <IMAGE>

IPC: F24C15/20
Filed: 1993-10-14
Abstract: The sec. medium to be exhausted (9) usually consists of air mixed with steam, fumes or dust. Nozzles (1) eject steady cone shaped prim. jets of e.g. room air which mix with sec. medium to form a combined stream (10). The pressure drop associated with the velocity field of the prim. jets creates an induction zone (8) into which the sec. medium is drawn. The combined stream (10) travels into the working range of an exhaust system (2) and is extracted. The cone angle of the prim. jets is chosen between 15 and 35 deg., and the prim. stream velocity is from 3 to 25 m/s. With a distance between the nozzles and exhaust system of 500 to 2000 mm, the vol. ratio of sec. medium to prim. air is between 10 and 100. USE/ADVANTAGE - System greatly increases air and gas extraction efficiency resulting in lower investment and running costs.

Title: Infinitely variable transmission
Inventor: MIYATA HIROFUMI
IPC: F16H37/08
Filed: 1994-10-06
Abstract: In an infinitely variable transmission, in which a variable-speed belt drive and a differential are combined with one another, corresponding disc cam mechanisms are provided on the respective rear sides of movable discs of the pulleys of the variable-speed belt drive in order to move the discs in the direction of stationary discs of the pulleys towards and away from the latter. A connecting mechanism for connecting the two disc cam mechanisms is provided so that the diameters with which the belt is wound around the two pulleys can be varied in a reverse direction relative to one another, the rotational speed of the variable-speed belt drive being changed in such a way that an output gear is shifted back and forth relative to a rotating shaft between a normal rotation state, a neutral state and a reverse rotation state in order to retain a planet wheel of the differential. The output gear can be set to a neutral state by an equilibrium between the driving forces acting on the belt from the two pulleys, and the variable-speed belt drive serves as a rotating force train in the forward driving state of the vehicle, the operating frequency being higher in this state. Consequently, the frequency at which the high driving force is applied to the belt of the pulley mechanism is reduced so that the belt load is reduced, as a result of which on ...
