Patent DE-3445308-A1 (DE)
Title: Bicycle frame
Inventor: REICHMANN HELMUT PROF DR
IPC: B62K19/06
Filed: 1984-12-12
Abstract: The invention relates to the frame of bicycles having an encased drive mechanism. Due to the fact that the rear lower forked tubes are arranged essentially above the encased drive mechanism (e.g. over the chain), the frame and encased drive mechanism form separate assemblies which do not engage in each other. By this means fitting and removing the encased drive mechanism is possible without the latter or parts of the frame having to be opened. The novel arrangement of the tubes permits various frame configurations which more or less resemble those of bicycles customary today.

Title: Press control
Inventor: WAECHTER FRITZ DIPL ING
IPC: B21D3/10
Filed: 1985-09-17
Abstract: In hydraulic straightening presses, a straightening position is to be approached in high-speed operation, from which the adjustable and repeatable straightening stroke is to begin in each case. In known controls, the approach of this straightening position was extremely difficult and time-consuming. In order to avoid these difficult and time-consuming manipulations, it is proposed according to the invention for the straightening position to be fixed by a stop connected to the ram being reached, said stop then acting on a control piston whose control housing can be fixed via a valve lever which can be mounted in an ergonomically favourable position in the press foundation. <IMAGE>

Patent DE-3610148-A1 (DE)
Title: Heating device for heating tricklable material
Inventor: ISENHARDT FRIEDEL
IPC: C10B1/04
Filed: 1986-03-26
Abstract: The heating of tricklable material, in particular the heating of petrol coke to produce electrodes for the aluminium industry, requires special measures if the material is not to come into contact with the corresponding heat transfer medium. For example, the heating of petrol coke for producing electrodes for the aluminium industry takes place in mixing screws through which a heat transfer oil flows. In respect of the throughput quantity and the space requirement, these mixing screws are inflexible and furthermore require special sealing devices for supplying and removing the heat transfer oil. According to the invention, however, these disadvantages are eliminated due to the fact that the heating device (1) consists of a plurality of parallel tubes (3) which are arranged vertically in a housing (2) with a slight spacing from one another, are flowed around by a heat transfer medium (6), whose cross-section widens conically from the top to the bottom, and which are connected at their upper end to a delivery device (13), in particular a distributing screw, and at their lower end to a discharge device (16), in particular star wheels, for the heated material (12'). <IMAGE>
Patent DE-3611600-A1 (DE)
Title: Method for the analog or digital coding of information for use in angle- and pulse-modulation methods
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/00
Filed: 1986-04-07
Abstract: The important factor in the coding and transmission of analog or digital information is to transmit this information reliably and economically, that is to say with a narrow bandwidth. For this reason, multi-valued coding and/or pulse-modulation methods have been developed to improve the utilisation of the transmission paths. The multi-valued coding methods could only be used reliably and with justifiable expenditure up to 16 QAM quadrature amplitude modulation or respectively up to 16 PSK phase modulation. In the invention, the transmission reliability is increased and the expenditure reduced by changing the phase in the alternating coding current in such a manner that an uninterrupted sequence of positive and negative halfwaves is produced and/or the transmission occurs on the basis of the angle or pulse modulation in a narrow band or only with an alternating code current of one frequency, the characteristic states being defined by the amplitude and/or phase step.

Title: Vehicle antenna for the decimetric waveband
Inventor: HOLLMANN HEINRICH DIPL ING
IPC: H01Q1/32
Filed: 1986-06-24
Abstract: Using a vehicle antenna for the decimetric waveband, especially for 900 MHz mobile radio, secondary emission from the vehicle bodywork (1) is desired by means of a compact exciter which is fitted between the vehicle bodywork (1) and the vehicle number plate (2). The exciter is constructed as a folded dipole (3) which is bent through 90 DEG  and is arranged along the two right-angled sides of an antenna housing which represents a right-angled triangle in the projection of its vertical boundary surfaces (6, 7), which antenna housing, for its part, replaces an upper corner, which is mulled away at 45 DEG , of a metallic number plate support which is fitted vertically behind the vehicle number plate (2) and has the same thickness (17), and supplements said number plate support to form a rectangle having the approximate dimensions (15, 16) of the vehicle number plate. In order to implement a diversity mode using only one antenna, the polarisation of the radiation emitted by the folded dipole (3) is changed by means of three electronically controllable switching diodes (A, B, C) which are in each case arranged between the centre and the two ends of the folded dipole (3) and the rear vertical boundary surface (7) of the antenna housing, in such a manner that it is possible to select circular polarisation, linear polarisation or linear polarisation at right angles thereto, in the main direction of radiation. <IMAGE>
