In consequence, the contact blades can be mounted in multilayer printed-circuit boards without any use of force.
Patent DE-3120084-A1 (DE)
Title: Method for the digital transmission of information, in which the coding is effected by the halfwaves or periods of alternating currents
Inventor: DIRR JOSEF ING GRAD
IPC: H04L27/24
Filed: 1981-05-20
Abstract: The methods for the digital transmission of information items for data, voice or image transmission via cable or radio require elaborate terminals and also considerable bandwidths, particularly due to the transmission code. Although optical waveguides provide more bandwidths, they are expensive and cannot be used for radio. The invention uses a binary code as the transmission code. As code elements, the halfwave or the period of an alternating current with the characteristic states of large amplitude value (large CE in the figure) and small amplitude value (small CE in the figure) are provided which are sent in a direct sequence of positive and negative halfwaves or periods (codeword 9 bit in the figure). The small amplitude value only has half the magnitude of the large one. Apart from a direct transmission via a communications path, a frequency-(figure) or time-division multiplex transmission can also take place. The invention can be used both in baseband and in modem technology and can be used in existing carrier-frequency systems and in PCM systems, in microwave links, radio broadcasting and television. <IMAGE>

Title: Air-conditioning system for a motor vehicle, in particular for a passenger car
Inventor: FEHR WERNER ING GRAD
IPC: B60H1/00
Filed: 1982-08-11
Abstract: Air-conditioning systems for motor vehicles, in particular for passenger cars, are composed essentially of a housing in which a heating element, an evaporating element, a blower and means for influencing the air stream which acts on the heating element are arranged. In known systems, the arrangement of evaporating element and heating element is such that initially the entire quantity of air flows through the evaporating element and then depending on the heating requirement a corresponding part of the cooled quantity of air is directed through the heating element and thus warmed up. The known systems have several disadvantages, in particular with respect to the constructional volume and the energy requirement. In order to avoid these disadvantages, it is therefore proposed to arrange the heating element and the evaporating element in parallel with respect to the air flow and to provide means for influencing the partial air flows carried respectively through the heating element and the evaporating element. At the same time, the means for influencing the respective air flows are to be connected to one another in such a way that a change in the air flow rate through the heating element results in an opposing change in the air flow rate through the evaporating element.
