Abstract: A heating and/or air-conditioning system for motor vehicles provide for a temperature stratification between two different partial spaces of the vehicle interior. The system provides for independent reduction of the air stream which can be lowered in its temperature, by control device controlling the temperature of the air stream introduced into a partial space and of a throttle device which may function independently therefrom in a channel through which the air flows to the partial space. The throttle device is arranged downstream of the control device.

Abstract: A device for regulating the heat output or heat capacity of a heat exchanger in an automotive vehicle with an actuating member to control the flow of a heat exchange medium and with a control device operating the actuating member. To provide input to the control device, signals are received from a highly rated internal temperature sensor and a lower rated heating air temperature sensor disposed at the outlet of the heat exchanger as well as a manually adjustable set point generator. The control device includes a pulse generator producing a triangular voltage of a constant frequency, with a differential amplifier for the signals of the temperature sensors as well as the set point generator. A comparator is provided for producing rectangular pulses in correspondence with the triangular voltage frequency, with a pulse width corresponding to the temperature signal of the differential amplifier. The heat exchanger is tubular and has a large ratio of heat exchange medium volume to heat dissipating surface area.

Abstract: An internal combustion engine with several cylinders, with one or several superchargers, and with an additional compressor-drive by means of compressed gas, in which during partial load of the internal combustion engine, some cylinders operate as engine while the other cylinders which operate in the meantime as compressors, supply compressed gas for the additional compressor-drive of each supercharging aggregate that supplies the cylinder operating as combustion engine with charging air.

Abstract: To avoid the lifting off and re-impacting of the flyweights (13) of a fuel injection timing device on their associated slide surfaces (14, 15) during the occurrence of a negative torque, it is proposed to transmit a part of this torque by an oil film. For this purpose, lubricating oil from the internal combustion engine flows through the timing device. At least one of the flyweights (13) cooperates as a transmission element (21) with a slide member (22) and with the two coupling parts (11, 12) whereby slide surfaces (23-28) with areal abutments are provided between the parts, between which an effective oil film can form.

Abstract: An equipment for recognizing misfiring, which is particularly suitable for permanent installation in a motor vehicle. By means of high-pass filters coupled to the plug leads between the spark distributor and the spark plugs, the change to the voltage at the spark plugs associated with the initiation of the ignition spark is sensed. The high-pass filters are so arranged that they only send on a needle-shaped output pulse signal to an analysis circuit if it appears with the change in voltage associated with the spark front. The analysis circuit generates appropriate output signals with reference pulses generated in time with the ignition pulses. The high-pass filters are preferably arranged as simple RC filters whose capacities are coupled to the plug leads by means of peripheral electrodes, which at least partially surround the insulation coatings of the plug leads.

Abstract: An adjusting device for the point of articulation or the point of deflection of a safety belt in automotive vehicles permits continuous adjustment of the angle of articulation for the safety belt in contact with the shoulder of the vehicle occupant to a predetermined value with the aid of an electric pickup for the angle of articulation, arranged at the point of articulation or deflection, and a comparison circuit connected after this pickup, which comparison circuit contains the predetermined value.

Abstract: A wound double-walled container and method of manufacturing the same from coated paper includes two blanks which are placed one above the other and which form the container walls. The blanks are arranged mutually offset in such a manner that narrow foldable strips project laterally and foladble rim portions extend at the top and bottom, which are folded over for sealing the inwardly and outwardly and endwise disposed cut edges. The folding-over takes place either after the winding of the blanks or while the individual blanks are still flat, which thereafter are wound separately one after the other about a winding mandrel and are sealed.

Abstract: A rotor with vanes is secured on the distributor shaft of the ignition distributor, by means of which ozone produced by arc formation during the interruption of the high-voltage current, is discharged through openings of the distributor housing into the atmosphere.

Abstract: An active Wien-Robinson suppression filter connected as electrical filter in the electric transmission line from a drive-pedal potentiometer of a motor vehicle to the adjusting member of the throttle valve of the internal combustion engine; the jerking of the motor vehicle which otherwise occurs frequently, can be avoided with the use of such a filter.

Abstract: A bearing support of a differential gear in an undivided axis housing with two substantially coaxial roller bearings arranged at approximately the same distance to and on different sides of the plane of the axes of rotation of differential bevel gears; each of the roller bearings supports a bearing neck of the differential gear housing within a bearing opening of the axle housing, whereby at least one of the roller bearings includes an outer race which is inserted directly into its bearing opening and is enlarged in its outer diameter, with respect to the corresponding standard diameter.

Abstract: A distribution installation for piece goods moved on a conveyor track which are distributed from a common feed conveyor to several stations of a distribution conveyor; each piece good is provided for that purpose with a coding containing an information which is detected or scanned within the area of an objective field of a scanning station arranged upstream of the distribution conveyor by a video camera connected to an electrical evaluation circuit in order to determine an exit information; to speed up and simplify the distribution, the video camera is arranged vertically above the detection station and each piece good is moved through the objective field non-oriented in the transverse direction and angularly independent about the vertical axis with a coding disposed at the top thereof which consists of a single bar group or the like whose precise detection for position and content is made possible by positioning bars and is thus reduced to a short period of time; the detection efficiency is thus unequivocal

Abstract: A windshield for motor vehicles equipped with a windshield wiper system, which, for the improvement of the wiped field, includes in its lower area strip-shaped profile members whose side facing the bottom edge of the windshield form together with the windshield surface a water-collecting channel open in the downward direction. In order to prevent the rising of water from non-wiped areas in the lower part of the windshield onto wiped higher areas, provision is made according to the invention that the upper edge area of each profile member extends along the lower edge area of the associated wiper field.

Abstract: A water conduit for water accumulating in lateral areas of the windshield of a motor vehicle. The conduit includes a main water channel formed by a molding extending at a spacing in front of the windshield and by another residual water channel located farther towards an outside. The main water channel leads without substantial deflection in a transverse direction of the vehicle to a trough or interruption, with the channel extending in the roof approximately in parallel to a longitudinal axis of symmetry of the vehicle. The residual water channel lies within an envelope line of a contour of the motor vehicle and is continued above lateral door cutouts of the motor vehicle to a rear portion of the motor vehicle.

Abstract: In a diesel internal combustion engine (10) having a low compression ratio, at least one cylinder (11) operating as engine cylinder is supercharged during starting and in the partial load operation by several cylinders (12, 13) operating as compressor. The piston of the first compressor (12) which is used for the direct charging of the engine cylinder (11), leads the piston of the engine cylinder (11) exactly so far that the air compressed by the same is fed directly into the engine cylinder (11) during the beginning of the compression stroke. At least one further compressor cylinder (13) supplies its air to an air storage device (22) which is connected with the engine cylinder (11) by way of a line (24) adapted to be closed off by a valve (23).

Abstract: An installation for assembling two parts adapted to be telescoped one into the other, of which at least one part has a radially directed projection which, during assembly of the parts, engages into a correspondingly constructed recess of the other part, whereby the first part is nondisplaceably arranged and the second part is aligned with the first part, and finally the second part during rotation threof about its longitudinal axis and simultaneous axial displacement is assembled with the first part; the second part is thereby positioned by a retaining mechanism which positions the second part with respect to the first part in relation to the joining axis while a threaded spindle adapted to be driven by a motor and held by a rigid support cooperates with the second part by way of a spring-loaded compression mechanism; the threaded spindle is thereby equipped with a slippage clutch.
