Title: Internal-rotor gear-type oil pump for motor vehicle internal combustion engines
Inventor: SICKINGER KURT
IPC: F16N13/20
Filed: 1982-11-22
Abstract: In an internal-rotor gear-type oil pump for motor vehicle internal combustion engines, which is flanged to the front end of the engine and in which the pinion surrounds the end of the crankshaft and is rotated by the latter, the oil is fed from the direction of the oil suction pipe via a flat oil feed conduit, the largest dimension of which is transverse to the direction of flow, essentially in a plane normal to the axis of rotation of the pump. In the entire region of transition from the conduit into the kidney-shaped suction inlet, the conduit runs along that side of the end face - the end face on the side of the kidney-shaped suction inlet - of the working chamber accommodating the gearwheels which faces away from the interior of the said working chamber. When projected onto a plane normal to the axis of rotation of the pump, the conduit runs approximately tangentially into the region between the gearwheels of the pump.

Title: Process for the direct reduction of iron ore in a shaft furnace
Inventor: BOGDANDY LUDWIG VON PROF DR IN
IPC: C21B13/02
Filed: 1982-12-03
Abstract: In the process for the direct reduction of iron ore in a shaft furnace, lumpy ores or pellets are subjected in a known manner to a flow of a gaseous reducing agent in countercurrent and are thereby reduced. A CO- and/or H2-rich gas, in most cases obtained from natural gas, is used as the reducing agent. According to the invention, a low-value reducing gas, i.e. a reducing gas having a low CO and/or H2 content and allowing a prereduction of the iron ore, is introduced into the shaft furnace in addition to this high-value reducing gas. The converter gas generated in the steel production in an oxygen-blowing converter is used for this purpose.

Title: Mirror antenna having supports, in the beam part, which generate secondary radiation
Inventor: HOMBACH VOLKER DR ING
IPC: H01Q15/14
Filed: 1983-03-03
Abstract: The invention achieves a reduction in the sidelobe level which is produced by the supports which are arranged in the beam path of mirror antennas. To this end, the reflection surfaces of these supports are at least partially provided with a surface impedance in the form of a periodic surface structure having a period length 7 = lambda /(2cos  alpha ), ( lambda  = free-space wavelength,  alpha  = support angle), whose elements are optimised in height 8 and width 9 in Fig. 3 such that the wave which is incident from the mirror is predominantly reflected in the direction of incidence. In the case of a 1.5 m parabolic antenna, a surface structure having rectangular webs has been tested, which webs were fitted on approximately 60% of the total support length. The sidelobe level in the region of the transmission angle 2 alpha  was reduced by 13 dB in comparison with an antenna having smooth supports. The same surface impedance can also be achieved using periodic structures of different shape. If necessary, the surface structure may also consist of dielectric material (Fig. 3). <IMAGE>

Title: Device for determining the parking time of motor vehicles
Inventor: BETSCH HELMUT
IPC: G07C1/30
Filed: 1983-06-11
Abstract: A device for determining the parking time of motor vehicles is proposed in which the parking time which has elapsed or the start of the parking time is represented on an electro-optical display which is controlled by an electronic timing stage as soon as a control signal is triggered by a control device which reacts in any case when parking starts, for example the ignition switch. In this way, it is automatically ensured that the correct parking time can always be determined from the display value of the display without the driver having to perform setting operations when he has parked, such as is necessary with hitherto customary parking discs.

Title: Egg transporting device
Inventor: WEIDMANN ANDREAS
IPC: B65G11/12
Filed: 1983-07-23
Abstract: In order to prevent damage to eggs arising from the difference in height between a laying path (1) and a transport path (3), a two-armed bent lever (7) is arranged so as to be pivotable (9) between them, the upper arm of which comes to rest against the end of the laying path (1), while the lower arm comes to rest against the transport path (3) in the state of rest. An egg (5) arriving onto the laying path (1) on the one hand opens a discharge region (11) between the upper lever arm (7a) and the laying path (1), while at the same time the lower lever arm (7b) pivots upwards and reduces the difference in height in such a way that when the egg (5) passes through the discharging aperture (11), it can be taken up by the lower lever arm (7) with virtually no drop at all. The lever (7) then pivots back to the transport path (3), braked by means of a brake (15). <IMAGE>

Patent DE-3330298-A1 (DE)
Title: Tachograph
Inventor: DONNER BERND
IPC: G07C7/00
Filed: 1983-08-23
Abstract: For a tachograph having a cover which can be pivoted upwards and in which the cover bearing can be only slightly loaded, a device is proposed for relieving the cover bearing when the cover is open. In detail, a flexible strip (23) is provided which is held on the housing (1), on the one hand, and on the cover (8), on the other. The ends of the strip (23) are assigned clasps (24, 25) which, after the ends of the strip have been suitably threaded, can be inserted by hand into pouches (26, 27) integrally formed on the housing (1) and on the cover (8). This threading operation of the strip is selected such that the strip (23), which is under tensile stress when the cover (8) is open, presses the ends of the strip against the respective clasps (24, 25), thus preventing the strip (23) from being extracted from its relatively loose fastenings. <IMAGE>

Patent DE-3341082-A1 (DE)
Title: Emergency running device for wheels, in particular motor vehicle wheels, with pneumatic tyres
Inventor: KAPPLER DIETER
IPC: B60C17/00
Filed: 1983-11-12
Abstract: The invention relates to an emergency running device for wheels, in particular motor vehicle wheels, with pneumatic tyres. It comprises a belt which has a tread profile on its outside and can be fixed on the tread of the tyre with parts of connecting elements arranged at its ends. A channel which extends over essentially the entire length of the belt in the centre, is enclosed at its ends and can be connected to a compressed air source by means of a valve and whose channel wall which rests against the cover of the tyre is constructed so as to be stretchable is provided on the inside of the belt. If the channel is pumped up after the belt is placed on the tread of the tyre, the cover of the tyre is pressed into the base of the rim by the bead which is formed during this process and is held in contact with the circumferential surface of said base. Thus, during driving, a volume of gas which is capable of bearing the vehicle and of elastically absorbing relatively small impacts remains present in the air channel despite the loss of air in the tyre.
Patent DE-3341507-A1 (DE)
Title: Tool for honing bores or shafts or the like
Inventor: GOETZ MANFRED
IPC: B24B33/08
Filed: 1983-11-17
Abstract: Honing tool for internal or external cylindrical surfaces, with a supporting basic body (10) and a clamping bush (36) which is connected in an oscillating manner to this basic body (10) and is provided with a conical clamping surface (52) for an elastically expandable supporting sleeve (54) which carries the honing sticks (58). An adjusting nut (28) supported on the basic body (10) or the clamping sleeve (72, Fig. 4) acts via a distance piece (31) on the supporting sleeve (54) for clamping on the clamping bush (36), as a result of which the supporting sleeve (54) is widened to the desired working diameter. Compared with a hydraulic expanding system, this mechanical construction has the advantage that the clamping forces are absorbed by the basic body (10) at least in the working area of the tool, which results in greater freedom of oscillating motion of the supporting sleeve (54). In addition, the supporting sleeve (54) can be of split construction, which results in a greater expanding range. <IMAGE>

Patent DE-3423598-A1 (DE)
Title: Device for closing vibration dampers
Inventor: WOESSNER FELIX DIPL ING
IPC: F16F9/32
Filed: 1984-06-27
Abstract: According to the invention, a device for closing vibration dampers, gas-filled springs or similar piston-cylinder units, which results in a high prestress between a cylinder arranged in a container when the unit is closed by flanging or partial pressing in of the container end or by roller seam welding, is obtained by virtue of the fact that, during the closing operation the container is held fixed axially in the upper cylindrical region of the container by a fixing device. As a result, the portion of the container below the fixing region is subjected to tension by the pressure exerted on the cylinder via the piston-rod guide. The cylinder itself is subjected to compression, with the result that the axial force applied is more or less retained as a prestressing force after closure.
