Title: Device for determining the play on motor vehicle wheels
Inventor: GAISER GERMAN
IPC: G01B5/14
Filed: 1984-01-27
Abstract: The device is constructed in such a way that one support plate 2 has two working cylinders 9 and 10, so that movements in the axial direction and in the longitudinal direction of the vehicle are possible, while the other support plate 1 has only one working cylinder 8 for movement in the longitudinal direction of the vehicle. In this case, the arrangement is such that as a rule it is always only one of the support plates which executes a movement in one direction. The design is thereby greatly simplified and can also be better surveyed with regard to the mode of operation. <IMAGE>

Patent DE-3422190-A1 (DE)
Title: Configuration for determining surface defects on ferromagnetic material
Inventor: HALTER EUGEN DIPL PHYS
IPC: G01N27/84
Filed: 1984-06-15
Abstract: Use is made of the known method of marking surface defects with the aid of the leakage flux/magnetic powder method, the material being magnetised and magnetic powder being applied while one or more light sources are used to illuminate a selected section of the material to be tested and an optical evaluation device assigned to this section. At relatively little cost, effective recognition of marked surface defects is made possible by arranging, between the light source and the ferromagnetic material, a polariser to generate linearly polarised light and by placing a polarisation filter upstream of the optical evaluation device. The magnetic powder used does not have to be fluorescent, so that tests are economically feasible even at high temperatures (400-600 DEG C).
Patent DE-3422640-A1 (DE)
Title: Circuit arrangement for correcting the group delay of an RF signal frequency band to be transmitted
Inventor: SCHIMMEYER RICHARD
IPC: H04N5/14
Filed: 1984-06-19
Abstract: A circuit arrangement for correcting the group delay of a video signal frequency band to be transmitted contains a radio-frequency signal circuit, for example a demodulator circuit, which operates in push-pull mode and contains two push-pull outputs (2 and 3). One push-pull output (2) is connected to the output (4) of the circuit arrangement via a series resonant circuit (5) which is tuned to a frequency above the frequency band to be transmitted. The second push-pull output (3) is connected via the drain-source path (6) of a field effect transistor (7) to the output (4) of the correction circuit arrangement. The drain-source path (6) represents an ohmic resistance which can be adjusted by a DC voltage (US). The slope of the frequency-dependent characteristic of the group delay of this circuit is modified constantly in positive and negative directions through adjustment of a DC voltage value (US) at the control input (9). Effective correction of undesirable group delay distortion is thus possible with little control and circuit cost. <IMAGE>

Patent DE-3424014-A1 (DE)
Title: Photographic camera with automatic focusing
Inventor: BELITZ FRITZ DR
IPC: G03B3/04
Filed: 1984-06-29
Abstract: A photographic camera with automatic focusing is described in which, by contrast with similar cameras according to the prior art, it is not the lens but the film guide which is displaced for focusing purposes. Displacement of the film gate is effected by providing a plurality of, preferably 4, spindles which are parallel to the optical axis and engage in correspondingly provided threaded bores of the film guide. For the purpose of focusing by displacement of the film guide, the spindles are rotated synchronously, resulting in displacement of the film guide from a limit position in the direction of the optical axis. This displacement is stopped as a function of the distance measurement by providing electromagnetically actuated locking means which drop into the mechanism when focusing has been achieved. Said mechanism is connected kinematically to the cocking axis of the camera in such a way that upon the next film transport and shutter cocking the entire mechanism, and thus also the film guide, are returned to their initial position.

Patent DE-3430495-A1 (DE)
Title: Outflow regulator for fluid tanks
Inventor: SCHOELL STEFAN
IPC: G05D7/01
Filed: 1984-08-18
Abstract: An outflow regulator for fluid tanks is designed so as to float on the surface with a constant immersion depth and has at least one restrictor whose outflow cross-section is adjustable. As a result, the adjustment of the immersion depth required for conventional regulators becomes unnecessary. Advantageously, the restrictor is designed so that its height is adjustable with respect to the float, for example as a slide valve. A baffle surrounding the outflow ensures trouble-free operation by keeping out dirt.

Patent DE-3447476-A1 (DE)
Title: Allocation device for elongate material
Inventor: AIGNER JOSEF
IPC: B65G47/29
Filed: 1984-12-27
Abstract: This allocation device (3) operates with a rotating conveyor chain (FK). Tree trunks (2), which are to be allocated to a topping installation (7), are detained by stoppers (3a, 3b, 3c) until the topping installation (7) is ready to receive the next tree trunk (2) for processing, then the tree trunks (2) are fed in succession to the topping installation (7) or passed on to the subsequent stopper (3a, 3b, 3c). The stoppers (3a, 3b, 3c) have supporting tables (5a, 5b, 5c) which, with the aid of hydraulic drives (4a, 4b, 4c), raise the tree trunks (2) in the waiting position of the conveyor chain (FK), so that damage to the stationary tree trunks (2) by the rotating conveyor chain (FK) is avoided. <IMAGE>
Patent DE-3500296-A1 (DE)
Title: Pulsator for milking machines
Inventor: WILLACH EBERHARD DIPL ING
IPC: A01J5/12
Filed: 1985-01-07
Abstract: The pulsator is provided with two damping chambers 2, 3 which are connected to one another via the channel 4 and a restrictor 7. The pulsation frequency is dependent on the flow resistance in the restrictor 7. The flow resistance is generated by a ring-segment channel 8 in a rotatable disc 9 which is mounted with the ring-segment channel 8 on the planar surface 10 in a sealing manner. The ring-segment channel 8 is in direct connection with the channel 4 and, via the bore 6, with the first damping chamber 2. Rotation of the disc 9 effects an angular displacement between the channel 4 and bore 6. The effective length of the ring-segment channel 8 between the channel 4 and bore 6 is dependent on the size of the angle. Since the flow resistance of a flow channel increases in proportion with its length, a sensitive adjustment of the pulsation frequency can be carried out by rotating the disc 9. <IMAGE>

Patent DE-3505453-A1 (DE)
Title: Winding of yarns by random winding with breathing
Inventor: MARTENS GERHARD DR
IPC: B65H54/06
Filed: 1985-02-16
Abstract: Breathing takes place during the winding of yarns by random winding. In this, the traversing stroke is repeatedly shortened at both ends and then returned to its original value. The original value corresponds essentially to the bobbin length. To solve particular winding problems, the traversing stroke, after being shortened, is not returned to the original value again, but to an intermediate value. The contractions occurring thereby between two breathing strokes form the starting point for a new shortening. The breathing strokes can remain constant in spite of the contraction previously carried out.

Patent DE-3512104-A1 (DE)
Inventor: WAHNSCHAFFE JUERGEN
IPC: F02F1/10
Filed: 1985-04-03
Abstract: Each cylinder of a liquid cooled in-line internal combustion engine includes a cylinder pipe surrounded by an annular cooling chamber. The cooling chambers are interconnected in series by crossover passages between adjacent cylinder pipes and the cooling chambers have a greater cross sectional flow area on one side of the longitudinal central plane of the engine than on the other side. This cross sectional flow area relationship is reversed from cylinder to cylinder to thereby cause a meandering course of flow for a portion of the coolant thereby assuring adequate flow around the entire surface of the cylinder pipe and good flushing of the crossover passages between the cylinder pipes.

Patent DE-3517185-A1 (DE)
Title: Oil dipstick
IPC: F01M11/12
Filed: 1985-05-13
Abstract: A known dipstick for checking the oil level in motor vehicle engines comprises a steel rod flattened at the bottom end on at least one side, which is removably inserted into a filler neck of the oil sump. Oil level markings are applied on the flattened longitudinal section. For checking the oil level the dipstick must be drawn out of the filler neck, cleaned, re-inserted into the filler neck as far as the stop and finally drawn out again. The oil level can be determined from the wetting on the flattened longitudinal section. This process is time-consuming, irksome and carries the risk of getting oneself dirty. A guide tube with float is now provided. The guide tube remains constantly in the filler neck of the oil sump. The float is connected by way of a fibre glass line to a position sensor which slides in a transparent graduated cylinder on the upper end of the guide tube. The position sensor indicates the respective oil level without removing the dipstick. <IMAGE>
