Title: Method and device for determining the surface roughness and/or the surface structure of objects
Inventor: SCHWAB OTTO PROF DIPL ING DR
IPC: G01B11/30
Filed: 1987-02-05
Abstract: In order to examine the surface structure of objects, the surface (103) is scanned dot by dot with a light beam using an illumination source (105, 107). Stray light (118) is reflected by the roughness of the surface. A lens (110) which deflects a portion of the reflected light (118) onto the surface of a two-dimensional position-sensitive photodiode (111) is arranged offset with respect to the angle of reflection. The point (113) at which the light strikes the photodiode (111) provides information for example on the distribution of inclination of the microsurfaces of the surface (103) of the object (101). Since surfaces with different degrees of roughness scatter light to different degrees of intensity, the intensity of the difference signal acquired from the output signals of the photodiode (111) is a direct measure of the surface roughness of the object. <IMAGE>

Title: Football boot
Inventor: KLEPPER PETER
IPC: A43B5/02
Filed: 1988-01-29
Abstract: The invention provides a new football boot, in which, in the interests of avoiding fatigue phenomena during running and to achieve to the greatest possible extent natural/orthopaedic foot position with three-point support of the foot arch and the best possible guarantee of the natural deflection functions, the toe rays are, at least in the central foot region, received by the toe cap in such a manner that, in spite of bearing closely against one another, they exert no significant pressure effect on one another, at the same time the sole understructure being cambered with an inclination from the lateral side to the medial side. For the further fixing of the three-point support of the foot on the sole inner side, the heel region can furthermore be raised beyond the shaft end upper edge, it being possible expediently for an upwardly projecting, preferably cushioned tongue to offer protection for the Achilles' tendon region. A reinforcement of the toe cap serves to increase the shooting accuracy with a further protective function for in particular the central toe region, and a reinforcement of the medial side by a tab region drawn forwards from the heel region serves for stability. <IMAGE>

Patent DE-3827160-A1 (DE)
Title: Bag filter
Inventor: UFFELN HEINZ
IPC: B01D46/00
Filed: 1988-08-10
Abstract: The invention relates to a bag filter having a multiplicity of vertical filter bags through which the contaminated untreated gas stream flows over their entire length, or at least a significant part of their entire length, in the direction of the diameter so that the impurities deposit on the topside of the bag. The purified gas stream leaves the filter bags in an axial direction, while cleaning gas for cleaning the filter bags flows through the filter bags in the reverse direction at a higher pressure. The filter bags are combined into two bag groups, of which only the first bag group containing considerably more bags is connected to the untreated gas source and the receiver for purified gas, while the second bag group containing considerably fewer bags, instead of being connected to the receiver for purified gas, is connected to a source for cleaning gas. By means of a control element, at the end of a predetermined period, the second bag group is assigned stepwise to the first bag group of which, at the same time, from one up to the number of bags until then associated with it are combined to form a new bag group and their flow conditions are correspondingly altered (Fig. 3). <IMAGE>

At the same time it is proposed that the central fuel passage (20) and the carrier air passage (21) or passages in each injection line (13) be arranged separately from one another and designed in such a way that a fuel jet (22), surrounded by a blanket of air (23), is formed at the injection point. <IMAGE>
Patent DE-3827884-A1 (DE)
Inventor: SIGL ALFRED DIPL ING
IPC: B60K28/16
Filed: 1988-08-17
Abstract: In a fuel-metering system in the engine of a motor vehicle, an actuator, for example for the throttle valve, is adjusted in function of an electrical reference signal previously supplied by the driver. A desired wheel driving torque should, however, be predetermined by the driver. The reference signal is therefore converted, by means of a stored characteristic curve field, to a reference torque signal, which characterizes the position of the throttle valve that produces the desired driving torque under the instantaneous conditions (engine speed, gear).
