Patent DE-3216754-A1 (DE)
Title: Sensor for illuminating a measuring surface and for detecting radiation reflected from said measuring surface
Inventor: LORENZ ARTUR
IPC: G02B6/38
Filed: 1982-05-05
Abstract: The invention relates to a sensor having light guides (optical fibres) for illuminating a measuring surface and for measuring the radiation reflected from said measuring surface. The one ends of the light guides are arranged parallel to the measuring surface; a portion of the light guide serves to illuminate the measuring surface, and another portion to receive the reflected radiation. In known sensors, the end faces of the light guides that are adjacent to the measuring surface are ground at an angle of 90 DEG  to the longitudinal axis, so that the light coupled into the illuminating light guides is emitted perpendicularly onto the measuring surface and the reflected radiation is coupled vertically into the receiving light guides. In the case of this design, surface reflections feature in the measurement, giving rise to incorrect measured values of colour density. According to the invention, the influence of surface reflections is avoided by arranging for the end faces (7) of all the light guides which face the measuring surface to have an oblique polished section with a polished-section angle ( alpha S) which is larger than the critical angle ( alpha G) of the propagation of light inside the light guide. <IMAGE>

Title: Control time control system for two-stroke engines with rotary disc valve timing
Inventor: LIEBERT HEINZ
IPC: F01L7/06
Filed: 1982-09-13
Abstract: The invention relates to a device for varying the inlet cross section and the timing of the inlet which occurs due to a displacement by means of a plate between rotary disc valve and engine housing, in order to be able to utilise the fuel even better and in order to reduce the excess fuel with a constant contrtol time and/or a constant inlet cross section which occurs in different speed ranges. This object is met by a plate referred to above, whose drive is a centrifugal clutch or a computer-controlled drive section and is transmitted by a deflection mechanism (fig. I, F and A) which results in the inlet opening time being extended or shortened, the cross section enlarged or reduced. By means of the invention a fuel-air mixture is drawn in which the engine burns without having to give off unburnt fuel-air mixture. Fuel consumption is reduced. The device which has a hub is supported on the crankshaft journal. A retaining ring E prevents excessive axial play. <IMAGE>

Title: Process and bending press for the bending of a straight pipe to form a pipe bend with connected straight legs
Inventor: KOENIG RUDOLF DR ING
IPC: B21D7/06
Filed: 1982-12-21
Abstract: Process and bending press for the bending of a straight pipe to form a pipe bend with an opening angle of less than 110 DEG , in a pipe section between legs which are straight after the bending operation, by means of bend-pressing. In the process, the straight pipe is introduced with the pipe section to be bent, heated to bending temperature, into the bending tools of a bending press having a pipe-bend female die assigned to the convex pipe-bend side and a pipe-bend male die assigned to the concave pipe-bend side. Between the pipe-bend female die and pipe-bend male die, the pipe is bent in a plurality of press-stroke steps to form the pipe bend. In the first press-stroke step, the straight pipe is bent to an opening angle of approximately 120 to 110 DEG . Thereafter, the pipe section held between the pipe-bend female die and pipe-bend male die is upset with the effect of thickening the pipe wall, specifically by means of upsetting forces which are exerted via the straight legs. Subsequently to this, the upsetting forces are cancelled and the upset pipe section is bent further by means of the pipe-bend female die and pipe-bend male die, and, if necessary, so on and so forth in renewed alternation between upsetting and bending until the finished pipe bend with an opening angle of less than 110 DEG  is obtained. The bending press for carrying out this process possesses a clamping device for the legs, which is guided in the bending plane on arcuate guides and which, moreover, is designed as an upsetting device. <IMAGE>

Filed: 1983-11-02
Abstract: A job strip encoding printing process data is disposed on an indicia-free zone of an associated printing plate. The printing process data include process control data, press presetting data and organization data for the entire print order using the associated printing plate. Preferably, all of the important printing adjustments are computer controlled and the printing machine includes a scanner for automatically reading the job strip when the printing plate is clamped onto the plate cylinder of the printing machine. The job strip is not integral with the printing plate so that the printing process data are easily changed. The job strip, however, is attached to the printing plate and therefore the printing process data and associated printing plates are not mixed up in the print shop. The job strip is elongated and aligned parallel and adjacent to a longitudinal edge portion of the printing plate which is clamped to the plate cylinder. The job strip is circumferentially displaced from but located close to the area of the printing plate which is capable of printing and which engages the blanket cylinder, so that the inking rollers roll over the job strip during printing to keep it clean for scanning.

Title: Tread transmission with non-uniform transmission ratio, in particular for bicycles and other vehicles and home exercise equipment with leg-powered drive
Inventor: GREIFENBERG MICHAEL
IPC: B62M9/02
Filed: 1984-02-09
Abstract: The tread transmission with non-uniform transmission ratio serves to convert non-uniform rotations of the tread cranks into uniform rotations of the power output chain wheel. The features of the tread transmission are two coaxially mounted tread crankshafts 1 via which the chain wheel 17 which is attached to a power output hollow shaft 6 is driven via an auxiliary shaft 2. Here, the auxiliary shaft is driven by means of two pairs 3; 4 of ellipsoidal gear wheels, in each case one eccentrically attached ellipsoidal gear wheel intermeshing with a counterwheel attached on the respective tread crankshaft. The ellipsoidal gear wheels on the auxiliary shaft are offset in their eccentricity by 180 DEG . As a result, an inversely proportional change in the angular speed of the two tread crankshafts is produced. The power output to the power output hollow shaft 6 is effected via a pair 5; 7 of end wheels. The ellipsoidal gear wheels are replaceable. <IMAGE>

Title: Device for flame-hardening the internal surface of a pipe
Inventor: ESSER ALEXANDER
IPC: C21D9/14
Filed: 1984-03-22
Abstract: For flame-hardening the internal surface of a pipe, it is known to rotate the pipe and to pass a burner as well as a quenching rose, following the burner at a distance, non-rotatably through the pipe. However, this involves non-uniform hardening conditions, because the water jets emerging from the quenching rose do not uniformly wet the internal surface. To avoid these disadvantages, the invention provides a quenching rose 6 which rotates simultaneously with the pipe 1 in the same direction of rotation. For this purpose, a gear arrangement 8 can be provided which is connected to the rotary drive of the pipe 1. However, the quenching rose 6 can also be clamped to the pipe 1 in such a way that, although it is taken along by the pipe 1 in the circumferential direction, it is readily relatively displaceable in the longitudinal direction. If appropriate, the burner 4, alone or together with the quenching rose 6, can also rotate in the same direction of rotation simultaneously with the pipe 1. <IMAGE>
