Title: Control mechanism for a zoom lens
Inventor: KOMINE YOSHIO
IPC: G02B7/08
Filed: 1981-05-20
Abstract: A description is given of a control mechanism for a zoom lens of the type in which a first lens cluster is used for compensating image shift (displacement) and for focusing, and a second lens cluster for varying the image magnification. The mechanism has a front lens tube, which holds the first lens cluster, a focusing cam device which co-operates with the range-setting element, an image compensation cam device which co-operates with the zoom operating element, and a control device which is arranged such that it changes its position in accordance with the two devices previously mentioned, the displacement of the control device being transmitted to the front lens tube via a connection.

Abstract: A haymaking machine with at least one rotary-rake unit driven in rotation about an upwardly directed supporting column, with a drive unit, likewise mounted rotatably on the supporting column, for the rotary rake, with an undercarriage connected fixedly to the supporting column, and with a control cam track which is fixed in a coaxial arrangement relative to the supporting column and which acts on control levers of tine carriers of the rotary-rake unit, in order to pivot tines at the ends of the tine carriers into or out of engagement with the ground, a releasable rotation lock being inserted between the supporting column and the drive unit for mutual retention in respectively one of two positions rotated through 180 DEG relative to one another, is further developed to the effect of a simple and reliable reversal of the tine engagement region. In particular, it is to be possible for the reversal to take place from the tractor seat during the change-over between forward travel and reverse travel. In this respect, a coupling, released in the state of rest, between the rotary-rake unit and the supporting column and a coupling actuation assigned to the coupling are provided.

Title: Tamping plate displacement drive
Inventor: STEGMANN HEINZ
IPC: C10B31/10
Filed: 1981-06-24
Abstract: Coking coal compacted by tamping operation is moved as finished coal cake, extending upright on the tamping plate, into the coke oven. This tamping plate is assigned a rack which is framed on the sides by flanks which end in a crest and/or slightly protrude beyond the latter. This rack meshes with a pinion in a fixed arrangement, which can be connected to the drive. Via the flanks formed as sliding shoes and with the aid of the rack drive, the tamping plate can be moved evenly into the coke oven, the driving pinion being advantageously arranged in such a way that, as compared with the hitherto conventional chain drives, sufficient room for a guard rail remains on the inspection gallery. <IMAGE>

Title: Method of building a bridge with flexible supports as well as displacement bearing for implementing the method
IPC: E01D19/04
Filed: 1981-07-14
Abstract: In the manufacture in sections of bridge superstructures in a manufacturing stand which is arranged in particular at one bridge end, and the advance of the superstructure (timed shifting), the supporting structures undergo horizontal deformations which, in particular in the case of flexible supports, can lead to damage to the superstructure and/or the supports. The invention describes a method, with which the stresses on the bridge components can be kept within the permitted limits in the case of flexible supports, and in which bearings are used which, adapted to the rigidity of the supports, act, under given limited tension and loading conditions, as articulated bearings and, in the event of these conditions being exceeded, as clamping devices. Also described are bearing constructions for implementing the method.

Title: Method and device for the determination of the squint angle between the mid-point axes of two eyes
Inventor: ROESSLER HERMANN
IPC: A61B3/113
Filed: 1982-02-24
Abstract: In the method, the optical axes of two optical recording devices and two reflex light sources are oriented toward the pupillary distance of the eyes in order to determine the squint angle between the mid-point axes of two eyes and to differentiate between real squinting and gamma-angle errors of the squinting eye. On alignment of the squinting eye with a fixing light to the allocated optical axis a light reflex is generated on the cornea with the allocated reflex light source and at the same time a horizontal eye half is photographically imaged with the allocated recording device on a horizontal half of an image plane. After alignment of the normal-sighted eye by means of a fixing light to the allocated optical axis the other eye half of the squinting eye is photographically imaged on the other half of the image plane with a light reflex produced once again. A real squint angle or, as the case may be, a gamma angle present can be determined from the light reflex position in the two imaged eye halves and the horizontal light reflex spacing relative to the optical axis of the imaging recording device.

Title: Circuit arrangement for combining a digital data signal and an associated clock signal to form a CMI-coded signal
Inventor: BECKER DIETER ING GRAD
IPC: H04L25/49
Filed: 1982-08-19
Abstract: In future broadband transmission networks for digital data signals such as digital television, radio, videotelephone, telephone and other data signals, owing to the physical distance between data sources and multiplexer and between demultiplexer and terminals, a special line transmission must be provided. The circuit arrangement according to the invention, shown in Fig. 1, essentially comprises two delay flip-flops (1 and 3), two AND elements (2 and 5) two NOR elements (6 and 8) and also an inverter (9). The delay elements (4 and 7) compensate for the differences in transit time of the signals to be processed in the AND element (5) or in the NOR element (8). If the circuit arrangement is constructed using ECL technology, signals can be processed up to in excess of 70 MHz. The boosting of the CMI-coded signal for transmission over distances of about 200 m is undertaken by a commercially available HF amplifier (10). An L-C high-pass filter (11) permits the coupling out of a relatively low-frequency control signal (S) arriving via the line (12). <IMAGE>
