Title: Measuring system for sensing track straightness - has light transmitter and image receiver sensing rail face distance
Inventor: WAGNER HERBERT A DR
IPC: B61K9/08
Filed: 1976-04-27
Abstract: The distance measuring device is mounted on a railway vehicle. It is used for measuring optically the distance between the measuring unit on vehicle and the upper or side face of each rail (8). This system analyses the relative position of two rails from the vehicle moving on the track and checks track straightness. The image projection focuses the image of a light source and aligns it along an axis intersecting the face of the rail. The reflected image is focussed in the receiver. The position of the reflected image is measured for the distance of the image projector from rail surface. The intersecting axis and optical axis are situated in a plane projecting along the rail. The reflected light receiver has photocells spaces in a direction across that in which the image is received. The image is projected, according to the change of the distance between the image projecting and rail face, on different photocells.

Title: Vibratory sieve for grading granular material - has plastics pads under wire mesh to reduce wear
Inventor: DRATWA HEINRICH DIPL ING DR
IPC: B07B1/46
Filed: 1976-06-04
Abstract: Vibratory sieves which are constructed of wire mesh are liable to suffer wear near the points of attachment of the rods which transmit the vibratory motion from the driving mechanism. This wear can be reduced by fitting plastic pads (b) under the wires (a) near the points of attachment. The pads are cast from plastic in wooden moulds. The moulds have a non-stick surface such as PTFEE and fitted under the wire mesh so that the pads (b) can be cast in situ. from low melting point polyester or polyamide. By using these pads the operating life of a sieve can be increased from one month to eight months.

Patent DE-2647229-A1 (DE)
Inventor: GRUEBNER KLAUS
IPC: G01C11/06
Filed: 1976-10-20
Abstract: The device exhibits a correlator (4) for processing the video signals (A, B) from image pick up tubes for scanning a pair of stereo images and a z tracking system for correcting the measurement marker in the z direction on the stereo model to be evaluated. To increase the performance of the stereo evaluating device, an operational amplifier (11) which can be set to several fixed gain factors and an analog multiplier (12) which provides for a continuous variation in the gain by means of a corresponding control voltage are provided which change the gain factor between the parallax error signal and the tracking signal occurring at the output of the image correlator (4). They thus compensate for fluctuations in the video signals generated from the measurement images. <IMAGE>

Title: Control system for product delivered in band form - esp. slurry in paper-making, giving uniformity automatically across width (SW 26.6.78)
Inventor: DOERFEL WALTER GERHARD
IPC: D21F1/02
Filed: 1977-03-07
Abstract: Arrangement for controlling the prodn. of a band or web of material has adjusting assemblies located in definite positions spaced out across the width of the band, side by side. These operate a mechanism which acts on the band across its width, and can be regulated so that the action of the mechanism can be varied locally across the width of the band. Arrangement includes a set of controlling organs, each of which can be moved separately, and is connected mechanically to an adjusting element, in such a way that the motion of the control organ displaces the adjusting element and alters the impact of the mechanism acting on the band across its width. Some, at least of the controlling organs are moved by a detail serving them in common. They can be coupled to this in response to a signal from a detector monitoring the position at a particular moment of each of the controlling organs. Detectors monitor characteristics of the band across its width, and the data is transmitted to a command station which puts out signals for coupling and uncoupling the different controlling organs and the common driving mechanism. Arrangement can be applied partic. to the control of the outlet of the slurry feed on a papermaking machine. It may also be used for humidifying paper, as well as for the application of a liquid to a continuous web of paper or cloth by means of an overflow sluice, the height of which is regulated automatically. The device can also be used in a hot calender to impregnating paper. Eliminates the tedious work, requiring skilled personnel, of manually adjusting the various mechanisms across the width of the machine. Adjustment is immediate and when the required motion has taken place the control organs are uncoupled and locked in place.

Title: Electrostatic duplicator with controlled exposure - has endless latent image and comparator circuits to examine level of charge
Inventor: URSO CHARLES J
IPC: G03G15/02
Filed: 1977-10-25
Abstract: An electronic circuit incorporated in an electrostatic duplicator examines the level of electrostatic charge of the latent image which is proportional to the light intensity of the image of the original received through the optical system. A comparator circuit compares the latent electrostatic image charge produced on the carried belt. A light source of veriable intensity is controlled by a screen of liquid crystal. An optimal level of electrostatic charge is calculated by examining whether or not the latent electrostatic image is over or under loaded by the electrostatic generator. The feed back circuit does not come into play unless a modification in the latent image is necessary. The belt is coated with selenium, hence made photosensitive. It is electrostatically charged by the generator connected to a power source. The belt moves along three guide rollers having their axes parallel to each other and rotating at constant speed.
