Filed: 1972-07-29
Abstract: 1436124 Photo-electric blemish detectors FERRANTI Ltd 26 July 1973 [29 July 1972] 35610/72 Heading G1A Blemishes in opposite faces of a moving substantially planar object or web are detected by a system in which a beam of radiation is scanned across the edge of the object or web in a perpendicular plane and is directed by reflectors arranged adjacent to the opposite-faces so that these are scanned in turn and the radiation diffusely reflected from the object is applied to a detector. In a first embodiment, Fig. 2, the beam from a laser 2 is directed via a focusing system 3 on to a mirror drum 5. The web 10 is moved longitudinally between two mirrors 8, 9 so that opposite sides of the web are alternately scanned in opposite directions during each sweep of the beam. Diffusely reflected radiation is passed via mirror 8 or 9 as appropriate and mirror 6<SP>1</SP> to a detector 6. In a modification for use with narrow webs a plurality of pairs of reflective surfaces are arranged side by side with a web running between the surfaces of each pair so that a single sweep of the beam from the mirror drum is directed so that both sides of each web are scanned in turn, Fig. 3, (not shown). In a further arrangement Fig. 4, (not shown) a plurality of narrow webs or objects are transported in a coplanar manner between a pair of mirrors so that the mirror drum sweep results in a scan across one face of each web followed by a scan in the reverse direction and order across the opposite faces of the webs. The mirrors may be angled in such a way that the reflected beams can be received by a second pair of mirrors for direction of the radiation back to the detector so that light scattered from the mirror surfaces can not directly reach the detector Fig. 5, (not shown).

Abstract: 430,824. Automatic exchange systems. FULD & CO. TELEPHON-UND TELEGRAPHENWERKE AKT.-GES., 134, Mainzerlandstrasse, Frankfort-on-Main, Germany. Dec. 21, 1933, No. 36027. Convention date, Dec. 21, 1932. [Class 40 (iv)]. Relates to impulse-repeating arrangements involving the use of the charging or discharging circuit of a condenser and comprises several such arrangements for converting faulty impulses or for changing the frequency of the impulses. In one arrangement, Fig. 1, the impulse-responding relay J connects relay M in the charging circuit of condenser C and M completes a holding circuit for itself to ensure that it will be fully operated even if the original impulse is not in itself long enough. When the condenser is fully charged, M releases and the condenser discharges through resistance w. In another arrangement, Fig. 2 (not shown), the condenser is normally charged and discharges through M at each impulse, and a front contact of M holds J operated. In a third arrangement, Fig. 3, too-short intervals between impulses are corrected by arranging that J cannot re-operate as long as M is operated for the previous impulse or during the discharge of condenser C which takes place through an opposing winding (ii) of J. The holding circuit for M includes a resistance w designed so that the decreased charging current is compensated by the increase in the time of charging. In a fourth arrangement, Fig. 4, the relay M and condenser C are directly in series so that M is operated twice for each impulse. A further arrangement, Fig. 6 (not shown), is designed so that M is operated only once for each two impulses. The size of the condensers, which are preferably electrolytic, may be reduced by arranging that the polarity is reversed at both ends at each charging and discharging operation.

Title: Improvements relating to apparatus for conveying pulverulent or quasi-liquid material from a tank by means of compressed air
IPC: B65G53/12
Filed: 1935-12-31
Abstract: 468,225. Conveying pulverulent and semi-liquid materials. JORGENSEN, M. VOGEL-. Dec. 31, 1935, No. 36098. Addition to 460,778. [Class 102 (ii)] In apparatus for discharging pulverulent or semi-liquid material from a container by compressed air, in which the valves are operated under the control of electric condensers or photo-electric cells as described in the parent Specification, the lower control unit is situated in the discharge pipe, or is partially formed by the discharge pipe. As shown in Fig. 1, the end 23 of the discharge pipe is insulated at 27 from the remainder of the pipe and is connected by an insulated conductor 26 to a terminal 24. A ring 15 and the member 23 form the inner plates of condensers which control the material valve 10 and the compressed air valve 12a, the outer plates being formed by the container 1. The arrangement of the circuit is shown in Fig. 4, in which 43 represents the upper condenser and 44 the lower condenser. The condensers are arranged in parallel in the circuit of a transformer winding 46, which is energized by a winding 45 in the main circuit. The circuits of the condensers 43, 44 are controlled by switches 38, 37, which are moved by a solenoid 39 simultaneously with switches 36, 35 controlling the circuits of solenoids 11, 13, which open the valve 10 or the valve 12a against the action of springs. When, during filling of the container, the material rises above the upper condenser, the current in the circuit through the condenser 43 and switch 38 increases and a relay 41 closes a switch 40, thus energizing the solenoid 39, so that the valve 10 is closed and the valve 12a opened. The switch 40 is held closed by current through the condenser 44 and the switch 37 until all the material is discharged from the container, when all the switches are reversed owing to failure of the current in the relay 41. In a modification, one condenser plate is arranged inside the discharge pipe, the pipe forming the outer plate. In this case the operation of the switches 38, 37 is delayed by a time relay. In a further modification, the condensers are replaced by photoelectric cells. The valves of one container may be controlled from another container, as described in the parent Specification.
