Title: Web control system
IPC: B65H23/185
Filed: 1967-12-04
Abstract: 1,214,846. Automatic registration. J. BOBST ET FILS S.A. Dec.4, 1967 [Dec.7, 1966],  No.54984/67. Heading G3R. In a system for automatically correcting longitudinal registration of a moving web, correction is effected in dependence on the sum of electrical signals derived from a web radiation scanner proportional to registration error and its integral. In Fig. 1, a pre-printed web 80 is drawn from a roll 82 and passed to a rotary device 84 for further printing, e.g. in a different colour, or cutting. Longitudinal registration is detected by comparing at 88 the position of marks printed on the web, as detected by a photo-electric scanner 86, with the pulse output of a phase micrometer 90 driven with device 84. A signal proportional to any error is amplified at 98, has its integral added by an electrolytic integrator 100, and is further amplified at 102, 104 to control the energization of a magnetic brake 108 associated with roll 82 in such sense as to correct the error. Modifications are described in which (a) the magnetic brake is associated with a drag roll in a loop formed in the web between supply roll 82 and rotary device 84 instead of with the supply roll 82. The position of a roll forming the loop may then be adjustable for setting correct registration initially. (b) correction of registration is effected by a servomotor, controlled by a silicon controlled rectifier, which adjusts, through a differential gear, the speed of rolls engaging the web between supply roll 82 and rotary device 84, instead of by varying the energization of a magnetic brake.

Title: Method for detecting organic biodegradable pollution and  apparatus therefor
IPC: G01N33/18
Filed: 1970-11-20
Abstract: 1329440 Electro-chemical analysis OMNIUM D' ASSAINISSEMENT 20 Nov 1970 [21 Nov 1969] 55227/70 Heading G1N A method of determining the organic biodegradable pollution of a liquid comprises (i) making an electro-chemical measurement of the variation in oxygen content over a period of time (and hence the oxygen consumption per unit time) (ii) repeating the measurement after the sample has been oxygen enriched (iii) noting the variation in consumption over successive periods. In one arrangement Fig.4, a measuring cell 1 is connected to a recorder 15, and supplied with samples from an oxygen enrichment tank (aereator) 4 by a pump 8. The recorder is provided with limit contacts d 1 , d 2 , and when the oxygen content reaches a level d2 (point a on Fig.7,) the pump is stopped. When the transitory disturbance has finished, (arbitrarily determined by a slightly lower oxygen level dl), a timer is started for the measuring period. At the end of the predetermined time interval, point c, the pump is started for a further cycle. The oxygen consumed during the timed interval equals b-c. Alternative constructions:- (i) enriched sample may be supplied by gravity with solenoid controlled valve (12) replacing the pump Fig. 5 (not shown). (ii) air (or oxygen) may be admitted to the test cell for enrichment Fig.6 (not shown). (iii) a variable volume container may be used Figs.12, 13, (not shown) comprising an elastic "sleeve" which can be expanded by vacuum to fill a surrounding tank (so that a longer reaction time is provided for liquid flowing through the enlarged "sleeve". Alternative circuits:- block diagram circuits are described in which Fig. 8 (not shown) threshold detectors (D1, D2) replace the limit switch d1, d2 to control a logic circuit in conjunction with the timer contact (Te) whereby (i) the value C is locked in a memory during the next cycle and (ii) the enrichment pump is started. With the variable volume construction contacts may be operated to gate memory circuits in synchronism with the expansion and contraction of the "sleeve" , whereby the difference in oxygen concentration is determined, Fig.15 (not shown) or in Fig.16 a threshold circuit CD may gate the memories M1, M2 to store the peaks and troughs from the sensor circuit to feed to the subtractor CS.

Abstract: 1,150,460. Roller assembly and heating block for filaments. BARMAG BARMER MASCHINENFABRIK A.G. 13 Dec., 1966 [14 Dec., 1965], No. 55685/66. Heading B5B. A device comprising two rollers, and a filament heating block between them adapted to act as a detector of the unwanted wrapping of the filament round one of the rollers, such as is liable to occur in the event of filament breakage, comprises a positively driven godet 1 (Figs. 1 and 2) a freely rotatable guide roller 3 whose axis of rotation is, as is usual, at a slight angle to that of the godet or main roller 1, and a heating block 4 fixed on a spindle 5 pivotably mounted in a bush 6 fixed in the front wall 2 of a machine frame 2. The filament or yarn travels in a series of helical loops round the godet 1 the guide roller 3 and the heated surfaces 22 of the heating block 4 which is thermostatically maintained at a predetermined temperature by internal electric heating elements 7. The faces 23 and 24 of the heating block 4 adjacent to the rollers 1 and 3 (Fig. 1) are concave to conform to the peripheral surfaces of the rollers and in the normal operative position of the heating block the clearance between block and the rollers are small and wedge shaped and taper in the direction of rotation of the rollers. If the yarn breaks and wraps itself round the godet 1 and/or the roller 3, as soon as the layer of laps on either or both rolls becomes thick enough to rub against the heating block 4 in the narrow part of the wedge gap, the heating block pivots in a direction opposite to the direction of rotation of the rollers and actuates a switch 19 (Fig. 3) which releases a yarn cutter (not shown). Optionally the actuation of the switch may stop the drive of the godet 1 or of the machine and may also cut off the power supply to the heating block. One end 8 of a switch lever 12 is fixedly mounted in the spindle 5 of the heating block 4 and the lever 12 is urged by a spring 11 against a stop 13 adjustably mounted in a fixed support 14.

Title: Device for controlling the transfer of binary data from a plurality of data sources to a receiver common thereto
IPC: H04L12/40

Abstract: 1,216,023. Data processor interrupt system. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. 29 Nov., 1968 [29 Nov., 1967], No. 56839/68. Heading G4A. A device for controlling the transfer of data from a plurality of data sources to a receiver includes a shift register each stage of which interrogates a different source when the stage is set, each stage being set successively in a cyclic sequence, the sequence being interrupted if an interrogated source has data to transmit, each transmitting source proceeding the data by a binary address signal permanently associated therewith regardless of the position of the source with respect to its interrogating stage in the register. A signal I1 from a controller sets a stage X3 in a register to enable an AND gate X5. A signal I2 allows the AND gate X5 to return an interrupt signal if a signal from OR gate X2 indicates that data is stored in register X1. An acknowledgement signal I3 enables AND gate X6 to cause the address of the source to be passed via diodes X7 to X9 to line 5 connected to the processor. A signal I4 enables AND gates Xal-Xan to pass data stored in register X1 to lines 5. An acknowledgement signal I5 from the processor clears the register X1 via AND gate X4 and if the stage X3 is not the last stage of the register the next stage is set. Each source and register stage are of plug-in construction to the wiring of the control device (6, Fig. 1, not shown) the wiring being arranged to recieve as many sources as required. The order of interrogation of the units can thus be altered by plugging into various positions in the register.
