Title: Improvements in methods of and apparatus for measuring the cloudiness of travelling paper webs
IPC: G01N21/86
Filed: 1966-06-17
Abstract: 1,129,536. Photo-electric measurement of paper web formation. VALMET OY. June 17, 1966 [Oct. 19, 1965], No.27069/66. Heading G1A. The "cloudiness" (sheet formation variations) of a travelling paper web is measured by detecting light transmitted through the web to produce a signal having D.C. and A. C. components, the ratio between which is indicative of the cloudiness of the sheet. In one arrangement, Fig. 1, light from a source 2 is transmitted by the web to the detector, a photo-multiplier 4. The D.C. component is measured by a milliammeter 5 and the A. C. component by an A. C. meter 7 across the fixed resistor 6. The quotient of the components in percentages is read on a meter 8. In a second arrangement, Fig. 2 (not shown), the meter 5 of Fig. 1 is replaced by a device (9) which controls an aperture stop (3) located in front of the detector (4) the D. C. component being maintained constant thereby. In this case, the cloudiness of the sheet formation is measured direct from the meter(7), meter 8 being omitted. The ratio measured is U m /#U where U m  denotes the root mean square of the instantaneous value of intensity transmitted by the web, above or below the average transparency of the paper U (the D. C. component). The sensitivity of the apparatus is adjustable to deal with different grades of paper. By frequency analysis of the detector output, floc size distribution of the paper may be investigated.

Abstract: 706,649. Extruding. SIEMENS-SCHUCKERTWERKE AKT.-GES. Nov. 19, 1951 [Nov. 20, 1950], No. 27126/51. Class 83 (4) In a method of extruding electric cable sheaths, solid blanks introduced into the receiver of a press are heated to extrusion temperature in the receiver. A press in which a sheath is extruded from a receiver 14 over a cable core passing through a mandrel 11 has an induction heating coil 16 surrounding the pressing chamber 15 of the receiver 14 to heat the sheathing material as it is fed to the die 10. Alternatively a heating coil may be placed in the central core about which the metal flows or direct current heating means may be employed. Temperature detection in the heating zone may be used to regulate the output of the coil 16. The heating coil and various parts of the press may be insulated from each other by heat resisting inserts and parts of the press may be cooled. Tubular blanks divided longitudinally are placed round the mandrel support 12 and extruded by a hollow ram 13 on a plunger 2. The head 3 for the die 10 is connected to the main head 1 of the plunger 2 by tie rods 6. The receiver body 5 is held against the head 3 by hydraulic plungers 8 which may be actuated to lift the body 5 away from the head 3 to permit access to the mandrel 11 and die 10.

Abstract: 989,877. Converting. G. NIEMOLLER. July 28, 1961 [July 28, 1960], No. 27460/61. Heading H2F. [Also in Division H1] A pulse producer for electrified fences has a transformer whose secondary winding 2 is connected with one terminal 22 to earth, and the other terminal 21 to the fence, and whose primary winding 1 attracts armature 4 which is resiliently biased by spring 5 arranged to push rod 7 and so operate a micro-switch (shown for clarity as a leaf spring 14) which breaks the connection between the primary winding 1 and the battery 18 whereupon the armature 4 is returned to its initial position by spring 5. The rod 7 also drives piston 8 into cylinder 9 against spring 10. When the armature returns, the piston 5 also returns to its former position, turning on the switch 17, in a time determined by the air inlet throttle 13. The pulse producer, being cheap, may be combined with a dry battery and the whole assembly thrown away when the battery is exhausted, or fitted on to a housing with the battery and a pilot light.

Title: Automatic headlight dimmer and glare shield
IPC: B60Q1/14
Filed: 1938-09-20
Abstract: 518,593. Photo-electrically controlled head-light dimmer and glare shield. RONNING, A. Sept. 20, 1938, No. 27462. [Class 40 (iii)] [Also in Groups XXXII and XXXVII] An automatic head-light dimmer and glareshield is controlled by a heat actuated control switch itself controlled by a photo-electric device. As shown in Fig. 8, the apparatus is enclosed in a casing 10 with a lid 11, and comprises various parts as follows. A lightsensitive cell in the form of a coated disc 15 is disposed between contact fingers 17, 19 behind a glass window 22. The contact fingers 17, 19 are connected to the moving coil 29 of an electric instrument having a horse-shoe magnet 37 fastened to the casing. The spindle 28 of the moving coil carries a disc shutter 44 provided with an aperture 50. When the light-sensitive cell receives light from an approaching vehicle, the current generated causes the shutter 44 to bring its aperture 50 in line with an aperture 51 in a screen 48, and heat radiated by an electrically heated coil 52 and reflected by a reflector 57 can then pass to a thermal switch 59, 60, 61. When no heat strikes this switch, contact 61 is away from contact 60 and in contact with contact 59 ; and in this position of the switch the bright filament G, Fig. 5, of a head-light D is in circuit. But, when heat strikes the switch, contact 61, which comprises a bi-metallic structure, leaves contact 59 and touches contact 60. This cuts. off the bright filament G and puts the dim filament H in circuit. At the same time, current passes to a coil 81, which causes a permanent magnet 78 to rock with a shaft 77 carrying a glare shield, thereby swing- ing this shield in the line of vision of the driver. The casing of the apparatus may be attached to the wind screen by means of a rubber ring coated with adhesive, or may be mounted on a hinged bracket permitting adjustments of position and direction.

Title: Improvements in or relating to fault detection circuits

Abstract: 919,241. Transistor pulse circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 24, 1961 [Aug. 13, 1960], No. 28092/60. Class 40 (6). [Also in Group XXXVI] In a circuit for monitoring a normally continuous train of regularly occurring pulses, the pulses are applied to a static switch over two parallel paths, one including a circuit which delays each pulse by one pulse period so that if the train ceases or a pulse is omitted from the train or the P.R.F. is wrong, concurrent pulses are not applied to the switch and an alarm or disabling circuit is thus operated. In the Figures, positive-going " clock " or synchronizing pulses obtained from a data processing magnetic drum are received at OL (Fig. 1) and is applied to a path comprising in cascade, a transistor TX6, a first flip-flot circuit TX1, TX2, a second flip-flop TX3, TX4, a differentiator C 4 , R 9 , and an amplifier TX5, the path providing a delay of one pulse period. The transistor TX6 also feeds a second path comprising a flip-flop TX7, TX8 acting as a pulse widener but not producing a delay. The outputs from the two paths are applied respectively to the base and emitter of a transistor TS9 arranged such that the presence of the underlayed pulse at the emitter will prevent the delayed base pulse passing to the collector. If, however, a pulse is missing from the input train or the train ceases or is of the wrong frequency an undelayed inhibiting pulse will not be applied to the emitter and the delayed pulse applied to the base will appear in the collector circuit and will trigger a bi-stable circuit TX11, TX12. This will cause a transistor TX10 to become conductive to operate an alarm lamp LP and will apply a voltage from the collector of TX12 to the output line L2 to disable the recording head circuits. The widening of the input pulses by flip-flop TX7, TX8 allows for changes in delay due to supply voltage changes. In addition, transistor TX6 is biased so as not to pass input pulses of less than a predetermined amplitude and a gate D9 will pass pulses to the bi-stable circuit only if they exceed a further predetermined level so that both these conditions will also cause operation of the alarm. The alarm may be reset by operating a key K1. Specification 909,205 is referred to.
