Title: Method and apparatus for winding tapered cross-wound bobbins with constant speed of thread supply
IPC: B65H54/28
Filed: 1975-11-20
Abstract: 1526446 Starting to wind tapered bobbins; maintaining thread tension W REINERS VERWALTUNGS - GmbH 20 Nov 1975 [20 Nov 1974] 47777/75 Headings DID and D1J To start the winding of a tapered, crosswound bobbin with constant thread-supply speed, a thread-reserve device which compensates for the variation in bobbin diameter is brought to a zero position where it contains thread, the thread is guided by an auxiliary thread guide to the point on the bobbin where the peripheral speed equals the thread-supply speed, and after release from the auxiliary thread guide the thread is caught by a traversing thread guide only when it is moving towards the bobbin small end. When handle 40 is raised, auxiliary guide 36 is raised to remove the thread from traversing guide 19 and guide the thread to the point on bobbin 16 where the peripheral and feed speeds are equal. At this point, the bobbin is driven by raised portion 15 on drive roller 14. Handle 40 also pivots yarn-reserve-forming lever 26 anti-clockwise to the zero position. When handle 40 is lowered, lever 26 is released and guide 36 is lowered so that shaped guide 19 picks up the thread when travelling to the smaller bobbin end.

Abstract: 1346219 Correcting read only memories SOC HONEYWELL BULL 14 Oct 1971 [16 Oct 1970] 47944/71 Heading G4A A memory system for a digital computer comprises a read only memory MP and an erasable updating memory MMJ which holds corrected data corresponding to erroneous data in the read only memory, the system being such that corrected data is read out in place of the erroneous data where appropriate. Memory MP is a microprogram memory (e.g. diodes or transistors in integrated circuits) which is controlled by an address register RA and feeds instructions through a switch MX to a processor PR. Register RA interrogates both memories simultaneously and memory MP feeds data to switch MX but this data is only transmitted to processor PR if it is correct. If it is not correct there will be corresponding correct data in memory MMJ, a signal on line 3 will block the incorrect data, and the correct data will be sent to processor PR in its place. The memory MMJ (Fig. 2, not shown) comprises an associative memory which holds the addresses of words in memory MP which hold incorrect data and an erasable memory which holds correct data, the latter memory being changeable by data from punched cards, tapes or discs.

Filed: 1973-10-23
Abstract: 1389359 Projectile fuzes DIEHL 23 Oct 1973 [13 Nov 1972] 49169/73 Heading F3A An electrical fuze for a projectile comprises: a capacitor (not shown), which upon target impact or after a maximum flight duration discharges to ignite an ignition element 39 armable during the flight. The ignition current circuit includes a switch pin 24 which after the firing of the projectile and the expanding of a centrifugal coil 30 is pressed by a spring 25 against a contact 40 of the armed ignition element 39. The capacitor is charged upon firing the projectile by an electromagnetic generator or by a piezoelectric element 20 compressible by an inertia plate 19. The capacitor is discharged by the triggering of a thyristor with the voltage generated in a piezoelectric element 9 by target impact or by the action of a spring- loaded plunger 14 which is releasable by a plate 4 after expiry of the maximum flight time. The plate 4 is controlled by clockwork or is dependent upon the rotational speed of the projectile. The delayed firing of the ignition element is alternatively effected by the incorporation in the ignition circuit of an electronic delay or a bypass switch for the thyristor. The ignition element 39 is mounted in a centrifugal rotor 38 and is normally short-circuited by engagement of its contact 40 with the body 1 of the fuze.

Abstract: 1373807 Photo-electric absorption analysis INSINOORITOIMISTO DATEX OY 25 Oct 1971 [4 Nov 1970] 49404/71 Heading G1A In a method of examining a material in which a radiation beam R that has passed through or been back-scattered from the material is divided and at least some of the resulting beams are filtered, one of the filtered beams, e.g. Rb, contains a wavelength which interacts with a component of the material whose concentration is to be measured. As shown two components a and b of the material are determined simultaneously. Filters Fa, Fb remove the wavelengths # a , # b  which interact with the components a and b respectively. Hence the respective outputs from photo-cells D1 and D2 are proportional to the concentrations of b and a respectively in the material. Beam RR, from which both # a  and # b  have been removed, provides a reference output from photo-cell D3. Other filters (F) Fig. 6 (not shown) may be placed in the undivided beam R to exclude unwanted wavelengths. Using infrared radiation from an incandescent lamp source and PbS photo-resistors as detectors, the water content in a paper web may be continuously monitored and the production of the web may be guided and controlled accordingly. Tubes having reflective inner surfaces may be used to conduct radiation from the material to the detectors.

Title: Photographic self-cocking shutter
IPC: G03B9/64
Filed: 1965-11-22
Abstract: 1,080,120. Operation of camera shutters. PRONTOR-WERK ALFRED GAUTHIER G. m. b. H. Nov.22, 1965 [Dec. 4, 1964], No.49472/65. Heading G2A. The blades 2 of a shutter are opened and shut by a reciprocating movement of a driving ring 3. Fig. 1 shows the rest ("closed") position. When the push rod release 20 is pressed, it rotates a shift lever 17 clockwise against spring 19. This pushes a driving pawl 14, to which it is pivoted, to the left, which in turn engages a lug on a lever 7. This is pivoted clockwise against a spring 8, which is accordingly tensioned and acts as the driving spring for the shutter assembly. When the shutter runs down, the lever 7 imparts the required reciprocating movement to ring 3 by means of two associated levers 10, 11. Shift lever 17, at the same time as it pushes pawl 14, also engages and pivots an actuating lever 23 against spring 28. Lever 23 eventually closes a switch 36 in an RC timing circuit, which energizes an electromagnet 30 to attract and hold an armature 25 pivoted at one end of lever 23. Lever 7 has meanwhile performed the first part of its reciprocating action on ring 3, and has brought it to the "shutter open" position of Fig. 2 (not shown). As lever 23 turns anti-clockwise, a stop lever 34 pivoted to it turns with it, and so latches into a recess 3c of ring 3. As long as it remains in this recess, ring 3 cannot complete its running down movement, and the shutter remains open. When, after a predetermined time set by the RC circuit, the electromagnet is de-energized, armature 25 is released, lever 23 is retracted by spring 28, and withdraws lever 34 from recess 3c, so allowing ring 3 to complete its running down and close the shutter.

The ampoules are delivered from a container 1 in single file by a pair of wheels 2 to the nests 4 in the wheel 3 which is inclined to both the horizontal and the vertical and is intermittently rotated. The illumination station comprises a light source 6, a collimator and one or more colour filters 7. While the wheel 3 is stationary the ampoules while illuminated are inspected from behind a screen 8 through a magnifying lens 9. When contamination is observed in an illuminated ampoule the operator marks it by means of a push button and as the marked ampoule reaches the rejection station 10 it is ejected into a receiver 11. Unmarked and hence accepted ampoules are ejected at the collection station into a receiver 12. If it is not certain whether an ampoule is to be accepted or rejected it is provided with a mark denoting repetition as a consequence of which a catch 1) blocks the path of the ampoule into the receiver 12 and the ampoule is carried by the wheel back to the illumination station for re-inspection.
