Title: Label packs and their production
IPC: B65C9/10
Filed: 1974-11-15
Abstract: 1477000 Packaging labels H KRONSEDER 15 Nov 1974 [24 Nov 1973 10 July 1974] 49601/74 Heading B8C In a method of packing labels in a stack to form a stable unit, as defined below, for transport and for insertion into a magazine or like receiving device of a labelling machine, a series of at least two thousand identical individual labels is assembled together as a stack with the individual labels in close face contact and their edges in alignment and the stack is advanced past supply locations for two adhesive-bearing strips at opposite sides of the path of movement of the stack, the strips being applied against the face of the leading member of the stack, and, while the stack is advanced and being held under compression in its direction of advance, the strips being applied against their respective sides of the stack to extend longitudinally thereof, the strips then being applied against the face of the final member of the stack, the adherence of the adhesive to the labels being less than the cohesion of the adhesive and the adherence of the adhesive to the strip carrier, or backing material, being greater than its adherence to the labels. The term stable unit means that the stack does not fall apart when it is subjected to normal forces of being gripped manually or, mechanically or being moved about, and the labels do not lose their alignment relative to one another. The label pack, Fig. 1, comprises, e.g. 7000 identical labels 2 which are bound together by two adhesive strips 3, 3 which exert a slight pressure on the ends of the stack. The pack is completely enclosed in a protective wrapping of shrinkable sheet material, e.g. flexible tubing welded at both ends, the wrapping, and the binding strips, being removed before the pack is used. Two tapes 13, 13, Fig. 2, extend tightly over the upper and lower longitudinal sides of a stack of about 6000 of identical shoulder labels 12 and adhere to the edges of the labels, and to the end labels where they are connected to each other, at least one connection being extended to form a tab 14 and the labels being longitudinally compressed. As shown in Fig. 3, two pairs of strips 17, 17 and 18, 18 are in orthogonal relationship each pair being joined at each end to provide offset tabs 14, 14. In an apparatus for taping stacks of labels a pair of adhesive tapes, drawn from spring-loaded reels 30, 30 on opposite sides of a guide channel 32 and joined across the front of a stack being bound, is pressed along the sides of the stack by rollers 42 and/or pressure pads 44, as the stack advances through the channel 32. The tapes are secured together at the trailing end of the stack by a pair of slides 36, 38 which tension the tapes as they are moved together and which sever and reform the tapes ready for the next stack when it is released by pivotally-mounted flaps 40, 40. Cross-taping, as shown in Fig. 3, can be obtained by passing a stack of labels through the channel 32 twice.

Abstract: 1,210,658. Printing-apparatus. DENNISON MFG. CO. Ltd. 1 Nov., 1967 [1 Nov., 1966], No. 49656/67. Heading B6C.  Apparatus for transferring indicia from a web 80 carrying two rows of indicia on to an article such as a bottle having a longitudinal axis and two peripheral portions (s), (s<SP>1</SP>), Fig. 3 (not shown), of differing radial extent comprises means 3-12 for feeding the web past a transfer station at which is located an applicator device for transferring the indicia to the portions of the article, and a knife 17 in advance of the said station for splitting the web into two ribbons. The applicator device is formed by two rollers (23), (24), Fig. 3 (not shown), of differing diameter each designed to transfer indicia from one row on to one of the peripheral portions under heat and pressure. Articles are presented in turn to the station by a rotatable turret 25. Guide means downstream of the station guide the ribbons in edge-to-edge relationship to a take-up reel 2. The roller (23) is mounted in a support which may be pivoted to adjust the angle of the axis of the roller (23) with respect to that of the roller (24). The roller (23) may also be adjusted vertically. The applicator is movable from an operative position in which it presses the ribbons against the article to a retracted position in which the ribbons extend across the station in straight paths between guide means. The web or ribbons are heated by a heater 14, a heated shoe-shaped block (31), Figs. 2 and 3 (not shown), and by the rollers (23), (24). An oscillated bar 59 controls the web feed and ensures that there is no slippage between the article and the web &c.

Title: Reactive dyes containing ethylene imide groups and their use in dyeing
IPC: C09B62/62
Filed: 1963-12-17
Abstract: The invention comprises reactive organic dyes containing in the molecule at least one radical of formula <FORM:1037166/C4-C5/1> which may be further substituted on the carbon atoms of the ethylene-imino ring.  The dyes are prepared by treating a dye or a dye intermediate containing 1 to 4 b -sulphatoethylaminomethyl groups with a base such as sodium or potassium hydroxide to effect cyclization and when necessary forming a dye from the intermediate by the azo coupling reaction or by condensation.  The b -sulphatoethylaminomethyl groups are introduced into the dye or intermediate by chloromethylation, reaction of the chloromethyl derivative with ethanolamine and treating the b -hydroxyethylaminomethyl compound with a sulphating agent which may also effect sulphonation of the nucleus.  The dyes may be applied to fibres containing replaceable hydrogen, particularly cellulose, from an aqueous solution at pH 4-14 and preferably in the presence of 0.5-5.0% zinc borofluoride.  Ring splitting and addition reactions are stated to occur.  The preparation of monoazo, anthraquinone and phthalocyanine dyes is described.ALSO:2,6 - Bis - (b  - hydroxyethylaminoethyl) - p - toluidine is prepared by condensing 3,5-bis-chloromethyl-4-nitrotoluene with monoethanolamine and reducing the resultant nitro compound by catalytic hydrogenation.

Title: Head positioning servo systems
IPC: G05B19/23
Filed: 1972-11-01
Abstract: 1368164 Head positioning system POTTER INSTRUMENT CO Inc 1 Nov 1972 [27 Dec 1971] 50348/72 Heading G4H A servo system for moving a head across a specified number of information tracks has means to prevent overheating of the drive motor. A representation of the motor temperature in the form of the motor power time product is generated and the motor drive is cut off when the product exceeds a predetermined value As described, the binary coded number of tracks to be moved is entered into counter 17. A plurality of heads 13 co-operating with discs 14 are driven by linear motor 10. The head velocity is sensed at 22 and each track crossed produces a pulse in transducer 16 which pulses count down counter 17. The count is this counter is converted to an analogue signal in converter 20 and is applied to one input of differential amplifier 21, the other input being the head velocity signal from 22. The drive voltage at the amplifier output is fed via gate 30 to differential amplifier 23 and the difference between it and a current proportional voltage from resistor 22 controls the motor 10. Multiplier 28 has as inputs the current proportional voltage and the motor voltage comprising the difference between the applied voltage via R 1  and the back EMF (proportional to head velocity) via R2. The resulting power output is compared at 38 with a reference. If the power is below the reference, gates 52 and 42 are enabled via inverters 54 and 55 respectively. A reference voltage 56 is applied via resistor 58 to two one shot multivibrators 37, 36 connected as a frequency proportional to voltage oscillator. The oscillator pulses are fed via gate 42 to the down output of counter 32. If the power exceeds the reference, gates 46 and 41 are enabled and voltage 56 is passed to the oscillator via FET 62 acting as a variable resistor. The FET gate is driven by amplifier 64 hovering as inputs the "power" voltage from multiplier 28 and the integrated pulse train from 68. The resulting pulse frequency is proportional to power and is applied to the up input of counter 32. Decode circuit 72 enables gate 74 when the counter reading is below a predetermined value and passes a start signal from bi-stable 76 to set bi-stable 75 and enable gate 30 supplying power to the motor. A rise in the counter reading above this value indicates that the motor is near overheating, resets bi-stable 75 via line 81 and cuts the drive power. Capacitor 82 forms an RC network with the converter 20 and is discharged by current sources 86 or 88 when 84 detects "one" or "no" "tracks to go" respectively. Converter 20 is constructed so that its output is constant for an input of 32 or more.

Title: Method of producing a strapped bundle of newspapers
IPC: B65H31/26
Filed: 1974-11-21
Abstract: 1459536 Producing strapped bundles of newspapers; boxes H A BAKKEREN 21 Nov 1974 [11 Dec 1973] 50522/74 Headings B8C and B8P [Also in Division E2] In a method of producing a strapped bundle of newspapers a stack of newspapers is formed, by a stacking device, in a holder which supports the sides of the stack to maintain the stack intact, and the stack in the holder is conveyed, by a conveyer, to a strapping device, and is then strapped by the strapping device. The invention is particularly applicable to stacking devices directly adjoining high-output printing presses which produce stacks of a predetermined number of newspapers. As shown in Figs. 1, 2, a frame comprises four individual parts 1-4 each consisting of side walls b, c which are hinged to a bottom wall c, and which are assembled together to form a frame with seams 5, 6 and vertical seams 9 at the corners. In an alternative arrangement each individual part 1-4 is formed as a rigid unit. At the seams 5, 6 the co-operating edges 10, 11 of the individual parts 1-4, Figs. 5, 6, are respectively of "V" and "W" shaped cross-section and have recessed therein respective magnets 12, 13, the seams 5, 6 forming outwardly open V-shaped grooves into which strapping material can penetrate which material, upon tensioning, presses the individual parts 1-4 apart. Each bottom wall c has a recess 14, which, with associated recesses 14, forms an aperture for receiving the closing mechanism of the strapping machine. In a modification, Figs. 7, 8, the individual frame parts 1-4 are spaced by gaps such as 16, 17 magnets 15 being located at the frame corners and the parts 1-4 being detachably secured together by bolts 19 and associated pawls 29. Each bolt 19 has an operating pin 28, is slidably accommodated in a recess 20 in a side wall b, and is loaded by a spring 25 which urges a hook end 26 of the bolt 19 entirely within a corresponding recess 27. In its extended locking position the hook end 26 of the bolt cooperates with the pawl 29 on an operating rod 30 which is mounted for vertical sliding movement in the adjacent side wall and which is urged upwardly by a spring 31. As the bolt 19 is moved into its latching position a gear rack 32 on its upper edge co-operates with a gear wheel 33 which meshes with a rod 34 slidably accommodated within a recess 35 in the associated side wall to project from the edge of the latter and from a stop for the opposing wall b and correctly gauge the gap between the frame parts 1-4. The holder may consist of a comparatively rigid envelope 37, Fig. 3, made of synthetic material, and which is not removable at the strapping station.

Abstract: 1,036,010. Controlling aircraft. MESSERSCHMITT A.G. Dec. 20, 1963 [Dec. 20, 1962], No. 50559/63. Heading B7G. Apparatus for providing air streams into the wings of an aircraft includes at least two main air ducts disposed in the direction of the longitudinal axis of the aircraft, a transverse duct connecting the main air ducts and connecting with air outlet means locatad in the aircraft wings on either side of the aircraft for discharging air therefrom, discharge ducts connected to each main air duct for discharging air therefrom, control valve means in each said main duct, closure valve means for each said discharge duct, all said valve means being so positioned and adapted to be controlled by air flowing forwardly through said main air duets that if no air flows in any one of said main air ducts such duct is closed and thereby causes simultaneous closing of the discharge duct of the other main duct or duets, air flowing in the other main duct or ducts being directed wholly to the transverse duct to maintain equality of air flow to the outlet means in the wings on either side of the aircraft. A pair of ducts 2, 3 (Fig. 1, not shown), are arranged longitudinally in the fuselage to connect with a transverse duct 12 in the wing 5 and further ducts 10, 10a which terminate in propulsion nozzles 4. Double-leaf flap valves 7, 9, spring loaded to the open position (Fig. 4, not shown) are mounted in ducts 2, 3 respectively and coupled by links 70, 90 with single-leaf flap valves in ducts 10, 10a. The duct 12 extends to blowing slots at the trailing edge 51 of the wing positioned adjacent the upper surfaces of flaps 52. If, in operation, the jet propulsion engine or compressor supplying compressed air to either of the ducts 2, 3 the appropriate valve, in the absence of air pressure, will open from the position shown in Fig. 4 for valve 9 to that shown for valve 7 with automatic operation of the valve in the appropriate duct 10, 10a to close that duct. By this means no air will flow to the nozzles 4 and all the air from the operative duct 2 or 3 will flow uniformly through both sides of the duct 12 to maintain balanced lateral trim.

Abstract: 1484594 Lasers; semi-conductor junction devices WESTERN ELECTRIC CO Inc 22 Nov 1974 [23 Nov 1973] 50700/74 Headings H1C and H1K [Also in Division C4] A semi-conductor junction laser comprises a semi-conductor body including first and second heterojunctions 15, 19 defining an optical waveguide, and a third heterojunction 17 dividing the waveguide portion into two contiguous regions one of which-16-exhibits loss and the other-18-exhibits gain under lasing conditions, at least one of the heterojunctions being a P-N junction. Under lasing conditions the majority carrier concentration in the lossy region 16 is equal to or greater than the electron concentration in the gain region 18. The gain region is thicker than the lossy region and its thickness dg satisfies the inequality: where #n is the refractive index discontinuity at the third heterojunction, # is the full space wavelength of the laser radiation and ng is the refractive index of the gain region. In the example of Fig. 1 the various regions have the composition shown. Layer 22 may be dispensed with, depending on the difficulty of forming an electrical contact directly on layer 20. The structure is cleaved or polished optically flat along parallel surfaces 28, 30 to provide a resonator. An antireflection coating may be formed on surface 28 in order to produce an output beam through that surface. A stripe contact arrangement 40, formed, e.g. by proton bombardment, may be utilized to restrict the laser beam to a central zone 38 of the region 18. AlGaAs may be replaced by other Group III(a) and/or Group V(a) elements to form mixed crystals, e.g. AlGaAsP. To change the relative locations of the three heterojunctions and the relative locations within the three of the gain and loss regions the relative concentrations of the Ga, Al and As components within GaAlAs are altered, Figs. 2-4 (not shown).

Title: Method and apparatus for ejecting containers from a conveyor
IPC: G01N21/90
Filed: 1969-10-20
Abstract: 1,269,686. Conveying and transferring containers. BARRY-WEHMILLER CO. 20 Oct., 1969 [28 Feb., 1969], No. 51439/69. Heading B8A. Apparatus for rejecting undesired containers C from a flow stream 13 of containers advanced along a predetermined path, comprises an endless conveyer 21 having a first linear path 21A coincident with spaced fixed container support means 16, 17, associated respectively with spaced sections of the flow stream 13 and a second linear path 21B at one side of the first path, container support means 33 moved by the endless conveyer 21 through each of the linear paths and selectively movable between a normal container support position (right hand side of Fig. 3) and a folded position (as shown sectioned in Fig. 3) out of container support position while in the first linear path 21A, and control means 42 in the second path operable to predetermine the movement of each of the support means into one of the positions (normal or folded). Containers pass successive inspection devices 83, 80 (Fig. 9), while travelling on a leading section 15 of the flow stream 13. Signals from a clock 86 pulsed by the output from a photo cell 88 obturated by the passing containers are combined with signals from the devices 80, 83. This causes the operation of a reject firing circuit 82 at a predetermined instant in respect of containers which have characteristics which activate the devices 80, 83. The firing of the circuit 82 operates a motor 55 (Fig. 4), of a switching mechanism 42 to trip a guide finger 58 from the position shown in full times to the broken-line position in Fig. 4. This has the effect of guiding cam followers 35 (each carried by an extension of a respective container support flap 33) from a normal path adjacent a guide rail 41A into a guide slot 49 leading to a guide rail 36. Thus support flaps, the respective cam followers 35 of which are deflected on to the guide rail 36, are folded down into a position in which they allow a container C to drop down (right hand side of Fig. 3) into engagement with guide rails 68. Otherwise the containers remain supported by respective flaps 33 at the level of guide rails 16 until they reach guide rails 17 at the downstream end of the conveyer 21. The conveyer 21 has guide pockets 24 for engaging and conveying the deflected containers along the rails 68 to an inspection table 71 (Fig. 1). The timing is such that a container which activates the inspection devices 80, 83, arrives at a station X (Fig. 9) just as the respective deflected flap 33 arrives at position 100 (Fig. 9) from the switching mechanism 42. The follower 35 of a deflected flap 33 is returned to the rail 41A via a gap between an end 36A of the rail 36, and the begining of a rail 40 (Fig. 2) which slopes down wardly to merge into the rail 41A in the vicinity of the switching mechanism 42.
