Abstract: 1356675 Joining superimposed continuous webs MOLNLYCKE AB 12 Aug 1971 [21 Aug 1970] 37931/71 Headings B5N and B5K Superimposed continuous running webs or parts of a web folded in the longitudinal direction are joined transversely by inserting between the running webs or parts of-the folded web a continuous thermoplastic web at a speed lower than that of the webs or parts of the folded web, and subjecting the webs or parts of the folded web to local heat and pressure across the webs or parts of the folded web in a transverse direction. The additional thermoplastic web may be fed in between the webs or web parts to be united at one side of these webs or web parts and at an angle to the side edge, all the webs being subsequently moved in the same direction. In the drawing webs 1 and 2 to be joined, which may be separate webs or two parts of one web folded longitudinally, are fed forward by pairs of feed rollers 3, 4 and 5, 6, thermoplastic web 9 being fed by feed rollers 7, 8 at a lower rate than rollers 3, 4 and 5, 6 over web folder or sword 10 arranged between webs 1 and 2 so that the part of thermoplastic web 9 lying behind folder or sword 10 is in contact with webs 1 and 2 and is inclined to accompanying them to heat and pressure applying means comprising rollers 11 and 12 provided with longitudinally extending heatable compressing and/or stamping elements 13 and 14. The speed of rollers 7, 8 is co-ordinated with that of rollers 11, 12 so that for each rotation of rollers 11, 12 the rollers 7, 8 feed only that amount of web 9 which corresponds to the width A of the joint, and because of the lower feeding speed of rollers 7, 8 compared with rollers 11, 12, web 9 is secured at the moment of union and is then torn off along the line formed by the compressing and/or stamping elements 13, 14. Rollers 11, 12 may be provided with knives to perforate webs 1 and 2 which have been transversely sealed in the centre of the seams or cutting rollers may be placed downstream in the direction of movement of the webs which are synchronous with rollers 11 and 12.

Title: Improvements in or relating to acousto-optic devices
Inventor: DIXON RICHARD WAYNE
IPC: G02F1/33
Filed: 1969-07-30
Abstract: 1,262,190. Modulating light. WESTERN ELECTRIC CO. Inc. 30 July, 1969 [31 July, 1968], No. 38217/69. Heading H4F. [Also in Division H1] An acoustic-optic device comprises a single- or polycrystalline element of α-H10 3  or α-D10 3  or a mixture of the two, provided with means for generating elastic waves in the element so that light of wavelength 3,000-23,000 Š i.e. where the crystal is transparent, undergoes Bragg or Raman-Nath diffraction. The means for generating elastic waves may constitute an elastic wave transmission line, or a piezo-electric, electrostrictive, or magnetostrictive transducer, or merely a pair of electrodes, since α-H10 3  itself is piezo-electric. The embodiment of Fig. 2, which uses two devices described in more detail with respect to Fig. 1 (not shown), directs a light beam 21 to appropriate X and Y positions on a display screen and/or information storage plane 20 e.g. for scanning the screen as a raster or for photographicor holographicinformation storage. Stored information may subsequently be projected into an array of light detectors (not shown). By suitably varying the frequency and amplitude of the waves generated by the acoustic transducers 16, 18, which are of lithium niobate in this instance, the device may be operated as a general information processing device using an optical (communications) link. Thus by following the (swept) frequency of a chirped radar signal, pulse compression is achieved. Correlation, filtering, spectrum analysis may also be carried out. In a light modulator, Fig. 5 (not shown), wherein a detector senses the undiffracted portion of the light beam, the transducer is curved to focus the elastic waves, thus reducing the acoustic energy required. Fig. 4 shows a YAG-neodymium laser 36 incorporating an element 35 of α-H10 3 . A standing wave is produced in element 35 by a transducer 39 such that the periodicity of the diffraction mode-locks the laser. A further transducer 40 deflects and samples the laser light using Bragg diffraction. Mode locking itself may be accomplished with either form of diffraction, although Raman- Nath diffraction is more customary. The crystal may contain some impurities e.g. to absorb unwanted optical radiation, or to provide the active laser medium, for instance, up to 1% by weight of chromium, neodymium and iron.

Abstract: 1,158,388. Indicating and recording apparatus. KINGMANN-WHITE Inc. Aug. 22, 1967 [Sept. 16, 1966], No.38533/67. Heading G1J. Apparatus is provided for simultaneously zeroizing two different indicating devices both of which are actuated by the same signal source through a coupling device including zero adjusting means. A signal source, for instance a differential pressure flowmeter rotates shaft 30 by means of lever 26 and link 22. Coaxially mounted on shaft 30 is a sleeve 40 which fixedly carries at one end a pen recording arm 46 for recording the value of the variable on chart 50. This pen and chart constitutes one of the two indicating means. At the other end of the sleeve 40 a lever 78 is fixedly mounted. This lever 78 actuates by means of link 82, an integrator, which constitutes the second indicating device. To zeroize both recorder and integrator simultaneously, the sleeve 40 is rotated relative to shaft 30 by means of an adjusting means 56, which includes a screw passing freely through a hole in an ear 58 of a lever 54 fixedly mounted on a shaft 30 and threaded into an ear 60 on pen recording arm 46. A compression spring 76 around the adjusting screw maintains ear 58 against the head of the adjusting screw. When the pen recording arm 46 is shifted relative to shaft 30 to bring the pen to a zero position, the integrator is shifted a like amount to bring it to zero position. A modification is also described.

Abstract: 1,244,698. Echo sounders; pulse circuits. FRIED. KRUPP G.m.b.H. 1 Aug., 1969 [3 Aug., 1968], No. 38636/69. Addition to 1,204,939. Headings H3T and H4D. In a development of the echo-sounder in the parent Specification (Division H4) an additional echo-duration selector 24 is provided in which the output pulse of the duration-sensitive Schmitt trigger 9 is compared with a locallygenerated reference pulse of predetermined maximum duration. Monostable 28 is triggered by the Schmitt 9 output c to give the reference pulse v, and logic circuits 27 give an output signal k only if c is of greater duration than v. Only if signal k is present will gate 25 supply a stop signal to the depth-indicating counter 7. Alternatively, duration-selector 24 may be arranged to give a signal k only if c is of shorter duration than v. A further duration-selector (24a) and counter (7<SP>1</SP>) may be added (Fig. 4, not shown) for indicating those echoes whose duration lies between two selected limits. Circuit details.-The duration of the unstable state of monostable 28 (i.e. the duration of reference pulse v) is made equal to the duration of the triggering pulse c, so long as pulse c does not exceed the predetermined maximum duration of pulse v (which is fixed by the time constant of R and C) by providing diode 29 across the monostable. This ensures that a brief interference pulse triggering the monostable will not prevent a longer useful input pulse from triggering the monostable shortly afterwards.

Abstract: 1,193,513. Collating sheets. RANK XEROX Ltd. 23 Aug., 1967 [25 Aug., 1966], No. 38855/67. Heading B8R. A machine 200 for collating sheet material comprises a series of units 100 arranged in side-by-side operative relationship, each unit including a series of superposed sheet-collecting trays, each tray having at its entrance a sheetdiverting mechanism which, on actuation by mechanism controlled by a programmed control device M-2, either feeds the oncoming sheet into the tray or diverts it for subsequent delivery to a tray lower down. Photo-electric cells are used so that the diverting mechanisms are actuated by moving sheets. Surplus sheets, i.e. sheets surplus to the number of collecting trays in the machine, are diverted to a collecting bin which is arranged in the sheet flow path before the trays. Any sheet jam occurring in the machine causes an automatic mechanism to divert any sheets fed subsequent to the jam to the collecting bin. The top of each collator unit is hinged to provide ready access to the sheet flow path of the machine.

Title: Control circuits particularly for highway crossing control systems

Filed: 1973-08-20
Abstract: 1447511 Level crossing control GENERAL SIGNAL CORP 20 Aug 1973 [21 Aug 1972] 39293/73 Heading B7N In a level crossing arrangement two track circuits 12, 13 overlap at the crossing 11 and the road traffic crossing signal 19 is cleared when a train has left the crossing and the overlap section. The crossing signal is held clear in the absence of a train by pick-up of a relay 35 which is energized from an oscillator 24, supplying a square wave and D.C. signal, via gates 45-48 which are enabled respectively by the east track circuit receiver output RE, the west track circuit receiver output WE and by the absence of outputs on terminals SE and SW of hold circuits 26, 27 associated respectively with the east and west circuits. On entry of a train into the west circuit 12 the receiver output RW drops away thus closing gate 46 so that with cut-off of the oscillator signal relay 35 de-energizes to activate the crossing signal 19, and enabling gate 22 to supply the oscillator output to a hold OR gate 25 and to a gate 56 in a cross inhibit circuit 23. The gate 56, enabled by the absence of an output SE from hold circuit 26 applies the signal to OR gate 64 in hold circuit 27 which supplies an output SW which inhibits gate 57 in the east circuit part of the cross inhibit circuit, closes gate 48 and also enables gate 66 so that the output of hold OR gate 25 is supplied after immersion as a second input to OR gate 64 so that the hold circuit output SW is maintained until the train has cleared both track circuits. When the train enters track circuit 13 the output RE of the east track circuit receiver drops away so that gate 21 now supplies a second input to hold OR circuit 25 and when it leaves track circuit 12 the output RW of the west track circuit is restored thereby enabling gate 29 so that the output from gate 66 in hold circuit 27 is applied to buffer 32 to replace the signal still cut-off at gates 45 and 48 by signals RE and SW. The buffer supplies a signal to pick-up relay 35 and clear the crossing signal.
