Title: Improvements in thread tension regulating means for reeling machines and the like
IPC: B65H59/24
Filed: 1953-12-02
Abstract: 746,878. Thread tension regulating means. REYES, J. V. Dec. 2, 1953 [May 8, 1953], No. 33464/53. Class 120 (2). A thread tension regulating- mechanism comprises two pairs of opposed tensioning discs mounted loosely on sleeves fixed to a frame, a pair of axially displaceable spindles extending respectively through the discs of each pair, a helical spring mounted on each spindle between an adjustable abutment such as a nut and one of the discs for biasing said disc towards the other disc of the pair, two rocking levers fulcrumed on pins fixed to the frame respectively, one at the inlet and one at the outlet side of the mechanism, the distal end of each lever having a thread eye and the opposite ends of the levers being crossed and each pivotally connected to one end of a respective one of said spindles, said crossing ends being connected together by a pin-and-slot arrangement and subjected to the action of a spring opposing the action of the disc springs, whereby excessive tension of the thread either in the inlet or outlet thread eyes causes displacement of the levers and partial relaxing of the pressure springs of both tensioning discs. In the embodiment shown, two sets of discs 14 are mounted on sleeves 12 carried by a flange 11  of support frame 10. Inside the sleeves 12 are spindle 15, 15<SP>1</SP> able to slide axially and provided at the top with a screw portion carrying a ring 16 and lock-nut 17, a helical spring 18 being arranged between the ring and the top plate of each pair. The lower ends of the spindles 15, 15<SP>1</SP> are connected respectively to thread guide levers 29 and 24 which are pivoted at 21 and 20 and carry guides 28 and 23 respectively. The two levers are coupled together by a pin 31 on the lever 29 engaging a slot 32 in lever 24. To the lever 24 is attached one end of a spring 38, the other end of which is attached to an arm 37 on nut 46 which can ride up and down a spindle 35 when the latter is turned by means of a button 36, the position being lockable by a fixing screw 40. The thread passes through the guides 23 and 28 and between the friction discs 14 and the arrangement is such that any increase in the tension in the thread will cause the levers 24 and 29 to oscillate, thus bringing about displacement of the spindles 15, 15<SP>1</SP> and a relaxation of the pressure of the plates on the thread, the tension thus being maintained within close limits.

Title: Apparatus for examining the surface of an object using electro magnetic radiation
IPC: G01N21/55
Filed: 1971-07-16
Abstract: 1369214 Investigating the surface of an objec NATIONAL RESEARCH DEVELOPMENT CORP 26 June 1972 [16 July 1971] 33560/71 Heading G1A In a surface investigation apparatus an apertured plate is placed opposite the surface and means are provided for distinguishing radiation reflected from the surface "per se"  from radiation reflected from the plate area surrounding the aperture. The surface may be placed on a vibrating support, or polarized light may be used (whose angle of polarization would be altered by surface irregularities or movement of the surface) both ways changing the radiation reflected from the surface from that of the plate, and by investigating the reflected light (from the surface and the apertured plate) for modulated radiation the modulations can be used to provide information about the surface of the object. In Fig. 1 a laser beam is directed on to the aperture 16 in a plate 18, and the surface 22 is mounted on a longitudinal acoustic wave transducer 24 causing it to vibrate and thereby phase modulating the reflected light relative to the light reflected from the plate 18. The light received by the photo-detector 28 is connected to one input of an electronic phase sensitive detector 30 along with an output from an oscillator 26 which also supplies the acoustic transducer 24, so that the output of the phase sensitive detector 30 is representative of the modulated component of the photo-detector. The phase sensitive detector's output may be used to control the brightness of a cathode ray tube beam while the "X" and "Y" directions of the tube may be controlled by respective sensors 34 and 36 arranged to detect movement of the object 20 in a plane parallel to the aperture plate. The level of illumination of the aperture may be increased, Fig. 3 (not shown) by placing a hemispherical reflector with a hole in it for the passage of radiation, in front of the apertured plate. In Fig. 4 the laser source beam splitter and lens are replaced by a micro-wave frequency oscillator which is connected to the arm 42 of a "magic T" or "hybrid T" guide. Of the two side arms of the hybrid T, are, 44 is closed by a reflector 46 while the other, 48, is closed by a plate 50 containing an aperture 52 of a diameter less than the wavelength of the output signal from the oscillator 40. The output signal from the arm 54 is fed to a receiver 58 and thence to a phase sensitive detector and processed as before.

Title: Improvements relating to methods and apparatus for use in drawing tubes
IPC: B21C5/00
Filed: 1958-10-27
Abstract: 837,386. Drawing; rolling. BREMSHEY, F., and EICKHORN, K. H., [trading as BREMSHEY & CO.]. Oct. 27, 1958 [Oct. 26, 1957], No. 34342/58. Class 83 (4). In a method of forming a tag end on a tube to be drawn, at least one inwardly-directed fold is rolled into the end of the tube, after which the end portion is reduced in diameter by rolling pressure acting substantially at right-angles to the direction of the rolling pressure which produced the fold. The pair of pilger rolls 5 for producing the folds 2 have a central rib 9 which is toothed to prevent slip. The second pair of pilger rolls 11 which reduce the work diameter have a circular pass that decreases continuously through an angular range 15. The tube 1 is passed freely through stationary rolls 11 by a conveyer band until it meets a stop 17 which acts as a feeler and connects the drive for the rolls. In the driving means (not shown) there is interposed a single revolution coupling which ensures that the two pairs of rolls rotate simultaneously and each make only one complete revolution. The rolls 5 first act on the tube and produce the folds 2 while pushing the tube backwards through the rolls 11. The deformed section of the tube is then passed through the rolls 11 and the folds are squeezed together to form the cross-section shown in Fig. 2. When the tube has left the rolls 11 it is ejected sideways in the direction of the arrow C.

Abstract: 800,076. Printing on eggs. COPE, WHELON & CO., Ltd. Nov. 30, 1956 [Dec. 2, 1955], No. 34580/55. Class 100(2) An egg stamper comprises a pivotallymounted arm adapted to receive an egg and arranged to tilt in response to the weight of the egg so as to project the egg against a rubber or similar stamp movable with the arm. The pivoted arm 7 comprises a stout wire frame carrying at one end a rubber stamp 8 and mounted at the other on a cross-member 12 carried by pivots 9 on two parallel channel-section longitudinal members 1. The cross-member 12 carries adjustable weights 15 which serve to keep the arm 7 normally in the horizontal position. A flat cross-member 2 is welded to the upper flanges of the members 1 and is inclined at about 45 degrees to the vertical. The member 2 has at its mid-point a small arcuate cut-out 3 in its lower edge and a slot 4 extending downwards from its upper edge in which is mounted an inking pad 5, facing downwards. On each side of the cut-out 3 are domed rubber buffers 6 facing upwards and the arm 7 is rubber covered at 10; a curved piece of stout, rubber-covered wire 16 is mounted on the members 1 adjacent to the cross-member 2. The stamp 8 is normally held in contact with the inking pad 5 by weights 1'5. When an egg drops, e.g. from an egg grader, on to the stamping machine the buffers 6 and wire 16 orient it so that the least curved surface is presented for stamping and then allow it to fall on to the rubber covered parts 10 of the arm 7 which tilts downwards under the weight of the egg, the cut-out 3 ensuring that the egg does not touch the metal of the cross-member 2. The egg rolls down the arm 7 until it contacts the stamp 8 at 17, Fig. 2, receives an impression and rolls off into a tray below; the arm 7 then reassumes horizontal position and the stamp is re-inked by the pad 5. The machine is intended for use in conjunction with an egg-grader such as that described in Specification 740,426 [Group XVIII], and in that case a series of arms 7 and cross-members 2 and 12 is mounted on the longitudinal members 1 corresponding to the number of weighing pans on the grader.
