Abstract: 1,165,695. Temperature sensitive devices. ELECTRICITY COUNCIL. Oct. 3, 1966 [Oct. 6, 1965], No.42400/65. Heading G1D. A portable temperature sensitive device which may be used to indicate the attainment of a particular temperature by a surface 20, comprises a magnet 2 by means of which the device is attached to the surface 20 and which conducts heat to a disc 11 of wax or other fusible material so that when the melting point of the fusible material is reached, the material melts and a spring (not shown) embedded therein pushes off a cover 8, previously secured to the magnet 2 by the disc 11, to expose a brightly coloured disc 5 surrounding the magnet. The device is primarily for use with pole mounted transformers and is positioned on the oil tank of such transformers. The cover 8 is of thermally insulating material, e.g. expanded polystyrene, and is attached to the disc 5 by a chain which prevents its loss after it has been pushed off the magnet 2. The disc 5 is brightly coloured to render it visible from a distance.

Filed: 1969-08-28
Abstract: 1,235,036. Delivering sheets. INTERNATIONAL STANDARD ELECTRIC CORP. 28 Aug., 1969 [30 Aug., 1968], No. 42816/69. Heading B8R. Documents are delivered in succession down a curved guide channel 6, Figs. 1 and 2, by rollers 11-16, intercepting a light beam to a photo-electric cell 67 to control a valve to deliver jets of air in the direction of arrows 65. Each document passes on to a frame 23 comprising bars 24-28, Figs. 1, 3 and 4, forming a grid having a curved surface which flattens as it extends downwards. The document then passes between blades 35 and a stack 64 supported by an end wall 56 to abut a cushion 61 on a plate 55, while the air from the jets, which was insufficient to blow the document off the grid while held by the rollers 15, 16, now completes the stacking movement. The pressure of the document on the blades 35 pivots the frame 23 to operate a servo-mechanism which moves the stacking means to the right along a surface 59. If a document exceeds a certain length, continued interception of the light beam operates through a delay mechanism a valve to produce air blasts in the direction of the arrow 66 to prevent folding over of the tracking edge. In the case of a document much wider than the frame 23, a further rod 29 of the latter prevents folding over of the edge of the document on the right in Fig. 4. To minimize damage to a document abutting the cushion 61 at an angle, the surface of contact with the cushion is increased by providing the plate 55 with a raised portion 60.

Title: Method of and apparatus for revising workpiece temperature estimates or measurements using workpiece deformation behavior
IPC: B21B1/22
Filed: 1970-09-08
Abstract: 1325883 Rolling mills GENERAL ELECTRIC CO 8 Sept 1970 [7 Oct 1969] 42989/70 Heading B3M A method of revising a measured or estimated value of workpice temperature in a rolling mill comprises using a function of temperature-roll force characteristics for the mill to predict the expected roll force from the temperature value, measuring the actual roll force and using the discrepancy in roll force values to deduce the temperature error. This revised temperature is used to modify the established temperature value and also to control a screwdown control. The workpiece is fed from a furnace 10 to a roughing mill 16 for several passes and to a finishing mill 22. The functions are initially established experimentally for different working conditions. The measured or estimated temperature Ti is used to extract an expected roll force Fi. The actual roll force Fa is measured by a load cell 32 and used to deduce the actual temperature Ta. The revised temperature Tr is the average of Ti and Ta and is fed to a screwdown control system 38. The revised temperature is also used as the established temperature for the next pass. The workpiece temperature may not be critical in the early roughing passes and the automatic control may be used only on the last roughing pass. Alternatively the average difference between Ti and Ta may be used to determine the new established temperature for the next pass. A further method uses the function of roll force ratio Fa/Fi against temperature to deduce the actual temperature, This function is linear over a small range so that the temperature error can be calculated using the function gradient and the roll force error. The values of Fa/Fi for successive passes are stored and averaged and compared with a force value ratio of 1À0 to establish the roll force error. The signals between the control parts may be analog or digital.

Abstract: 899,313. Spinning yarns. COURTAULDS Ltd. Dec. 20, 1960 [Dec. 21, 1959], No. 43278/59. Class 120(3) Fancy yarn is produced by associating together two or more continuous, dry-spun filament bundles having a similarly varying denier so that the denier variations coincide or are off-set by a constant distance (the bundles remaining separable) passing one or more of the bundles at a uniform speed into a tur- 'bulent fluid zone while one or more of the bundles is fed to the same zone at rapidlyvaried random intervals to provide random lengths of overfed filaments which form neps in the turbulent zone, and intertwisting all the bundles leaving the zone. The entry and departure speeds of the bundles to and from the zone may be the same so that the collected yarn is free from surface loops. The filaments may be of cellulose acetate or triacetate or vinyl polymers such as the copolymer of acrylonitrile and vinylidene chloride, spun-dyed and/or of different colours. As shown, bundles 1, 2, are withdrawn from spinning cells 3, 4, and pass via eyes 5 and 6 and a slubbing guide 7 carried on a shaft 9 which is oscillated by randomly operated mechanism (not shown) to produce the variations in denier, thence to a godet 8 on which the bundles are assembled with the variations coincident. Bundle 1 is withdrawn at constant speed via eyes 10 (mounted on a grooved rod 20) and 12, thence to a bulking air jet 13: simultaneously therewith, bundle 12 is withdrawn via guide 10 and passes to jet 13 in advance of which it is continuously raised and then suddenly released by a variable speed cam 15 so that the filament length accumulated by such cam action is taken-up by the jet to form neps which appear in the yarn as collected on a bobbin 19.

Abstract: 1371493 Character recognition systems MASSON SCOT THRISSELL ENG Ltd 4 Oct 1971 [10 Sept 1970 9 Oct 1970] 43447/70 and 48237/70 Heading G4R Characters specially shaped to facilitate automatic character recognition are formed of straight line portions, e.g. of selected ones of 9 lines as at 20, Fig. 1. Each of the 9 possible lines in a character is sampled at a point between its ends, e.g. at 21-29, Fig. 3, providing a 9-bit signal which identifies the character. As applied to the recognition of postal code written on printed grids 11-16 on an envelope, the envelope is passed before a cathode-ray tube. When a photodetector senses the leading edge 60 of the envelope a flash lamp is fired so that a stationary image of the postal code, together with control marks 30, 41, 42, is impressed on the tube. Scan control circuiting causes the C.R.T. beam to perform a raster scan 40, Fig. 3, to detect the leading control marks 41, 42. When the start of the control marks 30, 31 associated with the first character grid 11 is detected the scan changes to pass through each of the 9 lines of the grid. The scan path may be as in Fig. 3, or as in Fig. 4 or 5 (not shown). The C.R.T. output passes to a gate which samples the signals corresponding to points 21-29. The samples pass to a recognition unit which generates a binary coded decimal respresentation of the character recognized. After a character is scanned the scan reverts to raster form to search for the control marks of the next character. The recognition unit is wired to detect not only correctly formed characters but also characters which are incorrectly formed or off-centre, as described with reference to Fig. 8 (not shown). To reduce the sensitivity of the system to unwanted marks on the envelope, or to gaps in the character lines, the C.R.T. beam is wobbled to provide a broader scan, Fig. 9 (not shown).
