Title: Recording instrument strip chart mechanism
IPC: G01D15/28
Filed: 1953-09-02
Abstract: 736,654. Recording-apparatus. FOXBORO CO. Sept. 2, 1953 [Sept. 9, 1952], No. 24292/53. Class 106 (4). [Also in Group IX] Apparatus for recording the value of a variable on a chart driven at constant speed comprises a trough 45 frictionally engaging the chart supply roll as it rests therein with a drive roll 67 positively engaging the chart to draw it from the supply roll, a pair of roller shafts 62, 66 forming a trough structure for supporting the re-roll spool in frictional drive relation therewith and a branching driven train, with one branch providing a positive driving connection between a driving element and the chart drive roll and a second branch providing a positive driving connection between the driving element and at least one of the roller shafts. As shown, the invention is applied to recording-apparatus in an open-fronted case 11, Fig. III, with a pivoted transparent plastic cover 12 with snap closure means 13, 14. Troughs for receiving strip chart supply, drive and take-up rolls 40, 67, 30, Fig. IX, are formed in part by curved surfaces 45, 71, 72 of a cross-bar body 42 supported transversely by end plates 43, 44 pivoted about the same axis as a gear-wheel 64, Figs. VII, IV common to two branches of a gear train 58, 61, 63, 64 driven through a spring clutch 50 by a motor 47, one branch 64, 68, 69, 70.being mounted on the end plate 44 and driving the roll 67 whose pins 21 engage holes in the chart to draw it from the supply roll 40 lying freely in the trough formed by the surface 45 and inward projections 46 of the plates 43, 44, Figs. VII and I X. The other branch 64, 65 drives a roller 66 which together with a roller 62, driven with the gear-wheels 61, 63, frictionally drives a take-up roll 30 whose ends 31, 32 lie freely on the rollers 62, 66. The unit 42, 43, 44 is held in normal operative position by springs 78 biasing down a pivoted transverse plate 22 carrying a transverse pin 74 for engagement with slots 75 in arcuate guide edges 73 of the end plates 43, 44. For replacing the rolls or inspecting the mechanism behind the chart the unit may be tilted forward, the gear-wheel 68 rolling round the gear-wheel 64, by lifting a projection 24 of the plate 22 to free the pin 74 from the slots 75 and by manipulating the unit through a knurled grip 80 on the plate 44, movement being limited by projections 79 from the guides 73 engaging the pin 74. Lifting the projection 24 also moves the pen 16 free from the chart and raises a hood 23 on the plate 22 which normally presses the chart about the pins 21 of the drive roll 67. When the unit is tilted forward the chart may be pulled out, the spring clutch 50 allowing reverse movement, and cut by means of a pivoted cutter 36 pulled out into operative position. The clutch also allows zero adjustment between chart and pen.

Title: Improvements in and relating to temperature indicating devices for electrical apparatus
IPC: G01K5/38
Filed: 1930-08-14
Abstract: 353,281. Thermometers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Isaac, A. C. T. ; Ribbesdale, Bilton Road, Rugby.) Aug. 14, 1930, No. 24385. Convention date, Aug. 16, 1929. [Class 97 i (iii).] To indicate load conditions in an electrical apparatus, such as a transformer, immersed in an insulating liquid such as oil, the indication from a temperature responsive means connected with the oil is combined with that of a similar means connected with the water used for cooling the oil. In the example, a bulb 18 in the oil 11 communicates with a Bourdon tube 14 and one 19 in the entering cooling water communicates with a Bourdon tube 15. Pointers 20, 22 are thus separately operated and direct readings may be obtained from each on concentric scales 21, 23. Pointer 20 also bears a moving scale 24 and the reading of pointer 22 on this scale gives an indication of the load conditions in the transformer &c.10.
Patent GB-940427-A (GB)
Title: Sheet take-off arrangement for machines producing envelopes, bags or the like
IPC: B65H1/18
Filed: 1961-07-06
Abstract: 940,427. Feeding sheets. R. WINKLER, and K. DUNNEBIER. July 6, 1961 [Feb. 1, 1961], No. 24422/61. Addition to 858,157. Heading B6B. The apparatus for replenishing a working pile of sheets, which are withdrawn sequentially from the bottom of the pile and fed to a machine for making envelopes, as claimed in the parent Specification, is modified by the provision of a supply pile of sheets 1 which is raised automatically by a lifting means to keep the top sheet at a constant level, oscillating feeler fingers 26 which control the lifting means, an oscillating presser tongue 22 which holds down the sheet below the one being separated, and sheetseparator means which comprises a sucker 16 and rotatable sheet-withdrawing segments 4. Sheet separators and forwarders.-There are two segments 4, secured to a constantly-driven shaft 3, recessed at 6 to provide lips 5, and they co-operate with constantly-rotating resilient rollers 9. The space below the rollers 9 and the curved portion 11 of a plate 10 is connected to a source of suction, and holes 12 are provided in the plate. The sucker 16 is carried by a tube 15 to a hollow oscillating shaft 13 connected to a source of suction. The presser-tongue 22 is secured to an oscillating shaft 20. In operation, the sucker 16 pulls the top sheet 1 from beneath the tongue 22 and raises it to the position 1<SP>11</SP> over the lips 5 of the rotating segments 4, the body of the sheet being sucked temporarily about the plate 10. The sheet is then gripped by the segments 4 and rollers 9 and removed from the pile. Pile tables.-The pile-sensing fingers 26 are secured to a shaft 24 rocked by an arm 27 and a reciprocating link 29. The link 29 is slotted at 30 to fit over the drive shaft 3, and has a roller 32 thereon engaging a cam 35 secured to the shaft 3, and a further roller 34 at the end. A return spring acting on the link 29 causes the fingers 26 to contact the top of the pile of sheets on the table 2, and the height of the pile thus governs the movement of the roller 34 on the link 29. The roller 34 is associated with an electric, electromagnetic, or mechanical switch which controls a driving pawl of known lifting means which is used for raising the table 2.

Filed: 1928-08-25
Abstract: 322,208. Smith, W. S., Garnett, H. J., Dean, J. N., Channon, H. C., Gardner, W, and Wilson, H. F. Aug. 25, 1928. Divided on 307,390. Drawings to Specification. Compositions containing indiarubber and bitumen; vulcanizing.-A composition capable of being extruded at 70‹-120‹ C., particularly suitable for the insulation of submarine cables consists of an intimate admixture of 30-60 per cent of rubber and a high melting point bitumen of low ash and free carbon content. The bitumen should have a melting point above 100‹C., for example, gilsonite, glance pitch, manjak, grahamite. Other substances may be added; when these comprise guttapercha, balata &c., the rubber content may be reduced to 20 per cent or less. The rubber is mixed with the melted bitumen, the temperature being kept below that which would harm the rubber. Up to 10 per cent of a flux such as ceresin, candelilla or other wax may be added, to reduce the melting point, or the bitumen may be finely powdered, and mixing effected at a temperature below its melting point. When gutta percha or balata are added they are preferably purified as described in Specification 307,390, and may form 50-75 per cent of the composition. Hardeners as benzidine, softeners as stearic acid, and antioxidants as tannic acid may also be added. The composition may be vulcanized, preferably by heating to a temperature below the melting point of the bitumen, partially to vulcanize the rubber, and subsequently to a higher temperature to melt the bitumen and to complete the vulcanization. When the composition contains more than 40 per cent of rubber, it is desirable to extrude round the core before the second heating stage. The rubber may be previously treated as in Specification 320,370.

Title: Improvements in or relating to drying peat and other materials
IPC: F26B3/00
Filed: 1932-09-02
Abstract: 406,062. Drying materials such as peat. GRAM, T., and TECHNO-CHEMICAL LABORATORIES, Ltd., 47, Victoria Street, London. Sept. 2, 1932, No. 24552. [Class 34 (ii).] The drying of material such as peat which is moved in contact with heated surfaces while in the presence of a gaseous medium such as air is carried out in a plurality of stages operating at different temperatures, drying in a lower temperature stage being obtained by applying heat recovered from vapours of a higher temperature drying stage through the intermediary of a body of liquid in. indirect heat exchange relation with another liquid in which heat is recovered from such vapours. In the form shown, peat or other material is fed into an air stream delivered by a fan d and is carried through the tubes a<1> of a lower temperature drier a, and thence through a cyclone separator f, and so through a higher temperature drier b to the final separator f<2>. The air for the lower temperature stage is drawn from the atmosphere, to which it returns through an outlet f<1>. The air for the second stage, however, is circulated in a closed cycle by the fan d<1>, whence it passes through drier b, separator f<2>, conduit f<3>, scrubber g, direct heat exchanger h, and conduit i back to the fan to take up the partially dried peat admitted through the pipe i<1>. The water of the direct heat exchanger is circulated from a reservoir k by a pump l<1> and through the inner tube m<1> of a heat exchanger m, whence it passes to the sprays h<1> and down in countercurrent to the hot vapours back to the reservoir k. A pump l' delivers clean water to the outer tube of the exchanger m, which water passes through the pipe l<7> to heat the tubular surfaces of the lower temperature drier, and then returns to the pump. The tubes in the high temperature stage are heated by steam. Non-corrosive material such as copper containing arsenic should be used for all parts exposed to the liquid from the direct heat exchanger. By maintaining a high velocity of flow of the liquids, the temperature difference in the exchanger m may be kept small, e.g. 2‹ to 5‹ C. Specification 294,289, [Class 34 (ii), Drying systems &c.], is referred to.

Abstract: 1471316 Web inspection apparatus EASTMAN KODAK CO 4 June 1974 [4 June 1973] 24732/74 Heading G1A In a web inspection apparatus for detecting surface flaws and/or variations in thickness, comprising a series of sequentially pulsed light emitting diodes L 1  ... L n  and a corresponding series of photo diodes D 1  ... D n , the signal amplitudes and the difference between successive signal amplitudes of the output signals from each photodiode are compared with a corresponding stored set of digital data, derived from a defect free piece of web, to detect a specific surface defect or a variation in thickness, respectively. Scanning of the web is accomplished by means of a "Test Unit" 6, also Figs. 4, 4A (not shown), that controls a "Light Source Address Logic" circuit 2 and its associated power supply 1, so that each light emitting diode receives a power pulse in sequence. The sets of output signals of each photo diode D 1  ... D n  are fed via an analogue to digital converter back to the "Test Unit" 6. Calibration: A defect free piece of web is repetitively scanned as it moves past the inspection station 7 and the "Test Unit" 6 automatically determines the width of the moving web 8 from an inspection of the digital signal amplitudes received from the photo diodes. As a result, an "Address generator", Fig. 7 (not shown) in the "Test Unit" 6 is used to limit the scan width to the web width by only supplying the "Light Source Address Logic" circuit 2 with light source addresses that are over the web. Also during calibration the test unit 6 automatically converts the set of digital photo diode output signals into sets of data representing the normal amplitude variation range of each photo diode and into sets of data representing the normal range of variation in the differences between successive scan-to-scan amplitudes for each photo diode. To enable the detection of specific surface flaws and thickness variations respectively. Defect detection: After calibration, the web 8 to be inspected for defects is transported past the inspection station and is repetitively scanned. The resulting output signals of each photo sensor are converted into data that is compared with the previously determined allowable ranges and values to detect the presence of defects in the web. When a defect is found a signal F<SP>1</SP> is generated that enables a gate resulting in the contents of a footage counter 5 together with the present address in the output of the address generator to be recorded, to identify the defect's position. Additionally the defect signal may activate an audible or visual alarm. The description includes a detailed explanation of a suitable logic circuit, Figs. 4, 6, 7 and 8 (not shown), together with a formula for statistically deriving normal ranges of amplitude variations.
