Title: Cutting or printing presses
IPC: B41F1/26
Filed: 1959-02-20
Abstract: 914,637. Cutting-machines. CHAMBON Ltd. Feb. 20, 1959 [Feb. 20, 1958], No. 6024/59. Class 31(1). [Also in Group XVI] In a cutting press which comprises a fixed forme table 21 having a plane surface for supporting cutting elements 22, and an impression table 1 having a cylindrical surface 1a adapted to roll over the table 21 to cut by line contact therewith, the table 1 is supported at each side by links 2, 3 pivotally connected to levers 6, 7, respectively, which are rocked about their pivots 10, 11 by two cams 12, 13, respectively, fixed on a constantly-rotating shaft 14. A roller 18, carried on the impression table 1 with its axis coincident with the surface 1a, runs in guides 17 which define a cycloidal path, so that the table 1 is guided to perform a true rolling motion. Pairs of feed rollers 20, 20a are arranged to feed intermittently a web 19 of material through the press. Starting from the position shown rotation of the shaft 14 causes the table 1 to roll over the table 21 until the part of the surface 1a adjacent the roller 18 lies in the plane of operation; then the table 1 moves bodily downwards so that the surface 1a is clear of the web 19, and the feed rollers 20, 20a then feed a fresh length of web into the press. Further rotation of the shaft 14 rocks the table 1 so that it returns to the position shown on the completion of one revolution of the shaft. In a modification, the guides 17 and roller 18 are omitted, and arcuate toothed sectors on the table 1 engage racks on the table 21. A cutting tool 22 of the rib or thread type on the table 21 may cut and/or score the web 19 to form carton blanks.

Title: Test grading device
IPC: G09B3/08
Filed: 1970-02-09
Abstract: 1313113 Test grading device MINNESOTA MINING & MFG CO 9 Feb 1970 [10 Feb 1969] 6138/70 Heading G4M  A test grading device has coupled scanners reading a test sheet and an answer sheet. The two scanners are carried on a sled 22 moved by a screw rotated by a motor through reduction gears. The sheets are arranged with a stack of test sheets on base 30 held at one end by a pin and located by guides 42, 43 and the corresponding answer sheet is held in location 32. As described optical sensing is used but magnetic sensing or the use of electrically conductive material is possible. The scanning sled operates switches at each end of its travel to cause reversal of motion and at one end operates pivotally mounted legs resting on the top answer sheet to remove it from the stack when grading is complete, by tearing it from the holding pin. When the last sheet is removed a switch is operated to stop the device. The sheets (Fig. 13) have locations which are marked by the student and which are scanned and detected by reflection. Photo-cells 139 receive light reflected by the answer sheet from lamps 140 through windows 141 and the answers from the sheets are compared. In the event of a discrepancy solenoid operated pens 144, 145 are actuated to mark the sheet in a direction at right angles to the students mark thus indicating with a cross which answers were incorrect and with a line which ansers were not marked at all. Two lamps and two pens are shown so that the sheet can be marked in both directions of travel but only one pen (Fig. 15b, not shown) may be used if required. As the answers are checked a counter is operated in response to disagreements and the number of errors or of correct answers may be printed after the sheet has been read by counting up the number of errors or by counting down from the total number of correct answers. The counting wheel is reset at the completion of grading of each sheet. The answer sheet carries strobe marks 133 arranged so that they are sensed only when the answer areas 132 are not being sensed to ensure that both the answer and test sheet areas have been completely scanned. The strobe pulse ceases before scanning begins of the following area. The sensing circuit is shown in Fig. 18. Detection of a mark causes sensor 170 or 171 to deliver a " 1 " to a comparator 100 which is an Exclusive OR gate and delivers a " 1 " on line 191 when its inputs differ. The strobe 188 delivers a " 1 " pulse to a resetting device 190 and to AND gate 184 whenever the strobe marks are sensed. The resetting device resets sensors 170, 171 on removal of the strobe pulse. AND gate 184 delivers a pulse indicating disagreement while the strobe pulse exists and feeds solenoid coil 174. An alternate comparator, Fig. 19, has S.C.Rs coupled by a reed relay coil so that the relay is energized when only one S.C.R. conducts.

Abstract: 714,103. Disc brakes. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Feb. 20, 1953 [March 12, 1952], No. 6375/52. Class 103(1) In a disc brake comprising a rotatable disc 1, a pair of wishbone shaped pressure plates 9, 10 axially aligned'one on each side of the disc, a non- rotatable torque member 7 extending substantially diametrically across one side of the disc and having a pivotal connection at its ends with the extremities of the pressure plates, pads of friction material 22 secured to each plate adjacent the apex thereof to frictionally engage both sides of the disc, a cylinder 15 formed integrally with one pressure plate 9 at the apex thereof and on the side remote from the disc, a piston 16 fluid-tightly slidable in the said cylinder and means 21 extending axially adjacent a periphery of the disc to connect said piston with the other pressure plate 10, whereby an increase in fluid pressure between the piston and the base of the cylinder angularly moves both pressure plates towards the disc to effect frictional engagement between the friction pads and the disc. The piston 16 is provided with a projecting portion to which are secured two eye bolts 21 which extend axially through the adjacent pressure plate 9, extend adjacent the outer periphery of the disc 1 to which is secured the wheel 6, and have their other ends pivotally secured, by a pin 20, to the second pressure plate 10. In operation, fluid is pumped from a master-cylinder into space 17 between the piston and the base of the cylinder 15 which forces the piston and cylinder mutually away from one another. The pressure plate 9 is thus forced inwardly towards the disc 1 and simultaneously the piston, moving outwardly of the cylinder, acts through the eye bolts 21 and the pin 20 to draw pressure plate 10 towards the disc. The revolving disc being thus nipped between the friction pads 22 secured to the two plates. A hand brake mechanism is also incorporated whereby the lever arm 24, pivoted to the lugs 23 may be operated so that one end bears on a peg 25 which is slidable axially through the projecting part of the piston 16 and bears on the side of the cylinder 15 to operate the friction pads in the manner previously described. The extremities of the pressure plates 9, 10 have clearance with, and are secured by, bolts 11 fitted with rubber washers to the extremities of the torque member 7 to allow the pressure plates to pivot slightly about the bolts in the ends of the torque member.

Abstract: 565,134. Protective cut-out arrangements. STANDARD TELEPHONES & CABLES, Ltd., SCULLY, C. T., and HOUGHTON, L. W. April 23, 1943, No. 6564. [Class 38 (v)] The inverse time-limit feature of an overload relay is derived from a thermistor, the properties of which are described in Bell Laboratories' Record, Vol. XIX, p. 106. In a simple form, Fig. 1 (not shown), the relay is energized in series with a negative temperature-coefficient resistance element of the thermistor from a current transformer in the line, or if a thermistor having a resistance element of positive temperature coefficient is employed, the relay and resistance are in parallel. The response characteristics may be varied by additional series or parallel resistance, or by employing a heater connected to an adjustable and independent source. In Fig. 2, a negative temperaturecoefficient thermistor T2 has its resistance element R2 connected in series with relay RY to a source S, and its heater r2 connected to the line current-transformer CT. To control the operating current of the relay, constantload attenuators A1, A2 are included in the respective circuits, but instead of employing A2, the relay may itself be made adjustable. The relay may be of the slow-release type so as to reclose the breaks automatically after a timedelay, or arranged to be locked out after one or more operations. The Specification discusses the effects of ambient temperature and refers to time-grading in " distance " protection. Specification 251,275, [Class 37], is referred to.

Title: Improvements in the manufacture of artificial textile materials and of films and like materials having a basis of organic derivatives of cellulose
IPC: D06M13/188
Filed: 1936-04-29
Abstract: Artificial textile materials, films, and like products having a basis of an organic derivative of cellulose are esterified in a liquid non-solvent medium having a shrinking action on the materials and containing either an esterifying agent in a concentration of at least 30 per cent by volume or an organic liquid having a solvent or high swelling action on the materials but not reacting chemically with them together with an esterifying agent, e.g. in a concentration of 1,5 to 3 per cent.  The materials may be pretreated in a process of esterification with a liquid non-solvent medium containing an esterifying agent for the materials and having a shrinking action upon them.  The products have improved extensibility.  Suitable inert diluents for use in the process are benzene, toluene, xylene and carbon tetrachloride, isopropyl or other ether, tetra- or deca-hydronaphthalene, kerosene.  Suitable liquids with solvent or high swelling action are methylene and ethylene dichlorides, dioxane and methylene ethylene ether.  Treatment may be effected at ordinary temperature or higher, e.g. 30--35 DEG  C.  The shrinkage may be 3--15 per cent of the original length of the materials. Esterification may be carried out under normal or super-atmospheric pressure.  The process is applicable to ordinary yarns, e.g. produced by a dry spinning process or to yarns which have been stretched or shrunk. Stretched yarns are more resistant to esterification and to shrinkage.  Yarns may be treated as hanks or as bobbins or packages preferably having an open wind.  The yarns may be continuous or of staple fibres, and may be mixed containing in addition to the cellulose derivative, regenerated cellulose or cotton.  In an example, an acetylating medium containing carbon tetrachloride, methylene chloride, ferric chloride, 3 parts by weight of acetic anhydride and 0,5 parts by weight of acetyl chloride is circulated for about 2 hours through open wound bobbins of stretched cellulose acetate yarn free from lubricant. The yarn is dried, washed with sodium carbonate, washed and dried. In another example, hanks of stretched cellulose acetate yarn are immersed for about 15 minutes in a mixture of 37 per cent acetic anhydride and 63 per cent carbon tetrachloride.  They are then treated in a medium containing 900 parts of carbon tetrachloride, 80 parts of acetic anhydride, 1 part of ferric chloride and 1.3 parts of acetyl chloride for about 2 hours.  In a third example, hanks of cellulose acetate yarn are acetylated in a bath containing acetic anhydride, carbon tetrachloride, and small amounts of ferric chloride and acetyl chloride.  The products are suitable for use as electrical conductors or for heat and sound insulation.  Specifications 389,823, 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, 443,773, 448,816, 448,817, 448,917, and 463,323 are referred to.

The triac 27 may be replaced by a diode bridge feeding a thyristor (Fig. 2, not shown). When terminal 1 goes positive with respect to terminal 2, diode 8 would permit the primary 9 to conduct current but is prevented from doing so by the application of the positive potential at 1 to diodes 15, 18 by means of R23, R24 to hold point 14 positive relative to the potential at which the end 13 of the primary is held by the potential dividing action of R10, R12 and the negative voltage at 5. Only when both inputs 3, 4 go negative do diodes 15, 18 block, and diode 8 then conducts to energize the primary. A rectifying diode 29 and smoothing capacitor 32 generate the gate trigger voltage for triac 27.
