Title: Improvements in or relating to methods and means for stiffening and performing work on fabrics
IPC: D06C29/00
Filed: 1967-12-22
Abstract: 1,202,550. Folding edges of and seaming non-metallic sheet material. UNION SPECIAL MACHINE CO. 22 Dec., 1967 [27 Dec., 1966], No. 58397/67. Addition to 1,154,382. Heading B5K. [Also in Divisions B2 and D1] The edges 280 to 283 of a fabric pocket blank 279 are folded over and impregnated with a heated and molten organic compounds such as para-dichlorbenzene, which on cooling in situ in the fabric serves to stiffen and to bond together the two plies constituting the folded edges. After work, such as sewing, has been performed on the stiffened edges, the stiffening agent is removed by heating. In the apparatus shown, an outer container 30d, lined with insulation containing a heating coil 46d, supports an inner container 37d for molten stiffening agent 38d maintained at a temperature slightly above its melting-point by a thermostat 40d. Container 30d is closed by a plate 166 formed with a cut-out 173 conforming in shape to but slightly larger than blank 279. Container 37d is closed by a plate 51d formed with a U-shaped slot-like cut-out 53d conforming to the edges 280 to 283, slots 133d extending outwardly from cut-out 53d to define resilient tongues 134d, and a slot 175 defining resilient tongues 176, 177 within the arms of the cut-out 53d. Plates 201 to 204, slidably mounted on plate 166 by pin-and-slot connections 207, 209, have respective inner bevelled edges 206 conforming to the sides 283, 282, 281, 280, respectively. Plates 201 to 204 are biased inwardly by respective springs 220. A rigid and porous applicator 70d, partially immersed in agent 38d, is formed from sintered brass and is supported by the base of container 37d and comprises vertical walls, the exposed upper edge surface 74d of which is located below and in alignment with the cut-out slot 53d. Plate 166 carries brackets 272, 273 journalling a rod 269 which is rigid with an arm 97d biased to the raised position by springs 274, 275. A body 245, slidable in a slot 247 formed longitudinally in arm 97d, is biased to the inner end of slot 247 by a spring 260, and is pivoted by a pin 242 to lugs 240 upstanding from a plate 98d having bevelled edges 228 conforming to the edges 280 to 283. In operation, a blank 279 is laid upon plate 51d within the edges 206, and arm 97d is lowered. The edges 228 thereby cooperate with the edges 206 to move the plates 201 to 204 outwardly, blank 279 is pressed against surface 74d, kept wet by capillary action, by plate 98d, and the plates 201 to 204 move inwardly to fold the edges 280 to 283 over the edges 228. Body 245 is then shifted to the outer end of slot 247 to disengage plate 98d from blank 279, when the plates 201 to 204 complete their inward movement to fold the edges 280 to 283 upon the body of blank 279. Body 245 is then released and arm 97d is again lowered, whereby the plates 201 to 204 are again moved outwardly and the folded-over edges 280 to 283 are pressed between surface 74d and plate 98d to complete impregnation thereof.

Abstract: 1414149 Spring applied electromagnetically released disc brakes; wear adjustment; friction clutches ZAHNRADFABRIK FRIEDRICHSHAFEN AG 20 Dec 1972 [24 Dec 1971] 58765/72 Headings F2E and F2C A spring-loaded brake or spring-loaded clutch includes an automatic wear adjusting device comprising a compression chamber 20 filled with an hydraulic fluid and a pressure piston 21 having an orifice 22 in which a valve cone 23 with a valve rod 24 is positioned, and during a brake actuation when there is excess play the piston 21 is urged against the fluid in chamber 21 and fluid is forced out of chamber 21 through the orifice 22 against the valve cone 23. The illustrated embodiment shows an electro - magnetically released spring-actuated brake comprising an armature plate 1, a magnet element 2 and a plurality of compression springs 3 and adjusting devices arranged around brake housing 4. The magnet element 2 is axially slidable in a guide sleeve 5 attached to the armature plate 1 and is secured against rotation by bolts 7; the springs 3 urge plate 1 towards a brake disc 8. The armature plate 1 is connected to the pressure piston 21 via a flange 9 of the guide sleeve 5 and a sleeve 25 mounted on piston 21. The valve rod 24 protrudes through the sleeve 25 and the flange 9 of the guide sleeve 5. When current to the coil is switched on, the magnet element 2 moves toward the plate 1 until a flange 6 rests on valve-rod 24 and then plate 1 moves towards element 2 to abut the latter. When the current to the coil is switched off, the armature plate 1 is urged by springs 3 to abut disc 8 and if disc 8 is worn the flange 9 urges the piston 21 against the fluid in chamber 20 to force fluid out through orifice 22 against cone 23 and adjust the air gap 11. The hydraulic medium is preferably a viscous material. The device may also be used in a spring- loaded electromagnetically released clutch.

Abstract: 1451340 Photographic type-composing MINNESOTA MINING & MFG CO 21 Dec 1973 [26 Dec 1972 15 Oct 1973] 59472/73 Heading B6W [Also in Division G2] Characters are printed in succession on a receiver web by imagewise transfer of pigment from an adjacent donor web under the action of heat from a flash lamp 19 while the web assembly 12, after manual positioning, is clamped between an image window 20 in a highly reflective coating on a template 22 and a plunger 88. Template 22 comprises two concentric arrays of characters, each being surrounded by a transparent area having character alignment marks 190, and is in the form of a replaceable disc on a turntable 134 having two sets of peripheral notches, each corresponding to a character. Template 134 is rotated and/or laterally moved manually by means of a knob 141 to bring any desired character window to the exposure station. It is also manually adjustable laterally with respect to web 12 by means of an indicator blade (164, Fig. 5) and a knob (158). To enable access to web rolls 40, template 22 is situated during exposure between pivotal support members 35 and 36, the latter carrying a pivotal flash lamp 19, a transparent exposure plate 16 and a transparent viewing plate 46. Manual lowering of lamp 19 for an exposure precisely locates the turntable by the engagement of a pawl (168, Fig. 10) with a turntable notch, raises plunger 88, and causes a flash. A further exposure is effected after manual advance of web 12 (by means of a knurled wheel 57) to line up a newly formed character under a mark 190 (visible through plate 46). In a modification (Figs. 12-19), the template has no alignment marks and consequently no outer transparent area, but is movable (caused by the lowering of lamp 19) from a see through position, for lining- up a character with a line (340, Fig. 13) on the exposure plate, to an adjustable exposure position.

The methanol is evaporated off, the residue triturated with ether and dried. The resulting crude solid is purified by chromatography with methanol on dextran gel, the active fractions being evaporated and chromatographed on silica gel or alumina with chloroformmethanol, ethyl acetate-methanol or ethyl acetate alone. Alternatively, the said active fractions may be chromatographed on cellulose with water-saturated methyl isobutyl ketone. The pure crystalline antibiotic is obtained by evaporation of the final solution.

Title: Signal amplitude limiting circuits
IPC: H03G11/00
Filed: 1940-04-18
Abstract: 542,077. Wireless receiving apparatus. PHILCO RADIO & TELEVISION CORPORATION. April 18, 1940, No. 7028. Convention date, May 13, 1939. [Class 40 (v)] An arrangement for limiting the amplitude of undesired signals comprises a tuned coupling transformer the input of which is shunted by a biased diode, and the output of which is shunted by a diode having in series with it a resistance shunted capacity. As shown, a high frequency valve 3 is coupled by a double tuned transformer 4 to signal utilization means having input terminals X, Y. The primary 20 is shunted by a diode 5 biased by resistance 11, while secondary 23 is shunted by a diode 6 in series with a circuit 22, 24. Noise impulses of greater than a predetermined amplitude cause diode 5 to conduct to short circuit the primary 20. Also the time constant of 22, 24 is made large enough so that impulses of steep wave front cause diode 6 to conduct and short circuit the output circuit. This increases the impedance of the tuned primary circuit presented to valve 3 and hence a higher voltage appears across the primary. This will cause diode 5 to conduct even for signals of a lesser amplitude than would cause it to conduct in the absence of diode 6.
