Title: Dimpling tool
IPC: B21D22/04
Filed: 1943-10-12
Abstract: 568,861. Flanging. CHICAGO PNEUMATIC TOOL CO. Oct. 12, 1943, No. 16703. Convention date, Jan. 11, 1943. [Class 83 (iv)] A dimpling-gun, of the type in which a pin passing through the work and carrying the counter die is gripped by chuck-like jaws in the gun, is provided with a resilient pad for applying pressure to the work in the immediate vicinity' of the die to prevent wrinkling, and with a centralizing guide that directs the pin through the dimpling die. The rod 38 of the operating 'piston carries a taper sleeve 58 enclosing jaws pressed to grip the serrated shank of the pin 29 by a, plunger 59 and spring 62. The end 64 of the dimpling-die 63 holds the jaws open, to receive the pin, in the at-rest position of the gun. Pads 68 are carried by extensions from a sleeve 25 sliding on a sleeve 71 confined between a shoulder 84 of an extension 54 and a circlip 85. As the gun is advanced to the work, the sleeve 25 is pressed back against the pressure of springs 73. Arms 75 that form a guide 78 to lead the pin into the bore of the die 63 are mounted on rock-shafts 76 in the sleeve 71 and carry followers 81 running in cam grooves 82 in the sleeve 71. The initial movement frees the arms 75 from locking stops 87, adjustable at 88, and then an inclined part of the cam groove swings the arms clear of the die, a straight part of the groove holding them in this position during the completion of dimpling. A screw and slot prevent relative rotation of the sleeves 25 and 71 during the sliding movement. A rubber or like resilient pad 89 is mounted on the nose of the die 63 and is more or less masked by a sleeve 69 adjustably secured on the extension 54. Graduations are provided to set the sleeve 69 according to the amount of pressure required, the more the pad is masked the greater the pressure exerted. A detent 94 controlled by a spring 96 retains the parts in the adjusted position. The part 91 carrying the detent notches and some of the graduations is adjustable on the sleeve 69 and is locked after adjustment by a nut 92. This adjustment enables the tool to be set by comparison with a master tool so that the pressure corresponding to a particular graduation has a standard value.

Abstract: 111,301. Breton, H., and Breton, R. Nov. 15, 1916,- [Convention date]. Bore-hole apparatus. - Relates to machines which cut their way through the ground automatically when supplied with power as by electric cables from the starting point, and consists mainly in providing these machines with a belt of cutting blades which excavate the ground in front of the machine and throw the excavated material behind as the machine advances. In the subterranean torpedo shown in Fig. 1, an endless belt a of cutting blades is driven by the motor p<1> through worm gear q<1>, bevel-gear r<1>, screw spindle c, worm gear s<1>, t<1>, and toothed wheels b. At the same time, a number of spring-controlled feet 1, 2, Figs. 4 and 5,-two on each side-are reciprocated to move the torpedo forward step by step, while the belt scoops earth from in front and delivers it behind a spring controlled hinged rear plate g. The feet are driven forwards by linkwork u when a half-nut w<1> on the block w is in engagement with the screw spindle c<1>, and the feet are moved back by springs q, q<1> when the half-nut is disengaged. The half nut is alternately thrown in and out of engagement at the end of each stroke by bevelled collars on a sliding rod n<1>, which is displaced longitudinally by its alternately abutting against the bevel gear r<1> and a fixed block f<1>. The torpedo is supported in front by a plate h<1> and behind this by rollers g<1>; and the belt is protected by side disks f on the wheels b, and by fixed flauges e along the sides of the torpedo. The electric cables enter the torpedo through holes at the rear end of the side walls, and are connected to and wound on drums b<1>, Fig. 2, against which bear contact shoes i' connected to the motor p<1> and to the detonator j<1> respectively. The cable for the motor is shorter than the other and breaks at a given point when it is completely unwound. The stoppage of the propelling current indicates that the torpedo has completed its travel.

Title: Method of wet cleaning of natural fibres from impurities  and wool sweat and apparatus for performing this method
IPC: D06B13/00
Filed: 1973-04-07
Abstract: 1395288 Apparatus for cleaning fibres TSENTRALNOE PROEKTNO - KONSTRUKTORSKOE I TEKHNOLOGI - CHESKOE BJURO LEGKOI PROMYSHLENNOSTI and TSENTRALNY NAUOHNO - ISSLEDOVATELSKY INSTITUT SHERSTYANOI PROMYSHLENNOSTI 7 April 1973 16804/73 Heading D1L Natural fibres are cleaned and freed from wool sweat by positioning in a vessel a mixture of the fibres and liquid in a space between a pair of electrodes mounted within the vessel in opposition to each other and subjecting the mixture to shock hydraulic waves by creating a pulse electric discharge of from 20 kilovolts to 70 kilovolts and a single energy discharge of from 0.1 kilojoules to 12 kilojoules between the electrodes. Two forms of apparatus for carrying out the invention are described which differ in construction depending upon the nature of the fibres e.g. their adhesion to each other. In Fig 4 the wool fibres to be cleaned are mixed with water and are changed into a chamber 1 through a changing aperture 2, the mixture moving in a continuous stream along the passage 3 of the chamber which has at opposite sides thereof widened portions 4. In some of the widened portions are positioned pairs of electrodes 5 and 6 supplied with 20-70 kv from a pulse current generator which gives a discharge lasting several microseconds and creating a plasma channel in the surrounding water. The resulting shock wave disintegrates solid foreign matter and emulsifies fatty impurities. An intermediate fibre flushing stage is provided where the impurities are removed and clean water is added through the perforated wall 7 into the passage 3. As shown in Figs 7 and 8 effective cleaning of fibres characterised by a high degree of adhesion to one another is effected as follows. The fibres are changed into the passage 10 through the opening 11 wherein the fibres are engaged by blades 12 which advance them along the passage 10 by means of a drive system attached to the movable lid 13. The blades 12 divide the passage 10 into sections 14, each section has an electrode 15. Water is supplied into the passage 10 through tube 16. When the electrodes are connected to a source of voltage a discharge takes place between the electrodes and the lather 17 of the passage 10 which results in the cleaning operation being performed individually in each of the sections 14.
