Title: Improvements in Apparatus for Twisting Wire Ties or Forming Loops at Ends of Wires.
Inventor: CRANK THOMAS
IPC: B21F1/06
Filed: 1917-08-21
Abstract: 119,258. Crank, T., and Lee, H. P. Aug. 21, 1917. Twisting wires together.-In a machine for making loops at the ends of wires, the free end is bent back on itself around a twisting hook by a crank-pin; the wire is then clamped, and the hook rotated. The wire may be folded on itself by hand, but preferably by a pin 25, which is moved to bend the wire round the hook 7 by means of a crank 22, pulley 26, and cord 27 operated by a treadle and spring. The two parts of the wire are then clamped between jaws 8, 9 by a lever 10 which also operates a lever 15. link 14, spring 16x, and lever 11 to press the driven clutch member 12 into engagement with the spindle 3 carrying the hook 7 which thereby twists the wire. To avoid undue tension during twisting, the hook is adapted to move to the right a little against the action of a spring 20. When the twist is complete, the handle 10 is returned by hand or by the spring 16<x>, the jaws 8, 9 release the wire and the hook 7 comes to rest. To ensure that the end is directed towards the device 25, a notch is formed in the flange 19<x> to be engaged by a lever 28 which is moved into and out of position by a lever 30 actuated by the handle 10. If desired, the hooks 7 &c. may be duplicated, both ends of the wire being formed into a loop at the same time.

Title: Method for the manufacture of a neutron source
IPC: G21G4/02
Filed: 1974-03-19
Abstract: 1458900 neutron sources; their manufacture and re-generation KERNFORSCHUNG mbH GES FUR 19 March 1974 [24 March 1973] 12031/74 Heading G6P A neutron source is made by (a) treating a porous, shaped body of ceramic material with a liquid or gaseous medium comprising a carrier and a neutron-emitting substance (e.g. Cf-252), (b) removing the carrier, (c) heating the body to convert the substance to its oxide, and (d) enclosing the body in inner and outer metal shells. A neutron source having a neutron-emitting substance dispersed in a porous ceramic body can be re-utilized after treatment to extract the substance and/or its daughter products, to cleanse the body and, by applying steps (a)-(d) above, to re-generate it. Two constructions of source made as above are described. In one (Fig. 1) the body 1, inner and outer shells 2, 3 are thin, elongate needles so that the source may be used in interstitial and intracavitary radiation therapy. In the other (Fig. 2) the body 5 is a pellet-like cylinder enclosed in inner and outer shells 6, 8 each with a lid 7, 9, the lid of the inner shell lying adjacent the base of the outer shell. Various other shapes can be given to the body.

Title: Process for the production of urethane polyisocyanates
IPC: C08G18/80
Filed: 1958-04-24
Abstract: In a process of producing urethane polyisocyanates having a high content of available -NCO, but which do not emit toxic vapours, by reacting an organic di-isocyanate with a polyhydric alcohol, the proportions of the two reactants being such that there is more than 1 mol. of di-isocyanate for each hydroxyl group of the polyhydric alcohol whereby the formation of polymeric products of high molecular weight is minimized, the liquid reaction mixture is extracted, preferably at a temperature between 50 DEG  C. and 130 DEG  C., with a liquid aliphatic and/or alicyclic hydrocarbon, or a mixture of such hydrocarbons, in order to dissolve out unreacted di-isocyanate from the urethane polyisocyanate product.  Hexanes, cyclohexane, the alkyl cyclohexanes, heptanes, octanes, gasoline fractions and synthetic hydrocarbon fractions are the preferred extraction media.  In an example, a mixture of toluylene-2,4-di-isocyanate and toluylene-2,6-di-isocyanate is heated to 90 DEG  C.; and a mixture comprising trimethylol propane and 1,3-butylene glycol is added over a period of 2 1/2 hrs. while maintaining the temperature at about 88 DEG  to 100 DEG  C.  The resulting urethane polyisocyanate, dissolved in excess toluylene diisocyanate, is then extracted with a solvent (boiling range 315-390 DEG  F.) comprising about 88% paraffins and naphthenes and about 11.5% aromatics.  The extraction is carried out in an externally heated vertical column divided into seven sections, each containing a turbineagitator. The polyisocyanate is fed continuously into the top of the column, while the solvent is introduced into the bottom; the temperature of the column being held in the range of 100 DEG  to 116 DEG  C.  The extracted product, withdrawn from the bottom of the column, is heated in vacuo to remove solvent.  The final product is an amber solid which contains 18.5% available NCO.  Other polyhydric alcohols which may be reacted with organic diisocyanates are: pentaerythritol, triethanolamine, neopentyl glycol, and castor oil.  It is also possible to use, together with the polyhydric alcohol, a small amount of a higher-molecular polyhydroxy compound, such as hydroxyl polyesters or hydroxyl polyethers.
