Title: Apparatus for the fabrication of tubular structures
Inventor: NAKAMURA TAKASHI
IPC: B21D5/06
Filed: 1969-11-14
Abstract: 1283951 Drawing DENGENSHA SEISAKUSHO KK 14 Nov 1969 24642/69 Heading B3P A tube is formed by passing a strip 5 between a base-plate 4 and a guide-plate 8, which are convergently tapered in the direction of advance of the strip, so that as the strip passes between the plates 4 and 8 the lateral edge parts of the strip are progressively exposed and are bent by surfaces lc and 1d of a member 1. In another embodiment (Fig. 6) the frictional forces are reduced by replacing the member 1 by two inclined rows of rollers and the curvature of the tube can be varied by yieldably supporting the base-plate on an air cylinder and adjusting the vertical position of the guide plate. Similarly, the rollers can be mounted on blocks which are movable in the transverse direction. The rollers can also be mounted eccentrically so that the parts of the strip which contact the rollers receive a percussive force. In another embodiment, Fig. 11, the rows of rollers and base-plate are replaced by an elastic belt 112 movably mounted on a base 111 and having an upper run 112a which travels along the upper surface of the base in synchronism with the strip under the guidance of a roller R. The strip is subjected to bending forces by a guide plate 14 and to the resulting deformation of the upper run of belt 112. In another embodiment, Fig. 15, the strip is fed between a guide plate, having rollers on the strip engaging surface, and guides 122 mounted on a conveyer 121 and having slides 123. As the strip advances the slides 123 are cammed so that they pass along the edge parts of the guide plate during the passage past the latter.

Abstract: 1304297 Toy tracks MATTEL INC 19 April 1971 [15 Dec 1970] 24657/71 Heading A6S A toy device usable with an upstanding track loop 14 comprises a frame 10 and a switch member 12 slidably mounted on the frame. The device has five track holders 16, 18, 20, 22 and 24 to hold the ends of track sections, the holders 20 and 22 being mounted on the switch member 12. When assembled one end 30 of the loop track 14 is engaged with track holder 18, and the other end engaged with track holder 20, track sections of the remainder of the layout being engaged with track holders 16 and 22. When a toy vehicle moving in the direction of arrow 34 reaches the device, it enters the loop by end 32, and exits from the loop by end 30; however, if the switch member 12 is moved to abut a stop 90, the two ends of the loop 14 are aligned and the vehicle will move repeatedly around the loop. The track holder 24 is only used if a twisted loop is required.

Abstract: 616,020. Friction and positive clutches. TARLTON, F. H. Aug. 19, 1946, No. 24683. [Class 80 (ii)] In a friction or otherwise synchronized positive clutch of the kind in which a lug 16, Fig. 1, on the positive clutch operating member 12 engages a longitudinal slot 17 in a barrel 18 and in which balking notches 20, Figs. 2 and 3, are provided in the slot having cam sides coacting with mating faces on the lug, one or both of the coacting surfaces of the notch and lug are resiliently pressed together to avoid backlash and are provided with a fixed abutment which locates them when the cam surfaces are required to be operative. As shown, applied to a double-acting positive clutch having synchronizing friction cones on the barrel 18, the lug is held centrally in the slot 17 by spring means. In one form, a spring 22, Fig. 2, embracing the lug and fitting the slot closely at either end, has faces 23 co-operating with the notches 20. In another embodiment, the notches 20, Fig. 3, are themselves formed on sliding members 24 spring-pressed into engagement with the lug and movable to abut the barrel 18 solidly when the notches are aligned with the sides of the slots. The members 24 are prevented by shoulders 27 from protruding too far into the slot and have chamfered ends to facilitate entry of the lug between them.

Title: An improved process for recovering noble metals from refractory minerals
IPC: C22B11/00
Filed: 1958-07-31
Abstract: Refractory metal bearing material which contains sulphur, at least one noble metal, e.g. Au, Ag, Pt, Pd, Ir, Rh, Ru, or OS, and at least one of the group lead, arsenic, and antimony, is heated in a comminuted state in an inert atmosphere at a temperature above 470 DEG C. but below the fusion temperature to remove at least part of the As and/or Sb and sulphur by distillation.  The roasting residue is slurried in water or an aqueous H2SO4 solution, the slurry is agitated and heated to maintain a temperature of 90-190 DEG C. under an oxygen partial pressure above one atmosphere to convert at least part of the S to liquid sulphur globules containing unoxidized metal-bearing particles, the sulphur globules are solidified and returned to the heating step, and noble metals are recovered from the slurry residue.  The heating step is effected at 470-820 DEG C. in an inert atmosphere, and the residue is cooled to below 100 DEG C. out of air contact by quenching with water or weak acid, or by passage through a cooler.  The residue which should be 0.147-0.043 mm. size may contain pyrrhotite, undecomposed arsenopyrite, pyrite, antimony and lead minerals, noble metals, and decomposed chalcopyrite, and pentlandite, and is slurried in water or water containing 1-10 grm. H2SO4/l.  The slurry is heated under O2 pressure 1-7 atms. to yield a solution which may contain soluble sulphates of Ni, Cu, Zn, and Co, and an insoluble residue of Fe2O3, ferrous, and ferric, sulphate, insoluble arsenates and antimonates, gold, and lead sulphate. Where the slurry is heated below 112.8 DEG C. the temperature is raised above for agglomeration of the liquid S globules containing occluded antimony and lead sulphides.  The S particles are cooled and separated and returned with, or without preliminary drying and/or grinding to the roasting where S vapour is recovered. Part of the S globules may be treated separately, e.g. by burning, and occluded metals returned to the roasting, or oxidation.  The residue from the S separation is neutralized with lime and cyanided by mixing with water and reacting with NaCN to recover gold, or silver.

Each coin tube may consist of a tube 33, Fig. 5, carrying the coins and slidable within a main tube 32 which is graduated, the tube 33 being secured to a socket 34 mounted in the socket 7, and relative rotation between the tubes prevented by a, pin 36 engaging a slot 37. A detachable pin 38, inserted in the bottom of the tube 33, permits removal of the loaded tube without danger of spilling the coins A washer placed on the pile of coins in each tube carries a pointer 40 which moves over the graduated scale on the tube 32. In a modified construction, the coin tubes are disposed in a vertical plane perpendicular to the vertical plane of the keys, each slide being controlled by an additional bell-cranked lever carried on a diagonally-disposed plate. The slide may then be provided with vertical partitions extending as far as the plate 2.
