In addition up to 50% iron powder, ferro-chromium, nickel, copper, are stabilizing compounds such as barium or strontium carbonate and silica can be included. Such additions may be included in the following coating for use in "position" welding:-20-65 rutile, 1-8 fluorspar, 0-30 felspar, 0-10 limestone, 2-30 ferro-alloys, 0-5 clay. For welding steel containing 4-6% chromium and 0.5% molybdenum a suitable coating is:-35 rutile, 10 fluorspar, 12 felspar, 8 limestone, 16 ferro-manganese, 2 ferro-silicon, 8 ferro-titanium, 22 ferro-chromium, 3 ferro-molybdenum. For depositing weld metal containing 2-3% nickel the coating is:-50 rutile, 10 fluorspar, 12 felspar, 8 limestone, 10 nickel, 15 ferro-manganese, 3 ferro-silicon. For welding 18/8 stainless steels, the coating may be as follows:-20-50 rutile, 8-20 fluorspar, 0-10 felspar, 5-20 limestone, 5-10 nickel, 0-10 ferro-niobium, 10-25 ferro-chromium.

Patent ES-347299-A1 (ES)
Title: Container handling system
IPC: B65B35/26
Filed: 1967-11-17
Abstract: Carriers 44 on a turret 40 move selected containers C out of their path on a conveyer 32 and upwards into engagement with a sealing head (46) (Fig. 3, not shown), each non-selected container C moving on to a support 120 of the turret 40, there being deflecting means carried by the turret to deflect the non-selected container from the support and so maintain it in the conveyer path. In Fig. 2 alternate containers are selected, the remaining containers being fed to a second turret 42 similar to the turret 40. The selected containers are engaged between a semicircular shaped recess on a plate 208 rotating with the head 40 and a similar recess on a wheel 211. The heads 40, 42, wheel 211 and a recessed wheel 186 co-operating with the head 42 are all driven by gearing (Fig. 5, not shown) in synchronism with the conveyer 32. The non- selected containers arrive at the head 42 in time to be engaged by a recess 208 having a profile of combined concave and convex form which is adapted to deflect the container of the support 120 and thus maintain it on the conveyer 32. In a modification (Fig. 19), the non-selected containers C2, C4 . . . are engaged by an arm 233 which is pivotally mounted on the platform 120 by a pin 236. The arm 233 is deflected by the action of an arm 242 which at one end carries a pin 239 engaging a slot 238 in the arm 233. At its other end the arm 242 is rigidly connected to a shaft 243 which is connected to an arm 244. The latter has at its other end a cam follower 245 which rides in a circular cam track 246 formed in a fixed part of the apparatus. This has a reduced diameter section which causes the arm 244 to be deflected at the appropriate moment. An alternative form of this modification is also described (Figs. 12-16, not shown).

Title: Feed control for stuffer crimper
IPC: D02G1/12
Filed: 1968-10-09
Abstract: Apparatus for crimping yarn comprises a stuffer crimper having a crimping chamber 10, means feeding yarn 16 into one end of the crimping chamber to be crimped against the mass of previously crimped yarn in the chamber, means including a switch 49 having magnetically operated contacts for controlling the relative rates of feed and withdrawal of the yarn from the crimping chamber, means including a feeler 45 adapted to rest on a core of crimped yarn in the chamber to rise and fall therewith, and a magnet 50 mounted for movement with the feeler in a path to open and close the contacts of the switch 49 in response to movement of the magnet 50 which is arranged such that the magnetic force for actuating the contacts is applied in a direction transverse to the path of movement of the magnet, whereby any reactive force on the magnet is not transferred to the feeler means and does not affect the back pressure thereof on the core of crimped yarn. The chamber 10 is formed by tubes 10 and 10a extending through a sleeve 10b. The feed means comprises a pair of rollers 14, 15, the roller 14 rotating on a fixed axis 17 and the roller 15 being mounted in a bracket 30 movable relative to a pivoted bracket 32 to vary the bite spacing of the rollers and to adjust the parallelism of the rolls. The switch 49 energises a solenoid 25, the plunger 26 of which engages a disc 27 adjustably mounted on a pivoted link 22 to move the link against a spring 23 and reduce the tension on the driving belt 19 for the roller 14 to reduce the speed of that roller. In this way the level of the mass of crimped yarn in the chamber 10 falls and the contacts of the switch 49 are opened by the movement of the magnet 50. The speed of the roller 14 then returns to its initial speed.
