Abstract: 1431720 Conveyers;frictional grippers CHAMPION SPARK PLUG CO 6 Nov 1973 [2 Feb 1973] 51520/73 Headings B8A and B8H Apparatus for transferring spark plugs to and from an electrode-bending work station (not shown) comprises a rotary conveyer 101, an endless linear feed conveyer 99, a transfer assembly 20 and an endless linear discharge conveyer 100. The assembly 20 comprises a series of pick-up heads 66-73 horizontally guided in slots 65 formed in a plate 24 which is vertically movable. The horizontal movement of the pick-up heads is produced by a lower cam assembly 38 which actuates a header member 61, 47 to which the heads 66-73 are connected by arm assemblies 77. An upper cam 32, by means of cam followers 37 and supports 36, raises and lowers the plate 24 and the lower cam assembly 38, the plate being vertically guided on posts 26 and counterbalanced by cylinders 42. Each pick-up head, e.g. 66 in Fig. 12, consists of arms 74, 75 normally spring-urged apart but urged into gripping position by an air pressure operated plunger 96 which in moving an upper ball 95 to the right, causes a lower ball to urge apart the upper portions of the arms 74, 75. The cams 32, 38 are on a common shaft 30 driven intermittently by a shaft 98 which also drives the conveyers 99, 100 and 101. In operation, plugs 88 are lifted from the conveyer 99, horizontally moved and then lowered into the rotary conveyer 101. Simultaneously plugs 89, having passed through the electrode-bending station, are transferred to the discharge conveyer 100. The difference in spacing between the plugs on the endless conveyers 99, 100 and the spacing on the rotary conveyer 101 is allowed for by a spring lostmotion construction on each arm assembly 77  and by the lengths and disposition of the guide slots 65.

Title: A method of producing elastomeric polymers which contain urethane groups and which are formable in solution
IPC: C08G18/10
Filed: 1965-12-13
Abstract: Polyurethanes are formed in solution by reacting an isocyanate-modified polyhydroxy compound containing at least two terminal isocyanate groups with a bifunctional chain extending agent in the presence of from 0.002 to 2.0 mols. of ammonia per mol. of the chain extending agent.  The ammonia is said to act as a retarding agent, and if desired may be added to the reactants in the form of a solid substance which yields ammonia under the reaction conditions. Alternatively the ammonia may be dissolved in water or in an organic solvent or it may be added in gaseous form.  The preferred isocyanate group containing prepolymer is a reaction product of a polyester diol and an aromatic diisocyanate and has a molecular weight between 500 and 8000.  Suitable chain extending agents are organic diamines and diols, hydrazine, hydrazine hydrate or water. The compounds which yield ammonia may be ammonium magnesium phosphate, hexamethylenetetramine, molecular sieves charged with ammonia and complex salts of metals containing ammonia.  The resultant solutions can be wet or dry spun to form filaments.

Title: Transfer means and mounting means
IPC: G06C15/04
Filed: 1969-11-04
Abstract: 1,235,230. Driving arrangements. BURROUGHS CORP. 4 Nov., 1969 [5 Nov., 1968] No. 53982/69. Heading G4B. [Also in Division F2] In a printing calculator, a sleeve 141, Fig. 2, rotatably supported on a drive-shaft 143 and carrying a series of transfer wheels 113 is given a predetermined angular oscillation during a complete revolution of the shaft 143, cams 199, 201 on the shaft 143 acting via roller followers 203, 205 to rock a frame 207A about a pivot shaft 175, a gear sector 207B of the frame meshing a pinion 209 secured to one end of the sleeve 141. The mechanism is duplicated at the other end of the sleeve. A motor 139, Fig. 1, rotates a shaft 151, Fig. 2, continuously via a shaft 167, a belt 171, and a gear 153. The shaft 143 is connectable to the shaft 151 by a one-revolution clutch 211, 215, 225 having a trip lever 227, Fig. 3, which is reset during the revolution by a cam 213, Fig. 2, to which the clutch output member 215 is pivoted. Each transfer wheel 113 is rotatably supported on a locking spacer 145 secured to the sleeve 141, a spring 191 urging the wheel angularly to hold a pin 195 thereon against a step 197 of its spacer. A bar 187 to which the springs 191 are anchored extends through an arcuate slot 189 in each transfer wheel. In operation, after an amount to be entered has been indexed on the keyboard, the plus motor bar 233, Fig. 3, is depressed to engage selector carriage wheels 131, Fig. 1, with intermediate wheels 129 and advance the transfer wheels 113 clockwise as the wheels 131 are zeroized. The wheels 131 are then disengaged from wheels 129 as accumulator wheels 21 are engaged with the transfer wheels 113. Depression of the plus motor bar also trips the onerevolution clutch, acting through a lever 235, Fig. 3, pivoted at 236, a pivot bail 237 having a pivot 239, a push-rod 245, and a plunger 259 to move collars 250, 251 leftwards. These collars are slidable on the plunger 259 and centred thereon by springs 255, 257. Initially the free end of lever 227, which has a central pivot 229, is supported on the collar 251. As the collars move leftward the tapered end of lever 227 drops between them, so that its other end rises to release the clutch member 215. A biased pin 241 on the pivot bail 237 engages an aperture 243 in the keyboard to hold the bail. The transfer wheels 113 follow the rotation of the locking spacers 145 until stopped by the zeroizing of their respective wheels 131. At the end of the clockwise rotation of the sleeve 141 and spacers 145, cams 281, Fig. 2, on the sleeve act through links 275 to move a shaft 181 away from the tails of pawls 271 so that the latter engage ratchet strips 269 on the transfer wheels 113. As the sleeve 141 makes its anticlockwise return movement, the spacers carry the transfer wheels to their zero positions, the indexed amount being transferred to accumulator wheels 21. As the movement ends the pawls 271 are lifted clear and the pin 241, Fig. 3, disengaged from the recess 243 to release the plus motor bar.
