A can body is made by overlapping the longitudinal edges 22 of a metal blank and welding the edges together so that the welded seam is spaced from the body ends. The seam is initially tack welded 27 between pairs of spotwelding electrodes (25), Fig. 3 (not shown), and a continuous weld formed by passing the seam through roller electrodes 26. The current to the electrodes is switched on and off adjacent the body ends. The continuous seam may terminate in a tack weld at one or both ends. The edges may be notched, Figs. 8 and 9 (not shown), so that critical current control is unnecessary. The welding current may be pulsed or continuous to heat the seam to 1400 to 2500 F., preferably 1800 to 2000 F. The can blank is coated on one side with chromate phosphate, tin or other corrosion-resistant metal, except for the longitudinal margins. The grain of the can body is preferably arranged to extend circumferentially. The blank is low carbon steel of 0À006 inch thickness although thickness up to 0À011 inch may be used.

Abstract: 1,176,014. Automatic switching systems. BOLKOW G.m.b.H. 7 April, 1967 [9 April, 1966], No. 16142/67. Heading H4K. In setting up connection over a matrix 3 of relays, the relays being of assorted type, a marker 5 selects a particular relay or relays for operation and indicates to a current supply device 1 the particular value of current required for that relay or relays, the current supply being controlled by a circuit 4 which first applies current of half the required holding value so that a circuit 2 can conduct a test on the voltage dropped across the chosen relay or relays, the current being momentarily increased to a value to operate the relay or relays, if the test is satisfactory, and is thereafter supplied at full holding current level. If the test is not satisfactory, the voltage drop across the relay or relays being greater or less than expected, the current supply is disconnected and a fault signal is generated. Selection of the current level required by each relay is indicated by connections from each relay winding to one, two, or three of the leads 11, 12, 13. The voltages appearing on these leads when a relay is selected by the marker causes corresponding resistors to be switched in parallel with, the emitter resistor of a transistor which provides the current supply. The test circuit 2 comprises two transistor voltage threshold circuits which, in comparison with the reference voltage of a Zener diode indicate whether the voltage drop across the selected relay is above or below acceptable values.

Abstract: 1416573 Carbon particles from pitch and bodies formed therefrom AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 5 April 1973 [29 June 1972 (2)] 16378/73 Heading C1A Carbon particles are obtained by heating a pitch at 300‹ to 500‹ C. for a time sufficient to form optically anisotropic spherules, removing to below 10% by weight of the remaining non-spherulitic pitch by extraction with an organic solvent, and then carbonizing the spherules in a non-oxidizing atmosphere. If desired the spherules may be graphitized, e.g. by heating above 1500‹ C. If the pitch contains no free carbon then substantially pure graphitic carbon particles are obtained. If free carbon, e.g. carbon black, is present in the pitch then spherules and subsequently particles coated with an optically isotropic carbon are obtained. High density isotropic bodies may be produced by moulding the uncoated or the coated spherules, optionally with a binder, before carbonizing the moulded products. Quinoline is the preferred organic solvent, but pyridine and tar oils are mentioned. The bodies so produced may be used in nuclear reactors or as a mechanical seal.
