Abstract: 1,106,032. Arc extinguishing in switches. E. MARX. 2 April, 1965 [2 April, 1964; 13 Feb., 1965], No. 14060/65. Heading H1N. In an arc extinguishing chamber the arc is driven by a flow of quenching liquid into a narrow gap adjacent to an insulating wall through which the arc cannot pass but the liquid can. In a first embodiment a perforated cylinder 24 is grooved, 25, to guide a bridging contact 2 mounted on the end of a second perforated cylinder 23. An explosive device 8 drives a piston 7 upwards compressing liquid above it to drive the cylinder 23 upwards at a greater speed. As the cylinder 23 enters cylinder 24 liquid blasts through channels 9 to drive the arcs drawn in grooves 25 against the wall of cylinder 24. Piston 7 moves, and therefore the blast continues, after contact 2 reaches its open position. The bore 28 of cylinder 23 is tapered to equalize blast pressure over the length of the arcs. The motion of contact 2 is damped as a piston 34 enters a bore 11. The contacts are reclosed by acting on a piston 12. In a modification (Fig. 4, not shown) the cylinder 23 is replaced by a solid piston (15); the contact 2 may be Z-shaped for higher voltages (Fig. 15, not shown). In a further modification (Fig. 9, not shown) cylinder 24 is enclosed by a jacket (44) containing a gas which is compressed as piston (15) moves upwards and provides the reclosing force. In another modification (Figs. 11, 12, not shown) a U-shaped moving contact (58) is moved in bores in the wall of cylinder (24). In further embodiments (Figs. 5, 13, not shown) the arc is drawn between contacts separating adjacent to a flat wall (24, 64). In another embodiment (Fig. 14, not shown) cylinder (63) is enclosed by a body (61) and differential pistons (62) assist the flow of liquid.

Filed: 1955-05-16
Abstract: 769,968. Selective recording machines. LINDON, J. B. May 16, 1955, No. 14092/55. Class 100(4) Relates to methods and means for printing information such as quantities and charges on a bill to a customer on one surface of a sheet or card, and for printing other information, such as name and address of customer, on the reverse surface of the sheet or card. The method may be employed in standardized types of accounting machines to print both name and address on the front of a card and bill data on the back, in an interval only a little longer than that required to type the bill data alone by replacing certain of the type bars or type wheels by others having a modified arrangement of letters and figures, and by rearranging plug and socket connections on a control panel or plug board or panel such as is usually provided on such machines. In one construction; Fig. 3, a web carrying spaced reverse carbon areas is fed through the accounting machine with the usual inked ribbon on the front, and certain of the type or type wheels which are to strike against the back surfaces of the cards or webs at name and. address areas are formed with letters of the alphabet and numerals 1-9 shaped in accordance with the mirror image of orthodox type used for printing letters and numbers and arranged so that the impressions read normally from left to right. The reversed carbon ribbon or strip is preferably continuous and driven to advance it from time to time as necessary to avoid repeated action on one locality. The usual ink ribbon of the machine may be masked or shifted to bring an uninked portion into screening position at times when name and address characters are being printed so that the impressions will be printed only in front of the carbon impressions. The machine may have type wheels provided with type or vertically reciprocating type bars, or be of a form in which the characters are printed by reeds or wires. Means are provided to deal with the case where some of the billing numerals as printed on the back of the postcard are in vertical alignment with certain of the numbers of the name and address characters which are to be typed on the front of the card by using the same carrier means for both purposes.
