Patent GB-539372-A (GB)
Abstract: 539,372. Calculating-apparatus. UNDERWOOD ELLIOTT FISHER CO. April 17, 1940, No. 6948. Convention date, June 29, 1939. Addition to 499,027. [Class 106 (i)] In a machine having a travelling carriage, two groups of totalizers, and a mechanism actuated by the carriage when moved in the tabulating direction, for conditioning a totalizer of one of the groups for operation as described in the parent Specification, the conditioning mechanism is so constructed that a totalizer may be selected for operation in both groups as well as in one group only. The carriage is formed with a control plate 7, Figs. 4 and 7, carrying a series of magazines 8 with removable lugs 91, 95 for automatically controlling the selection of the totalizers and various machine operators. The lugs act through pivoted control levers 90, 94 to depress rods 89, 93 and rock bell crank levers 87, 92. The levers 87 co-operate with corresponding yokes 38 ... 41 to condition the appropriate totalizer engaging links 47 ... 50. During a machine cycle upper and lower plates (not shown) are displaced to align studs 55, 55a with recesses in the engaging links, the selected link being raised, under its spring action, to engage its stud and effect the engaging movement. The bell crank 92 co-operates with a totalizer group slide 68, Figs. 4 and 5, operatively connected through an extension 69 and link 70 to a yoke 71 and arms 73, 75. The arm 73 is connected at its free end to a slide 77 slotted to receive the ends of the engaging links 47 ... 50. The slide 77 is operatively connected to a similar lower slide 82. In the normal position the slots are so disposed as to allow the selected one of the upper links to rise and engage its stud 55, while the lower links bear against the ends of the slots. When an upper totalizer is to be selected no lug is provided on the carriage magazine so that the bell crank 92 is not operated. If a long lug is provided the bell crank 92 is rocked and the slide 77 is depressed until the ends of the slots bear against the engaging links while the slide 82 is raised to free the lower links to ensure the selection of a lower totalizer. The provision. of a short lug 95 to operate with bell crank 92 ensures the movement of the slide 77, 82 to an intermediate position thus effecting a joint conditioning for the selection of similar totalizers in each group.

If desired, the tops and bottoms of the battens can be inclined at corresponding angles arranged so that the outer portion of each batten projects slightly above the corresponding side panel 52, or 53. In a modification instead of the panels 58, 59 being fastened to the battens by staples, the battens 54 are recessed to provide grooves with the panels 52, 53 and the panels 58, 59 are provided with auxiliary battens 69, as shown in Fig. 4, which fit into the grooves. The contents of the box hold the panels 58, 59 in position; in this construction the panels 58, 59 are also connected to the bottom panel by strips. An alternative construction is shown in Fig. 5 ; in which the panels are part of a rectangular blank 41 of sheet material such as cardboard which is provided with four cuts 42 and fold lines 43, 44 and 76 to define the bottom panel 45 the four side panels 48, 46 and four panels 49. Battens 47 are secured to the panels 46 and when the blank is erected the panels 49 are folded over the battens and secured to the panels 46 by staples. Ventilation openings 72 are provided along the fold lines 43, 44 defining the bottom panel. Additional ventilation openings 77 are provided in opposite pairs of side panels. A strengthening batten 57 can strengthen the bottom panel.

Abstract: 1294698 Lamp failure alarms HASLER AG 14 Nov 1969 [25 Nov 1968 7 May 1969] 55996/69 Heading G4N In a circuit for monitoring faults in a signal lamp control circuit having a transistor 5, controlled by a signal voltage E, a pulse transmitter 20 is arranged to deliver test pulses to transistor 5 and to a fault indicator circuit 22-26 which provides an indication if a voltage which does not correspond to the switched state of transistor 5, determined by the test pulse, occurs at the junction of transistor 5 and lamp 1. As shown, a signal at E may be passed by gates 3, 4 to turn on transistor 5 and operate lamp 1. Each test pulse A inhibits gate 3 so as to turn off transistor 5 and hence provide a pulse at the collector which is fed to a fault indicating circuit 23 . . . 26 which lights lamp 26 if lamp 1 is faulty or if transistor 5 fails to turn off. Pulses B are used in conjunction with a fault indicating circuit 33 ... 36 to light lamp 36 if an open-circuit fault should occur in gate 4 or transistor 5. AND gates 7, 8; 17, 18 couple a further lamp 11 (controlled by transistor 15) to the fault indicators. Lamp 39 indicates a fault of either type in circuits 2 and 12. The mark/space ratio of pulses A may be sufficiently small as to have no effect on the brightness of lamps 1, 11 or may be varied to provide a brightness control.

Abstract: 1285280 Printer control systems INTERNATIONAL BUSINESS MACHINES CORP 2 Dec 1970 [9 Dec 1969] 57204/70 Heading G4H A first store receives print data and document movement instructions, and a second store holds representations of characters available for printing and format instructions for use with the document movement instructions. Lines of characters to be printed and paper feed commands are transmitted by a computer over lines 12 to a register 14, the commands being routed to a command register 16, and the characters being entered in a core buffer store 20 under control of an address counter 22. A read-only store 26 comprising a capacitively-sensed punched card stores codes of all the characters available on the particular print chain in use and also stores format carriage control instructions for a number of different possible formats, the instructions indicating heading lines, lines to which the paper carriage is to skip in response to a skip command, and when the end of a document is approaching or has been reached. In a format search mode, a lines counter 40 is reset and is then driven fast until it addresses a particular heading line instruction in store 26 specified by manual setting of a selector switch. Thereafter the lines counter is advanced by one for each line moved by the paper carriage, various checks being made to ensure that carriage advance and lines counter operation are taking place correctly. The particular printer described has 144 print hammers, a belt carrying five identical sets of 60 characters, a P.S.S. emitter having four teeth per character and a home pulse emitter producing one pulse per 60 characters. On four successive subscans the address counter 22 is started at 0, 1, 2, 3 and is incremented in fours, the starting point being determined by a 2-bit counter driven by the home pulse emitter. The character codes available are stored in columns 1-60 of read only store 26 and the character counter 42 which is used to address store 26 during a print cycle is reset to 0 after a home pulse and is incremented by threes while address counter 22 is incremented by fours. The counter 42 can be in any of the 60 positions at the start of a print scan during which there are 36 cycles of memory 20 and store 26 in each subscan, these cycles being counted by counter 58. A character code is read from store 26 into register 14 for comparison with a character from memory 14 the code from store 26 being in complementary form so that if there is correspondence between the two characters register 14 then contains all 1's and compare circuit 66 enters a 1 in shift register 62.

A spun yarn comprises spirally coiled fibres, each of which is coaxial with the yarn and of substantially uniform coil diameter along its length, with the outer fibre of any pair of fibres having a smaller coil pitch than the inner fibre of the pair. As described the yarn is produced by a break-spinning method in which the fibres are sucked from front drafting rolls 5 by an air stream flowing through pipe 9 and are deposited on the inside wall of rotor 10. The wall, which may be a roughened metal plated surface, has a coefficient of friction of from .2 to .7 with respect to the bundle of fibres deposited thereon. Blended yarns may be produced by feeding a blended roving or two different rovings to pipe 9, or by having two pipes 9 feeding fibres into the rotor.
