Abstract: 987,193. Selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 25, 1964 [June 7, 1963], No. 22707/63. Heading G4H. A transducer head 12 is positioned relative to a magnetic drum 13 in accordance with information punched on tape 1. Light passing through holes in tape 1 falls on photo-cells 5, and a shutter tape 8 bearing opaque code areas is driven until the light is obscured from all of photo-cells 5, head 12 being positioned by draw-member 9 at the same time. The code areas on shutter 8 are arranged as shown in Fig. 3, the first part having a single opaque area 17 in the different positions in turn, then different combinations of two, and then combinations of three, and so on. The width of areas 17 is such that no ambiguity arises on changing from one position to the next. In alternative embodiments the desired position of head 12 is represented by electrical signals which are used to block the outputs of certain of cells 5, and shutter tape 8 is replaced by a disc or drum. The shutter may be returned to its initial position immediately after the desired position is reached, head 12 being retained by pawl 15 until it is released separately.

Title: Method of and apparatus for testing the extent to which cartridges of ball-point pens are filled
IPC: B43K7/04
Filed: 1957-07-17
Abstract: 809,997. Sorting apparatus. CASTELL, G. R. FABER-, [trading as CASTELL, A. W. FABER-, [Firm of]]. July 17; 1957 [July 27, 1956], No. 22711/57. Class 117 [Also in Groups XVIII and XXXVIII] Cartridges of ball-point pens are sorted into those which are adequately filled and those which are not sufficiently filled by blowing a stream of air across the open end of each cartridge and separating those cartridges which produce a whistling tone above a certain frequency from the remainder. The cartridges 7 to be tested are stored in a hopper 6 from which they fall one by one into recesses 19 in the surface 9 of a drum 2. The drum is intermittently turned through an angle corresponding to that between the recesses by a ratchet wheel 3 driven by a pawl 4 which is reciprocated by rotation of a crank disc 16 through a push rod 5<SP>1</SP> and a lever arm 5. During the idle stroke of the ratchet, the drum is held fast by a spring 22, in which position a cartridge is presented to a stream of air from a nozzle 12 which is supplied through a pipe 13 from a bellows 14. The bellows is driven from the crank disc 16 so that the air stream is produced only while the cartridge is in position in front of the nozzle., If a whistle tone of low pitch, indicating a low ink level in the ink cartridge, is heard by the operator, he depresses a lever arm 26 causing an arm 25 to eject the faulty cartridge into a receptacle 29. Correctly filled cartridges fall into a receptacle 30. The ejector arm may be actuated automatically when a low whistle tone is generated by an electric system (see Group XXXVIII).

Title: Machine for the purpose of manufacturing the outer covers of pneumatic tyres
IPC: B29D30/34
Filed: 1936-08-19
Abstract: 467,709. Tyre - building machines. DUNLOP RUBBER CO., Ltd. Aug. 19, 1936, No. 22805. Convention date, Aug. 21, 1935. [Class 144 (i)] In a tyre-cover building machine of the kind in which strip material is wound from a spool rotated in an oblate path about a pair of spaced bead wires, each orbit of the spool is made in a series of separate motions, preferably two arcuate motions and two (intermediate) linear motions. In the machine shown, a main driving-shaft c carries a pair of slotted cam discs 17, 61 from which linkage-gear is operated for transmitting intermittent motions to the spools 1 and bead-wires 60, 60<1>. The cam 17 actuates links 16, 15, 14 for reciprocating a slide 12 fitted with a rack 19 with which meshes a pinion 20 on a vertical shaft 21. A pinion 22 on the upper end of this shaft meshes with racks 23 on slides 2 by which the reciprocations of the spools across the spaced wires is effected. The cam 61 actuates, through links 62, 63, 64, 65, a rack 46 meshing with pinions 45 on shafts 66 the oscillations of which are transmitted to arms 40 supporting the spool-carriers 7. The latter are alternately actuated by the slides 2 and arms 40 for effecting the intermittent linear and rotary movements respectively. For effecting the linear movements, the slides 2 are fitted to a rod 8 linked to arms 67 on a plate 69 which is carried by a vertically-reciprocating shaft 70. During its to-and-fro movements, the rod 8 actuates links 9, 10 by which the spool-carriers are clutched to the slides 2. At the end of each of these movements, the spoolcarriers are disengaged from the slides and clutched to the arms 40 the rotary movements of which are then effected by mechanism comprising a vertically-reciprocated plate 48, collars 41 on shafts 66, links 55, 54, 51, and a rod 8<1>. The bead wires 60, 61 are mounted over a lower set of idler rolls 34 and an upper set of rolls comprising idlers 33 and drivers 32 geared to a ratchet-transmission 28, 29. The latter is intermittently actuated from the slide 12 by a link 27 pivoted on a slide-block 25 which is guided in a frame 26 carried by a plate 12a. The desired speed-ratio between the advance of the bead wires and the linear traverse of the spools is obtained by angular adjustment of the plate 12a on the slide 12 whereby the effective throw of the slide 25 is varied. Fig. 7 shows a spool structure comprising a sleeve 72 secured by a catch 72<1> to an inner sleeve 73<1> which is rotatably mounted on a boss 75 having a lug 75<1> for attachment to the spool-carrier 7. For maintaining the desired tension in the strip being unwound from the spool, an adjustable spring 75<3> is arranged to press a flange 73<2> at the end of the sleeve 731 against a flange 75<4> of the boss 75 to brake the rotation of the sleeves 73<1>, 72.

[Class 38 (iv)] Temperature.-In an automatic temperature control system for an enclosure, the heating means for the enclosure is connected in the feedback path of an electric oscillator and includes one or more thermistor temperaturevariable resistors. In the arrangements described the output and input of an electric amplifier are coupled to form an oscillator through a bridge network composed of four resistances. In one arrangement two thermistors having temperature coefficients of the same sign, forming opposite arms of the bridge, function as heaters for an oven or enclosed space the temperature of which is to be maintained constant, while two other resistances of zero or nearly zero temperature coefficient form the other arms. The stabilized temperature is less than the temperature at which the bridge would balance and temperature deviations are automatically corrected by the consequent variations in oscillator feed-back amplitude. The oscillator frequency may be fixed by a frequency determining circuit in the amplifier or feed-back path. The amplifier may be provided with negative feedback and amplifier gain may be adjustable to preset the stabilised temperature. In modifications, (a) thermistors having temperature coefficients of opposite sign form adjacent bridge arms; the two other resistances being constant ; (b) all four resistances are thermistor heaters, each pair forming opposite arms preferably having temperature coefficients of opposite sign to the other pair. The thermistors may be of sheet material surrounding the space to be heated. Mathematical analysis with typical values is given. Specifications 510,379, [Group XL], and 545,679, [Group XXXVI], are referred to.
