IPC: B43K5/17
Abstract: 1,095,389. Retractable fountain-pens. PILOT MAN - NEN - HITSU KABUSHIKI KAISHA. June 30, 1966 [Feb. 25, 1966], No. 29506/66. Heading B6P. A retractable fountain-pen has an apertured end part 2 constituting the front end of the barrel 1 which has an inclined, flat front surface 4 bordering the aperture. A closure plate 9 (Fig. 7) with side trunnions 12 is rotatably mounted in the aperture to swing flat against the flat front surface. A spring device (Figs. 8 and 9) comprising a core member 13 fitted in recesses across the aperture, a spring wire wound around the core member, the ends of which are anchored to the core member, and an intermediate part 19 of the spring wire formed into a lever, exerts a spring force on the closure plate to maintain it in contact with the inclined front surface when the pen nib is retracted. In a modification (Figs. 13 to 16) the spring device is made of spring wire and consists of a fixed part (76) rigidly fixed to the pen barrel, leg parts (78) extending longitudinally forward from the fixed part, and a transverse part (79) spanning the front extremities of the leg parts which in so doing extends across the front of the closure plate to urge the same into contact with the flat front surface surrounding the aperture. To project the pen-nib into the writing position, a plunger 54 is moved forwardly relative to the pen's outer casing 24, Fig. 1. This results in a circlip 49 passing through the restricted end 28 of a guide cylinder 27, whereafter it is permitted to expand in an annular gap 38 to retain the pen-nib in the advanced position against the bias of a spring 63. To retract the pen-nib, the plunger 54 is again moved forwardly, whereupon the circlip 49 is compressed into a shift ring 35 (Fig. 11). The plunger 54 is then released whereupon the circlip 49 and shift ring 35 move rearwardly until the shift ring strikes the front end of the guide cylinder 27 (Fig. 12). Thereafter, the compressed circlip 49 enters the guide cylinder 27 to the fully retracted position. Cartridge reservoirs 59 are used to supply ink to the pennib, and a spare cartridge 59a is housed rearwardly of the cartridge in use, within the plunger housing 54.

Abstract: 1,226,195. Continuous sampling of slurry. OUTOKUMPU OY. 11 Nov., 1968 [17 April, 1968], No. 53310/68. Heading B1X. [Also in Division B8] A sampling apparatus similar to that described in Specification 1,226,196 includes a well 15 which communicates with a discharge orifice 18 via a riser pipe 16, a through-flow cell 10 having a window 11 therein, and a pipe 17. The through flow cell is associated with an analyser e.g. an on-line X-ray fluorescence analyser. The level of liquid Ho in the feed pipe 5 is maintained constant by means of a sensor 6 sensitive to hydrostatic pressures which, via a control unit 7, causes actuation of device 9 for adjusting a flap 8 so as to control the amount of liquid diverted into the pipe 5. Initial application of suction to outlet pipe 17 starts a syphoning action so as to draw liquid from the pipe 5 via the cell 10. In the apparatus illustrated the window 11 is above the liquid level Ho. In an alternative embodiment the window 11 may be at the level Ho of the liquid.

Abstract: 1,252,305. Automatic exchange systems. SIEMENS A.G. 25 Aug., 1969 [26 Aug., 1968], No. 42202/69. Heading H4K. In a system utilizing a remanent relay switching network in which relays are normally released at the end of each call, the possibility of double connections, arising from the false closure of crosspoints caused for example by failure to release of a relay used on a preceding call, is prevented by connecting a test device to each path after it has been switched through but before ringing etc. has taken place whereby if a false potential is present on the path it is broken down and a new path is set-up. The test device comprises a series pair of NPN and PNP transistors connected to each speech wire where these enter the supervisory junctor (Fig. 2, not shown). The two speech wires in the network should not carry any potential when free and should carry respectively earth and negative battery when in use (i.e. after testing). Therefore if any potential whether positive, negative or earth relative to a reference potential of e.g. + 6 volts is detected, a fault is indicated and the path is released. If a same part of a plurality of selected paths repeatedly causes the test device to respond, an alarm is initiated and a print-out of the faulty part is provided. In order to prevent subscribers line voltages from affecting the test, the crosspoints in the primary switch are not operated until the rest of the path has been tested. Alternatively a relay in the line circuit may temporarily hold-off the line wires from the primary switch during initial cut-through and testing.

Abstract: 1,264,869. Automatic frequency control. GENERAL ELECTRIC CO. 2 July, 1969 [2 July, 1968], No. 33347/69. Heading H3A. [Also in Division H2] The speed of one or more electric motors energized from inverters is controlled by varying the frequency of respective local oscillators controlling the inverters in response to the difference between their input and the selectively divided output of a single master oscillator. (Fig. 1, not shown, see Division H2). Comparison is made in discriminators which may operate as an integrating circuit and comprise three flip-flops for indicating respectively that the speed is too high, correct, or too low. When the master pulses exceed the rate of the feedback pulses, the frequency of the latter is increased at a rate determined by the constantcurrent charging of a capacitor controlled by a transistor, Fig. 5. A stabilizing circuit is added to the distributer to bring the slave pulse train quickly into proper phase relationship with the master train when synchronization is approached. A stabilizing voltage pulse is placed in series with the steady state reference voltage, which is developed across the capacitor, to change the slave pulse rate transiently. The capacitor is adapted to be charged or discharged at constant current. When the charge and discharge rates are equal, the stable phase relationship is achieved with the slave pulses occurring midway between the master pulses. In another arrangement there is no integrator at the output of the discriminator. When higher speeds are called for the higher capacitor voltage requires charging for longer periods during each cycle so that the discriminator delivers a long pulse followed by a short gap for each master and slave pulse received, Fig. 7. In this arrangement, the stabilizing means shifts the slave pulses to a position relative to the master pulses in accordance with the repetition rate of the pulses.

A few further run-stop courses 14 are knitted of which one or more is knitted of a thermoplastic yarn which fuses in a later processing stage, e.g. dyeing to prevent unravelling. The blanks are either simultaneously cut and seamed together or else are cut, e.g. by hand prior to seaming on an overlock machine. The blanks may be cut and seamed at 17a to improve the shape and fit of the garment. The blanks are preferably knitted throughout of a stretch yarn and may have a patterned micro-mesh structure.

The torque may be applied to the roller 30 by an hydraulic motor or by a brake. In other embodiments a plurality of lengths of tubing may be coiled to produce multi-start coils or the tubing may be finned.
