Title: Improvements in or relating to shedding mechanisms for looms
IPC: D03C5/06
Filed: 1960-10-03
Abstract: 937,903. Shedding mechanism for looms. W. E. N. LAURITSEN. Oct. 3, 1960 [Oct. 6, 1959], No. 33882/60. Class 142 (2). The individual healds 1 have magnets or soft iron armatures 3 at each end which are attracted by magnets 5, 6 common to all the healds. In one embodiment, permanent magnets 5, 6 are used which are moved apart (from the positions shown in broken line) to effect shedding. The magnet 6 and an associated comber board 10 start to move first, any healds that are not required to descend being pushed off the magnet 6 by plungers 7 operated by fluid pressure under the control of pattern mechanism; these healds remain in contact with the magnet 5 and associated comber board 11 and rise with them. In another embodiment, fixed electromagnets are employed; in this case, the magnet 6 is stronger than the magnet 5 so that any healds that are not disengaged from it by plungers 7 are drawn down when the comber boards 10, 11 approach each other, the other healds being drawn up by the magnet 5.

The container 1 is carried by the members 3 by means of hems 2, and is secured to the members 4, 5 by pressstud fasteners 17 on opposite sides of a recessed portion 18. The ends of the members 4, 5 may be fitted with tubular handles 19 having rubber or plastic outer sleeves 20, Fig. 7, and flanges 21 to abut the walls of the normal bath. For length adjustment, each tube 19 may be embraced by a split spring collar 22 carrying a pin 23 to engage any one of a series of holes 24 in the associated part 4 or 5. As an alternative to the flanges 21, the members 4, 5 may be cranked upwardly.

Steps (1) and (2) may be carried out together or in either order.  If no hydro-silanes are present, step (1) is omitted.  The organic groups may be alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl, alkaryl and their halogenated derivatives.  Examples of substances which yield oxidizing agents in situ are chromic oxide, potassium dichromate, manganese heptoxide and potassium permanganate. In step (2), the phosphoric acid preferentially esterifies the tri- and tetra-chlorosilanes.  Preferably the mixtures contain less than 0,2 mol. per cent of these chlorosilanes and less than 0,5 mol. per cent of silicon-bonded hydrogen.  The diorganodichlorosilanes are hydrolyzed and condensed to high molecular linear gums.  Examples are given.

The PAL chrominance signal is supplied via band-pass amplifiers 12, 14 to a oneline delay circuit 17, an adder 15 and a subtractor 16. The output of adder 15 is supplied to a B-Y demodulator 21 and the output of subtractor 16 is supplied to an R-Y demodulator 26a via an inverter 24 and PAL-switch 23 operated, during reception of a colour signal, at the end of each line period. The output of band-pass amplifier 12 is fed to a burst gate 31 which supplies a colour killer circuit 39, a subcarrier oscillator 33 and a synchronous detector 32 which supplies a pulse signal to resonance circuit 34 the output of which is fed to a waveform shaping circuit 35 which controls the phase of a flip-flop 26 which also receives line synchronizing pulses at terminal 25 and controls PAL-switch 23. In one embodiment (Fig. 6, not shown) the line synchronizing pulses are supplied to the emitter of a transistor (44) included in shaping circuit 35, the base of the transistor receiving the output of the resonance circuit 34, so that this transistor is conductive, producing an output of circuit 35, only when a line synchronizing pulse coincides with the positive peak portion of the output of resonance circuit 34. In a second embodiment (Fig. 7, not shown) the colour killer signal from circuit 39 is also supplied to resonance circuit 34 to disable its operation during monochrome reception.
