Abstract: 233,063. Blackburn & Sons, Ltd., G., and Widdowson, T. Feb. 7, 1924. Circular machines. -The patterning attachment described in Specification 192,222 is modified in that the radial movements of the dependent thread guides A are obtained from a single rising and falling cam C, and only those guides actually required for patterning are moved outwards bv it. To increase the number of effects which can be produced, the projections B are made of different dimensions or are situated at different levels. The upper ends of the guides A are secured to a head D on an angularly adjustable cylindrical casing E. The cam C is fixed by screws C<2> to splines L slidable along a rotary sleeve F passing through the casing E. A fork engaging a collar N to which the upper ends of the splines L are secured enables the cam C to be raised or lowered while rotating. The instrument dial H is carried on a fixed shaft which passes through the sleeve F. The pattern wheels O, S, R, Fig. 5, for respectively producing interrupted stripes, angularly adjusting the part E and raising and lowering the cam C, are advanced by ratchet wheels W, T which are driven by a single pawl. Some of the teeth on the wheel W are shallow and some are deep enough to allow the pawl to engage the wheel T. The wheel O may thus be advanced faster than the wheels R, S when required. The wheels may be locked to the shaft Q by means of screws Q<1>.

Abstract: 936,149. Fluid actuation of switches. TEDDINGTON AIRCRAFT CONTROLS Ltd. April 26, 1961 [Jan. 29, 1960], No. 3297/60. Class 38 (5). [Also in Group XXXII] A method of damping externally-induced mechanical vibrations in elastically-constrained pressure sensing elements, e.g. actuating diaphragms in pressure switches, gauges, &c. comprises introducing into the sensing element chamber one or more pipes, or recesses, open and closed respectively at the end, or ends, nearer to, and further from, the element so that resonant vibrations can be spontaneously induced into the pipes, or recesses, to oppose the externally-excited vibrations of the sensing element. The length of a pipe, or recess, is either approximately one, or an odd number of, quarter-wave lengths of a vibration in the pressure medium corresponding to the lowest natural frequency of the diaphragm so that a pressure pulse fed into a pipe, or recess, is reflected back from the closed end in opposite phase to the oscillating pressure in the chamber. The open end of each pipe, or recess is set at an anti-node of pressure several pipes, or recesses, being necessary as the wavelength corresponding to a fixed frequency increases with temperature. As shown in Fig. 1, a nest of three pipes 4, 5, 6 each of different length and wound upon a three-start helix are located within an annular recess 3 in a holder 2 for a corrugated diaphragm 1 of a pressure switch the diaphragm having a contact 7 for co-operating with an adjustable contact 8 which is mounted in, and insulated from, a sealed container 9.
