Title: Improvements in and relating to the liquid treatment of fibrous material
Inventor: BRANTON HAROLD
IPC: D01D10/04
Filed: 1955-06-30
Abstract: Apparatus for washing and dyeing fibres comprises a bath 6, Figs. 3-6, and a trough 2 having a perforated bottom 3 and which may swing on links 8 from the Fig. 3 position to the Fig. 4 position and back again.  The fibres 1 are fed from a shoot 4 into the trough to form a layer on the bottom 3.  When the trough swings into <PICT:0816674/IV (c)/1> <PICT:0816674/IV (c)/2> <PICT:0816674/IV (c)/3> <PICT:0816674/IV (c)/4> <PICT:0816674/IV (c)/5> the Fig. 4 position the fibres float on the top of the treatment liquid and are pushed to the left by the right-angled end of the trough.  On the return swing the trough moves beneath and relatively to the fibres 1 until they are lifted from the bath and drained, thus the fibres are advanced along the trough in step by step motion.  Liquid sprays may be provided above the trough, and a platen may be fixed above the ramp 12 to squeeze the fibres on the upward movement of the tray 2.  In the drawing accompanying the Complete Specification the trough 2 has a saw-toothed perforated bottom and is provided with a transverse hump 29 positioned over a division in the bath.  The trough is rotated about a point in space by links 20 and cranks 21 rotated by a driving shaft 22, and the fibres are lifted over the hump 29 by a rotatable drum 31 having flexible strips 311.  The bath is divided into at least two compartments and the liquid levels therein are maintained constant by inlet pipes 34, 35 and stand pipes 36, 37.  In other modifications the trough 2 may be driven so that it describes a rectangle, or it may be reciprocated in a horizontal line and means provided by which the level of the liquid may be raised and lowered. In a further modification the trough 2 is swung back and forth symmetrically about the position where the arms 8 are vertical so that the fibres move forwardly and backwardly.  In yet another modification, Fig. 7 (not shown), the bath is divided into compartments for different liquids by means of rubber divisions which are attached to the sides and bottom of the trough 2 and the bath 6, and the trough is divided into separate compartments by wedge-shaped transverse divisions over which the fibres climb during the rearward movement of the trough.

IPC: H01Q19/19
Filed: 1971-06-08
Abstract: 1342677 Aerials COMMUNICATIONS SATELLITE CORP 8 June 1971 [8 June 1970] 19448/71 Heading H4A An aerial having a toroidal reflector, the surface of which is described by the rotation of a generating curve about an axis, and which forms a beam when illuminated by a feed means, is characterized by the angle between the said axis of rotation and the axis of the beam being greater than 90 degrees. Said feed means is symmetrically deployable about said axis of rotation, for scanning. As shown in Fig. 3, a generating curve M, which is taken as a parabola with a focus F and an axis Z, is rotated about an axis R which is at an angle α greater than 90 degrees to the said axis Z. The position of the curve M after 180 degrees of rotation is indicated at M<SP>1</SP>. When the reflector surface is illuminated by a source H near the focus F a beam is formed having an axis PA parallel to the axis Z and at an angle α to the axis R. As the feed means is rotated around the axis R, the beam axis PA describes a conical surface. The invention may be applied to an earth station which is located away from the equatorial or orbital plane and which must communicate with more than one satellite positioned along the geostationary arc. For this, scanning along a conical surface is required (Fig. 1, not shown). A plurality of feed means (one for each satellite) may be provided along the focal or feed arc of a toroidal reflector of the kind described. In another embodiment, an intermediate reflecting surface is provided between a feed means and a main toroidal type reflector (Fig. 4, not shown).

Title: Improvements in or relating to electronic switching circuits
IPC: H03K17/54
Filed: 1959-06-08
Abstract: 848,497. Valve switching circuits. FERNSEH G.m.b.H. June 8, 1959 [June 6, 1958], No. 19518/59. Class 40(6). In an electronic switching circuit, Fig. 1, the individual signal paths 1, 2 each contain two sets of diodes (9, 10 or 17, 18) connected in series in the path and a capacitor 11 or 19 shunting the signal path at the junction of the diodes. The signals are fed to the switches through cathode followers 5, 13 and the diodes in each switch are oppositely poled so that one or other of the paths may be made conductive by connecting either a positive or a negative bias to the junction of the two paths by a switch 34. In practice the switch and bias potentials may be replaced by a suitable bi-stable switching circuit. The output selected is fed on to the grid of a valve 3, to which is also connected a clamp circuit to avoid switching transients in the output. In a second embodiment (Fig. 2, not shown) switching circuits as described above are used to select a signal from, say, channels I and II and another from channels III and IV. These two signals are then applied to a further similar circuit which again operates to select only one of the signals. In a further embodiment (Fig. 3, not shown) three inputs are connected to a common output terminal by switching circuits all having their diodes similarly poled. Switching potentials may be applied to the circuits to select any one of the signals, or alternatively signals may be combined by selecting two together.

Abstract: 731,127. Thermionic distributers. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 14, 1953 [July 18, 1952], No. 19576/53. Class 40 (3). The electron beam in a discharge tube of the type known as a binary trochotron and described in Specification 675,465 is directed in a sequence to the contact electrodes 6-13 by applying harmonically related voltage waves as shown in Figs. 2a-2c to the control electrodes 14-20 which are connected in groups and brought out to terminals 21-23. The rail 5 is operated at zero potential and the anode 4 supplied with a, positive potential. The amplitudes of the voltage waves and the biases of the groups of control electrodes are chosen so that the electrodes vary in potential between that of the rail and that of the anode. If the waves in Figs. 2a, 2b and 2c are applied to terminals 21, 22 and 23 respectively, the beam is directed to the contact electrodes in the sequence 13, 12, 11, 10, &c. By supplying the waves to the terminals in another order the beam is directed to the contact electrodes in another sequence. The sequence may also be altered by shifting the phase relationship of the waves. Each wave must, however, have a zero value at a time when the wave of the highest frequency has a zero value. Impulses, such as 24-31 in Fig. 2d, unmodulated or modulated in amplitude duration or position may be applied with appropriate polarity to the control grid 3, cathode 2 or anode 5 for distribution to the contact electrodes. The voltage waves applied to the control electrodes may be sine waves.

Filed: 1945-08-02
Abstract: 599,838. Pipe couplings and piperepairing means. WURZBURGER, P. D. Aug. 2, 1945, No. 19927. Convention date, Sept. 27,1944. [Classes 99 (i) and 99 (ii)] A pipe coupling is of the type described in Specifications 403,870, 491,761, 492,336, 527,999 and 528,306, but is distinguished in that the coupling member (6 on the drawings) is slidable on the pipe and also in that it has an outwardly flared mouth (8) at each end. Such an arrangement enables the coupling to be used in a method of repairing a pipe which has been damaged such as by a bullet hole, the method comprising severing the pipe completely through the damaged portion and re-uniting by means of the coupling. The coupling consists of a coupling member 6, sealing rings 9 and coupling nuts 12, the rings and being compressed into the flared ends of the member 6 and into " biting " engagement (Fig. 5) with the pipes on tightening the nuts 12. The pipe ends normally abut inside the coupling member, but they can be spaced apart if relative axial movement is prevented by connecting them to fixed points by means of additional couplings. Fig. 2 shows a pipe 1 damaged at 2, and severed completely at 3, the severing being the first step in the repair. Fig. 3 shows the two parts 4, 5 of the pipe moved relatively into such a position that parts of the coupling can be slid on each pipe part as shown. The parts 4, 5 are then brought together again, the coupling member 6 slid over the damaged portion, and the coupling completed as shown in Fig. 5, there being now a fluid-tight seal on each side of the hole 2.
