Title: Improvements relating to terminal assemblies for telephone exchanges
IPC: H04Q1/04
Filed: 1927-10-12
Abstract: 301,163. Siemens Bros. & Co., Ltd., and Lambert, C. Oct. 12, 1927. Addition to 270,834. Automatic exchange selectors and associated apparatus.-In a distributing frame for commoning the mutiple cables from shelves of switches and connecting them to trunks leading to subsequent switches, the terminal strips for the wires incoming from switches are arranged vertically as in the parent Specification, while the terminal strips for 'the wires outgoing to switches are mounted at the back of the frame. It is thus possible to accommodate the multiple wires from a shelf of 200-point selectors on the strips in a single column, each strip accommodating the wires from one level. The incoming terminal strips 3 are carried by vertical bars 4 supported by transverse members 5 at a distance from the angle iron frame 1. Each bar 4 carries blocks 7, 8 with interposed insulating material 6, and the ends of the multiple cable from the selector shelves are brought through holes 9 for connection with the T-shaped terminals 10 described in the parent Specification, while the jumper wires from the terminals 10 to the outgoing terminal strips 11 are taken through holes in the blocks 8. The outgoing terminal strips 11 are mounted on vertically-spaced cross-members 12 opposite the corresponding incoming terminal strips 3, and the cables 14 therefrom are led over the members 5 to one end of the frame. Rings 15 are provided at one end of each frame for jumpering between levels for various purposes. A number of frames may be placed end to end to form a frame with a continuous grading field, the selector racks being disposed at right-angles thereto. If a rack contains only 6 instead of the full 12 shelves, the corresponding distributing frame is fitted with alternate columns of terminal strips only, in order to preserve the normal width of frame. When the spacing between the strips is increased, there is danger of contact between adjacent commoning wires, and to obviate this, twisted insulated wires 16 are employed. If the frames are localized instead of being continuous, the commoning wires are connected between them by tie cables, which may be connected to an additional column of terminal strips at one or both ends of the frames.

Title: Device for temporarily storing a weft
Inventor: MULLEKOM HUBERT PETER VAN
IPC: B65H51/20
Filed: 1969-05-28
Abstract: 1275076 Weft measuring and storing devices MACHINEFABRIEK L te STRAKE NV 28 May 1969 [28 May 1968] 27047/69 Heading DIE A weft measuring and storage device, with weft selection for use with a jet loom inserting hair pins from both sides of the shed, has a pair of travelling chains each with a weft hook spaced apart on different runs of the chains so that each hook draws the weft into a loop for one leg of the hairpin whilst the other leg is being picked. In Figure 1 three weft supply tubes 20 are rotatable so that a selected tube presents its weft 22 to the device through an outlet 21. The device includes a top plate 14 with pairs of grooves 18 for the weft loops, retractable adjustable weft catchers 26a, 26b and adjustable cam shifters 27a, 27b. Upper and lower weft clamps 16, 17 cooperate with an anvil 15 of the top plate 14 and the chains 5a, 5b have weft hooks 9a, 9b spaced 180‹ apart that are pivoted by cams 8a, 8b. In use, with reference to Figures 3 to 8 (not shown) weft 22 supplied by rollers 23 is fed to the supply tubes 20 and the supply tubes are rotated to bring a selected tube 20 to the position shown in Figure 2. The tubes then commence to move in a closed path indicated by the arrow 25 so that the weft end is placed between the anvil 15 and upper clamp 16 which closes on the anvil to grip the weft. Continued movement of the supply tubes 20 places the weft around a shoulder 19a of the top plate 14 and under the plate 14 until it reaches the position of Figure 5. The hooks 9a then engage the weft and draw it into a loop in the channels 18 until the loop is engaged by the weft catcher 26a and the shifter 27a pivots the cam 8a to release the loop from the hooks 9a. The position of the catches 26a and shirters 27a are adjustable to vary the length of the loops. The tubes 20 then move on until the bottom clamp 17 operates to clamp the weft against the anvil 15 and a needle 27a in the top plate 14 then moves to push the weft into a picking nozzle simultaneously with its release by the catcher 26a. The tubes then move so that in a similar manner a loop may be drawn by the second hooks 9b for the second leg of the hair pin whereupon selection is again made and the loops measured and picked.

IPC: F01D5/08
Filed: 1952-10-31
Abstract: 742,476. Turbines and compressors. ROLLS-ROYCE, Ltd. Oct. 23 1953 [Oct. 31, 1952], No. 27511/52. Class 110(3) In a bladed stator or rotor construction for axial-flow turbines or compressors, the attachment portions of the blades have shoulders which engage corresponding slots in a supporting structure, the attachment portions affording between them tunnels which extend in a generally axial direction. The blades have at least two passages therethrough, which passages communicate at the blade tip and extend through the attachment portion. The blades are arranged on the supporting structure so that one passage, the inlet passage, opens into the same tunnel as the inlet passage of the next adjacent blade on one side of it, and the other passage, the outlet passage, opens into the same tunnel as the next adjacent blade on the other side of it. Blanking meansare provided to close off at least the corresponding ends of alternate tunnels and the opposite ends of the remaining tunnels. In Fig. 1, the blade comprises a vane portion 11, a platform 12. a stem portion 14 and a shouldered root fixing portion 13. The vane portion has three passages therethrough, passages 17, 18 being at the leading and trailing edges and passage 19 midway between, the passages being connected at 22 at the blade tip. The inlet passages 17, 18 and the outlet passage 19 open at 17a, 18a and 19a on opposite sides of the blade stem 14. The blades are mounted in the thickened rim 10a of a rotor disc 10, alternate blades having the openings 17a, 18a and 19a on opposite sides of the stems. The tunnels 16, Fig. 6, into which the inlet passages 17, 18 open, 'are open at the upstream end and closed at the downstream end by blanking plates, while the tunnels 16 into which the passages 19 discharge are closed at the upstream end by blanking plates 24 and open at the downstream end. Cooling fluid such as air is supplied to the inlet passages 17, 18 through tunnels 16 and and discharges through passages 19 into alternate tunnels 16. In Fig. 9, the tunnels 16 connecting to the inlet passages 17, 18 are closed at both ends, and the tunnels 16 into which the passages 19 discharge are closed at the upstream ends only. Cooling air is supplied from the space 40 through the drillings 45 to the annular space 44 formed in the rotor disc and so to the tunnels 16 connected to the inlet passages. The tunnels 16 receiving the discharged cooling air are sealed off from the annular space 44 by blanking plates 46. Specifications 699,582 and 742,477 are referred to.

Patent GB-394697-A (GB)
Title: Improvements in or relating to wave filters
IPC: H03H7/01
Filed: 1931-10-03
Abstract: 394,697. Impedance networks. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 3, 1931, No. 27537. Convention date, Oct. 4, 1930. Addition to 364,561. [Class 40 (iii).] The parent Specification describes filters comprising oppositely - connected component filters having different band-widths but the same geometric mean of cut-off frequencies. The present Specification extends the theory to filters with wide transmission bands, and shows how to dimension them with respect to steepness and symmetry of the attenuation curves and flatness of the characteristic-impedance curve. In the simplest case the filter is composed of two components, one of which comprises the, branches C1L1, C4L4, and the other C2L2, C3L3, where the lower-frequency arm L4C4 of one component is grouped with the highestfrequency arm L2C2 of the other, so that the components are oppositely connected. The frequencies of the components are chosen by giving pairs of equal and opposite values to the quantity k where w = # exp (¢ kb), or # #(1 + kb), or # # (1 - kb), or some similar function which = when x = o, # being the frequency of an arm, # a constant ("transmission-band centre") for the whole filter, and b another constant ("relative band-width"). The steepness of the attenuation curve is regulated by choice of the ks. The degree of symmetry of the attenuation characteristic is regulated (e.g. for matching a line having an asymmetrical characteristic) by a parameter which depends not on the #s but on the inductance-ratios and capacity-ratios of the two branches having the highest and lowest frequencies ; thus with the first formula given above, gamma<4> = L1C4/L4C1. Fig. 1 relates to this case and shows attenuation (nepers) against frequency plotted as #/#. Curves 1, 2 are symmetrical, with gamma equal to 1, but curve 3 is asymmetrical, with y equal to 1À034. Curve 2, for which k = 0À56, gives a steeper cut-off than curve 1, for which k = 0À5. When there are more than two component filters there is still a single y determined by inductance-ratios and/or capacity ratios of the two extreme arms, but there are (m - 1) different parameters k1, k2, .. , corresponding to the various resonances, when there. are m component filters or 2m arms. The characteristic impedance is rendered uniform within the transmission band by adding a component filter, such as COLO, C5L5, Fig. 2, having impedance proportional to and wave range the same as those of the extreme component, C1L1, C1L4, but is oppositely connected. The flatness of the impedance curve then depends, in the manner shown in Fig. 3, upon a further parameter n, which is a function of k, y, (#4 = #1) and L1/L0. Several quantitative examples are given in the Specification.
