Title: Improvements in self laying tracks for road vehicles
IPC: B62D55/24
Filed: 1925-11-25
Abstract: 266,795. Ross, T. B. Nov. 25, 1925. Endless-track vehicles.-An endless-track of resilient material, such as canvas, rubber, fabric or the like, is displaced during its motion from a position in a longitudinal vertical plane into a position substantially parallel to the ground. The track comprises an endless band 6 having separate fingers or ribs 7 integrally connected at one or both ends, and passes over idle pulleys 1, 2, the axles of which carry guides 11, 12 for the track. The top run of the track lies in a vertical plane and as it passes over one of the guides the fingers 7 are bent over until at the bottom of the pulley they lie in a horizontal plane and are transverse of the vehicle. The guide at the other end of the track gradually allows the fingers to take a vertical position again. The driving wheel 5 thus runs on the horizontal portion of the track, and the vertically-disposed upper run of the track passes at the side of the driving wheel. One of the pulleys 1, 2, may be driven. The fingers 7 may be reinforced internally or externally by leaf springs. According to the Provisional Specificataion the band may be a metal one.

Abstract: 1,236,198. Automatic phase control. NIPPON ELECTRIC CO. Ltd. 12 June, 1969 [12 June, 1968]. No. 29917/69. Heading H3A. A circuit for synchronizing the phase of a voltage-controlled oscillator 11 with an input signal 1 modulated in n phases comprises: n phase comparators 2, 3 arranged to compare the input signal with components of the oscillator signal which are phase displaced by #/n; n circuits 6, 7 for converting the comparator outputs to rectangular pulses; and an n-input EXCLUSIVE-OR or PARITY circuit 9 for producing an error signal for controlling the phase of the oscillator 11. As described, the input signal is modulated to either 0 or # and is fed to the two phase detectors 2, 3 together with quadrature components of the signal from oscillator 11. The polarities of the outputs of the two detectors are determined by circuits 6, 7 to provide two level input signals for the EXCLUSIVE-OR 9. The resulting output signal is independent of which of the two phases is held by the input signal. The detector output may be sampled by a high-frequency clock 4, 5, 8.

Filed: 1938-10-19
Abstract: 519,485. Upward-current classifiers. KENNEDY, J. E. Oct. 19, 1938, No. 30237. [Class 82 (ii)] In an upward-current classifier, material to be classified is fed through a hopper 16, over a deflecting-plate 17, into a container 8 which hangs from eye-bolts 10 having thereon abutments 15 supported on springs 13 mounted on fixed beams 12 through holes in which the eyebolts 10 pass. In the open bottom 21 of the container is a closure member 20 mounted on links 24 pivoted on the fixed beams and connected by links 25 to crossbars 26 in the top of the container, so that upward movement of the container raises the member 20 to close the mouth 21 while downward motion of the container lowers the member 20 to open the mouth 21. Liquid is supplied to the container by a pipe 31 and a series of pipes 28 which open into the container tangentially, so as to produce a swirling effect with the liquid and carry the lighter particles of the material in the container over a discharge launder 34. The heavier material is discharged through the mouth 21, the amount of opening thereof being proportionate to the weight of material in the container. The amount of opening of the mouth 21 for a given weight of material in the container is controlled by adjusting the abutments 15, and the normal adjustment permits of a discharge of heavy material corresponding to the amount of unclassified material being fed into the container. An arm 36 and a link 38 enable the mouth 21 to be opened manually when desired.

Title: Rope splice and method of making the same
IPC: F16G11/00
Filed: 1945-11-12
Abstract: 602,948. Splicing ropes &c. NEWTON, E. P. (American Chain & Cable Co., Inc.). Nov. 12, 1945, No. 30237. [Class 109] Two rope sections are connected together by arranging the separate strands of one rope section helically around the other rope section in the valleys between the strands thereof and binding the separate strands to the body of the rope section. The splices may be made in the making of eyes, between the ends of ropes, and in the attachment of a rope to an intermediate part of another rope. In the formation of an eye, the unlaid end strands of a rope, comprising strands 11 laid about a core 12, are wound about the standing part of the rope so as to lie within the valleys between the adjacent strands thereof, the core being cut off at 13. The strands are then secured in place, such as by applying a clamping member around at least part of the helically wrapped portion. A single long ferrule may be used or, as shown, a pair of ferrules 14, 15, Fig. 6. The ferrules are secured in place by swaging or simple pressing, and are preferably separated a distance sufficient to permit of a snubbing action of the strands around the laid sections. In a modified method of making an eye, half of the strands 21A, Fig. 9, are unlaid from the core and the unlaid end strands 21B of the remainder are helically disposed about the standing part of the rope to form the eye, the core being cut at 23. The strands 21A are then relaid about the core and strands 21B, starting at the unstranded end, forming the eye. The ends of strands 21A are finally unlaid and helically wrapped about the standing part. The splice is then completed with one or more ferrules as before. The unlaid strands may be inserted under the strands of the standing part of the rope directly around the core, the strands of the standing part lying in the valleys of the rope laid within it.

[Classes 20(ii) and 20(iv)] An arched roof is formed by adjoining in bond pre-cast concave slabs e.g. of light concrete, having grooves A along all abutting edges and an extra thickness B on the underside of the longitudinal edges which is bevelled at P so as to form dovetailed projections when two slabs are placed together. The slabs are connected by flat steel bars C inserted in the grooves A and by clips D driven on to the dovetail projections and the latter also have similarly shaped suspension clips (not shown) bolted across them fastened to rods supporting tie-rods K. As shown in Fig. 2, these rods are connected to folded iron tie straps J which are hooked to an angle-iron pole plate G, and which may bear against the wall and be bent back for this purpose as at L. The angle-iron G supports the eaves slabs F provided with a bevelled transverse extra thickness to engage with same, and alternate eaves slabs may be half-length to provide the bond between the slabs. As shown in Fig. 1, each clip D may comprise a flat iron bar riveted at each end to an angle iron E, which is driven into the bevelling and given a cement backing. The slabs may be grouted together, or a weatherproofing material may be applied to the joints and exposed parts of the finished roof.

Abstract: 870,401. Arc-rupturing in switches. REYROLLE & CO. Ltd., A. Dec. 22, 1959 [Sept. 26, 1958; March 5, 1959], Nos. 30893/58 and 7760/59. Class 38 (5). In an arc shoot comprising a stack of slotted spaced insulating plates 10 arranged transversely to the direction in which the arc is initially drawn, a portion of one or each of the two legs of each plate which extend on either side of the slot 11 in the plate is thicker than the portion of the plate extending around the closed end of the slot. Figs. 1 and 4 show an arrangement in which one leg 27 of each plate has insulating blocks 30 secured on each side of the leg. The successive plates are alternately disposed so that in the assembled stack only a small gap 35 exists between each block 30 on a leg 27 and the adjacent leg 28. These gaps are too small for downstriking of the arc to occur between adjacent legs but sufficient to prevent tracking occurring along the tunnel formed by the slots 11. The upper part of the slots 11 may diverge as shown in Fig. 1 and the plates 10 may have magnetic inserts 19 to provide a blow-out action. Figs. 5 and 6 (not shown) illustrate an arrangement in which the slots are straight and the blow-out action is provided by a blow-out coil.
