Patent GB-150827-A (GB)
Title: Improvements in or relating to wheels for agricultural tractors and other vehicles
IPC: B60B15/10
Filed: 1919-06-11
Abstract: 150,827. Freeman, J. June 11, 1919. Slipping-preventing attachments to wheels. - Relates to slipping-preventing attachments for vehicle wheels of the kind comprising a series of spuds which are adapted to be projected from or withdrawn into the rim of the wheel simultaneously, and consists in the construction and arrangement of the parts whereby the power of the engine may be utilized to actuate the speeds. In one construction, Fig. 1, the wheel boss 6, carrying the spokes 7 and rim 8 rides loosely on a boss 1 either fast to a live axle 3 or driven by the sprocket 2. Limited relative rotary movement of the bosses 1, 6 is allowed by projections on the inner end of the latter engaging larger recesses on the former, the parts being locked in any adjusted position by pins 16. The boss 1 has pivoted to it by pins 13, the inner ends of the spuds 9, which are adjusted bv first removing the locking-pins 16 and driving the boss 1 and again locking the parts in the required position. In a modification, Fig. 7, the spuds 9 are pivoted to a disk 2 keyed to the axle, and the locking-pins 16 are carried by a member 25 which is adapted to be operated by hand or power through the medium of suitable connexions under the control of the driver. Fig. 9 shows a further modification in which the spuds 10 are of angular shape and pivoted to the rim at 28 being actuated by the rods 9.

Title: Improvements in magneto electric machines
IPC: H02K21/38
Filed: 1919-06-11
Abstract: 141,555. Olivetti, C. June 11, 1919. Inductor machines.-A magneto for igniting in internal-combustion engines and of the type comprising stationary magnets, a stationary armature, and a rotating inductor is constructed to give six flux-reversals through the armature for each revolution of the inductor; six or fewer hightension E.M.F. impulses and at equal or unequal intervals may be taken off the magneto according to the number of notches or projections of the interrupter cam. The pole-ends of one or more magnets 9, Figs. 1 and 2, rest upon soft iron polepieces 10, 11 through which are passed the bosses 26, 27 of rotating segments 5, 5<1> forming poleextensions of the magnets. The segments 5, 5' are supported by a non-magnetic cylinder 20 which also carries two other circular magnetic segments 4, 4<1>, this assemblage of parts constituting the inductor. The armature core 1 with primary and secondary windings 24, 25 is arranged at right-angles to the permanent magnets. The pole-pieces 10, 11 are connected together by a non-magnetic sleeve 23, in which there are fitted four magnetic segments 2,2<1>,3,3<1>, the segments 3, 3<1> being in contact with ends 6, 7 of the armature core. The angles between the six maxima of electro-motive force depend upon the angles subtended by the segments 2, 2<1>, 3, 3', 4, 4<1>, 5, 5<1>, and by suitably dimensioning these there may be obtained in the coils 24, 25 six E.M.F. impulses separated by 60 degrees, or, with the proportions shown in Fig. 1, four maxima spaced apart by 90 degrees with two intermediate maxima spaced from the others by 30 degrees. Magnetos may be designed with maxima occurring at unequal angular intervals for the ignition in V-engines. The plate 28 supporting the inter. rupter contacts 33, 34, Fig. 14, is fixed to an extension 14 of the pole-piece 11 so that the time of sparking may he adjusted by rocking together the plate 28 and the cylinder 23. The rotating cam 32 for actuating the interrupter lever 31 may have either grooves or projections. Figs. 14 and 16 are examples of cams with grooves 37 and proj.ections 36 for giving six and four sparks respectively per revolution. The segments 3, 3<1> may be omitted, Fig. 7. A magneto, according to the invention, may be converted into one of the ordinary type giving two flux-reversals per revolution by turning the stationary segments into the position shown in Fig. 8.
Patent GB-457115-A (GB)
Title: Method of and apparatus for purifying air
IPC: F24F8/133
Filed: 1935-05-21
Abstract: 457,115. Washing air. CAL SUEIRO, C. DE, 25, Calle de Hermosilla, Madrid. May 21, 1935, No. 14801. Convention date, May 29, 1934. [Class 55 (ii)] Vitiated air is passed through a body of water in a closed vessel by the suction produced by discharge of the water therefrom. The air is also washed by a spray or jet of incoming water, the supply of which may be continuous and the discharge intermittent through a siphon. Water from a main pipe 1 is supplied through pipes 6, 7 to an upper chamber A and through a pipe 4 to a lower chamber B which may also receive the discharge from chamber A. Pipe 6 supplies a perforated grid providing a rain and pipe 7 provides a jet. Vitiated air enters the upper chamber through inlets 18, 19 of piping 14 with depending ducts having orifices at their lower ends. Chamber B receives water jets from pipe 4 and a branch pipe 28 of a siphon overflow 22 from the chamber A. Water also falls as rain from short ducts supplied from a branch 24. Vitiated air enters chamber B through orificed pipes 31, 32 and water is discharged through a siphon 34<1>. With a continuous water supply the discharge through the siphons occurs automatically at intervals. In an independent operation of chamber A, the supply pipes to chamber B are closed and water rises in chamber A until siphon 22 effects a partial discharge through a pipe 27 to the main drain, causing air to enter inlets 18, 19 and ascend through the water as the level sinks to the siphon mouth. Further washing by incoming water occurs as the water level again rises, air being expelled through an outlet 17 which is then opened. If this outlet is insufficient some air is driven out through the orificed inlet pipes. Chamber B functions either independently of or together with chamber A in the same way.

Abstract: 354,789. Superposed telegraphy and telephony; two-way terminal equipment. STANDARD TELEPHONES & CABLES, Ltd., SKILLMAN, T. S., and ROCHE, A. H., Columbia House, Aldwych, London. May 14, 1930, No. 14812. [Class 40 (iv).] Telegraph and telephone signals are relayed between a submarine cable and a land line A, B so that in the submarine cable the telegraph signals occupy a frequency band below the telephone signals, and in the land line the telegraph signals are modulated to occupy a frequency band above the telephone signals. The telegraph and telephone signals from the submarine cable are separated by filters F2, F1 respectively, the telegraph signals modulate a carrier frequency from an oscillator 2, and the signals are recombined for transmission over the land line B. In the reverse direction the telegraph signals from the land line A are demodulated by a detector M1 before passing to the submarine cable. Part of the telephone currents received from the submarine cable are tapped from amplifiers A4, A5 to a detector amplifier DA2, which disconnects the apparatus controlling the transmission of telephone signals to the submarine cable. Part of telephone currents from the land line A pass to a detector amplifier DA1 bridged across an amplifier A2 to connect the cable to the telephone transmitter.

Title: Method and apparatus for the production of parachute shroud lines
IPC: B64D17/00
Filed: 1925-06-11
Abstract: 252,095. Irvin, L. L. June 11, 1925. Parachutes.-For producing a complete set of shroud lines of uniform length for a parachute, a length of cord. sufficient for a complete set is wound in zig-zag form over fixed rollers 35 on a baseboard 36 and over rollers 60 carried by a movable bar 55. The bar 55 is connected by cords 72 to a cable 65 on a winch roller 66 on the base board to enable the desired tension to be given to the cord, and while still under tension the loops are marked at each roller 60 where they are subsequently cut after dipping the loops in wax to prevent fraying. Holes 91, 96, 99 in the base board take pegs to act as stops for a straight edge 92 for enabling the lines also to be marked in predetermined positions to facilitate their subsequent arrangement upon the parachute cover and aviator's harness. An instrument 70 in the winch cable indicates the tension given to the cord, and a ratchet 75 and a pawl 76 enables the winch to be locked with the cord at the required tension. The two ends of the cord are secured in slotted pins 56 on the bar 55. After cutting, each shroud line is secured at both ends to the aviator's harness and passes diametrically over the cover and across the vent hole, the marks previously made ensuring that it is stitched correctly in position. A reel 80 at the side of the baseboard holds the cord initially.
