Title: Improvements in devices for raising and lowering the working parts of cultivators, ploughs and like agricultural implements
IPC: A01B63/16
Filed: 1922-07-26
Abstract: 205,890. Lowson, J., Challacombe, A., and Ruston & Hornsby, Ltd. July 26, 1922. Multiple-furrow ploughs; lifting- devices, power.-In an implement mounted on cranked axles, the frame is held in raised or lowered position by means of a pawl or catch on an arm or extension on one of the axles, and is lowered by gravity on the pawl being moved by a pull on a cord, and raised by locking the axle to the travelling wheel by a further pull on the cord. The spring-controlled pawl d on the arm c on the cranked land-wheel axle moves over a guide quadrant f and engages in a notch g and a recessed adjustable stop h to hold the plough in raised and lowered position respectively. The quadrant f is curved about the upper spindle a of the cranked axle. A bell-crank lever i on the arm c is linked to a spring-controlled lever m carried by a bracket on the cranked part of the axle. The operating cord or rope j is fastened to the lever i after passing round pulleys on the pawl d and spindle a. In the raised position a roller on the lever i bears against a cam z on the guide quadrant f. On pulling the rope, the pawl d is released from the notch g and the frame falls until the pawl enters the recessed stop h. On pulling the rope again, the pawl d being prevented from swinging, a tooth or pawl o on the lever m is brought into engagement with a ratchet wheel p on the land wheel and the frame is raised until the pawl d enters the notch g and the roller y engages the cam z and disengages the tooth o from the wheel p. The arm c is adjustably connected by a screwed spindle to an arm t on the furrowwheel axle. In tractor ploughs, the arm c is connected by a chain or rod u to a bell-crank lever v provided with a roller engaging the vertical spindle of the rear wheel x, so that the rear part of the plough may be raised simultaneously with the front part.

Title: Cast iron
IPC: C21C1/10
Filed: 1952-08-14
Abstract: Spheroidal graphite cast iron is produced by desulphurizing an iron melt with cerium, treating a first portion, amounting to 30-70 per cent with 0.05 to 0.15 per cent magnesium, deslagging, and recombining the two portions after the second portion has been heated to a temperature such that the whole melt is at the proper casting temperature.  A slight excess of cerium may be added during the desulphurizing to leave some cerium in the melt.  The magnesium may be added as the element, as an alloy, e.g. with Ni, Cu, Al, or Si, or as a compound, e.g. carbide, nitride, hydride or chloride.  The carbon content of the metal may be between 3 per cent and 4 per cent while the silicon content may be increased to 1.3 per cent to 2.5 per cent in the final melt either by addition to the second portion or to the melt before treating the first portion with magnesium.

Title: Manufacture of rayon
IPC: B65H54/80
Filed: 1943-12-15
Abstract: <PICT:0576486/IV/1> <PICT:0576486/IV/2> Freshly spun rayon thread, e.g. from viscose, is withdrawn from the coagulating bath and directed into a receptacle rotating about its own axis, the receptacle also being concurrently rotated about an axis spaced from that of itself, whereby the thread is deposited in successive layers, each layer comprising an annular series of substantially circular rings.  Large, highly-permeable packages of thread are thus produced which may easily and quickly be uniformly after-treated in package form and which may readily be unwound without tangling.  Referring to Fig. 1, spinning solution is extruded from spinneret 5 into coagulating bath 3, and the coagulated thread 6 is withdrawn, passed over godet 7 and subjected to a stretching operation in heated bath 4 by driving godet 10 at a higher peripheral speed than godet 7.  The thread is p  then passed over godet 12, where further tensioning may be effected, and allowed to fall into can 14.  If desired, either of godets 12 or 10 may be dispensed with.  Referring to Fig. 2, the can 14 is mounted for axial rotation upon a shaft 15 projecting through plate 16.  Plate 16 is affixed to shaft 18 for axial rotation therewith, and means are provided to drive the shafts 15 and 18 at different speeds from the same source of power.

Abstract: 1304637 Zone plates COLUMBIA BROADCASTING SYSTEM INC 19 April 1971 [15 April 1970] 21176/71 Heading G2J [Also in Division H4] A scanner for a facsimile system comprises a source producing a divergent beam of coherent radiation, a reflector positioned to converge the beam towards a point lying on an axis, and a spinner rotatable about the axis and having a spherical surface on which are formed a plurality of zone-type diffraction reflectors distributed circumferentially to reflect the converging beam to foci which describe circular loci concentric with the axis as the spinner is rotated. More than one of the zone reflectors are simultaneously illuminated by the converging beam so that a plurality of focal points are illuminated. As shown, Fig.1, a laser beam is passed through a modulator 12 and formed into a diverging beam 17 which is redirected and converged by a diffraction type reflector 18 towards a focus 23 on the axis of the spinner 20. The spinner 20 is hemispherical, the centre of curvature being at the focus 23, and has a plurality of zone diffraction reflectors 24 formed on its surface, each of which in turn focuses the beam to a focal point 26 which scans across a recording surface 28, e.g., a film strip, which is curved by a platten (not shown) so that it lies along the path described by the focal point 26, and is moved logitudinally past the spinner. The system is arranged so that when on focal point reaches the edge of the recording surface a second focal point is just moving onto the opposite edge so that no flyback time is required. A document may be read by omitting the modulator 12 and using the document instead of recording member 28, the light reflected from or transmitted by the document being picked up by a light sensor (not shown). In a modification, Fig. 2, (not shown), a geometrical reflector is utilized to converge the light beam and the end of the spinner is removed to form a truncated hemisphere. In another arrangement, Figs. 3 and 4 (not shown), the reflector is elliptical and has a slit and the spinner has the form of a central section of a sphere. The light reflected from the spinner passes through the slit in the reflector to the recording surface. In a further arrangement, Fig. 5 (not shown), the reflector is of the diffraction type and the divergent beam is directed with its axis parallel to the axis of the spinner and between the spinner and the recording surface. The zone diffraction reflectors may be produced by coating the spinner with a photo-sensitive layer and exposing it in the facsimile apparatus using a suitable mask in the beam and simultaneously directing onto the spinner a further light beam coherent with the first (e.g., from the same laser and using a series of mirrors) through the desired focal point. After the first expoure the spinner is rotated through a predetermined angle and re-exposed to produce a second zone diffraction reflector, the process being repeated until the whole circumference is covered. The layer is then processed to develop the holographic images of the focal points.
