Designs resembling marble or granite are produced by preparing a photographic image of the genuine marble &c., forming a printing surface, e.g. a silk-screen or a printing plate, from the said image, and printing the design from the said surface, a coating of polyester resin incorporating ground marble or granite &c. being applied after the printing step to complete the design. In one example imitation Greek marble is produced by coating a polished glass plate with polyester resin and printing on the resin with a green ink using a screen prepared by photographing the original marble. The printed coating is then surrounded by a frame and provided with a backing of a catalysed polyester composition including marble dust. The frame and glass are subsequently removed. The polyester may be abraded and polished and a backing layer, also of polyester, may be applied.

In a root-crop harvester the shares 1, 2, are carried by a support 3 pivoted about an axis 4 on the main frame 5 of the machine and are connected by linkage 6-11 to a beam 32 axially movable on the frame to raise or lower the shares about the axis 4, the linkage including a manually-releasable locking mechanism 15-18 which retains the shares in the raised position, the beam 32 forming the drawbar of the harvester, being mounted between rollers in a bracket 34 on the frame 5, and being connected by a pivoted link 29 to one arm 8 of a Y-shaped lever pivoted at 9 on the frame and connected by its remaining arms 6, 7, to a member 11 fixed to the support 3 and to a member 15 forming part of the locking mechanism. The locking mechanism comprises a standard 18 through which the member 15 slides, the member having a notch 16 engageable with the slot 17 in the standard under the pressure of a leafspring 21. The notch is released by a pull on a cable 27 attached to one end of a pivoted bell-crank 24, the other end carrying a roller 26 to lift the member 15. To raise the shares out of ground-engagement, the towing tractor is backed, thus pushing the beam 32 backwardly and rotating the Y-shaped lever clockwise until the notch 16 re-engages in its slot.

Title: Epicyclic variable ratio transmission apparatus
IPC: F16H15/50
Filed: 1963-02-11
Abstract: 953,161. Variable-speed gear. C. P. R. DE VILLIERS. Feb. 11, 1963, No. 5570/63. Heading F2D. A continuously variable-ratio gear between driving and driven shafts 1, 20, comprises friction discs 2, 12 with tiltable planetary rollers 4 between them mounted on an axially slidable carrier 6. Either the planetary rollers 4 have a convex cross-section, as shown, or alternatively at least one of the discs 2, 12 has a convex cross-section, Fig. 3 (not shown). One disc 2 is of generally conical or bell-shape. The disc 12 acts as the reaction member. The carrier 6 is in splined engagement 10, 11 with a rotary servo cylinder 9 fast on the driven shaft 20, and carries a piston 8. Selective admission of oil under pressure through holes 32, 33 to the opposite sides of the piston 8 slides a sleeve 7 and the carrier 6 axially, and thus tilts the rollers 4 to change the ratio. When the ratio approaches direct drive, the radially inward ends of the planetary rollers 4 run on to a thrust ring 42 splined for rotation with the servo cylinder 9 and the driven shaft 20, so that no relative rotation occurs between the parts. A spring 26 acts between the servo cylinder 9 and a piston 22, fast with the driving shaft 1 and the disc 2, to bias the latter out of engagement with the planetary rollers 4. To take-up drive, a valve 40, Fig. 2, is closed and oil from a pump P enters a space 27 in the servo cylinder 9 to act on the piston 22 and overcome the bias of the spring 26, thus sliding the disc 2 into engagement with the planetary rollers. The torque acting on the reaction disc 12 acts through a connecting rod 34 upon a valve piston 35, thus moved in a direction to close, increase the pressure in the pipe 38 and in the space 27, and increase the friction loading on the planetary rollers 4.

Abstract: 566,282. Cracking oils. TRINIDAD LEASEHOLDS, Ltd., and HENE, E. April 30, 1941, No. 5627. [Class 32] Hydrocarbons, e.g. mineral oils, synthetic petroleum, oil shales, tars, are treated to produce gasolines or gas oils of improved Diesel Index by heating them rapidly in film form to temperatures in the range 400-550‹ C. while in the presence of catalysts, comprising the elements of the Fifth Group of the Periodic system or compounds thereof. The catalyst is preferably used in the form of a distillate obtained in a previous run which contains a small percentage of the catalyst in combined form. The hydrocarbon may be brought to the required temperature as described in Specification 566,281, e.g. by distributing it over a bed of small coke which is heated and agitated. In examples : (1) a Trinidad crude oil topped at 360‹ C. is mixed with 2 per cent arsenic powder and sprayed onto a layer of coke kept moving by a revolving agitator, carbon dioxide being passed over the surface of the coke. A distillate of which 6 per cent boils below 200‹ C. and 90 per cent below 360‹ C. was obtained. (2) The process set forth (1) was repeated, using as catalyst a part of the distillate obtained in (1), boiling about 250‹ C. and containing about 0.04 per cent arsenic. An improved yield was obtained at a temperature of 430‹ C.

Title: Determination of vapour flux and or composition
IPC: G01B15/00
Filed: 1973-02-07
Abstract: 1394155 Cyclotron resonance spectrometers BATTELLE DEVELOPMENT CORP 7 Feb 1973 [9 Feb 1972] 5989/73 Heading G1N [Also in Division C7] The flux and/or composition of a vapour at low pressure, e.g. in a vacuum deposition apparatus, is determined by isolating a stream of vapour particles and ionizing a packet of the particles in the presence of a magnetic field so that the packet moves around a circular path and induces an electric signal in an electrode. Each component of the vapour moves around the path at a frequency dependent on its mass, so that by recording the signal amplitude at different frequencies the flux of the components of the vapour may be found. Fig. 1 shows a vapour deposition apparatus having a heated crucible 4 in a bell housing 1. The workpieces 11 on which material is to be deposited are adjacent a probe 12 in which the vapour is ionized and analyzed. The probe is shown in a side view in Fig. 2 and basically comprises a conductive box on a base plate, the stream of vapour passing through aligned holes 23, 36 and 37. A permanent magnet 21 provides the magnetic field, and has pole pieces visible only in Figs. 3 and 4 (not shown). The vapour stream is ionized by a pulsed electron beam which passes through it at 40, and the ions move in the circular path 59 adjacent pick-up electrode 43 and optional pick-up electrode 43'. Two of the opposite faces of the probe box are insulated from the rest of the box and may have a potential applied to them to purge the ions out of the path every 50-100 orbits to prevent difficulties arising from ions diffusing along the path. The electron beam source is preferably modulated to pulse the vapour stream once per orbit to maintain the motion around the path. The modulation and the purging may induce signals on electrode 43, and to counter this corresponding signals may be coupled to lead 44 by electrode 55. By altering the frequency to which the detecting circuitry attached to electrode 43 is tuned, Fig. 5 (not shown), the signal magnitude at different frequencies may be measured, giving a spectrum analysis. Alternatively the permanent magnet may be replaced by an electromagnet whose current is varied while the detection circuitry tuning is unaltered.
