Title: Improvements in or relating to grain harvesting machines
IPC: A01D41/08
Filed: 1943-10-20
Abstract: 572,040. Harvesting grain. McCONNEL, F. W., and BOMFORD, D. R. Oct. 20, 1943, No. 17287. [Class 6 (iii)] A grain harvesting machine, which threshes out the grain from the ear before the stalk is cut from the ground, comprises gathering members 30 which provide tapering spaces for directing the stalks between one or more pairs of beater members, the latter being rotatably mounted on a carriage 10 in such manner that the parts which first engage the crop are moving upwardly, and being arranged to provide a gap between them for the reception of the ears. Further a casing 34 surrounds the latter members and serves to catch the grain separated from the ears. In the construction shown, the carriage -10 is connected by a bracket 11 to a power-driven vehicle 12 and is supported by land wheels 13 fixed to an axle 14. The latter drives shafts 21, 25, through chain and sprocket gearing and pinions 19, 20, the shafts and the easing 34, being mounted 'on a sub-frame 45 vertically adjustable by means of screw-jacks 47 with respect to the carriage. The shaft 25 carries the beaters each of which comprises a disc 26 having a hub portion 27 and a boss 9 within the hub. Each disc is formed on either side thereof with beater arms 28 which decrease in width and depth as they extend outwardly, and which have leading surfaces each inclined to a radius while their trailing edges extend radially. The arms on one side of a disc are staggered with respect to those on the other side and also with respect to those of the adjacent disc. Each disc has secured on either side of its periphery an annulus 29 by blades 50, the blades serving to create a draught to sweep up any grain which falls into troughs 32 formed integrally with the members 30. The grain is discharged into a trough 38 from which it is taken by an elevator 39 to be delivered to a hopper 40 and thence to a sack 41. In a modification, the elevator is dispensed with, and the blades 50 are employed to sweep the grain through a conduit and thence to a sack, and in another modification the discs 26 are of conical form. Other modifications relate to various ways of fitting or connecting the harvesting device to a motor vehicle.

Abstract: 1,136,016. Silica sols. MONSANTO CHEMICALS Ltd. 28 March, 1967 [21 April, 1966], No. 17567/66. Heading C1A. [Also in Division C7] A sol contains from 1 to 30% by weight of the total composition of collidal silica in a dispersion medium comprising a monohydric alcohol having from 1 to 3 carbon atoms per molecule, up to 10% by weight of the alcohol of water and from 0À1 to 10% by weight of the total composition of hydrochloric acid (expressed as 100% HC1) or from 0À1 to 15% by weight of the total composition of sulphuric acid (expressed as 100% H 2 SO 4 ). The novel colloidal dispersions of silica that are of most value in practice contain from 4 to 30% by weight of silica, and not more than 5% by weight of HC1 or H 2 SO 4 , and preferably from 0À25 to 5% by weight of the alcohol of water Compositions described in examples 1 to 9 are claimed per se. The silica sols are produced by passing an electric current through a liquid medium comprising the above composition using a silicon anode in contact with the liquid medium. The alcohol is preferably ethanol or methanol and the anode is substantially pure silicon or ferrosilicon containing from 60 to 99% by weight of silicon. The process is most conveniently carried out under reflux at the normal boiling point of the liquid medium, and preferably includes a preliminary period of "anode activation" during which an electric current is passed through the liquid medium with the electrode that is to serve as the anode in the production of the silica sol as the cathode.

Divided on 385,683. [Class 56.] In a glass-blowing machine having divided neck, parison, and finishing moulds revolving round a common axis, the halves of the parison mould are pressed tightly against each other and against the neck mould by the parison mould carrying arms in their closing movement, so that entrance of air between the mould sections is prevented. A parison mould 16 is carried by arms 66 on a pivot pin 67 and registers with a neck mould 15 prior to gathering by suction. Each mould section 16<1> is connected to a holder 70 comprising an arcuate bar 71, cam plate 72, and slotted extension 73, through which a bolt 75 extends into the arm 66. The cam plate 72 carries a stud 76, projecting into an opening 77 in the flange 78 of the mould, and fits within a groove in the arm 66, its inclined cam surface 79 contacting with the bottom 80 of the groove so that the pressure exerted by the arms 66 causes a vertical movement of the mould. Pads 66a on the arms 66 support the mould 16 until it begins its upward movement when the weight is taken by pads 71a on the holders 70.
