Abstract: 1,118,252. Washing, sorting and disinfecting vegetables. HAITH ENGINEERS Ltd 7 Nov., 1966 [5 Aug., 1965], No. 33468/65. Headings A2D and A2Q. [Also in Division A4] In a process and apparatus for washing, sorting and disinfecting vegetable products, such as potatoes, beet and carrots, hereinafter referred to as potatoes, the potatoes fall, from a hopper 10, Figs. 1 and 2, on to the upper run of a travelling, continuous belt conveyer 11, which carries them to a washer 12, comprising conveying rollers 13 and overhead, perforated tubes 14, from which washing water is sprayed on to the potatoes. The washed potatoes then enter a grading device 16 comprising a pair of rollers 17, between which the smallest potatoes, namely "chats", fall on to a conveyer 19, and another pair of rollers 18, between which medium sized potatoes, constituting seed potatoes, fall on to a conveyer 20. Remaining larger or "ware" potatoes are carried by a conveyer 21, from the device 16 to a dryer (not shown). The conveyer 20 carries the seed potatoes to a sorting table 22, where they are sorted by operatives, and passed on to the upper run 47, Fig. 3, of an endless travelling conveyer 23. The sorted seed potatoes are guided, by deflectors 24, into sub-compartments 54b of an anular rotating drum-wheel 27 comprising two annular end-plates 38 connected by an outer, cylindrical, perforated wall 39. Perforated plates 40 divide the drum-wheel into a plurality of compartments 54, each subdivided, by a plate 55, into a large subcompartment 54b and a small sub-compartment 54a. Chats pass from the conveyer 19 on to a conveyer 25, and then on to a conveyer 26, from which the chats are deflected into the sub-compartments 54a. As the drum-wheel rotates, the chats in the sub-compartments 54a and the seed potatoes in the sub-compartments 54b, are retained in their respective sub-compartments by a shroud 49, and are carried through a treating liquid in compartment 33 of a tank 30. This liquid may be a disinfecting liquid, such as an aqueous solution or dispersion of an organo-mercury compound. The chats are then discharged, from the drum-wheel, by a conveyer 29, and the seed potatoes are discharged along the upper run 48 of an endless travelling conveyer 28. Vegetable products, particularly red beetroots, may be cooked by being carried, in said drum-wheel, through boiling water. Each end-plate 38 may have an annular rib 44 engaging four supporting wheels 45, at least one of which may be driven to rotate the drum-wheel around its horizontal axis 37. Alternatively, the drum-wheel may be rotated by sprocket and chain mechanism. The drum-wheel may be rotated intermittently by ratchet mechanism engaging teeth around the periphery of the drum, as described in relation to Fig. 4 (not shown).

[Class 98 (i).] In printing by contact or projection, the intensity of the printing light, is controlled by the adjustment of a meter foi measuring the density of the negative, so that a uniform time of exposure may be adopted As shown, the negative i and a strip k provided with a series of areas of graded density or a series of apertures of graded size are placed at opposite ends of a bent tube a fitted with mirrors f, g, h, which reflect rays from the negative and strip into an eye piece c so that the upper and lower halves of the field are covered respectively by rays from each source. The strip k is traversed across the end of the tube until the two halves of the field appear equally dense. This adjustment, through a contact m carried by the strip and slidable along a rheostat n in series with the printing lamp o, adjusts the brightness of the lamp to the value appropriate to the negative. In the lamp circuit is also included a switch clock which automatically times the exposure, and which requires resetting only when a change is made to sensitive material of a different kind. In a modification, the strip k carries a stud engaging a rotary switch arm carrying a contact wiping over a series of studs connected to tappings of the rheostat n. A further modification is referred to in which adjustment of the strip k varies the number of lamps in a composite printing light source. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which adjustment of the strip k alters the distance of the printing light from the printing surface. This subject-matter does not appear in the Specification as accepted.

Abstract: 834,996. Electron beam deflecting apparatus. GENERAL ELECTRIC CO. Oct. 27, 1958 [Oct. 29, 1957], No. 34306/58. Class 39(1). An electron-beam generator, which may be used in the irradiation of materials, includes a longitudinal deflection system comprising two serially-connected opposed conductors mounted in an extension chamber of the generator on opposite sides of or parallel to the axis of this chamber. Preferably, the generator also includes a principal transverse deflection system for deflecting the beam transversely across the conveyer belt 29. The conductors are preferably of stainless steel and may be hollow to enable a cooling medium to be circulated therethrough. Corresponding ends 40, Fig. 3, of the conductors may be electrically connected to the envelope 13 and to each other while the opposite ends 39 are insulated from the envelope and connected across a high frequency oscillator 15, Fig. 1, and a source of cooling fluid 19. Alternatively, corresponding ends of the conductors may be connected to a hollow ring 41, Fig. 4, at diametrally opposed points thereof, while the opposite end 42 of one conductor is electrically connected to the envelope and the opposite end of the other is insulated from the envelope. The conductors are preferably energized with an alternating current having a frequency such that the distance between successive cycles of the longitudinal deflection on an irradiated material is of the order of the diameter of the electron beam, i.e. a frequency of the order of 1000 times the principal transverse scanning frequency. The frequencies of the longitudinal and transverse deflections may be non-harmonically related to one another so that the longitudinal deflection cycles of successive traces are out of phase. As shown, the flared region of the envelope is provided with strengthening fins 21, Fig. 1 and terminates in a thin titanium window 23 which is bowed inwards and is cooled by air from a compressed air source 25.
