Abstract: 1,250,197. Screw propellers. H. KUBOTA. 11 Oct., 1968 [12 Oct., 1967], No. 48408/68. Heading B7V. A freely rotatable counter-propeller 3 is of larger diameter than the (conventional) main propeller 2 and situated a short distance behind same. A flank 3b 1  of the blade receives the turbulent back-flow and is driven thereby; the surface 3b 2  acting to assist propulsion of the ship. Flank 3b 1  has a lower pitch than that of both the main propeller and the surface 3b 2 . The portion 3a of the counter-propeller, that lying outside the diameter of the main propeller, is narrow and the blade thickness increases suddenly between 3a and 3b and thereafter gradually narrows as shown.

A radial bearing which has circumferentially spaced bearing blocks 3c mounted in a support ring 1a, 1b is made by fixing the blocks in the support ring and machining bearing surfaces on one radial end of each bearing block so that the surfaces lie on a common circular cylindrical surface the diameter of which is greater or lesser than that of the member to be journalled according to whether such member is a shaft or bearing shell, the blocks then being moved radially and fixed in their bearing position in the support ring. The blocks may be of circular cylindrical outer periphery fitting in bores in the ring. The bores may be blind, and after machining, shims 34 are inserted at the bottom of the bore to position the blocks in the bearing. The support ring may comprise two separate halves which are secured together with dowels 30. Screws 32 for adjusting the position of the blocks may also be provided. Alternatively bores may be provided through the ring and the blocks are maintained in position by the engagement of the end of the block remote from the bearing surface engaging with the housing.

In a cathode-ray display tube using postdeflection acceleration, wherein the deflection system is shielded from the acceleration field by means of a grid electrode, the grid is supported over at least a part of its periphery by a frame member which is shaped so that the electron beam can strike it substantially only in regions from which secondary electrons and/or reflected electrons do not reach the screen, thereby reducing "flare". In Fig. 2 the grid 17 comprises a number of parallel wires 18 extending between a pair of bars 19 of 4 x 4 mm. cross-section which are held apart by spacers (not shown). A strip of metal 20 0À2 mm. in thickness is welded along the edge of each bar to prevent the electron beam from striking the surface 22. In another arrangement (Fig. 3, not shown) the surfaces 22 are bevelled so that they are protected from the beam by the projecting portion of each bar on the side nearest the deflecting system. The accelerating field may be provided by a resistive wall coating joined at each end to graphite wall coatings (Fig. 1, not shown).

As a further alternative, there may be a fixed wall surrounding the conveyer chain. In the latter case, the links may slope downwardly so that articles are discharged through an aperture formed in the wall. The conveyer may be disposed between a cigarette packer-machine and a wrapper machine. On shut-down of the wrapper, a stop is positioned in the path of the articles at the point of discharge from the conveyer. The latter carries on running and the packages accumulate on the conveyer. The links 16 may be of nylon and acetal resins. A fixed cam surface of low friction material may be provided to guide the chain into a spiral form at its entry to each of the members 50, 52.

Abstract: 1321304 Altering physical properties; making sheets EXORS OF JAMES MILLS Ltd 10 May 1971 [9 May 1970] 22521/70 Headings B3A and B3V Physical properties of pearlitic or ferritic pearlitic steel are improved by austenitizing the steel, subjecting it to a first rolling or swing- forging stage while it is in the austenitic state so as to perform a major part of the reduction in area required of the complete process, cooling the steel or allowing it to cool until transformation of the austenite to pearlite or to ferrite/pearlite has substantially been completed, and in a second rolling or swing-forging stage reducing the steel by at least a further 60% commencing at a temperature below the temperature at which phase transformation from pearlite or ferritepearleit to austenite commences but not below 500‹ C., without re-heating or equalization during rolling or swing-forging and without any substantial retransformation of the ferrite/ pearleit or pearlite to austenite. After the first stage, the steel is cooled or allowed to cool to 690-500‹ C. for the second stage, or it may be stored at ambient temperature and then reheated for the second stage working. The steel is not removed from the mill between passes during the second stage reduction of 60-85% and is austenitized before the first stage by heating to 900-1300‹ C. The steel may have a carbon content of 0À2-0À7% and include Mn, S, Ph, Si, Ni, Cr, Mo, Cu and Sn, two examples being given. Cooled rolls may be used during the second stage and the steel may be cooled between passes by a water spray. After cooling, following the first state, the steel may be discharged into a soaking or equalizing furnace for equalizing the temperature before the second stage. A conventional mill may be provided with one outlet for conventional rolling and another for rolling according to the invention, via a soaking furnace.

Abstract: A method for producing agriculturally active substances such as pesticides to provide improved resistance to environmental degradation, especially heat and ultra-violet light. The method involves the direct reaction of an active protein toxin of a biologically derived pesticide with a UV protectant to form a stable complex having the UV protectant as an integral part of its structure. The method employs lignosulfonates, such as sulfite lignin or sulfonated lignin, or alternately sulfonated lignite, sulfonated tannins, napthalene sulfonates or other related compounds as the UV protectant.
