Screw propellers; propelling, steering, and manoeuvring by water jets; rudders; steering- gear; submarine vessels, special apparatus for steering. - Relates to augmenter tubes for screw propellers of the kind described in Specifications 124,047 and 141,445, and consists in making the duct immediately in the rear of the propeller of square or oblong section, while the front is circular with or without an intermediate oval section. The steering and manoeuvring pallets close on to the tube at their forward end for full ahead running, and when their rear edges touch for astern running the forwards ends cooperate with the tube to form nozzles substantially parallel with the tube axis. The tube a, Figs. 2, 3, is of circular section at its forward end and merges into a square section at the rear, the top and bottom carrying pivots for the pallets d, e. Rigid with the tube and external thereto are nozzles f. The pallets have inwardly projecting brackets d<1>, e' for keeping the pivot axes near the tube axis, and are shaped at the rear edges i so as to be in contact over a large angle of movement. Steering is effected by connecting the posts g and tiller arms thereon by cables k which pass over drums f having steering wheels j<1>. The drums are normally clutched for joint operation for steering, but axial movement allows separate action for manoeuvring. In a modification for aircraft, the tube has an intermediate oval section, a centre stream line body is placed within the tube, and the axes of the pallets are on the walls. For aircraft and submarines, the pallets may be on horizontal axes for controlling the movements of the vessel in a vertical plane.

Title: Locking device for a safety belt
IPC: B60R22/40
Filed: 1975-07-03
Abstract: 1510509 Retractor reel S M LINDBLAD 3 July 1975 [8 July 1974] 28053/75 Heading A3V A seat belt retractor reel comprises a locking pawl mechanism including a pivoted, spring-biased, arm in which the line of action of the spring can be switched from one side of the arm to the other at the dictates of an inertia sensing member to lock or release the ratchet wheel. As shown in Figure 1 a pivoted pawl 3 is moved by a bifurcated arm 7 the lower end of which rests on a support 8. The arm itself is biased by a spring 10 attached to a pivoted arm 11. If the inertia mass 13 is displaced, so pivoting arm 11, the line of action of the spring is displaced to the right of arm 7 so forcing the pawl into the ratchet teeth. In a modification (Figure 2, not shown) the upper end of arm 7 functions as the pawl. As shown in Figure 3 the pawl arm 7 is biased by spring 10 attached to a fixed pivot. A vertical extension 29 of the pivoted sensing arm 23 lies against, and deflects, the lower part of the spring. If the inertia ball 25 is displaced, the spring is allowed to straighten so that its line of action lies to the left of the pawl arm which is thereby pulled into the ratchet teeth.

Abstract: 823,417. Boring earth. COMITETUL GEOLOGIC DE CERCETARI SI EXPLORARE A SOLULUI SI SUBSOLULUI. Sept. 13, 1956, No.28069/56. Class 85 A core bit is formed so that the bulk of the drilling fluid is returned to the surface without passing over the teeth of the bit. The bit has an internal ring 35 fitted adjacent the teeth 32, and a slot 36 extending from between a pair of teeth, the aperture formed by the slot and the ring being the passage for the bulk of the drilling fluid. When after drilling, the desired length of core 18 is obtained, the supply of fluid to the bit is cut off by means of a sleeve valve located in the drill string and moved by the pressure of the fluid acting on a ball which is dropped down the string. Drilling is then resumed, and the heat generated causes the core to be separated from the bottom of the hole and fixed within the bit. A bit is also described (Fig. 1, not shown), which has a split ring having internal teeth which tend to grip the core during removal of the bit from the hole.
Patent GB-467719-A (GB)
Title: Improved manufacture of asphaltic or bituminous emulsions
IPC: C08L95/00
Filed: 1936-10-16
Abstract: Stable acid-reacting bituminous emulsions are obtained by treating a basic emulsion produced with the aid of for example sodium hydrate, sodium silicate and/or trisodium phosphate with small quantities of citric acid or extracts of chestnuts or gall-nuts, containing tannin, in two stages, the acid or extract used in the first stage being previously treated with sodium hydrate.  Substances such as algin or casein may be added to the basic emulsion, and retard the action of the acids.  For example, a basic sensitive emulsion of pH value 11--12, consisting of 65 per cent bitumen and 35 per cent water and obtained with the aid of about 0,25 per cent basic emulsifying agent is agitated in the cold with 1 per cent of a solution of citric acid or chestnut extract, which consists of a 33 per cent solution of the acid treated with 5--8 per cent of sodium hydrate.  Then a further 1--2 per cent of the untreated acid solution is added, the emulsion acquiring a pH value of about 6.  The resulting emulsion can resist the action of acids, alkalies or fillers without breaking.

Title: Film casting apparatus
IPC: B29C48/03
Filed: 1957-09-10
Abstract: <PICT:0806511/IV (a)/1> <PICT:0806511/IV (a)/2> In a film-casting apparatus comprising a container for a coagulating bath, a nozzle on the container for extruding a film-forming solution into the bath, and a set of bars normally positioned in the bath and under which the freshlyextruded film is drawn before it is removed from the bath, a mechanism is provided for raising the bars to the surface of the bath to permit initial lacing of the film around the bars.  As shown in Fig. 1, viscose is extruded through a slit orifice at the base of casting nozzle 18 into an acidic coagulating solution filling the casting tank 10 to the level 12.  A stream of fresh solution is continuously admitted to the tank through line 13 and used solution is discharged into an overflow trough 15 and drain-pipe 16.  The extruded viscose is immediately coagulated into a film 20 which is advanced under a radius bar 21, over to and under straight bar 35, and then up past a wiper bar 36 and on to a driven draw roll (not shown) which pulls the film through the bath.  Radius bar 21 is mounted on pivots 22 at the outer ends of two crescentshaped beams 24, 25 which are pivotally mounted at their other ends on lugs 26, 27 on the inside surface of the casting tank.  The radius bar is rotated about its pivots by means of a worm and worm gear set 28, 29 which is mounted on beam 25. The stem of the worm 28 is long enough to protrude above the surface of the coagulating bath so that it can be reached by turning means and thus enables the radius bar 21 to be rotated even when at its maximum depth of immersion.  A second set of crescentshaped beams 31, 32 is pivotally mounted on the side walls of the tank at journals 33, 34 with a straight but fixed bar 35 extending between them at one end.  Tie links 40, 41 are provided between the beams on each side so that when one beam is moved the other is pulled with it.  Beams 24, 25 are connected by links 42, 43 to a shaft 45 which is journalled at its ends into the tank wall. Shaft 45 is rotated by a connectingrod 46 and piston-rod 47 actuated by an hydraulic cylinder 49 pivoting in the mounting 50 fixed on the outside of the machine frame.  Liquid under pressure can be introduced into the cylinder 49 through lines 52, 53 communicating with a control valve.  When the machine is ready to be threaded the operator causes cylinder 49 to raise beams 24, 25 and 31, 32.  Radius bar 21 and fixed bar 35 are thereby raised through a substantially vertical path and by substantially the same amount so that they are both close to the surface 12 of the casting bath, as indicated by the upper dotted arrangement in Fig. 1.  Also, by means of the worm gear set 28, 29 the radius bar 21 is rotated so that its plane of curvature is horizontal.  The operator then threads the film under the radius bar 21 and back bar 35, up over the wiper bar 36, and around the upper roll (not shown).  The bars are then lowered to the desired depth.  The apparatus may also be used for the casting of cellulose ether films.
