Abstract: 1,148,669. Deflecting propulsive gases. ENTWICKLUNGSRING SUD G.m.b.H. 24 Oct., 1966 [29 Oct., 1965; 16 Nov., 1966], No. 47723/66. Heading B7G. A jet pipe for an aircraft propulsion unit 30 comprises a series of rotatable tubular sections 212, 213, 214, Fig. 10, interconnected along oblique planes with means mounted on a section for rotating the succeeding section due to the relative motion of this preceding section. The sections 212, 213, 214 are rotated at the same speed but in alternating directions, as shown by the arrows on Fig. 10, thereby deflecting the thrust of the jet pipe efflux, so that the thrust line remains within the vertical plane of the jet pipe entry 11. The means for rotating the neighbouring sections may comprise two intermeshing gearwheels 604, 605 rotating about shafts mounted on one section 213 each engaging a rack 124 or 125 on the neighbouring section 212 or 214 whereby the relative motion of the section 212 is passed to the section 214. A modified form of this means, Fig. 15, is required to rotate section 213, because the jet pipe entry 11 is stationary and has only half the speed relative to section 212 required for section 213. The section 212 may be driven by a motor (70) and chain (71) drive, Fig. 9 (not shown). An alternative to the intermeshing gears 604, 605 may comprise a carriage 60, Fig. 5, mounted on circumferential rails round section 13 having parallel passages into which slide rods 61, 62 pivoted to brackets 121, 141 on sections 12, (14), Fig. 4 (not shown). Relative movement of section 12 will cause the carriage to move round section 13 thereby moving section (14) in step with section 12. The jet pipe may comprise more than three sections 212, 213, 214, each section excluding the last having means for rotating the succeeding section(s).

Abstract: 1,174,778. Hydromechanical change-speed gear. H. EBERT. 23 Nov., 1967 [25 Nov., 1966; 20 Oct., 1967], Nos. 52772/66 and 47816/67. Heading F2D. A hydromechanical transmission comprises parallel mechanical and hydrostatic gear paths in which the latter gear can be locked solid at an intermediate ratio between high and low to give a purely mechanical drive. In a first arrangement, provisional Specification 1,174,778 the input shaft 10 drives the output shaft 16 through a layshaft 36 and epicyclic gear units 15 ... 20, with swash-plate type closed circuit hydrostatic units 25, 29 between intermediate shafts 24, 27. Swash-plates 26 of units 25 are fixed while plates 30 of units 29 are adjustable. The shafts 27, 16 carry pinions 12, 38 with disc clutches 28, 39. At starting clutch 39 is engaged and clutch 28 disengaged, the units 25, 29 acting as pumps and motors respectively. The drive is mixed mechanical and hydraulic, the inclination of swash-plates 30 being reduced to increase speed, until when plates 30 are at zero setting the hydrostatic gear locks solid and a purely mechanical drive is transmitted through the epicyclic gear. To increase speed clutch 28 is engaged and clutch 39 released and operation of the hydrostatic units is reversed so that maximum speed is reached with swashplates 30 at their full negative setting. In a second arrangement, provisional Specification 47816/67 (not shown), the input shaft 10 is connected to clutch-engaged forward and reverse layshaft gears (13, 19) and both swashplates (31, 34) are adjustable, locking of the hydrostatic units for mechanical drive occurring with plate 34 at zero setting.

Abstract: 1,160,255. Monostearyl fumaric acid derivatives. CHAS PFIZER & CO., Inc. 26 Oct., 1966 [18 Nov., 1965; 27 Sept., 1966], No. 48133/66. Heading C2C. [Also in Division A2] Finely divided monostearyl fumaric acid or the sodium, potassium, calcium or magnesium salt thereof, having a surface area of at least one square metre per gram and consisting of particles having an average spherical diameter up to 5 microns, may be obtained from the corresponding fumarate, consisting of particles substantially all of which are at least 5 microns in diameter and 95% of which are at least 10 microns in diameter, by conventional methods, for example by dry-milling or by recrystallizing from hot fats and oils or from aqueous media the corresponding macrocrystalline form. The dry-milling process, which is a preferred method for the preparation of microcrystalline monostearyl fumaric acid, may be effected by employing any conventional milling and classifying equipment, e.g. jet mills, ball mills or other impact mills, pin mills or micronizers. The process of recrystallization from a fat or oil, e.g. cottonseed, soybean, safflower or corn oils or low-melting solid shortenings, e.g. lard and hydrogenated vegetable shortenings, may be effected by dissolving the macrocrystalline form in the edible oil or liquid fat system at elevated temperature, e.g. 100-140‹ C., and rapidly cooling the solution with agitation. The aqueous recrystallization process may be effected (i) by solubilizing the macrocrystalline compound in the aqueous medium by heating to a temperature slightly below the boiling point of the medium and then rapidly lowering the temperature of the system to at least 70‹ C., or (ii) by a continuous process by slurrying the macrocrystalline fumerate in the aqueous medium, feeding the slurry through a heat exchanger, holding the slurry at the solubilization point and thereafter flashing off the water.

Abstract: 1,110,085. Automatic exposure control. EASTMAN KODAK CO. Oct. 27, 1966 [Oct. 28, 1965], No.48176/66. Heading G2A. An exposure is made by a first shutter member uncovering an exposure aperture which is then closed by a second shutter member, the latter being controlled by an electrical circuit triggered by the signal from a light-responsive element. The first shutter member is a disk 2, and in the initial cocked position Fig. 1 (not shown) closes off the exposure aperture 1, being held in that position by the release 3 which latches in front of a projection 16 on disk 2. When the release 3 is operated, disk 2 is driven clockwise by its tensioning spring, and an arcuate slot 10 therein uncovers aperture 1, so initiating the exposure. The second shutter member is a blade 6 pivoted on a pin 11, and is actuated, via a link 7, by a relay R. A photo-sensitive cell 4 is moved to the position 4A, and initially (Fig. 1) is closed off from scene light. As shutter member 2 begins to rotate, cell 4 is progressively uncovered by a wedge-shaped opening 9 in the shutter. Thus a constantly increasing signal is received by the transistor circuit (Fig.l) until a predetermined voltage level is reached, which activates a trigger circuit and hence operates relay R, causing shutter member 6 to pivot and close aperture 1. This termination of the exposure is the position shown in Fig. 2. A spring-loaded detent d holds member 6 in this position, and a pin 8 on the latter engages with ratchet teeth 12 on member 2 to prevent further rotation. The mechanism remains in this condition until member 2 is rotated counter-clockwise to re-cock it. For flash operation, cell 4 is moved from behind the shutter to the position shown in full lines. The flash bulb L is ignited as shutter 2 rotates by a projection 15 on the latter, which closes the flash switch S 3. Cell 4 then responds to increasing light from the bulb, and operates the trigger circuit as before. Fig. 3 (not shown) is a modified form of shutter in which the time-light integration is effected by circuit components, so that the wedge opening 9 is not necessary.
