[Also in Division C6] An insecticidal compositions contains, as act- 'ive ingredient, at least one Bacillus thuringiensis strain falling within serotype 9 and/or the crystalline protein derived from this strain, in association with one or more of: (i) an inert carrier, which may be a solid, an oil, a liquid other than oil, or a combination thereof; (ii) one or more compounds known for use as a plant nutrient, fertiliser, insecticide, fungicide, herbicide, nematocide or acaricide, and (iii) a surfactant, with the proviso that when the inert carrier is wholly liquid other than oil, the composition contains at least one member of group (ii) or (iii). The composition may contain a mixture of a serotype 9 strain of Bacillus thuringiensis and/or crystalline protein derived from this strain, in association with a strain belonging to and/or crystalline protein derived from a different serotype 'of Bacillus thuringiensis. The classification of the serotypes of the species is described in detail on the basis of specified biochemical tests, esterase analyses and antigenic analyses. The compositions may be formulated as wettable powders or dusts (25, 50 or 75% toxicant plus solid carrier, dispersing agent, stabilizer, penetrant and/or sticker), granules (¢-25% toxicant plus stabilizer, slow release modifier and binding agent), emulsifiable concentrates (10-50% toxicant plus solvent, co-solvent, emulsifier, stabilizer, penetrant and corrosion inhibitor) and pastes (10-60% toxicant). Aqueous emulsions of the composition may be of the water-in-oil or of the oil-inwater type and may have a thick 'mayonnaise'- like consistency. Many conventional solid and fluid carriers and surface active agents are particularly mentioned. Example 1 demonstrates the enhanced yields obtainable by growing Bacillus thuringiensis on a medium containing distiller's solubles and casein. Example II discloses the improved insecticidal activity of the crystal/spore products of a serotype 9 strain as compared with that of a serotype 1 strain when assayed against Pieris brassica, Anagasta kuehniella and Bombyx mori.

Abstract: 1307438 Photo-electric measurement of velocity BROWN BOVERI &Co Ltd 19 Nov 1970 [21 Nov 1969] 55080/70 Heading G1A [Also in Division H4] In laser fluid flow measurement apparatus of the type wherein a beam from a laser 2 Fig. 1 is focussed in an area F of a fluid flow pipe 1 and doppler shifted scattered light (path 6, 7, 8, 9) is mixed with unscattered light (path 5, 9, 10, 9) at a detector (photo-diode PD) to give a doppler beat frequency signal proportional to a component of the fluids velocity, the envelope of the frequency spectrum of the doppler signal has the shape of Fig. 2. The frequency having the maximum  amplitude is due to fluid particles on the axis of the beam and the greater and lesser frequencies having smaller amplitudes are due to off-axis particles but still within the volume of resulution F. To decrease the volume of resolution only those frequencies having amplitudes above a predetermined threshold are measured. The upper threshold shown in Fig. 2 thus gives the reducer resolution width R2.

Abstract: 1333096 Occluding and restricting blood vessels J A HUNTER and R W SESSIONS 23 Nov 1970 [21 Nov 1969] 55587/70 Heading A5R A device for insertion into a blood vessel to effect restriction or occlusion thereof comprises an elongate, hollow, fluid-tight, smoothwalled, expandible body 1, Fig. 2, having a tubular wall 5 which is more deformable than end portions 4, one of which is constructed for detachable mounting on an insertion device with the aid of which the body 1, in use, is placed at a desired location and is expanded to form an axially-extending circumferential band engaging the blood vessel and distributing the resulting outwardly diverted forces on the vessel over an area to protect the blood vessel from concentrated puncturing or rupturing forces, the body 1 being-constructed to maintain its state of expansion at said location on release from the insertion device. The body 1 may be expanded by means of a spring 6, or by introducing fluid thereinto via a threaded port 7, Fig. 4 having a flap valve 8, or via a smooth-bore port with a ball valve, or via a self-sealing end portion. For effecting restriction rather than occlusion a blood by-pass passage extends sealingly through the body, Figs. 9, 10 (not shown). The body 1 is introduced by retaining it adjacent to the end of a conduit 11, Fig. 1, connected via an adapter 35 to a syringe 31 having a piston 32 therein. Prior to insertion into a blood vessel, the body 1 of Fig. 2 is contracted by relative movement between a wire 42, extending through conduit 11 and connected to piston 32 and engaging the inner wall of one end part 4, and the conduit 11 which engages the outer wall of the other end part 4. The fluid-expanded bodies 1 may be expanded by fluid moved by piston 32, the wire 42 being omitted. The inner end of conduit 11 may have a fitting allowing reconnection to the body 1 for subsequent contraction and removal. The conduit 11 may extend through a tube 36 having a Y-fitting 39 through which fluid may be introduced into tube 36 to allow determination of the location of the body 1 in the blood vessel by for example, X-rays. Alternatively, fluid introduced into the body 1 may be a contrast medium. The fluid may alternatively be a liquid which solidifies after introduction into the body 1.

Abstract: 564,096. Brake-operating mechanism. COMMER CARS, Ltd., and WHITE, G. H. Dec. 8, 1942, No. 17457. [Class 103 (i)] A hand lever is arranged to turn initially about one pivot and when the slack has been taken up and a predetermined force has been applied, about a second pivot whereby the braking pressure is applied at high leverage. According to Figs. 1 and 2, the hand lever 1 is mounted on a pivot 2 carried by the arm 5a of a lever 5 pivoted at 4 to a fixed support 3. The other arm of the lever 5 has ratchet teeth 9 normally engaged. by a spring-loaded pawl 8 carried by the lever 1 and adapted to be disengaged by a lever 1a, a rod 7 and an arm 17a pivoted on the lever 1. The lever 1 is connected at 6a to the brakes by a rod 6.

Initial movement of the lever 1 takes place about the pivot 2, the pawl 8 slipping over the ratchet 9, but when the slack has been taken up so that the force applied is sufficient to disengage the detent 13, the levers turn together about the pivot 4. In a modification, Fig. 3, in which the parts are duplicated on the two sides of the lever 1, the pawl 8 is pivoted at 8a to the lever 1 and is urged to engage a ratchet 9 on the upper edge of the arm 5b by a torsion coil spring 8b carried by a pin 8f on a plate 8e also pivoted at 8a on the lever 1. A pin 8c on the pawl is free to move in a slot 8d in the plate 8e. To permit the lever 1 to be held in any position it is provided with a pawl 1e mounted in a similar manner to the pawl 8 on a pivot 1f and adapted to engage a fixed ratchet 3b. Rods 7, 7c for operation of the pawls by the handgrip are connected at 7b to the plate 1k, the rod 7 engaging also in a slot 8g in the plate 8e. Rollers 1d on the end 1b of lever 1 engage the arm 5b of the lever 5.
