Abstract: The present invention relates to a light, biodegradable, organic pigment and filler, and a method of manufacturing it. According to the present invention, a solution comprising a starch derivative is first prepared by dissolving the starch derivative into a suitable solvent, and, after that, the solution is brought into contact with a non-solvent to precipitate the starch derivative from the solvent, and, as a result, a dispersion is obtained, one which comprises a precipitate consisting of starch derivative and a liquid phase formed of the solvent and the non-solvent, after which the solvent is removed from the liquid phase and the precipitate is separated from the non-solvent and recovered. The present invention can be used to manufacture both a product comprising 100-300 nm spherical particles, which is suitable for use as a pigment, and a coral-like, porous product which is particularly suitable as a filler.

Abstract: 1,225,867. Acetoacetic acid esters. LONZA Ltd. 23 July, 1968 [27 July, 1967], No. 35111/68. Heading C2C. Acetoacetic acid esters are prepared by introducing diketone, an alcohol and an acidic catalyst into a reaction medium which is the product of a reaction between diketene, the alcohol and the acidic catalyst and comprises an acetoacetic acid ester and a #-alkoxycrotonic acid ester. The temperature of the mixture is kept between 90‹ C. and its boiling point while the secondary products formed boiling below the reaction temperature and unreacted alcohol are separated off by distillation. The reaction product is then rectified in the presence of water after distillation of the catalyst and resinification residues. The molar ratio of water to #-alkoxycrotonic acid ester is at most 3: 1. During this rectification the #-alkoxycrotonic acid ester is converted into acetoacetic acid ester which is all recovered by distillation.

Abstract: 1,227,637. Controlling winches. HARNISCHFEGER CORP. 1 Oct., 1969 [10 Oct., 1968], No. 48147/69. Heading B8B. [Also in Division F2] The control means for a power transmission mechanism of a truck crane comprises a pair of levers 22, 23 which are each swingable to control through hydraulic valves 26 or 27, an associated clutch 26b, 27b on hoist drums 8, 9, each lever being provided with a twist grip which through a cam device linearly actuates a cable 34 to modulate through an hydraulic value 42, a torque converter TC controlling the drive speed to the drums 8, 9. The converter TC is driven from a modulatable clutch MC at one end of a power unit E. Each valve 26, 27 normally in a spring maintained neutral position in which pressure fluid from a pump P<SP>1</SP> is passed through the valve to reservoir, is operable by the levers 22, 23 to vary the hydraulic actuating pressure for the drum clutches 8a, 9a. The speed of drive to these clutches is controlled by simultaneous actuation of the valve 42 controlling the fluid supply to the torque connecter through a reduced charging pressure valve 46, the fluid for the valve 42 being supplied from an independent circuit including a pump P. The friction plate clutch MC is modulatable by a centrifugally operated valve 51 controlling fluid supply to the clutch direct from the pump P. The output shaft from the torque connecter is coupled to a manually settable governor which is hydraulically coupled to the valves 46 and 51.

Abstract: 1,234,608. Adaptive equalizers. WESTERN ELECTRIC CO. Inc. 10 Sept., 1968 [11 Sept., 1967], No. 42932/68. Heading H4R. The adaptive transversal equalizer of Specification 1,161,342 is modified to operate with a partial response signalling system, i.e. with a signalling system in which each data bit involves a response at more than one sampling instant. Equalizers are described for a system using pulses, as shown in Fig. 1B, having equal response at two successive sampling instants, or, as shown in Fig. 2B, having equal but opposite response at sampling instants separated by two sampling intervals. Fig. 4 shows an equalizer, for use with the first of these systems, which is basically similar to that described in Specification 1,161,342 except for the correlation in the " exclusive-or " gates 49A-49E of the error signals stored in adjacent stages of the shift register 50, which has one more stage than the delay line 41, with an inhibit input on line 61 to prevent a counting pulse when the second slice on the slice and fold decoder 45 indicates a neutral or indeterminate signal sample. Decoder 45 is required since the effect of the signalling waveform is to cause a multilevel signal to be received, the slice and fold circuit providing, by mod 2 addition of the slice polarities, an indication of the signal error magnitude while the first slice indicates the signal polarity which is correlated with the error components in " exclusive-or " gates 47A-47E to control the up or down counting of counters 46. With isolated test pulses the signal polarity line and exclusive-or gates 47 may be dispensed with and the equalizer will adjust during test transmissions, the addition of these components, together with averaging of the error signals in counters 46, makes the system adaptive during signal transmission. The alternative form, Fig. 5 (not shown), for signal bits of the type shown in Fig. 2B, is identical to that shown in Fig. 4 except for a shift register with an additional stage and exclusive-or gates (79) which correlate signals from non-adjacent, spaced-bytwo, stages in the shift register, to take account of the signal having non-zero components spaced by two sampling intervals.

Resistive light reflecting 20 Á layer 24 comprises ferroelectric BaTiO 3  particles and SnO 2  semiconductive powders in urea resin, resistive light-opaque 10 Á layer 25 comprises carbon in epoxy resin for instance, pc 250 to 300 Á layer 26 may be CdS, CdSe, CdS-CdSe: Cu or Cl with epoxy resin for instance. Electrode 27 may be evaporated Ag or Al or a plurality of 10 to, 50 Á W wires at 300 to 500 Á pitch or a 200 to 500 Á mesh. Desirably the resistance in the thickness direction of layer 23 is greater than that of layers 24, 25 and the dark resistance of p.c. layer 26 > the thickness total resistance of layers 23, 24, 25. L 1  may be light or X-rays. D.C. voltage 31 incresaes the p.c. sensitivity and if layer 23 non- linearity coefficient is one, the sensitivity increases with input decrease, while a coefficient of three effects a varistor action.

Abstract: 1297518 Screening apparatus FMC CORP 19 Aug 1970 [20 Aug 1969] 41459/69 Heading B2H An paparatus for screening pea crops comprises a rotary screen drum 2 with beaters of the type described in patent Specification 961,272 and a number of nozzles 4 spaced along the length of the drum to direct jets of compressed air against the screen to prevent clogging of the screen apertures. The vines bearing the crop are fed into one end of the drum and the beaters break open the hulls to release the peas which pass through the screen apertures. The nozzles 4 are carried by a pipe 6 which is slowly reciprocated axially of the drum 2 to ensure that the whole of each screen section 3 is subjected to an adequate blast of fresh air. The pipe 6 is supported in slide bearings 8 each comprising three rollers 10. Reciprocatory motion is provided by a takeoff drive 12 acting through a worm gear 14 the output of which drives a chain 16 to one link of which is secured a pin 22 which engages a slot 20 in a trunnion 18 carried by the pipe. Instead of a mechanical drive a compressed air or electrical drive may be used. Compressed air is fed to the pipe 6 via conduits 24 and a flexible hose 26. The amount of air discharged through the nozzles remote from the inlet end of the drum is greater than that adjacent the inlet since the tendency for clogging increases from the inlet along the drum.
