Abstract: 一种基于余数图像的数字水印嵌入和提取方法，将图像在空间域分块并利用混沌映射对各小块进行块内置乱，每小块中的载体图像数据被分解成“余数图像块”和“商图像块”，利用混沌序列对水印信息进行加密和直接序列扩频，将扩频后的水印信息嵌入到“余数图像块”中，对越界数据处理后将各“余数图像块”和对应“商图像块”组装，利用混沌映射进行块内反置乱并将各块组装后得到嵌入水印后的图像。水印提取时，按照水印嵌入时的顺序将图像分块并用混沌进行块内置乱，求得相应的“余数图像块”，然后用混沌映射生成的检测序列对“余数图像块”进行相关解调并进行门限判决，得到的加密水印用混沌映射解密后恢复出隐藏的水印信息。

A method of producing fabric from a yarn which is capable of being bulked includes the step of carrying out the bulking treatment as part of the fabricmaking process. As shown, yarn 13 is fed from creels 14 to the needles 12 of a tufting machine for insertion into a base fabric 11, via a heating zone 15 and a cooling zone 16. Zone 15 is preceded by yarn-feeding rollers 17, and zone 16 is followed by yarn-feeding rollers 18 the speed of which is less than that of the rollers 17 to compensate for the shrinkage resulting from the bulking treatment. It is stated that if the yarn is of wool the heating is by steam, and if of synthetic material the heating is dry. In a modification, the bulking treatment is applied, while the yarn is being inserted, by heating the tufting needles electrically. In the production of woven or knitted fabrics, the yarn may be bulked so it passes from the warp beam of a loom, or from the beam of a knitting machine.

Abstract: 1,228,030. Television. NATIONAL RESEARCH DEVELOPMENT CORP. 18 June, 1969 [19 June, 1968], No. 29130/68. Heading H4F. A radio-isotope scanning machine comprises a detector scanned across the field and means for providing a visual display of the detected radiation pattern, the density of the displayed image being proportional to the radiation level within those regions between lines of predetermined radiation level at which there are provided discontinuities in the density of the image. In a first embodiment, Fig. 1, a radiation detector 10 is scanned across the field of view and a CRT 3 is bodily scanned across a film 4 in synchronism. The output of the detector 10 is fed to a ratemeter 1 the output of which is a voltage proportional to the counting rate. This voltage is amplified and applied as EHT to the CRT. The brightness of the light spot produced on the CRT screen when a bright-up pulse is applied from pulse generator 5 via a potential divider to the CRT grid is proportional to the EHT voltage and thus to the radiation level. The output of the ratemeter 1 is also applied to a servomotor 14 which provides a proportional displacement of slide 13 carrying a plurality of earthed strips 15. A wiper 16 contacts the slide 13 and is arranged to short out the lower half of the potential divider 6, 7 at specific values of radiation level so that the image recorded on the film 4 has blank points at these values thus superimposing a series of contour lines. The scanning of the spot across the film may be performed by electronically scanning the CRT beam. In a second embodiment, Fig. 3 (not shown), the output of the ratemeter is connected to a servomotor which drives a wiper across a series of potentiometer tracks each of which is connected between two reference voltages. The voltage tapped off by the wiper is amplified and applied as EHT to the CRT and bright-up pulses are applied to the CRT grid. As the count rate increases, the density of the recorded image increases until the wiper moves on to the next potentiometer when the image density drops to zero and then starts to rise again. The resultant film image comprises a series of discontinuities forming contour lines between which the image density varies with the radiation level. In order to distinguish the radiation level range between contour lines each potentiometer may be fed from separate reference voltages, the corresponding reference voltage of each successive potentiometer being larger at higher radiation level ranges.

Headings BIB, B2E and B2L. [Also in Divisions C1 and F4] Solids are obtained from liquid mixtures comprising solid material and evaporable liquid, by forming a moving (e.g. fluidised) bed of particles in a chamber 16 by passing heated drying gases upwardly therethrough from plenum 26, pneumatically conveying particles from a lower chamber portion through a tube assembly 50 external to the chamber, to an upper chamber portion, spraying the particles in the assembly 50 with a liquid mixture from a nozzle 66 to coat the particles and drying the coated particles in chamber 16. The dried coated particles may be intermittently removed from the chamber through an air lock and control valve 40 and screen classified at 42. Air from inlet 90 may be passed through a perforated plate 64 surrounding the nozzle 66, to assist in conveying the particles through the assembly 50. The chamber 16 may have one or more than one tube assembly 50 associated therewith. The openings communicating the chamber 16 with each assembly 50 may be closed by slide gates 54. The spray nozzle 66 (Fig. 11) may comprise a central passage 80 for the liquid mixture and an annular passage 82 for gas to atomise the liquid.

Abstract: 1,228,420. Jacking attachments. COLORADO LEISURE PRODUCTS Inc. 29 June, 1968, No. 31186/68. Heading B7J. [Also in Division B8] A vehicle or other transportable body such as a camper C, Fig. 1, to be lifted for placement on an elevated surface, such as a truck bed (not shown) has raised lift surfaces L on opposite sides of the body and a lift jack apparatus comprising three lift jack units 10. A single lift jack 10 is mounted intermediately between the ends of the lighter side of the camper C and a pair of spaced jack units 10 on the other side, the spacing between these units being greater than the sum of the retracted lengths of the two units. Fig. 2 shows an exploded view of a jack unit 10, a lift bracket 16 and a storage angle bracket 60. The lift bracket 16 is attached to the camper C lift surface L (using extension brackets 52 if required). Each jack comprises a collapsible tripod 12 serving to support a screw jack assembly 14 consisting of a sleeve 30 terminating in an upper internally threaded end portion 31 having external ratchet teeth 32. Rotation of the tube 30 lifts an inner screw 33. The screw 33 is held against rotation by engagement of its upper terminal end 36 in a tube 46 welded in the bracket 16, the end 36 having a radial end surface complementary to the inner surface of the tube 46. An alternative form of jack, Fig. 5, comprises three telescoping lift sections: a stationary threaded sleeve 80; an outer rotatable collar 81 and a lift screw 83, which, upon rotation of the collar 81 causes simultaneous displacement of both the collar 81 and the lift screw 83 to obtain increased lift. When not in use the jacks may be stored endto end along the side wall S using the bracket 60 and a bracket 65<SP>1</SP>, Figs. 13, 14, or under the lift surface L using the bracket 60 and a bracket 72, Fig. 17.

Printed sheets 1 leaving an impression cylinder 2 in a multi-unit press are transferred to a further impression cylinder 32 by a transfer cylinder which includes associated suction head and gripper pairs 4, 5 which under the influence of a cam action swing inwards in unison to transfer the trailing edge of a sheet on cylinder 2 on to the surface of the transfer cylinder. The transfer operation is aided by flexible guiding strips 7 which project from the transfer cylinder and hold the sheet 1 during the transfer.

Abstract: 1,231,341. 4,4<SP>1</SP> - Bipyridyl. BIOGAL GYOGYSZERGYAR. 15 May, 1969 [23 May, 1968], No. 24887/69. Heading C2C. 4,4<SP>1</SP> - Bipyridyl is prepared by reacting pyridine, an aliphatic acid anhydride and zinc in the presence of an inorganic acid or BF 3 , and oxidizing the N,N<SP>1</SP>-diacyl-tetrahydro-4,4<SP>1</SP>- bipyridyl so obtained to 4,4<SP>1</SP>-bipyridyl in the presence of a dehydrogenating catalyst, using a chlorinated hydrocarbon solvent. Preferably an alkyl acetate is present in the reaction mixture. A suitable dehydrogenating catalyst is palladium or charcoal. Quaternary dialkyl- 4,4<SP>1</SP>-bipyridylium salts are obtained by reacting the bipyridyl prepared as above with a dialkyl sulphate.
