Patent GB-943171-A (GB)
Title: Preparation of graft copolymers
IPC: D01F6/18
Filed: 1962-02-09
Abstract: A graft copolymer-containing spinnable solution is made by dissolving a protein an unsaturated monomeric material containing a predominant proportion of acrylonitrile in an aqueous solution containing at least 40% by weight of zinc chloride, and then polymerizing the dissolved monomeric material.  Proteins specified are silk fibroin, yeast, corn, soya bean and peanut proteins, casein, zein, gelatin and synthetic protein, e.g. a copolypeptide of glutanric acid and lysine. If desired, the protein may be cyanoethylated with acrylonitrile prior to the graft polymerization.  The monomeric material may be acrylonitrile, alone, or in admixture with methyl acrylate, methyl methacrylate, vinyl acetate, styrene and vinyl chloride. The polymerization may be initiated by means of hydrogen peroxide or a persulphate, or a mixture of a persulphate or a chlorate and sodium sulphite.  Proteins of the above types are cyanoethylated by treatment with acrylonitrile in an alkaline aqueous medium in the absence of a polymerization catalyst.  The cyanoethylated protein may be recovered from the reaction medium by acidifying it.  The cyanoethylation of soya bean protein is described.  Solutions of proteins in concentrated aqueous zinc chloride are stabilized against the formation of a flock phase by the addition thereto of an unsaturated monomer, e.g. vinyl acetate, acrylic acid, acrylamide, acrylonitrile, and methyl acrylate and methacrylate.

Abstract: 1,059,042. Wet separation of granular materials. CUDGEN RUTILE (NO. 1) PTY. Ltd. Feb. 5, 1965 [Feb. 6, 1964], No. 5157/65. Heading B2H. An apparatus for the wet separation of mineral sands from a pulp containing mineral and silicon sands comprises a series of sluice units each having a forwardly and downwardly inclined bottom 17, side walls 22, 23 or 22a, 23 forwardly convergent to an outlet passage, an undercut opening 26 in the bottom 17 at or near to the outlet passage, and means for adjustably varying the angle of convergence of the side walls towards the outlet passage. As shown, five series each of four laterally aligned sluice units are formed in an upgrading tray 15 having a bottom 17 and side walls 18 all made of water-resistant plywood, the bottom 17 of the tray providing a common bottom for all the units. A number of superimposed trays 15 are mounted in a tilted frame 10-13, Fig. 1 (not shown). The side wall 22 or 22a of each unit is fixed and is made of water-resistant plywood. The side wall 23 consisting of a strip of water-resistant plywood with a strip 24 of neoprene, Fig. 3 (not shown), extending from its bottom, is pivotable at 25 to vary the angle of convergence of the side walls. All the side walls 23 of corresponding sluice units of all the trays 15 may be simultaneously adjusted angularly by means of side shift bars 30 secured to the side walls 23 and rigidly secured at their ends to a pair of actuating bars 34, Fig. 1 (not shown), laterally slidable in the channels 10 and top members 12 of the frame. Each of the bars 34 at one side of the frame is moved through links 38 and lever arms 39, Fig. 4 (not shown) by means of a shaft 40 which may be turned in one direction or the other through a double lever 49 by means of a screw 42 having a squared end 44 for engagement by a suitable tool. The undercut opening 26 of each sluice unit is a lateral slot in the tray bottom 17 which has a P.V.C. strip secured to its rear edge and extending below the level of the tray bottom. The undercut openings communicate via shuts 29 under each tray with launders 28 secured in rectangular holes in the tray bottoms. In use, the pulp is fed, from a tank via hoses 50 and distributors 19, simultaneously to all the trays 15 and flows through the sluice units of the rear or upper series. During its travel over the bottom of each sluice unit the pulp tends to stratify, the denser mineral sands forming a large part of the bottom stratum and the lighter silicon sands forming an upper stratum. At the outlet from the sluice unit, the lower stratum flows through the opening 26 and the upper strata overshoot this opening and spread out over the bottom of the next sluice unit ahead in line where the process is repeated, and so on until the tailings are discharged at the front of the tray into a common chute 51.

Class 40(3) In a double beam spectrophotometer arrangement having a light switching cycle which is divided into three equal preiods; a first period in which light is prevented from reaching a measuring photo-cell which then produces a signal which is a function of its dark current and any extraneous light in the system, a second period in which light is directed to the photo-cell via a reference cell and a third period in which the light is directed to the photo-cell via a specimen cell, a signal processing arrangement in which the output signals of the photo-cell are referred to a true zero signal level before application to a comparison circuit. The light wavelength required is selected from a source 2 by monochromotor 6. The light beam leaves the monochromotor via its exit slit 5 and passes to a mirror assembly comprising fixed mirrors 10 and 12 and mirrors 11 and 13 which are rotated by shafts 15 and 16. The assembly either absorbs light or directs it to photo-cell 14 via reference cell 17 or specimen cell 18 in the previously stated sequence. The output of the photo-cell is amplified 20 and passed to a switching arrangement operated by shafts 15 and 16. During the first period switches 26 and 27 are closed and switches 30 and 31 are opened, during the second period switches 27 and 31 are closed and switches 26 and 30 are opened and during the third period switches 26 and 30 are closed and 27 and 31 are opened. Switch 27 is closed during the first period when the dark current signal is produced and the second period when the reference cell signal is produced, condenser 25 and resistance 29 convert these signals to a signal train of equal positive and negative voltage-excursions which are referred to ground as a reference potential and which are a function of the difference between the dark current signal and the reference cell signal. Switch 31 is closed during the positive excursions of this signal train and the positive signal is applied to an integrating circuit 33, 35. Similarly a signal which is a function of the difference between the dark current signal and the specimen signal is produced across condenser 34. The voltages across condensers 34, 35 are applied to a recording potentiometer circuit including servo-amplifier 38 and servomotor 40 and a chart 41 records a comparison of the light transmission through reference and specimen cells.

Filed: 1916-04-13
Abstract: 100,815. Elliott, R. C., and Lanston Monotype Corporation. April 13, 1916. Single-type composing and casting machines.- To enable a number of successive castings to be made from the same matrix in machines such as are described in Specification 8633/99, the feed of the record-strip is suspended for a predetermined number of cycles of the machine by means controlled by a special signal in the strip. In the form described, the locking-pawl A<3> of the feedmechanism described in Specifications 8982/01 and 4263/02 is held down to prevent the feed by a notched disk B which co-operates with a projection A<5> on the pawl. A notch in the disk is normally over the projection A<5> to permit the feed to take place. The disk can be rotated by means of a ratchet-wheel and a pawl B<2>, which is carried by a lever B<3> and is normally disengaged from the ratchet-wheel by the action of a lever C and a fixed stop C<1>. When a character is to be repeated, a rod D, which is advanced by the special signal, acts through the lever C to engage the pawl B<2> with the ratchet-wheel and rotate the disk B. The feed-mechanism is thereby locked until another notch in the disk comes over the projection A<5>.

Patent GB-797356-A (GB)
Title: Improvements in or relating to secondary radar systems
Inventor: HARRIS KENNYTH ERNEST
IPC: H04N5/12
Filed: 1955-02-24
Abstract: 797,356. Radar. COSSOR, Ltd., A. C. Feb. 20, 1956 [Feb. 24, 1955], No. 5542/55. Class 40 (7). The invention relates to the prevention of erroneous indications due to the presence of side lobes in interrogator-responder radar systems where the interrogator aerial system is arranged to produce a sharp single beam. In accordance with the invention two intercalated series of interrogating pulses are radiated, the pulses of one train being of a different intensity to those of the other. For example, a stable pulse generator 10 may be arranged to supply frequency dividers 11 and 12 so that odd-numbered pulses modulate high-power transmitter 13 and even-numbered pulses modulate low-power transmitter 14. The transmitter outputs are combined and taken through a T/R switch 15 to the directive aerial 16. The interrogator receiver 17 receives signals from the aerial through the T/R switch and its output is applied to two gated amplifiers 20 and 21. The output from the two amplifiers is commoned and fed to a suitable indicator, for example a cathode-ray tube. The gate in amplifier 20 is opened for a time allowing the admission of return signals from ranges of from 0-10 miles following the transmission of pulses of lower intensity. The gate in amplifier 21 is opened for a period allowing admission of return signals from ranges of from 10 miles up to the maximum following the pulse transmissions of higher intensity. It is here assumed that above 10 miles responses due to side-lobes in the interrogating pattern will not occur and clearly the point of changeover can be adjusted to suit a particular set of circumstances. The pulses applied to open amplifier 20 can be obtained from pulse generator 22 comprising a multivibrator triggered from the output of divider 12. The gate pulses for amplifier 21 can likewise be obtained by using the output from divider 11 to trigger a delay multivibrator followed by a differentiator, the second pulse in the output of which triggers a second multivibrator forming the gate pulse (Fig. 2, not shown). More than two interlaced trains of pulses may be used, and a correspondingly greater number of different range gates provided after the receiver. The pulses in each train may either be single pulses or groups of pulses. When the low-power transmitter is effective at ranges below 10 miles it is possible that the aerial side lobes may produce responses from ranges, say, below 1 mile. If this is objectionable the gating pulse from generator 22 can be delayed and shortened to cover the range 1-10 miles. Alternatively, or additionally, an omnidirectionally radiated control pulse may be transmitted a few microseconds before each low power pulse as described in Specification 734,588.
