Title: Improvements in or relating to the measuring of running webs
IPC: G01B5/04
Filed: 1934-04-25
Abstract: 440,404. Measuring fabrics. MENSCHNER, J., 36, Doebelner Strasse, Rosswein, Saxony, Germany. April 25, 1934, No. 12470. [Class 42 (ii)] Both sides of a fabric are measured as by a drum 3, Fig. 1, and a measuring band 2, or two measurements are taken of the same side of the fabric as it passes over rollers 27, 28, Fig. 11, of different diameters, and the correct length is calculated therefrom. When the correct length is the arithmetic mean of the two measurements the counter 13 may be driven from both the measuring rollers or bands through ordinary differential gearing, but when the correct length 1<0>, Fig. 5, is not the mean of the two measurements 1<1> and 1<2> but differs therefrom in the ratio a : b, the two halves of the differential gearing are connected by gear wheels 26, 25, Fig. 7 of the same ratio, the wheels 26, 25 being mounted in the cage 24, mounted on the shaft 12 of the counter 13. When two measurements are taken of the same side of the fabric 1, Fig. 11, as it passes over rollers 27, 28 of diameter ratio 3: 1, the correct length is the measurement given by the larger roller plus half the difference between the two measurements, or the measurement given by. the smaller roller plus one and a half times said difference. In this case the counter 13, Fig. 12, is not driven directly from the cage of the differential but by a wheel 45 twice the diameter of the wheel 44 as shown. The fabric may not contact with a measuring drum but only with bands 2, 2a which themselves engage the measuring drums 6, 3a with the same surfaces as they engage the fabric. Specification 431,888 is referred to.

Title: Modified water-soluble polyamides and substrates treated therewith
Inventor: GOLDBERG ALAN AUGUST
IPC: D06M15/595
Filed: 1965-03-24
Abstract: 1,135,645. Epoxidized polyamides. PRECISION PROCESSES (TEXTILES) Ltd. 23 March, 1966 [24 March, 1965], No. 12567/65. Heading C3R. [Also in Division D1] A water soluble condensation resin is produced by reacting a linear water soluble polyamide containing free secondary amino groups with a linear polyoxyalkylene compound having terminal groups which react with secondary amino groups so that 5-50% of these groups react and then treating the product with epichlorohydrin. The polyamide may be derived from a polyalkylene polyamine or a mixture of an alkylene diamine and at least 20% polyalkylene polyamine and 0À4-0À6 mole per primary amino group of a C 3-10  alkane dicarboxylic acid. The polyalkylene polyamine may have 2-8 alkylene groups which may have pendant alkyl groups. The dicarboxylic acid may be replaced by its chloride, bromide or ester. The polyoxyalkylene compound may be derived from a polyethylene glycol or propylene glycol of M.W. 100-2500 or a compound of formula where R and R<SP>1</SP> are H or hydrocarbon radicals free from olefinic or acetylenic unsaturation, e.g. methyl, phenyl or benzyl, and n is at least 3. The terminal groups may be halide introduced by halogenation, e.g. with SO 2 Cl 2 , PCl 5  or PBr 5 , or by reaction with an epihalohydrin, haloformyl introduced by oxidation, e.g. with HNO 3  or an alkali metal metavanadate, an halogenation or haloformate introduced by reaction with phosgene. Where the terminal group is halogen it may be reacted with the polyamide at elevated temperature in the presence of an acid acceptor. Where it is chloroformate it may be reacted at room temperature in the presence of an acid acceptor. In either case a diluent may be used. The product may be reacted at 40-90‹ C. with 1À0-1À5 moles of epichlorohydrin per free secondary amino group. This product may be quaternized with 30-50% of the theoretical amount of quaternizing agent to stabilize it. Alternatively it may be stabilized by formation of a 20-25% aqueous solution of pH 5-6. The product may be used as an antistatic agent or to prevent shrinking of woollen textiles. In this case an anion large enough to be trapped in the polymer lattice may be introduced. Anions specified are alkyl sulphate ions of at least 10 carbon atoms, alkyl benzyl sulphate ions of at least 13 carbon atoms, N-alkyl and N-alkenyl taurine anions, dinaphthylmethane disulphonate and dinaphthalene disulphonate ions. In Example (1) a polyamide of adipic acid and diethylene triamine is reacted with halogenated polyethylene glycol in the presence of KOH and polyethylene glycol as solvent. The product is treated with epichlorohydrin. In Example (4) the polyamide of Example (1) is reacted with polyethylene glycol which has been oxidized and halogenated in polyethylene glycol as solvent, the product being treated with epichlorohydrin. In Example (5), the product of Example (1) is treated with disodium dinaphthalene disulphonate.

Title: Television cameras
IPC: H04N9/04
Filed: 1975-03-26
Abstract: 1501016 Television SONY CORP 26 March 1975 [29 March 1974 25 April 1974] 12699/75 Heading H4F A solid state colour television camera comprises two charge coupled devices (CCDs) 10A and 10B, Fig. 2, on to which images of a viewed scene 14 are focused by optics 15 via colour filters 18A and 18B respectively. Each CCD consists of a first array 20A, Fig. 1, of light sensitive locations 1 1-  1 ,..., 1 m-n , and a second identical storage array 30A shielded from incident light into which charges from array 20A are transferred for intermediate storage and from which the charge is transferred line by line into a shift register 40A for subsequent sequential output as a picture signal component. Each location consists of a pair of photosensing cells 2 from which the charge is clocked out by antiphasal clocks # 1  and # 2 . The two CCDs 10A and 10B, Fig. 3, are disposed such that the image on one is shifted by half the horizontal element pitch relative to that on the other. The colour filters 18A and 18B, Fig. 5, each consist of a series of alternate strips, equal in width to the vertical element pitch of the CCDs, of components passing yellow (Yl) and white (W) light to CCD, 10A and cyan (Cy) and green (G) light to CCD, 10B. The resultant frequency spectra of the derived signals are shown in Figs. 6 and 7. Figs. 7A and 7B illustrate the frequency spectra of the outputs of arrays 10A and 10B respectively, from the odd lines therein so that they are derived from incident light passing through the yellow and cyan filters respectively. These outputs are low pass filtered 19a and 19b before being combined by an adder stage 21. Here, due to the antiphase nature resulting from the relative array shift of half the horizontal element pitch, the green components of the modulated carrier fc cancel, giving the spectra of Fig. 6A as output for odd lines, of adder 21, that for even lines is shown in Fig. 6B. Filter 26, Fig. 2, passes the D.C. components Fig. 6C which constitute a luminance signal that is subtracted from the appropriately delayed 29 signals from adder 21 to give the side band component containing the colour information Figs. 6D and 6E. The side band components are applied through a one line delay 33, adder 34 and subtractor 35 producing the red and blue components for demodulation 36, 37 and matrixing 27, from which an NTSC type signal is obtained. Thus the camera of the present invention causes a phase relationship between the side band components of the modulated carrier fc, S SBAO , S SBBO  which leads to cancellation of the "folded error" occurring in the hatched portions of the spectra of Fig. 7 due to the overlap of the D.C. and side band components, obviating the requirement of a higher carrier frequency which since it is a direct function of the line sampling rate leads to a corresponding reduction in the acceptable size of the CCDs. In another embodiment Figs. 8-13 (not shown) three CCDs are employed shifted by one third of the horizontal element pitch relative to each other providing improved definition.

Title: Improvements in and relating to preparations for cultivating yeast
IPC: C12N1/16
Filed: 1923-05-14
Abstract: 197,935. Pollak, A. May 16, 1922, [Convention date]. Yeast.-A culture-medium for yeast is prepared from material containing proteins, such as ground legumes, soya meal, oil cake, cereal germs, bran grains, flesh meal, &c. by treatment first with strong acids and then with weak acids, enzymes, &c., so as to produce the different amino-acids and other decomposition-products of protein required by the yeast. The material is first boiled with a strong acid, such as sulphuric or hydrochloric acid, until the proteins are dissolved. The acids are then diluted, or part neutralized, or wholly neutralized, and replaced by weaker acids or enzymes &c. Ammonia may be used for neutralizing the acid, or sulphuric acid may be neutralized with lime, or calcium phosphate or lactate, thereby replacing it by lactic or phosphoric acid. Hydrochloric acid may be neutralized with carbamide. Soluble albumens, enzymes, vitamines, organic phosphorus compounds, &c. may be extracted before the operation and returned to the final product. After the acid has been neutralized, sugar may be added and lactic acid fermentation produced.

Title: Improvements in or relating to yarn tensioning devices
IPC: D04B15/44
Filed: 1955-05-05
Abstract: 833,425. Knitting-machines. REYMESCOLE, B. T. R. May 3, 1956 [May 5, 1955], No. 13063/55. Class 74 (2). A yarn tensioning device comprises a compensator arm 28, 31 secured to a balance wheel 21 pivotally mounted in a cup 13 containing oil to a level to cover the wheel 21. The spindle 20 of the wheel 21 carries a coil spring 25 which urges the arm 28, 31 to a position in which yarn from a bobbin is guided by eyes 29, 30 into a position on which it makes maximum contact with a cylindrical drag member 18 before passing through a stationary guide eye 33 to the knitting-machine. As the tension of the yarn from the supply bobbin increases or decreases the arm 28, 31 is moved to cause the yarn to decrease or increase its length of contact with the drag member 18 and thereby maintain the tension in the yarn from the device to the machine substantially constant. The position of the guide 33 can be adjusted by moving its supporting bracket 16. The effect of the spring 25 can be varied by moving a clamp 26 securing the end of the spring. In the case of straight-bar knitting machines a spring-loaded arm is provided which engages the yarn extending from the device to the carrier of the machine at the end of each traverse and takes up the slack in the yarn and simultaneously holds the arm 28, 31 in a position which corresponds to the tension in the yarn extending from the device, so that on commencement of the next carrier traverse the yarn does not have an increased tension imposed which otherwise would be caused by the arm 28, 31 taking up the slack and increasing the length of contact of the yarn with the drag member 18. The drag member may be suitably scored to increase the drag effect.

Title: Process for intensifying silver photographic images
IPC: G03C5/42
Filed: 1953-05-11
Abstract: 725,737. Intensifying photographic images. DU PONT DE NEMOURS & CO., E. I. May 11, 1953 [July 17, 1952], No. 13106/63. Class 98 (2). Photographic silver images are intensified by treatment with an aqueous solution containing ferricyanide ions and ions of lead, zinc, mercury, copper, nickel, cobalt or cadmium, followed by toning in an aqueous solution containing chromate or dichromate ions and at least one polyvalent metal cation which forms a waterinsoluble ferrocyanide. Alkali metal or ammonium ferricyanides may be employed in the first solution and the second solution may also contain ferricyanide. The preferred cation for the first solution is lead, and this may be supplied by lead nitrate, acetate, bromide, chloride, formate, lactate or citrate. The first solution may also contain an acid such as acetic, formic, hydrochloric, citric, nitric, glycollic or lactic acids, and also an alkali metal or ammonium halide. Buffering salts such as alkali metal acetates, formates, lactates and citrates may be added to keep the pH in the range 1-6. The preferred cations for the second solution are ferric and uranyl, but cations such as Va++, Cu<SP>++</SP>, Ag<SP>+</SP>, Co<SP>++</SP>, Mm<SP>++</SP>, Hg<SP>++</SP>, or Ni++ may also be used, and the chromate or dichromate may be potassium dichromate, sodium and ammonium chromates and dichromates or mixtures of these. For colour work, separation negatives may be obtained from a tripack comprising a very low coating weight blue record film in front of a bipack of green and red record films. After processing, the front film is stripped and intensified according to the invention. In an example, a colour film comprises a cellulose triacetate base, a red-sensitive, greeninsensitive emulsion containing a water-soluble yellow filter dye, a stripping layer composed of a mixture of 88 per cent hydrolysed and 99 per cent hydrolysed polyvinyl acetate, a greensensitive emulsion, a stripping layer of 88 per cent hydrolysed polyvinyl acetate and a low coating weight blue-sensitive emulsion. The yellow filter dye may be 4: 4<SP>1</SP>-methyl-bis- [1 - (p - sulphophenyl) - 3 - methyl - pyrazolone - 5] or 4: 4<SP>1</SP> - methenyl - bis - [1 - (p - carboxy - phenyl) - 3 - methyl - pyrazolone - 5]. After exposure and wetting with water, the blue and green record films are transferred to separate blank films and all three records processed. The weak silver image in the blue record layer is bleached in an aqueous solution comprising acetic acid, lead nitrate, potassium ferricyanide and potassium bromide and then toned in an aqueous solution of ferric nitrate, potassium dichromate and potassium ferricyanide. To neutralize somewhat the green colour of the intensified image, the final wash water may contain a dye such as Anthraquinone Rubine R cone. (C.I. 1091), Pontacyl Carmine 6B Extra cone. (C.I. 57) or Pontacyl Rubine Extra cone. (C.I. 179). Specifications 444,773, 552,230 and 629,631 and U.S.A. Specifications 2,274,782, 2,415,442 and 2,448,552 are referred to.

Title: Improvements in or relating to tipping bodies for vehicles
IPC: B60P1/14
Filed: 1923-05-16
Abstract: 197,941. Fortini, A. May 17, 1922, [Convention date]. Tipping-wagons.-In mechanism for operating the tipping bodies of motor or other vehicles of the type in which one end of the body is elevated by means of ropes, chains, &c. engaging with pulleys &c. mounted on the ends of stanchions or pillars which are normally arranged vertically, or substantially so, and! are pivoted on the chassis of the vehicle so that they incline as the end of the body is elevated, an automatic pawl mechanism is provided which prevents the body from returning to its normal position if the chains &c. should break when the body is being elevated, and the tipping mechanism is driven direct from a worm on the propeller shaft of the engine. As shown, the tipping body is hinged at its rear end to the chassis and connected at parts v, Fig. 3, at its front end to chains &c. i passing over grooved pulleys t on a shaft s, connecting the upper ends of single or double pillars q, r, Fig. 2, pivoted at their lower ends u to pivoted supports o, the other ends of the chains being connected to winding drums h, k fixed to shaft e mounted in the supports o, one of which ends in a lever p. To the drum h is secured a brake disc n for preventing too rapid descent of the body when lowered and a gear wheel g, and loose on the shaft e is a similar gear wheel d integral with a boss c and a worm. wheel b adapted to gear with a worm a on the driving shaft of the vehicle motor. A gear wheel l, Fig. 4, on a lever support m normally gears with the wheels d, g. When the body is to be tipped, the driver moves the lever p and supports o to cause the wheel b to gear with the worm a thus rotating the drums h, k and tightening the chains i, so that the shaft e and supports o are held thereby in their displaced position. Further rotation of the drums winds up the chains and raises the body in contact with the pillars which tilt to allow for the movement of the body, grooved wheels on the parts v contacting with the pillars to minimize friction. Pawls x pivoted on the parts v and acted upon by springs y are adapted to engage ratchet teeth w on the pillars, or bars secured thereto, to check descent of the body. When the body is raised to the desired extent, it acts on the end of a draw-rod z connected to the lever support m and disengages the gear wheel l from the wheels d, g so that rotation of the winding drums stops, and since the body is now supported by the engagement of the pawls x with the teeth w on the pillars, the supports o are rocked on their pivots under the weight of the parts and the wheel b is withdrawn from the worm a. When the body is lowered, it strikes the end of the lever support m and replaces it in its normal position. The body door may be opened automatically when the body is raised to the desired height, or it may be opened to an adjustable extent and the contents distributed with the vehicle in motion.
