Patent GB-276886-A (GB)
Title: Improvements in and connected with mechanisms for delivering printed products from printing machines
IPC: B65H29/06
Filed: 1927-02-16
Abstract: 276,886. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). Feb. 16, 1927. Delivery apparatus.-Printed products from high speed printing-machines are delivered in collected or uncollected form, and folded or unfolded, by mechanism involving an intermediate transfer cylinder 12 operating at the high speed of the press, and means such as a movable roller 29 for reducing the speed of the product to that of the delivery or folding mechanism. In the first form, Fig. 1, two products are collected on a cylinder 6, transferred by grippers 11 on a cylinder 9 to grippers 14 on cylinder 12, and taken by grippers 16 on a delivery cylinder 15 driven from cylinder 12 at a lower speed than this cylinder by means of gearing 18, 19. To control the products on cylinder 12 when the bending edges of the same are taken by grippers 16, rollers 29 mounted in cam-actuated oscillating arms 32 are lowered on to the product and press the same into contact with slip rings 27 freely mounted on boxes 22 carried on ball bearings 23 supported by studs 24 in spider arms 21, as shown in Fig. 5. The rollers 29 are driven at the lower speed, and prevent, the rear edges of the products from advancing too quickly. Instead of being delivered to a pile 17, the product may pass from cylinder 15 to a folder before final delivery. In one modification, the transfer cylinder 9 is dispensed with, and the roller 29 is mounted on the lower side of a cylinder, 12, which is of larger diameter than its collecting-cylinder. In another modification, Fig. 7, two transfer cylinders 45, 46, may be used for dealing with alternate uncollected products which may be folded by reciprocating blade folders A, B. The folder B and cylinder 46 may be put out of action and the cylinder 49 act as a collecting-cylinder. In another medication an arrangement of cylinders similar to those in Fig. 1 is employed, but the cylinder 9 can act as a rotary folder with jaws into which the product is folded by a jaw on cylinder 6. This machine can deal also with shorter products by arranging the first cylinder to act as a collecting-cylinder and dispensing with the folding-arrangement.

Filed: 1975-02-05
Abstract: 1452458 Particle analysis COULTER ELECTRONICS Ltd 5 Feb 1975 [6 Feb 1974] 4938/75 Heading G1N To avoid blocking the aperture when analyzing suspensions containing a range of particle sizes a large aperture 34 (e.g. 250 cc) is arranged beside a small aperture 32 (e.g. 50Á) at the top of the container. Measurements with the small aperture are not started until the pulse rate from the aperture 34 indicates that the larger particles are sinking from the upper layer of the suspension. An aperture 36 at a lower level in the container enables larger particles to be measured at the same time. Block Diagram Circuit Fig. 2 is for a large part self-explanatory and provides conventional delays  to allow steady flow before measurement, and volume detectors to stop measurement.  Control of the start of flow through the small aperture 32 is determined by pulses from the larger parallel aperture 34 which are applied to a threshold circuit 78 which is set for a particle (pulse) size which would block the small aperture. These larger pulses passing the threshold 78 discharge an integrator 80 (integrating an input voltage from battery). When there are insufficient large particle pulses to discharge the integrator its output rises to the level of threshold 86 to initiate flow through the small aperture 32.

Abstract: 976,763. Separating iron and copper. SOC. GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES SOGREAH, and COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 8, 1962 [Feb. 8, 1961], No. 4952/62. Heading C1A. [Also in Division B1] The apparatus permits the separation of iron and copper originally occurring together in, e.g. a hydrochloric medium by preferential precipitation of the iron as hydroxide, and filtration. During the precipitation and filtration stage, the solution containing iron and copper is introduced at 11 (valve j) whilst concentrated ammonium hydroxide is introduced at 12 (valve k). The iron precipitates as hydroxide while the copper remains in solution as a cuprammonium complex. At 5 (valve d), distilled water or dilute ammonium hydroxide is introduced to flush a granular filtering bed in a column A and elute the copper solution from the ferric hydroxide precipitate. The resulting liquids containing the copper are discharged at 6 (valve e). Periodically, valves d, e, j, k are closed and a carrying liquid is introduced at 3 and withdrawn at 4 in order to convey the filter bed up column A, so that the upper part of the bed, together with some precipitate, flows down a duct 7 into a compartment B. In B, washing liquid is introduced at 8 during the precipitation and filtration stage, passes up duct 7, and is discharged at 6. Periodically a valve g is opened to permit the washed mixture of filter bed grains and precipitate to pass into a compartment C. Into C, a solvent liquid capable of dissolving the precipitate (e.g. hydrochloric acid), is introduced at 13, and water at 9, the resulting solution being withdrawn at 10. During the early part of the precipitation and filtration stage, regenerated grains of filter material are transferred from compartment C to the bend A<SP>1</SP> through a valve a. In an example, column A has a height of 50 cms. and a diameter of 2.5 cms. and the rate of flow is 80 litres per hour per square decimetre. The filter material is glass balls of a diameter of 90 microns. The original solution contains 60 grams, each of copper and iron per litre. The copper and iron solutions produced each contain less than 0.1% of the other element. The conveying stages may last only a few seconds, whereas the precipitation and filtration stage may last one or several minutes.

[Class 100 (ii).] Transfers; transferring designs; etching.- Printing-plates are prepared from original drawings without the use of photography, by producing the original with a special ink on prepared paper, the original being then applied directly to the metal plate to form the printing- surface, which is subsequently grained, burnt, and etched. The original is prepared with a colour consisting of fatty, asphaltic, and alcoholic materials obtained by mixing a greasy autographic writing ink with turpentine oil asphalt, and pigment, a mixture of stearine, talc, and starch, a solution of wax in turpentine oil, and a solution of resin in alcohol being successively added ; finally, a mixture of powdered talc, asphalt and turpentine oil is added. The paper is of fine texture and absorbent and is coated with layers of gum arabic, cellulose lacquer, and gum arabic. The prepared picture is rubbed with a pad of cotton wool soaked in glycerine and the back is moistened with spirit, the picture being then pressed on to the zinc plate which has been rendered adhesive by a solution of resin in turpentine. The paper backing is then removed after moistening and the supporting layers for the picture are respectively removed by rubbing with water, dissolving in spirit and rinsing without rubbing with water. The plate is dried, washed with spirit again, dried and degreased and grained by placing for a short time in acetone. The grains of talc absorb the asphalt and grease of the colour and the spirit varnish is dissolved out, so that the colour is formed into a series of small dots. The plate is removed from the acetone, dried and burnt, and is then etched with dilute nitric acid. The picture is then removed with turpentine and, if necessary, the plate can be further etched with dilute nitric acid, and is finally deep etched.

Abstract: 1467540 Suspensions of maleamic acids RHONE-POULENC INDUSTRIES 6 Feb 1975 [7 Feb 1974] 5148/75 Heading C2C A process for the preparation of a suspension of a bis-maleamic acid comprises reacting maleic anhydride with a diprimary diamine in the presence of an organic diluent and a tertiary amine. The process is preferably carried out continuously. The diprimary diamines which can be employed in the process of the invention generally have the formula NH 2 -R-NH 2 , in which R represents a divalent aliphatic, cycloaliphatic, aromatic or heterocyclic radical which possesses at least two carbon atoms. The bis-maleamic acids prepared according to the invention have the formula in which R is as above. The anhydride and the diprimary diamine are advantageously introduced into the reaction zone in the form of two separate solutions, the solvents used for these two solutions being identical or different, but in the latter case, being miscible with one another. The presence of water generally between 0À2 to 10% by weight relative to the solvent can improve the yield. The molar ratio anhydride/diamine, characterizing the relative rate of addition of these two reagents, is advantageously 2À0 to 2À4.
