Title: Apparatus for automatically changing bobbins used in the manufacture of textile threads
IPC: B65H67/056
Filed: 1960-05-18
Abstract: 894,272. Winding yarns. COMPAGNIE DE SAINT-GOBAIN. May 18, 1960 [June 3, 1959], No. 17512/60. Addition to 882,128. Class 120(2) The apparatus according to the parent Specification for automatically changing the bobbins in the manufacture of textile strands is modified in that the bobbins are mounted on a common support frame and in that it has a mechanical system including a crankshaft to bring about automatically, at the moment the bobbins are changed, displacement of the bobbin support and the insertion of a member in the space separating the bobbins to allow the strand to pass from one bobbin to the other. The apparatus shown has two bobbins 3 and 3a, each with two sleeves 4, 4<SP>1</SP>, mounted on a carriage 1 which slides on frame 2. The bobbins are separately driven from motors 5, 5a. Strands 7, 7<SP>1</SP> are wound on the sleeves by guides 10, 10<SP>1</SP> driven by motor 11. A motor 12 drives disc 13 which through crank 14, lever 16<SP>1</SP> and rod 18 connected to member 20, moves the carriage 1 to transfer it from a position where winding is taking place on bobbin 3a to a position in which winding can take place on bobbin 3. This transfer takes place when winding on one pair of sleeves is completed For example when the sleeves on bobbin 3a are full, motor 12 is started and rotates disc 13 half a turn to displace frame I to the right. At the same time finger 23 pivoted at 19 on member 20, through rod 24, lever 25 and rod 27 causes disc 28 to enter the space between the bobbin 3 and 3a so that the strands 7, 7<SP>1</SP> can transfer to the sleeves on bobbin 3. At the same time motor 5 is started to rotate bobbin 3. When the carriage is stopped at the end of its run towards the right, roller 33 on arm 30 engages ramp 31 to cause retraction of disc 28 into bobbin 3a. After filling of bobbin 3 motor 12 is again started to move frame 1 to the left, disc 28 is again introduced into the space between the bobbin until such time as roller 32 on the other end of arm 30 engages ramp 29 to withdraw disc 28 into bobbin 3a, and so on.

Title: Improvements in processes of and apparatus for increasing the fluidity of material
IPC: B01F33/40
Filed: 1949-07-04
Abstract: 659,965. Mixing appliances. EVERY, C. E. (SMIDTH & CO., T. L.). July 4,1949, No. 17658. [Class 86] A method of increasing the fluidity of material such as cement consists in agitation in a container in which a stirrer is rotated initially with a small radius to sweep through a fraction of the material and is thereafter increased in radius to sweep through all the material. As shown in Fig. 1 a mixing tank 1 for finely divided solid material into which compressed air is supplied through inlets 3 contains a rotatably driven shaft 7 carrying stirring arms 13. The stirring arms 13 are pivoted to the shaft 7 and are displacable between substantially vertical and horizontal positions by means of rods 15 which are connected to pistons 18 acting in cylinder 19 secured to the shaft 7 exteriorly of the tank 1. In operation compressed air is first supplied to the solid material through the inlets 3 and after a brief interval the stirring mechanism is rotated with the arms in the lowermost position. Compressed air is then introduced into the cylinders 19 through a pipe 21 in a hollow upper end portion of the shaft 7 whereby the arms are progressively forced into the horizontal position. The inlets 3 may be constituted by nozzles or openings covered by porous material to divide the incoming air into fine streams. Such porous material may extend over a considerable part or even the whole of the bottom. Each ring of inlets 3 may be supplied through a separate valves can be opened in succession. In the admitted through the inner ring only and as the radius of the stirrer increases the valves can be opened in succession by the embodiments of Figs. 3 and 5 (not shown); each arm comprises two parts pivoted together on an axis parallel to the driving shaft, in Fig. 3 the parts being urged by spring means towards a straight radial line as the fluidity of the material increases and in Fig. 5 the parts being arranged so that when the shaft rotates in one direction the resistance of the material reduces the radial distance of the extremity whilst when the shaft rotates in the other direction the resistance tends to increase this distance.

Title: Improvements in and relating to resinous compositions
IPC: C08G63/20
Filed: 1932-06-23
Abstract: A resinous composition compatible with nitrocellulose and other cellulose esters is prepared by condensing a polyhydric alcohol and a polybasic acid in the presence of a dihydric alcohol, a dibasic aliphatic acid and the fatty acids derived from a drying or semi-drying oil.  In examples, glycerine, phthalic anhydride, ethylene glycol, succinic acid and the fatty acids of linseed oil, chinawood oil or cottonseed oil are condensed.  Other dihydric alcohols such as diethylene glycol, propylene glycol and tetramethylene glycol and other dibasic aliphatic acids such as malic, maleic, fumaric, glutaric, pimelic, suberic, azelaic and sebacic acids may be employed.  Fatty acids such as those derived from perilla or soya bean oils; polybasic resin forming acids other than phthalic, and polyhydric alcohols such as mannitol and pentaerythritol may be employed.  The resins are soluble in solvents such as alcohol - toluol, butanol - toluol - high flash naphtha, ethylene dichloride-toluol or pyroxylin solvents.  The resins may be rendered air-hardening by increasing the proportion of fatty acid or by adding an air-hardening alkyd resin.  In an example, a varnish containing a resin made according to example 4 is mixed with a varnish derived from an alkyd resin containing drying oil fatty acids such as those of linseed oil.  The resins may be used to impregnate leather and a coating for rubber and cloth to give a flexible oil and gasoline-proof material.ALSO:A resinous composition compatible with nitrocellulose and other cellulose esters is prepared by condensing a polyhydric alcohol and a polybasic acid in the presence of a dihydric alcohol, a dibasic aliphatic acid and the fatty acids derived from a drying or semidrying oil.

Title: Dispensing machine
IPC: B65B1/32
Filed: 1961-05-17
Abstract: 910,435. Weighing-apparatus. HESSER, MACHINENFABRIK-A.G., FR. May 17, 1961 [June 18, 1960], No. 17935/61, Class 143. A dispensing device 2, for dispensing flowable powdered or granular material, is provided with a regulating device and a device 4 for making up a premeasured quantity to target weight controlled by a weigher 3 in such a way that, if the density of the material varies, an increase or decrease of the volume dispensed is effected in dependence upon the deficiency from a predetermined weight of the material dispensed. A conveyer belt advances containers B intermittently and the device 2 first discharges into a container a quantity of material below the target weight. The actual weight is measured by the weigher 3, preferably a spring balance, which feeds impulses corresponding to the weight, or to the deficiency in weight, to control devices 6 and 7. The device 6 controls a reversible motor 15 which adjusts the dispensing volume of the device 2. Response to odd divergencies is prevented by a step-bystep switching device which only initiates an adjustment when a certain number of fixed actual weights which are below or above the lowest or highest limits have been recorded. The device 7 stores a number of impulses corresponding to the weight deficiency and, in accordance therewith, operates through an electromagnetic clutch 8, 9 and causes the feed screw 10 of the make-up device to perform a number of revolutions corresponding to the units of weight lacking. The revolutions of the feed screw 10 are counted photoelectrically and when the number of impulses corresponding to the stored value is reached the clutch 8, 9 is de-energized to terminate the auxiliary feed to the dispensing device. A viluatory shoot, controlled on a time basis, may be substituted for the feed screw. The make-up device may be positioned at the same station as the weigher 3 and the pre-dispensed quantity weighed as it is made up, the control device 7 then being dispensed with.
