IPC: B65B13/06
Filed: 1956-07-04
Abstract: 837,762. Package-binding machines. SEALLESS STRAPPING Ltd. May 29, 1957 [July 4, 1956], No. 20670/56. Class 94(1). In a binding machine of the type in which binding material is guided in a loop round the article to be bound by guides 10, Fig. 1, the guides have a section similar to that shown in Fig. 5A, so that the binding material S is normally retained in the guide by a shelf 11 from which it is withdrawn laterally when the binding material is tensioned by reversing the feed 18 Fig. 1. As the binding strip leaves the usual slot 15b it is guided out of the binding plane and beneath the upturned end 11a of the shelf 11 by a leaf spring 21, This leaf spring, and similar leaf springs 23, 24, Fig. 1, are deflected when the binding is tensioned so that the binding can escape from the shelf 11. The binding is also guided by a member 22, Fig. 3, and by a horizontal shelf 15d, Fig. 1, which ensures that the leading edge of the binding first passes. through a slot 19a in a gripper 19 and then, on its second pass, goes over the gripper to be secured so that the binding can be tensioned. The shelf 11 may be gapped. Specification 837,763 is referred to.

Abstract: 651,400. Winding yarn packages. HEATH & CO., Ltd., G. H., and BARNETT, J. Aug. 1, 1947, No. 20906. [Classes 120(ii) and 120(iii) A method of producing a yarn package which is substantially free from tension comprises the steps of mounting on a mandrel 2 having a longitudinal rib 4, a tubular bobbin 8 having a yarn-receiving surface and a resilient wall structure provided with a gap 10 extending longitudinally of the bobbin, the bobbin being positioned on the mandrel by sliding it thereon so that the rib 4 is located in the gap 10, the mandrel and bobbin being of such relative dimensions that the inner peripheral length of the bobbin 8 measured from the edge 11 to the edge 12 of the gap is just greater than the adjacent length of the mandrel measured from face to face of the rib 4, whereby tension in the yarn wound on the bobbin cannot tighten it against the periphery of the mandrel but can only produce pressure between the edges of the gap and the faces of the rib and wherein the width of the rib is such that it determines a gap during winding which is capable, upon closing, of substantially relieving all the tension in the yarn which has been wound on the bobbin in superposed layers, the wound package then being withdrawn from the mandrel and being subjected to treatment (e.g. steaming), which, will substantially release from the yarn the winding tension forced therein, the bobbin adjusting itself, through the medium of the wall gap, to the tensional force developed in the yarn mass during the winding operation. The mandrel 2 which may be provided with an end abutment flange 3, may also be tapered. The bobbin may be provided with small projections 9 or by a coating of plastic &c. to prevent slippage of yarn wound thereon.

Title: Regulator for winding on installations
IPC: D01H3/12
Filed: 1930-07-10
Abstract: 365,114. Mules. DETHIER, J., 7, Rue Auguste Dupont, Ensival, Belgium. July 10, 1930, No. 20974. Convention date, July 10, 1929. Void [Published under Sect. 91 of the Acts]. [Class 120 (ii).] In a regulator for the winding-on motion of a spinning mule two distinct connections between the winding-faller 5 and counter-faller 7, Fig. 4, and the quadrant nut are constituted by cams 5m, 5n, Fig. 6, displaceable as a function of the positions of the faller or counterfaller, acting upon levers 7v, 7w pivoting about arms 7r, 7s following the displacements of the counter-faller or faller, the ends of the levers supporting rollers 7t, 7u bearing against the cams, the other ends being connected by rods 7f, 8f to the system controlling the movement of the quadrant nut. The cam members are adjustable, the cam 5m being provided with a part 5p adjustably secured thereto by a bolt 5q in a slot 5r and which operates during the formation of the base of the cop, the part 5m<1> of constant radius acting during the formation of the cop body. The cam 5n is similarly adjustable over the whole of its extent. During an increase in the length of reserve an adjustable stop 7c on an arm 7b secured to the counterfaller 7 abuts against a lever 7d, fixed to an arm 5b rigid with the faller-shaft 5a, and to the rod 7f connected to a lever 7g pivoting about a fixed point 7k and, controlled by a spring 7p, operating a brake-band 7h round the pulley 7m. On a reduction in reserve a chain 8c fixed to the end of the lever 7b lifts a pulley 8d the shaft of which is secured to the rod 8f connected to a lever 8g pivoted at 8k and connected to a brake band 8h round the pulley 8m. The pulleys 7m, 8m move with the carriage and when the reserve has its normal value roll without sliding on the strands 9a, 9b of a chain supported on pulleys 9c, 9d. The decrease in length of reserve as the cop is wound is obtained automatically through the lever 7d, connected to the arm 5b, following the rise of the winding- faller and thereby reducing the distance between the stop 7c and lever 7d so that the action of the counter-faller is speeded up and prolonged. The position of the stop 7c and the length of the rod 7f are adjustable. A stop 5c on an arm 5d rigid on the shaft 5a abuts against an extension 5f on an arm 5h carrying the pulley 5k. When either of the pulleys 7m, 8m is braked it moves the chain 9a, 9b rotating the pulley 9c and thereby moving the quadrant nut 12c on the screw 12a, stops 9f, 9h, 10c, 10d, 11a, 11c being provided to control the action and to operate the clutch 12.

Abstract: 1,224,509. Shear blades. SCHLOEMANN A.G. 3 May, 1968 [11 May, 1967], No. 21093/68. Heading B3W. A shear blade assembly comprises an upper cutter block consisting of a bolster 3 and blade 2 and a lower cutter block consisting of a bolster 9 and blade 8, the bolsters being secured to their shear saddles 1 and 7 respectively by interengagement of spaced dovetail-shaped teeth 4, 10 on the bolsters and saddles, the gaps between the teeth being wider than the teeth and the height of the teeth on the upper and lower bolsters being the same. The cutter blocks can be removed from the saddles by displacing them a short distance longitudinally to disengage the teeth and moving them transversely to the longitudinal direction of the blade in either a horizontal or vertical direction. To remove the blocks carrier arms 11 on a travelling carriage 12 are engaged in slots (17), (18) (Fig. 4, not shown) in the lower bolster 9 and the front part of the carriage on which the arms 11 are mounted is moved transversely of the main body of the carriage. The carriage is then retracted until the teeth 10 are below the teeth 4 on the upper bolster. Rams (13) are raised (Fig. 2, not shown) to support the cutter block while the block is moved longitudinally, e.g. by hydraulic means, to disengage the teeth and the block is lifted clear of the saddle 1 by further raising of the rams 13 and finally lowered so that the teeth 4 engage in the teeth 10 of the lower block. The carriage is further retracted and a fresh pair of cutter blocks is mounted in the saddles by a reverse sequence of operations.

Title: Improvements in or relating to electric motor controllers
IPC: B21C1/30
Filed: 1944-10-30
Abstract: 606,655. Master control of D.C. motors. IGRANIC ELECTRIC CO., Ltd: Oct. 30, 1944, No. 21167. Convention date, Oct. 30, 1943. Addition to 571,669. [Class 38 (iii)] In a control circuit for a machine driven by a D.C. motor having means for automatic acceleration to selected running speeds and a load responsive relay with a winding in the motor armature circuit and a shunt winding connected to resistance regulating means to vary its current so that the relay can effect slow-down of the motor (as by increasing its field strength) at all running speeds immediately upon unloading of the machine, the regulating means is modified so that the relay is equally effective under all running conditions. Under load, the motor armature A (which may drive a metal draw bench) runs at a speed determined by the setting of the regulator 10 in the circuit of the motor field winding F2. If the motor becomes unloaded (e.g. if metal being drawn breaks during the operation), the motor speeds up, the current through its armature and relay winding 46a decreases and relay 46 drops out to cause switch 19 to close and short-circuit the field regulator 10, thereby checking further increase in motor speed. The armature current at which relay 46 drops out is determined by winding 46b connected in known manner between the adjusting arms of potentiometers 52 and 53, each of which is in a separate circuit across the supply. The arm of potentiometer 52 moves with field regulator 10 so that the setting of relay 46 is varied with the motor speed setting; potentiometer 53 is adjustable to compensate for variation in the no-load speed as the machine driven by the motor changes from a new or stiff condition to a run-in condition, and movement of the arm of potentiometer 53 also moves rheostat 52a to vary the total resistance in the circuit of potentiometer 52, whereby the relay 46 is caused to drop out immediately upon unloading of the motor irrespective of the running speed, the run-in condition of the draw bench or the size of the motor.

Patent GB-601472-A (GB)
Title: Improvements relating to the treatment of cyclic acetals for the production of glycols
IPC: C07C31/20
Filed: 1945-08-23
Abstract: Glycols are prepared by heating metadioxanes or dioxolanes with methanol or ethylene glycol, continuously removing the methylal or dioxolane formed by distillation, and fractionating the residue.  The reactants are refluxed, preferably in the presence of an acid-acting catalyst, reduced pressure being necessary when using ethylene glycol in order that the acetal formed may be removed below 90 DEG  C. Reaction temperatures of 50-90 DEG  C. are normally used when tertiary dioxanes or dioxolanes are treated.  With secondary or primary cyclic acetals, temperatures are normally 50-150 DEG  C. Small amounts of water may be present.  Catalysts for the conversion are acid-acting substances and halides of Group 2 or 4 elements, e.g. mineral and organic acids and acid salts, boron fluoride complexes, and compounds yielding acids with water, in amounts up to 20 per cent by weight of the acetal, and in concentrations of 85-100 per cent, preferably substantially anhydrous.  The molar ratio of added methanol to acetal should be at least 2 : 1 or of glycol at least 1 : 1.  This should be increased if azeotropes of the added compound and the acetal obtained are formed.  Reaction time is generally 1-30 hrs. After neutralization and filtration, the reaction product is distilled to recover the glycol.  The acyclic acetals formed may be hydrolysed or converted with olefins into meta dioxanes.  Thus, trimethethylene and methylal give 4,4,5-trimethyl meta-dioxane.  In a modified process, olefines or their unsaturated derivatives are condensed with aldehydes and the product treated according to the invention.  Cyclic acetals substituted by groups such as hydroxy, alkoxy or halogen yield corresponding substituted glycols.  Examples of starting materials include various mono- and poly-alkyl, phenyl methyl, cyclohexo, methyl methoxy, methyl ethoxyethyl, methyl chloro, methyl chlormethyl, chlorbenzo and methyl vinyl dioxanes, and alkyl dioxolanes.  Examples describe the preparation of 1,3-butanediol, its 2,3-dimethyl, 4-chlor-3-methyl and 2-chlor-3-methyl derivatives, and hydroxymethyl cyclohexanol from the appropriate substituted meta-dioxane by refluxing with methanol and sulphuric acid, stannic chloride or boron fluoride.
