Patent GB-681196-A (GB)
Title: Manufacture of acetyl-acetone
IPC: C07C45/45
Filed: 1949-12-23
Abstract: Acetyl acetone is produced by the reaction of acetone, ethylacetate and an alkali alcoholate at a raised temperature, in which acetone, preferably together with ethyl acetate, is gradually added to a mixture of an alkali alcoholate and ethyl acetate, and, as soon as the temperature reaches the boiling point the alcohol is distilled together with acetone so that a mixture of alcohol, ethyl acetate and a small quantity of acetone passes over, while an alkali acetylacetone and, when present, an alkali ethyl aceto-acetate remains behind.  The reaction is preferably commenced at a temperature of 30-50 DEG  C. with the introduction of part of the acetone.  Only small amounts of by-products such as mesityl oxide, acetyl-mesityl oxide and the like are formed.  The process may be conducted under superatmospheric pressure and/or a solvent may be added.  Methyl acetate may be used instead of ethyl acetate.  In the examples, a mixture of acetone and ethyl acetate was gradually added to a mixture of sodium alcoholate and ethyl acetate to give a mixture of sodium acetyl-acetone and sodium ethyl aceto-acetate.

IPC: B60R22/38
Filed: 1962-08-29
Abstract: 1,069,401. Safety harness. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. Nov. 29, 1962 [Aug. 29, 1962], No. 33192/62. Heading A3V. [Also in Division F2] A device for preventing extension of a safety belt comprises first and second means between which the belt passes and actuating means over which the belt passes and which at a predetermined tension in the belt causes the first and second means to grip the belt between them. As shown a safety belt 6 coming from e.g. a storage reel, passes around a rotatable roller 3 carried by arms 4 pivoted at 5 in sideplates 1 and biased by a spring 7 away from a fixed bar 2 around which the belt also passes. When a predetermined force is exerted on the portion A of the belt leading to the wearer the arms 4 pivot towards the bar 2 which engages a recess 9 in the roller 3 with the belt gripped between them. The roller 3 may be replaced by a non-rotatable knurled bar and the storage reel by a weight on an extension spring attached to the end of the belt. In a modification, Fig. 3 not shown, a spring reel (10) is mounted between the sideplates (1) with the end of the spring (11) secured to one of the arms (4) biasing the roller (3) away from the gripping position so that as the belt is withdrawn from the reel thus increasing the tension in the belt, the pull on the arm (4) is also increased, thus ensuring that the gripping means always become operative at approximatetly the same acceleration of the belt relative to the reel. In a further modification, (Fig. 4 not shown) in which the reel is mounted nearer to the bar (2) than to the roller (3) the arms (4) are pivoted to the sideplates intermediate their ends and the end of the spring (22) is attached to the free end of one of the arms (4).

Title: Method of manufacturing seamless hollow bodies
IPC: B21C1/24
Filed: 1953-11-30
Abstract: 744,447. Making hollow-wave and tubes. STAHL-UND, ROHRENWERK REISHOLZ GES. Nov. 30, 1953 [Nov. 29, 1952], No. 33205/53. Classes 83 (2) and 83 (4). Drawing: cupping.-A method of manufacturing seamless hollow metal bodies and tubes comprises hot drawing a hollow blank having a closed end through a deforming tool, or tools, with the aid of a mandrel and exerting radial pressure on the work by the deforming tool or tools, the mandrel being moved axially and alternately in opposite directions within the region of the said radial pressure and an axial force being exerted on the part of the work which emerges from the tool or tools. The mandrel 2 may consist of a tubular body 6 removably mounted on a rod 3 (Fig. 3). During the first stage of the operation the mandrel contacts the bottom of the hollow blank 1 and pushes it through the die ring 4 after which tongs exert a pull on the blank whilst the mandrel is reciprocated. Alternatively, a push rod 10 axially guided within the mandrel (Fig. 5) produces the necessary axial force or such force may be exerted by placing a reciprocable ring 11 (Fig. 6) around the end of the blank emerging from the die said ring being provided with hydraulic pistons 12 for gripping the blank. Either the mandrel or the ring or both are driven, the non-driven member being freely movable and being carried along by the friction between the ring the blank and the mandrel. Further, the axial force may be provided by an hydraulic medium introduced in the space between the mandrel and the bottom of the blank through a bore passing through the mandrel and the mandrel rod. Also, the mandrel may be lengthened and the blank shrunk on to the mandrel by suddenly cooling a part of the drawn blank so that the mandrel itself provides the axial force.

Filed: 1956-11-01
Abstract: 842,411. Regulating switches. GENERAL ELECTRIC CO. Ltd. Nov. 1, 1957 [Nov. 1, 1956], No. 33377/56. Class 38 (5). An on-load tap selector switch and an auxiliary selector switch are driven in sequence by a mechanism which produces the tapchanging operations described in Specification 842,412. Rotation of motor-driven shaft 33 clockwise causes an arm 40 to turn a Geneva wheel 41, said wheel carrying a double-armed crank 42 which turns a further Geneva wheel 43 on the shaft of the auxiliary selectors. At the same time an arm 34 on the shaft 33 is rotated and after 90 degrees abuts a member 35 which is biased to the Fig. 2 position by a spring 36. Movement of arm 34 through a further 90 degrees carries member 35 into engagement with an arm 38 loosely mounted on the shaft 33. The arm 38 is now carried round by the arm 34 and member 35 until after a further 90 degrees, Fig. 5, the spring 36 is fully stretched. A slight further rotation enables the spring to move the arm 38 rapidly in advance of the arm 34 and during this rapid movement the arm 38 drives a maltese cross gear 39 connected to the main selector. Continued movement of the parts 34, 35 occurs until they return to the Fig. 2 position, the part 38 then falling by gravity to its Fig. 2 position. This sequence of operations is reversed if the shaft is driven counter-clockwise.

Title: Improved manufacture of body colours for coating leather
IPC: C14C11/00
Filed: 1930-11-06
Abstract: In the preparation of coloured coating compositions for leather, a vinyl compound is mixed with another film-forming substance such as a cellulose ester, or a second vinyl compound. For example, polyvinyl acetate is dissolved in a solvent and a colour such as lithol scarlet or Sudan black is added, and the resulting mixture is incorporated with a solution of cellulose nitrate or a mixture of cellulose nitrates of differing degrees of nitration.  The composition is applied to leather or goatskin by spraying or pouring, and when dry the coating is glazed, polished, or grained.  Solvents such as butyl acetate or alcohol, ethyl acetate or methyl cyclohexanone, together with diluents such as ethyl alcohol, or toluol may be used, and plasticizers such as triphenyl or tricresyl phosphate, butyl oxalate, castor or linseed oil, or dibutyl phthalate, are added.  In a modification, the coating composition consists of a mixture of vinyl compounds only of differing viscosity.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the treatment of the dry coloured coating with a transparent coating of the composition, omitting the pigment. This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specifications 15271/14, 285,049, 308,658, 313,569, 315,228, 318,549, 339,271, and 345,521, [all in Class 95, Paints &c.].

[Class 17 (i)] A pounding-up or hammering machine adjustable for pounding-up shoe uppers of various kinds and sizes and different thicknesses of upper material and for dealing with both right and left shoes has a rotary hammering drum 11, a side hammer 15, and a feeding device for the workcarrying last 9, under control of spring means 20, 55 respectively to adjust the feed device at right angles to the surface of the hammering drum and also toward and from the side hammer. The last 9 is clamped on an adjustable holder 8 supported on a column 7 enclosed in a casing 27 mounted for universal movement about its base. A cam path 2 on a disc mounted on a driving shaft 1 driven by a motor controlled by an operator by a pedal 65 moves, by a roller 17, a bell-crank lever 16 pivoted at 21. A fork 18 at one end of this bell-crank lever engages a pin 23 on a shaft 24, upper end of which is connected by a spherical joint 26 to column 7 which is guided in a bearing 28 in the casing 27. The lever 16 is moved against the control of the spring 20, tension of which is adjustable by a screw 22 so that, on rotation of the shaft 1, the column 7 and last 9 are movable vertically up and down against the action of the spring 20. Similarly, a cam path 4 on the shaft 1 controls, through a roller 37, bell-crank lever 38, joint 40 and link 41 pivoted to casing 27 at joint 43, the forward and rearward movement of the last relatively to the side hammer 15 against the action of the spring 55, tension of which is adjustable by screw 56. A cam path 5 and roller 48 control, through the linkage shown in Fig. 2, movement of the casing 27 and column 7 from left to right and right to left by an amount dependent on the position of a pin 53 which connects levers 46, 51. The link 41 passes through a spherical joint 42 located in a frame 44 slidable in a recess in a head 45 at one end of lever 46 pivoted upon 47. Rotary motion is imparted to the column 7 by a rack 33 which is reciprocated in guides 32 by a link 31 from a cam path 3 by a roller 30 on which engages a toothed sector pivoted on a pin 35 (not shown), which carries a second toothed sector 36 also mounted on the pin 35 and which gears with a spur wheel 29 on the column 7 to rotate it.
