Title: Improvements relating to machine tools
Inventor: BROWN GRAHAM MAURICE
IPC: B23F23/12
Filed: 1965-03-16
Abstract: 1,096,562. Mobbing. CHARLES CHURCHILL & CO. Ltd. May 4, 1966 [March 16, 1965], No. 11051/65. Heading B3K A machine tool having provision for copying, especially for crowning or tapering gears by hobbing, comprises a servo-controlled buffer unit 13 on the bed for co-operation with an adjustable anvil unit 5 on the work head 9, a transducer 69 and stylus 14 on one unit cooperating with a template 22 on the other, a cutting tool head 4 coupled to one unit, and means for causing relative movement between the anvil and bed after initial contact between the anvil and buffer has arrested conventional feed of the work-head along the tool bed. The head 9 is fed by a screw (53) against the stop 13 which is adjusted axially during cutting according to the movement of the tracer 14 on the template 22 to cause crowning of the gear. The head 9 carries a rack 21 to which the unit 5, carrying the anvil 20, is fastened by bolts 44. Fine adjustment of the anvil 20 is obtained by a setting knob 47, a dial 48 and a clamp 45. The template 22 consists of a half-round bar which can be adjusted angularly by a knob 54 to control the degree of crowning, and adjusted vertically by a cam-knob 58. The stylus 14 is carried on a transducer block (24) connected to the hob-slide by a tape (25) to move therewith. The stylus is biased outwardly by a spring and forms the core of the differential transformer 69. The stylus controls the speed of a D.C. motor. The motor drives a ball-nut through worm and spur gearing, the nut engaging a thread on the buffer 13. The motor also rotates a lubrication pump through a belt-drive. A main motor rotates the feed screw (53) to feed the work-head against the buffer 13 causing a worm in the drive to move axially to apply an electric brake, to disengage a feed clutch and to engage a clutch to cause the hob head to be fed vertically. The screw (53) can "float" against an hydraulic piston during movement of the buffer. In a modification, the stylus is mounted on the anvil and the template on the buffer unit. Additional friction may be provided in the drive to the buffer to ensure irreversibility. Two transducers may be provided

Title: Improvements in automatic feeding device for loose leaves particularly for tobacco leaves
IPC: A24C5/39
Filed: 1954-04-14
Abstract: 750,547. Feeding-devices. S.A.S.I.B.-SOC. PER AZIONI SCIPIONE INNOCENTIBOLOGNA. April 14, 1954 [April 24, 1953], No. 11076/54. Class 78 (1). An automatic feeding device for loose tobacco leaves comprises a substantially vertical hopper 1 having a swinging wall 3 and in which the swinging of said wall is controlled by a device 60 which is responsive to the resistance opposed by said material to compression, whereby the amount of swinging of the wall is automatically adjusted to the resistance opposed by said material to compression. As shown, wall 3 is caused to oscillate by the rotating cam 58 through follower 71, pivoted arm 57, prop 60 pivoted at 161 to lever 56 secured on shaft 103 of said wall. The whole system oscillates together during normal operation. If, however, wall 3 meets a greater resistance of leaves then its swing stops short, with the result that prop 60 in turn stops short and pivots downwards to touch arm 57 at a lower point. The system then continues to swing at smaller amplitude till the resistance of leaves diminishes, whereupon the wall and system oscillates once again with its original amplitude. The leaves thus fed are discharged by rollers 4, 6, 7.

Title: Improvements in or relating to roller grinding mills
IPC: B02C4/38
Filed: 1932-04-20
Abstract: 382,218. Adjusting bearings. MIAG MœHLENBAU UND INDUSTRIE AKT.- GES., 41, Rossstrasse, Brunswick, Germany. (Assignees of Moog, O. ; 9, Cellerstrasse, Brunswick, Germany.) April 20, 1932, No. 11278. Convention date, Dec. 17, 1931. Addition to 377,616. [Class 12 (i).] In the mechanism for controlling the pressure of grinding rollers the displacement of the piston or the rods of the pressure-imparting device for the movably mounted grinding rollers is limited by a movable stop controlled by the controlling device in the feed passage of the grist, the position of the stop determining the width of the gap between the grinding rollers or their pressure upon each other. As shown, a piston 6 is connected to the movably mounted roller by a piston-rod 54, a spring 64 tending to separate the rollers against the pressure of a fluid in the end 60 of a cylinder 8. The stroke of the piston 6 is limited by a stop 47 movable in the cylinder and which follows up the movement of a needle valve 13 actuated by the movement of a bell crank 21 connected to the controlling device in the feed passage of the grist. The valve 13 is actuated by a rod 44 and lever 45, and the end of the rod 44 bears against a plate 42 bolted to the shaft 37 of the bell crank. The plate 42 as arranged controls the valve 13 so that increase of feed increases the pressure on the rollers, whilst if arranged at an opposite inclination, the pressure of the rollers diminishes with increase of feed, and if arranged vertically the pressure remains constant whatever the feed. The stop 47 is provided with a stem 46 housing the valve 13 which is reduced in diameter at 49 and controls the flow of fluid to ports 51, 57, 63 in the stop. Pressure fluid is admitted at 61 and fills the space 60 under the piston, port 59 in the cylinder wall and ports 58, 57 in the stop 47. The space 53 on the other side of the piston communicates with exhaust passages 67, 68, 70 and with ports 52, 51 and space 50 in the stem 46. When the plate 42 tilts, the rod 44 and lever 45 push in the valve 13 which admits pressure fluid from the port 57 to port 63 and the stop is moved forwardly until communication with the port 57 is cut off. On the reverse movement of the plate 42 the valve 13 is withdrawn and port 63 is put to exhaust through ports 50, 51, 52, 53, 67, 70. The stop is then moved back by the piston 6 until the port 63 is covered and equal pressure maintained in the spaces 60, 62. The movement of the stop may be controlled by the position of the auxiliary motor, which varies the width of the gap of the feed valve or of the auxiliary motor which regulates the adjustment of the feed rollers.

Title: Preparation of alkyl sulfonates
Inventor: CLIPPINGER EVERETT
IPC: C07C303/32
Filed: 1959-04-03
Abstract: Alkyl sulphonates are prepared by the reaction of a bisulphite ion with a normal aliphatic 1-olefine containing 5-20 carbon atoms in the presence of water, an organic polar solvent and a reaction-initiating agent in a reaction zone, the organic solvent being present in an amount of from 75 to 200% volume based on the olefine and the bisulphite ion being added to the olefine-containing reaction mixture in the reaction zone at a rate such that the amount of free bisulphite ion in the reaction zone does not exceed about 25% mole of the olefine charged thereto, whereby the resulting reaction mixture consists of not more than two liquid phases.  Suitably, the olefine and 0.05 to 0.25 mole of bisulphite ion is introduced into the reaction zone and thereafter bisulphite ion is added at such a rate that 0.05-0.25 mole of free bisulphite ion per mole of olefine originally introduced is maintained in the zone until at least the stoichiometric amount of bisulphite required for the reaction has been reached.  The 1-olefines used may include other olefines and are preferably C5-20 olefines obtained on cracking petroleum wax, and desirably are first purified by means of silica gel.  Suitable organic solvents include methanol, ethanol, pyridine and hexanolamine.  The reactioninitiator may be molecular oxygen, an inorganic or organic peroxide, especially a peroxide in which the peroxy group is attached to at least one tertiary-carbon atom, or electron irradiation.  The bisulphite ion may be provided by ammonium, sodium, calcium or manganesium bisulphite in aqueous solution.  The ammonium bisulphite may be formed in situ by the simultaneous addition of aqueous NH3 and sulphur dioxide. The aqueous phase of the reaction mixture is preferably maintained at a pH of about 7.0 to 8.5, for example by addition of a base to the bisulphite solution.  Reaction may be effected at about 50 DEG -200 DEG C., desirably in the presence of a small amount of preformed sulphonate. The resulting alkyl sulphonates may be recovered by distilling off the polar solvent and water, if desired after de-oiling by extraction with a light hydrocarbon. Examples describe the sulphonation of dodecene-1, tetradecene-1, decene-1, hexadecene-1, octadecene-1 and mixtures of C11-13, C14-16 and C10-20 cracked wa olefines. Comparative experiments are described illustrating some of these sulphonations wherein either all the bisulphite is present at the beginning or is added at a faster rate than prescribed above.
