Title: A new improved method of crowning gears and apparatus for carrying such method into practice
IPC: B23F19/00
Filed: 1941-01-21
Abstract: 543,730. Gear-cutting. NATIONAL BROACH & MACHINE CO. Jan. 21, 1941, No. 815. Convention date, Jan. 22, 1940. [Class 83 (iii)] Milling-cutters.-The teeth of a gear G are crowned in a finishing operation by means of an intermeshing conjugate gear-like tool C which is rotated with the work gear in crossed axes relationship while being moved relatively to the gear about the common normal 11 to the axes of the gear and tool or about an axis parallel to said common normal. In some cases relative translation in the direction of arrow 12 may also be imparted. If only the ends of the teeth are to be modified the initial mesh in mid-position is a loose one so that oscillation through a certain distance has no effect. In this case the centre part of the teeth may be finished in a separate shaving operation. In another modification, Fig. 4, the finishing of the ends only of the teeth is effected by a cutter C<SP>1</SP> having spaced elements 13, 14. The helical alignment of the teeth of the parts 13, 14 may be ensured by mounting the members on an arbor on helical splines. Specification 503,952 is referred to.

Title: Process for the production of neutral mixed esters of orthophosphoric acid
Inventor: KOEBNER ADOLPH
IPC: C07F9/12
Filed: 1952-01-10
Abstract: The invention comprises a process for the production of a neutral orthophosphate ester (other than the compounds forming the subject of Specifications 734,764, 734,765, 734,766 and 734,767) by the reaction of one mol. of phosphorus oxychloride with one equivalent of a non-aromatic primary alcohol and either two equivalents of an aromatic phenolic compound or one equivalent of each of two different aromatic phenolic compounds, wherein one equivalent of the aromatic phenolic compound (or the less reactive of the two different aromatic compounds) is progressively caused to react in proportion as it is used up with the phosphorus oxychloride at a temperature of 70 DEG to 90 DEG  C., preferably in the presence of a metallic catalyst, a second equivalent of the aromatic phenolic compound (or one equivalent of the second, more reactive aromatic phenolic compound) is caused to react in the same manner, and the unpurified product is added progressively in proportion as it is used up in the reaction to a refluxing mixture of a hydrocarbon solvent and one equivalent of the non-aromatic alcohol, or to one equivalent of the non-aromatic alcohol refluxing alone under reduced pressure.  The process may be applied to the production of compounds of the formula <FORM:0734768/IV (b)/1> in which R is a primary alkyl radical containing 6 to 12 carbon atoms or an alkoxy-ethyl radical in which the alkyl substituent contains 4 to 12 carbon atoms or the tetrahydrofurfuryl radical and R1 and R2 each represent the phenyl or cresyl radical, or R1 is a chlorinated phenyl radical and R2 is the phenyl radical or a chlorinated phenyl radical.  The invention also comprises compounds of the above general formula in which R is the tetrahydrofurfuryl radical R1 is a chlorinated phenyl radical and R2 is either the phenyl radical or a chlorinated phenyl radical.  The preferred catalyst is metallic magnesium.  In example (1) two molecular proportions are added to 1 molecular proportion of phosphorus oxychloride heated to 70 DEG  C. at such a rate that the added phenol reacts immediately.  The reaction product is then gradually added to a refluxing mixture of 2-ethylhexyl alcohol and benzene to give diphenyl-2-ethylhexyl phosphate.  Similarly prepared are (2) di-(o-chlorphenyl)-2-ethylhexylphosphate; (3) di-(2 : 4-dichlorophenyl)-alkyl phosphate, in which the alkyl group is the residue introduced by the reaction of mixed primary alcohols with a mean molecular weight of 125 containing C7, C8 and C9 chains derived from an olefin fraction by the Oxo-process.  In example (4) phenyl o-chlorphenyl tetrahydrofurfuryl phosphate is prepared by reacting one mol. phosphorus oxychloride successively with one mol. each of o-chlorophenol, phenol, and tetrahydrofurfuryl alcohol according to the procedure outlined above.  Specifications 300,044, 328,963 and 330,228, [all in Class 2 (iii)], also are referred to.

Title: Device for producing semi-finished tubes of constant inner diameter with thinned ends
IPC: B21B17/14
Filed: 1974-01-08
Abstract: 1421673 Rolling tubes G I GULYAEV, J N NEZNAMOV A I NECHIPORENKO V Y OSTRENKO P I KUTSENKO V K KURILENKO I V ERMOLOV A I CHEKMAREV V G VORONKO I P BOIKO V R MAMONTOV J I PUSTOVOICHENKO G M VOLOVIK V G ZAKHARENKO and VÀP PASCHENKO 8 Jan 1974 00866/74 Heading B3M [Also in Divisions G2-G3] A control system for a rolling mill stand producing tubes of constant internal diameter with thinned ends includes a drive arrangement for displacing the rolls to increase the clearance between the rolls when rolling the front end of the tube and decrease the clearance when rolling the rear end. A typical installation is shown in Fig. 1 where ingots are brought to a piercing mill 2 from a furnace 1 and after piercing are delivered by an inclined grate to a longitudinal mill 3 which includes a receiving trough 27, see Fig. 2. The mill rolls have round grooves 5, 51 and the upper roll 5 can be displaced by hydraulic ram arrangement 15 to vary the clearance between the rolls. Rollers 28 are provided for returning the tube to trough 27 on an idle pass when rolls 5 are moved apart and the tube can then be rotated through 90 degrees for a further pass to be made. The hydraulic fluid flow to rams 15 is controlled by electromagnetic valves 41, 42 energized from the drive engaging unit 44 shown in Fig. 5. The mill stand is provided with a tube end sensor 43, roll position sensors 50, 51 and a load sensor 52 which provide signals for use in the control system. The tube end sensor, as shown, includes two sensing elements 54, 55 which enables the front and rear ends of the tube to be identified. Additionally the length of the thinned end portion can be controlled by unit 46 which controls the speed of displacement of the roll 5 and unit 48 provides a delay. A clock pulse generator 56 is used to provide a length calibration and a pass number sensor 53 also is provided. In operation the rolls are driven to the minimum clearance position and retained there until the tube end enters the roll which is predetermined from sensor 43 and delay 45 and confirmed by load sensor 52 when the rolls are driven apart to roll a taper on the end of the tube. The cylindrical part of the tube is rolled with the rolls at the required spacing until the rear end of the tube is sensed when, after a delay, the rolls are driven to the minimum clearance position to provide the rear end taper. After two passes the tube moves to the oblique roll mill 6 which has the clearance between the rolls varied in a similar manner to that of mill 3. A roller conveyer 12 transfers the tube to reheating furnace 7 and stretch reducing mill 8.

Title: Improvements in moulds for continuous casting
Inventor: ISMAY WALTER NICHOLAS
IPC: B22D11/041
Filed: 1961-01-09
Abstract: 924,758. Making casting-moulds; continuous casting. YORKSHIRE IMPERIAL METALS Ltd. Jan. 3, 1962 [Jan. 9, 1961], No. 892/61. Classes 83 (1) and 83 (2). A method of making a mould for continuous casting comprises assembling a graphite liner in a metal tube and drawing down the assembly to give the metal tube a compressive fit on the graphite liner. The graphite body 10 may be solid or hollow and is machined externally. It is positioned in a cleaned tube 11 and drawn through a die 13. If the liner is hollow it may also be expanded into the tube by a mandrel. The deformation is such that the two parts make a compression fit even when at the elevated temperatures which occur during casting. After drawing, the graphite is machined to size internally and the assembly is cut into the desired lengths.

Filed: 1963-01-08
Abstract: 1,026,462. Internal shoe-drum brakes. BENDIX CORPORATION. Jan. 8, 1963, No. 9C6/63. Heading F2E. [Also in Division E2] A brake actuating cam-shaft 44 is supported in a resilient bearing member 48 which has a spherical outer surface and is pivotally mounted in a complementary spherical recess in a resilient guide ring 52 held in a bracket 34 attached to the brake supporting member 14. The member 48 and ring 52 are preferably made of plastics material such as " Teflon " (Registered Trade Mark) or nylon. The T-section brake shoes 10, 12 lined with friction material 13, Fig. 1 (not shown), are mounted on guide projections 16, 18 on the support 14 and are interconnected at their lower ends by a floating adjustable strut 20 and a tension spring 22. Each shoe has an elongated opening 38 which receives a boss 36 secured to the support 14 by an anchor pin 24, 26 and the shoes are actuated by rotation of a rectangular cam 42 integral with the shaft 44. A return spring 40 is connected between each shoe and its corresponding anchor pin. If the brake drum is rotating in the clockwise direction the actuation of the brake causes the shoe 10 to cease to bear against its boss 36 and the braking torque is transmitted through the shoe 12 to the other boss: if the rotation is counterclockwise the shoe 10 transmits the torque. The angular movement of the shaft 44 caused by movement of the shoes is accommodated by movement of the bearing member 48 in the guide ring 52.

Title: Improvements relating to control systems for rotating elements
Inventor: ASBURY ALLAN
IPC: H02P5/50
Filed: 1949-01-13
Abstract: 664,509. Automatic speed control systems. ENGLISH ELECTRIC CO., Ltd. Jan. 6, 1950 [Jan. 13, 1949], No. 939/49. Class 38 (iv) A system for controlling the relative speeds of a sequence of motors 20, 40, 60, comprises, for each of the motors except the motor 20, a speed control arranged to operate in a corrective sense in response to any deviation from an adjustable predetermined relationship between the values of a first electrical quantity which varies in accordance with speed variations of its associated motor and a second electrical quantity which varies in accordance with speed variations of the next preceding motor. Each of the D.C. motors 20, 40, 60 drives a tachometer generator 21, 41, 61 feeding transformers 22, 42, 62 and the first electrical quantity is derived from transformer secondaries 22a, 42a, 62a and is fed to the right-hand grids of double triodes 63, 23, 43. The second electrical quantity is derived from secondaries 22b, 42b, 62b and is fed to the left-hand grids of triodes 23, 43 and the valve associated with a further motor, if any, the voltage fed to the left-hand triode of the valve 63 being an adjustable reference voltage derived from a potentiometer 67. Each of the valves 23, 43 63 acts as a comparison device for the voltages fed to its grids so that any deviations of speed relationship between motors 20 and 40, 40 and 60, or in the case of motor 20 from a predetermined value, fixed in each case by adjustment of associated potentiometers, e.g. 26, 29, will result in an unbalance of the currents in the load resistors, e.g. 27, 30, of the valves. assuming that the speed relationship between motor 20 and 40 is upset then a voltage will be fed through filter 32, D.C. amplifier 33, thyratron apparatus 34, to control field winding 40a of the motor 40. Similar apparatus is provided for each valve. The speed of the motor 20 is thereby controlled absolutely and the speeds of the other motors are controlled relative to the motors preceding them. The armatures of the motors are supplied from a constant voltage generator 75 under the control of a potentiometer 76. In a modification each motor may be supplied from a separate generator and the potentiometer 76 arranged to vary the excitation of all the generators simultaneously. The control field windings supplied from the thyratron apparatus may then be on the generators or the motors. According to the Provisional Specification the absolute speed may alternatively be maintained constant by comparing the speed of one of the motors with a further tachogenerator driven by a master motor.
