Title: New methylene compounds of lithium and magnesium and the production thereof
IPC: C08F10/00
Filed: 1956-04-06
Abstract: The invention comprises lithium methylene and magnesium methylene which are prepared by heating lithium methyl and magnesium dimethyl respectively in the absence of air.  The heating may be carried out in a vacuum or an argon atmosphere or in an indifferent solvent such as a high-boiling Diesel oil which has previously been distilled over sodium.  Benzene, hexane, cyclohexane and decahydronaphthalene may also be used if the process is carried out in an autoclave.  The products may be used as catalysts for the polymerization of olefines. In examples, lithium methyl is heated to 240 DEG  C. in the presence of argon in a metal bath, and magnesium dimethyl suspended in a Fischer-Tropsch Diesel oil which has been liberated from olefines by repeated hydrogenation and freed from hydroxyl compounds by distillation with sodium, is heated in an argon atmosphere to 250-255 DEG  C.

Title: Improvements in or relating to processes of and machines for grinding work pieces with a plurality of unequal diameters
IPC: B24B5/18
Filed: 1929-04-09
Abstract: 309,412. Cincinnati Grinders. Inc., (Assignees of Booth, C.). April 9, 1928, [Convention date]. Centreless grinding ; guide and rests ; wheels. In grinding work-pieces having portions of different diameters, such as drills, in a centreless grinding machine, each work-piece is supported outside the grinding throat while one portion is being ground, and this ground portion is then supported outside the throat of a second machine while the previously supported portion is being ground concentrically with the first formed portion, the same portion of the work being used for determining the axis of rotation in each grinding operation. The machine comprises a grinding wheel 12 and a regulating wheel 17 mounted on a transversely movable slide 14 which carries a base 18 carrying the work-supporting blade 19, Figs. 2 and 3, in the grinding throat and the work-rest 23 outside the throat. The blade has an inclined upper face so as to maintain the work 24 in contact with the regulating wheel by gravity and the rest has a surface 26 inclined at the same angle as the blade and a surface 27 approximately parallel to the portion of the regulating wheel which encounters the work. The rest 23 is vertically adjustable by slots 29 and screws 28 on two lugs 21, 22, projecting vertically from a member 20 which is transversely adjustable on the base 18 by a screw 31 and is locked by a screw 30. In operation, the rest 23 is adjusted to compensate for the difference in diameter of the two portions of the work and the grinding is effected in the barrel portion 25, the wheels being conical so as to produce longitudinal clearance on the drill. The inclination of the surfaces of the rest 23 is such that lateral oscillation of the work is prevented and the work will rise parallel to itself should it be raised in the grinding throat due to irregularities on its surface encountering the regulating wheel. The work is then removed to a similar machine in which the previously ground portion 25, Fig. 7, is supported in a sleeve 33 and the shank 24 is acted upon by a grinding wheel 12 whilst being rotated by a regulating wheel 17. The regulating wheel has a projecting rib 34 and the work support in the throat has a similar projection so as to engage that part of the work which was previously engaged by the rest 23. The machine employed for the second grinding operation is described in Specification 309,413.
Patent GB-582087-A (GB)
Title: Improvements in laminated glass sheets
IPC: C03C27/12
Filed: 1942-08-07
Abstract: Laminated sheets are made from two or more lamin , at least one of which is a glass sheet, united by a film comprising a material obtained by interpolymerizing ethylene with at least one ester or ketone which contains the grouping <FORM:0582087/IV/1> where A is hydrogen, halogen or a monovalent hydrocarbon radical and B is an aliphatic radical containing a carbon atom joined to an oxygen atom by a double bond and which is separated from the CH2=C< group by not more than one carbon or oxygen chain atom.  Suitable esters or ketones are vinyl esters, e.g. vinyl acetate and substituted vinyl acetates, acrylic esters and related substances such as methyl methacrylate, vinyl ethyl ketone and two or more is obtained from ethylene and vinyl acetate in molar ratio between 7 : 1 and 20 : 1. The laminated sheets may be prepared by casting from a solution of interpolymer on to a glass sheet or by slicing from a preformed cake of interpolymer, followed by assembly of the lamin  under heat and pressure. Alternatively, the interpolymer may be united to the lamin by means of an adhesive.  Suitable adhesives are diphenylolpropane formaldehyde resins, solutions of pyroxylin and diamyl-phenol and complexes of silicic acid with trialkyl phosphates, e.g. tributyl phosphate.  Although for safety-glass, transparent interlayers are essential, opaque material may be made by using an opaque interlayer obtained by incorporating in the interpolymer pigments, extenders, fillers, resins or organic cellulose derivatives.  Materials other than glass which may be used together with glass for producing laminated sheets include organic polymers such as methyl methacrylate and polystyrene, and cellulose derivatives, i.e. the acetate.  In examples, laminated glass sheets are made (see Group VIII). Specifications 481,804 and 497,643 are referred to.

Title: Improvements in or relating to torque limiters
IPC: F16H35/10
Filed: 1953-04-24
Abstract: 726,009. Toothed gearing. SOC. D'EQUIPEMENT MINIER. April 24, 1953 [April 30, 1952], No. 11445/53. Class 80 (1) [Also in Group XXXIV] A torque limiting device comprises an epicyclic train connected between driving and driven shafts, the reaction member being held by a braking device but being automatically released on the transmitted torque exceeding a predetermined value. The epicyclic train comprises two sun gears 1, 2 on the driving and driven shafts 5, 7 respectively and stepped planet pinions 3, 4 engaging the sun gears 1, 2 carried by a cage member 9. A drum 10 mounted upon the cage 9 is adapted to be engaged and held by a brake band 11. One end 12 of the band 11 is attached to a compression spring 13 abutting a fixed part 14 whilst the other end 15 is adapted to be fixed in relation to a fixed point 16 by means of an overcentre linkage 17, 18. The link 18 is formed by two side plates 18<SP>1</SP>, 18" with a handle 20 and is pivoted about the fixed point 16. In the position shown the brake band is applied and the drum 10 held from rotation so that shaft 5 drives shaft 7 through the gears 1, 3, 4, 2. If the torque transmitted exceeds a predetermined value the spring 13 will give to release the end 12 of the brake band. This will result in the drum 10 slipping and a cam projection 26" thereon engaging a projecting pin on the link 18. This will cause the link 18 to tilt about point 16 and move the link 17 over-centre to release the end 15 of the brake band so that the drum 10 is completely freed and the drive from shaft 5 to shaft 7 interrupted. To reset the device after the excessive torque demand is finished the pin 19 can be retracted by a pin 31 thereon and the handle 20 depressed to gradually apply the brake band again and move the link 17 back over-centre to a locking position. The cam projection 26" will move from under the pin 19 which can be reset together with handle 20 so that the mechanism assumes the original position as shown.
