Title: Improvements in or relating to extreme pressure lubricants and process of preparing the same
Filed: 1939-04-27
Abstract: 528,096. Extreme pressure lubricants. STEVENS, A. H. (Armour & Co.). April 27, 1939, No. 12637. [Class 91] A lubricating composition adapted to withstand extreme pressures consists of a lubricant, such as a petroleum hydrocarbon oil or grease, or a lubricating aralkyl ketone such as xylylalkyl ketone, and a small amount of one or more alkyl thioamides, preferably with at least 6 carbon atoms in the alkyl radicle. Specified examples are undecyl, tridecyl, pentadecyl and heptadecyl thioamides. In an example, 6 parts by weight of heptadecyl thioamide are added to 100 parts by weight of Pennsylvania bright stock lubricating oil. The oil alone can carry a load of onlv 800 lb. as tested in the Farille-La Vally machine. After addition of the thioamide, a load of 4500 lb. can be sustained. U.S.A. Specification 2,110,288 is referred to as describing the Farille-La Vally oil-testing machine.

Title: Improvements in mounting optical lenses
IPC: G03B41/08
Filed: 1930-04-25
Abstract: 349,254. Lens mounts. JOHN, W. E., 10, Charnwood Avenue, Merton Park, London. April 25, 1930, No. 12740. [Class 97 (i).] In the production of a lens-containing cell having a bearing surface which is a surface of revolution about the optical axis of the lens, the cell with the lens fixed therein is mounted so as to rotate about a fixed axis and is adjusted so as to bring the optical axis into coincidence with the fixed axis, a bearing surface which is a surface of revolution about the fi x e d axis being then machined on the cell. The cell 9 is shown as mounted in a carrier 2 of the kind described in Specification 319,302, [Class 97 (i), Optical systems &c.], having an external cylindrical surface 3 and provided with flanges 4 which constrain the carrier against axial movement in the guide in which it is mounted. The carrier is formed with an internal bore 6, coaxial with the surface 3, to receive the lens cell 9, and with a shoulder 7 accurately spaced with regard to the flanges 4. To produce the desired bearing surface on the cell 9, it is chucked, with the lens in position, on a hollow spindle lathe 13, on the axis of which is an illuminated mark 15, a telescope 19 being provided to form, in conjunction with the lens 10, an image of the mark on a screen 17 which bears a mark 18 at its point of intersection with the lathe axis 14. The screen is observed through a microscope 20 and the cell 9 is adjusted until the image of the mark 15 remains stationary and coincides with the mark 18 as the chuck is rotated. The cell is then machined so as accurately to fit the bore 6. The chuck can also be adjusted by means 21 to bring the image of the mark 15 into focus on the screen 17, and when so adjusted the end of the cell is machined off by means of a tool 24 at a fixed distance from the screen. The correct focusing position of the cell within the carrier 2 is thus assured, the machined end of the cell being pressed into contact with the shoulder 7 bv a nut 25.

Abstract: 592,341. Severing adhesive tapes. COW & GATE, Ltd., and CHARLES, G. K. May 22, 1945, No. 12763. [Class 73] [Also in Group VIII] A tape-severing device for use in a can-taping machine, e.g., such as is described in Specification 574,156, consists of an electrical resistance wire 8 extending across the end of an arm 2 between insulated spring metal blades 6, 7. A low voltage supply is connected to the wire 8 so that it is heated to incandescence. A needle 9 is inserted in the arm 2 adjacent the wire 8 so that its point projects beyond the wire, and the tape is held on the needle until it is severed. The arm 2 is supported on a bar 1 having a slot 21 for the reception of a clamping screw 11 by which the device is attached to a stationary part of the machine. The arm 2 is fulcrummed on a bolt 3 at the end of the bar 1. A bracket 14 fixed to the bar 1 has two adjusting screws 4, 15 which form stops to limit the pivotal movement of the arm 2.

Title: 4-substituted-phenylacrylic acids and derivatives thereof
Inventor: ARMITAGE BERNARD JOHN
IPC: C07C57/42
Filed: 1963-04-01
Abstract: The invention comprises compounds of formula <FORM:1026921/C2/1> wherein R represents a C2-C5 alkyl or C2-C4 alkenyl group, a C3-C7 cycloalkyl group optionally substituted by a methyl group in the 1-position, a C2-C3 alkoxy, an allyloxy or a phenoxy group, and X represents COOR1 wherein R1 is hydrogen or a C1- 4 alkyl group, COOH.B where B is a non-toxic organic base, COOM where M is a single equivalent of a non-toxic metallic cation or the ammonium ion, or CONH2.  The free acids may be prepared by (1) reacting an a -keto-phenylacetic acid with a Grignard reagent to give an a -hydroxy-a -phenyl-propionic acid which is then dehydrated by fusion and distillation, (2) conversion of an a -bromo-styrene to a Grignard reagent and reaction of this compound with carbon dioxide, (3) reaction of an a -bromo-styrene with lithium butyl and carbon dioxide, (4) reaction of a phenyl-acetylene with nickel carbonyl in glacial acetic acid, (5) reacting a phenyl-malonic ester with methoxymethyl chloride and treating the a -phenyl-a -methoxy-methyl-malonic ester formed with 50% KOH, or (6) reacting a phenylmalonic acid with dimethylamine and formaldehyde, refluxing the a -dimethylaminomethyl-a -phenyl-malonic acid formed and treating it with hydrochloric acid. The salts may be prepared by neutralizing the acid with an organic or inorganic base.  The amides may be prepared by reacting the appropriate acid halide with ammonia.  The esters may be prepared by esterification of the free acid, conversion of the free acid to the acid chloride which is then reacted with an alcohol, or by reacting an a -keto-phenylacetic acid ester with a Grignard reagent and dehydrating the resulting a -hydroxy-a -phenylpropionic acid ester by fusion and distillation.  Therapeutic compositions, which are useful for the relief of pain, fever and inflammation, and which may be administered orally as capsules, tablets, lozenges, effervescent granules, mixtures, elixirs, syrups or suspensions, topically as ointments, creams or lotions, or parenterally, contain as active ingredient compounds of Formula I above.  a -Dimethylqminomethyl-a -4-cyclohexylphenyl-malonic acid is prepared by treating ethyl 4-cyclohexylphenylmalonate with sodium hydroxide, collecting the sodium salt which is then dissolved in water and the solution acidified to give 4-cyclohexylphenylmalonic acid which is reacted with an aqueous solution of dimethylamine and formaldehyde solution.

[Also in Groups XXVI and XXXIII] The invention of the parent Specification is modified in that the laminations of longitudinally-extending resin-impregnated fibres are stressed in tension during manufacture of the blade so that in the completed blade the resin is subjected to compressive stress. The axialflow compressor blade shown is formed of laminations 14 of longitudinally-extending,  resin-impregnated glass fibres which are held in the moulding machine 24 by means of clamps 18, 19 and are stressed in tension by means of springs 16, 17. The lef-hand ends of the laminations are spread apart by means of a floating die member 29 and are clamped thereto by means of the U-shaped clamping pieces 21a. A cross-piece 15 of resin-impregnated glass fabric laminations is inserted between the spaced-apart portions. The upper die is moved downwardly and the profile portion of the blade is formed between the surfaces 25, 26 of the moulding dies 22, 23 and the root portion is formed between the surfaces 27, 28 of the dies 22, 23 and the surfaces of the floating die member. The blade is removed from the moulding machine and then trimmed. In a further embodiment, facing layers of resinimpregnated glass fabric are placed on the upper and lower surfaces of the pre-stressed laminations but are not pre-stressed in tension, the facing layers in the moulded blade being stressed in compression. The invention is applicable also to airscrew blades and to blades for rotary-wing aircraft.
