Title: Production of bicyclo-[2,2,1]-heptadiene-(2,5)
Inventor: REICHENEDER FRANZ
IPC: C07C2/50
Filed: 1960-08-12
Abstract: Bicyclo-[2.2.1]-heptadiene-2,5 is obtained by reacting dicyclopentadiene with a mixture of acetylene and an inert gas containing 10%-25% of acetylene at 150 DEG C.-250 DEG C. and a total pressure of 75-400 atmospheres which is (a) below the decomposition limiting pressure of the gas mixture and (b) such that the acetylene concentration in the liquid phase is below the ignition limiting concentration of 130 ccs. (measured at N.T.P.) per cc. of liquid. The acetylene may be mixed with nitrogen, helium, neon, argon or methane, and the acetylene partial pressure is preferably such that the concentration of acetylene in the liquid is 90-120 ccs. per cc. assuming a solubility of 3 ccs. per cc. per atmosphere at working temperature.  Solvents may be present such as hydrocarbons, e.g. benzene, toluene, xylene, ethylbenzene, isopropylbenzene, diisopropylbenzene, tetrahydronaphthalene, decahydronaphthalene, cyclopentane, cyclohexane, methylcyclohexane, cyclooctane or C6-C16 aliphatic hydrocarbons; ketones, e.g. acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone or cyclooctanone; esters, e.g. ethyl acetate, butyl acetate, methyl butyrate, methyl benzoate, propyl benzoate, dimethyl phthalate, dioctyl phthalate, or dimethyl adipate; ethers, e.g. dioxane, tetrahydrofuran, anisole or diisopropyl ether; amides, e.g. formamide, dimethyl formamide, acetamide, dimethylacetamide, butyramide, N-methyl butyramide, N,N-dibutyl butyramide, hexanoic acid amide, N-methyl hexanoic acid amide, N-methylpyrrolidone-2 or N-methylpiperidone-2; and lactones, e.g. butyrolactone, valerolactone or ethylbutyrolactone.  The concentration of dicyclopentadiene in the solvent may be 20%-80% by volume and a polymerisation inhibitor may be added, e.g. hydroquinone, pyrogallol, butypyrocatechol, C1-C8 alkyl esters of gallic acid, phenothiazine or methylene blue.  The process may be effected batchwise or continuously, in the latter case using the sump or trickle technique, and the solution may be presaturated with acetylene.

Abstract: 887,965. Sheet piling. AANNEMING MIJ J. P. VAN EESTEREN N.V. Aug. 15, 1960 [March 16, 1960], No. 28115/60. Class 68(2). To prevent sheet piling from bending forward when the ground in front is excavated, each pile 2 is rammed in with a cable 3 previously attached to or near its lower end and, at the same time or subsequently, to the upper end thereof, and of a greater length than the distance between its points of fixation to the pile, and after ramming and, if desired, after the excavation of material from in front of the pile, the cable between its points of attachment to the pile is tightened in a plane perpendicular to the plane of the pile and secured in its tightened condition. The cable is connected to an eye-piece 4 detachably held in a sleeve 7 welded around a hole in the pile. The cable may be tightened by coupling a tensioning member 9 to the eye-piece and progressively inserting said member from the front of the pile through said sleeve. The tensioning member is held in position by a pin 8 inserted in an opening 10 in the member and an opening in the sleeve.

Title: Improvements in or relating to tag attaching staple machine
IPC: B65C5/00
Filed: 1957-09-06
Abstract: 865,145. Stapling machines; applying tags. SWINGLINE Inc. Sept. 6, 1957 [July 9, 1957], No. 28235/57. Class 89(3) [Also in Group XXII]. An electric stapling machine for applying a tag to a garment comprises a staple containing arm SA, Fig. 1, motion transmitter MT, Fig. 4, and operating solenoid SD, of the kind described in Specification 823,561, the arm SA being swingable relative to a casing C which is mounted upon a base CB to which is pivoted a carrier SC provided with an anvil A and clamping means CM, Fig. 8, for removably clasping the front part of a tag T over the anvil, a rail G, being secured to the casing C and disposed in advance of the magazine M for folding the rear part of the tag T over the front part GF as the SC is swung towards the magazine. A holder H carrying a normally open switch MS in the solenoid circuit is secured to the carrier and the holder H is provided with formations 77 which locate a garment GF with respect to the anvil A. A switch actuator in the form of a tiltable spring loaded and flexible lever 80 is provided on the carrier SC, the upper end of the lever 80 having a strap ST for engagement by the fingers of the operator. With a tag T secured by its front part in the clamp CM and its rear part resting on the rail G, Fig. 2, and with a garment GF placed over the front part of the tag T against the formations 77, the operator applies pressure to the strap ST which first causes the carrier to swing towards the arm SA whereby the rear part of the tag T is folded over the garment GF. Swinging movement of the carrier SC is limited by a stop 95 carried by a yoke Y when the anvil A is correctly aligned with the magazine M. Continued pressure by the operator upon the strap ST causes the arm 80 to swing and flex towards the carrier SC until it engages a knob K to close the contacts of the micro-switch MS. The solenoid SD is thereby actuated and a staple is driven through the tag T folded over the garment GF. The tag T, secured to the garment GF is then removed from the clamp CM by pulling through the relief gap 102 between the carrier SC and the arm SA. The anvil A is formed by bending the upper end of the carrier SC into the form shown in Fig. 28 and stamping in the clenching faces 65 Figs. 29 and 30 and undulations 133, 134 to lock the parts against relative displacement.

Abstract: 460,058. Vehicle brakes. CROSSLEY MOTORS, Ltd., and RANDLE, F. E. Oct. 16, 1935, No. 28568. [Class 103 (i)] Brake mechanism for motor vehicles comprises two sets of brakes adapted to be simultaneously applied by two operating members and pairs of interengaging abutments associated with the operating mechanism of each set, one abutment of each pair being removable to permit independent operation of the sets when desired. An arrangement for the rear wheels of a six-wheeled vehicle is shown and comprises two crank levers a, b connected respectively by rods d, i to the brakes on the wheels e, j. Lever a is connected also by rod c cross-shaft q and contact arms t to the hand-lever and lever b by connections f, g, h. cross-shaft p and contact arms s to the pedal, Each lever a carries a roller u for engagement with a bolt v on the other lever, one only of the bolts being visible in the drawings. Both sets of brakes are thus normally operated by the pedal and hand lever but if it is desired to operate the brakes on one pair of wheels independently of those on the other pair the bolts v are adjusted so as not to engage the rollers. The provision of the contact arms s, t ensures that when the two sets of brakes are interconnected, the pedal does not actuate the hand lever and vice versa. A servomotor is shown at r.

Title: Manufacture of anthraquinone nitriles
IPC: C09B1/00
Filed: 1926-11-15
Abstract: 261,422. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). Nov. 13, 1925, [Convention date]. Anthraquinone nitriles are produced by treating halogen anthraquinones at a high temperature with cuprous cyanide in presence of an aliphatic or aromatic-aliphatic nitrile. When the latter is of low boiling point, as in the case of acetonitrile, the reaction may be effected in a closed vessel, but when the nitrile is of high boiling point, as in the case of benzyl cyanide, the reaction is complete at the said boiling point. The initial products of reaction are complex compounds containing the anthraquinone nitrile, copper, and the aliphatic &c. nitrile; by treatment with nitric acid and steam distillation the copper dissolves and the aliphatic &c. nitrile passes over, leaving the anthraquinone nitrile. When the halogen anthraquinone contains several halogen atoms the latter may be substituted in succession by CN groups. According to examples the following nitriles are prepared :-Anthraquinone-1-nitrile, anthraquinone-1:2-, 1:3-, 1:4-, and 1:5-dinitriles, 1:4:5-tricyano-8-chloranthraquinone, 1:4:5:8- and 1:2:3:4-anthraquinone-tetranitrile, from the corresponding chloranthraquinones; a nitrile from 1: 3-dibrom-2-aminoanthraquinone. The nitriles yield green vats with hydrosulphite and the corresponding carboxylic acids by saponification; thus the 1-nitrile and 1 : 5-dinitrile by treatment with sulphuric acid and sodium nitrite yields the corresponding carboxylic acids. The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of 1-amino-2-brom-4-anthraquinone-nitrile. This subject-matter does not appear in the Specification as accepted.
