Title: Process and catalyst for ring opening polymerisation
IPC: C08G61/08
Filed: 1973-04-05
Abstract: 1376577 Ring-opening polymerization catalyst BAYER AG 5 April 1973 [8 April 1972] 16282/73 Heading C3P A catalyst for ring-opening polymerization of cyclo-olefins or their halogen-substituted analogues comprises the reaction product of (a) a molybdenum compound; (b) an ether; (c) an organo-aluminium compound and (d) a Lewis acid. The Lewis acid is preferably a halide of an element of Group IVA, VA, IIIB, or IVB and may be used in the form of an adduct of the ether. Preferably components (a) (b) and (d) are reacted together first and component (c) is then added before or after the monomer. The catalyst may also contain iodine and/or a chlorinated aromatic hydrocarbon. It is suitale for use in an inert organic solvent such as toluene, chlorobenzene or cyclohexane. In examples cyclooctadiene-1,5-cyclo-octene and cyclopentene, in some cases mixed with a small amount of 1- butene, are polymerized. The exemplified catalysts are derived from MoCl 5 , BF 3 .OEt 2  and Et 2 AlCl, Et 2 Al(OEt),Et 3 Al or Et 3 Al 2 Cl 3 , and optionally iodine, in chlorinated biphenyl.

Title: Synthetic resin composition
IPC: C08G14/08
Filed: 1937-06-12
Abstract: Resinous compositions are prepared by condensing simultaneously, in weakly acid solution. a phenolic body and urea or thiourea with formaldehyde and mixing the soluble resin thus obtained with a polyhydric alcohol-phthalic acid condensation product.  The molecular ratio of the formaldehyde to the phenol and urea is about half.  In an example, cresylic acid and urea are condensed with formaldehyde in the presence of zinc acetate and the dehydrated condensation product is blended with a condensation product prepared by condensing phthalic anhydride with glycerol.  The mixture is dissolved in a suitable solvent. The product may be used to render textile materials resistant to attack of corrosive materials.

Abstract: 592,975. Manually - actuated valves. TRIGGS, W. W. (Willys-Overland Motors, Inc.). Aug. 31, 1944, No. 16597. [Class 135] [Also in Groups XXII and XXIII] A riveting machine or other fluid-actuated mechanism is controlled by a valve 22 connected to means biassed to effect or permit its closure and means to retard the rate of closure. The valve comprises a spring-pressed member 22 which is arranged in a sleeve 19 in the handle 11 of the machine and is moved down, to supply air to the hammer arranged in the body 10, by a wedge 35, link 57 and trigger 78. This is connected by a rod 70 to the piston 67 of a dashpot 63 having a spring 73 to move it to the left and close the valve 22 at a rate regulated by controlling the escape of air from the lefthand end 62 of the cylinder 63 by a screw valve 65. A non-return spring-controlled valve 74, Fig. 3, in the piston 67 admits air rapidly to the end 62 when the valve 22 is opened. When the piston 67 is near the end 62, the air on the two sides of it is connected by a passage 77. The air supply pipe 45 is connected to the valve 22 through a regulating valve 46.
Patent GB-824425-A (GB)
Title: 4-piperidyl esters
Filed: 1957-05-24
Abstract: The invention comprises compounds of the general formula <FORM:0824425/IV (b)/1> and acid addition salts thereof, wherein R1 represents an alkoxy (1-4 carbon atoms), an alkyl (1-4 carbon atoms), an NH-alkyl (1-4 carbon atoms), or an alkoxy-alkyl-NH group (2-8 carbon atoms), a chlorine or a bromine atom, and R2 represents an alkyl group (1-4 carbon atoms); and a process for the manufacture thereof by reacting a compound of the general formula <FORM:0824425/IV (b)/2> with a compound of the general formula <FORM:0824425/IV (b)/3> wherein R1 and R2 have the meaning above and X is a chlorine or bromine atom or an alkoxy group (1-3 carbon atoms). The reaction is preferably carried out at temperature of 150-200 DEG C., and in the presence of a condensing agent such as an alkali metal alcoholate or metallic sodium.  In the process wherein X in formula III is chlorine or bromine, the reaction is effected in such a way that the two starting materials are dissolved in an inert organic solvent such as benzene, toluene or xylene, and the resultant hydrogen halide salt of the ester is treated with an alkali to obtain the free ester.  In an example, p-n-butoxy-benzoyl chloride is reacted with 1-methyl-4-hydroxypiperidine in benzene, the free p-n-butoxybenzoic acid (1-methyl-4-piperidyl) ester being obtained by reaction with sodium carbonate.  Similarly are prepared the anisic acid, p-ethoxybenzoic acid, p-toluylic acid, p-chloro-benzoic acid, p-butyl-amino-benzoic acid (1-methyl-4-piperidyl) esters from 1-methyl-4-hydroxypiperidine and the appropriate acid chloride.  The p-n-butoxy-p-butyl-amino and p-methoxy-ethylamino - benzoic acid esters of 1 - methyl - 4 are also prepared by reacting the appropriate benzoic acid methyl or ethyl ester with the hydroxypiperidine in the presence of sodium ethylate.  The monohydrochloride acid addition salts are prepared from the basic esters by reaction with hydrochloric acid.

Title: A new or improved machine for marking nuts and like articles
IPC: B44B5/00
Filed: 1936-06-16
Abstract: 470,594. Marking nuts. RICHARDS & SONS, Ltd., C., and RICHARDS, P. R. June 16, 1936, No. 16712. [Class 83 (iv)] Nuts are marked on opposite faces by a pair of spring-loaded punches 17 striking simultaneously or successively, the withdrawal of the punch actuating a lever and reciprocating nut-holding slide 6, to drop the nut out of its holder 42 and allowing the bottom nut of a stack to drop into its place to be marked. The punch holders 7 and 16 are coupled together to move towards the nut by hand lever 12 or power, one being actuated by rack and pinion 9. When the dies touch the nut the die holder 7 continues forward, compressing a hammer spring 29 until a cam surface 33 slides a sleeve 37 up until its bore aligns with the hammer 27 which being released thereby, is forced by the spring 29 to strike the inner end of the die holder 17 to mark the nut. A spring 36 resets the sleeve 37 out of alignment for the next marking. The other punch may act similarly or may be merely a spring-pressed die which is forced back by the impact of the first die and then rebounds to mark the nut. The strength of the blow may be adjusted by adjusting the axial position of the end cap 30 against the abutting hammer spring 29. A spring 45 normally holds the work slide 6 in position, but if it is not in position a stop 51 on the lever 47 fouls a stop 52 on the punch holder and prevents actuation. The column of nuts is held in position by shaped side strips 39 adjusted to accommodate various sizes of nuts.

The superstructure comprises posts 29, 30, 31, 32 which take into hollow tubes 24 secured to the sides 11 of the trailer and are formed with wedge-shaped sockets 38 similar to that shown in Fig. 4, and receiving flanges 39 at the ends of transverse members 37 which support the tracks 40, 43, 44 for the upper three automobiles. When the superstructure is taken down deckboards 49, Fig. 4, may be placed in a channel 55 at the upper edges of the sides 11. The transversals 37 from the superstructure are then supported in sockets 38 on the tubes 24 to stay the sides 11 and to provide supports for longitudinal members supporting the boards 49. A similar function may be performed by the posts 29, 30, 31, 32 which are connected by removable pins to brackets below the channel 55. The back axle may be replaced by two half shafts so that the floor 10 extends to the rear of the trailer and the automobile A<2> is level instead of inclined, as shown.
