Title: New hydrazine carboxylic acid halides and process for preparing same
IPC: C07D307/74
Filed: 1960-04-28
Abstract: The invention comprises hydrazine-N1-mono-carboxylic acid halides in which the N2-nitrogen atom carries a substituted methylidene or an acyl radical capable of being split off by hydrolysis, and salts thereof; and their preparation by reacting the corresponding hydrazine with a carbonic acid dihalide, such as phosgene.  Preferred compounds are those of the formula R=N-NR1-COCl, where R is a benzylidene or furfurylidene radical which may be substituted, and R1 is an alkyl or cycloalkyl radical of up to 7 carbon atoms or a benzyl, phenyl or pyridyl radical which may be substituted; it is stated that such compounds are of use as disinfectants.  In general, the N1-nitrogen substituent may be aliphatic, cycloaliphatic, araliphatic, aromatic, heterocyclic-aliphatic or heterocyclic, and substituents may be present, such as free or substituted hydroxyl or mercapto groups, tertiary amino, chlorine, bromine, iodine, trifluoroalkyl and nitro.  The substituted methylidene radical may be an alkylidene, benzylidene or heterocyclic methylidene radical, with or without substituents as above; and specified acyl radicals are those derived from acetic, trifluoroacetic, propionic and butyric acids.  Many salt forming acids are listed.  The compounds of the invention react with ammonia, amines and alcoholates to produce semicarbazides and hydrazine carboxylic esters, and the hydrolysable N2-substituent may then be split off; thus N2-benzal-N1-methyl-hydrazine-N1-mono-carboxylic acid chloride is reacted with ammonia and the product hy drolysed to 2-methyl-semicarbazide.  Similarly, the hydrochloride of N2-benzal-N1-methylhydrazine - N1 - carboxylic acid N1 - methylpiperazide is obtained from N2-benzal-N1-methylhydrazine - N1 - monocarboxylic acid chloride and N-methylpiperazine.  N2 - (5 - Nitrofurfurylidene) - N1 - (p - methoxy - benzyl) - hydrazine and N2 - (p - nitrobenzal) - N1-cyclohexylhydrazine are prepared by reaction between 5-nitrofuran-2-aldehyde and p-methoxybenzylhydrazine, and p-nitrobenzaldehyde and cyclohexylhydrazine, respectively.

Title: Improvements in friction facing and process of making same
IPC: B32B27/00
Filed: 1921-06-01
Abstract: 188,012. Kirschbraun, L. June 1, 1921. Clutches, friction.-A friction facing is formed by saturating sheeted unwoven asbestos fibres with a solution of asphalt and phenol, subjecting the saturated sheet to the action of formaldehyde and baking to harden. Articles, for example clutch rings, are cut from asbestos millboard, and calendered and dried as usual, and immersed in a solution of asphalt or asphaltic oil and phenol to which may be added a thinning agent. A suitable mixture is 80 per cent Mexican bitumen melting at less than 100‹ F., and 20 per cent phenol. If volatile solvent is present, it may be removed at this stage by a slight baking. The article is now immersed in formaldehyde or subjected to formaldehyde vapours. The article is then baked at a sufficiently high temperature until the asphalt becomes unaffected and the article attains a Brinnell hardness exceeding 15, and tensile strength exceeding 2000 lbs. per square inch. According to a modification, instead of treating with formaldehyde, an oxidizing agent may be added to the material which will react with the asphalt on baking and produce aldehyde like bodies.

Title: Photographic printing apparatus
IPC: G01J1/42
Filed: 1959-05-04
Abstract: 915,310. Photographic apparatus. AGFA A.G. May 4, 1959 [May 7, 1958], No. 15265/59. Classes 98 (1) and 98 (2). A photographic printing apparatus for enlargements (Fig. 2), or for contact printing includes, separate and screened from the printing light source 2, a second source 36 from which light is reflected by the diffusing mirror 35 to illuminate a set of sample negatives at 34 of varying contrast with which may be compared, on a juxtaposed translucent screen 33, the contrast of the negative or transparency 8 to be printed. This latter is illuminated by the printing light source 2 via the condenser 3 and imaged by the lens 9 either on the sensitive surface 21 or, by interposition of the mirror 31, on the screen 33 for prior inspection of contrast, and standardization against one of the sample negatives at 34. Before this is done, the illuminations of the screens 33 and 34 are first of all matched by means of a diaphragm 12 operated by the handle 14. Depression of one of a set of keys 29 corresponding to the selected sample negative and visible juxtaposedly to it by means of the mirror 40, causes the mirror 31 to swing down to the position 31a thereby allowing light from the negative or transparency 8 to reach the printing surface 21, and also regulating in a predetermined manner a variable diaphragm 26 which controls the amount of background light from lamp 25 to produce varying degrees of softening in the contrast paper 21. The mirror 27 for reflecting the background light on to 21 has a central aperture 28 to allow passage of the imaging beam which latter is monitored for exposure time by means of the photo-cell 23. If no background light is used, printing papers of varying chosen contrast may be conveniently stored for easy selection in compartments adjacent the appropriate sample negative, the whole forming an independent unit which can be placed next to an enlargement image for comparison, as shown in Fig. 3.

Title: Improvements in or relating to novel catalyst system and olefin polymerization therewith
IPC: C08F10/00
Filed: 1962-04-19
Abstract: 966,788. Polymerization catalysts for 1-alkenes. AVISUN CORPORATION. April 19, 1962 [April 19, 1961; July 14, 1961), No. 15370/62. Heading C3P. A polymerization catalytic composition consists essentially of an alkyl aluminium compound selected from alkyl aluminium dihalides and alkyl aluminium sesquihalides, TiCl 3 , and a silicon compound selected from alkoxy silanes of the formula R 1 R 2 R 3 R 4 Si where R 1  is an alkoxy radical, R 2 , R 3 , and R 4 , are selected from alkoxy and hydrocarbon radicals, and alkyl disiloxanes. In the composition the mol ratio of the alkyl aluminium compound to TiCl 3  is from 0À2:1 to 10:1, and the atomic ratio of Al to active silane oxygen is from 5:4 to 10:1. The TiCl 3  component of the catalyst is essentially amorphous, i.e. it has been ball-milled until its crystallinity is below about 10 % of the original TiCl 3 , as determined by X-ray analysis. The catalytic composition is used for polymerizing 1-alkenes in the presence of an inert solvent or diluent. The Al compound may be ethyl, propyl or butyl aluminium dichloride, dibromide, or di-iodide. The silicon component may be trimethylethoxysilane, diethyldiethoxysilane, tetramethoxysilane, tetraethoxysilane, triphenylethoxysilane, hexaethyldisiloxane, or hexamethyldisiloxane. In the examples the polymerization of propylene, and 4-methylpentene-1, is described. The polymers are recovered by conventional techniques, e.g. addition of methanol, and subsequently fractionated by solvent extraction techniques such as treatment with heptane and pentane. The catalyst may be "aged" before use. U.S.A. Specification 2,967,206 is referred to.

Title: Programmer apparatus
IPC: D06F34/30
Filed: 1972-04-04
Abstract: 1341660 Valves ETABS CARPANO & PONSSA 4 April 1972 [7 April 1971] 15476/72 Heading F2V [Also in Division H1] To avoid the difficulty of manually setting an accurate start position of a programming cam assembly 1 (for electric, hydraulic, or pneumatic switching) due to the uneven loading as the assembly is rotated, means are provided whereby the manual adjustment does not directly rotate the assembly 1 but sets two mutually coupled special coaxial cams 5 and 10 having slight lost motion therebetween which causes a common follower 16 to energize means for rapid automatic rotation of assembly 1 to the set start position, whereupon the said lost motion is taken up and automatic rotation ceases. Cams 5 and 10 have identical profiles of regular peaks and troughs, and a clutch member 2 ensures that these cams are coupled to the assembly 1 under automatic drive conditions but are disconnected during manual control. As shown, cam assembly 1 is loose on a shaft 6 but coupled by splines (Fig. 3, not shown) to member 2, which is axially loaded by spring 7 and has at least one sawtooth lug 4 engaging cam 5 such that rotation of cam assembly 1 turns cam 5, but turning cam 5 moves member 2 axially and does not rotate assembly 1. Cam 5 has a lug 8 engaging an aperture 15 in cam 10 with lost motion equal to the pitch of the profiles of cams 5 and 10, which corresponds to one normal  step of assembly 1. Shaft 1 is pinned to cam 10 at 22 and to a knob 20 at 21. When knob 20 is turned to set a desired start position the cam 10 (but not assembly 1) is rotated, aperture 15 entrains lug 8, and cams 5 and 10 are thus moved to the selected start position with their profiles in alignment. Common follower 16 thus closes contacts 18, 19 to energize drive means (not shown) which rotates assembly 1 and member 2 rapidly until lug 4 enters a recess in cam 5, entraining the latter to take up the lost motion and restore cams 5 and 10 out of alignment. Follower 16 is thus urged to open contacts 18, 19 and stop the rapid advance with assembly 1 in the desired start position.
