Title: New betaines and process for their manufacture
Inventor: REUTER MARTIN
IPC: C07D233/14
Filed: 1963-06-24
Abstract: The invention comprises cyclo-amidines of the general Formula I <FORM:1043502/C2/1> wherein R and R1 each represent an alkyl radical, which may be interrupted by a heteroatom or heteroatom group, or a cycloalkyl or aryl radical, which alkyl, cycloalkyl or aryl radicals may be substituted by halogen-free substituents; R2 represents an ethylene or propylene radical which may be substituted or an unsubstituted phenylene radical; R3 represents an alkyl radical containing up to three carbon atoms; and Z represents an acid group containing oxygen.  These cyclo-amidines may be prepared by treating a cycloamidine of the general Formula II <FORM:1043502/C2/2> in the absence of an alkali with a salt of a monohalogen organic acid of the general formula Hal.-R3-Z-M wherein Hal. represents a halogen atom and M represents an ammonium radical, an alkali metal or alkaline earth metal.  The reaction may be effected in the presence of a solvent, e.g. water, benzene, acetonitrile and chloroform, but is preferably effected in a melt of the cyclo-amidine reactant at 50 DEG to 150 DEG  C.  If the cyclo-amidine product is to contain an alcoholic hydroxy group it is also possible to prepare said product by reacting the metallic alcoholate of the corresponding cyclo-amidine of Formula II with a free halogen organic acid of the formula Hal.-R3-Z-H.  Specified Z groups are CO2 and SO3, specified hetero atoms and heteroatom groups interrupting R and R1 alkyl radicals are O, N, S and NHCO, and specified substituents in R and R1 are -OH, -OCH3 and -CONH2 groups.

Title: Improvements in and relating to driving mechanisms
IPC: A01K89/015
Filed: 1929-08-17
Abstract: 328,178. Whipp, F. Aug. 17,1929. Clutches.-A reel 7 for a fishing line or the like is rotated by means of a handle 15 a pin of which 13 presses a roller 12 between the surfaces of an extension of the reel 8 and an eccentric portion 11 of a sleeve 10. The sleeve rotates with the reel in a winding direction. A spring 22 grips at one end a pin 20 which is fixed to a radial extension 16 of the sleeve 10. 'The other end of the spring 23 acts as a stop for the roller 12. A pin 19 slides transversely in a hole in the spindle and during the winding of the line rides over three ratchet teeth formed on the inside of the sleeve 10. A sudden pull on the fishing line reverses the rotation of the reel, the ratchet grips the sleeve 10 through the pin 19, and the roller is freed from the constricted area between the reel 8 and the sleeve 11. The winding force on the handle 15 must be greater than the resistance before the line can be rewound. Gearing may be interposed between the handle and the reel. The device may be applied to the starting handles of motor cars. The device may be loaded horizontally by means of a screw thread on the spindle or a coil spring interposed between the handle and the extension on the spool.
Patent GB-169451-A (GB)
Title: Improved manufacture of a composite material formed with condensation products
IPC: C08G8/00
Filed: 1921-09-22
Abstract: Compositions comprising a fibrous base containing a carbohydrate such as cellulose, impregnated with a condensation-product such as phenol-formaldehyde, are made by parchmentizing the fibres and treating the product with the reacting substances successively or simultaneously so that the condensation takes place within the fibres.  The usual parchmentizing-agents may be employed, but caustic soda, sodium or ammonium zincate, stannates, stannites, antimonates, aluminates, titanates or similar substances are preferred as they act as p  catalysts for the subsequent condensation.  In one example of the process, a roll of paper is led through a 20 per cent solution of caustic soda containing 10-15 per cent of sodium chloride, then through a bath of phenol, and then through a chamber containing formaldehyde vapour.  The paper is next pressed between hot rollers to cause partial condensation, after which the parchmentizing-agent may be washed out before the reaction is completed by further heat and pressure.  The phenol may be replaced by cresol and other homologues, and the formaldehyde by trioxymethylene, hexamethylenetetramine, or other substances having an active methylene group.  The subject-matter of Specifications 28009/07, 1922/08, 28155/10, 2098/13, and 121,301 is disclaimed.  The Specification as open to inspection under Sect. 91 (3) (a) states that other carbohydrates, such as sugar and starch, may be substituted for cellulose, and that the parchmentizing process may be omitted.  This subject-matter does not appear in the Specification as accepted.

Abstract: 265,651. Courmont, H. Oct. 9, 1925. Transfers.-A chromo-lithographic transfer for decorating wood, metal, stone, glass, or other materials is prepared by printing the design upon a sheet of gummed paper, coating the design with a material adapted to form a strong supple and insoluble supporting film for the design when transferred, and finally applying a further coating of a casein-containing substance by which the transfer is secured to the article to be decorated. The material to form the supporting film preferably consists of a mixture of 900 parts by weight of copal varnish, 75 parts of linseed oil, and 25 parts of indiarubber, and the ink for printing the design is preferably prepared by adding to ordinary lithographic, ink about 15 per cent by weight of the same mixture. The supporting film may, however, consist of copal varnish alone, or other suitable substances such as celluloid varnish, collodion, or gelatine rendered insoluble by formol. After the film is dry it is coated with a mixture of 500 parts of casein, 400 parts of water, 10 parts of soap, 20 parts of formol, and 70 parts of sodium carbonate. To use the transfers they are moistened and applied to the surface to be decorated, after which the paper backing is stripped off.

[Also in Division F2] A mechanism to produce variable stepwise rotary movement of the drive wheel 15 of a paper feed comprises a drive shaft 10 which through gears 11, 24 rotates a lever 25 having a pivoted drive lever 26 with a cam follower 46 which can be selectively engaged with one of the cam tracks 43-45 by a lever 48. A spring 21 urges the wheel 15 and driven shaft 13 to a home position. The drive lever 26 engages a ratchet wheel 29 secured to the shaft 13 which a series of teeth one, 31, of which is of extended length and also a part devoid of teeth, at a point determined by the cam track selected. With the cam surface 45 engaged no rotation of the ratchet wheel is effected while the channel 44 produces a single tooth advance and the channel 43 a three tooth advance after the lever 26 having first engaged the long tooth 31 to move it to the surface 66 at the end of the channel 43 from whatever position it was in originally. This last action allows the taking of a sub total on the paper sheet 17 and thereafter a further cycle through the channel 43 will cause a further three tooth advance for a total. On completion of the advance of the sheet 17 a stud 62, Fig. 5, on the ratchet wheel engages a reset lever 52 to bring a surface 60 to be engaged at 64 by a pin 27 on its return to its home position to release a detent of a lever 51 to allow the spring 21 to restore the shaft 13 to its home position.

Further, the pile in selected transverse rows is either of different heights or comprises both pile loops 27 or pile tufts 28. In forming the fabric, tufts or high loops are made in any row by raising the desired pile warp yarns 26a over a pile wire 48 in the usual way, and the pile warps are maintained under slack tension. The shedding operation is modified so that when a weft yarn 22, inserted into the shed immediately following that into which a pile wire 48 was inserted, is beaten up, the weft yarn engages all the pile warp yarns and pushes them ahead of it to form relatively low loops. When the weft yarn is fully beaten up, the reed 47 engages the previously inserted wire 48 and causes. it to stand erect to form loops of the height of the wire. U.S.A.
