Abstract: 485,405. Riveting. HEINKEL, E. Feb. 3, 1937, No. 3252. Convention date, Feb. 3, 1936. [Class 83 (iv)] Joints.-A method of making countersunk riveted joints consists in holding thin metal sheets to be united between a guide for a rivet punch and a support, the shape of which conforms to the countersinking, striking the rivet through the imperforate sheets by the punch whereby the sheets are caused to assume the shape of the countersinking by the countersunk head of the rivet, and forming the closure head on the rivet. Sheets a, b are clamped between a guide a for a rivet punch f, and a support d, and the rivet e is projected with great velocity through the sheets by the punch f whereby the sheets are pierced and caused to assume the countersunk form of the tool d, as in Fig. 2. The rivet is headed by a tool i, Fig. 3, while the plates are held between members g, h. The parts d, h are preferably made in one piece, the bores being arranged side by side, or a bush formed similarly to the bore in the member d may be received in the bore in the part h. The tools c, f may replace the holder-up g, in which case the tool f may be rigidly connected to the casing c and driving-in tool during riveting. The holder-up g may be of lead, wood, or rubber, or may comprise a bag of leather or other material filled with sand, metallic particles, or the like. The rivet may be closed by explosion riveting as described in Specifications 467,514 and 467,515, the striking stamp being continuously heated, for instance electrically, and allowed to rest on the rivet, after it has been driven through the sheets, until the charge explodes. A separate exploding tool may, alternatively, be employed. According to the Specification as open to inspection under Sect. 91, the rivet may be headed by impact with a holder-up of lead when it is forced through the sheets to pierce them. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the preparation of phenthiazine derivatives
Filed: 1950-02-13
Abstract: The process of preparing the 10-dialkyl-aminoalkyl-phenthiazines of the parent Specification is carried out using as acid binding agent an alkali metal or its hydroxide, alkoxide, hydride or alkyl, aryl or aralkyl derivative. The process is particularly applicable to compounds where the 10-substituent is-(CR1R2)n -N(R3)2, R1 and R2 being hydrogen or methyl, R3 methyl or ethyl, n 2 or 3 and the grouping (CR1R2)n containing not more than 3 carbon atoms.  The dialkylaminoalkyl halide which is reacted with the phenthiazine is preferably used as a solution in an aromatic hydrocarbon (e.g. benzene, xylene or toluene) and the reaction is carried out at the boiling point of the solvent. When the group (CR1R2)n forms a branched chain isomerization takes place during the reaction giving a mixture of two products; these can be separated by conversion into hydrochlorides, fractional crystallization from alcohol and re-conversion to free bases.  In the examples, (1) N-dimethyl-aminoethylphenthiazine is made by heating phenthiazine with dimethylaminochloroethane, sodium and xylene; (2) as in (1) using caustic soda and toluene; (3) as in (2) using diethylaminochloroethane; (4) as in (2) using 1-dimethylamino - 2 - chloropropane in toluene; the resulting mixture of N-(21-dimethylaminopropyl) and N-(21-dimethylamino-isopropyl)-phenthiazines is separated by fractional crystallization of their hydrochlorides from ethanol; (5) as in (4) using 1-diethylamino-2-chloropropane; (6) N-dimethylaminoethylphenthiazine is made from phenthiazine, dimethylaminochloroethane and phenyl-lithium in xylene; (7) N-diethylaminoethylphenthiazine is prepared from phenthiazine, diethylaminochloroethane and sodium t-butoxide in xylene; (8) N-diethylaminoethylphenthiazine is made from phenthiazine, diethylaminochloroethane and lithium hydride in toluene.  The phenthiazine nucleus may contain alkyl or alkoxy substituents. Other specified acid binding agents are n-butyl-lithium, phenylsodium and triphenylmethyl-sodium.
