IPC: A47K13/10
Filed: 1926-03-20
Abstract: 249,557. Preu, M. March 20, 1925, [Convention date]. Checks.-In mechanism for operating theatre and other seats, and for operating also the flushing mechanism in the case of closet seats, of the type comprising a foot lever and an oil &c. brake, a spring-actuated sleeve 4, Fig. 3, engages by means of a pin a slot in a hinge plate 26, and the brake 13 is interposed between another hinge plate 16 and a. fixed portion of the device. The spring connected to the sleeve 4 surrounds a fixed spindle 1 and is connected to a sleeve 9, which may be rotated to impart an initial tension to the spring and then secured in position, said initial tension holding the seat raised. By means of a pedal E, Fig. 1, connected to a lever 37 on the sleeve 4, the pin is moved in the slot in the plate 26, and the seat falls by gravity to a position where a pawl engages a ratchet tooth on the sleeve. When weight is applied to the seat, it is depressed further, the pawl being disengaged and additional tension being imparted to the spring; subsequent removal of the weight allows the spring to return the seat to its raised position. In the case of a closet seat the rising actuates flushing means C through a lever 29. The brake 13 contains liquid in a casing carried by the hinge plate 16, and a vane 17, Fig. 5, carried by the fixed spindle 1 has a small aperture 19. In an alternative form, the brake casing carries a member having a liquid passage 19, Fig. 22, provided with a regulating member 15<b>. The Specification as open to inspection under Sect. 91 (3) (a) states also that the invention is applicable to doors, and in a door-operating device, the brake has a large passage 53, Fig. 25 (Cancelled) fitted with a non-return valve 18, and a small passage 19. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the manufacture of screw caps for containers
IPC: B21D51/50
Filed: 1953-03-24
Abstract: 776,645. Making screw caps. ROBINSON, F. G. Feb. 24, 1954 [March 24, 1953; April 13, 1953], Nos. 8010/53 and 9958/53. Class 83 (2). In a method of manufacturing screw caps of the kind comprising inner and outer members, the outer member 2 is formed with a laterally extending flange 3 having an edge 4 of irregular form, the flange being drawn off to its full depth after which the inner member 6 is inserted and the outer member curled over the inner member. The edge 4 is given a " wavy " trim, the convex positions 5, in the case of a hexagonal screw cap, occurring at the corners and mid-way between each corner of the cap. The " wavy " trim ensures that during the curling, the high or convex portions of the flange are partially curled first and this prevents any collapse of the outer member. Alternatively, the " wavy " edge may be formed after the outer member has been fully drawn by placing the drawn member on a block and subjecting it to the sideways action of cutting jaws. Specification 676,984, [Group XVII], is referred to.

Title: Improvements in or relating to a method for producing 5:6-dimethoxy-8-aminoquinoline
IPC: C07D215/40
Filed: 1947-03-26
Abstract: 5 : 6 - Dimethoxy - 8 - aminoquinoline is prepared by adding concentrated sulphuric acid to a mixture of 4-acetamino-5-nitroveratrole, glycerin and arsenic acid at about 150 DEG  C., permitting the exothermic reaction to continue for a period between 90 seconds and 15 minutes, rapidly cooling the mixture to terminate the reaction, and reducing the resulting 5 : 6 - dimethoxy - 8 - nitroquinoline with hydrogen.  The reaction may be effected by heating a mixture of concentrated sulphuric acid, 4 - acetamino - 5 - nitroveratrole, glycerin and arsenic acid to a temperature of about 150 DEG  C. to initiate the exothermic reaction which is allowed to continue for about 90 seconds, and the resulting 5 : 6-dimethoxy-8-nitroquinoline is reduced with stannous chloride.  The initial reaction may be terminated by pouring the reaction mixture into water.  Specification 351,068 is referred to.
Patent GB-806769-A (GB)
Title: Improvements in or relating to the production of esters
Inventor: CHIRAS STANLEY JOSEPH
IPC: C07F5/04
Filed: 1957-03-13
Abstract: Esters having a boiling-point below 100 DEG  C. are prepared by continuously reacting an acid and an alcohol in a reaction zone in which esterification conditions of temperature and acid concentration are maintained, continuously recovering the ester by distillation, continuously removing reaction liquor from the reaction zone and contacting it with a cationic exchange resin to remove water, and recycling incompletely reacted material to the reaction zone.  The resin is preferably arranged in parallel flow beds, one being used for the dehydration while another is being regenerated.  Preferred resins are those of the sulphonic acid type, such as Zeo-Karb H, Amberlite IR-120, Permutit 216, Dowex 50, Ionac C-200, Duolite C-3, Wofatit P, Wofatit C and Alkalex ("ZeoKarb," "Amberlite" and "Permutit" are Registered Trade Marks).  The resin is preferably presaturated with the alcohol or the equilibrium reaction mixture. It may be regenerated by washing or distilling out adsorbed water, e.g. with a solvent naphtha or by azeotropic distillation with Skellysolve-C (technical n-heptane).  The treated reaction liquor may be returned as such to the reaction zone or the ester first recovered by distillation.  The ester may be continuously distilled directly from the reaction zone, or from continuously withdrawn reaction liquor; or the reaction liquor can be continuously withdrawn in a single or combined stream to be passed successively through dehydration and distillation zones in any sequence.  Examples describe the preparation of trimethyl borate; with this ester residence times in the reaction zone of less than 15 minutes and an instantaneous ester concentration representing a conversion of 2-30 per cent of acid are preferred.  Other esters mentioned are methyl, ethyl and isopropyl formates, methyl, ethyl and vinyl acetates, methyl chloroformate, methyl propionate, methyl isobutyrate and lower alkyl esters of inorganic acids, such as propyl nitrite, ethyl nitrate and methyl carbonate.

Abstract: Melamine is prepared by heating urea, preferably in the absence of added ammonia or ammonium salts, under elevated pressure in the presence of a finely divided or finely dispersed catalyst consisting of one or more non-precious non-alkali metals or oxides, salts or compounds of such metals.  The reaction is preferably conducted under a pressure of 70-100 atmospheres and at a temperature of 400-450 DEG C. using an amount of catalyst between 0.1 and 5 per cent by weight of the urea to be reacted. The catalyst is preferably a finely divided nonprecious heavy metal capable of forming oxides having acid properties.  Specified catalysts are finely divided iron, cobalt, nickel, manganese, chromium, tin, zinc, copper, aluminium, magnesium and calcium; salts of iron, tin (e.g. stannic chloride), copper (e.g. copper sulphate) and chromium (e.g. chromic nitrate); finely divided oxides of aluminium, magnesium and calcium; or mixtures thereof. In a preferred process a mixture of molten urea and catalyst is passed continuously, under a pressure of at least 60 atmospheres, through a reaction zone heated to at least 290 DEG  C., and is continuously subjected to such conditions for a time sufficient to convert substantially all the urea into melamine; the gaseous reaction products are continuously collected separately from the liquid reaction mixture (e.g. with the aid of enlargements in the reaction tube) and are then intermittently removed from the reaction zone (e.g. by releasing the pressure).
