Title: Improvements in apparatus for applying adhesive to the closing flaps of paper and like bags, envelopes and the like
IPC: B31B150/00
Filed: 1937-12-03
Abstract: <PICT:0494631/III/1> <PICT:0494631/III/2> p  An apparatus for applying adhesive to the closing flaps of paper and like flat bags, envelopes and the like, which are conveyed past the apparatus in a circular path, comprises a reservoir 4 for the adhesive, and an inclined rotatable applying disc 2 which dips in the adhesive at its lower part while its upper part projects through a slot 5 in the wall of the reservoir.  Wipers or scrapers 6, 7 are arranged within the reservoir, above and below the disc 2, and the slot 5 is made deeper at the part through which the disc returns to the reservoir, to prevent any remaining adhesive from being wiped off on the outer wall of the reservoir.  A slotted scraper 8, through which the disc 2 passes, may be arranged on the front wall of the reservoir and overlapping the slot 5, and may be finely adjusted sideways, as by an eccentric 9, to regulate the amount of adhesive delivered by the disc.  The disc 2, the member which conveys the flat bags 12 in a circular path past the disc, and a grooved horizontally rotating abutment disc 13, are driven from a common driving shaft, to ensure a rolling contact between the disc and the closing flaps of the bags.

Title: Improvements in and relating to rustless iron alloys
IPC: C22C38/18
Filed: 1933-11-30
Abstract: A rustless iron alloy of inherently fine grain structure comprises 10 to 30 per cent of chromium, 0,06 to 0,09 per cent of carbon and 0,09 to 0,2 per cent of nitrogen, with or without up to 3 per cent of one or more of nickel, molybdenum, tungsten, vanadium, copper, the balance being substantially iron: small amounts of manganese and silicon may be present.  Rustless steel scrap, low-carbon scrap iron, and low-carbon ferrochrome may be melted in an induction furnace and brought to the desired temperature and condition of refinement, after which nitrogen is caused to flow through the melting chamber for a period of fifteen minutes to one hour or more: the composition is then finally adjusted, as by adding a small amount of low-carbon ferrochrome with or without additions of nickel, molybdenum, tungsten, vanadium, and copper.

Abstract: 809,031. Gas turbine plant. GENERAL ELECTRIC CO. Nov. 25, 1955 [Nov. 26, 1954], No. 33880/55. Class 110 (3). [Also in Group XII] An apparatus for the production of gaseous working fluid comprises a combustion chamber for the decomposition of injected fuel, a contiguous fuel storage container, and a piston contained in the storage container adapted to be actuated by the pressure developed in the combustion chamber so as to cause fuel to pass from the storage chamber into the combustion chamber. A firing block adapted to receive a cartridge containing slow-burning powder is provided on the combustion chamber. In the apparatus shown, an open-ended cylinder 1 is divided by a partition 3 into a combustion or decomposition chamber 2 and a fuel storage chamber 30. A casing 13 is secured at the combustion chamber end of the cylinder 1 and contains a diaphragm 15 having discharge nozzles 16, a bladed turbine wheel 18 and an electrical generator 21, 22. The fuel storage chamber 30 is closed by a wall 24 and contains a piston 22 carried on a rod 26. The fuel storage chamber is filled through a pipe 28 and fuel passes from the chamber through a duct 32 in which is a frangible disc 33 to an injection nozzle 5 in the combustion chamber 2- A heating and ignition device is disposed in the combustion chamber and comprises a cartridge 7 containing slow-burning powder which is fired electrically, the gases produced issuing through the nozzle 13a into the combustion chamber. Some gases pass through the nozzles 16 to drive the turbine 18 and some pass through the orifice 4 in the partition 3 and act on the piston 22, thereby causing fuel in the chamber 30 to flow through the duct 32 and after bursting the disc 33, to issue through the nozzle 5 into the combustion chamber. The fuel is caused to burn or decompose by the hot gases from the igniter cartridge 7 and the combustion or decomposition products flow to the turbine 18 and to the space behind the piston 22 so that the fuel supply is maintained. The fuel is a monofuel such as ethylene oxide or propyl nitrate. The apertured partition 3 may be omitted so that the piston 22 forms one end wall of the combustion chamber.

Further rings or washers 16 are provided between the ends of these bosses and the ends of the rotor, the rings being slotted to accommodate the inner edges of the vanes. The vanes are connected by rods with a circular head at one end, and with a reduced diameter at the other end, the latter fitting into a hole in a vane. The separate springs 11 may be replaced by a continuous spring contained by an annular groove. Pins 12, 18 prevent rotation of the rings 9, 16.

Title: Method of impregnating electrically conductive skeletons in particular sintered electrodes
IPC: H01M4/88
Filed: 1962-09-07
Abstract: A porous skeleton electrode, especially of the sintered type used in batteries and fuel cells, is impregnated with active constituents by electrodepositing the active metal from an electrolyte containing it in a complexed form, and also containing compounds reducible at a more positive potential than hydrogen, the pH exceeding 7 and preferably 9-12.  The skeleton metal is thereby not subjected to evolution of hydrogen and is not corroded by electrolytic action. Activating metals include Fe, Co, Pb, Cd, Hg, Ag, Cu, Mg, Zn, Mn, Ni, and Bi, which may be complexed by adding ammonia or an amine dissolved in water.  Compounds repressing the evolution of hydrogen are alkali metal nitrates, hydrogen peroxide, hypochlorites, chlorates, nitrites, quinone, and organic nitro-compounds.  The skeleton metal may first be subjected to vacuum before flooding with the electrolyte, or may be preimpregnated with oxygen.

Advantageously 1/2 a mol of reducing agent per mol of lactone is used in the case of a free 21-hydroxy compound and 3/4 of a mol in the case of a 21-ester, and the metal salt produced by the reduction is preferably acylated directly with an acid anhydride or halide. The ketal cleavage is preferably effected by heating with an aliphatic carboxylic acid in aqueous medium, and for the hydrolysis of the 21-acyloxy group an alkali metal carbonate or bicarbonate is preferably used.  Examples are given, an additional product of the reduction process being D 5-3:20 - bis - ethylenedioxy-11:18;18:21 - (bis-oxido)-pregnene.  In these examples 18:21-diacylates are separated from concomitantly formed 21-acylates by chromatographic methods, and both on heating, for example, with aqueous acetic acid, yield aldosterone-21-acylates, the d-, l- and dl-forms of which are referred to.  Mono- and di-acetates, formates, trifluoroacetates, propionates, trimethylacetates, cyclopentyl-propionates and phenylpropionates are described and an extensive list of further acylating acids is provided.
