Abstract: 839,068. Spits; illumination and observation devices. ROTISS-O-MAT Ltd. (Harley Manufacturing Co.). Oct. 9, 1958 [April 24, 1958], No. 13046/58. Class 28 (1). [Also in Group XI] Spits 15, for roasting chickens or the like, extend between and are detachably mounted on two end discs or plates 9, 10 fixed on a central power-driven spindle 11 within a casing, an electric heating device being arranged in the casing adjacent said spits. The apparatus comprises a cabinet with a lower section 2 for keeping cooked chickens hot and an upper section 1, with a metal casing 3 having windows 4 and a door 5, which contains the metal end discs 9, 10 and spindle 11 driven by an electric motor. As shown, there are seven spits, each consisting of a metal rod 15 pointed at one end to pass through chickens 16 which are prevented from rotating about the spit by a U-shaped member 17, slid on to the spit and secured by a thumb-screw 18. A detachable end member 19 which passes over the free ends of member 17 is secured on the spit 15 by thumb-screw 20 and the pointed end of spit 15 passes through an aperture in disc 9. The end of spit 15 remote from the pointed end is threaded and inwardly of the thread is provided with a planet pinion 22 which meshes with a stationary sun pinion 23 so that, as the drum rotates each spit is rotated. The spits are placed in position by sliding a reduced part 24 on each into a keyhole slot in the edge of disc 10 until the enlarged end of the slot is reached when bushing 26 slides into the slot and is held by a sleeve 28 secured by a thumbscrew 29 over the reduced part 24 of the spit. Two U-shaped metal encased infra-red elements are provided which may be thermostatically controlled and the interior of the casing is lit by a tubular quartz lamp. The bottom of the casing is constituted by a drip tray 34. An automatic timing device may be provided to give audible warning when the chickens are cooked. A micro-switch 41 is provided in the heating circuit which is only closed when a door 35 in one end wall is closed. This door gives access to the threaded ends of the spits so that a handle 37 may be screwed on to this end of one of the spits and, after loosening sleeve 28, the pointed end of the spit may be disengaged from disc 9. This end is held by a hook 38 so that the spit may be lifted out and placed in the lower heated compartment.

Abstract: 729,925. Automatic voltage control systems. ROTAX Ltd. July 2, 1953 [May 26, 1952], No. 13245/52. Class 38 (4). In Fig. 1 the voltage of a generator to be regulated is applied to a bridge circuit including a gas discharge tube d so that voltage deviation results in an input to an amplifier e to correct the deviation by energization of a winding f of a carbon pile regulator g in series with the generator field m. To compensate for the effect of change of resistance of winding f with temperature, a winding h having a positive temperature coefficient, responsive to the temperature of winding f, is included in the bridge circuit Winding h is also arranged to be inductive to minimise transient changes in winding f. Gas discharge tube d may be replaced by other forms of non-linear resistance and winding h connected in another arm of the bridge. In other modifications the bridge circuit is replaced by a pair of separate input circuits one of which includes a non-linear resistance.

Filed: 1949-05-18
Abstract: 660,935. Digester screws. AMERICAN VISCOSE CORPORATION. May 18, 1949. [June 22, 1948] No. 13285/49. Class 78 (i). An apparatus for treating solid materials comprises a vessel having a side-wall of circular cross section and end walls, a helical conveyer positioned within the vessel coaxial with the said wall or walls and having helices of a pitch in each of the end portions of the conveyer which is less than the pitch of the helices in the middle portion of the conveyer there-between, the helical vane of the conveyer being continuous from end to end thereof, and having the entire length of its radially outer edge in close proximity to the interior surface of the vessel and its end edges in substantial contiguity with the end walls of the vessel, and an aperture in each end wall, the material being fed into the vessel through one aperture and out of the vessel through the other aperture. Fig. 1. Material is fed and compressed into vessel 9 by screw 17 and is conveyed therethrough by screw 10. The pitch of helices 11a thereof increases so that the material expands and reacting fluid is then introduced at 20 and the whole is conveyed through the vessel 9 whilst being mixed by agitators 11 secured to screw 10 and then compressed by decreasing- pitch helices 11b and discharged at 22, preferably by a screw (not shown). The speed of the smaller screws can be varied to vary the compression of the material, which compression serves to seal the gaseous products from the atmosphere. Thus alkali cellulose can be treated with carbon disulphide to produce xanthate cellulose.

Title: An improved process for producing complex metal compounds of pyridine carboxylic acids containing one or more sulphhydryl residues
IPC: C07D213/79
Filed: 1931-05-05
Abstract: Mercaptopyridine carboxylic acids are converted into metal (other than alkali or alkaline-earth metal) compounds containing the metal in the mercapto groups by the reaction of metal oxides, hydroxides, or salts upon the carboxylic acids or their alkali metal salts; where a metal salt and an alkali metal salt of the acid are used, the process is effected in presence of sufficient alkali to produce the metal hydroxide.  The resulting salts may be precipitated from the solution by means of organic solvents such as alcohol or acetone, or the solutions may be acidified to give the free acids.  The acids may be converted into salts by treatment with alkalis or organic bases such as pyridine. Examples describe the preparation of the lead sodium and copper sodium compounds of 2-amino-6-thiopyridine-4-carboxylic acid, the lead potassium, lead diethylamine, cadmium potassium, vanadium sodium, arsenic potassium, copper potassium, silver sodium, tin sodium, bismuth ammonium, cadmium choline, arsenic pyridine, bismuth methylaniline, and gold sodium compounds of 2 : 6-dithiopyridine-4-carboxylic acid, the lead sodium and arsenic sodium compounds of 2 : 4 : 6-trithiopyridine-3-carboxylic acid, and the gold sodium compound of 2 : 4-dithiopyridine-3-carboxylic acid.  The lead compounds are of value in the treatment of cancer. 2-Amino-6-thiopyridine-4-carboxylic acid is prepared by the action of alcoholic potassium sulphydrate on 2-amino-6-chlorpyridine-4-carboxylic acid.  2 : 4 : 6-Trithiopyridine-3-carboxylic acid is prepared by hydrolysis of the nitrile of 2 : 4-dioxy-6-chlorpyridine-3-carboxylic acid, replacement of the two hydroxyl groups by chlorine, and treatment of the trichlorpyridine carboxylic acid with alcoholic potassium sulphydrate.  2 : 4-Dithiopyridine-3-carboxylic acid is prepared by converting 2 : 4 - dioxy - 3 - cyanopyridine into 2 : 4-dichlor-3-cyanopyridine, hydrolysis to the carboxylic acid, and treatment with alcoholic potassium sulphydrate.
