When an acyl group is present, it may be removed from the product by saponification; a carboxylic (ester product may be similarly treated. Examples are given of the hydrogenation of (1) ethylaniline and dimethylaniline to the corresponding hexahydro compounds, and reference is made to the same treatment of homologues, such as ethyl-o-toluidine, diethyl-p-toluidine, and the corresponding xylidines; (2) 2-acetylaminonaphthalene-3-carboxylic acid ethyl ester (obtained by acetylating the amino compound) to 2-acetylamino.3-ar-tetrahydronaphthoic acid ethyl ester, 1-acetylamino-2-naphthol ethylether to ar-tetrahydro-1-acetylamino-3-naphthol ethylether. and 1- acetylamino-7-naphtholmethylether (obtained by methylating the naphthol) to ar-tetrahydro-1- acetylamino-7-naphthol methylether; the products are saponified in each case. Specification 276,571 is refferred to. Azo dyes. - ar-Tetrahydro-1-amino-2-naphthol ethylether couples with p-nitrodiazobenzene to a yellowish, and with diazoazobenzene to a brownish red dyestuff; its diazo compound couples with 2-naphthol-3 :6-disulphonic. acid to a pink dyestuff. The diazo compound of artetrahydro-1-amino-7-naphthol methylether combines with 2-naphthol-3 : 6-disulphonic acid to a yellowish red dyestuff, whilst the ether itself couples with p-nitrodiazobenzene to a brownishred dyestuff.

Title: Improvements relating to the heating of buildings
IPC: F24H3/00
Filed: 1926-05-11
Abstract: 252,357. Humphreys & Glasgow, Ltd., (Assignees of Vincent, G. 1.). May 21, 1925, [Convention date]. Air-heating furnaces. - In an installation for heating buildings by means of hot air, a solidfuel furnace is adapted to be alternatively heated by a gas burner, the products of combustion from which pass through a heat economizer, means being provided for by-passing the heat economizer when burning solid fuel. The air-heating furnace 1 having hot-air distributing-pipes 22 is provided adjacent the ashpit 19 with a gas burner 18 carried by a swinging connection 15 from a gassupply pipe 14. Normally solid fuel is burnt, the products of combustion passing direct to the chimney 7 by a pipe 8, but when a lesser degree of heating than usual is required the burner 18 is lit and swung into the ash-pit which may then be closed; the products of combustion are then partly utilized in the furnace 1 and pass by a valved pipe 10 to the economizer 3, a, valve 9 in the pipe 8 being closed. The economizer comprises three banks of triangular tubes 12 through which the products of combustion pass in series being supplied by the pipe 10 to an end box 24 with a baffle 25 and withdrawn from an opposite end box 23 by a valved pipe 11 communicating with the pipe 8. Cold air enters through an opening 13 in the base of the economizer and passes around the tubes 12 and through a distributor 5. Water vapour condensed in the economizer is withdrawn bv a drain cock 22. The valve 16 of the gas-supply pipe may be controlled by a thermostat 21 and a connection 17 may be provided for a pilot light.

Abstract: 947,010. Fluid-pressure servomotor control systems. CHERRYBURRELL CORPORATION. March 30, 1962 [April 4, 1961], No. 12256/62. Heading G3P. [Also in Division G1] The level and density of a liquid in a tank 12, Fig. 2, is sensed by a diaphragm 26 in the tank wall and supported upon a member 28 with a recessed face so forming a chamber 30; the member 28 incorporates an air inlet 32 and a bleed outlet 38 respectively leading into and away from the chamber 30. In the outlet 38 is threaded an insert 36 the outer end of which is arranged a small distance from the diaphragm. The liquid in the tank deflects the diaphragm 26 so that it closes the outlet 38 until the air pressure from the inlet 32 builds up a pressure sufficient to unseat the diaphragm from the outlet 38 to permit a bleed therethrough. Air is supplied to the inlet 32 via a diaphragm actuated pressure-regulator 44, Fig. 1, the movable closure member 48 of which is opened by a spring 60 and air pressure downstream of a restrictor 54 acting on the diaphragm in opposition to the air pressure upstream of the restrictor. Further downstream of the latter is a branch 62 leading to a monometer 64 or a pressure gauge 66 which may be calibrated to read directly the liquid level or quantity in the tank; this branch also includes high and low pressure switches 68 controlling an alarm or a pump supplying the tank. The outlet 38 is connected to exhaust either through a restriction or a back pressure regulator 72, the movable closure member 78 of which is connected to a diaphragm 82 urged towards the valve closed position by air pressure in a branch 86 from the air inlet, between the restrictor 54 and branch 62, in opposition to a spring 88 and the bleed pressure in the outlet 38.

Title: Process for catalytically producing carbon disulphide from sulphur vapour and gaseous hydrocarbon
IPC: C01B31/26
Filed: 1963-03-23
Abstract: Carbon disulphide is produced by heating sulphur vapour and gaseous hydrocarbons in the presence of charcoal as a catalyst. The gaseous hydrocarbons, e.g. methane, and sulphur in vapour form may be mixed and preheated before contact with the charcoal. The reaction is effected at a temperature of 500-900 DEG  C. and a space velocity of 120-1400 may be used.  At least stoichiometric proportions of sulphur vapour may be employed.  In an example, methane (25 Kg./hr.) and sulphur (200 Kg./hr.), mixed and preheated to 500 DEG  C., were passed into a reactor at 800-820 DEG  C. containing 400 Kg. charcoal. Exit gases were desulphurized and cooled to 0 DEG  C.  Uncondensed carbon disulphide was absorbed by washing the gases with mineral oils and hydrogen sulphide was transferred to an oxidation furnace.

[Also in Group VI] In an electric toaster or the like, the main switch, Fig. 2, comprises fixed contacts 1b and a contact bridge la rigidly connected to a switch lever 24 biased by a spring to the off " position 24a. Lever 24 is held in the on " position by a spring-biased locking lever 23. An armature 29 is pivoted at 30 and biased by spring 31 so as to engage abutment 25 on lever 23. Lever 24 is released when electromagnet 9 is energized to attract armature 29 which then knocks projection 26 on lever 23 to release lever 24. A series of contact pairs 3, 4, 10, 8 are mounted on a carrier 13 and the corresponding contact bridges are mounted on a rod 14 biased downwardly by spring 15. The rod 14 is lifted by a spring-biased armature 16 pivoted at 17 when electromagnet 11 is energized, the armature and hence rod 14 being held in position by engaging a projection 21 on a spring- biased lever 19. A bimetallic strip 5 connected in the heating current circuit controls the energization of electromagnets 9 and 11. When electromagnet 11 I is energized it attracts armature 16 to lift rod 14 which disconnects the pairs of contacts 3 and 10 and connects pairs of contacts 4 and 8. Thereafter, when electromagnet 9 is energized, lever 24 is released and, as it rises, it strikes lever 19 which releases armature 16. This allows rod 14 to return to its lower position.

Title: Improvements in butter serving machines
IPC: A01J21/02
Filed: 1944-06-30
Abstract: 585,042. Extruding butter and cutting it into pats. THOMAS, S. A. June 30, 1944, No. 12505. [Class 87 (ii)] , Butter is forced from a tube 11 by a piston 16 through an orifice 15, and is cut into pats by a wire 55 which sweeps across the orifice. The piston is depressed intermittently, and the wire is traversed across the orifice, by rocking a handle 35 which is keyed to a cam shaft 32. The shaft depresses a pawl 24 which engages teeth 30 on the piston rod 17 and depresses the latter against the pull of a spring 45, and simultaneously a drive is transmitted through gears 56 57, and a clutch and shaft (not shown) to rock the frame 53 (which carries the wire 55) against spring action. When the handle 35 is released, the pawl is disengaged by a spring 26 and a spring detent 36 moves in to engage teeth 30 and hold the piston down. The piston, handle and gears are carried by a cover 4 hinged to a casing 1 at 7, and the cover is held down by latches 22, 23 which engage grooves in the top of posts 8 threaded into the base of the casing. When the tube 11 is empty, as shown in Fig. 5, the piston is released by disengaging the latch 23, this disengaging movement being transmitted by stud 43 and an arm (44, not shown) to the pawl and detent to release them from the teeth 30. The spring 45 then raises the piston and the cover may be opened. When the piston rod 17 rises, it uncovers a vent 48 in the piston 16 and, by means of links 49, tilts the piston, so that any suction is prevented. An ice chest is accommodated in the housing.
