Abstract: 1,224,346. Photographic contact printers. ADDRESSOGRAPH-MULTIGRAPH CORP. July 15, 1968 [July 31, 1967], No.33660/68. Heading G2A. A photographic contact printer is provided with a control circuit such that, when the machine is turned on, the printing lamp 24 is first caused to warm up to a high (or operating) intensity level, and then the machine is placed in a standby condition with the lamp operating at low brilliance until an original is inserted, when the lamp is returned to the high intensity level. A time delay device returns the machine to the standby condition after a copy is made. The printer is provided with a blower to cool the lamp, which blower does not operate during the warming up period, operates at a reduced speed during standby periods and at full speed while a copy is being made. A drive motor and transport system operate at reduced speeds during standby periods, and at increased adjustable speeds during copying periods. Copying Sequence Insertion of an original between guides 42, 44 trips a switch arm 192 to start the control circuit energizing the lamp, blower, motor and transport system to their copying states. In the stand-by state, a copy sheet 16 is positioned with its leading edge engaging an arm 182. The closure of switch arm 192 causes an idler roller 52 to engage a driven roller 50 and the copy sheet is advanced into contact with the original. The two are then advanced to a rotating drum 22 and flexible guide assembly 30 where the copy sheet is exposed. The two sheets are then separated by vacuum chests 70, 72, the blower motor providing the suction therefor, and the original leaves the machine while the copy sheet passes to a developer unit where it is wetted with developer liquid in a tray 94 by the action of rollers 90, 96. The developed copy sheet is fed out to a receiving tray 36. When the machine is off, the rollers 90, 96 are disengaged. They are rotated slowly when the machine is in the standby state.

Title: Improvements in or relating to drinking water containers for poultry or animals
IPC: A01K39/024
Filed: 1968-07-17
Abstract: 1,236,234. Poultry drinker. POLY-MATIC FOUNTAIN Inc. 17 July, 1968 [17 July, 1967; 18 Aug., 1967], No. 34076/68. Heading A1M. A drinking device having an automatic, float operated, liquid level adjustment comprises a trough 10 having a float receptacle part 12 and a peripheral drinking trough 11. Annular float 30 carries a liquid weight vessel 29 through which a valve depressor cap 44 is held via a threaded adjusting bolt 40. Mains water is fed into valve chamber 14 via inlet 13 and flows into receptacle 12 when depressor cap 44 presses downwardly on the shaft of valve plunger 38 against the upward force of spring 37, and unseats valve seat 58. On sufficient water entering receptacle 12 the buoyant force of float 30 lifts depressor cap 44 and closes the valve. If the drinking device is tilted, float 30 and cap 44 remain horizontal and valve chamber 14 will tilt away from the lower surface of cap 44, and due to its indented frusto-conical shape the valve will close. This motion is enhanced by the sloshing effect of liquid in 29. The device also comprises a releasably secured conical cover 60, from which the device may be suspended from the ceiling by means of a levelling plate attached to cover 60. The water enters trench 11 from receptacle 12 via a flap type non return valve in the sloping wall of said trough. In a second embodiment the liquid water weight is contained in hollow portions of the float 30 and container 29 is dispensed with.

Title: Tunnel or enamelling pottery kilns
IPC: F27B9/08
Filed: 1928-11-21
Abstract: 325,794. Electric Furnace Co., Ltd. and Millar, W. J. Nov. 21, 1928. Resistance furnaces.-In tunnel kilns heated by resistance coils arranged horizontally in the refractory walls at different vertical levels the coils may be independently connected as required to produce a required temperature gradient in the vertical direction of the tunnel. The resistances are preferably of varying length to allow of variation in the temperature gradient in the longitudinal direction. In a double track kiln for firing pottery, groups of resistances E<1>, E<3> displaced towards the respective inlet ends of the track are arranged in the side walls, and a group E<2> are arranged in grooves in a central panel formed by firebricks threaded on vertical rods of nickel-chrome. Partitions D are arranged on the centre line adjacent the groups E', E<3>. Auxiliary sets of resistors N', N<2>, N<3> are interspersed among the resistors of the sets E', E?, E<3>. The main and auxiliary sets are connected through among the resistors of the sets E<1>, E<2>, E<3>. The switches O<1>, O<2>, O<3> for the auxiliary sets are controlled automatically by a thermostat P cooperating with contacts in a circuit comprising a battery Q and a relay q operating a switch R in the circuit of a coil S adapted to operate the switches O<1>, O<2>, O<3>. The resistances on each set of coils are connected permanently at one end to a bus-bar connected to the neutral point and at the other end may be independently connected to a bus-bar connected to either a main or auxiliary switch. The brickwork of the roof and side walls is recessed at intervals J as shown in Fig. 4 to prevent air draughts along the kiln when the end doors are open. Air inlets I controlled by dampers, and outlet flues H in the raised portion of the roof cause a transverse draught. Chambers fitted with counterweighted side doors and transfer trucks are provided at the ends of the kiln to facilitate charging and discharging and signal lamps are provided to enable the operators to work in synchronism. The trucks are propelled by an electric motor driving a rack through a pinion. The motor is fitted with a clutch which slips at a given load, for example, if a truck meets an obstruction.
Patent GB-945162-A (GB)
Title: Improvements in or relating to the preparation of aryl alkyl aminoketones
IPC: C07C45/63
Filed: 1959-10-09
Abstract: <PICT:0945162/C2/1> Aminoketones of the general formula: <FORM:0945162/C2/1> (wherein R represents hydrogen or an alkyl group and R2 and R3 represent alkyl groups, which may be alike or different, or together with the nitrogen atom form a 5 or 6 member heterocyclic ring) are produced by continuously feeding an alkyl aryl ketone having at least one hydrogen atom attached to the alpha carbon atom of the alkyl group, and a halogen to a closed reaction vessel, continuously removing the hydrogen halide formed, effecting the halogenation in a forced cycle with continuous removal of part of the halogenated product, continuously reacting the withdrawn halogenation product with a secondary amine and treating the reaction mixture with an aqueous alkali metal hydroxide solution, and continuously removing the fixed halogen hydracid. Preferably the reaction mixture is pumped through the cooled interior of a jacket vessel within the closed reaction vessel under the action of light.  As shown, halogen is fed through pipe 15 and ketone is fed through pipe 16 into a reaction chamber 10. The agitator 13 causes the reaction mixture to circulate through the jacket vessel 11 and the annular space between that vessel and the wall of the chamber 10.  Cooling liquid is passed through coil 12.  Gaseous hydrogen halide which is formed is discharged through pipe 17, and halogenated product is removed through pipe 18.  The halogenated product passes to a further vessel where residual hydrogen halide is removed by washing with water or by degassing at a higher temperature preferably under vacuum. The halogenated product is then passed to a reaction vessel in the form of a long horizontally arranged container provided with stirring arms and is mixed with a secondary amine.  The mixture is then treated with soda lye at the end of the same vessel or in a further vessel, and the amine phase is then continuously separated from the aqueous phase. As secondary amines these may be used diethylamine, piperidine, piperazine, pyrrolidine, or morpholine.  Examples describe the continuous bromination of propiophenone and the amination of the brominated product with diethylamine and pyrrolidine.  Reference has been directed by the Comptroller to Specification 849,755.

Filed: 1971-07-23
Abstract: 1355267 Purifying I C engine exhaust gases TOYO KOGYO CO Ltd 23 July 1971 [24 July 1970 31 July 1970(4)] 34635/71 Heading F1B A jacket 10 surrounding the shell 6 of an afterburner 5 is supplied with cooling air and air is also supplied to the afterburner chamber 7. The flow of cooling air is controlled in response to the temperature of the shell 6, the engine body, the engine cooling medium or the jacket casing 9 and/or the speed of the engine and the flow of afterburning air may be controlled in response to engine speed. The air may be supplied by a single engine-driven pump 13 or separate pumps may supply the cooling and afterburning air. In the embodiment shown, the flow of air to the engine exhaust passage 8 is controlled by a valve 19 which is open in a lower engine speed range and closed above the range, the air flowing through a non-return valve 20. Cooling air flows to the jacket 10 through a valve 21 at a rate proportional to engine speed in a lower speed range when a valve 27, which is open above a predetermined temperature detected by a sensor 29a, is open. Above the speed range a valve 22 is open and the valve 19 closed. A valve 24 releases a proportion of the air to the atmosphere at a predetermined air pressure. A non-return valve 25 prevents the flow of exhaust gas from the chamber 7 to the cooling air supply passages. The valve 27, Fig. 12 (not shown), may be disposed between the jacket and both valves 21  and 22. The valves 19 to 21 may be combined in a single assembly, Fig. 15, the valve member 39 and seat 42b providing the valve 19, the valve member 43 the valve 20, the opening 39a and valve member 40 the valve 21 and the valve member 39 and seat 45 the valve 22. A solenoid valve 46 is opened by an engine speed detector 47 below a certain speed and the suction in the engine intake passage 3 is applied to the diaphragm 36 to seat the member 39 on the seat 45. In this condition, with the valve 24 closed, air flows past the valve members 40 and 43 and with the valve 24 open the air escapes to atmosphere. With the valve 46 closed the valve member 39 is seated on the seat 42b and unless the valve 24 is open all the air flows to the passage 18 communicating with the jacket 10. Various other relationships between the air flows to the jacket 10, the chamber 7 and the atmosphere are described.
