Title: Manufacture of irones
Inventor: FORDHAM WILLIAM DOUGLAS
IPC: C07C1/22
Filed: 1961-04-07
Abstract: 1,3,3,4-tetramethylcyclohexene is prepared by reducing 1,3,3-trimethyl-4-formylcyclohexene, for example by first converting it by means of hydrazine to the hydrazone, which is then reduced to the hydrocarbon by means of alkali, or preferably, by heating it with hydrazine hydrate in the presence of potassium hydroxide and propylene glycol at 140 DEG C.  Specifications 755,667 and 761,686 are referred to.ALSO:A mixture of isomeric irones of the formula <FORM:0938763/IV(a)/1> where R is an alkyl group containing not more than five carbon atoms is prepared by a process comprising the following successive steps (a) reducing 1,3,3-trimethyl-4-formylcyclohexene (pseudocyclocitral) to give 1,3,3, 4-tetramethylcyclohexene, (b) heating a mixture of the 1,3,3,4-tetramethylcyclohexene with acetic acid, acetic anhydride and paraformaldehyde, e.g. at 190 DEG C. for 14 hours, and saponifying the mixture of isomeric 6-methylcyclogeranyl acetates thus produced to give the corresponding 6-methylcyclogeraniols, (c) oxidising the cyclogeraniols, e.g. by reaction with chromic oxide or by catalytic dehydrogenation or by the Oppenauer method to give a mixture of the corresponding isomeric 6-methylcyclocitrals, and (d) condensing the cyclocitrals with a ketone of formula CH3COR where R has the meaning given above in the presence of sodamide or sodium hydride or any other alkaline condensation catalyst.  Step (a) is preferably effected by heating the aldehyde with hydrazine hydrate in the presence of potassium hydroxide and propylene glycol at 140 DEG C. The 1,3,3-trimethyl - 4 - formyl-cyclohexene starting material may be prepared by oxidising a -pinene in the liquid phase to produce hydroperoxides, reducing the hydroperoxides to yield verbenol and thereafter pyrolysing the verbenol in the vapour phase with or without a catalyst.  The oxidation of a -pinene, in addition to verbenol, yields verbenone. 3-pinene-2-ols, pinene oxide and myrtenol, and the pyrolysis of verbenol, in addition to pseudocyclocitral, yields linonene-3- and 5-ols and pseudotagetone. Specifications 755,667 and 761,686 are referred to.

Patent GB-610398-A (GB)
Title: Electron discharge device
IPC: H01J31/06
Filed: 1946-04-26
Abstract: 610,398. Electron beam apparatus. WESTERN ELECTRIC CO., Inc. April 26, 1946, No. 12674. Convention date, May 2, 1945. [Class 39 (i)] In a high-speed switching device, an electron beam is arranged to scan a row of targets and an auxiliary electrode is provided to enable the targets to be impacted in certain sequences. In Fig. 2, 13 are the target electrodes and 14 the auxiliary electrodes; the latter is shown in detail in Fig. 3. The electrode 14 is secondary electron emitting and is therefore positively charged when impinged on by the beam; since the electrode is connected to the deflecting electrode 16 this positive charge will deflect the beam downwards in the Figure. There is an equilibrium position, a, b, c, d, e, under each finger 21 of electrode 14 for the electron beam; if it rises higher, the deflecting plate 16 is charged and the beam deflected downwards again; if it falls lower, 16 discharges through resistance 18 and the beam is deflected upwards again. Normally, the beam falls on the line O-O, Fig. 3; on the application of a suitable pulse to deflecting plates 24, 25, the beam moves over to the line X-X; 16 then starts charging until the beam takes up the equilibrium position f. When the pulse ends the beam returns to the line O-O and takes up position e. If a pulse of opposite polarity is now applied, the beam moves to the line Y-Y, 16 discharges and the beam takes up the position e<1>; when the pulse ends, the beam moves to d. The beam can thus be made to move upwards in steps, and can at any time be returned to e by a pulse sufficient to move the beam to X-X; alternatively, the beam can be returned to d by a pulse deflecting the beam on to 20B. When the beam is at a, b, c, d, e, the corresponding targets 13A, 13B, &c. are imparted. Thus, the targets can be scanned in several different sequences according to the pulses applied to 24, 25. In a modification, Fig. 4 (not shown), there are diagonal strips across the fingers 21a which enable the beam to be moved down by steps, as well as up, thus increasing the possible number of sequencies obtainable. In a further modification, Fig. 6 (not shown), an additional strip is placed under the upper finger 21a so that the beam is automatically returned to e after reaching a. Stepping speeds of 10 kcs./sec. are said to be obtainable.

Title: Improvements relating to apparatus for measuring the rate of flow of fluent material
IPC: G01F1/80
Filed: 1953-05-11
Abstract: 731,213. Rotary meters. WALLACE & TIERNAN, Inc. May 11, 1953 [May 10, 1952; April 13, 1963], No. 13155/53. Class 110 (2). [Also in Group XXIX] A rotary meter, Fig. 1, comprises an impeller 12 through which fluent material other than gases is fed and means for recording the rate of flow of said material which is responsive to the torque on the impeller shaft, the latter being driven at a constant speed about a vertical axis. The impeller is driven by a synchronous electric motor 24 through gears 25, 27, 28 journalled in a frame 30. The gear 27 is rotatably mounted in a lever 40 that is pivoted about an axis 41. The lever is coupled to the piston of a piston and cylinder unit which is connected to a source of pressure through a conduit 56 having a flow control valve 55 and a branch line 58 leading to a gauge 60. Movement of the lever is effected against the action of an adjustable spring 50 (see Fig. 2, not shown), in response to the variations in the flow of material supplied to the impeller 12, the lever in turn controlling the supply of pressure fluid to the piston and cylinder unit. Balancing may be effected by air under sub-atmospheric conditions or liquid under pressure in which case the piston is preferably replaced by a bellows. In a modification (see Figs. 7 and 8, not shown), the fluent material is fed through an impeller 120 and then passes through the space between members 101, 106 to the outlet conduit 103. The torque on the impeller is transmitted to the motor 116 and hence to its stator which is rotatably mounted for movement as a unit with a supporting plate 113; the latter, together with a bearing roller 125 and a lever 126, being moved in the counterclockwise direction by said torque. The movement of the plate 113 is transmitted through a coupling 147 to a lever 149 and operates a valve 144 in a closing direction (see Fig. 8, not shown). Closing of the valve increases the pressure in a conduit which is connected to the recorder and to a chamber 132, thereby contracting a bellows 136 and applying through a link 143, and a balancing torque in the clockwise direction on the lever 126.

Abstract: 289,894. Kruckenberg, F. May 5, 1927, [Convention date]. Look-out reflectors.-In order to permit high speed trains to operate with short time intervals between vehicles and to provide adequate warning signals to a train following the one in front at less than a full braking distance, each train is made to set in its rear a series of signals differing in character and extending over a braking distance, each signal being changed to one indicating a greater length of clear track as the first train proceeds ahead. The signals may be a group of lamps along each section for each signal and those for each signal may be of a distinctive colour. If lamp signals are used the following series is suggested, red for absolute stop signal, orange, dark yellow, yellow for slowing down signals, white for preparing or warning signal, and green for normal clear. The Specification as open to inspection under Sect. 91 (3) (a) states that the lamps on the track may be arranged to project images upon matt screens carried in the vehicles either directly or by a system of reflecting mirrors or prisms, an example of which is shown on Fig. 20 (Cancelled). In this arrangement, in order to provide for swinging of the vehicle of the mono railway, three mirrors 114, 115, 116 are arranged to direct the beam from the lamps 100 on the track, by way of rejectors 105, 106, to the screen 107. Alternatively, a curved mirror or prism may replace the three mirrors 114, 115, 116. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 19757/13, 124,201, and 163,597, [all in Class 105, Railway signals &c.].

[Also in Group II] In a method and apparatus for adding a continuously-controlled small proportion of filter aid to a liquid in flow irrespective of the pressure in the system, the main stream of liquid YX is by-passed through B into a vessel A having a slurry of filteraid in its lower portion at E. An annular chamber D freely movable with a clearance inside the vessel A rests on the slurry E and has an axial passage d<SP>1</SP> closed at its upper end and surrounding the tube B. The liquid flows from B down the annular clearance between B and D and across the slurry-liquid interface at the bottom of D, entraining some of the filter-aid between D and A and passing through a tube C to rejoin the main stream. The pressure-difference and the flow of liquid may be adjusted by the valves P, Q, R ; the apparatus (made, e.g. of glass) is then self-regulating for small changes. In a modification, Figs. 2 and 3 (not shown), the vessle D is additionally controlled by a metal armature at its lower end coacting with a magnet carried by a movable tube surrounding the vessel A.

Title: An improved method of regulating combustion in boiler furnaces and means therefor
IPC: F23N1/02
Filed: 1922-05-11
Abstract: 179,952. Smoot, C. H. May 11, 1921, [Convention date]. Air-supply, regulating. -Combustion in a steam-boiler furnace is regulated by varying the amount of air supplied to the furnace by a fan in accordance with changes in the pressure of steam in the boiler and in the pressure of the air supply. The steam pressure in the boiler 2, Fig. 1, acts upon a piston 9 and tends to lift a constant load 17 upon a diaphragm 15 mounted in the chamber 18 and is assisted by the differential pressure of the air supplied from the blast conduit 7 through the pipes 20 and 19 to the upper and lower sides of the diaphragm 15. Upward move. ment of the diaphragm actuates, through relay apparatus 13, the valve 6 controlling the supply of steam to the engine 3 driving the fan 4 supplying air beneath the grate 1. In the modification shown in Fig. 3, air-supply and exhaust fans 3, 4 are controlled by varying the steam supplied through the valve 34 to the fan engines 5, 6 in accordance with the changes in boiler pressure and the difference in pressure at the fans. Steam pressure from the boiler acts through the pipe 11 upon a diaphragm 9 loaded by the spring 13 and is assisted by the differential air pressure acting on the diaphragm 23 connected by the lever 18 and link 17 to the diaphragm 9. Down. ward movement of the diaphragm 23 caused by increase in the differential pressure on the diaphragm actuates, through the rod 42 and arm 29, a valve 28 reducing the pressure of steam above a differential piston 26, due to the effect of a throttling-valve 48, and causing the piston to actuate the link 30, lever 31 and rod 33 and close the valve 34 supplying steam to the fans. The differential piston 26 is connected to the rod 42 through a dashpot 39.
