Title: A dampening system for a rotary offset lithographic printing machine
Inventor: HEINRICH B
IPC: B41F33/00
Filed: 1971-04-20
Abstract: 1284696 Automatic thickness control MASCHINENFABRIK AUGSBURG-NURNBERG A G 20 April 1971 [6 May 1970] 10254/71 Heading G3R The thickness of a layer of dampening liquid on a printing machine cylinder is maintained constant by controlling the supply of liquid to the cylinder in dependence on a measurement of thickness made without contact with the liquid. In Fig. 1, dampening liquid for a plate cylinder 1 of a rotary, offset, lithographic, printing machine is supplied from a tank 23 through a filter 25 and valves 27, 13 to nozzles, such as 5, in which it is subjected to airpressure from a conduit 18 applied through a pressure reducing valve 17 so that the liquid is sprayed in the form of overlapping flattened jets between a roller 4 and a distribution cylinder 3 from which it is transferred to plate cylinder 1 by a forme cylinder 2. The liquid is supplied to tank 23 from a container 21 by a pump 22 which is started whenever the level falls in tank 23. Compressed air is supplied to conduit 18 by a compressor 15 through a water separator and filter 16. The thickness of dampening liquid on plate cylinder 1 is measured at 28 by a photo-cell, responsive to the intensity of infrared radiation reflected by the liquid, the output of which is applied through an amplifier 31 and compared with a reference voltage corresponding to a desired thickness so that errors exceeding predetermined values operate a relay circuit 33 and thereby actuate a reversible servomotor 14 in the appropriate direction to correct the thickness by adjusting valve 13 to alter the flow of liquid. The nozzles are raised to spray between cylinders 2 and 3 when plate cylinder 1 is rotating in the reverse sense. Valve 27 serves to shut off the supply of liquid when the printing machine stops. The nozzles may be cleaned by compressed air supplied from conduit 18 through a conduit 19.

Title: Improvements relating to the automatic control of aircraft
IPC: G05D1/00
Filed: 1936-04-08
Abstract: 477,984. Fluid-pressure servomotor-control systems. SPERRY GYROSCOPE CO., Inc. April 8, 1936, No. 10347. Convention date, April 9, 1935. [Class 135] In an automatic pilot for aircraft with simple or compound elevating rudder, means for maintaining level flight comprise a main servomotor controlled by gravitationally responsive means, a second, slow-moving, servomotor for changing the relation between the aircraft, the gravitational means, and the whole or part of the rudder, and means both for varying the direction of movement of the second servomotor in accordance with the direction of the force applied by the first servomotor to the rudder and for stopping the said change of relation by the second servomotor when the force applied by the first servomotor is zero. In the Figure, a gyroscope 1, operating as described in Specification 416,813, [Group XXXIII], differentially uncovers ports 2, 3 connected to a differential pressure valve or diaphragm 4 actuating a valve 5 controlling oil-pressure admitted to the main servomotor 6, the piston of which is connected to the elevator 10 and to a handcontrol 7 by cables 8, 9, and to the part 15 of the gyroscopic control by follow-up cables 11, 12 and lever 71. The second servomotor 21 is connected to the pipes leading to the ends of the first servomotor, through inletrestricting needle valves and free-returnspring-pressed outlet valves, and its piston is connected in the follow-up system by cables 13, 14 and the lever 71. Where the elevating rudder is of the Flettner type, Fig. 2 (not shown), the second servomotor is connected to the auxiliary portion and to the hand trim control, sustained load being taken off the cables 8, 9. With separate main and auxiliary elevators, Fig. 3 (not shown), the second servomotor adjusts the auxiliary through a nut and screw with, if desired, a multiplying belt arrangement, Fig. 4 (not shown). The byepass 56 in the main servomotor, enabling the rudder to be moved by hand when the automatic pilot is thrown out, also byepasses the second servomotor. U.S.A.

Patent GB-473149-A (GB)
Title: Improvements in or relating to thermionic cathodes producing a directed electron beam
IPC: H01J29/48
Filed: 1936-04-08
Abstract: 473,149. Thermionic cathodes. ZEITLINE, V., ZEITLINE, A., and KLIATCHKO, V. April 8, 1936, No. 10389. Convention date, April 8, 1935. [Class 39 (i)] A thermionic cathode structure producing a directed electron beam is mounted inside an electric discharge device so as to be isolated from atmospheric pressure and the cathode is supported immediately adjacent its heated emissive surface by supports, expansion of which is freely permitted transversely to the direction of electron emission whereby thermal expansion of the structure is taken up by the supports in a transverse direction and the emissive surface is maintained substantially accurately in its axial position within the device. In the form shown in Fig. 1, an insulating tube 1 carrying the cathode 3 is mounted transversely within the anode 7, its ends projecting through apertures therein and engaging spring fingers 20, 21 which permit transverse expansion of the tube. 6 is a control electrode. In a modification the heater is bent into a hairpin to reduce its magnetic field and passes through two parallel insulating tubes bound together by metallic ribbons at the ends. The cathode may be replaced by a wire wound helically over the tubes and coated with emissive material. In another form a pot-shaped cathode is supported on transverse bars mounted at the ends similarly to Fig. 1, and four short heating tubes are inserted in a pocket at the back of the cathode. In another method, a transverse heater tube is supported at the ends by pillars mounted in a yieldable disc, for example of mica, which fits within an anode. In Fig. 6 a pot-shaped cathode 3 has a radially extending flange 3a which is clamped between two insulating members 14a, 14b, the heater being inserted in the recess 3b. In Fig. 7, the cathode tube 1 extends in an axial direction, and the emissive surface 5 is coated on the inside at one end. Rigid rods 16, 17 adjacent the surface 5 are arranged to expand freely in a transverse direction. Further support rods 16a, 17a are similarly mounted but are also flexible to take up axial expansion of the tube.

Title: Improvements in and relating to automatic record changing talking machines
IPC: G11B17/02
Filed: 1945-04-25
Abstract: 607,600. Toothed gearing. THORENS SOC. ANON., H. April 25, 1945, No. 10426. Convention date, July 11, 1944. [Class 80 (i)] [Also in Group XXXVIII] In a toothed gear with cyclically variable ratio, used in a magazine gramophone to extend the time period between successive records, two identically cut gear-wheels 7, 8 are mounted closely together on a shaft 4 carrying a cycling cam 5, Fig. 2, which performs one complete revolution at each record-changing cycle. The lower gear-wheel 8 is mounted freely on the shaft 4, while the upper gear-wheel 7 is fixed and provided with a raised sector 71 which is sufficiently displaced to avoid engagement with a pinion 12 driven by a motor via a pinion 6, Fig. 1. The sector 7<1> is disposed at a part of the gear-wheel 7 such that it reaches the pinion 12 soon after the commencement of rotation of the cycling cam, i.e., during the period that the pick-up arm is lifted and moved outwardly across the record. A shaft 18, having a pinion 17 fixed to it, is arranged to be axially displaceable by a manually operated lever 20, so that in the upper position the pinion 17 will only engage the gearwheel 7, including the raised sector 7<1>, but in the lower position it will also engage the gearwheel 8. During a cycle of operation when no pause is required, the pinion 17 is set to engage both gear-wheels 7, 8, when the shaft 4 will revolve at a uniform speed without interruption, even when the raised sector 7<1> is passing the pinion 12. If, however, the pinion 17 is set to the upper position, the drive to the shaft 4 is interrupted when the raised sector 7<1> reaches the pinion 12, but a resilient arm 25 fixed to the underside of the gear-wheel 8, which continues to revolve, engages at each revolution one tooth of a star wheel 24 mounted on and fixed to the shaft 18, thereby causing the shaft 4 to be rotated through a small angle. The movement of the pinion 12 is therefore transmitted at reduced speed to the shaft 4 until the sector 71 has passed the pinion 12, or until the shaft 18 is set back to the lower position.

[Also in Groups XI and XII]  A jet engine for propelling a surface or submerged vessel and shown in sectional elevation in Fig. 2, includes a combustion chamber comprising a substantially hemispherical head portion N, mounted inside the vessel and a tail portion E, protruding aft of the vessel, the tail portion having a forward end matching the base of the head portion and then tapering to a smaller  area at the discharge end, the centre line of the tail portion sloping downwardly in a rearward direction from the forward end and curving gradually to a horizontal direction. The after end of the tail portion tapers outwardly in plan view as shown in Fig. 6 and terminates in an orifice O shaped as shown in this Figure and in the end elevation shown in Fig. 7. The section at JJ is circular and constriction of the orifice occurs along the lines TT. The combustion chamber, Figs. 2 and 5, comprises an inner shell with a refractory lining E<SP>3</SP> and an outer casing E<SP>2</SP> separated from the inner shell by heat insulation E<SP>1</SP>. The wall of the head portion is provided with cavities L for preheating the fuel supply to a spray nozzle 6 and cavities M for cooling water which afterwards passes to a preheating coil 13 connected to a series of spray nozzles 15. Combustion is supported by air or oxygen obtained by decomposition of an oxygen-yielding fluid, e.g. H 2 O 2 . The air or fluid is supplied to a preheating coil H terminating in a nozzle g<SP>1</SP>. The nozzle injects a spray into the interior of a hollow body I provided with a central outlet nozzle g2 and a ring of outlet nozzles I<SP>2</SP>. A deflector g<SP>3</SP> is arranged in front of the entrance to nozzle g<SP>2</SP>. The body I and coil H are arranged in a shroud K and a carbon ring 3 on to which the fuel is sprayed is secured to the outside of the body. Starting is effected by means of an auxiliary fuel supply 4, an oxygen supply 2, and an ignition plug Q. The water sprays from nozzles 15 enter ducts formed between plates 16 and are converted into steam. When not in operation the chamber contains water p<SP>1</SP> up to the level Xl and air P trapped above the water level. Upon cessation of use compressed air is supplied from 10 to the chamber to prevent the water entering therein from rising above the level X<SP>1</SP>. Specification 734,484, [Group XXXIII], is referred to.

Filed: 1940-06-15
Abstract: 541,900. Lubricating valves. EDWARDS, F. C. June 15, 1940, No. 10432. [Class 7 (ii)] The supply of oil for lubricating the upper part of the sleeve valve and cylinder is timed and metered by the valve-operating mechanism. Oil flows from the hollow valve-actuating shaft 17 through passages 22, 23, 24 and pipe 25 to an outlet 26 in the cylinder wall. The point 26 is arranged above the lowest position of the upper edge of the sleeve valve, and the oil is delivered therethrough when the sleeve is in its lowest position. Where the valve-actuating crank 18 is secured on its shaft 17 by serrations 27, one of these may be cut away to form an oil pocket which registers with the passage 23 as the shaft rotates. The oil may be supplied to a longitudinal groove formed in the cylinder wall as described in Specification 541,735.

Abstract: 771,909. Welding by fusion. CATERPILLAR TRACTOR CO. April 12, 1955 [Feb. 1, 1955], No. 10434/55. Class 83 (4). In order to seal the channel between two fillet welds joining the edge of one plate to the face of a second plate, the second plate is per. forated to expose the edge of the first plate and the welds and the perforation is filled with weld metal. In fabricating a part of a frame of a tractor having central oil containing compartment containing gearing and two outer dry compartments containing the steering clutches and brakes, front plate 13, Fig. 1, is joined by external welds 33, 34 to bottom and top plates 21, 14, respectively. The top plate 14 is partially lapped across the edge of back plate 16 as shown in Fig. 7, and an external weld 35 is deposited. Recesses 63 in the top plate 14 ensure that when an internal weld such as 42 is made it will bond to the external weld 35 to seal the channel that exists between the plates 14 and 16. Plates 16 and 21 are joined by an external weld 36. Partitions 25 are secured by outer fillet welds 38 and welds 40, 41, 42 are deposited in the dry compartments to join internally the outer plates 13, 14, 16, 21. The edge of the sloping portion 22 of the bottom plate 21 is squared to leave a gap between it and the plate 16 so that a fluid tight joint is made by the welds 41, 36, as shown in Fig. 8. After the side panels 48 have been welded the inner corners of the central compartment are welded intermittently. Whenever a T-joint occurs a hole is drilled adjacent one of the dry compartments through the outer plate such as 13, Fig. 4, to expose the edge of the inner plate such as 14 and the welds and weld metal 54 is deposited in the hole which is closed by a cap 55 welded to the outer plate.

Title: Manufacture of dialkoxy substituted glycols
IPC: C07C43/13
Filed: 1937-04-14
Abstract: Dialkoxy substituted glycols are prepared by condensing an alkoxyaldehyde to produce a dialkoxy substituted oxy-oxo-compound and converting the condensation product into the glycol by hydrogenation. The condensation is preferably conducted in the anhydrous state, in the cold, and with an alkaline condensing agent, preferably an alcoholate of the alcohol forming the alkoxy group.  The hydrogenation is effected in the liquid phase with the aid of a catalyst such as a nickel skeleton catalyst prepared by dissolving out with alkali the aluminium or silicon from an alloy of either of these substances with nickel.  In an example, 7 c.c. of a 10 per cent solution of sodium methylate in methanol are dropped slowly and with stirring into 306 gms. of 3-methoxybutyraldehyde at - 5 DEG  C.; the condensation product produced, viz. 2 : 6-dimethoxy-3-formyl-4-oxyheptane, is acidified with acetic acid, diluted with methanol, and treated with hydrogen at 40 DEG  C. in the presence of 20 per cent of a nickel skeleton catalyst to produce 2 : 6-dimethoxy-3-oxymethyl - 4 - oxyheptane.  3 - Ethoxy - butyraldehyde or a mixture of alkoxy-aldehydes may be similarly treated.  The products and their esters and ethers are useful as solvents for lacquers, especially cellulose ester lacquers, paints, perfumes, or cleansing agents.ALSO:Hydrogenation catalysts are prepared by dissolving out with alkali lye the aluminium or silicon from alloys of either of these substances with nickel.
