IPC: F25B15/10
Filed: 1931-07-29
Abstract: 382,654. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Platen-Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) July 29, 1931, No. 21687. Convention date, Aug. 13, 1930. [Class 29.] Absorption systems.-A liquor circulating arrangement for continuous-cycle inert gas systems comprises a pressure chamber 20 located at the lower part of the generator 10, an S-shaped " valve pipe 23 adapted to be sealed and unsealed periodically, a rising pipe 25 leading from the liquor space of the pressure chamber and adapted to vent gas from the valve pipe to the rectifier 13 and condenser 12, and a further liquid seal pipe 24. Liquor is delivered periodically to the absorber 16 through a pipe 21 which exchanges heat at 22 with a return pipe 19 from the absorber to the generator. An inverted U pipe, one leg 28 of which is wide enough to allow gas and liquor to flow together therein, connects the top of the valve pipe with the gas space of the pressure chamber. When pressure is developed in the chamber 20 due to the heating, liquid in the outer pipe of the seal 24 is pressed down, a column is formed in the pipe 25, and liquid is pumped through the pipe 21 to the absorber. This will continue until the opening of the conduit 21 is exposed to the gas space or until the gas pressure in the U tube 27, 28 has forced liquid out of the valve pipe. Gas will then escape from the left side of the valve pipe and through conduit 25 to the condenser, pressures will be equalized, and liquor will flow from the upper part of the generator through the seal 24 to replenish the pressure chamber. An enlargement 30 may be provided in the pipe 25. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter : In order to reduce the total height of the apparatus the superior pressure in the pumping chamber may be balanced by several liquid columns in series. On increase of pressure in the pumping chamber liquor is forced through a pipe into an intermediate chamber which is vented to the condenser. On equalization of pressure liquor will flow from the generator to the intermediate chamber and thence to the pressure chamber. This subject-matter does not appear in the Specification as accepted.

Patent GB-286320-A (GB)
Title: Insulating material
IPC: H01B3/00
Filed: 1926-09-08
Abstract: 286,320. JoffÚ, A. Sept. 8, 1926. Condensers.-A multi-layer insulating material comprises alternating layers of greater and less dielectric strength, the thickness of the better insulating layers being less than 0.01 mm. and preferably about 0.001 mm. The layers may be produced from the same substance by a suitable surface treatment. In the case of linseed oil, a surface contamination of manganese or cobalt compounds, and the application of a temperature of 150‹ to 200‹ C. produces a surface layer of high and an under layer of less insulating strength. A similar surface effect is produced on a substance by passing a direct current through it at a comparatively high temperature. When the alternating layers are formed of different substances, the layers of greater dielectric strength may be applied by squirting or painting suitable solutions and evaporating the solvent. Suitable substances for this purpose are stated to be different types of varnish or resin, boric acid, borax or enamel. The initial supporting layer may be paper, wood, fabric, metal, &c. Specifications 184,436 and 257,080 are referred to.

Abstract: 1292686 Machine for stacking objects on pallets; endless conveyers G G MAGNUSSON K I WEINER and G H GRASVOLL 8 May 1970 [9 May 1969] 22443/70 Headings B8A and B8C In a machine for loading objects in groups on pallets two trays 2, 2, each carrying two rows of six milk cartons 1, are advanced by a conveyer 5 against a two-position stop 11 whereupon a pusher 12 transfers them on to a sloping conveyer 6 for delivery on to a number of rollers 30, driven by an endless chain 32, and up against a stop plug 69, a loading plate 44, reciprocably mounted in an elevator cage 37, then moving transversely of the machine and past a pivotally mounted stripper edge 60 to carry the trays 2, 2 off the rollers 30 and on to the loading plate 44. The cage 37 is then lowered until the loading plate 44 is positioned closely above a pallet 3 located on a chain operated conveyer 9, whereupon the loading plate 44 is retracted into the cage 37 to strip off the two trays 2, 2 on to the pallet 3 and is then raised to its upper position. The next two trays 2<SP>1</SP>, 2<SP>1</SP> are fed, one at a time, the stop 11 being placed in its retracted position, as shown by the dotted line, Fig. 1, so that each tray is rotated through 90 degrees as one edge abuts a projection 19 which interferes with its passage along the conveyer 6. The cage 37 with the extended plate supporting the trays 2<SP>1</SP>, 2<SP>1</SP> is lowered by a predetermined amount to deposit the trays 2<SP>1</SP>, 2<SP>1</SP>, crossways, upon the trays 2, 2. The next pair of trays 2, 2 are loaded in the same manner as the first two, the loading proceeding with alternately turned, and unturned, trays until the pallet 3 is full, the final retraction of the loading plate 44 in its uppermost position operating a vane (65), Fig. 5, not shown, which actuates a switch to energize a motor 38 and move the conveyer 9 one step forward to transfer the loaded pallet out of the machine and replace it with an empty one. The cage 37 has rollers 35, 36 at each side which engage in vertical guides 34, 34, endless chains 39, 53, driven respectively by electric motors 38, 59 transferring movement to the cage 37 and the loading plate 44.

Title: Improvements in or relating to radio communication systems
IPC: H04K1/04
Filed: 1933-08-11
Abstract: 404,574. Wireless signalling. SOC. FRANCAISE RADIO-ELECTRIQUE, 79, Boulevard Haussmann, Paris. Aug. 11, 1933, No. 22448. Convention date, Aug. 12, 1932. [Class 40 (v).] In a secret wireless signalling system employing frequency scrambling, the side-bands representing the several frequencysections of the signal are separated from each other and from the carrier wave and are passed to separate detectors, or to a single push-pull detector, in such a way that inter-modulation between the side-bands is prevented. As applied to a secret telephony system, the voice frequencies are divided into say two ranges, which are transposed and inverted in known manner, and modulated on a carrier wave. At the receiver, the carrier wave is reduced in frequency by heterodyning, and the reduced carrier with its side-bands is then passed through filters which isolate the two sections of the upper side-band, the corresponding sections of the lower sideband, and the carrier. The outer sections of the upper and lower side bands are then applied, together with the carrier, to one detector or pair of detectors, and the inner sections and the carrier to another detector or detectors, each detector being followed by transposing or inverting circuits necessary to restore intelligibility in the combined output. In a modification, the carrier is separated from the sidebands, and all the side-bands are applied jointly through transformer T1 to the grids of push-pull valves V1, V2 in phase opposition, whilst the carrier is applied to the grids in phase agreement, the detected out-put being taken through transformer T3 to a filter F which separates out the several frequencysections prior to their restoration to intelligibility. The receiving system may be employed in conjunction with a single side-band transmission system, only half the number of units being then required. If a suppressed -carrier transmission system is employed, the carrier is supplied at the receiver by manipulation of a pilot wave or by other means. Automatic gain regulation may be employed in the receiver, and an auxiliary automatic regulator may also be used after the frequency-reducing stage for giving a constant amplitude of the carrier.

Title: Improvements in or relating to the distillation of c aromatic hydrocarbons
IPC: C07C7/04
Filed: 1962-06-12
Abstract: In the separation by distillation of a mixture of C8 aromatic hydrocarbons in a series of separate distillation steps, the overhead vapours from one distillation are condensed in indirect heat exchange with the mixture in another distillation step, thereby providing the distillation heat for that step.  In a preferred embodiment, a mixture of ethylbenzene and xylenes is passed to fractionator 2 where ethylbenzene is separated overhead. The xylene bottoms pass to fractionator 7 where ortho-xylene is obtained as bottoms and separated from any higher boiling material in fractionator 9.  The xylene overhead from column 7 is passed through the reboilers of columns 2, 9 and 13 in which latter any lighter material is removed from the condensed xylene overhead from column 7.  The overheads from column 7 are preferably maintained at 30-130 p.s.i.g.  Preferably xylenes from column 13 are crystallized to separate para-xylene and the remainder isomerized and the isomerizate introduced into column 7 by line 6. <PICT:0943890/C3/1>

Abstract: 1,150,604. Endless conveyers; piling material in bulk. SOC. FIVES LILLE-CAIL. 20 May, 1966, No. 22605/66. Headings B8A and B8E. [Also in Divisions B7 and E1] A movable machine for seizing or storing bulk materials comprises a jib 9 carried by a chassis with a longitudinal beam 1 rigidly supported towards one end on a transverse beam 2 and, towards the other end on a second crossbeam 3 by means of a hinge axis 6 parallel to the beam 1 and perpendicular to the crossbeam 3. The beam 2 is supported at its two ends by driving and guiding elements each comprising a self-propelled axle 4 articulated around a horizontal axis 4a encased in a vertical supporting pivot 5 abutting on and rotating in the beam 2. The orientation of each axle 4 is controlled either by a jack or a motor acting on the pivot 5. The beam 3 is similarly supported at its two ends. The jib 9 carries an endless belt conveyer 10 and a bucket wheel 11 and is pivotable about an axle 8 by jack 13 (or by a mast 14, cable winch 15 and cables 16 shown in broken lines). A feedback control device of a known type and comprising an n-position steering control, ensures for each of these positions either the parallel positioning of the axles 4 or their convergence on one of several predetermined points. As illustrated in Figs. 3a, 3b, 3c with a 9-position steering control the appliance may be manoeuvred (a) around three centres in proximity of the end of reach of the conveyer 10, one of these centres, 1, being located on the longitudinal axis of the beam 1 and the other two 1a, 1b situated to either side of the axis; (b) by translatory movement perpendicular to the beam 1 or left or right-handed rotatory movements of relatively short radius and (c) translatory movement in the direction of the beam 1 or rotation to the left or right. Using the centres 1a, 1b alternately the appliance may make angular sweeps combined with an advancing or retreating movement in seizing or storing bulk material or removing the overburden. The appliance may be combined with a further conveyer or appliance articulated to rotate about a vertical axis, Fig. 9 and Figs. 6, 8, 10, 11 (not shown). The beam 3 and axles 4 may be replaced by an axle (28), Figs. 7a, 7b (not shown), equipped with freely running wheels, in which case the centres la, 1b lie on the axis of the axle (28). The machine may be used for piling in heaps, removal of materials, earth-moving operations and exploitation of mines and quarries. The chassis may be tracked instead of wheeled.
