Title: Method for producing unsaturated aldehydes and acids
IPC: C07C45/35
Filed: 1964-09-24
Abstract: Propylene or isobutylene is converted to the corresponding aldehyde and/or acid by reaction with oxygen in the gas phase using a catalyst containing as principal ingredients molybdenum, iron, tellurium and oxygen and the aldehyde produced may also be converted to the corresponding acid during the reaction.  The olefin to be oxidized may contain unsaturated aldehyde and also, hydrocarbons and the reaction may be effected employing a fixed or fluidized bed reactor at atmospheric pressure at 280-450 DEG  C. employing a contact time of 0.1 to 30 seconds.  The mol. ratio of oxygen to olefin or unsaturated aldehyde is preferably in the range 5:1 to 0.5:1 and the reaction mixture may also contain water.  The catalyst, which may contain chromium and a promoter, e.g. phosphorus, boron or vanadium, may be supported on a solid carrier.  In examples, acrolein and acrylic acid are obtained by oxidizing propylene using a catalyst derived from ammonium molybdate, ferric nitrate and tellurium, tellurium dioxide (in one example chromium chloride and phosphoric acid are added during the preparation of the catalyst) and methacrolein and methacrylic acid are obtained by oxidizing isobutylene using a catalyst derived from ammonium molybdate, ferric nitrate, tellurium dioxide and chromium chloride.ALSO:Oxidation catalysts contain molybdenum, iron, tellurium and oxygen.  The catalyst may also contain chromium, preferably in an amount of 10 to 0.1 % by weight.  The catalyst may also contain an acidic promoter such as phosphorus (e.g. in the form of phosphoric acid), boron or vanadium.  The catalyst may be supported on a carrier such as silica, alumina silicon carbide or a silica sol.

Title: Device for the longitudinal locking of cylindrical rods
IPC: F16B7/14
Filed: 1963-10-03
Abstract: 1,056,796. Clamps. E. M. TOROSSIAN. Oct. 3, 1963. No. 39034/63. Heading E2B. A device for locking a rod T Fig. 3 against longitudinal movement, comprises a coil spring R surrounding the rod, such that initial adhesion exists or can be established between the spring and the rod so that the rod is rotatable in one direction, and a fixed abutment 1 which bears on part only of the first turn of the spring, the arrangement being such that when adhesion exists or has been established between the spring and the rod, longitudinal movement in one direction causes the spring to rock about the abutment in the direction of movement so as to increase the pressure of the spring on the rod as the force tending to move the rod, increases. In an example, Fig. 10 of other arrangements (not shown), a spring Rl in its unstressed state is of slightly larger diameter than that of a rod T and is anchored at its ends 107, 108 in rings 109, 110 which are anchored respectively to a frame member 115 and to the rod T, the ring 110 being slidable over the rod and abutting a stop plug 118 secured to the member 115. The arrangement is such that when the rod T is rotated in the direction of the arrow, F4 to thereby stress the spring, the latter becomes locked to the rod and prevents longitudinal movement of the rod in either direction. In another arrangement, Fig. 11 (not shown) for locking two relatively slidable members 0 and 0 1  the member 0 and the rod and spring arrangement corresponds to that of Fig. 10, the rod T extending outwarly of the member 0 1  and being fixed therein by a ring 121 and a flange 122 of a handle P. Angular movement of the handle is limited by a cam and spring loaded plunger arrangement 123..126.

Abstract: 1360498 Dispensing measured quantities of material U PASSAVANT AG 20 Aug 1971 [21 Aug 1970] 39142/71 Heading B8N [Also in Divisions C1 and F1] Apparatus for removing flowable material, e.g. sludge, from a pressurized system, comprises a non-expansible air chamber 7 for receiving the material, an inlet valve 6, a discharge valve 9, and control means for opening and closing the valves. The apparatus is such that, in use, with the valve 6 open and valve 9 closed, material flows into the chamber until the air pressure therein reaches a predetermined value to activate an air pressure actuated switch 11 which causes closure of the valve 6. The valve 9 is then opened to allow material to flow from the chamber into a reservoir 10. After discharge the valve 9 is closed and valve 6 is opened to initiate a further dispensing cycle. Opening of the valve 6 and opening and closing of the valve 9 is controlled by a time switch device 12. The time switch device may be adjustable to vary the time interval between successive openings of the valve 6. The pressure actuated switch 11 is preferably adjustable so that the quantity of material discharged can be varied. The system includes a pump 2 for delivering material at a pressure, e.g. 15-25 atmos. into a chamber 5 via heat exchangers 3. The material passing into the chamber 5 is heated to 180- 220 C. by steam introduced via pipe 13, and the treated material can flow from the chamber 5 through the heat exchangers, to heat the incoming material by conduction to 140- 180 C., to the inlet valve 6 of the apparatus. In a modification two such apparatuses (Fig. 2, not shown) are connected in parallel to the pressurized system and the valves are controlled such that one air chamber is filled whilst the other is emptied.

Abstract: 834,778. Mixing liquids in flow. SEPARATOR A. B. Dec. 5, 1958 [Dec. 12, 1957], No. 39291/58. Class 86 To facilitate the separation of the components of a product; the separation of tall oil from the rest of a water-diluted sulphate soap is one of the examples described; substances which act as emulsion stabilizers and hinder the separation, are destroyed by a reagent which is added continuously to a circulating flow of the product and reagent before the treated product is passed continuously to the separator. As shown, the product is introduced at 7 and mixes in the line 4 with product and reagent already circulating. The mixture passes to a reaction tank 2 and from thence through a pump 5 and line 3 to a reaction tank 1. In the treatment of sulphate soap, 1000 Kg of soap, diluted with water, is introduced per hour at 7, the dilution being such that the tall oil content is 50%. The reagent is sulphuric acid, about 70 Kg per hour being introduced at 6, the quantity being regulated by a pH-meter 10 connected at 11 for automatic control to a dosing device 12. The pH-meter is adjacent the withdrawal line 8 leading to the centrifugal separator 9. The large excess of acid in the tank 1 ensures the precipitation of impurities, especially lignine which emulsifies tall oil, and the lignine is not redissolved when it mixes with the freshly introduced soap, provided that the pH- value is kept below 4. Other examples are the separation of soap stock from peanut oil and the separation of fatty material from finely ground fish, e.g. herrings.

Patent GB-817149-A (GB)
Title: A method for the purification of acetone
Filed: 1957-12-24
Abstract: Acetone, which is contaminated with aldehydes, acids and esters, is purified by intimately mixing with a volumetric excess of 10-30 per cent w/w aqueous caustic solution, separating the phases before any substantial condensation of the acetone has taken place and distilling the acetone.  The crude acetone may be derived, for example, from the acid cleavage of cumol hydroperoxide.  The mixing is preferably effected in a centrifugal or turbo pump using at least 5 parts by volume of alkali to 1 part of acetone.  After the separation step the alkali may be recycled, being replaced by fresh from time to time and the used alkali withdrawn.  Water is preferably added to the acetone before treatment in order to replace that absorbed by the acetone from the alkali.  It is expedient to add water (e.g. 1-2 per cent based on the acetone) to one of the lower plates of the distillation column above the inlet level.  An example is given.

Abstract: 868,404. Telephone transmission systems. WESTERN ELECTRIC CO. Inc. Dec. 2, 1959 [Dec. 19, 1958], No. 40900/59. Class 40 (4). [Also in Group XIX] A pair of binary counters are fed by a common impulsing circuit, the outputs of the component parts of the one counter being fed to sets of coincidence gates associated respectively with the component parts of the two counters so that impulses from the common impulsing circuit advance both counters, the arrangement being such that the connections between corresponding stages of the two counters can be selectively inverted so that one counter can be set to a predetermined amount in advance of the other. The output of each part 1 and 0 of each bi-stable element 13-17, Fig. 1, in the first counter 10 is fed back through a delay circuit 18 to a coincidence gate 21-30 feeding impulses from a common input 20 to the opposite input part R and S, respectively, of the same bi-stablo element. The outputs from part 1 are also fed to all coincidence gates of higher significance. By this means transfer from one stage to the next is effected at the same time as the input. The advance pulses are much shorter than the delay imposed by the delay circuits. The counter 10 is connected to a similar counter 12 through switches 151-155. By reversing selected switches the counter 12 may be advanced by a number corresponding to said switches. Application to telephone system. Fig. 2 shows a circuit for timing the connection signals in a time assignment speech interpolation (T.A.S.I.) system, in which a signal source 78 is connected to a transmission line 79 only when signals are actually being generated. When connection is to be effected an identification tone must be sent for a closely timed interval. The switches in circuit 11 are set to provide a numerical difference between counters 10 and 12 whereby that number of pulses from source 70 is counted during this time interval. When signal source 78 becomes active bi-stable device 82 is reversed and at the same time a pulse is applied to commutator 74. Bi-stable device 82 connects the identifying tone source 85 to the transmission line 79. The pulse over commutator 74 causes the number in counter 10 to be registered at 61 on a magnetic drum. This number is read at 67 and compared with the number in counter 12 in comparator 69. After the predetermined time the recorded number agrees with the number in counter 12 and the comparator energizes circuit 73 to erase the record and over commutator 75 restores bi-stable device 82 so cutting off tone. The same signal operates T.A.S.I. switch 87 to connect the signal source to line. The mechanical switches 151-155 of Fig. 1 may be replaced by the logical circuitry shown in Fig. 3, in which the digit appearing on conductors 90, 91 may be selectively inverted by the potentials appearing on conductors 92, 93. The prior art is represented by references to Specifications 845,174 and 861,515.
